Description

A kind of channel resource allocation method and base station

Technical field

The present invention relates to moving communicating field, particularly relate to a kind of channel resource allocation method and base station.

Background technology

Third generation partner program (The 3rd Generation Partnership Project, abbreviate 3GPP as) Long Term Evolution (Long Term Evolution, abbreviating LTE as) system adopts the mode of base station centralized dispatching to control subscriber equipment (User Equipment, UE) Physical Uplink Shared Channel (Physical Uplink Shared Channel abbreviates PUSCH as) transmission.

In the LTE system, remove and adopt multi-user-MIMO technique (Multiple User-MultipleInput Multiple Output, abbreviate MU-MIMO as), the PUSCH frequency division multiplexing up-link bandwidth of different user devices in the sub-district, promptly the PUSCH of different UEs is quadrature on frequency domain.And base station (eNodeB abbreviates eNB as) is designated as the channel resource of the PUSCH distribution of certain UE by uplink scheduling authorization signaling (Uplink Scheduling Grant abbreviates UL grant as).

It is unit that the uplink channel resources of LTE system distributes with Resource Block (Resource Block abbreviates RB as).Resource Block is used to describe the mapping of physical channel (Physical Channel) to Resource Unit (ResourceElement abbreviates RE as).Two kinds of Resource Block have been defined in the system: Physical Resource Block (PhysicalResource Block abbreviates PRB as) and virtual resource blocks (Virtual Resource Block abbreviates VRB as).

A Physical Resource Block PRB accounts on frequency domain Individual continuous sub-carriers (subcarrier), wherein

Subcarrier spacing is 15kHz, and promptly the width of a PRB on frequency domain is 180kHz.

A Physical Resource Block PRB accounts for 1 time slot on time domain (slot 0.5ms), comprises

Individual continuous OFDM symbol, to regular circulation prefix (Normal cyclic prefix abbreviates NormalCP as),

To extended cyclic prefix (Extended cyclic prefix abbreviates Extended CP as),

Like this, a PRB comprises

Individual Resource Unit.In same time slot, the index of PRB is n _PRB, wherein,

PRB number for up-link bandwidth correspondence; The index of RE to be (k, l), wherein,

Be the frequency domain index,

For the time Domain Index, then

With the regular circulation prefix is example, and the structure of PRB as shown in Figure 1.

A virtual resource blocks VRB has structure identical with PRB and size.Defined two types VRB, distributed VRB (Virtual resource blocks of distributed type) and centralized VRB (Virtual resource blocks of localized type).During resource allocation, be positioned at a subframe (subframe, 1ms) a pair of VRB on interior two time slots is distributed together, a pair of VRB has an index n _VRB

Centralized VRB maps directly on the PRB, promptly

n _PRB＝n _VRB

Distributed PRB is mapped on the PRB, promptly according to certain rule

n _PRB＝f(n _VRB，n _s)

Wherein, n _s=0 ..., 19 is a radio frames (frame, 10ms) Nei time-gap numbers.VRB is different to the mapping of PRB on two time slots in a subframe.

As shown in Figure 2, in the LTE system, PUSCH adopts continuous resource to distribute (contiguous resourceallocation) mode, and promptly the PUSCH of a UE occupies one section continuous bandwidth on frequency domain, is the part of whole up-link bandwidth.This section bandwidth comprises one group of continuous PRB, and the number of PRB is

, the continuous number of sub carrier wave that comprises is

$M_{\mathrm{sc}}^{\mathrm{PUSCH}}=M_{\mathrm{RB}}^{\mathrm{PUSCH}}\·N_{\mathrm{sc}}^{\mathrm{RB}}$

The base station is distributed one group of continuous VRB by uplink scheduling authorization signaling UL grant to UE.Particularly, be provide in the resource allocation territory (resource allocation field) at UL grant a resource indicatrix (Resource Indication Value, RIV).RIV indicates the original position RB of one group of continuous VRB by tree type method for expressing _STARTAnd length L _CRBs, wherein, RB _STARTFor this organizes the index of initial VRB among the continuous VRB, L _CRBsFor this organizes the VRB number that continuous VRB comprises.RIV is calculated as follows.

