Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, one embodiment of the present of invention provide a kind of system.This system 10 comprises UE110 and base station 120, and wherein, UE at least comprises the first receiver, when described first receiver is used for needing frequency modulation, in gap (gap), carries out frequency modulation; Base station is used for dispatching UE, but on the carrier wave of the first receiver service, does not dispatch UE in gap.Optionally, UE, also for carrying out measurement sampling in the frequency range after frequency modulation, such as, carries out measurements sampling by frequency range after frequency modulation of first receiver of UE.
Optionally, the information relevant to gap is known in UE and base station, is just equivalent to determine gap, and wherein, the information relevant to gap comprises gap cycle and gap duration, also may comprise side-play amount.
The gap cycle represents how long occur a gap.This gap cycle also may represent how long to occur that one-shot measurement samples, and namely gap occurs that the cycle is once identical with measuring the sampling cycle once.Optionally, the unit in this gap cycle is frame or subframe or millisecond or microsecond.Such as, gap cycle A is in units of frame, and A is every 4 frames of 4 expressions is one-period, also namely: a gap appears in every 4 frames.In addition, the time started in a gap cycle may represent with the numbering X of radio frames, and such as, when A is 4, X is the integral multiple of A, then this radio frames being numbered X is the beginning in a gap cycle.
Gap duration represents that the receiver that can be used for UE carries out the time span of frequency modulation.Optionally, the unit of gap duration is frame or subframe or millisecond or microsecond.Such as, gap duration B is in units of millisecond, and B has 20 milliseconds of receivers that can be used for UE to carry out frequency modulation in 20 expression each gap cycles.
Optionally, the information relevant to gap also comprises: side-play amount, represent the skew of time started (or be called frequency modulation opportunity) relative to the time started in the gap cycle at this gap place of gap, i.e. the time difference between the time started in the time started of gap and the gap cycle at this gap place.Optionally, the unit of side-play amount is frame or subframe or millisecond or microsecond.Such as, when the side-play amount in the information relevant to gap is 0, the time started of gap is identical with the time started in gap cycle, supposes that gap cycle A be 20, side-play amount C is 0, then 20 milliseconds of starting are gap each gap cycle.And for example, the information relevant to gap does not comprise offset field in the information of being correlated with gap that this content of side-play amount or UE receive for empty, can be considered that side-play amount is defaulted as 0.Suppose that side-play amount C is 10, unit is millisecond, then each gap cycle starts rear wait 10 milliseconds, and gap starts.Different side-play amount values can make the gap dispersion as far as possible of different receivers, thus avoids each receiver of UE to perform frequency modulation simultaneously and affect UE reception data.
Optionally, the information relevant to gap also comprises measures sampling duration, represents and can be used for the time span that UE carries out measuring sampling.If the information relevant to gap does not comprise measure sampling duration, or the measurement sampling duration field in the information relevant to gap is empty, can be considered: measure that sampling duration is defaulted as in the gap cycle, gap duration terminate after period, or, if certain time before gap duration terminates can both be determined in UE and base station, first receiver completes frequency modulation, then measure that sampling duration can be defaulted as in the gap cycle, the first receiver completes the period after frequency modulation.
In the present embodiment, UE may, when knowing the frequency range needing to measure, determine to perform measurement by the first receiver, and demand and needs frequency modulation that the first receiver performs measure because work at present frequency range does not meet.Then, the first receiver adjusts the center frequency point of operation of receiver and/or carries out band spreading in gap, makes the frequency range after frequency modulation contain the frequency range of needs measurement, can carry out different-frequency measure sampling and data receiver in the frequency range of the first receiver after frequency modulation simultaneously.Such as, suppose the first receiver to be band limits be the CC1 service of 700MHz-720MHz, with the CC2 service that band limits is 800MHz-820MHz, this first receiver current is only this two CC services, and therefore the working frequency range of this first receiver is 700MHz-820MHz.Herein, other receivers of UE frequency modulation be regarded as the first receiver that how to work does not affect, and repeats no more.Suppose that UE needs the target frequency bands carrying out measuring to be 900MHz-920MHz, then UE can in gap, by the first receiver frequency modulation to 700MHz-920MHz, and in measurement sampling duration, at working frequency range be 900MHz-920MHz the first receiver on carry out different-frequency measure, this different-frequency measure can not affect UE and receive data on CC1 and CC2.
