Problems solved by technology

While pursuing the overall data rate performance of the system, they ignore the differences in the QoS requirements of different users on the entire network, so the individual minimum performance level of the scheduled transmission cannot be guaranteed, and may suffer from communication interruption
Furthermore, these schemes do not consider power control and interference control

Abstract

The invention discloses a distributed method for dynamic access point selection in a wireless network. through a distributed power calculation method based on a power updating factor, greedy access point selection is realized, and thus, only a small part of power updating factors needs to be exchanged among receivers, the remaining power updating factors can be obtained through automatic derivation based on local information, global optimization on pairing between a receiver and a transmitter, access point selection and power control becomes simpler, and thus, the computational cost and the signaling overhead are significantly reduced.

Description

technical field [0001] The invention relates to the field of wireless communication, more specifically to a distributed method for dynamic access point selection in a wireless network. Background technique [0002] The ultra-dense network (Ultra-Dense Network, UDN) technology with the ability to reuse all frequency bands is one of the most promising 5G candidate technologies. While the concept of cell segmentation / small cells is not new, Ultra-Dense Networks hopes to move beyond the mere concept of cellular data offloading by rethinking the design of current wireless networks. In order to meet the exponential increase in the number of user equipment (UE) and single-user rate requirements, dozens or even hundreds of low-power access nodes (APs) (such as small cells, distributed antenna, etc.) or peer-to-peer (such as direct (Device-to-Device, D2D)) communication between devices. Figure 6 A schematic diagram of an ultra-dense network is shown. As shown in the figure, in an ...
