Abstract: Systems and methods implementing receiver assisted channel access procedures configured to enable access for a potential transmitter while avoiding introducing unacceptable interference with respect to ongoing communications in a shared channel are described. In examples, a receiver assisted channel access procedure implements a LBT enhanced CCA (eCCA) technique in which receiver assisted transmitter sensing is utilized. A receiver assisted channel access procedure may implement monitoring of a shared channel during a contiguous contention period for one or more instances of a periodic session protection signal.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may obtain a channel occupancy time (COT) in an unlicensed frequency spectrum band. The COT may include an initial time interval for an initial transmission and a subsequent time interval for a subsequent transmission. In the initial time interval, the UE may transmit control information and data to another UE, where the control information indicates the subsequent time interval. The other UE may selectively perform communications during the subsequent time interval. The UE may perform the subsequent transmission during the subsequent time interval.

Abstract: Wireless communications systems and methods related to sidelink communications in an unlicensed frequency band are provided. A user equipment (UE) receives, from a base station (BS), a first downlink control information (DCI) associated with a first listen-before-talk (LBT) time. The UE determines a first sidelink transmission opportunity for communicating in an unlicensed frequency band at the first LBT time based on the first DCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a resource grant for at least one sidelink channel, wherein the resource grant indicates a first uplink resource for transmitting sidelink transmission acknowledgement messages and a second uplink resource for transmitting listen-before-talk statuses. The UE may transmit, to the base station and on the second uplink resource, an indication of at least one status associated with a listen-before-talk procedure used on the at least one sidelink channel. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may identify an energy per resource element (EPRE) ratio between a synchronization signal block (SSB) symbol containing a primary synchronization signal (PSS) and an SSB symbol containing a secondary synchronization signal (SSS), a physical broadcast channel (PBCH), or both, based on an operating band for the UE, a bandwidth of the SSB symbol containing the PSS and the SSB symbol containing the SSB, the PBCH, or both. The EPRE ratio may be based on maximum regulatory equivalent isotropically radiated power (EIRP) limits, maximum regulatory power spectral density (PSD) limits for the band, or both. The EPRE ratios may be different for different SSB symbols, when different SSB symbols have different bandwidths. A base station may configure and transmit, and a UE may receive, the SSB according to the identified EPRE ratio.

Abstract: Methods, systems, and devices for wireless communications are described. In a first case, a first user equipment (UE) may transmit to a second UE a sidelink discovery message preamble corresponding to a sidelink discovery message. The first UE may identify resources for transmission of the sidelink discovery messages based on the sidelink discovery message preamble. The first UE may either transmit the sidelink discovery message to the second UE or may receive the sidelink discovery message from the second UE using the identified resources for the transmission of the sidelink discovery message. In some cases, the second UE may transmit sidelink control information (SCI) to the first UE, and may transmit a sidelink discovery message to the first UE based on resources identified in the SCI. In some cases, the first UE may transmit the sidelink discovery message without transmission of a preamble or a SCI.

Abstract: Methods, systems, and devices for wireless communications are described. A hub user equipment (UE) in a star topology may broadcast to a set of peripheral UEs indicating slots when the hub UE will not be in a transmission mode. The hub UE may broadcast a slot format indication to the peripheral UEs to indicate operating modes in a set of slots. In a first group of slots, the hub UE may operate in a forward mode, transmitting sidelink communications to the peripheral UEs. In a second group of slots, the hub UE may operate in a reverse mode, receiving sidelink communications from the peripheral UEs. In slots when the hub UE operates in the reverse mode, if a peripheral UE does not have data or control information, the peripheral UE may enter a sleep mode in one or more slots of the second group to save power.

Abstract: Systems, methods, and devices for wireless communication that support mechanisms for non-coherent, sequence-based downlink control signaling in a wireless communication system. In aspects, the mechanisms for non-coherent, sequence-based downlink control signaling may include a new non-coherent, sequence-based downlink control channel or signal transmitted from a base station to a user equipment (UE) and configured to convey information bits (e.g., control information bits) to the UE. The UE may receive a signal transmitted over the new non-coherent, sequence-based downlink control channel and may decode the signal to extract the control information. The UE may then apply a control based on the control information received from the base station in the signal over the non-coherent, sequence-based downlink control channel.
