Abstract: A method and apparatus enable sidelink resource management using a sidelink discovery signal. The method provides for determining a resource configuration for a sidelink discovery signal. The resource configuration provides one or more parameters for transmitting the sidelink discovery signal. The method also provides for measuring link quality between the UE and at least one candidate relay UE. Based on the measured link quality one of the candidate relay UEs is selected and serves as a relay UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication that a high Doppler configuration is activated. The UE may detect, based at least in part on receiving the indication that the high Doppler configuration is activated, a phase tracking reference signal (PTRS) for a remaining minimum system information (RMSI) communication. The PTRS may be configured by the high Doppler configuration. Numerous other aspects are provided.

Abstract: To more efficient sidelink communications, methods, apparatuses, and computer program products are provided. An example method of a first wireless device operating includes transmitting a sidelink discovery probing message comprising at least a first identifier of the first sidelink device. The example method further includes monitoring for a probing response from a second sidelink device. The example method further includes transmitting a sidelink discovery message if the first sidelink device receives the probing response from the second sidelink device. The example method further includes skipping transmitting the sidelink discovery message if the first sidelink device does not receive the probing response from the second sidelink device.

Abstract: Wireless communications systems may support flexible waveform configuration for autonomous uplink transmissions. A base station may transmit broadcast signaling (e g , a system information block (SIB)) indicating waveform configuration information for an autonomous uplink transmission by a user equipment (UE). In some cases, the broadcast signaling may include a waveform configuration field (WCF) that may indicate whether flexible waveforms for autonomous uplink are supported, may configure a waveform type, may indicate waveform configuration mapping rules, etc. As such, a UE may identify whether flexible waveform configuration for autonomous uplink is supported, and may determine waveform types for autonomous uplink transmissions based on waveform type configuration information from a base station (e.g., which may include an indication of whether flexible waveform configuration is supported, an indication of waveform type/scenario mapping rules, etc.), one or more LUTs, identified autonomous uplink scenarios, autonomous uplink transmission parameters, or some combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a physical random access channel (PRACH) preamble. At least one property associated with the PRACH preamble corresponds to a request for repetition of Msg3. Accordingly, the UE may transmit, to the base station and based at least in part on the random access preamble, two or more repetitions of a Msg3. Numerous other aspects are provided.

Abstract: In an aspect, a UE determines a power consumption of the UE for a position estimation procedure based on a set of power consumption parameters associated with the UE, the set of power consumption parameters comprising one or more layer-specific parameters associated with a set of positioning frequency layers (PFL), a Positioning frequency layer processing capability of the UE, a positioning reference signal (PRS) resource processing capability of the UE, a PRS measurement type capability of the UE, a positioning session processing capability of the UE, or a combination thereof. The UE performs one or more positioning measurements associated with the position estimation procedure in accordance with the determined power consumption.

Abstract: Wireless communication devices are adapted to facilitate a random access procedure. According to one example, scheduled entity can transmit a first transmission that is received by a scheduling entity. The first transmission may include a physical random access channel (PRACH) preamble sequence and a first message including information for determining a device-specific network identifier for the scheduled entity. The scheduling entity may transmit a second transmission that is received by the scheduled entity. The second transmission may include information on a physical downlink control channel (PDCCH) addressed to the device-specific network identifier for the scheduled entity, and a second message on a physical downlink shared channel (PDSCH). Other aspects, embodiments, and features are also included.

Abstract: A configurable new radio (NR) RACH procedure that may be executed by a UE and a base station is disclosed. A configuration to determine, by a user equipment, a random access procedure timeline, from multiple random access procedure timelines that each define a different duration between one or more messages that are communicated in a random access procedure can be determined or transmitted. A random access preamble can be received from the UE based on the random access procedure timeline, and a response to the random access preamble can be determined or transmitted based on the random access procedure timeline.

Abstract: A method of wireless communication by a base station includes configuring a tracking reference signal (TRS) with respect to a physical downlink shared channel (PDSCH) for an idle/inactive mode user equipment (UE). The method also transmits the tracking reference signal and the PDSCH during a paging cycle, in accordance with the configuration. A method of wireless communication by a UE includes expecting a TRS to be received when a PDSCH is received.
