Wireless communication is possible using disclosed apparatuses, systems and methods. A base station can communicate with a variety of user equipments (UEs) without allocating spectral resources to the UEs for communicating schedule requests. A base station could recognize a scheduling request from one of the many UEs. The scheduling request may include an RF signal that is which is based upon a spreading sequence. A scheduling request could identify the identity of the requester UE. However it should not contain any other information. The base station could provide spectral resources to the asking UE upon detecting an incoming scheduling request.

Multiple user equipments (UEs), which connect to a base station, can make up an wireless communication network. Different spectral resources could be allocated by the base station different UEs to facilitate uplink and downlink communication. The base station could be able to “know” when it has data to transmit to the user for downlink communication. This may enable the base station to allocate spectral resources efficiently and communicate with low latency. In the case of uplink communication, the UE could have data to transmit before the base station “knows”.

The base station allocates uplink resources to UEs in order to offer “grant-free” and “configured grant” uplink transmissions. It is possible to have low latency for UEs using uplink resources already allotted. However, UEs may not have enough data to transmit, and so scarce spectral resources can be under-utilized. For “grant-based uplink transmissions”, the base station allocates spectral resource for uplink transmissions to UEs as needed. A UE might make a scheduling request (SR) to notify the base station that it wants to transmit information. The base station may respond with an acknowledgement signal, thereby allocating spectral resources for the UE to use for the transmission of data. While grant-based strategies may be more efficient than those without grants, they can delay data transmission due to the time required to ask for and allocate resources.

Wireless communication is possible using the disclosed apparatus. One embodiment, is the base station. A base station can be configured to connect to various users’ equipment (UEs) in some embodiments. Further it is possible for a base station to be set up to communicate with UEs without assigning spectral resources to UEs for communicating scheduling requests. A base station may be set up to recognize a request for scheduling from one of the plurality UEs. A scheduling request could also comprise a spread spectrum signal that is based on a spreading sequence. In various ways the scheduling request can provide an identity to the requester UE but without indicating anything other beyond the identity. A base station may be configured to supply the requesting UE in response to the scheduling request.

Methods are disclosed for wireless communication. One method includes communication with a plurality UEs, without allocating spectral resource to them to communicate scheduling requests. In certain embodiments, a methodincludes detecting a scheduling request from one of the requesting UEs from the multiple UEs. The scheduling request may also include an asymmetric signal that is based on a spreading sequence. The scheduling request may identify the asking UE in various embodiments. A method could include the grant of spectral resource to a requesting UE as a response to the detection of a scheduling demand.

An apparatus, in another embodiment, has a means of communicating with a plurality of UEs without assigning spectral resources to UEs for communicating scheduling requests. An apparatus can include a mechanism to detect a scheduling request from one of the UEs. The scheduling request may also include the spread spectrum signal which is based on a spreading sequence. In various instances the scheduling request can indicate an identityfor the requesting UE, but not provide additional information other that the identity. An apparatus could include a means to grant spectral resources to the seeking UE when it detects an incoming scheduling request.

What is a patent?

Patents are granted by the government in order to protect the invention. It grants the inventor the exclusive rights to develop, use and sell the invention. Society is benefited when new technologies are brought for sale. These benefits could be realized directly as people can achieve previously impossible feats or through the opportunities for economic growth that innovation provides (business expansion, job creation).

A lot of pharmaceutical companies and researchers at universities seek patent protection to protect their research and development. Patents may cover the physical or abstract nature of a product or process or a technique or composition of material that are new to the field. Patent protection is granted to an invention that is useful, novel, and not previously known to others in the same field.

Patents are a way to honor inventors who have commercially profitable inventions. They provide a motivation for inventors to create. Patents permit entrepreneurs and inventors to be confident that there’s the possibility that they’ll receive a return on their time, effort and money spent on the development of technology. They can make a living by their work.

Patents play essential roles in companies, and they can:

Secure new products and services that are innovative;

Increase the visibility and value of your products ‘ presence on the market

Make your company and products stand out from the competition;

Access business and technical expertise and data;

Avoid the danger of using proprietary third-party content, or losing your important information, creative outputs, or other creative output.

