Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete description, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
One embodiment of the invention provides a kind of method realizing data demodulation, as it is shown in figure 1, the method includes:
Step 110: network equipment sends identical CS saltus step information to UE, described CS saltus step information is used for indicating UE to close group hopping and/or sequence nucleotide sequence, and indicates UE to generate the CS hop scheme scheme that RS is used；Wherein, it is notable that identical CS saltus step information can be sent to multiple UE according to network equipment described in system requirements the present embodiment, so that multiple UE uses identical CS hop scheme scheme to generate RS, repeat no more the most herein.
It should be noted that, the network equipment related in the present embodiment can be base station (BaseStation, BS), access point (AccessPoint, AP), far-end wireless device (RemoteRadioEquipment, RRE), far-end radio port (RemoteRadioHead, RRH), remote radio units (RemoteRadioUnit, RRU), via node (Relaynode) etc., the present embodiment is to this and is not especially limited.
Wherein, in the present embodiment, described network equipment indicates described UE to close group hopping and/or sequence jump includes following several ways, but is not limited thereto:
A, in described CS saltus step information, contain closedown group hopping and/or sequence jump instruction, in order to indicate described UE to close group hopping and/or sequence jump；
B, default described CS saltus step information have binding relationship with described closedown group hopping and/or sequence jump operation, close group hopping and/or sequence jump when described UE receives described CS saltus step information.
Concrete, the most described network equipment can send CS saltus step information to described UE in the following manner, but is not limited thereto:
1), described network equipment sends described CS saltus step information by schedule information to described UE；Wherein, described schedule information may be used to indicate that closedown group hopping and/or the TTI (TransmissionTimeInterval of sequence jump, Transmission Time Interval) mark, this TTI mark is used for indicating UE to close group hopping and/or sequence jump in this TTI；
Such as, if network equipment wishes that the up RS that UE1 and UE2 sends on the 4th TTI is orthogonal, the most just on the 0th TTI, send CS saltus step information to UE1 and UE2 respectively by schedule information, use distinctive CS hop scheme scheme to generate the instruction of RS including UE, and simultaneously close off group hopping and/or sequence jump；Owing to this CS saltus step information is carried in schedule information, and schedule information is dynamic, if therefore in lte-a system, network equipment sends schedule information at the n-th TTI to UE, then it is used for indicating UE to send upward signal to UE in the n-th+4 TTI, the transmission every time of UE is required for network equipment and sends a schedule information to UE, so network equipment just can be according to the service condition of resource, the CS hop scheme scheme that dynamically instruction UE uses, such as in order to make UE1 and UE2 send orthogonal up RS on the 4th TTI, they use identical CS hop scheme scheme the most just to send schedule information instruction to them on the 0th TTI；And it is not required to orthogonal on other TTI, just send schedule information to them, indicate them use different CS hop scheme scheme or do not send CS saltus step information on other the corresponding TTI in addition to the 0th TTI, not sending CS saltus step information in this case at network equipment, UE acquiescence uses community distinctive CS hop scheme scheme (network equipment shifts to an earlier date the parameter that all UE broadcast transmission communities distinctive CS hop scheme scheme is relevant in community).It should be noted that, to the CS saltus step information that UE sends, network equipment can indicate that UE closes group hopping and/or sequence jump and uses UE distinctive CS hop scheme scheme to generate RS in this example, thus can use identical CS hop scheme scheme generate RS orthogonal, and for network equipment be not intended to UE send up RS orthogonal with other UE time, no longer can send CS saltus step information to UE, then UE continues on group hopping and/or sequence jump, UE so can be allowed to obtain group hopping and/or the benefit of interference randomization that sequence jump is brought.
It should be noted that the following examples can be widely used the indicating means of TTI mark, the most similar, repeat no more the most herein.
It should be noted that in the present embodiment, the information that network equipment sends with the form of clean culture to UE is i.e. the distinctive information of UE, i.e. aims at the parameter that this UE is arranged；And the distinctive information in information Ji Shi community that all UE that network equipment is in community send with the form of broadcast, the common parameter that in Ji Shiwei community, all UE are arranged；The most similar, repeat no more the most herein.
2), network equipment sends one group described in the parameter of CS hop scheme scheme by semi-static signaling to described UE with mode of unicast, and utilizes dynamic signaling to indicate whether described UE uses the parameter of described CS hop scheme scheme to generate RS and whether to close group hopping and/or sequence jump；Or, network equipment sends the parameter of organizing CS hop scheme scheme by semi-static signaling to described UE with mode of unicast more, utilize the numbering of the dynamic signaling one group of CS hop scheme scheme in the parameter of the described many group CS hop scheme scheme of UE transmission, use the parameter of described one group of CS hop scheme scheme to generate RS and to close group hopping and/or sequence in order to trigger described UE；
Such as, if network equipment can send this UE distinctive sequence initialization value by kilo byte to UE, so that described UE can know community distinctive sequence initialization value and this UE distinctive sequence initialization value 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 UE of different districts to send orthogonal RS while at utmost saving dynamic signaling.In the present embodiment, community distinctive sequence initialization value can be sent out of Memory by network equipment to UE and determine, or the computational methods calculating pre-seted according to community ID, basis by UE is known, is not especially limited at this.
