Embodiment Construction

[0027] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0028] Such as figure 1 As shown, this is the system architecture of the chain network. figure 1 The CCU (Central Control Unit, Central Control Unit) in the network is responsible for completing functions such as network management, security authentication, and routing and forwarding. figure 1 The row below the central CCU is the backbone chain network, which consists of multiple FNUs (Fix Node Units) arranged in sequence to form a chain distribution. The node directly connected to the CCU by cable is called the head node, and the other nodes are common nodes. Each FNU has a backbone communication link in two directions (forward and backward), FL (Forward Link, forward link) is a link that deviates from the direction of the first node, BL (Backward Link, backward link) is A link pointing in the direction of the head node. The logical entity controlling the ...

Abstract

The invention provides a wireless-chain-network-under MIMO self-adaptive method, which comprises the following steps. A MASTER entity sends system information periodically. A SLAVE entity receives the system information. The SLAVE entity utilizes one of the transmission modes compatible with the MASTER entity to send an access request to the MASTER entity. The MASTER entity detects the access request. The MASTER entity sends to the SLAVE entity an access respond. The SLAVE entity demodulates the access respond information. The SLAVE entity sends to the MASTER entity a scheduling request. The MASTER entity detects and demodulates the scheduling request information. The MASTER entity replies to the SLAVE entity the scheduling resource distribution information. The SLAVE entity detects and demodulates the scheduling resource distribution information. With the method, it is possible to enable different numbers of antennas to access a wireless chain network.

Description

technical field [0001] The invention belongs to the technical field of wireless communication networks, and relates to an adaptive MIMO scheme of a wireless chain network. Background technique [0002] The wireless chain network is suitable for wireless networks with communication requirements in band or tree areas. These areas, such as: rivers and lakes, oil pipelines, border and coastal defense and other areas. These areas are sparsely populated, covered in long lengths, have harsh natural environments, and lack infrastructure. Difficult to use the existing WiMAX, cellular mobile communication mechanism. [0003] The backbone network of the wireless chain network is composed of multiple fixed nodes arranged in sequence to form a chain distribution. Each node communicates with each other. Each node has a backbone communication link in two directions, which can provide rich access opportunities for peripheral devices. , so other terminal devices can access the network thr...
