Description
技术领域 technical field
本发明涉及一种无线通信技术领域的方法，具体是一种协作通信中协作用户QoE的改善方法。The invention relates to a method in the technical field of wireless communication, in particular to a method for improving QoE of cooperative users in cooperative communication.
背景技术 Background technique
随着当今无线通信业务的迅速发展，无线网络的用户对高速率和高性能的语音、数据以及多媒体服务的需求量越来越大。因此，下一代无线通信系统，例如B3G/4G，将会采用先进的算法和技术来提高数据传输速率和系统性能。无线通信信道的多径衰落特性是限制传输速率和系统性能的主要原因之一，而分集技术是有效对抗无线通信信道多径衰落的关键技术。由于能提供显著的空间分集增益，多天线(MIMO)技术已被确定为IEEE802.16系统、WiMAX无线局域网系统以及3GPP LTE(3GPP长期演进型)组织定义的超三代(S3G)蜂窝移动通信系统的下行传输技术，也有希望应用于B3G/4G的下行系统中。但是在无线通信的上行传输系统中，由于受到移动终端的尺寸限制，多天线技术难以实现，而极有可能取而代之的是目前备受关注的协作通信技术。该技术利用小区内分散的用户天线协作传输相同的信息，从而能获得与多天线技术相似的空间分集效果。由于有希望成为B3G/4G的上行传输方案，协作通信吸引了众多有志于研究下一代无线通信的专家和学者。他们用系统建模、理论推导和性能验证等方法产生了大量关于协作通信的研究成果，这些研究成果大多通过论文的方式展现。许多最新的研究进展，可以从美国电气电子工程师学会(IEEE)的期刊杂志中检索得到。With the rapid development of today's wireless communication services, users of wireless networks have an increasing demand for high-speed and high-performance voice, data and multimedia services. Therefore, next-generation wireless communication systems, such as B3G/4G, will use advanced algorithms and techniques to improve data transmission rates and system performance. The multipath fading characteristic of wireless communication channels is one of the main reasons that limit the transmission rate and system performance, and diversity technology is the key technology to effectively combat multipath fading of wireless communication channels. Because it can provide significant space diversity gain, multi-antenna (MIMO) technology has been identified as IEEE802.16 system, WiMAX wireless local area network system and 3GPP LTE (3GPP Long Term Evolution) organization defined super three-generation (S3G) cellular mobile communication system. The downlink transmission technology is also expected to be applied to the B3G/4G downlink system. However, in the uplink transmission system of wireless communication, due to the limitation of the size of the mobile terminal, the multi-antenna technology is difficult to implement, and it is very likely to be replaced by the cooperative communication technology that is currently attracting attention. This technology utilizes distributed user antennas in the cell to cooperate to transmit the same information, so as to obtain a space diversity effect similar to that of the multi-antenna technology. Since it is expected to become the uplink transmission scheme of B3G/4G, cooperative communication has attracted many experts and scholars who are interested in researching the next generation of wireless communication. They used methods such as system modeling, theoretical derivation, and performance verification to produce a large number of research results on collaborative communication, and most of these research results are presented in the form of papers. Many of the latest research progress can be retrieved from journals of the Institute of Electrical and Electronics Engineers (IEEE).
经对现有技术的文献检索发现，Jianghong Luo等在《IEEE CommunicationLetters》(IEEE通信技术通讯稿)上发表的“Power Allocation in a TransmitDiversity System with Mean Channel Gain Information”(传输分集系统中采用平均信道增益的功率分配方法)，该文中提出门限平均功率分配方法，具体方法为：给候选协作节点的信道质量设定门限值，并由源节点将总发送功率平均分配给信道质量高于门限的候选协作节点。其不足在于：忽略了协作用户的QoE(体验质量)的恶化问题。在协作通信中，协作用户通过损耗自身的电池电量和寿命，帮助源用户转发数据，从而为源用户提供空间分集。所以，源用户的通信性能和体验质量的提升是以协作用户体验质量的恶化为代价的。只要信道状况足够好，任何用户都可以被选为协作用户。这就使得那些持续拥有良好信道状况的用户，将会成为持续协作用户，不断地损耗自己的电池。因此，有必要设立一种对协作用户所作贡献的评估和补偿机制，以改善协作用户的QoE。Through literature retrieval of prior art, it is found that "Power Allocation in a TransmitDiversity System with Mean Channel Gain Information" published by Jianghong Luo et al. in "IEEE Communication Letters" (IEEE communication technology newsletter) In this paper, a threshold average power allocation method is proposed. The specific method is: set a threshold value for the channel quality of candidate cooperative nodes, and the source node distributes the total transmission power evenly to the candidate nodes whose channel quality is higher than the threshold Collaboration node. Its shortcoming is that it ignores the deterioration of QoE (Quality of Experience) of collaborative users. In cooperative communication, cooperative users help source users forward data by depleting their own battery power and life, thereby providing space diversity for source users. Therefore, the improvement of communication performance and quality of experience of the source user is at the expense of deterioration of the quality of experience of the collaborative user. As long as the channel conditions are good enough, any user can be selected as a collaborative user. This makes those users who continue to have good channel conditions will become continuous collaborative users, constantly depleting their own batteries. Therefore, it is necessary to establish an evaluation and compensation mechanism for the contributions made by collaborative users to improve the QoE of collaborative users.

