Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an uplink grant that schedules uplink shared channel transmissions of a first length. The UE may then determine the actual lengths of the transmissions, which may differ from each other and the scheduled length (e.g., due to conditions of the communication environment, such as the location of slot boundaries). The UE may also identify uplink control information to be multiplexed on the uplink shared channel (e.g., when the scheduled transmission overlaps with a control channel or based on an uplink grant for the uplink control information). The UE may multiplex the uplink control information on the uplink shared channel so as to maintain the same rate-matching scheme and the same coding scheme for each of the transmissions, and transmit the uplink control information in at least one of the transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for configuring group indices for uplink transmissions from a user equipment (UE) such that the UE may be able to determine whether to combine uplink transmissions scheduled on overlapping time resources. Specifically, the UE may combine uplink transmissions associated with a same group index for transmission in a single channel, and the UE may avoid combining uplink transmissions associated with different group indices. In some cases, the indication of a group index associated with an uplink transmission from a UE may be explicit (e.g., provided in a downlink control information (DCI) message), and, in other cases, the indication of a group index associated with an uplink transmission from a UE may be implicit (e.g., corresponding to a resource allocated for the uplink transmission).

Abstract: A design is provided for spatially multiplexing uplink channels. A user equipment (UE) detects that a Physical Uplink Control Channel (PUCCH) and a Sounding Reference Signal (SRS) are to be transmitted simultaneously. The UE decides to spatially multiplex the PUCCH and the SRS for simultaneous transmission via different sets of one or more antennas. The UE determines time and frequency resources for the PUCCH and the SRS to avoid collision of at least a portion of the PUCCH with the SRS. The UE transmits the spatially multiplexed PUCCH and SRS using the determined time and frequency resources.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for Type 3 HARQ-ACK codebook enhancements for URLLC. A UE may receive a configuration for reporting HARQ-ACK feedback for a subset of HARQ process IDs included in a set of HARQ process IDs. The set of HARQ process IDs may be associated with a Type 3 HARQ-ACK codebook. The subset of HARQ process IDs may be associated with a modified Type 3 HARQ-ACK codebook that is smaller than the Type 3 HARQ-ACK codebook. The UE may receive, based on the configuration, a trigger for the modified Type 3 HARQ-ACK codebook and report, based on the trigger, the modified Type 3 HARQ-ACK codebook including the HARQ-ACK feedback for the subset of HARQ process IDs.

Abstract: A UE may identify slots to transmit and/or receive information related to one or more HARQ processes in frame structure that includes both sub-band full duplex slot types and time division duplex slot types. Based on a first slot used for control information, a UE can identify a second slot for PUSCH or PDSCH communication based on an offset between the first slot and the second determined by calculating slot offsets (e.g., based on parameters received from a base station). In some aspects, a UE may exclude certain slot duplex types (e.g., SBFD or TDD) when calculating slot offsets. In some aspects, a UE may calculate slot offsets differently for different HARQ processes corresponding to one frame. In some aspects, slot offset behaviors may be based on priority of information associated with a HARQ process.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. Because the local antennas and auxiliary antennas may have different capabilities (e.g., due to different power or other constraints), the first device may generate first uplink signals for transmission using the local antennas differently from second uplink signals for transmission using the auxiliary antennas. The first device may transmit the first uplink signals to the base station using the local antennas and transmit the second uplink signals to the second device for transmission to the base station using the auxiliary antennas based on different configurations.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a payload for inclusion in an uplink transmission. The UE may organize the payload into a code block group (CBG) that includes one or more code blocks (CB). The UE may map each CB of the CBG to a corresponding uplink shared channel resource unit (e.g., a physical uplink shared channel resource unit) of an uplink transmission occasion of the first UE. The uplink transmission occasion may also be shared with one or more additional UEs such that the CBG of the first UE is multiplexed with additional CBGs from the additional UEs. The UE may transmit, to a base station, the uplink transmission including each uplink shared channel resource unit on which the CBG is organized.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive configuration signaling indicating a parameter for generating a plurality of first orthogonal matrices, wherein the plurality of first orthogonal matrices are based at least in part on a second orthogonal matrix, and wherein a size of the second orthogonal matrix is based at least in part on a number of one or more time periods configured for conveying a payload and a number of one or more frequency tones configured for conveying the payload. The UE may generate a plurality of codebooks corresponding to the plurality of first orthogonal matrices. The UE may transmit a first portion the payload using a first sequence from a first codebook of the plurality of codebooks and a second portion of the payload using a second codebook of the plurality of codebooks.
