Embodiment
In order to make the purpose, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the drawings and specific embodiments.
Method provided by the present invention mainly comprises: the base station selects one of them member carrier to be used to dispose the measurement gap of an alien frequencies or different system cell in the polymerization carrier wave, and the configuration information that will measure gap is notified to terminal, so that stop data or signaling transmission among the measurement gap of terminal on the member carrier of above-mentioned selection.
Said method is mainly used in the LTE-A system, also can be applied to the system that other adopts carrier aggregation technology.
When terminal exists alien frequencies that a plurality of needs measure or different system cell, can select member carrier to come allocating and measuring gap respectively at a plurality of alien frequencies or different system cells that need to measure respectively, it also can be a plurality of that the member carrier of selecting can be one, promptly can a plurality of alien frequencies or different system cell is common uses a member carrier, also can a plurality of alien frequencies or different system cell use different member carriers respectively.Usually as far as possible the measurement gap with a plurality of alien frequencies or different system cell correspondence staggers in time, and the member carrier that guarantees to occur simultaneously to measure gap is counted minimum.
Wherein, the base station can all be notified to terminal together with the configuration information of the measurement gap on this member carrier with the member carrier information selected; Also can only the configuration information of measuring gap be notified to terminal, terminal adopts identical selection strategy to select the member carrier at this measurement gap place with the base station.
Owing under the polymerization carrier wave mechanism of LTE-A system, use a plurality of receivers for discontinuous member carrier terminal, the corresponding member carrier of each receiver also works alone; For continuous member carrier, can only use a broadband receiver, the reception bandwidth of this broadband receiver covers the frequency range of all member carriers.At different receiver types, for several embodiment said method is described in detail respectively below.
Embodiment one, in the polymerization carrier wave of LTE-A system, terminal pins all has independently receiver to each member carrier.
The flow chart of the allocating and measuring gap that Fig. 2 provides for the embodiment of the invention one as shown in Figure 2, can may further comprise the steps:
Step 201: the definite alien frequencies that will measure in base station or the carrier frequency of different system cell, the selective reception bandwidth covers the pairing member carrier of receiver of this carrier frequency.
Step 202: judge whether the member carrier of selecting is one, if not, execution in step 203, if, execution in step 204.
Step 203: the member carrier of therefrom selecting a volume of transmitted data minimum.
Step 204: the base station is allocating and measuring gap on the member carrier of this selection.
Step 205: judge whether also to exist other alien frequencies that need measure or different system cell, if not, execution in step 206, if, execution in step 201.
If this terminal only exists the alien frequencies that will measure or different system cell, then the base station after selecting member carrier, the configuration of on this member carrier, measuring gap, and the configuration information that will measure gap is notified to terminal.
When having a plurality of alien frequencies that will measure or different system cell, the base station can be that each alien frequencies or different system cell are selected member carrier according to above-mentioned selection strategy one by one, and on the member carrier of each selection at different alien frequencies or different system cell allocating and measuring gap, and the configuration information of the measurement gap of each alien frequencies or different system cell is notified to terminal.In this process, the measurement gap on a plurality of member carriers is staggered in time as far as possible, guarantee that the member carrier of the gap of appearance measurement is simultaneously counted minimum.
Step 206: the configuration information of gap is measured in the base station by RRC signaling terminal.
In this step, the base station can be notified to the configuration information that terminal is measured gap by the RRC means of signaling.
Further, the base station can be before the configuration information that will measure gap be notified to terminal, adopt broadcasting mode, by the RRC means of signaling carrier wave selection strategy that allocating and measuring gap is adopted is notified to all terminals.Perhaps base station and terminal adopt unified carrier wave selection strategy according to default agreement, and base station and terminal are passed through the member carrier that this carrier wave selection strategy is determined allocating and measuring gap separately, and the configuration information that gap is only just measured in the base station is notified to terminal.
Be notified to terminal if only will measure the configuration information of gap, then terminal selects to measure the member carrier at gap place according to the selection strategy identical with the base station.In addition, if the unified in advance carrier wave selection strategy of base station and terminal, the base station can also be notified to terminal together with the configuration information of the measurement gap on this member carrier with the member carrier information selected.Wherein, the configuration information of measuring gap can comprise: measure gap length, cycle, time and at alien frequencies or different system cell sign.
Terminal can only stop data and signaling transmission in the measurement gap of the member carrier of selecting, according to the configuration of measuring gap on this member carrier alien-frequency district or system cell are measured, and continues data and signaling transmission in other member carrier.That is to say, measure data and signaling transmission that gap only influences the member carrier at its place.Promptly the pairing receiver of the member carrier of Xuan Zeing stops data and signaling transmission in measuring gap, and the pairing receiver of other member carrier can carry out the transmission of data and signaling always.
