Description

A kind of definite method and device that disposes RBG size and numbering behind the burst carrier wave
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of definite method and device that disposes RBG size and numbering behind the burst carrier wave.
Background technology
Along with the development of Mobile Communication Industry and to the continuous growth of mobile data services demand, people are to speed and the service quality (QoS of mobile communication, Quality of Service) requirement is more and more higher, therefore before 3G (Third Generation) Moblie 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, the Long Term Evolution) project that third generation partner program starts.LTE system the highest available carrier bandwidths is 20MHz (megahertz), further evolution along with network, evolution LTE (LTE-A, LTE-Advanced) as the evolution system of LTE, carrier bandwidths up to 100MHz can be provided, support more flexible higher-quality communication, the LTE system possesses good backwards compatibility simultaneously.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 up-link carrier was spaced apart 15kHz, with subframe of time domain, 12 continuous or discrete subcarriers of frequency domain were as a Resource Block (RB, Resource Block).Whether RB is divided into two types of Physical Resource Block (PRB) and virtual resource blocks (VRB) 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.According to the difference of DCI type, also different to the indication of resource.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, and distinguish by resource dispensing head 1 bit this moment, 0 expression type, 0,1 expression Class1.And DCI form 1A, 1B, 1C, 1D then are used for the transmission of type 2.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:
1, DCI transmits by Class1,2,2A, 2B, 2C, and resource dispensing head bit value is 0:
Distribute in the type 0 in resource, resource block assignments information comprises a Resource Block set of dispense bitmap, and this Resource Block set of dispense bitmap represents that eNB distributes to the Resource Block group of particular UE (RBG, Resource Block Group) information; The big or small P of RBG depends on the carrier bandwidths of LTE system, and its corresponding relation is as shown in table 1:
Figure BDA0000088389570000021
Table 1
The number of resource group is common definite by carrier bandwidths and the resource group size of LTE system, namely Wherein comprise
Figure BDA0000088389570000023
Individual size is the resource group of P, and a size is
Figure BDA0000088389570000024
The Resource Block group, and the Resource Block group is from the low frequency open numbering, RBG numbers from 0 to N RBG-1 is mapped to respectively highest significant position to least significant bit.
2, DCI transmits by Class1,2,2A, 2B, 2C, and resource dispensing head bit value is 1:
Distribute in the Class1 in resource, resource block assignments information is the RB that a UE who is dispatched indicates distribution in the RBG subset range.This scheme is according to table 1 pair PRB grouping, contain P Physical Resource Block 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 the RBG subset range.
Distribute in the Class1 in resource, resource block assignments information is divided into 3 fields: first field is used
Figure BDA0000088389570000031
The position of the selected RB of individual bit labeling in RBG, second field uses 1 bit labeling whether to use skew, and the 3rd field comprises a 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:
Figure BDA0000088389570000032
Since the size of the method Bitmap less than
Figure BDA0000088389570000033
Therefore bitmap can't cover all RBG, when RBG is numbered, needs to use skew.In the resource block assignments information of the type, whether second field mark uses skew.This field is 0 o'clock, 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.This field is 1 o'clock, will be to introduce skew in the Resource Block numbering.The skew value is
Figure BDA0000088389570000034
Wherein
Figure BDA0000088389570000035
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:
3, DCI adopts resource to distribute type 2 by Class1 A, 1B, 1C, 1D transmission:
It is to adopt PRB to come indexed resource that resource is distributed type 0/1, and resource distributes type 2 to adopt VRB to indicate institute's Resources allocation.The benefit of employing VRB can adopt continuous dispensing when being exactly scheduling of resource, and then by local or distributed mode VRB is assigned to PRB, has also saved simultaneously the expense of signaling bit.
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 (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 having disposed the burst carrier wave, consider its characteristic: the resource of still indicating 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, cause occurring all different situations of RBG corresponding to carrier wave PRB quantity separately after backward compatibility carrier wave, burst carrier wave and the polymerization, 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 UE Resources 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.
