Problems solved by technology

[0003] Antenna branch unbalance or unbalance may occur due to different feeder attenuation, different filters or unequal number of filters in different antenna branches
Additionally, failures in the antenna branches or changes in the radio environment can cause antenna branch imbalances
[0004] Changes in the balance of the antenna branches can affect the ability of the RBS to receive uplink transmissions, which can lead to dropped calls or inefficient use of uplink resources, degraded quality experienced by the user of the UE or mobile phone

Abstract

An RBS and a method performed by an RBS for scheduling uplink resources to at least one UEare provided. The RBS comprises at least two receiving antenna branches and the RBS is operable in aradiocommunication network.The method comprises receiving (110) transmissions from the at least one UE by means of the at least two receiving antenna branches; and determining (120) at least one parameter relating tosignal quality of the received transmissions. The method further comprises determining (130) a diversity gain of the at least two receiving antenna branches, wherein the diversity gain is determined based on the determined parameter(s); and scheduling (140) uplink transmissions for the at least one UE based on the determined diversity gain.

Description

technical field [0001] The present disclosure relates to a radio base station, RBS, and in particular, to an RBS and methods therefor for scheduling uplink resources to at least one user equipment, UE. Background technique [0002] A RBS may have two or more receive antenna branches. These branches are usually balanced, meaning that the energy from each individual antenna branch is about the same as the energy from the other antenna branches. This is valid for both signal energy and interference energy, whereby the antenna branches of the RBS experience a similar signal-to-interference-noise ratio, SINR. [0003] Due to different feeder attenuations, different filters or unequal numbers of filters in different antenna branches, unbalanced or unbalanced antenna branches may occur. Furthermore, failures in the antenna branches or changes in the radio environment can cause the antenna branches to become unbalanced. [0004] Changes in the balance of the antenna branches can ...
