Abstract: Certain aspects of the present disclosure provide a method performed by a first apparatus including a radar device. The first apparatus transmits first operating information associated with the first apparatus indicating a geographical location and a direction of the first apparatus to a second apparatus in an environment. The first apparatus receives second operating information from the second apparatus indicating a geographical location and a direction of the second apparatus. The first apparatus identifies a group of interfering apparatuses, including the first apparatus and the second apparatus, based on the first and second operating information. The group of interfering apparatuses is associated with a same time synchronization source. The first apparatus transmits a first plurality of signals via the radar device based on a common radar transmission configuration for the group of interfering apparatuses.

Abstract: In an aspect, the present disclosure includes a method and apparatus for sidelink communications for identifying a number of non-sidelink occupied resources in a measurement window having a total number of resources in an unlicensed spectrum, wherein the total number of resources can be used by sidelink transmissions and non-sidelink transmissions, determining a channel occupancy ratio (CR) limit for a sidelink transmission based on at least a channel busy ratio (CBR) determined accounting for at least the number of non-sidelink occupied resources in the measurement window, calculating a CR for a sidelink transmission, and transmitting, or refraining from transmitting, the sidelink transmission respectively based on whether the CR does not or does exceed the CR limit.

Abstract: A first UE may configure, during a COT, an initial transmission and one or more subsequent transmissions that follow the initial transmission. The one or more subsequent transmissions are configured to prevent a release of the COT. Based on the configuration, the first UE may transmit the initial transmission including an indication of the COT and a time period for transmitting the one or more subsequent transmissions. The first UE may subsequently transmit the one or more subsequent transmissions during the indicated time period. A second UE may receive the indication of the COT and the time period where the release of the COT is prevented. The second UE may prepare a packet for transmission during the time period where the release of the COT is prevented and transmit the packet during the COT following the time period where the release of the COT is prevented.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, from an available resource pool, one or more resources for transmitting a packet on a channel. The UE may determine that a new shared channel occupancy time (COT) has been initiated on the channel. The UE may adapt at least one resource of the one or more resources for transmitting the packet based at least in part on determining that the new shared COT has been initiated. Numerous other aspects are provided.

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: 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.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a transmitter user equipment (UE) determines a first demodulation reference signal (DMRS) pattern for a first slot allocated for transmission over a sidelink between the transmitter UE and a receiver UE, wherein the first DMRS pattern is determined based at least on the first slot having a first slot format of two or more slot formats, and transmits, to the receiver UE, DMRS in the first slot according to the first DMRS pattern. In an aspect, the receiver UE determines the first DMRS pattern for the first slot based at least on the first slot having the first slot format, and receives, from the transmitter UE, DMRS in the first slot according to the first DMRS pattern.
