Description

The indicating means that radio channel resource distributes and base station, coding/decoding method and terminal
Technical field
The present invention relates to moving communicating field, particularly relate to indicating means and base station, coding/decoding method and the terminal of the distribution of a kind of radio channel resource.
Background technology
LTE (Long Term Evolution, Long Term Evolution) system adopts the mode of base station centralized dispatching to control user terminal (User Equipment, terminal) Physical Uplink Shared Channel (PhysicalUplink Shared Channel, PUSCH) transmission.
In LTE system, the PUSCH frequency division multiplexing up-link bandwidth of multiple user terminal in community, namely the PUSCH of different terminals is orthogonal on frequency domain.And the radio channel resource that base station is distributed by the PUSCH that uplink scheduling authorization signaling (Uplink Scheduling Grant, referred to as UL grant) is designated as certain terminal.
The uplink channel resources of LTE system distributes in units of Resource Block.Resource Block is for describing the mapping of physical channel (Physical Channel) to Resource Unit (Resource Element, referred to as RE).Two spike-type cultivars block is defined: Physical Resource Block (Physical Resource Block, referred to as PRB) and virtual resource blocks (Virtual Resource Block, referred to as VRB) in system.
A Physical Resource Block PRB accounts for N on frequency domain sC rBindividual continuous print subcarrier (subcarrier), time domain accounts for N symb uLindividual continuous print symbol.Wherein N SC RB = 12 , Subcarrier spacing is 15kHz, and namely the width of a PRB on frequency domain is 180kHz.To conventional cyclic prefix (Normal cyclic prefix, referred to as Normal CP), N symb UL = 7 , To extended cyclic prefix (Extended cyclic prefix, referred to as Extended CP), N symb UL = 6 , Namely the length of a PRB in time domain is a time slot (slot, 0.5ms).Like this, a PRB comprises N symb uL× N sC rBindividual Resource Unit.In one time slot, the index of PRB is n pRB, wherein, n PRB = 0 , . . . , N RB UL - 1 , N rB uLfor the PRB number that up-link bandwidth is corresponding; The index of RE to being (k, l), wherein, k = 0 , . . . , N RB UL N sc RB - 1 For frequency domain index, l = 0 , . . . , N symb UL - 1 For time Domain Index, then
For conventional cyclic prefix, the structure of PRB as shown in Figure 1.
A virtual resource blocks VRB has the structure identical with PRB and size.Define the VRB of two types, virtual reality B (Virtual resource blocks of distributed type) and centralized VRB (Virtual resource blocks of localized type).During Resourse Distribute, a pair VRB be positioned on a subframe (subframe) two time slots is distributed together, and a pair VRB has an index n vRB.
Centralized VRB maps directly on PRB, namely
n PRB＝n VRB
Distributed PRB is mapped on PRB according to certain rule, namely
n PRB＝f(n VRB，n s)
Wherein, n s=0 ..., 19 is the time-gap numbers in a radio frames (frame, 10ms).On two time slots in a subframe, the mapping of VRB to PRB is different.
As shown in Figure 2, the Resourse Distribute of PUSCH adopts the method for salary distribution of centralized (Localized), and namely the PUSCH of a terminal occupies one section of continuous print bandwidth on frequency domain, is a part for whole up-link bandwidth.This length of tape is wide comprises one group of continuous print PRB, and the number of PRB is M rB pUSCH, the continuous number of sub carrier wave comprised is
M sc PUSCH = M RB PUSCH · N sc RB
Uplink scheduling authorization signaling UL grant is passed through to terminal distribution one group of continuous print VRB in base station.Particularly, be provide a resource indicatrix (Resource Indication Value, RIV) in the Resourse Distribute territory (resource allocation field) of UL grant.RIV indicates the original position RB of one group of continuous VRB by tree-shaped method for expressing sTARTwith length L cRBs, wherein, R bSTARTfor the index of initial VRB in the continuous VRB of this group, L cRBsfor the VRB number that the continuous VRB of this group comprises.
LTE-Advanced system (abbreviation lte-a system) is the evolution system of future generation of LTE system.As shown in Figure 3, 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).Multiple component carrier can be continuous print, also can be discrete, can be positioned at same frequency range (band), also can be positioned at different frequency range.
