The techniques described herein can be implemented in multi-carrier wireless communications system.One exemplary wireless communication system can use OFDM (OFDM), and whole system bandwidth partition is become multiple (N by itF) individual subcarrier, subcarrier may also be referred to as frequency subchannels, tone or frequency.Data waiting for transmission (that is, information bit) encode first with specific encoding scheme, and to produce encoded bit, encoded bit is combined into many bit symbols further, and these symbols are mapped to modulation symbol subsequently.Each modulation symbol is corresponding to a point in signal constellation (in digital modulation) figure defined in the certain modulation schemes (such as, M-PSK or M-QAM) for data transmission.In the time interval of each bandwidth depending on each frequency sub-carrier, modulation symbol can be at NFThe each upper transmission of individual subcarrier.Then, OFDM may be used for the intersymbol interference (ISI) prevented caused by frequency selective fading, and wherein, frequency selective fading is characterised by that attenuation is different in the range of cross-system bandwidth.

Generally, wireless multiple-access communication system can support the communication of multiple wireless terminal simultaneously.Each terminal is all communicated with one or more base stations by the transmission on forward link and reverse link.Forward link (or downlink, DL) refers to the communication link from base station to wireless terminal.Reverse link (or up-link, UL) refers to the communication link from terminal to base station.In multi-carrier systems, one or more component carriers (CC) can be only fitted on DL and UL of each wireless terminal.This configuration can be symmetrical (wherein, wireless terminal has downlink component carrier and the uplink component carrier of equal number), or asymmetrical (wherein, wireless terminal has downlink component carrier and the uplink component carrier of varying number).The transmission mode of each CC is configured the most discretely.

MIMO transmission uses multiple (NTIndividual) launch antenna and multiple (NR) reception antenna.By NTIndividual transmitting antenna and NRThe mimo channel that individual reception antenna is formed can resolve into NSThe independent channel of individual also referred to as space channel, wherein, NS≤min{NT,NR}。NSEach independent channel in individual independent channel both corresponds to one-dimensional.If using the extra dimension created by multiple transmitting antennas and reception antenna, then MIMO transmission can provide the performance (such as, higher handling capacity and/or preferably reliability) of improvement.Mimo system also supports time division duplex (TDD) and FDD (FDD) system.In a tdd system, forward link transmissions and rl transmission are in same frequency field, in order to reciprocal principle allows according to reverse link channel estimation forward link channel.This makes when multiple antennas can use in base station, and the launching beam shaping gain on forward link can be extracted in base station.

Often group antenna and/or the region of specifying them to be used for communicating are commonly referred to the sector of base station 102.For example, it is possible to the antenna sets shown in design drawing 1 communicates from the subscriber equipment 116,122 in the different sectors of base station 102.On forward link 120 and 126, the transmitting antenna of base station 102 uses beam shaping, to improve the signal to noise ratio of the forward link for different user devices 116 and 122.Beam shaping is used to be transmitted can reducing the interference volume of subscriber equipment in neighbor cell to the subscriber equipment being randomly dispersed within overlay area.

Fig. 2 is the other aspect illustrating exemplary multi-carrier wireless communications system 200, and it can combine description with Fig. 1.As indicated, system 200 includes base station 210 (also referred to as " transmitter system ", " access point " or " e node B ") and subscriber equipment 250 (also referred to as " receiver system " or " access terminal ").Even if it should be appreciated that base station 210 is referred to as transmitter system and subscriber equipment 250 is referred to as receiver system, as indicated, so these systems are also two-way communications.Then, term " transmitter system " is not limited to " receiver system " communicate from the one direction of any system.Further, it should also be noted that the transmitter system 210 of Fig. 2 all can communicate with other Receiver And Transmitter systems multiple with receiver system 250.

At base station 210, provide the business datum of multiple data stream to transmitting (TX) data processor 214 from data source 212.Each data stream can be sent by corresponding transmitter system.TX data processor 214 is based upon the specific coding schema format of data stream selection, encodes and the business datum of each data stream that interweaves, to provide encoded data.The encoded data of each data stream such as uses OFDM technology and pilot data multiplexing.Pilot data is typically the well known data scheme processed in known manner, and is used for estimating channel response at receiver system.Subsequently, the multiplexed pilot of each data stream and encoded data be based upon data stream select certain modulation schemes (such as, BPSK, QPSK, M-PSK or M-QAM) be modulated (symbol mapping), to provide modulation symbol.The data rate of each data stream, encode and modulate the instruction that can be performed by the processor 230 of transmitter system 210 and determine.

