't can be seen in Table C.-=- that the freAuency separation between the uplin# and downlin# is larer than the -, M>!channel bandwidth/ hence the 1$ transmitted carrier is outside the adjacent channel selectivity (02$) reion of the 1$receive freAuency/ and thus the 1$ in=band eneral bloc#in reAuirement is used here for the analysis.

"0 has specified =3 d1m for the interferin sinal power of the 1$ in=band bloc#in reAuirement in order toachieve a maimum of ; d1 victim 1$ receiver desensiti!ation in Table ! uplin# channel bandwidth and : M>! in=band

bloc#er. This reAuirement means that the minimum rejection by the 1$ receiver '8 and baseband filters on the in=bandbloc#er is :.! interferer. This reAuirement is applicable to both uplin# pairin options. ote that thecalculation in Table C.+=- is also valid for -,/ -: or +, M>! channel bandwidth because the same referencemeasurement channel as for : M>! channel bandwidth is specified for the in=band eneral bloc#in reAuirement.
