Abstract: This application discloses a data sending method, a data receiving method, and an apparatus. The data sending method includes: if first type data is punctured, preserving, by a network device, a punctured first data subset in the first type data and puncture location information of the first data subset in the first type data, and retransmitting the first data subset within a second scheduling period to a user equipment. In this way, the network device does not need to wait for feedback from the user equipment before the network device can perform a retransmission operation, so that latency of retransmission is reduced. In addition, the network device only needs to retransmit the punctured first data subset within the second scheduling period but does not need to retransmit the entire first type data, so that an amount of data to be retransmitted is reduced and fewer transmission resources are consumed.

Abstract: A communication method and apparatus to enable uplink transmission of a terminal to be synchronized with a plurality of stations corresponding to one cell, and avoid a performance loss of uplink transmission. The terminal receives configuration information from a network device, wherein the configuration information includes two timing advance groups (TAGs) corresponding to one cell, and each TAG corresponds to one timing advance (TA). The terminal receives a plurality of random access response messages from the network device, wherein each random access response message is usable to indicate a TA corresponding to one of the two TAGs.

Abstract: A cell handover method and an apparatus. Indication information is received from a source cell, where the indication information indicates to a first transmission configuration indicator TCI state and cell handover; initiating random access to a target cell according to the indication information. In response to first response information returned by the target cell being received, second response information is returned to the source cell, where the second response information indicates that the first TCI state is successfully activated. Cell handover is implemented through beam switch to reduce a delay of a terminal device during the cell handover. The terminal device returns the second response information to the source cell only after receiving the first response information returned by the target cell.

Abstract: Example reference signal measurement methods, example resource indication methods, and example apparatuses are provided. One example method includes receiving at least one reference signal from a network device. Channel state information can then be determined based on some or all of the at least one reference signal. The channel state information can then be reported to the network device based on first duration. When it is determined to activate a first antenna panel and measure the at least one reference signal by using the first antenna panel, the first duration can be determined based on a first constraint relationship. The first antenna panel can be currently not activated.

Abstract: A method and an apparatus for determining a status of an antenna panel. A terminal receives configuration information including at least one downlink signal resource set. When determining that a first antenna panel corresponding to a first downlink signal resource set is turned on, the terminal measures quality of a resource in the first downlink signal resource set by using the first antenna panel, and sends first feedback information. The first feedback information may indicate the quality of the resource in the first downlink signal resource set. When the first antenna panel is turned off, the terminal skips measuring the quality of the resource in the first downlink signal resource set, and sends second feedback information. The second feedback information is used to indicate that the first antenna panel is turned off.
