  • Publication number: 20200382248
    Abstract: Embodiments of the present disclosure relate to a method and device for backhaul transmission. In example embodiments, the first network device transmits uplink (UL) data to a second network device in a first UL backhaul link, the first UL backhaul link being scheduled by the first network device. The second network device is located in upstream of the first network device. The first network device receives downlink (DL) data from the second network device in a first DL backhaul link. The first DL backhaul link is scheduled by the second network device. In this way, the transmission latency may be reduced, and the transmission efficiency may be improved.

  • Patent number: 9037077
    Abstract: A relay method and device, wherein the control signal and the data signal which are in the same subframe are directly sent to a lower level device respectively by an upper level device and a relay function device. In one example, the relay function device transmits data signal using subscriber special reference signal to make the lower level device estimate an access channel correctly; in another example, the relay function device carries out precoding of the data signal correlative with the access channel so as to cancel the influence of the access channel, thereby make the lower level device receive data signal correctly. Retransmission control signaling is sent to the lower level device in each subframe by the upper level device to ensure the fixed sequential relationship of feedback retransmission.

  • Patent number: 8837356
    Abstract: Disclosed are a method for identifying a connection, mobile station and base station. The method comprises the steps of: assigning a MS ID to the mobile station when the mobile station enters into the coverage area of the base station; and assigning a connection ID to a connection when the connection is established between the base station and the mobile station. With the proposed solution, the data overhead could be reduced due to short Connection ID instead of 16-bit CID in 802.16e, especially for VoIP traffic. In addition, due to adjustable bit-length of Connection ID, the tuple <MS ID, Connection ID> could flexibly support different numbers of connections while keeping overhead in minimal.

  • Patent number: 8638675
    Abstract: A method and a device for data relay transmission in a wireless relay communication network are provided, in which, the relay station directly obtains corresponding egress CID related information based on input MAC PDUs, then generates output MAC PDUs including the egress CID related information, and at last, according to the egress CID related information, performs QoS scheduling for the output MAC PDUs, so as to output them in an sequence of QoS. The invention omits the steps of de-cascading, de-segmenting or de-capsulating the MAC PDUs in order to obtain MAC SDUs, and the steps of scheduling by category, cascading, segmenting, and encapsulating the MAC SDUs in order to re-generate the MAC PDUs in the prior art, and the invention simplifies the data processing procedure and achieves the goal of decreasing the relay latency.

  • Patent number: 8203966
    Abstract: The invention relates to methods and devices for setting up connection for wireless relay network, wherein, mobile station utilizes the primary transmission path from itself and relay stations in the initial ranging and network entry procedure to send a request signal to base station. After the base station receives the request signal, it allocates a transmission path for the mobile station, and sends the information to the relay station on the path along the primary transmission path, and sends a response message to the mobile station. When the mobile station and the related relay stations obtain the corresponding response message and transmission path information, the signal sent by the mobile station is sent to the base station via relay stations along the transmission path.
