Description

Indicating means and base station, coding/decoding method and terminal that radio channel resource distributes

Technical field

The present invention relates to moving communicating field, particularly relate to indicating means and base station, coding/decoding method and terminal that a kind of radio channel resource distributes.

Background technology

LTE (Long Term Evolution, Long Term Evolution) system adopts the mode of base station centralized dispatching to control the Physical Uplink Shared Channel of user terminal (User Equipment, terminal) (Physical Uplink Shared Channel, PUSCH) transmission.

In the LTE system, the PUSCH frequency division multiplexing up-link bandwidth of a plurality of user terminals in the sub-district, promptly the PUSCH of different terminals is quadrature on frequency domain.And the base station is designated as the radio channel resource of the PUSCH distribution of certain terminal by uplink scheduling authorization signaling (Uplink Scheduling Grant abbreviates UL grant as).

It is unit that the uplink channel resources of LTE system distributes with the Resource Block.Resource Block is used to describe the mapping of physical channel (Physical Channel) to Resource Unit (Resource Element abbreviates RE as).Two kinds of Resource Block have been defined in the system: Physical Resource Block (Physical Resource Block abbreviates PRB as) and virtual resource blocks (Virtual Resource Block abbreviates VRB as).

A Physical Resource Block PRB accounts on frequency domain Individual continuous sub-carriers (subcarrier) accounts on time domain Individual continuous symbol.Wherein Subcarrier spacing is 15kHz, and promptly the width of a PRB on frequency domain is 180kHz.To regular circulation prefix (Normal cyclic prefix abbreviates Normal CP as),

To extended cyclic prefix (Extended cyclic prefix abbreviates Extended CP as),

Promptly the length of a PRB on time domain be a time slot (slot, 0.5ms).Like this, a PRB comprises

Individual Resource Unit.In a time slot, the index of PRB is n _PRB, wherein,

PRB number for up-link bandwidth correspondence; The index of RE to be (k, l), wherein,

Be the frequency domain index,

For the time Domain Index, then

With the regular circulation prefix is example, and the structure of PRB as shown in Figure 1.

A virtual resource blocks VRB has structure identical with PRB and size.Defined two types VRB, distributed VRB (Virtual resource blocks of distributed type) and centralized VRB (Virtual resource blocks of localized type).During resource allocation, a pair of VRB that is positioned on two time slots of a subframe (subframe) is distributed together, and a pair of VRB has an index n _VRB

Centralized VRB maps directly on the PRB, promptly

n _PRB＝n _VRB

Distributed PRB is mapped on the PRB, promptly according to certain rule

n _PRB＝f(n _VRB，n _s)

Wherein, n _s=0 ..., 19 is a radio frames (frame, 10ms) Nei time-gap numbers.VRB is different to the mapping of PRB on two time slots in a subframe.

As shown in Figure 2, the method for salary distribution of centralized (Localized) is adopted in the resource allocation of PUSCH, and promptly the PUSCH of a terminal occupies one section continuous bandwidth on frequency domain, is the part of whole up-link bandwidth.This section bandwidth comprises one group of continuous PRB, and the number of PRB is The continuous number of sub carrier wave that comprises is

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

One group of continuous VRB of terminal distribution is given by uplink scheduling authorization signaling UL grant in the base station.Particularly, be provide in the resource allocation territory (resource allocation field) at UL grant a resource indicatrix (Resource Indication Value, RIV).RIV indicates the original position RB of one group of continuous VRB by tree type method for expressing _STARTAnd length L _CRBs, wherein, RB _STARTFor this organizes the index of initial VRB among the continuous VRB, L _CRBsFor this organizes the VRB number that continuous VRB comprises.

LTE-Advanced system (being called for short the LTE-A system) is the evolution system of future generation of LTE system.As shown in Figure 3, the 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).A plurality of component carriers can be continuous, also can be discontinuous, can be positioned at same frequency range (band), also can be positioned at different frequency range.

In the LTE-A system, the PUSCH of certain user terminal in the one-component carrier wave can adopt continuous or discrete resource distribution mode according to the indication of system signaling.So-called continuous resource distributes, and promptly centralized resource distribution mode is meant that the PUSCH of user terminal occupies one section continuous bandwidth in the one-component carrier wave; So-called discontinuous resource allocation is meant that the PUSCH of user terminal occupies the multistage bandwidth in the one-component carrier wave, and these bandwidth are discontinuous, and every section bandwidth comprises one group of continuous PRB, is called cluster (cluster), as shown in Figure 4.

