Abstract: A communication method is provided. In the method, if a first logical channel of a terminal device does not have an uplink resource for carrying a scheduling request (SR) and the terminal device is in a first SR state, remaining, by the terminal device, in the first SR state and/or a first buffer status report (BSR) state until data of the first logical channel and/or a BSR are/is sent, where the BSR is used to indicate buffer status information of a logical channel group including the first logical channel. When a logical channel of the terminal device does not have an uplink resource for carrying the scheduling request, a problem that the terminal device cannot obtain an uplink transmission resource can be resolved.

Abstract: Embodiments of this application provide a communication method and apparatus, and a computer storage medium, to reduce communication latency between a terminal and a base station, and improve a capability of adapting to a latency-sensitive scenario. The method provided in this application includes a terminal that receives at least one uplink configuration and at least one random access configuration from a network device. The uplink configuration is used to indicate a parameter for sending uplink data, and the random access configuration is used to indicate a parameter for sending a preamble. The at least one uplink configuration includes a first uplink configuration, the at least one random access configuration includes a first random access configuration, and there is a correspondence between the first uplink configuration and the first random access configuration.

Abstract: A discontinuous reception communication method and communications apparatus, a communications device, and a communications system are provided. The communications device is configured to: receive, during running of a timer T11, indication information sent by a network device, where the indication information includes HARQ feedback information for initial transmission or retransmission of data of a terminal device, and the timer T11 is started after the initial transmission or the retransmission of the data and is used to monitor a physical downlink control channel PDCCH; and stop the timer T11. Because the timer is stopped immediately when the HARQ feedback information for the data is received, the terminal device is allowed to enter a sleep state. In this way, duration in which the terminal device is in an active state can be shortened, and power consumption can be reduced.

Abstract: This application provides a communication method, a communications apparatus and a non-transitory computer-readable medium. A network device receives data carried on a first scheduling-free resource via a first hybrid automatic repeat request (HARQ) process from a terminal device, and decodes the data to generate HARQ feedback information. The network device sends downlink control information (DCI) to the terminal device, where the DCI includes the HARQ feedback information and first indication information. The first indication information indicates the first HARQ process.

Abstract: A communication method includes determining, by a terminal side device, that a consistent uplink listen before talk (LBT) failure occurs in a first bandwidth part (BWP) of a cell. The communication method also includes canceling, by the terminal side device, a consistent uplink LBT failure status of the cell in response to a determination by the terminal side device to switch to a second BWP of the cell.

Abstract: This application provides a random access method and apparatus. The method includes: A terminal device receives first information sent by a network device, where the first information includes a priority value of a first parameter used for a random access procedure. The terminal device initiates the random access procedure based on the priority value. In this way, the terminal device can preferentially select, based on the priority value of the first parameter, a two-step random access procedure or send a message in the random access procedure by using high power, to quickly access a network and reduce an access delay.

Abstract: A data transmission method and an apparatus, in which the method includes: receiving first indication information sent by a network device, where the first indication information includes identifier information of a first HARQ process and information about a first resource; sending first data of the first HARQ process on the first resource based on the first indication information; sending data of the first HARQ process based on an instruction of the network device within a preset time after the first data is sent; and sending data of the first HARQ process on a second resource after the preset time ends, where the second resource is used for scheduling-free transmission. Therefore, after a terminal device performs scheduling transmission, a HARQ process can be prevented from being blocked, so that the terminal device can continue to perform scheduling-free transmission.

Abstract: Embodiments of the present disclosure provide a method of interworking between networks and a device. A network device sends an indication message to UE, where the indication message is used to indicate whether the UE is allowed to perform RAN rule-based LTE-WLAN interworking in an idle mode, so that the UE can determine, according to an indication of a network side, whether to perform the RAN rule-based LTE-WLAN interworking in an idle mode, and the network side can accurately control LTE-WLAN interworking for the UE in an idle mode.

Abstract: A communication method and a related apparatus. The method includes: a terminal device receives first indication information sent by a network device. When the first indication information indicates a channel unoccupied time of the network device, within the channel unoccupied time, the terminal device skips performing downlink measurement, skips receiving the downlink data, skips sending a HARQ feedback corresponding to the downlink data, or determines that a downlink measurement result is invalid. Unnecessary measurement can be reduced, a downlink measurement failure caused because a network side does not preempt a channel can be excluded, and measurement efficiency and accuracy of a measurement result can be improved.
