Technical field

The present invention relates to moving communicating field, particularly, the present invention relates to the method and apparatus that a kind of system information sends, receives.

Background technology

Mobile and broadband becomes the developing direction of modern communication technology, 3GPP (3rd GenerationPartnership Project, third generation partner program) be devoted to the evolution of 3G system, target is development 3GPP wireless access technology towards high data rate, lowly postpones and optimize the evolution of packet data application direction.3GPP is at LTE-A (Long Term Evolution-Advanced, Long Term Evolution is senior) in the system, require peak rate than LTE (Long Term Evolution, Long Term Evolution) system huge raising to be arranged, requirement reaches descending 1Gbps, up 500Mbps.On single carrier wave, can't satisfy this demand, therefore introduce CA (Carrier Aggregation in the LTE-A system, carrier aggregation) technology, be under the same base station, continuous or discrete a plurality of carrier waves are concentrated in together, multicarrier is Terminal Service simultaneously when needed, so that required frequency resource to be provided, each carrier wave that participates in CA is called member carrier (Component Carrier, be called for short CC), each member carrier may be corresponding to a residential quarter that can work alone, also may be corresponding to a carrier resource that can not work alone.Can both work under each CC for the terminal that guarantees LTE, each CC maximum is no more than 20MHz.The CA technology of LTE-A as shown in Figure 1, the LTE-A base station polymerization among Fig. 14 carrier waves.Transfer of data can be carried out with terminal simultaneously in the base station on 4 carrier waves, to improve throughput of system.In the LTE-A system, under the common base station administration one or more residential quarters (cell), and each residential quarter can be regarded a member carrier as.

For the LTE-A terminal, can see simultaneously four carrier waves, network can be according to the requirement of customer service speed, and the resource of dispatching one or more carrier wave is this Terminal Service.For the LTE terminal, only can see there are 4 residential quarters that they are adjacent cell each other each other.In order to make the normal operation of LTE terminal, need to broadcast the system information of this CC at each CC.

In the LTE system, the main contents of system information broadcast comprise:

Host system message block (MIB), major parameter has: downlink bandwidth, the configuration information of PHICH, System Frame Number (SFN);

System information block 1 (SIB1), main contents have: the information (PLMNID relevant with the residential quarter access, TAC, cell ID etc.), select relevant parameter with the residential quarter, maximum transmission power, band information, the schedule information of system information, TDD configuration parameter, the SI length of window, systemInfoVal terminal Tag etc.;

System information block 9 (SIB9) only carries the identification information of home node b;

System information block 10 (SIB10) carries the main notice for early warning ETWS, comprises message identification numbers, sequence number, alarm type, alarm security information etc.;

System information block 11 (SIB11) carries the assistant notification for early warning ETWS, comprises message identification numbers, sequence number, the segment information of alarm information, fragment number, section, data coding scheme etc.

In said system information, in the LTE system, the terminal of RRC_CONNECTED state will be carried out data transmit-receive, just must know the MIB of current area, SIB1 and SIB2 message.In the LTE-A system, under the base station a plurality of CC are arranged, consider the requirement of compatible LTE terminal, need to broadcast one on each CC and overlap independently system information, and the system information on each CC may be different: such as frequency information, the configuration of PHICH etc.Therefore, the LTE-A terminal need to be obtained the upper up-to-date system information of each CC before a plurality of CC of use carry out transfer of data.

Carrier sense mechanism in the LTE system is: Fig. 2 is the structural representation of descending sub frame, wherein, each descending sub frame is comprised of the OFDM symbol, front several OFDM symbols of descending sub frame are control character, be used for the bearing downlink control signal, the channel of bearing downlink control signal is called the PDCCH channel.All the other OFDM symbols carry downlink datas, the physical layer channel of bearing downlink data is called the PDSCH channel.Control signal comprises: to the schedule information of this descending sub frame and corresponding sub-frame of uplink and relevant HARQ information etc.Terminal determines whether distributed resource in corresponding subframe by the control signal that receives descending sub frame.If distributed resource, terminal obtains the temporal frequency position of resource according to the indication of dispatch, and carries out the data transmitting-receiving.In the LTE system, each residential quarter only has a descending carrier, so terminal only need to be monitored PDCCH and a PDSCH on the descending carrier.

