Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. The UE may identify that the UE is operating in a high mobility environment, that a first reference signal received power associated with a first cell is decreasing, and that a second reference signal received power associated with a second cell is increasing. The UE may transmit a request for a handover from the first cell to the second cell based on the identifying, the transmitting performed at a time that may be based on one or more network-configured handover timing parameters having one or more values adjusted by the UE. The UE may receive a handover command in response to transmitting the request for handover. The UE may perform a handover from the first cell to the second cell in response to the handover command.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify, based at least in part a determination to transmit one or more packets, a scheduling request (SR) occasion in which to transmit an SR for uplink resources to transmit the one or more packets, the SR occasion occurring prior to a start of a connected discontinuous reception (CDRX) on duration of the UE. The UE may determine whether the SR occasion occurs within a threshold amount of time prior to the start of the CDRX on duration of the UE. The UE may transmit the SR in the SR occasion based at least in part on the determination of whether the SR occasion occurs within the threshold amount of time prior to the start of the CDRX on duration of the UE. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for improving inter-Radio Access Technology (RAT) measurements. A user equipment (UE) determines, while in a connected state Discontinuous Reception (CDRX) mode in a first cell of a first Radio Access Technology Network (RAT), that a second cell of a second RAT is to be measured. The UE schedules at least two operational periods related to transitioning between ON and OFF states of the CDRX mode to overlap, to increase a period available for measuring signals in the second cell.