In lte-a system, the PUSCH of certain user terminal in one-component carrier wave can adopt continuous or discrete resource distribution mode according to the instruction of system signaling.So-called continuous resource distributes, and namely centralized resource distribution mode, refers to that the PUSCH of user terminal occupies one section of continuous print bandwidth in one-component carrier wave; So-called discontinuous Resourse Distribute, refer to that the PUSCH of user terminal occupies multistage bandwidth in one-component carrier wave, these bandwidth are discrete, and every length of tape is wide comprises one group of continuous print PRB, is called cluster (cluster), as shown in Figure 4.
To the PUSCH of discontinuous Resourse Distribute, the channel resource how to be distributed by system signaling instruction, and save signaling consumption as much as possible, become a problem demanding prompt solution.
The down channel resources of LTE system is assigned 3 kinds of modes, type 0, type 1 and type 2, wherein type 0 and type 1 with Resource Block group (Resource Block Group, referred to as RBG) for unit allocation of channel resources.RBG is defined as one group of continuous print PRB, and the size (RBG size, the PRB number namely comprised) of Resource Block group is the function of system bandwidth.As shown in table 1, LTE system bandwidth can be configured to 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, 20MHz, and PRB number corresponding is respectively 6,15,25,50,75,100.According to different system bandwidth N rB dL, the size of Resource Block group is also different, and namely the granularity (granularity) of Resourse Distribute is different, in table 2.

Propose in the research to lte-a system up link, the continuous resource in one-component carrier wave divides that to be equipped with PRB be unit, but not continuous resource divides, and to be equipped with RBG be unit.
During discontinuous Resourse Distribute, base station distributes multiple discrete bunch by uplink scheduling authorization signaling to user terminal, and every cluster comprises one group of continuous print RBG.
In order to solve the problem, existing scheme is as follows:
Scheme 1:
System bandwidth is divided into some bunches, and every bunch comprises several continuous print RBG, adopts the mode of bitmap to indicate quantity and the position of RBG in every bunch.Allocative decision when 25RB system bandwidth divides two bunches as shown in Figure 5.
Scheme 2:
System bandwidth is divided into 2 bunches, and every bunch comprises several continuous print RBG, lays respectively at the two ends, left and right of system bandwidth, can there is common factor between 2 bunches.The tree of type2 is adopted to carry out Resourse Distribute instruction in every bunch.Terminal knows original position and the length information of the continuous RBG be assigned with according to the Resourse Distribute indication information of each bunch.As shown in Figure 6.With 25RB citing during 5MHz system bandwidth, RBG size is 2RB, be then divided into 13 RBG, according to the tree-shaped indicating means of type2, as shown in Figure 7, by original position and the length of the continuous RBG distributed in known bunch of given RIV value.
Scheme 3:
System bandwidth is divided into N number of bunch, and every bunch comprises several continuous print RBG.By indicate every bunch, only RBG position indicate bunch size and the position of distribution.Especially, representing that two " virtual " RBG are added to represent that cluster only has the situation of 1 RBG in the RBG front end of system bandwidth.As shown in Figure 8, when system bandwidth 25RB, adopt " beginnings " " end " expression bunch start-stop position, two virtual locations of front end represent whether the 1st bunch and the 2nd bunch only had 1 RBG respectively.
Scheme one Resources allocation is relatively more flexible, but owing to adopting the indicating mode of bitmap, the information bit of needs is a lot, cannot carry out multiplexing with ascending resource assignment signalling in LTE, the signaling format that several are new must be defined, bring the larger lifting of terminal blind check number of times, limit the application of this kind of scheme.
Scheme two is that the tree-shaped mapping of type2 is carried out in sub-clustering, and information bit consumption is less than scheme one, but has 2 deficiencies.First, this scheme dividing system bandwidth is 2 bunches, due to every bunch of interval not exclusively coincidence of assignable system bandwidth, and the shadow region that existence part can not be distributed, as shown in Figure 6.Secondly, in order to the ascending resource assignment signalling of energy and LTE is multiplexing, whether this scheme adopts the filling bit position in LTE ascending resource assignment signalling to distinguish is discontinuous Resourse Distribute, and filling bit position only exists under part upstream and downstream bandwidth configuration scenario, therefore scheme two can not distinguish continuous and discontinuous Resourse Distribute completely.
The combined method of scheme three to bunch position unrestricted and there will not be the shadow region in scheme two, but it also only could be multiplexing with the ascending resource assignment signalling of LTE when adopting filling bit to distinguish continuous and discontinuous Resourse Distribute, same with scheme two, scheme three can not distinguish continuous and discontinuous Resourse Distribute completely.In addition, scheme three is decoded more complicated, brings the part difficulty in application.
