摘要： Sounding reference signals (SRS) transmitted by a UE, e.g., for positioning or channel estimation, may be configured for one or both of frequency tone level cyclic shift and symbol level code, which, for example, enables multiplexing a greater number of UEs. The frequency tone level cyclic shift is produced by jointly processing a number of symbols with an extended cyclic shift structure. The SRS may be configured using a symbol group level that indicates the number of symbols associated with a cyclic shift structure, and an outer code that indicates a multiplier applied to the SRS at the symbol level, which increases the multiplexing opportunities. The symbol level code may further indicate an extended cyclic shift indicating a linear increase in phase rotation across tones in symbols associated with the symbol group level.

摘要： Various embodiments include methods for demodulating wireless transmission waveforms to reconstruct data tones, performed in receiver circuitry of a wireless communication device. The methods may include receiving time domain wireless transmission waveforms that include time domain peak reduction tones (PRTs) that were generated by a set of PRT neural networks using time domain data signals derived from frequency domain data tones in another wireless communication device, reconstructing the time domain data signals from the time domain wireless transmission waveforms using a receiver neural network that has been trained in conjunction with the set of PRT neural networks to generate a time domain reconstruction of data signals, and transforming the time domain reconstruction of data signals to a frequency domain reconstruction of data tones.

摘要： Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas associated with different power classes. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. The local and auxiliary antennas may be associated with different power classes, and the first device may transmit a message to a base station indicating that the first device is capable of transmitting using antennas associated with different power classes. The first device may then receive configurations from a base station of different transmit powers to transmit on the antennas associated with the different power classes, and the first device may transmit uplink signals to the base station in accordance with the different transmit power configurations.

摘要： Wireless communication devices, systems, and methods related to mechanisms to implement improved interference tracking over time. A BS may transmit information to a UE that allows the UE to quantize channel measurements into interference states. The UE may transmit an interference change report as triggered by an event, such as an interference metric exceeding a threshold after quantizing into the interference states. This enables the system to capture and respond to abrupt changes. Further, the interference change report may include historic interference information. The UE may include statistics based on the historic interference information. The UE may further be triggered to transmit an interference change report in response to a BS requesting it, or in response to a configured period of time elapsing. The UE may further include MCS information predicted for one or more future time periods based on historic information, which the BS may use in scheduling.

摘要： Disclosed are techniques for signaling of reception-to-transmission measurements from gNBs and user equipments (UEs) for round trip time (RTT) based positioning in wireless networks such as new radio (NR). In multi-RTT positioning, the flow of messages that are exchanged differ depending on the entity acting as the location server determining the position of the UE.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a grant for a communication with the base station. The UE may determine whether the communication is associated with a hybrid automatic repeat request (HARQ)-based transmission mode or a HARQ-less transmission mode. The UE may communicate with the base station based at least in part on the grant and the determination of whether the communication is associated with the HARQ-based transmission mode or the HARQ-less transmission mode. Numerous other aspects are described.

摘要： Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) and a network entity may support a configured grant (CG)-specific retransmission timer configuration based on a traffic type to be communicated using a given CG. For example, the network entity may indicate a CG for uplink transmissions and may indicate a retransmission timer that is specific to the CG. As such, the UE may transmit a data message in accordance with the CG and may select a time period during which to monitor a downlink control channel for control information indicating a retransmission request for the data message in accordance with a value of the retransmission timer. Additionally, or alternatively, the UE and the network entity may support a downlink-to-uplink configuration dependency for determining an uplink periodicity of a CG based on a downlink periodicity.

摘要： Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may receive, from a network entity, a request to provide an enhanced positioning measurement report comprising a positioning measurement and further comprising a report of components of a channel power delay profile (PDP), a report of a probability distribution of times of arrival (ToA), or both. The UE may determine an enhanced measurement period required by the UE to perform the enhanced positioning measurement, wherein the enhanced measurement period is longer than a standard measurement period required by the UE to perform a non-enhanced positioning measurement. The UE may perform the enhanced positioning measurement using the enhanced measurement period. The UE may provide the enhanced positioning measurement report to the network entity.

摘要： Methods, systems, and devices for wireless communications are described. A configuration for a reference signal used to determine a non-linear behavior of transmission components at a transmitting device may be determined. The configuration for the reference signal may be determined based on signaling transmitted by the transmitting device, signaling transmitted by a device that receives the reference signal, or both. Additionally, or alternatively, the configuration for the reference signal may be determined based on a configuration of other signals transmitted by the transmitting device prior to or concurrently with the transmission of the reference signal. The determined configuration may be used to generate and transmit the reference signal or to determine a configuration of a received reference signal. In both cases, a non-linear response of transmission components at the transmitting device may be determined based on the reference signal.
