Specific embodiment

It is to condense together 2 or more member carriers (Component Carrier, abbreviation CC) to form carrier wave set to support bigger transmission bandwidth that carrier wave, which polymerize (Carrier Aggregation, abbreviation CA),.In CA scene, the feedback message of multiple carrier waves is only fed back in carrier wave set by a carrier wave, i.e., all carrier waves receive the feedback message (ACK or NACK) after data packet all by a fixed carrier wave transmission in carrier wave set.In CA scene, main plot (Primary CC, abbreviation PCC) and secondary cell (Secondary CC, abbreviation SCC) are configured with for user equipment (User Equipment, abbreviation UE).The carrier units that main plot uses are known as principal component carrier wave (Primary Component Carrier, abbreviation PCC), also referred to as main carrier, the carrier units that secondary cell uses are known as auxiliary component carrier (Secondary Component Carrier, abbreviation SCC), also referred to as secondary carrier.

Carrier aggregation scene can be applied between base station and UE, can also apply between two base stations, such as apply between macro station and base station.Fig. 1 is that a kind of schematic diagram of carrier aggregation scene can also be communicated as shown in Figure 1, can be communicated by two carrier waves CC1 and CC2 between base station and UE between macro station and small station by two carrier waves CC1 and CC2.

Fig. 2 is the flow chart of the data transmission method under a kind of multicarrier that the embodiment of the present invention one provides, the method of the present embodiment can be applied to downlink data transmission, also it can be applied to transmitting uplink data, when this method is applied to downlink data transmission, first equipment can be base station, the second equipment can be base station or UE, such as, when the first equipment is macro station, the second equipment can be small station.When this method is applied to transmitting uplink data, the first equipment is UE or base station, and the second equipment is base station.As shown in Fig. 2, the method for the present embodiment may include:

Step 101, the first equipment, which determine, uses multicarrier HARQ mode.

Multicarrier HARQ mode is a kind of transmission mode that the present invention newly defines, different from existing single carrier HARQ mode, under multicarrier HARQ mode, first equipment determines the carrier wave and subframe for receiving that the feedback message of TB uses from multiple carrier waves, in the present embodiment, the HARQ sequential relationship that first equipment is configured with specific reference to multicarrier frame, determine the carrier wave and subframe for receiving that the feedback message of TB uses, and under single carrier HARQ mode, the HARQ timing that the first equipment can only be configured according to single carrier frame determines the carrier wave and subframe for receiving that the feedback message of TB uses.

It should be clear that, the HARQ sequential relationship of multicarrier frame configuration is not simply to put together the HARQ timing that the frame of multiple single carriers configures, but the HARQ timing of multiple carrier waves is adjusted, by adjusting HARQ timing, so that round-trip delay (the Round-Trip Time of data packet, abbreviation RTT) it reduces, so as to reduce time delay.

Assuming that there are two carrier waves altogether, carrier wave 1 is using frame configuration 1, carrier wave 2 is using frame configuration 0, Fig. 3 is the schematic diagram of the data transmission and reception sequential relationship of frame configuration 1, Fig. 4 is the schematic diagram of the data transmission and reception timing of frame configuration 0, as shown in Figure 3, frame configuration 1 has 7 processes, wherein the first row indicates subframe (subframe) number, second row indicates that corresponding subframe is downlink subframe (D), special subframe (S) or sub-frame of uplink (U), every row after the third line indicates that a different process, the data transmission and reception timing of different processes are different.By taking process 0 as an example, eNB sends data (Tx) in the subframe 0 of a radio frames, and UE sends Ack in the subframe 7 of the radio frames and replys, and eNB exists The subframe 1 of next radio frames sends data (Tx), and the RTT time of the process of frame configuration 1 is 11ms or 13ms.As shown in figure 4, frame configuration 0 has 4 processes, the RTT time of all processes is 10ms.

