Abstract: Certain aspects of the present disclosure provide techniques for feedback compression. Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes receiving, from a base station, a configuration to be used for compressing one or more measurements corresponding to at least one reference signal using an artificial intelligence (AI) encoder; receiving the at least one reference signal; and transmitting a codeword to the base station, the codeword being associated with a compression of the one or more measurements in accordance with the configuration.

Abstract: Techniques for position estimation using uplink (UL) and downlink (DL) signals via a fully or partially reciprocal wireless channel between a User Equipment (UE) and terrestrial transceiver can be enhanced by leveraging information obtained from UL or DL signals having the stronger Signal-to-Noise Ratio (SNR). This information can include the number of paths and/or complex sinusoids, and can be shared with the base station or location server to parameterize the model of the wireless channel. In some embodiments, the UE can further determine a quality metric for the model and send it to the location server or terrestrial transceiver.

Abstract: Methods and apparatuses for transmitting and detecting channel reservation preamble in a NR shared spectrum are described. An aspect may include determining whether a first reservation preamble of a first operator is received on a first time slot of multiple time slots of a downlink channel from a first network entity, and transmitting a second reservation preamble of the first operator on an uplink channel to the second network entity. Another aspect may include generating a first reservation preamble of a first operator based on at least one of a compressed representation in a signal space, a basis function of the signal space, or a CAZAC sequences; and transmitting, on a first timeslot of multiple time slots of a downlink channel, the first reservation preamble of the first operator to at least a UE. In another aspect, the SFN transmission of the first and second reservation preambles, and the low latency detection methods of the reservation preambles have been disclosed.

Abstract: Position determination of a user equipment (UE) is supported using channel measurements obtained for Wireless Access Points (WAPs), wherein the channel measurements are for Line of Sight (LOS) and Non-LOS (NLOS) signals. Based on WAP almanac information and the channel measurements, channel parameters indicative of positions of signal sources relative to a first position of a UE may be determined. Using the first position of the UE and an association of the signal sources with corresponding channel parameters, a second position of the UE may be determined. The position of the UE may be a probability density function. Additionally, position information for signal sources may be determined, such as a probability density function, as well as signal blockage probability and an antenna geometry and the WAP almanac information may be updated accordingly.

Abstract: Aspects of the disclosure relate to wireless communication systems configured to share a shared spectrum with one or more other systems (e.g., other operator networks utilizing the same radio access technology, and/or other networks utilizing different radio access technologies). Coexistence between the different systems on the shared spectrum may be provided by utilizing a technology-neutral signature waveform such as a signature sequence. A device or system may monitor a shared spectrum channel for the signature waveform, and when detected, may determine whether the shared spectrum is available for that system, or busy as occupied by another system. When the shared spectrum channel is idle, the device or system may reserve the channel by transmitting the signature waveform. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods and apparatuses for managing uplink scheduling for one or more user equipment served by a network entity in a wireless communications system are presented. For instance, an example method is presented that includes generating, by the network entity, an uplink bandwidth allocation map, the uplink bandwidth allocation map defining an uplink bandwidth allocation for at least one of the one or more user equipment for at least one of a plurality of uplink transmission window lengths. In addition, the example method includes transmitting the uplink bandwidth allocation map to at least one of the one or more user equipment.

Abstract: Wireless communications systems and methods related to dynamic medium sharing are provided. A first wireless communication device communicates with a second wireless communication device, a reservation request (RRQ) for a transmission opportunity (TXOP) in a shared spectrum. The shared spectrum is shared by a plurality of network operating entities. The first wireless communication device and the second wireless communication device are associated with a first network operating entity of the plurality of network operating entities. The RRQ indicates a first traffic priority of data to be communicated. The first wireless communication device communicates with the second wireless communication device, the data of the first traffic priority during the TXOP.

Abstract: Wireless communications systems and methods related to reclaiming of resources in a shared frequency spectrum shared by multiple operators are provided. A first wireless communication device associated with a first operator of a plurality of operators identifies a transmission opportunity in a shared frequency spectrum shared by the plurality of operators, wherein the first operator has priority among the plurality of operators for accessing the shared frequency spectrum in the transmission opportunity. The first wireless communication device communicates with a second wireless communication device associated with the first operator, in the transmission opportunity without a prior reservation of the transmission opportunity.