In this example, the modulation symbol of all data streams can be supplied to TX MIMO processor 220, and it can perform further to process (such as, for OFDM).Then, TX MIMO processor 220 is to NTIndividual transmitter system transceiver (TMTR) 222a-222t provides NTIndividual stream of modulation symbols.TX MIMO processor 220 applies beam-forming weights to the symbol of data stream and the antenna 224 of transmission symbol.

Transceiver 222a-222t at base station 210 receives and processes corresponding symbol stream, and to provide one or more analogue signal, a step joint analogue signal of going forward side by side, to provide the modulated signal being applicable to transmission.In some systems, regulation can include but not limited to such as to amplify, filter, the operation of up-conversion etc.Then, the modulated signal of transceiver 222a-222t is transmitted from the antenna 224a-224t of the transmitter system 210 shown in Fig. 2 respectively.

At subscriber equipment 250, the modulated signal sent is received by antenna 252a-252r, and the signal received from each receiver system antenna 252a-252r is supplied to corresponding transceiver (RCVR) 254a-254r.The signal that each transceiver 254a-254r regulation receives signal accordingly, digitized is adjusted at subscriber equipment 250 is to provide sample, and processes sample further, to provide corresponding " receiving " symbol stream.Regulation can including, but not limited to such as filtering, amplifying, the operation of down coversion etc.

RX data processor 260 receives and processes the symbol stream received from transceiver 254a-254r based on specific receiver treatment technology, to provide multiple " after testing " symbol stream.In one example, each symbol stream after testing can include the symbol of the estimation as the symbol sent for corresponding data stream.RX data processor 260 demodulates, deinterleaves and decodes each symbol stream after testing, to recover the business datum of respective stream of data.The process that TX MIMO processor 220 and TX data processor 214 at the process of RX data processor 260 and transmitter system 210 performs is complementary.RX data processor 260 can provide treated symbol stream to slot data 264 extraly.

Channel response is estimated to be produced by RX data processor 260, and for the execution space/time-triggered protocol at receiver system, regulation power level, change modulation rate or scheme, and/or other suitable action.Additionally, RX data processor 260 can estimate the characteristic of channel further, the signal to noise ratio (SNR) of symbol stream the most after testing and signal-to-noise ratio (SIR).Then, RX data processor 260 can provide the estimated characteristic of channel to processor 270.In one example, the RX data processor 260 of receiver system and/or processor 270 can obtain channel condition information (CSI), and it can include about communication link and/or the information of received data stream.

CSI can such as include the different types of information about channel conditions.Such as, CSI includes the order designator (RI) of each CC for being allocated to base station 210, CQI (CQI) and/or pre-coding matrix (PMI).Processor 270 can produce CSI report, and it includes PMI, CQI and/or RI for being allocated to one or more carrier waves that subscriber equipment 250 uses.CSI report can select from one group of predetermined Report Type, and each Report Type may each comprise different types of CSI and/or payload size.

Termly, or when transmitter system 210 triggers, subscriber equipment 250 can send CSI report and the CSI for one or more component carriers.Periodically CSI report can be semi-statically configured for each component carrier by base station 210 by wireless heterogeneous networks (RRC) signaling.Described configuration can particularly point out the type of opportunity and the CSI report for certain components carrier wave making CSI report.Such as, configuration may indicate that the cycle of each configured CC.As a result, the CSI report for different CC and/or the different types of CSI for single CC can become and transmit (that is, transmitting potentially conflicting) in same subframe.

Such as, if the report period assignment with 3 subframes is used for the CSI report of component carrier #1, and being used for the CSI report of component carrier #2 with the report period assignment of 4 transmission subframes, then two individual subframes of CSI report every 12 (that is, the least common multiples of 3 and 4) just will conflict.In some cases, can be used for reporting that the payload size of CSI may be not enough to accommodate all CSI that transmit in specific sub-frame, and subscriber equipment 250 can carry out prioritization across this group component carrier wave and in this group component carrier wave to CSI.

