Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is carried out clear, complete description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
One embodiment of the invention provides a kind of method that realizes data demodulates, and as shown in Figure 1, the method comprises:
Step 110: network equipment sends identical CS saltus step information to UE, and described CS saltus step information is used to indicate UE and closes group hopping and/or sequence nucleotide sequence, and indication UE generates the employed CS saltus step of RS scheme; Wherein, it should be noted that according to network equipment described in system requirements the present embodiment and can send identical CS saltus step information to a plurality of UE, so that a plurality of UE adopts identical CS saltus step scheme to generate RS, concrete this paper repeats no more.
Need to prove, the network equipment that relates in the present embodiment can be base station (Base Station, BS), access point (Access Point, AP), far-end wireless device (Remote Radio Equipment, RRE), far-end radio port (Remote Radio Head, RRH), far-end radio-cell (Remote Radio Unit, RRU), via node (Relay node) etc., the present embodiment is not done concrete restriction to this.
Wherein, in the present embodiment, described network equipment indicates described UE to close group hopping and/or sequence jump comprises following several mode, but is not limited to this:
A, in described CS saltus step information, comprised and closed the indication of group hopping and/or sequence jump, closed group hopping and/or sequence jump in order to indicate described UE;
B, default described CS saltus step information operate and have binding relationship with described group hopping and/or the sequence jump of closing, and close group hopping and/or sequence jump when described UE receives described CS saltus step information.
Concrete, described network equipment can send CS saltus step information to described UE in the following manner in the present embodiment, but is not limited to this:
1), described network equipment sends described CS saltus step information by schedule information to described UE; Wherein, described schedule information can also be used to indicate TTI (the Transmission Time Interval that closes group hopping and/or sequence jump, Transmission Time Interval) sign, this TTI sign is used to indicate UE and closes group hopping and/or sequence jump in this TTI;
For example, if network equipment is wished the up RS quadrature that UE1 and UE2 send at the 4th TTI, then just on the 0th TTI, send CS saltus step information to UE1 and UE2 respectively by schedule information, adopt distinctive CS saltus step scheme to generate the indication of RS comprising UE, and close simultaneously group hopping and/or sequence jump; Because this CS saltus step information is carried in the schedule information, and schedule information is dynamic, if therefore in the LTE-A system, network equipment sends schedule information at n TTI to UE, then be used to indicate UE and in n+4 TTI, send upward signal to UE, each transmission of UE all needs network equipment to send a schedule information to UE, network equipment just can be according to the operating position of resource like this, the CS saltus step scheme of dynamically indicating UE to use, for example on the 4th TTI in order to make UE1 and UE2 send the up RS of quadrature, therefore just on the 0th TTI, send schedule information to their and indicate them to use identical CS saltus step scheme; And on other TTI, do not need quadrature, just on other the corresponding TTI except the 0th TTI, send schedule information, indicate them to use different CS saltus step schemes or do not send CS saltus step information to them, do not send CS saltus step information in this case at network equipment, UE acquiescence is used the distinctive CS saltus step in residential quarter scheme (network equipment is the relevant parameter of all the distinctive CS saltus step in UE broadcast transmission residential quarter schemes in the residential quarter in advance).It should be noted that, the CS saltus step information that sends to UE of network equipment can be indicated UE to close group hopping and/or sequence jump and be used the distinctive CS saltus step of UE scheme to generate RS in this example, thereby can use the RS that identical CS saltus step scheme generates can quadrature, and when not wishing up RS that UE sends and other UE quadrature at network equipment, can no longer send CS saltus step information to UE, then UE continue to open group hopping and/or sequence jump, can allow like this UE can obtain the benefit of the interference randomization that group hopping and/or sequence jump bring.
Need to prove, the following examples can be widely used the indicating means of TTI sign, and hereinafter similarly, concrete this paper repeats no more.
