Description

A kind of Notification Method and device of Physical Uplink Control Channel power control signal

Technical field

The present invention relates to the communications field, in particular to Notification Method and the device of the power control signal of a kind of Physical Uplink Control Channel (Physical Uplink Control Channel, be called for short PUCCH).

Background technology

Long evolving system (Long Term Evolution, abbreviation LTE) defined PDCCH (Physical downlink control channel, Physical Downlink Control Channel) carrying dispatching distribution 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 determined by quantity and the downlink bandwidth of PDCCH.

UE (subscriber equipment) obtains PDCCH by blind Detecting in the search volume, and the search volume is divided into public search space and UE dedicated search space, and public search space refers to the zone that all UE can search, and what carried in this space is the residential quarter 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 be used for cyclic redundancy check (CRC) (the Cyclic Redundancy Check of 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 1.The polymerization rank 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, then in the search volume, detect, until detect the PDCCH that gives oneself.

The uplink physical channel of LTE comprises Physical Random Access Channel (Physical Random Access Channel, abbreviation PRACH), Physical Shared Channel (Physical uplink shared channel, abbreviation PUSCH), Physical Uplink Control Channel (Physical Uplink Control Channel is called for short PUCCH).

In LTE R8/R9/R10 protocol version, the PUCCH channel format can be divided into three major types, totally seven kinds: the first kind comprises three kinds of forms, be format1, format1a, format1b, Equations of The Second Kind equally also comprises three kinds of forms, be format2, format2a, format2b, the 3rd class comprises a kind of form format3.First kind PUCCH is used for transmitting and scheduling request (Scheduling Request is called for short SR) and confirms (Acknowledgement is called for short ACK)/non-affirmation (Negative Acknowledgement is called for short NACK) signaling.Equations of The Second Kind PUCCH is mainly used in transmitting channel state information (Channel State Information is called for short CSI).The 3rd class PUCCH is mainly used in a plurality of ACK/NACK signalings of transmission under the carrier aggregation scene.

In LTE R8/R9/R10 protocol version, the corresponding PUCCH channel of subscriber equipment, for the PUCCH channel, UE different in the residential quarter can pass through code division multiplexing (Code Division Multiplexing, abbreviation CDM) mode is carried out multiplexing, namely adopts different cyclically shifted sequences (CS) or different orthogonal codes (OC).Here different cyclically shifted sequences refers to the same different cyclic shifts that sequence is corresponding.The root sequence is CG-CAZAC (the Computer-Generated Constant Amplitude Zero Auto-Correlation of length=12, the permanent width of cloth that computer generates zero auto-correlation) sequence, quadrature between the different cyclic shifts of same sequence, nonopiate between the different root sequences.According to present PUCCH signaling configuration method, the sequence set of PUCCH numbering is determined by residential quarter ID, so the root sequence of PUCCH is corresponding one by one with residential quarter ID.Therefore, can realize quadrature between the PUCCH in the same residential quarter, when residential quarter ID difference, minizone PUCCH is nonopiate.

In the Rel-10 version LTE agreement, uplink power control is mainly used in path loss (Path Loss is called for short PL) and the shadow fading of compensate for channel, and is used for suppressing presence of intercell interference.When subframe i sent PUCCH to Serving cell c, transmission power control process formula was:

$P_{\mathrm{PUCCH}}\left(i\right)=\min \left\{\begin{array}{c}{P}_{\mathrm{CMAX},c}\left(i\right),\\ P_{0\_\mathrm{PUCCH}}+{\mathrm{PL}}_c+h(n_{\mathrm{CQI}},n_{\mathrm{HARQ}},n_{\mathrm{SR}})+{\mathrm{\Δ}}_{F\_\mathrm{PUCCH}}\left(F\right)+{\mathrm{\Δ}}_{\mathrm{TxD}}\left(F^{,}\right)+g\left(i\right)\end{array}\right\}$

The unit of following formula is dBm, wherein,

P _{CMAX, c}(i): the maximum that is determined by the power grade of UE allows transmitted power.

H (n _CQI, n _HARQ, n _SR) be the value relevant with the PUCCH form, determined by the specifying information bit number that PUCCH carries.

P _{O_PUCCH}: represent on this carrier wave do not consider path loss impact (supposing that UE is just in base station side) time minimum emissive power of UE when satisfying the transmission requirement, P _{O_PUCCH}=P _{O_NOMINAL_PUCCH}+ P _{O_UE_PUCCH}, wherein,

P _{O_NOMINAL_PUCCH}: be for the proprietary parameter in residential quarter that determines the UE minimum emissive power, all UE in the same residential quarter are arranged identical value, by proprietary (cell-specific) RRC (the Radio Resource Control in residential quarter, Radio Resource control) signaling, span: [127 ,-96]; Be the amount (cell specific) relevant with the residential quarter, all UE in the same residential quarter are arranged identical value, scope is [126,24] dBm, and granularity is 1dB, so can represent with 8bit.

P _{O_UE_PUCCH}: be for the proprietary parameter of user that determines the UE minimum emissive power, by proprietary (UE-specific) RRC signaling of user, span: [8,7].

Δ _{F_PUCCH}(F): be the bias relative with PUCCH format 1a, by the proprietary RRC signaling in residential quarter, corresponding different PUCCH form has different values, is configured by high level.

Δ _TxD(F '): by the proprietary RRC signaling of user, whether use the transmit diversity mode to launch the parameter value of decision by PUCCH;

G (i) is UE close-loop power control parameter, according to RRC and TPC (Transmission Power Control, through-put power control) comprehensively obtain, two types of accumulation and current absolute values are arranged, this parameter is the synthesis result of closed-loop power control and minizone power control in the residential quarter.