The most such as, if network equipment can send the distinctive 3 groups of sequence initialization values of this UE by kilo byte to UE, so that described UE can know community distinctive sequence initialization value and the distinctive 3 groups of sequence initialization values of this UE simultaneously, then network equipment can indicate described UE to select one to generate RS from all 4 kinds of sequence initialization values by dynamic signaling dynamically, and then can dynamically indicate the UE of different districts to send orthogonal RS while at utmost saving dynamic signaling.
Additionally, network equipment can send the parameter of at least 1 group CS hop scheme scheme by semi-static signaling to described UE, it is also possible to indicate whether to need to close group hopping and/or sequence jump for often organizing described CS hop scheme scheme.Such as, if network equipment can send the distinctive 3 groups of sequence initialization values of this UE by kilo byte to UE, and indicate whether to need to close group hopping and/or sequence for often organizing described CS hop scheme scheme, such as these front two groups of needs of 3 groups are closed, and last group need not close group hopping and/or sequence jump；Then network equipment can indicate described UE to select one to generate RS from all 4 kinds of sequence initialization values by dynamic signaling dynamically, if have selected the 1st group, then UE uses the parameter of the 1st group of corresponding CS hop scheme scheme to generate RS, and closes group hopping and/or sequence jump；If have selected the 3rd group, then UE uses the parameter of the 3rd group of corresponding CS hop scheme scheme to generate RS, group hopping and/or sequence jump is not made any extra process.
Additionally, in the present embodiment, in order to make multiple UE use identical CS hop scheme scheme to generate RS, the parameter of the CS hop scheme scheme that the most described network equipment sends to described UE comprises following several, but is not limited thereto:
1), described network equipment comprises the CS hopping sequences initialization value of described UE generation RS in the CS saltus step information that described UE sends；
Concrete, in lte-a system, UE generates CS hop value CS3 (n_s) corresponding for RS and is generated, i.e. by a random sequence CS 3 ( n _ s ) = Σ i = 0 7 c ( 8 N symb UL · n _ s + i ) · 2 i ; Wherein, n_s represents that time-gap number, each time slot include a R/S symbol, and each TTI includes 2 time slots；Representing the number of symbols in a time slot, c (.) i.e. represents random sequence, and UE can determine this sequence according to the initialization value c_init of sequence, and then determines the CS hop value of different time-gap；Therefore, identical sequence initialization value is set as the UE that network equipment is different districts, it becomes possible to make them use identical CS hop scheme scheme；Therefore, network equipment directly sends CS hopping sequences initialization value to UE, and UE directly can initialize the random sequence for calculating CS hop value according to this value, such as, in lte-a system, this initialization value isRepresenting downward rounding operation, Cell_ID represents community ID, and span is 0～503, fssRepresenting the initialized deviant of CS hopping sequences, its span is 0～29.
2), the parameter of the CS hop scheme scheme that described network equipment sends to described UE comprises described UE and generates the CS hopping sequences initialization offset value of RS；
Concrete, in order to reduce the signaling transmitted needed for CS hopping sequences initialization value, it is also possible to send the initialized deviant of CS hopping sequences to UE；Owing to the span of deviant is less, therefore transmit this deviant and can effectively reduce signaling consumption, as only needed 5 bits can transmit all of deviant；Meanwhile, the most corresponding identical as the community ID that neighbor cell is correspondingDuring value, network equipment is deviant fss that the UE of different districts arranges identical sequence initialization value, the final calculated CS sequence initialization value value of UE that also can make different districts is identical, and then ensures that different UE uses identical CS hop scheme scheme.
In addition, the most described network equipment can also send different OCC (OrthogonalCoverCode to UE, orthogonal mask), so that described UE uses on two RS that described OCC is loaded in same TTI, such that it is able to be further ensured that described UE sends the orthogonality of RS；Concrete, if the different UE that network equipment is same community are assigned with the PRB (PhysicalResourceBlock that part is overlapping, Physical Resource Block, such as in lte-a system, one PRB includes 12 subcarriers in frequency), as long as two RS that described different UE uses different OCC to be loaded on same TTI, use identical CS hop scheme scheme and close group hopping and/or sequence jump, can ensure that its RS sent is orthogonal, the most there is not interference；Such as, if network equipment is UE1 is assigned with PRB1～3, PRB1～5 is distributed for UE2, although the signal that the two UE sends all occupies PRB1～3, but only it is required to be UE1 distribution OCC [+1+1], and distribute OCC [+1-1] for UE2, it is the two UE and different OCC is assigned, the RS that the two UE can be made to send is mutually orthogonal, and then network equipment receive the two UE send signal time just can distinguish the two UE transmission RS, it is thus possible to obtain the more accurate channel information that the two UE is corresponding respectively, and respectively their data are demodulated.
