Abstract
Apparatus and methods for power control for mitigation or control of interference in a wireless communications environment. Control techniques can consider the effect of interference on an access point and the access point can identify interfering wireless terminals and cause a message to be sent to a controlling access point of the interfering wireless terminal to cause the uplink power of the interfering wireless terminal to be adjusted.
Claims27
A method of operating a first access point, the method comprising:
- the first access point identifying a first wireless terminal that is a source of interference to the first access point;
- the first access point sending a first wireless-terminal specific message to the first wireless terminal's controlling access point identifying the first wireless terminal and to request a reduction in signal transmission power of the first wireless terminal, wherein the first wireless terminal is one of a plurality of wireless terminals that are not served by the first access point but that cause interference to the first access point;
- the first access point identifying one or more additional wireless terminals which are not being served by the first access point but which are causing interference to the first access point;
- and
- the first access point sending additional wireless-terminal specific messages to a controlling access point or points of the one or more additional wireless terminals identified to request a reduction in transmission power of one or more of the additional wireless terminals.
2 more elements
A first access point, comprising:
- a terminal identification module configured to identify a first wireless terminal that is a source of interference to the first access point;
- and
- a message generation module configured to send a first wireless-terminal specific message to the first wireless terminal's controlling access point identifying the first wireless terminal and to request a reduction in signal transmission power of the first wireless terminal, wherein the first wireless terminal is one of a plurality of wireless terminals that are not served by the first access point but that cause interference to the first access point, and wherein:
- the terminal identification module is further configured to identify one or more additional wireless terminals which are not being served by the first access point but which are causing interference to the first access point;
- and
- the message generation module is further configured to send additional wireless terminal specific messages to a controlling access point or points of the one or more additional wireless terminals identified to request a reduction in transmission power of one or more of the additional wireless terminals.
3 more elements
A non-transitory computer readable medium comprising computer executable instructions stored thereon, which, when executed control a first access point to perform the operations of:
- identifying a first wireless terminal that is a source of interference to the first access point;
- sending a first wireless-terminal specific message to the first wireless terminal's controlling access point identifying the first wireless terminal and to request a reduction in signal transmission power of the first wireless terminal, wherein the first wireless terminal is one of a plurality of wireless terminals that are not served by the first access point but that cause interference to the first access point;
- identifying one or more additional wireless terminals which are not being served by the first access point but which are causing interference to the first access point;
- and
- sending additional wireless-terminal specific messages to a controlling access point or points of the one or more additional wireless terminals identified to request a reduction in transmission power of one or more of the additional wireless terminals.
2 more elements
A first access point, comprising:
- means for identifying a first wireless terminal that is a source of interference to the first access point;
- means for sending a first wireless-terminal specific message to the first wireless terminal's controlling access point identifying the first wireless terminal and to request a reduction in signal transmission power of the first wireless terminal, wherein the first wireless terminal is one of a plurality of wireless terminals that are not served by the first access point but that cause interference to the first access point;
- means for identifying one or more additional wireless terminals which are not being served by the first access point but which are causing interference to the first access point;
- and
- means for sending additional wireless-terminal specific messages to a controlling access point or points of the one or more additional wireless terminals identified to request a reduction in transmission power of one or more of the additional wireless terminals.
