Transmission power adjustment for a transmission of sounding reference signals

A wireless device receives, from a base station, parameters of a first sounding reference signal (SRS); and a second SRS. A downlink control information triggering transmission of the first SRS is received. A control element activating transmission of the second SRS is received. A transmission power of the second SRS is adjusted based on: the first SRS having higher priority than the second SRS; the first SRS overlapping in time with the second SRS; and a total transmission power exceeding a total allowable power value. The first SRS is transmitted. The second SRS with the adjusted transmission power is transmitted.

Location-based system information and doppler correction in 5G/6G
11611375 · 2023-03-21 · ·

A base station of a 5G/6G network can include its location coordinates in the SSB system information message which is broadcast on a standard frequency periodically. A mobile user device can receive the SSB and thereby determine the base station location. Thereafter, the user device can measure its own location, speed, and direction of travel, and thereby calculate a Doppler frequency correction before transmitting a message to the base station, thus causing the base station to receive the message at the expected standard frequency. In addition, the user device can calculate, based on the location of the base station relative to the direction of travel of the mobile user device, a particular frequency at which downlink messages from the base station will be received. In addition, the user device can pre-emptively adjust its transmission frequency when changing speed or direction, thereby avoiding wasteful frequency-correction messages from the base station.

Systems and methods for dynamic per-beam adjustment of output power in a wireless network

A system described herein may provide a technique for determining a maximum and/or target output power on a per-beam and/or per-direction basis for a base station of a radio access network (“RAN”) that implements multiple beams for which output power is dynamically adjustable. The maximum and/or target output power for a given beam (or set of beams) for a given time period may be determined based on historical output power information associated with the beam over one or more previous time periods. The maximum and/or target output power may be based on a predicted received signal power within a coverage area of the base station, based on varying levels of output power.

Determining power optimization for multiple radios based on historical power usage in advanced networks

Facilitating real-time power optimization in advanced networks (e.g., 5G, 6G, and beyond) is provided herein. Operations of a method can include determining, by a system comprising a memory and a processor, a power distribution setting for a user equipment that includes multiple radios based on a historical radio power usage, a historical performance result, a current location, and an application currently executing on the user equipment. The method also can include implementing, by the system, the power distribution setting across the multiple radios of the user equipment. The first radio of the multiple radios can be a first radio type and a second radio of the multiple radios can be a second radio type, different from the first radio type.

Power control for random access

Systems, apparatuses, and methods are described for wireless communications. Random access procedures may include various steps, such as 4-steps or 2-steps. One or more indicators such as, for example, transmission power requirements, may be used to indicate which random access procedure to utilize.

ELECTRONIC TILT COVERAGE

A booming cell start distance and recommended electronic tilt is identified by retrieving a list of cells served by a first base station. A plurality of grids is generated from the first base station to a predetermined threshold distance. A plurality of selected grids is identified between an acceptable coverage limit and a threshold distance. An evaluation is made regarding whether the first base station is not the dominant cell in each of the selected grids based. The number of grids where the first base station is not the dominant cell site is determined based on a dominant carrier threshold. A column of grids where the first base station is no longer the dominant cell site is determined based on the dominant carrier threshold. A bad booming distance of the cell is determined based on the distance from the first base station and the determined column of grids.

Power management by powering off unnecessary radios automatically

A system and method are provided for automatically shutting off or reducing power to certain radios in a client device based on collected wireless network quality parameters. The wireless network quality parameters are collected from wireless networks by various client devices in communication with the wireless networks. The client devices report the wireless network quality parameters to a server. The server collects wireless network quality parameters from a plurality of client devices and analyses the wireless network quality parameters from the plurality of client devices to determine a network quality for the particular wireless networks. The network quality is stored in a network quality database maintained by the server. When it is determined that a device is in an area of weak signal coverage, power to its radio is automatically reduced or shut off until the device leaves the area.

SYSTEMS AND METHODS FOR DYNAMICALLY ALLOCATING WIRELESS SERVICE RESOURCES CONSONANT WITH SERVICE DEMAND DENSITY
20170353960 · 2017-12-07 ·

Wireless service is provided to a service area using limited resources dynamically reallocated to maximize capacity in high demand regions. An antenna array transmits a plurality of downlink beams, each covering a respective region of a service area. An antenna management logic identifies a high demand region serviced by downlink beams transmitted from a first set of antennas at a first power level and a low demand region serviced by downlink beams transmitted from a second set of antennas at a second power level. The antenna management logic reconfigures the antenna array to provide the wireless service to the high demand region at a power level higher than the first power level, and to provide the wireless service to the low demand region at a power level lower than the second power level, such that the antenna array does not exceed a maximum power level available from a power supply.

Transmission Power Compensation by Attenuation Mapping in 5G and 6G
20220376742 · 2022-11-24 ·

For improved messaging reliability in 5G and 6G, mobile users and their base stations can adjust their transmission power according to the current location of the mobile user. Each entity can maintain a map of known attenuation values, including “dead zones”, and can adjust their transmission power and/or reception gain to compensate. Instead of constantly exchanging location-update messages, the users can indicate their speed and direction, and the base station (or other users) can extrapolate the location versus time to determine a future location, and thereby determine the attenuation factor at the new position. In addition, the base station can use a map to follow the mobile user device's progress, and can thereby update the attenuation factor in real-time. If the mobile user makes a change, it can inform the base station at that time, or during initial access. Result: improved reliability, lower energy consumption, improved traffic safety.

PROGRAM FOR ADJUSTING CHANNEL INTERFERENCE BETWEEN ACCESS POINTS IN A WIRELESS NETWORK

The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.
