Description

The setting of the subcarrier spacing of reference numerology/determine method, dress Put, base station and terminal

Technical field

The present invention relates to communication technical field, in particular to a kind of subcarrier of reference numerology The setting at interval/determine method, a kind of setting of the subcarrier spacing of reference numerology/determine device, one kind Base station and a kind of terminal.

Background technology

Following 5g communication prevailing scenario includes following three kinds: embb, mmtc and urllc.And these three scenes are targeted Type of service is different, and its demand is also different.

Such as embb (enhanced mobile broadband, enhanced mobile broadband) business, two main indexs It is high bandwidth and low time delay (requiring 4ms).The big bandwidth of 100mhz on following high-frequency communication, may be supported, and very may be used Sometime whole bandwidth can all be distributed directly to a user, and uplink scheduling time delay and harq (hybird automatic Repeat request, mixed automatic retransfer) feedback delay of technology also brings along time delay influence, so embb service needed is relatively Big subcarrier spacing and less time granularity.

And for example mmtc (massive machine type communications, a large amount of machine type communications) business, needs Be narrowband service, need battery life very long, this business is accomplished by the subcarrier spacing of smaller particle size and wider granularity Time-domain resource.

For urllc (ultra-reliable and low latency communications, highly reliable low time delay) Business, delay requirement is 0.5ms it is also desirable to domain scheduling granularity when reducing, uplink scheduling time delay and harq feedback delay bring Time delay influence.

In above-mentioned 5g communication scenes, in order to be adapted to the transmission demand of multiple communication services, for example, increase bandwidth and minimizing Time delay, needs to introduce multiple numerology in nr (new radio, new radio communication) system, such as embb business and The numerology subcarrier spacing of urllc business needs to increase, and minimum transmission units need to reduce.

In the lte method of correlation technique, the fixing subcarrier spacing of only one of which is 15khz, in this subcarrier spacing On the premise of, the length of subframe subframe is 1ms.So user according to acquiescence subcarrier spacing and subframe lengths with regard to energy According to synchronizing signal such as pss/sss, and/or reference signal crs/csi-rs/drs to be obtaining the synchronization of downgoing time, i.e. frame Synchronization, synchronizing sub-frame and sign synchronization.

And in 5g nr, different business may using different subcarrier spacings, that is, up-downgoing data is activation when Wait the subcarrier spacing of each user use and transmission time granularity may be different.But synchronous in initial downgoing time During, need all users that the subcarrier spacing of a reference numerology can be had to obtain frame synchronization and subframe Synchronous etc..

Therefore, how under unified framework of eating dishes without rice or wine, for different user setups and/or determination reference The subcarrier spacing of numerology is the Key technique problem realizing the synchronous communication between terminal unit and base station equipment.

Content of the invention

The present invention is based at least one above-mentioned technical problem it is proposed that a kind of son of reference numerology The setting at carrier wave interval/determine scheme, is the 2 of 15khz by arranging the subcarrier spacing of reference numerologyⁿ Times, and inform to terminal unit, so that terminal unit is determined to synchronize the reference of communication with base station equipment The subcarrier spacing of numerology is the 2 of 15khzⁿTimes, wherein, synchronous communication refers to the same of the Frame that terminal unit obtains Step, synchronizing sub-frame and sign synchronization.

In view of this, embodiment according to the first aspect of the invention is it is proposed that a kind of reference numerology Subcarrier spacing setting/determine method, comprising: the subcarrier spacing of setting reference numerology is 15khz 2ⁿTimes, and inform to terminal unit, the reference of communication can be synchronized with base station equipment with instruction terminal equipment The subcarrier spacing of numerology is the 2 of 15khzⁿTimes, wherein, n is the integer more than or equal to -2.

In this technical scheme, it is the 2 of 15khz by arranging the subcarrier spacing of reference numerologyⁿTimes, And inform to terminal unit, so that terminal unit is determined to synchronize the reference of communication with base station equipment The subcarrier spacing of numerology is the 2 of 15khzⁿTimes, wherein, synchronous communication refers to the same of the Frame that terminal unit obtains Step, synchronizing sub-frame and sign synchronization.

Wherein, the teachings at nr system sub-carriers interval are 3.75khz～480khz, and in order to adapt to different leading to The transmission demand of communication service, base station equipment can determine corresponding subcarrier spacing according to the transmission demand of communication service, setting The subcarrier spacing of reference numerology is the 2 of 15khzⁿTimes, while executing communication service, inform that terminal sets The subcarrier spacing of the standby reference numerology synchronizing communication is the 2 of 15khzⁿTimes, to ensure terminal unit Synchronous, synchronizing sub-frame and the sign synchronization of Frame is realized and base station equipment between.

It is preferable that also including in technique scheme: to all terminal units, identical is configured on same carrier wave The subcarrier spacing of reference numerology.

In this technical scheme, same carrier wave refers to that frequency is identical and one carrier wave of bandwidth identical.

It is preferable that also including in technique scheme: the subcarrier spacing that the specific downstream signal of setting takies is Reference numerology, and arrange send specific downstream signal first with reference to subframe, in first with reference to subframe with The subcarrier spacing specified sends specific downstream signal, can synchronize communication with base station equipment with instruction terminal equipment The subcarrier spacing of reference numerology is the subcarrier spacing of specific downstream signal transmission.

In this technical scheme, by specific descending letter being sent with specified subcarrier spacing in first with reference to subframe Number, the subcarrier spacing of the reference numerology of communication can be synchronized with base station equipment with instruction terminal equipment It is the subcarrier spacing of specific downstream signal transmission.

Specifically, the method for the implicit instruction of the subcarrier spacing based on reference numerology, detects spy The transmission bandwidth determining downstream signal is (m × n × 15 × 2ⁿ) khz, wherein, m is the number of the rb that specific downstream signal takies, n The number of the subcarrier comprising for each rb, this m and n be terminal unit chip in prestore, so according to specific descending The transmission bandwidth of signal, m and n can obtain the subcarrier spacing of reference numerology.

Specifically, the setting of subcarrier spacing of reference numerology can be realized in the way of using implicit instruction Put/determine, in the such as cell search process of lte network, pss (primary synchronization signal, main synchronization Signal)/sss (secondary synchronization signal, auxiliary synchronous signals) signaling numerology son load Wave spacing is 15khz, and subframe duration is 1ms.At this time base station equipment arranges a width of 72 (m × n of band that pss/sss signaling takies I.e. 6 × 12, each rb comprises 12 subcarriers, 6 rb centered on pss/sss transmission bandwidth) bandwidth of individual subcarrier, that is, 1.08mhz, when a length of 1 symbol of occupancy is 1/14ms.So when numerology is for 30khz, pss/sss signaling is still Occupied bandwidth is 72 subcarriers, carries a width of 2.16mhz, when a length of 1 symbol of occupancy is 0.5/14ms.

The like, pss/sss signaling take with 2 of 1.08mhz bandwidth in a width of lteⁿTimes when, reference The subcarrier spacing of numerology is the 2 of 15khzⁿTimes.
