Abstract

The embodiment of the invention provides an uplink resource allocation method and device. The method comprises the following steps: a terminal receives one or more UL grants; and when performing uplink resource allocation on each of the UL grants, based on a mapping relation between bearer or logical channels and numerologies and / or TTI (Transmission Time interval) lengths, the terminal allocates uplink resources to the bearer or logical channels whose supportable maximum numerologies and / or TTI lengths are equal to the numerology and / or the TTI length corresponding to the UL grant and which have data in need of being transmitted. The problem that a transmission resource of a service which has a low priority but is relatively sensitive to a time delay is preempted by a service having a high priority is solved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for allocating uplink resources. Background technique [0002] 1) The LCP (Logical Channel Prioritization, logical channel priority) process of the traditional LTE (Long Term Evolution, long-term evolution) system [0003] The LCP of the LTE system is performed based on the priority parameter priority corresponding to a single RB (Radio Bearer, radio bearer) configured by the network. The specific implementation process is as follows: [0004] Step 1: Perform the first round of resource allocation in descending order of priority parameters of all logical channels with tokens. The first round of resource allocation is performed based on the PBR (Prioritized Bit Rate, prioritized bit rate) of each logical channel. At the same time, the number of tokens available for each logical channel is updated according to the allocation of uplink resources...