Embodiment two, in the polymerization carrier wave of LTE-A system, terminal pins adopts same broadband receiver to all member carriers, and the carrier frequency of alien frequencies of need measuring or different system cell is in the operating frequency of the polymerization carrier wave of LTE-A system.
The flow chart of the allocating and measuring gap that Fig. 3 provides for the embodiment of the invention two as shown in Figure 3, can may further comprise the steps:
Step 301: the member carrier of a volume of transmitted data minimum is selected in the base station from the polymerization carrier wave of LTE-A system.
In this embodiment because terminal has only a broadband receiver, therefore, the strategy of base station selected member carrier and embodiment are inequality in the lump, except can from the polymerization carrier wave, selecting the member carrier of a volume of transmitted data minimum, can also select the member carrier of bandwidth minimum, perhaps, perhaps select a member carrier etc. arbitrarily at the poorest member carrier of this terminal channel quality.
Step 302: the base station disposes the alien frequencies that will measure or the measurement gap of different system cell on the member carrier of this selection.
Step 303: judge whether also to exist other alien frequencies that need measure or different system cell, if not, execution in step 304, if, execution in step 301.
Equally, if this terminal only exists the alien frequencies that will measure or different system cell, then the base station after selecting member carrier, the configuration of on this member carrier, measuring gap, and the configuration information that will measure gap is notified to terminal.
When having a plurality of alien frequencies that will measure or different system cell, the base station can be that an alien frequencies or different system cell are selected member carrier according to above-mentioned selection strategy one by one, and on the member carrier of each selection at different alien frequencies or different system cell allocating and measuring gap, and the configuration information of the measurement gap of each alien frequencies or different system cell is notified to terminal.In this process, the measurement gap on a plurality of member carriers is staggered in time as far as possible, guarantee that the member carrier of the gap of appearance measurement is simultaneously counted minimum.
Step 304: the configuration information of gap is measured in the base station with RRC signaling terminal.
In this step, the base station can be notified to the configuration information that terminal is measured gap by the RRC means of signaling.
Further, the base station can be before the configuration information that will measure gap be notified to terminal, adopt broadcasting mode, by the RRC means of signaling carrier wave selection strategy that allocating and measuring gap is adopted is notified to all terminals.Perhaps base station and terminal adopt unified carrier wave selection strategy according to default agreement, and base station and terminal are passed through the member carrier that this carrier wave selection strategy is determined allocating and measuring gap separately, and the configuration information that gap only will be measured in the base station is notified to terminal.
Be notified to terminal if only will measure the configuration information of gap, then terminal selects to measure the member carrier at gap place according to the selection strategy identical with the base station.In addition, if the unified in advance carrier wave selection strategy of base station and terminal, the base station can also be notified to terminal together with the configuration information of the measurement gap on this member carrier with the member carrier information selected.Wherein, the configuration information of measuring gap can comprise: measure gap length, cycle, time and at alien frequencies or different system cell sign.
Terminal can only stop data and signaling transmission in the measurement gap of the member carrier of selecting, according to the configuration of measuring gap on this member carrier alien-frequency district or system cell are measured, and continues data and signaling transmission in other member carrier.That is to say, measure data and signaling transmission that gap only influences the member carrier at its place.
Embodiment three, in the polymerization carrier wave of LTE-A system, terminal pins adopts same broadband receiver to all member carriers, and the carrier frequency of the alien frequencies that will measure or different system cell is not in the operating frequency of the polymerization carrier wave of this LTE-A system.
Still there are following two kinds of situations in this embodiment:
First kind of situation: all member carriers of the alien frequencies that measure or the carrier frequency of different system cell and LTE-A system can not be simultaneously in the reception bandwidth of broadband receiver.Shown in Fig. 4 a, the reception bandwidth of supposing receiver is 100MHz, have two member carriers in the LTE-A system: centre frequency is the member carrier 1 of f1 and the member carrier 2 that centre frequency is f1+80MHz, and the carrier frequency of alien frequencies or different system cell is f1-100MHz.At this moment, behind terminal configuration measurement gap, measure gap as long as enter, terminal just can not be operated in the operating frequency of this sub-district of LET-A system, and this situation is the same with the LTE system.
