Abstract: Aspects relate techniques for facilitating resumption of a sidelink transmission after cancellation of the sidelink transmission within resources that overlap with an additional transmission. A transmitting wireless communication device may receive control information from a network entity including a cancellation indication indicating overlapping resources between the resources scheduled for the sidelink transmission and resources scheduled for the additional transmission. Based on the cancellation indication, the transmitting wireless communication device may cancel the sidelink transmission within cancelled resources including at least the overlapping resources and transmit the sidelink transmission via remaining resources of the scheduled resources for the sidelink transmission outside of the cancelled resources.

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: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may communicate one or more messages associated with establishing a sidelink communication connection with a set of UEs, including a second UE. The first UE may transmit a message indicating that the first UE has a data transmission to send. The second UE may receive the message and transmit an indication that a first set of resources is allocated to the first UE for the data transmission. In some examples, the second UE may broadcast the indication that the first set of resources is allocated to the first UE. The first UE may transmit the data transmission over the resources based on receiving the indication that the first set of resources is allocated to the first UE. In some examples, the first UE may perform a listen before talk procedure prior to transmitting the data transmission.

Abstract: Some aspects described herein relate to transmitting, to a receiving user equipment (UE), an indication of a fixed size transport block size (TBS) used for a sidelink transmission, and transmitting, to the receiving UE and based at least in part on the fixed size TBS, the sidelink transmission over sidelink resources. Other aspects relate to the receiving UE receiving the indication and the sidelink transmission. Additional aspects relate to a base station for configuring the sidelink resources for fixed size TBS.

Abstract: Techniques for wireless communications are described. A user equipment (UE) may receive downlink control information (DCI) scheduling sidelink transmissions in one or more sets of multiple transmission time intervals (TTIs) over a shared spectrum. The UE may perform a listen-before-talk (LBT) for one or more of the TTIs in the one or more sets of multiple TTIs, and the UE may transmit, to a base station, an indication of results of the LBT performed for the one or more TTIs. Because the UE may provide the results of the LBT to the base station, the base station may be able to schedule sidelink transmissions from the UE based on the results of the LBT. As such, the UE may experience increased throughput in sidelink communications since the scheduling at the base station may be improved.

Abstract: Methods, systems, and devices for a wireless communication are described. A base station may control multiple parameters for sidelink communication configurations to be used by a user equipment (UE) for sidelink communications. The base station may determine the multiple parameters for sidelink communication configurations and configure multiple UEs for sidelink communication based on the determination. The multiple parameters may include a modulation and coding scheme, a redundancy version, a demodulation reference signal pattern or port, a transmit power control, a sidelink hybrid automatic repeat request (HARQ) indicator, a cast type, a HARQ process number, a receiver UE identifier, or any combination thereof. The indication may be included in downlink control information.

Abstract: Systems and non-transitory computer-readable mediums for scheduling resources for a specific sidelink are described. Some embodiments provide scheduling of resources for a sidelink between a first user equipment (UE) in communication with a base station and a specified second UE in communication with the first UE, such as using downlink control information (DCI) and/or radio resource control (RRC) signaling. The scheduling of sidelink resources may be with respect to a dynamic grant (DG) or a configured grant (CG). Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for sidelink configured grant skipping are described. In some examples, a first user equipment (UE) may receive, from a base station, an indication of periodic data resources for a plurality of sidelink data transmissions and an indication of negative scheduling request resources for the first UE to report a skipped sidelink data transmission associated with the plurality of sidelink data transmissions. In some examples, the first UE may transmit, to a second UE, an indication of the skipped sidelink data transmission and may transmit, to a base station, a negative scheduling request using the negative scheduling request resources, where the negative scheduling request may report the skipped data transmissions associated with the plurality of sidelink data transmissions.

Abstract: Certain aspects of the present disclosure provide techniques for configuring sidelink slots without symbols for automatic gain control. One aspect provides a method for wireless communication by a user equipment, including receiving a first cyclic prefix of a first symbol within a slot at the user equipment. The method further includes configuring a first automatic gain control setting based on a received power in the first cyclic prefix of the first symbol, and receiving a data portion of the first symbol using the first automatic gain control setting.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit semi-persistent scheduling (SPS) messages to a set of user equipments (UEs) using respective resources corresponding to each UE. The base station may receive, from each of a subset of UEs from the set of UEs, a negative acknowledgement (NACK) message associated with the SPS messages. The base station may transmit a group downlink control message including information associated with a downlink resource configuration for retransmission of the respective SPS messages to the subset of UEs. The base station may retransmit SPS messages to each of the subset of UEs using the downlink resource configuration.
