Abstract: Certain aspects of the present disclosure relate to methods and apparatus for resource allocation for physical uplink control channel (PUCCH) used to carry uplink control information (UCI). Certain aspects provide a method for wireless communication by a user equipment. The method generally includes receiving downlink control information (DCI) comprising one or more resource indicator (RI) bits configured to indicate to the user equipment a subset of resources available for transmitting UCI in a PUCCH transmission, wherein the DCI is received on one or more resources of a first physical downlink control channel (PDCCH) transmission. The method further includes identifying resources within the subset indicated by the RI bits to transmit the UCI based on an implicit mapping of PDCCH resources to PUCCH resources and the one or more resources of the first PDCCH transmission. The method further includes transmitting the UCI using the identified resources.

Abstract: Certain aspects of the present disclosure provide techniques for determining and utilizing resources for communicating an acknowledgment message (ACK). In certain aspects, a method generally includes determining a number of bits to utilize for communicating an acknowledgement (ACK) for a data transmission on a physical downlink shared channel (PDSCH). The method further includes determining a resource on a physical uplink control channel (PUCCH) to utilize for communicating the ACK based on the number of bits. The method further includes communicating the ACK on the resource.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to reference signal design for Pi/2-binary phase shift keying (Pi/2-BPSK) modulation with frequency domain spectral shaping (FDSS). In certain aspects, a method includes generating a set of Gold sequences each having a length and adjusting the length of each of the Gold sequences in the set of Gold sequences. The method also includes applying a phase rotation to each of the Gold sequences in the set of Gold sequences and modulating each of the Gold sequences in the set of Gold sequences by a DFT-s-OFDM with frequency domain spectral shaping (FDSS). The method further includes selecting one or more sequences from the set of modulated Gold sequences based on a parameter and transmitting the one or more sequences to a user equipment (UE) or a base station (BS).

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: Systems, methods, computer-readable medium, and apparatus are disclosed that allow for control information to be provided in an efficient manner during short burst transmission. For example, an apparatus may be configured to receive downlink control information (DCI) that indicates an allocated resource from a base station. The apparatus may also receive data from the base station. The apparatus may generate a cyclically shifted sequence that corresponds to a sequence that is cyclically shifted based on at least one of an ACK or NACK for the received data and a SR. The apparatus may then transmit the cyclically shifted sequence in the allocated resource within one symbol period of a slot of a subframe to the base station. Thus, by transmitting the SR and the ACK/NACK in one symbol, control information for short burst transmissions can be provided in a more temporally efficient manner without adding excessive complexity to the UE.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to a physical uplink control channel (PUCCH) sequence design. In some cases, a UE receives (from a network entity, such as a base station/gNB) signaling indicating a base sequence from a set of base sequences available for use in sending one or more bits of uplink control information (UCI) within a transmission time interval (TTI), receives signaling indicating a set of feasible cyclic shifts, selects one of the cyclic shifts based on a value of the one or more bits of UCI, and transmits the UCI using the base sequence and the selected cyclic shift.

In an aspect, a method includes receiving, by a user equipment (UE), hopping information for two consecutive symbols, generating, by the UE, a first symbol of the two consecutive symbols using a format, generating, by the UE, a second symbol of the two consecutive symbols based on the format and the hopping information, and transmitting, by the UE, the two consecutive symbols in an uplink signal.

Abstract: A method and apparatus for improved transmission of ACK and NACK bits to a base station The example method may determine a distance between a first UE and a second UE based on one or more of a sequence length, a number of hypothesis, or a number of UEs sharing an OFDM symbol. The example method may determine a plurality of cyclic shifts for each of the first UE and the second UE. The example method may assign one or more sequences to each UE. The example method may receive, at the base station, a multiplexed signal, wherein the multiplexed signal includes at least one bit of uplink control information (UCI) from the first UE and the second UE multiplexed on an uplink short burst transmitted via the OFDM symbol. The method may enable the receipt of UCI from multiple UEs in a multiplexed signal.

Abstract: A method and apparatus for enabling an UE to selecting acknowledgement/non-acknowledgement (ACK/NACK) resources from a subset of a gNB resource pool. The example method may receive, from an gNB, a radio resource control (RRC) configuration indicating a UE-specific resource set that is a subset of a gNB resource pool. The UE may determine one or more ACK/NACK resources from the UE-specific resource set for an upcoming physical uplink control channel (PUCCH). In some aspects, the UE may determine the one or more ACK/NACK resources based on receiving, from the gNB, a physical downlink control channel (PDCCH) including a corresponding ACK/NACK resource configuration. In other aspects, the RRC may contain multiple resource subsets and the UE may determine the one or more ACK/NACK resources based on determining a size of a payload for a UCI to be transmitted on the PUCCH. The aspects may thus enable dynamic ACK/NACK resource allocation.

Abstract: Aspects described herein relate to communicating feedback in wireless communications. A user equipment (UE) can receive, in a downlink portion of a slot, data communications from a base station, where the data communications comprise multiple code blocks received in one or more downlink symbols. The UE can generate one or more feedback bits to provide feedback for the multiple code blocks. The UE can transmit, to the base station and in an uplink portion of the slot, an indication of the one or more feedback bits
