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: An access network device sends first information and second information to a terminal, where the first information includes a value set of a communication time interval, and the second information indicates a value of the communication time interval in the value set, and the value is used to determine timing duration of a hybrid automatic repeat request (HARQ) round trip time (RTT) timer. The communication time interval includes at least one of a time interval from the terminal receiving downlink scheduling grant information to the terminal receiving downlink data scheduled by using the downlink scheduling grant information, a time interval from the terminal receiving downlink data to the terminal sending HARQ feedback information of the downlink data, and a time interval from the terminal receiving uplink scheduling grant information to the terminal sending uplink data scheduled by using the uplink scheduling grant information.

Abstract: A segment retransmission method includes: if a receiving RLC function entity has not received, within a preset time period, all segments of a data packet identified by a serial number, the receiving RLC function entity sends a retransmission request to a sending party, where the retransmission request includes the serial number, to request the sending party to retransmit an unreceived segment of the data packet identified by the serial number, and thus reduces an average data packet transmission latency.

Abstract: A first terminal obtains a first transmission resource that is sent by an access network device and that is used by the first terminal to send data on a sidelink, where the sidelink is a wireless communication link between the first terminal and a second terminal, and the first transmission resource is a resource of an unlicensed spectrum. The first terminal performs a channel access procedure on the unlicensed spectrum. The first terminal sends first information to the access network device when the first terminal determines that a failure occurs in the channel access procedure performed on the unlicensed spectrum, where the first information is used to request to allocate a second transmission resource to the sidelink of the unlicensed spectrum.

Abstract: This application provides an example sidelink transmission resource configuration method. Each piece of sidelink data corresponds to one transmission requirement. After obtaining a first data, a terminal device determines a transmission feature of the first resource, and determines, depending on whether reliability of the first resource meets a reliability requirement of the first data, whether to send the first data by using the first resource.