To the PUSCH of discontinuous resource allocation, how to indicate the channel resource that distributes, and save signaling consumption as much as possible by system signaling, become a problem demanding prompt solution.

The down channel resources of LTE system is assigned 3 kinds of modes, and type 0, type 1 and type 2, and wherein type 0 and type 1 are the unit allocation of channel resources may with Resource Block group (Resource Block Group abbreviates RBG as).RBG is defined as one group of continuous PRB, and the size of Resource Block group (RBG size, the PRB number that promptly comprises) is the function of system bandwidth.As shown in table 1, the LTE system bandwidth can be configured to 1.4MHz, 3MHz, and 5MHz, 10MHz, 15MHz, 20MHz, Dui Ying PRB number is 6,15,25,50,75,100 respectively.According to different system bandwidths

The size of Resource Block group is also different, i.e. the granularity of resource allocation (granularity) difference sees Table 2.

Table 1LTE system bandwidth

The size of table 2 Resource Block group

Propose in the research to the LTE-A system up-link, it is unit that the continuous resource branch in the one-component carrier wave is equipped with PRB, is unit but not the continuous resource branch is equipped with RBG.

During discontinuous resource allocation, the base station is distributed a plurality of discrete bunch by the uplink scheduling authorization signaling to user terminal, and each bunch comprises one group of continuous RBG.

In order to address the above problem, existing scheme is as follows:

Scheme 1:

System bandwidth is divided into some bunches, and every bunch comprises several continuous RBG, the mode of employing bitmap is indicated RBG in every bunch quantity and position.Allocative decision when the 25RB system bandwidth is divided two bunches as shown in Figure 5.

Scheme 2:

System bandwidth is divided into 2 bunches, and every bunch comprises several continuous RBG, lays respectively at the two ends, the left and right sides of system bandwidth, can have common factor between 2 bunches.Adopt the tree of type2 to carry out the resource allocation indication in every bunch.Terminal is known original position and the length information of the continuous RBG that is assigned with according to the resource allocation indication information of each bunch.As shown in Figure 6.During with the 5MHz system bandwidth 25RB for example, RBG size is 2RB, then is divided into 13 RBG, according to the tree-shaped indicating means of type2, as shown in Figure 7, by given RIV value as can be known bunch in the original position and the length of continuous RBG of distribution.

Scheme 3:

System bandwidth is divided into N bunch, and every bunch comprises several continuous RBG.By indicate every bunch, end bunch size and position that distribution is indicated in the RBG position.Especially, add two " virtual " RBG at the RBG front end of expression system bandwidth and represent that cluster has only the situation of 1 RBG.As shown in Figure 8, when system bandwidth 25RB, the start-stop position of adopting " beginning " " end " to represent bunch, two virtual locations of front end represent respectively whether the 1st bunch and the 2nd bunch had only 1 RBG.

Scheme one Resources allocation is more flexible, but owing to adopt the indicating mode of bitmap, the information bit that needs is a lot, can't carry out multiplexing with ascending resource assignment signalling among the LTE, must define several new signaling formats, the bigger lifting that brings terminal blind check number of times has limited the application of this kind 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 2 deficiencies are arranged.At first, it is 2 bunches that this scheme is divided system bandwidth, since every bunch of interval not exclusively coincidence of assignable system bandwidth, the shadow region that exists part not distribute, as shown in Figure 6.Secondly, for can and the ascending resource assignment signalling of LTE multiplexing, whether this scheme adopts the filling bit position in the LTE ascending resource assignment signalling to distinguish is discontinuous resource allocation, and the filling bit position only exists under part upstream and downstream bandwidth configuration scenario, so scheme two can not be distinguished continuous and discontinuous resource allocation fully.

The combined method of scheme three to bunch the position shadow region in the scheme two unrestrictedly and not can appear, but it also only could be multiplexing with the ascending resource assignment signalling of LTE when adopting filling bit to distinguish continuous and discontinuous resource allocation, same with scheme two, scheme three can not be distinguished continuous and discontinuous resource allocation fully.In addition, scheme three decodings are complicated, bring the part difficulty in the application.
