Problems solved by technology

However, the existing relay station transmits a backend control message in a low-priority user plane connection, which causes delay in transmission
Second, transmitting a backend control message in a user plane requires the establishment of an IP layer, which wastes radio resources in the wireless link

Abstract

A base station, a relay station and a backhaul control communication thereof are provided. A wireless communication system comprises the relay station, a base station, and a core network. The relay station is wirelessly connected to the base station, while the base station is wiredly connected to the core network. The relay station comprises a processing unit and a transceiver. The processing unit is configured to create a radio link having a control plane connection between the relay station and the base station and create a backhaul link between the relay station and the base station by the control plane connection of the radio link. The transceiver is configured to transmit a backhaul control message to the core network via the backhaul link.

Description

technical field [0001] The invention relates to a base station, a relay station and a back-end control communication method thereof. More specifically, the base station, the relay station and the backhaul control communication method thereof of the present invention transmit backhaul control messages in a control plane connection of a radio channel. Background technique [0002] At present, wireless communication technology has been widely used. Figure 1A A schematic diagram of an existing wireless communication system 1 is shown. The wireless communication system 1 includes a user equipment (user equipment) 11 , a relay station 13 , a base station 15 and a core network 17 . The UE 11 is wirelessly connected to the relay station 13 , the relay station 13 is wirelessly connected to the base station 15 , and the base station 15 is wired to the core network 17 . [0003] The relay station 13 is used to extend the service coverage area of ​​the core network 17, so that a user...