Patents convert knowledge of the inventor into a marketable asset, which opens up new opportunities to create jobs through licensing and joint ventures.

Investors who are involved in the commercialization and development of technology will find small businesses with patent protection appealing.

Patenting can generate innovative ideas and inventions. This information can promote innovation and may qualify for protection under patents.

Patents are a way to stop untrustworthy third-party companies from earning through the work of inventions.

Revenues from patent-protected technology that are commercially successful can be used to finance research and development (R&D) and improve the chances of developing better technology in the near future.

Intellectual property ownership is a way to convince lenders and investors that there are genuine opportunities to market your product. Sometimes, a single patent can open the door to multiple financing opportunities. Patents can be used in conjunction with other IP assets as collateral or security financing. Investors may also be able to see the patents you own to increase the value of your business. Forbes and others have pointed out that each patent could increase anywhere from $500,000 to a million dollars in company valuation.

A well-designed business plan is essential for start-ups. It should be based on IP and explain what your service or product is distinctive. Investors will also be impressed if your IP rights are secure or in the process to becoming secure, and that they are in line with your business strategy.

It is essential to keep an invention secret until you apply for patent protection. The public divulging an invention could frequently devalue its originality and make it invalid. Disclosures that are filed prior to filing, like for investors, test-marketing, or any other business partners, must be done after signing a confidentiality agreement.

There are numerous types of patents. Knowing them is essential for protecting your invention. Patents for utility are used to protect the development of new methods and machines. Design patents cover ornamental designs. Utility patents are the best because they shield the proprietor from copycats and other competitors. In most cases the utility patent is issued for alterations or improvements to existing inventions. Utility patents also cover improvements and changes to existing inventions. A process patent could be a way to describe the actions or methods of performing a specific act. A chemical composition could be a combination of components.

What is the length average of patents? Although utility patents are valid for 20 years from the date of their initial filing, they can be extended through delay at the Patent Office.

Are you looking for similar patents? Here are the steps:

1. Create a list of terms for your invention, based on its purpose and composition or use.

Write down a brief and precise description of your idea. Do not use generic terms such as “device,” “process,” and “system.” Instead, consider synonyms to the terms you selected initially. Also, make note of key technical terms and keywords.

Use the questions below to help you identify keywords or concepts.

  • What is the purpose of the invention Is it a utilitarian device or an ornamental design?
  • Invention is a method to make something or carry out an action? Is it an item?
  • What is the composition of the invention? What is the physical composition of the invention?
  • What’s the objective of this invention?
  • What are the terms in the technical field and keywords used to describe the nature of an invention? A technical dictionary will help you locate the right terms.

2. Use these terms to find pertinent Cooperative Patent Classifications for your invention at the Classification Text Search Tool. To determine the best classification to your invention, look through the classification’s class Schemes (class schedules). If you don’t see any results from the Classification Text Search, you may want to consider replacing the words to describe your invention using synonyms.

3. Examine 3. Go over the CPC Classification Definition to determine the relevancy of the CPC classification that you have discovered. The link to a CPC classification definition will be provided when the classification you have selected is a blue square with a “D” on its left. CPC classification definitions will assist you in determining the classification’s scope so that you can pick the one that is the one that is most appropriate. In addition, these definitions can include some tips for searching and other information which could be helpful for further research.

4. The Patents Full-Text Database and the Image Database allow you to search for patent documents that have the CPC classification. You can search and find the relevant patent publications by looking first at abstract and the drawings that are representative.

5. Utilize this list of most relevant patent publications to examine each in detail for the similarities to your idea. Pay close attention to the specifications and claims. Refer to the applicant and patent examiner to obtain additional patents.

6. You can find published patent applications that match the CPC classification you picked in Step 3. You may also employ the same strategy of searching you utilized in Step 4 to narrow down your results to just the most relevant patents by reading the abstracts and drawings on every page. After that, take a close look at the patent applications that have been published, paying particular attention to the claims as well as additional drawings.

7. Find other US patents by keyword searches in PatFT and AppFT databases, searching for classification of non-U.S. patents per below, and searching non-patent publications of inventions with web search engines. Here are a few examples:

  • 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:
  • 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.
