Embodiment Construction

[0032] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0033] First, a brief introduction to the nouns involved in the embodiments of this application:

[0034] A heterogeneous network is a network composed of two or more different networks. Two or more different networks use different wireless technologies. The networks are independent of each other and do not perform information exchange or resource coordination. In one example, heterogeneous networks include wireless cellular networks such as LTE and wireless ad hoc networks. Wireless ad hoc network is a temporary autonomous network including multiple communication nodes. The nodes in the network are all equal, and each communication node is equipped with a wireless transceiver, which has the functions of sending, forwarding and ...

Abstract

The invention relates to a frequency domain resource division method and device, and relates to the technical field of communication. The method comprises the following steps: determining a first preset working frequency band corresponding to a first network; determining a second preset working frequency band corresponding to the second network; and dividing the first frequency domain resource and the second frequency domain resource based on the frequency domain difference between the first preset working frequency band and the second preset working frequency band. According to the invention, preset working frequency bands corresponding to a first network and a second network respectively are determined; and on the basis of determining the difference between the first network and the second network in the working frequency domain, the different resources are allocated for downlink data transmission of the first network and data transmission of the second network. According to different conditions of the two networks, frequency domain resource allocation is coordinated; so that the common-channel interference is avoided or reduced, the network transmission performance is improved, and the service experience is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for dividing frequency domain resources. Background technique [0002] In today's Internet technology, heterogeneous network technology provides users with network access methods anytime and anywhere. A heterogeneous network is a network composed of two or more different networks. Two or more different networks use different wireless technologies. The networks are independent of each other and do not perform information exchange or resource coordination. [0003] In related technologies, a heterogeneous network is composed of a wireless cellular network such as a long term evolution network (Long Term Evolution, LTE) and a wireless ad hoc network. The wireless cellular network includes two modes: Time Division Duplexing (TDD) and Frequency Division Duplexing (FDD). The uplink and downlink transmissions between cellular base stations and...
