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.

說明書

FIG. 43 is a block diagram of a device of performing data transmission and/or reception on an access link and a backhaul link from the viewpoint of the first node according to an embodiment of the present disclosure.

Referring to FIG. 43, a processor 4300 may include a transmitter (and/or receiver) 4310. Here, the processor may correspond to processors of FIGS. 47 to 49 which will be described later.

The transmitter (and/or receiver) 4310 may be configured to perform data transmission/reception to/from a UE on an access link on the basis of the first timing case in an access time duration. In addition, the transmitter (and/or receiver) 4310 may be configured to perform data transmission/reception to/from the second IAB node or the donor base station on a backhaul link on the basis of the second timing case in a backhaul time duration. Here, DL transmission timings over the donor base station, the first node, the second node and the UE can be aligned in the first timing case, and DL and UL transmission timings or DL and UL reception timings can be aligned in the first node in the second timing case, as described above.

Since the method of performing data transmission and/or reception on an access link and a backhaul link from the viewpoint of the first node has been described above in detail, redundant description is omitted for convenience.

The example of FIG. 39 will be described below from the viewpoint of a donor base station (e.g., donor gNB or donor eNB).
