Abstract

The embodiment of the present application discloses a coordinated scheduling method and device, which relate to the communication field and can reduce the interference between macro cell users and micro cell users. The specific solution is: the first node receives the coordination scheduling request sent by the second node; according to the first weak subframe pattern, the first weak subframe uses a lower power than the normal subframe to transmit the downlink data channel of the first user or a lower power than the normal subframe The service grant SG with a lower subframe schedules the uplink data channel of the first user; wherein the first user includes users in the first node cell that cause interference to the second node cell and / or soft handover zone users. This application is used to coordinate the scheduling process.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method and device for coordinated scheduling. Background technique [0002] The wireless communication field is facing the pressure of explosive growth of data services. In order to increase network capacity and reduce transmission costs, a heterogeneous network (Heterogeneous Network, Hetnet) technology has been proposed in the industry. The Hetnet consists of multiple cells of different sizes and types, including macro cells (Macro cells) and micro cells. The micro cell includes: a micro cell (Micro cell), a pico cell (Pico Cell), a femto cell (Femto Cell), a cell in the form of a remote radio head (Remote Radio Head, RRH), etc. By deploying more microcells in traffic-intensive areas, the network capacity of the area can be effectively increased, and the construction cost (Capital Expenditure, Capax) and operating cost (Operating Expense, Opex) of microcells are both ...
