Embodiment Construction

[0052] This application proposes an access method. By providing the access signal format, the product design and product networking restrictions of the RF feed-in digital distribution system are reduced. The basic principle is: the radius of the cell is strongly correlated with the length of the GP in the access signal The principle is to plan the cell radius that meets the expected transmission time, and determine the GP length according to the planned cell radius, so that the planned cell radius meets the transmission time requirements of the products of the RF feed digital distribution system, and reduces the RF feed digital distribution system. Product design and product networking limitations.

[0053] The access network device described in this application is the network-side device that provides access services for terminals in the cellular mobile network. In cellular mobile networks of different standards, the access network equipment may have different names, but they...
