Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication. The apparatus applies a processing timeline for multiplexing uplink control information (UCI) in at least one slot of a multiple slot physical uplink shared channel (PUSCH) transmission. The apparatus transmits the multiple slot PUSCH transmission with multiplexed UCI based on the processing timeline being satisfied.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication associated with Type B physical uplink channel repetitions of a transport block. The UE may transmit the repetitions of the transport block, including a first smaller repetition of the repetitions that has a first payload size that is smaller than a nominal payload size for the repetitions and that includes a first self-decodable data portion of the transport block. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communication systems, for example those supporting accumulated feedback, a user equipment (UE) may receive an indication of a plurality of accumulated feedback events that are each representative of different feedback combinations for reporting accumulated feedback for a set of scheduled downlink occasions and may determining the accumulated feedback for the set of scheduled downlink occasions. The UE may select, from the plurality of accumulated feedback events, a representative event based on the accumulated feedback and may transmit an uplink control message indicative of the representative event. In some examples, transmitting the uplink control message may include identifying a Huffman code for the representative event and transmitting the Huffman code via one or more stages of the uplink control message.

Abstract: Methods, systems, and devices for wireless communications are described. A device may receive first control signaling indicating a first codebook configuration associated with a first channel state information reference signal (CSI-RS) antenna port configuration. The device may receive second control signaling indicating a second codebook configuration associated with a second CSI-RS antenna port configuration. The second CSI-RS antenna port configuration includes fewer antenna ports than the first CSI-RS antenna port configuration. The device may perform a channel state information (CSI) measurement based on the first codebook configuration and the second codebook configuration. The device may transmit a CSI report based on the CSI measurement.

Abstract: Methods, systems, and devices for wireless communications are described for cell access techniques in carrier aggregation configurations in which one or more carriers do not provide discovery signals such as synchronization signal block (SSB) transmissions. A UE may be configured with an anchor carrier on which SSBs are transmitted, and one or more non-anchor carriers on which SSBs are not transmitted. A single cell barring indication may be provided for the anchor carrier, in which case the UE may follow cell barring indications for associated non-anchor carriers. In other cases, separate cell barring indications may be provided for one or more anchor carriers and one or more non-anchor carriers.

Abstract: Methods and apparatuses for adaptive subcarrier spacing in wireless communication networks are described. For example, the described aspects include transmitting, from the UE to a network entity, a first PRACH transmission with a first subcarrier spacing; determining, by the UE, that the first PRACH transmission to the network entity is not successful; and transmitting, from the UE, a second PRACH transmission with a second subcarrier spacing in response to determining that the first PRACH transmission is not successful, wherein the first subcarrier spacing is different from the second subcarrier spacing.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request for an on-demand secret key to a network entity, such as if a secret key for a sidelink channel has expired before a refresh timer of the secret key expires. The UE may transmit a request for an update to a secret key associated with a first physical layer channel secured for sidelink communications based on the secret key being expired. The request may include an identifier of the first physical layer channel associated with the secret key. The UE may receive the update to the secret key based transmitting the request. In some cases, the UE may transmit an indication of the update to the secret key to a second UE.

Abstract: Fallback procedures for user equipments (UEs) are described that provide efficient fallback to a four-step random access procedure from a two-step random access procedure. For example, after transmitting a first message of a two-step random access procedure, a UE may start a fallback timer or counter and monitor for a second message of the two-step random access procedure for the duration of the fallback timer or counter. At the expiration of the fallback timer or counter, the UE may fall back to a four-step random access procedure. In some cases, the UE may transmit multiple repetitions of the first message and monitor for responses after transmitting the repetitions or after each repetition. Additionally, or alternatively, the base station may transmit an explicit signal to the UE that may signal to the UE to perform a fallback procedure at a beginning or middle of a random access procedure.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may receive reference signals from another wireless device over a channel between the devices. The wireless device may perform channel estimation based on the reference signals to determine multiple taps. The wireless device may receive a message from the other wireless device indicating one or more taps to be selected to obtain a secret key for encrypting a message. The wireless device may select the taps based on the indication and communicate one or more encrypted messages with the other wireless device. For example, the wireless device may receive encrypted messages, transmit encrypted messages, or both.
