Abstract

A system and method for physical shared channel allocation in a UMTS wireless communication system. A physical shared channel allocation message ( 220 ) is sent containing a plurality of occurrences of allocated physical resources and TFCS IDs; and, at a radio unit ( 130 A), the sent physical shared channel allocation message is received and the plurality of occurrences of allocated physical resources and TFCS IDs contained therein are processed, thereby allowing a plurality of CCTrCHs to be allocated with a single physical shared channel allocation message ( 220 ).
