Technical field

The present invention relates to the communications fields, in particular to a kind of enhancing physical hybrid automatic repeat request indicator channel The transmission method and dress of (enhanced Physical Hybrid ARQ Indicator Channel, referred to as ePHICH) It sets.

Background technique

Long term evolution (Long Term Evolution, referred to as LTE) system is third generation partnership (3rd Generation Partnership Project, referred to as 3GPP) essential planning.LTE system uses conventional cyclic prefix It include the uplink/downlink symbol of 7 length when (Cyclic Prefix, referred to as CP), in a time slot；LTE system is using extension It include the uplink/downlink symbol of 6 length when CP, in a time slot.

Following several physical channels are defined in LTE system:

Physical Broadcast Channel (Physical Broadcast Channel, referred to as PBCH): the information of the channel bearing Include: the frame number of system, the downlink bandwidth of system, physical mixed retransfer channel period and for determine physical mixed from Dynamic retransmission request indicates channel (Physical Hybrid ARQ Indicator Channel, referred to as PHICH) channel group number Parameter N_g∈ { 1/6,1/2,1,2 }；

Physical Multicast Channel (Physical Multicast Channel, referred to as PMCH): it is mainly used for supporting multicast Single Frequency Network (Multicast Broadcast over Single Frequency Network, referred to as MBSFN) business, Multimedia time-frequency information is broadcasted to multi-user.PMCH can only be in MBSFN sub-frame and MBSFN area transmissions；

Physical Downlink Shared Channel (Physical Downlink Shared Channel, referred to as PDSCH): for holding Carry downlink transmission data；

Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as PDCCH): it is used for Carry uplink and downlink scheduling information and uplink power control information.PDCCH in LTE R8, R9 and R10 is mainly distributed on Preceding 1,2,3 or 4 orthogonal frequency division multiplexing (Orthogonal Frequency Division of one subframe Multiplexing, referred to as OFDM) symbol, specific distribution needs are according to different subframe type and public reference signal The port number of (Common Reference Signal or Cell-specific Reference Signal, referred to as CRS) To configure.As shown in table 1, the downlink resource block of the port number configuration according to different subframe type and CRS is set forth NumberThe OFDM symbol number that PDCCH greater than 10 and no more than 10 is occupied；

The OFDM symbol number that table 1PDCCH is occupied

Physical Control Format Indicator Channel (Physical Control Format Indicator Channel, referred to as PCFICH): the information of carrying is used to indicate the number that the OFDM symbol of PDCCH is transmitted in a subframe, the first of subframe It is sent in a OFDM symbol, place frequency location is determined by system descending bandwidth and cell ID (Identity, referred to as ID)；

PHICH: for carrying acknowledgement/non-acknowledgement (ACK/NACK) feedback information of uplink transmission data.PHICH Number, time-frequency location can be as Physical Broadcast Channel (the Physical Broadcast of the descending carrier where PHICH Channel, referred to as PBCH) in system message and cell ID determine；

Physical uplink Data Shared Channel (Physical Uplink Shared Channel, referred to as PUSCH), is used for Carry uplink transmission data.

The transmission of LTE physical layer PHICH channel comes tissue, multiple PHICH in 1 PHICH group in the form of PHICH group The identical time-frequency domain physical resource of channel occupancy, using the multiplex mode of orthogonal spreading sequence.In conventional cyclic prefix (Normal Cyclic Prefix, referred to as Normal CP) in the case where, use spreading factor to combine I/Q (In-phase/ for 4 Quadrature, inphase quadrature) two-way BPSK (Binary Phase Shift Keying, binary phase shift keying) modulation Multiplex mode includes 12 modulation symbols in 1 PHICH group, occupies 3 resource unit group (Resource Element Group, referred to as REG), it is multiplexed 8 PHICH channels.In extended cyclic prefix (Extended Cyclic Prefix, abbreviation When for Extended CP), for the stronger wireless channel of frequency selectivity, spreading factor is used to combine I/Q two-way BPSK for 2 The multiplex mode of modulation includes 6 modulation symbols in 1 PHICH group, is multiplexed 4 PHICH channels, at this point, 2 PHICH groups are total to With the physical resource for occupying 3 REG.

On frequency domain, corresponding 3 REG of 1 PHICH group use distributed mapping mode, to obtain diversity gain.? On time, there is conventional and extension two kinds of resources mapping mode in the PHICH duration (PHICH duration).In usual manner When, PHICH is mapped in first OFDM symbol of subframe；And work as Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as PDCCH) length be 3 when (either in the MBSFN sub-frame of mixed carrier or time division duplex In (Time Division Duplex, referred to as TDD) special subframe, when PDCCH length is 2), PHICH is configurable to expand The mode of exhibition, PHICH will be distributed in the occupied multiple OFDM symbols of PDCCH at this time.