Fig. 5 is a kind of schematic diagram of the data transmission and reception sequential relationship of multicarrier frame configuration, wherein, carrier wave 1 is using frame configuration 1, and carrier wave 2 is using frame configuration 0, it, can only feeding back ACK message or NACK message on carrier 1 in the data transmission and reception sequential relationship of multicarrier configuration.As shown in figure 5, the RTT time of all processes is all 11ms, it, can be in the subframe of carrier wave 2, so the RTT time is declined due to allowing to retransmit for carrier wave 1.For carrier wave 2, the links-and-links machine due to limiting Ack can only on carrier 1, can cause the sub-frame of uplink waste of this carrier wave, so comparing non-carrier polymerization, the RTT time can increase.

Fig. 6 is another schematic diagram of the data transmission and reception sequential relationship of multicarrier frame configuration, the main distinction of Fig. 6 and Fig. 5 is, in the data transmission and reception sequential relationship of multicarrier frame configuration shown in fig. 6, ACK message can be fed back on carrier wave 1 and carrier wave 2, therefore, the RTT time of all processes is all 8ms, to reduce time delay.

According to the HARQ sequential relationship for the available multicarrier frame configuration of data transmission and reception sequential relationship that multicarrier frame configures, the HARQ timing of multicarrier frame configuration refers to receiving end feeding back ACK/NACK message sequential relationship over a number of carriers, table 1 is a kind of schematic diagram of the HARQ sequential relationship of multicarrier frame configuration, example shown in table 1, in CC x (x=0, 1) CC y (y=0 is replied on the PUCCH of subframe n, 1) for the PDSCH of subframe n-k, it is described from transmitting terminal, k indicates that transmitting terminal sends the sub-frame interval of TB to the feedback message for receiving the TB, it is described from receiving end, k indicates that receiving end receives the sub-frame interval of TB to the feedback message for sending the TB.

Table 1

It is illustrated so that the frame of CC1 and CC2 is configured to 2+2 as an example, 2+2 indicates that CC1 and CC2 uses frame to configure 2.Assuming that the second equipment receives the TB of the first equipment transmission in the subframe 2 of CC1, then the second equipment can be used CC2 and CC1 and send ACK/NACK message to the first equipment.When the second equipment sends ACK/NACK message to the first equipment using CC1, then the second equipment needs to send ACK/NACK message to the first equipment after the subframe 2 of CC1 is spaced 6 subframes or 4 subframes；When the second equipment sends ACK/NACK message to the first equipment using CC2, then the second equipment needs to send ACK/NACK message to the first equipment after the subframe 2 of CC2 is spaced 6 subframes, 5 subframes or 4 subframes.Assuming that the second equipment receives the TB of the first equipment transmission in the subframe 2 of CC2, then the second equipment can be used CC2 or CC1 and send ACK/NACK message to the first equipment.When the second equipment sends ACK/NACK message to the first equipment using CC1, then the second equipment needs to send ACK/NACK message to the first equipment after the subframe 2 of CC1 is spaced 6 subframes or 5 subframes；When the second equipment sends ACK/NACK message to the first equipment using CC2, then the second equipment needs to send ACK/NACK message to the first equipment after the subframe 2 of CC2 is spaced 6 subframes.

Above-mentioned described from receiving end, when describing from transmitting terminal, it is assumed that the first equipment has sent TB to the second equipment in the subframe 2 of CC1, then the first equipment can receive second on CC1 or CC2 The ACK/NACK message for the TB that equipment is sent.When the first equipment receives the ACK/NACK message of the TB on CC1, the first equipment needs to be spaced 6 subframes in the subframe 2 of CC1 or 4 subframes are followed by receiving the ACK/NACK message of the first equipment transmission；When the first equipment is in the ACK/NACK message of the CC2 TB, the first equipment, which needs to be spaced 6 subframes, 5 subframes or 4 subframes in the subframe 2 of CC2, to be followed by receiving the ACK/NACK message of the first equipment transmission.Assuming that the first equipment has sent TB to the second equipment in the subframe 2 of CC2, the first equipment can also receive the ACK/NACK message of the TB of the second equipment transmission on CC1 or CC2.When the first equipment receives the ACK/NACK message of the TB on CC1, first equipment needs to be spaced 6 subframes in the subframe 2 of CC1 or 5 subframes are followed by receiving the ACK/NACK message of the TB, when the first equipment needs to receive the ACK/NACK message of the TB on CC2, the first equipment, which needs to be spaced 6 subframes in the subframe 2 of CC2, to be followed by receiving the ACK/NACK message of the TB.

