Abstract:
1. A method of controlling a scheduling scheme, the method performed by a base station (BS) and comprising: transmitting first scheduling information including a first resource assignment and a first new data indicator (NDI) on a physical downlink control channel (PDCCH) to a user equipment (UE) to activate a semi-persistent scheduling (SPS) for a downlink data packet to be delivered to the UE with the first resource assignment, the first scheduling information being masked with a persistent Cell Radio Network Temporary Identifier (C-RNTI) associated with the SPS, the first NDI indicating a first value; and transmitting second scheduling information including a second resource assignment on the PDCCH from the BS, the second scheduling information being masked with the persistent C-RNTI associated with the SPS, wherein if the second scheduling information includes a second NDI, the second scheduling information is used for a retransmission downlink data packet with the second resource assignment, the second NDI indicating a second value.
