Abstract

The invention provides a scheduling request method and a terminal device. The method comprises the steps that the terminal device determines that a condition of triggering an SR (scheduling request) of a first service is met; the terminal device determines whether a priority of the first service is higher than a priority of a second service, wherein the SR of the second service is triggered or sent; and if the terminal device determines that the priority of the first service is higher than the priority of the second service, the terminal device triggers and / or sends the SR of the first service. Through adoption of the scheduling request method, the SR triggered or sent by the first service with higher priority is not affected by the SR triggered or sent by the second service with lower priority according to the priorities of the services, so that the opportunities for triggering or sending the SR of the first service are increased, the SR triggered or sent by the first service is morereliable, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of communications, and more specifically, to a method for scheduling requests and a terminal device in the field of communications. Background technique [0002] In a long term evolution (long term evolution, LTE) system, a scheduling request (scheduling request, SR) is a way for a user equipment (User Equipment, UE) to apply for resources from a network device for new data transmission. If the UE in the connected state has no uplink authorization and has SR resources, it sends SR first, requesting to allocate a small amount of resources. The SR belongs to the information of the physical layer. The action of sending the SR by the UE itself does not require radio bearer (radio bearer, RB) resources, and can be transmitted through the physical uplink control channel (physical uplink control channel, PUCCH). After the network device successfully decodes the SR signal of a certain UE, it may allocate RB resourc...