By above-mentioned table 1 it is found that since ACK/NACK message can be sent on two carrier waves, to reduce RTT time delay.It should be noted that table 1 is a schematic diagram, therefore the value of k may be different with actual conditions.

In the present embodiment, the first equipment can be determined whether by following following several modes using multicarrier HARQ mode:

(1) first equipment judges whether have propagation delay time to require the business for being less than delay threshold in the business of current transmission.When there is propagation delay time to require to be less than the business of delay threshold in the business of current transmission, the first equipment, which determines, uses multicarrier HARQ mode.

Wherein, the propagation delay time of some business requires to be less than delay threshold, illustrate that the business is more demanding to time delay, if using single carrier HARQ mode, since the first biography of data and re-transmission can only be on the same carrier waves, and ACK/NACK feedback can only be on main carrier, data transmission delay is caused to increase, therefore, the first equipment, which determines, uses multicarrier HARQ mode, under multicarrier HARQ mode, data transmission delay can be reduced.

(2) first equipment judge whether current signal is lower than snr threshold, and when current signal is lower than snr threshold, the first equipment, which determines, uses multicarrier HARQ mode.

First equipment can count signal-to-noise ratio according to the reception result of data, and in general, signal-to-noise ratio is bigger, illustrates that the noise being mixed in signal is smaller, and opposite signal-to-noise ratio is smaller, illustrates that the noise being mixed in signal is bigger.Signal-to-noise ratio is lower than snr threshold, illustrates that noise is very big, channel quality is bad.By supporting the HARQ mode of multicarrier, the sub-frame of uplink number that UE is supported increases, thus on increasing Row covering, increases the signal-to-noise ratio of uplink.

(3) first equipment judge whether current Block Error Rate is greater than Block Error Rate threshold value, and when current Block Error Rate is greater than Block Error Rate threshold value, the first equipment, which determines, uses multicarrier HARQ mode.

Block Error Rate refers to the percentage that the block that malfunctions is shared in the block of all transmissions in data block that transmitting terminal is sent, Block Error Rate is bigger to illustrate that channel quality is poorer, by the HARQ mode for supporting multicarrier, so that UE has more ascending channel detecting reference signals (Sounding Reference Signal, abbreviation SRS) transmission opportunity, so that base station more accurately obtains channel information, to improve transmission reliability, Block Error Rate is reduced.

Step 102, the first equipment send instruction message to the second equipment, which is used to indicate the second equipment and is switched to multicarrier HARQ mode.

The HARQ sequential relationship for the multicarrier frame configuration that in the present embodiment, under multicarrier HARQ mode, the HARQ sequential relationship of at least one multicarrier frame configuration is all stored in the first equipment and the second equipment, also, is stored in the first equipment and the second equipment is identical.

It should be noted that, in other embodiments of the present invention, it can also be determined by the second equipment and use multicarrier HARQ mode, and request message is sent to the first equipment, first equipment receives the request message that the second equipment is sent, the request message is switched to multicarrier HARQ mode for requesting, if the first equipment allows to be switched to multicarrier HARQ mode, then the first equipment can send confirmation message to the second equipment, first equipment can not also send confirmation message, and the second equipment defaults the first equipment after a certain time allows to be switched to multicarrier HARQ mode.

Step 103, the first equipment send TB to the second equipment using the subframe n of first carrier.

In the present embodiment, when the first equipment needs to send TB, the first equipment sends TB to the second equipment using the subframe n of first carrier according to scheduling rule, selection.Specifically, first equipment is after determining first carrier and subframe n, process number is distributed for the TB, the TB and the process number are issued to physical layer, the process number is put into the Downlink Control Information (Downlink Control Information, abbreviation DCI) of the TB by physical layer, which is put into Physical Downlink Shared Channel (Physical Downlink Shared Channel, abbreviation PDSCH) on, then the TB and DCI is sent on the subframe n of first carrier.

