Abstract
A radiocommunication method and system which facilitates half-rate communications as well as downlink power control and selective beam transmission is described. Data associated with two terminals is multiplexed into a single timeslot. A first terminal's data occupies a first portion of the timeslot, while the second terminal's data occupies a second portion of the timeslot. A synchronization/training field may separate the first and second portions of the timeslot. In this way, a base station can change the power level and/or direction of transmission of the different terminal's data even though that data is multiplexed together on the same timeslot.
