Communication method and device

Abstract

The embodiment of the invention provides a communication method. The method comprises the following steps of: if a first logic channel of a terminal device does not have the uplink resource bearing ascheduling request and the terminal device is in the first scheduling request SR state, and the terminal device maintains the state of the first scheduling request SR and / or the state of the first buffer status report BSR until the data of the first logic channel and / or the buffer status report BSR are / is sent, wherein the buffer status report (BSR) is used for indicating buffer status informationof a logic channel group including the first logic channel, and the state of the first buffer status report (BSR) indicates that the buffer status report of the terminal device is triggered by the first logic channel and is not cancelled; the first scheduling request SR state indicates that the scheduling request is triggered by the first logical channel and is not cancelled. Under the conditionthat a certain logic channel of the terminal device does not have the uplink resource carrying the scheduling request, the problem that the terminal device cannot obtain the uplink transmission resource can be supported and solved.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and more specifically, to a communication method and device. Background technique [0002] At present, a variety of air interface formats and transmission time intervals (Transmission Time Interval, TTI) are introduced in the 5G system. In order to distinguish the various air interface formats and transmission time intervals, a user equipment (User Equipment, UE) is configured with at least A scheduling request resource, and each logical channel of the UE corresponds to at least one scheduling request resource. That is, when the UE sends a scheduling request (Scheduling Request, SR) message to the network device on a specific scheduling request resource, it requests the network device on behalf of the UE to allocate an uplink resource of its own specific TTI length in a specific air interface format. [0003] However, for the multiple logical channels corresponding to the UE...
