Abstract  Abstract

The invention claims a method for transmitting and receiving SPS communication method system and device. User equipment (UE) is configured for receiving a physical downlink control channel in a first subframe or strengthening type with semi-persistent scheduling (SPS) activation corresponding to a physical downlink control channel (PDCCH/EPDCCH). PDCCH/EPDCCH transmit nSCID value. UE configures downlink based on SPS activation in the second sub-frame (DL) allocation for receiving SPS physical downlink shared channel (PDSCH) not corresponding to the PDCCH/EPDCCH. UE using the SPS activation is associated with a corresponding PDCCH/EPDCCH nSCID determining the reference signal sequence corresponding to the SPS PDSCH. UE receives SPS PDSCH in the second sub-frame. UE using the SPS activation is associated with a corresponding PDCCH/EPDCCH nSCID for SPS PDSCH in the second sub-frame of reference signal sequence processing the SPS PDSCH. UE configured for transmission mode 10 (TM10).

Methods systems and devices for transmission and reception of SPS communications are disclosed herein. User equipment (UE) is configured to receive in a first subframe a physical downlink control channel or enhanced physical downlink control channel (PDCCH/EPDCCH) corresponding to semi-persistent scheduling (SPS) activation. The PDCCH/EPDCCH conveys a value of nSCID. The UE configures based on the SPS activation a downlink (DL) assignment in a second subframe for receiving an SPS physical downlink shared channel (PDSCH) without a corresponding PDCCH/EPDCCH. The UE determines a reference signal sequence corresponding to the SPS PDSCH using nSCID derived from the PDCCH/EPDCCH corresponding to the associated SPS activation. The UE receives the SPS PDSCH in a second subframe. The UE processes the SPS PDSCH based on the reference signal sequence for the SPS PDSCH in the second subframe using the nSCID derived from the PDCCH/EPDCCH corresponding to the associated SPS activation. The UE is configured for transmission mode 10 (TM10).
