摘要： This application discloses a sidelink (SL) communication method and an apparatus. In this application, the second terminal receives first control information and first data from the first terminal, where a cast type indicated by the first control information is SL groupcast transmission with negative acknowledgement (NACK) only feedback. The second terminal starts a first timer at a specified location after a hybrid automatic repeat request (HARQ) feedback resource corresponding to the first data, where duration of the first timer indicates minimum duration that elapses before SL resource scheduling information used for HARQ retransmission is expected to be received. After the first timer expires, if the second terminal successfully decodes the first data and detects a NACK on the HARQ feedback resource, the second terminal starts a second timerwith duration indicating maximum duration that elapses before the SL resource scheduling information used for HARQ retransmission is received.

摘要： This application discloses a communication system including a master base station and a secondary base station, both connecting with a terminal. In the communication system, the master base station sends a first message to the secondary base station for allocating transmission resources for one or more flows to be transmitted between the secondary base station and a terminal, wherein the first message carries one or both of: identification information of each flow to be transmitted, and information of a data radio bearer (DRB) associated with each flow to be transmitted, then the secondary base station may determine a mapping relationship between a DRB and an admitted flow according to the first message. Moreover, the master base station sends DRB configuration information to the terminal. Therefore, requirements of 5G communication systems for QoS management of information transmission in a dual connectivity scenario can be met.

摘要： This application provides a failure processing method, a handover method, a terminal device, and a network device, to provide a manner in which a terminal receives an RRC configuration of a secondary network device and feeds back an RRC configuration failure. The method includes: directly receiving, by a terminal device, a first RRC configuration of a secondary network device from the secondary network device; and when the first RRC configuration fails, sending, by the terminal device, first indication information to a primary network device to indicate that the first RRC configuration fails. In addition, when the first RRC configuration fails, the terminal reports one piece of first indication information to the primary network device to indicate that the first RRC configuration fails.

摘要： Example communication methods and apparatus are described. One example communication method includes receiving indication information by a terminal device from a network device, where the indication information is used to indicate resource configuration information of a first uplink carrier and/or a second uplink carrier. The first uplink carrier and the second uplink carrier are different uplink carriers in a cell of the network device, and the first uplink carrier and the second uplink carrier are corresponding to one downlink carrier in the cell. The terminal device determines one uplink carrier from the at least one uplink carrier as a target carrier for performing random access based on the resource configuration information of the at least one uplink carrier.
