Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment 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.

Should understand, technical scheme of the present invention can be applied to various communication systems, for example: global system for mobile telecommunications (GSM, Global System of Mobile communication) system, code division multiple access (CDMA, Code Division Multiple Access) system, Wideband Code Division Multiple Access (WCDMA) (WCDMA, Wideband Code Division Multiple Access) system, GPRS (GPRS, General Packet Radio Service), Long Term Evolution (LTE, Long Term Evolution) system, advanced Long Term Evolution (LTE-A, Long term evolution-Advanced) system, universal mobile telecommunications system (UMTS, Universal Mobile Telecommunication System) etc., the embodiment of the invention does not limit, but for convenience of description, the embodiment of the invention will describe as an example of the LTE network example.

The embodiment of the invention can be used for the wireless network of different standards.Radio Access Network can comprise different network elements in different systems.For example, LTE (Long Term Evolution, Long Term Evolution) and LTE-A (Long term evolution-Advanced, advanced Long Term Evolution) network element of Radio Access Network comprises eNB (eNodeB in, evolved base station), WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)) network element of Radio Access Network comprises RNC (Radio Network Controller in, radio network controller) and NodeB, similarly, WiMax (Worldwide Interoperability for Microwave Access, worldwide interoperability for microwave access) etc. other wireless network also can use and the similar scheme of the embodiment of the invention, just the correlation module in the base station system may be different, the embodiment of the invention does not limit, but for convenience of description, following embodiment will describe as an example of network equipment example.

Will also be understood that, in embodiments of the present invention, subscriber equipment (UE, User Equipment) includes but not limited to travelling carriage (MS, Mobile Station), portable terminal (Mobile Terminal), mobile phone (Mobile Telephone), mobile phone (handset) and portable equipment (portable equipment) etc., this subscriber equipment can be through wireless access network (RAN, Radio Access Network) communicates with one or more core net, for example, subscriber equipment can be mobile phone (or being called " honeycomb " phone), have the computer of radio communication function etc., subscriber equipment can also be portable, pocket, hand-hold type, built-in computer or vehicle-mounted mobile device.

Can be applied to the CA technology according to embodiments of the invention.In the CA technology, UE can send upward signal at a plurality of carrier waves, and the sending and receiving of the upward signal of each carrier wave is relatively independent.In the situation of these upward signals corresponding to different Timing Advances that UE sends, can cause the upward signal of a plurality of carrier waves that UE sends mutually overlapping, for example, Timing Advance corresponding to signal that UE sends carrier wave 1 is TA1, Timing Advance corresponding to signal that sends carrier wave 2 is TA2, if TA1 ≠ TA2 then the overlapping of signal may occur.The overlapping PAPR of upward signal that may cause of signal appearance that sends at different carrier is higher.In addition, for the receiver of distance network equipment UE far away, it is usually larger at the power that each carrier wave sends upward signal, at this moment, even UE has used maximum transmit power, the upward signal of a plurality of carrier waves in the overlapping region can both be sent out simultaneously with enough power.

Can also be applied to the CoMP transmission technology according to embodiments of the invention, in the CoMP transmission technology, between a plurality of network equipments (being also referred to as node), introduce cooperation, and between network equipment, (for example share information, channel condition information, schedule information and data message etc.), to eliminate presence of intercell interference.UE can use different Timing Advances to send upward signal to different nodes on same carrier wave.For example, UE sends first kind upward signal to node 1, sends the Equations of The Second Kind upward signal to node 2.Because UE is different to the path that these nodes send the upward signal process, so time delay is also just different, thereby needs to use different Timing Advances, and like this, also may there be the overlapping problem of upward signal in the CoMP technology.

Be not limited to above-mentioned two kinds of application scenarioss according to embodiments of the invention, can also be applied to according to embodiments of the invention in the various scenes of UE transmission multiclass upward signal.

Fig. 1 is the indicative flowchart that the method for signal transmission according to an embodiment of the invention is shown.The method of Fig. 1 is carried out by subscriber equipment.The method of Fig. 1 comprises following content.

110, use at least two Timing Advances to send in the situation of multiclass upward signal to network equipment at user equipment (UE), this UE sends the overlapping information of at least two class upward signals in the above-mentioned multiclass upward signal to this network equipment.

For example, above-mentioned multiclass upward signal can refer to the upward signal that UE sends at the different carrier of carrier aggregation.Be not limited to this according to embodiments of the invention, for example, above-mentioned multiclass upward signal can also refer to the upward signal that UE sends to the different nodes of cooperative multipoint transmission on same carrier wave.

