Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to transmitting uplink control information (UCI) in a short duration. In certain aspects a method includes identifying resources, within an uplink short burst (ULSB) region within a transmission time interval (TTI), for transmitting at least a portion of uplink control information (UCI), the UCI including at least one of one scheduling request (SR) bit and one or more acknowledgment (ACK) bits for acknowledging or negatively acknowledging downlink transmissions. In certain aspects, the method also includes transmitting the UCI using the identified resources.

Abstract: A user equipment (UE) may be configured to receive configuration information from a base station, and the configuration information may indicate at least two different random access channel (RACH) request configuration parameters that each is associated with a respective radio resource control (RRC) state. The UE may be further configured to generate a first message associated with a two-step RACH procedure including a preamble and a payload, the payload including data on an uplink data channel and at least one reference signal. The UE may be further configured to transmit the first message to the base station using at least one of the at least two different RACH request configuration parameters that corresponds to an RRC state of the UE. The preamble may be transmitted on a first set of resources associated with a RACH occasion, and the payload may be transmitted on a second set of resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment determine that a physical uplink shared channel (PUSCH) communication, scheduled by an uplink grant, and a physical uplink control channel (PUCCH) communication, corresponding to a physical downlink shared channel (PDSCH) communication scheduled by a downlink grant, are scheduled to overlap in one or more symbols; determine a threshold time based at least in part on an earliest scheduled starting time of the PUSCH communication or the PUCCH communication; selectively multiplex the PUSCH communication and the PUCCH communication based at least in part on whether the uplink grant, the downlink grant, and the PDSCH communication are received before the threshold time; and transmit the PUSCH communication, the PUCCH communication, or both the PUSCH communication and the PUCCH communication based at least in part on the selective multiplexing. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a set of physical uplink control channel (PUCCH) resources to be used to transmit a channel state information (CSI) payload based at least in part on a first rank that is independent of a second rank used to construct the CSI payload; and transmit the CSI payload, to a base station (BS), using one or more resources from the set of PUCCH resources. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor for a first transmission of a first service type (e.g., enhanced mobile broadband (eMBB)) and a second transmission of a second service type (e.g., ultra-reliable low-latency communication (URLLC)). The UE may identify a feedback codebook size for the first service type. The UE may multiplex a first feedback codebook having the identified feedback codebook size and generated for the first transmission with a second feedback codebook generated for the second transmission. Multiplexing the first and second feedback codebooks may produce a multiplexed feedback codebook. In some cases, the UE may perform the multiplexing based on a feedback multiplexing condition being satisfied. The UE may transmit the multiplexed feedback codebook in a control channel (e.g., a physical uplink control channel (PUCCH)) or a shared data channel (e.g., a physical uplink shared channel (PUSCH)).

Abstract: Certain aspects of the present disclosure provide techniques for processing reference and data signals for uplink transmission. A method is provided for wireless communications. The method generally includes obtaining different sets of samples for at least one of: a data signal or a reference signal; spreading the different sets of samples for the at least one data signal or reference signal using separate discrete Fourier transform (DFT) processing blocks; interlacing the spreaded sets of samples by assigning the spreaded sets of samples from each of the separate DFT processing blocks to equally spaced tones; and transmitting the at least one data signal or reference signal on the assigned tones in an orthogonal frequency division multiplexed (OFDM) symbol.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems (e.g., new radio (NR) wireless communications systems), a base station may serve a large number of user equipment (UEs). The base station may allocate uplink control channel resources to the UEs using a limited number of bits by implementing explicit and implicit resource mapping. Explicit mapping may involve determining certain indicated resources based on a received set of bits, and implicit mapping may involve determining a resource indication from a characteristic of a transmission (e.g., a starting control channel element (CCE) for a downlink control information (DCI) transmission). A UE may determine an allocated uplink control channel resource for transmission based on the combination of the two types of indications. Additionally, the UE may implement one or more techniques for handling colliding resource allocations (e.g., acknowledgement (ACK), channel quality indicator (CQI), or scheduling request (SR) resource allocations).

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. In some aspects, the UE may apply the TPC in association with transmitting an uplink communication, wherein a time gap between receiving the group power control DCI and applying the TPC command is based at least in part on a capability value associated with the UE, or a delay value signaled to the UE. Numerous other aspects are provided.

Abstract: Various aspects directed towards generating a reference signal for pi/2-binary phase shift keying (BPSK) modulation are disclosed. In an example, a pi/2-BPSK sequence is selected from a plurality of candidate sequences. A reference signal is then generated based on the selected pi/2-BPSK sequence such that the reference signal is associated with a transmission of data modulated according to a π/2-BPSK modulation.