Step 104, the second equipment determine the subframe m for the second carrier wave that the feedback message for sending TB uses according to the HARQ sequential relationship for receiving first carrier, subframe n and the configuration of multicarrier frame that TB is used.

Second equipment receives data on the subframe n of first carrier, and the second receiving device reads DCI from the data received, reads TB according to DCI, and the TB is put into the corresponding caching (buffer) of process according to the process number in DCI.Then, the second equipment determines the subframe m for the second carrier wave that the feedback message for sending TB uses according to the HARQ sequential relationship for receiving first carrier, subframe n and the configuration of multicarrier frame that TB is used.Optionally, each carrier wave in the HARQ sequential relationship of multicarrier configuration can send the feedback message of TB, it is not identical to the scheme of the prior art, the feedback information of the TB sent in main carrier and secondary carrier in the prior art can only all be sent on main carrier, in the present embodiment, secondary carrier can be used for sending the feedback information of TB, i.e., the feedback information of the TB sent on main carrier can also be sent in secondary carrier.Alternatively, only some carrier wave can send the feedback message of TB in the HARQ sequential relationship of multicarrier configuration.When each carrier wave in the HARQ sequential relationship of multicarrier configuration can send the feedback message of TB, the second carrier wave and first carrier may be identical, it is also possible to different.When first carrier and identical the second carrier wave, first carrier and the second carrier wave are all main carrier or are all secondary carrier；When first carrier and the second carrier wave difference, first carrier can be main carrier, and the second carrier wave is secondary carrier, can also be using first carrier as secondary carrier, and the second carrier wave is main carrier.

For the example shown in the table 1, the HARQ sequential relationship of 5 multicarrier frames configuration is stored in table, the second equipment determines the HARQ sequential relationship that a multicarrier frame configures from the HARQ sequential relationship that 5 multicarrier frames configures.Second equipment can determine the HARQ sequential relationship of the multicarrier frame configuration used according to the delay requirement of TB.Assuming that the second equipment has determined the HARQ sequential relationship configured using 2+2 multicarrier, and second equipment be to have received the TB in the subframe 7 of CC1, i.e. first carrier is CC1, subframe n is subframe 7, the HARQ sequential relationship so configured according to multicarrier frame, second equipment can be used CC1 and CC2 and send feedback message, further according to the resource service condition of CC1 and CC2, determine that CC1 or CC2 sends feedback message, assuming that the second equipment, which is determined, sends feedback message to the first equipment after the subframe 7 of CC2 is spaced 4 subframes, so the second carrier wave is CC2, subframe m is the subframe 1 of next radio frames of CC2.

Step 105, the second equipment send the feedback message of TB using the subframe m of the second carrier wave to the first equipment.

The data that second equipment interconnection receives are detected, if received correctly, which is ACK message, if receiving mistake, which is NACK message.

Step 106, when the feedback message of TB be ACK message when, the first equipment determine TB transmit Success, the first equipment send next TB, and when the feedback message of TB is NACK message, the first equipment determines TB transmission failure.

Step 107, the first equipment retransmit TB using the subframe j of third carrier wave.

Step 107 is optional step, when feedback information is ACK message, does not need to execute step 107, when feedback message is NACK message, just needs to be implemented step 108.

After first equipment sends TB on the subframe n of first carrier, the feedback message of TB is received on the subframe m of the second carrier wave, before the feedback message for receiving TB, first equipment is according to the HARQ sequential relationship for sending first carrier, subframe n and the configuration of multicarrier frame that TB is used, determine the subframe m for the second carrier wave that the feedback message for receiving TB uses, wherein, the first equipment and the second equipment determine that the second carrier wave is identical with the method for subframe m, and which is not described herein again.

It should be noted that under carrier aggregation scene, the first equipment can be used any one of multiple carrier waves and retransmit TB, and therefore, third carrier wave may be identical with first carrier, it is also possible to different with first carrier in the embodiment of the present invention.Can only be on the same carrier wave different from the prior art, retransmitting TB and first biography TB, it cannot cross-carrier re-transmission TB.In compared with the prior art, the method of the embodiment of the present invention, due to can cross-carrier re-transmission TB, if some carrier wave ratio just passes the carrier wave that uses of TB and has more send opportunity, so the first equipment can be used the carrier wave and be retransmitted, and be further able to reduce the propagation delay time of data.