Whether above-mentioned overlapping information is used to indicate above-mentioned at least two class upward signals and exists in time overlappingly, and for example, it is overlapping that the signal of the signal of n TTI of a class upward signal and n+1 TTI of another kind of upward signal occurs.For example, using at least two Timing Advances to send in the situation of inhomogeneous upward signal, UE can report to network equipment the overlapping information of these upward signals.The below describes as an example of two upward signals of UE transmission example.If UE uses very first time lead to send the first upward signal, send the second upward signal with the second Timing Advance, then UE sends the overlapping information of the first upward signal and the second upward signal to network equipment.Network equipment is after receiving overlapping information, can judge whether these upward signals that UE sends can occur overlapping according to this overlapping information, if can occur overlapping, just can avoid the overlapping of this two classes upward signal by the mode of scheduling, in other words, network equipment obtains after the overlapping information, just can know: if after carrier wave 2 transmitted signals, dispatch immediately UE in carrier wave 1 transmitted signal at scheduling UE, then the overlapping of upward signal can occur, if perhaps dispatch immediately UE to node 1 transmitted signal after node 2 transmitted signals at scheduling UE, it is overlapping then can upward signal to occur.Like this, network equipment just can be avoided such scheduling, thereby avoids occuring the overlapping of upward signal.In addition, UE can also select to abandon one of overlapping multiclass upward signal may occur, and network equipment can not receive the upward signal that is abandoned by UE.

Above-mentioned overlapping information can adopt special signaling to send, and also can be carried in the existing signaling, and for example, the overlapping information in that two upward signals are placed in the fixed position of this signaling is not construed as limiting this according to embodiments of the invention.

Be not limited to above-mentioned two class upward signals according to embodiments of the invention, for example, above-mentioned overlapping information can comprise the overlapping information of the per two class upward signals in the above-mentioned at least two class upward signals, perhaps above-mentioned overlapping information can comprise reference upward signal in the above-mentioned at least two class upward signals and the overlapping information of other class upward signal, does not repeat them here.

For example, network equipment 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.

Can be sent by UE the overlapping information of multiclass upward signal to network equipment according to embodiments of the invention, network equipment whether exist overlapping so that can be known the upward signal of multiclass, in order to process accordingly, thereby can solve the high problem of peak-to-average power ratio of upward signal.

According to embodiments of the invention, this overlapping information comprises Timing Advance poor of two class upward signals in the above-mentioned at least two class upward signals.

For example, above-mentioned overlapping information can be poor (for example, the Timing Advance of the Timing Advance of the difference of the Timing Advance of the per two class upward signals in the multiclass upward signal or fixing reference upward signal and other class upward signal is poor) of the Timing Advance corresponding with above-mentioned two class upward signals.UE can measure Timing Advance poor of above-mentioned two class upward signals, and the difference of above-mentioned Timing Advance is reported to network equipment.

Fig. 2 is the overlapping schematic diagrames of two class upward signals.Referring to Fig. 2, for example, UE can to network equipment report UE sends upward signals at carrier wave 1 and carrier wave 2 Timing Advance poor (for example, TA2-TA1), like this, network equipment just can know that UE sends the overlapping situation of these multiclass upward signals, thereby can avoid this type of overlapping by the mode of for example scheduling.Will also be understood that, TA among Fig. 2 is relative value of expression, what for example TA1 represented is t1 and the interval of t2 between the moment, what TA2 represented is t3 and the interval of t4 between the moment, namely for receiving same Transmission Time Interval (Transmission Time Interval, TTI) downstream signal, the lead of transmitted signal.In addition, poor (for example TA2-TA1) of Timing Advance, it also can be the difference of the time started of the UE above-mentioned multiclass upward signal that sends same TTI (perhaps prosign), be t1+t_TTI-t3, wherein t_TTI represents the length of a TTI, and namely the difference of this Timing Advance is the poor of transmission time for same TTI.For example, if the Timing Advance of the signal of n TTI of the first kind upward signal in the above-mentioned two class upward signals is different from the Timing Advance of the signal of n TTI of Equations of The Second Kind upward signal, then the signal of n+1 TTI of the signal of n TTI of first kind upward signal and Equations of The Second Kind upward signal occurs overlapping.

In 110, surpass in the situation of the first default thresholding in the difference of the Timing Advance of above-mentioned two class upward signals, this UE sends this overlapping information to this network equipment.

