METHOD, USER EQUIPMENT AND BASE STATION FOR TRANSMITTING OR RECEIVING UPLINK SPS SERVICE DATA

摘要

Disclosed is a method for transmitting uplink semi-persistent scheduling SPS service data in a frequency division duplexing FDD system. The method comprises: initially transmitting or retransmitting a data packet using transmission time interval TTI bundling of an uplink SPS service; and when a retransmission indication of the data packet is received, retransmitting the data packet, wherein under the condition of ensuring that the transmission data does not collide, the size of the TTI bundling of the initially transmitted data packet is different from that of the TTI bundling of the retransmitted data packet and/or the round-trip time delay RTT of the initial transmission or the first retransmission is different from the RTT of two adjacent retransmissions. Correspondingly, also disclosed are a method, user equipment and a base station for receiving SPS service data. The present invention increases the transmission time density when SPS service uplink data is transmitted.
