Aspects of the disclosure relate to downlink (DL) transmissions using various powers and assigning frequency resources based on the powers. An example base station may transmit, to a first user equipment (UE), an indication of a first transmit (Tx) power for one or more first DL transmissions to a first group of a plurality of groups. The first group may include the first UE. The first Tx power may have a first power level different from a second power level of a second Tx power for one or more second DL transmissions to a second group of the plurality of groups. Then, the base station may transmit, to the first UE, a first DL transmission of the one or more first DL transmissions using the first Tx power. Other aspects, embodiments, and features are also claimed and described.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may determine, based at least in part on a first model, an estimated position of the first wireless communication device. The first wireless communication device may determine, based at least in part on a second model, an estimated direction for transmission of a packet to a second wireless communication device. The first wireless communication device may determine, based at least in part on a third model, an estimated transmit power for transmission of the packet. The first wireless communication device may determine, using a neural network, a narrow beam based at least in part on the estimated position, the estimated direction, and the estimated transmit power. The first wireless communication device may transmit the packet on the narrow beam to the second wireless communication device. Numerous other aspects are provided.

In a wireless communication system in which a plurality of base stations each forming a directional beam in one direction are disposed along a predetermined path, each base station estimates a distance from installed in a mobile body moving along the path if the TE enters a cell area of the corresponding base station; and controls the transmission power using a distance from the estimated TE so that a difference between received signal strength of the corresponding base station and the received signal strength of neighboring base stations measured by the TE in a cell boundary area between the base stations does not exceed a predetermined threshold value.

The present invention relates to a method for controlling uplink transmission power and to a wireless device using same in a wireless communication system. The wireless device receives determines uplink transmission power in consideration of the overlap period between subframes between a first serving cell belonging to a first timing advance (TA) group and a second serving cell belonging to the second TA group, and transmits an uplink channel on the basis of the uplink transmission power.

Provided are a method for performing sidelink transmission by a transmission terminal in a wireless communication system, and a device supporting same. The method can comprise the steps of: adjusting a parameter associated with sidelink transmission on the basis of the height of an antenna of a transmission terminal; and performing sidelink transmission for a reception terminal on the basis of the adjusted parameter.

There is provided a communication device comprising: a control unit configured to control ranging with a wireless signal in conformity with a regulated communication standard, wherein the control unit controls output intensity of a data transmission signal that has a payload based on reception sensitivity for a plurality of ranging signals transmitted to and received from other communication devices.

A user equipment (UE), or other network component can operate to generate new radio (NR) communications in millimeter wave (mmW) frequencies. Body proximity sensing (BPS) operations can be performed to determine whether a maximum permissible exposure (MPE) event is triggered. A safe transmit power level associated with the one or more bands can then be used to provide the NR communications. Additionally, determinations of whether various conditions are satisfied to suspend the BPS operations for a period can be evaluated and implemented. The BPS can be configured such that a BPS period of the BPS operations are aligned with a discontinuous reception (DRX) cycle at a beginning of a DRX on-duration of a DRX cycle, wherein the one or more conditions comprise a DRX idle time or state.

The present disclosure is directed to techniques to facilitate power boosting for wireless communication devices (e.g., user equipment). The user equipment may be subject to specifications (e.g., the 3GPP specification) that require maximum power reduction (MPR) depending on the resource block allocation region in which the user equipment is operating. However, certain regions defined by the 3GPP specification may not facilitate transmission power boost as applied to shaped (e.g., modulated) transmissions. The techniques disclosed herein include defining the regions such that the MPR restrictions applied to the user equipment are reduced or minimized for allocations that enable power boosting. The regions may be defined using parameters based on a maximum number of resource blocks specified for a certain channel bandwidth, the amount of allocated resource blocks, and the resource block at which the allocation begins.