For example, when the difference of the Timing Advance corresponding with above-mentioned two class upward signals surpasses a certain default thresholding, UE reports that just above-mentioned overlapping information to network equipment, can reduce the amount that UE reports overlapping information like this, reports above-mentioned overlapping information required expense thereby reduce UE.

Alternatively, as another embodiment, this overlapping information comprises the overlapping state between the two class upward signals in the above-mentioned at least two class upward signals, this overlapping state comprises the first overlapping state and the second overlapping state, the first overlapping state indicates above-mentioned overlapping degree to be positioned at the first default scope, and the second overlapping state indicates above-mentioned overlapping degree to be positioned at the second default scope.

For example, above-mentioned overlapping information can be between the above-mentioned two class upward signals overlapping state (for example, overlapping state between any two or with reference to the overlapping state between upward signal and other class upward signal), be the overlapping degree of above-mentioned two class upward signals, above-mentioned overlapping degree can be weighed with the difference between the Timing Advance of multiclass upward signal.UE determines the overlapping state between the multiclass upward signal, and reports that overlapping state is to network equipment.For example, the first overlapping state can be overlapping for having, and the second overlapping state can be for without overlapping, perhaps, the first overlapping state can be fully overlapping (Full Overlap), and the second overlapping state can overlapping for part (Partial Overlap).

For example, comprise in the overlapping or fully overlapping situation of part at all overlapping states, if overlapping between the multiclass upward signal surpasses a certain thresholding, then UE can report to network equipment and be in the overlapping state of part between these upward signals, otherwise reports complete overlapping state.

Usually, the design of wireless communication system can allow a certain amount of overlapping, if overlapping between the signal is lower than a certain thresholding, then usually can stand, and is namely little on the impact of systematic function.If overlapping this thresholding that is higher than just needs network equipment to avoid the generation of this situation.Fig. 3 is the overlapping schematic diagrames of two class upward signals.Referring to Fig. 3, UE sends two class upward signals and can exist a certain amount of overlapping.Be lower than a certain thresholding T0 if this is overlapping, then can stand, network equipment need not to do any adjustment.If this is overlapping greater than T0, then network equipment just avoids this type of situation to occur by scheduling, for example, can dispatch this two classes upward signal by at least one TTI of interval.Particularly, the i class upward signal mentioned of the present invention and the overlapping state of j class upward signal represent by formula (1):

Wherein, TAi represents the Timing Advance of i class upward signal, and TAj represents the Timing Advance of j class upward signal, and mod represents modulo operation.Wherein threshold T 0 sets in advance usually at UE and network equipment, for example, and 20,30 or 40 microseconds.

When the scope of the difference of the Timing Advance of multiclass upward signal is larger, need the scope of overlapping information of UE report just larger, therefore may need UE to report a lot of information just enough, the signaling consumption that this just need to be more.Therefore, can allow UE only get final product to the overlapping state between the network equipment report multiclass upward signal according to embodiments of the invention, for example, whether UE exists overlapping to network equipment report Equations of The Second Kind upward signal with respect to first kind upward signal, if exist, network equipment just can be avoided overlapping between the upward signal to the scheduling of UE by adjusting, and if there is no, then need not to adjust overlapping between the upward signal avoided in the scheduling of UE.

According to embodiments of the invention, this UE is to the number in the complete transmission time interval at interval between the identical above-mentioned two class upward signals of the numbering of this network equipment transmission Transmission Time Interval.

Fig. 4 is the overlapping schematic diagrames of two class upward signals.Need to prove, at synchronization, the TTI numbering that the inhomogeneity upward signal is corresponding may differ larger, referring to Fig. 4, two TTI numberings that UE sends first kind upward signal may be n and n+1, and two TTI numberings of UE transmission Equations of The Second Kind upward signal may be n+5 and n+6, and namely the TTI that is numbered n+6 of the TTI that is numbered n of first kind upward signal and Equations of The Second Kind upward signal occurs overlapping.At this moment, network equipment just can't know that these inhomogeneous signals have occured overlapping at which TTI, for example, if UE is only to the overlapping state of network equipment report section, network equipment may think that the TTI that is numbered n of first kind upward signal and the TTI that is numbered n+1 of Equations of The Second Kind upward signal occur overlapping, yet in fact but be overlapping with the TTI generation that is numbered n+6 of Equations of The Second Kind upward signal, therefore UE also needs to the number of the fully overlapping TTI of network equipment report, in other words, this UE also needs to the number in the complete transmission time interval at interval between the identical above-mentioned two class upward signals of the numbering of this network equipment transmission Transmission Time Interval, for example, in Fig. 4, the number of the complete TTI at interval is 5 between this two classes upward signal of n TTI, then UE reports that there be the fully overlapping of 5 TTI in this two classes upward signal, perhaps is formulated as follows particularly.

