Fig. 1 shows the indicative flowchart of the method 100 of transmission signal according to embodiments of the present invention, and this method 100 can be performed by the network equipment of such as base station or other network access equipments.As shown in figure 1, this method 100 includes:
S110, dispatch is sent to user equipment, and the dispatch includes the frequency resource information distributed for the user equipment, and the frequency resource information is used to indicate Physical Resource Block PRB;
S120, on reserved resource unit RE in the PRB, interferometry reference signal IMRS is sent in order to which the user equipment determines interference information according to being measured to the IMRS to the user equipment, and sends downlink data signal to the user equipment on the PRB;Or
On S130, the reserved RE in the PRB, the IMRS of user equipment transmission is received, interference information is determined according to being measured to the IMRS, and receive on the PRB upstream data. signals of user equipment transmission;
Wherein, the quantity of the reserved RE in each PRB is identical.
Therefore, the method of transmission signal according to embodiments of the present invention, by before transmission data-signal, transmit interferometry reference signal, so that the interference being subject to during signal transmission can be estimated exactly, suitable receiver parameters or adjustment scheduling scheme are so can determine that, so as to strengthen the performance of signal transmission, Consumer's Experience is improved.
Specifically, in LTE systems, a Transmission Time Interval(Transmission Time
Interval, cylinder is referred to as " Τ Τ Γ) length be lms, and can generally include 14 OFDMs(Orthogonal Frequency Division Multiplexing, cylinder is referred to as " OFDM ") symbol;Divided for unit, each PRB can include 12 subcarriers on frequency domain;Each subcarrier on temporal each symbol and frequency is most basic transmission unit, is referred to as a resource unit (Resource Element, cylinder is referred to as " RE ").
In current LTE system, for downlink transfer, the network equipment is that (n is nonnegative integer to n in numbering)TTI to UE send dispatch(Such as Physical Downlink Control Channel in LTE system(Physical Downlink Control Channel, cylinder is referred to as " PDCCH ")), wherein can include network equipment indicating downlink transmits the Modulation and Coding Scheme used(Modulation and Coding Scheme, cylinder is referred to as " MCS "), for the number of plies etc. of the UE downstream frequency resources distributed and space propagation Information.Correspondingly, the network equipment is just according to the corresponding code rates of the MCS and modulation system on the Τ, the information bit for being sent to user equipment is encoded and modulated, then can carrying out layer map operation to the signal after modulation according to the number of plies of space propagation, (it is simultaneous transmission multi-stream data to be mapped to multilayer), finally send downlink data signal in corresponding downstream frequency resource(That is Physical Downlink Shared Channel(Physical Downlink Shared Channel, cylinder is referred to as " PDSCH ")).
And for the method for transmission signal according to embodiments of the present invention, in downlink transfer, the network equipment can be that (n is nonnegative integer to n in numbering)TTI to UE send dispatch, the dispatch includes the descending PRB that the network equipment is that user equipment (UE) is distributed, and the scheduling signals can also include the network equipment and indicate to transmit the information such as the MCS that use, the antenna port that the number of plies of transmission or transmission are used;The network equipment can send interferometry on the reserved RE in the descending PRB distributed for UE and refer to letter-(Interference Measurement Reference Signal, cylinder is referred to as " IMRS "), in order to the other UE for the identical PRB that has been scheduled (cylinder claims " other UE "), the network equipment is obtained by measuring the IMRS and is sent to interference of the signal of the UE to other UE, for example, measures the intensity of interference or calculates Signal to Interference plus Noise Ratio(Signal to Interference-plus-Noise Ratio, cylinder is referred to as " SINR ");Afterwards, the network equipment can be on the PRB to user equipment transmission downlink data signal.Especially, the PRB overlapping with the UE parts other UE of being scheduled can also obtain the benefit that the present invention is brought, and repeat no more below.
