Abstract: This disclosure provides systems, methods, and apparatuses for supporting network transmissions using unicast sidelink communications. A base station (BS) may transmit a set of encoded packets to a number of user equipment (UEs) and receive feedback messages from the UEs that indicate sets of decoded packets. Based on the feedback messages, the BS may transmit an updated set of encoded packets based on a difference between the set of encoded packets and the union of decoded packets. The BS may transmit an instruction to a first UE to transmit a unicast sidelink communication to a second UE that includes a set of missed packets that includes one or more decoded packets that were decoded by the first UE but were not decoded by the second UE. The first UE may transmit the unicast sidelink communication to the second UE.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a first communication node (e.g., UE, BS, etc.) obtains one or more measurements associated with one or more PRSs (e.g., uplink PRS(s), downlink PRS(s), etc.) The first communication node transmits, to a second communication node (e.g., UE, BS, etc.) via L1 or L2 signaling, a report based on the one or more measurements. The second communication node receives the report and performs a position computing function based on the report.

Abstract: Aspects presented herein may enhance the configuration of the scheduling offset for communication devices within a channelized frequency band. In one aspect, a UE receives a PDCCH including a scheduling offset parameter. The PDCCH schedules one of a PDSCH for reception in a first sub-band within a BWP or provides an uplink scheduling grant of a PUSCH for transmission in a second sub-band within the BWP. The UE communicates with a base station based on one of a slot for receiving the PDSCH based on the first sub-band within the BWP and the scheduling offset parameter when the PDCCH schedules the PDSCH, or a slot for transmitting the PUSCH based on the second sub-band within the BWP and the scheduling offset parameter when a PUCCH is used to schedule the PUSCH.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support configured reception with sidelink control information (SCI) repetition over a sidelink. In aspects, a receiving user equipment (UE) may be configured to conduct combined reception/decoding of SCI repetitions (received from a transmitting UE over a sidelink) over multiple time-frequency slots at pre-defined occasions (e.g., occasions configured by a base station) to decode a sidelink transmission. In aspects, a receiving UE may receive from a transmitting UE over a sidelink, a sidelink transmission during a reception occasion that includes a plurality of reception opportunities for the receiving UE. Each reception opportunity of the plurality of reception opportunities includes a repetition of an SCI. The receiving UE decodes the SCI by combining the repetitions of the SCI received in one or more reception opportunities, and decodes a data transmission (e.g., a physical sidelink shared channel (PSSCH) transmission) using the decoded SCI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first sensing signal of a radio frequency (RF) sensing procedure at a first transmit power. The UE may receive, from a base station at least in part in response to the first sensing signal, a power control message for sensing signals of the RF sensing procedure. The power control message may indicate a power control strategy for transmitting sensing signals of the RF sensing procedure. The UE may then transmit, at a second transmit power based on the received power control message, a second sensing signal of the RF sensing procedure.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may transmit sets of network coding encoded packets user equipments (UEs), and each set of network coding encoded packets may be associated with a redundancy overhead. The base station may dynamically identify the redundancy overhead for transmitting sets of network coding encoded packets to each UE based on a failure rate associated with a previous transmission of network coding encoded packets to that UE. For example, the base station may determine a failure rate associated with a transmission of a first set of network coding encoded packets and may identify a redundancy overhead associated with one or more second sets of network coding encoded packets based on the determined failure rate. In some cases, the base station may identify different redundancy overheads for transmissions of network coding encoded packets to different UEs.

Abstract: Systems, methods, and devices for wireless communication that support mechanisms for determining a joint priority of sidelink and access link (Uu) positioning reference signal (PRS) transmissions in a wireless communication system. A joint priority of a PRS transmission may refer to a priority of the PRS transmission over the entire set of PRS transmissions including sidelink PRS transmissions and Uu PRS transmissions transmitted to a target UE in a sidelink positioning session. In aspects, a joint priority of a sidelink PRS transmission from an anchor UE may be determined with respect to not only other sidelink transmissions, but also with respect to other Uu PRS transmissions from other anchor base stations. Similarly, a joint priority of a Uu PRS transmission from an anchor base station may be determined with respect to not only other Uu transmissions, but also with respect to other sidelink PRS transmissions from other anchor UEs.

Abstract: Aspects of the present disclosure provide techniques for sub-band conversion or cancellation for dynamic scheduling of sub-band full duplex (SBFD) operations between the base station and UEs. The capability to communicate via simultaneous UL and DL transmissions through dynamic scheduling allows for increased uplink duty cycle leading to latency reduction (e.g., it is possible to receive DL signal in an UL only slots, which can enable latency savings) and improved uplink coverage. Additionally enabling flexible and dynamic UL and DL resource adaptation in accordance with techniques of the present disclosure also provide enhanced system capacity, resource utilization, and spectrum efficiency.

Abstract: Certain aspects of the present disclosure provide techniques for channel access in an unlicensed spectrum. An example method of wireless communication by a user equipment includes receiving a resource grant indicating a plurality of resource candidates for an uplink signal. The method also includes sensing for energy, in response to the resource grant, over one or more of the resource candidates in a first sensing occasion before a transmission occasion of the uplink signal. The method further includes transmitting, during the transmission occasion, the uplink signal using a subset of the resource candidates selected based at least in part on energy sensed in the first sensing occasion.
