Abstract

Exemplary embodiments include methods performed by a radio access network node for power control of UE uplink (UL) transmissions that are associated with data services having different reliability requirements. Such methods include configuring the UE with a plurality of resources that can be allocated for UL transmissions based on one or more transmit power control (TPC) parameters. The resources include first resources associated with first parameter values and second resources associated with second parameter values, for the respective TPC parameters. The first parameter values provide increased UL transmission reliability versus the second parameter values. Such methods include transmitting, to a UE, a downlink control message comprising an indication that the first resources or the second resources are allocated for an UL transmission associated with a data service, and an indication of the first parameter values or the second parameter values to be used for power control of the UL transmission.

Description

technical field [0001] The present invention relates generally to wireless communication networks and, in particular, to improvements in power control for uplink transmissions. Background technique [0002] Generally, all terms used herein will be interpreted according to their ordinary meanings in the relevant technical field, unless a different meaning is explicitly given and / or a different meaning is implied in the context in which it is used. Unless expressly stated otherwise, all references to an element, means, component, means, step, etc. are to be construed openly as referring to at least one instance of the element, means, component, means, step, etc. The steps of any method disclosed herein do not have to be performed in the exact order disclosed, unless a step is explicitly described as being after or before another step and / or it is implied that a step must be before or after another step. Any feature of any embodiment disclosed herein can be applied to any othe...
