Abstract: Certain aspects of the present disclosure provide techniques for bit interleaving for sidelink communication with interlaced waveform. A method that may be performed by a user equipment (UE) includes mapping first bits and second bits to resource blocks (RBs) such that the first bits are mapped to first subcarriers of the RBs, a first subset of the second bits are mapped to the first subcarriers, and a second subset of the second bits are mapped to second subcarriers of the REs; and transmitting the first bits and the second bits via the RBs according to the mapping.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, at a second protocol layer of the UE and from a first protocol layer of the UE, the second protocol layer being lower than the first protocol layer, an indication of one or more quality of service parameters associated with a data packet to be transmitted by the UE. The UE may identify, from the one or more quality of service parameters, directional coverage information associated with the data packet, the directional coverage information indicative of one or more transmission directions in which the data packet is to be transmitted. The UE may transmit the data packet in accordance with at least the directional coverage information of the one or more quality of service parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a second UE, a first sidelink synchronization signal (SLSS) at a first transmission-reception point (TRP) and a second TRP different from the first TRP. The first UE may perform a first set of measurements on the first SLSS received at the first TRP and a second set of measurements on the first SLSS received at the second TRP. The first UE may then transmit, to a third UE, a second SLSS based at least in part on the first set of measurements, the second set of measurements, or both, satisfying one or more measurement thresholds.

Abstract: In various embodiments supporting directional security, a user equipment (UE) may receive from a network device a noise resource allocation including an indication of a noise direction and a noise parameter, generate a noise signal based at least in part on the noise parameter, and transmit the noise signal in the noise direction while transmitting a communication transmission signal in a different direction from the noise direction. In various embodiments, a network device may determine a geographic zone of interest, select one or more reconfigurable intelligent surfaces (RISs) associated with the geographic zone of interest, selecting one or more noise transmitting UEs, control the one or more noise transmitting UEs to transmit at least one noise signal, and control the one or more RISs to steer the at least one noise signal into the geographic zone of interest.

Abstract: Certain aspects of the present disclosure provide techniques for sidelink communications in an unlicensed spectrum. A method that may be performed by a first user equipment (UE) of a plurality of UEs includes sensing a frequency band to determine whether the frequency band is idle, the sensing occurring prior to a first time period. In some examples, the method may include transmitting, by the first UE, one or more signals over the frequency band during the first time period based on determining that the frequency band is idle, the one or more signals indicating that the frequency band is reserved for wireless communication between the plurality of UEs during the first time period.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may reserve one or more time frequency resources in an unlicensed frequency spectrum band for one or more sidelink transmissions. The UE may reserve the time frequency resources through a sidelink message transmitted in a first slot of a shared channel occupancy (CO). The UE may monitor a subset of slots before the reserved time frequency resources for sidelink transmissions from other UEs sharing the CO. The monitoring of the subset of slots may include decoding control messages or control information in each of the subset of slots, a reference signal received power (RSRP) measurement of sidelink transmissions in the subset of slots, channel sensing with energy detection in a sensing window, or a combination thereof. The UE may communicate in the reserved slot based on the monitoring.

Abstract: Certain aspects of the present disclosure provide techniques for slot format for sidelink communication. A method that may be performed by a user equipment (UE) includes refraining from transmitting during a gap portion of a first symbol in time of a sidelink transmission, wherein the first symbol comprises the gap portion and a signal portion; transmitting a signal during the signal portion of the first symbol; and transmitting a data signal of the sidelink transmission in at least one second symbol subsequent in time to the first symbol in the sidelink transmission.
