Description

The sending method of Physical Uplink Control Channel demodulated reference signal and device

Technical field

The present invention relates to the communications field, in particular to a kind of sending method and device of Physical Uplink Control Channel demodulated reference signal.

Background technology

Third generation partner program (The 3rd Generation Partnership Project, referred to as 3GPP) Long Term Evolution (Long Term Evolution, referred to as LTE) in the system, adopt the mode of base station centralized dispatching to control subscriber equipment (UserEquipment, referred to as UE) the transmission of Physical Uplink Control Channel (Physical Uplink Control Channel is referred to as PUCCH).

Stipulate in the LTE system, when not having upstream data to send, Physical Uplink Control Channel sends at fixing running time-frequency resource.Please refer to Fig. 1, as shown in Figure 1, a Physical Uplink Control Channel accounts for a Resource Block (Resource Block accounts for 12 subcarriers) at frequency domain, continue two time slots in time domain, a subframe (1ms) namely, the difference of the Cyclic Prefix that uses according to current subframe, it symbolic number that comprises is also different.In addition, Physical Uplink Control Channel can carry out frequency hopping at two time slots, to obtain the frequency diversity gain.Usually, in the residential quarter Physical Uplink Control Channel of each subscriber equipment by code divide carry out multiplexing.Because UE number that can be multiplexing on Resource Block is limited, when the number of the UE that needs to send simultaneously Physical Uplink Control Channel in the residential quarter surpasses the multiplexing user's number of Resource Block institute energy, can open up again a Resource Block, namely divide the multiplexing of Physical Uplink Control Channel that the mode that adds frequency division realizes each UE in the residential quarter by code.

In current LTE system, Physical Uplink Control Channel can be supported multiple upstream control signaling, comprise correct/error response message (ACKnowledgement/Non-ACKnowlegement, referred to as ACK/NACK), channel condition information (ChannelState Information, referred to as CSI, comprise CQI (Channel Quality Indicator, referred to as CQI), precoding matrix indicators (Precoding Matrix Indicator, referred to as PMI) and order designator (Rank Indicator, referred to as RI)), dispatch request (Scheduling Request, referred to as SR), and their combinations of sending simultaneously, wherein ACK/NACK and SR adopt control channel form 1 to send, and control channel form 1a/1b is used for sending the ACK/NACK response message of 1 bit/2 bits; Control channel form 2 is used for sending CSI and send simultaneously CSI and ACK/NACK when Cyclic Prefix (Cyclic Prefix is referred to as CP) frame structure; Control channel form 2a/2b is used for sending simultaneously the ACK response message of CSI and 1 bit/2 bits under regular circulation prefix (Normalcyclic prefix is referred to as Normal CP) frame structure.The LTE-A system is the evolution system of future generation of LTE system, has introduced control channel form 3 in the LTE-A R10 stage, and control channel form 3 is mainly used in sending CSI.

In the LTE system, Physical Uplink Control Channel adopts the single antenna port transmission.A system-frame (frame) comprises 10 subframes (subframe), and each subframe comprises 2 time slots (slot).Figure 1A is the reference signal position view according to PUCCH form 1/1a/1b under the regular circulation prefix of correlation technique, shown in Figure 1A, for the Physical Uplink Control Channel form 1/1a/1b under the regular circulation prefix, each time slot is comprised of 4 control signal symbols and 3 demodulated reference signals; Figure 1B is the reference signal position view according to PUCCH form 2/2a/2b/3 under the regular circulation prefix of correlation technique, as shown in Figure 1B, for the Physical Uplink Control Channel form 2/2a/2b/3 under the regular circulation prefix, each time slot is comprised of 5 control characters and 2 demodulated reference signals.Fig. 2 A is extended cyclic prefix (the Extended cyclic prefix according to correlation technique, referred to as Extended CP) the reference signal position view of lower PUCCH form 1/1a/1b, shown in Fig. 2 A, for the Physical Uplink Control Channel form 1/1a/1b under the extended cyclic prefix, each time slot is comprised of 4 control signal symbols and 2 demodulated reference signals; Fig. 2 B is the reference signal position view according to PUCCH form 2/3 under the extended cyclic prefix of correlation technique, shown in Fig. 2 B, for the Physical Uplink Control Channel 2/3 under the extended cyclic prefix, each time slot is comprised of 5 control signal symbols and 1 demodulated reference signal.

In the LTE-A system, Physical Uplink Control Channel can adopt the single antenna port transmission, also can adopt many antenna port transmission.Adopt orthogonal space resource transmission diversity (Spatial Orthogonal-Resource Transmit Diversity is referred to as SORTD) technology to improve the multiaerial system performance of Physical Uplink Control Channel.

The demodulated reference signal of PUCCH (Demodulation Reference Signal, referred to as DMRS) consisted of by sequence on the frequency domain, this sequence is a cyclic shift (Cyclic Shift of reference signal basic sequence, referred to as CS), be quadrature between the different cyclic shifts of same reference signal basic sequence.

