Abstract: Aspects relate to wireless communication using multiple active bandwidth parts (BWPs). For example, a base station may configure a user equipment (UE) with two or more active BWPs. The UE may then use one or more of the active BWPS at a time. For example, the UE may use multiple active BWPs for full duplex communication. Alternatively, or in addition, the UE may switch between active BWPs under various configurations, based on UE capabilities.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device (such as a user equipment (UE)) may receive from a transmitting device (such as a base station), a configuration of full duplex communication resources for a set of slots. The receiving device may receive a pre-emption indication identifying that at least a portion of the full duplex communication resources in one or more slots of the set of slots is unavailable for communication, and may determine a remaining portion of the full duplex communication resources in the one or more slots based on the received pre-emption indication. The receiving device may then communicate with the transmitting device using the remaining portion of the full duplex communication resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, downlink control information (DCI) that includes a semi-persistent scheduling (SPS) activation indication. The UE may receive, from the network node, an SPS physical downlink shared channel (PDSCH) based at least in part on the SPS activation indication, wherein the SPS PDSCH is associated with one or more transmission parameters that are based at least in part on an antenna adaptation configuration applicable to the SPS PDSCH. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for fast adaptation of transmission properties of sounding reference signal (SRS) resource sets. A method that may be performed by a user equipment (UE) includes receiving sounding reference signal (SRS) configuration information, configuring the UE with one or more SRS resource sets, wherein each of the one or more SRS resource sets comprises one or more SRS resources; receiving signaling comprising a field indicating which of the one or more SRS resources in the one or more SRS resource sets are active and which of the one or more SRS resources in the one or more SRS resources sets are inactive; and transmitting one or more SRSs using only the one or more SRS resources that are active.

Abstract: A base station may configure a user equipment for reporting channel state information for non-contiguous downlink channels such as sub-band full duplexed downlink channels. The user equipment may report the channel state information for the non-contiguous downlink channels utilizing a single channel state information report.

Abstract: Certain aspects of the present disclosure provide techniques for handling collisions between PUCCH/PUSCH carrying certain reporting and sounding reference signals (SRS). The techniques provide rules that a user equipment (UE) may apply to decide if and when to drop SRS or PUCCH/PUSCH transmissions scheduled on overlapping time resources in different component carriers.

Abstract: Methods, systems, and devices for wireless communications are described. The techniques described herein may enable frequency domain interleaving for a transmission direction depending on a codeblock mapping configuration, a transport block size, or both. For example, a device (e.g., a user equipment (UE) or a base station) may use an existence of self-interference (e.g., existence of communications in a different transmission direction), a frequency domain allocation, a codeblock size, a number of codeblocks mapped per symbol, or a combination thereof for determining the interleaving. Additionally, the device may determine the frequency domain interleaving based on a transport block size configured for a transmission direction in a full-duplex slot. For example, a table with different ranges of transport block size along with interleaver depth or different interleaver patterns may be configured, and the device can determine the interleaver design based on the table.

Abstract: A user equipment (UE) may spatial time-division multiplex a plurality of sounding reference signal (SRS) ports, each of the plurality of SRS ports being associated with at least one of a set of orthogonal weights, the set of orthogonal weights corresponding to phase shifting, and transmit a plurality of SRSs via the plurality of spatially time-division multiplexed SRS ports simultaneously, each of the plurality of SRSs including at least two SRS repetition. The plurality of SRSs may be configured to form or present a quasi-co-location (QCL) receive (Rx) beam subspace. The UE may configure the plurality of SRSs to form the subspace as the QCL Rx beam subspace, and a base station may signal the UE to a specific Rx beam subspace such that it is aligned to the base station's beamforming direction, and achieve spatial multiplexing gain in the QCL Rx beam subspace.
