A second SR for a buffer status reporting procedure is transmitted. A downlink control information comprising an uplink grant is received via a downlink control channel while the first SR and the second SR are pending. Based on the reception of the downlink control information: the second SR for the buffer status reporting procedure is cancelled, and the first SR for the beam failure recovery procedure is kept pending. ## Claims ### Claim 1 A method, comprising: transmitting, by a wireless device, a first scheduling request (SR), in response to initiating a beam failure recovery procedure; transmitting a second SR for a buffer status reporting procedure; receiving, via a downlink control channel and while the first SR and the second SR are pending, a downlink control information comprising an uplink grant; and based on the receiving the downlink control information: cancelling the second SR for the buffer status reporting procedure; and keeping pending the first SR for the beam failure recovery procedure. ### Claim 2 (depends on 1) The method of claim 1, further comprising receiving one or more messages indicating first configuration parameters of the first SR and second configuration parameters of the second SR. ### Claim 3 (depends on 1) The method of claim 1, wherein the transmitting the first SR comprises transmitting the first SR via first uplink control channel resources configured for the first SR. ### Claim 4 (depends on 1) The method of claim 1, wherein the transmitting the second SR comprises transmitting the second SR via second uplink control channel resources configured for the second SR. ### Claim 5 (depends on 1) The method of claim 1, further comprising transmitting a buffer status report via uplink resources associated with the uplink grant. ### Claim 6 (depends on 1) The method of claim 1, further comprising completing the beam failure recovery procedure and canceling the first SR. ### Claim 7 (depends on 1) The method of claim 1, further comprising completing the beam failure recovery procedure in response to cancelling the second SR. ### Claim 8 (depends on 1) The method of claim 1, wherein the wireless device initiates the beam failure recovery procedure in response to detecting one or more reference signals being lower than one or more first thresholds. ### Claim 9 (depends on 8) The method of claim 8, further comprising selecting, based on one or more second thresholds in response to initiating the beam failure recovery procedure, a reference signal from a plurality of reference signals. ### Claim 10 (depends on 9) The method of claim 9, wherein the second SR indicates at least one of: a number of detected beam failure instances; and the reference signal. ### Claim 11 A wireless device, comprising: one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the wireless device to: transmit a first scheduling request (SR), in response to initiating a beam failure recovery procedure; transmit a second SR for a buffer status reporting procedure; receive, via a downlink control channel and while the first SR and the second SR are pending, a downlink control information comprising an uplink grant; and based on the reception of the downlink control information: cancel the second SR for the buffer status reporting procedure; and keep pending the first SR for the beam failure recovery procedure. ### Claim 12 (depends on 11) The wireless device of claim 11, wherein the instructions, when executed by the one or more processors, further cause the wireless device to receive one or more messages indicating first configuration parameters of the first SR and second configuration parameters of the second SR. ### Claim 13 (depends on 11) The wireless device of claim 11, wherein the transmission of the first SR comprises transmitting the first SR via first uplink control channel resources configured for the first SR. ### Claim 14 (depends on 11) The wireless device of claim 11, wherein the transmission of the second SR comprises transmitting the second SR via second uplink control channel resources configured for the second SR. ### Claim 15 (depends on 11) The wireless device of claim 11, wherein the instructions, when executed by the one or more processors, further cause the wireless device to transmit a buffer status report via uplink resources associated with the uplink grant. ### Claim 16 (depends on 11) The wireless device of claim 11, wherein the instructions, when executed by the one or more processors, further cause the wireless device to complete the beam failure recovery procedure and cancel the first SR. ### Claim 17 (depends on 11) The wireless device of claim 11, wherein the wireless device initiates the beam failure recovery procedure in response to detecting one or more reference signals being lower than one or more first thresholds. ### Claim 18 (depends on 17) The wireless device of claim 17, wherein the instructions, when executed by the one or more processors, further cause the wireless device to select, based on one or more second thresholds in response to initiating the beam failure recovery procedure, a reference signal from a plurality of reference signals. ### Claim 19 (depends on 18) The wireless device of claim 18, wherein the second SR indicates at least one of: a number of detected beam failure instances; and the reference signal. ### Claim 20 A system comprising: a wireless device, comprising: one or more first processors; and first memory storing first instructions that, when executed by the one or more first processors, cause the wireless device to: transmit a first scheduling request (SR), in response to initiating a beam failure recovery procedure; transmit a second SR for a buffer status reporting procedure; receive, via a downlink control channel and while the first SR and the second SR are pending, a downlink control information comprising an uplink grant; and based on the reception of the downlink control information: cancel the second SR for the buffer status reporting procedure; and keep pending the first SR for the beam failure recovery procedure; and a base station, comprising: one or more second processors; and second memory storing second instructions that, when executed by the one or more second processors, cause the base station to: receive the first SR; receive the second SR; and transmit, via the downlink control channel and while the first SR and the second SR are pending, the downlink control information.
