(EN) Method for transmitting PPDU and related device
(ZH) 传输PPDU的方法及相关装置
Abrégé
(EN) The invention relates to the field of wireless communication, in particular to a method for transmitting a physical layer protocol data unit and a related device, for example, the method and the related device are applied to a wireless local area network supporting an 802.11 be standard. The method comprises: a first communication device generating a PPDU, and sending the PPDU by using a first bandwidth, the first bandwidth being greater than or equal to 80MHz; correspondingly, a second communication device receives and analyzes the PPDU to collect an LTF sequence included in the PPDU; the LTF sequence is generated based on a first LTF sequence, which is not a high efficiency LTF sequence. By adopting the embodiment of the invention, the LTF sequence suitable for channel estimation can be designed for a larger bandwidth, and a basis is provided for subsequent channel estimation.
(ZH) 本申请涉及无线通信领域,尤其涉及一种传输物理层协议数据单元的方法及相关装置,比如应用于支持802.11be标准的无线局域网中。该方法包括:第一通信设备生成PPDU,并可以采用第一带宽发送该PPDU,该第一带宽大于或等于80MHz;相应地,第二通信设备接收并对该PPDU,进行解析,得到该PPDU中包括的LTF序列;该LTF序列基于第一LTF序列生成,该第一LTF序列不是高效率LTF序列。采用本申请实施例,能够针对更大带宽,设计适用于信道估计的LTF序列,为后续的信道估计提供基础。
