Apparatuses and methods for transmission power control are disclosed. A given transmission resource and a first transmission power are determined (202, 204) for transmission. Prior to transmitting on the given transmission resource it is determined (206) whether the resource is occupied or unoccupied. Upon detecting that the resource is occupied, a second, reduced transmission power is determined (210) such that a transmission using the second, reduced transmission power would not render the resource as occupied. The determination of the second transmission power is based at least partially on a predetermined maximum transmission power reduction value. Transmission (212) is done utilising the given transmission resource using the second transmission power according to the determination.

A mechanism for distributing traffic between a macro access node and a micro access node in a heterogeneous network is described. The method, performed by a network node controller, comprises obtaining information of current traffic load in the heterogeneous network. The method further comprises distributing the traffic between the macro access node and the micro access node by adjusting cell shaping beams of the macro access node as a function of the current traffic load.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive one or more reference signals associated with a sensing signal, and transmit a sensing interference report that indicates one or more parameters for reducing interference for the sensing signal. Numerous other aspects are provided.

Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE). The method generally includes receiving a downlink control information (DCI) with at least one block configured to trigger aperiodic sounding reference signal (SRS) transmission from the UE on at least one SRS resource set, determining a transmit power control (TPC) command to apply to the A-SRS if the DCI lacks a transmit power control (TPC) command for the at least one SRS set, and transmitting the A-SRS in accordance with the DCI and the determined TPC command.

Reduced transmission power time intervals for wireless communications are described. A node may transmit a time interval allocation bitmap indicating a configuration of reduced transmission power time intervals. The configuration of reduced transmission power time intervals may change based on traffic load at the node.

A primary wireless access node wirelessly transmits reference signals at an initial reference signal power level. The primary wireless access node exchanges data with User Equipment (UEs) and exchanges the data with other network elements. The primary wireless access node exchanges signaling with secondary wireless access nodes. The secondary wireless access nodes exchange data between the UEs and the network elements responsive to the signaling. The primary wireless access node determines the amount of the secondary nodes and determines a new reference signal power level based on the amount of the secondary nodes. The primary wireless access node wirelessly transmits subsequent reference signals at the new reference power level.

Certain aspects of the present disclosure provide techniques for interference control for uplink transmission, for example, using multiple transmission configurations (e.g., antennas, beams, and/or antenna panels). A method that may be performed by a user equipment (UE) includes determining a transmit power for one or more uplink transmissions to a base station (BS) using one or more transmit power parameters. The one or more transmit power parameters are based, at least in part, on a transmission configuration of the one or more uplink transmissions. The method generally includes transmitting the one or more uplink transmissions to the BS using the determined transmit power.

A method, network node and aerial wireless device (AWD) for height based out of band emission control of the AWD are disclosed. A network node configured to communicate with an AWD is provided. According to one aspect, a network node is configured to signal emission control parameter information for modifying a transmission power of the AWD based at least in part on a height of the wireless device.

Systems and methods model earth stations and other captive terrestrial sites as simulated cell sites in a radio access network (RAN) to identify potential cellular network interferers with the earth stations. A computing device selects an earth station within a geographic area of a RAN segment and model the earth station as a cell within the RAN segment, wherein the modeling creates a simulated earth station cell. The computing device obtains sector carrier data for cells in the RAN segment and scores, based on the sector carrier data, neighboring cells to the simulated earth station cell. The scoring indicates a level of potential interference of the neighboring cells with the earth station based on geo-spatial relevance. The computing device identifies projected mobility interference in neighboring cells to the earth station and provides prioritization recommendations for interference mitigation for the earth station based on the scoring and the identifying.

Methods and systems are provided for determining frequency allocation. A first frequency band, a second frequency, and a third frequency band are ranked based at least in part on a sector power ratio (SPR). The first frequency band is determined to have a highest rank, which indicates that the first frequency band has a lowest SPR of frequency bands being ranked. Based on the first frequency band having the highest rank, the first frequency band and either the second frequency band or the third frequency band are assigned for carrier aggregation.
