PROBLEM TO BE SOLVED: To support multiple wireless access technologies at a common terrestrial radio access network.SOLUTION: Wireless resources can be reserved in a manner that enables transmission of control and reference signals to advanced or emerging-technology user terminals (e.g., LTE-A), while mitigating adverse effects on legacy user terminals (e.g., LTE Release 8). Therefore, information designated for LTE-A terminals can be embedded in predetermined reserved locations, which exploit known standardized behavior of legacy terminals in expecting information at specific locations. Such a reservation of resources can be made typically without affecting the legacy terminals, and thus performance degradation of legacy terminals can be mitigated or avoided. |