When retransmitting the TB, first equipment will not redistribute process number for the TB, the TB is also using the process number of the first equipment distribution when just passing, process number is put into DCI by the first equipment, the redundancy versions 1 of DCI and TB are sent on the subframe j of third carrier wave, a TB may will do it multiple re-transmission, and maximum retransmission as defined in agreement is 4 at present, in order to distinguish the TB being transmitted several times, redundancy versions are introduced.Usually when just passing the TB, what is sent on the subframe n of first carrier is the redundancy versions 0 of DCI He the TB, and what when later retransmission sent is the redundancy versions 3, redundancy versions 2 and redundancy versions 1 of the TB.

The processing operation of the re-transmission of the subsequent TB is all identical with processing operation when first pass, which is not described herein again, certainly retransmitting for the first time may also fail, and retransmit if having failed and carrying out second according to the above process, and the processing operation retransmitted every time is that identical which is not described herein again.

In the present embodiment, by introducing the HARQ timing of multicarrier frame configuration, so that the second equipment can be used any one carrier wave and send feedback message under carrier aggregation scene, the chance of feedback message is sent to increase the second equipment, and then data transmission delay can be reduced.And the first equipment exists When retransmitting TB, different carrier waves can be used from the TB is just passed, to increase the send opportunity for retransmitting TB, further reduced data transmission delay.

Fig. 7 be multicarrier provided by Embodiment 2 of the present invention under data transmission method, as shown in fig. 7, method provided in this embodiment the following steps are included:

The carrier identification and the second time quantum for the second carrier wave that the feedback message for the TB that step 201, the first equipment are sent from the first time unit for determining first carrier in multiple carrier waves uses.

Different from embodiment one, the concept and HARQ sequential relationship of frame configuration are not present in the application scenarios of the present embodiment, i.e., each carrier wave does not have fixed HARQ sequential relationship.There may be following three kinds of subframe types for each carrier wave:

(1) downlink subframe；All symbols in subframe are all downlink symbol；

(2) sub-frame of uplink: all symbols in subframe are all uplink symbol；

(3) two-way subframe: the symbol in subframe includes uplink symbol and downlink symbol, and the ratio of uplink symbol and downlink symbol can configure.

It is likely to that there are these three subframe types on each carrier wave.On some carrier wave, which kind of subframe type some specific time uses, and is determined by the scheduling message of base station.

Since there is no fixed HARQ sequential relationship in the present embodiment, therefore, it is uniformly scheduled by the first equipment, first equipment is in the carrier wave and time quantum that the feedback message for determining TB uses, the mark and the second time quantum of the second carrier wave that can be used according to the second equipment the whether idle feedback message for determining TB of the time quantum on the processing time and each carrier wave of TB, wherein, when the first equipment is base station, second equipment is UE, and when the first equipment is UE, the second equipment is base station.Due to the HARQ sequential relationship that do not fix, for the TB sent on same carrier wave and time quantum, the carrier wave and time quantum that determining feedback message uses every time may be different, so that the transmission of data is more flexible.

In the present embodiment, first carrier and the second carrier wave may it is identical may also be different.The first time unit of first carrier is for sending TB, and therefore, the first time unit of first carrier can be downlink subframe or two-way subframe, and the downlink symbol in two-way subframe is for sending TB.Second time quantum of the second carrier wave is used to send the feedback message of TB, therefore the second time quantum of the second carrier wave can be sub-frame of uplink or two-way subframe, and the uplink symbol in two-way subframe is used to send the feedback message of TB.

The method of the present embodiment can be applied in CA scene, and the prior art is in CA scene, and the feedback information of the TB sent on main carrier and secondary carrier can only all be sent on main carrier, and this reality The feedback message of TB can be sent by applying each carrier wave in the method for example in multiple carrier waves, i.e., the feedback information of the TB sent on main carrier can also be sent in secondary carrier.When first carrier and the second carrier wave difference, first carrier can be main carrier, and the second carrier wave is secondary carrier, can also be using first carrier as secondary carrier, and the second carrier wave is main carrier.

