Abstract: Aspects of the present disclosure provide a scheduling entity in communication with a set of scheduled entities within a wireless communication network. The scheduling entity groups a plurality of tones into uplink clusters, where each uplink cluster includes one or more adjacent tones. In addition, the scheduling entity maps a first set of uplink clusters to a first virtual cluster group (VCG) for an uplink control channel, assigns the first VCG to a first scheduled entity of the set of one or more scheduled entities, provides a first VCG index identifying the first VCG to the first scheduled entity and receives uplink control information from the first scheduled entity on the first VCG over the uplink control channel.

Abstract: Aspects of the disclosure relate to wireless communication systems configured to provide techniques for strategically placing a sounding reference signal (SRS) within a slot to improve the decoding timeline. Aspects of the disclosure further relate to wireless communication systems configured to optimize the physical downlink control channel (PDCCH) search space within a slot to improve the decoding timeline. Features may also include placing the SRS near the end of the slot, such as after the uplink user data traffic and the corresponding uplink demodulation reference signal (DMRS). In addition, features may also include identifying the PDCCH search space within the slot based on at least a slot index of the slot. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, multiple timing advances (TAs) may be configured for non-coherent joint transmission (NCJT) with respective transmit receive points (TRPs). For example, a NCJT mode may have multiple TAs semi-statically configured for the UE to follow for each TRP. In some cases, a TA index corresponding to a TA for a TRP may be added as a field to a sounding reference signal (SRS) resource definition (e.g., SRS resource configuration). Additionally or alternatively, the TA index may be determined from an SRS index transmitted by the TRP, where the TA index corresponds to a TA for uplink information in a physical uplink shared channel. Additionally or alternatively, the TA index may be included as a field in a physical uplink control channel (PUCCH) definition to indicate a TA for a corresponding PUCCH that the UE transmits to the TRP.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a transmit power control (TPC) command, associated with the UE, based at least in part on group power control downlink control information (DCI); and determine a loop index associated with the TPC command, wherein the loop index identifies a power control loop, of a plurality of power control loops, for the TPC command.

Abstract: Techniques are described herein for addressing tone misalignment between signals of a first radio access technology (RAT) and signals of a second RAT in a combined signal. In some wireless communications systems, the tones of uplink (UL) signals may be shifted up or down based on the configuration of the particular RAT. If UL signals of the first RAT are not shifted in frequency and UL signals of the second RAT are shifted in frequency, processing the combined signal may include additional processing to account for the mismatch.

Abstract: A user equipment (UE) may apply transmit power control (TPC) commands and transmit uplink information based on received downlink control information (DCI). A UE may receive multiple DCI messages including multiple TPC commands for an uplink transmission. The power level for the uplink transmission may be adjusted based on the combination of TPC commands. For example, the TPC commands may be considered together (e.g., added, averaged, etc.), the latest TPC command may be used, etc. In some cases, a change in TPC command for an uplink transmission (e.g., from a previous TPC command for the uplink transmission indicated via other DCI) may indicate a change in one or more transmission attributes for the uplink transmission. In some cases, a UE may receive a grant for a prioritized transmission, resulting in discontinuous transmission (DTX) of a previous transmission, which may result in TPC modification by the UE.

Abstract: Certain aspects of the present disclosure provide techniques for uplink control information (UCI) transmission for overlapping physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH) resource assignments with repetition. A method of wireless communication by a user equipment (UE) is provided. The method generally includes receiving scheduling to transmit on the PUSCH in a first one or more slots associated with a first number of repetitions and scheduling to transmit on the PUCCH in a second one or more slots associated with a second number of repetitions. The scheduled transmissions overlap in at least one slot. The method includes determining which channel to transmit UCI on and which channel to drop for each of the first and second one or more slots. The method includes transmitting or dropping the UCI in the first and second one or more slots in accordance with the determination.

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, randomized shifts of a base sequence may be used for transmitting uplink control information. For example, a user equipment (UE) may identify a base sequence of an uplink control message. The UE may also receive signaling that indicates a UE-specific initial shift that may be applied to the base sequence. In some examples, the signaling that indicates the randomized shift may be explicit, implicit, or a combination thereof. After determining one or more shifted sequences based on the UE-specific initial shift, a payload of the uplink control message, and the base sequence, the UE may select a shifted sequence to be transmitted, where the selection is based on a payload of the uplink control message. For example, different shifted sequences may be selected for respective transmissions of scheduling requests, 1-bit acknowledgments (ACKs), 2-bit ACKs, and the like.
