Patent ID: 8259773

Claim:
A method implemented in a transmission device, comprising: encoding, in the transmission device, at least one first symbol; encoding, in the transmission device, at least one second symbol using a coding sequence having a cyclic correlation property so that the coding sequence is generated using a cyclic shift of an initial sequence; providing, during a transmission time interval (TTI), said at least one first encoded symbol through a switch that is set in a first mode when a hybrid automatic repeat request (HARQ) process identifier associated with the TTI indicates that dedicated time or frequency resources are used during the TTI and providing said at least one second encoded symbol through the switch that is set in a second mode when the HARQ process identifier associated with the TTI indicates that shared time or frequency resources are used during the TTI; transmitting, during the TTI, a radiofrequency signal indicative of said at least one encoded first symbol using dedicated time or frequency resources when the switch is in the first mode; and transmitting, during the TTI, the radiofrequency signal indicative of said at least one encoded second symbol using shared time or frequency resources when the switch is in the second mode.
