Abstract

The invention discloses a resource allocation method for an uplink channel of a smart power grid based on an NB-IoT protocol. The method comprises the following steps: 1, sampling data to be monitoredby different types of sensors in the smart power grid; 2, encoding the sampled data according to the sensor numbers and sampling times; 3, performing channel diversity processing on the coded data according to burst interference distribution detected in the detection link; and 4, according to the total resource size and the channel diversity frequency of the wireless system, allocating an optimaltransmission scheme to each data, and transmitting the data to an NB-IoT wireless private network base station more effectively. According to the invention, frequency spectrum resources can be betterutilized, so that the throughput rate and the anti-interference capability of a wireless transmission system are improved, and reasonable resource allocation is achieved.
