A data transmission method of a base station in a radio relay communication system include: obtaining, by a first BS, first radio resource information scheduled by a neighbor BS with respect to a first relay node (RN) located within the coverage of the first BS; when the first BS has data to be transmitted to the first RN, scheduling the data of the first BS on first radio resource allocated by the neighbor BS; and transmitting, by the first BS, the data of the first BS on the first BS, wherein the first RN is located within an overlapping cell coverage between the first BS and the neighbor BS. Thus, backhaul link transmission efficiency between the BS and the RN in the relay communication system can be improved and an inter-cell interference with respect to a backhaul link can be reduced.

    摘要： Techniques for supporting MIMO transmission are described. User equipments (UEs) are classified into a first group of UEs to be scheduled individually and a second group of UEs that can be scheduled together. The classification may be based upon the number of transmit and receive antennas, sector loading, data requirements, long-term channel statistics, the number of UEs, etc. Channel quality indicator (CQI) information received from the UEs is interpreted in different manners depending on the groups to which the UEs belong. A single UE may be selected at a time from the first group or multiple UEs may be selected at a time from the second group for MIMO transmission. A MIMO transmission may be sent to a single UE in the first group or multiple UEs in the second group at rates selected based upon the CQI information.

    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.