TTI_full＝{(TAi-TAj)-[(TAi-TAj)modt_TTI ]}/t_TTI (2)

Wherein, TTI_full represents the number of fully overlapping TTI, and TAi represents the Timing Advance of i class upward signal, and TAj represents the Timing Advance of j class upward signal, and mod represents modulo operation.

According to embodiments of the invention, UE can report by 1 bit the overlapping state of certain two class upward signal.The overlapping state that correspondingly, can represent respectively with a plurality of bits the in twos upward signal in the multiclass upward signal.For example, 0 expression part is overlapping, and 1 expression is fully overlapping, and perhaps 1 expression part is overlapping, and 0 expression is fully overlapping.

In 110, the overlapping state of this UE between above-mentioned two class upward signals becomes in the situation of default overlapping state, sends this overlapping information to this network equipment.

For example, only have when the overlapping state of certain the two class upward signal in the multiclass upward signal becomes a certain particular state, UE just reports to network equipment.For example, if all overlapping states include overlapping and without overlapping two states, then only need overlapping state when the above-mentioned signal of two classes become to have when overlapping, UE just reports to network equipment.Alternatively, when if all overlapping states comprise the overlapping and complete overlapping two states of part, only need overlapping state when two class upward signals become part when overlapping, UE just reports to network equipment, can reduce the amount that UE reports overlapping information like this, report the expense that overlapping information is required thereby reduce UE.

According to embodiments of the invention, one of above-mentioned at least two class upward signals are fixing reference upward signal, should be the upward signals of at first being dispatched by this network equipment in the above-mentioned multiclass upward signal with reference to upward signal wherein; Perhaps, this is the upward signal that has the minimum time lead in the above-mentioned multiclass upward signal with reference to upward signal; Perhaps, this is the upward signal that has the maximum time lead in the above-mentioned multiclass upward signal with reference to upward signal; Perhaps, this is the upward signal that the main member carrier (Primary Component Carrier, PCC) in carrier aggregation sends with reference to upward signal; Perhaps, this is the upward signal that sends to the host node in the cooperative multipoint transmission with reference to upward signal; Perhaps, this is specified by this information with reference to upward signal that receives from this network equipment with reference to upward signal.

For example, can carry overlapping information with reference to upward signal and a class upward signal in the primary importance of the signaling that is used for sending overlapping information, and place this with reference to the overlapping information of upward signal and another kind of upward signal in the second place of this signaling.

For example, when above-mentioned overlapping information during for the difference of the Timing Advance (i.e. a fixing Timing Advance) of fixing reference upward signal and the Timing Advance of other class upward signal, this fixing Timing Advance can be first Timing Advance in all Timing Advances.For example, network equipment begins only to dispatch UE and sends a class upward signal, and such upward signal arranges a Timing Advance (being first Timing Advance), afterwards can according to service needed gradually configuration UE send more multiclass upward signal, correspondingly, for the upward signal of multiclass more more Timing Advance is set.According to embodiments of the invention this fixing Timing Advance is designed to first Timing Advance in all Timing Advances, fairly simple like this.

Alternatively, an above-mentioned fixing Timing Advance is the maximum or minimum Timing Advance of value in all Timing Advances.For example, this fixing Timing Advance is arranged to the Timing Advance of value maximum in all Timing Advances, the upward signal of Timing Advance maximum is corresponding to the upward signal that sends at first, send first this upward signal and can not cause overlapping problem (for example, sending first the signal of carrier wave 2 among Fig. 2 at n TTI); UE reports the difference of Timing Advance and this Timing Advance of other signal again with this time lead as a reference, facilitates like this network equipment and comes these signals of sequential scheduling according to the order from big to small of these differences, thereby avoid overlapping problem.In like manner, use the Timing Advance of value minimum in all Timing Advances can reach effect same equally.For example, the corresponding last signal that sends of the signal of Timing Advance minimum, this upward signal of rear transmission can not cause overlapping problem, UE with this time lead as a reference, report the difference of Timing Advance and this Timing Advance of other signal, facilitate like this network equipment and come these signals of sequential scheduling according to the order from big to small of these differences, thereby avoid overlapping problem.

