Abstract: A method or apparatus for wireless communication at a wireless device. The wireless device transmits sidelink control information (SCI) indicating an aperiodic resource reservation and indicating a time gap between aperiodic resource reservations based at least in part on supplemental bits. The apparatus transmits a sidelink message based on the aperiodic resource reservation on a resource pool that supports periodic resource reservation

Abstract: Aspects relate to time-interleaving of code block groups (CBGs) of a transport block. Some deployments can include configuring a downlink transmission to a scheduled entity that overlaps in time with an uplink transmission from the scheduled entity when the scheduled entity is operating in a full-duplex mode. CBGs may be time-interleaved to accommodate and/or mitigate interference between downlink and uplink transmissions. The modulation and coding scheme (MCS) of the transport block can further be adjusted to accommodate and/or mitigate interference between the downlink and uplink transmissions. Techniques discussed herein can be used at various nodes, components, and/or devices in a wireless network (e.g., UEs, BSs, CUs, RUs, DUs, etc.). Other aspects, features, and embodiments are also claimed and described.

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: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for segmenting uplink control information prior for encoding using a polar code prior to transmission. An exemplary method that may be performed by a wireless device generally includes iteratively segmenting a group of K information bits into a plurality of segments, encoding the information bits of each of the plurality of segments using a polar code to generate a plurality of encoded segments, and transmitting the plurality of encoded segments.

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: 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.
