Disclosed is a wireless backhaul network for a communications system. The network comprises a congregate node connected to the communications system; a plurality of access points, each access point having associated amounts of incident bidirectional traffic to be conveyed to and from the congregate node; and a plurality of bidirectional wireless links adapted to convey the traffic between the access points and the congregate node. The congregate node is configured to allocate spectrum to each directional component of each link within a predetermined available spectrum for the conveyance of the traffic, wherein the allocation is dependent on the amounts of traffic at the respective access points.

The present invention provides two primary Hybrid Automatic Repeat reQuest (HARQ) mechanisms for a multi-hop network, i.e. an active Mobile Multi-hop Relaying (MMR) HARQ and a passive Mobile Multi-hop Relaying (MMR) HARQ. According to the solution of the present invention, there are provided a method and a device for HARQ retransmission in relay stations of a wireless communication network, wherein in HARQ retransmission, the HARQ procedure is implemented based on resource allocated by a base station; and a method and device for HARQ in a base station, characterized in that a HARQ procedure is implemented in-between one or more relay stations and a mobile station. With the methods of the present invention, the HARQ problems existing in a multi-hop network are overcome, the correction rate of data transmission is improved, while time delay for data transmission is reduced.

A new data packet transmission solution is provided in the present invention. Firstly, a source network equipment sends a duplicate of a data packet to a sponsor relay station and other one or more assistant relay stations; then the one or more assistant relay stations transmit the duplicate of the data packet received to the sponsor relay station. After the sponsor relay station receives the duplicate directly transmitted by the source and a plurality of duplicates which are transmitted by one or more assistant relay stations, it applies a joint processing of several duplicates of the data packet, and then transmits the result of the joint processing to a corresponding network equipment. Preferably, after one or more assistant relay stations transmit the duplicates of the data packet to the sponsor relay station, the destination network equipment also receives one or more duplicates, and applies a joint processing of the one or more duplicates and a duplicate of the data packet which is received from the sponsor relay station.
摘要:
When a positive voltage of V1 is applied to a drive capacitor with a braking voltage V2 at 0V, a moveable electrode moves toward the drive electrode, and a capacitance C of a tunable capacitor becomes smaller. When the braking voltage V2 is applied a lower portion brake electrode of the brake capacitor moves in a horizontal direction, such that the inter electrode separation distance between an upper portion brake electrode and the lower portion brake electrode becomes 0 μm. The moveable electrode configured integrally formed with the lower portion brake electrode also moves in the horizontal direction, and the inter electrode separation distance between the moveable electrode and a fixed electrode becomes 0 μm. Since the two electrodes make contact with each other with a dielectric layer interposed therebetween, the position of the moveable electrode can be stably maintained by frictional force between the electrodes.