In the LTE-A system, introduced the CA technology, a base station possible configuration a plurality of CC, N for example.The terminal of LTE-A may use M CC to carry out transfer of data simultaneously, and wherein M is less than or equal to N.When the data volume of LTE-A terminal transmitting-receiving is larger, need carry out transfer of data at many CC simultaneously.This moment, terminal was monitored PDCCH and the PDSCH on a plurality of CC simultaneously.In the little situation of terminal data amount, monitoring simultaneously a plurality of CC has not just had too many necessity.Stop to be conducive to terminal power saving to the receiving the decode of obsolete CC.In order to make things convenient for following description, CC or CC group that terminal is received the decode are defined as Anchor CC.

Therefore, the carrier sense mechanism in the LTE-A system is: generally, and PDCCH and PDSCH on the terminal monitoring Anchor CC; When having mass data to receive and dispatch, the CC that network is being monitored by terminal sends control signaling to terminal, requires terminal to increase the quantity of the CC that monitors; After terminal is received above-mentioned signaling, start the monitoring of corresponding CC; Network and terminal communicate at a plurality of CC.

Terminal has a precondition in the enterprising row data transmitting-receiving of CC: terminal need to be known the up-to-date system information of this CC.But each CC only can broadcast system information corresponding to this CC, and UE only can monitor Anchor CC before the control signal of receiving the activation CC monitoring that network sends.This has just caused UE receiving when activating the control signal that CC monitors, and may not know the up-to-date system information of the CC that is activated.

If terminal just begins to receive the system information on the corresponding CC after receiving that CC activates signaling, then before the reception of completion system information, terminal can not be on this CC transceiving data.The transmission of system information is periodic, and the transmission cycle of MIB and each SIB is not waited from tens to the hundreds of millisecond.That is to say, after terminal receives that CC activates signaling, may need the system information through dozens or even hundreds of millisecond to read after the process, could be in the enterprising row data transmitting-receiving of corresponding CC.As seen, if terminal after receiving that CC activates signaling, just begins to receive the system information on the corresponding CC, with introducing larger time delay, in order to address this problem, in the LTE-A system, introduced following system information monitoring mechanism.

System information monitoring mechanism in the LTE-A system is: introduced the CA technology in the LTE-A system, the terminal of LTE-A is in order to receive and dispatch by rapid data on a plurality of CC, after need to or switching to new LTE-A residential quarter in access LTE-A residential quarter, read immediately the system information on the relevant CC.And behind generation systems information-change on each CC, again read the system information on this CC.This mechanism requires the terminal of LTE-A can in time obtain system information Notification of Changes on each CC of current base station.

When terminal communicates with the base station on M CC simultaneously, need to safeguard simultaneously the recent systems information on these CC, if monitor simultaneously the system information of all CC always, concerning UE, also there is no need, be unfavorable for terminal power saving.

The informing mechanism of the system information change in the LTE system is: except ETWS (Earthquake andTsunami Warning System, earthquake and tsunami warning system) outside the message, the change of system information can only occur in specific radio frames, and is definite by the modification cycle (modification period).Within a modification cycle, system information may send repeatedly, and the system information content that repeatedly sends is identical.System information can only change after the border in the cycle of modification, and the boundary definition of revising the cycle is as follows: SFN mod m=0.Wherein, SFN is System Frame Number, and m is the modification cycle, and unit is radio frames.

When network need to change all or part of system information, it at first needed to send " system information change indication " to terminal, and notification terminal changes the system information that occurs, and notification procedure may need to continue a modification cycle.Revise the cycle at the next one, network just can send the system information after the renewal.Above-mentioned rule is system information change schematic diagram as shown in Figure 3.After receiving system information change indication, terminal is revised the system information after locating to read renewal of beginning in cycle immediately at the next one.Before terminal was obtained new system, terminal continued to use old system information.

Network comes to send " system information change indication " to the terminal that is in RRC_IDLE and RRC_CONNECTED state with beep-page message.If terminal has been received the beep-page message that comprises " systemInfoModification ", can revise the boundary in cycle at the next one and change with regard to knowing system information." system information change indication " only can the notification terminal system information will change, and can not indicate which or which system information to change to terminal.

