| 20080285502 | METHOD AND DEVICE FOR RELAY STATION TO FORWARD DOWNLINK SIGNAL - A method for relay stations (RSs) to forward downlink signals includes: obtaining downlink qualities between a mobile station (MS) and each of the RSs; determining an RS group for forwarding downlink signals according to difference degrees among all of the downlink qualities; performing space-time coding on the downlink signals through the RSs in the RS group when the RS group contains a plurality of RSs. Another method for RSs to forward downlink signals includes: setting the number of the RSs for forwarding the downlink signals to plurality; obtaining downlink qualities between an MS and each of the RSs; determining an RS group for forwarding the downlink signals according to each of the downlink qualities and the number of the RSs; performing space-time coding on the downlink signals through the RSs in the RS group, and forwarding the downlink signals to the MS. A device structure for the RSs to forward the downlink signals is also provided. | 11-20-2008 |

| 20090213779 | MULTI-HOP WIRELESS RELAY COMMUNICATION SYSTEM AND DOWNLINK DATA TRANSMITTING METHOD AND DEVICE - A downlink data transmitting method is applied to a multi-hop wireless relay communication system. The method includes the following steps. A network unit obtains an identifier of a next hop network unit corresponding to a connection identifier (CID) in a downlink medium access control protocol data unit (MPDU) header according to an existing corresponding relationship of the CID and a path ID, and sends the downlink MPDU to the next hop network unit by utilizing the obtained identifier of the next hop network unit, so that a data transmission of multi-hop wireless communication system is realized without changing a current user terminal and protocol structure of a core network. Meanwhile, a multi-hop wireless relay system, and a base station and relay stations applied to the system are described. | 08-27-2009 |
| 20090217119 | METHOD, SYSTEM AND RELAY STATION FOR REALIZING HYBRID AUTOMATIC RETRANSMISSION - A method for implementing hybrid automatic retransmission is provided in a communication system. In the method, a terminal transmits a data block to a receiving side through a relay station; the relay station returns a receiving status of the relay station to the receiving side; and the transmitting side determines whether retransmission of the data block is needed according to the receiving status. A system for implementing hybrid automatic retransmission and a relay station are described, also. Accordingly, the system performance is enhanced, the transmission quality is improved. In addition, the relay station is transparent to the terminal such that no modification is required to be made to the existing terminal in the system having a relay station. | 08-27-2009 |
| 20090221288 | METHOD FOR IMPLEMENTING RANDOM ACCESS OF NEW ACCESS NODE AND COMMUNICATION SYSTEM THEREOF - A method for implementing a random access of a new access node and a system thereof are provided, which belong to a wireless communication field, and enable the new access node within the coverage of relay stations to implement the random access. In the application, when the new access node is located within the coverage of the relay stations, each of the relay stations notifies an access request sent from the new access node to a synchronization station via a report message, and the synchronization station compares the access request forwarded by each of the relay stations and the access request received by itself from the same new access node, selects a station with the best signal quality of the received access request, and implements the access of the new access node in accordance with the types of selected station and the synchronization station itself. | 09-03-2009 |
