摘要
Abstract
To achieve the core goal of ubiquitous connectivity in 6G,low Earth orbit(LEO)satellites,with their advantages of low latency and global coverage,have become the focus of mobile satellite communications.However,as the communication capacity provided by a single satellite is gradually approaching its limits due to industrial manufacturing constraints,collaborative air-interface wireless transmission aggregating resources from multiple LEO satellites has become an important research direction.This paper systematically reviews the key characteristics and emerging requirements of channel state information acquisition and uplink/downlink spatial transmission in the multi-satellite collaborative scenario,and introduces collaborative resource allocation strategies based on these findings.Furthermore,an architecture for deployment based on inter-satellite dual connectivity and intra-satellite carrier aggregation is explored.Finally,the challenges and future prospects of multi-satellite collaboration are discussed,providing a reference for the development of satellite networks in the 6G era.关键词