PL _cBe the downlink path loss value that calculates on this carrier wave, be used for the up path loss and estimate.UE obtains by measuring the downlink path loss.The pilot signal power that UE receives by calculating and base station indicate the difference to the pilot transmit power of UE just can obtain the downlink path loss value by signaling, and the path loss compensation during as the control of upward signal power with the above-mentioned path loss values that calculates.

Path loss is estimated can be expressed as with formula:

PL＝referenceSignalPower-higher layer filtered RSRP，

Wherein, referenceSignalPower is the residential quarter public reference signal power by the high-level signaling configuration;

Higher layer filtered RSRP is the received power (Reference Signal Received Power is called for short RSRP) of the high-rise filtered reference signal of process received of UE termination.

Cooperative multipoint transmission (Coordinated Multi Point Transmission/Reception, being called for short CoMP) technology is to utilize the transmitting antenna cooperation transmission of a plurality of residential quarters to realize higher capacity and the transmitting of cell edge place Radio Link, can effectively solve the cell edge interference problem.The CoMP technology is divided into DL CoMP (down collaboration multi-point) and UL CoMP (uplink coordinated multicast communication) technology, both can improve to a great extent the service quality of average spectral efficiency (ase) and the Cell Edge User of residential quarter.

Under the CoMP scene, the up-downgoing node can independently be selected, wherein, descendant node is selected according to received power, can guarantee the descending quality of reception, upstream node is selected according to path loss, UE can save power overhead like this, therefore there is the inconsistent situation of up-downgoing node, and upstream node may be transparent to UE, to cause the uplink receiving node of the PL value that estimates according to the reference signal that descending sending node sends and reality not larger to the PL value difference between the UE, come the transmitted power of the UE side signal of up link is compensated with downlink estimation PL value out, will cause inaccurate that UE end signal transmitting power estimates, waste UE transmitting power, increase the UE battery loss, affect the reception of upward signal of UE and increase to other users' interference.Simultaneously, under the CoMP scene, upstream node may dynamically switch in a plurality of minizones, so ascending power also needs dynamic adjustment.

In the existing Rel-10 standard, can carry out the power adjustment according to TPC, but because this is a kind of fine setting means, it is shorter that it adjusts step-length, needs the base station repeatedly to issue closed loop power control command instruction UE and adjust just up path loss error compensation to be returned, and expense is larger, and the time is longer, so that UE launched with inappropriate power within longer a period of time, the ascending power of UE can not get reasonable utilization, and increases the interference to other users.

For the problems referred to above, each company has proposed several schemes at present:

Scheme one, path loss biasing (pathloss offset) PL that the user is proprietary _Offset, namely

P _PUCCH(i)＝min{P _CMAX，c(i)，P _{0_PUCCH}+PL _c+PL _offset+h(n _CQI，n _HARQ，n _SR)+Δ _{F_PUCCH}(F)+Δ _TxD(F’)+g(i)}[dBm]；

Scheme two, the road loss compensation factor α that is used for PUCCH that the user is proprietary, namely

P _PUCCH(i)＝min{P _CMAX，c(i)，P _{0_PUCCH}+αPL _c+h(n _CQI，n _HARQ，n _SR)+Δ _{F_PUCCH}(F)+Δ _TxD(F’)+g(i)}[dBm]；

Scheme three, the P of enhancing _{O_PUCCH}, namely enlarge P _{O_PUCCH}Span;

Scheme four, the reference signal power (referenceSignalPower) that the user is proprietary, that is:

Path loss: PL _c=UE-specific referenceSignalPower-higher layer filtered RSRP;

Scheme five, the power bias parameter (Poweroffset) that the user is proprietary, namely

Path loss: PL _c=referenceSignalPower-higher layer filtered RSRP+Poweroffset.

Simultaneously, the inconsistent UE of up-downgoing node will send PUCCH according to the parameter of descendant node, if the cell ID of up-downgoing node (cell ID) difference, nonopiate between the PUCCH that sends and the PUCCH in the upstream node, cause each other interference, affect receptivity.Have with the solution that proposes at present, scheme one, the scheme of a plurality of resource area for example, is configured to the inconsistent UE of up-downgoing node in the newly-increased resource area, and other UE are put in the traditional resource zone.Newly-increased resource area can be by the resource biasing of UE-specific

Realize, even resource index Scheme two, UE-specific root sequence and CS hopping scheme, can realize by UE-specific virtual subdistrict ID is set, for example establish the residential quarter ID that virtual subdistrict ID equals upstream node, make the employing virtual subdistrict ID of the inconsistent UE of up-downgoing node calculate PUCCH and send parameter, so just can realize and other UE that upstream node is interior between quadrature; Scheme three, the combination of the first two scheme, the user device configuration that namely needs is strengthened arrives newly-increased resource area, give simultaneously the user equipment allocation virtual subdistrict ID in newly-increased zone, allow the subscriber equipment in newly-increased zone adopt virtual subdistrict ID to calculate PUCCH transmission parameter, orthogonality between the UE that so both can guarantee to strengthen, can guarantee again the UE that strengthens and the UE that do not have to strengthen between orthogonality.

To the inconsistent UE of up-downgoing node, the enhanced scheme of PUCCH and the enhanced scheme of PUCCH power control can be united consideration, in addition, when adopting above-mentioned PUCCH power control enhanced scheme, what kind of signaling method is required parameter adopt notify to UE, also do not have certain standardization at present.
