Abstract: Certain aspects of the present disclosure provide techniques for enabling mini-slot detection in sidelink. A method performed by a user equipment (UE) includes receiving a sidelink configuration comprising a set of configuration parameters. The set of configuration parameters defines a plurality of sidelink mini-slots within a slot structure. The method may further include performing communications in one or more of the plurality of sidelink mini-slots.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit acknowledgment feedback for a combined signal derived from individual downlink signals received on respective radio links, where the acknowledgment feedback is transmitted with a phase shift applied to the transmission. In some cases, the phase shift may indicate which individual downlink signals were unsuccessfully received and decoded on the respective radio links. For example, the acknowledgment feedback message may include acknowledgment feedback for a final decoding of the combined signal on whether the combined signal is successfully received and decoded and side negative acknowledgment information indicating which individual radio links were unsuccessfully received and decoded via the phase shift. The UE may transmit the acknowledgment feedback on a strongest radio link, a subset of the radio links, or on all of the radio links.

Abstract: Aspects relate to techniques for signaling the capability of a wireless communication device (e.g., a UE) to support demodulation reference signal (DMRS) bundling for channel estimation across two or more slots in the sidelink or uplink. In some examples, a transmitting UE may transmit a DMRS bundling indication to a receiving device (e.g., a receiving UE for sidelink DMRS bundling or a base station for uplink DMRS bundling). The DMRS bundling indication may indicate a capability of the transmitting UE to support DMRS bundling. The transmitting UE may then transmit a respective set of DMRSs within each of two or more slots during a DMRS bundling window to the receiving device based on the transmitting wireless communication device and the receiving device supporting DMRS bundling.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a measurement report indicating a set of channel quality indicators for a set of candidate beams; determine that a downlink transmission from a base station is not received via one or more beams of the set of candidate beams; and transmit a negative acknowledgement for the downlink transmission via one or more new beams of the set of candidate beams. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may receive an indication that a transmission of first data is to be modified and that second data is to be transmitted in place of a portion of the transmission of the first data; and identify a single time at which the transmission of the first data is to be canceled and transmission of the second data can begin, based at least in part on capabilities of the UE. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from an entity of a non-terrestrial network (NTN), a system information block (SIB) that indicates information relating to one or more NTN SIBs that are to include at least one of ephemeris information or feeder link timing advance information. The UE may receive, from the entity of the NTN, the one or more NTN SIBs based at least in part on the information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a user equipment (UE) may receive, from a base station, a physical downlink control channel (PDCCH) indicating a configuration for one or more of demodulation reference signal (DMRS) bundling that is to be used for channel estimation by the base station for a first group of physical uplink control channels (PUCCHs) or frequency hopping for a second group of PUCCHs. The apparatus may transmit, to the base station, one or more PUCCHs based at least in part on the configuration. Numerous other aspects are described.

Abstract: Aspects are provided for HARQ feedback and retransmission procedures for cooperative relaying in sidelink networks. A relay attempts to decode sidelink data received from a source for relay to a destination. The relay may combine LLRs for the sidelink data and for a retransmission of the sidelink data. The relay determines a resource of a wireless channel for transmitting feedback to the source in response to the decoding attempt. If decoding is successful, the relay transmits the data to the destination. The destination then attempts to decode the data received from the relay. The destination may combine LLRs for the data and for a retransmission of the data. The destination determines a resource of a wireless channel for transmitting feedback to the relay in response to the decoding attempt. The resources are based on a relay identifier associated with the relay.
