Problems solved by technology
[0004] However, for one of the user terminals, the subcarrier resources available to the user are reduced. For example, in the single-user mode, the user terminal can use 8 pilot subcarriers, while in the OFDMA mode, the user terminal can use 8 pilot subcarriers. There are only two pilot subcarriers used, although both can meet the resource requirements of the user terminal, but when performing channel parameter estimation, channel parameter estimation is performed based on two pilot subcarriers in the prior art, and the estimated parameters The reliability is low, resulting in a large error in the data received by the user

The embodiment of the invention provides a channel parameter estimation method and device, electronic equipment and a readable storage medium, and relates to the technical field of wireless communication. The method comprises the following steps: receiving a first pilot subcarrier allocated by a base station based on a communication protocol by a method independent related content, and acquiring allocation information of all pilot subcarriers; acquiring a second pilot frequency subcarrier except the first pilot frequency subcarrier in all pilot frequency subcarriers according to the distribution information; pilot signals carried by all pilot subcarriers are determined; and performing channel parameter estimation according to the pilot signals carried by all the pilot subcarriers to obtain a channel parameter estimation result. According to the embodiment of the invention, not only is the change of the pilot signal borne by the pilot subcarrier received by the terminal considered, but also the change of the pilot subcarrier borne by other terminals is considered, so that the reliability of a signal parameter estimation result is improved, and the error of the pilot signal received by the terminal is reduced.
Description
technical field [0001] The present application relates to the technical field of wireless communication, and in particular, the present application relates to a channel parameter estimation method, device, electronic equipment and readable storage medium. Background technique [0002] At present, in the field of wireless communication, Wi-Fi 6 (sixth generation wireless network communication technology) has been developed and used. Wi-Fi 6 mainly uses technologies such as OFDMA and MU-MIMO. OFDMA (Orthogonal Frequency Division Multiple Access, Orthogonal Frequency Division Multiple Access) Access) can allocate different subcarrier resources to multiple clients at the same time, MU-MIMO (Multi-User Multiple-Input Multiple-Output, multi-user-multiple-input multiple-output) technology allows the router to communicate with multiple devices at the same time, rather than communicating sequentially. [0003] In the prior art, when using OFDMA technology under Wi-Fi 6, different fr...
