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, UE) Physical Uplink Shared Channel (Physical UplinkShared 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 UEs 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 UE.

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 $N_{\mathrm{SC}}^{\mathrm{RB}}=12,$ 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), $N_{\mathrm{symb}}^{\mathrm{UL}}=7,$ To extended cyclic prefix (Extended cyclic prefix, referred to as Extended CP), $N_{\mathrm{symb}}^{\mathrm{UL}}=6,$ 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, $n_{\mathrm{PRB}}=0,...,N_{\mathrm{RB}}^{\mathrm{UL}}-1,$ N _rB ^uLfor the PRB number that up-link bandwidth is corresponding; The index of RE to being (k, l), wherein, $k=0,...,N_{\mathrm{RB}}^{\mathrm{UL}}{N}_{\mathrm{sc}}^{\mathrm{RB}}-1$ For frequency domain index, $l=0,...,N_{\mathrm{symb}}^{\mathrm{UL}}-1$ 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 UE 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

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

Base station distributes one group of continuous print VRB by uplink scheduling authorization signaling UL grant to UE.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, RB _sTARTfor 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.Signaling indicates original position and the final position of every cluster.Wherein, original position is expressed as the index of first RBG of every cluster, and final position is expressed as the index of last RBG of every cluster.Suppose that RBG number corresponding to the system bandwidth of one-component carrier wave is N, adopt discontinuous Resourse Distribute, frequency domain is divided into m bunch, first of every cluster and the position of last RBG need be indicated, then need indicate the position of 2m RBG in N number of RBG altogether.According to combinatorial formula, need

$\left(\begin{array}{c}N\\ 2m\end{array}\right)=\frac{N!}{(N-2m)!\·2m!}$

The state of kind.The example that Fig. 5 (1) is N=9, m=2.

It should be noted that the every cluster of said method requirement at least comprises 2 RBG, and can not represent that certain cluster or many bunches only comprise the situation of 1 RBG.For solving this problem, the basis of N number of RBG increases the individual virtual RBG of m, in 2m RBG of signaling instruction containing in the individual virtual RBG of this m some or multiple time, namely represent that certain corresponding cluster or many bunches only comprise 1 RBG, Fig. 5 (2) (3) (4) are N=9, three examples of m=2,2 the virtual RBG increased are respectively used to the situation that expression 2 bunches only comprises 1 RBG.Then need indicate the position of 2m RBG in N+2 RBG altogether, according to combinatorial formula, need

$\left(\begin{array}{c}N+2\\ 2m\end{array}\right)=\frac{(N+2)!}{(N+2-2m)!\·2m!}$

The state of kind.

There is following shortcoming in said method:

1) only give total status number, and do not provide indicating means corresponding to each state (each possible resource distribution location) and coding/decoding method;

2) divide number of clusters to be m, then need to increase m virtual RBG, there is the redundant state of some.Because bunch and bunch between be discrete, last RBG of front cluster and first RBG of lower cluster is non-conterminous, and from N or N+2 RBG, select arbitrarily 2m RBG to contain bunch and bunch between be continuous print situation.
