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: Example implementations include a method, apparatus and computer-readable medium of wireless communication. A user equipment (UE) may receive a configuration indicating whether a beam switching gap is expected at a first symbol position within a subframe of a physical channel for the UE, the first symbol position having a first cyclic prefix length that is longer than a second cyclic prefix length of a second symbol position within the subframe of the physical channel for the UE. The UE may determine whether a transmission includes a missing symbol for the beam switching gap based on the configuration and the symbol position of a symbol where a beam switch is scheduled.

Abstract: Methods, systems, and devices for wireless communications are described. In some aspects, a user equipment (UE) and a network entity may support one or more signaling-based mechanisms according to which the network entity may inform the UE of which time and frequency resources may be used for full-duplex communication. The network entity transmit a first message to configure multiple resource block (RB) sets for the UE, where each RB set is associated with unique identifying information. To inform the UE of which time and frequency resources may be used for full-duplex communication, the network entity may transmit a second message that indicates one or more slot formats on a per RB set basis. As such, the network entity may schedule the UE for full-duplex communication in accordance with indicating that overlapping symbols of a first RB set and a second RB set are allocated for uplink and downlink, respectively.

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, computer programs products, and apparatuses for RS availability indication are provided. An example method at a UE may include receiving, from a base station, a PEI comprising a first availability indication for a first set of RS resources in one or more RS occasions. The example method may further include receiving, from the base station, a paging PDCCH comprising a second availability indication for a second set of RS resources in the one or more RS occasions. The example method may further include receiving, from the base station, at least one of the first set of RS resources or the second set of RS resources.

Abstract: Aspects of the present disclosure provide techniques for sub-band conversion or cancellation for dynamic scheduling of sub-band full duplex (SBFD) operations between the base station and UEs. The capability to communicate via simultaneous UL and DL transmissions through dynamic scheduling allows for increased uplink duty cycle leading to latency reduction (e.g., it is possible to receive DL signal in an UL only slots, which can enable latency savings) and improved uplink coverage. Additionally enabling flexible and dynamic UL and DL resource adaptation in accordance with techniques of the present disclosure also provide enhanced system capacity, resource utilization, and spectrum efficiency.

Abstract: Inter-cell mobility across serving and non-serving cells based on layer 3 measurements is accomplished at the cost of increased delay. Inter-cell mobility across serving and non-serving cells based on layer 1 measurements minimized delay. A user equipment (UE) apparatus that is served by a serving cell of a base station receives, from the serving cell, a configuration to perform layer 1 (L1) measurements based on one or more reference signals from a non-serving cell. The UE also receives the one or more reference signals from the non-serving cell. The UE performs the L1 measurements on the one or more reference signals received from the non-serving cell based on the configuration received from the base station. The UE may perform the L1 measurements on a synchronization signal block (SSB), a channel state information reference signal (CSI-RS), or a positioning reference signal (PRS) from the non-serving cell.
