Abstract

The present invention proposes a method and a network system for resource allocation in a direct-device connection communication network. The resource allocation method includes the following steps: system initialization, establishing an objective function and a constraint relationship; solving the objective function, and obtaining a device direct-connection user transmission Power, sub-channel allocation strategy, and total energy efficiency of the direct-to-device network; judge whether the current number of iterations is greater than the maximum number of iterations, and if so, output the optimal transmission power of direct-to-device users, the optimal sub-channel allocation strategy, and the optimal total network energy efficiency, otherwise go to the next iteration. The present invention considers the channel uncertainty, and can well limit the interference power to the cellular users and protect the cellular user network by controlling the optimal transmission power, the optimal subchannel allocation strategy, and the optimal total energy efficiency of the device direct-connection network for the device direct-connection users Excellent service quality, with good tenacity.

Description

technical field [0001] The present invention relates to the technical field of wireless network resource allocation, in particular to a method and network system for allocating robust resources in a device directly connected communication network, in particular to a method and network for allocating robust resources based on the worst criterion in a device directly connected wireless network system. Background technique [0002] Device-to-Device (D2D) communication technology has become a new distributed and cooperative communication method by reusing the spectrum resources of cellular users. The communication technology can allow terminal equipment to realize communication by means of direct connection between terminals without basic network facilities. It is a new technology that effectively improves spectrum efficiency and reduces network burden. [0003] Cognitive Radio (CR) technology can dynamically monitor spectrum utilization, and opportunistically access the primar...
