    Abstract: A method includes determining, based on a length of to-be-encoded information bits and a code rate, a code length N after encoding; determining, based on N, a minimum segment code length and a maximum segment code length, a reserved segment quantity of each type of segments in segments of b−a+1 types of segment code lengths and a reserved code length corresponding to N, where the minimum segment code length is 2{circumflex over ( )}a, and the maximum segment code length is 2{circumflex over ( )}b; determining a segment quantity of each type of segments based on N, the reserved code length, a segment code length of each type of segments, and the reserved segment quantity, where N corresponds to S segments, and a segment code length of an ith segment in the S segments is greater than or equal to a segment code length of an (i+1)th segment in the S segments.

    Abstract: This application provides a physical layer control information transmission method and apparatus. In the method, a first communication apparatus may obtain first physical layer control information. The first physical layer control information may include N pieces of first information, where N is greater than or equal to 2. The first communication apparatus may obtain target first information from the N pieces of first information. The target first information may indicate a frequency domain resource of a first channel. The first communication apparatus may estimate the first channel based on the target first information. The first communication apparatus may obtain second physical layer control information. The second physical layer control information includes signaling information that may be used by the first communication apparatus to send feedback information corresponding to the first channel. The first communication apparatus may send the feedback information based on the second physical layer control information.

    Abstract: Embodiments of this application provide a wireless communication method and an apparatus. The method includes: A first communication apparatus receives first information, where the first information indicates a determining threshold of a parameter in a first parameter set, and the first parameter set includes at least one of the following parameters: location information, delay information, a timing advance rate, a rate of the timing advance rate, a Doppler value, a Doppler rate, and remaining coverage time. The first communication apparatus determines, based on the first information, whether an access condition is met, and performs random access when the access condition is met. This avoids a random access failure in a current cell and re-access in a next cell due to random access performed when the condition is not met.

    Abstract: A terminal apparatus receives a parameter that is configured by a network apparatus and that is used to calculate an update period, where the update period is used to indicate time at which the terminal apparatus receives an uplink time-frequency synchronization parameter. The terminal apparatus receives an updated uplink time-frequency synchronization parameter based on the update period. The network apparatus configures the parameter for calculating the update period, so that the terminal apparatus can update the uplink time-frequency synchronization parameter in time.
