Systems and methods for dynamic cell breathing for power saving are disclosed. In some embodiments, a method of operation of a radio access node includes determining a target transmit power level from multiple predetermined transmit power levels for the radio access node. The method also includes determining that the current transmit power level should be adjusted to reach the target transmit power level and, in response, adjusting a transmit power level of the radio access node from the current transmit power level to the target transmit power level via multiple transmit power level adjustments. Adjusting the power level of the radio access node via more than one transmit power level adjustment makes it possible to avoid some of the issues with the sleep mode proposal, according to some embodiments.

A device and/or method for dynamically adjusting a CCA threshold in an addressable unit that is suitable for communication in a wireless network, the method performed in the addressable unit and comprising autonomously increasing the CCA threshold with successful data transmissions and/or autonomously decreasing the CCA threshold with unsuccessful data transmissions.

Methods and systems for preventing or delaying handovers to target access nodes that are not configured to provide uplink split mode, include determining that an uplink usage requirement or a power headroom of a wireless device meets a threshold, and preventing handovers of the wireless device to access nodes that are not capable of utilizing uplink split mode. Access nodes capable of utilizing uplink split mode are configured to receive uplink data via at least two different radio access technologies simultaneously, including 4G LTE and 5G NR.

A sending method for a Scheduling Request (SR) under carrier aggregation is provided. A User Equipment (UE) receives, through a Radio Resource Control (RRC) message, and stores Physical Uplink Control Channel (PUCCH) configuration information and SR configuration information of a plurality of serving cells, and, when determining that an SR needs to be sent, the UE selects, according to the SR configuration information, a serving cell from the plurality of serving cells corresponding to the stored PUCCH configuration information to send the SR. A sending device for a scheduling request under carrier aggregation, a terminal and a storage medium are also provided.

A method for providing a Power Headroom Report (PHR) is provided. In the method, a User Equipment (UE) receives configuration information of serving cells; a corresponding relationship between a first region of a PHR and the serving cells is determined according to the configuration information of the serving cells, and the first region is used for indicating whether power headroom information of one or more serving cells is contained in the PHR. Another method for providing the PHR, two devices for providing the PHR, and a computer storage medium are also provided.

A method is described of evaluating the energy consumption of a service unit rolled out, or intended for being rolled out, on a given infrastructure of a communications network. The method includes determining the energy consumption W_no measured on the infrastructure in the absence of the service unit, determining the energy consumption W_yes measured on the infrastructure in the presence of the service unit, and obtaining the energy consumption induced by rolling out the service unit by calculating the difference (W_yes−W_no). The disclosed technology is applicable to 5G networks.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that schedules an uplink communication in an uplink frequency band. The UE may transmit, at an uplink frequency within the uplink frequency band, the uplink communication with a power that varies over the uplink frequency band based at least in part on a location of the uplink frequency relative to a downlink frequency band associated with the UE. Numerous other aspects are provided.

Disclosed are techniques for wireless communication. In an aspect, BS transmits first and second configurations for first and second BWPs to UE. The first BWP is set as an active BWP based on the first configuration. BS transmits TCP command(s) that set an active power control adjustment state. BS transitions the active BWP from the first BWP to the second BWP based on the second configuration. The active power control adjustment state is maintained after the active BWP transition (e.g., not reset to some default state).
