Description

A kind of Notification Method and system of uplink demodulation pilot tone control signaling

Technical field

The present invention relates to the communications field, relate in particular to a kind of Notification Method and system of ascending pilot frequency control signaling.

Background technology

Long Term Evolution (Long Term Evolution is called for short LTE) system accurately studies the R11 technology again successively after having experienced the several versions of R8/9/10.At present part R8 product begins progressively commercially, and R9 and R10 remain further product programming.

Experiencing R8 and R9 stage, R10 has increased a lot of new characteristics again on the above two basis, demodulation pilot frequency DRS (Demodulation Reference Signal for example, demodulated reference signal), CSI-RS (Channel State Information Reference Signal, channel state information reference signals) pilot tone characteristic such as, transmission such as 8 antenna supports and feedback characteristics or the like, eICIC (ehanced Inter-Cell Interference Cancellin particularly, presence of intercell interference counteracting enhancing) technology is further considered the interference avoidance technique between the sub-district on the basis of having considered R8/9ICIC (presence of intercell interference counteracting).Consider mainly that at the R10 initial stage in stage the area interference under the homogenous networks avoids for the technology that solves interference problem between the sub-district, wherein the consideration eICIC technology of main flow and CoMP (Coordinated Multi-point, multipoint cooperative) technology.CoMP is as the term suggests be exactly that a plurality of node cooperations send data at identical running time-frequency resource or different running time-frequency resources for one or more UE (subscriber equipment).Technology can reduce the interference between the sub-district like this, improves the throughput of cell edge, enlarges the sub-district and covers.But introduced more scene owing to considered heterogeneous network in the discussion later stage, the time restriction that the complexity of CoMP technology and R10 discuss, final decision is not introduced extra CoMP standardized content in the R10 stage, but the demand that can consider the CoMP part at design CSI-RS designs, so the CoMP technology is not just carried out further discussion after the 60bis meeting.

LTE has defined PDCCH (Physical downlink control channel, Physical Downlink Control Channel) the carrying scheduling distributes and other control information, each PDCCH is by several CCE (Control Channel Element, the control channel unit) form, the CCE number of each subframe is by the quantity of PDCCH and descending) the bandwidth decision.

UE obtains PDCCH by blind Detecting in the search volume, and the search volume is divided into common search space and UE dedicated search space, and the common search space is meant the zone that all UE can search, and what carried in this space is the sub-district Proprietary Information.The dedicated search space is the spatial dimension that single UE can search, and the dedicated search space of a plurality of UE might be overlapping, is that general initial searching position is different.Before the blind check, by high-level signaling notice UE mode of operation and cyclic redundancy check (CRC) (the Cyclic Redundancy Check that is used for PDCCH, abbreviation CRC) Radio Network Temporary Identifier of scrambling (Radio Network Temporary Identity is called for short RNTI) type.

The search volume

With polymerization rank L and candidate PDCCH quantity M ^(L)Between relation see Table 2, table 2 is a PDCCH Candidate Set table.The polymerization grade is the CCE number that PDCCH takies.When blind Detecting was carried out in user's dedicated search space, subscriber equipment at first calculated blind check initial position Y according to user ID (UE ID) and subframe numbers etc. _k, in public or dedicated search space, detect then, till detecting the PDCCH that gives oneself.

Table 2

The corresponding relation of the relative position of first control channel unit of polymerization rank and PDCCH in user's dedicated search space sees Table 3, and table 3 is the mapping table of polymerization rank and first CCE position.The relative position of first control channel unit of PDCCH in user's dedicated search space refers to first CCE index nCCE and the blind check initial position Y that PDCCH takies _kRelative position, use nCCE herein, offset represents, nCCE, offset=nCCE-Y _k, nCCE, the span of offset is 0～6,8,10.As shown in Figure 3, be UE dedicated search space, the schematic diagram of the polymerization grade of first possible CCE position and correspondence thereof.

