Embodiment Construction

[0041] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] seefigure 1 as shown, figure 1 Describes the wireless access and backhaul integrated small base station solution diagram, including core network 101, macro base station (MacroBasestation, MBS) 102, small base station (SmallBasestation, SBS) 103, users (Users, UE) 104, wireless devices 105, A wireless backhaul link 106 and a wireless access link 107 . In the LTE-based system in this embodiment, the base station is connected with the base station through the X2 interface, and the optical fiber is used to realize the connection, and the user plane communicates through the X2-U interface, and the main protocol is GTP-U. After the introduction of SBS103 into the wireless self-backhaul system, SBS103 needs to be transmitted via Ethernet after GTP protocol encapsulation, and has changed to interact with MBS102 through the air interface. It...

Abstract

The invention relates to a prototype design method of a small base station integrating wireless access and backhaul, and belongs to the technical field of wireless communication. According to the realization principle of the wireless self-backhaul system, the method designs the integrated scheme diagram of wireless access and backhaul. Clarify the signaling and data processing flow, and design the user plane protocol stack level of the wireless access and backhaul integrated system. Based on the backward compatibility of the TDD frame structure of LTE, the design of the next-generation frame structure for wireless self-backhaul supports small base station wireless self-backhaul. The design includes a suitable PHY layer framework, self-backhaul subframes and ordinary subframes Frame design, backhaul link control signal and access link resource multiplexing method, etc. The present invention can well integrate the wireless access link and the backhaul link of the small base station, and can realize the integrated design of the wireless self-backhaul small base station.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a prototype design method of a small base station integrating wireless access and backhaul. Background technique [0002] With the popularization of smart terminals and the enrichment of mobile broadband services, network traffic continues to increase. In order to meet the rapid development of mobile data services, operators need to increase network capacity by acquiring more spectrum resources and improving spectrum efficiency. A macro base station (MBS) can achieve the purpose of increasing cell density by splitting the cell or increasing the number of base stations, but the installation space requirement of the macro base station is relatively high, and site acquisition is difficult. Therefore, in the upcoming 5G communication system, the low-power wireless access and backhaul integrated small base station (SmallBasestation, SBS), that is, the wireless self-backh...
