Abstract: This application provides example antenna panel status indication methods and apparatuses. One example method includes sending first antenna panel status information, where the first antenna panel status information indicates a status of at least one antenna panel. Response information of the first antenna panel status information can then be received. It can then be determined, based on the response information, that the status of the at least one antenna panel takes effect.

Abstract: This application provides a link failure recovery method and apparatus. When a link failure occurs and link recovery is performed, if a terminal device determines that no new link is identified, according to the method, the terminal device may report, to a network device, an identifier of a cell in which the link failure occurs and information indicating whether a new link is identified for each cell. The network device may reconfigure a new resource set based on the information, and notify the terminal device of the new resource set by using downlink control information DCI. In other words, a reference signal in another resource set is triggered by using the DCI, and the reference signal in the resource set is reported for link recovery.

Abstract: The present disclosure relates to resource indication methods and apparatus. In one example method, a network device configures resource configuration information for a terminal device. The terminal device determines channel state information based on the resource configuration information, and sends the channel state information. The resource configuration information is used to indicate a first reference signal resource set, L second reference signal resource sets, and a type of the first reference signal resource set. The first reference signal resource set includes resources for M first reference signals, and a resource for one of the M first reference signals is used to measure a channel.

Abstract: Example signal sending methods and apparatus are described. One example method includes obtaining a first insertion loss corresponding to a first resource and a second insertion loss corresponding to a second resource, where the first insertion loss is different from the second insertion loss. A first transmit power corresponding to the first resource is determined based on the first insertion loss. A second transmit power corresponding to the second resource is determined based on the second insertion loss. A first signal is sent on the first resource based on the first transmit power. A second signal is sent on the second resource based on the second transmit power.

Abstract: This disclosure provides example wireless communication methods and communication apparatuses. One example method includes that a network device sends indication information of m first symbol groups used for repeated transmission of a first transport block (TB) to a terminal. The terminal and the network device determine, according to a same rule, a quasi co-location (QCL) assumption corresponding to each of second symbol groups actually used when the first TB is sent or received.

Abstract: Devices, methods and computer readable medium for two-part feedback information transmission in wireless communications are provided. The two-part feedback information transmission is adopted, e.g., for improved downlink multiple-input and multiple-output (MIMO) precoding in time-division duplex (TDD)-based communication systems. The feedback information transmission allows compensating for adverse effects of incomplete UL-DL reciprocity for DL MIMO precoding caused by mismatched DL and UL channel measurements. The feedback information transmission being two-part allows low overhead for the feedback information.

Abstract: This application provides a link failure recovery method and apparatus. A terminal is configured to send first request information to a network device on the same resource (namely, a first resource) when detecting that a link of any one of a plurality of cells fails or the links of more than one of the plurality of cells fail, to notify the network device that a link of at least one of the cells fails. In this way, in a multi-carrier scenario resource overheads are reduced as compared to the solution of using separate resources to notify link failures in multiple cells.

Abstract: This application discloses a sequence generating method and apparatus, and relates to the field of communications technologies, to resolve a problem that a PAPR of a DMRS symbol is higher than that of a data symbol. An initialization factor of a first sequence is obtained, where the initialization factor is associated with a first parameter; and the first sequence is generated based on the initialization factor. In addition, the first parameter is a port number, or the first parameter is a code division multiplexing CDM group identity.
