Problems solved by technology

In the previous discussion, the solution of fast switching small cells has been proved to obtain optimal system performance. However, fast small cell switching will affect the measurement and other behaviors of the terminal. When the terminal knows the status information of the small cell , that is, whether the small cell is currently on or off, and the terminal needs to further know the duration information of the small cell in the current state

Embodiment approach

[0108] In addition, since the DRS (Dedicated Reference Signal, dedicated reference information) transmission in the off state is introduced in Rel-12 under the small cell on / off mechanism, the subframe position of the DRS transmission is notified to the terminal in advance . Therefore, when performing pilot detection, the terminal needs to determine whether the current subframe is a subframe for DRS transmission. In one implementation method, if the terminal detects that there is some kind of pilot transmission on the Scell ​​in the current subframe, and the terminal judges that the subframe is a DRS transmission subframe, then even if the terminal detects the transmission of the pilot, The terminal still considers that the Scell ​​is in the off state in the subframe.

[0109] Based on this method, the terminal needs to detect the presence or absence of pilot transmission on the Scell ​​in each subframe in the activated state.

Abstract

The present invention provides a method for determining the duration of the fast switching state of a micro cell base station, a system for determining the duration of the fast switching state of a micro cell base station, and a terminal, wherein the fast switching state of the micro cell base station is The method for determining the duration includes: when the micro cell base station is a micro cell base station switched at the single subframe level, detecting the switching state of the micro cell base station in real time to determine the state duration of the micro cell base station; When the micro cell base station is a micro cell base station with multi-subframe level switching, the state duration of the micro cell base station is determined by receiving a notification message sent by the micro cell base station or the macro cell base station. Through the technical solution of the present invention, the terminal can further know the duration information of the micro cell in the current state while knowing the current switch state of the micro cell base station, thereby avoiding invalid detection by the terminal and reducing the power consumption of the terminal .

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to a method for determining the duration of a fast switching state of a micro cell base station, a system for determining the duration of a fast switching state of a micro cell base station, and a terminal. Background technique [0002] In the current wireless communication system, in order to further increase the capacity of the network, the miniaturization of the base station and the densification of the network nodes have become an inevitable choice. However, the densification of network nodes will inevitably bring about the problem of mutual interference, and strong interference between nodes will greatly affect the performance of the system. [0003] In order to solve the interference problem between low-power nodes, 3GPP has done a lot of standardization work. In the R10 / 11 stage, the ABS (Almost Blank Subframe, almost blank subframe) method is introduced for ...
