Description

A kind of determination method and device for configuring RBG sizes and numbering after burst carrier wave

Technical field

The present invention relates to wireless communication field, more particularly to a kind of determination for configuring RBG sizes and numbering after burst carrier wave Method and device.

Background technology

Development with Mobile Communication Industry and the continuous growth to mobile data services demand, people are to mobile logical The requirement more and more higher of the speed and service quality (QoS, Quality of Service) of letter, therefore in 3G (Third Generation) Moblie Before also without extensive commercialization, the research-and-development activity to next generation mobile communication system is just had begun to, wherein comparing More typical is Long Term Evolution (LTE, Long Term Evolution) project that third generation partner program starts.LTE systems Available highest carrier bandwidths of uniting are 20MHz (megahertz), with the further evolution of network, evolution LTE (LTE-A, LTE- Advanced) as LTE evolution system, up to 100MHz carrier bandwidths can be provided, are supported more flexible higher-quality Communication, while LTE system possesses good backwards compatibility.There are multiple component carrier (CC, Component in lte-a system Carrier), a LTE terminal can only operate on the CC of some backward compatibility, and the stronger LTE-A terminals of ability can be with It is transmitted simultaneously on multiple CC.

In LTE system, when up-link carrier is at intervals of 15kHz, by one subframe of time domain, the continuous or non-company of frequency domain 12 Continuous subcarrier is used as a resource block (RB, Resource Block).Whether RB is continuously divided into Physical Resource Block according to frequency (PRB) and virtual resource blocks (VRB) two types, it is the least resource unit of uplink and downlink scheduling.

Strengthen base station (eNB, enhanced Node B) carry out scheduling of resource when, by Downlink Control Information (DCI, Downlink Control Information) scheduling of resource situation is transferred to user equipment (UE, User Equipment). Transmission DCI physical channel is referred to as Physical Downlink Control Channel (PDCCH, Physical Downlink Control CHannel).UE explains the content of resource allocation field by PDCCH DCI types.According to the difference of DCI types, to money The instruction in source is also different.In each PDCCH, resource allocation field is made up of two parts:Resource allocation head and resource block distribute letter Breath.Resource allocation includes three types:Type 0, Class1 and type 2.Type 0 and Class1 use the bit number of identical quantity, When being transmitted by DCI Class1,2,2A, 2B, 2C, both possess identical form, now pass through first 1 ratio of resource allocation Spy distinguishes, and 0 represents that type 0,1 represents Class1.And DCI format 1A, 1B, 1C, 1D are then used for the transmission of type 2.Resource allocation Type 0/1 indicates resource using PRB, and resource allocation type 2 indicates distributed resource using VRB.

When eNB carries out scheduling of resource, there is following several situations:

1st, DCI is transmitted by Class1,2,2A, 2B, 2C, and resource allocation head bit value is 0:

In resource allocation type 0, resource block assignment information includes a resource block component coordination contour, the resource block component Coordination contour represents that eNB distributes to resource block group (RBG, Resource Block Group) information of particular UE;RBG size P Depending on the carrier bandwidths of LTE system, its corresponding relation is as shown in table 1:

Table 1

The number of resource group determines jointly by the carrier bandwidths and resource group size of LTE system, i.e., Wherein includeIndividual size is P resource group, and a size isResource block group, and resource Block group is numbered from 0 to N from low frequency open numbering, RBGRBG- 1 is respectively mapped to highest significant position to least significant bit.

2nd, DCI is transmitted by Class1,2,2A, 2B, 2C, and resource allocation head bit value is 1:

In resource allocation type 1, resource block assignment information is that the UE of a scheduled is indicated in RBG subset ranges The RB of distribution.The program is grouped according to table 1 to PRB, containing P Physical Resource Block in each RBG, by these resource blocks from 0 to P-1 is numbered, and chooses the physical resource composition RBG subsets that numbering is p in one section of continuous RBG, eNB is in RBG subset ranges It is interior that resource allocation is carried out to UE.

In resource allocation type 1, resource block assignment information is divided into 3 fields:First character section is usedIndividual ratio Selected positions of the RB in RBG of spy's mark, whether second field be using 1 bit labeling using skew, and the 3rd field includes one Individual bitmap, each bit of the bitmap is used to represent a PRB in selected RBG subsets.Resource block according to frequency growth It is mapped to since highest significant position on bitmap.The size of the bitmap is defined as:

Because the size of this method Bitmap is less thanTherefore bitmap can not cover all RBG, be carried out in RBG , it is necessary to use skew during numbering.In the resource block assignment information of the type, whether second field mark uses skew.The word When section is 0, Δshift(p)=0 without using skew, now the numbering of resource block is incremented by successively from zero since low-limit frequency.Should To be to introduce skew in resource block number when field is 1.Offseting value isWhereinThe RB quantity in subset of resource sets p is represented, can be obtained by equation below:

At UE ends, decoded by PDCCH, UE obtains the value of i-th of bit in bitmap, according to subset mark p, RB weight New definition is completed by equation below:

3rd, DCI is transmitted by Class1 A, 1B, 1C, 1D, using resource allocation type 2:

Resource allocation type 0/1 is that resource is indicated using PRB, and resource allocation type 2 is exactly to be indicated using VRB point With resource.Continuous dispensing can be used when using VRB benefit being exactly scheduling of resource, then again by local or distributed VRB is assigned to PRB by mode, while also saving the expense of signaling bit.

From table 1 it follows that the size of carrier bandwidths determines RBG size, and then determine resource allocation in DCI The number and the overall bit lengths of DCI of bit number.

Burst carrier wave (Carrier Segment) is a kind of carrier wave of incompatibility, and burst carrier wave can not be independently operated, only It can be used as a part for the bandwidth of a certain backward compatibility carrier wave, to increase the transmittability of backward compatibility carrier wave.Burst is carried Ripple with pairing backward compatibility carrier wave bandwidth sum no more than 110RBs (Carrier segments, If specified, are defined as the bandwidth extensions of a backwards compatible component carrier(no larger than 110RBs in total)and constitute a mechanism to utilize frequency resources in case new transmission bandwidths are needed in a backwards compatible way complementing carrier aggregation means)。

When being configured with burst carrier wave, it is contemplated that its characteristic:Increase after burst carrier wave still with a PDCCH come after indicating To compatible carrier wave and the overall resource of burst carrier wave.The addition of burst carrier wave can bring the increase of PRB sums, cause to occur backward The corresponding RBG of the respective PRB quantity of carrier wave all different situations, i.e. lowest version UE after compatible carrier wave, burst carrier wave and polymerization The RBG causes not of uniform size determined with the redaction UE for being configured with burst carrier wave according to PRB quantity.Because existing standard is not supported together When for two or more different RBG size UE distribute resource, therefore configuration burst carrier wave after, will face and how to determine RBG sizes, the problem of to be explicitly indicated resource allocation information.

The content of the invention

In view of this, it is a primary object of the present invention to provide after a kind of configuration burst carrier wave RBG sizes and number really Determine method and device so that redaction UE can more be convenient to use burst carrier wave, reduce burst carrier bandwidths to greatest extent For the influence of new system when smaller.
