Abstract: Certain aspects of the present disclosure provide techniques for using physical resource blocks (PRBs) of a sidelink resource pool that, in some cases, might not belong to a sub-channel in sidelink or are assigned to a special sub-channel. When a user equipment (UE) is transmitting a sidelink communication, the sidelink communication often takes place in resource pools that include sub-channels in frequency domain and slots in a time domain. A first subset of PRBs of the resource pool may be assigned to one or more sub-channels in the frequency domain. The disclosed methods, devices, and systems provide for identifying PRBs not assigned to the first subset (e.g., remaining or unused PRBs or PRBs assigned to a special sub-channel). In some aspects of the present disclosure, the UE may use these PRBs for various purposes.

Abstract: Certain aspects of the present disclosure provide techniques for indication of resource collisions in sidelink. A method that may be performed by a user equipment (UE) includes generating information including one or more resource collisions between sidelink devices. The method generally includes transmitting the information to at least one of the sidelink devices.

Abstract: Certain aspects of the present disclosure provide techniques for recovering a sidelink communication. A wireless node may receive a plurality of sidelink communications, each sidelink communication between two user equipments (UEs); and transmit recovery information in a recovery slot, wherein the recovery information is for recovery of at least one of the sidelink communications by the two UEs or other UEs that transmitted when at least one of the sidelink communications occurred and wherein the recovery slot is for transmission of the recovery information.

Abstract: Aspects described herein relate to preempting or cancelling sidelink or uplink resources of one or more devices to allow sidelink or uplink transmissions of one or more other devices, and/or determining subsequent resources for transmitting communications based on the preempted or cancelled sidelink or uplink resources. In an aspect, an indication to preempt receiving communications or cancel transmitting communications over scheduled resources can be received, and based at least in part on the indication, subsequent resources over which to receive or transmit the communications can be determined. The communications can be received or transmitted in the subsequent resources.

Abstract: Aspects relate to obtaining, at a first scheduled entity, a first priority ranking of first uplink (UL) data scheduled for transmission to a scheduling entity and a first data scheduled for transmission to a second scheduled data, as well as a second priority ranking of second data scheduled for transmission to a third and fourth scheduled entity, respectively. The scheduling uses at least a portion of a sidelink resource reserved for sidelink communication for the transmissions. The scheduling of the transmissions using at least the portion of the sidelink resource are based on the first priority ranking and the second priority ranking. Various transmission cancellation and reception preemptions are transmitted from transmitting scheduled entities to other transmitting or receiving scheduled entities, respectively. Such cancellations and preemptions are based on the priority rankings, prediction of data transmission collisions and prediction of interference at receiving entities.

Abstract: Aspects relate to a demodulation reference signal (DMRS) in a sidelink wireless communication network. In some examples, a sidelink device generates a DMRS based on first and second identifiers of the sidelink device. In some examples, a sidelink device generates a DMRS based on an initialization parameter and/or at least one scaling parameter. In some examples, the initialization parameter may be based on a first identifier of a sidelink device. In some examples, the at least one scaling parameter may be based on a second identifier of a sidelink device. In some examples, a first sidelink device synchronizes with a second sidelink device based on broadcast channel information that is obtained by using DMRS information to decode a received broadcast signal. In some examples, the DMRS information may be based on first and second identifiers of the first sidelink device.

Abstract: A method of wireless communication performed by a first user equipment (UE) includes measuring first sensing information and receiving second sensing information from a second UE. The method also includes combining the second sensing information with the first sensing information based on determining a combining condition is satisfied. The method further includes identifying transmission resources from the combined sensing information. The method still further includes transmitting data via the identified transmission resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain one or more measurements associated with a sidelink resource pool that includes one or more time and frequency resources allocated to sidelink transmissions to or from the UE. The UE may transmit, to an assisted UE, sidelink signaling that includes signaling to wake up the assisted UE and resource assistance information indicating the one or more measurements associated with the sidelink resource pool. Numerous other aspects are provided.

Abstract: Aspects directed towards initializing sequence generators to facilitate sidelink communications are disclosed. In one example, a type associated with a sidelink communication is determined. A sequence generator is then initialized with a seed in which the seed is based on the type associated with the sidelink communication. The sequence generator is then utilized to facilitate transmitting at least a portion of the sidelink communication.
