METHODS AND NODES FOR MULTIPLE USER MIMO SCHEDULING AND POWER CONTROL

摘要

The present invention relates to a method in a first User Equipment (UE) served by a radio base station (RBS) of a wireless network, for uplink power control at Multiple User Multiple-Input-Multiple-Output (MU-MIMO) scheduling. The method comprises obtaining a power adaptation parameter for use in uplink transmission power control when the first UE is scheduled to be in pair with a second UE, or is scheduled to be de-paired from the second UE. The method also comprises receiving an indication from the radio base station to use the obtained power adaptation parameter in uplink transmission power control, and adapting an uplink transmission power based on the obtained power adaptation parameter and the received indication. The present invention also relates to the corresponding method in the RBS, and to the UE and the RBS.

1. A method in a radio base station of a wireless network, for supporting uplink power control when performing Multiple User Multiple-Input-Multiple-Output scheduling, the method comprising when scheduling a first user equipment (UE) in pair with a second UE, or scheduling the first UE de-paired from the second UE:
transmitting an indication to the first UE to use a power adaptation parameter for uplink transmission power control, wherein the power adaptation parameter enables the first UE to adapt an uplink transmission power to an interference change due to pairing or de-pairing with the second UE.
