Power control of point to multipoint physical channels
Abstract
A method and apparatus are used to determine an efficient transmit power for point to multipoint (PtM) transmissions by maintaining a database at a base station which specifies which of a plurality of wireless transmit/receive units (WTRUs) are members of each PtM group. The transmit power of each WTRU's downlink dedicated channel is adjusted to the minimum required power necessary and the PtM transmit power for each PtM group is set such that the PtM transmit power of a PtM group is equal to the greatest of a WTRU in the PtM group plus a PtM power offset.
