Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first indication of a default overlap resolution process for application by the UE on a plurality of overlapping transmissions. The plurality of overlapping transmissions may be collectively scheduled by one or more first downlink control information (DCI) messages received by the UE prior to a processing deadline for multiplexing the plurality of overlapping transmissions. The UE may determine, based on the processing deadline having passed, whether any one of the one or more first downlink control information messages includes a second indication of a transmission-specific overlap resolution process for application by the UE on a first two or more overlapping transmissions of the plurality of overlapping transmissions. The UE may perform a determined overlap resolution process including either the transmission-specific overlap resolution process or the default overlap resolution process.

Abstract: This disclosure describes methods, devices, and systems for techniques related to wireless communications, and more particularly uplink transmissions on one or more of a physical uplink shared channel (PUSCH) and a physical uplink control channel (PUCCH). Generally, the described techniques support handling collisions between PUSCH repetitions and a PUCCH transmission. A user equipment (UE) may identify that uplink control information (UCI) is scheduled for transmission via an uplink control transmission that overlaps with multiple repetitions of an uplink data transmission. The UE may determine, for each of the multiple repetitions, a quantity of resources available for carrying multiplexed uplink control information, generate encoded UCI by encoding the UCI based on the quantity of resources available in each of the multiple repetitions, and multiplex the encoded UCI on at least a portion of the multiple repetitions based on the quantity of resources available in each of the multiple repetitions.

Abstract: Aspects are provided for HARQ feedback and retransmission procedures for cooperative relaying in sidelink networks. A relay attempts to decode sidelink data received from a source for relay to a destination. The relay may combine LLRs for the sidelink data and for a retransmission of the sidelink data. The relay determines a resource of a wireless channel for transmitting feedback to the source in response to the decoding attempt. If decoding is successful, the relay transmits the data to the destination. The destination then attempts to decode the data received from the relay. The destination may combine LLRs for the data and for a retransmission of the data. The destination determines a resource of a wireless channel for transmitting feedback to the relay in response to the decoding attempt. The resources are based on a relay identifier associated with the relay.

Abstract: Certain aspects of the present disclosure provide techniques for enhancing sidelink resource utilization for a user equipment (UE) that supports full duplex (FD) communications. For example, an FD UE may receive incoming sidelink communication over a first set of resources and, in FD mode, simultaneously transmit another sidelink communication over the same first set of resources. According to aspects of the present disclosure, the potential interference between the two sidelink communications will be mitigated or reduced, such as by having the FD UE negotiate with other sidelink UEs over transmission power levels and related aspects, such as beam coordination and/or resource subset designation, or the like.

Abstract: Apparatus, methods, and computer-readable media for facilitating a resource reservation indication for mode 2 resource allocation with power saving are disclosed herein. An example method for wireless communication at a wireless device includes mapping one or more slots of a sidelink resource reservation to physical slots based on periodic on-durations of a power saving mode for sidelink communication. The example method also includes transmitting SCI indicating the sidelink resource reservation that indicates the one or more slots. Another example method for wireless communication at a first wireless device includes receiving SCI indicating a sidelink resource reservation for a second wireless device, the SCI indicating one or more slots of the sidelink resource reservation. The example method also includes mapping the one or more slots to physical slots based on periodic on-durations of a power saving mode for sidelink communication.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for DCI content and modified/enhanced codebook Type 3 HARQ PUCCH content for deferred SPS PUCCH ACK/NACK. In aspects, a UE may receive, from a base station, DCI including a request for HARQ-ACK feedback associated with at least one resource that is unavailable. The HARQ-ACK feedback may be based on one or more one-shot HARQ-ACK codebooks including one or more bits. The UE may transmit, to the base station, the HARQ-ACK feedback associated with the at least one resource that is unavailable, where the HARQ-ACK feedback includes the one or more one-shot HARQ-ACK codebooks including the one or more bits.

Abstract: Wireless communications systems and methods related to transmitting sidelink channel state information (CSI) from one user equipment (UE) to another UE using a L1 signal. A first UE requests a CSI report from a second UE. The first UE sends a reference signal which the second UE measures to determine channel characteristics. The second UE forms a CSI report which includes a rank indicator, a channel quality indicator, and potentially a precoding matrix index indicator. The second UE forms the CSI report at the PHY level. The CSI report is included in reserved field(s) of a second stage sidelink control information (SCI-2). The first UE receives and processes the CSI report at a PHY level.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein relate to a user equipment (UE) that may include a wakeup radio in addition to a main radio to monitor for wakeup signals while the UE is in a sleep mode. The wakeup radio receiver may use less power than the main radio. In some examples, a first UE may indicate to a wireless node (e.g., a controlling sidelink UE or a network entity) that the UE is capable of sending wakeup signals to a second UE. In such examples, the wireless node may transmit a wakeup signal intended for the second UE to the first UE based on the capability report. The first UE may relay the wakeup signal to the second UE. Responsive to receiving the wakeup signal, the second UE may wake up the main radio of the second UE for communications.

Abstract: Methods, systems, and devices for wireless communications are described. The method, system, or devices for wireless communications may implement receiving a grant for a first transmission scheduled for a first set of resources, the first transmission associated with a first transmission parameter; receiving an indication to cancel the first transmission; dropping the first transmission based on receiving the indication; determining a second transmission parameter for a second transmission based on the first transmission parameter and irrespective of dropping the first transmission; and performing or receiving the second transmission according to the second transmission parameter. Alternatively, a device may receive an indication to cancel the second transmission; drop the second transmission based on receiving the indication; and refraining from rescheduling the first transmission on the first set of resources based on receiving the indication and irrespective of dropping the second transmission.

Abstract: A first UE may receive, from a second UE via a first sidelink, a first TB. The first TB may be associated with a first priority. The first UE may receive, from a third UE via a second sidelink, a second TB. The second TB may be associated with a second priority. The first UE may forward the first TB to a fourth UE and the second TB to a fifth UE via physical layer multiplexing over a third sidelink and a fourth sidelink, respectively, based on the first priority and the second priority. To forward the first TB to the fourth UE and the second TB to the fifth UE, the first UE may perform an AF operation or a DF operation.
