Abstract

The invention provides a discrete speed cross-layer power distribution method suitable for a distribution type antenna system which relates to a cross-layer power distribution method suitable for a single subdistrict distribution type antenna system among each user. In the distribution type antenna system, a suitable power is distributed to each user for completing an operation transmitting from point to point. The method obtains a queue state information of a data link layer and a channel state information of a physical layer in condition of assuming a base station only using finite discrete transmitting speed, then processes cross-layer power distribution by using a throughput a coefficient of improved particle group arithmetic optimizing system and a fairness coefficient. The discrete transmitting speed assuming is more coincided with factual system, the distribution type antenna system uses the cross-layer distribution method that can improve system queue time delay performance, system throughput performance and system fairness performance.

Description

technical field

[0001] The invention relates to an adaptive cross-layer power allocation method suitable for a distributed antenna system, which belongs to the field of wireless resource management in mobile communication. technical background

[0002] The distributed antenna system (Distributed Antennas System, DAS) disperses multiple antennas in different locations of the cell, and connects these antennas to the base station through optical fiber, cable or wireless transmission, reducing the average distance between the antenna and mobile users , can improve the coverage capability and system capacity of the system wireless signal, and thus become a new trend in the development of the public wireless interface in the future.

[0003] Power allocation is one of the essential resource management techniques in distributed antenna systems, which directly affects the overall performance of the system. At present, the research on power allocation mainly focuses on centralized s...