I.e. in embodiments of the present invention, each UE can not detect PDSCH immediately after dispatch is received, but first can be gone to measure IMRS according to dispatch, to obtain accurate interference information.For example, as shown in Fig. 2 the identical PRB that has been scheduled UE1 and UE2 receive PDSCH from the network equipment 1 and the network equipment 2 respectively;Because UE1 and UE2 have been scheduled identical PRB, then the network equipment 1 is sent to UE1 PDSCH and UE2 can be interfered, thus UE2 is after the dispatch of the transmission of the network equipment 2 is received, PRB information that can be first in dispatch, detects the IMRS that the network equipment 2 is sent on corresponding PRB.Because the network equipment 1 can also send IMRS on corresponding PRB, therefore UE2 on these PRB when detecting the IMRS that the network equipment 2 is sent, equally can by the network equipment 1 interference.In addition, because the network equipment 1 and 2 sends IMRS on these PRB simultaneously, the network equipment 1 and 2 can also send PDSCH simultaneously on these PRB, therefore, the interference that UE2 measurements IMRS is subject to similarly is to receive the interference being subject to during PDSCH, it is also in this way, and example when can be extended to the more than two network equipment for UE1.
Therefore, because IMRS is sent prior to PDSCH, so that UE can just received
Disturbed condition is known before PDSCH in advance, just UE first such as can be determined in advance according to the disturbed condition PDSCH receiver coefficient is received, so as to reach the effect of quick detection;Or the disturbed condition can also be fed back to the network equipment by UE, in order to which the network equipment adjusts the scheduling to UE, for example, MCS is adjusted, to adapt to the disturbed condition.
In current LTE system, for uplink, the network equipment is numbering the TTI for being n to UE transmission dispatch, and the information such as number of plies of MCS, the upstream frequency resource for UE distribution and transmission that uplink is used are indicated including the network equipment.Correspondingly, UE is just according to the corresponding code rates of the MCS and modulation system on n+4 Τ in numbering after receiving the dispatch, the information bit for being sent to the network equipment is encoded and modulated, then layer mapping is carried out according to the number of plies of transmission, that is the signal after 4 bars modulation is mapped as at least one layer of data, finally sends Physical Uplink Shared Channel in corresponding upstream frequency resource(Physical Uplink Shared Channel, cylinder is referred to as " PUSCH ");The network equipment is also that on n+4 Τ, the PUSCH that UE is sent is received in corresponding upstream frequency resource in numbering.
And for the method for transmission signal according to embodiments of the present invention, in uplink, the network equipment is that (n is nonnegative integer to n in numbering)Τ to UE send dispatch, the dispatch is, for example, PDCCH, the dispatch can be the up PRB that user equipment (UE) is distributed including the network equipment, and the scheduling signals can also include the network equipment and indicate to transmit the information such as the MCS that use, the antenna port that the number of plies of transmission or transmission are used;The network equipment can be on the reserved RE in the up PRB distributed for UE, receive the IMRS that user equipment (UE) is sent, and the other network equipments for the identical PRB that has been scheduled are sent to interference of the signal of the network equipment to other network equipments by measuring the IMRS with regard to that can obtain the UE;Afterwards, the network equipment can receive the upstream data. signals of user equipment transmission on the PRB.
Because IMRS is sent prior to PUSCH, so as to which the network equipment can just know disturbed condition in advance before PUSCH is received, just for example first it can determine that the network equipment receives PUSCH receiver coefficient in advance according to the disturbed condition, so as to reach the effect of quick detection;Or the network equipment can also send Dispatching adjustment signaling to UE, to adjust the scheduling to UE, such as MCS adjusted, so as to adapt to the disturbed condition according to the disturbed condition for receiving IMRS and knowing.
Therefore, the method of transmission signal according to embodiments of the present invention, by before transmission data-signal, transmit interferometry reference signal, so that the interference being subject to during signal transmission can be estimated exactly, suitable receiver parameters or adjustment scheduling scheme are so can determine that, so as to strengthen the performance of signal transmission, Consumer's Experience is improved.