The change of some system information can not trigger the transmission of the beep-page message that comprises " systemInfoModification ", such as the change of ETWS.Terminal can determine by the following method whether the system information of depositing is effective, in the situation of not receiving the systemInfoModification indication, terminal need to be within a modification cycle, at least read beep-page message modificationPeriodCoeff time, in the hope of finding the systemInfoModification indication.

If do not read beep-page message, terminal thinks that system information will can not change within the next one modification cycle.If terminal reads the beep-page message that comprises the systemInfoModification indication, just think that system information will change in the next one is revised the cycle.The introducing of systemInfoModification can be avoided frequently read system information of terminal, reduces the power consumption of terminal.

In addition, the LTE system triggers called service with paging and the notification terminal system information is about to change.Beep-page message is dispatched by P-RNTI.Terminal in the network is decoded to the PDCCH channel specific constantly, obtains beep-page message.PDCCH DCI form corresponding to P-RNTI is format 1a and format 1c at present.DCI refers to Downlink Control Information (Downlink ControlInformation).

As mentioned above, under technique scheme, the terminal of LTE-A can't in time obtain currently to provide the system information Notification of Changes of each CC of service for it.As certain service CC, calling this CC in the following text is CC_change, and when its system information changed, the beep-page message that is used for the change of notification terminal system information only can send at CC_change.If the LTE-A terminal is monitored the system information Notification of Changes of all CC simultaneously, will be unfavorable to saving electric weight, therefore, terminal may select only to monitor the system information Notification of Changes of certain CC (Anchor CC), if this Anchor CC is not CC_change, terminal can't be known has the system information of CC to change, and then to cause the system information of the CC_change that terminal preserves be not up-to-date.When network need to activate the data transmit-receive of this terminal on CC_change, terminal was used invalid CC configuration information, will cause transfer of data to make a mistake.

Therefore be necessary to propose corresponding technical scheme, terminal can realize monitoring to a plurality of CC in the resolution system, in time finds the variation of system information and the problem of upgrading.

Summary of the invention

In the LTE-A system, under the common base station administration one or more residential quarters (cell), and each residential quarter can be regarded a member carrier as.When the LTE-A terminal works in CA pattern lower time, a plurality of member carriers of UE polymerization carry out data transmit-receive, therefore, this UE needs in time upgrade the system information of these member carriers.If the LTE-A terminal is monitored the system information Notification of Changes of all CC simultaneously, will be unfavorable to saving electric weight, in an embodiment of the present invention, making UE under the CA transmission mode only monitor a polymerization CC just can carry out system information and upgrade, wherein, a described polymerization CC can be network by the signaling appointment, or the specific cell of UE (special cell), or the anchor residential quarter of UE (anchor cell), or the optional member carrier of UE.Monitoring in the embodiments of the invention refers to that UE monitors the beep-page message of certain CC, contains the system message Notification of Changes in the beep-page message.

The method of system information transmission can may further comprise the steps according to an embodiment of the invention:

Step 1, base station judge whether member carrier CC needs updating system information;

Step 2, when member's carrier wave CC_change needs updating system information, the base station sends beep-page message 1 at CC_cnange, the terminal updating system information under the notice CC_change residential quarter;

Step 3, base station other CC beyond in the CC_change base station send beep-page messages 2, notify the terminal under other base stations to have the CC updating system information.

Wherein, beep-page message 1 and beep-page message 2 can be the RRC message (only have concrete message content different) of same type, also can be two kinds of dissimilar RRC message.The base station can only send beep-page message 2 at the carrier wave that polymerization UE is arranged.

Example 1: can be by increasing a bit indication SI Change, concrete grammar comprises:

1, the base station judges whether member carrier CC needs updating system information.The base station will judge at any time whether each member carrier CC needs updating system information.

