Concrete scene example is as follows:
Target environment is visible ray and LTE isomery UNEs, is 5 × 9m in floor space2Three layers of office building in, institute There is region by a networks (visible ray) and b networks (LTE) while cover, heterogeneous network access point set is M={ 1,2,3,4 ... M }, user's collection is combined into N={ 1,2,3,4 ... N }.Wherein LTE network has an access point, and VLAN has three access points, each Access point enjoys 10MHz bandwidth resources.LTE network shares 3MHz bandwidth, and vlan network shares 30MHz bandwidth.LTE network For ofdm system, VLAN is OFDM systems.The set of sub-channels of LTE network is combined into L={ 1,2,3......L }, per sub-channels With a width of B0.Each user can only select a network.
Wherein,User i selection a networks are represented, User i selection b networks are then represented,In order to avoid causing the cochannel in cell to disturb, each frequency resource block is at most assigned to only a user.
In the lte networks, a user, i.e. s can only be distributed to per sub-channelsi,l=1 represents in user i selection b nets L-th of channel, si,l∈{0,1}。The transmit power on l channels in user i selection b nets is represented,Represent user i in a nets In bandwidth,Represent channel gains of the user i in b nets on down channel l.Represent user i descending chains in network a The transmission power on road,Represent channel gains of the user i in a nets on down channel.For a network downstream interchannel noise work( Rate spectrum density, N0For b network downstream channel noise power spectrum densities.
So, in a networks user i transmission rate
