Distribution of system access information in wireless communication system

Abstract:

The present disclosure relates to methods for efficiently transmitting system access information that is used by wireless terminals (200) to access a cell (20) in a wireless communication network (10). The system access information may include synchronization signals, system information, or reference signals used for channel estimation. In exemplary embodiments of the disclosure, the access nodes (100) within the wireless communication network (10) may be configured to operate in two or more operating modes. The information density of the system access information transmitted by the access node varies depending on the operating mode. For example, the access node (100) may vary the information density by varying the amount of system access information that is transmitted or the periodicity of the system access information that is transmitted.
