Embodiment Construction

[0054] Multiple embodiments of the present invention provide several feasible solutions to ensure user equipment processing capability in bidirectional connections. Specifically, when MeNB (macro eNB, also called macro base station) decides to configure a small cell to establish dual connectivity for user equipment, MeNB should notify SeNB (small eNB, also called small base station) of information related to the capability of user equipment. When the small base station obtains information related to the capabilities of the user equipment, it can reasonably allocate resources to the user equipment after considering the processing capabilities of the user equipment, so as to avoid the transmission of the macro base station and the small base station to the user equipment under dual connectivity Overdose can cause transmission failure.

Abstract

The present invention discloses methods and apparatuses for scheduling user equipment in a wireless communication system supporting dual connectivity, wherein the user equipment remains connected to both of two base stations in the dual connectivity, and the two base stations include a macro base station and a small base station, the method comprising: sending a dual connectivity setup request message from the macro base station to the small base station, wherein the dual connectivity setup request message comprises information related to user equipment capability, and the information is used by the small base station to perform resource schedule for the user equipment in the connectivity with the user equipment and enabling the macro base station to use the information to perform resource schedule for the user equipment in the connectivity with the user equipment. With the methods and apparatuses of the present invention, the resources may be reasonably allocated to the user equipment and the processing capability for the use equipment under the dual connectivity could be ensured.

Description

technical field [0001] Embodiments of the invention generally relate to wireless communication systems. More specifically, embodiments of the present invention relate to a method and apparatus for scheduling user equipment in a wireless communication system supporting dual connectivity. Background technique [0002] Since low-power nodes can bring gains in terms of capacity expansion and blind spot coverage, more and more research focuses on the deployment and enhancement of small cells covered by low-power nodes. Here, the low-power node may be a small base station, examples of which include but are not limited to low-power base stations such as Pico and Femto. In 3GPP R12, a new research item "Small Cell Enhancements for E-UTRA and E-UTRAN Higher-layer aspects" has been approved and One key point is to support dual connectivity to the macro cell (the cell covered by the macro base station) layer and the small cell layer. [0003] In wireless communication, different rad...
