Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a multiple-slot unit structure that is to be used for sidelink communication, the multiple-slot unit structure having multiple contiguous slots that include, in sequence, a first time interval for automatic gain control, a second time interval for at least one of sidelink control communication or sidelink data communication, and a third time interval providing a time gap for transmission-reception switching. The UE may communicate, on a sidelink, in one or more multiple-slot units that are in accordance with the multiple-slot unit structure. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may communicate in an unlicensed spectrum (e.g., a shared radio frequency spectrum band). As such, the UE may determine a codebook size for transmitting hybrid access request (HARQ) acknowledgement (ACK) feedback with respect to the unlicensed spectrum. Accordingly, the UE may base the HARQ ACK codebook size on a number of HARQ processes with which the UE has been configured. Additionally or alternatively, the UE may base the HARQ ACK codebook size on a number and/or duration of downlink channel monitoring occasions indicated by the base station. In some cases, the UE may base the HARQ ACK codebook size on a combination of the techniques described herein.

Abstract: A configuration for transmission control for multi-relay based communication. The apparatus determines a priority of data transmission at each relay of a plurality of relays between the base station and at least one UE. The apparatus transmits a PDSCH comprising control information for the at least one UE and a priority indication instructing each relay of the plurality of relays which data is contained in the PDSCH. The PDSCH may include an indication indicating whether data corresponding to the at least one UE is contained in the PDSCH. The PDSCH may include a field that identifies data and a corresponding UE of the at least one UE that is contained in the PDSCH. The apparatus may transmit, to each relay of the plurality of relays, the priority of data transmission, wherein the priority of data transmission includes a priority for uplink and downlink transmissions.

Abstract: Example aspects include a method, apparatus, and computer-readable medium for wireless communication at user equipment of a mobile network, comprising receiving, from a base station via a first beam, a pre-grant message requesting the UE to perform a listen-before-talk (LBT) procedure on a second beam. The aspects further include performing, according to the pre-grant message, the LBT procedure on the second beam. Additionally, the aspects include indicating, to the base station, whether the LBT procedure was successful.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer-readable medium for transmitting a capability signal to a network entity, wherein the capability signal indicates whether the UE is capable of supporting an uplink (UL) bandwidth that is equal to or less than a downlink (DL) bandwidth for communication over an unlicensed band; and exchanging a signal between the UE and the network entity over the unlicensed band according to the capability signal. Some alternative or additional aspects include methods, apparatuses, and computer-readable medium for receiving a signal from a network entity, wherein the signal indicates that short control signal exemption (SCSt) is applied to a synchronization signal block (SSB) transmission of one or more network entities over an unlicensed band; and skipping SSB presence detection of the one or more network entities in response to the signal.

Abstract: Aspects of the present disclosure provide techniques for using automatic gain control symbols to indicate a sidelink mini-slot. A method performed by a transmitting user equipment includes transmitting, during a first time portion of a symbol within a slot, a first beam associated with a first receiving user equipment. The first time portion of the symbol is configured to indicate that the first receiving user equipment will receive another transmission from the transmitting user equipment during a first mini-slot within the slot associated with the first time portion. The method may further include transmitting, during a second time portion of the symbol within the slot, a second beam associated with a second receiving user equipment. The second time portion of the symbol is configured to indicate that the second receiving user equipment will receive another transmission from the transmitting user equipment during a second mini-slot within the slot.
