Abstract:
Technology for a user equipment (UE) using a self-contained scheduling resource to communicate with an eNodeB within a wireless communication network is disclosed. The UE can select, at the UE, a selected eNodeB transmission (Tx) beam and a selected UE reception (Rx) beam based on a highest power beamforming reference signal (BRS) received power (BRS-RP). The UE can signal a transceiver of the UE to transmit to the eNodeB a scheduling request (SR), using the selected Rx beam, on a scheduling request (SR) resource in a self-contained subframe according to a time and frequency location of the selected eNodeB Tx beam. The UE can process an advanced physical downlink control channel (xPDCCH), received from the eNodeB, for an uplink (UL) grant using the selected UE RX beam.
