Abstract

Embodiments of the present invention provide a resource request method and user equipment, which relate to the field of communication technology and are used to solve the problem in the prior art that the failure probability of an SR process increases due to SR transmission failure caused by LBT. The method includes: obtaining first information when the UE triggers a scheduling request SR; and performing any one of the following actions by the UE according to the first information: at least one of not increasing the count of the first counter and increasing the count of the second counter Item, at least one of the stop timer and the prohibition of starting the timer; wherein, the above-mentioned first information is used to indicate that the UE currently stops sending SR; within the duration corresponding to the above-mentioned timer, the UE cannot send SR on the SR resource; The above-mentioned first counter is used to record the number of times the SR is sent; the above-mentioned second counter is used to record the number of times the SR is stopped from being sent.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a resource request method and user equipment. Background technique [0002] At present, for unlicensed frequency bands, before sending signals, the sending end device needs to monitor whether the unlicensed frequency band is occupied. Only when the unlicensed frequency band is not occupied, the sending end device can send signals. Yes, the above listening process is called Listen-Before-Talk (LBT). [0003] In the prior art, when a user equipment (User Equipment, UE) triggers a buffer status report (BufferStatus Report, BSR) report, if there is no uplink resource to send the BSR, the UE will trigger a scheduling request (Scheduling Request, SR) to send (For example, the medium access control (Medium Access Control, MAC) layer of the UE instructs the physical (PHY) layer to send the SR). [0004] However, after the UE triggers the SR transmission, it will perfor...
