摘要
The present disclosure provides a method for data transmission or reception performed by a first node in a wireless communication system, the method including: performing 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 performing 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.

The above-described example with respect to option A will be described below in more detail.
In a situation such as option A, slot boundaries with respect to links (an access link with a UE and a backhaul link with a child node) on which a node performs scheduling can be configured as follows. (Slot boundaries may mean boundaries of multiple slots in the present disclosure).
-
- Alt 1. A period from a period in which DL starts to a period in which another DL starts may be a slot boundary. In this case, G_UD and/or G_DU periods may be included in a slot.
- Alt 2. A period from a period in which DL starts to a period in which the next DL starts may be a slot boundary. In this case, G_UD and/or G_DU periods may be included in a slot.
- Alt 3. A period from a period in which DL starts to a period in which UL ends may be a slot boundary. Here, only one DL period and one UL period can be present in the slot boundary. In this case, a G_DU period may be included in a slot. Furthermore, in this case, a slot length can be set to be less than a conventional slot length by G_UD. In addition, a gap of G_UD may be present between slots.
- Alt 4. A period from a period in which DL starts to a period in which UL ends may be a slot boundary. Here, a plurality of DL periods and only one UL period can be present in the slot boundary. In this case, a G_DU period may be included in a slot. Furthermore, in this case, a slot length can be set to be less than a conventional slot length by G_UD. In addition, a gap of G_UD may be present between slots.
