Description

Large bandwidth system physical ascending control channel resource determining method and device

Technical field

The present invention relates to the communications field, in particular to a kind of large bandwidth system physical ascending control channel resource determining method and device.

Background technology

Fig. 1 is according to (the Long Term Evolution of the LTE in the correlation technique; Long Term Evolution) the frame structure sketch map of the FDD of system (Frequency Division Duplex, FDD) pattern is as shown in Figure 1; In the frame structure of fdd mode; The radio frame (radio frames) of a 10ms is 0.5ms by 20 length, and the slot (time slot) of numbering 0～19 forms, and it is subframe (subframe) i of 1ms that time slot 2i and 2i+1 form length.Fig. 2 is according to (the Long Term Evolution of the LTE in the correlation technique; Long Term Evolution) system TDD (Time Division Duplex; Time division duplex) the frame structure sketch map of pattern is as shown in Figure 2, in the frame structure of tdd mode; The radio frame (radio frames) of a 10ms is long for the halfframe of 5ms (field) forms by two, and field comprises 5 and longly is the subframe of 1ms (subframe).Subframe i is defined as 2 and longly is time slot 2i and the 2i+1 of 0.5ms.In two kinds of frame structures, for Normal CP (Normal Cyclic Prefix, standard cyclic prefix), the symbol that it is 66.7us that time slot comprises 7 length, wherein the CP length of first symbol is 5.21us, the CP length of all the other 6 symbols is 4.69us; For Extended (Extended, expansion) CP, a time slot comprises 6 symbols, and the CP length of all symbols is 16.67us.

LTE has defined PDCCH (Physical downlink control channel, Physical Downlink Control Channel) and has carried scheduling distribution and other control information; PCFICH (Physical control format indicator channel; Physical Control Format Indicator Channel) is carried on the information of number of the OFDM symbol that is used to transmit PDCCH in the sub-frame; On first OFDM symbol of subframe, send, the place frequency location is by system descending bandwidth and sub-district ID decision.Each PDCCH is made up of several CCE (Control Channel Element, control channel unit), and the CCE number of each subframe is by quantity and the downlink bandwidth decision of PDCCH.The CCE of each subframe according to first frequency domain after the serial number of time domain carry out index.

LTE Release-8 has defined 6 kinds of bandwidth: 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz and 20MHz.

LTE-Advanced (Further Advancements for E-UTRA) is the evolution version of LTE Release-8.Except that satisfying or surpassing 3GPP TR 25.913: all related needs of " Requirements for Evolved UTRA (E-UTRA) and Evolved UTRAN (E-UTRAN) ", also will meet or exceed the demand of the IMT-Advanced of ITU-R proposition.Wherein, the demand with the LTERelease-8 backward compatibility is meant: can work in the network of LTE-Advanced in the terminal of LTERelease-8; Can work in the network of LTE Release-8 in the terminal of LTE-Advanced.

In addition, LTE-Advanced should be able to comprise frequency spectrum configuration (like the continuous frequency spectrum resource of 100MHz) the down work wideer than LTE Release-8, to reach higher performance and target peak speed in the frequency spectrum configuration of different sizes.Because the LTE-Advanced network needs to insert LTE user, so its operational frequency bands need cover present LTE frequency band, on this frequency range, has not had the spectral bandwidth of assignable continuous 100MHz.So the direct technology that LTE-Advanced need solve is that several continuous component carrier frequency (frequency spectrum) (Component carrier) polymerizations that are distributed on the different frequency range are got up to form the operable 100MHz bandwidth of LTE-Advanced.Promptly for the frequency spectrum after assembling, be divided into n component carrier frequency (frequency spectrum) (Component carrier), the frequency spectrum in each component carrier frequency (frequency spectrum) is continuous.