In embodiments of the present invention, for downlink transfer, it is assumed that the network equipment is n's in numbering Dispatch is sent in TTI, then the delivery time that the network equipment sends IMRS can be other Τ Τ Ι after the Τ Τ Ι or the Τ Τ Ι that the numbering is η;Another sunset is foretold, and PDSCH delivery time is after IMRS delivery time.But for uplink, user equipment needs some times to carry out the control signaling of decoding network equipment transmission, and therefore, other TTI that the network equipment can be after sending control signaling receive the IMRS that user equipment is sent.Below only to send IMRS in the TTI that numbering is n, and illustrated exemplified by the 4th TTI after IMRS is sent sends PDSCH, but the embodiment of the present invention is not limited to this.
It should be understood that in embodiments of the present invention, the network equipment is that the frequency resource information that each user equipment is distributed can indicate one or more PRB, and the quantity of the reserved RE in each PRB is identical.For example, the quantity that the network equipment sends the reserved RE in multiple dispatch, each PRB indicated by the frequency resource information included for each dispatch, these PRB to user equipment is identical;In another example, the quantity that multiple user equipmenies of the network equipment into cell send the reserved RE in dispatch, each PRB indicated by the frequency resource information included for each dispatch, these PRB is also identical.Thereby, it is possible to estimate the interference being subject to during signal transmission exactly, so as to determine suitable receiver parameters or adjustment scheduling scheme, the performance of enhancing signal transmission improves Consumer's Experience.

Alternatively, in embodiments of the present invention, this sends interferometry reference signal IMRS to the user equipment, including:On same subcarrier or same symbol in the PRB, use and the IMRS is sent to the user equipment with the orthogonal resource of code division mode;Or
The IMRS that the reception user equipment is sent, including:The user equipment is received on the same subcarrier or same symbol in the PRB, the IMRS sent with the orthogonal resource of code division mode is used. When Fig. 6 A show downlink transfer, the schematic block diagram of transmission IMRS according to embodiments of the present invention running time-frequency resource, wherein sending IMRS resource using the orthogonal orthogonal manner of code division by least two antenna ports.As shown in Figure 6A, for the RE in any PRB with (k, t) represent, wherein k and t represent the relative numbering of subcarriers and symbol of the RE in the PRB respectively, for example, 4 RE for being used to transmit IMRS in Fig. 6 A are RE (9 respectively, 5), RE (9,6), RE (9,9) and RE (9,10).In embodiments of the present invention, the IMRS that code division orthogonal representation different antennae port is sent uses 4 RE in identical RE, but different orthogonal codes, Fig. 6 A to be used to transmit IMRS, the orthogonal code that length is 4 can be then used, the orthogonal code is, for example, Walsh(Walsh) code etc..Preceding Ns (Ns=2 in figure) individual symbol that Fig. 6 A also show in the Τ of dispatch domain and data field, i.e., one be used to send dispatch PDCCH, and other symbols can be used to send data-signal PDSCH.
In embodiments of the present invention, the IMRS that the transmission of different antennae port is distinguished by the orthogonal mode of code division is advantageous in that:For the UE of a certain network device services, no matter other network equipments send IMRS by several antenna ports, UE can be measured on these RE and be obtained the interference that these all IMRS are caused.For example shown in Fig. 2, the network equipment 1 and 2 sends IMRS by 2 and 4 antenna ports respectively, the IMRS that the IMRS and the network equipment 2 sent due to the network equipment 1 by any antenna port is sent by any antenna port occupies identical RE, then UE1 is when these RE are measured, the IMRS that all antenna ports of the suffered interference from the network equipment 2 are sent, therefore, UE1 just can measure the interference for obtaining all antenna ports from the network equipment 2;Similarly, for UE2, UE2 can also measure the interference for obtaining all antenna ports from the network equipment 1.Therefore, by the orthogonal method of the code division, user equipment can blunt easy measurement obtain in the case of various antenna ports needed for interference information.
When Fig. 6 Β show uplink, the schematic block diagram of transmission IMRS according to embodiments of the present invention running time-frequency resource, wherein sending IMRS resource using the orthogonal orthogonal manner of code division by least two antenna ports.As shown in Figure 6B, wherein being used to transmit IMRS RE includes the even subcarriers of last symbol, 6 RE be used to transmit IMRS in figure, the orthogonal code that length is 6 can then be used, the orthogonal code can include cyclic shift known to industry (cyclic shift), different cyclic shifts are loaded to same sequence, are orthogonal between the new sequence generated with guarantee.Equally, by the orthogonal method of the code division, the network equipment can be easy to measure the interference information needed for obtaining in the case of various antenna ports.
