Abstract
Disclosed are techniques for wireless communication. In an aspect, an integrated access and backhaul (IAB) node sets a downlink transmission timing of the IAB node relative to a downlink reception timing of the IAB node based on a first set of values for a set of timing parameters, receives, from a parent IAB node of the IAB node, a second set of values for the set of timing parameters, and transmits, to a positioning entity, a report indicating a change from the first set of values to the second set of values, a new downlink transmission timing based on the second set of values, or a change in downlink transmission timing.
Claims18
An integrated access and backhaul (IAB) node, comprising:
- a memory;
- at least one transceiver;
- and
- at least one processor communicatively coupled to the memory and the at least one transceiver, the at least one processor configured to:
- set a downlink transmission timing of the IAB node relative to a downlink reception timing of the IAB node based on a first set of values for a set of timing parameters;
- receive, from a parent IAB node of the IAB node, a second set of values for the set of timing parameters;
- cause the at least one transceiver to transmit, to a positioning entity after the second set of values from the parent IAB node is received by the IAB node, a report indicating the second set of values, a change from the first set of values to the second set of values, a new downlink transmission timing based on the second set of values, or a change in downlink transmission timing;
- and
- cause the at least one transceiver to transmit, to a central unit (CU) for the IAB node, an indication of the change from the first set of values to the second set of values for the set of timing parameters to enable the CU to identify duplicate changes to the set of timing parameters for IAB nodes served by the CU.
A method of wireless communication performed by an integrated access and backhaul (TAB) node, comprising:
- setting a downlink transmission timing of the TAB node relative to a downlink reception timing of the TAB node based on a first set of values for a set of timing parameters;
- receiving, from a parent TAB node of the TAB node, a second set of values for the set of timing parameters;
- transmitting, to a positioning entity after the second set of values from the parent TAB node is received by the TAB node, a report indicating the second set of values or a change from the first set of values to the second set of values, a new downlink transmission timing based on the second set of values, or a change in downlink transmission timing;
- and
- transmitting, to a central unit (CU) for the TAB node, an indication of the change from the first set of values to the second set of values for the set of timing parameters to enable the CU to identify duplicate changes to the set of timing parameters for TAB nodes served by the CU.
