Patent ID: 8014343

Claim:
A method for detecting an overlap of an enhanced dedicated channel (E-DCH) transmission from a wireless transmit/receive unit (WTRU) and a Node B assigned uplink compressed mode transmission gap, the method comprising: obtaining a current system frame number (SFN) and a concerned subframe number (SubFN) for the E-DCH transmission; determining whether the SFN for the E-DCH transmission is a compressed frame using an uplink compressed frame gap description map; computing a first subframe time slot, N e-st-first , and a last subframe time slot, N e-st-last , using the concerned SubFN for the E-DCH transmission; determining a compressed gap type of the SFN for the E-DCH transmission using the uplink compressed frame gap description map; determining whether the compressed gap type is a single-frame gap or a double-frame gap; determining whether there is an overlap of an E-DCH transmission upon a condition that the compressed gap type is a single frame gap; determining whether the SFN is a first frame or a second frame in a double frame gap upon a condition that the SFN for the E-DCH transmission is a double frame gap type; and determining whether there is no E-DCH transmission overlap upon a condition that SFN is the first frame in the double frame gap and the last time slot, N e-ts-last , in the concerned SubFN is less than a first idle time slot, N first , in the uplink compressed mode transmission gap.
