Method of and system for wireless communication

A system, comprising:

• a base station;
• and
• a plurality of mobile stations,
• wherein said base station is configured to transmit at least one transmission to be received by at least one of said plurality of mobile stations to provide a point to multipoint transmission,
• wherein said at least one of said plurality of mobile stations comprises a transmission determination unit configured to determine whether said at least one transmission which is received by said at least one mobile station satisfies predetermined criteria,
• wherein said base station comprises a power level unit configured to determine when said base station is to change a power level with which said base station transmits said at least one transmission to said plurality of mobile stations in said point to multipoint transmission, depending upon a determination made by said at least one of said plurality of mobile stations, and further configured to change said power level with which said base station transmits power when said power level unit determines that said power level is to be changed,
• wherein said power level unit is configured to determine when information has been received indicating that said predetermined criteria has not been satisfied and to determine whether increasing said power level with which said base station transmits said at least one transmission would improve reception of said at least one transmission by said at least one mobile station, and
• wherein when no information is received, said power level unit of said base station is further configured to reduce said power level with which said base station transmits.

An apparatus, comprising:

• a power level unit configured to determine when a base station is to change a power level with which said base station transmits at least one transmission to a plurality of mobile stations in a point to multipoint transmission, depending on information received from at least one of said plurality of mobile stations as to whether said at least one transmission satisfies predetermined criteria;
• and further configured to change said power level with which said base station transmits when said power level unit determines that said power level is to be changed,
• wherein said power level unit is further configured to determine when information has been received indicating that said predetermined criteria has not been satisfied, and to determine whether increasing said power level with which said base station transmits said at least one transmission would improve reception of said at least one transmission by said at least one of said plurality of mobile stations, and
• wherein when no information is received, said power level unit of said apparatus is further configured to reduce said power level with which said base station transmits.

A method, comprising:

• receiving at a base station information from at least one of a plurality of mobile stations, said information indicating whether at least one transmission transmitted by said base station satisfies predetermined criteria;
• determining, at a power level unit and in response to said received information, when a base station is to change a power level with which said base station transmits said at least one transmission to said at least one mobile station in a point to multipoint transmission;
• and
• changing said power level with which said base station transmits power when said determining determines that said power level is to be changed,
• wherein said determining comprises determining at the power level unit whether increasing said power level with which said base station transmits said at least one transmission would improve reception of said at least one transmission by said at least one mobile station;
• the method further comprising setting up a point to point connection between said base station and one of said mobile stations when said point to multipoint connection between said base station and said one of said mobile stations falls below a given quality level.
