Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.Obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
As shown in Figure 1, the embodiment of the invention 1 provides a kind of method that sends business datum, comprising:
Step 101: in the Transmission Time Interval of determining, send business datum;
Step 102: the Transmission Time Interval that is used for sending this professional follow-up data in the notification terminal current dispatching cycle.
In the embodiment of the invention, the Transmission Time Interval of business datum can be determined to send in the base station within a dispatching cycle, so that it is more flexible to send business datum, thereby reduces data transmission delay, avoids loss of data.
The below is described in detail by 2 to embodiment 3 pairs of above-described embodiments 1 of the embodiment of the invention take the MBMS business as example.
The present embodiment 2 can comprise the steps:
Step 201:eNB determines dispatching cycle; This step is optional step.
Concrete, eNB can determine dispatching cycle for this MBMS business datum after determining to adopt single cell pattern to send certain MBMS business datum, for example, and according to the automatic configuration schedules of the information cycles such as QoS of UE, or human configuration dispatching cycle according to the actual requirements.Further, eNB can pass through length and the original position notice UE of multiple spot control channel (MCCH, Multipoint Control Channel) with definite dispatching cycle.
Step 202:eNB determines to be used in dispatching cycle the TTI of transmission MBMS data, for example the 2nd TTI and the 6th TTI.
Need to prove, the eNB in this step can be used for the one or more TTI in the dispatching cycle MBMS transmission data, also can be within this dispatching cycle MBMS transmission data not.
Step 203:eNB sends this MBMS business datum in the 2nd TTI, and there is the TTI of the follow-up data that is used for this MBMS business of transmission in notification terminal in current dispatching cycle.
In this step, eNB can send indication information in the 2nd TTI, has the Transmission Time Interval that is used for sending the professional follow-up data of this MBMS in this indication information indication current dispatching cycle.Concrete, this indication information can be carried in the physical down link control channel message that sends to terminal or in the media interviews control head of multicast protocol Data Unit, for example indication information can take extension bits or the extended field of above-mentioned message or media interviews control head.Take n dispatching cycle shown in Figure 2 as example, comprise 8 TTI a dispatching cycle, Extend1 is the indication information that physical downlink control channel message is carried, then eNB sends the MBMS business datum in the 2nd TTI, and the Extend1 that sends in the 2nd TTI is set to 1, is used to indicate also to have the TTI that is used for sending the professional follow-up data of this MBMS in this dispatching cycle.
Step 204:eNB sends the follow-up data of this MBMS business in the 6th TTI, and there is not the TTI for the follow-up data of this MBMS business of transmission in notification terminal in current dispatching cycle.
Concrete, take n dispatching cycle shown in Figure 2 as example, eNB sends the follow-up data of this MBMS business in the 6th TTI, and the Extend1 that sends in the 6th TTI is set to 0, is used to indicate the TTI that does not exist in this dispatching cycle for sending the professional follow-up data of this MBMS.
In the present embodiment, indication information Extend1 can only take 1 bit, takies resource few.
The embodiment of the invention 3 is similar with above-described embodiment 2, and difference is, the present embodiment indicating information is used to indicate the position of the TTI that sends the professional follow-up data of MBMS behind the TTI that determines.
Concrete, the step 201-202 class among the step 301-302 in the present embodiment and the embodiment 2 is similar, suppose that eNB determines transmission MBMS business within n dispatching cycle the 2nd and the 6th TTI, repeats no more.Among the step 303-304 in the present embodiment, eNB sends the MBMS business datum in the 2nd TTI, and the notification terminal TTI that be used for to send the follow-up data of this MBMS business is the 6th TTI in the current dispatching cycle; ENB sends the follow-up data of this MBMS business in the 6th TTI.
The present embodiment indicating information Extend2 can be can direct representation TTI position sequence number value, the scope that its value can represent is relevant with the quantity of TTI in dispatching cycle, for example, comprise 20 TTI dispatching cycle, then the indicating range of indication information comprises 0～19.For example 100 expression sequence numbers are 5, i.e. the 6th TTI, and and for example 000 expression sequence number is 0, i.e. the 1st TTI.Take n dispatching cycle shown in Figure 3 as example, comprise 8 TTI a dispatching cycle, the indication information Extend2 that physical downlink control channel message is carried takies 3 bits, the Extend2 that eNB sends in the 2nd TTI is set to 101, and being used to indicate the TTI that sends the professional follow-up data of this MBMS is the 6th TTI of current dispatching cycle; The Extend2 that eNB also sends in the 6th TTI is set to nul1 or the physical downlink control channel message that sends in this TTI is not carried indication information.
