What is a Patent for Multi-transmission time interval grants (TTI): Time domain resource allocation (TDRA).
Certain elements of this disclosure provide ways to implement time domain resource allocation (TDRA), for multiple-transmission times interval (TTI), grants.
Field of the Disclosure
The present disclosure is related to wireless communications, and specifically, techniques that allocate time-domain resources (TDRA) that are used for multi-transmission times interval (TTI) that allows.
Description of related art
A variety of wireless communication systems are used to offer a variety of telecommunications services, such as videos, data, messaging and broadcasts. These wireless communication systems may utilize multiple-access technology that allows communications with multiple users through sharing system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple-access systems include 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) systems, LTEAdvanced (LTE-A) systems, code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrierfrequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems, to name a few.
A wireless multiple-access communication network can have several base stations (BSs) that can simultaneously enable communication between multiple devices. These are known as userequipments or UEs. An eNodeB (eNB) is a set of base stations that may be utilized in an LTE network or LTE-A. In other instances (e.g., in a next generation radio, a brand new radio (NR), or a 5G-based network), a wireless multiple access communication system may include anumber of distributed units (DUs) (e.g., edge units (EUs), edge nodes (ENs), radio heads (RHs) as well as smart radio heads (SRHs), transmission reception points (TRPs) as well as.) in communication with a number of central units (CUs) like central nodes (CNs) or accessnode controls (ANCs) or accessnode control (ANCs), etc. A set of one or more DUs may connect to a CU to identify access nodes. This may be the following: BS, Next Generation NodeB (gNB, gNodeB), or TRP. A BS or DU can communicate with a set ofUEs on downlink channels (e.g. to transmit messages between an BS or DU to a UE) as well as uplink channels (e.g. for transmissions from an UE to a BS or DU).
These multiple access technologies were implemented in various standards for telecommunications to create a common protocol that allows various wireless devices to communicate at different levels. A brand new radio (e.g. 5G NR) is an example of a standard for telecommunications. 3GPP has released the NR standard, which is an enhancement to the LTE mobile standard. NR is designed to better support mobile broadband Internet access by enhancing the efficiency of the spectral spectrum, decreasing costs, improving services, using new spectrum, and better integrating with other standards that are open, that use OFDMA with an cycled prefix (CP) on the downlink (DL) as well as on the uplink (UL). To these ends, NR supports beamforming, multiple-inputmultiple-output (MIMO) antenna technology, and carrier aggregation.
As the need for broadband services via mobile networks increases there is a need to further improve NR and LTE technology. These enhancements should, at a minimum, be applicable to multi-access technologies as well as the standards for telecommunications that utilize these technologies.
Every one of the disclosed systems, methods or devices includes a number of aspects. But, no single element is responsible for all the desirable characteristics. Without limiting the scope of this disclosure as stated in the claims, a few aspects will be reviewed briefly. After considering this discussion, and particularly after reading the section entitled “Detailed Description” one will understand how the features of this disclosure provide advantages that include improvedcommunications between access points and stations in a wireless network.
Certain features of the method allow wireless communication through the Base Station (BS) to be achieved. The method includes allocating time domain resources to a plurality physical uplink shared channel transmissions (PUSCH) that are based on the TimeDomain Resource Allocation pattern (TDRA) that is selected from an TDRA Table specifically designed to grant multi-PUSCH. DCI provides an indication of the TDRApattern from the TDRA.
Certain aspects offer a method to wirelessly communicate with the User Equipment (UE) according to certain aspects. The method generally includes receiving downlink control information (DCI) scheduling a plurality of physical uplink shared channel (PUSCH) transmissions,wherein time domain resources are allocated for the plurality of PUSCH transmissions according to a Time Domain Resource Allocation (TDRA) pattern selected from a TDRA table designed for multi-PUSCH grants and the DCI comprises an indication of the TDRApattern, determining, based on the indication, the TDRA pattern from the TDRA table, and determining, based on the determined TDRA pattern, the allocation of the time domain resources for the plurality of PUSCH transmissions.
