Problems solved by technology

For the above possible solutions, considering that the system information update itself does not occur frequently in the cell, therefore, in order to enable the UE to receive the system information that does not change frequently without configuring HSDPA resources for TS0 and TS6 of the secondary carrier, the actual The configuration and use flexibility of system resources have brought great restrictions, resulting in the inability to effectively utilize the resources of secondary carriers TS0 and TS6

Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0027] In order to solve the problems existing in the prior art and improve the utilization rate of secondary carrier resources, the present invention provides two scheduling methods for scheduling UEs working on secondary carriers in the enhanced CELL_FACH state. The two methods are described below The methods are described in detail separately.

[0028] The first scheduling method includes the following steps:

[0029] Step 1: Node B obtains the change time of the broadcast control channel and the maximum time required for the UE to read the updated system information;

[0030] Step 2: The Node B does not schedule slot 0 and slot 0 of the UE operating on the secondary carrier in the enhanced CELL_FACH state within the maximum time required for the UE...

Abstract

The invention discloses a scheduling method which is used for scheduling assistant carrier UE (user equipment) in a enhanced CELL_FACH state and comprises: a Node B acquires the change time of a broadcast control channel and the required maximum time for the UE to read the updated system information; and starting from the change time of the broadcast control channel and within the required maximum time for the UE to read the updated system information, the Node B does not schedule the time slot 0 and time slot 6 of the assistant carrier UE in the enhanced CELL_FACH state. The invention also provides another scheduling method. By using the method provided by the invention, the resources of the time slot 0 and time slot 6 of the assistant carrier can be fully and efficiently utilized, and the system information at the time slot 0 of a main carrier can be normally received.

Description

technical field [0001] The present invention relates to TD-SCDMA technology, in particular to a scheduling method, which is used for scheduling UEs working on secondary carriers in enhanced CELL_FACH state. Background technique [0002] In TD-SCDMA HSPA+, when the terminal is in the enhanced CELL_FACH state, it can work on the secondary carrier. The terminal needs to receive system information in the CELL_FACH state, and the system information is broadcast on time slot 0 (hereinafter referred to as: TS0 ) of the main carrier. Limited by the existing terminal radio frequency devices, it takes a certain amount of time for the terminal to switch from one frequency point to another. The time slot 6 (hereinafter referred to as: TS6) of the time slot 6 (hereinafter referred to as: TS6) receives data, and due to the above restrictions, the terminal cannot receive the system information on TS0 of the main carrier normally at the same time. [0003] In addition, in HSPA+, the high-...
