In some embodiments the backhaul link comprises a radio link.

Especially, the connecting pipe is flexible.

In this way, the availability of a wireless backhaul network is increased and, hence, the outage probability of backhauling decreased in connection with providing a more robust backhauling.

The base station is communicatively coupled to a back haul (410-1) for routing one or more messages through the back haul to a destination.

The embodiment of the present invention reduces the influence of interferences in the relay node equipment upon a backhaul link, and improves the performances of the wireless backhaul link.

A wireless communication system (1) is a wireless backhaul.

Disclosed are a pre-configuration method and system for a backhaul link.

According to the invention, the connection piece is characterised in that the hollow shaft (1) comprises a press stopper (8) in the connection area between the hollow shaft (1) and the connection component (2).

The portable observer also comprises a connecting pipe (21) connected the camera with the main body.

By way of the present invention, effective transmission of the A-SRS in the backhaul link can be achieved.

The present invention achieves the effect of using the backhaul link to send ACK/NACK information.

A vibratory exciter apparatus (10.) can be interchangeably connected to a variety of diverse vibratory compaction and other earth-working vibratory tools and includes a vibration-isolating connection link to tool carriers of varying sizes.

The inventive connection piece limits production costs, mounting and maintenance.

Disclosed are a method and system for processing backhaul link ACK/NACK information.

Additionally, in backhaul link transmission, it may use a different frequency reuse scheme.
