Abstract

A data transmission method includes receiving information about a plurality of shared control channels, selecting at least one of the plurality of shared control channels using a User Equipment (UE) identity, receiving a message indicating the use of a shared data channel through the selected shared control channel, and receiving data through the shared data channel according to the message. When receiving a RRC message, such as a RRC connection setup message, transmitted through a shared data channel, a user equipment can decide a shared control channel to be monitored.

Claims

1. A method of performing, by a user equipment, a radio resource control (RRC) procedure in a wireless communication system, comprising:

receiving system information including information about a plurality of high speed shared control channels (HS-SCCHs) from a network, the HS-SCCH being a high speed physical channel for transmitting control information regarding the reception of data through a shared data channel;

transmitting a RRC connection request message to the network;

selecting at least one of the plurality of HS-SCCHs using a user equipment (UE) identity, the selected HS-SCCH having an index of;

the UE identity mod K,

where K is given by the system information;

monitoring the selected HS-SCCH periodically;

receiving an instruction message indicating the use of the shared data channel through the selected HS-SCCH from the network; and

receiving a RRC connection setup message through the shared data channel according to the instruction message from the network.

2. The method of claim 1, wherein the system information is received through a broadcasting channel.

3. The method of claim 1, wherein the shared data channel is a High Speed-Downlink Shared Channel (HS-DSCH).

4. The method of claim 1, wherein the UE identity is one of International Mobile Station Identity (IMSI), Temporary Mobile Subscriber Identity (TMSI) and Radio Network Temporary Identity (RNTI).

5. The method of claim 1, further comprising transmitting a random access preamble on a random access channel (RACH) to request radio resources for the transmission of the RRC connection request message before transmitting the RRC connection request message.