Step 202, the first equipment send instruction information to the second equipment, which is used to indicate the feedback message that the second equipment sends TB on the second time quantum of the second carrier wave.

The information of mark and the second time quantum in the instruction information including the second carrier wave, the information of the second time quantum can be subframe numbers or sub-frame offset.The instruction information can carry in the control information of TB.Certainly, which can also be sent by individual message, and the present invention limits not to this.

Step 203, the first equipment send TB to the second equipment using the first time unit of first carrier.

Step 204, the second equipment send the feedback message of TB according to instruction information on the second time quantum of the second carrier wave to the first equipment.

The data that first equipment interconnection receives are detected, if received correctly, which is ACK message, if receiving mistake, which is NACK message.If the information of the second time quantum is the offset of subframe, the second equipment obtains sending the serial number m of the subframe of feedback information according to the serial number n of current subframe and the offset of subframe.If the information of the second time quantum is sub-frame number, the second equipment sends the feedback message of TB directly in the corresponding subframe of sub-frame number.

The feedback message of step 205, the first equipment TB that the second equipment is sent on the second time quantum of the second carrier wave, when the feedback message of TB is ACK message, second equipment determines TB transmission success, TB sends next TB, when the feedback message of TB is NACK message, second sets determining TB transmission failure.

Step 206, the first equipment retransmit TB using the third time quantum of the third carrier wave in multiple carrier wave.

Under carrier aggregation scene, base station can be used any one of multiple carrier waves and retransmit TB, and therefore, third carrier wave may be identical with first carrier, it is also possible to different with first carrier.Can only be on the same carrier wave different from the prior art, retransmitting TB and first biography TB, it cannot cross-carrier re-transmission TB.In compared with the prior art, the method for the present embodiment, due to can cross-carrier re-transmission TB, if some carrier wave ratio just passes the carrier wave that uses of TB and has more send opportunity, the first equipment be can be used The carrier wave is retransmitted, and is further able to reduce the propagation delay time of data.

In multicarrier scene, high frequency carrier and low frequency carrier signal may be simultaneously present, high frequency carrier transmission rate is high, but high frequency carrier penetrability is weak, is easy to be blocked, and the reliability of communication is poor, and the transmission rate of low frequency carrier signal is slow, but high reliablity.In many cases, in order to guarantee data transmission reliability, can using low frequency carrier signal transmit come auxiliary high frequency transmit.Base station can carry out low-frequency transmission with signaling the different operating mode of UE, such as in the first operating mode, carry out the transmission of low frequency auxiliary high frequency in the second operation mode, carry out high-frequency transmission in a third mode.The following are application scenes:

At UE access high frequency base station, can assist sending the data transmitted on high frequency carrier by low frequency carrier signal, high frequency base station is the base station using high frequency carrier.The frame time difference etc. of the frequency domain position of high frequency synchronization signal, the subcarrier spacing of high frequency synchronization signal, high frequency carrier and low frequency carrier signal can be sent to UE by low frequency base station, wherein, the frequency domain position of high frequency synchronization signal is for UE when accessing high frequency base station, directly acquire high frequency synchronization signal, high frequency synchronization signal is obtained without blind Detecting, synchronization can be fast implemented convenient for UE.The subcarrier spacing of high frequency synchronization signal when accessing high frequency base station, directly acquires the subcarrier spacing of high frequency synchronization signal for UE, is not necessarily to blind Detecting.The time difference of high frequency carrier and low frequency carrier signal, by the initial time of the frame of low frequency carrier signal, obtains the initial time of the frame of high frequency carrier for UE.UE obtains the time difference of the frequency domain position of high frequency synchronization signal, the subcarrier spacing of high frequency synchronization signal, high frequency carrier and low frequency carrier signal by low frequency carrier signal, UE is avoided when accessing high frequency base station, above- mentioned information are obtained by blind Detecting, lead to the problem that turn-on time is long, while also increasing reliability.

