A base station can configure a user equipment (UE) to monitor a channel/signal on multiple beams. The base station can transmit the multiple beams to the UE, which are at different time periods in a monitoring window. The UE can then monitor the multiple beams within the monitoring window and determine a monitoring report. The UE can then transmit the monitoring report to the base station, wherein the monitoring report indicates a subset of multiple beams as being more or less suitable for communication. The base station can also indicate that it will stop transmitting one or more beams and then stop transmitting the beams. If the UE does not send the report, the base station can continue to transmit the multiple beams. ## Claims ### Claim 1 A method of wireless communication at a user equipment (UE) for monitoring beams, comprising: receiving a configuration for monitoring a channel or signal on two or more beams from a base station; monitoring the two or more beams from the base station in a monitoring window, wherein the channel or signal is received on the two or more beams at different time or frequency periods in the monitoring window; determining a monitoring report based on the two or more beams; and refraining from monitoring at least one of the two or more beams at an end of the monitoring window based on the monitoring report. ### Claim 2 (depends on 1) The method of claim 1, further comprising: transmitting the monitoring report to the base station within the monitoring window. ### Claim 3 (depends on 2) The method of claim 2, wherein refraining from monitoring at least one of the two or more beams at the end of the monitoring window based on the monitoring report comprises: refraining from monitoring at least one of the two or more beams when the monitoring report is transmitted to the base station or at an end of a time window after transmitting the monitoring report to the base station. ### Claim 4 (depends on 1) The method of claim 1, wherein the channel or signal is a control channel. ### Claim 5 (depends on 1) The method of claim 1, wherein the channel or signal is a data channel. ### Claim 6 (depends on 1) The method of claim 1, wherein the channel or signal is a demodulation reference signal (DMRS) associated with a control channel or a data channel. ### Claim 7 (depends on 1) The method of claim 1, wherein the channel or signal comprises a Control Resource Set (CORESET). ### Claim 8 (depends on 7) The method of claim 7, wherein the UE monitors each of the two or more beams for one or more channels or signals based on a CORESET configuration. ### Claim 9 (depends on 7) The method of claim 7, wherein a different CORESET is configured for each of the two or more beams. ### Claim 10 (depends on 9) The method of claim 9, wherein the configuration for the two or more beams comprises a search space configuration providing time-domain monitoring for the CORESET. ### Claim 11 (depends on 1) The method of claim 1, wherein the monitoring report indicates a subset of the two or more beams as either being less suitable or as being more suitable for communication from the base station to the UE. ### Claim 12 (depends on 11) The method of claim 11, further comprising: receiving an indication from the base station that the base station will stop transmitting on at least one of the two or more beams in response to the monitoring report. ### Claim 13 (depends on 11) The method of claim 11, wherein the monitoring report is based on a reception quality of the two or more beams. ### Claim 14 (depends on 12) The method of claim 12, wherein the indication is received via direct signaling from the base station comprising at least one of downlink control information, radio resource control signaling, or a control element. ### Claim 15 A method of wireless communication at a base station for transmitting beams, comprising: configuring a user equipment (UE) to monitor a channel or signal on two or more beams; transmitting the channel or signal on the two or more beams to the UE, wherein the channel or signal is transmitted on the two or more beams at different time or frequency periods in a monitoring window; receiving a monitoring report from the UE based on the two or more beams; and refraining from transmitting the channel or signal to the UE on at least one of the two or more beams based on the monitoring report received from the UE. ### Claim 16 (depends on 15) The method of claim 15, wherein the monitoring report indicates a subset of the two or more beams as being either less suitable or as being more suitable for communication from the base station to the UE. ### Claim 17 (depends on 16) The method of claim 16, further comprising: transmitting an indication to the UE that the base station will stop transmitting to the UE on at least one of the two or more beams. ### Claim 18 (depends on 16) The method of claim 16, wherein the monitoring report is based on a reception quality of the two or more beams. ### Claim 19 (depends on 17) The method of claim 17, wherein the indication is transmitted to the UE via direct signaling comprising at least one of downlink control information, radio resource control signaling, or a control element. ### Claim 20 (depends on 15) The method of claim 15, wherein the channel or signal comprises a Control Resource Set (CORESET). ### Claim 21 (depends on 20) The method of claim 20, wherein a different CORESET is configured for each of the two or more beams. ### Claim 22 (depends on 21) The method of claim 21, wherein configuring the CORESET comprises a search space configuration providing time-domain monitoring for one or more CORESETs. ### Claim 23 (depends on 15) The method of claim 15, wherein the channel or signal is a control channel. ### Claim 24 (depends on 15) The method of claim 15, wherein the channel or signal is a data channel. ### Claim 25 (depends on 15) The method of claim 15, wherein the channel or signal is a demodulation reference signal (DMRS) associated with a control channel or a data channel. ### Claim 26 An apparatus for wireless communication at a User Equipment (UE), comprising: a memory;
