Abstract (en)
[origin: WO2016077975A1] An Evolved Node-B (eNB) configured to support group sounding at a multiple-input multiple-output (MIMO) antenna array. The eNB may include hardware processing circuitry configured to transmit, for reception at multiple User Equipments (UEs), a physical downlink control channel (PDCCH) data block that includes a masked group SRS request. The hardware processing circuitry configured to receive a group SRS that includes a sum of an SRS from each of the multiple UEs during a group SRS transmission period and in group SRS frequency resources. The hardware processing circuitry may include one or more transceivers configured to be coupled to a multiple-input multiple-output (MIMO) antenna array that includes a grid of multiple antenna elements and the reception of the SRS from each of the multiple UEs may be performed at the MIMO antenna array.
