Abstract: A communication method and an apparatus are provided. The method includes: receiving, by a terminal device, a first command sent by a network device, wherein the first command carries a first identifier, and is used to activate a first bandwidth part (BWP) indicated by the first identifier, and the first BWP is a BWP on a first component carrier (CC); and ignoring the first command when the terminal device does not support the first BWP and a second BWP being in an active state at the same time, wherein the second BWP is a BWP in the active state on a second CC, and the second CC is different from the first CC. According to the application, the terminal device may determine, based on a capability of the terminal device, to ignore an improper command, to optimize a problem of switching an active BWP in a carrier aggregation scenario.

Abstract: A scheduling request triggering method, apparatus, and system are disclosed. The method includes: obtaining, by a terminal device, an uplink semi-persistent scheduling resource allocated by a base station, where the uplink semi-persistent scheduling resource is used to transmit to-be-transmitted data on a logical channel of the terminal device; receiving, by the terminal device, scheduling request masking set by the base station for a first logical channel; and after determining that a triggering condition is satisfied, triggering, by the terminal device, a scheduling request via the first logical channel. In this way, when a status of data of the terminal device changes, an appropriate scheduling resource can be obtained, so as to ensure timely data transmission.

Abstract: The present disclosure is directed to a D2D data transfer method, and user equipment and a network device that use the method. In one method, user equipment determines a logical channel used for to-be-transmitted Device to Device (D2D) data. The user equipment determines a logical channel group corresponding to the logical channel. The user equipment reports, to a network device, a D2D data volume of the logical channel group for the user equipment. The user equipment sends, on a D2D resource that is allocated by the network device to the user equipment according to the D2D data volume, the to-be-transmitted D2D data to another user equipment by using the determined logical channel.
