Embodiment 1
[0068] The operator's spectrum resources are just enough to form a network and meet the minimum bandwidth requirements of each standard. Embodiment 1 mainly considers the most common FDD network of the mobile communication network: GSM, UMTS, and LTE coexist. The bandwidth of each carrier frequency in the GSM system is 200kHz, but GSM has certain frequency reuse requirements. For example, it needs to meet the frequency reuse degree of 4*3. If one carrier frequency per cell is satisfied, the total bandwidth resources required = each carrier frequency Bandwidth * frequency points = 200kHz * 12 = 2.4MHz; the system bandwidth of each carrier frequency of UMTS is 5MHz; LTE supports 1.4 / 3 / 5 / 10 / 15 / 20MHz, but the larger the system bandwidth, the more it can reflect the high spectral efficiency of the LTE system , usually the system bandwidth of the LTE network requires 5MHz or more. Therefore, the first embodiment of the present invention considers that the operator's total frequency...
Embodiment 2
[0180] In an embodiment of the present invention, the current most common FDD system is taken as an example to illustrate that a multi-standard system can be completely shared on the same spectrum resource, and other FDD systems such as CDMA and TDD systems such as TD-SCDMA systems can also be used in the first embodiment. The technology realizes the complete sharing of spectrum resources. Likewise, it is also common to future communication systems that are gradually emerging.
Embodiment 3
[0182] An embodiment of the present invention emphasizes the minimum requirement of an integrated GSM / UMTS / LTE system, complete spectrum sharing on 5MHz spectrum resources. When the spectrum resource of the operator exceeds 5 MHz, the technology in the embodiment of the present invention is also applicable. In addition, if the spectrum resources are sufficiently loose between multiple standard systems, part of the spectrum resources can be shared, making resource utilization more reasonable and providing users with better services.