Especially, in a PRB, the decline of distinct symbols is more close on same subcarrier, and on same symbol different sub-carrier decline it is also more close, and an orthogonal premise of code division is just It is to need the corresponding channel fadings of correlation RE essentially identical, therefore, it is used to transmit IMRS using the RE on same subcarrier or same symbol, so that the IMRS that different antennae port is sent is noiseless each other, so as to further enhance the effect that code division is orthogonal, the performance of signal transmission is further enhanced, Consumer's Experience is improved.
In embodiments of the present invention, alternatively, this sends interferometry reference signal to the user equipment
IMRS, including:Used in the PRB and the IMRS is sent to the user equipment with the orthogonal resource of frequency division code division mode;Or
The IMRS that the reception user equipment is sent, including:Receive the user equipment and the IMRS sent with the orthogonal resource of frequency division code division mode is used in the PRB.
Specifically, when Fig. 7 A show downlink transfer, the schematic block diagram of transmission IMRS according to embodiments of the present invention running time-frequency resource, wherein sending IMRS resource using the orthogonal orthogonal manner of frequency division code division by least two antenna ports.
As shown in Figure 7 A, 4 RE for transmitting IMRS are RE (9 respectively, 5), RE (9, 6), RE (3, 5) with RE (3, 6), wherein the network equipment can be in RE (9, 5) with RE (9, 6) the 1st ~ 2 corresponding IMRS of antenna port is transmitted on, and can be in RE (3, 5) with RE (3, 6) the 3rd ~ 4 corresponding IMRS of antenna port is transmitted on, between wherein the 1st antenna port and the 2nd antenna port, or realized between the 3rd antenna port and the 4th antenna port by code division orthogonal, orthogonal code a length of 2.The orthogonal IMRS for representing that different antennae port is sent of code division uses identical RE but different orthogonal codes, for example, the corresponding RE of IMRS that the 1st, 2 antenna ports are sent are identical, but orthogonal code is different.For example shown in Fig. 2, the network equipment 1 and 2 all sends IMRS by 4 antenna ports, and the RE that the two network equipments are used is identical, then can measure interference.
Specifically, when Fig. 7 B show uplink, the schematic block diagram of transmission IMRS according to embodiments of the present invention running time-frequency resource, wherein sending IMRS resource using the orthogonal orthogonal manner of frequency division code division by least two antenna ports.As shown in Figure 7 B, the even subcarriers of last symbol are included for transmitting IMRS RE, wherein the subcarrier that numbering is 0,4,8 is used for transmission the 1st, 2 corresponding IMRS of antenna port;The subcarrier that numbering is 2,6,10 is used for transmission the 3rd, 4 corresponding IMRS of antenna port, wherein, 1st, the IMRS that 2 antenna ports are sent is distinguished by orthogonal code, and the 3rd, the IMRS that sends of 4 antenna ports distinguishes also by orthogonal code.Similarly, by the orthogonal method of the frequency division code division, can the blunt easy measurements of ^ obtain in the case of various antenna ports needed for interference information.
In the orthogonal embodiment of the frequency division code division as shown in Fig. 7 Α and 7 Β, the network equipment or user set Interference of the IMRS that the standby all antenna ports that can not simulate adjacent cell are sent to the IMRS of this cell.For example, as shown in Figure 1, the network equipment 1 and 2 all sends IMRS by 4 antenna ports, because the two network equipments are all in RE (9, 5) with RE (9, 6) the 1st is passed through on, 2 antenna ports send IMRS, and in RE (3, 5) with RE (3, 6) the 3rd is passed through on, 4 antenna ports send IMRS, then UE1 is in RE (9, 5) with RE (9, 6) when obtaining interference information by measuring IMRS on, the network equipment 2 only can be measured by the 1st, 2 antenna ports send the interference caused by IMRS, it will not measure by the 3rd, 4 antenna ports send the interference that signal is caused, so as to which the interference result that UE1 measurements can be caused to obtain is inaccurate.
