1. An apparatus comprising:

  • a transmitter; and

    a processor configured to;

    categorize each wireless transmit receive unit (WTRU) of a plurality of WTRUs on the basis of an association of each WTRU with at least one of a plurality of point to multipoint (PtM) channels, wherein groups of WTRUs from the plurality of WTRUs are associated with each PtM channel;

    adjust a transmit power level of each downlink (DL) channel associated with the plurality of WTRUs; and

    set a PtM channel transmission power level for each of the groups of WTRUs, wherein the transmission power level for each PtM channel equals the DL channel transmit power level required for one of the WTRUs of the group of WTRUs associated with the PtM channel adjusted by an offset parameter;

    wherein the transmitter is configured to produce a PtM channel having the transmission power level.
