US 11,910,262 B2 · Radio link management for ultra-reliable low-latency communication

Abstract

Aspects relate to radio link management for a first type of link that is a high reliability, low-latency communication link such as ultra-reliable, low-latency communication (URLLC). Radio link failure (RLF) of the link may be determined in a wireless device that then transmits a link recovery request (LRR) communicating the RLF and a request for link recovery to a network in a reserved resource in an uplink channel using a second type of link that does not have as high priority (e.g., not as high reliability or as low-latency) as the first type of link, such as enhanced mobile broadband (eMBB). The wireless device receives a grant of uplink resources from the network responsive to the LRR, where the uplink resources are used by the wireless device to transmit an RLF report to the network and are also of the second type of link.

Dependent claims

A method for wireless communication at a user equipment (UE) in a wireless communication network, the method comprising:

transmitting a link recovery request (LRR) in a reserved resource in a first uplink channel to a base station of a serving cell in response to sensing a radio link failure (RLF) of a first link of a first type of service having a higher priority than a second type of service that are both capable of being provided in the serving cell, wherein the first uplink channel utilizes the second type of service on the serving cell;
receiving a grant of uplink (UL) resources from the base station in response to the transmitted LRR;
and
transmitting an RLF report in a second uplink channel utilizing the second type of service on the serving cell based on the receiving the grant of UL resources from the base station.

1 more element

A user equipment (UE) in a wireless communication network, comprising:

a wireless transceiver;
a memory;
and
a processor communicatively coupled to the wireless transceiver and the memory, wherein the processor and the memory are configured to:
transmit a link recovery request (LRR) in a reserved resource in a first uplink channel to a base station of a serving cell in response to sensing a radio link failure (RLF) of a first link of a first type of service having a higher priority than a second type of service that are both capable of being provided in the serving cell, wherein the first uplink channel utilizes the second type of service on the serving cell;
receive a grant of uplink (UL) resources from the base station in response to the transmitted LRR;
and
transmit an RLF report in a second uplink channel utilizing the second type of service on the serving cell based on the receiving the grant of UL resources from the base station.
