METHOD AND APPARATUS FOR RELAYING SIGNAL IN WIRELESS NETWORK

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.
