Abstract
A method for performing power control in a wireless communication unit (112) operating in a wireless communication system (100), includes the steps of: determining (315) a path loss correlation metric to derive one or more parameters pertaining to a wireless transmission; and adjusting an output power level of said wireless communication unit in response to said one or more parameters. Basing power control calculations on a path loss correlation metric provides the advantage of improved power control performance particularly for slow moving subscriber equipment without compromising power control performance at high speed.
Claims36
A method for performing power control in a wireless communication unit operating in a wireless communication system, the method comprising:
- determining a plurality of path losses for a wireless transmission, each path loss corresponding to one of a plurality of wireless transmission times;
- deriving at least one parameter from a correlation between or among at least two of the plurality of path losses;
- and
- adjusting an output power level of said wireless communication unit in response to said at least one parameter.
A wireless communication system comprising:
- power control processing means, further comprising:
- means for determining a plurality of path losses for a wireless transmission, each path loss corresponding to one of a plurality of wireless transmission times;
- means for deriving at least one parameter from a correlation between or among at least two of the plurality of path losses;
- and
- adjustment means to adjust an output power level of said wireless communication unit in response to said at least one parameter.
A wireless communication unit capable of performing power control when operating in a wireless communication system, the wireless communication unit comprising:
