摘要

提出一种全新通信服务体制——虚拟实时服务，可有效发掘和利用负时间轴上蕴含的大量空闲时、频资源，并利用预先推送较大的时延容忍，人为制造业务趋同性，获取无线多播带来的巨大能效和谱效增益。介绍了虚拟实时服务在认知对象、时间尺度、协同范围3个层面的拓展，阐明其能效和谱效增益的代价是计算和存储资源的消耗，从而需要通过计算（含认知）、存储和通信单元的多元协同，以最少计算和存储资源，换取能效和谱效的最大提升。虚拟实时服务有望突破现有通信体制及其理论基础对于资源效率的内在束缚。其两大特质——“非时齐”和“多元协同”的结合，有望形成一种创新的非时齐多元协同通信理论。

Abstract

A novel communication service methodology

virtual real-time service

was proposed to discover and utilize the rich temporal and spectrum resource hidden in the negative time axis. Thanks to the delay tolerance of embedded wireless pushing

it could help to unify the content demand of different users

so as to achieve significant spectral and energy efficiency gains of wireless multicasting. The three extensions of cognition object

time scale

and coordination range

induced by virtual real-time service were described. The consumption of computation and storage resource was a cost to be paid for the gains of the energy and spectral efficiency.Hence

the multi-unit collaboration of computation （including cognition）

storage

and communications units was highly desired to minimize the cost of computation and storage resource

while maximize the energy and spectral efficiency gains. The proposed scheme holds the promise of overcoming the stringent restrain on the spectral efficiency

which is caused by the current communication architecture and its underlying theory. The union of its two main characteristics

namely

time non-homogenous transmission and multi-unit collaboration

are expected to form a paradigm-shift theory on time non-homogenous multi-unit collaboration communications.
