Dispatching configuring method and device

Abstract

The invention discloses a dispatching configuring method. The dispatching configuring method comprises the steps that a centralized control unit configures coordination parameters of different nodes; and distributive dispatching units in the nodes dispatch user resources of the corresponding nodes. The invention further discloses a dispatching configuring device composed of a configuring unit and the dispatching units. The configuring unit is arranged in the centralized control unit and used for configuring the coordination parameters of the different nodes. The dispatching units are arranged in the modes and used for dispatching the user resources in the corresponding nodes. By means of the technical scheme, the non-coordination user time delay problem caused by backhaul transmission under the centralized dispatching mode is solved. Coordinative configuration is carried out on the relative half-static or slow changing parameters, and under the situation that system transmission is achieved, the user dispatching flexibility is not affected.

Description

technical field [0001] The invention relates to scheduling technology, in particular to a scheduling configuration method and device. Background technique [0002] In Long Term Evolution System Version 11 (LTE R11, Long Term Evolution Release 11), in order to support Coordinated Multipoint Transmission and Reception (COMP, Coordinated Multipoint Transmission and Reception), the concept of CSI process (CSI-process) is introduced: each CSI The process corresponds to a channel state information reference signal (CSI-RS, Channel State Information Reference Signal) resource and a channel state information interference measurement resource (CSI-IMR, Channel State Information–Interference Measurement Resource); among them, the transmission mode supporting COMP is TM10. [0003] The CSI-RS resource is defined in TS36.211-b30. When the system supports a maximum of 8 antenna ports, the CSI-RS is at the antenna port p=15, p=15,16, p=15,...,18 , transmitted on p=15,...,22. According ...

Problems solved by technology

In the case of centralized scheduling, each node reports the CSI and other information of the users in this cell to the central scheduler. After the central scheduler performs scheduling, it configures the scheduling results to different nodes. However, in this way, when nodes When there is a delay in interaction, it will increase the scheduling delay of non-COMP users, thus affecting the performance of non-COMP users

In the case of distributed scheduling, although independent scheduling between nodes can avoid scheduling delays, due to the need for information such as CSI and resource mapping methods between interfaces, and due to ZP CSI-RS cooperative configuration, the BF weight and resource Collaborative mutual reference problem will lead to complex interaction between nodes and difficult collaboration
