A communication system is a communication system provided in a mobile body and including an acquirer configured to acquire a destination of the mobile body and a position of the mobile body, and a communicator configured to communicate with a communication device outside the mobile body using an antenna, in which the communicator is configured to set a reception sensitivity of the antenna when the position of the mobile body approaches to within a predetermined distance from the destination of the mobile body to be higher than a reception sensitivity of the antenna before the position of the mobile body approaches to within the predetermined distance.

Devices and methods for providing a retrievable record of the times of the actual aircraft movements such as the Gate Out time when the aircraft leaves the gate or parking position, the Wheels Off time when the aircraft takes off, the Wheels On time when the aircraft touches down during landing, and the Gate In time when the aircraft arrives at the gate or parking position (OOOI times). A mobile device for logging data onboard an aircraft comprises: a motion sensor; a clock; a non-transitory tangible computer-readable storage medium for storing motion data from the motion sensor and associated time data from the clock; and a data processing system configured to identify stored motion data representing respective acceleration/deceleration vectors of the mobile device motions that correspond to aircraft gate departure and arrival and aircraft takeoff and landing. The OOOI times are automatically logged in the non-transitory tangible computer-readable storage medium.

A system, computer software and method for collecting, in addition to position data, additional positioning data in a user terminal served by a communication network. The method includes initiating, by generating a message within the user terminal, collection of the positioning data, where the positioning data includes information based on which a physical location of the user terminal is determined; measuring, by the user terminal, at least one parameter related to the physical location of the user terminal in response to the message; producing, within the user terminal, measurement reports that include the at least one parameter; selecting, within the user terminal, one or more measurement reports that were generated in response to the message generated by the user terminal; reporting the selected one or more measurement reports to an interface within the user terminal; and transmitting, from the interface, the reported one or more measurement reports to an external server or to the communication network.

Systems, apparatus and methods may be configured to implement actively-controlled light emission from a robotic vehicle. A light emitter(s) of the robotic vehicle may be configurable to indicate a direction of travel of the robotic vehicle and/or display information (e.g., a greeting, a notice, a message, a graphic, passenger/customer/client content, vehicle livery, customized livery) using one or more colors of emitted light (e.g., orange for a first direction and purple for a second direction), one or more sequences of emitted light (e.g., a moving image/graphic), or positions of light emitter(s) on the robotic vehicle (e.g., symmetrically positioned light emitters). The robotic vehicle may not have a front or a back (e.g., a trunk/a hood) and may be configured to travel bi-directionally, in a first direction or a second direction (e.g., opposite the first direction), with the direction of travel being indicated by one or more of the light emitters.

A method, performed in a wireless device, for obtaining position information of user equipment, UE, in a wireless communication system is described. The method includes transmitting, to a network, an indication comprising beam information defining beams that are suitable to be used for transmitting Positioning Reference Signals, PRS, to the wireless device, receiving, from the network, control signaling comprising PRS scheduling information for upcoming transmission of the PRS in beams, performing measurements on the PRS based on the PRS scheduling information that was received, and providing the measurements to the network.

In an aspect, a communications node (e.g., TRP or UE) obtains (e.g., measures) timing group delays associated with different positioning procedures to determine time drift information, and reports the time drift information to an external entity for position estimation. In some designs, positioning procedures may comprise round trip time (RTT) measurements or uplink or downlink Difference Of Arrival (TDOA) measurements. In some designs, the time drift information indicates a drift rate function.

Methods, systems, and devices for wireless communications are described. A first base station may receive, from a plurality of user equipments (UEs), a plurality of uplink signals that include feedback information for the plurality of UEs. A first UE of the plurality of UEs may be associated with the first base station and a second UE of the plurality of UEs may be associated with a second base station. The first base station may modify a plurality of sets of beam weights for a plurality of downlink signals, where each modified set of beam weights corresponds to a respective downlink signal of the plurality of downlink signals. The first base station may transmit, to the first UE, a first downlink signal of the plurality of downlink signals using a first modified set of beam weights of the of the plurality of sets of beam weights.

A user equipment (UE) includes: a transceiver configured to receive positioning signals; a memory; and a processor, communicatively coupled to the transceiver and the memory, configured to: send, via the transceiver to a network entity, a capability indication that includes a first positioning-method indication indicating that the processor supports simultaneous processing of a first combination of positioning methods; and simultaneously process one or more first positioning signals in accordance with the first combination of positioning methods to determine first position information for the UE.

Methods and techniques are described for supporting location services for a user equipment (UE) in a Fifth Generation wireless network in which a base station, such as a gNB or ng-eNB, broadcasts a Positioning Reference Signal (PRS) in a plurality of different directions and at a plurality of different times. A PRS muting configuration is used in which PRS is muted using a time based and angle based pattern to prevent interference between beams transmitted by other base stations and/or to prevent interference between beams transmitted simultaneously by a single base station. The time based and angle based muting pattern, for example, may provide an indication for each direction in the plurality of different directions and for each time in the plurality of different times and as to whether the PRS is transmitted or muted by the base station.

A central location system provides an end-to-end high-accuracy positioning solution that provides navigation, geo-tagging, and general positioning data to receivers. The central location system does this by providing a cloud correction service and a robust positioning engine. For example, the central location system may provide single-frequency receivers with corrections for atmospheric delays and multipath throughout different geographic regions. The central location system computes corrections by leveraging location data from dual-frequency receivers. The central location system may also increase ionospheric delay coverage of portions of a geographic region. With increased ionospheric delay coverage, receivers can compute better location estimates. The central location system may also compute refined location estimates of single-frequency receivers and/or dual-frequency receivers for receivers with limited access to signals transmitted from satellites. The central location system may do this by estimating a receiver's location with respect to the location estimates of other receivers.
