    摘要： 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.

    摘要： There is provided mechanisms for beamforming of beams. A method is performed by a radio transceiver device. The method comprises performing beamforming by switching between communicating in a first set of beam patterns and in a second set of beam patterns. The first set of beam patterns and the second set of beam patterns comprise equally many beams. Signals in the beams are communicated with a first set of other radio transceiver devices in the first set of beam patterns and with a second set of other radio transceiver devices in the second set of beam patterns. The first set of other radio transceiver devices and the second set of other radio transceiver devices at least partly overlap.