Alternatively, an above-mentioned fixing Timing Advance is the Timing Advance corresponding with the upward signal that transmits at main member carrier.In the CA technology, UE can send upward signal at a plurality of carrier waves, and these carrier waves are divided into main member carrier and auxiliary member carrier (Secondary Component Carrier, SCC).UE is in access network, usually access is main member carrier, after the access, network equipment is dispatched UE again and is sent upward signal at other auxiliary member carrier, therefore the priority of main member carrier is usually higher, the probability that uses is also higher, its time lead is also relatively accurate, use the Timing Advance corresponding with main member carrier as a reference, just can guarantee the accuracy of all Timing Advances, and when system, only need UE to report that the difference of the Timing Advance that Timing Advance corresponding to all auxiliary member carriers is corresponding with main member carrier gets final product, and has reduced the complexity of system.

Alternatively, an above-mentioned fixing Timing Advance can be the corresponding Timing Advance of signal that sends to host node.In the CoMP technology, UE can be to a plurality of node transmitted signals, and these nodes are divided into host node and auxiliary node.When the corresponding different districts of these nodes difference, host node is corresponding to the main plot, and auxiliary node is corresponding to auxiliary residential quarter.UE is in access network, and access is host node usually, and after the access, network equipment sends upward signal for the UE scheduling to other node again, so the priority of host node is usually higher.Equally, because the channel conditions of host node is usually better, its time lead is usually comparatively accurate, then use the Timing Advance corresponding with host node as a reference, just can guarantee the accuracy of all Timing Advances, and when system, only need UE to report that the difference of the Timing Advance that Timing Advance corresponding to all auxiliary nodes is corresponding with host node gets final product, and has reduced the complexity of system.

Alternatively, UE can receive reference time lead information from network equipment, indicates the information of an above-mentioned fixing Timing Advance.For example, network equipment can send indication information to UE, is used to indicate UE certain Timing Advance (for example, the Timing Advance corresponding with the Equations of The Second Kind upward signal) is set to the reference time lead, like this can be more flexible.This indication information can adopt the form of dedicated signaling, also can be carried in the existing signaling, for example, the flag bit of the sign by in this signaling, carrying upward signal or the fixed position corresponding with this upward signal indicate UE with the Timing Advance of this upward signal as the reference Timing Advance.

Similarly, when the overlapping state that comprises in the above-mentioned overlapping information was the overlapping state of all kinds of upward signals and a fixing class upward signal (namely with reference to upward signal) in the multiclass upward signal, above-mentioned can be first kind upward signal in all class upward signals with reference to upward signal; Perhaps, above-mentioned can be a transmitting time class upward signal the earliest in all upward signals with reference to upward signal; Perhaps, above-mentioned can be a transmitting time class upward signal the latest in all upward signals with reference to upward signal; Perhaps, above-mentioned can be the signal that the main member carrier in carrier aggregation sends with reference to upward signal; Perhaps, above-mentioned can be the signal that sends to the host node of cooperative multipoint transmission technology with reference to upward signal.In addition, can also send information to UE by network equipment, be used to indicate the information of an above-mentioned fixing class upward signal.For example, describe as an example of 3 class upward signals example, this 3 class upward signal is corresponding TA1, TA2, TA3 respectively, in order to obtain this 3 class upward signal overlapping information each other, do not need the poor of Timing Advance that UE reports that per two class upward signals are corresponding, and only need UE take the Timing Advance of for example first kind upward signal as reference, report respectively Timing Advance corresponding to other class upward signal and this difference of fixing a class Timing Advance to get final product, be that UE only need report TA2-TA1 and TA3-TA1 to get final product, can save signaling consumption like this.

Alternatively, as another embodiment, this overlapping information comprises the Timing Advance of above-mentioned at least two class upward signals.

For example, above-mentioned overlapping information can be the Timing Advance information corresponding with above-mentioned at least two class upward signals.UE can measure the Timing Advance information corresponding with the multiclass upward signal, and report to network equipment, be that UE can directly directly report to network equipment with the Timing Advance corresponding with the multiclass upward signal, network side according to these Timing Advance information can know equally exist between these upward signals overlapping.For example, can at least two fixed positions of the signaling that is used for this overlapping information of transmission, place respectively the Timing Advance of at least two class upward signals.

Alternatively, as another embodiment, this UE also is higher than in the situation of the second default thresholding in the overlapping degree of above-mentioned two class upward signals at least, abandons to have one of overlapping above-mentioned at least two class upward signals.

