摘要： This application provides a radio resource control (RRC) message sending method and an apparatus. According to the method, a distributed unit (DU) determines not to start an RLC polling mechanism when sending an RRC message to a terminal device, so that when sending the RRC message to UE, the DU sets a polling bit in a header of an RLC PDU carrying the RRC message to be in an inactive state. Therefore, after receiving the RRC message, the terminal device does not feed back an RLC status report to the DU. Therefore, the terminal device does not need to initiate a random access procedure to obtain an uplink transmission resource for sending the RLC status report to the DU, thereby saving random access resources.

摘要： A method for determining a feedback resource in a sidelink includes a first terminal sending SCI to a second terminal, where the SCI includes indication information. The indication information is used to indicate a first resource or a first resource window to be occupied for sending hybrid automatic repeat request HARQ feedback information by the second terminal, and the first resource window includes a plurality of candidate first resources. The method further includes the first terminal receiving, on the first resource, the HARQ feedback information sent by the second terminal, or monitors, in the first resource window, the HARQ feedback information sent by the second terminal.

摘要： Embodiments of this application provide a scheduling request processing method and a terminal device. The scheduling request processing method includes: determining that a regular buffer status report, BSR, associated with a first logical channel is triggered and has not been canceled; determining that there is no uplink resource available to transmit data of the first logical channel, and a first timer of a terminal device is not running; and triggering a scheduling request, SR, wherein the first timer is configured to delay transmission of the SR.

摘要： A data processing method, a terminal device, and a base station are disclosed. The method includes: determining to change a type of at least one radio bearer of the terminal device from a first type to a second type; discarding a radio link control protocol RLC protocol data unit and/or an RLC service data unit buffered by a transmit side of an RLC layer entity of the at least one radio bearer; and assembling an RLC protocol data unit received by a receive side of the RLC layer entity of the at least one radio bearer into an RLC service data unit, and delivering the RLC service data unit in sequence to an upper layer entity of the RLC layer entity, where the upper layer entity is an upper layer entity of the RLC layer entity before the type of the at least one radio bearer is changed.

摘要： A method and/or a communications apparatus controls a monitoring of a physical downlink control channel. The method includes: receiving, by a terminal device, a first message sent by a network device, where the first message includes M sleep time sets, and the sleep time is used to indicate a time length in which monitoring the PDCCH is stopped; receiving, by the terminal device, a second message sent by the network device, where the second message includes sleep time indication information, the sleep time indication information is used to indicate a target sleep time index, and the target sleep time index is an index in the M sleep time sets; and stopping, by the terminal device, monitoring the PDCCH in a target time period.

摘要： A method includes that a first terminal device sends a sidelink discontinuous reception (DRX) parameter of a second terminal device or indication information to a network device such that the network device determines a first time period based on the sidelink DRX parameter or the indication information, where the first time period belongs to sidelink DRX active time of the second terminal device. The first terminal device receives a sidelink grant sent by the network device, where the sidelink grant is used to indicate the first terminal device to send a resource of a physical sidelink control channel (PSCCH) and/or a physical sidelink shared channel (PSSCH), and a time domain position of the resource is in the first time period. The first terminal device sends a PSCCH and/or a PSSCH based on the sidelink grant.
