Uplink scheduling request processing method and device

Abstract

The invention provides a method and device for processing an uplink scheduling request, belonging to the technical field of communications. The method includes: for any service corresponding to any logical channel, when the service data of any service arrives at any logical channel, determining whether the UE has been configured with uplink resources; when the UE is not configured with uplink resources, based on any service Trigger SRs. When the UE has been configured with uplink resources, if any service is a specified service, the regular BSR is triggered when the service data of the specified service arrives, and the configuration period of the uplink resource is greater than the preset threshold, the SR is triggered based on the specified service. For services with lower priority that arrive later, SR can also be triggered when the UE is not configured with uplink resources, that is, multiple SRs can be triggered regardless of the service priority, thus avoiding the SR cannot be triggered if the normal trigger conditions are met, thereby ensuring that services with lower priority can be scheduled in time.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a method and device for processing an uplink scheduling request. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, when the UE (User Equipment, user equipment) has no service data to send, that is, when there is no need to upload service data to the eNodeB (Evolved Node B, evolved base station), the eNodeB and There is no need to allocate uplink resources for the UE. Otherwise, uplink resources will be wasted. [0003] Based on the above reasons, for any logical channel corresponding to the UE, when service data arrives in the cache of the logical channel, the UE usually needs to inform the eNodeB that it has service data to send, and the eNodeB will decide whether to allocate uplink resources to the UE accordingly . Among them, the UE in RRC_CONNECTED state and maintaining uplink synchronization can send SR (Sch...

Problems solved by technology

[0008] Since there are services with different priorities in the NR system, when the services with higher priority arrive first, the service with higher priority will trigger SR, and for the services with lower priority that arrive later, the SR will be triggered because the above-mentioned conventional The BSR trigger condition cannot be triggered, so the SR will not be triggered, and the services with lower priority cannot be scheduled in time.
