Abstract: An uplink data transmission method and an apparatus are provided. The method includes: A network device sends configuration information to a terminal device, where the configuration information is used to configure N SRS resources; the network device sends downlink control information to the terminal device, where an SRI field and a TPMI field in the downlink control information jointly indicate M SRS resources in the N SRS resources; and the terminal device sends uplink data by using the M SRS resources. M is an integer greater than or equal to 1. When M is greater than 1, multi-beam uplink transmission of the terminal device can be implemented, and coverage and a capacity of uplink transmission can be improved.

Abstract: This application provides example communication methods and example communications devices. One example method includes sending, by a terminal device, a notification message, where the notification message is used to notify a network device of information about a first radiation intensity of the terminal device when the terminal device uses at least one of a first beam or a first antenna panel. The terminal device can then send data by using at least one of a second beam or a second antenna panel, where a second radiation intensity of the terminal device when the terminal device sends the data by using the at least one of the second beam or the second antenna panel is less than the first radiation intensity of the terminal device.

Abstract: Example antenna panel management methods of a terminal device are described. One example method includes that the terminal device enters a sleep mode from an active mode. When the terminal device is ready to re-enter the active mode from the sleep mode, if sleep duration is less than a preset threshold, a single panel of the terminal device is activated. If the sleep duration is greater than or equal to the preset threshold, a plurality of panels of the terminal device are activated. The terminal device activates a panel based on sleep duration between two consecutive DRX ON modes, so that a suitable panel can be activated in time, and a suitable beam can be further found for communication with a base station.

Abstract: This application provides example signal transmission methods and communications apparatuses. One example method includes receiving first configuration information, where the first configuration information includes at least one transmission configuration indicator (TCI) state and a configuration of a tracking reference signal (TRS) of a first channel, and the TRS is a set including a plurality of channel state information reference signal (CSI-RS) resources. A quasi-colocation (QCL) parameter of the first channel is determined based on one or more of a first CSI-RS resource in a plurality of CSI-RS resources included in a first TRS in the TRS, a first TC state in the at least one TCI state, and a synchronization signal and PBCH block (SSB). The first channel is then received on the QCL parameter of the first channel.

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.