Second kind of situation: after adjusting the broadband receiver centre frequency, the alien frequencies that measure or the carrier frequency of different system cell and part member carrier can be simultaneously in the reception bandwidth of broadband receiver.Shown in Fig. 4 b, the reception bandwidth of supposing receiver is 100MHz, have two member carriers in the LTE-A system: centre frequency is the member carrier 1 of f1 and the member carrier 2 that centre frequency is f1+80MHz, and the carrier frequency of alien frequencies or different system cell is f1+100MHz.
If do not allow to adjust the centre frequency of broadband receiver, then, measure gap as long as enter for behind the terminal configuration measurement gap, terminal just can not be transmitted the data of LTE-A system cell, and this situation is the same with the LTE system.
If allow to adjust the centre frequency of broadband receiver, then can select can not with the carrier frequency of the alien frequencies that will measure or the different system cell member carrier in the reception bandwidth of the broadband receiver after adjusting centre frequency simultaneously, allocating and measuring gap on the member carrier of this selection, if it is a plurality of that the member carrier of selecting exists, then can therefrom choose an allocating and measuring gap wantonly.That is to say, even select to adjust the centre frequency of receiver, can not with the carrier frequency of the alien frequencies that will measure or the different system cell member carrier in the reception bandwidth of bandwidth receiver simultaneously, allocating and measuring gap on this member carrier.
Equally, if this terminal only exists the alien frequencies that will measure or different system cell, then the base station after selecting member carrier, the configuration of on this member carrier, measuring gap, and the configuration information that will measure gap is notified to terminal.
When having a plurality of alien frequencies that will measure or different system cell, the base station can be that an alien frequencies or different system cell are selected member carrier according to above-mentioned selection strategy one by one, and on the member carrier of each selection at different alien frequencies or different system cell allocating and measuring gap, and the configuration information of the measurement gap of each alien frequencies or different system cell is notified to terminal.In this process, the measurement gap on a plurality of member carriers is staggered in time as far as possible, guarantee that the member carrier of the gap of appearance measurement is simultaneously counted minimum.
The base station can be measured the configuration information of gap by RRC means of signaling notice terminal.
Further, the base station can be before the configuration information that will measure gap be notified to terminal, adopt broadcasting mode, by the RRC means of signaling carrier wave selection strategy of allocating and measuring gap is notified to all terminals.Perhaps base station and terminal adopt unified carrier wave selection strategy according to default agreement, and base station and terminal are passed through the member carrier that this carrier wave selection strategy is determined allocating and measuring gap separately, and the configuration information that gap only will be measured in the base station is notified to terminal.
Be notified to terminal if only will measure the configuration information of gap, then terminal selects to measure the member carrier at gap place according to the carrier wave selection strategy identical with the base station.In addition, if the unified in advance carrier wave selection strategy of base station and terminal, the base station can also be notified to terminal together with the configuration information of the measurement gap on this member carrier with the member carrier information selected.Wherein, the configuration information of measuring gap can comprise: measure gap length, cycle, time and at alien frequencies or different system cell sign.
Terminal can only stop data and signaling transmission in the measurement gap of the member carrier of selecting, according to the configuration of measuring gap on this member carrier alien-frequency district or system cell are measured, and continues data and signaling transmission in other member carrier.That is to say, measure data and signaling transmission that gap only influences the member carrier at its place.
More than be the detailed description that method provided by the present invention is carried out, below base station provided by the present invention and terminal be described in detail.
The architecture of base station figure that Fig. 5 provides for the embodiment of the invention, as shown in Figure 5, this base station can comprise: carrier wave selected cell 501, measurement gap dispensing unit 502 and information notification unit 503.
Carrier wave selected cell 501 is used for the polymerization carrier wave in the LTE-A system, is that terminal is selected one of them member carrier according to the carrier wave selection strategy.
Measure gap dispensing unit 502, be used on the member carrier that carrier wave selected cell 501 is selected, disposing the measurement gap of an alien frequencies or different system cell.
Wherein, if terminal pins all has independently receiver to each member carrier in the polymerization carrier wave of LTE-A system, then carrier wave selected cell 501 can be according to the carrier frequency of the alien frequencies that will measure or different system cell, a member carrier in the pairing member carrier of receiver of selective reception bandwidth covering carrier frequency.
If terminal pins is all used same receiver to all member carriers in the polymerization carrier wave of LTE-A system, and the alien frequencies of measuring or the carrier frequency of different system cell are in the reception bandwidth of this receiver, then carrier wave selected cell 501 can be selected a member carrier arbitrarily from the polymerization carrier wave, perhaps select the member carrier of a volume of transmitted data minimum, perhaps select the member carrier of a bandwidth minimum, perhaps select one at the poorest member carrier of terminal channel quality.
