Abstract: Methods, systems, and devices for wireless communication are described. A network node may transmit a first message using a first transmit power based on a first set of values corresponding to a set of power control parameters. The set of power control parameters may include an accumulated transmit power control parameter. The network node may receive a second message including information indicative of at least one of a second set of values corresponding to the set of power control parameters. The network node may transmit a third message using a second transmit power based on a value corresponding to the accumulated transmit power control parameter. The value may correspond to the accumulated transmit power control parameter, which may be based on a first difference between one or more of the first set of values from before the second message and one or more of the second set of values.

Abstract: This disclosure provides systems, methods, and apparatuses for sharing a maximum transmit power limit between a first radio access technology (RAT) and a second RAT. In one aspect, a wireless communication apparatus may reduce the maximum transmit power limit of a first uplink signal associated with the first RAT to obtain a first transmit power. The wireless communication apparatus may allocate a second transmit power remaining from the maximum transmit power limit to a second uplink signal associated with the second RAT. The wireless communication apparatus may reduce the maximum transmit power limit when the wireless communication apparatus is located at a cell edge, and a higher priority of the first RAT in relation to the second RAT may otherwise result in the second transmit power of the second uplink signal not satisfying a threshold.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a transmitting device may perform a pre-distortion of a signal on a resource allocation for the signal and using discrete Fourier transform (DFT)-domain processing. For example, the transmitting device may perform a first frequency-domain (FD) to time-domain (TD) transform, which may be an example of an inverse DFT (IDFT), on a first set of FD symbols to obtain a first set of TD samples. A size of the first FD to TD transform may be based on the resource allocation for the signal. The transmitting device may perform a crest factor reduction (CFR) function on the first set of TD samples to pre-distort the signal in the TD (e.g., in the IDFT domain), which may enable the transmitting device to avoid out-of-band (OOB) emission or otherwise have greater control over where the pre-distortion contributes energy.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit a sounding reference signal (SRS) to a base station using an SRS antenna switch (SRS-AS) or an SRS carrier switch (SRS-CS) transmission technique and the UE may feature multiple antenna groups that have separate exposure budgets due to their spatial separation. The UE may employ one or more accounting procedures for tracking energy contributions associated with the SRS across the multiple antenna groups of the UE and may employ one or more power control procedures for setting a transmit power for an uplink signal in accordance with the energy contributions associated with the SRS.

Abstract: Aspects of the disclosure relate to the determination of an available slot for a triggered aperiodic sounding reference signal (A-SRS) resource set when a triggering downlink control information (triggering DCI) indicates a DCI code point that is not configured for that A-SRS resource set. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, apparatuses, and computer-readable storage medium for rate matching for TBoMS are provided. An example method includes calculating a slot length for each UL slot of a plurality of UL slots, the slot length for each UL slot being associated with a plurality of rate matching output bits, each UL slot including a starting point for the plurality of rate matching output bits, the slot length for each UL slot being associated with a starting boundary, the plurality of UL slots being associated with at least one of a single TB or a single rate matching. The example method may include allocating one or more bits of the plurality of rate matching output bits for a modulation process. The example method may include refraining allocating at least one bit of the plurality of rate matching output bits for the modulation process, the at least one bit corresponding to UCI multiplexing.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information identifying a resource allocation for an uplink transmission of a transport block over multiple slots. The UE may transmit, to the base station, at least a portion of coded bits corresponding to the transport block based at least in part on a different uplink transmission being scheduled within the uplink transmission of the transport block over the multiple slots. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE receives, from a network entity, after transmitting at least a first repetition of a physical uplink control channel (PUCCH) transmission according to a first repetition factor, a dynamic indication of a second repetition factor to apply for transmitting the same PUCCH transmission. The UE determines an application time of the second repetition factor based on at least a timing of a last complete or partial transmission instance of the PUCCH transmission. The UE transmits, to the network entity, one or more additional repetitions of the PUCCH transmission based, at least in part, on the determined application time of the second repetition factor.