具体实施方式 Detailed ways
下面结合附图对本发明的实施例作详细说明：本实施例在以本发明技术方案为前提下进行实施，给出了详细的实施方式和具体的操作过程，但本发明的保护范围不限于下述的实施例。The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings: this embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following the described embodiment.
(1)协作用户计算自己的当次协作贡献度(1) Collaborative users calculate their current collaboration contribution
本发明将协作用户的当次协作贡献度定义为：评估协作用户在某次协作通信过程中以损耗自身电池为代价对协作通信做出贡献的指标。本发明将当次协作贡献度设定为一个无量纲的量，其数值等于协作用户在某次协作通信过程中的电量消耗值(以mA计)。在某次协作通信开始的时刻，协作用户读取自己的当前电量数值(以mA计)；在该次协作通信结束的时刻，协作用户再次读取自己的当前电量数值(以mA计)。通过对这两个数值求差，该协作用户计算得到当次协作贡献度。In the present invention, the collaboration contribution degree of the collaboration user is defined as an index for evaluating the contribution of the collaboration user to the collaboration communication at the cost of depleting its own battery in a certain collaboration communication process. In the present invention, the current cooperation contribution degree is set as a dimensionless quantity, and its value is equal to the power consumption value (in mA) of the cooperative user in a certain cooperative communication process. At the beginning of a cooperative communication, the cooperating user reads its current power value (in mA); at the end of the cooperative communication, the cooperating user reads its current power value (in mA) again. By calculating the difference between these two values, the collaborative user calculates the current collaboration contribution.
(2)协作用户计算自己的当日协作贡献度(2) Collaborative users calculate their collaboration contribution for the day
本发明将协作用户的当日协作贡献度定义为：评估协作用户在某天内以损耗自身电池为代价对协作通信做出贡献的指标。本发明将当日协作贡献度设定为一个无量纲的量，其数值等于协作用户在某天内的所有当次协作贡献度的累加值。在次日第一次开机时，用户计算昨日的当日协作贡献度，并将该数值上传到运营商的网络管理节点，如图1所示。The present invention defines the collaboration contribution degree of the collaboration user on the day as an index for evaluating the contribution of the collaboration user to the collaboration communication at the cost of depleting its own battery within a certain day. In the present invention, the collaborative contribution degree of the day is set as a dimensionless quantity, and its value is equal to the cumulative value of all collaboration contribution degrees of the cooperating user in a certain day. When turning on the device for the first time the next day, the user calculates yesterday's collaboration contribution of the day and uploads the value to the operator's network management node, as shown in Figure 1.
(3)运营商更新用户的历史协作贡献度(3) The operator updates the user's historical collaboration contribution
运营商的网络管理节点在收到用户的当日协作贡献度之后，将该值累加到该用户的历史协作贡献度中，如图1所示。本发明将用户的历史协作贡献度定义为：评估用户在某天之前的时间里以损耗自身电池为代价对协作通信做出贡献的指标。本发明将历史协作贡献度设定为一个无量纲的量，其数值等于某用户在某天之前的时间里所有当日协作贡献度的累加值。After the operator's network management node receives the user's collaboration contribution of the day, it adds the value to the user's historical collaboration contribution, as shown in Figure 1 . In the present invention, the user's historical collaboration contribution is defined as an indicator for evaluating the user's contribution to collaborative communication at the cost of depleting his own battery in a certain day before. In the present invention, the historical collaboration contribution is set as a dimensionless quantity, and its value is equal to the accumulated value of all collaboration contributions of a user in a certain day before.
(4)运营商以历史协作贡献度为依据对协作用户进行补偿(4) Operators compensate collaborative users based on historical collaboration contribution
运营商根据用户的历史协作贡献度，对协作用户进行补偿，从而改善了协作用户的体验质量，如图1所示。补偿的形式可以是减免话费、赠送积分、赠送礼品等。用户的历史协作贡献度越大，则相应的补偿量也越大。本发明能改善协作通信中协作用户的体验质量，适用于B3G/4G通信系统。The operator compensates the collaborative user according to the user's historical collaboration contribution, thus improving the user's quality of experience, as shown in Figure 1. Compensation can be in the form of reduction or exemption of telephone charges, bonus points, gifts, etc. The greater the user's historical collaboration contribution, the greater the corresponding compensation. The invention can improve the experience quality of cooperative users in cooperative communication, and is suitable for B3G/4G communication systems.
