ABSTRACT:
An apparatus and method exploits a variable frequency response of a radio channel in a time division duplex wireless communication system such that for unscheduled uplink transmissions, the transmission power required for correct reception of the data is minimized. The degree of interference caused to other users in both the serving cell and the neighbor cells is correspondingly reduced and hence system capacity is improved.
