Radio Resource identical with another UE, and notify the of data that UE transmitted the first order of modulation in this Radio Resource
Several rank.
Preferably, module 34 is selected, for preferentially selecting the order of modulation of up-to-date registration less than the first modulation from resource
The resource of exponent number.
Preferably, module 34 is selected, for from treating extended resources pond to select order of modulation less than the resource of the first order of modulation,
Wherein, with extended resources pond for indicating that UE in cell is carried out adding up the UE less than threshold value for the use order of modulation obtaining by base station
Shared resource.
Fig. 4 is the structured flowchart two of data transmission device according to embodiments of the present invention, and this device is positioned in UE, comprising: send
Module the 42nd, receiver module 44 and processing module 46, illustrate to this structure below.
Sending module 42, for sending data transfer request to base station；Receiver module 44 is connected to sending module 42, is used for connecing
Receiving the notice of base station, wherein, notice is used for indicating that the Radio Resource that UE is used is identical with another UE, and indicates UE institute
Exponent number residing in first order of modulation in this Radio Resource for the data of transmission, wherein, the first order of modulation be base station according to
The corresponding order of modulation of shared data channel that the UE that the signal to noise ratio of the channel of UE obtains is used；Processing module 46 is connected to
Receiver module 44, is demodulated on the shared data channel for using first to demodulate exponent number, and the rank according to residing for transmission data
Number obtains corresponding bit, abandons remaining bit.
Certainly, may also provide a kind of data transmission system in the present embodiment, including above-mentioned base station and UE.
Below with reference to the accompanying drawings combine a preferred embodiment to illustrate.
In the preferred embodiment, Radio Resource distribution and the use way being modulated to basis with sublevel is provided, by difference noise
Use different hierarchical modulation unifications to carry out resource multiplex to Same Physical resource than the user under environment, thus effectively improve frequency
Utilization rate, thus improve the message capacity of system.The method comprises the steps:
Step S10, base station is added up according to the active situation of terminal use in this cell (i.e. user equipment), is found out it
Share data channel, for example, Physical Downlink Shared Channel (PDSCH), be currently in use the modulation system of more low order (for example,
BPSK/QPSK) terminal use.
Step S20, the Radio Resource shared by shared data channel being used this type of user equipment is chosen to be capacity and waits to extend
Radio Resource, and its current order of modulation is calculated as H1.
Step S30, new terminal user UE2 initiates data transmission requests, it is judged that the channel SNRs situation of UE2 present position,
Obtaining order of modulation Hx corresponding to shared data channel that UE2 uses, if Hx is ＞ H1, then the data transmission of UE2 can
Treat that extended wireless resource is transmitted to utilize.
Step S40, from treating to select a resource extended wireless resource pool, if its corresponding user is UE1, then will
The data of UE1 and UE2 are combined coded modulation.Preferably, this step can be divided into following steps to perform:
Step S401, selects the executable order of modulation of UE2, obtains the ratio corresponding to a symbol corresponding to this order of modulation
Special number Y.
Number of bits corresponding to original for a UE1 modulation symbol is X, remains stationary as, increase below by step S402
Y-X bit is then formed by the coded data of UE2.
Y the bit combining is carried out map modulation according to the order of modulation of UE2 by step S403.
Step S50, base station by control channel notification UE2, wireless shared by its currently used downlink shared data channel
Resource and UE1 are used identical (for example, identical RB number).And inform used resource is on which rank of order of modulation thereafter
(for example, for 64QAM modulation, then have 6 bits, then first is 1 rank, and second is second order, the three or four
Position is the 3rd rank, and the 5th 678 is fourth order (corresponding 256QAM)).
Step S60, UE1 is in normally receiving, and its original communication demodulation state need not change, i.e. UE1 continues according to former
First demodulation scheme is demodulated.During UE2 demodulation, after obtaining Y bit, according to oneself residing order of modulation, obtain phase
The bit answered, remaining information abandons.
Schematic diagram below in conjunction with system illustrates.Fig. 5 is the system schematic of application according to embodiments of the present invention, at Fig. 5
In the LTE system illustrating, each UE uses different RB (resource block Resource Block) to transmit data, a resource
Block is the resource of a time-frequency two-dimensional, have in time with the uniqueness in frequency.For example, now a LTE cell has
Several register UE, i.e. UE1, UE2......UEn, wherein have m UE to be active (wherein n ＞=m), account for
By all of RB resource in communication.Position is as shown in Figure 1 in the cell for it.Assume now all downlink resources by this m
Individual UE takies completely.Wherein, UE1, UE2, UE3 are owing at cell edge, signal to noise ratio ratio is relatively low, on PDSCH
The RB that they are used is respectively Ra, Rb, Rc, uses QPSK modulation, and other UE use 16QAM modulation.
It is the ratio modulation of lower-order (also 16QAM modulation system) owing to the QPSK of PDSCH channel is modulated in LTE,
ENodB (evolution base station) is by UE1, and RB:RBa that UE2, UE3 are used on PDSCH, RBb, RBc make
For treating that extended resources is recorded.Whenever having UE to use PDSCH and release PDSCH, just update a RB and wait to extend
The RB of release is deleted from table, the RB taking in low-order-modulated mode is added into list by resource situation table.
In the case that downlink resource has been fully loaded with, UE4, UE5 initiate suddenly data transfer request, are respectively necessary for RBx, RBy
Resource, can perform following steps in this case:
Step S701, it is judged that whether the signal link quality of UE4, UE5 meets the signal-noise ratio threshold of 16QAM modulation system
SNR_threshold.If SNR_ue4 is ＞=SNR_threshold, SNR_ue5 ＜ SNR_threshold, then from treating extension money
Source table allocates resources to meet the UE4 of signal to noise ratio condition, the resource distribution of refusal UE5.
Step S702, if treating extended resources amount R Ba+RBb+RBc ＜ Rx, then notifies that UE4 resource is inadequate.If
RBa+RBb+RBc ＞=Rx, then carry out following resource distribution.
Step S703, selects resource to be allocated according to the priority order of registration in treating extended resources list, and i.e. preferential distribution is up-to-date
The resource of registration.For example, the resource of the RBc shared by UE3 is finally registered, then select RBc resource to distribute to UE4.
From RBa+RBb+RBc Resource Block, according to above-mentioned rule, corresponding RB is distributed to UE4.If by shared by UE3
RB resource RBc is allocated to UE4, then can carry out following steps:
Step S801, the data of UE3 are taken out 2bit by eNodb, then the data of UE4 are taken out 2bit link together, such as figure
Shown in 6.
This 4bits data are modulated by step S802 as the modulation symbol of a 16QAM.If will be in a liter contrast system
After do not change the demodulation signal to noise ratio of UE3, need during modulation to keep on 16QAM (rising the modulation behind the rank) planisphere in Fig. 6
The shortest constellation distance between all quadrants in the shortest constellation distance between each quadrant and QPSK (original modulation) planisphere
Unanimously.It is i.e. all 2 in figure 6.Notifying UE4 on PDCCH, its data are in the second order position of 16QAM.
Step S803, UE3 still keeps its initial communication conditions as before, uses QPSK to receive on PDSCH.
Step S804, UE4 carries out 16QAM demodulation on PDSCH, by the 4bits corresponding to second order data i.e. each symbol
Latter two reservations.
By above-described embodiment, in the case that tradition LTE resource distribution can not complete, newly increase the communication of UE4, will be logical
The capacity boost of communication system.
