1Multicell power allocation method based on game theory for inter-cell interference coordination显示文摘As a new technology, coordinated multipoint (CoMP) transmission is included in LTE-Advanced study item. Moreover, the network architecture in LTE-Advanced system is modified to take into account coordinated transmission. Under this background, a novel power allocation game model is established to mitigate inter-cell interference with cellular coordination. In the light of cellular cooperation relationship and centralized control in eNodeB, the power allocation in each served antenna unit aims to make signal to interference plus noise ratio (SINR) balanced among inter-cells. Through the proposed power allocation game algorithm, the users' SINR can reach the Nash equilibrium, making it feasible to reduce the co-frequency interference by decreasing the transmitted power. Numerical results show that the proposed power allocation algorithm improves the throughput both in cell-center and cell-edge. Moreover, the blocking rate in cell-edge is reduced too.ZHANG Hui XU XiaoDong LI JingYa TAO XiaoFeng ZHANG Ping SVENSSON Tommy BOTELLA Carmen 2009Science in China(Series F)2009,52,12:5
2Performance of power control in inter-cell interference coordination for frequency reuse显示文摘To mitigate inter-cell interference in 3G evolution systems,a novel inter-cell interference coordination scheme called soft fractional frequency reuse is proposed in this article,which enables to improve the data rate in cell-edge.On this basis,an inter-cell power control is presented for the inter-cell interference coordination,and the inter-cell balanced signal to interference plus noise ratio(SINR) among users is established for power allocation,which enables mitigation of inter-cell interference.Especially,the power control is based on a novel exponential kernel equation at higher convergence speed than the traditional arithmetic kernel equations.Numerical results show that the proposed scheme improves the throughput and reduces the blocking rate compared to the existing power control algorithms.ZHANG Hui XU Xiao-dong LI Jing-ya TAO Xiao-feng Tommy Svensson Carmen Botella 2010The Journal of China Universities of Posts and Telecommunications2010,17,1:2

8Multi-beam cooperative frequency reuse for coordinated multi-point transmission显示文摘Coordinated multi-point (CoMP) joint transmission is considered in the 3rd generation partnership project (3GPP) long term evolution (LTE)-advanced as a key technique to mitigate inter-cell interference and improve the cell-edge performance. To effectively apply CoMP joint transmission,efficient frequency reuse schemes need to be designed to support resource management cooperation among coordinated cells. However,most of the existing frequency reuse schemes are not suitable for CoMP systems due to not considering multi-point joint transmission scenarios in their frequency reuse rules. In addition,the restrictions of frequency resources in those schemes result in a high blocking probability. To solve the above two problems,a multi-beam cooperative frequency reuse (MBCFR) scheme is proposed in this paper,which reuses all the available frequency resources in each sector and supports multi-beam joint transmission for cell-edge users. Besides,the blocking probability is proved to be efficiently reduced. Moreover,a frequency-segment-sequence based MBCFR scheme is introduced to further reduce the inter-cell interference. System level simulations demonstrate that the proposed scheme results in higher cell-edge average throughput and cell-average throughput with lower blocking probability.LI Jing-ya XU XiaoTdong ZHANG Hui TAO Xiao-feng Tommy Svensson Carmen Botella CHEN Xin 2010The Journal of China Universities of Posts and Telecommunications2010,17,6:0
9Improved resource allocation strategy in SU-CoMP network显示文摘Coordinated multi-point transmission and reception (CoMP) for single user, named as SU-CoMP, is considered as an efficient approach to mitigate inter-cell interference in orthogonal frequency division multiple access (OFDMA) systems. Two prevalent approaches in SU-CoMP are coordinated scheduling (CS) and joint processing (JP). Although JP in SU-CoMP has been proved to achieve a great link performance improvement for the cell-edge user, efficient resource allocation (RA) on the system level is quite needed. However, so far limited work has been done considering JP, and most existing schemes achieved the improvement of cell-edge performance at cost of the cell-average performance degradation compared to the single cell RA. In this paper, a two-phase strategy is proposed for SU-CoMP networks. CS and JP are combined to improve both cell-edge and cell-average performance. Compared to the single cell RA, simulation results demonstrate that, the proposed strategy leads to both higher cell-average and cell-edge throughput.CHEN Xin XU Xiao-dong LI Hong-jia TAO Xiao-feng Tommy Svensson Carmen Botella 2011The Journal of China Universities of Posts and Telecommunications2011,18,4:0
