Method for slot format for backhaul and access link in wireless communication system and terminal using same method
摘要
說明書
In other aspect, a processor of a wireless communication device in a wireless communication system, wherein the processor is configured to cause the wireless communication device to: perform a first data transmission or reception to or from a UE on an access link on the basis of a first timing case in an access time duration and perform a second data transmission or reception to or from a second node or a donor base station on a backhaul link on the basis of a second timing case in a backhaul time duration, wherein downlink transmission timings over the donor base station, the first node, the second node and the UE are aligned in the first timing case, and downlink and uplink transmission timings or downlink and uplink reception timings are aligned in the first node in the second timing case.
According to the present disclosure, it is possible to support legacy UEs. UEs can reuse the existing specifications and thus impact on change of communication specifications can be mitigated. In addition, since downlink timings of UEs can be aligned in an access timing duration, interference caused by downlink communication performed by a certain UE and uplink communication performed by another UE in the access timing duration can be alleviated. Furthermore, an access timing duration and a backhaul timing duration are time-division-multiplexed and timing case 1 is applied in the access timing duration, and thus an access link may not be affected by change of a backhaul link route change unless a serving node is changed.
