It will also be understood that, in embodiments of the present invention, user equipment (User Equipment, referred to as " UE ") terminal (Terminal) can be referred to as, mobile station (Mobile Station, referred to as " MS ") or mobile terminal (Mobile Terminal) etc., the user equipment can be through wireless access network (Radio Access Network, referred to as " RAN ") it is communicated with one or more core nets, such as, user equipment can be mobile phone (or being " honeycomb " phone) or computer with mobile terminal etc., such as, User equipment can also be portable, pocket, hand-held, built-in computer or vehicle-mounted mobile device, they exchange voice and/or data with wireless access network.

It should be understood that the TTI switching in the embodiment of the present invention, may include uplink TTI switching.

Fig. 1 is shown can be using the communication system schematic diagram of the switching method of the embodiment of the present invention.As shown in Figure 1, at DC-HSUPA, main carrier cell and secondary carrier cell are the cells of the different frequent points of same base station, and UE can send and receive data from main carrier cell and secondary carrier cell simultaneously.Main carrier and secondary carrier can configure a plurality of types of TTI.For example, usually carrier wave all configures 2ms TTI, but 2ms TTI and 10ms TTI can also be respectively configured in initial configuration.

Optionally, in the communication system of Fig. 1, there may also be with main carrier same carrier wave third cell and with the 4th cell of secondary carrier same carrier wave, the two cells are same base stations, different from base station in Fig. 1.The two cells can receive the upstream data of UE transmission simultaneously, but cannot be to UE dispatching downlink data.Switch in case of TTI, then can notify the associated base stations of the two cells.

It include in the prior art two methods to the TTI switching of main carrier, one is being switched fast for main carrier TTI, and one is switched by RRC (RRC, Radio Resource Control) signal deployment.

Fig. 2 shows the switching flow schematic diagrames of the TTI of main carrier in the prior art.Below in conjunction with Fig. 2, the method for main carrier TTI in the prior art being switched fast is introduced.It should be noted that, if the switching for the TTI of the main carrier is located in multithread scene, then before the TTI to main carrier is switched over, it needs to deactivate the cell of secondary carrier, the cell of secondary carrier cannot carry out data transmission after deactivation, need to reconfigure relevant parameter by RRC information just can be carried out several biographies later, and use cannot be activated simply by high-speed shared control channel command (High Speed Shared Control Channel order, HS-SCCH order).It is to be understood that the switching of the TTI is equivalent in the scene of single carrier after the cell to secondary carrier deactivates.As shown in Fig. 2, the switching flow includes:

S1, RNC (RNC, Radio Network Controller) send RRC reallocation message to UE.

The reallocation message may include: Radio Bearer Reconfiguration (free translation is radio bearer reconfiguration), Radio Bearer Setup (free translation is radio bearer foundation), Physical channel Reconfiguration (free translation is physical channel reconfiguration), Transport Channel Reconfiguration (free translation is transmission channel reconfiguration), activating set updating (free translation is Active set update), the information such as Cell update (free translation is cell update), it can also include Enhanced-DedicatedChannel (E-DCH in reallocation message, Enhanced Ded Icated Channel) TTI relevant configuration information and other relevant informations, in order to which UE according to these information configuration relevant parameters and is used, reallocation message can further include E-DCH TTI preconfigured information, which can store in variable In OTHER_TTI_E-DCH_CONFIGURATION (free translation is other TTI_E-DCH_ reconfiguration), in order to which UE is pre-configured according to the reconfiguration message.

S2, UE report (Filtered UPH Measurements Report) to the filtering user equipment power headroom measurement that base station sends main carrier.

S3, base station send radio link parameter update to RNC and indicate (Radio Link Parameter Update Indication) information, which indicates to include filtering UPH measurement report in information.

S4, RNC is receiving filtering UPH measurement report, and it determines when being switched over to the TTI of main carrier, wireless link reconfigured preparation (Radio Link Reconfiguration Prepare) message is sent to base station, the wireless link reconfigured ready message is used to indicate the corresponding configuration parameter information of target TTI of base station configuration main carrier, base station can prepare to send corresponding switching command to UE according to the wireless link reconfigured preparation message, and the switching command is used to indicate the configuration parameter that the TTI configuration information of main carrier is switched to target TTI by UE.

S5, base station send wireless link reconfigured completion (Radio Link Reconfiguration Ready) information after completing to be pre-configured, to RNC.

S6, RNC send wireless link reconfigured appointment (Radio Link Reconfiguration Commit) information after receiving wireless link reconfigured completion information, to base station.The wireless link reconfigured assignment information is used to indicate the object time of base station TTI switching.

