Problems solved by technology

However, PC-Polar is still not optimal, for example, it may have a high false alarm rate (FAR) and its performance is not optimal
In addition, PC-Polar's codeword formation and check bits are not very efficient because it cannot protect the information bits

Embodiment Construction

[0022] In the following description, numerous details are set forth for purposes of explanation. However, one of ordinary skill in the art will recognize that the present invention may be practiced without the use of these specific details. Thus, the present invention is not intended to be limited to the embodiments shown but is to be accorded the widest scope consistent with the principles and features described herein.

[0023] It should be understood that the terms "first", "second", etc. are only used to distinguish one element from another element. In fact, the first element can also be called the second element, and vice versa. In addition, it should also be understood that "comprising", "comprising" is only used to describe the existence of stated features, elements, functions or components, but does not exclude the existence of one or more other features, elements, functions or components.

[0024] For ease of explanation, some embodiments of the present invention ar...

Abstract

Embodiments of the present disclosure relate to a method and apparatus for data processing in a communication system. For example, a method includes: generating an error-checking code to be used based on desired performance; distributing bits in the error-checking code among information bits to be encoded; and The error checking code is used for polar coding. Embodiments of the present disclosure also provide a communication device capable of implementing the above method.

Description

technical field [0001] Embodiments of the present disclosure relate generally to communication systems, and in particular to methods and devices for data processing at sending and receiving devices of a communication system. Background technique [0002] Polar codes have been proposed for enhanced mobile broadband (eMBB) control channels. Polar codes are also candidates for channel coding for machine type communications (mMTC). Compared with other channel coding schemes, polar codes have advantages such as low complexity and being able to approach capacity. Therefore, for example, in the fifth generation (5G) mobile communication system, polar coding will play an important role. [0003] For polar codes, frequently used decoding schemes are list-based schemes or cyclic redundancy check (CRC)-assisted list-based schemes. where list is a representation of the decoding path. That is, for a scheme whose list size is L, L branches should be reserved during decoding. Usually,...