Need to prove, in the present embodiment, network equipment namely is the distinctive information of UE to UE with the information that the form of clean culture sends, and namely aims at the parameter that this UE arranges; And network equipment namely is the distinctive information in residential quarter to all UE in the residential quarter with the information that the form of broadcasting sends, and namely is the common parameter that arranges for all UE in the residential quarter; Hereinafter similarly, concrete this paper repeats no more.
2), whether network equipment sends the parameter of one group of described CS saltus step scheme with mode of unicast by semi-static signaling to described UE, and utilize dynamic signaling to indicate described UE to generate RS and whether close group hopping and/or sequence jump with the parameter of described CS saltus step scheme; Perhaps, network equipment sends the parameter of many group CS saltus step schemes to described UE by semi-static signaling with mode of unicast, utilize the numbering of the one group CS saltus step scheme of dynamic signaling in the parameter of the described many group CS saltus step schemes of UE transmission, generate RS and close group hopping and/or sequence with the parameter of described one group of CS saltus step scheme in order to trigger described UE;
For example, network equipment can send the distinctive sequence initialization value of this UE to UE by some bits, thereby so that described UE can be known the distinctive sequence initialization value in residential quarter and the distinctive sequence initialization value of this UE simultaneously, then network equipment can dynamically indicate described UE to select one to generate RS from aforementioned two kinds of sequence initialization values by dynamic signaling, and then can dynamically indicate the RS of the UE transmission quadrature of different districts when at utmost saving dynamic signaling.In the present embodiment, the distinctive sequence initialization value in residential quarter can send out of Memory to UE by network equipment to be determined, is perhaps calculated according to residential quarter ID, according to the computational methods that pre-set by UE and knows, does not do concrete restriction at this.
Again for example, network equipment can send the distinctive 3 groups of sequence initialization values of this UE to UE by some bits, thereby so that described UE can be known the distinctive sequence initialization value in residential quarter and the distinctive 3 groups of sequence initialization values of this UE simultaneously, then network equipment can select one to generate RS from all 4 kinds of sequence initialization values by the described UE of the dynamic indication of dynamic signaling, and then can dynamically indicate the RS of the UE transmission quadrature of different districts when at utmost saving dynamic signaling.
In addition, network equipment can by semi-static signaling to the parameter that described UE sends 1 group CS saltus step scheme, can also indicate whether to close group hopping and/or sequence jump for every group of described CS saltus step scheme at least.For example, network equipment can send the distinctive 3 groups of sequence initialization values of this UE to UE by some bits, and indicate whether to close group hopping and/or sequence for every group of described CS saltus step scheme, for example these front two groups of needs of 3 groups are closed, and last group does not need to close group hopping and/or sequence jump; Then network equipment can select one to generate RS from all 4 kinds of sequence initialization values by the described UE of the dynamic indication of dynamic signaling, if selected the 1st group, then UE generates RS with the parameter of the 1st group of corresponding CS saltus step scheme, and closes group hopping and/or sequence jump; If selected the 3rd group, then UE generates RS with the parameter of the 3rd group of corresponding CS saltus step scheme, group hopping and/or sequence jump is not made any extra process.
In addition, in the present embodiment, use identical CS saltus step scheme to generate RS in order to make a plurality of UE, therefore the parameter of the CS saltus step scheme that sends to described UE of described network equipment comprises following severally, but is not limited to this:
1), described network equipment comprises the CS hopping sequences initialization value that described UE generates RS in the CS saltus step information of described UE transmission;
Concrete, in the LTE-A system, UE generates CS hop value CS3 (n_s) corresponding to RS and is generated by a random sequence, namely CS 3 ( n _ s ) = Σ i = 0 7 c ( 8 N symb UL · n _ s + i ) · 2 i ; Wherein, n_s represents time-gap number, comprises a RS symbol in each time slot, and each TTI comprises 2 time slots;
Figure BDA0000144742870000062
Represent the number of symbols in the time slot, c (.) namely represents random sequence, and UE can determine according to the initialization value c_init of sequence this sequence, and then the CS hop value of definite different time-gap; Therefore, when network equipment is that the UE of different districts arranges identical sequence initialization value, just can make them use identical CS saltus step scheme; Therefore, network equipment directly sends CS hopping sequences initialization value to UE, and UE can directly be worth to come initialization to be used to calculate the random sequence of CS hop value according to this, and for example in the LTE-A system, this initialization value is
Figure BDA0000144742870000063
Represent downward rounding operation, Cell_ID represents residential quarter ID, and span is 0～503, f SsThe initialized deviant of expression CS hopping sequences, its span is 0～29.
