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 communication are described. A first user equipment (UE) may receive a control message that includes an indication to mute communications between the first UE and a second UE. The indication may be applicable to at least one communication link between the first UE and the second UE. The indication may include an identifier of the first UE, an identifier of the second UE, or an identifier of the at least one communication link. The first UE may receive the indication based on a power status of the first UE, a power status of the second UE, a reliability metric associated with the at least one communication link, or an interference metric associated with a network entity. Accordingly, the first UE may determine that the at least one communication link is muted for a time duration based on the indication.

Abstract: Methods, systems, and devices for wireless communications are described for beam selection based on user pose information provided by an extended reality (XR) application. The pose information may be used to determine a position of the UE, and one or more beam parameters may be requested based on the position of the UE. The position information of the UE may include position information for a current time period, predictive position information for one or more future time periods, or any combinations thereof. The UE may transmit a beam request to a base station for one or more beams for the current time period, for one or more future time periods, or any combinations thereof. The UE may request a switch between beams of differing beamwidths or having the same beamwidth, or request a change of a beamwidth of an existing beam.

Abstract: Methods, systems, and devices are described that support techniques for wireless communications using multiple radio access technologies (RATs). Described techniques provide for dual-connectivity (DC), carrier aggregation, or both, in which different carriers are provided via different RATs. A multi-RAT DC configuration may include separate network entities that provide communications for different cell groups for different RATs, where dynamic power control may be implemented across RATs. Additionally, or alternatively, a multi-RAT carrier aggregation techniques may provide separate component carriers configured for carrier aggregation, where different component carriers that use different RATs. Combinations of DC and carrier aggregation may be provided, in which a cell group of a DC configuration may include multiple component carriers in a carrier aggregation scheme.

Abstract: Techniques for signaling varied modulation and coding schemes for wireless communication are discussed. A method of wireless communication may comprise receiving, by a user equipment (UE), an indication to apply a modulation order cap to determine a first modulation and coding scheme for transmission of uplink control information different from a second modulation and coding scheme for transmission of data. The method may further comprise transmitting the uplink control information using the first modulation and coding scheme, wherein the first modulation and coding scheme is determined based, at least in part, on the received indication to apply the modulation order cap.

Abstract: Methods, systems, and devices for wireless communications are described that provide for an indication of a channel state by a user equipment (UE) that can be used to select transmission parameters for a downlink broadcast transmission. A network entity may transmit a first downlink transmission that may be received at a UE and used to measure a channel quality at the UE. The UE may transmit an uplink communication that provides an indication of the channel quality. The network device may receive the uplink communication, determine one or more transmission parameters for a broadcast downlink transmission based on the indication of the channel quality, and transmit the broadcast downlink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A device (such as a first user equipment (UE)) may communicate control signaling indicating a resource allocation for a sidelink channel. The first UE may receive, from a second UE, a first resource map. The first resource map may indicate a first sidelink transmission scheduled within a first time and frequency resource of the resource allocation, a first priority level of the first resource map, and a parameter threshold used to generate the first resource map. In some cases, the first UE may communicate a second sidelink transmission within the resource allocation for the sidelink channel based on the first resource map.

Abstract: Methods, systems, and devices for wireless communication are described that support sounding reference signal (SRS) transmission in low latency wireless transmissions. A set of shortened transmission time intervals (sTTIs) for uplink transmissions of a first wireless service may be identified; the set of sTTIs located within subframe time boundaries of a subframe of a second wireless service with a longer TTI than the sTTIs. Two or more sTTIs within the set of sTTIs may be used for SRS transmissions within the subframe time boundaries.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a resource configuration for communications with a base station on a multiple sets of resources across multiple component carriers, the resource configuration including at least a first set of resources on a first component carrier and a second set of resources on a second component carrier. The UE may receive, from the base station, a downlink control information (DCI) message on the first component carrier, the DCI message including a DCI format that controls the multiple of sets of resources across the plurality of component carriers. The UE may determine that the first set of resources and the second set of resources are one of activated or released based on a first indication in the DCI message.
