A method of managing an Evolved Packet System (EPS) fallback procedure in a 5GS network. The method comprises making available to the Access Mobility Function (AMF), a configuration parameter per Public Land Mobile Network (PLMN) indicating if early or late PCRF/PCF interaction with the IMS is used. Then, upon receipt by the network of a 5GS network registration request from a UE, the home PLMN of the UE is identified as is the configuration parameter for that PLMN. The identified parameter is then used to determine for the UE whether or not EPS fallback is available to the UE, and an indication of the determination is sent to the UE.

The present disclosure provides a method of controlling an output power of a terminal during a carrier aggregation operation and an apparatus suitable for the method. During the carrier aggregation operation, the terminal may control the power allocation such that more transmission power is allocated for the primary cell when there exists a bearer established already for a particular service such as the VoLTE service, so as to facilitate high quality services according to a service using situation of the terminal.

Methods and systems for Sidelink Transmit Power Control may include but are not limited to path loss estimation for sidelink including Reference Signals (RS) for path loss measurement and path loss estimation for proximity based transmit power control, open-loop transmit power control on sidelink including synchronization, discovery, and broadcast, as well as closed-loop transmit power control on sidelink including two-way transmit power control on sidelink for unicast and two-way transmit power control on sidelink for groupcast or multicast. Methods and systems for transmit power sharing may include but are not limited to transmit power sharing between uplink and sidelink and transmit power sharing between sidelinks.

A wireless device receives: a first maximum total transmit power allowed for a first cell group of a first type of radio access technology; and a second maximum total transmit power allowed for a second cell group of a second type of radio access technology. It is determined that a total transmission power exceeds a value based on: a first power for transmission of first uplink signal(s) via the first cell group, and a second power for transmission of second uplink signal(s) via the second cell group. The first and second powers are less than or equal to the first and second maximum total transmit powers respectively. Scheduled transmission of the first uplink signal(s) of the first cell group is dropped in response to the first cell group being of the first type of radio access technology. Second uplink signal(s) are transmitted to a base station.

Techniques for uplink power control (e.g., for New Radio (NR)) are disclosed. A wireless transmit/receive unit (WTRU) may determine that the WTRU is to perform a first and a second transmissions using a first and a second transmission beams. The WTRU may determine an uplink transmission power for one or more of the first or second transmissions. For example, if the angular separation of the first and the second transmission beams is greater than a first separation threshold, the WTRU may determine the uplink transmission power having a first maximum power level parameter and a second maximum power level parameter. If the angular separation of the first and the second transmission beams is less than a second separation threshold, the WTRU determine the uplink transmission power having a shared maximum power level parameter. The WTRU may transmit the first and second transmissions using the first and second transmission beams, respectively.

Facilitating real-time power optimization in advanced networks (e.g., 5G, 6G, and beyond) is provided herein. Operations of a method can include determining, by a system comprising a memory and a processor, a power distribution setting for a user equipment that includes multiple radios based on a historical radio power usage, a historical performance result, a current location, and an application currently executing on the user equipment. The method also can include implementing, by the system, the power distribution setting across the multiple radios of the user equipment. The first radio of the multiple radios can be a first radio type and a second radio of the multiple radios can be a second radio type, different from the first radio type.

A terminal computer includes a processor and a memory. The memory stores instructions executable by the processor to determine an initial power back-off value for establishing a communication link to a satellite as a function of a distance of a location of a satellite terminal antenna within a satellite beam footprint from a specified reference point within the satellite beam footprint, and to initiate communication with the satellite based on the determined initial power back-off value.

Example implementations relate to adjusting power states of access points based on a power model. A non-transitory computer readable medium may store instructions executable by a processing resource to: in response to a client device being associated with an access point (AP) of a group of APs, determine: a first degree of performance being provided to the client device via a first radio of the AP of a group of APs; and a second degree of performance to be provided to the client device via a second radio of the group of APs, if the client device is provided a network connectivity via the second radio; determine, based on the first degree of performance and the second degree of performance, a subset of the group of APs whose power state is adjustable to a different power state; and adjust a power state of the subset of the group of APs.

Systems and methods to accomplish a power control system in a MANET are described herein. To reduce detectability of the MANET, the controller 310 can reduce transmit power at individual links while operating the link's modulation and coding data rate and data queue backlog at levels that are sufficient to meet the user's offered load.

Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas associated with different power classes. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. The local and auxiliary antennas may be associated with different power classes, and the first device may transmit a message to a base station indicating that the first device is capable of transmitting using antennas associated with different power classes. The first device may then receive configurations from a base station of different transmit powers to transmit on the antennas associated with the different power classes, and the first device may transmit uplink signals to the base station in accordance with the different transmit power configurations.
