Abstract
A method for synchronizing a wireless communication system is disclosed. A silence duration for a base station is determined based on the time required for a neighbor base station to obtain or maintain synchronization. All transmissions from the base station are ceased for the silence duration. Multiple base stations level may cease transmissions at the same time, thus mitigating interference.
Claims20
A method for synchronizing a wireless communication system, comprising:
- determining a stratum level of a base station, the stratum level corresponding to a number of base stations including a global timing source node and zero or more_intermediate base stations between the base station and the global timing source node;
- and
- monitoring for signals from at least one of a neighbor base station or the global timing source node during a time duration determined at least, in part, by the stratum level;
- receiving a network-wide global time from at least one neighbor base station or the global timing source node during the time duration.
An apparatus for synchronizing a wireless communication system, comprising:
- a processor;
- memory in electronic communication with the processor and containing instructions executable by the processor to:
- determine a stratum level of a base station, the stratum level corresponding to a number of base stations including a global timing source node and zero or more intermediate base stations between the base station and the global timing source node;
- and
- monitor for signals from at least one of a neighbor base station or the global timing source node during a time duration determined at least, in part, by the stratum level;
- receive a network-wide global time from at least one of a neighbor base station or the global timing source node during the time duration.
An apparatus for synchronizing a wireless communication system, comprising:
- means for determining a stratum level of a base station, the stratum level corresponding to a number of base stations including a global timing source node and zero or more_intermediate base stations between the base station and the global timing source node;
- and
- means for monitoring for signals from at least one of a neighbor base station or the global timing source node during a time duration determined at least, in part, by the stratum level;
- means for receiving a network-wide global time from at least one of a neighbor base station or the global timing source node during the time duration.
A computer-program product for synchronizing a wireless communication system, the computer-program product comprising a non-transitory computer-readable medium having instructions thereon, the instructions comprising code for causing a computer to perform the steps of:
- determining a stratum level of a base station, the stratum level corresponding to a number of base stations including a global timing source node and zero or more_intermediate base stations between the base station and the global timing source node;
- and
- monitoring for signals from at least one of a neighbor base station or the global timing source node during a time duration determined at least, in part, by the stratum level;
- receiving a network-wide global time from at least one of a neighbor base station or the global timing source node during the time duration.