If

$\mathrm{RIV}=N_{\mathrm{RB}}^{\mathrm{UL}}(L_{\mathrm{CRBs}}-1)+{\mathrm{RB}}_{\mathrm{START}}$

Otherwise

$\mathrm{RIV}=N_{\mathrm{RB}}^{\mathrm{UL}}(N_{\mathrm{RB}}^{\mathrm{UL}}-L_{\mathrm{CRBs}}+1)+(N_{\mathrm{RB}}^{\mathrm{UL}}-1-{\mathrm{RB}}_{\mathrm{START}})$

In the LTE system, the base station sends to target UE by Physical Downlink Control Channel (Physical Downlink ControlChannel abbreviates PDCCH as) with the uplink scheduling authorization signaling.LTE system definition multiple descending control information format (DCI format).Wherein, the uplink scheduling authorization signaling bear is in the PDCCH with descending control information format 0 (DCI format 0).In the PDCCH with DCIformat 0, the signaling consumption in resource allocation territory is

1bit frequency hopping flag bit (hopping flag) is used to indicate the PUSCH that is dispatched, and whether frequency hopping enables.

When PUSCH frequency hopping (frequencyhopping) when enabling, one group of continuous VRB of resource indicatrix RIV indication is mapped on the PRB according to certain frequency hopping rule, and VRB is different to the mapping of PRB on two time slots of the subframe of being dispatched.

When the PUSCH frequency hopping did not enable, one group of continuous VRB of resource indicatrix RIV indication mapped directly on the PRB.

In the LTE system, PDCCH receives the method that adopts blind Detecting.The time-frequency position UE possible at a class PDCCH attempts one by one to some kinds of PDCCH configurations, has identical descending control information format size (DCI format size, the payload that claims descending control information format again, the information bit and the filling bit number that comprise DCI format) PDCCH only need once to attempt, be called blind Detecting one time.

LTE-Advanced system (being called for short the LTE-A system) is the evolution system of future generation of LTE system.As shown in Figure 3, the LTE-A system adopts carrier aggregation (carrier aggregation) technological expansion transmission bandwidth, and the carrier wave of each polymerization is called one " component carrier " (component carrier).A plurality of component carriers can be continuous, also can be discontinuous, can be positioned at same frequency range (band), also can be positioned at different frequency range.

In the LTE-A system, the PUSCH on each component carrier independently dispatches.In the one-component carrier wave, the PUSCH of subscriber equipment can adopt the continuous resource method of salary distribution or discontinuous resource distribution mode (non-contiguous resource allocation) according to the indication of system signaling.So-called continuous resource distributes, and promptly as the LTE system, the PUSCH of subscriber equipment occupies one section continuous bandwidth in the one-component carrier wave; So-called discontinuous resource allocation is meant that the PUSCH of subscriber equipment in the one-component carrier wave occupies the multistage bandwidth, and these bandwidth are discontinuous, and every section bandwidth comprises one group of continuous RB, is called bunch (cluster) again, as shown in Figure 4.

Propose in the research to LTE-A system uplink channel resource distribution mode, it is unit that the continuous resource branch of PUSCH is equipped with RB, is unit but not the continuous resource branch is equipped with RBG, promptly uses for reference LTE system descending channel resource allocation mode, to save signaling consumption.

The down channel resources of LTE system is assigned 3 kinds of modes, and type 0, type 1 and type 2, and wherein type 0 is the unit allocation of channel resources may with Resource Block group (Resource Block Group abbreviates RBG as).RBG is defined as one group of continuous PRB, and the size of Resource Block group (RBG size, the PRB number that promptly comprises) is the function of system bandwidth.As shown in table 1, the LTE system bandwidth can be configured to 1.4MHz, 3MHz, and 5MHz, 10MHz, 15MHz, 20MHz, the PRB number of system bandwidth correspondence is respectively 6,15, and 25,50,75,100.According to different system bandwidths

, the size of Resource Block group is also different, i.e. and the granularity of resource allocation (granularity) difference sees Table 2.

