Abstract: Disclosed are techniques for determining tone patterns and associated power levels for transmission of reference signals. A tone pattern (e.g., with each tone pattern occupying a resource element in a resource block) can be determined for a reference signal for use in wireless communications between a receiving device and a transmitting device. A plurality of power levels for the tone pattern can be determined. The plurality of power levels can include a respective power level determined for each resource element associated with the tone pattern. One or more of the tone pattern or the plurality of power levels can be used (e.g., transmitted to the transmitting device) for transmission of the reference signal (e.g., from the transmitting device to the receiving device).

Abstract: Disclosed are techniques for determining tone patterns and associated overlay codes for transmission of reference signals. A tone pattern (e.g., with each tone pattern occupying a resource element in a resource block) can be determined for a reference signal for use in wireless communications between a receiving device and a transmitting device. The tone pattern can include an irregular combination of resource elements in one or more resource blocks for the reference signal. The resource elements can be shared by a plurality of antennas for communication of one or more reference signals between at least the user equipment and the base station. An overlay code may be determined for the tone pattern. Information associated with the transmission of the reference signal using the tone pattern and the overlay code may be communicated by the receiving device.

Abstract: Certain aspects of the present disclosure provide techniques for sidelink assisted retransmissions, in which a first UE obtains first data intended for a second UE by decoding a first transmission of the first data targeting the second UE, receives signaling indicating the first UE is to retransmit the first data to the second UE, and retransmits the first data to the second UE, via a sidelink, in response to the signaling.

Abstract: Methods, systems, and devices for wireless communications are described. A target user equipment (UE) may communicate (e.g., transmit, receive) a message indicating a relay UE for relaying wireless communications between the target UE and a base station. The relay UE is selected from a set of candidate relay UEs based on existing sidelink relay communication links at the relay UE, candidate target UEs associated with the relay UE, existing communication sidelinks between the target UE and the candidate relay UEs, or any combination thereof. The target UE may receive a first control signal indicating a sidelink relay communication link for communicating messages between the first UE and the base station via the relay UE, and receive a second control signal activating the sidelink relay communication link. The target UE may then communicate a message to or from the base station via the relay UE and the sidelink relay communication link.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a sidelink user equipment (UE) may monitor a set of symbols over a wireless channel. The set of symbols may include at least a first subset of symbols and a second subset of symbols. A quantity of symbols included in the first subset of symbols may be based on a carrier frequency of the wireless channel, a symbol length of the wireless channel, a subcarrier spacing (SCS) of the wireless channel or a capability of the sidelink UE. Further, the sidelink UE may receive a sidelink transmission over the second subset of symbols, where a starting position of the second subset of symbols is defined according to the quantity of symbols included in the first subset of symbols

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may provide, to a sidelink UE, discontinuous reception (DRX) configuration information for sidelink communications with the sidelink UE, wherein the DRX configuration information indicates a channel busy ratio (CBR) configuration of the UE. The UE may receive, based at least in part on the DRX configuration information, a communication from the sidelink UE, wherein one or more parameters associated with the communication are based at least in part on the CBR configuration of the UE. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive control signaling indicating a set of component carriers allocated for sidelink communications performed by the first UE. The first UE may receive a message indicating a subset of component carriers from the set of component carriers for use in communicating via a sidelink between the first UE and a second UE, where the subset of component carriers may be supported by the first UE and the second UE. In some cases, a base station or anchor UE may determine or configure the subset of component carriers for use between the first and second UEs. In some cases, the first UE, the second UE, or a both may determine the subset of component carriers. The first UE may communicate with the second UE via a component carrier from the subset of component carriers.

Abstract: Systems, methods, and devices for wireless communication that support resource selection and indication for sidelink demodulation reference signal (DMRS) bundling. A transmitting UE determines sidelink resources for bundling a sidelink DMRS transmission to be transmitted to a receiving UE. In sidelink mode 1, the sidelink resources may be determined based on indications from a base station, which may include whether the transmitting UE is to maintain phase continuity over the sidelink resources during the bundling, or whether the transmitting UE is to include a phase jump reference signal with the bundled DMRS transmission to the receiving UE. In sidelink mode 2, the transmitting UE may select the sidelink resources based on the phase continuity capabilities of the transmitting UE and/or of the receiving UE, and/or based on a sensing of the sidelink channel. In some cases, the receiving UE may provide a resource recommendation to the transmitting UE.

Abstract: Aspects relate to mechanisms for a wireless communication device to configure and indicate one or more beams for sidelink communication with another wireless communication device. The sidelink communication can include first stage sidelink control information (SCI) and second stage SCI that may be communicated on a first beam configured on the wireless communication devices. The sidelink communication can further include sidelink data traffic that may be communication on a second beam. The second beam may be the first beam or a different beam based on at least one of a beam capability of at least the first wireless communication device or a gap between the sidelink data traffic and at least one of the first stage SCI or the second stage SCI.

Abstract: In an embodiment, a transmission reception point (TRP) apparatus of a Coordinated Multipoint (CoMP) network, determines a periodicity of periodic traffic between the TRP apparatus and a user equipment (UE), and schedules a Channel State Information (CSI) process in advance of a traffic window for a next instance of the periodic traffic in accordance with the determined periodicity. In another embodiment, the UE of the CoMP network performs the CSI process in advance of the traffic window for the next instance of periodic traffic between the UE and the TRP apparatus, the CSI process being scheduled in accordance with the determined periodicity of the periodic traffic.