In LTE R10 (version 10), can effectively support Single User MIMO (multiple-input, multiple-output) (Single User-MIMO based on demodulation pilot frequency, abbreviate SU-MIMO as) and single sub-district in multiuser MIMO (Multiple User-MIMO, abbreviate MU-MIMO as), but, be still waiting further enhancing for minizone MU-MIMO.In the LTE-A system, especially in the up CoMP system, a plurality of sub-districts need simultaneously to targeted customer (User Equipment, abbreviate UE as) service, if at this moment the targeted customer is SU, though the targeted customer can obtained performance gain by CoMP, may cause the decline of certain wasting of resources or system's average throughput but then, therefore, in order more effectively to utilize system resource, up CoMP system has higher requirement to minizone MU (Multiple User, multi-user or pairing user), comprises the orthogonality that can support simultaneously between more number of users and these multi-users etc.

For minizone MU, if the different uplink demodulation pilot frequency sequence group of different districts configuration can only pass through quadrature mask (Orthogonal Cover Code abbreviates OCC as) quadrature, and at most can only multiplexing 2 users of while; If the uplink demodulation pilot frequency sequence group that the different districts configuration is identical then can be by using cyclic shift (Cyclic Shift abbreviates CS as) and/or the multiplexing more user of OCC mode.So need to consider how to make that the UE in a plurality of sub-districts adopts identical demodulation pilot frequency root sequence to send, the discussion of meeting is formerly considered mainly that the bias that adopts high-level signaling or physical layer signaling to notify demodulation pilot frequency may also comprise and is reused among the existing PDCCH or the bit among the UL-Grant (uplink authorization) indicates its root sequence to dispose bias.But still the problem that may exist is if adopt the OCC quadrature, capable physically at present shared channel (Physical Uplink Shared Channel, abbreviate PUSCH as) in the CS saltus step mode of demodulation pilot frequency sequence can't guarantee that the CS saltus step pattern between the MU user of minizone is the same, cause to exist between the MU user CS collision problem or OCC to be correctly decoded, thereby influence minizone MU user's performance.So for the quadrature that guarantees UE between different districts may need UE to carry out the mode of sub-frame level or this slot hopping of disable (closing) (sequence jump between time slot) or indicates the UE of pairing to adopt any slot hopping bias by dynamic signaling.

At present, among the R10 each sub-district is determined that the method for its employed sequence set is as follows:

u＝(f _gh(n _s)+f _ss)mod 30，

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

The unlatching of sequence set saltus step function or be closed in is controlled by sub-district specific (cell-specific) high-level signaling Group-hopping-enabled (unlatching group sequence jump) among the R10.If network side does not send the Group-hopping-enabled signaling to the sub-district, then for all users in this sub-district:

f _gh(n _s)＝0；

If the oriented sub-district of network side sends signaling, then for all users in this sub-district:

$f_{\mathrm{gh}}\left(n_s\right)=({\mathrm{\Σ}}_{i=0}^{7}c({8n}_s+i)\·2^i)\mathrm{mod}30;$

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

Wherein,

The expression cell ID.

(ue-specific) high-level signaling Disable-sequence-group-hopping (shutdown sequence group hopping function) that has also defined user's special use simultaneously among the R10 is to realize that going up demodulation pilot frequency at PUSCH has used those specific users of OCC technology to close its sequence set saltus step function.

For PUCCH: $f_{\mathrm{ss}}^{\mathrm{PUCCH}}=N_{\mathrm{ID}}^{\mathrm{cell}}\mathrm{mod}30,$

For PUSCH, $f_{\mathrm{ss}}^{\mathrm{PUSCH}}=(f_{\mathrm{ss}}^{\mathrm{PUCCH}}+{\mathrm{\Δ}}_{\mathrm{ss}})\mathrm{mod}30,{\mathrm{\Δ}}_{\mathrm{ss}}\∈\{\mathrm{0,1},...,29\}.$

Wherein, Δ _SsIt is a higher level parameters that the sub-district is specific.Under the situation that sequence set saltus step function is closed, network side can realize that the PUSCH of different districts uses identical demodulation pilot frequency sequence group by the coordination configuration of this parameter.And under the situation that sequence set saltus step function is opened, can't support the PUSCH of any two or more different districts all to use identical demodulation pilot frequency sequence group in the present standard, at this moment just can't realize the multiplexing of inter-cell user by CS.

