Abstract: Embodiments of this application disclose a communication processing method, including: A first communication device determines a first tone reservation pattern. The first communication device communicates a data signal by using the first tone reservation pattern. The first tone reservation pattern is determined based on a first bandwidth part BWP, or the first tone reservation pattern is determined based on a first beam. The first bandwidth part is used for communicating the data signal between the first communication device and a second communication device, and the first beam is used for communicating the data signal between the first communication device and the second communication device. It can be learned that the first tone reservation pattern is more suitable for the first communication device and the second communication device.

Abstract: Embodiments of the application provide a method for rate matching in a wireless communication network. A device obtains K information bits and a target code length M of a polar code, determines, according to a minimum value of a set of values, a mother code length N1, polar encodes the K information bits to obtain an encoded sequence of N1 bits, obtains a target sequence of M bits from the N1 bit encoded sequence, and outputs the M-bit target sequence.
