Embodiment

[0043] Embodiment: This embodiment takes a two-layer heterogeneous network as an example. The schematic diagram of the two-layer heterogeneous network structure is as follows figure 2Shown: There are 21 Macro base stations in the heterogeneous heterogeneous network, which are represented by numbers 1 to 21, among which 5 Pico base stations are randomly distributed in each of the 7 Macro base stations, and the remaining 14 Macro base stations do not include Pico base stations . 10 users are randomly distributed in each base station. The Macro base station and the Pico base station work on a 2GHz carrier and have a bandwidth of 10MHz. The transmit power of the Macro base station and the Pico base station are 46dBm and 30dBm respectively. In this embodiment, the receiving model only considers path loss and shadow fading and does not consider fast fading.

[0044] The introduction of Pico base stations is to divert some users for Macro base stations. Now the coverage of Macro b...

Abstract

The present invention proposes a network resource allocation method under a heterogeneous network with a two-layer non-uniform topological structure. The target model is constructed as the logarithmic sum of all user rates and the problem to be solved by the target model is divided into three sub-problems to be solved in turn: First, initialize other parameters to solve the current user connection and frequency resource allocation; second, when the user connection and frequency resource allocation are determined, solve the current optimal ABS ratio configuration; third, solve each Macro base station The transmit power in the ABS time slot; set the termination condition, execute step 1 to step 3 in a loop, and stop the loop when the termination condition is satisfied. This method can increase the total user rate of the system and guarantee the fairness among users.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for allocating network resources in a heterogeneous network with a two-layer heterogeneous topology. The method ensures user fairness in the access layer of a heterogeneous network with a heterogeneous topology. Under the condition of maximizing the total throughput of the system, the power and resource allocation of the system are completed. Background technique [0002] Nowadays, with the rapid development of mobile communication, the popularization of mobile smart terminals and the wide application of various real-time media services, the traffic in broadband wireless networks is increasing at an exponential rate, so the demand for higher coverage and faster data rate services is also stronger. Since spectrum resources are limited, an effective method is to increase spectrum utilization. LTE-Advanced proposes some base stations with smaller sizes. Such base station...
