Abstract
The present specification provides a method performed by a node for transmitting beam informing information in a wireless communication system, and an apparatus therefor, the method comprising: performing an initial access with a parent node; determining the beam informing information; and transmitting, to the parent node, the beam informing information, wherein the beam informing information includes at least one of transmission (TX) beam information and reception (RX) beam information which is recommended for mobile terminal (MT) operation of the node.
Claims7
A method, comprising:
- transmitting, to a parent node, medium access control (MAC) control element (CE) comprising beam information by an integrated access and backhaul (IAB) node comprising an IAB-mobile terminal (MT) and an IAB-distributed unit (DU);
- and
- receiving, from the parent node, restricted beam information by the IAB node,
- wherein the beam information is related to at least one of an IAB-MT's recommended downlink beam and an IAB-MT's recommended uplink beam,
- wherein the restricted beam information comprises information for an IAB-DU's restricted beam, and
- wherein the restricted beam information further comprises information for IAB-MT's downlink or uplink beams which are related with the IAB-DU's restricted beam.
An integrated access and backhaul (IAB) node including an IAB-mobile terminal (MT) and an IAB-distributed unit (DU), the IAB node comprising:
- at least one transceiver;
- at least one memory;
- and
- at least one processor operatively coupled with the at least one memory and the at least one transceiver,
- wherein the at least one memory stores instructions that, based on being executed by the at least one processor, cause the at least one processor to perform operations comprising:
- transmitting, to a parent node, medium access control (MAC) control element (CE) comprising beam information;
- and
- receiving, from the parent node, restricted beam information,
- wherein the beam information is related to at least one of an IAB-MT's recommended downlink beam and an IAB-MT's recommended uplink beam,
- wherein the restricted beam information comprises information for an IAB-DU's restricted beam, and
- wherein the restricted beam information further comprises information for IAB-MT's downlink or uplink beams which are related with the IAB-DU's restricted beam.
A method, comprising:
- receiving, by a parent node, medium access control (MAC) control element (CE) comprising beam information from an integrated access and backhaul (IAB) node including an IAB-mobile terminal (MT) and an IAB-distributed unit (DU);
- and
- transmitting, by the parent node, restricted beam information to the IAB node,
- wherein the beam information is related to at least one of an IAB-MT's recommended downlink beam and an IAB-MT's recommended uplink beam,
- wherein the restricted beam information comprises information for an IAB-DU's restricted beam, and
- wherein the restricted beam information further comprises information for IAB-MT's downlink or uplink beams which are related with the IAB-DU's restricted beam.
