Abstract
A method, apparatus and system for modifying a transmit diversity signal comprising receiving at least one input parameter, calculating at least one virtual parameter based on the at least one input parameter, converting the at least one virtual parameter into an actual parameter, and modifying a transmit diversity signal based on the actual parameter. Variations of the invention are possible, including mapping the input parameter to an actual parameter by various methods, for example, quantization, hysteresis and other methods. Embodiments of the invention may include an apparatus adapted to modify a transmit diversity signal comprising a processor to calculate at least one virtual parameter based on at least one input parameter, convert said at least one virtual parameter to an actual parameter, and modify said transmit diversity signal based on said actual parameter.

41. A method for adjusting a wireless transmission signal transmitted by a mobile device, the method comprising the steps of:
-
transmitting a first paired signal set, said paired signal set including a first signal from a first antenna and a second signal from a second antenna, said paired signal set comprising signals differing by a first diversity parameter and directed to a base station, receiving at least one input parameter from said base station; calculating at least one virtual parameter based on said at least one input parameter; converting said at least one virtual parameter into an actual parameter, wherein said actual parameter corresponds to a value of an adjustment of the first transmit diversity parameter; and forming a second paired signal set, said second paired signal set formed by signals differing by the value of a second transmit diversity parameter, said second transmit diversity parameter determined by changing said first diversity parameter by an amount determined by the adjustment of the first diversity parameter; and transmitting said second paired signal set. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59)

60. A mobile subscriber unit apparatus adapted to improve performance of a paired signal set comprising signals differing by a first diversity parameter and directed to a base station comprising:
a processor to calculate at least one virtual parameter based on at least one input parameter received from a base station, convert said at least one virtual parameter to an actual parameter, wherein said actual parameter corresponds to a value of a transmit diversity parameter, and cause the transmit power level of a first transmit signal in a paired signal set transmitted by a first antenna of the mobile subscriber unit apparatus to be modified with respect to a second transmit signal in said paired signal set transmitted by the second antenna of the mobile subscriber unit apparatus by parameter by an amount determined by the adjustment of the first diversity parameter. - View Dependent Claims (61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74)
