Abstract: An apparatus for wireless communication, including a memory and at least one processor coupled to the memory. The at least one processor is configured to receive a pre-allocation resource for a target cell via a handover command and transmit a physical layer acknowledgment based on a target cell downlink packet. The at least one processor is also configured to receive an indication for a communication with the target cell in response to the physical layer acknowledgement and access the target cell using the pre-allocated resource based on the indication for the communication with the target cell.

Abstract: Aspects of the present disclosure generally relate to wireless communication. For example, aspects of the present disclosure provide techniques for determining one or more modulation orders to be used for the communication of control channels and/or data channels. An exemplary method, performed by a UE, may include receiving downlink control information (DCI) that allocates resources for a communication, the DCI may include a first field that indicates a transport block size (TBS) of the communication and a second field, different from the first field, that indicates a modulation order of the communication, wherein the communication includes a transmission or a reception, and processing the communication according to the indicated modulation order. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a value for a phase tracking reference signal (PTRS) power boost for a PTRS port, wherein the PTRS port is associated with a sounding reference signal (SRS) resource set, wherein the value for the PTRS power boost is relative to each layer of physical uplink shared channel (PUSCH) per resource element (RE). The UE may transmit a PTRS associated with the PTRS port, and wherein a transmission power of the PTRS is based at least in part on the value for the PTRS power boost. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit capability information that indicates a power-level capability of each antenna group, of multiple antenna groups, wherein each antenna group is associated with one or more transmission antennas of at least eight transmission antennas associated with the UE. The UE may receive a scheduling communication that schedules an uplink communication using a selected precoder based at least in part on the capability information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information that schedules a physical downlink control channel (PDCCH) communication associated with a common search space (CSS) in a sub-band full duplex (SBFD) set of symbols. The UE may receive an indication of whether the SBFD set of symbols is to be treated as a non-SBFD set of symbols. The UE may perform one of receiving the PDCCH communication or refraining from receiving the PDCCH communication based on whether the SBFD set of symbols is to be treated as the non-SBFD set of symbols. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. A non-sidelink synchronization signal (SLSS)-transmitting user equipment (UE) may initiate a channel occupancy time (COT) including multiple contiguous slots and a gap slot. The non-SLSS UE may detect an SLSS UE (capable of transmitting sidelink synchronization signal blocks (S-SSBs)) and assume that the gap slot will be filled with an S-SSB. The non-SLSS may transmit a sidelink message during the COT after the gap slot, based on the assumption. Alternatively, based on the SLSS UE indicating that it is capable of transmitting the S-SSB, the non-SLSS UE may schedule transmission of the S-SSB such that the gap slot is filled. If the SLSS UE is incapable of transmitting the S-SSB, the non-SLSS UE may determine a method for transmitting the sidelink message during the already-initiated COT or during another COT.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive signaling identifying a control resource set (CORESET) puncturing pattern, the CORESET puncturing pattern being based, at least in part, on a number of resource blocks available before and after a CORESET puncturing process and a number of symbols of the CORESET. The UE may decode downlink control information in accordance with the CORESET puncturing pattern. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects more specifically relate to sidelink communications and PSFCH padding. In some aspects, a channel occupancy time (COT) initiating UE may obtain physical sidelink feedback channel (PSFCH) information indicating that a PSFCH transmission is to occupy a common interlace and one or more physical resource blocks. The COT initiating UE may communicate a padding signal within a PSFCH gap of the common interlace in accordance with identifying that the COT initiating UE and the responding UE are not to transmit hybrid automatic repeat request (HARQ) feedback within the PSFCH gap of the common interlace. In some other aspects, the PSFCH information may indicate that the PSFCH transmission is to occupy a dedicated interlace, and the COT initiating UE may communicate a padding signal on a PSFCH resource within the dedicated interlace.

Abstract: Certain aspects of the present disclosure provide techniques for processing multi-layer transmissions simultaneously received from multiple network entities. An example method for wireless communications by a user equipment (UE) includes obtaining a first channel matrix for spatially processing multi-layer transmissions from a first network entity received via a first antenna panel at the UE; obtaining a second channel matrix for spatially processing multi-layer transmissions from a second network entity received via a second antenna panel at the UE; and spatially processing one or more multi-layer transmissions from the first and second network entities simultaneously received via the first and second antenna panels at the UE, based on a third channel matrix including entries of the first channel matrix and entries of the second channel matrix.

Abstract: Apparatus, methods, and computer program products for wireless communication are provided. An example method may include establishing, with a second UE, a sidelink connection. The example method may further include transmitting, to the second UE, sidelink control information (SCI) indicating a demodulation reference signal (DM-RS) pattern from a list of DM-RS patterns including a single symbol DM-RS pattern, the DM-RS pattern being associated with a physical sidelink shared channel (PSSCH) transmission. The example method may further include transmitting, to the second UE based on the PSSCH transmission being associated with a phase tracking signal (PTRS), the PSSCH transmission with a DM-RS based on the single symbol DM-RS pattern and the PTRS associated with the PSSCH transmission.