The CSI report received by transmitter system 210 may be used for making suitable decision, such as, arrange about scheduling, MIMO, modulate and codes selection, it is possible to use different control format to be sent by subscriber equipment 250.Such as, CSI report can use the DFT-S-OFDM form of the PUCCH format 3 proposed by PUCCH format 2/2A/2B or such as LTE form 10 that such as LTE version 8 defines, and is sent to base station 210 in Uplink Control Channel (PUCCH) physically in one or more uplink component carrier.

Receiver system 250 is able to receive that and processes the signal of spatial reuse.Spatial reuse can be performed at transmitter system 210 by multiplexing on transmitter system antenna 224a-224t and transmission different data streams.This is contrary with the use of emission diversity scheme, and in emission diversity scheme, identical data stream sends from multiple transmitter system antenna 224a-224t.In the MIMO communication system receiving and processing spatial reuse signal, pre-coding matrix is generally used at transmitter system 210, to guarantee that the signal from each transmitter system antenna 224a-224t transmission all can be the most mutually de-correlated.This decorrelation guarantees that the composite signal arriving any specific receiver system antenna 252a-252r can be received, and can determine each data stream in not carrying in the case of the signal of other data stream of other transmitter system antenna 224a-224t.

Owing to the crosscorrelation amount between stream is affected by environment, so for receiver system 250, it is advantageous that feed back to the information about received signal to transmitter system 210.Such as, transmitter system 210 and receiver system 250 can include the code book with multiple pre-coding matrix.In some instances, each in these pre-coding matrixes can be relevant to the crosscorrelation amount that the signal received is experienced.It is favourable owing to sending the value in specific matrix index rather than sending metrix, so receiver system 250 can send the CSI report with PMI information to transmitter system 210.Can also send and indicate the order designator (RI) using the most independent data stream in spatial reuse to transmitter system 210.

System 200 can also use emission diversity scheme rather than above-mentioned spatial multiplex scheme.In these examples, identical data stream is sent across transmitter system antenna 224a-224t.The data rate being sent to receiver system 250 is usually less than spatial multiplexing MIMO communication system 200.Emission diversity scheme can provide robustness and the reliability of communication channel.The each signal sent from transmitter system antenna 224a-224t is by the different interference environment of experience (such as, decline, reflect, multipath phase shift).The unlike signal characteristic received at receiver system antenna 252a-254r is useful when determining suitable data stream.

Other example can use spatial reuse and launch the combination of diversity.Such as, in the system with 4 antennas 224, the first data stream can send on two antennas, and the second data stream can send on remaining two antennas.In the system that these are exemplary, the order designator for channel could be arranged to the integer lower than the full order of pre-coding matrix, to use spatial reuse to transmitter system 210 instruction and to launch the combination of diversity.

In transmitter system 210, the modulated signal from receiver system 250 is received by antenna 224, transceiver 222 regulate, is demodulated by demodulator 240, and is processed by RX data processor 242, the reverse link message sent by receiver system 250 with extraction.Subsequently, the processor 230 at transmitter system 210 determines which pre-coding matrix is for forward link transmissions in the future.Processor 230 also uses received signal to adjust beam-forming weights for following forward link transmissions.

According to the disclosure, multicarrier UE may determine that the priority for sending the CSI being associated with one or more component carriers in specific sub-frame.This priority can be based on the order of configured CC.Such as, priority can be based at least partially on corresponding RRC configuration index, such as, for the value of the intersection carrier indication field (CIF) of certain components carrier wave.CSI can also carry out prioritization based on CSI type to be reported.Such as, UE can be configured to send different types of CSI report for different configured CC.Different Report Types includes the CSI information with the different priorities across CC successively.

In the case of UE is configured with two component carriers, it is possible to specify one-component carrier wave can specify another component carrier as auxiliary component carrier (SCC) as principal component carrier wave (PCC).The CSI report for PCC can be given than the higher priority of CSI report for SCC, so that when the CSI report being allocated to PCC and SCC is conflicted in uplink sub-frames, UE can be in that specific sub-frame, and priorization is for the CSI report of PCC, and abandons the CSI report for SCC.

