Problems solved by technology

However, if eNB1 and eNB2 use the unlicensed frequency band F3 for data transmission at the same time, since the base station of OP1 and the base station of OP2 have not carried out good cell planning, eNB1 and eNB2 will have relatively serious mutual interference on the unlicensed frequency band F3, resulting in Transmission performance degrades on unlicensed bands and may even be unusable
[0005] Therefore, if multiple operators deploy independent LTE systems in the same geographical area and use the same unlicensed frequency band resources, there may be mutual interference among the multiple LTE systems, which affects the transmission performance on the unlicensed frequency band
[0006] At present, there is no effective solution to the problem of interference between systems using the same unlicensed frequency band due to the lack of planning for the use of unlicensed frequency bands

Embodiment 1

[0132] There are shared nodes and network nodes of multiple operators in the network, and an ideal backhaul link exists between the shared nodes and the network nodes. Such as Figure 5 As shown, when a network node is about to transmit data, it can notify the shared node of the amount of service data (including service type and service QoS information) through the ideal backhaul link; the shared node receives data from multiple network nodes business information, and determine the resources that can be used to transmit at least one network node data according to the received business information, and then notify the corresponding network node of the resource information; the network node determines the business data transmitted on the shared node according to the resource information , and then schedule the shared node to transmit the service data, and transmit the service data to the shared node; the shared node transmits the service data on the scheduled resource.

Embodiment 2

[0134] There are shared nodes and network nodes of multiple operators in the network, and an ideal backhaul link exists between the shared nodes and the network nodes. Such as Figure 6 As shown in , when a network node is about to transmit data, it can notify the shared node of the amount of service data (including service type and service QoS information) through an ideal link link; the shared node receives information from multiple networks According to the business information of the node, the resource that can be used to transmit at least one network node data is determined according to the received business information, and the resource information is notified to the corresponding network node; the network node determines the business data transmitted in the shared node according to the resource information and Scheduling information, and transmit service data and scheduling information to shared nodes; shared nodes receive service data and scheduling information transmi...

Embodiment 3

[0136] There are shared nodes and network nodes of multiple operators in the network, and non-ideal backhaul links exist between the shared nodes and the network nodes. Such as Figure 7 As shown, when a network node is about to transmit data, it can notify the shared node of the amount of service data (including service type and service QoS information) through a non-ideal link; the shared node receives information from multiple networks According to the business information of the node, the resource that can be used to transmit at least one network node data is determined according to the received business information, and the resource information is notified to the corresponding network node; the network node determines the business data transmitted in the shared node according to the resource information, And transmit the service data to the shared node; the shared node receives the service data transmitted by the network node, schedules and transmits the service data on t...

Abstract

The invention discloses a method and device for realizing a shared node and a network node. The method for realizing the shared node includes: the shared node receives business information from the plurality of network nodes, wherein the shared node There is a connection with multiple network nodes; the shared node determines the resources that can be used to transmit the service data of at least one of the multiple network nodes on a frequency band based on the service information of the multiple network nodes. ; The shared node transmits the service data of the at least one network node in the resource. The present invention determines the resources that can be used by some or all network nodes according to the business information of multiple network nodes, thereby avoiding interference between multiple network nodes and effectively solving the problem that multiple systems are prone to interference with each other when using unlicensed spectrum. problem, improve system performance, and optimize the use of frequency band resources.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to a method and device for implementing a shared node and a network node. Background technique [0002] With the continuous growth of mobile data traffic, spectrum resources are becoming more and more tight. Only using licensed spectrum resources for network deployment and service transmission may not be able to meet the traffic demand. Therefore, consider using unlicensed spectrum in LTErel-13 or subsequent versions To improve user experience and extend coverage. [0003] Existing spectrum resources can be divided into licensed spectrum and unlicensed spectrum. Among them, the licensed spectrum is a dedicated dedicated spectrum. Long Term Evolution (LTE) operators have dedicated licensed frequency bands. Different operators have different licensed frequency bands. There will be no interference from other LTE operators. interference. On the other hand, unlicensed spectrum i...
