摘要：Methods, systems, and devices for transmission and reception of SPS

communications are disclosed herein. User equipment (UE) is configured to receive, in afirst subframe, a physical downlink control channel or enhanced physical downlinkcontrol channel (PDCCH/EPDCCH) corresponding to semi-persistent scheduling (SPS)activation. The PDCCH/EPDCCH conveys a value of nSCID. The UE configures, based onthe SPS activation, a downlink (DL) assignment in a second subframe for receiving an SPSphysical downlink shared channel (PDSCH) without a corresponding PDCCH/EPDCCH. TheUE determines a reference signal sequence corresponding to the SPS PDSCH using nderived from the PDCCH/EPDCCH corresponding to the associated SPS activation. The UEreceives the SPS PDSCH in a second subframe. The UE processes the SPS PDSCH based onthe reference signal sequence for the SPS PDSCH in the second subframe using the nderived from the PDCCH/EPDCCH corresponding to the associated SPS activation. The UEis configured for transmission mode 10 (TM10).