2, in the CA transmission course, when a certain member carrier CC_change needed updating system information, the base station sent beep-page message 1, the terminal updating system information under the notifying cell at carrier wave CC_change.Beep-page message 1 can be continued to use existing technical scheme in the LTE system.If UE is monitoring CC_change this moment, this UE just can receive beep-page message 1, thereby carries out system message update; If the carrier wave that UE monitors at this moment is not CC_change, UE just can't receive beep-page message 1, also just can't obtain the system message Notification of Changes of CC_change, and UE need to obtain system message update by beep-page message 2 in this case.

3, the base station only sends beep-page message 2 at the carrier wave that polymerization UE is arranged, and notice is being monitored the UE updating system information of other CC.Whether can adopt and indicate the system information on this CC other CC in addition will change the mode of a bit of beep-page message expansion, when the system information on other CC are arranged will change, this bit was set to true; Otherwise this bit is false.The message format of the beep-page message 2 after the expansion is as follows:

}

Namely, when the base station was judged CC_change with updating system information, in the BCCH modification cycle before the system information updated time, the base station was on other CC beyond the CC_change, send beep-page message 2: in the beep-page message 2, systemInfoModification-r10ext is set to true.The LTE-A terminal on the CC of current monitoring (for example, special cell or anchor cell) reading gating message, if receive beep-page message 2, and systemInfoModification-r10ext is set to true, then revise the original position in cycle at next BCCH, system information on the CC of unlisten is read again, and after the system information on finishing the CC of unlisten read, terminal was preserved these system informations.

Example 2: can indicate SI Change by increasing the bitmap mode, concrete grammar comprises:

2, in the CA transmission course, when a certain member carrier CC_change needed updating system information, the base station sent beep-page message 1, the terminal updating system information under the notifying cell at carrier wave CC_change.Beep-page message 1 can be continued to use existing technical scheme in the LTE system.If UE is monitoring CC_change at this moment, this UE just can receive beep-page message 1, thereby carry out system message update, if the carrier wave that UE monitors at this moment is not CC_change, UE just can't receive beep-page message 1, also just can't obtain the system message Notification of Changes of CC_change, UE need to obtain system message update by beep-page message 2 in this case.

3, the base station only sends beep-page message 2 at the carrier wave that polymerization UE is arranged, and notice is being monitored the UE updating system information of other CC.Beep-page message 2 is expanded beep-page message 1 to realize, by increase system information change bit pattern bitmap information, the corresponding CC of indication updating system information in beep-page message 1.When the system information that CC is arranged changed, the indication of the bit of corresponding CC was set to true among the bitmap, and the bit that the CC that system information does not change is corresponding is set to false.When other CC except this CC did not have system information to change, this bitmap can not occur.The message format of the beep-page message 2 after the expansion is as follows:

Namely, when the base station is judged CC_change with updating system information, in the BCCH modification cycle before the system information updated time, the base station is on other CC beyond the CC_change, send beep-page message 2: in the beep-page message, carry bitmap, and with among the bitmap, the bit that the CC that system information changes is corresponding is set to true; The bit that the CC that system information does not change is corresponding is set to false.The LTE-A terminal on the CC of current monitoring (for example, specific cell or anchor residential quarter) reading gating message, if receive beep-page message 2, and carried system information change bitmap, then revise the original position in cycle at next BCCH, system information on the CC that is set to true among the bitmap is read again, and after the system information on finishing corresponding CC read, terminal was preserved these system informations.

Example 3: can carry a bit mode and indicate SI Change in beep-page message corresponding to new paging ID by the new paging ID of definition, concrete grammar comprises:

3, the base station only sends beep-page message 2 at the carrier wave that polymerization UE is arranged, and notice is being monitored the UE updating system information of other CC.Beep-page message 2 realizes that by defining new paging ID this paging ID carries a bit and indicates whether to exist other CC updating system information corresponding to beep-page message 2 in the beep-page message 2.

For example, in the LTE system, beep-page message 1 is dispatched by paging ID:P-RNTI.In LTE-A, can define new paging ID:P-RNTI2.P-RNTI2 is sightless to the LTE terminal, and LTE-A in this beep-page message, comprises other CC system information change indications by to P-RNTI2 decoding paging receiving message, carries 1 bit and indicates paging former because the system information on other CC changes.

