Abstract: This disclosure provides methods, devices and systems for facilitating device-to-device (D2D) communications on sidelinks. Some implementations more specifically relate to a user equipment (UE) determining sidelink communication parameter corresponding to UE assistance information or UE capability information. The UE may also determine an attribute associated with the sidelink communication parameter, the attribute indicating the sidelink communication parameter is a dynamic parameter or a static parameter. The UE may further transmit to another UE, on a sidelink, the sidelink communication parameter and the attribute. The UE may also communicate with the other UE on the sidelink based on the transmitted sidelink communication parameter and the attribute.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication over a sidelink between a first user equipment (UE) and a second UE. The first UE may receive, from a base station, a first sidelink grant for a transmission between the first UE and the second UE. The first UE may communicate the transmission according to the sidelink grant. The first UE may monitor a configured duration of a sidelink round trip time timer from the transmission. The first UE may monitor a configured duration of a sidelink retransmission timer from an end of the sidelink round trip time timer. The first UE may allow start of a discontinuous reception (DRX) mode after the duration of the sidelink retransmission time if a second grant is not received during the sidelink retransmission timer.

Abstract: A method of wireless communications by a sidelink UE (user equipment) includes receiving a first signal as part of a discontinuous reception (DRX) wake-up procedure at the beginning of a sidelink discontinuous reception (DRX) ON duration. The method also includes transmitting a response to the first signal as part of a DRX wake-up procedure. The method further includes starting a timer after sending the response. The method still further includes entering a sleep state upon not receiving a physical sidelink control channel (PSCCH) or physical sidelink shared channel (PSSCH) before the timer expires.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform a physical layer measurement on a non-serving cell of the UE. The UE may report a measurement value of the physical layer measurement to a serving cell of the UE based at least in part on the physical layer measurement satisfying a threshold. The UE may receive, based at least in part on reporting the physical layer measurement, a physical layer reference signal measurement configuration for the non-serving cell. The UE may transmit a measurement report based at least in part on the physical layer reference signal measurement configuration. Numerous other aspects are provided.

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: Certain aspects of the present disclosure provide techniques for selecting and indicating a quasi colocation (QCL) source signal for sidelink (SL) communications. For example, a scheduling node may select from multiple candidates a signal for a first user equipment (UE) to use as a spatial QCL source for a receive (RX) or transmit (TX) beam to use for communicating with a second UE on a SL interface. The scheduling node may then signal the first UE an indication of the selection of the signal.

Abstract: Techniques for dynamic sidelink waveform selection are disclosed. In an example, a user equipment (UE) may determine capabilities of the UE and at least one other UE. The UE may also dynamically select a waveform for sidelink beam training based on the capabilities. The UE may also communicate with the at least one other UE based on the selected waveform.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication over a sidelink between a first user equipment (UE) and a second UE. The first UE may receive, from a base station, a sidelink resource configuration indicating physical sidelink control channel (PSCCH)/physical sidelink shared channel (PSSCH) occasions on which to monitor a PSCCH for a grant from a second UE. The first UE may determine an active time for monitoring the PSCCH based on a discontinuous reception (DRX) mode for a link with the base station, the DRX mode including an active state in which a physical downlink control channel (PDCCH) is monitored and an inactive state in which the PDCCH is not monitored. The first UE may monitor the PSCCH during one or more of the PSCCH/PSSCH occasions that coincide with the active time.

Abstract: Certain aspects of the present disclosure provide techniques for dynamically scheduling antenna resources of a wireless node, such as, antenna panels of a user equipment (UE). In some cases, a first node (e.g., a UE) performs, with two or more other nodes, a first beam sweep procedure across two or more antenna resources of the first node on two or more wireless interfaces, generates or obtains scheduling information based on results of the first beam sweep procedure, wherein the scheduling information indicates which of the antenna resources is scheduled for which wireless interfaces, and communicates with the other nodes on the wireless interfaces according to the scheduling information.

Abstract: A method of wireless communication, by a first sidelink user equipment (UE), includes periodically receiving a set of sidelink beam failure detection reference signals (RSs) from a second sidelink UE. The method includes incrementing a beam failure detection (BFD) counter in response to one or more reference signals of the set of sidelink beam failure detection RSs having a received signal strength below a threshold. The first sidelink UE starts a beam failure detection timer in response to the reference signal(s) of the set of sidelink beam failure detection reference signals having the received signal strength below the threshold. Another method by a sidelink UE may periodically transmit a set of sidelink BFD RSs to another sidelink UE. The set of sidelink BFD RSs comprise one or more sidelink receive RSs. The sidelink UE configures the other sidelink UE with the sidelink receive BFD RSs.
