Patent ID: 7890114

Claim:
A method of sending first and second signals to a plurality of user equipments, the method comprising: providing a dedicated channel for each one of the plurality of user equipments, providing a code-multiplexed shared channel for the plurality of user equipments, splitting the plurality of user equipments substantially evenly into a first group of user equipments which are assigned to a first carrier frequency and into a second group of user equipments which are assigned to a second carrier frequency, receiving first signals which are to be transmitted on dedicated channels being assigned to the first carrier frequency to provide two first signal components for transmit diversity; receiving second signals which are to be transmitted on dedicated channels being assigned to the second carrier frequency to provide two second signal components for transmit diversity; first code-multiplexing third signals to be sent to the first group of user equipments to provide two third signal components for multi-user diversity; second code-multiplexing fourth signals to be sent to the second group of user equipments to provide two fourth signal components for multi-user diversity; first adding one of the first signal components, one of the second signal components, one of the third signal components, and one of the fourth signal components; second adding the other one of the first signal components, the other one of the second signal components, the other one of the third signal components, and the other one of the fourth signal components; and first power-amplifying a result of the first adding to transmit the first power-amplified signal via a first antenna; second power-amplifying a result of the second adding to transmit the second power-amplified signal via a second antenna; wherein the first carrier frequency and the second carrier frequency are alternately assigned to the plurality of user equipments in an order in which the plurality of user equipments become active, wherein each of the first and second signals is assigned to either the first carrier frequency or to the second carrier frequency, wherein each of the user equipments is assigned to one of the first and second carrier frequencies and to one of the first and second antennas, wherein the first and second signals are real time signals and the third and fourth signals are non-real time signals, the real time signals including at least one of voice signals and video signals.
