Abstract

Mechanisms are disclosed for scheduling uplink transmissions of a plurality of user equipment devices, UEs, served by a network node having a coverage area comprising a plurality of sectors. A plurality of schedulers are started in parallel, each scheduler corresponding to a different sector of the plurality of sectors. Each scheduler schedules at least some UEs associated with corresponding different sectors in parallel.

Description

technical field [0001] The present disclosure relates generally to communication systems, and more particularly to parallel scheduling of devices for transmission in a cellular communication system. Background technique [0002] A base station has a limited number of resource units, such as scheduling blocks, that can be allocated for uplink transmissions by user equipment devices (UEs) in the coverage area of ​​the base station. The effective number of available scheduling blocks can be increased by deploying multiple antennas to spatially divide the service area into sectors. Spatial separation of UE devices in different sectors frequently allows the base station to schedule different UEs in different sectors to use the same scheduling block for uplink transmission without worrying about interference. For example, where scheduling blocks are defined in terms of frequency, two UE devices that are sufficiently spatially separated in two different sectors can be assigned the...
