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 the ZP CSI-RS cooperative configuration, the BF weight and resource Collaborative mutual reference problem will lead to complex interaction between nodes and difficult collaboration

Abstract

The invention discloses a scheduling configuration method, which includes: a centralized control unit configures cooperative parameters of different nodes, and a distributed scheduling unit in each node schedules user resources of the node. The invention also discloses a scheduling configuration device, a configuration unit and a scheduling unit, wherein: the configuration unit is set in the centralized control unit and is used to configure the coordination parameters of different nodes; the scheduling unit is set in each node and uses It is used to schedule the user resources of this node. Adopting the technical solution of the present invention overcomes the time delay problem of non-cooperative users caused by backhaul transmission under the centralized scheduling mode; through cooperative configuration of relatively semi-static or slow-changing parameters, in the case of system transmission , does not affect the scheduling flexibility for users.

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 MeasurementResource); 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 ...
