Document Type and Number:
WIPO Patent Application WO/2018/119943
Kind Code:
A1
Abstract:
Provided in the embodiment of the present application are a channel identification method and device. In one aspect, in the embodiment of the present application, receiving a signal on a first system frequency band; generating a joint matrix comprising a channel parameter and a spreading code according to the signal received from the first system frequency band and a transmission signal matrix; obtaining a target matrix according to the joint matrix; and according to the target matrix, obtaining a spreading code used by the first system, the spreading code being used to identify the channel occupied by the first system. Therefore, the technical solution provided by the embodiments of the present application can identify the occupied channel in the communication system without performing additional communication.
