A method and a network node (300) for enabling wireless communication with a wireless device (302), wherein no more than a pre-determined maximum total transmit power is available for downlink transmission by the network node (300). When detecting that the wireless device (302) requires an extended transmission range (300B) which is larger than a nominal transmission range (300A), a boosted transmit power is determined and used for transmitting a first set of channels and/or signals to be used by the wireless device (302) to achieve the extended transmission range (300B). An attenuated transmit power is also determined and used for transmitting a second set of channels and/or signals not included in the first set of channels and/or signals, which provides a slightly reduced transmission range (300C) for the second set. The boosted transmit power is thus higher than a nominal transmit power, and the attenuated transmit power is lower than the nominal transmit power, so that the total transmit power used for transmitting said first and second sets does not exceed the pre-determined maximum total transmit power.

A control system includes a communications unit, an acquisition unit, and an output unit. The communications unit communicates with a transmitter that transmits a wireless signal. The acquisition unit acquires location information about a location of the transmitter based on the wireless signal that has been transmitted from the transmitter and received by the communications unit. The output unit has an instruction signal including adjustment information transmitted, in accordance with the location information acquired by the acquisition unit, from the communications unit to the transmitter. The adjustment information is used to vary at least one of a time interval at which the transmitter transmits the wireless signal or transmission power with which the transmitter transmits the wireless signal.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a wireless communication device, an acquisition signal that uses a lower transmit power level than a transmit power level of one or more other acquisition signals transmitted by the wireless communication device. The UE may transmit, to the wireless communication device, a response message to the acquisition signal that uses an initial access power configuration associated with the acquisition signal, the response message indicating at least one low power capability of the UE or location information of the UE. The UE may communicate, with the wireless communication device, in a connected communication mode using a low power configuration that is based at least in part on the at least one low power capability of the UE or the location information of the UE. Numerous other aspects are described.

5G and especially 6G are intended to accommodate high-speed mobile user devices and access points such as wireless devices on trains and airplanes, while retaining enhanced mobile broadband eMBB service. Therefore, new resource-efficient, low-complexity procedures are needed for measuring and correcting the Doppler frequency shift. To assist user devices, a base station or access point can periodically broadcast a current geographical location of the base station or access point in a localization message. In some embodiments, the geographical location data can be included in a periodically broadcast system information message, such as unused space of a SSB (synchronization signal block) message or an SIB1 (first system information block) message. User devices can then determine a vector toward the base station or access point relative to the user device location and velocity, and thereby calculate a Doppler correction without a frequency scan or other overhead, according to some embodiments.

Systems and methods are disclosed herein for uplink power control in a cellular communications network that are particularly well-suited for flying wireless devices (e.g., aerial User Equipments (UEs)). In some embodiments, a method performed by a wireless device for uplink power control comprises receiving, from a base station, reference altitude information comprising one or more height thresholds and detecting that a height of the wireless device is above a height threshold. The method further comprises triggering and sending a measurement report to the base station upon detecting that the height of the wireless device is above the height threshold, and receiving, from the base station, an indication to use a particular one of two or more fractional pathloss compensation factors for uplink power control. The two or more fractional pathloss compensation factors for uplink power control comprise one or more wireless device specific fractional pathloss compensation factors.

For Digital Subscriber Line (DSL), the whole system needs to deal with crosstalk of the neighboring pairs in the same bundle. A mechanism named Dynamic Spectrum Management (DSM) is proposed to optimize the overall performance of many subscriber lines, by means of lowering some unnecessary power spectrum density (PSD) on some lines and thus reducing their crosstalk to others. The decisions of the reduction (or power back-off, PBO) usually base on the loop distances between Central Office (CO) and the subscriber's premises. The shorter the distance, the lower the power. However, this does not consider the fact of each individual line's quality, i.e., its background noise or external interferences. The transceivers are able to collect such information. A negotiation process includes this information to adjust the power cutback, so that the cutback won't degrade the potential optimal performance of such lines.
