Abstract: A method and apparatus for prioritization of sidelink and uplink. The apparatus compares priorities of a first group of transmission signals to determine a first signal from the first group of transmission signals having a highest priority. The first group of transmission signals comprise at least one uplink signal and at least one sidelink transmission signal. The apparatus compares a priority of the first signal from the first group of transmission signals against a reception signal having a highest priority of a second group of reception signals to determine to transmit at least the first signal from the first group of transmission signals or to receive at least one reception signal from the second group of reception signals. The second group of reception signals comprises at least one sidelink reception signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from one or more additional UEs, one or more indicators corresponding to one or more resource reservations. Accordingly, the UE may transmit data, to a second UE, on a sidelink channel, with at least one resource reservation, of the one or more resource reservations, indicated within a control element transmitted with the data. For example, the control element may include a list or a bitmap indicating the at least one resource reservation. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration. The configuration may indicate component carriers for sidelink carrier aggregation and parameters associated with cross-carrier feedback. The UE may receive a first transmission block on a first component carrier and a second transmission block on a second component carrier. The UE may transmit a physical sidelink feedback channel (PSFCH) on a third component carrier with the cross-carrier feedback. The cross-carrier feedback may include a set of acknowledgement/negative acknowledgement (ACK/NACK) bits and an indication of an association between each ACK/NACK bit and a corresponding one of the first component carrier, the second component carrier, the first transmission block, or the second transmission block. Numerous other aspects are described.

Abstract: A wireless device can use a channel occupancy time (COT) to reserve a spectrum for sidelink positioning operations in a certain time interval. In some examples, multiple wireless devices can share the same COT for performing sidelink positioning and/or ranging operations using unlicensed or shared spectrum. Some aspects of the disclosure provide various processes for handling scenarios when channel access of the unlicensed spectrum is unsuccessful.

Abstract: Aspects relate to techniques for facilitating sidelink cancellation. A network entity, such as a base station, may schedule a sidelink transmission between a transmitting wireless communication device and a receiving wireless communication device and transmit scheduling information for the sidelink transmission to at least the transmitting wireless communication device. The network entity may further transmit control information including a cancellation indication to at least the transmitting UE. The cancellation indication may indicate at least an overlap between a portion of the resources allocated to the sidelink transmission and an additional transmission. Based on the cancellation indication, the transmitting wireless communication device may modify the sidelink transmission.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may select, from stored configuration information or a received indication, an inter-UE coordination scheme that is configured for a resource pool associated with the first UE. The UE may transmit, to a second UE, an indication of one or more of preferred sidelink resources or non-preferred sidelink resources for transmission from the second UE to the first UE, based at least in part on the inter-UE coordination scheme. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE via a sidelink interface between the first UE and the second UE, an indication of a device discovery model associated with the second UE, wherein the device discovery model associated with the second UE is different than a device discovery model associated with the first UE. The UE may perform a device discovery with the second UE based at least in part on the device discovery model associated with the second UE. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure to techniques for sidelink discovery in millimeter wave (e.g., Frequency Range 2 (FR2), or 24.25 GHz to 52.6 GHz) bands. For example, the disclosed techniques provides generating a sidelink discovery message including device information of the UE and non-device information. The sidelink discovery message is outputted for transmission. A sidelink connection with a receiver (Rx) UE can then be established after the output of the sidelink discovery message. Very often, beam training is required for FR2 communications. After beam sweep, the transmitter (Tx) UE and the Rx UE become aware of the primary beam directions and need to discover each other on a device level, by associating a beam pair link to a peer UE. As FR2 link often have high overhead to establish and maintain, the disclosed techniques enables device level and service level discovery using the discover message.
