【摘要】:將信干噪比估計(jì)不確定問(wèn)題引入到有幾乎空白子幀存在時(shí)的異構(gòu)網(wǎng)絡(luò)中,在異構(gòu)網(wǎng)絡(luò)中提出一種新的用戶選擇接入和資源分配聯(lián)合算法。為了用最少的無(wú)線資源滿足用戶的傳輸速率需求,將問(wèn)題建模為最小-最大差值廣義分配模型,然后進(jìn)行求解。仿真結(jié)果驗(yàn)證了本文方法的可行性。
[Abstract]:The signal-to-noise ratio (SINR) estimation uncertainty problem is introduced into heterogeneous networks with almost blank subframes, and a new joint algorithm of user selection access and resource allocation is proposed in heterogeneous networks. In order to satisfy the transmission rate requirements of users with the least wireless resources, the problem is modeled as a minimum-maximum difference generalized allocation model, and then solved. The simulation results verify the feasibility of this method.