The value of Extend2 and TTI position can consist of the indication tabulation in the present embodiment.For example, Extend2 is 1 in this table, the 4th TTI in the corresponding current dispatching cycle; Extend2 is 2, the 6th TTI in the corresponding current dispatching cycle.Above-mentioned indication tabulation can be stored respectively by eNB and UE, also can provide inquiry by other network entities storages and for eNB and UE; Above-mentioned indication tabulation can comprise TTI positions all in the dispatching cycle and the corresponding relation of Extend2 value, also can only comprise the TTI position that may be used for transmission MBMS business datum of eNB and UE agreement and the corresponding relation of Extend2 value, thereby reduce the bit that indication information takies, avoid the unnecessary wasting of resources.
The value of Extend2 and TTI position can also consist of the location interval tabulation in the present embodiment.For example, Extend2 is 1 in this table, and the correspondence position spacing parameter is 4, and expression sends the TTI of professional follow-up data and the TTI sequence number difference of current TTI is 4, and when supposing that current TTI is the 2nd TTI, the TTI that sends professional follow-up data is the 6th TTI.
Further, the value of Extend2 can comprise that also there is not the situation for the TTI that sends follow-up data in indication in this step, for example Extend2 is nul1 or is the value of certain agreement, does not exist in the corresponding current dispatching cycle for the TTI that sends follow-up data.
In the present embodiment, eNB can accurately indicate for the TTI position that sends the professional follow-up data of MBMS by indication information, makes things convenient for UE to determine when reading out data, thereby saves the terminal energy consumption.
In the embodiment of the method for above-mentioned transmission business datum, eNB is by indication information scheduled transmission business datum, can within a dispatching cycle, send a plurality of MBMS data, solved in the prior art eNB under single cell transmission pattern can only dispatch a business datum within a dispatching cycle problem, so that the transmission of business datum has more flexibility, and then so that systematic function satisfies the sudden requirement of the transmission of MBMS business datum.
As shown in Figure 4, the embodiment of the invention 4 provides a kind of method that receives business datum, can comprise the steps:
Step 401: receive business datum;
Step 402: know when the base station sends this professional follow-up data in current dispatching cycle, receive this professional follow-up data.
In the embodiment of the invention, UE can in time be known the TTI information that receives business datum, has shortened the UE listening period, and then saves the terminal energy consumption.
Be described in detail below by 5 to embodiment 6 pairs of above-described embodiments 4 of the embodiment of the invention.
Suppose that eNB the 2nd TTI and the 6th TTI within a certain dispatching cycle that gives an example such as embodiment 2 sends MBMS business datum and indication information, the embodiment of the invention 5 can comprise the steps:
Step 501:UE receives length and the original position of eNB by the dispatching cycle of multiple spot control channel (MCCH, Multipoint Control Channel) transmission.This step is optional step.
Receive the MBMS business datum in the 2nd TTI of step 502:UE in current dispatching cycle.
Step 503:UE knows that by reading indication information the base station sends the follow-up data of this MBMS business in current dispatching cycle.
Concrete, UE can receive the physical downlink control channel message of the 2nd TTI in the current dispatching cycle or the media interviews control head of multicast protocol Data Unit, and read wherein indication information Extend1, suppose that this indication information is 1, then UE knows that the base station also will send the follow-up data of this MBMS business in current dispatching cycle.
Step 504:UE reads the follow-up data of above-mentioned MBMS business.
Concrete, UE can monitor the 2nd TTI TTI afterwards, until the 6th TTI in current dispatching cycle receives the follow-up data of this MBMS business behind the follow-up data of knowing this MBMS business that the base station also sends in current dispatching cycle.
Step 505:UE knows that by reading indication information the base station does not send the follow-up data of this MBMS business in current dispatching cycle, and UE can not monitor the follow-up TTI in the current dispatching cycle.
Concrete, UE can read the indication information Extend1 that the physical downlink control channel message of the 6th TTI comprises, suppose that this indication information is 0, then UE is known the TTI that does not exist in the current dispatching cycle for the follow-up data of this MBMS business of transmission, and UE can stop to monitor until next dispatching cycle.
In the present embodiment, when UE can not exist for the TTI of the follow-up data of this MBMS business of transmission, stop the monitoring to the follow-up TTI in the current dispatching cycle in knowing current dispatching cycle, thereby shorten the UE listening period, and then save the terminal energy consumption.
