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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a UE capability message associated with a number of downlink multiple-input and multiple-output (MIMO) layers supported at the UE. The UE may receive a configuration for a set of downlink MIMO layers including a first subset of downlink MIMO layers configured for a first cell and a second subset of downlink MIMO layers configured for a second cell. The UE may allocate a first set of resources to the first cell or the second cell, or both, based on the first and the second subset of downlink MIMO layers. The UE may determine a second set of resources are unallocated to the set of downlink MIMO layers and allocate the second set of resources to the first cell or the second cell, or both.

Abstract: Apparatus, methods, and computer-readable media for enhanced inter-frequency detection between misaligned base stations are disclosed herein. A user equipment (UE) may determine that a neighbor cell associated with a first frequency is misaligned with a serving cell associated with a second frequency different than the first frequency based on first measurements of the neighbor cell within a first measurement gap window having a first length. The UE may detect a location of a synchronization signal block (SSB) associated with the neighbor cell within a second measurement gap window having a second length greater than the first length. The UE may determine an alignment offset between the location of the SSB and the first measurement gap window. The UE may obtain second measurements of the neighbor cell within a third measurement gap window that includes the location of the SSB based on the alignment offset and parameters of the SSB.
