Resource regulating method and resource scheduling device

Technical field

The present invention relates to communication technical field, in particular to a kind of resource regulating method and a kind of scheduling of resource dress Put.

Background technology

Existing 4G and 4.5G mobile communication technology, (Long Term Evolution, drills for a long time to be all based on LTE Enter) and the wireless access technology of LTE-A (LTE-Advanced), running time-frequency resource granularity and frame structure etc..Such as current LTE system The a width of 20MHz of maximum single carrier band that can support, to support bigger bandwidth, can only rely on carrier aggregation (Carrier Aggregation, abbreviation CA) use.In addition, current frame structure mainly includes：FDD(Frequency Division Duplexing, FDD) frame structure, TDD (Time Division Duplexing, time division duplex) frame structure and LAA The dynamic frame structure that (LTE Assisted Access, LTE auxiliary accesses) unauthorized carrier wave uses.Regardless of frame structure, All comprise 10 subframes, each subframe is 1ms, each subframe comprises two slot (time slot), a slot is 0.5ms, each Slot comprises 7 symbol (symbol) again.Frequency domain aspect, in LTE system, subcarrier spacing is mainly 15KHz, a RB (Resource Block, Resource Block) contains 12 subcarriers.And in NB-IoT (Narrow Band Internet of Things, the arrowband Internet of Things based on honeycomb) in a kind of subcarrier spacing of new 3.75KHz proposed again, and NB-IoT Carrier bandwidths only have 180KHz.

In terms of resource allocation, FDD frame structure and tdd frame structure be all with 1ms subframe for when domain scheduling granularity, except DwPTS (Downlink Pilot Time Slot, descending pilot frequency time slot) in special subframe in tdd frame structure is used for transmitting During data, when domain scheduling granularity be less than 1ms's.Also multiplexing is occurred in that in the same frame structure in the use of LAA unauthorized carrier wave DwPTS, as the descending scheduling time domain granularity of partial subframe, also using the scheduling granularity of the whole subframe of 1ms simultaneously. And in FDD frame structure and tdd frame structure, except the existing down sending time of the special subframe in tdd frame structure and up Send outside the time, or other subframe is all up transmission or descending transmission time domain separates frequency domain separately.

It can be seen that, the granularity of current frame structure and frequency domain resource all can make resource allocation underaction, and uplink scheduling The time of mechanism and HARQ (Hybrid Automatic Repeat Request, hybrid automatic repeat-request) feedback mechanism etc. Interval makes time delay larger again, and 20MHz bandwidth is also unsatisfactory for high bandwidth requirements.
