Radio base station and method for scheduling radio resources for user equipment

摘要

Embodiments herein relate to a method in a radio base station (12) for scheduling a radio resource to a first user equipment (10). The radio base station (12) is comprised in a radio communications network and controls a number of radio resources to be scheduled for communication to a number of user equipments (10,11). The number of user equipments comprises the first user equipment (10) and being served by the radio base station (12). The scheduling is based on channel quality of channels used by the respective user equipments. The radio base station (12) estimates a first channel quality of a channel used by the first user equipment (10). The radio base station determines a pathloss between the first user equipment (10) and the radio base station (12), and computes a second channel quality of the channel based on the estimated first channel quality and the determined pathloss. The radio base station (12) then schedules a radio resource out of the number of radio resources to the first user equipment (10) based on the second channel quality.

主权项

1. A method, in a radio base station, for scheduling a radio resource to a first user equipment (UE), the radio base station in a radio communications network and controlling a plurality of radio resources to be scheduled for communication to a plurality of UEs based on channel quality of channels used by the respective UEs, the plurality of UEs served by the radio base station and comprising the first UE, the method comprising:
estimating a first channel quality of a channel used by the first UE based on a comparison between transmitted power from the first UE and received power at the radio base station; determining a pathloss between the first UE and the radio base station, wherein the first UE is currently served by the radio base station; selectively applying pathloss compensation to the pathloss to obtain a compensated pathloss; computing a second channel quality of the channel based on the estimated first channel quality and the compensated pathloss; and scheduling a radio resource out of the plurality of radio resources to the first UE based on the computed second channel quality.