For example, the overlapping degree of two class upward signals is higher than a certain default thresholding can refer to that the difference of the Timing Advance of two class upward signals is higher than this default thresholding, refer to that perhaps two class upward signals are in the overlapping state of part, can also refer to be higher than this default thresholding through the difference of the Timing Advance of two class upward signals behind the UE Self-adjustment.When the overlapping degree of the multiclass upward signal that sends as UE was higher than a certain thresholding, UE abandoned the part signal in the above-mentioned multiclass upward signal.Network equipment is received after the overlapping information of UE transmission judge according to this overlapping information whether UE abandons above-mentioned multiclass upward signal part signal wherein, if abandon, is then only received the signal that is not dropped.

For example, network equipment scheduling UE sends two class upward signals, and UE reports that to network equipment the Timing Advance of this two classes upward signal is respectively TA1 and TA2 before scheduling, if UE finds the overlapping thresholding T0 that is higher than of multiclass upward signal, then UE abandons a wherein class upward signal; And network equipment can judge whether UE abandons part signal wherein according to these Timing Advances equally, abandons part signal wherein if judge UE, then only receives the signal that is not dropped.

For example, UE can report whether this two classes upward signal is in the overlapping state of part to network equipment, if be in the overlapping state of part, and UE discarded part sub-signal then, and network equipment also can be according to the report of UE and is not received this part signal.

For example, UE can report that UE regulates the adjustment amount of the Timing Advance of all kinds of upward signals voluntarily to network equipment, when the overlapping thresholding T0 that is higher than of UE discovery multiclass upward signal, then discarded part sub-signal.Network equipment also can judge whether this two classes upward signal is overlapping according to the information of UE report, if overlapping, does not then receive this part signal.

According to embodiments of the invention, this UE is higher than in the signal power sum that the overlapping degree of above-mentioned two class upward signals is higher than the overlapping region of the second default thresholding and above-mentioned two class upward signals in the situation of maximum transmission power of this UE at least at least, abandons one of above-mentioned at least two class upward signals.

The overlapping degree of the multiclass upward signal that for example, sends as UE is higher than a certain thresholding and when the power sum of overlapping region was higher than the maximum transmission power of UE, UE can abandon the part signal in the above-mentioned multiclass upward signal.Network equipment receives after the overlapping information of UE transmission, the power information of the UE that can safeguard according to this overlapping information and network equipment judges whether UE abandons the part signal in the above-mentioned multiclass upward signal, if abandon, then only receive the signal that is not dropped.Avoiding an overlapping reason is that PAPR may be higher, and in some system, because the design of signal, so that the problem of PAPR and not serious, therefore be dropped for fear of more signal, further limit according to embodiments of the invention, that only has the multiclass upward signal that sends as UE overlappingly is higher than a certain thresholding and when the power sum of overlapping region was higher than the maximum transmission power of UE, UE is the discarded part sub-signal.Because the transmitted power of UE all is that network equipment is controlled, network equipment also can be safeguarded the transmitted power of UE, so network equipment can judge correspondingly also whether UE abandons this part signal.

According to embodiments of the invention, abandoning when having one of overlapping above-mentioned at least two class upward signals, this UE abandons and has the overlapping lower upward signal of above-mentioned at least two class upward signal medium priorities, and the priority of the signal that wherein sends at the main member carrier of carrier aggregation is higher than the signal that other member carrier of this carrier aggregation sends; Perhaps, the priority that sends to the upward signal of the host node in the cooperative multipoint transmission is higher than the upward signal that sends to the auxiliary node in this cooperative multipoint transmission; Perhaps, the priority that has a upward signal of larger Timing Advance be higher than have hour between the priority of upward signal of lead; Perhaps, the priority of control signal is higher than the priority of data-signal; Perhaps, the priority of detection reference signal is lower than the priority of other signal.

For example, UE can judge the part signal that is dropped according to the height of the priority of all kinds of upward signals.The priority of the signal that sends at the main member carrier of carrier aggregation is higher than the signal that other member carrier sends.The priority of signal that sends to the host node of cooperative multipoint transmission is higher than the signal that sends to auxiliary node.The priority of the signal that Timing Advance is larger is higher than the less signal of Timing Advance, and the signal that Timing Advance is larger is at first sent, and then the more late signal that is sent out of Timing Advance just is dropped.For example, in the LTE system, Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH) carrying upstream control signaling, the data-signal of the upper carrying of its important ratio Physical Uplink Shared Channel (Physical Uplink Shared CHannel, PUSCH) is high, therefore, when if control signal and data-signal are overlapping, just abandon data-signal.The priority of detection reference signal (Sounding Reference Signal, SRS) is lower than other signal, for example, in the LTE system, the purposes of SRS is to be convenient to network equipment to obtain up channel conditions, the information of not transmission reality, so its priority is lower.

