Description
Technical field
The present invention relates to the communications field, be specifically related to a kind of Resource Block group (RBG, Resource Block Group) processing method and system.
Background technology
Along with the development of Mobile Communication Industry and to the continuous growth of mobile data services demand, people are more and more higher to the requirement of the speed of mobile communication and service quality (Qos), so before 3G (Third Generation) Moblie (3G) does not also have extensive commercialization, just begun the research-and-development activity to next generation mobile communication system, wherein relatively be typically Long Term Evolution (LTE) project that third generation partner program (3GPP) starts, the available maximum spectrum bandwidth of LTE system is 20MHz (megahertz).Along with the further evolution of network, LTE-A (evolution LTE) can provide the spectral bandwidth up to 100MHz as the evolution system of LTE, supports more flexible higher-quality communication, and possesses good backwards compatibility.A plurality of component carriers (CC, component carrier) are arranged in the LTE-A system, and a LTE terminal can only be operated on the CC of some backward compatibility, and the stronger LTE-A terminal of ability can be transmitted at a plurality of CC simultaneously.
In the LTE system, when subcarrier spacing is 15kHz, with 12 continuous or discrete subcarriers on a subframe on the time domain, the frequency domain as a RB (Resource Block, Resource Block).Whether RB is divided into PRB (Physical Resource Block) and two kinds of type of VRB (virtual resource blocks) (type) continuously according to frequency, is the least resource unit of uplink and downlink scheduling.
Strengthen base station (eNB, enhanced Node B) when carrying out scheduling of resource, (DCI, Downlink Control Information) is transferred to subscriber equipment (UE, User Equipment) with the scheduling of resource situation by Downlink Control Information.The physical channel of transmission DCI is called Physical Downlink Control Channel (PDCCH, Physical Downlink Control CHannel).UE explains the content of resource allocation field by the DCI type of PDCCH.Among each PDCCH, resource allocation field is comprised of two parts: resource dispensing head and resource block assignments information.Resource is distributed and is comprised three types: type 0, Class1 and type 2.Type 0 and Class1 use the bit number of equal number, and by DCI Class1,2,2A, 2B, 2C transmission the time, both have identical form; At this moment, distinguish 0 expression type, 0,1 expression Class1 by resource dispensing head 1 bit.DCI form 1A, 1B, 1C, 1D then are used for type 2 transmission.Resource distributes type 0/1 to adopt PRB to come indexed resource, and resource distributes type 2 to adopt VRB to indicate institute's Resources allocation.
When eNB carries out scheduling of resource, there are following several situations:
DCI is by Class1,2,2A, 2B, 2C transmission, and the bit value of resource dispensing head (Resource Allocation Header) is 0 o'clock:
Distribute in the type 0 in resource, resource block assignments information comprises the set of resources coordination contour, and this bitmap represents that eNB distributes to the RBG information of particular UE.The big or small P of RBG depends on system bandwidth, and its corresponding relation is as shown in table 1, and table 1 is that the resource of 3GPP version 10 (Release-10) definition is distributed RBG size and downlink system bandwidth mapping table:
Table 1
The number of resource group is common definite by system bandwidth and resource group size:
Wherein comprise
Individual size is the resource group of P, and a size is
The resource group.The resource group is from the low frequency open numbering.The RBG numbering is from 0 to N
RBG-1 is mapped to respectively highest significant position to least significant bit.
DCI is by Class1,2,2A, 2B, 2C transmission, and the bit value of resource dispensing head is 1 o'clock:
Distribute in the Class1 in resource, resource block assignments information is the RB that a UE who is dispatched indicates distribution in the RBGs subset range.This scheme contains P Physical Resource Block according to table 1 pair PRB grouping among each RBG.These Resource Block are numbered from 0 to P-1.Choose the physical resource that is numbered p among one section continuous RBG and form the RBG subset.ENB carries out resource to UE and distributes in subset range.
In Class1, resource block assignments information is divided into 3 fields:
First field is used
The position of the selected RB of individual bit labeling in RBG;
Second field uses 1 bit labeling whether to use skew;
The 3rd field comprises bitmap, and each bit of this bitmap is used for a PRB of the selected RBG subset of expression.Resource Block begins to be mapped on the bitmap from highest significant position according to the growth of frequency.The size definition of this bitmap is:
Since bitmap less than
Therefore bitmap can't cover all RBG, causes RBG need to be offset when being numbered.
When second field that marks whether to use skew is 0, Δ
Shift(p)=0 do not use skew.The numbering of Resource Block increases progressively successively from zero from low-limit frequency at this moment.Described second field is 1 o'clock, will introduce skew when Resource Block is numbered, and the skew value is:
Wherein
RB quantity in the expression resource group subset p.
Can obtain by following formula:
At the UE end, by the PDCCH decoding, UE obtains the value of i bit in the bitmap, and according to subset sign p, reorientating by following formula of RB finished:
DCI adopts resource to distribute type 2 by Class1 A, 1B, 1C, 1D transmission.Resource distributes type 0/1 to adopt PRB to come indexed resource, and resource distributes type 2 to adopt VRB to indicate institute's Resources allocation.
