Abstract: Certain aspects of the present disclosure provide techniques that may allow a base station and user equipment (UE) to be in agreement on spatial quasi co-location (QCL) assumptions for transmission in certain scenarios. The techniques may be used, for example, to determine QCL assumptions for downlink transmissions sent in an initial control resource set (CORESET) on an initial downlink bandwidth part (BWP) where dedicated signaling of such assumptions may be lacking. In some cases, the techniques may involve a UE determining a beam to use for monitoring for a physical downlink control channel (PDCCH) transmission on the initial CORESET in the initial downlink BWP that lacks dedicated signaling of QCL information and monitoring for the PDCCH on the initial CORESET in the initial BWP using the determined beam. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) identifying a priority scheme for a set of signals including a first set of synchronization signal block (SSB) signals associated with a first frequency range, a second set of SSB signals associated with a second frequency range, and a paging signal associated with the first frequency range. The UE may then monitor, via a narrowband processor of the UE and based on the priority scheme, a set of time resources for one or more of the first set of SSB signals, the second set of SSB signals, or the paging signal. The narrowband processor may be configured to process signals received via the first frequency range and the second frequency range.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that uplink communications are to be performed between the UE and a first cell group associated with a first radio access technology (RAT) and between the UE and a second cell group associated with a second RAT. The UE may determine that the UE is configured for power sharing for the uplink communications with the first cell group associated with the first RAT and the second cell group associated with the second RAT. The UE may calculate, based on the power sharing and the uplink communications, a power reduction factor for the uplink communications between the UE and the second cell group. The UE may perform the uplink communications with the first cell group and selectively perform the uplink communications with the second cell group.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first slot format configuration for a first cell associated with a first radio access technology (RAT) and a first radio frequency spectrum band that conflicts with a second slot format configuration for a second cell associated with a second RAT and a second radio frequency spectrum band during at least a portion of a transmission time interval (TTI). The UE may determine that the first cell has a priority over the second cell, based on the configured slot formats or based on the radio frequency bands, and may drop a communication on the second cell based on the identified priority. The UE may then communicate during at least a portion of the TTI on the first cell while the UE drops a communication on the second cell.

Abstract: Different sets of downlink control information (DCI) fields may be configured for DCI that includes an indication to trigger bandwidth part switching at a user equipment (UE). For example, a UE may receive DCI that triggers the UE to switch operation from a first bandwidth part to a second bandwidth part. The UE may also identify a set of transformable DCI fields and a set of non-transformable DCI fields within the DCI. The UE may then determine updated content of the DCI for application to the second bandwidth part based on whether DCI fields are included in the set of transformable or the set of non-transformable fields. In some cases, the UE may identify a null assignment in the received DCI and may switch its operation from the first bandwidth part to the second bandwidth part based on the null assignment.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may operate in a radio resource control (RRC) inactive state of a discontinuous reception (DRX) mode. The UE may receive one or more synchronization signal blocks (SSBs) over a serving single frequency network (SFN) for a first notification zone, wherein the first notification zone comprises a plurality of cells. The UE may perform a channel measurement procedure using the received one or more SSBs. The UE may determine, based at least in part on a result of the channel measurement procedure, that a channel performance metric for the serving SFN of the first notification zone fails to satisfy a threshold. The UE may perform a cell reselection procedure to identify a cell of a neighboring SFN for a second notification zone that has a channel performance metric satisfying the threshold.

Abstract: In an embodiment, a UE determines QCL information that indicates an association between a spatial parameter and a current transmission configuration, and conveys the determined QCL information to a BS. In another embodiment, a BS transmits a DCI that triggers transmission of a reference signal that includes QCL information that indicates an association between a spatial parameter and a current transmission configuration, whereby any DCI triggering any reference signal that includes any QCL information is configured to trigger a UE to send an express acknowledgment or an implied acknowledgment to that DCI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink message that includes a control channel monitoring periodicity and control channel offset for a radio frame. A UE may identify a set of slots within a radio frame to monitor for downlink control information (DCI) based on the received downlink message. The UE may identify a control channel candidate within a search space of each slot of the set of slots, and may identify the control channel candidate of a first slot based on calculations that include a current slot and a previous slot. There may be one or more slots that occur between the previous slot and the current slot. The UE may receive DCI that is user-specific based on the identified control channel candidate.