Alternatively, as another embodiment, this UE is the Timing Advance of the above-mentioned multiclass upward signal of Self-adjustment also, and wherein this overlapping information comprises the adjustment amount of the Timing Advance of at least two class upward signals in the above-mentioned multiclass upward signal of this UE Self-adjustment.

For example, above-mentioned overlapping information is the adjustment amount of UE Timing Advance of all kinds of upward signals of Self-adjustment in the situation of the TA order that does not receive network equipment.Fig. 5 is the overlapping schematic diagrames of two class upward signals.With reference to figure 5, the method of adjustment of the Timing Advance when UE begins access communication system is: UE receives after the downstream signal of network equipment transmission, the zero hour of determining to receive this downstream signal, namely the time lead was 0 as the delivery time (for TTI) that sends upward signal.Network equipment sends downstream signal to UE constantly at t1, because the transmission path between network equipment and the UE, signal is through after the t_d, UE receives the downstream signal that network equipment sends constantly at t2, constantly send upward signal as the transmission first time of UE at t2, UE also will send upward signal (for example, if UE receives the upward signal of n TTI constantly at t2, then constantly sending the upward signal of n+1 TTI at t2+t_TTI) with the moment of t2 for TTI.Like this, network equipment will be received the upward signal that UE sends constantly at t3, and t3-t2 equals t_d equally.Accordingly, network equipment is the moment that can judge UE transmitted signal this moment, namely network equipment according to delivery time t1 and the time of reception t3 just can judge that the moment of UE transmitted signal is (t1+t3)/2.

After the UE access network, network equipment can send TA to UE orders to notify UE to adjust Timing Advance, for example, adjusts Timing Advance by following formula,

N _TA，new＝N _TA，old+(T _A-31)×16 (3)

Wherein, N _{TA, old}Timing Advance before expression is adjusted, N _{TA, new}Timing Advance after expression is adjusted, T _AThe expression network equipment sends the adjusted value that the TA order is carried to UE, and its span is 0～63, and the unit of these values all is sampled point Ts, and this value is fixed when system, for example, in LTE, Ts=1/ (15000*2048) second.Because UE will order corresponding adjustment Timing Advance according to the TA that network equipment sends, therefore, by this process, network equipment can be known the time of UE transmitted signal equally.

Also allow UE to regulate voluntarily upward signal according to embodiments of the invention, so that higher flexibility to be provided.For example, if network equipment is different from the clock cycle of UE, even the receiver that the upward signal that UE sends in certain transmission course can the reaching on the time network equipment, might there are differences again in the transmission next time, therefore, if the time of the downstream signal that permission UE basis is received changes to regulate the Timing Advance of upward signal, so can reduce the requirement to the precision of clock cycle of UE, and UE has had certain independence, just can avoid network equipment always to send the TA order to UE.For example, send in the scene of multiclass upward signal at UE, because the Timing Advance that UE adjusts is for known to the network equipment, therefore, after UE regulated Timing Advance voluntarily, the time of the UE transmitted signal that network side is safeguarded just made a mistake.Therefore, can make UE regulate voluntarily the adjustment amount of the Timing Advance of all kinds of upward signals to the network equipment report according to embodiments of the invention, so that can knowing UE, network equipment sends the time of upward signal, like this, network equipment all carries out same operation to each class upward signal, it is overlapping just can to know whether UE occurs when sending the multiclass upward signal, thereby can avoid overlapping by the mode of scheduling.Be not limited to this according to embodiments of the invention, for example, can also make the Timing Advance of all kinds of upward signals after UE regulates voluntarily to network equipment report according to embodiments of the invention, can send the time of upward signal so that network equipment can be known UE equally.

Alternatively, as another embodiment, this UE is also after this network equipment sends this overlapping information, before sending next overlapping information to this network equipment, the Timing Advance of the above-mentioned multiclass upward signal of Self-adjustment in preset range is not so that this Self-adjustment changes the overlapping state of above-mentioned at least two class upward signals.

