Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method and apparatus for control channel allocation in GERAN using the concept of orthogonal sub channels.

SOLUTION: The quality of control signaling is improved on the basis of signaling messages controlling speech or data transmission over an air interface between at least two Multi-User-Reusing-One-Slot/ Voice Services Over Adaptive Multiuser Channels On One Slot (MUROS/VAMOS) capable wireless transmit/receive units (WTRUs). The WTRUs communicate with each other at the physical layer via signaling messages transmitted in control channels such as Slow Associated Control Channel (SACCH). The SACCH occurrences for MUROS/VAMOS multiplexed users are misaligned or shifted.
