Abstract: The method is applied to a communications system including a first network device, a second network device, and a terminal device. The terminal device is communicatively connected to the first network device and the second network device respectively. The method includes: sending, by a network device, a first message to the terminal device, where the first message is used to determine that the terminal device stops communication with the first network device, or the first message is used to determine that the terminal device releases a protocol stack and a data radio bearer that are corresponding to the first network device; and the network device is the first network device or the second network device. Therefore, power consumption of the terminal device or the first network device and waste of air interface resources can be reduced, and flexibility can effectively be improved in a communication process.

Abstract: When a PDCP entity over a UM DRB is re-established, or when a cell handover occurs and a PDCP entity over a UM DRB uses a key used before the handover, the PDCP entity determines a first SDU, where the first SDU is an SDU that is associated with a sequence number by the PDCP entity but whose corresponding data has not been transmitted through an air interface; and delivers a PDU corresponding to the first SDU to an RLC entity.

Abstract: Embodiments of this application provide a scheduling request processing method and a terminal device. The scheduling request processing method includes: determining, by a terminal device, whether there is a regular BSR associated with a first logical channel that is triggered and has not been canceled; and if a regular BSR associated with the first logical channel is triggered and has not been canceled, and the terminal device has no uplink resource available to transmit data of the first logical channel, and a first timer of the terminal device is not running, triggering, by the terminal device, an SR, where the first timer is configured to delay transmission of the SR. According to the scheduling request processing method provided in the embodiments of this application, when the terminal device has no uplink resource available to transmit the data of the logical channel associated with the BSR, the SR is triggered to implement uplink resource scheduling, thereby satisfying a QoS requirement of the data carried on the logical channel.

Abstract: A measurement signal transmission method and apparatus, and a network device are disclosed. The method includes the following steps: determining a physical resource block used to deploy a measurement signal, where the physical resource block is a subset of all physical resource blocks in frequency domain corresponding to a channel bandwidth of user equipment; determining a physical resource corresponding to the physical resource block; and transmitting the measurement signal to the user equipment by using the physical resource, where the measurement signal is used by the user equipment to measure channel information. Optionally, the method further includes: sending a resource indication message to the user equipment, where the resource indication message indicates the physical resource block occupied for deploying the measurement signal and/or the physical resource occupied for transmitting the measurement signal.

Abstract: Embodiments of the present invention provide a scheduling request sending method and a terminal device. The method includes: if data on a first logical channel of the terminal device triggers a buffer status report BSR, and the first logical channel is not configured with logical channel scheduling request prohibition, triggering a scheduling request SR in a running process of a logical channel scheduling request prohibit timer, and determining, by the terminal device, whether to send the SR. In the embodiments of the present invention, unnecessary triggering of the SR can be reduced.
