Abstract: Certain aspects of the present disclosure provide techniques for transmitting and processing channel state information (CSI) reference signals (CSI-RS). An exemplary method includes determining a configuration of channel state information reference signals (CSI-RSs), wherein the configuration indicates a set of resource elements (REs) to be used for CSI-RSs and a first mapping of CSI-RS ports to the set of REs; sending an indication of the configuration of the CSI-RSs; and transmitting the CSI-RSs according to the determined configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A device (e.g., a base station or a user equipment (UE)) may identify a sequence length corresponding to a number of resource blocks, and select a modulation scheme based on the sequence length. The device may select, from a set of sequences associated with the modulation scheme, a sequence having the sequence length. In some examples, the set of sequences may include at least one of a set of time domain phase shift keying computer-generated sequences or a set of frequency domain phase shift keying computer-generated sequences. The device may generate a reference signal for a data transmission based on the sequence and transmit the reference signal within the number of resource blocks.

Abstract: Disclosed are techniques for determining a position of a user equipment (UE). A differential round-trip-time (RTT) based positioning procedure is proposed to determine the UE position. In this technique, the UE position is determined based on the differences of the RTTs between the UE and a plurality of base stations. The differential RTT based positioning procedure has much looser inter-gNodeB timing synchronization requirements than the OTDOA technique and also has much looser group delay requirements than traditional RTT procedures.

Abstract: Certain aspects of the present disclosure provide techniques for channel estimation for two-stage sidelink control using sidelink data channel demodulation reference signals (DMRS). A user equipment (UE) can transmit DMRS for the sidelink data channel. The UE may transmit the second stage of the sidelink control using antenna ports or a precoder used for the sidelink data channel. The receiving device may receive the DMRS, estimate the channel, and demodulate the second stage of the sidelink control based on the estimated channel. The receiving device may flexibly determine the DMRS to use for the estimation and demodulation.

Abstract: Disclosed are techniques related to wireless communication system in which a network node is allowed to puncture a reference signal (RS) to deliver high priority data (e.g., URLLC data) to a user equipment (UE) that is not currently being served by the network node. In an aspect, the RS comprises a puncturable subset and an unpuncturable subset. In an aspect, the puncturable subset comprises resources of the RS that are allowed to be punctured, and the unpuncturable subset comprises resources of the RS that are prohibited from being punctured. In an aspect, the network node transmits the RS such that unpuncturable subset indicates whether or not the puncturable subset of the RS has or has not been punctured.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a base station transmitting a modulation and coding scheme index corresponding to a modulation and coding scheme table to a user equipment (UE). The modulation and coding scheme index may be applied to encoding or decoding a transport block. The modulation and coding scheme may be associated with at least two modulation orders or a differential indication according to a modulation and coding scheme table. To determine which of the modulation orders for processing the transport block, the UE and the base station may use a prior modulation order associated with a prior transmission of the transport block. The UE may process the transport block by encoding or decoding the transport block based at least in part on the determined modulation order.

Abstract: In an aspect, a wireless node (e.g., UE, gNB) performs a partial measurement of a measurement type (e.g., RSTD, Rx-Tx, etc.) of a reference signal for positioning (RS-P) resource (e.g., PRS, SRS) that includes multiple symbols, the partial measurement being measured across a subset of the multiple symbols. The wireless node transmits a measurement report that includes an indication of the first partial measurement. The communications device receives the measurement report, and determines whether a spoofing attack is associated with the RS-P based at least in part upon the measurement report.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) performs one or more positioning measurements of positioning reference signals (PRS) transmitted by at least one set of transmission-reception points (TRPs) of one or more sets of TRPs, wherein each set of TRPs of the one or more sets of TRPs satisfies a dilution of precision (DOP) threshold, and reports the one or more positioning measurements or location information derived from the one or more positioning measurements.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for prioritizing, at a user equipment (UE), sidelink CSI reports received from other UEs. In one example, the UE may be configured to transmit sidelink CSI reports (e.g., received from other UEs) separately from other CSI reports (e.g., CSI reports generated by the UE), and the UE may prioritize sidelink CSI reports for transmission based on the priorities of the UEs from which the CSI reports are received. The UE may then aggregate and transmit the prioritized sidelink CSI reports to a network entity. In another example, the UE may be configured to transmit sidelink CSI reports with other CSI reports in a same channel, and the UE may prioritize the sidelink CSI reports over the other CSI reports for transmission to a network entity.