In the case of more than two downlink component carrier is configured with for UE, it is possible to specify one-component carrier wave is as principal component carrier wave (PCC), and specifies other component carrier as auxiliary component carrier (SCC).SCC can be ranked up according to corresponding RRC configuration index (the such as value of they multi-carrier indicator fields (CIF)) further, and/or is ranked up according to transmission mode.When being ranked up with transmission mode, the MIMO carrier wave ratio higher priority of SIMO carrier wave can be given.In one example, according to carrier frequency, SCC is ranked up.When the conflict occurs, CSI is reported according to priority, it is possible to abandon in specific subframe for lower priority CC or the CSI of CSI type.

In some instances, multicarrier UE is configured to use the PUCCH format compatible with DFT-S-OFDM waveform.Such as, UE can be configured to use DFT-S-OFDM waveform and the PUCCH format of such as LTE version 10.In this case, PUCCH payload can accommodate more than one CSI report in subframe.If during only one of which CSI report should be transmitted in specific sub-frame, then UE can return back to PUCCH format 2/2A/2B;Otherwise, it will fill available payload according to priority by multiplexing CSI and/or CSI report.When producing the payload of multiplexing, CSI can also be sorted by UE with type and/or component carrier.

Additionally, multicarrier UE can carry out prioritization in conjunction with the state of activation of its CC configured to CSI report.In any given time, the CC configured can be to activate or deexcitation determined by such as serving BS.Configuring according to it, UE can suspend CSI report, simultaneously deexcitation CC, regardless of its priority.Alternatively, it is possible to send predetermined pattern or bit sequence replaces the CSI for deexcitation CC.

When UE is configured with multiple (two or more) component carrier and PUCCH format, wherein PUCCH format has the payload capacity size once accommodating more than one CSI report, can with in the same subframe of multiplexing the CSI element of different CC of configuration CC and/or CSI report, until available payload size.If all CSI report should transmitted in specific sub-frame all can be multiplexed into PUCCH payload, then UE can use prioritization to come the CSI element in PUCCH payload and/or CSI report and sort.If all CSI report should transmitted in particular time-slot multiplexing (coupling) can not arrive PUCCH payload, so UE can select the CSI report of a subgroup according to the first priority, and is ranked up the CSI report selected in PUCCH payload according to the second priority.

CSI report select and sequence in PUCCH payload can the sub-bands of frequencies that is associated with CC of carrier index based on CSI report type, component carrier or its combination in any.On the one hand, the a type of CSI that prioritization can include only selecting and sort in given subframe is (such as, RI, CQI or PMI), or prioritization can include the combination (such as, RI&CQI, RI&PMI, CQI&PMI) of dissimilar CSI element.As an example, in one group of CC, RI report can have precedence over any one report in CQI, PMI report and subband CQI.And, the CSI for auxiliary component carrier can be had precedence over for the CSI of PCC.

UE can be configured with MIMO (multiple-input and multiple-output) component carrier and/or SIMO (single input and multi-output) component carrier.CSI report for MIMO component carrier can have precedence over the CSI being associated with SIMO component carrier.The CSI report being associated with MIMO component carrier can according to CSI report type (such as, RI, CQI, PMI and subband PMI) order carry out prioritization, and/or be ranked up according to carrier index, the sub-bands of frequencies of MIMO component carrier or a combination thereof of MIMO component carrier.

When multiplexing CSI report, in the case of the size of the CSI report that should transmit exceedes maximum PUCCH payload size, UE can be configured to maximize the CSI report number for PUCCH payload.Such as, prioritization can include the CSI report part first selecting have minimum bit wide, then selects have time CSI report part of minimum bit wide etc., until reaching maximum PUCCH payload size.

UE can receive RRC signaling, and one or more configured CC are appointed as activation by it, and one or more configured CC are appointed as deexcitation.UE can be configured to based on priority multiplexing only for the CSI of component carrier activated, until reaching payload capacity size or all CSI for the component carrier activated have been re-used.Alternatively, UE can be configured to multiplexing for CSI report and the zero padding of the component carrier of one or more activation or the CSI report of the component carrier for one or more deexcitations filling certain other preassigned pattern, until reaching payload capacity size or all CSI for the component carrier activated in subframe and the component carrier of deexcitation have been re-used.

In the case of the payload size of multiplexing CSI needs is less than payload capacity size, UE can include CSI report and the carrier index of the component carrier with optimal channel quality at each CSI report example.On the one hand, in the case of the component carrier with optimal channel quality is MIMO component carrier, UE can according to determined by priority report the RI of component carrier, the CQI of component carrier and component carrier PMI in one or more.
