Certain aspects of the present disclosure provide techniques for assigning or adjusting a transmit-power control mode, or parameters of a transmit-power at a user equipment used in sidelink communications. In some examples, the disclosure describes determining a user equipment (UE) is connected to the BS, and configuring the UE to use a first transmit-power control mode for determining a transmit-power used for transmitting wireless data over a sidelink based on the BS being positioned indoors.

Systems and methods for an in-vehicle base station are described. In one embodiment, a mobile base station is disclosed comprising a first access radio for providing an access network inside and outside a vehicle; a second backhaul radio for providing a backhaul connection to a macro cell; and a global positioning system (GPS) module for determining a location of the mobile base station, and for transmitting the location of the mobile base station to a core network, wherein a transmit power of the first access radio is configured to increase or decrease based on a speed of the vehicle.

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.

An example electronic device includes a wireless communication component and a controller. The controller is to set an output power of the wireless communication component based on: whether a first external object is in proximity to a first side of the electronic device; whether the electronic device is stationary; and whether a second external object is in proximity to a second side of the electronic device, where the second side is opposite to the first side.

This disclosure relates to a method for reducing power consumption of a first device for use in a wireless communication system. The first device receives a signal within a first reference sub-frame of a radio channel. The device determines whether to use the signal for obtaining channel state information to be reported to a second device within a reporting sub-frame, or whether to receive and use a second signal within a second reference sub-frame of the radio channel for obtaining channel state information to be reported to the second device within said predetermined later sub-frame. Based on this determination, the first device reports channel state information obtained based on the signal received within said first reference sub-frame or said second signal within said second reference sub-frame to the second device within said reporting sub-frame.

In an aspect, a user equipment (UE) determines a resource configuration and a transmit power for a physical random access channel (PRACH) preamble sequence and/or a configuration and a transmit power for a physical uplink shared channel (PUSCH) resource unit (PRU) based on positioning information of the UE relative to the base station, the speed of the UE relative to the base station, and/or a radio resource control (RRC) state of the UE, transmits, to the base station, a message comprising the PRACH preamble sequence on a PRACH occasion and a payload on a PRU occasion based on the determined resource configuration and transmit power for the PRACH preamble sequence and/or the determined resource configuration and transmit power for the PRU, and receives, from the base station, a second message comprising information on a physical downlink control channel (PDCCH) and a payload on a physical downlink shared channel (PDSCH).

Embodiments of the present disclosure provide methods and devices for communication by a terminal. The method can include: sending a first message to a server, the first message comprising command information, the command information comprising first state information of the terminal, and the first state information comprising at least one of mobile attribute information, moving state information, mobile state start information, stationary state start information, or moving direction state information, wherein the mobile attribute information is used to indicate that the terminal is a mobile terminal, the moving state information is used to indicate that the terminal is in a mobile state, the mobile state start information is used to indicate a transition of the terminal from a stationary state to a mobile state, the stationary state start information is used to indicate a transition of the terminal from a mobile state to a stationary state, and the moving direction information is used to indicate direction information of movement of the terminal; and receiving a second message sent by the server, wherein the second message is used to confirm the at least one of first state information in the command information.

Aspects relate to mechanisms for wireless communication devices to environmental sensing with the assistance of a network. A UE transmits an increase transmission power request message to a base station. The UE receives an increase transmission power acceptance message from the base station in response to transmitting the increase transmission power request message. The UE transmits a transmission using an increased transmission power for reflection by at least one object based on the increase transmission power acceptance message. The UE receives a reflection of the transmission reflected off the at least one object. The UE determines at least one parameter associated with the object based on the reflection of the transmission reflected off the at least one object.

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.
