Abstract: A communication method and a communication apparatus are provided. The method includes: A first device receives first information, determines a target TR pattern based on the first information, and sends information or demodulates received information based on the target TR pattern, where the target TR pattern is a sub-pattern of a longest TR pattern, and the longest TR pattern includes a set of sub-carriers used as reserved tones. The longest TR pattern may include a plurality of TR sub-patterns of different lengths. For example, a first TR pattern of a first length is a sub-pattern of the longest TR pattern, and a second TR pattern of a second length is also a subset of the longest TR pattern. The TR sub-patterns of different lengths may correspond to different carrier bandwidths or quantities of RBs.

Abstract: Embodiments of this application relate to the field of communication technologies, and provide a timing offset parameter update method, a device, and a system, to help reduce signaling overheads when a terminal device updates a value of a timing offset parameter. The method includes: A terminal device obtains a timing advance adjustment variation corresponding to the terminal device, where the timing advance adjustment variation is a difference between a timing advance adjustment amount currently used by the terminal device and a timing advance adjustment amount used at a previous moment. The terminal device determines whether an absolute value of the timing advance adjustment variation is greater than or equal to a first threshold. If the absolute value is greater than or equal to the first threshold, the terminal device sends, to a network device, first indication information used to indicate an update regularity of a timing offset parameter.

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.