In order to which Slow solves above mentioned problem, in embodiments of the present invention, alternatively, this sends interferometry reference signal IMRS to the user equipment, including:When the quantity of the antenna port included at least two antenna port is orthogonal code length, or when the quantity of the antenna port is the integral multiple of quantity for the RE that orthogonal code is occupied in the PRB, the IMRS is sent to the user equipment with the first transmit power, wherein, first transmit power is the integral multiple of the second transmit power, second transmit power is when the quantity of the antenna port is not orthogonal code length, or when the quantity of the antenna port is not the integral multiple of quantity for the RE that orthogonal code is occupied in the PRB, the transmit power that the IMRS is used is sent to the user equipment;Or
The IMRS that the reception user equipment is sent, including:Receive the IMRS that the user equipment is sent with the 3rd transmit power, wherein, the quantity for the antenna port that at least two antenna port includes is orthogonal code length, or the integral multiple for the quantity that the quantity of the antenna port is the RE that orthogonal code is occupied in the PRB, wherein, 3rd transmit power is the integral multiple of the 4th transmit power, 4th transmit power is when the quantity of the antenna port is not orthogonal code length, or when the quantity of the antenna port is not the integral multiple of quantity for the RE that orthogonal code is occupied in the PRB, the user equipment sends the transmit power that the IMRS is used.
Specifically, for downlink transfer, when the network equipment sends IMRS antenna port number for K times of orthogonal code lint-long integer, or the RE numbers occupied for orthogonal code in a PRB integer K times when, the transmit power that the network equipment sends IMRS just heightens K times.For example, in the embodiment shown in Fig. 7 A, orthogonal code a length of 2 (orthogonal code also takes up 2 RE in a PRB), if the transmit power that the network equipment is used when sending IMRS by 2 antenna ports is P, then when the network equipment sends IMRS by 4 antenna ports, the transmit power used is 2P.In common communication system, the channel fading difference that all antenna ports of network equipment transmission are undergone is little, then in the above example, if if the network equipment 1 and 2 all passes through transmit power during 4 antenna ports transmission IMRS using 2 times, shellfish, J UE1 measurement RE (3,5) and RE (3,6) interference when by the network equipment 2 is just doubled, so as to allow for The interference that UE1 measurements are obtained is more nearly the interference that 4 antenna ports of the network equipment 2 are caused.
For uplink, similarly, the network equipment receives the IMRS that user equipment is sent with the 3rd transmit power, wherein, the quantity for the antenna port that at least two antenna port includes is orthogonal code length, or the antenna port the integral multiple of RE quantity that is occupied in the PRB for orthogonal code of quantity.
Therefore, the method of transmission signal according to embodiments of the present invention, by before transmission data-signal, transmit interferometry reference signal, so that the interference being subject to during signal transmission can be estimated exactly, suitable receiver parameters or adjustment scheduling scheme are so can determine that, so as to strengthen the performance of signal transmission, Consumer's Experience is improved.
In embodiments of the present invention, alternatively, the reserved RE in the PRB that frequency resource information is indicated includes at least one channel state information reference signals CSI-RS patterns or the corresponding RE of at least one detection reference signal SRS patterns.
Specifically, in LTE system, base station can send CSI-RS pattern numbers to UE, UE is received after the CSI-RS pattern numbers, the RE corresponding to corresponding CSI-RS patterns can be determined according to CSI-RS pattern numbers, so as to which when PDSCH and the CSI-RS pattern of base station scheduling are appeared in a TTI simultaneously, UE will not receive the corresponding RE of CSI-RS patterns as PDSCH, i.e. these RE are not used in transmission PDSCH.During this is done to be easy to other UE to measure these RE channel or interference, the PDSCH's that will not be sent by base station disturbs.CSI-RS pattern number RE corresponding with CSI-RS patterns relation is for example as shown in table 1 below.

