摘要： Certain aspects of the present disclosure relate to methods and apparatus mapping virtual resource blocks (VRBs) to physical resource blocks (PRBs) and using the mapping in wireless communications, for example, in new radio (NR) technologies. An exemplary method includes determining a first interleaved mapping that maps a first interleaving unit of N consecutive first virtual resource blocks (VRBs) to N consecutive first physical resource blocks (PRBs), wherein each first PRB comprises a set of frequency resources during a period, transmitting a first grant allocating the first interleaving unit of first VRBs to a first user equipment (UE), and communicating with the first UE via the first PRBs mapped to the first VRBs of the first interleaving unit.

摘要： This disclosure provides systems, methods, and devices for wireless communication that provide managing transmissions of sidelink positioning reference signals (PRS) with a timing advance offset (TA) from a sidelink node. In aspects, a sidelink node (e.g., a target user equipment (UE) or an assisting UE) may receive transmissions from a plurality of nodes (e.g., target UEs or assisting UEs). The sidelink node obtains at least one TA to be used by a transmitting node of the plurality of nodes for transmitting a sidelink PRS to the sidelink node (e.g., to advance the sidelink PRS transmission to the sidelink node with respect to the timing of the first transmission). The TA is an offset obtained by the sidelink node based on the receiving times of the transmissions from the plurality of nodes. The sidelink node may receive PRS transmissions from the plurality of nodes in a same symbol aligned within the same CP.

摘要： In an aspect, a first BS measures a SRS-P associated with a RTT measurement procedure between a UE and a second base station, and reports measurement information based on the measurement of the SRS-P. In another aspect, a device (e.g., UE, BS, LMF, etc.) obtains the measurement information along with measurement information based on measurements at the UE and the second base station, and determines a positioning estimate of the UE based on the first, second and third measurement information.

摘要： Methods, systems, and devices for wireless communications are described. A transmitting user equipment (UE) may receive different configurations for determining a first transmit power for data transmissions and a second transmit power for energy harvesting transmissions. The different configurations may include different parameters for determining (e.g., calculating) the first transmit power and the second transmit power. In some aspects, the transmitting UE may also receive an indication of the second transmit power from a receiving UE such that the second transmit power may be determined in accordance with the capabilities of the receiving UE (e.g., based on an energy harvesting circuit at the UE). The indication of the second transmit power may be an indication of one or more parameters used to determine (e.g., calculate) the second transmit power.

摘要： An apparatus for wireless communication includes a receiver configured to receive, from a device, a charging signal that is based on one or more time domain taps and that is associated with a data signal. The apparatus further includes a transmitter configured to transmit, to the device, a feedback signal associated with the charging signal. The feedback signal indicates at least one parameter that is detected by the apparatus and that is associated with the one or more time domain taps. Other aspects and features are also described.

摘要： Disclosed are methods and apparatuses for resolving aliasing ambiguities produced when using channel state information reference signal, a sounding reference signal (SRS) or other transmission as a positioning reference signal (PRS) occupying a subset of tones of a PRS bandwidth. The aliasing ambiguity results in a plurality of different possible positioning measurements, such as time of arrival (TOA), reference signal timing difference (RSTD), or reception to transmission difference (Rx−Tx). The aliasing ambiguity may be resolved using a previous position estimate that may be used to produce an approximation of the expected positioning measurement. A position estimate may be generated using a multiple stage PRS configuration, in which one or more stages provide a coarse position estimate that has no ambiguity, which can be used to resolve the ambiguity of a more accurate position estimate resulting from the PRS signal.

摘要： Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) configured to operate in discontinuous reception (DRX) mode receives a configuration of a plurality of DRX groups, receives one or more positioning reference signal (PRS) configurations for the plurality of DRX groups, each of the one or more PRS configurations indicating one or more PRS resources for each of the plurality of DRX groups, receives one or more wakeup signals (WUS) for the plurality of DRX groups, the one or more WUS indicating whether or not the UE is expected to wake up for a next DRX cycle of each of the plurality of DRX groups, and measures/transmits the one or more PRS resources for each of the plurality of DRX groups during the next DRX cycle of each of the plurality of DRX groups based, at least in part, on the one or more WUS.

摘要： Certain aspects of the present disclosure provide techniques for avoiding transmission configuration indication (TCI) reselection (e.g., due to some bandwidth part (BWP) switching scenarios). An exemplary method generally includes configuring a UE with TCI state information for communication via multiple BWPs, wherein the TCI state information indicates quasi co-location (QCL) assumptions of at least first and second types and determining whether to reconfigure the TCI state of the UE to reflect a BWP switch, based on one or more rules that define BWP switching for reference signals (RSs) of at least one of the QCL assumption types without TCI state reconfiguration. Other aspects and embodiments are also claimed and described.

摘要： Techniques are provided for utilizing positioning reference signals (PRS) in full duplex scenarios. An example method for wireless communication by a user equipment (UE) includes receiving a positioning reference signal in a time slot, wherein the positioning reference signal spans a first frequency bandwidth, transmitting a signal in a second frequency bandwidth during the time slot, wherein the second frequency bandwidth includes frequencies within the first frequency bandwidth, and processing the positioning reference signal received in the first frequency bandwidth excluding the frequencies in the second frequency bandwidth.
