AI Technical Summary

Technical Problem

Existing wireless communication systems struggle to efficiently transmit ultra-high-speed signaling field information when providing ultra-high-speed wireless LAN services, impacting resource utilization and system performance.

Method used

By introducing PPDUs with extremely high throughput (EHT) signal (SIG) content channels into wireless communication systems, resource element (RU) allocation subfields are encoded/decoded using common fields and user-specific fields respectively, thereby identifying and configuring the packet structure of the PPDU.

Benefits of technology

It improves signaling transmission efficiency, increases resource utilization in contention-based access systems, and enhances the performance of wireless LAN systems.

Abstract

本发明涉及在无线通信系统中发送和接收数据的方法和终端。公开了一种在无线通信系统中接收物理层协议数据单元（PPDU）的方法。终端从接入点（AP）接收包括至少一个极高吞吐量（EHT）‑信号（SIG）内容信道的EHT PPDU。上述至少一个EHT‑SIG内容信道中的每一个包括包含至少一个第一资源单元（RU）分配子字段的公共字段和用户特定字段。然后，STA可以识别公共字段是否还包括至少一个第二RU分配子字段，并且可以基于公共字段是否还包括至少一个第二RU分配子字段来解码PPDU。
