Abstract: The disclosure provides communication methods and apparatuses. One example method includes that after receiving a cell handover command, a terminal device determines discontinuous reception (DRX) configuration information of a target cell. The DRX configuration information of the target cell is consistent with DRX configuration information of a source cell. The terminal device exchanges data at least with the source cell based on the DRX configuration information of the source cell, or with the target cell based on the DRX configuration information of the target cell.

Abstract: This application provides a communication method in a dual-connectivity mode. In the communication method, maximum transmit power used by a terminal device to send a message corresponding to a main network protocol in a semi-persistent power sharing mode is maximum transmit power 2, maximum transmit power used by the terminal device to send a message corresponding to a secondary network protocol is maximum transmit power 3, the maximum transmit power 2 is less than theoretical maximum transmit power corresponding to the main network protocol, and the maximum transmit power 3 is greater than the theoretical maximum transmit power corresponding to the main network protocol.

Abstract: The present disclosure relates to channel conflict processing methods and apparatus. In one example method, when a terminal device establishes a connection relationship with a source cell, and sends a connection request to or establishes a connection relationship with a target cell, the terminal device detects whether an uplink channel conflict occurs on an uplink channel of the source cell and an uplink channel of the target cell, where the source cell and the target cell are infra-frequency or intra-band contiguous inter-frequency. If the terminal device determines that an uplink channel conflict occurs, the terminal device sends a signal on an uplink channel with a higher priority between the uplink channel of the source cell and the uplink channel of the target cell.

Abstract: A polar code segment encoding method and a related apparatus are disclosed, and the method includes: determining, based on an information bit quantity of a first information bit sequence and a first code rate, a target code length for polar code encoding; determining an initial code length based on the target code length, where the initial code length is an integer multiple of a smallest segment code length; dividing the first information bit sequence into S segments of information bit sequences based on the first code rate and the initial code length and when the initial code length is different from the target code length, performing rate matching on the S segments in a process of performing polar code encoding on the S segments of information bit sequences, where a sum of segment code lengths of the S segments is the target code length after the rate matching.

Abstract: This application provides a data transmission method and a terminal device, to reduce a data transmission latency and improve data transmission reliability. The method includes: obtaining, by a terminal device, a grant-free GF resource configured by a base station; obtaining, by the terminal device, current channel quality; and if the current channel quality is first channel quality, transmitting, by the terminal device, to-be-transmitted data by using the GF resource, or transmitting, by the terminal device, the to-be-transmitted data by using a GB resource, where the first channel quality falls within a first range; or if the current channel quality is second channel quality, skipping, by the terminal device, transmitting to-be-transmitted data by using the GF resource, where the second channel quality falls within a second range; where the first channel quality is better than the second channel quality, and the first range is different from the second range.