In research, also propose LTE-A system uplink channel resource distribution mode:

The PUSCH of the discontinuous resource allocation of ■ is frequency hopping not;

■ bunch size (cluster size), promptly the RB number that comprises of cluster is N * 1RB or N * 2RBs or N * 3RBs or N * 4RBs or N * 5RBs, N is a natural number;

■ is for saving signaling consumption, and it is 2 that restriction divides number of clusters, and when promptly adopting discontinuous resource allocation, the PUSCH of a subscriber equipment occupies 2 sections discontinuous bandwidth in the one-component carrier wave, and every section bandwidth comprises one group of continuous RB, is called cluster.

The signaling consumption of the discontinuous resource allocation of ■ should be identical or close with the signaling consumption that continuous resource distributes, for

, wherein, to the continuous resource method of salary distribution,

Be the resource allocation territory, 1bit is the frequency hopping flag bit, thereby feasible carrying continuous resource distributes and the PDCCH of the uplink scheduling authorization signaling of the signaling of discontinuous resource allocation has identical DCI format size, and then does not increase the required blind Detecting number of times of UE reception PDCCH;

The resource allocation methods that prior art proposes not to bunch the ratio of length (perhaps size) make restriction.The modulation coding mode of considering each cluster data employing is identical, if the big or small gap of each bunch is too big, the channel estimating of each bunch also has bigger difference.

In the LTE system, the channel estimating of PUSCH is mainly finished by the demodulated reference signal DM RS that is used for PUSCH (Demodulation Reference Signal).

The DM RS structure of PUSCH as shown in Figure 5 and Figure 6.On the time domain, in each time slot, DM RS always is arranged in the 4th (l=3) of 7 Normal CP of this time slot symbol, or the 3rd (l=2) in 6 ExtendedCP symbols.On the frequency domain, UE sends the DM RS of PUSCH on the transmission bandwidth of its PUSCH.A predefined DM RS sequence r ^PUSCH() multiply by an amplitude zoom factor β _PUSCHAfter, from r ^PUSCH(0) beginning is mapped in the Resource Unit RE set identical with PUSCH transmission bandwidth position successively.To RE (k, l) when mapping, according to the order that k and l increase progressively, first frequency domain (k) back time domain (l) mapping.

The base station according to certain channel estimation method, obtains the channel response on the PUSCH transmission bandwidth after receiving demodulated reference signal DM RS, be used for the data demodulates of PUSCH on the corresponding frequency domain position.Channel estimating is accurate more, and the demodulation performance of PUSCH is good more.And accuracy of channel estimation, with DM RS sequence r ^PUSCHThe length of () is relevant, and is promptly relevant with the transmission bandwidth of PUSCH.DM RS sequence r ^PUSCH() is long more, and promptly the transmission bandwidth of PUSCH is wide more, and channel estimating is accurate more.

Prior art proposes, and in the LTE-A system, to adopting the PUSCH of discontinuous resource allocation, its demodulated reference signal DM RS adopts similar sending method, sends demodulated reference signal DM RS respectively on the transmission bandwidth that each bunch of PUSCH takies, as shown in Figure 7.

If then the big or small gap of each bunch is too big, correspondingly, the sequence length gap of the demodulated reference signal DM RS of each bunch correspondence is also very big, and the channel estimating of each bunch just has bigger difference, and then makes the demodulation performance of each cluster data also have than big-difference.

To sum up, to the PUSCH of discontinuous resource allocation, how to indicate the channel resource that distributes by system signaling, and save signaling consumption as much as possible, make it identical or close, limit the ratio of the size of each bunch simultaneously, become a problem demanding prompt solution with the signaling consumption of continuous resource distribution.
