Description

technical field

[0001] The embodiments of the present application relate to the technical field of communication, and more specifically, to a method for sending a reference signal used for detecting common control information or multicast / broadcast information in wireless communication. Background technique

[0002] The current wireless communication technology has been developed to LTE (full name in Chinese: Long Term Evolution; full name in English: LongTerm Evolution) system, with figure 1 For example, the existing LTE system includes multiple cells, and each cell has a base station 11 and multiple terminals 12, and the base station sends public control information and data to the terminals, as well as references for detecting public control information and data. Signal.

[0003] In the existing LTE R8-R12 system, there are three main types of reference signals used for downlink channel measurement and data demodulation: CRS (full name in Chinese: Cell-specific Reference...
