Abstract: Methods, systems, and devices for wireless communications are described for relayed sidelink communications in which a set of relays receives a groupcast sidelink communication from a source and relay the communication to a destination using cooperative multiple-input multiple-output (MIMO) techniques. A source, such as a source user equipment (UE), may reserve resources for the groupcast sidelink communication and the cooperative MIMO transmissions, and may transmit a resource reservation message with an indication of the reserved resources. The resource reservation message may be transmitted in a sidelink control information transmission, in a medium access control message, or any combinations thereof. In the event of a collision in reserved resources of multiple different sources, the sources or relays may determine a priority of each communication and transmit a selected communication based on the priority determination.

Abstract: Methods, systems, and devices for wireless communications are described. Wireless communications systems may employ one or more scheduling constraints to support efficient utilization of techniques for intra-device handling of overlapping scheduled uplink transmissions (e.g., intra-device dynamic resource cancelation and multiplexing) as well as inter-device handling of overlapping scheduled uplink transmissions (e.g., inter-device dynamic resource cancelation and multiplexing). Scheduling constraints may define how a device may apply intra-device and inter-device multiplexing and cancelation rules for various scenarios. For example, a device may apply intra-UE cancelation rules before inter-device cancelation rules. In some examples, later-received grants or uplink preemption indications (ULPIs) may not change a device's previously established decision to drop an uplink transmission.

The base station sends a reference signal to the target UE and sidelink UEs, and the target UE sends sidelink signals to each sidelink UEs. A range-sum for the range between the target UE and sidelink UE and the range between the sidelink UE and the base station can be determined for each sidelink UE, based on the time differences between the reception and transmissions of the reference signals measured by the target UE, and the time difference between reception of the reference signals measured by the sidelink UE. A differential in the range-sums can be determined and used to determine the position of the target UE.

Abstract: This disclosure provides systems, methods and apparatus, including computer storage media, for sidelink communications using partial symbols to reduce overhead of automatic gain control (AGC) and gaps. A transmitting user equipment (UE) maps a sidelink signal to a subset of resource elements in a frequency domain allocation defined via a comb for a first orthogonal frequency division multiplexing (OFDM) symbol. The transmitting UE performs an inverse discrete Fourier transform (IDFT) on the resource elements to generate a first time domain signal that includes a number of repetitions of a first waveform based on a structure of the comb. The transmitting UE transmits at least one repetition of the first waveform of the first time domain signal during at least a portion of the first OFDM symbol. A receiving UE performs AGC and a discrete Fourier transform on portions of the time domain signal.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to measure sidelink channel conditions for a group of UEs and transmit a report (e.g., a channel state information (CSI) report) to a base station indicating the sidelink channel conditions. The base station may transmit control information (e.g., group-common downlink control information (GC-DCI)) to the group of UEs triggering the UEs to transmit sidelink reference signals (e.g., CSI reference signals (CSI-RS)) on the sidelink channels so that the UE can measure the sidelink channel conditions and transmit the report. Based on the report, the base station may transmit control information (e.g., a downlink control information (DCI) message) scheduling sidelink communications for the group of UEs. In some examples, the UE may act as a relay node for the group of UEs, and forward control information to the group of UEs.