If terminal pins is all used same receiver to all member carriers in the polymerization carrier wave of LTE-A system, and the alien frequencies of measuring or the carrier frequency of different system cell be not in the reception bandwidth of this receiver, after then carrier wave selected cell 501 can be selected to adjust the broadband receiver centre frequency, still can not with the carrier frequency of the alien frequencies that will measure or the different system cell member carrier in the reception bandwidth of broadband receiver simultaneously, allocating and measuring gap on this member carrier.
When having a plurality of alien frequencies that will measure or different system cell, this base station can also comprise: judging unit 504, be used for after measuring gap dispensing unit 502 execution configuration operations, judge whether also to exist other alien frequencies that will measure or different system cell, if then notify carrier wave selected cell 501 to continue to select member carrier at other alien frequencies that will measure or different system cell; If not, the configuration information that then will measure gap offers information notification unit 503.
At this moment, measure gap dispensing unit 502, if can also be used for existing the alien frequencies or the different system cell of a plurality of measurements, then at each alien frequencies or the selected member carrier of different system cell during allocating and measuring gap, the time of measuring gap on each member carrier is staggered, make the member carrier that occurs measurement gap simultaneously count minimum.
In addition, the information notification unit 503 member carrier information that can also be used for selecting when the configuration information that will measure gap is notified to terminal is notified to terminal.
Wherein, information notification unit 503 configuration information that will measure gap be notified to terminal mode can for: give terminal by the RRC signaling.
In addition, information notification unit 503 can also be before the configuration information that will measure gap be notified to terminal, adopt broadcasting mode, by the RRC means of signaling carrier wave selection strategy that allocating and measuring gap is adopted is notified to all terminals.Perhaps base station and terminal adopt unified carrier wave selection strategy according to default agreement.
The terminal structure figure that Fig. 6 provides for the embodiment of the invention, as shown in Figure 6, this terminal can comprise: information receiving unit 601, carrier wave determining unit 602 and measurement processing unit 603.
Carrier wave determining unit 602 is used for the member carrier at the measurement gap of the polymerization carrier wave of LTE-A system alien frequencies of having determined base station configuration or different system cell.
Wherein, carrier wave determining unit 602 can be according to the member carrier of the measurement gap of carrier wave selection strategy alien frequencies of having determined base station configuration or different system cell.
Perhaps, information receiving unit 601 can also be used to be received as the member carrier information of alien frequencies or the selection of different system cell; At this moment, the member carrier information that carrier wave determining unit 602 can receive according to information receiving unit, the member carrier of the measurement gap of determined a base station configuration alien frequencies or different system cell.
Particularly, if terminal pins all has independently receiver to each member carrier in the polymerization carrier wave of LTE-A system, then carrier wave determining unit 602 can be according to the carrier frequency of the alien frequencies that will measure or different system cell, a member carrier in the pairing member carrier of receiver of selective reception bandwidth covering carrier frequency.In such cases, the receiver of this member carrier correspondence stops the transmission of data or signaling in measuring gap, carry out the measurement of alien frequencies or different system cell, and other receiver is also influenced.
If terminal pins is all used same receiver to all member carriers in the polymerization carrier wave of LTE-A system, and the alien frequencies of measuring or the carrier frequency of different system cell are in the reception bandwidth of this receiver, then carrier wave determining unit 602 can be selected a member carrier arbitrarily from the polymerization carrier wave, perhaps select the member carrier of a volume of transmitted data minimum, perhaps select the member carrier of a bandwidth minimum, perhaps select one at the poorest member carrier of terminal channel quality.
If terminal pins is all used same receiver to all member carriers in the polymerization carrier wave of LTE-A system, and the alien frequencies of measuring or the carrier frequency of different system cell be not in the reception bandwidth of this receiver, after then carrier wave determining unit 602 can be selected to adjust the broadband receiver centre frequency, still can not with the carrier frequency of the alien frequencies that will measure or the different system cell member carrier in the reception bandwidth of broadband receiver simultaneously, allocating and measuring gap on this member carrier.
By above description as can be seen, the base station is in the polymerization carrier wave of LTE-A system, select one of them member carrier to dispose the measurement gap of an alien frequencies or different system cell according to the carrier wave selection strategy, and the configuration information that will measure gap is notified to terminal, be that allocating and measuring gap is come at single member carrier in the base station, make terminal only need in the measurement gap on having disposed the member carrier of measuring gap, stop data or signaling transmission, can not impact other member carrier, terminal can also be in the transmission of enterprising line data of other member carrier and signaling, thereby has improved data transmission quality and power system capacity.
