Resource scheduling method, device and system

Abstract

The invention discloses a resource scheduling method which comprises the steps: arranging multiple stages of filter resource pools between a CPRI / ECPRI and an antenna channel, each stage of filter resource pool comprises different types of filters, wherein the adjacent stages of filter resource pools are connected through full mapping; obtaining a carrier channel building instruction, wherein the instruction comprises carrier channel building condition parameters; selecting a matched filter from the filter resource pools of all levels according to the construction condition parameters; and combining the selected filters and the connection channels thereof based on the full mapping connection between the filter resource pools of all levels so as to complete the establishment of the corresponding carrier channels. According to the invention, each carrier channel can accurately combine the filters required by the carrier channel according to the requirements of a carrier scene; then the order of the prototype filter can be selected according to the carrier scene requirement, and the prototype filter with less order can be used for the low-rate baseband carrier, so that the order of the filter is reduced and the resource consumption is reduced; furthermore, each carrier channel accurately selects a filter resource, so that the power consumption is reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a resource scheduling method, device and system. Background technique [0002] Wireless communication devices usually need to support multiple antenna carrier standard scenarios at the same time, such as the multi-mode scenario where 5G NR (New Radio) and Long Term Evolution (LTE, Long Term Evolution) coexist. Then, it is a huge challenge for the design to flexibly support various carrier systems and optimize resources. [0003] The digital upconverter (DUC, Digital UpConverter) / digital downconverter (DDC, Digital Down Converter) unit of the remote radio unit (RRU, Remote Radio Unit) device realizes the upconversion of the downlink and the downconversion of the uplink . The baseband processing unit (BBU, Base Band Unit) performs service data interaction with the RRU through the common public radio interface (CPRI, Common Public Radio Interface) or the enh...

AI Technical Summary

Problems solved by technology

[0009]1) Since each parallel carrier processing channel in the carrier resource pool is the same, each carrier processing channel supports all carrier scenarios. , the number of filter branches of each carrier processing channel increases, and the resource consumption gradually increases

And because each carrier processing channel only satisfies one carrier standard, that is, only one path branch is selected, which causes waste of resources

[0010]2) The unselected branch in each carrier channel, that is, the module that the dotted line flows through, does not work, which increases the power consumption additionally

[0011]3) Since the parallel carrier processing channels of each channel are the same, the order of the prototype filter needs to satisfy the carrier with the maximum sampling rate of the supported scene. When the supported scene There are low-rate carrier systems and high-rate carrier systems at the same time, which will cause waste of filter orders

[0012]If each carrier processing channel is customized to support a certain carrier system, it is impossible for the device to support a variety of carrier system scenarios, and the device can expand the carrier system scene difficult to upgrade
