US 11,689,249 B2 · Geographical localization of 5G/6G network users and base stations

Abstract

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.

Claims6

Dependent claims

Non-transitory computer-readable media in a base station of a wireless network comprising instructions that, when implemented, cause the base station to perform a method comprising:

a. determining a particular location corresponding to the base station or to an antenna of the base station;
and
b. broadcasting a synchronization signal block (“SSB”) message comprising system information about the wireless network, and further comprising an indication of the particular location as determined in the determining step, wherein the SSB message comprises:
i. a first orthogonal frequency-division multiplexing (“OFDM”) symbol comprising a primary synchronization signal (“PSS”) message, and further comprising the indication of the particular location;
ii. a second OFDM symbol comprising a portion of a physical broadcast channel (“PBCH”) message;
iii. a third OFDM symbol comprising a secondary synchronization signal (“SSS”) message;
and
iv. a fourth OFDM symbol comprising a further portion of the PBCH message.
