摘要： Disclosed are a packet scheduling method and apparatus in a relay network. A scheduling method of a relay station in a relay communication system includes: receiving information regarding an amount of generated data to be transmitted to a user from a base station; estimating the size of a queue of the base station storing the data to be transmitted to the user based on the amount of generated data received from the base station; obtaining the size of a virtual queue in which overall data to be transmitted to a user with reference to the estimated size of the queue of the base station and the size of a queue of the relay station storing data to be transmitted to a user; performing scheduling to allocate resource based on the size of the virtual queue; and transmitting data to the user based on the scheduling results.

摘要： Disclosed are a control method and a control device for implementing two-way communication in a wireless network. A repeater can measure a channel matrix, which indicates channel information of each of a plurality of nodes based on signals received simultaneously from the plurality of the nodes, and calculate a first basic lattice size, which initializes the lattice sizes of the received signals according to predefined rules. Then, the repeater uses the channel matrix of each of the nodes and the initialized first lattice size to calculate for each of the nodes a first normalization factor, which normalizes the sizes of the signals simultaneously received from each of the nodes, and a minimum normalized factor, which is equivalent to the minimum value of the first normalization factor. And then, the repeater calculates a second lattice size for each of the nodes using the first normalization factor, the minimum normalization factor, and the initialized first lattice size, which have been calculated for each of the nodes. Then, the repeater calculates a second normalization factor using the second lattice size and the channel matrix of each of the nodes. And then, the repeater transmits the new calculated lattice size and the normalization factor to each of the nodes.