Optionally, the first receiver carries out frequency modulation after measurement sampling.For distinguishing twice frequency modulation in the present embodiment, the frequency modulation that the first receiver carried out before measuring sampling is called first time frequency modulation, the frequency modulation after measurement sampling is called second time frequency modulation.Above-mentioned first time, frequency modulation can make the working frequency range of the first receiver broaden, to support that the first receiver carries out measurement sampling and data receiver simultaneously, second time frequency modulation can make the working frequency range of the first receiver narrow, namely the working frequency range of the first receiver after second time frequency modulation is covered by the working frequency range before second time frequency modulation, to save the electricity that the first operation of receiver consumes.Further, the first receiver can carry out frequency modulation in the second gap after measurement sampling.In the gap of second time frequency modulation, this UE is not dispatched in base station on the carrier wave of the first receiver service, thus avoids UE to carry out frequency modulation and base station clashes between the scheduling of UE.Such as, at the end of measuring sampling duration, or when the first receiver completes measurement sampling, the gap duration of second time frequency modulation starts, and the gap duration of this second time frequency modulation is identical with first time gap duration,
If UE saves the working frequency range of the first receiver before first time frequency modulation, or the configuration relevant to this working frequency range, then the first receiver can in second time frequency modulation, working frequency range is adjusted to the working frequency range before first time frequency modulation, or the configuration that application is relevant with the working frequency range before for the first time frequency modulation.Such as, working frequency range for the first time before frequency modulation is 700MHz-820MHz, working frequency range for the first time after frequency modulation is 700MHz-920MHz (being UE to carry out measuring working frequency range when sampling), and the working frequency range after second time frequency modulation is 700MHz-820MHz.
In the present embodiment, the gap duration of frequency modulation and the gap duration of second time frequency modulation also can be different for the first time, that is: relevant to gap information also comprises the 2nd gap duration, represent after measurement sampling duration terminates or the first receiver completes measurement sampling, can be used for carrying out the time span of frequency modulation, in this duration, UE is not dispatched in base station on the carrier wave of the first receiver service.
The present embodiment can avoid UE carry out frequency modulation and base station UE is dispatched between conflict, the waste of interface-free resources can be avoided, increase the scheduling performance of interface-free resources, and reduce the number of times of data re-transmission, increase the reliability of transfer of data.
Value relation between the information relevant to gap as shown in Figure 2, suppose within a gap cycle, UE (first receiver of such as UE) is at least allowed to carry out primary frequency modulation and carry out one-shot measurement sampling after this frequency modulation, B ' in figure represents the gap duration of the second time frequency modulation that may exist in this gap cycle, E represents the remaining time that may exist in this gap cycle, can be used for the work that UE carries out frequency modulation and measures beyond sampling.Then in figure, every variable meets: C+B+D+B '+E≤A.Wherein, C, B ' and the value of E may be all 0 (or claim do not exist), the value of B and D is all greater than 0.
In the embodiment of the present invention, UE can know the information relevant to gap by multiple method with base station, such as, receive from Correspondent Node or self calculate to generate or self storage.No matter be UE or base station, a kind of method can be performed or more than a kind of method to know the information relevant to gap of needs.As long as the information relevant with gap that UE is known with base station is identical, the gap determined is exactly identical, conflict UE just can being avoided to carry out frequency modulation and base station dispatch UE.Comprise gap cycle and gap duration for the information relevant to gap, UE may save the gap cycle, and receives gap duration from base station.And for example, base station receives gap duration from UE, generates the gap cycle by calculating.If base station or UE are known for many times and the content of in gap relevant information, can be as the criterion with the up-to-date information content known.Such as UE saves side-play amount, and have received again the side-play amount that base station sends, then UE is as the criterion with the side-play amount received, and UE can also substitute the side-play amount of preservation by the side-play amount received.