It should be noted that identical CS hop scheme scheme represents: the changing value of the CS that the different RS in a TTI are used is identical.Such as, the changing value that TTI includes 2 RS, CS is i.e. the changing value of the CS value that uses of the 2nd RS and the CS value of the 1st RS use；Such as, for identical TTI, if the CS value that UE1 uses on 2 RS is 3 and 9 respectively, the CS value that UE2 uses on 2 RS is 4 and 10 respectively, the changing value of the CS then used on the two UE 2 RS in this TTI is all 6, and therefore they just employ identical CS hop scheme scheme.
Step 120: described UE receives the CS saltus step information that described network equipment sends, described CS saltus step information is used for indicating UE to close group hopping and/or sequence jump, and indicates UE to generate the CS hop scheme scheme that reference signal RS is used；Close group hopping and/or sequence jump according to described CS saltus step information, and use the CS hop scheme scheme indicated by described CS saltus step information to send to described network equipment after generating RS；
Concrete, in the present embodiment, described UE closes group hopping and/or sequence jump in the following manner, but is not limited thereto:
1), after described UE receives the CS saltus step information that network equipment sends, the value of group hopping and/or sequence jump is set to by corresponding TTI the fixed value preset；Such as, as a example by group hopping:
For group hopping, if UE receives the CS saltus step information from network equipment, f_gh (n_s)=0 or f_gh (n_s)=A (A is not equal to 0) is just set in corresponding TTI, and utilizes formula u (n_s)=(Cell_ID+f_gh (n_s)) mod30 to obtain the numbering u value of group hopping (f_gh (n_s) i.e. represent) of basic sequence group；Due to now u value for all RS identical, i.e. 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 arranging v (n_s)=0 or v (n_s)=B (B is not equal to 0) in corresponding TTI, wherein v (n_s) represents the hop value of sequence subgroup in a certain sequence set；Due to now v value for all RS identical, i.e. the RS of different time-gap uses identical basic sequence subgroup；Thus can ensure that described group hopping and/or sequence jump are closed.
2), after described UE receives the CS saltus step information that network equipment sends, by the group hopping of all RS and/or the value of the sequence jump group hopping that when being set on group hopping and/or sequence jump, arbitrary RS is used or sequence jump value in corresponding TTI；Such as, still illustrate as a example by group is jumped:
When group hopping is unlocked, the group hopping value used at the 1st time slot is f_gh (1), and the group hopping value used at the 2nd time slot is f_gh (2)；And after described UE receives the CS saltus step information that network equipment sends, all use the value of f_gh (1) or f_gh (2) to obtain the sequence jump value of the two time slot when being arranged in said two time slot transmission RS, so that the RS of different time-gap uses identical basic sequence group or basic sequence subgroup, and then can ensure that described group hopping and/or sequence jump are closed.
Step 130: network equipment obtains the RS that UE sends, estimates wireless channel decline according to described RS, demodulates data message further according to described wireless channel decline estimated value.
The RS that the multiple UE received due to described network equipment send is mutually orthogonal, does not interferes with such that it is able to improve the accuracy that wireless channel decline is estimated, and then promote the performance of data demodulation between the RS that i.e. different UE send；Meanwhile, during it should be noted that described network equipment receives the RS that different UE sends, it is defaulted as the RS being to send after UE closes group hopping and/or sequence jump.
It should be noted that UE is when generating RS, it is necessary first to determine basic sequence；Wherein, when group hopping or sequence jump are opened, the RS of different time-gap uses different basic sequence groups or basic sequence subgroup, when group hopping or sequence jump then use identical basic sequence group or basic sequence subgroup when closing；Then UE distributes to the bandwidth of UE further according to network equipment, determines, from this basic sequence group or basic sequence subgroup, the basic sequence that in same TTI, the RS of two time slots is used.And when network equipment sends signaling instruction UE closedown group hopping and/or sequence jump to UE, (here as a example by group hopping, sequence jump is similar to, repeat no more below) UE i.e. can according to the computational methods pre-seted determine two time slots RS use basic sequence group # be all u (such as, u=Cell_IDmod30, i.e. f_gh (n_s)=0).At present, the UE being typically different community uses different basic sequence groups；Therefore, the method using the embodiment of the present invention, when group hopping or sequence jump are closed, the UE of different districts uses identical CS hop scheme scheme to generate RS simultaneously, thus the up RS that described different UE can be made to send is mutually orthogonal, the most noiseless.
Can be seen that, the method utilizing the various embodiments described above, CS saltus step information is sent to UE by network equipment, different UE is made to use identical CS hop scheme scheme generate RS and close group hopping and/or sequence jump, and then the up RS making different UE send keeps orthogonal each other, improve data demodulation performance；Meanwhile, different UE also can be made when need not send orthogonal RS still to obtain the benefit that interference randomization technology is brought, and then enable CoMP technology to apply in systems with improving performance, and remain in that the benefit that interference randomization technology is brought.
