Embodiment Construction
[0023] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0024] The Physical Cell ID (PCI, Physical Cell ID) of the LTE network has a value ranging from 0 to 503, and there are 504 PCIs in total. Each LTE cell needs a PCI to distinguish it from neighboring cells; when a terminal accesses the network, it can determine and access each physical cell according to the PCI. The number of cells in an LTE network is inexhaustible, but there are only 504 physical cell identities, so PCI must be reused; if different cells use the same PCI, it is necessary to ensure that the distance between these cells is far enough—that is, the reuse distance is sufficient In order to avoid confusion and interference when accessing the terminal.
[0025] The reference signal is used for channel measurement and demodulation signals in ...
