Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for wireless energy transfer. A network entity may obtain a report indicative of a capability of a UE to transmit an energy transfer signal on at least one of a downlink band of an FDD configuration or at least one of a downlink symbol or a downlink slot of a TDD configuration, and output at least one of the TDD configuration or the FDD configuration for the energy transfer signal. The TDD configuration may include the at least one of the downlink symbol or the downlink slot and the FDD configuration may include the downlink band. The UE may receive the configuration for downlink resources in at least one of time or frequency and transmit an energy transfer signal on one or more of the downlink resources.

Abstract: A method for wireless communication performed by a first sidelink user equipment (UE) includes receiving, from a network entity, a sidelink grant allocating sidelink resources for communicating with a second sidelink UE. The method also includes transmitting, to the network entity via uplink resources, a feedback message based on whether one or both of a first sidelink packet condition or a second sidelink packet condition are satisfied. The method further includes transmitting, to the second sidelink UE via the sidelink resources, a sidelink packet based on both the first sidelink packet condition and the second sidelink packet being satisfied.

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: 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.
