Abstract

Sidelink relays are critical for enabling multi-hop peer-to-peer communications and ensuring connectivity of 6G sidelink mesh networks. To find proper sidelink relays without centralized coordination, a scheme of distributed relay discovery and selection named SideSeeker is designed with two key mechanisms. First, a two-dimensional contention scheme in time and frequency dimensions is designed based on short-term sensing, such that the collision of control signals is alleviated. Second, a mechanism of source-relay pair selection is developed, which prevents data congestion at a certain relay. With SideSeeker, the throughput over sidelinks outperforms those of baseline schemes by 19.4 – 36.9%.

SideSeeker：边链路网状网络基于竞争的分布式中继搜索

侧链中继对于实现多跳点对点通信和确保 6G 侧链网状网络的连接性至关重要。为了在没有集中协调的情况下找到合适的侧链路中继器，设计了一种名为 SideSeeker 的分布式中继器发现和选择方案，其中包含两个关键机制。首先，设计了一种基于短期感应的时间和频率维度的二维争用方案，从而缓解了控制信号的碰撞。其次，开发了一种源-中继配对选择机制，可防止某个中继站出现数据拥塞。采用 SideSeeker 后，通过侧向链路的吞吐量比基准方案高出 19.4 - 36.9%。
