Abstract: Methods, systems, and devices for wireless communications are described. A first device node, such as an end station or a user equipment (UE) associated with the end station, may receive, from a controller node of a time-sensitive network (TSN), a configuration for communicating over the TSN. The TSN may include a plurality of nodes that are synchronized according to a common synchronization configuration and that are configured for transmitting messages between the controller node and the first device node within a latency threshold condition configured for the TSN. The first device node may identifying data to transmit to a second device node of the plurality of nodes and may communicating with the second device node via a sidelink connection associated with the wireless radio access network.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support configured reception with sidelink control information (SCI) repetition over a sidelink. In aspects, a receiving user equipment (UE) may be configured to conduct combined reception/decoding of SCI repetitions (received from a transmitting UE over a sidelink) over multiple time-frequency slots at pre-defined occasions (e.g., occasions configured by a base station) to decode a sidelink transmission. In aspects, a receiving UE may receive from a transmitting UE over a sidelink, a sidelink transmission during a reception occasion that includes a plurality of reception opportunities for the receiving UE. Each reception opportunity of the plurality of reception opportunities includes a repetition of an SCI. The receiving UE decodes the SCI by combining the repetitions of the SCI received in one or more reception opportunities, and decodes a data transmission (e.g., a physical sidelink shared channel (PSSCH) transmission) using the decoded SCI.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may be configured to receive, from a second wireless device via a sidelink communication link, a sidelink control information (SCI) scheduling an uplink transmission from the first wireless device to the second wireless device. The first wireless device may then generate the uplink transmission based on the SCI. The first wireless device may then transit the uplink transmission to the second wireless device via the sidelink communication link in accordance with the SCI.

Abstract: Methods, systems, and devices for wireless communications at a device are described. The device may receive an indication of a configuration that schedules semi-persistently scheduled resources for transmissions from the first device. The device may also receive an indication of a set of resources available to the first device for requesting a set of the semi-persistently scheduled resources configured for the first device. The device may transmit a message over the set of resources to request the set of semi-persistently scheduled resources.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be configured to transmit a first sidelink control information (SCI) message associated with a first sidelink transmission from the first UE, the first SCI including a first indication of a first set of resources reserved for retransmissions of the first sidelink transmission at one or more retransmission occasions. The UE may identify a second SCI message associated with the first SCI message, the second SCI message including frequency domain resource allocation (FDRA) field values indicative of a second set of resources reserved for retransmissions of a second sidelink transmission, where the second SCI provides a release of at least some of the reserved resources. Additional aspects of signaling one or more configurations via resource indication fields are described.

Abstract: A device may use sidelink request and sidelink response (e.g., DSS/STS and DRS) resources (in a sub-band) of different sizes depending on whether the sub-band is a primary sub-band or secondary sub-band. The device may transmit more information in the request/response resources of a primary sub-band than in the request/response resources of a secondary sub-band. The device may transmit small amounts of information in its request/response resources in secondary sub-bands. The resources in the secondary sub-bands may include, for example, reference signals, and signals indicating occupation of the sub-band. The device may utilize tone signaling for request/response signaling in the secondary sub-bands (at least because the amount of information being conveyed in the secondary sub-bands is small) and digital signaling in the primary sub-band (at least because the amount of information being conveyed in the primary sub-band is large in comparison to that being conveyed in the secondary sub-bands).

Abstract: Methods, systems, and devices for wireless communications are described. For example, a method for wireless communications at a transmitting user equipment (UE) may include receiving, from a base station, a resource configuration of sidelink communications. The transmitting UE may transmit, to a receiving UE, sidelink control information (SCI) via one or more SCI messages, the SCI comprising one or more semi-persistent scheduling indications pertaining to a semi-persistent scheduling configuration for communications from the transmitting UE to the receiving UE. The transmitting UE may monitor for feedback information pertaining to the SCI prior to proceeding with semi-persistent scheduled sidelink transmissions in accordance with the one or more semi-persistent scheduling indications.

Abstract: Methods, systems, and devices for wireless communications are described. A first device, which may be a user equipment (UE), may transmit a sidelink control information SCI) message (e.g., an SCI-1 message) on a physical sidelink control channel (PSCCH) to a group of devices. The SCI may message may reserve a set of sidelink resources for a sidelink communication between the first device and a second device of the group of devices. The first device may receive an acknowledgment (ACK) message on a physical sidelink feedback channel (PSFCH) from the second device. Based on receiving the ACK message, the first device may release the set of sidelink resources and may transmit a release message (e.g., a physical sidelink release channel (PSRCH) message) on a PSRCH that includes an indication of the released set of sidelink resources.