To the accomplishment of the above-mentioned and related goals to achieve the above and related goals, the various aspects comprise the features hereinafter detailed and pointed out in the claims. The attached drawings as well as the description that follows show illustrations of the different aspects. These are examples, however, of but some of the many ways in which the concepts of the various aspects could be utilized.

What is a patent?
Patents are issued by the government in order to protect an invention. It gives the inventor the right to develop, utilize and sell the idea. Society gains when new technology is introduced for sale. The benefits can be directly realized as individuals are able to accomplish previously unattainable feats or via the opportunities for economic growth which innovation can bring (business growth, employment).
Many pharmaceutical firms and university researchers are seeking patent protection for their research and developments. Patents are granted for a product, process, or method of making new materials. In order to be granted protection under a patent an invention has to be innovative, novel and not apparent to other people within the same subject.
Patents honor inventors who have commercially successful inventions. They act as a motivator for inventors to invent. Small businesses and inventors can rest assured that they will get an income from the investment they make in technology development via patents. They can earn money by their work.
Patents are a crucial part of businesses with the ability to:
Protect your innovative products and services.
Increase the value, popularity, and appeal of your products on the market;
Your business and your products should be distinguished from others;
Access technical and business knowledge and information;
Beware of accidentally downloading third-party content or losing important information, original outputs, or any other creative output.
Patents transform inventors’ information into a tradeable asset, which creates new opportunities for employment creation and business growth by licensing or joint ventures.
Investors in the commercialization and development of technology will find small-scale businesses that have patent protection appealing.
Patenting can lead to innovations and new ideas. This information can encourage creativity and could be eligible for protection under patents.
Patents can be used to stop untrustworthy third parties from profiting through the work of inventions.
Commercially successful patent-protected technology revenues could be used to finance technological research and development (R&D) and improve the chances of developing better technology in the coming years.
You can use the intellectual property rights of your company to convince investors and lenders that your product has real commercial value. Sometimes, one patent could open the door to a variety of financing possibilities. Patents can be used along with other IP assets as collateral or security for financing. Investors can also see the patents you own to increase their company valuation. Forbes and other sources have pointed out that every patent could add between $500,000 and one million dollars to your company’s valuation.
A properly-drafted business plan is crucial for new businesses. It must be built on IP and show what your service or product stands out. Investors are also impressed if you have IP rights are secure or are on the verge of becoming secure and if they are supportive of your business plan.
It is vital to protect an invention before applying for patent protection. Making an invention public before filing it can often destroy its novelty and make it ineligible for patent protection. The filing of disclosures prior to filing, for example, for investors, test-marketing, or any other business partners, is best done following the signing of a confidentiality agreement.
There are several types of patents, and understanding them is essential to protecting your invention. Utility patents are for the development of new methods and machines. Design patents cover ornamental designs. Patents for utility are the most effective since they shield the proprietor from copycats as well as other competitors. Most often they are granted for modifications or improvements to existing inventions. Utility patents can also be used to enhance or modify existing inventions. For instance, a procedure patent will cover acts or methods for performing a specific act, whereas chemical compositions will comprise an assortment of components.
What is the length of time a patent will last? Although utility patents are valid for 20 years from the date of their initial filing, they are able to be extended through delay in the patent office.

How to Search for Patents
Patent searches are the very first step towards obtaining your patent. You can do a google patent search or do a USPTO search. Patent-pending refers to the product that has been covered by the patent application. It is possible to search the public pair to find the patent application. Once the patent office approves the patent application, you are able to do a patent number search to locate the patent that was issued, and your product has been granted patent. You can also utilize the USPTO search engine. See below for details. A patent lawyer or attorney can help you through the process. In the US patents are granted by the US trademark and patent office or by the United States patent and trademark office, which also reviews trademark applications.
