  • Publication number: 20240273829
    Abstract: Extended reality (XR) management systems and techniques are described. In some examples, an XR management system receives sensor data from an XR interface device having at least one sensor. The XR management system generates, based on the receipt of the sensor data from the XR interface device, processing instructions for an XR processing device to process the sensor data to generate XR content. The XR management system sends the sensor data and the processing instructions to the XR processing device. The XR management system receives the XR content from the XR processing device. The XR management system generates layer content. The XR management system sends the XR content and the layer content to the XR interface device to cause the XR interface device to output the XR content and the layer content in a layered arrangement.

  • Publication number: 20240276404
    Abstract: Non-terrestrial networks (NTNs) may establish uplink (UL) and downlink (DL) radio frame timing structures to efficiently account for propagation delay and propagation delay variation associated with communications in the NTN. NTNs may manage (synchronize) radio frame timing structures of base stations (e.g., satellites) and user equipment (UEs) in the NTN. Further, UEs may determine timing advance (TA) values to be applied to UL transmissions based on their respective scheduling offset (e.g., offset in UL and DL radio frame timing structures), as well as based on propagation delay or round trip time (RTT). As such, served UEs may determine UL timing such that UL transmissions from the UEs to a satellite arrives at the satellite in a time synchronized manner. In other cases, a satellite may determine UL timing, based on reception timing, such that various UEs in the NTN may implement uniform UL and DL radio frame timing structures.

  • Publication number: 20240267808
    Abstract: Methods, systems, and devices for wireless communications are described. A UE operating in an NTN may receive an indication of coverage information for a first cell associated with the NTN. The coverage information may indicate a coverage area supported by the first cell for wireless communications. The UE may transmit, based on location information of the UE and the coverage information, a message indicating a timing information associated with a measurement-based handover for the UE from the first cell to a second cell associated with the non-terrestrial network. For example, the message may include a recommendation for the UE to perform a non-measurement-based handover or an indication that the UE cannot complete the measurement-based handover before leaving the coverage area of the first cell.

  • Publication number: 20240267865
    Abstract: A user equipment (UE) receives one or more timing advance commands from a non-terrestrial network (NTN). The UE resets, after a GNSS fix, a cumulative timing advance value based on the one or more timing advance commands from the NTN and transmits an uplink transmission with a timing advance based on a self-estimated delay and the cumulative timing advance value. The UE may adjust a self-estimated delay based on at least one GNSS fix. The UE may transmit an uplink transmission with a timing advance based on the adjusted self-estimated delay and a cumulative timing advance value based on the one or more timing advance commands from the NTN.

  • Publication number: 20240243821
    Abstract: Aspects are provided which resolve neighbor beam-wise interference. A UE obtains a plurality of reference signals from each of at least one neighbor base station, where each of the reference signals is obtained in a different beam, and each of the neighbor base station(s) is in a different neighbor cell. The UE then measures a signal strength associated with each of the reference signals, and the UE indicates one or more of the reference signals to a serving base station in a serving cell, where the signal strength of each of the reference signal(s) indicated to the serving base station exceeds a threshold RSRP. After the serving base station obtains the indication from the UE, the serving base station coordinates with the neighbor base station(s) to modify one or more transmission parameters in response to the indication.

  • Patent number: 12035263
    Abstract: Methods, systems, and devices for wireless communications are described in which UEs may communicate with satellites or base stations, or both in a non-terrestrial network. Due to large distances between transmitting devices and receiving devices in a non-terrestrial network, the UE may account for propagation delay and frequency shift of communications with a satellite based on location information of the satellite. The UE may receive first satellite location information from a base station or a satellite, via a broadcast message. The UE may receive second satellite location information from the wireless network node via a unicast message, where both the first satellite location information and the second satellite location information relate to a same satellite. The UE may transmit an uplink communication via the satellite based on at least one of the first satellite location information or the second satellite location information.

The indication may be based on one or more types of the one or more uplink wireless communications. The UE may determine a duration of time for which an uplink pre-compensation is to be applied to the one or more uplink wireless communications. The duration of time may be based on one or more parameters of the uplink communications configuration. The UE may output the one or more uplink wireless communications within the duration of time with the uplink pre-compensation applied.

  • Publication number: 20240187899
    Abstract: Aspects are provided which improve RLM by allowing a UE to apply a longer monitoring window for out-of-sync determinations before the UE triggers an RLM timer for in-sync determinations. The UE first obtains a reference signal from a base station. The UE then determines multiple groups of consecutive out-of-sync indications in response to the reference signal. For example, the UE may perform looped out-of-sync monitoring, multi-cell or carrier monitoring, or a combination of such monitoring to determine the multiple groups of out-of-sync indications. Afterwards, the UE triggers the RLM timer in response to determining the multiple groups of consecutive out-of-sync indications. As a result, the UE may perform additional out-of-sync monitoring during RLM before proceeding with in-sync monitoring, thus allowing the UE to account for rapid BLER changes (ping-pong effects) that may occur in HAPS systems due to tropospheric turbulence and enabling more accurate RLM determinations and minimal RLF detections.
