Abstract

The invention discloses a pilot frequency configuration method based on an OCC. The method comprises the following steps: a client of the communication system determines an OCC sequence length based on a classification type and a channel characteristic corresponding to the client, then, the client expands the pilot frequency corresponding to the client based on the OCC sequence length; and then the client sends the extended pilot frequency to a base station of the communication system, the extended pilot frequency comprises a classification type corresponding to the client, and the base station allocates resource blocks to the extended pilot frequency according to the classification type. The invention further discloses a device, a system and a storage medium. According to the invention, the clients are classified, and different pilot frequencies are configured for the clients of different classification types, so that the signal transmission efficiency of the communication system is improved while the system requirements are met.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a pilot configuration method, device, system and storage medium based on OCC (Orthogonal Cover Code, orthogonal mask). Background technique [0002] Wireless local area network is the application of wireless communication technology to interconnect computer equipment to form a network system that can communicate with each other and realize resource sharing. With the development of mobile communication technology, WLAN is connected in a wireless way, so that the construction of the network and the movement of the terminal are more flexible. [0003] Pilot design is one of the core contents of the network system. Pilots can be used for user identification and channel estimation. The accuracy of channel estimation will determine the performance of the system. The Internet of Things is an important application scenario in 5G communication. In the Internet of Things, a ...
