RELAXATION OF TIME ALIGNMENT TIMER PARAMETERS

Abstract: methods, systems, and devices for wireless communications are described. a user equipment (ue) may receive an indication of time alignment timer (tat) relaxation criteria for one or more time alignment timers at the ue. the ue may transmit a request or a status report for tat relaxation based on satisfying the time alignment timer relaxation criteria. the ue may receive an indication of tat relaxation parameters in response to the request or status report. the ue may apply the tat relaxation parameters to perform fewer measurements and transmit fewer measurement reports for uplink transmission. in some cases, reduced physical downlink control channel (pdcch) monitoring occasions and extended discontinuous reception (drx) can be jointly configured with the relaxation of tats for the ue.
