The exemplary embodiments of this invention provide in one aspect thereof
a method that comprises assuming that a user k is scheduled in M
transmission time intervals during a radio resource indication period of
N transmission time intervals, where M.ltoreq.N, where an effective
average power used by the user k is expressed as: P k = 1 N
.times. m = 1 M .times. P k ' .function. ( m ) ,where
P'.sub.k(m) denotes the transmit power that is used by user k for each of
the M transmission time intervals where user k is scheduled; and
estimating a required downlink shared channel power for a scheduling
priority indicator number x so as to fulfill a guaranteed bit rate as:
P SPI .function. ( x ) = k .di-elect cons. SPI .function. ( x
) .times. P k .times. GBR k RB k ,where RB.sub.k is an
average bit rate supported to the user k over a past radio resource
indication period, GBR.sub.k is a guaranteed bit rate for the user k, and
SPI(x) is a set of users that have SPI=x.