The embodiment of the invention 6 is similar to Example 5, and difference is, UE receives this business follow-up data according to the base station of knowing sends professional follow-up data in current dispatching cycle TTI position.In the present embodiment, suppose that eNB the 2nd TTI and the 6th TTI within a certain dispatching cycle that gives an example such as embodiment 3 sends MBMS business datum and indication information.
Concrete, the 501-502 of the step 601-602 of the present embodiment and embodiment 5 is similar, repeats no more.The step 603-605 of the present embodiment can be specific as follows:
Step 603:UE knows that by reading indication information the base station sends the TTI position of the follow-up data of this MBMS business in current dispatching cycle.
Concrete, UE can receive the physical downlink control channel message of the 2nd TTI in the current dispatching cycle or the media interviews control head of multicast protocol Data Unit, and reads indication information Extend2 wherein.UE can be according to understanding Extend2 with the indication information indicating mode of eNB agreement.For example, the sequence number value of Extend2 direct representation TTI position supposes that this Extend2 is 11, and then UE knows that 4th TTI of base station in current dispatching cycle sent the follow-up data of this MBMS business.And for example, UE can obtain the TTI position according to the value of Extend2 in the indication tabulation of self preserving or can inquire.It is 1 that the content of supposing this indication tabulation comprises Extend2, the 4th TTI in the corresponding current dispatching cycle; Extend2 is 2, the 6th TTI in the corresponding current dispatching cycle.Suppose that then it is 2 that UE receives this Extend2, know the follow-up data that has this MBMS business in the 6th TTI in the current dispatching cycle by tabulation.For another example, UE can obtain to calculate according to the value of Extend2 the location interval parameter of TTI position in the location interval tabulation of self preserving or can inquire.It is 1 that the content of supposing the tabulation of above-mentioned location interval comprises the Extend2 value, and corresponding location interval parameter is 3; The Extend2 value is 2, and corresponding location interval parameter is 4; Suppose that the Extend2 value that UE receives is 2, then UE knows that the TTI that sends professional follow-up data in the current dispatching cycle is the 6th TTI.
Step 604:UE reads the follow-up data of above-mentioned MBMS business.
Concrete, UE can select not monitor in the 3rd to the 5th TTI or part is monitored the MBMS business, and UE monitors and receives the follow-up data of this MBMS business when the 6th TTI, thereby reduces the time that UE monitors, and reduces energy consumption.
Step 605:UE knows that by reading indication information the base station does not send the follow-up data of this MBMS business in current dispatching cycle, and UE can not monitor the follow-up TTI in the current dispatching cycle.
Concrete, the physical downlink control channel message that UE receives in the 6th TTI or the media interviews control head of multicast protocol Data Unit do not comprise indication information, perhaps indication information is nul1, thereby know the TTI that does not exist in the current dispatching cycle for sending follow-up data, UE can not monitor the follow-up TTI in the current period.
The tabulation of the indication tabulation of UE storage and/or location interval is identical with the respective list of eNB storage in the present embodiment, can be eNB and UE through consultation or the mode such as agreement regulation jointly definite, also can offer UE by eNB; Above-mentioned tabulation also can provide inquiry by the storage of other network entities and for UE and/or eNB.In addition, if the TTI position that UE determines according to above-mentioned tabulation outside current dispatching cycle, then UE can be considered as this indication information invalidly, and does not operate according to this indication information.
In embodiments of the present invention, UE is known the position of reading the MBMS business datum according to indication information, thereby saves energy consumption.
Need to prove, the method that eNB arranges indication information among above-described embodiment 2 and the embodiment 3 can combine, for example, the method that provides by embodiment 2 is determined the implication of a part of indication information, the method that provides by embodiment 2 is determined the implication of another part indication information, eNB also can use eNB among above-mentioned two embodiment that the method for indication information is set simultaneously, for example preferentially understands in which way indication information by extended field or message informing UE.Similarly, the method that UE reads indication information among above-described embodiment 5 and the embodiment 6 also can combine or use simultaneously, repeats no more.In addition, UE can combine with the method for the TTI position reception MBMS business datum of eNB agreement in UE determines to receive behind the TTI position professional follow-up data according to the indication information that reads method and the prior art, UE can select when to read indication information and receive the MBMS business datum according to indication information, and when directly receives the MBMS business datum in the TTI position of agreement.
