SIGNAL TRANSMISSION SCHEME FOR EFFICIENT MANAGEMENT OF COMMON ENHANCED DEDICATED CHANNEL
First Claim
1. A method for transmitting signals to a Node B by a User Equipment (UE) using a Hybrid Automatic Repeat Request (HARQ) scheme, the method comprising:
- transmitting a Medium Access Control Protocol Data Unit (MAC PDU) including first scheduling information and data to the Node B;
determining whether or not a Total E-DCH Buffer Status (TEBS) field of the first scheduling information is set to 0 when the transmission of the MAC PDU has failed;
triggering second scheduling information as new scheduling information when the TEBS field of the first scheduling information is not set to 0; and
transmitting the second scheduling information to the Node B.

Abstract
A signal transmission scheme for efficient management of a common E-DCH is provided. In the case of a common E-DCH that a UE in an idle mode or in a CELL_FACH status uses within a limited period of time, the UE may notify a Node B of release of radio resources of the common E-DCH using scheduling information including TEBS=0 within the period of time when the UE has completed data transmission. It is possible to prevent unnecessary waste of resources and unnecessary battery consumption of the UE by taking into consideration the above circumstances when triggering new scheduling information since HARQ transmission of the scheduling information has failed.

8. A User Equipment (UE) for transmitting signals to a Node B using a Hybrid Automatic Repeat Request (HARQ) scheme, the UE comprising:
-
a HARQ entity for managing one or more HARQ processes and controlling HARQ transmission of signals to the Node B; and a transmission module for transmitting a Medium Access Control Protocol Data Unit (MAC PDU) including first scheduling information and data to the Node B in association with a specific one of the one or more HARQ processes, and wherein the HARQ entity determines whether or not a Total E-DCH Buffer Status (TEBS) field of the first scheduling information is set to 0 when the transmission of the MAC PDU has failed and triggers second scheduling information as new scheduling information when the TEBS field of the first scheduling information is not set to 0, and transmits the second scheduling information to the Node B through the transmission module. - View Dependent Claims (9, 10, 11, 12, 13, 14)
