摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE), served by a cell of a base station, may identify a time division duplexing (TDD) configuration for a first cell, wherein the TDD configuration includes a symbol pattern for a slot. The base station may determine an overlap between a downlink symbol or a flexible symbol and an uplink symbol during symbols of the slot based on a TDD configuration. A first UE may receive a configuration for transmitting a cross-link interference (CLI) sounding reference signal (SRS) to a second UE according to the configuration. The second UE may measure the CLI SRS and report the measurement.

摘要： User Equipment (UE) receives, from a base station (BS), at least one resource block (RB). The RB includes at least one reference signal (RS) resource element (RE) of a first physical channel of the UE. The UE estimates a channel quality of a second physical channel of the UE as a function of the at least one RS RE. In some examples, the BS associates the transmission of a first physical channel reference signal (RS) and the transmission of a second physical channel RS. The BS then signals, BS to the UE, the association between the first physical channel reference signal and the second physical channel reference signal.

摘要： Various aspects are described for schemes that address the potential puncturing of important reference signals (RSs) for enhanced mobile broadband (eMBB) applications, such as demodulation reference signal (DMRS), channel state information reference signal (CSIRS), tracking reference signal, and general reference signal. The schemes can be used for recovery of eMBB's RS puncturing from dynamic multiplexing of ultra-reliable-low-latency communications (URLLC) and eMBB. The schemes include a block-based scheme and an over-provisioning scheme. The schemes modify an existing RS pattern before puncturing occurs in response to a presence of the URLLC traffic. In addition, there can be an option not to use (e.g., disable) time-domain orthogonal cover code (TD-OCC) for the RSs.

摘要： A user equipment (UE) generates a positioning state information (PSI) report that is transmitted to a network entity in a lower layer channel container, e.g., in the Physical channel or Medium Access Control channel, to reduce latency. The PSI report may be generated based on a plurality of PSI report elements determined from positioning measurements performed by the UE. Each PSI report element includes information related to positioning measurements performed by the UE. One or more of the PSI report elements may be compressed based on a compression configuration, in order to reduce overhead. If the size of the PSI report elements, after one or more PSI report elements are compressed, is larger than the lower layer channel container, one or more of the PSI reports may be omitted from the PSI report. A network entity may receive and process the PSI report based on the compression configuration.

摘要： A user equipment (UE) generates a positioning state information (PSI) report that is transmitted in a lower layer channel container, e.g., in the Physical channel or Medium Access Control channel, to a network entity to reduce latency. For example, the PSI report is generated based on a plurality of PSI report elements determined from uplink (UL), downlink (DL) or UL and DL positioning measurements. Each PSI report element includes information related to positioning measurements performed by the UE. The PSI report elements are ordered, e.g., from highest priority to lowest priority, according to priority based rules. If the size of the PSI report elements is larger than the lower layer channel container, one or more of the low priority PSI report elements are omitted from the PSI report. A network entity may receive and process the PSI report based on the same priority based rules.

摘要： Disclosed are techniques for wireless communication. In an aspect, a PRS sequence is determined based in part on a sidelink zone where a transmitting UE is located. A receiving UE may perform a blind search based on PRS sequence(s) associated with its own sidelink zone and/or neighboring sidelink zones. In other aspects, measurement reports may be conveyed to a position estimation entity with positioning measurements being associated with respective PRS sequences, which can then be correlated to the respective transmitting UEs at the position estimation entity so as to facilitate position estimation of a target UE.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may precode sounding reference signals using an interference covariance matrix to report channel quality information to a base station. For example, a UE may receive an indication of a future time from a base station. The future time may correspond to a future time for which the UE may predict an interference covariance matrix. In some cases, based on receiving the indication, the UE may monitor for interference in one or more interference measurement resources. In some examples, the UE may then determine the predicted interference covariance matrix and may transmit a sounding reference signal to the base station. The sounding reference signal may be precoded based on the predicted interference covariance matrix. In some cases, the UE may receive a downlink signal from the base station at the future time or at a second time.