Fig. 3 is the sketch map according to the configuration of the frequency spectrum in the correlation technique, and is as shown in Figure 3, and the scheme of frequency spectrum configuration mainly contains 3 kinds, and is as shown in Figure 3.Wherein, grid partly is the system bandwidth compatible with LTE Release-8, and oblique line partly is the proprietary system bandwidth of LTE-Advanced.Fig. 3 a is a frequency spectrum allocation plan 1, be meant that the LTE-Advanced frequency spectrum disposes the system bandwidth that is defined by 1 LTE-Advanced and forms, and this bandwidth is greater than the system bandwidth of LTE Release-8 definition.Fig. 3 b is a frequency spectrum allocation plan 2, is meant that LTE-Advanced frequency spectrum configuration is made up of through spectrum aggregation (carrier aggregation) the system bandwidth of a LTERelease-8 definition and the system bandwidth of a plurality of LTE-Advanced definition.Fig. 3 c is a frequency spectrum allocation plan 3; Be meant that the LTE-Advanced frequency spectrum disposes the system bandwidth that is defined by a plurality of LTE Release-8 and forms through spectrum aggregation (carrier aggregation); Wherein, The gathering of above-mentioned frequency spectrum can be the gathering of continuous frequency spectrum, also can be the gathering of discontinuous spectrum.LTE Release-8UE can insert the frequency band of compatible LTE Release-8, and LTE-A UE promptly can insert the compatible frequency band of LTE Release-8, also can insert the frequency band of LTE-Advanced.

Consider and the compatibility of LTE Release-8 that each component carrier frequency of LTE-Advanced all need satisfy can insert LTE user, this need guarantee to remain in the LTE unanimity at the channel architecture of each component carrier frequency as far as possible.

At present; LTE-Advanced is under the FDD dual-mode; The available component carrier frequency number of uplink and downlink can be different, and like this, each downlink component carrier frequency just can not corresponding one by one ascending control channel PUCCH (Physical uplink control channel; Physical Uplink Control Channel), the PUCCH resource index that designed of LTE just can't correctly be worked.

The PUCCH resource index at up transmission HARQ-ACK of dynamic dispatching PDSCH design is that the minimum CCE that distributes to this user's PDCCH on the descending sub frame through scheduling implies mapping under the LTE FDD dual-mode at present.Promptly

Wherein Be the PUCCH resource index that the user sends HARQ-ACK, n _CCEBe first CCE index of corresponding transmission PDCCH,

Dispose by high level.To the PDSCH of semi-persistent scheduling,

disposed by high level.

To the PDSCH of LTE TDD dual-mode dynamic dispatching, the PUCCH resource index of up transmission HARQ-ACK is that the CCE that distributes to this user's PDCCH on the descending sub frame through scheduling obtains through behind the block interleaving.Because tdd mode can exist down in the radio frames descending sub frame number more than the configuration of sub-frame of uplink number, so defined the notion of feedback window.The feedback window is corresponding all descending sub frames (need to prove that " correspondence " here is meant that these descending sub frames are all in this sub-frame of uplink feedback acknowledgment information) of sub-frame of uplink.

For the TDD dual-mode, owing to possibly exist in the radio frames descending sub frame greater than the configuration scene of sub-frame of uplink, so possibly exist the feedback information of a plurality of descending sub frames in same sub-frame of uplink, to send.The corresponding a plurality of descending sub frames of a sub-frame of uplink like this are called the feedback window.

Under TDD ACK/NACK binding or multiplexer mode; When the feedback window only was 1, definite method of

was:

Transmission is to be indicated by PDCCH for PDSCH; The perhaps transmission of the descending SPS release of PDCCH indication,

adopts and divides the block interleaving mapping to obtain.Transmission is not to be indicated by PDCCH for PDSCH; Then

is by high level configuration and table 1 decision; Table one shows the relation of the corresponding signaling of PUCCH resource index, shown in table one:

The relation of table one, the corresponding signaling of PUCCH resource index

For by Downlink Control Information (Downlink Control Information; Abbreviating DCI as) the semi-static descending scheduling of signaling indication activates transmission; Then indicates in high-rise four resources that dispose by the TPC territory, and the mapping form is provided by table one.

At present; In the continuous evolution process of LTE-Advanced; Support the demand of number of users to improve constantly to System Expansion, existing Physical Downlink Control Channel (Physical Downlink Control Channel abbreviates PDCCH as) can not satisfy the more requirement of advanced wireless communication system; 3GPP has introduced ePDCCH (Enhanced PDCCH under discussion for this reason; The PDCCH that strengthens) channel strengthens the PDCCH performance, introduces new transmission PDCCH zone simultaneously, at this moment; Physical Uplink Control Channel (Physical Uplink Control Channel the abbreviates PUCCH as) resource that how to obtain the corresponding transferring ACK/NACK of the PDSCH of ePDCCH is called problem demanding prompt solution.
