Wireless resource scheduling method and wireless resource scheduling system

Abstract

The invention discloses a wireless resource scheduling method and a wireless resource scheduling system. The wireless resource scheduling method comprises the following steps: a base station distributes N subframes for a user equipment UE according to the volume of downlink / uplink data to be transmitted; N is a natural number larger than 1; the base station sends a subframe interval parameter S to the UE; the base station sends the number N of subframes distributed for the UE to the UE through a physical downlink control channel PDCCH; the UE determines the corresponding N subframes according to the number N of subframes and the subframe interval parameter S and transmits the downlink / uplink data on a physical downlink shared channel PDSCH resource / physical uplink shared channel PUSCH resource for the determined N subframes. The technical scheme of the invention can effectively improve the utilization factor of the wireless resources.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a wireless resource scheduling method and system. Background technique [0002] In the existing Long Term Evolution (LTE) system, two wireless resource scheduling methods are provided, which are the dynamic scheduling method and the semi-persistent scheduling method. [0003] Dynamic scheduling mode: The base station (eNode B) allocates corresponding radio resources to UEs in real time according to the uplink and downlink traffic volume, and each scheduling behavior only allocates radio resources used within the Transmission Time Interval (TTI, Transmission Time Interval) for UEs. If the resources scheduled in one TTI cannot accommodate all the cached data, more resources need to be continuously scheduled in subsequent TTIs until all the cached data is correctly transmitted. The advantage of this method is that resource allocation is flexible, but the disadv...

Problems solved by technology

For example, when users use MSN, Tencent QQ and other instant messaging tools, they need to stay online all the time, and the amount of information that needs to be transmitted occasionally is generally on the order of tens of kilobits to several megabits, and its data arrival time characteristics do not meet the requirements of semi-persistent scheduling. requirements, only dynamic scheduling can be used

However, the resources allocated by one PDCCH dynamic scheduling instruction are not enough to transmit all data, because currently one PDCCH dynamic scheduling can only allocate one TTI physical downlink shared channel (PDSCH) resource or one TTI physical uplink shared channel (PUSCH) resource, Multiple PDCCHs are often required to complete the transmission of all data

The problem with such multiple dynamic scheduling is that the control channel PDCCH has a large overhead, which is not conducive to the rational use of wireless resources.

[0008] It can be seen that for always-on services, the existing dynamic scheduling methods and semi-persistent scheduling methods cannot achieve efficient use of wireless resources
