First Claim
Patent Images
1. A gateway to communicate with sensor nodes, the gateway comprising:
- a generator configured to generate, based on schedule information on a previous uplink interval, response data;
an allocator configured to allocate a subsequent uplink interval to the sensor nodes to generate schedule information on the subsequent uplink interval; and
a transmitter configured to transmit the response data and the schedule information on the subsequent uplink interval to the sensor nodes.

Abstract
A gateway and method thereof are provided to communicate with sensor nodes. The gateway includes a generator configured to generate, based on schedule information on a previous uplink interval, response data. The gateway also includes an allocator configured to allocate a subsequent uplink interval to the sensor nodes to generate schedule information on the subsequent uplink interval. The gateway includes a transmitter configured to transmit the response data and the schedule information on the subsequent uplink interval to the sensor nodes.

14. A sensor node, comprising:
-
an extractor configured to extract schedule information from a subsequent uplink interval and response data included in a synchronization signal; a verifier configured to verify, based on the response data and schedule information on a previous uplink interval, whether data transmitted in the previous uplink interval is retransmitted; and a transmitter configured to transmit data to a gateway based on the schedule information on the subsequent uplink interval and a result of the verifying. - View Dependent Claims (15, 16, 17, 18, 19)
