Description

Ascending frequency-hopping method and device
Technical field
The present invention relates to fields of communication technology, fill in particular to a kind of ascending frequency-hopping method and a kind of ascending frequency-hopping It sets.
Background technique
Currently, with the development of mobile internet, having emerged the applied business for largely meeting various specific functions.Wherein Some business are lower to data delay requirement, such as receiving and dispatching mail, downloading film etc.；But in addition there are some business to data delay There are a strict requirements, such as network on-line game, rush to purchase, rob red packet etc., this kind of business is usually required the time delay of user data It is short as far as possible.In LTE (Long Term Evolution, long term evolution) system, Transmission Time Interval (TTI, Transmission Time Interval) it is the important indicator for influencing user data delay.What current LTE system used TTI (legacy TTI hereinafter) is 1ms namely subframe, and the every 1ms of transmitting terminal sends a data block, and receiving end can be every 1ms receives a data block.
In 3GPP (3rd Generation Partnership Project, third generation partner program) RAN To the TTI for using shorter duration in LTE system in (Radio Access Network, wireless access network) #69 plenary session The feasibility and possible beneficial effect of (short TTI, i.e. sTTI, such as 0.5ms, 0.2ms etc.).Current some document examples As R1-160942, R1-160930 quantitatively have studied the influence of the reduction of TTI duration to the data delay of LTE system, analysis It has been shown that, not merely makes the Transmission Time Interval of base station, terminal shorten, correspondingly, with the Transmission Time Interval phase using sTTI Corresponding data processing time can also decrease, such as data code modulation and data demodulation time all can be with data blocks The reduction of size and reduce.It is possible that legacy TTI and two kinds of transmission times of sTTI in the LTE system of later release The case where interval coexists, generally for the ease of network data processing, the duration of a legacy TTI is equal to N, and (N > 1, N are whole Number) a sTTI duration, and the time domain boundary alignment on the time domain boundary of legacy TTI and sTTI, specific example just like Fig. 1 It is shown, wherein the when a length of 0.2ms of the when a length of 1ms of legacy TTI, sTTI.
For the uplink spectrum of traditional LTE system using only legacy TTI, in order to be randomized interference, user is being sent out Frequency hopping would generally be used by sending when data, be described as follows about ascending frequency-hopping:
Ascending frequency-hopping mode includes: frequency hopping between frequency hopping and subframe in subframe.Wherein, frequency hopping refers in a subframe in subframe Two slot (time slot) on carry out frequency hopping, be capable of providing frequency in a transmission block (Transport Block, TB) point Collection.Frequency hopping aims at the different HARQ of the same TB (Hybrid Automatic Repeat Request, mixing is automatic between subframe Retransmission request) retransmit between frequency diversity is provided.
For frequency hopping in subframe, frequency-hopping mode is divided into two kinds, and 1 frequency hopping of Type is the uplink sent according to base station to terminal The specific tone hopping information of dispatch command UL (Up Link) grant carries out frequency hopping, in subframe corresponding with the UL grant, Frequency hopping, slot 1 do not carry out cyclic shift jump according to the specific tone hopping information of UL grant to slot 0 in available frequency hopping bandwidth Frequently.One specific example of Type1 frequency hopping as shown in Fig. 2, total bandwidth includes 50 RB (Resource Block, resource block), Wherein 6 RB are transmitted for PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel), are such as schemed 0~RB of RB 2 and 47~RB of RB 49, therefore can be 3~RB of RB 46 with frequency hopping bandwidth.UE1~UE4 (UE, User Equipment, user equipment) cyclic shift amount be 22 RB, 4 UE are in the not frequency hopping of slot 0, slot's 1 The frequency hopping that 22 RB of cyclic shift are realized in frequency hopping bandwidth can be used.
And 2 frequency hopping of Type is that the frequency hopping based on subband (subband) is carried out according to the specific frequency hop pattern of cell, Under 2 frequency-hopping mode of Type, all UE of the cell follow same frequency-hopping mode, the PUSCH (Physical for UE Uplink Shared Channel, Physical Uplink Shared Channel) transmission PRB (Physical RB, Physical Resource Block), be logical It crosses and the VRB (Virtual RB, virtual resource blocks) specified in UL grant is deviated what multiple subband were obtained, and in slot 0 and slot 1 has different offsets.One specific example of Type2 frequency hopping as shown in figure 3, can be with frequency hopping bandwidth RB 3~ RB 46 is divided into 4 subband, and each subband includes 11 RB, and the VRB that UE is assigned is 27~RB of RB 29, then It is 1 subband in 0 frequency hopping shift of slot by the mapping of VRB to PRB, is 3 subband in 1 frequency hopping shift of slot.
In addition, in traditional LTE system using only legacy TTI, base station issue terminal for carrying out uplink tune Degree instruction UL grant (wherein indicating information comprising ascending frequency-hopping) is only to a sub-frame of uplink corresponding with the UL grant (uplink legacy TTI) effectively, and using sTTI system in, in order to reduce the expense of Downlink Control Information, a UL Grant may correspond to the data transmission of a uplink sTTI of M (M > 1), i.e. base station sends a UL grant, terminal meeting to terminal According to the instruction of the UL grant, corresponding data modulating-coding is carried out in M uplink sTTI corresponding with this UL grant And resource impact etc., send upstream data.
