Abstract: This application provides a communication method and apparatus. The method includes: A terminal device receives indication information from a master node, where the indication information indicates that a key used for signaling transmission performed between the terminal device and a first secondary node by using a second SRB is a first key, the first key is a key used for signaling transmission performed between the terminal device and the master node by using a first SRB, and the first secondary node and the master node share one CU. In a scenario in which the master node and a secondary node share one CU, the terminal device determines that a key for signaling transmission performed between the terminal device and the secondary node is the same as a key for signaling transmission performed between the terminal device and the master node, which avoids complexity.

Abstract: Example measurement methods and apparatus are described. One example method includes obtaining a timer by a terminal device. The terminal device obtains two or more measurement configurations, where each of two or more measurement configurations includes a validity area and a measurement frequency corresponding to the validity area, and the validity area includes one or more cells. The terminal device measures, based on the measurement configuration, a measurement frequency corresponding to a validity area that matches a cell on which the terminal device camps, where the terminal device is in an idle state or in an inactive state, and the timer is not stopped and has not expired.

Abstract: This application provides a communication method and apparatus. The communication method includes: receiving measurement configuration information from a network device; determining whether a measurement task requires a measurement gap; and if the measurement task does not require the measurement gap, sending first measurement gap requirement information indicating that the measurement gap is not required to the network device, where the first measurement gap requirement information is used to deactivate or release configured measurement gap configuration information; and/or if the measurement task requires the measurement gap, sending second measurement gap requirement information indicating that the measurement gap is required to the network device, where the second measurement gap requirement information is used to activate or validate measurement gap configuration information corresponding to the second measurement gap requirement information. A measurement gap configuration status is determined based on measurement gap requirement information reported by a terminal device.

Abstract: This application provides a communication method and apparatus, to determine a DRX cycle. The method includes: receiving data in an active time of a current DRX cycle; when a DRX inactivity timer of the current DRX cycle expires, determining a type of a next DRX cycle depending on whether at least some data received in the active time is associated with a DRX short cycle, where if the at least some data is not associated with a DRX short cycle, the next DRX cycle is a DRX long cycle, or the type of the next DRX cycle is the same as that of a DRX cycle previous to the current DRX cycle. When the DRX inactivity timer expires, the type of the next DRX cycle can be more flexibly determined, and may not necessarily be a DRX short cycle. This can save power of a device to some extent.

Abstract: This disclosure discloses methods, apparatuses, and systems for performing handover. One method comprises: receiving, by a target access network device after a mapping relationship between a quality of service (QoS) flow of a terminal device and a data radio bearer (DRB) changes, a handover request from a source access network device, wherein the handover request comprises indication information for requesting to establish a tunnel; and sending, by the target access network device to the source access network device, information about the tunnel for the target access network device to receive one or more data units from the source access network device after the mapping relationship between the QoS flow and the DRB changes.

Abstract: Example communication methods and apparatus are described. One example communication method includes receiving broadcast information by a terminal device. The broadcast information includes a first parameter and a second parameter that are for a first cell. The first parameter is used for cell selection or cell reselection performed by a terminal device that supports supplementary uplink (SUL) carrier transmission, and the second parameter is used for cell selection or cell reselection performed by a terminal device that does not support SUL carrier transmission. The terminal device performs cell selection or cell reselection based on the first parameter when the terminal device supports SUL carrier transmission. The terminal device performs cell selection or cell reselection based on the second parameter when the terminal device does not support SUL carrier transmission.

Abstract: A base station configures, for a terminal, a contention-free random access resource for a beam failure recovery request. After determining that a beam failure has occurred, the terminal performs random access, and retains the contention-free random access resource after the random access succeeds, so that a beam failure recovery latency and signaling overheads can be reduced.

Abstract: The application discloses a data transmission method, including: receiving, by UE, first indication information from a wireless access device, where the first indication information is activation indication information or deactivation indication information; and when the first indication information is the activation indication information, executing, by the UE, a processing operation; or when the first indication information is the deactivation indication information, stopping, by the UE, the processing operation; where the processing operation includes at least one of a duplication operation and a switching operation; the duplication operation means transmitting same data through a plurality of links; and the switching operation means selecting one from a plurality of links to perform data transmission. According to the foregoing method, reliability of the data transmission can be improved, and when no processing operation needs to be executed, additional resource overheads caused by data transmission performed through the processing operation can be reduced.
