Abstract
The present specification provides a method for receiving gap symbol information, the method being performed by a node in a wireless communication system. The method is characterized by including: receiving the gap symbol information, wherein the gap symbol information indicates the number of gap symbols pertaining to switching between a mobile terminal (MT) operation and a distributed unit (DU) operation; and performing an integrated access and backhaul (IAB) operation on the basis of the gap symbol information, wherein the node does not perform the IAB operation on the symbol indicated by the gap symbol information.
Claims9
A method for an integrated access and backhaul (IAB) node in a wireless communication system, the method performed by the IAB node and comprising:
- receiving a provided guard symbols medium access control (MAC) control element (CE) from a parent IAB node,
- wherein the provided guard symbols MAC CE includes guard symbol information,
- wherein the guard symbol information indicates a number of guard symbols for switching between a mobile terminal (MT) operation and a distributed unit (DU) operation, and
- wherein the guard symbols will not be used for the IAB node.
An integrated access and backhaul (IAB) node comprising:
- a transceiver;
- at least one memory;
- and
- at least one processor being operatively connected to the at least one memory and the transceiver,
- wherein the at least one processor is configured to:
- control the transceiver to receive a provided guard symbols medium access control (MAC) control element (CE) from a parent IAB node,
- wherein the provided guard symbols MAC CE includes guard symbol information,
- wherein the guard symbol information indicates a number of guard symbols for switching between a mobile terminal (MT) operation and a distributed unit (DU) operation, and
- wherein the guard symbols will not be used for the IAB node.
An apparatus in an integrated access and backhaul (IAB) node, the apparatus comprising:
- at least one memory;
- and
- at least one processor being operatively connected to the at least one memory,
- wherein the at least one processor is configured to:
- control a transceiver to receive a provided guard symbols medium access control (MAC) control element (CE) from a parent IAB node,
- wherein the provided guard symbols MAC CE includes guard symbol information,
- wherein the guard symbol information indicates a number of guard symbols for switching between a mobile terminal (MT) operation and a distributed unit (DU) operation, and
- wherein the guard symbols will not be used for the IAB node.
