Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a base station, a downlink communication that includes an indication of a sidelink grant associated with the first UE. The first UE may identify, based at least in part on the sidelink grant, one or more sidelink resources in which a second UE is to transmit sidelink control information (SCI) to the first UE. The SCI may include information associated with a sidelink data transmission from the second UE to the first UE. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support cross-slot scheduling of sidelink transmissions in a wireless communication system. A transmitting user equipment (UE) in communication with a receiving UE over a sidelink transmits cross-slot schedule information to the receiving UE at a time prior to a first slot over which a physical sidelink shared channel (PSSCH) transmission is to be transmitted to the receiving UE. The cross-slot schedule information includes information that is sufficient to decode the PSSCH transmission received by the receiving UE at the first slot, without requiring the receiving UE to decode a physical sidelink control channel (PSCCH) transmission including a sidelink control information (SCI) message received during the first slot. In aspects, the PSSCH transmission may be decoded in parallel with the PSCCH transmission received in the first slot.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating an aggregated sidelink resource reservation rule for reserving time-contiguous transmission time intervals. The UE may transmit a sidelink control reservation message based on the aggregated sidelink resource reservation rule. The sidelink control reservation message may indicate a starting transmission time interval for reserving a set of time-contiguous transmission time intervals in a sidelink shared channel. Additionally or alternatively, the sidelink control reservation message may indicate a quantity of the set of time-contiguous transmission time intervals reserved for transmission of a set of aggregated sidelink messages. The UE may transmit the set of aggregated sidelink messages via the set of time-contiguous transmission time intervals of the sidelink shared channel indicated in the sidelink control reservation message.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify a listen-before-talk (LBT) procedure to use for transmitting a downlink signal to a user equipment (UE) on a shared radio frequency spectrum band. The LBT procedure may be a group LBT procedure associated with a first set of contention window durations or an individual listen-before talk procedure associated with a second set of contention window durations. The base station may determine a contention window duration corresponding to the identified LBT procedure, perform the identified LBT procedure using the determined contention window duration, and transmit the downlink signal to the UE based on the performed LBT procedure.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for narrowband communications using frequency hopping in an unlicensed frequency band. In some implementations, a base station (BS) may transmit downlink (DL) data using a sequence of DL hopping frames on a corresponding sequence of unique hopping channels associated with a DL frequency hopping pattern. In some implementations, each user equipment (UE) of one or more UEs may transmit uplink (UL) data using a sequence of UL hopping frames on a corresponding sequence of unique hopping channels associated with a different UL frequency hopping pattern.

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: Wireless communications systems and methods related to channel occupancy management for new radio side-link supporting star topology of user equipment devices are provided. In some aspects, a user equipment (UE) determines a communication resources pool including a channel occupancy ratio (CR) gap of each UE of a plurality of UEs in communication with the first UE, a CR gap of each UE representing a difference between a CR limit of that UE and a CR of that UE, The UE also can communicate, to a second UE of the plurality of UEs, a first CR command configured to allow the second UE to access a first portion of the communication resources pool. In some aspects, an amount of the first portion can be different from an amount of the CR gap of the second UE in the communication resources pool.

In a first aspect, a first UE receives at least one sidelink transmission from a second UE with a sidelink control information (SCI) message that triggers least one IM-based feedback message codebook. The first UE may determine an IM-based feedback message sequence, determine, based on the feedback sequence, a resource for transmission of the IM-based feedback message, wherein a resource index corresponds to the determined feedback message sequence. The first UE may then transmit the IM-based feedback message codebook on the determined resource to the second UE over the sidelink. Other aspects and features are also claimed and described.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support sidelink transmission resource aggregation for in-coverage new radio sidelink (NR SL) operations. In a first aspect, a method of wireless communication includes obtaining a sidelink aggregation factor identifying a number of sidelink resource slots available to a user equipment (UE) to add to each sidelink resource slot allocated in a grant of sidelink channel access from a serving base station. The UE may then receive a sidelink transmission grant identifying at least one granted sidelink resource slot, and determine an aggregated set of sidelink resource slots for each granted sidelink resource slot. The UE may then transmit sidelink communications using the aggregated set of sidelink resource slots for each granted sidelink resource slots used for the sidelink communications. Other aspects and features are also claimed and described.
