Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on a first carrier having a first subcarrier spacing (SCS), a scheduling indication via a physical downlink control channel (PDCCH) scheduling a downlink transmission on a second carrier having a second SCS. The UE may process the downlink transmission on the second carrier based at least in part on a delay between the PDCCH and the scheduled downlink transmission and a timing threshold having a basic term and an adjustment term. For example, the basic term may be based at least in part on a minimum delay between the PDCCH and the scheduled downlink transmission, and the adjustment term may be based at least in part on a processing time due to a difference between the first SCS and the second SCS. Numerous other aspects are provided.

Abstract: A method for wireless communication at a wireless device is disclosed herein. The method includes selecting a wideband precoder for a first set of antennas and a second set of antennas based on at least one matrix, where a number of the first set of antennas and the second set of antennas is greater than a maximum number of supported layers. The method includes calculating, based on the selected wideband precoder, a first set of performance metrics for the first set of antennas and a second set of performance metrics for the second set of antennas. The method includes combining the first set of performance metrics for the first set of antennas and the second set of performance metrics for the second set of antennas based on the calculation.

Abstract: Dynamic receiver switching is implemented by a receiving device that selects a first receiver having operating characteristics associated with a first optimal operating region to decode one or more first transmissions. The receiving device then selects a second receiver to decode subsequent transmissions. The second receiver has operating characteristics and an optimal operating region that are different from those of the receiver.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication scheduling. An example method that may be performed by a user equipment (UE) includes receiving, from a base station, one or more configurations indicating wireless communication resources including at least one of a plurality of bandwidth parts (BWP) or a plurality of component carriers (CCs); receiving, from the base station, control signaling indicating a scheduling offset to communicate with the base station via at last one of the BWPs within at least one of the CCs; determining a value of the scheduling offset based at least in part on a minimum scheduling offset value; and taking at least one action in response to the determination.

Abstract: Aspects of the disclosure relate to a wireless user equipment (UE) establishing and utilizing a reference timing for a carrier or cell with multiple transmission and reception points (TRPs). A UE may receive a downlink signal on each of a plurality of component carriers (CCs), and determine respective timing events (e.g., slot boundaries, subframe boundaries, etc.) corresponding to each of the plurality of CCs. The UE may then determine a reference time for a first CC of the plurality of CCs. This reference time corresponds to a function of two or more timing events corresponding to different TRPs utilizing the first CC. The UE then determines a relative timing difference between the plurality of CCs based on this determined reference time. Other aspects, embodiments, and features are also claimed and described, including determining and utilizing a reference time on an uplink CC.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive configuration information that indicates a transmission parameter associated with a random access response (RAR) type; transmit a random access message associated with the RAR type; use the transmission parameter to obtain a physical downlink control channel (PDCCH) communication that schedules a physical downlink shared channel (PDSCH) communication that includes a RAR in a medium access control protocol data unit of the PDSCH communication; and obtain or refraining from obtaining the PDSCH communication based at least in part on whether the PDCCH communication is successfully obtained using the transmission parameter. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to the timing arrangements and the transmission gap configurations in 2-step random access channel (RACH) procedures to improve system latency and reliability of a RACH HARQ process are provided. The UE transmits a first message including a random access preamble and a payload, and then monitors for a second message in response to the first message during a random access response (RAR) window. In response to determining that no second message is received by the UE from the BS or a back off indicator is received within the RAR window, the UE re-transmits the preamble and payload of the first message after the RAR window lapses. In response to determining if the second message received within the RAR window carries a FallbackRAR or SuccessRAR, the UE then determines to re-transmit the payload of the first message based on the FallbackRAR, or to transmit an acknowledgement message based on the SuccessRAR.

Abstract: In some implementations, a method of wireless communication includes receiving, at a user equipment (UE) from a base station, a downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH). The PDSCH includes a first transmission occasion and a second transmission occasion following the first transmission occasion during a single slot. The method further includes determining, at the UE, an overall processing time following a last symbol of the PDSCH.
