US 2026/0100751 A1 · NETWORK-CONTROLLED REPEATER OPERATION DURING BEAM RECOVERY PROCEDURE OF THE BACKHAUL LINK

Abstract

Various aspects of the present disclosure relate to a device and method for a network-controlled repeater (NCR) device to detect, indicate, and recover from a backhaul failure. The method includes communicating, by the NCR device with: (i) base station(s) via a control link or a backhaul link and (ii) a user equipment (UE) via an access link. A beam association is determined of the control link and the backhaul link. The method includes determining that the control link is communicated on a first beam and the backhaul link is communicated on a second beam of the base station(s). In response, the method includes monitoring a reference signal received on the backhaul link for an indication of failure of the backhaul link. The method includes transmitting a request for backhaul beam recovery on the control link in response to detecting the indication of failure of the backhaul link.

Dependent claims

A repeater device for wireless communication, the repeater device comprising:

at least one memory;
and
at least one processor communicatively coupled to the at least one memory and which is configured to cause the repeater device to:
determine a beam association of a first link and a second link established with at least one base station;
monitor a reference signal received on the second link for an indication of backhaul failure of the second link;
and
in response to detecting the indication of backhaul failure of the second link, transmit a request for backhaul beam recovery on the first link.

4 more elements

A controller for wireless communication in a repeater device, the controller comprising:

at least one memory;
and
at least one processor communicatively coupled to the at least one memory and which is configured to cause the controller to:
determine a beam association of the first link and the second link established via at least one transceiver communicatively coupled to the controller and that enables the repeater device to communicate:
(i) with at least one network device of a network via (a) a first link or (b) a second link;
and (ii) with a user device via a third link;
monitor a reference signal received on the second link for an indication of backhaul failure of the second link;
and
in response to detecting the indication of backhaul failure of the second link, transmit a request for backhaul beam recovery on the first link.

6 more elements

A method for wireless communication at a repeater device, the method comprising:

determining a beam association of a first link and a second link established with at least one base station;
monitoring a reference signal received on the second link for an indication of backhaul failure of the second link;
and
in response to detecting the indication of backhaul failure of the second link, transmitting a request for backhaul beam recovery on the first link;
wherein the first link is a control link and the second link is a backhaul link.