In synchronizing process, base station sends synchronization signal to UE by wave beam, UE need to obtain synchronization signal where the corresponding symbolic number of wave beam, symbolic number determines the position of current sign for UE.In the case where no low frequency auxiliary, UE can obtain the symbolic number of high frequency in the following way: (1) different symbols is indicated by frequency offset amount, wherein, different symbols corresponds to primary synchronization signal (Primary Synchronization Signal, abbreviation PSS) and secondary synchronization signal (Secondary Synchronization Signal, abbreviation SSS) difference frequency domain offset, therefore symbol can be determined according to frequency offset amount；(2) different symbols corresponds to different synchronizing sequences, determines symbol by synchronizing sequence.In the case where there is low frequency auxiliary, UE can release the frame boundaries of high frequency by the frame time difference of high frequency carrier and low frequency carrier signal.At this point, for high frequency carrier, due to being proposed the frame boundaries of high frequency, in the case where there is low frequency auxiliary, the quantity phase of the frequency offset amount needed in scheme (1) Reduce in the case where compared with no low frequency auxiliary, the quantity for the synchronizing sequence that scheme (2) needs reduces in the case where assisting compared to no low frequency, such as, in the case where no low frequency auxiliary, indicate that 10 symbols need 10 frequency offset amounts, and in the case where there is low frequency auxiliary, indicate that 10 symbols may only need 2 frequency offset amounts.Since the frequency offset amount and synchronizing sequence of use reduce, to reduce the complexity that base station sends synchronization signal.The limited frequency offset amount of use or limited synchronizing sequence are issued UE by low frequency by base station, and UE can further determine that symbolic number.

The frame border time that base station can voluntarily measure high and low frequency by signaling instruction UE is poor, and UE can be by determining that symbolic number be inferred to the time difference, and measurement result is reported to base station.Base station determines the Timing Advance that UE uplink is sent in conjunction with communicating back the time between low-and high-frequency according to the time difference.

Behind UE access high frequency base station, normal communication periods can carry out wave beam management and measurement by low frequency carrier signal auxiliary high frequency base station.UE can be based on state information reference signals (Channel State Information Reference Signal, abbreviation CSI-RS) measure channel state information (Channel State Information, abbreviation CSI), and to base station feedback CSI, to realize scheduling of the base station to UE.Before measuring, high frequency base station needs for measurement configuration information to be sent to UE to UE, and in the method for the present embodiment, measurement configuration information can be sent to low frequency base station by high frequency base station, and measurement configuration information is sent to UE by low frequency carrier signal by low frequency base station.The measurement configuration information includes time of measuring and measurement frequency range etc..After UE completes measurement, measurement result is sent to low frequency base station by low frequency carrier signal, measurement result is transmitted to high frequency base station again by low frequency base station, the measurement result may include wave beam mark, Reference Signal Received Power (Reference Signal Receiving Power, abbreviation RSRP), CSI, signal quality, signal strength etc..

High frequency base station mostly uses Beamforming technology to increase coverage area and improve communication quality.When the high-frequency link where high frequency carrier is interrupted, in order to restore high-frequency link, UE, which needs to send wave beam to high frequency base station, repairs request message, in the present embodiment, UE sends wave beam reparation request to high frequency base station by low frequency carrier signal, and UE requests the wave beam reparation to be sent to low frequency base station by low frequency carrier signal, wave beam reparation request is sent to high frequency base station again by low frequency base station, to guarantee the reliability of wave beam reparation request, in order to which base station requests timely to reselect wave beam for UE according to the wave beam reparation.Similarly, UE can send wave beam to high frequency base station by low frequency carrier signal and track solicited message, to guarantee the reliability of wave beam tracking request, in order to which base station operates in time for the UE tracking for carrying out wave beam according to wave beam tracking request.

It should be noted that above-described embodiment is only with high frequency carrier and low frequency carrier signal for example, actually the above method is suitable between any two carrier wave, for example, applying between first carrier and the second carrier wave, first carrier and the second carrier wave are different carrier waves.
