Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may transmit an indication to a base station that a total received power for the UE exceeds an overload threshold. In some cases, the indication may be an explicit request for a decrease in transmit power by a specific amount of reduction. The UE may transmit indications that the overload threshold is exceeded to multiple transmit/receive points. The indications may request specific transmit power reduction amounts that are specific to the TRPs, or may be generic indications that the overload threshold is exceeded, and the TRPs may coordinate to reduce their respective transmit powers to satisfy the overload threshold at the UE. The base station may allocate a first set of resources for near field UEs and a second set of resources for far field UEs.

Aspects of the subject disclosure may include, for example, obtaining a reference signal, power information regarding the reference signal, and maximum power threshold for the communication device from a base station over a communication network. Further embodiments can include measuring a power of reference signal obtained from the base station resulting in a measure power, and determining a path loss between the base station and the communication device based on the measured power. Additional embodiments can include adjusting the antenna array to generate a coarse power adjustment for the communication device based on the path loss and the maximum power threshold, and providing a transmission signal to the base station according to the coarse power adjustment over the communication network. Other embodiments are disclosed.

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a number of beam directions that satisfy a transmission power condition. The UE may select a beam direction for a random access signal by choosing one of the beam directions that satisfies additional criteria, such as transmitting a random access message at the next opportunity. The transmission power may be selected based on a target receive power and a path loss for the selected beam. In some cases, if the sum of the path loss for a beam direction and the target receive power exceeds a maximum transmission power by more than a predetermined amount, the random access signal will not be transmitted using that beam. In some cases, if a response to the random access is not received, a different beam direction may be selected, the transmission power may be increased, or both.

Methods and apparatuses for power control are disclosed. A method comprises: receiving a first signaling indicating one or multiple power values for a downlink reception from a node, each power value being associated with a spatial domain filter, and determining a power value for the downlink reception from the node.

Embodiments of the present invention provide a method and an apparatus for controlling transmit power of user equipment. The method includes: when total uplink transmit power of user equipment UE exceeds maximum allowed transmit power, calculating a first gain factor according to the maximum allowed transmit power; performing quantization processing on the first gain factor according to a gain factor of a first physical channel, to obtain a second gain factor, where the first physical channel includes a DPCCH2; reducing a gain factor of a second physical channel to the second gain factor, to reduce transmit power of the second physical channel, so that the total uplink transmit power of the UE does not exceed the maximum allowed transmit power, where the second physical channel includes an HS-DPCCH. This reduces a calculation error and improves control accuracy of transmit power.

A wireless communication device which can improve reception quality in a second other wireless communication device is disclosed, including a reception unit which receives a signal from a first other wireless communication device or a second other wireless communication device connected to the wireless communication device and the first other wireless communication device, a transmission power value setting unit which sets a transmission power value in a first subframe, in which the first other wireless communication device transmits a signal to the second other wireless communication device, to be higher than that in a second subframe in which the first other wireless communication device receives a signal from a third other wireless communication device connected to the first other wireless communication device, and a transmission power value switching control unit which performs switching in the first subframe to the transmission power value higher than that in the second subframe.

A user terminal that communicates using a plurality of CGs (Cell Groups) including a first CG and a second CG, includes a PHY layer processing section that controls transmission power of a PRACH (Physical Random Access Channel) in each CG; and a MAC layer processing section that controls retransmission of the PRACH. When total transmission power of PRACHs of the plurality of CGs that are transmitted in an overlapping manner exceeds allowable maximum transmission power, the PHY layer processing section controls so as to preferentially allocate transmission power to the PRACH of the first CG, and based on notification which is reported from the PHY layer processing section when total transmission power of PRACHs of the plurality of CGs that are transmitted in an overlapping manner exceeds allowable maximum transmission power, the MAC layer processing section controls power-ramping in retransmission of the PRACH of the second CG.

An electronic apparatus and a controlling method thereof are provided. The electronic apparatus includes: a first communication module configured to communicate in a first communication method, and a second communication module configured to communicate in a second communication method. The first communication module is further configured to change a transmission output level of the first communication module from a first transmission output level to a second transmission output level in response to the second communication module receiving data, and change the transmission output level from the second transmission output level to the first transmission output level in response to the second communication module completing the reception of the data.

The present disclosure relates to a method and user equipment, UE, in a wireless communication network of performing power scaling on uplink transmission to a receiving radio access node, RAN. In particular, the disclosure relates to a method and user equipment for power scaling on uplink transmissions on a multi-radio access bearer, multi-RAB, wherein a Dedicated Physical Data Channel, DPDCH, and enhanced Data Channels, E-DCHs are configured for uplink transmission from the UE to the receiving RAN. The method comprises determining a total UE transmit power exceeding a predetermined maximum power limit value. The total UE transmit power is reduced to the predetermined maximum power limit value by reducing one or more E-DPDCH gain factors by an equal scaling factor. When a predetermined minimum E-DPDCH gain factor, ‘smallest quantised βed,k value’, is reached for all E-DPDCH gain factors βed,k, and DTX is applied for all E-DPDCHs, the method comprises applying DTX on E-DPCCH.

The electronic device determines a back-off function defining at least one transmission power adjustment that is effective to adjust a predicted average energy emanating from an electronic device over the future time interval to satisfy a power condition. Power of the electronic device is adjusted according to the back-off function responsive to satisfaction of a proximity condition.