Namely, when the base station was judged CC_change with updating system information, in the BCCH modification cycle before the system information updated time, the base station was on other CC beyond the CC_change, send beep-page message: paging ID is P-RNTI2, and paging is former because the system information on other CC changes.The LTE-A terminal on the CC of current monitoring (for example, specific cell or anchor residential quarter) reading gating message, if receive beep-page message 2, and paging is former because the system information on other CC changes, then revise the original position in cycle at next BCCH, system information on the CC of unlisten is read again, and after the system information on finishing corresponding CC read, terminal was preserved these system informations.

Example 4: can carry the bitmap mode and indicate SI Change in beep-page message corresponding to new paging ID by the new paging ID of definition, concrete grammar comprises:

3, the base station only sends beep-page message 2 at the carrier wave that polymerization UE is arranged, and notice is being monitored the UE updating system information of other CC.Beep-page message 2 is for realizing that by the new paging ID of definition this paging ID carries a bitmap information, is used to indicate the corresponding CC of updating system information.The LTE-A terminal on the CC of current monitoring (for example, specific cell or anchor residential quarter) reading gating message, if receive beep-page message, and carried system information change bitmap, then revise the original position in cycle at next BCCH, system information on the CC that is set to true among the bitmap is read again, finish to the indication updating system information corresponding CC on system information read after, terminal is preserved these system informations.

Example 5: can carry a bit mode and indicate SI Change in new paging ID itself by the new paging ID of definition, concrete methods of realizing and example 3 are similar.Realize that by defining new paging ID this paging ID carries a bit information for beep-page message 2, be used to indicate whether there are other CC updating system information.But different from example 3 is, this increase bit is positioned among the new paging ID itself, that is, the LTE-A terminal need not whether the beep-page message system information that just can judge on other CC of decoding is changed.If take into account one-step optimization, beep-page message can not carry any information or not need corresponding beep-page message.In addition, the bit information that this paging ID carries can carry for implicit expression, and when new paging ID occurring on the scheduling channel, expression exists other CC that the system information change has occured, otherwise does not have other CC generation systems information-changes.

For example, in LTE-A, define new paging ID:P-RNTI2.P-RNTI2 is sightless to the LTE terminal, and the LTE-A terminal directly judges according to the form (bit of increase) of P-RNTI2 whether the system information on other CC variation has occured.For example, P-RNTI2 is the expansion to the P-RNTI of LTE, and being embodied in increases a bit to PDCCH DCI format 1a or format 1c.In addition, if the bit information that P-RNTI2 carries is that implicit expression is carried, when P-RNTI2 occurring on the scheduling channel, expression exists other CC that the system information change has occured, otherwise does not have other CC generation systems information-changes.

Other correlation step of system information sending and receiving are identical with example 3.

Example 6: can realize by the new paging ID of definition, in new paging ID itself, carry the bitmap mode and indicate SI Change, concrete grammar and example 4 are similar, realize by defining new paging ID for beep-page message 2, this paging ID carries a bitmap information, is used to indicate the corresponding CC of updating system information.But different from example 4 is, this bitmap information is positioned among the new paging ID itself, that is, the LTE-A terminal need not variation has been occured the beep-page message system information that just can judge on which CC of decoding.If take into account one-step optimization, beep-page message can not carry any information or not need corresponding beep-page message.

For example, in LTE-A, defining new paging ID is P-RNTI2.P-RNTI2 is sightless to the LTE terminal, and the LTE-A terminal directly judges that according to the form (the bitmap information of increase) of P-RNTI2 variation has occured the system information on which CC.For example, P-RNTI2 is the expansion to the P-RNTI of LTE, and being embodied in increases bitmap information to PDCCH DCI format 1a.

Other correlation step of system information sending and receiving are identical with example 4.

