    Abstract: A user equipment maps a high priority hybrid automatic repeat request-acknowledgment/negative acknowledgment (HARQ-ACK/NACK) information to one or more resource elements (REs), and maps one or more of a low priority HARQ-ACK/NACK information, channel state information (CSI), or uplink-shared channel (UL-SCH) data to REs while rate matching around the mapped high priority HARQ-ACK/NACK REs. A network entity receives an uplink transmission, including high and low priority HARQ-ACK/NACK information, CSI, and UL-SCH data mapped to high and low priority HARQ-ACK/NACK REs, CSI REs. and UL-SCH REs, respectively. The low priority HARQ-ACK/NACK REs, the CSI REs, and the UL-SCH REs are rate matched around the high priority HARQ-ACK/N ACK REs. The network entity demaps and decodes the REs of the high and low priority HARQ-ACK/NACK, the CSI, and UL-SCH to obtain the high and low priority HARQ-ACK/NACK information, CSI, and UL-SCH data.

    Abstract: Aspects of the present disclosure allow a base station to simultaneously send SSBs to a UE and to associate different ROs or designated subsets of preambles with the simultaneously transmitted SSBs. The base station may configure a time or frequency offset for different ROs, or a number of preamble cyclic shifts associated with the SSBs. The base station then simultaneously sends a plurality of SSBs to the UE, where each of the SSBs is associated with a different beam, and where each of the SSBs is associated with a different RO or a designated subset of preambles. After the UE simultaneously obtains the SSBs from the base station, the UE may determine the offset for one of the different ROs, or the number of preamble cyclic shifts associated with one of the SSBs. The UE may then send a preamble to the base station in response to the determination.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication to switch from a first transmission configuration indicator (TCI) state associated with a first cell to a second TCI state associated with a second cell. The UE may apply the second TCI state, including switching from a first bandwidth part (BWP) associated with the first cell to a second BWP associated with the second cell. For example, the UE may receive an indication to switch from the first BWP to the second BWP. Additionally, or alternatively, the UE may determine to switch from the first BWP to the second BWP based at least in part on the indication to switch from the first TCI state to the second TCI state. Numerous other aspects are described.

    Abstract: Certain aspects of the present disclosure provide techniques for finite field parity for a hybrid automatic repeat request (HARQ) codebook. A method that may be performed by a base station (BS) includes indicating, to a user equipment (UE), a codebook for uplink transmission of HARQ feedback, the codebook based on: (i) a number (M) of candidate downlink transmission occasions for a time period, and (ii) a maximum number (k) of downlink transmissions the UE can receive during the time period. The method also includes selecting an action to perform based on a set of codepoints of the codebook, the set of codepoints comprising: (i) a first combination of codepoints, and (ii) a second combination of codepoints different from the first combination, wherein HARQ feedback calculated from the first combination is equal to HARQ feedback calculated from the second combination.

    Abstract: Aspects relate to mechanisms for wireless communication devices to environmental sensing with the assistance of a network. A UE transmits an increase transmission power request message to a base station. The UE receives an increase transmission power acceptance message from the base station in response to transmitting the increase transmission power request message. The UE transmits a transmission using an increased transmission power for reflection by at least one object based on the increase transmission power acceptance message. The UE receives a reflection of the transmission reflected off the at least one object. The UE determines at least one parameter associated with the object based on the reflection of the transmission reflected off the at least one object.

    Abstract: An apparatus may be configured to communicate at least one pilot signal with another apparatus according to a first configuration, at least one of a lower frequency density or a higher time density being indicated by the first configuration than a second configuration for a type of pilot signal that includes the at least one pilot signal. The apparatus may be further configured to communicate with the other apparatus based on the at least one pilot signal. Another apparatus may be configured to receive, from a base station, spatial relationship information or transmission configuration indicator (TCI) state information corresponding to a directional beam at the UE for communication on a channel. The apparatus may be further configured to apply the directional beam for communication with the base station on another channel in a sub-6 gigahertz (GHz) frequency band.