Because UE can regulate Timing Advance voluntarily, very possible such situation: the UE that occurs reports the overlapping for fully overlapping of multiclass upward signal at n TTI to network equipment, but at n+1 TTI with regard to the Self-adjustment Timing Advance, it is overlapping that result after adjusting causes the overlapping state of signal to become part, it is overlapping part to have occured during transmitted signal on this TTI, just abandoned part signal, and network equipment is owing to received the information of UE report, think that UE does not abandon, this just causes understanding inconsistent of the behavior of UE and network equipment, thereby causes the mistake of signal to receive.In order to address this problem, just can make UE after network equipment is reported overlapping information, before reporting overlapping information, with the restriction of UE Self-adjustment Timing Advance within the specific limits, thereby avoid this problem next time.Therefore, UE is after network equipment is reported overlapping information, and before reporting overlapping information, UE is the Self-adjustment Timing Advance within the specific limits next time.

The characteristics of above-mentioned preset range are: UE regulates TA in this scope, can not change the overlapping state of multiclass upward signal.For example, if UE reports overlapping information to network equipment, network equipment overlappingly is lower than thresholding according to what this information can be judged multiclass information that UE sends, and then UE regulates voluntarily Timing Advance and can not make overlapping this threshold value that is higher than after report.Perhaps, if UE reports overlapping information for fully overlapping to network equipment, then UE is after report, and to become part overlapping from fully overlapping to regulate voluntarily state that Timing Advance can not make UE.

Alternatively, as another embodiment, this UE is also after this network equipment sends this overlapping information, before time advance (TA) order that receives the network equipment transmission, the Timing Advance of the above-mentioned multiclass upward signal of Self-adjustment in preset range is not so that this Self-adjustment changes the overlapping state of above-mentioned at least two class upward signals.

Because after this network equipment sends this overlapping information, might network equipment can send TA to UE orders to indicate UE to adjust TA, the priority of this order is usually the highest, therefore UE should order to adjust TA according to this, even can change the overlapping state of above-mentioned at least two class upward signals after adjusting.Because this order is from network equipment, even state has changed, network equipment can know that too UE sends the employed TA value of above-mentioned at least two class upward signals, therefore network equipment and UE still can be consistent to the understanding of overlapping state, and network equipment can be avoided because the impact that the change of overlapping state causes uplink by the said method in this specification.

Alternatively, as another embodiment, this UE also receives from this network equipment and is used to indicate the indication information that this UE sends this overlapping information, wherein this indication information is to satisfy pre-conditioned trigger message for transmission cycle information or this indication information of this overlapping information, wherein this UE sends overlapping information to this network equipment, comprising: this UE sends this overlapping information according to this indication information to this network equipment.

For example, UE can establish the reception indication information from network side, comprising the cycle of indicating UE to report overlapping information.UE receives after this indication information, according to this indication information overlapping information of reporting uplink signal periodically.The overlapping information of UE periodic report like this can be more stable.For example, if network equipment is 200ms to the cycle that UE sends overlapping information, then UE receives after this indication information, just this overlapping information of report take 200ms as the cycle.

For example, UE can also receive trigger message from network equipment, and this trigger message can be flag bit, for example, network equipment can send flag bit 1 to UE when satisfying pre-conditioned, otherwise sends flag bit 0, and UE can be to send overlapping information to network equipment at 1 o'clock at this flag bit.This is pre-conditioned for example can be the network equipment downstream signal received power of receiving the UE report less than default thresholding (usually, this condition satisfy illustrate that namely UE is positioned on the border of the residential quarter that network equipment covers).For another example, this trigger message can be the pre-conditioned thresholding (for example, the above-mentioned first default thresholding) that UE sends this overlapping information, so that UE is according to determining whether to send overlapping information to network equipment by default thresholding.

According to embodiments of the invention, this UE uses above-mentioned at least two Timing Advances to send above-mentioned multiclass upward signal to this network equipment on a plurality of carrier waves.

For example, the multiclass upward signal is corresponding to a plurality of carrier waves of carrier aggregation.For example, have two class upward signals, first kind upward signal is corresponding to carrier wave 1, and the Equations of The Second Kind upward signal is corresponding to carrier wave 2.UE can use very first time lead to send first kind upward signal at carrier wave 1, uses the second Timing Advance to send the Equations of The Second Kind upward signal at carrier wave 2.

Alternatively, as another embodiment, this UE uses above-mentioned at least two Timing Advances to send above-mentioned multiclass upward signal to this network equipment on same carrier wave.

For example, the multiclass upward signal is corresponding to a plurality of nodes of cooperative multipoint transmission.For example, have two class upward signals, first kind upward signal is corresponding to node 1, and the Equations of The Second Kind upward signal is corresponding to node 2.UE can use very first time lead to send first kind upward signal to node 1 on identical carrier wave, uses the second Timing Advance to send the Equations of The Second Kind upward signal to node 2.