Example 7: can indicate SI Change by increasing carrier index (CC Index), concrete grammar comprises:

3, the base station only sends beep-page message 2 at the carrier wave that polymerization UE is arranged, and notice is being monitored the UE updating system information of other CC.Can adopt the mode that beep-page message is expanded carrier index to indicate the system information on other CC beyond this CC whether will change, when the system information on other CC are arranged will change, the carrier index of this CC of notice UE; Otherwise, do not notify the carrier index of this CC of UE.The message format of the beep-page message 2 after the expansion is as follows:

}

Namely, when the base station is judged CC_change with updating system information, in the BCCH modification cycle before the system information updated time, the base station is on other CC beyond the CC_change, send beep-page message 2: in the beep-page message 2, CC-SystemInfoModification comprises the carrier index (CC Index) of CC_change.The LTE-A terminal on the CC of current monitoring (for example, special cell or anchor cell) reading gating message, if receive beep-page message 2, and CC-SystemInfoModification comprises the carrier index (CC Index) of CC_change, then revise the original position in cycle at next BCCH, system information on the CC_change that has obtained carrier index is read again, after system information on finishing CC_change read, terminal was preserved these system informations.

Example 8: can increase carrier index (CC Index) and indicate SI Change in beep-page message corresponding to new paging ID by the new paging ID of definition, concrete grammar comprises:

3, the base station only sends beep-page message 2 at the carrier wave that polymerization UE is arranged, and notice is being monitored the UE updating system information of other CC.Beep-page message 2 realizes by defining new paging ID, and the carrier index (CC Index) of carrying system information updating CC is used to indicate whether there are other CC updating system information in beep-page message 2 corresponding to this paging ID.Identical in the form of beep-page message 2 and the example 7.

For example, in the LTE system, beep-page message 1 is dispatched by paging ID:P-RNTI.In LTE-A, can define new paging ID:P-RNTI2.P-RNTI2 is sightless to the LTE terminal, LTE-A is by paging receiving message that P-RNTI2 is decoded, in this beep-page message, comprise other CC system information change indications, carry carrier index (CC Index) and indicate the system information of which other CC that variation has occured.

Namely, when the base station is judged CC_change with updating system information, in the BCCH modification cycle before the system information updated time, the base station is on other CC beyond the CC_change, send beep-page message: paging ID is P-RNTI2, the carrier index of carrying CC_change in the corresponding beep-page message, the system information on the expression CC_change changes.The LTE-A terminal on the CC of current monitoring (for example, special cell or anchor cell) reading gating message, if receive beep-page message 2, and carried the carrier index (CC Index) of CC_change in the beep-page message, the system information of indication CC_change changes, then revise the original position in cycle at next BCCH, system information to CC_change reads again, after system information on finishing CC_change read, terminal was preserved these system informations.

Example 9: can carry carrier index (CCIndex) and indicate SI Change in new paging ID itself by the new paging ID of definition, concrete methods of realizing and example 8 are similar.Realize by defining new paging ID that for beep-page message 2 this beep-page message 2 carries carrier index (CC Index) information, be used to indicate whether there are other CC updating system information.But different from example 8 is, this increase carrier index (CC Index) is positioned among the new paging ID itself, that is, the LTE-A terminal need not whether the beep-page message system information that just can judge on other CC of decoding is changed.If take into account one-step optimization, beep-page message can not carry any information or not need corresponding beep-page message.In addition, the carrier index that this paging ID carries (CC Index) can be reused existing carrier index indication information, for example CI bits (CI is carrier index).If the carrier index of having carried certain CC among the new paging ID so just identifies this CC the system information renewal has occured.

For example, in LTE-A, define new paging ID:P-RNTI2.P-RNTI2 is sightless to the LTE terminal, and the LTE-A terminal directly judges according to the form (carrier index of increase) of P-RNTI2 whether the system information on other CC variation has occured.For example, P-RNTI2 is the expansion to the P-RNTI of LTE, and being embodied in increases carrier index to PDCCH DCI format 1a or format 1c.

Other correlation step of system information sending and receiving are identical with example 8.

In addition, the said equipment that the embodiment of the invention proposes has solved that terminal can realize monitoring to a plurality of CC in the system, in time find the variation of system information and the problem of upgrading.According to the said equipment that the embodiment of the invention proposes, terminal both can in time find the variation of a plurality of CC system informations and upgrade, and also can not monitor a plurality of CC for a long time because of updating system information and increased the power consumption of terminal.In addition, the said equipment that the embodiment of the invention proposes, very little to the change of existing system, can not affect the compatibility of system, and realize simple, efficient.

The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
