Abstract: A UE may transmit, to a base station, and the base station may receive, from the UE, a turbo HARQ-ACK message corresponding to a first downlink transmission. The turbo HARQ-ACK message may include an indication of a duplexing mode associated with a second downlink transmission. The base station may transmit, to the UE, and the UE may receive, from the base station, the second downlink transmission based on the indication of the duplexing mode. The indication of the duplexing mode may correspond to a full-duplex mode or a half-duplex mode. The first downlink transmission may correspond to a first TB. The second downlink transmission may correspond to a second TB. The turbo HARQ-ACK message may further indicate a requested delta MCS for the second downlink transmission with respect to an MCS associated with the first downlink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A first device may obtain information indicative of a configuration to provide code block group (CBG)-based feedback for one or more semi-persistent scheduling (SPS) communications scheduled for the first device. The first device may then monitor for the one or more SPS communications in one or more CBGs of a TB in accordance with one or more SPS communication configurations. Based on the monitoring of the semi-persistent scheduling communications, the first device may generate one or more feedback bits associated with the one or more SPS communications, and may communicate, with a second device, the one or more feedback bits associated with the one or more SPS communications in accordance with the configuration to provide CBG-based feedback.

Abstract: A method in accordance with aspects of the disclosure comprises receiving a plurality of downlink control information (DCI) signals, wherein each DCI signal is associated with a Demodulation Reference Signal (DMRS) Port Group (DMRS-PG) of a plurality of DMRS-PGs, and each DCI signal within the plurality of DCI signals contains a DMRS-PG Identifier (DMRS-PGID) identifying the associated DMRS-PG, performing one or more measurements associated with the each DCI signal, and generating a multi-port-group uplink control information (UCI) signal based on the one or more measurements associated with the each DCI, wherein the multi-port-group UCI signal contains an indication of whether the each DCI is successfully received. The indication can be explicitly contained in the UCI, or implicitly realized using scrambling sequences associated with DMRS-PGs to scramble the UCI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an uplink grant that indicates scheduling information for an uplink shared channel transmission by the UE. The UE may also receive a downlink grant scheduling feedback information to be piggybacked on the uplink shared channel transmission, and may determine whether the downlink grant has been received after the uplink grant. The UE may then select from a set of resources indicated in the uplink grant, or determine that a feedback piggybacking condition has been met based on the downlink grant. The UE may perform the uplink shared channel transmission to the base station, in some cases including the feedback information.

Abstract: Wireless communications systems and methods related to semi-persistent scheduling (SPS) occasion cancellation or validation are provided. A base station (BS) transmits an SPS configuration to a UE indicating a plurality of SPS occasions. The BS further transmits to the UE a mode indication indicating an occasion-identification mode, the occasion-identification mode indicating whether one or more occasion-identification parameters identify one or more SPS occasions of the plurality of SPS occasions to be cancelled or to be used for transmission. The BS further transmits to the UE the one or more occasion-identification parameters. The BS performs SPS transmission based on the mode indication and the one or more occasion-identification parameters.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to maintain phase coherence for repetitions of uplink channel transmissions across slot boundaries. One example method includes receiving, from a network entity, phase coherence configuration information indicating that the UE is to maintain phase coherence for repetitions of uplink channel transmissions that cross slot boundaries; receiving scheduling information scheduling a plurality of repetitions of an uplink channel transmission; determining, based on the scheduling information, that the scheduled plurality of repetitions of the uplink channel transmission will cross one or more slot boundaries; and transmitting the plurality of repetitions of the uplink channel transmission based on the scheduling information and the phase coherence configuration information.

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 one or more control messages that collectively schedule three or more physical uplink control channels (PUCCHs) involving at least two scheduling overlaps, at least one of the three or more PUCCHs with repetition across multiple transmission time intervals (TTIs). The UE and the network entity may perform a conflict resolution procedure to resolve the two or more scheduling overlaps, the conflict resolution procedure based on an order for resolving scheduling overlaps between the three or more PUCCHs. The UE may transmit, to the network entity, a resolved set of PUCCHs from the from the three or more PUCCHs based on the conflict resolution procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station (BS), a UE capability indicator of a capability of the UE. The BS may select an uplink switch mode. The UE may receive, from the BS, signaling identifying the uplink switch mode, of a plurality of uplink switch modes, for switching one or more transmit chains of the UE between a first uplink duplex configuration and a second uplink duplex configuration. The UE may switch at least one uplink duplex configuration of at least one transmit chain of the UE based at least in part on the uplink switch mode. Numerous other aspects are provided.
