Abstract: A communication method includes a communication apparatus that determines first information indicating that N consecutive time units are configured for sending a first message in a joint transmission manner. A receiving device that receives the first message performs joint channel estimation in the N bundled consecutive time units to obtain the first message, and when there are P unavailable time units in the N consecutive time units indicated by the first information, the communication apparatus sends the first message in the joint transmission manner in M consecutive time units different from the P unavailable time units.

Abstract: A transmit end obtains a frequency hopping parameter and resource allocation information of a to-be-transmitted message, where the frequency hopping parameter includes at least one of bandwidth part indication information, beam indication information, reference signal configuration information, subcarrier spacing indication information, transmission waveform indication information, slot type indication information, channel type indication information, and transmission carrier indication information. The transmit end determines, based on the resource allocation information and the frequency hopping parameter, a physical resource used to send the to-be-transmitted message, where the physical resource includes information about a frequency domain resource on which the to-be-transmitted message is mapped in at least one time unit. The transmit end sends the to-be-transmitted message by using the physical resource.

Abstract: A communication link initialization method includes that a master node sends a first information frame to a slave node. The first information frame includes first synchronization information. The slave node implements synchronization with the master node based on the first synchronization information. The slave node sends a second information frame to the master node. The second information frame includes second synchronization information. The master node implements synchronization with the slave node based on the second synchronization information. The master node sends a third information frame to the slave node. The third information frame is used to indicate a first training information frame. The slave node trains a link between the master node and the slave node based on the third information frame. The slave node sends a fourth information frame to the master node.

Abstract: The present disclosure includes systems, devices, and methods that provide a control signaling transmission method. One example method includes: determining a resource subset used to transmit control signaling, where the resource subset is a part of a resource pool used to transmit the control signaling; and performing one of the following operations: determining a transmission location of the control signaling in the resource subset and sending the control signaling at the transmission location, or performing blind control signaling detection in the resource subset.

Abstract: Example information transmission methods, and apparatus are described. One example information transmission method includes determining resources for carrying N pieces of uplink control information (UCI) that partly overlap or completely overlap in time domain. The N pieces of UCI comprise at least one piece of beam channel quality information and at least one of a piece of channel state information or an acknowledgement (ACK)/a negative acknowledgement (NACK). A priority of the beam channel quality information is higher than a priority of the channel state information. A priority of the beam channel quality information is lower than a priority of the ACK/NACK.

Abstract: Example hybrid automatic repeat request (HARQ) feedback methods and apparatus are provided. One example method includes a network device obtains first indication information used to instruct a terminal device to feed back HARQ feedback information. The first indication information is obtained based on information amounts corresponding to a data channel and/or information amounts corresponding to a control channel that are in a reference slot and at least one first slot. The reference slot and the at least one first slot each correspond to a different component carrier of a plurality of component carriers serving the terminal. The reference slot and the at least one first slot have a same start moment, and at least two of the plurality of component carriers have different slot lengths. The network device sends, to the terminal device, indication information used to indicate at least the first indication information.
