Method and device for wireless resource scheduling in wireless network

Abstract

Embodiments of the present invention provide a method and device for wireless resource scheduling in a wireless network. According to the present invention, the radio resource management device can receive scheduling information from multiple base stations in a wireless network, generate scheduling reference information based on the scheduling information, and send the scheduling reference information to one of the multiple base stations, so that the base station can When scheduling radio resources for a terminal, radio resources already scheduled by multiple base stations may be taken into consideration. The present invention enables the wireless resource management device to effectively exchange the wireless resource information scheduled by each base station with multiple base stations in the network, thereby realizing effective resource allocation and resource sharing among multiple radio access technology base stations, and solving the problem of base station The independent scheduling problem reduces or eliminates uplink and downlink interference, improves resource utilization and effectively avoids system throughput loss.

Description

technical field [0001] The present invention generally relates to a multi-radio access technology (RAT: Radio Access Technology) network, and specifically relates to a method and a device for radio resource scheduling in a multi-RAT network. Background technique [0002] Existing wireless networks include multiple wireless access technologies, such as 2G, 3G, Long Term Evolution (LTE: Long Term Evolution), Advanced Long Term Evolution (LTE-A: Advanced Long Term Evolution), and the like. figure 1 is a schematic diagram of an existing multi-RAT network. like figure 1 As shown, there is a central controller in the existing multi-RAT network, that is, radio resource management equipment (RRME: Radio Resource Management Equipment) 110, which is connected to the core network 100 and connected to a A plurality of base stations (BS: Base Station) 120, 130, 140 and 150 of one or more RATs. The existing radio resource management device 110 can only manage information related to han...

Problems solved by technology

If there is no X2 interface between adjacent eNodeBs, ICIC technology cannot be used to eliminate the uplink and downlink interference between edge terminals

In addition, as specified in 3GPP TS 36.423, LI signaling includes information such as overload indication (OI: Overload Indication), high interference indication (HII: High Interference Indication) and relative narrowband transmission power (RNTP: Relative Narrowband Transmission Power), however , these information only provide information related to the physical layer resource block (PRB: Physical Resource Block), but fail to provide more information related to scheduling wireless resources for the terminal

[0004] It can be seen that in the existing multi-RAT network, the independent scheduling of base stations is not optimal in terms of system throughput, interference, power saving, resource utilization, etc.
