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.

Abstract: Aspects are provided which allow a base station to indicate use of a mini-slot based resource allocation in sidelink communications between a Tx UE and a Rx UE. Initially, the base station configures control information indicating a sidelink data resource for a mini-slot, and transmits the control information to a Tx UE. After the Tx UE receives the control information, the Tx UE transmits sidelink data in the sidelink data resource to a Rx UE. Similarly, the Rx UE receives the control information from either the Tx UE or the base station, and the Rx UE receives the sidelink data in the sidelink data resource from the Tx UE. Accordingly, the base station may schedule the Tx UE and Rx UE to communicate sidelink data in mini-slots rather than slots, thereby reducing scheduling latency, increasing the number of available resources, and achieving more flexibility in sidelink communications.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for sidelink feedback power control. The UE may transmit a sidelink feedback transmission, in accordance with the configuration, using a transmit power that is based at least in part on at least one of: a quantity of resource blocks (RBs) associated with the sidelink feedback transmission, a quantity of symbols associated with the sidelink feedback transmission, a sidelink pathloss value, or a size of the sidelink feedback transmission. 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 downlink control information including a sidelink cancellation indication indicating a cancellation of a communication in a communication resource that has an overlap with a physical sidelink control channel. The UE may transmit on the communication resource in accordance with the sidelink cancellation indication and a rule associated with the overlap with the physical sidelink control channel. Numerous other aspects are described.

Abstract: Methods, apparatuses, and computer-readable medium for soft cancellation of sidelink transmissions are provided. An example method may include receiving, from a base station, DCI comprising at least one of: an open loop power control parameter, a maximum transmit power, or a closed loop power control parameter. The open loop power control parameter, the maximum transmit power, or the closed loop power control parameter may be associated with a PSSCH or a PSCCH. The example method may further include reducing a transmit power of a scheduled transmission associated with the PSSCH or the PSCCH to a reduced transmit power if the reduced transmit power is above a threshold or cancel the scheduled transmission if the reduced transmit power is below the threshold. The reduced transmit power may be based on the open loop power control parameter, the maximum transmit power, or the closed loop power control parameter.

Abstract: Aspects presented herein may enable a UE to multiplex an SCI-exclusive message with a data-exclusive message/traffic. In one aspect, a first UE multiplexes SCI with a PSSCH in a slot, the SCI being associated with a control message and the PSSCH being associated with a data message, and the SCI including an indication that the SCI and the PSSCH are decoupled in the slot. The first UE transmits, to a second UE, the SCI and the PSSCH in the slot. In another aspect, a second UE receives, from a first UE, SCI and a PSSCH in a slot, the SCI being associated with a control message and the PSSCH being associated with a data message, and the SCI including an indication that the SCI and the PSSCH are decoupled in the slot. The second UE decodes the data message based at least in part on the indication.

Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a user equipment (UE) may include performing a clear channel assessment (CCA), transmitting, to a first UE based on the CCA being successful, a first transport block (TB) via a first sub-PSSCH associated with a first sub-slot, and transmitting, to at least one of the first UE or a second UE, a second TB via a PSSCH associated with a slot.

Abstract: Aspects relate to techniques for enhancing sidelink scheduling information to include a priority assigned to a sidelink transmission. For example, a transmitting wireless communication device may receive sidelink scheduling information scheduling a sidelink transmission from a transmitting wireless communication device to a receiving wireless communication device. The sidelink scheduling information may further include a priority indicator associated with the sidelink transmission. The transmitting wireless communication device may then transmit the sidelink transmission to the receiving wireless communication device based on the scheduling information. The priority indicator may further facilitate hybrid automatic repeat request (HARQ) codebook construction on the sidelink and uplink for the transmission of acknowledgement information of the sidelink transmission.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a user equipment (UE) and a base station. The UE receives a configuration for a plurality of semi-persistent scheduling (SPS) occasions each SPS occasion including multiple opportunities for a downlink transmission by a base station. The UE monitors for the downlink transmission during one or more opportunities of an SPS occasion. The base station transmits a packet to the UE in an opportunity of an SPS occasion based on an arrival time of the packet. In various configurations, a base station may transmit first information via a first communication opportunity and second information via a second communication opportunity of that same SPS occasion. A wireless communication device may monitor all communication opportunities of an SPS occasion to decode the information sent in two or more of the communication opportunities of the SPS occasion.

Abstract: A first UE may select, based on a resource pool configuration for a sidelink communication, at least one of a first slot in time or a second slot in time of a plurality of slots. The plurality of slots may be associated with DMRS bundling. The first UE may configure, based on the DMRS bundling, at least one of one or more symbols in the first slot in time from a gap symbol to a non-gap symbol or one or more symbols in the second slot in time from an AGC symbol to a non-AGC symbol. The first UE may transmit, to a second UE, an indication of the configuration of the at least one of the one or more symbols in the first slot in time or the one or more symbols in the second slot in time.
