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: Techniques, systems, and devices for wireless communications are described. A user equipment (UE) may be in communication with a first and second transmitting device (e.g., by sidelink communication links). The UE may receive, from the first transmitting device, a first reference signal on a first set of resources. The UE may additionally receive, from the second transmitting device, a second reference signal on a second set of resources that overlap in the time domain with the first set of resources. In some cases, the first and second set of resources may additionally overlap in the frequency domain. The UE may determine synchronization information for time tracking or frequency tracking of sidelink communications with the first and second transmitting devices based on the first and second reference signals. The UE may communicate with the first and second transmitting devices based on the synchronization information for time tracking or frequency tracking.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be scheduled for communicating a first message over a first communication link with a base station and a second message over second communication link with a second UE. The first UE may select to communicate using the first communication link or the second communication link based on one or more prioritization rules that may involve the priority of the first message and the second message. The first UE may identify a mapping between the priority of the first message and the priority of the second message that may enable a comparison of the priorities of the first message and the second message. The first UE may select to communicate using the communication link of the message associated with the higher priority.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for determining shared resources associated with one or more user equipments (UEs) for sidelink communications, including control resources and data resources. A first UE may determine a first set of control resources in a first frequency band corresponding to a first group of UEs including the first UE. The first UE may transmit a sidelink request to reserve a subset of data resources to a second UE in the first group of UEs. The first UE may monitor for one or more sidelink responses indicating a positive sidelink response to the sidelink request, a negative sidelink response to the sidelink request, or both. The first UE may determine, based on monitoring for the one or more sidelink responses, whether to transmit a sidelink confirmation indicating a reservation of the data resources to the second UE.

Abstract: Methods, systems, and devices for wireless communications are described. A device may be configured to support multi-beam, or multi-panel operations, or both which may allow multiple sidelink transmissions to occur simultaneously. In some cases, flexible beam-management for the beamformed sidelink communications is implemented to manage the beams. A transmitting UE may indicate transmission beam information to the base station that the base station may use to schedule sidelink transmissions as part of a beam management procedure. The beam management procedure may allow a transmitting UE to update transmission beam information based on the mobility of the sidelink UEs and other environmental factors. In some cases, beam management includes a beam training procedure that may be implemented to refine the sidelink beams, where support for multi-panel and multi-beam operation may allow for multiple beams to be trained simultaneously.

Abstract: Methods, systems, and devices for wireless communications are described. For example, the described techniques provide for configuring sidelink beam failure detection reference signals for determining beam failures on a sidelink between a first sidelink user equipment (UE) and a second sidelink UE. The first UE may determine a first set of sidelink beam failure detection reference signals to transmit to the second UE and a second set of sidelink beam failure detection reference signals to receive from the second UE. The first UE may transmit the first set to the second UE using a set of sidelink transmit beams. The first UE may further monitor for the determined second set using a set of sidelink receive beams. Based on the first and second set of sidelink beam failure detection reference signals, the first and second UE may communicate over the sidelink.

Abstract: A method of wireless communication by a first sidelink user equipment (UE) transmits a sidelink (SL) beam failure recovery (BFR) message to a communications node, indicating a new candidate beam and an identifier (ID) of a second sidelink UE. The method also receives an acknowledgment of the SL BFR message. A communications node receives a sidelink beam failure recovery message from a first sidelink user equipment, indicating a new candidate beam and an ID of a second sidelink UE. The method also transmits information identifying the new candidate beam and the ID to the second sidelink UE. Another method by a first sidelink user equipment receives a sidelink beam failure recovery message from a base station, indicating a new candidate beam and an ID of a second sidelink UE. The method changes a beam used to communicate with the second sidelink UE in response to receiving the BFR message.

IPC: H04W56/00
Abstract: Methods, systems, and devices for wireless communications are described. Sidelink UEs may be configured with a synchronization reference signal that may be used by the UEs to synchronize time and frequency resources. A first and second UE may perform a beam sweeping procedure to identify transmit and receive beams to use for communications between the UEs. A synchronization reference signal procedure may be initiated and the first UE may receive a sidelink synchronization reference signal from the second UE using the established receive beam. The UEs may align time and frequency resources for communications between the UEs and the UEs may communicate via the sidelink channel based on the time synchronization, frequency synchronization, or both, determined using the sidelink synchronization signal. In some cases, a sidelink UE may receive multiple synchronization reference signals from multiple sidelink UEs simultaneously, where each synchronization reference signal may include a UE identifier.

The first UE may determine, based on monitoring for the one or more sidelink responses, whether to transmit a sidelink confirmation indicating a reservation of the subset of the data resources to the second UE.
