Method for slot format for backhaul and access link in wireless communication system and terminal using same method
摘要
說明書
The present disclosure proposes a method of scheduling/coordinating a transmission/reception direction and a transmission/reception timing between links in an IAB environment. Here, coordination may be replaced with the term “synchronization”.
The present disclosure will be described on the assumption of an in-band environment, but the present disclosure can be applied to an out-band environment.
In addition, although the present disclosure will be described in consideration of an environment in which a donor gNB (DgNB), a relay node (RN) and a UE perform half-duplex operation, the present disclosure can also be applied to an environment in which the DgNB, the RN and/or the UE perform full-duplex operation.
In the present disclosure, for convenience of description, when two nodes DgNB and RN are present, the two nodes are node A and node B, and node A schedules node B (i.e., node B is associated with node A), a backhaul link that connects the two nodes is referred to as a node A-node B backhaul link. Likewise, when node A schedules UE 1 (i.e., node B is associated with node A), an access link that connects node A and UE 1 is referred to as a node A-UE 1 access link.
In addition, in the present disclosure, for convenience of description, a backhaul link with a node scheduled by a specific node is referred to as a backhaul link of the corresponding node and an access link with a UE scheduled by the specific node is referred to as an access link of the corresponding node. That is, an RN1-RN2 backhaul link and an RN1-RN3 backhaul link are backhaul links of RN1 and an RN1-UE2 access link and an RN1-UE4 access link are access links of RN1, for example.
