Description

The method of sending and receiving of ePHICH and system

Technical field

The application relates to the communication technology, particularly relates to the method for sending and receiving and system that strengthen physical mixed repeat requests indicating channel (ePHICH).

Background technology

In evolution Universal Terrestrial wireless access (E-UTRA) system of third generation partner program (3GPP), the sending/receiving of data supports hybrid automatic repeat-request (HARQ) technology, to reduce data transmission delay and to obtain higher message transmission rate.In HARQ technology, data receiver needs to data receiver feedback acknowledgment/deny (ACK/NACK) information, confirms that data receiver correctly receives to help data receiver.

In the down link direction of LTE, base station (such as, eNodeB) by the ACK/NACK information of downlink physical mixing repeat requests verification indicating channel (PHICH) to subscriber equipment (UE) feeding back uplink data receiver, namely base station (such as, eNodeB) to its whether the data transmission block correctly received from UE send ACK/NACK information to UE.

Long Term Evolution (LTE)/senior Long Term Evolution (LTE-A) system is the essential planning of third generation partnership 3GPP.

The transmission of LTE physical layer PHICH channel is organized with the form of PHICH group, the time-frequency domain physical resource that the multiple PHICH channel occupancies in 1 PHICH group are identical, the multiplex mode of secondary orthogonal spreading sequence.When conventional cyclic prefix (CP), adopt spreading factor to be 4 multiplex modes modulated in conjunction with I/Q two-way BPSK, 1 PHICH group comprises 12 modulation symbols, takies 3 resource element groups (REG), multiplexing 8 PHICH channels.When expanding CP, for the wireless channel that He Ne laser is stronger, spreading factor is adopted to be 2 multiplex modes modulated in conjunction with I/Q two-way BPSK, 1 PHICH group comprises 6 modulation multiplex, multiplexing 4 PHICH channels, now, 2 PHICH groups take the physical resource of 3 REG jointly.

Fig. 1 is the schematic diagram of the LTE system Physical Resource Block (RB) of prior art.As shown in Figure 1, resource element (RE) is a subcarrier in an OFDM symbol, and a descending RB is made up of continuous print 12 subcarriers and continuous print 7 (when extended cyclic prefix being 6) OFDM symbol.A Resource Block is 180kHz on frequency domain, time domain is the time span of a time slot.When carrying out Resourse Distribute, can with in a subframe (corresponding two time slots) two Resource Block (also referred to as Physical Resource Block to) distribute for base unit.

Fig. 2 is the schematic diagram that the time-frequency domain of the PHICH channel of prior art maps, and as shown in Figure 2, on frequency domain, 3 REG of 1 PHICH group correspondence adopt distributed mapping mode, to obtain diversity gain; And in time, PHICH has conventional and expansion two spike-type cultivars mapping mode.When usual manner, PHICH is mapped on first OFDM (OFDM) symbol of subframe; And when the length of Physical Downlink Control Channel (PDCCH) is 3, in the MBSFN sub-frame or time division duplex (TDD) special subframe of mixed carrier, when PDCCH length is 2, PHICH can be configured to the mode expanded, and now PHICH is by multiple OFDM symbol of being distributed in shared by PDCCH.

In LTE, adopt public reference signal (CRS) to carry out pilot measurement and demodulation, CRS is the specific reference signal in community, and in Ji Yige community, all users use CRS to carry out channel estimating.Adopt the concrete pretreatment mode that the data needing transmitting terminal additional notifications receiver side to launch during this CRS have employed, and the expense of pilot tone is larger.In addition in multi-user's multiple-input and multiple-output (MU-MIMO), because multiple terminal uses identical CRS, the orthogonal of pilot tone cannot be realized, be therefore unable to estimate interference.In LTE-A, in order to reduce pilot-frequency expense, respectively define two class reference signals: demodulated reference signal (DMRS) and channel state information reference signals (CSI-RS).DMRS and CSI-RS is the specific reference signal of user (UE), DMRS is mainly used in the demodulation of the Physical Downlink Control Channel (ePDCCH) of Physical Downlink Shared Channel (PDSCH) and enhancing in the prior art, wherein DMRS antenna port 7 ~ 14 is for PDSCH demodulation, DMRS antenna port 107 ~ 110 is for ePDCCH demodulation, Fig. 3 is DMRS antenna port (7 ~ 14) resource pattern relevant to PDSCH transmission under conventional CP, Fig. 4 is DMRS antenna port (7 ~ 14) resource pattern relevant to PDSCH transmission under expansion CP, Fig. 5 transmits relevant DMRS antenna port (107 ~ 110) resource pattern under conventional CP to ePDCCH, Fig. 6 transmits relevant DMRS antenna port (107 ~ 110) resource pattern to ePDCCH under expansion CP.CSI-RS is mainly used in the measurement of channel condition information (CSI) and channel quality indicates (CQI), pre-coding matrix instruction (PMI), order indicates reporting of information such as (RI), and wherein antenna port 15-22 is CSI-RS port.

In LTE-A, especially in collaborative multicast communication (CoMP) scene, the difference of its large scale fading information of the antenna of diverse location has the impact of can not ignore to the feedback of channel information and the transmission of data.In order to measure the large scale fading information of channel more accurately, introduce accurate with location feature for antenna port in the LTE-A R12 stage.If two antenna ports have accurate with location feature, then UE will think that these two antennas have identical large scale fading information.Network side adopts two kinds of standards to receive PDSCH with the one in the type of location by high-level signaling configuration UE, namely accurate with location type A and accurate with location type B.Accurate with in the type A of location, the antenna port 0-3 of hypothesis Serving cell and antenna port 7-22 is accurate with location about Doppler frequency shift (Doppler shift), doppler spread (Doppler spread), average delay (averagedelay), delay spread (delay spread) by UE; Accurate with in the type B of location, UE by hypothesis antenna port 15-22 and antenna port 7-14 about generally strangling frequency displacement (Doppler shift), doppler spread (Doppler spread), average delay (average delay), delay spread (delay spread) be that standard is with location.

Under LTE-A heterogeneous network, because different base station type has stronger interference, more user will send in MBSFN sub-frame simultaneously, can cause off-capacity and the transmission reliability problem of traditional PHICH like this.In order to solve this problem, pertinent literature has proposed the resource of opening up new transmitted uplink ACK/nack message in PDSCH resource, namely strengthens physical mixed repeat requests indicating channel (ePHICH).At present about ePHICH and transmit relevant DMRS to ePHICH and transmit design problem and not yet provide effective solution.
