Method and device for allocating resources for wireless terminal directly connected user

Abstract

The embodiment of the invention discloses a method and a device for allocating resources for a wireless terminal directly connected user (D2D). The method comprises the following steps of: formulatinga reinforcement learning (RL) algorithm according to the uncertainty of a wireless channel state and a state transition possibility. Each pair of D2D users can be viewed as an independent agent, making decisions based on the channel state it observes locally. In order to solve the problem of sequential decision-making in multi-user systems, a multi-agent RL algorithm is proposed. We assume that D2D users do not have any information about the availability and quality of the resource blocks to be allocated, so the problem is modeled as a stochastic non-cooperative game. Therefore, each agent becomes a participant in the non-cooperative game, and all participants make decisions together in order to achieve the optimization of all benefits. The embodiment of the invention can lighten the loadand improve the capacity of the cellular network, and the system throughput can be maximized through effective energy management.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for supporting communication resource allocation in a wireless terminal direct communication (D2D) system. Background technique [0002] At the current stage, with the rapid popularization of smart terminals and the explosive growth of network communication capacity, the evolution requirements for 5G-oriented wireless communication technologies are becoming clearer and more urgent. In the evolution of 5G-oriented wireless communication technology, on the one hand, traditional wireless communication performance indicators, such as network capacity and spectrum efficiency, need to be continuously improved to further improve the limited and increasingly tense wireless spectrum utilization; on the other hand, more abundant The communication mode and the resulting improvement of end user experience and the expansion of cellular communication ...

Problems solved by technology

When the orthogonal mode is used for communication, the idle RB (Resource Block, resource block) of the cell is occupied to transmit signals, which will not cause interference, but when the D2D user uses the multiplexing mode for communication, the same RB transmission is occupied by the cellular user. Signals will cause serious interference, so how to reasonably allocate resources for D2D users to reduce interference has become a key issue in D2D communication technology
