Abstract: A base station infers a random access failure rate depending on a random access collision of terminals performing random access and controls a random access opportunity of a terminal that fails the random access by using the random access failure rate of each terminal. Also, information for the controlled random access opportunity is transmitted to the terminal that fails the random access.

Abstract: Provided are a communication method based on device's property and an apparatus for allocating a resource by using the method. Devices are classified based on the device's property and a signal including information based on the resource allocation to the devices is transmitted to the devices. Data are received from a device through the allocated resource. Here, the devices transmitting pilot signals including device data values corresponding to preset expected reference data information transmit data through the allocated resource.

Abstract: An LDPC decoding method of a received signal including a plurality of received symbols is provided. A decoding apparatus selects a perturbation space in which perturbation is to be performed based on a code length of the received signal and a maximum number of perturbation rounds indicating a number of perturbation rounds that can be performed, and performs a perturbation round. The decoding apparatus performs perturbation on a corresponding received symbol among the plurality of received symbols in each perturbation round, and decodes the received signal on which the perturbation has been performed. The decoding apparatus determines that decoding is successful when there is a perturbation round in which a decoding result of the received signal satisfies a predetermined condition.
