Abstract: This disclosure provides systems, methods, and devices for wireless communication that support mechanisms for sidelink beamforming alignment over a set of resources based on a deterministic sequence in a wireless communication system. In aspects, an sidelink initiator user equipment (UE) may initiate a beamforming alignment procedure with a responder UE over a the sidelink. The initiator UE may define a set of subchannels specified by a deterministic sequence. The set of subchannels may be subchannels over which the initiator UE may perform reception beam sweeping. The deterministic sequence may be anchored to a direct frame number (DFN) of the sidelink frame without initial sensing, and may be determined via a sequence index, as a function of sidelink UE identification ID(s), or a combination thereof. In this manner, the number of bits for indicating the deterministic sequence to the responder UE may be reasonable, manageable, and/or moderate.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support a super slot configuration for new radio (NR) sidelink over millimeter wave (mmW) operating frequencies. In a first aspect, a method of wireless communication by a user equipment (UE) includes obtaining a sidelink resource pool configuration including configuration of one or more super slots, wherein each super slot includes a plurality of slots contiguous in a time domain The UE may select one or more sidelink resource slots for sidelink transmissions in a sidelink resource pool and transmit an enhanced sidelink control information (eSCI) message in a first slot of a first super slot, wherein the eSCI message indicates a reservation of slots corresponding to the one or more sidelink resource slots. The UE may then send the sidelink transmissions on at least one slot of the reserved slots. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive sidelink control information from a second wireless device. The sidelink control information may include an allocation of a first set of resources for a sidelink transmission from the second wireless device to the first wireless device, along with an indication that schedules a second set of resources for additional sidelink transmissions between the first wireless device and the second wireless device that are scheduled to occur after the sidelink transmission from the second wireless device to the first wireless device. Based on the received indication, the first wireless device may communicate with the second wireless device via a sidelink shared channel using the first set of resources and the second set of resources.

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: 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.
