US 12,010,659 B2 · Techniques for a radio access network entity to adjust timing in wireless networks

Abstract

Aspects provide for autonomous adjustment of the uplink and downlink transmission timing in wireless communication networks. A radio access network (RAN) entity (e.g., a scheduling entity, such as a base station or parent integrated access backhaul (IAB) node, or a centralized network node, such as an IAB donor node central unit) may provide support to a scheduled entity (e.g., a user equipment (UE) or child IAB node) to operate in an autonomous time adjustment (ATA) mode to autonomously adjust its uplink transmission timing to compensate for the change in downlink reception timing. The RAN entity may generate ATA mode information related to the ATA mode for the scheduled entity and transit the ATA mode information to the scheduled entity.

Dependent claims

A method of wireless communication at a radio access network (RAN) entity within a wireless communication network, comprising:

generating, by the RAN entity, autonomous time adjustment (ATA) mode information comprising one or more confidence parameters for determining whether a scheduled entity may enter an ATA mode within which the scheduled entity can autonomously adjust an uplink transmission timing of the scheduled entity based on a change in downlink reception timing of downlink signals received by the scheduled entity from a scheduling entity, the scheduled entity configured in a first IAB node and the scheduling entity configured in a second IAB node;
and
transmitting the ATA mode information to the scheduled entity.

A radio access network (RAN) entity within a wireless communication network, comprising:

a transceiver configured to communicate with a scheduled entity in the wireless communication network;
a memory;
and
a processor coupled to the transceiver and the memory, wherein the processor and the memory are configured to:
generate, by the RAN entity, autonomous time adjustment (ATA) mode information indicating comprising one or more confidence parameters for determining whether a scheduled entity may enter an ATA mode within which the scheduled entity can autonomously adjust an uplink transmission timing of the scheduled entity based on a change in downlink reception timing of downlink signals received by the scheduled entity from a scheduling entity, the scheduled entity configured in a first IAB node and the scheduling entity configured in a second IAB node;
and
transmit the ATA mode information to the scheduled entity via the transceiver.