19 (2,12) (2,13) are in embodiments of the present invention, it is possible to use above-mentioned design and with compatibility.Because the corresponding RE of IMRS in the embodiment of the present invention are consequently not used for transmitting PDSCH, the reserved RE in the PRB can be just designed as including at least one CSI-RS or corresponding RE of at least one SRS pattern, so as to which using the transmission of CSI-RS pattern numbers or SRS pattern numbers, the RE for being consequently not used for transmitting PDSCH due to transmission IMRS is notified to UE.
For example, in the embodiment shown in Fig. 6 A, the RE resources that IMRS takes are:RE (9,5), RE (9,6), RE (9,9) and RE (9,10), then base station can send (the correspondence RE (9 of CSI-RS pattern numbers 0 of 2 antennas to UE, 5) with RE (9,6)), and (the correspondence RE (9 of CSI-RS pattern numbers 2,9) with RE (9,10));UE would not use these RE to transmit PDSCH after receiving.In another example, in the embodiment shown in Fig. 7 A, IMRS occupies RE (9,5), RE (9,6), RE (3,5) with RE (3,6), then base station can only send (the correspondence RE (9 of CSI-RS pattern numbers 0 of 14 antenna to UE, 5), RE (9,6), RE (3,5) and RE (3,6) these RE would not be used to transmit PDSCH after), then UE is received.
For not supporting IMRS UE, base station can avoid these UE from receiving PDSCH on correspondence RE for the two corresponding IMRS of UE configurations;For supporting IMRS UE, IMRS can also be received on these RE, so as to estimate the interference being subject to during signal transmission exactly, so can determine that suitable receiver parameters or adjustment scheduling scheme, so as to strengthen the performance of signal transmission, Consumer's Experience is improved.
It should be understood that for uplink, the reserved RE in the PRB can also include at least one
The CSI-RS or corresponding RE of at least one SRS pattern, the embodiment of the present invention is only entered with the descending example that is transmitted as Row explanation, but the embodiment of the present invention is not limited to this.
In embodiments of the present invention, when the network equipment or user equipment are less than the quantity of maximum antenna port in the quantity of the antenna port for sending IMRS, the interference for the IMRS that the IMRS that the possibly all antenna ports that can not simulate this cell are sent is sent to adjacent cell.For example, as shown in Figure 2, the network equipment 1 and 2 sends IMRS by 2 and 4 antenna ports respectively, running time-frequency resource schematic diagram according to Fig. 7 A, the network equipment 1 is only in RE (9,5) with RE (9,6) on by the 1st, 1 antenna port send IMRS (in RE (3,5) and IMRS is not sent on RE (3,6)), then the network equipment 2 can be in RE (9,5), RE (9,6) IMRS, is sent by the 1st ~ 4 antenna port on RE (3,5) and E (3,6).Therefore, the IMRS that the network equipment 1 is sent would not to the network equipment 2 by the 3rd, the IMRS that 4 antenna ports are sent interfere, so as to cause UE2 inaccurate in the interference that the IMRS that measurement the 3rd, 4 antenna ports are sent is subject to.
In order to which Slow solves above mentioned problem, in embodiments of the present invention, alternatively, this sends interferometry reference signal IMRS to the user equipment, including:When the quantity of the antenna port for sending the IMRS is less than the quantity of maximum antenna port, repeat to send the IMRS to the user equipment on the reserved RE;Or
The IMRS that the reception user equipment is sent, including:The IMRS that the user equipment repeats to send on the reserved RE is received, wherein, the user equipment sends quantity of the quantity less than the maximum antenna port of the user equipment of the antenna port of the IMRS.
Specifically, for example, in the embodiment shown in Fig. 7 A, if the network equipment sends IMRS by 2 antenna ports, then the network equipment the 3rd, 4 antenna ports send on the corresponding RE of IMRS, can repeat to send the 1st, the IMRS of 2 antenna ports.Now, the running time-frequency resource for the IMRS that the network equipment 1 and 2 is sent can be as shown in Fig. 8 A.Now, the IMRS that are sent to the network equipment 2 by 4 antenna ports of IMRS that the network equipment 1 is sent are interfered so that UE2 can be subject to the IMRS that the network equipment 2 is sent by all 4 antenna ports, the interference that the IMRS that the network equipment 1 is sent by all 2 antenna ports is caused accurately measured.