Between the demodulated reference signal of the Physical Uplink Control Channel of same residential quarter different user, carry out orthogonalization by different demodulated reference signal cyclic shifts (CS) and/or quadrature mask (Orthogonal Cover Code is referred to as OCC).PUCCH form 1/1a/1b has adopted the OCC code to carry out quadrature, and its length is 3 under the regular circulation prefix, acts on 3 reference signals in the same time slot, and its length is 2 under the extended cyclic prefix, acts on 2 reference symbols of same time slot.

For randomize inter-cell interference, the reference signal sequence of demodulated reference signal configures according to the base station, can realize timeslot-based sequence set saltus step (Group hopping).

At present, among the R10 each residential quarter is determined that the method for its employed basic sequence or sequence set is as follows:

U=(f _Gh(n _s)+f _Ss) mod30, wherein, f _Gh(n _s) expression sequence set saltus step pattern (hopping pattern), f _SsExpression sequence index (sequence index) has been stipulated altogether 17 kinds of sequence set hopping pattern and 30 kinds of sequence index information among the LTE.

The unlatching of sequence set saltus step function or be closed in is controlled by residential quarter proprietary (cell-specific) high-level signaling (Group-hopping-enabled) among the R10.If network side does not send the Group-hopping-enabled signaling to the residential quarter, then for all users: f in this residential quarter _Gh(n _s)=0; If the oriented residential quarter of network side sends signaling, then for all users in this residential quarter:

Wherein, n _sExpression time slot index, c (8n _s+ i) representing pseudo random sequence, its initialization value is:

Wherein,

The expression Cell Identity CI, its attribute is that the residential quarter is proprietary.

Simultaneously, also having defined proprietary (ue-specific) high-level signaling (Disable-sequence-group-hopping) of user among the R10 has used those specific users of OCC technology to close its sequence set saltus step function with realization for the upper DMRS of PUCCH.

For PUCCH, sequence index is:

In order further to realize the presence of intercell interference randomization, adopted the CS hopping technology of the proprietary symbol-based in residential quarter among the R10.All PUCCH forms adopt identical cyclic shift pattern

$n_{\mathrm{cs}}^{\mathrm{cell}}(n_s,l)={\mathrm{\Σ}}_{i=0}^{7}c(8N_{\mathrm{symb}}^{\mathrm{UL}}\·n_s+8l+i)\·2^i,$ Wherein,

Represent the up number of symbols in each time slot, n _sExpression time slot index, l represents notation index in each time slot, and c (i) represents pseudo random sequence, and the initialization value of this pseudo random sequence generator is:

Each radio frames of this initialization value is upgraded once.

Residential quarter with different districts identification number, the root sequence of use is different, is non-orthogonal between the different root sequences, also has different correlations between the different cyclic shifts of different root sequences, therefore, the orthogonality of minizone PUCCH can't guarantee.

In the LTE-A system, in order to improve the transmission rate of cell edge, 3GPP releases coordinated multipoint transmission (CoordinatedMulti-Point Transmission and Reception, referred to as CoMP) technology, it mainly is the message transmission rate that improves edge customer by the cooperation of minizone, although the CoMP technology has been improved the throughput of edge customer, also new challenge has been proposed prior art simultaneously.

The LTE-A R11 stage has proposed four kinds of scenes for the CoMP technology, is respectively: CoMP scene 1, (intra-site) cell cooperative in the isomorphism website; CoMP scene 2, (inter-site) cell cooperative between the isomorphism website; CoMP scene 3, heterogeneous network and macrocell use different cell IDs with all interior Microcells of its coverage; CoMP scene 4, heterogeneous network and macrocell use identical cell ID with the interior Microcell of its coverage.

The introducing of CoMP technology has proposed new challenge to minizone PUCCH quadrature, and new reception technique (for example, uniting reception) in new CoMP scene or the CoMP system is so that may there be following problem in existing PUCCH technology in the CoMP system:

Please refer to Fig. 3, Fig. 3 is according to PUCCH disturbed condition schematic diagram in the heterogeneous network scene of correlation technique, in the heterogeneous network scene of CoMP or when the PUCCH in the CoMP system need to adopt the associating reception technique, can have following PUCCH interference problem:

1, the macrocell user produces than strong jamming, especially in CoMP scene 3 near the Microcell that is positioned at this user;

2, owing to having the asymmetric situation of up-downgoing node in the heterogeneous network, the user who is in user and its up access node in Microcell extended area (Cell Range Extension is referred to as the CRE) scope causes the phase mutual interference;

3, unite and receive down, understand the phase mutual interference between the user of CoMP user and its place cooperative node;

4, use the user of OCC quadrature for the minizone, because their CS saltus step pattern may be inconsistent, cause OCC to be correctly decoded.

The problem that the existing problems of above presence of intercell interference and OCC can't be correctly decoded has had a strong impact on the performance of performance and the CoMP technical advantage of CoMP system.

Problem for the existing problems of disturbing between the correlation technique small area and OCC can't be correctly decoded not yet proposes effective solution at present.
