Abstract:
1. A method for use in a network based on Global System for Mobile Communications (GSM) Enhanced Data Rates for GSM Evolution (EDGE) Radio Access network (GERAN) technology, the method comprising: receiving capability information from a wireless transmit/receive unit (WTRU) that indicates whether the WTRU supports GERAN Orthogonal Sub-Channels (OSCs), wherein GERAN OSCs are implemented by multiplexing multiple WTRUs onto a single GERAN timeslot using a phase-shift-keying (PSK) modulation scheme; determining whether the WTRU should communicate using a GERAN OSC sub-channel based on: in response to a determination that the WTRU should communicate using the GERAN OSC sub-channel, transmitting an assignment message to the WTRU that indicates that the WTRU should communicate using the GERAN OSC.
