Description

The collocation method and device of a kind of physical hybrid automatic repeat request indicator channel

Technical field

The present invention relates to moving communicating field, more particularly to the middle-and-high-ranking Long Term Evolutions of 3GPP (Long Term Evolution Advanced, LTE-A) a kind of physical hybrid automatic repeat request indicator channel (Physical in system Hybrid Automatic Repeat Request Indicator Channel, PHICH) collocation method and device.

Background technology

Long Term Evolution (Long Term Evolution, LTE) system, senior long term evolution (LTE-Advanced, LTE- A) system and IMT-Advanced (International Mobile Telecommunication Advanced, IMT- Advanced) system be all with OFDM (Orthogonal Frequency Division Multiplexing, OFDM) based on technology, ofdm system is the data mode of time-frequency bidimensional.1 subframe (subframe) is by 2 time slots (slot) Composition, during normal cyclic prefix (Normal Cyclic Prefix, Normal CP), each slot is by 7 OFDM symbol groups Into；During extension CP (Extended CP), each slot is made up of 6 OFDM symbols.

Describe for convenience, the term in several LTE/LTE-A systems and definition are illustrated below：

1. Resource Unit (Resource Element, RE)：Minimum time/frequency source block, occupies 1 in 1 OFDM symbol Individual subcarrier.

2. resource unit group (Resource Element Group, REG)：According to reference symbol position in each OFDM symbol The difference put, 1 REG can be constituted by 4 or 6 RE.

3. control information unit (Control Channel Element, CCE)：By 36 RE, 9 REG compositions.

4. Physical Resource Block (Physical Resource Block, PRB)：It is continuous 1 time slot, frequency in time-domain It is continuous 12 subcarriers on domain.

5. Physical Resource Block is to (PRB pair)：It is continuous 1 subframe in time-domain, is that continuous 12 sons are carried in frequency domain Ripple.

In LTE/LTE-A systems, base station will be Physical Uplink Shared Channel (the Physical Uplink of each UE Shared Channel, PUSCH) send 1 bit asynchronous mixed automatic retransmission request (Hybrid Automatic Repeat Request, HARQ) descending confirmation/non-acknowledgement (Acknowledge/Negative Acknowledge, ACK/NACK) feedback letter Breath, the HARQ ACK/NACK are carried on Physical HARQ Indicator Channel PHICH.

Its general principle is：Base station end, base station (also referred to as evolved node B, Enhanced Node B, eNB) is by 8 After individual HARQ ACK/NACK carry out 3 repetitions, BPSK modulation, spread spectrum and multiple antennas treatment respectively, 1 PHICH group is multiplexed into On (PHICH group), finally it is mapped on 3 REG.Wherein, so-called spread spectrum, is exactly multiplied by one group of orthogonal sequence, for The situation of Normal CP, spreading factor is 4 (totally 8 groups of orthogonal sequences)；As Extended CP, spreading factor is 2 (totally 2 groups of orthogonal sequences), and using I/Q multiplexings, therefore 1 PHICH group can be multiplexed 8 HARQ ACK/NACK feedbacks of UE At most 8 PHICH are carried in the PHICH group of information, i.e., 1.

Which PHICH group UE ends, UE first has to determine its PHICH resource in, then determines it is in the PHICH groups again Which PHICH.That is, call number (PHICH group index) of the PHICH resource of each UE by PHICH groups And the PHICH call numbers in PHICH groups are uniquely determined, wherein PHICH call numbers are by one group of orthogonal sequence call number (orthogonal sequence index) is uniquely determined.Specifically determined by below equation：

Wherein：

It is the total number of PHICH groups, concrete numerical value is provided by high level；It is the call number of PHICH groups； I_{PRB_RA}The lowest order of the PRB call numbers shared by the PUSCH of UE；It is the call number of PHICH in certain PHICH group, One group of orthogonal sequence of correspondence；n_DMRSValue be given by 3 fixed bit informations in uplink authorization information；It is spread spectrum The factor；I_PHICHIt is that PUSCH occurs I when in subframe 4 or 9 except TDD is with setting to 0 down_PHICHIt is 1, remaining situation is O.

In the GSM for introducing relay nodes (Relay Node, RN), the link of base station (eNB) and RN between Referred to as repeated link (Backhaul Link, also referred to as Un Link), the link between UE under RN and its coverage is referred to as Access link (Access Link, also referred to as Uu Link), the link between UE under eNB and its coverage is referred to as to direct transfer Link (Direct Link).For eNB, RN is equivalent to a UE；For UE, RN is equivalent to eNB.

Via node can be divided into two types, i.e., with interior via node and with outer via node.

For via node in band (in-band RN), Un Link and Uu Link use identical frequency band, such as Fig. 1 institutes Show, Un Link and Uu Link use f₁.In order to avoid the transmitting-receiving of RN itself is disturbed, RN can not be same in same frequency resource When the operation that is transmitted and receives.When RN sends Downlink Control Information to its subordinate UE, just can not receive from the descending of eNB Control information.Therefore, in downlink transfer, RN sends descending control first in preceding 1 or 2 OFDM symbol to the UE of its subordinate Information, then (being spaced gap as shown in Figure 2) in the range of a period of time from the switching for being transmitted into reception, switched Cheng Hou, receives the data from eNB in the OFDM symbol below, including the down control channel (Relay of relaying itself Physical Downlink Control Channel, R-PDCCH) and Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH), as shown in Fig. 2 i.e. eNB is to be carried on physics money to the R-PDCCH that RN sends Source block or Physical Resource Block are to upper.

For the outer via node (out-band RN) of band, Un Link and Uu Link take two entirely different frequencies Section, as shown in figure 3, Un Link use f₁, Uu Link use f₂.Therefore, can be in f with outer RN₁While upper transmission (reception) In f₂Upper reception (transmission), will not produce interference each other.

In the in-band RN of the fixation of Rel-10, it is contemplated that backhaul link channel conditions are relatively good, transmit out Error rate is extremely low, and also to avoid introducing complexity and the unnecessary wasting of resources that PHICH is brought, therefore does not have finally For fixed in-band RN introduce PHICH.

In 3GPP discussion, mobile relay (Mobile Relay, MR) turns into hot issue gradually.If mobile relay is Outside band, then with the information that outer mobile relay can just be sent with As-received station in any OFDM symbol of every subframe.Therefore It is readily conceivable that can reuse PHICH carrys out downlink feedback information of the carrying belt outward corresponding to the uplink of mobile relay.

However, when mobile relay is in High-speed Circumstance, quick channel variation will certainly cause the mistake that business is transmitted Rate is unprecedented soaring by mistake, retransmits probability and becomes big, therefore very necessary for mobile relay introducing PHICH is used for supporting that non-self-adapting is retransmitted, The expense of control signaling is reduced simultaneously.Now first have to solve the problems, such as to be how to ensure PHICH transmission reliabilities in itself.