S7, base station send HS-SCCH order (a kind of command format of the switching command in the HS-SCCH order, that is, S4) to UE, which is used to indicate the TTI of UE switching main carrier.

For example, the HS-SCCH order may include that 2ms TTI switches to 10msTTI and 10msTTI and switches to two order of 2ms TTI.

S8, UE switch the TTI of main carrier after receiving HS-SCCH order.

S9, base station send radio link parameter update to RNC and indicate (Radio Link Parameter Update Indication) information, to indicate to complete the TTI switching of main carrier.

Alternatively, being also possible to be to configure to switch by RRC signaling to the TTI switching of main carrier in the prior art.Specifically, UE can also carry out TTI switching by reporting the RRC signalings such as 6a or 6d to trigger RNC, for RNC in the configuration information for the new TTI for carrying main carrier into the reallocation message that base station is sent, the TTI of main carrier is switched to the configuration of new TTI according to the configuration information of the new TTI by base station and UE.The TTI that process switches main carrier is reconfigured by RRC on triggering in RNC, but the program used time is longer, influences the data transmission success and rate of UE, in some instances it may even be possible to will lead to call drop.

As described above, in the prior art under multithread scene (for example, dual carrier scene), TTI switching is not supported to main carrier and secondary carrier simultaneously or do not carried out simultaneously to the method for only existing the TTI switching for single carrier, current communication standard.In multithread scene, the TTI of main carrier can only be switched over, and when switching the TTI of main carrier, need to deactivate the cell of secondary carrier, flexibly the TTI of excessively a carrier wave cannot be switched over, affect the efficiency of communication according to communication requirement.The present invention provides the methods that one kind can switch over the TTI of main carrier and secondary carrier, including switching over simultaneously to the TTI of major-minor carrier wave and to the method that any carrier wave in major-minor carrier wave carries out TTI switching, can be improved communication efficiency.

Fig. 3 shows the schematic diagram of the switching method 100 of the TTI of the embodiment of the present invention, as shown in figure 3, this method 100 can be executed by UE, base station and RNC.

S101, UE send user equipment power headroom (UPH, User Equipment Power Headroom) information to base station, and the UPH information includes the UPH of the secondary carrier of the UPH and/or the UE of the main carrier of the UE；

It should be understood that above-mentioned UPH can be filtering UPH (Filtered UPH), the i.e. UPH Jing Guo filtration treatment.Above-mentioned UPH is also possible to the UPH by other processing, and this is not limited by the present invention.

It optionally, in embodiments of the present invention, in primary send while can include the UPH of the main carrier and UPH of secondary carrier in the UPH information.The UPH information can also respectively include the UPH of main carrier and the UPH of secondary carrier in multiple send.In other words, the UPH of main carrier can be only included in the UPH information that UE is once sent to base station, or only includes the UPH of secondary carrier, can also simultaneously include the UPH of the main carrier and UPH of secondary carrier.

Optionally, when the UE UPH information sent to base station only includes the UPH of main carrier, base station can determine the UPH of secondary carrier, and in the UPH for adding secondary carrier into the UPH information that RNC is sent according to the UPH of main carrier.Alternatively, base station can also send the UPH of main carrier to RNC, the UPH of secondary carrier is determined according to the UPH of main carrier by RNC.

Such as, UPH refers to Dedicated Physical Control Channel (the Dedicated Physical Control Channel on the maximum transmission power and carrier wave of user equipment, DPCCH) the ratio of code power, wherein the DPCCH code power on carrier wave refers to the DPCCH channel code power that user equipment is sent on the carrier wave.Wherein the maximum transmission power of user equipment is known constant.In the deactivated situation of secondary carrier, DPCCH channel is sent between base station and UE not in secondary carrier, but pilot signal transmitted is distinguished in base station on main carrier and secondary carrier, UE can be to the power measurement of base station or the RNC main carrier for reporting UE to receive and the pilot signal of secondary carrier, base station or RNC can be according to the power measurements, really Determine the first power difference of the pilot signal of main carrier and secondary carrier.As an example, base station and RNC can be approximately equal with the power difference of DPCCH by the power difference of the pilot signal of major-minor carrier wave.To which first power difference can be determined as the second power difference of the DPCCH of main carrier and secondary carrier by base station or RNC；Base station or RNC can calculate the UPH of secondary carrier according to the UPH of main carrier and second power difference.

