Abstract:
1. A method for Semi-Persistent Scheduling, SPS, transmission, comprising: determining, by a User Equipment, UE, a Multimedia Broadcast multicast service Single Frequency Network, MBSFN, sub-frame; and receiving, by the UE, an SPS transmission data packet in the MBSFN sub-frame, wherein receiving by the UE an SPS transmission data packet in the MBSFN sub-frame comprises: receiving, by the UE, in the MBSFN sub-frame and decoding a data packet, borne over a Physical Downlink Shared Channel, PDSCH, transmitted over a configured downlink assignment by an evolved NodeB, eNB, and transmitting Non-Acknowledgement, NACK, information to the evolved NodeB, eNB, upon decoding in error; discarding, by the UE, the data packet transmitted by the eNB; or judging, by the UE, whether to discard the data packet, and if so, then discarding the data packet; otherwise, reserving the data packet; and receiving, by the UE, a retransmitted data packet for the data packet transmitted from the eNB and decoding it in combination with the data packet decoded in error to obtain PDSCH transmitted unicast service data.
