Configuration for Beam Failure Recovery
| Content Provider | The Lens |
|---|---|
| Abstract | Systems, apparatuses, and methods are described for wireless communications. A base station may send configuration information for a beam failure recovery (BFR) procedure. A wireless device may determine, based on the configuration information, one or more transmission beam parameters for the BFR procedure. The wireless device may indicate, via an uplink control channel, one or more candidate beams of the base station. |

| Claim | A method comprising: receiving, by a wireless device, one or more configuration parameters associated with a beam failure recovery (BFR) procedure, wherein the one or more configuration parameters comprise: a plurality of reference signal (RS) resources; and an RS resource index associated with an uplink control channel; determining, from the plurality of RS resources, a first RS resource for the BFR procedure; determining, based on the RS resource index, one or more transmission beam parameters for the uplink control channel; and indicating the first RS resource by transmitting, based on the one or more transmission beam parameters and via the uplink control channel, uplink control information for the BFR procedure. The method of claim 1, further comprising: initiating, based on one or more beam failures, the BFR procedure, wherein the first RS resource is associated with a candidate beam of a base station, wherein the determining the one or more transmission beam parameters for the uplink control channel comprises determining, based on the RS resource index, a beam of the wireless device, and wherein the transmitting the uplink control information for the BFR procedure is based on the beam of the wireless device. The method of any of the preceding claims, wherein the one or more configuration parameters comprise configuration parameters of a physical uplink control channel (PUCCH) for the BFR procedure, and wherein the uplink control information comprises at least one of: information indicating the first RS resource; or a reference signal received power value of the first RS resource. The method of any of claims 1 or 2, wherein the one or more configuration parameters indicate a plurality of uplink control channel resources each associated with a different RS resource of the plurality of RS resources; and wherein the method further comprises: selecting, from the plurality of uplink control channel resources and based on the first RS resource, a first uplink control channel resource; and determining, based on the first uplink control channel resource, the uplink control channe The method of any of the preceding claims, wherein the first RS resource comprises at least one of: one or more channel state information RS resources; or one or more synchronization signal blocks. The method of any of the preceding claims, wherein the RS resource index indicates at least one of: one or more channel state information RS resources; one or more synchronization signal blocks; or one or more sounding reference signal resources. The method of any of the preceding claims, wherein the RS resource index associated with the uplink control channel indicates a candidate transmission beam of the wireless device. The method of any of claims 1, 2, or 4 - 7, wherein the uplink control channel is associated with the first RS resource. The method of any of the preceding claims, further comprising transmitting, from the wireless device, a capability indication message indicating that a beam correspondence is not supported. The method of claim 1, wherein the first RS resource is associated with a candidate beam of a base station, and wherein the uplink control information or the uplink control channel indicates a selection of the candidate beam of the base station. The method of any of the preceding claims, further comprising: measuring channel qualities of the plurality of RS resources; and determining that the channel quality of the first RS resource satisfies one or more thresholds. The method of any of the preceding claims, further comprising: determining, based on a channel quality of a second RS resource, a beam failure instance, wherein the second RS resource is associated with a serving beam of a base station. A computing device comprising: one or more processors; and memory storing instructions that, when executed, cause the computing device to perform the method of any of claims 1 - 12. A system comprising: a first computing device configured to perform the method of any of claims 1 - 12; and a second computing device configured to send the one or more configuration parameters. A computer-readable medium storing instructions that, when executed, cause the performance of the method of any of claims 1 - 12. |