Optionally, base station and RNC can not also determine the UPH of secondary carrier by the UPH of main carrier, and other methods is taken to determine the UPH of secondary carrier.For example, when secondary carrier is in unactivated state, base station or RNC have been pre-configured with the performance number of the initial DPCCH in secondary carrier.Base station or RNC can determine the UPH of the secondary carrier of UE according to the performance number of the DPCCH of the preconfigured secondary carrier and the maximum power transfer value of UE.Alternatively, base station or RNC can also take other methods to determine the UPH of secondary carrier, the embodiment of the present invention is not construed as limiting this.

S102, the base station send the UPH information to radio network controller (RNC)；

S103, in the case where the RNC is determined based on the UPH information and is switched over to the TTI of the target carrier in the main carrier and the secondary carrier, the base station sends switching command to the UE, and the switching command is used to indicate the TTI that the UE switches the target carrier.

It should be understood that above-mentioned target carrier can only include a carrier wave in main carrier and secondary carrier, it can also simultaneously include main carrier and secondary carrier.

Optionally, in the case where RNC is determined based on UPH information and is switched over to the TTI of the target carrier in main carrier and secondary carrier, RNC can to base station send TTI indication message (such as, the TTI indication message can be wireless link reconfigured preparation and/or wireless link reconfigured assignment information in the method for Fig. 2), the TTI indication message is used to indicate configuration parameter and/or the switching time of the to be switched target TTI of the base station target carrier, in order to which base station sends switching command to UE according to the TTI indication message, and the corresponding configuration parameter of the TTI to base station configuration target carrier.

Optionally, which can order for High-Speed Shared Control Channel (HS-SCCH, High Speed Shared Control Channel).

In embodiments of the present invention, the UPH information that UE is sent to base station includes the UPH of the secondary carrier of the UPH and UE of the main carrier of UE, in order to which RNC switches over the TTI of the target carrier in main carrier and secondary carrier according to the determination of UPH information, to realize the TTI switching to main carrier and secondary carrier, communication efficiency is improved.

Optionally, this method further include:

S104, the UE switch the TTI of the target carrier according to the switching command.

It should be understood that in embodiments of the present invention, this method 100 can be used in multicarrier scene, wherein the multicarrier scene may include dual carrier scene.In other words, the secondary carrier in this method 100 can be multiple secondary carriers, or a secondary carrier.

Optionally, as one embodiment, the secondary carrier is in deactivation status, the switching method further include: the base station sends activation-switching command to the UE, activation-the switching command is used to indicate the UE and activates the secondary carrier, and switches the TTI of the secondary carrier.

For example, activation-the switching command can be HS-SCCH order.

For example, as an example, when the secondary carrier of UE is in deactivation status, the UPH of main carrier is only included in the UPH information that UE is reported, base station receives the UPH that can determine secondary carrier after UPH information according to the UPH of main carrier.Alternatively, details are not described herein again as it was noted above, base station can also determine the UPH of secondary carrier using other methods.In the case where base station determines activation secondary carrier, base station can determine whether to switch the TTI of secondary carrier according to the UPH of secondary carrier.Herein switch secondary carrier TTI refer to whether switch after activating secondary carrier secondary carrier before deactivation or initial configuration TTI.If the base station determine that not switching the TTI of secondary carrier after activating secondary carrier, base station can send activation command to UE, to activate secondary carrier, the configuration parameter of the TTI of the secondary carrier after activation can maintain the initial configuration of TTI or the configuration parameter for the TTI before secondary carrier deactivation；If the base station determine that activating secondary carrier and switching the TTI of secondary carrier, base station sends activation-switching command to UE can define the activation-switching command to activate secondary carrier and switch the TTI of secondary carrier between base station and UE.Wherein, base station determines whether to switch the TTI of secondary carrier, can be and is determined whether to switch secondary carrier according to the UPH of secondary carrier.For example, if illustrating uplink covering at this time when the UPH of secondary carrier is greater than or equal to first threshold preferably, the TTI of secondary carrier being switched to 2ms by 10ms；If the UPH of secondary carrier is less than or equal to second threshold, illustrates that uplink covering at this time is poor, the TTI of secondary carrier can be switched into 10ms by 2ms.Alternatively, base station can also determine whether the TTI for switching secondary carrier according to instruction according to the instruction of the TTI for whether switching secondary carrier of RNC.

