Abstract: 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. 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 performed by the UE. Each PSI report element includes information related to positioning measurements performed by the UE. The transmission of at least one PSI report element generated by the UE may be postponed and not included in a current PSI report. The PSI report includes one or more indications of postponement, indicating that one or more PSI report elements have been postponed. A serving base station may grant a lower layer channel container for a second PSI report to contain the previously postponed PSI report elements.

Abstract: Certain aspects of the present disclosure provide techniques for measurement encoding and decoding using neural networks to compress and decompress measurement data. One example method generally includes: generating, via each of a plurality of neural network encoders operating on measurement data, a compressed measurement based on a respective portion of the measurement data, wherein each of the neural network encoders is based on the same neural network model; generating at least one message indicative of the measurement data based on the compressed measurements; and transmitting the at least one message.

Abstract: The aspects described herein may enable an apparatus to jointly encode two or more payloads using a single polar encoder device, while providing unequal error protection for the payloads. The apparatus causes a polar encoder to polar encode a first payload and a second payload to generate a polar encoded codeword. The polar encoder is configured to encode one or more bits of the first payload at a first reliability level and encode one or more bits of the second payload at a second reliability level, where the one or more bits of the first payload are associated with a first priority level and the one or more bits of the second payload are associated with a second priority level. The apparatus transmits the polar encoded codeword.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting wireless communication device may encode a data set using a single shot encoding operation and a temporal processing operation associated with at least one neural network to produce an encoded data set, wherein a dimensionality of a subset of inputs of a set of inputs to the temporal processing operation is greater than a dimensionality of the encoded data set. The transmitting wireless communication device may transmit the encoded data set to a receiving wireless communication device. Numerous other aspects are described.

Abstract: 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.

Abstract: Disclosed are techniques for determining round-trip time (RTT) of a user equipment (UE). In an aspect, each gNodeB in a plurality of gNodeB s measure signaling data related to an uplink RTT reference signal received from the UE and the downlink RTT reference signal transmitted by each gNodeB. The signaling data comprises one of a processing delay between a time of arrival (TOA) of the uplink RTT reference signal and a time of transmission (TOT) of the downlink RTT reference signal or a total RTT between the TOT of the downlink RTT reference signal and the TOA of the uplink RTT reference signal. The signaling data is sent to a single entity, other than the UE, e.g., another gNodeB or a location server, where signaling data relevant to the UE is aggregated. The aggregated signaling data may be sent to the UE to determine the RTT for the UE or used by the location server to determine the RTT for the UE.

Abstract: Disclosed are techniques for handling of radio frequency front-end group delays (GDs) for round trip time (RTT) estimation. In an aspect, a network entity determines information indicating a network total GD and a user equipment (UE) determines information indicating a UE total GD. The network entity transmits one or more RTT measurement (RTTM) signals to the UE, each including a RTTM waveform. The UE determines one or more one or more RTT response (RTTR) payloads for one or more RTTR signals, each including a RTTR waveform. The UE transmits the RTTR signal(s) to the network entity. For each RTTR signal, a transmission time of the RTTR waveform and/or the RTTR payload is/are determined based on the UE total GD. The network entity determines a RTT between the UE and the network entity based on the RTTM signal(s), the RTTR signal(s), and the information indicating the network total GD.