2), described network equipment comprises the CS hopping sequences initialization deviant that described UE generates RS in the parameter of the CS saltus step scheme of described UE transmission;
Concrete, transmit the required signaling of CS hopping sequences initialization value in order to reduce, also can send the initialized deviant of CS hopping sequences to UE; Because the span of deviant is less, therefore transmitting this deviant can effectively reduce signaling consumption, can transmit all deviants as only needing 5 bits; Simultaneously, when residential quarter ID corresponding to neighbor cell all corresponding identical
Figure BDA0000144742870000064
During value, network equipment is the deviant fss that the UE of different districts arranges identical sequence initialization value,, the CS sequence initialization value value that the UE of different districts is finally calculated is identical, and then guarantees that different UEs uses identical CS saltus step scheme.
In addition, described network equipment can also send different OCC (Orthogonal Cover Code to UE in the present embodiment, the quadrature mask), so that described UE uses described OCC to be loaded on two RS among the same TTI, thereby can guarantee further that described UE sends the orthogonality of RS; Concrete, if being the different UEs of same residential quarter, network equipment distributed the overlapping PRB of part (Physical Resource Block, Physical Resource Block, for example in the LTE-A system, PRB comprises 12 subcarriers on the frequency), as long as described different UEs uses different OCC to be loaded into two RS on the same TTI, use identical CS saltus step scheme and close group hopping and/or sequence jump, the RS that can guarantee its transmission is quadrature, does not namely have each other interference; For example, if being UE1, network equipment distributed PRB1～3, for UE2 distributes PRB1～5, although the signal that these two UE send has all occupied PRB1～3, but only be required to be UE1 and distribute OCC[+1+1], and be that UE2 distributes OCC[+1-1], be these two UE and be assigned with different OCC, can be so that the RS that these two UE send be mutually orthogonal, and then network equipment just can be distinguished the RS that these two UE send when receiving the signal of these two UE transmissions, thereby can obtain respectively comparatively accurate channel information corresponding to these two UE, and respectively their data be carried out demodulation.
Need to prove, what identical CS saltus step scheme represented is: the changing value of the employed CS of different RS in a TTI is identical.For example, comprise 2 RS among the TTI, the changing value of CS namely is the changing value of the CS value of the CS value used of the 2nd RS and the 1st RS use; For example, for identical TTI, if the CS value that UE1 uses at 2 RS be respectively 3 and the CS value used at 2 RS of 9, UE2 be respectively 4 and 10, then the changing value of employed CS all is 6 on 2 RS of these two UE in this TTI, so they have just used identical CS saltus step scheme.