Optionally, UE can be pre-configured main carrier and the relevant TTI parameter of secondary carrier.The TTI parameter can be obtained from RNC, can also be obtained otherwise, this is not limited by the present invention.For example, UE can receive reconfiguration information from RNC, which is used to indicate the configuration parameter of the main carrier of UE and/or the TTI of secondary carrier, and the configuration parameter of the TTI of main carrier and/or secondary carrier can be stored in advance according to the reconfiguration information in UE.As one embodiment, as shown in figure 4, UE is when being pre-configured, can using it is major-minor independently save by the way of carry out TTI pre-configuration.That is the corresponding TTI parameter of main carrier and secondary carrier is independently saved and is configured.

For example, the format of the TTI of main carrier and secondary carrier can respectively include 2ms TTI and 10ms TTI, and the major-minor mode independently saved may include: under dual carrier scene

(1) main carrier 2ms TTI；

(2) main carrier 10ms TTI；

(3) secondary carrier 2ms TTI；

(4) secondary carrier 10msTTI.

UE can the corresponding configuration parameter of each TTI to main carrier and secondary carrier carry out separate configurations.That is: in reallocation message the TTI parameter configuration used can be respectively configured for main carrier and secondary carrier in RNC, and increases the TTI information of pre-configuration.For example configuration UE uses main carrier configuration 2ms TTI at the beginning, secondary carrier 2ms TTI, it then can also further be pre-configured main carrier 10ms TTI parameter configuration, secondary carrier 10ms TTI parameter configuration, UE stores the TTI information of TTI information and pre-configuration used in connection with, then when main carrier occurring later and/or secondary carrier TTI switches, it does not need reconfiguration and issues corresponding configuration information, but by switching command (such as, HS-SCCH order) directly require UE using new configuration, it reduces configuration flow and accelerates switching time.

Optionally, base station can send corresponding switching command respectively by main carrier and secondary carrier, i.e., base station is sent by main carrier sends the switching command for being directed to the TTI of secondary carrier for the switching command of the TTI of main carrier and base station by secondary carrier.

Alternatively, base station can also send the switching command of the TTI for secondary carrier by main carrier.As one embodiment, when base station sends switching command by main carrier, which may include the first instruction information, which is used to indicate the switching command corresponding to main carrier or secondary carrier.For example, the first instruction information can serve to indicate that the switching command is the order switched over to the TTI of main carrier, alternatively, can be used for indicating that the switching command is the switching command for secondary carrier.For example, 1bit indicating bit can be increased in switching command, when the indicating bit is assigned a value of 1, indicate that the switching command is the switching command for main carrier, when the indicating bit is assigned a value of 0, indicates that the switching command is the switching command for secondary carrier.Or the HS-SCCH order form that 10ms is switched to for secondary carrier 2ms can be increased, and the HS-SCCH order of 2ms is switched to for secondary carrier 10ms.

As one embodiment, as shown in figure 5, UE can also be pre-configured by the way of the preservation of major-minor joint, main carrier and the corresponding TTI configuration parameter of secondary carrier are combined by which, are then saved and are configured in a manner of TTI combination.For example, UE can receive the reconfiguration information of RNC transmission, which can indicate that main carrier and auxiliary load can be stored in advance with above-mentioned combination according to the reconfiguration information in the main carrier of UE and the combination and configuration parameter of the TTI of secondary carrier, UE The configuration parameter of wave.

For example, it may include four kinds of combinations that the form of the TTI information of main carrier and secondary carrier, which can include respectively 2ms TTI and 10ms TTI, under dual carrier scene:

(1) main carrier 2ms TTI+ secondary carrier 2ms TTI；

(2) main carrier 2ms TTI+ secondary carrier 10ms TTI；

(3) main carrier 10ms TTI+ secondary carrier 2ms TTI；

(4) main carrier 10ms TTI+ secondary carrier 10ms TTI.

UE can respectively correspond the pre-configuration that these four combinations carry out relevant TTI parameter.Network can be stored as one group of TTI parameter to UE, UE using wherein a certain collocation form as currently used parameter configuration；While network can also issue the configuration parameter of the TTI of one or more of the other three in combination as preconfigured information, UE stores the preconfigured information, and the TTI occurred for after, which switches, to prepare.It should be noted that, even if the configuration parameter of the TTI of the same format of same carrier wave, can also be different in different combinations in the mode that major-minor joint saves.For example, certain configuration parameters in the main carrier 2ms TTI in combination (1) and combination (2) can be different.

Optionally, as one embodiment, base station may include second indication information to the switching command that UE is sent, which is used to indicate the combination of the target TTI of main carrier and secondary carrier.It should be understood that the combination of target TTI can refer to the combination of the to be switched TTI of main carrier and secondary carrier.

