    Abstract: Transmit power (e.g., maximum transmit power) may be defined based on the maximum received signal strength allowed by a receiver and a total received signal strength from transmitting nodes at the receiver. Transmit power may be defined for an access node (e.g., a femto node) such that a corresponding outage created in a cell (e.g., a macro cell) is limited while still providing an acceptable level of coverage for access terminals associated with the access node. An access node may autonomously adjust its transmit power based on channel measurement and a defined coverage hole to mitigate interference and perform a self-calibration process.

    Abstract translation: 可以基于接收机允许的最大接收信号强度和来自接收机处的发射节点的总接收信号强度来定义发射功率（例如，最大发射功率）。 可以为接入节点（例如，毫微微节点）定义发射功率，使得在小区（例如，宏小区）中创建的相应中断受到限制，同时仍然为与接入节点相关联的接入终端提供可接受的覆盖水平 。 接入节点可以基于信道测量和定义的覆盖孔来自主地调整其发射功率以减轻干扰并执行自校准过程。

    Abstract: Transmit power for an access point is controlled based on information received by the access point. For example, an access point may employ one or more algorithms that use messages received from nearby access terminals to maintain an acceptable tradeoff between providing an adequate coverage area for access point transmissions and mitigating interference that these transmissions cause at nearby access terminals. Here, the access point may employ a network listen-based algorithm upon initialization of the access terminal to provide preliminary transmit power control until sufficient information is collected for another transmit power control algorithm (e.g., an access terminal assisted algorithm). Also, the access terminal may employ an active access terminal protection scheme to mitigate interference the access point may otherwise cause to a nearby access terminal that is in active communication with another access point.

    Abstract: Described features are directed to staggered frequency channel changing for cells of spectrum sharing networks. In some examples users communicating on one or more frequency channels of a spectrum sharing network may receive an indication that those channels are to be vacated, for example that the frequency channels are not to be transmitted on, or otherwise used for communications. Cells of the spectrum sharing network may receive the indication and perform staggered (e.g., sequential or randomly-timed) channel changes. The staggered channel changes may facilitate handover of user devices of the spectrum sharing network by, for example, reducing a number of cells that are simultaneously undergoing a channel change procedure. Thus, staggered frequency channel changing may reduce user service interruptions and radio link failures in a spectrum sharing network.
