Abstract: Certain aspects of the present disclosure provide techniques for multiplexing HARQ feedback in a same slot for downlink and sidelink transmissions. An example method generally includes receiving, from a network entity, a downlink control information (DCI) that schedules resources for at least one physical sidelink shared channel (PSSCH) transmission from the first UE to a second UE, transmitting data to the second UE via the at least one PSSCH transmission using the scheduled resources, receiving, from the second UE, acknowledgment feedback for the at least one PSSCH transmission, selecting at least one codebook entry for providing feedback for at least one downlink transmission from the network entity to the first UE and the acknowledgment feedback for the at least one PSSCH transmission in a same physical uplink control channel (PUCCH) slot, and transmitting the at least one codebook entry to the network entity via at least one PUCCH transmission.

Abstract: Various aspects of the disclosure relate to the selection and use of modulation and coding scheme (MCS) values. For example, a first MCS table may be used for a first condition and a second MCS table used for a second condition. The disclosure relates in some aspects to inter-device signaling that indicates which MCS table is to be used for communication between the devices.

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 receive a sidelink communication on a sidelink between the UE and another UE. The UE may transmit, on the sidelink, one or more feedback communications associated with the sidelink communication in a reporting period having a configurable periodicity and/or being configured to occupy an entire bandwidth of a resource pool configured for the sidelink. Numerous other aspects are provided.

Abstract: Aspects relate to managing a device-to-device communication link via radio resource control (RRC) layer signaling. In an example operation, a first wireless communication device establishes a unicast link with a second wireless communication device over a device-to-device communication interface and determines that the unicast link is to be reconfigured with at least one updated parameter. The first wireless communication device then sends a link reconfiguration request to the second wireless communication device via a first RRC message over the communication interface. The first RRC message includes the at least one updated parameter. The first wireless communication device receives a link reconfiguration response from the second wireless communication device via a second RRC message over the communication interface based on the link reconfiguration request and determines whether to reconfigure the unicast link using the at least one updated parameter based on the received link reconfiguration response.

Abstract: In one example, a method being performed by a first station and comprises: transmitting a first message including an indication of whether a clock reconfiguration event occurs at the first station; transmitting a first positioning reference signal (PRS); receiving from a second station a second PRS; and transmitting to the second station a second message including a first time when the first PRS is transmitted by the first station and a second time when the second PRS is received by the first station, to enable the second station to determine a roundtrip time (RTT) between the first station and the second station based on the first time, the second time, a third time when the second station receives the first PRS, a fourth time when the second station transmits the second PRS, and the indication.

Abstract: A method, a computer-readable medium, and an apparatus are provided. The apparatus communicates with a second apparatus, including transmitting or receiving a first transmission. The apparatus receives information about the second UE from a sensor at the first UE and/or from a BSM. The apparatus determines whether the first apparatus and the second apparatus are in a LOS condition based on a correlation of the information with one or more of a channel estimation, PMI feedback, or RI feedback. The apparatus may adapt a transmission parameter for a second transmission based on a predicted location of the first apparatus or the second apparatus. The transmission parameter may include at least one of a modulation, a code rate, a DMRS density, a precoder, a CSI-RS transmission periodicity or a feedback rate.

Abstract: Aspects of the present disclosure provide synchronization techniques for user equipment (UEs) that may be otherwise unable to support sidelink communication a synchronized UE and may have also lost global navigation satellite system (GNSS) and/or Evolved Node Base Stations (eNBs) as a synchronization source. In such instance, the unsynchronized UE may utilize reference signals (RS) from the data packets received from other UEs to track the timing and perform autonomous timing adjustments based thereon for synchronized packet transmission or reception.