As best shown in figures 3 a and 3b, in an alternative embodiment of the invention, the information relevant to gap can be sent to Correspondent Node by base station or UE, wherein, the information relevant to gap may meet any one situation following: (1) comprises the gap cycle, (2) gap duration is comprised, (3) side-play amount is comprised, (4) gap cycle and gap duration is comprised, (5) gap cycle and side-play amount is comprised, (6) comprise gap duration and side-play amount, or (7) comprise gap cycle, gap duration and side-play amount.Measurement sampling duration can also be sent to Correspondent Node by base station or UE.Because base station or UE just can specify gap according to the information relevant to gap, namely when first receiver of UE is allowed to carry out frequency modulation and when base station does not dispatch UE on the carrier wave of the first receiver service.In the present embodiment, the Correspondent Node of UE is base station, and the Correspondent Node of base station is UE.Below the transmission information relevant to gap is illustrated to Correspondent Node.
Such as, the information relevant to gap can be carried at and send to the RRC of UE to connect in reconfiguration message (S311 as in Fig. 3 a) or other message by base station, optionally, the reserved field that relevant to gap information takies above-mentioned message or the field expanded.It should be noted that, if the information relevant to gap comprises side-play amount, then base station send, the side-play amount of the different receivers of corresponding same UE can be different, affect this UE receive data to avoid each receiver of this UE to perform frequency modulation in the identical time.Side-play amount that base station sends, corresponding different UEs can be different, to avoid multiple UE at identical time frequency modulation, thus improve utilization rate of air interface resource.
And for example, the information relevant to gap can be carried at and send to the RRC of base station connection to reshuffle in message (S321 as in Fig. 3 b) or other message by UE.Optionally, the reserved field that relevant to gap information takies above-mentioned message or the field expanded.And for example, the information relevant to gap, when start or initial access network, is carried at and sends in the UE access capability information of base station by UE.
This embodiment can combine with other embodiments of the invention, and such as, base station only sends the gap cycle to UE, and the gap duration self preserved or generate or receive UE and send may be applied in base station; And UE may apply the gap duration that self preserves or generates.
In the present embodiment, the information relevant to gap can be sent to Correspondent Node by base station or UE, knows information accurately to make Correspondent Node.The present embodiment is also applicable to the scene that the information relevant to gap changes, thus ensures that up-to-date accurate information arrives Correspondent Node, is conducive to base station and UE application gap promptly and accurately, improves the scheduling performance of interface-free resources, and the reliability of transfer of data.
As shown in Figure 4, in an alternative embodiment of the invention, base station or UE can generate the information relevant to gap, wherein, the information relevant to gap may meet any one situation following: (1) comprises the gap cycle, (2) gap duration is comprised, (3) side-play amount is comprised, (4) gap cycle and gap duration is comprised, (5) gap cycle and side-play amount is comprised, (6) comprise gap duration and side-play amount, or (7) comprise gap cycle, gap duration and side-play amount.Base station or UE can also generate and measure sampling duration.In the gap indicated by the information relevant to gap, first receiver of UE is allowed to carry out frequency modulation, and base station is not allowed to dispatch UE on the carrier wave of the first receiver service.Illustrate how to generate the information relevant to gap for UE below, the parameter adopted due to UE is known for base station, and therefore, base station also can adopt identical method to generate the information relevant to gap, hereinafter repeats no more.
Such as, the gap cycle that UE generates can to carry out measuring cycle sample identical with UE (as the first receiver), or carry out the integral multiple in the cycle that measurement samples for UE (as the first receiver).
And for example, the time that UE performs needed for primary frequency modulation according to receiver determines gap duration.The gap duration corresponding with the first receiver that UE generates can perform for being more than or equal to the first receiver arbitrary value that frequency modulation at least one times operates required time.General, gap duration is not more than the gap cycle and UE (as the first receiver) performs the difference that one-shot measurement samples required time.
