A method for a wireless router to adjust a state of a wireless network provided by the wireless router, includes: monitoring whether the state of the wireless network satisfies an adjusting condition of adjusting the state of the wireless network; when the state of the wireless network satisfies the adjusting condition, sending an adjusting prompt to a wireless terminal, the adjusting prompt being configured to ask for user permission to adjust the state of the wireless network; and if the wireless router receives from the wireless terminal an acceptance instruction to accept the adjusting, adjusting the state of the wireless network.

A wireless device receives configuration parameters indicating a first PDSCH processing capability value associated with a first power state of a cell, and a second PDSCH processing capability value associated with a second power state of the cell. The first PDSCH processing capability value indicates a first applicable gap between receiving a TB and transmitting an acknowledgement when the cell is in the first power state. The second PDSCH processing capability value indicates a second applicable gap between receiving a TB and transmitting an acknowledgement when the cell is in the second power state. A first TB is processed based on the first PDSCH processing capability value, when the cell in the first power state. A command is received indicating transitioning to the second power state. A second TB is processed based on the second PDSCH processing capability value, in response to transitioning to the second power state.

There is provided a communication control device including a power distribution unit configured to distribute, to one or more secondary systems, a transmission power accepted for a secondary usage of a frequency channel which is protected for a primary system, and a notification unit configured to notify each secondary system of a value of a second transmission power which is decided depending on a value of a first transmission power distributed by the power distribution unit. Upon updating the transmission power, only in a case where a value of the second transmission power which is previously notified and a value of the first transmission power which is newly distributed by the power distribution unit satisfy a predetermined condition with respect to a certain secondary system, the notification unit notifies the secondary system of a new value of the second transmission power.

Various aspects of the disclosure relate to event triggers for independent links. For example, an event trigger may be based on measurements from multiple links. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, an event trigger may be based on aggregated measurements from multiple links.

A subscriber unit, including an antenna array and an antenna array interface coupled to the antenna array, is described. Wireless transmissions, at least two of which are based on different directional transmissions from a transmitter, are received at the antenna array. Feedback messages are generated using the antenna array interface. The feedback messages are communicated using the antenna array to adjust settings of the transmitter.

An object is to appropriately perform transmission power control on a mobile station (UE) when performing “Inter-eNB CA” by using cells under the control of plural radio base stations (eNB). In a mobile communication system according to the present invention, each of plural radio base stations (eNB#1, eNB#2) reduces, upon detecting that the mobile station (UE) is performing transmission at a maximum transmission power (P.sub.CMAX, c), by a predetermined amount a transmission power of the mobile station (UE) in a cell (#1/#2A to #2C) under the control thereof and notifies other radio base station (eNB) of the predetermined amount.
