Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] see figure 2 , which is a flow chart of a method for extending a shared data channel in a multi-frequency HSDPA communication system, which includes:

[0025] S110: Select one carrier among all carriers in the same cell as the main carrier, and other carriers as auxiliary carriers. The TS0 time slot of the main carrier is used to send system broadcast information, and the TS0 time slot of the auxiliary carrier is used for data transmission of the shared data channel ;

[0026] S120: Each user terminal supporting HSDPA in the cell reports its own terminal capability information to the network side, and the terminal capability information includes whether the own terminal has the capability of using the secondary carrier TS0 time slot for sharing a data channel;

[0027] S130: The network side notifies the service terminal that needs to perform data communica...

Abstract

The method comprises: a) selecting one carrier wave from all carrier waves as the main carrier wave; other carrier waves are used as auxiliary carrier waves; the time slot of main carrier TSO is used to send system broadcast information, and the time slot of auxiliary carrier wave is used to transmit data in shared data channel; b) in the cell, each user terminal supporting HSDPA reports the information about its terminal capacity to the network side; the terminal capacity information includes the message of which whether or not the current terminal has auxiliary carrier wave capacity that can be used in the shared data channel; c) in each scheduling cycle, the network side send the information about whether or not the TSO time slot of auxiliary carrier wave is included in the shared data channel resources allocated by the serving terminal to the serving terminal that will be used to make data communication in next cycle through the downlink control channel.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for expanding a shared data channel in a multi-frequency point HSDPA communication system. Background technique [0002] In a multi-frequency point communication system, there are multiple carriers in a cell: one primary carrier and at least one secondary carrier. For a multi-frequency TD-SCDMA communication system, the network side has the ability to simultaneously modulate or demodulate information on more than two frequency points, and the user terminal may have a single receiver or multiple receivers (such as a user terminal with dual receivers). If there is only a single receiver, the user terminal can only demodulate information of one frequency point at the same time. [0003] see figure 1 , which is a schematic diagram of a physical layer frame structure in an existing single-carrier TD-SCDMA communication system. The physical layer of the TDD system adopts a three-...
