EFFICIENT SRS RESOURCE INDICATION METHODS
First Claim
1. A method in a wireless device, operable in a wireless communication network, of identifying reference signal resources to be used in a transmission by the wireless device, the method comprising:
- receiving signaling configuring the wireless device with a plurality of reference signal resource groups, each group comprising a plurality of reference signal resources;
receiving an indication, in a control channel, of a selection of reference signal resources to be used, wherein each of the plurality of reference signal resources to be used is selected from a different one of the plurality of reference signal resource groups such that reference signal resources belonging to the same reference signal resource group are not selected for simultaneous use; and
transmitting a reference signal to a network node in the network using the indicated selection of reference signal resources.

Abstract
A method of identifying reference signal resources to be used in a transmission by a wireless device is disclosed. The method comprises a wireless device receiving signaling configuring the wireless device with a plurality of reference signal resource groups, each group comprising a plurality of reference signal resources. The wireless device subsequently receives an indication, in a control channel, of a selection of reference signal resources to be used. Each of the plurality of reference signal resources to be used is selected from a different one of the plurality of reference signal resource groups such that reference signal resources belonging to the same reference signal resource group are not selected for simultaneous use. A reference signal is then transmitted to a network node in the network using the indicated selection of reference signal resources.
