A wireless communication node sets a downlink target value of a received power of a downlink from an upper node based on a received power of an uplink from a lower node, and transmits, to the upper node, power control information based on the downlink target value.

An apparatus for use by a communication network control element or function configured to conduct a radio resource management, the apparatus being configured to cause the apparatus at least: to acquire input parameters; to process the input parameters by using a first-stage procedure for maximizing a weighted sum-rate for a fixed subcarrier allocation for all subcarriers, and a second-stage procedure for determining a power allocation for a single subcarrier under consideration of specified multiplexing and interference cancellation constraints wherein a processing result output from the first-stage procedure is input into the second-stage procedure, and a processing result output from the second-stage procedure is returned to the first-stage procedure; and to output, on the basis of results of the processing in the first-stage procedure and the second-stage procedure, a power setting for at least one subcarrier.

Aspects of the subject disclosure may include, for example, obtaining channel cross correlation data relating to multiple user equipment (UEs) being served in a cell, wherein the channel cross correlation data comprises a correlation coefficient associated with a first UE of the multiple UEs and a second UE of the multiple UEs, identifying that the first UE is experiencing decreasing throughput, responsive to the identifying that the first UE is experiencing decreasing throughput, determining whether the correlation coefficient associated with the first UE and the second UE satisfies a correlation threshold, and, based on a first determination that the correlation coefficient does not satisfy the correlation threshold, adjusting a downlink (DL) transmit power allocation for transmissions directed to the first UE. Other embodiments are disclosed.

An access point (AP) communicates to one or more stations (STAs) information indicating a set of channels and/or resource units (RUs), corresponding to a wideband basis service set (BSS) for an authorized unlicensed radio local area network (RLAN) using 6 GHz spectrum, which are subject to a lower power spectral density (PSD) level than other portions of the BSS frequency range or are not to be used for transmission. In some, but not necessarily all, embodiments, the AP and the STAs do not encode data on the identified channels or RUs, but do encode data on other channels and/or other RUs, which are not subject to the lower PSD constraint.

This disclosure provides methods, devices, and systems supporting power control parameter configuration for configured grants (CGs). In some implementations, a user equipment (UE) may receive control signaling configuring multiple sounding reference signal (SRS) resource sets and multiple sets of power control parameters for CG uplink transmission. The UE may receive downlink control information (DCI) scheduling a retransmission and indicating which set of power control parameters the UE is to use for the CG uplink retransmission. In some other implementations, the control signaling may configure multiple SRS resources sets but a single set of power control parameters. The UE may receive DCI activating the CG configuration or scheduling a retransmission, the DCI indicating a second set of power control parameters not configured by the control signaling. The UE may automatically use the power control parameters configured by the control signaling or may determine a second set based on the DCI.

Channel state information reference signal transmission can be used to estimate channel state information. Although resources needed for channel state information reference signals can be small, when multiple bandwidths are deployed within the same orthogonal frequency division multiplexing bandwidth, estimating the channel state information can comprise a channel state information reference signal resource grid for every bandwidth. Therefore, time-frequency resources for channel state information reference signals can be high and occupy a lot of bandwidth, thereby reducing the number of resources for data transmission. Therefore, a non-orthogonal design for channel state information reference signals for a 5G air interface can mitigate bandwidth loss in a 5G network.

This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. For example, a communication system may include a repeater that relays communications between communication devices. The repeater determines a downlink gain value to use for one or more downlink initial access messages received at the repeater. The repeater determines an uplink gain value to use for one or more downlink initial access messages received at the repeater. The uplink gain value is based on the downlink gain value and a noise level related to a channel between the communication device and the repeater. The repeater receives a downlink initial access message, and applies the downlink gain value to the downlink initial access message. The repeater receives an uplink initial access message, and applies the uplink gain value to the uplink initial access message.

An electronic device comprising circuitry that controls transmitting signals through a first communication link toward a base station or a second communication link toward a mobile station. The second communication link uses an uplink resource of the first communication link. The circuity determines transmission power for the second communication link based on a first parameter and a second parameter. The first parameter indicates a signal level, a power level, or a noise level in the first communication link. The second parameter corresponds to path loss information for the first communication link.

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines an interference type between a time division duplex (TDD) configuration subframe of a serving cell and a corresponding TDD configuration subframe of a neighboring cell, and sets a transmit power for an apparatus in the serving cell based on the interference type. The apparatus in the serving cell may be a user equipment (UE), in which case the apparatus applies a set of uplink (UL) open loop power control parameters for the UE. The apparatus in the serving cell may be a base station (eNB), in which case a DL transmit power is set for the eNB. Depending on the interference type, the DL transmit power may be a fixed, full power DL transmission or an adjusted DL transmission.

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.