As can be seen from Table 1, the size of carrier bandwidths has determined the size of RBG, and then has determined the bit length of what and DCI integral body of resource allocation bit number among the DCI.
Burst carrier wave (Carrier Segment) is a kind of carrier wave of incompatibility, and the burst carrier wave can not independently use, and can only use as the part of the bandwidth of a certain backward compatibility carrier wave, to increase the transmittability of backward compatibility carrier wave.The bandwidth sum of the backward compatibility carrier wave of burst carrier wave and pairing is no more than 110RBs.
When having disposed the burst carrier wave, consider its characteristic (still indicating the resource of backward compatibility carrier wave and burst carrier wave integral body behind the increase burst carrier wave with a PDCCH), the burst carrier wave add the affiliation bring the PRB sum increase, all different situations of RBG corresponding to carrier wave PRB quantity separately after backward compatibility carrier wave, burst carrier wave and the polymerization may appear, i.e. lowest version UE and disposed not of uniform size the causing of RBG that the redaction UE of burst carrier wave determines according to PRB quantity.Because existing standard does not support to be simultaneously the user resource allocation of two or more different RBG sizes, so after disposing the burst carrier wave, will face how to confirm RBG size, with the problem of clear and definite indexed resource assignment information; Because the existence of above-mentioned RBG situation about causing not of uniform size, described problem can't solve at present but obviously.

After determining RBG size corresponding to each carrier wave, the RB of burst carrier wave and backward compatibility carrier wave is considered as two independently parts, divides RBG according to RBG size separately respectively, and can not contain simultaneously the RB of backward compatibility carrier wave and burst carrier wave in RBG.If the RB sum is not the integral multiple of RBG size, then continue to use 3GPP Release-10 regulation: the RB quantity that comprises in the RBG of numbering maximum can be less than the RBG size.
The rule of RBG numbering is: for the RBG of backward compatibility carrier wave, continue to use 3GPP Release-10 regulation from 0 open numbering; For the RBG of burst carrier wave, from the maximum of the RBG of backward compatibility carrier wave numbering, continue numbering, number order can be from the low frequency to the high frequency, or from the high frequency to the low frequency.Here continue to use the 3GPPRelease-10 regulation, from the low frequency to the high frequency, number.As shown in Figure 1, the RBG of backward compatibility carrier wave numbering from 0 to 12 (1 RB that wherein only comprises the backward compatibility carrier wave the 12nd RBG), the RBG numbering from 13 to 15 of burst carrier wave.When indication RBG distribution condition, continue to use the resource distribution type 0,1 among the 3GPP Release-10,2 working method, dissimilar and RBG corresponding to carrier wave bandwidth varies in size.

The rule of RBG numbering is: for the RBG of backward compatibility carrier wave, continue to use 3GPP Release-10 regulation from 0 open numbering; For the RBG of burst carrier wave, continue to use 3GPP Release-10 regulation from 0 open numbering, number order can be from the low frequency to the high frequency, or from the high frequency to the low frequency.Here continue to use the 3GPPRelease-10 regulation, from the low frequency to the high frequency, number.As shown in Figure 2, the RBG of backward compatibility carrier wave numbering from 0 to 12 (1 RB that wherein only comprises the backward compatibility carrier wave the 12nd RBG), the RBG numbering from 0 to 5 of burst carrier wave.When indication RBG distribution condition, continue to use the resource distribution type 0,1 among the 3GPP Release-10,2 working method, dissimilar and RBG corresponding to carrier wave bandwidth varies in size, and the RBG numbering may repeat after the dissimilar carrier aggregation, therefore need the newly-increased DCI form that comprises the carrier wave indicating bit, be used to indicate affiliated backward compatibility carrier wave and the burst carrier wave of resource of scheduling.
Can suppose that the carrier wave indicating bit is 2 bits, be positioned at the front two of resource indicating bit, the backward compatibility carrier index is 0, and the burst carrier index is 1.When adopting so resource to distribute type 0, call the RBG 1,5,12 resource allocation bit corresponding with the RBG 2 of burst carrier wave of backward compatibility carrier wave as shown in Figure 3.According to the resource allocation bit that comprises among the DCI, UE can know the RBG 1,5 that called on the backward compatibility carrier wave, 12 and the burst carrier wave on RBG 2, can table look-up according to bandwidth again simultaneously and know that RBG size corresponding to backward compatibility carrier wave is 2, the RBG size that the burst carrier wave is corresponding is 1, therefore can clearly know resource allocation conditions.
In conjunction with above each embodiment as can be known, the operation thinking that the present invention processes RBG can represent flow process as shown in Figure 4, and this distance may further comprise the steps:
Step 410: burst carrier wave and the backward compatibility carrier wave that uses that will match is considered as two independently parts, determines that according to bandwidth separately RBG separately is big or small respectively.