And for example, UE is according to information determination side-play amounts such as the receiver number of this UE, the marks of this UE, wherein, the mark of UE may be international mobile subscriber identity (International Mobile SubscriberIdentity, or Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (Cell Radio Network TemporaryIdentifier/Identity, C-RNTI) IMSI).Such as, the IMSI mod of the time started X=UE of gap (gap cycle/2), or, the C-RNTI mod of the time started X=UE of gap (gap cycle/2), thus make the gap of this UE be positioned at the first half section time in a gap cycle.Side-play amount=X+ ((gap cycle-X)/receiver number) the * receiver sequence number that each receiver of UE is corresponding, thus the gap making each receiver of UE corresponding disperses.
And for example, UE determined to measure sampling duration according to the receiver time performed needed for one-shot measurement sampling.The measurement corresponding with the first receiver that UE generates samples duration and can perform for being more than or equal to the first receiver the arbitrary value measuring sampling operation required time at least one times.General, measure sampling duration and be not more than the difference that gap cycle and UE perform a gap duration required time.
Optionally, base station or UE, after generating the information relevant to gap (S401), preserve or apply the information (S402) generated, and/or all or part of information generated is sent to Correspondent Node (S403).In the present embodiment, the Correspondent Node of UE is base station, and the Correspondent Node of base station is UE.Such as, base station and UE adopt the generating mode of acquiescence to generate the information relevant to gap, or the information of an Information And Communication opposite end generation of preserving in base station or UE is identical, then the information that base station or UE will not generate sends to Correspondent Node.In addition, if base station and UE save multiple generating mode, then base station or UE may need to adopt which kind of generating mode to Correspondent Node instruction, and such as UE sends the numbering of generating mode or other are indicated to base station, adopt the mode identical with UE to generate identical information to make base station.
It should be noted that, base station or UE directly apply the special case that the information relevant to gap of having preserved can be considered as generating the information of being correlated with gap.Such as, base station and UE preserve identical list, list comprises receiver information (as receiver mark) and with the gap relevant information corresponding to this receiver, base station and UE are identical to the information relevant with gap according to identical receiver information inquiry, and base station or UE extract the information of self preservation and carry out application and be equivalent to generate this information.
In the present embodiment, base station and/or UE can generate the information relevant to gap, and make the information of generation identical because adopting identical parameter, thus UE is when needs frequency modulation, in gap, carry out frequency modulation, and when base station is dispatched UE, in gap, UE can not be dispatched on the carrier wave of the first receiver service, thus improve the scheduling performance of interface-free resources, and the reliability of transfer of data.
An alternative embodiment of the invention also provides UE to determine the method for the receiver corresponding to the information relevant with gap received.
Optionally, UE can whether transmission and reception machine information determines the receiver corresponding to the information relevant with gap received by base station.Such as, base station sends to the message of carrying the information relevant to gap of UE also to carry receiver information (mark as the first receiver), know that to make UE the information relevant to gap in this message is corresponding with first receiver of UE, information that namely should be relevant to gap is effective to the first receiver.If the message of carrying the information relevant to gap does not carry receiver information, then represent that this information relevant to gap can be corresponding with all receivers of this UE, all receivers of information to this UE that namely should be relevant to gap are effective.
Optionally, the relevant information of different-frequency measure that UE can be sent by base station determines the receiver corresponding to the information relevant with gap received.Such as, base station sends the target frequency bands of different-frequency measure to UE, in the receiver of UE, first receiver can cover the target frequency bands of different-frequency measure by frequency modulation, then relevant to gap information is effective to this first receiver, because the working frequency range of the receiver of UE is known for base station, therefore, in this case, the effect of the effective range of the information that the corresponding relation that the target frequency bands of the different-frequency measure of base station transmission serves the instruction information relevant to gap and receiver is correlated with gap in other words.
Further, UE can by receiver information and the corresponding preservation of the information relevant to gap.This receiver, when needs frequency modulation is to carry out different-frequency measure, carries out frequency modulation according in the gap that the information relevant to gap is determined, and carries out measurement sampling in frequency range after frequency modulation.