Are you interested in finding other similar patents? Here are the steps to follow:
1. Create a list of terms for your invention according to its function and composition or usage.
Write down a short detailed description of the invention. Avoid using generic terms like “device,” “process,” and “system.” Instead, think about synonyms for the terms you chose initially. Then, take note of important technical terms as well as keywords.
To help you identify terms and keywords, you can use the questions below.
- What is the goal of the invention? Is it a utilitarian device or an ornamental design?
- Does the invention consist of a method of making something or performing a function? Does it constitute an item?
- What is the composition of the invention? What is the physical structure of the invention?
- What is the goal of the invention?
- What are the terms used in technical terminology and keywords that describe the essence of an invention? To find the right terms, refer to a technical dictionary.
2. Utilize these terms to locate relevant Cooperative Patent Classifications on the Classification Text Search Tool. To determine the best classification to your invention, scan the class scheme of the classification (class schedules). Think about substituting the words that you’re using for describing your invention, if you do not receive any results from your Classification Text Search with synonyms like the ones you used in step 1.
3. Go through 3. Check the CPC Classification Definition to confirm the validity of the CPC classification you have found. The link to the CPC classification definition will be provided in the event that the title of the chosen classification is a blue square with a “D” to its left. CPC classification definitions will help you determine the applicable classification’s range so that you can select the one that is most appropriate. Additionally, these definitions can include some tips for searching and other information that could be helpful in further research.
4. Retrieve patent documents with the CPC classification from the Patents Full-Text and Image Database. You can search and find the most relevant patent documents by focusing first on the abstract and drawings representative of.
5. Take advantage of this list of most relevant patent publications to look at each one in depth for any similarities to your own invention. Be sure to read the claims and specifications. It is possible to find additional patents by consulting the patent examiner and the applicant.
6. Find patent applications published in the public domain using the CPC classification you selected in Step 3 in the Applications Full-Text and Image Database. The same method of searching is applicable to step 4. You can filter the results of your search to find the most pertinent patent applications by looking over the abstracts and drawings for every page. Then, you must carefully review the patent applications published with particular attention paid to the claims as well as additional drawings.
7. You can look up additional US patent publications using keyword searching in the AppFT and PatFT databases, and also the classification search of patents that are that are not issued by the United States per below. Also, you can utilize web search engines to search for non-patent-related documents that describe inventions in the literature. For example:
- Add keywords to your search. Keyword searches may turn up documents that are not well-categorized or have missed classifications during Step 2. For example, US patent examiners often supplement their classification searches with keyword searches. Think about the use of technical engineering terminology rather than everyday words.
- Search for foreign patents using the CPC classification. Then, re-run the search using international patent office search engines such as Espacenet, the European Patent Office’s worldwide patent publication database of over 130 million patent publications. Other national databases include:
- European Patent Office (EPO) provides esp@cenet to access a network of Europe’s patent databases with access to machine translation of European patents.
- Japan Patent Office (JPO) – with access to machine translations of Japanese patents.
- World Intellectual Property Organization (WIPO) offers PATENTSCOPE with a full-text search of published international patent applications and machine translations for some documents, as well as a list of international patent databases.
- Korean Intellectual Property Rights Information Service (KIPRIS)
- State Intellectual Property Office (SIPO) with machine translation of Chinese patents.
- Other International Intellectual Property Offices with online patent databases include Australia, Canada, Denmark, Finland, France, Germany, Great Britain, India, Israel, Netherlands, Norway, Sweden, Switzerland, and Taiwan.
- Search non-patent literature. Inventions can be made public in many non-patent publications. It is recommended that you search journals, books, websites, technical catalogs, conference proceedings, and other print and electronic publications.
To review your search, you can hire a registered patent attorney to assist. A preliminary search will help one better prepare to talk about their invention and other related inventions with a professional patent attorney. In addition, the attorney will not spend too much time or money on patenting basics.