Herein on basis, because the IMRS that 1 pair of the network equipment is sent by 2 antenna ports is repeated 2 times, then UE1 can just obtain more accurate measurement result when receiving IMRS that these are repeated by average treatment.For example, UE1 measures the IMRS that the network equipment 1 is sent by the 1st antenna port on RE (9,5) and RE (9,6), and calculating obtains Let;And the IMRS that the network equipment 1 is sent by the 1st antenna port can be equally measured on RE (3,5) and RE (3,6), and calculating obtains 57 Layer>, then UE1 can by S Earn, ' 'α,=(β earn (, '.,+SINO I 1 obtain more accurate SINR and survey to replace page to calculate(The 26th article of detailed rules and regulations) Measure result;Similar operation can be carried out for the 2nd antenna port.
Similarly, for uplink, if UE sends IMRS by 2 antenna ports, the 3rd, 4 antenna ports are sent can repeat to send the 1st on the corresponding RE of IMRS, the IMRS of 2 antenna ports.Now, if UE1 and UE2 is by heterogeneous networks device service, and UE1 sends IMRS by 2 antenna ports, and UE2 sends IMRS by 4 antenna ports, then the running time-frequency resource for the IMRS that UE1 and UE2 is sent can be as shown in Figure 8 B.
In addition, in embodiments of the present invention, the network equipment can also send control signaling to close the function of " repetition " to UE, i.e., configured by control signaling and whether repeat to send IMRS.For example, when the control signaling is configured as repeating to send IMRS, then the network equipment 1 can use pattern as shown in Figure 8 A to send IMRS;If control signaling is configured as not repeating to send IMRS, the network equipment 1 does not send IMRS on RE (3,5) and RE (3,6), is so avoided that repetition sends IMRS, reaches the benefit of power saving.
Specifically, in embodiments of the present invention, alternatively, as shown in figure 9, this method 100 also includes:
S140, sends control signaling to the user equipment, and the control signaling is used to indicate whether to repeat to send the IMRS;
Wherein, the IMRS that the reception user equipment is sent, including:When the control signaling indicates to repeat to send the IMRS, the IMRS that the user equipment repeats to send on the reserved RE is received.
Alternatively, the control signaling is the peculiar signaling of user equipment, i.e. the control signaling is that the network equipment is individually sent to the user equipment, the signal for being only used for configuring the user equipment sends and/or received, wherein, the peculiar signaling of the user equipment is referred to as " user equipment specific signaling " or " the peculiar signaling of user equipment ", and the embodiment of the present invention is not limited to this.
Therefore, the method of transmission signal according to embodiments of the present invention, by before transmission data-signal, transmit interferometry reference signal, so that the interference being subject to during signal transmission can be estimated exactly, suitable receiver parameters or adjustment scheduling scheme are so can determine that, so as to strengthen the performance of signal transmission, Consumer's Experience is improved.
In embodiments of the present invention, the network equipment or user equipment can keep orthogonal by least two antenna ports transmission IMRS resources used, consequently facilitating IMRS recipient can distinguish these IMRS.For example, for downlink transfer, enabling to UE to distinguish the different IMRS of network equipment transmission;For uplink, the network equipment is enabled to distinguish the different IMRS that UE is sent.However, in the above example, IMRS occupies too many resource, such as one PRB is accounted for Main function with 4 RE, and IMRS is to be used to measurement thousand disturb information, and needs the demand by IMRS measurement channels not strong.
Therefore, in embodiments of the present invention, for downlink transfer, the network equipment can use identical RE to send IMRS and without using orthogonal code.For example, as shown in Figure 10 A, it is assumed that network equipment i sends IMRS by 4 antenna ports, and is all sent using RE (9,5)(No matter 4 value)If, the IMRS that a-th of antenna port of k-th network equipment is sent for ' "), it is the signal sum Z ' of all antenna ports transmissions in RE (9, the 5) signals sent that the kth network equipment is final>.Similarly, UE can estimate the interference that IMRS is subject to when measuring IMRS according to the method for above-described embodiment.
