Abstract: Embodiments of the present invention provide a communication method for a carrier aggregation system. The communication method includes receiving physical downlink share channel PDSCH information sent by a base station through a subframe n of a secondary cell. If a subframe n of a primary cell is a downlink subframe, an ACK/NACK of the sent PDSCH information is fed back on a subframe m or a subframe p of the primary cell.

Abstract: This application provides a transmission indication method and a communication apparatus. The method includes: A terminal device receives a medium access control-control element MAC CE or downlink control information DCI. The terminal device does not receive any downlink transmission in one time window based on indication information in the MAC CE or the DCI. According to the solution provided in this application, discontinuous reception DRX transmission can be dynamically and flexibly configured for the terminal device. This helps reduce a performance loss of the terminal device.

Abstract: A channel state information feedback method and a communication apparatus. A network device sends reference signal configuration information to a terminal device, where the reference signal configuration information is usable for configuring N_1 reference signals, and the N_1 reference signals correspond to N antenna ports. The terminal device determines K_1 first channel vectors based on K_1 combination matrices and measurement results of the N_1 reference signals on the N antenna ports, where an ith combination matrix in the K_1 combination matrices is usable for combining the N antenna ports into M_i antenna ports; the terminal device further obtains K_1 pieces of channel state information CSI based on the K_1 first channel vectors. Then, the terminal device sends K_2 pieces of CSI in the K_1 pieces of CSI to the network device.

Abstract: A communication method and apparatus. for indicating indicate A terminal is indicated to perform second transmission when an SSB or a PRACH on a frequency domain resource overlaps with reverse transmission on another frequency domain resource in time domain. In response to the SSB or the PRACH overlapping with the second transmission in time domain, the terminal device determines, by receiving first indication information, that a priority of the SSB or the PRACH is lower than a priority of the second transmission on an overlapped time domain resource. The terminal device performs the second transmission based on the first indication information. The terminal device performs reverse transmission on a symbol that overlaps with the SSB or the PRACH.

Abstract: A wireless communication method, a communication apparatus, and a communication system. A terminal determines, based on a detected SSB, a set corresponding to the SSB, and further determines resource multiplexing manners of a plurality of SSBs in the set. Because the resource multiplexing manners of the plurality of SSBs in the set are able to be flexibly configured, adaptation to various TDD configurations are able to be implemented. In response to downlink resources in a TDD configuration being insufficient, the plurality of SSBs in the set are sent in a frequency division multiplexing manner as much as possible. In response to the downlink resources in the TDD configuration being sufficient, the plurality of SSBs in the set are sent in a time division multiplexing manner or a frequency division multiplexing manner.

Abstract: Embodiments of this application provide a wireless communication method, a communication apparatus, and a communication system. In the method, a terminal determines, based on a detected SSB, a first index of the SSB in a first set and a second index of the SSB, and then determines a resource of the SSB. One SSB may correspond to one or more resources, and time division multiplexing may be performed between different resources. Therefore, there is a plurality of sending occasions for one SSB. Each SSB corresponds to one transmit beam direction, so that a sending occasion of an SSB corresponding to a transmit beam direction may be flexibly adjusted. When a plurality of SSBs in one set are sent, a sending sequence of SSBs corresponding to different transmit beam directions may be determined according to a service requirement, to further determine a resource occupied by each SSB.