In LTE, led using public reference signal (Specific Reftrence Signals, referred to as CRS) The measurement and demodulation of frequency, i.e., all users use CRS to carry out channel estimation.Transmitting terminal is needed additionally to lead to when using this CRS Know specific pretreatment mode used by the data that receiving end is emitted, and the expense of pilot tone is larger.In addition in multi-user In multiple-input and multiple-output (Multi-user Multi-input Multi-output, referred to as MU-MIMO), due to multiple ends End uses identical CRS, cannot achieve the orthogonal of pilot tone, therefore be unable to estimate interference.In LTE-A, opened to reduce pilot tone Pin, respectively defines two class reference signals: and demodulated reference signal (Demodulation Reference Signal, referred to as DMRS) and channel state information reference signals (Channel State Information Reference Signal, referred to as CSI-RS), wherein demodulation of the DMRS for PDSCH.For channel state information (Channel State Information, letter Referred to as CSI) measurement CSI-RS, be mainly used for channel quality instruction (Channel Quality Indicator, referred to as CQI), pre-coding matrix instruction (Precoding Matrix Indicator, referred to as PMI), order instruction (Rank Indicator, referred to as RI) etc. information report.Also it is referred to as zero power comprising a kind of special CSI-RS signal in CSI-RS Rate channel state information reference signals (Zero Power Channel State Information Reference Signal, Referred to as ZP-CSI-RS), it is confirmed as not sending any reference signal sequence or data in the resource for ZP-CSI-RS, it is no Then it is referred to as non-zero power channel state information reference signals (Non-Zero Power Channel State Information Reference Signal, referred to as NZP-CSI-RS) signal.The effect of ZP-CSI-RS is primarily to more accurately measure Adjacent area interference.

Fig. 1 is the schematic diagram of LTE system Physical Resource Block (Resource Block, referred to as RB).As shown in Figure 1, one A resource element (Resource Element, referred to as RE) is a subcarrier in an OFDM symbol, and a downlink RB is made of continuous 12 subcarriers and 7 continuous (being 6 when extended cyclic prefix) OFDM symbol.One resource Block is 180kHz on frequency domain, is the time span of a time slot in time domain.It, can be (right with a subframe when carrying out resource allocation Answer two time slots) on two resource blocks (also referred to as Physical Resource Block to) be basic unit to be allocated.Fig. 2 is LTE system It unites the schematic diagram of Physical Resource Block pair, the resource location of corresponding PDCCH, CRS and DMRS etc. is also shown in Fig. 2.

Under LTE-A heterogeneous network, since there are strong interferences between different types of base station, it is contemplated that macro base station (Macro ENodeB) to the interference problem of micro-base station (Pico), propose using the method for resource silence solve different type base station it Between interfere with each other problem, specific resource silence method can be divided into: silence (Muting) method based on subframe is (such as empty The method of subframe (Almost Blank Subframe, referred to as ABS)) and silent method (such as CRS based on resource element Silent method).The existing method using resource silence solves the problems, such as the method interfered with each other between different type base station, no But the waste of resource is increased, and brings great limitation for scheduling, is especially matched in the ABS of consideration Macro eNodeB When setting, if the distribution of Pico is more, the ABS of Macro eNodeB configuration is more, brings to Macro eNodeB biggish It influences, increases scheduling delay while increasing the wasting of resources；Although moreover, can be reduced at ABS for control channel The interference of different control channel data resources, but the interference problem of CRS resource and data resource can not be solved, for silence The method of CRS can not solve the interference between data resource.In addition, this method backwards compatibility is bad, access delay is increased While, it may be necessary to more standardization efforts.

More users may be introduced in the LTE R11 stage to send in MBSFN sub-frame, will will lead in this way MBSFN configures the off-capacity for the down control channel that 2 OFDM symbols can carry, in order to guarantee to R8/R9/R10 user Backwards compatibility, need to open up the resource of new transmission control information in PDSCH resource, and introduce in the R11 stage Coordinated multipoint transmission (Coordinated Multiple Point Transmission and Reception, referred to as CoMP) technology, this technology can solve the interference problem between different type cell by way of space division, and save Resource overhead avoids the silent bring wasting of resources, reduces the limitation to scheduling.But according to conventional Time-domain downlink control The mode of channel processed is can not to solve this problem by the method for space division.

In the LTE R11 stage by the enhancing to PDCCH, i.e., a part of resource is marked off in original PDSCH region Transmit enhancing Physical Downlink Control Channel (enhanced Physical Downlink Control Channel, referred to as EPDCCH), the capacity and the number of scheduling user's set simultaneously of PDCCH thus can be improved, wherein ePDCCH is by enhancing Physical control channel unit (enhanced Control Channel Element, referred to as eCCE) composition, and each eCCE Be again by multiple enhancing resource element groups (enhanced Resource Element Group, referred to as eREG) form, and The Physical Resource Block of ePDCCH is each distributed to being divided into each PRB (Pyhsical under 16 eREG, such as routine CP Resource Block, physical resource are fast) the eREG division mode of centering is as shown in Figure 3.

In LTE R12, due to new carrier type (New Carrier Type, referred to as NCT) and cell (small Cell introducing), traditional downlink physical control channel region will be excluded, and carry out physical down control letter based on ePDCCH The transmission of order, this results in existing PHICH design that can not be suitable for new frame structure.In addition it in Low cost MTC, needs Support small bandwidth reception technique, but since conventional Time-domain down control channel mode is to be dispersedly distributed control channel information On full bandwidth, therefore small bandwidth can not be supported to receive well.

Therefore, for capacity problem existing for above-mentioned tradition PHICH, interference problem and NCT and Low cost MTC The problem that can not be applicable in scape needs to consider the physical down HARQ instruction channel of enhancing.At present about the physical down of enhancing The design problem of HARQ instruction channel is not yet put forward effective solutions.
