Description

A method for activating a secondary carrier, a terminal, and a priority of a Chinese patent application filed on August 21, 2011, the Chinese Patent Office, Application No. 201110241314.7, entitled "Secondary Carrier Activation Method, Terminal, and Base Station", The entire contents of this application are incorporated herein by reference.

Technical field

The present invention relates to the field of wireless communications, and in particular, to a method, a terminal, and a base station for a secondary carrier activation in a multi-carrier forward access channel state. Background technique

The secondary carrier activation method in the multi-carrier DCH (Dedicated Channel) state is: The base station sends an HS-SCCH (High Speed Shared Control Channel) command to the terminal, and the command carries the activated secondary carrier. The indication, and the number of the secondary carrier to be activated, the terminal returns an activation response to the base station to inform the base station whether to confirm activation of the secondary carrier. The carrier that is configured with the HS-DPCCH (High Speed Dedicated Physical Control Channel) is called the primary carrier and is also called the primary cell. The carrier that is not configured with the HS-DPCCH is called the secondary carrier. Also called the secondary community.

However, in the multi-carrier FACH (Forward Access Channel) state, the uplink transmission is performed by using a Common E-DCH (Common Enhanced-Dedicated Channel). The Common E-DCH needs to be competed before use or directly assigned to the terminal by the base station. However, in the initial state, the terminal does not compete for the uplink channel, and no uplink resources are available. Therefore, if the secondary carrier activation mode is adopted in the multi-carrier DCH state, the base station will not receive the active response after the HS-SCCH command is sent, so that the network side cannot determine whether the terminal activates the secondary carrier. Therefore, in the multi-carrier FACH state, how to enable the network side to know whether the terminal activates the secondary carrier, there is no corresponding solution in the prior art.