At present, among the R10 each sub-district is determined that the method for sequence in its employed group is as follows:

Wherein, pseudo random sequence c (n _s) promptly represent the hopping pattern of sequence, its initial value satisfies:

The unlatching of sequence jump function or be closed among the R10 by the specific high-level signaling Sequence-hopping-enabled in sub-district (opening the sequence jump function) is controlled in the group, and specific (ue-specific) high-level signaling Disable-sequence-group-hopping (shutdown sequence group hopping function) of above-mentioned user that defines among the R10 also can be used for the specific user is closed sequence jump function in its group simultaneously.Interior sequence set saltus step function of group specified and sequence jump function can not be used simultaneously among the R10.

In group, under the sequence jump function unlatching situation, can't support the PUSCH of any two or more different districts all to use identical demodulation pilot frequency sequence in the present standard, at this moment also can't realize the multiplexing of inter-cell user by CS.

At present, among the R10 each user is determined that the method for its CS is as follows:

$n_{\mathrm{cs},\mathrm{\λ}}=(n_{\mathrm{DMRS}}^{\left(1\right)}+n_{\mathrm{DMRS},\mathrm{\λ}}^{\left(2\right)}+n_{\mathrm{PN}}\left(n_s\right))\mathrm{mod}12,$

Wherein,

Dispose by high-level signaling by network side,

Dispose by PDCCH by network side,

With Determined user's CS saltus step initialization value jointly.

$n_{\mathrm{PN}}\left(n_s\right)={\mathrm{\Σ}}_{i=0}^{7}c({8N}_{\mathrm{symb}}^{\mathrm{UL}}\·n_s+i)\·2^i$ Expression CS saltus step pattern, its pseudo random sequence initial value is:

When having minizone MU, network side can pass through higher level parameters

Coordinate the initialization CS value of minizone, but because the cell ID of different districts

And/or sequence index information

Inconsistent, so, can't guarantee that the CS saltus step pattern between the MU user of minizone is identical.

In up CoMP system, usually have a plurality of edge UE in the sub-district, because definition cooperation set is that the user is specific in R11, i.e. the cooperation cell of each edge UE set all may be different, and network side is difficult to by the specific higher level parameters Δ in sub-district among the present R10 _SsEach cooperation cell that guarantees each edge UE is used identical sequence set respectively.On the other hand, if allow too much sub-district use same sequence set, also can cause the interference problem of demodulation pilot frequency capacity problem and inner other UE in these a plurality of sub-districts.So, in up CoMP system, take all factors into consideration cooperation aggregating characteristic, capacity and interference problem, network side can be selectively to different districts configuration identical sequence group or different sequence set.Therefore with respect to R10, the inconsistent problem of demodulation pilot frequency sequence saltus step pattern can be more outstanding in up CoMP system.

Some problems according to R10, present many companies mainly consider to dispose PUCCH (Physical Uplink Control CHannel based on the mode of UE-Specific, physical uplink control channel) and the root sequence bias of the demodulation pilot frequency of PUSCH (Physical Uplink Shared Channel), promptly make Δ _PUSCHAdopt the mode of UE-Specific, calculating

With

After can adopt a UE-Specific bias Δ respectively _PUCCH(biasing of PUCCH root sequence) or Δ _PUSCHThe root sequence of (biasing of the PUSCH root sequence) UE that setovers.Also can adopt configuration virtual sub-district ID

Mode make specific UE adopt identical root sequence and identical CS Hopping (Cyclic Shift Hopping, cyclic shift saltus step) pattern Pattern.Also can make the UE of pairing adopt identical CS Hopping Pattern by the mode that disposes fixing CS Hopping Pattern.

Part company considers for the utilance that improves ascending resource and avoids interference between the different districts UE in addition, and can be so that the UE of different bandwidth adopts FDM (Frequency-division multiplexing, frequency division multiplex) mode realizes quadrature, the mode of demodulation pilot frequency IFDM (Interleave Frequency Division Multiplex, frequency division multiplexing interweaves) has been proposed.At this moment the different carrier that different UE can take same resource block is realized the quadrature of demodulation pilot frequency, how to be notified to the mode that mode that UE adopts IFDM still adopts traditional R8/9/10 so need further consider the mode of this IFDM, perhaps after the mode that has adopted IFDM, how to notify which carrier wave of UE employing IFDM mode or perhaps the signaling mode of comb (dressing frequency domain carrier wave), do not have certain standardization at present.
