In 5G/6G wireless networks, user devices and base stations may adjust their transmission power according to the distance to the recipient, and thereby provide sufficient reception without wasting energy or generating interference. User devices can determine their own location by GPS, for example, and transmit that data to the base station so that the base station can adjust its downlink power accordingly. Likewise. base stations can transmit their location coordinates to user devices in, for example, a system information message. Sidelink, or V2V and V2X, messages can likewise be power-adjusted after user devices exchange their location coordinates. Mobile user devices can also indicate their speed and direction of travel, so that the base station or other user devices can calculate the changing distance and compensate power accordingly. The method may enhance reliability by providing that messages arrive at the recipient with sufficient amplitude for reception, and may provide low latency by avoiding the time-consuming power scan, while avoiding delays for retransmissions and the like.

In an embodiment, a wireless node (e.g., UE or BS) receives from a network component (e.g., BS or core network component) a request for a positioning estimate of a UE associated with a specified time. The wireless node performs positioning measurements at a plurality of times, and determines (e.g., via interpolation or extrapolation) the positioning estimate associated with the specified time based on the positioning measurements. The wireless node transmits, to the network component, a report comprising the determined positioning estimate.

Aspects of the subject disclosure may include, for example, identifying positioning information associated with a wireless communication device, determining a current location of the wireless communication device based on the positioning information, detecting a location change based on the current location of the wireless communication device, and responsive to the detection of the location change, sending a location change notification to a location management entity. Other embodiments are disclosed.

A system and method for locating a mobile device relative to a vehicle using mechanical waves and modulation techniques. A high frequency carrier wave that is generally inaudible to humans is modulated with a low frequency baseband signal that provides for accurate localization in order to generate a modulated signal. The modulated signal is a mechanical or pressure wave, as opposed to an electromagnetic (EM) wave, that is transmitted by one or more speaker(s) and is received by one or more microphone(s). In one example, the modulated signal is transmitted from a speaker on the mobile device (e.g., a smart phone) to a number of microphones mounted on the vehicle at specific distances apart, so as to establish multiple localization paths whose differences in phase can be used to determine the location of the mobile device, relative to the vehicle.

A method for location-dependent billing for a services that are available to a mobile terminal, a local communication connection is set up to a fixably installed external location tag with a corresponding wireless interface between the fixably installed tag and the mobile terminal, the method including the steps of accessing the external location tag and transmitting a billing rate code from the external location tag to the mobile terminal, forwarding the billing rate code from the mobile terminal to a central unit of a mobile communication network, in which the mobile terminal is logged, determining a geographic location identification of the external location tag by evaluation of the billing rate code at the central unit, and selecting a billing rate for billing for the service available to the user based on the billing rate code at the central unit.

An external client requests the location of a UE using control plane signaling. The UE sends downlink location measurements, such as Reference Signal Time Differences, for a plurality of base stations (BSs) to a serving BS at a layer 1 or layer 2 protocol level and at first periodic intervals. The UE and the plurality of BSs send additional location measurements, such as receive time-transmission time differences, to the serving BS at second periodic intervals, which are longer than the first periodic intervals. The serving BS uses the additional location measurements and downlink location measurements to determine timing information, such as Real Time Differences, for the plurality of BSs. The serving BS determines the location of the UE using the downlink location measurements and the timing information at the first periodic intervals and sends the location to the external client using user plane signaling to reduce delay.

Methods, apparatus, and processor-readable storage media for determining a set of access points in response to a geo-location request are provided herein. An example computer-implemented method includes determining, based on geo-location information comprising a set of at least two coordinates attributed to at least one device, geo-location information attributed to a set of multiple access points; identifying two or more access point subs-sets from the set of access points, wherein each of the access point sub-sets comprises one or more of the access points; comparing geo-location information attributed to additional devices to the access points within each of the sub-sets; and outputting, to the at least one device as a response to a request for geo-location information comprising a set of at least two coordinates and based on said comparing, information pertaining to at least one of the sub-sets and the geo-location information attributed to the at least one device.

In 5G and 6G, efficient communication relies on narrow communication beams directed between the transmitter and the intended recipient. However, the optimal beam direction changes whenever the user moves, as in traffic. The user device can inform the base station of the user's initial location, speed, and direction of travel, so the base station can calculate the appropriate beam direction versus time. However, if the mobile user device changes in speed or direction, this may result in an erroneous calculation by the base station. The directional error may be insignificant if the directional error is much less than the beam width. The mobile user device can calculate the directional error based on the change in speed or direction, and when the directional error becomes comparable to the beam width of the base station, the user can transmit a message to the base station indicating the new location, speed, and direction.

The transmission power level is an important parameter in 5G/6G networking because it affects the failure rate if too low, background interference if too high, and battery life of user devices if retransmissions are required, among many other aspects of communications. Disclosed is an AI (artificial intelligence) model to recommend a transmission power level, based on inputs including: current network parameters such as the current throughput or message failure rate or average delay per message; parameters of the planned parameters such as the length and priority of the planned message; and environmental parameters such as the current noise or background interference level. In addition, the AI model adjusts for the distance between the transmitter and receiver, plus any known obscurations, among other inputs. The AI model then provides a recommended power setting for each message, adjusted to provide reliable reception but without wasting excess power.

Disclosed are systems and methods for entities in a 5G or 6G wireless network to indicate their geographical location to other entities. A base station can inform the user devices of its antenna location so that the users can direct beams toward the antenna. Mobile users can update their location information to the base station so that the base station can direct beams toward the mobile users in real-time. For example, the base station can embed the latitude and longitude of the base station antenna in a system information message, such as an unallocated portion of the SSB (synchronization signal block) which is periodically broadcast, and the users can transmit location-update messages to the base station using disclosed formats. By directing transmission beams and reception beams toward each other, base stations and users can obtain substantially improved reception with reduced background generation and reduced energy consumption.
