Control plane Section Type Message indicates an extension message for a section that has a field named numZeroPadBin which indicates the number of zero padding bins that are to be added following an indication in the section header in the control plane section type message for FFT/iFFT. The control plane section type message may be the following: a Section Type 1 message, a Section Type 3 message, or an Section Type 5 message, and could be linked to the MBSFN subframe. The numZeroPadBin field will be determined by the SCS FFT size, CP combination of ECP/NCP in a subframe, or the slot.

Improvements are needed to the control signal messaging interface between radio devices (RU)and the central unit or distributed units (DU) of an Open Radio Access Network wireless communication system (O-RAN). Without a clear definition of the zeropadding needed to create the O-RAN front-haul interface for certain scenarios such as Multimedia Broadcast Multicast Services (MBMS) It is not easy to determine how the zeropadding works for the inverse Fast Fourier Transform/Fast Transform bins.

A control plane section type message refers to a section extension message that includes a field numZeroPadBin indicating a number of padded bins that are zero to be added to an indication in the section header of the control plane section type message for FFT/iFFT. A control plane section type type message could be one of the following examples: a Section Type 1 message; it could also be a Section Type 3 or Section Type 5 message. It could also be associated with an MBSFN subframe. The numZeroPadBin number is calculated based on the SCS, FFT Size and CP combination NCP/ECP inside a subframe or a slot.

Other technical characteristics may be readily apparent to one skilled in the art from the following figures as well as descriptions and claims.

What is a patent?

Patents are granted by the government in order to protect the invention. It grants the inventor the exclusive right to create, use and market the idea. Society gains when new technologies are brought to the market. Benefits can be realized in direct terms, as it allows individuals to achieve previously unattainable things. Or indirectly due to the opportunities for economic growth (business growth and employment) that the innovation offers.

Patent protection is demanded out by many pharmaceutical companies and university researchers for their research and development. Patents can be granted for products, processes, or method for making new materials. Patent protection is granted to any invention that is valuable, novel, and not already known by others in the same field.

Patents give inventors a reward for commercially profitable inventions. They serve as a motivator for inventors to invent. Small-scale businesses and inventors can be assured that they will get an income from the investment they make in technology development through patents. They could earn a decent income by their work.

Companies that are able to:

Secure your products and services.

Enhance the visibility and worth of your products ‘ presence on the market

Make your brand stand out from the competition.

Access to business and technical knowledge and data;

Beware of the possibility of accidentally using proprietary third-party content, or losing your valuable information, innovative outputs, or other creative output.

Patents transform inventors’ information into a tradeable asset, which creates new opportunities for employment creation and expansion of businesses through licensing or joint ventures.

Small-scale businesses with patent protection will be more attractive to investors in the commercialization of technology.

Patenting can lead to new ideas and inventions. The information you create may be protected by patents.

Patents can be used to serve as a deterrent to untrustworthy third parties profiting from an invention’s efforts.

Revenues from patent-protected technology that are commercially successful could be used to finance technological research and development (R&D) that will boost the likelihood of improved technology in the future.

Intellectual ownership of property can be used to convince lenders and investors that there are legitimate opportunities to market your product. A powerful patent can provide numerous financing options. Patents and other IP assets can be used as collateral or security to finance debt. Investors can also see your patent assets to increase the value of your company. Forbes and other publications have reported that each patent can add between $500,000 and a million dollars in company valuation.

Start-ups need a well-constructed business plan that leverages the IP to demonstrate that your product or service is distinctive superior, innovative, or superior. In addition, investors will be impressed when you demonstrate that your IP rights are secure or in the process of becoming secure and that they align with your business strategy.

It is crucial to keep your invention secret until you apply for patent protection. Making an invention public prior to filing could often erode its originality and render it patent-infringing. Disclosures that are filed prior to filing, like for investors, test-marketing or any other business partners, is best done after signing a confidentiality agreement.

There are several types of patents and knowing these is vital to safeguard your invention. Utility patents are for new processes and machine creations. Design patents cover ornamental designs. Patents for utility are the best option and protect the owner against copies and competitors. In most cases, utility patents are issued for improvements or modifications to existing inventions. Patents issued under utility can be used to improve or modify existing inventions. A process patent will be a way to describe the actions or methods to perform a particular action. However, a chemical composition would include the combination of components.

What is the average length of the patent? Utility patents are valid for 20 years after the earliest filing date, however, their expirations may be extended due to patent office delays for instance.

Do you want to protect your idea? Patents are only granted to applicants who are the first to file, therefore you need to file your patent application quickly. Call PatentPC now to have your patent application filed!

When drafting an application for patents it is recommended to conduct an internet search for patents, since the search can provide an understanding of other people’s thoughts.

This will help you to comprehend the scope of your invention and prepare for the filing of the patent application.

How to Search for Patents

The first step in getting the patent you want is to conduct a patent search. You can do a google patent search or do a USPTO search. After the patent application has been submitted, the product that is that is covered by the patent application could be called patent-pending, and you can find the patent application online on the public pair. Once the patent office approves the patent application, you will be able to do a patent number search to locate the issued patent. Your product will now be patented. You can also use the USPTO search engine. See below for details. It is possible to seek help from a patent lawyer. Patents granted in the United States are granted by the US trademark and patent office or the United States patent office. The office also examines trademark applications.

Are you interested in finding other similar patents? Here are the steps:

1. Think of terms to describe your invention, based on the purpose, composition and application.

Write down a concise and precise description of your idea. Be sure to avoid using terms that are generic such as “device,” “process,” and “system.” Think about synonyms for the terms you chose initially. Also, make note of key technical terms and key words.

Utilize the following questions to help you determine keywords or concepts.

  • What is the objective of the invention Is it a utilitarian device or an ornamental design?
  • Is the invention a method of creating something , or carrying out a function? Is it an object?
  • What is the structure of the invention? What is the physical makeup of the invention?
  • What is the goal of this invention?
  • What are technical terms and keywords that describe the nature of an invention? To help you find the correct terms, consult an online dictionary of technical terms.

2. These terms allow you to find relevant Cooperative Patent Classifications at Classification Search Tool. To find the most appropriate classification to your invention, go through the classification’s class Schemes (class schedules). If you don’t get any results from the Classification Text Search, you might want to think about substituting the words to describe your invention with synonyms.

3. Examine the CPC Classification Definition for the CPC Classification Definition to verify the accuracy of the CPC classification you’ve discovered. If the chosen classification includes a blue square with an “D” at its left, clicking on the hyperlink will direct you to the CPC classification definition. CPC classification definitions can be used to determine the scope of the classification and therefore you’re certain to choose the one that is appropriate. In addition the definitions may include search tips and other suggestions that could be helpful in further research.

4. The Patents Full-Text Database and the Image Database allow you to retrieve patent documents that include the CPC classification. You can review and select the relevant patent publications focusing first on the abstract and the drawings that are representative.

5. This collection of patent publications is the best to check for similarity to your idea. Be sure to read the specification and claims. Refer to the applicant and patent examiner for additional patents.

6. You can find the patent application that has been published and fit the CPC classification you selected in Step 3. You can use the same search strategy as Step 4, narrowing your results to the most relevant patent application through the abstract and illustrations on every page. After that, take a close look at the patent applications that have been published with particular attention paid to the claims as well as additional drawings.

7. Locate additional US patent publications by keyword searches in PatFT and AppFT databases, searching for classification of non-U.S. patents as described below, and searching for non-patent patent disclosures in the literature of inventions using internet 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.
