Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmission-adjusting wireless node may transmit a first communication via a sidelink channel. The transmission-adjusting wireless node may receive, from a feedback-reporting wireless node, transmission-specific information relating to at least one of a channel quality of the sidelink channel or a power level for the transmission-adjusting wireless node. The transmission-specific information may be based at least in part on the first communication. The transmission-adjusting wireless node may adjust, based at least in part on the transmission-specific information, a transmission property of the transmission-adjusting wireless node to obtain an adjusted transmission property. The transmission-adjusting wireless node may transmit a second communication via the sidelink channel using the adjusted transmission property. Numerous other aspects are provided.

Abstract: Apparatus, methods, and computer-readable media for facilitating beam-based sequence spaces for synchronization signals are disclosed herein. An example method for wireless communication for a first device includes selecting a subset of synchronization signal block (SSB) occasions including SSB occasions within an SSB period, and wherein the subset of SSB occasions is associated with a pairing of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The example method also includes transmitting an SSB using at least one SSB occasion from the subset of SSB occasions. An example method for wireless communication for a user equipment (UE) includes selecting a synchronization signal pairing associated with a pairing of a PSS and a SSS, wherein the synchronization signal pairing maps to a subset of SSB occasions including SSB occasions within an SSB period, and also includes monitoring for an SSB at each SSB occasion from the subset of SSB occasions.

Abstract: Aspects of the disclosure relate to mechanisms for sidelink radio frame timing synchronization in a sidelink network. In some examples, a sidelink device may detect a sidelink synchronization signal (S-SS) transmitted by another sidelink device over a sidelink carrier and determine the sidelink reception timing of the radio frame carrying the S-SS based on the S-SS. The sidelink device may then determine a timing advance value indicative of a propagation delay between the sidelink devices and calculate the sidelink transmission timing of a radio frame within which the sidelink device may transmit information based on the sidelink reception timing and the timing advance value.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first transmitting UE, a first transmission on a first resource, wherein the first transmission includes information associated with reserving a second resource for a second transmission by the first transmitting UE. The UE may transmit, for reception by one or more second transmitting UEs and before an occurrence of the second resource, a message associated with indicating that the second resource is reserved for the second transmission by the first transmitting UE. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, in a first time slot, a set of resources to use for transmission to another UE; evaluate, in a second time slot, whether one or more resources of the set of resources is available; and transmit, based on the one or more resources of the set of resources being available, information to the other UE in a third time slot and using the set of resources, or reselect, based on the one or more resources of the set of resources being unavailable, another resource for transmission of the information to the other UE. Numerous other aspects are provided.

Abstract: A transmitting device may determine a zone identifier (ID) for the transmitting device and transmit a message including the zone ID directly to at least one receiving device. In certain aspects, a relay device may be configured to receive the message comprising a first zone ID for a transmitting device, to determine whether to relay the message based at least on the first zone ID, and if the relay device determines to relay the message, to transmit a relayed message including information reflecting the first zone ID. In certain aspects, a receiving device may be configured to identify a message comprising information indicating a first zone ID for a transmitting device, to determine whether to decode data of the message based at least on the first zone ID for the transmitting device, and to decode or refrain from decoding the data of the message based on the determination.

Abstract: Improvements may be made for an apparatus performing congestion control considering different technologies, types of radio resources, and priorities of different packets. The apparatus may be a UE. The UE determines a channel busy ratio (CBR). The UE determines one or more channel resource utilization limits based on the CBR, where each channel resource utilization limit of the one or more channel resource utilization limits corresponds to a respective packet priority. The one or more channel resource utilization limits are also a function of a CBR limit. The UE controls transmission of a plurality of packets based on the one or more channel resource utilization limits, and each packet of the plurality of packets has a respective packet priority.

Abstract: Certain aspects provide a method for radar detection by an apparatus. The method generally includes transmitting a radar waveform in sets of transmission time intervals (TTIs), using a common set of radar transmission parameters in each set of TTIs, to perform detection of a target object, varying at least one of the common set of radar transmission parameters between sets of TTIs, and identifying interfering signals based on observed changes in monitored parameters of received signals across sets of TTIs due to the varying.

Abstract: Techniques and apparatus for zone-based soft resource partitioning for high reliability high range communications (HRHRC) are described. A first wireless device determines, based at least in part on a location of the first wireless device and a type of traffic associated with the first wireless device, whether to use a first set of resources or a second set of resources for communications between the first wireless device and a second wireless device. The first wireless device communicates with the second wireless device on the first or second sets of resources, in accordance with the determination. The communications involve the type of traffic.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a preferred beamforming direction for communications with each of a plurality of neighbor UEs. The apparatus may transmit a first scheduling request to a second UE from among the plurality of neighbor UEs. In certain aspects, the first scheduling request may include a first transmission schedule for M transmission opportunities (TxOPs). In certain other aspects, the first transmission schedule may indicate a first set of TxOPs of the M TxOPs reserved by the first UE for communication with the second UE. The apparatus may receive a first scheduling response from the second UE, the first scheduling response indicating whether the second UE accepts or rejects the first scheduling request.