It should be understood that, in order to estimate SINR, then also need to estimate the corresponding channel information of the network equipment of being serviced, the channel information can be measured other RS by UE and be taken come reed, such as the CSI-RS in LTE systems, and the RS is that the network equipment is sent on full PRB periodically, can be with estimating channel information using CSI-RS, so as to obtain more preferable precision of channel estimation, for sake of simplicity, will not be repeated here.
For uplink, for example, as shown in Figure 10 B, the IMRS that UE is sent by all antenna ports can also take identical RE (- individual or multiple RE), one RE (0 of identical is for example taken shown in Figure 10 B, 13), consequently facilitating reduction IMRS expenses.The network equipment can also obtain interference information by measuring the RE, it is possible to obtain channel information by SRS, so as to calculate S Piao.
Specifically, in embodiments of the present invention, alternatively, this sends interferometry reference signal IMRS to the user equipment, including:By at least two antenna ports indicated by the also included antenna port information of the dispatch, identical is reserved and sends the IMRS to the user equipment using non-orthogonal resource on RE in the PRB;Or
The IMRS that the reception user equipment is sent, including:The user equipment is received by least two antenna port, identical reserves the IMRS. sent on RE using non-orthogonal resource in the PRB
Alternatively, the transmission sequence that each antenna port at least two antenna port is used is identical, so that design is more simple, it is easier to realize.
In embodiments of the present invention, alternatively, this sends thousand to the user equipment and disturbs measuring reference signals IMRS, including:
The IMRS generated according at least one of scrambler and root sequence is sent to the user equipment;Or the IMRS of reception user equipment transmission, including:Replace page(The 26th article of detailed rules and regulations) Receive the IMRS generated according at least one of scrambler and root sequence of user equipment transmission.I.e. in embodiments of the present invention, the network equipment or user equipment can generate IMRS according to scrambler, can also generate IMRS according to root sequence, can also generate IMRS according to scrambler and root sequence.
For example, the IMRS that heterogeneous networks equipment or the UE of heterogeneous networks equipment control are sent can also be superimposed scrambler again to orthogonal code, the IMRS that the UE for controlling heterogeneous networks equipment or heterogeneous networks equipment is sent will not be orthogonal, so that the measurement of UE or the network equipment to interference is more accurate.It should be understood that the method for superposition scrambler is well known to those skilled in the art, it will not be repeated here.
It should be understood that, in various embodiments of the present invention, the size of the sequence number of above-mentioned each process is not meant to the priority of execution sequence, and the execution sequence of each process should be determined with its function and internal logic, and any limit is constituted without tackling the implementation process of the embodiment of the present invention.
Therefore, the method of transmission signal according to embodiments of the present invention, by before transmission data-signal, transmit interferometry reference signal, so that the interference being subject to during signal transmission can be estimated exactly, suitable receiver parameters or adjustment scheduling scheme are so can determine that, so as to strengthen the performance of signal transmission, Consumer's Experience is improved;On the other hand, method according to embodiments of the present invention, IMRS is sent using identical RE and without using orthogonal code, and interference information can be estimated by less RE, is reduced and is further reduced overhead, increases system transmission performance.
Above in conjunction with Fig. 1 to Figure 10 B, the method of transmission signal according to embodiments of the present invention is described in detail from the angle of the network equipment, below in conjunction with Figure 11 to Figure 15, from the angle description of the user equipment method for transmitting signal according to embodiments of the present invention.
It should be understood that interaction and correlation properties of the UE to the network equipment of the description of UE sides, function etc. are corresponding with the description of network equipment side, in order to which cylinder is clean, it will not be repeated here.
As shown in figure 11, the method 300 of transmission signal according to embodiments of the present invention can be performed by such as UE user equipment, and this method 300 includes:
S310, receives the dispatch that the network equipment is sent, and the dispatch includes the frequency resource information distributed for user equipment, and the frequency resource information is used to indicate Physical Resource Block PRB;
