【摘要】:針對異構(gòu)網(wǎng)絡(luò)中毫微微小區(qū)(femtocell)之間的同層干擾和femtocell與宏小區(qū)(macrocell)之間的跨層干擾,提出一種基于分簇的資源管理方案。該方案包括兩部分:第1部分是宏基站(macrocell base station,MBS)利用三輪子信道分配算法為宏用戶分配子信道,再采用注水算法分配功率;第2部分首先采用遺傳模擬退火算法為femtocell分簇,再利用啟發(fā)式算法和卡羅需-庫恩-塔克(Karush-Kuhn-Tucker,KKT)條件為毫微微用戶分別分配子信道和功率。仿真結(jié)果表明,該方案有效地抑制了網(wǎng)絡(luò)中的這兩種干擾,滿足了用戶的數(shù)據(jù)速率需求,有效地提高了頻譜效率。
[Abstract]:Aiming at the same layer interference between (femtocell) and (macrocell) in heterogeneous networks, a resource management scheme based on clustering is proposed. The scheme consists of two parts: the first part is the macro base station (macrocell base station,MBS) uses the three-wheel channel allocation algorithm to allocate the subchannel to the macro user, and then uses the water injection algorithm to allocate the power; in the second part, the genetic simulated annealing algorithm is used to cluster the femtocell, and then the heuristic algorithm and Carol Kuhn-Tucker (Karush-Kuhn-Tucker,KKT) condition are used to allocate the subchannel and power respectively. The simulation results show that the scheme effectively suppresses these two kinds of interference in the network, meets the data rate requirements of users, and effectively improves the spectral efficiency.
