Abstract
A method for using orthogonal sub-channels (OSCs) in a wireless transmit/receive unit (WTRU). A capability report is received from the WTRU, including an indication whether the WTRU supports OSCs. A determination is made whether to use OSCs for the WTRU and the result of the determination is signaled to the WTRU. If OSCs are used with the WTRU, the signaling includes an OSC assignment for the WTRU. In one embodiment, two resources are assigned to the WTRU and each resource is assigned to a different OSC.
Claims18
A method for communicating wireless data in Global System for Mobile Communications/Enhanced General Packet Radio Service (EGPRS) Dual Transfer Mode (DTM), the method comprising:
- a wireless transmit/receive unit (WTRU) communicating circuit-switched (CS) voice data on a first Orthogonal Sub-Channel (OSC) on a timeslot in a first frame,
- wherein the CS voice data is associated with a half rate traffic channel (TCH/H), and
- wherein the TCH/H is part of a DTM resource allocated to the WTRU;
- and
- the WTRU communicating packet data on a second OSC on the timeslot in a second frame that is subsequent to the first frame,
- wherein the packet data is associated with a half rate packet data traffic channel (PDTCH/H), and
- wherein the PDTCH/H is part of the DTM resource allocated to the WTRU.
A wireless transmit/receive unit (WTRU) capable of communicating using Global System for Mobile Communications/Enhanced General Packet Radio Service (EGPRS) Dual Transfer Mode (DTM), the WTRU comprising:
- a transceiver configured to communicate circuit-switched (CS) voice data on a first Orthogonal Sub-Channel (OSC) on a timeslot in a first frame,
- wherein the CS voice data is associated with a half rate traffic channel (TCH/H), and
- wherein the TCH/H is part of a DTM resource allocated to the WTRU;
- wherein the transceiver is further configured to communicate packet data on a second OSC on the timeslot in a second frame that is subsequent to the first frame,
- wherein the packet data is associated with a half rate packet data traffic channel (PDTCH/H), and
- wherein the PDTCH/H is part of the DTM resource allocated to the WTRU.
A method for communicating wireless data in Global System for Mobile Communications/Enhanced General Packet Radio Service (EGPRS) Dual Transfer Mode (DTM), the method comprising:
- a wireless transmit/receive unit (WTRU) communicating circuit-switched (CS) voice data on a first Orthogonal Sub-Channel (OSC) on a first timeslot in a frame,
- wherein the CS voice data is associated with a full rate traffic channel (TCH/F), and
- wherein the TCH/F is part of a DTM resource allocated to the WTRU;
- and
- the WTRU communicating packet data on a second OSC on a second timeslot in the frame,
- wherein the packet data is associated with a full rate packet data traffic channel (PDTCH/F), and
- wherein the PDTCH/F is part of the DTM resource allocated to the WTRU.
The method of claim 14, further comprising:
- receiving information from a base station that indicates that the first OSC and the second OSC are assigned to the WTRU;
- wherein the communicating the CS voice data and the communicating the packet data are performed based on the information from the base station.
