Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE via a sidelink sub-channel of a licensed carrier, an indication of multiple data channels of an unlicensed carrier to be used to attempt one or more sidelink communications between the first UE and the second UE. The UE may attempt the one or more sidelink communications between the first UE and the second UE using the multiple data channels. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device (base station or UE) may receive an indication of a listen before talk (LBT) gap for sharing a channel occupancy time (COT), the COT being acquired by another wireless device (base station or UE), and detect whether a slot within the COT is occupied by the other wireless device, the slot occurring prior to the LBT gap. The wireless device may also, responsive to detecting that the slot is occupied by the other wireless device, preform an LBT procedure during the LBT gap, and, responsive to a successful LBT procedure, transmit a signal to the other wireless device within the COT.

Abstract: Wireless communications systems and methods are provided for validating a physical uplink shared channel (PUSCH) occasion defined for 2-step random access channel (RACH) in case of collisions. For example, the user equipment (UE) may determine whether a collision occurs between the PUSCH occasion for the 2-step RACH and any RACH occasion assigned for either 2-step RACH or 4-step RACH after receiving the RACH configuration or updates from the network. The UE may then exclude the PUSCH occasion from the resource pool for 2-step RACH when a collision occurs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may attempt to receive one or more random access channel (RACH) messages from one or more user equipment (UEs); and transmit, based at least in part on the determination of a completion of processing of any received RACH messages of the one or more RACH messages, an early termination message to a UE to terminate a random access response window. In some aspects, a UE may transmit another RACH message as a response to receiving the early termination message. Numerous other aspects are provided.

Abstract: Some aspects described herein relate to receiving a configuration defining resources for transmitting a first message in a two-step random access procedure, wherein the first message includes a random access preamble and a payload, generating a beacon signal for transmitting as the first message, where the beacon signal includes one or more parameters to facilitate discovery by other UEs for pairing in sidelink communications, and transmitting, based on the configuration, the beacon signal as the first message over the resources.

Abstract: Certain aspects of the present disclosure provide techniques for reuse one channel access for new radio communications in unlicensed spectrum. A method that may be performed by a first base station (BS) includes occupying a bandwidth, based on a category 4 (CAT4) listen before talk (LBT) procedure on the bandwidth, wherein the CAT4 LBT procedure is based on a first contention window (CW); arranging a category 2 (CAT2) LBT occasion for the bandwidth during a channel occupancy time (COT) for the bandwidth; and receiving an indication that at least a second BS has occupied the bandwidth during the CAT2 LBT occasion.

Abstract: Certain aspects of the present disclosure provide techniques for new radio (NR) communications in narrowband regions of unlicensed spectrum. A method that may be performed by a user equipment (UE) includes determining, using an energy detector (ED), that received energy in a first bandwidth (BW) is lower than a threshold; and transmitting, in response to determining that received energy in the first BW is lower than the threshold, a first uplink (UL) transmission to a base station (BS) in a second BW smaller than the first BW and contained within the first BW.

Abstract: Techniques for spectrum sharing among operators are provided. A base station (BS) licensed to a first operator monitors, while operating on a first carrier frequency assigned to the first operator, a reservation period on a second carrier frequency assigned to a second operator that shares spectrum with the first operator. The BS determines, based on the monitoring, availability of the second carrier frequency for use by the BS during at least one subsequent data period. The BS determines whether to attempt to reserve access on the second carrier frequency for use during the at least one subsequent data period based on the determined availability.
