Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a first downlink control information (DCI) message from a base station on a first downlink control channel. The first DCI message may indicate a first set of transmission parameters. The UE may transmit a first uplink control information (UCI) message to the base station on an uplink control channel based on the first DCI message. The first UCI message may include feedback and a channel state information (CSI) report. The UE may receive a second DCI message from the base station on a second downlink channel based on the first UCI message. The second DCI message may indicate a second set of transmission parameters that are different than the first set of transmission parameters. The UE may communicate with the base station using the second set of transmission parameters indicated by the second DCI message.

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: Methods, systems, and devices for wireless communication are described for defining uplink control channel resources and mapping uplink control channel resources to a user equipment (UE). Approaches described herein include identifying a physical uplink control channel (PUCCH) format to be used for a subsequent PUCCH transmission by the UE, identifying a PUCCH resource mapping rule based at least in part on the PUCCH format, and determining an uplink transmission resource to be used for the subsequent PUCCH transmission based at least in part on the PUCCH resource mapping rule. The PUCCH resource mapping rule may be explicit and/or implicit.

Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or base station. The apparatus can determine a first orthogonal matrix and a second orthogonal matrix, the first orthogonal matrix including a size of M×N1 with M×N1 rows and M×N1 columns, the second orthogonal matrix including a size of M×N2 with M×N2 rows and M×N2 columns. The apparatus can also determine a first codebook based on the first orthogonal matrix and a second codebook based on the second orthogonal matrix, the first codebook and the second codebook including a plurality of codepoints. Also, the apparatus can transmit a first signal and a second signal, the first signal including a first codepoint of the plurality of codepoints in the first codebook, the second signal including a second codepoint of the plurality of codepoints in the second codebook.

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. A UE may receive, from the base station, a first resource assignment for a first set of symbols. The UE may also receive, from the base station, a second resource assignment for a second set of symbols, where the first set of symbols and the second set of symbols include an overlapping set of symbols. The UE may modify first resources for the first resource assignment, second resources for the second resource assignment, or both. The UE may then transmit first information based on the first resource assignment.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, while the UE is using a first modulation order for a physical uplink control channel, a signaling message that identifies a second modulation order, for the physical uplink control channel. The UE may provide the physical uplink control channel using the second modulation order. In some aspects, a base station may provide, while a UE is using a first modulation order for a physical uplink control channel, a signaling message that identifies a second modulation order, for the physical uplink control channel. The base station may receive the physical uplink control channel using the second modulation order. Numerous other aspects are provided.

Abstract: Aspects described herein relate to determining a beta offset for determining a number of shared channel resources to be used to transmit uplink control information, where a downlink control information indicating a resource grant for the shared channel resources does not include at least an indication of selection of a dynamic beta offset. A shared data channel including the uplink control information can be generated based at least in part on the beta offset, and transmitted over the shared data channel resources.

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.