For example, base station can send switching command to UE by main carrier in the mode that major-minor joint saves.The switching command can come into force on two carrier waves of main carrier and secondary carrier.Wherein it is possible to which the various combination mode according to target TTI defines different switching commands.For example, the combination that switching command includes the target TTI after main carrier and secondary carrier switching can be defined.It is all using identical switching command for example, either still switching to main carrier 10ms TTI+ secondary carrier 10ms TTI from main carrier 2ms TTI+ secondary carrier 2ms TTI from main carrier 2ms TTI+ secondary carrier 10ms TTI.So the number that the type number of switching command can be combined with major-minor carrier wave TTI is identical under this kind of definition mode.For example, in the 5 embodiment of figure 5, switching command can use 00,01,10,11 combination for respectively indicating four kinds of TTI.So under this definition mode, it is only necessary to 4 kinds of switching commands.In embodiments of the present invention, the second indication information in switching command indicates to be switched TTI to UE, simplifies the type of switching command by the combination of instruction main carrier and the target TTI of secondary carrier.

It optionally, can be using synchronous reconfiguration process to the configuration flow of the TTI switching between base station and RNC.

Optionally, base station is after UE reception UPH information, when sending the UPH information to RNC, can increase third instruction information in the UPH information, third instruction information is used to indicate the corresponding relationship between the UPH information UPH for including and main carrier and secondary carrier.For example, third instruction information can indicate that the UPH that UPH information includes is the UPH of main carrier, or indicate that UPH that the UPH information includes is the UPH of secondary carrier.For example, can add in UPH information an information unit (IE, Information Element), indicate that the UPH in UPH information belongs to main carrier either secondary carrier by the IE.Alternatively, one IE of addition, is used for transmission the UPH value of secondary carrier.

Optionally, RNC is determining that RNC can send indication message to base station, which, which is used to indicate, switches over the TTI of target carrier when switching over to the TTI of the target carrier in main carrier and secondary carrier.Successively need to carry out the scene of TTI switching for main carrier and secondary carrier.In view of RNC to base station send information there are Iub interface time delays the problems such as, wherein Iub interface is the interface between RNC and NodeB, information is transmitted by the interface between RNC and NodeB, it is possible that RNC determines the TTI for first cutting main carrier, the TTI of switching secondary carrier is determined later, but when sending related news, base station may be arrived first in the reallocation message of the TTI of the secondary carrier of rear starting, and base station may be after the relevant parameter for the TTI for having configured secondary carrier, just receive the reconfiguration message in the main carrier TTI formerly started, base station sends switching command to UE sequentially in time, to cause the fault in TTI handoff procedure.

To solve the above-mentioned problems, optionally, in embodiments of the present invention, in the case where RNC determination successively carries out TTI switching to main carrier and secondary carrier, RNC can determine whether the time interval between the above-mentioned switching of TTI twice is less than predetermined threshold, and when the time interval is less than predetermined threshold, RNC can wait for a period of time, until preceding TTI switching flow terminates and then starts posterior TTI switching flow.

Optionally, in embodiments of the present invention, when RNC is used to indicate to the indication message that base station issues the combination of the to be switched target TTI of main carrier and secondary carrier, TTI switching is successively carried out to main carrier and secondary carrier in RNC determination, and in the case that RNC determines that the time interval between TTI switching twice is less than predetermined threshold, RNC can increase by the 4th instruction information in the indication message of posterior switching flow, and it is invalid that the 4th instruction information is used to indicate preceding switching flow.For example, may include the service identification (Transaction Identification) of preceding switching flow in the 4th instruction information.When base station receives two indication messages of RNC transmission within a short period of time, base station can indicate that information determines that the switching flow of another indication message instruction is invalid according to the 4th in one of indication message, so that it is corresponding subsequent to only carry out effective indication message Process.Such as, when the current TTI combination of UE is main carrier 2ms TTI+ secondary carrier 2ms TTI, the to be switched target TTI combination that the indication message that RNC is formerly issued to base station indicates is main carrier 2ms TTI+ secondary carrier 10ms TTI, RNC is main carrier 10msTTI+ secondary carrier 10msTTI in the to be switched target TTI combination that the rear indication message sent to base station indicates in a relatively short period of time, RNC can add the 4th instruction information in the indication message in rear hair, the switching flow that 4th instruction information is used to indicate the indication message instruction formerly sent out base station is invalid, base station is after receiving two indication messages, it can be according to the 4th instruction information, only carry out the switching of posterior indication message instruction Process executes the switching flow that the TTI of the carrier wave of UE is switched to main carrier 10msTTI+ secondary carrier 10msTTI.