Step 120: described UE receives the CS saltus step information that described network equipment sends, and described CS saltus step information is used to indicate UE and closes group hopping and/or sequence jump, and the employed CS saltus step of indication UE generating reference signal RS scheme; Close group hopping and/or sequence jump according to described CS saltus step information, and be sent to described network equipment after generating RS with the indicated CS saltus step scheme of described CS saltus step information;
Concrete, in the present embodiment, described UE closes group hopping and/or sequence jump in the following manner, but is not limited to this:
1), after described UE receives the CS saltus step information that network equipment sends, the fixed value that the value of group hopping and/or sequence jump is set to preset in corresponding TTI; For example, take group hopping as example:
For group hopping, if UE receives the CS saltus step information from network equipment, just in corresponding TTI, f_gh (n_s)=0 or f_gh (n_s)=A (A is not equal to 0) are set, and utilize formula u (n_s)=(Cell_ID+f_gh (n_s)) mod 30 to obtain the numbering u (f_gh (n_s) namely represents the value of group hopping) of basic sequence group; Because this moment, the u value was identical for all RS, namely the RS of different time-gap uses identical basic sequence group; For sequence jump, if UE receives the CS saltus step information from network equipment, just in corresponding TTI, v (n_s)=0 or v (n_s)=B (B is not equal to 0) are set, wherein the hop value of sequence subgroup in a certain sequence set of v (n_s) expression; Because this moment, the v value was identical for all RS, namely the RS of different time-gap uses identical basic sequence subgroup; Thereby can guarantee that described group hopping and/or sequence jump are closed.
2), after described UE receives the CS saltus step information that network equipment sends, the employed group hopping of arbitrary RS or sequence jump value when the value of the group hopping of all RS and/or sequence jump is set to open group hopping and/or sequence jump in corresponding TTI; For example, still describe as an example of the group jumping example:
When group hopping was unlocked, the group hopping value of using at the 1st time slot was f_gh (1), and the group hopping value of using at the 2nd time slot is f_gh (2); And after described UE receives the CS saltus step information of network equipment transmission, be arranged on the value of all using f_gh (1) or f_gh (2) when sending RS in described two time slots and obtain the sequence jump value of these two time slots, thereby so that the RS of different time-gap uses identical basic sequence group or basic sequence subgroup, and then can guarantee that described group hopping and/or sequence jump are closed.
Step 130: network equipment obtains the RS that UE sends, and estimates the wireless channel decline according to described RS, demodulates data message according to described wireless channel decline estimated value again.
Because the RS that a plurality of UE that described network equipment receives send is mutually orthogonal, does not disturb between the RS that namely different UEs sends, thereby can improve the accuracy that the wireless channel decline is estimated, and then promote the performance of data demodulates; Simultaneously, need to prove, when described network equipment received the RS of different UEs transmission, being defaulted as was that UE closes the RS that sends after group hopping and/or the sequence jump.
Need to prove, UE at first needs to determine basic sequence when generating RS; Wherein, when group hopping or sequence jump were opened, the RS of different time-gap used different basic sequence group or basic sequence subgroup, then used identical basic sequence group or basic sequence subgroup when group hopping or sequence jump are closed; Then UE distributes to the bandwidth of UE again according to network equipment, determines the employed basic sequence of RS of two time slots among the same TTI from this basic sequence group or basic sequence subgroup.And when network equipment is closed group hopping and/or sequence jump to UE transmission signaling indication UE, (here take group hopping as example, sequence jump is similar, the below repeats no more) UE namely can determine that basic sequence group # that the RS of two time slots uses is all as u (for example according to the computational methods that pre-set, u=Cell_ID mod 30, i.e. f_gh (n_s)=0).At present, the UE of different districts uses different basic sequence groups usually; Therefore, adopt the method for the embodiment of the invention, when group hopping or sequence jump were closed, the UE of different districts used identical CS saltus step scheme to generate RS simultaneously, thereby the up RS that described different UEs is sent is mutually orthogonal, noiseless each other.
Can find out, utilize the method for the various embodiments described above, send CS saltus step information by network equipment to UE, so that different UEs is used identical CS saltus step scheme to generate RS and is closed group hopping and/or sequence jump, and then so that the up RS that different UEs sends keeps quadrature each other, improve the data demodulates performance; Simultaneously, also can make different UEs when not needing to send the RS of quadrature, still obtain the benefit that the interference randomization technology is brought, and then the CoMP technology can be applied in the system with improving performance, and the benefit that still keeps the interference randomization technology to bring.
