Embodiment
In order to make those skilled in the art person understand better the scheme of the embodiment of the present invention, below in conjunction with drawings and embodiments, the embodiment of the present invention is described in further detail.
Embodiment of the present invention component carrier management method and equipment, for have relay equipment or RRU (Remote RF Unit, remote radio unit (RRU)) equipment in system time, can not guarantee to use on multiple component carriers the situation of identical TA:
For example, as shown in Figure 2, base station has configured different component carriers on different repeaters, or the component carrier of different frequency has passed through different scattering paths.Under this situation, the required TA of different component carriers is different.
Again for example, as shown in Figure 3, to cover or strengthen throughput of system in order to expand, UE uses the access point (refer to be connected by optical fiber etc. from base station far-end radio-cell) of two different component carriers and two non-cooperations to communicate by letter.Two websites have been arranged respectively two far-end aerial heads or distributed wireless head, and UE uses two different component carriers and this two websites to communicate.Under this situation, the required TA of different component carriers is also different.
For above-mentioned these and analogue, embodiment of the present invention component carrier management method and equipment, the same frequency being sent according to UE by eNB or different-frequency measure reporting judge which component carrier is suitably for UE configuration and uses, thereby for UE configures suitable component carrier, reduce unnecessary random access procedure.
As shown in Figure 4, be a kind of flow chart of embodiment of the present invention component carrier management method in eNB side, comprise the following steps:
Described descending timing offset information can be the indication of the descending timing offset of measured component carrier, or the descending timing value of measured component carrier; Described descending timing offset indication is for representing that whether the descending timing value of measured component carrier is identical with the descending timing value of the current one or more component carriers that using of UE.
In order to reduce the impact of measure error, can be in the time that the difference of the descending timing value of the descending timing value of the measured component carrier of UE and the current one or more component carriers that using be no more than a predefined value, the timing value measuring is defined as identical with the timing value using, in the time that described difference exceeds this predefined value, the two is defined as to difference.
In addition, in the time that the descending timing value of one or more component carriers of the current use of UE is multiple different value, UE need in the time reporting descending timing offset indication, indicate to eNB measured component carrier concrete with the current component carrier using in which or multiple component carrier there is descending timing offset.
Such as, when the descending timing value of component carrier of measuring and the difference of the descending timing value of the current one or more component carriers that using of UE are in preset range, and the component carrier of this measurement meets certain signal quality condition, the component carrier of this measurement is defined as to the component carrier increasing, the replacement carrier wave that maybe needs the component carrier removing.
ENB is obtaining after described descending timing offset information, has grasped the timing value of the component carrier of measuring, and the component carrier of this measurement can be defined as to the component carrier of increase or the replacement carrier wave of existing component carrier.Because the Timing Advance of the component carrier of described measurement is grasped by eNB, UE, without carry out random access on this carrier wave, has reduced UE random access procedure effectively, has saved the power consumption of UE.
Certainly how eNB can the comprehensive decision of signal quality based on descending timing offset information and component carrier increase, replaces or delete component carrier, for example, after the descending timing offset information of component carrier of knowing measurement, be defined as the component carrier of increase or the replacement carrier wave of existing component carrier by meeting certain signal quality condition and the carrier wave of descending timing offset in preset range in the component carrier of measurement.
In the time that the traffic carrying capacity of UE increases, eNB need to increase new component carrier for UE, to meet its QoS (Quality of Service, service quality) requirement; Equally, in the time that UE traffic carrying capacity reduces, eNB need to remove unnecessary component carrier for UE, to save system resource and to reduce UE power consumption; In addition, in the time of the component carrier Quality Down of the current use of UE, eNB need to replace the component carrier of current use for UE distributes the good component carrier of new quality, to meet the qos requirement of UE.
Embodiment of the present invention component carrier management method, the descending timing offset information of carrying measured component carrier in the same frequency sending at UE or different-frequency measure reporting, the signal quality of eNB based on this descending timing offset information and component carrier, is defined as the component carrier that described UE increases, removes or replace.Thereby can configure suitable component carrier for UE, reduce the unnecessary random access procedure of UE.
For fear of reporting of unnecessary descending timing value, in embodiments of the present invention, also can be further comprising the steps:
ENB is at broadcast or RRC (Radio Resource Control, Radio Resource control) measure in control message and indicate described UE to report described descending timing offset information, to indicate described UE that described descending timing offset information is carried in described measurement report; Or
ENB indicates under the current eNB of described UE or adjacent eNB and has repeater or RRU in broadcast or RRC measurement control message, to indicate described UE that described descending timing offset information is carried in described measurement report; Or
ENB indicates predefined value of described UE in broadcast or RRC measurement control message, to indicate described UE to differ while exceeding described predefined value at the descending timing value of described component carrier and the descending timing value of the current one or more component carriers that using of UE, described descending timing offset information is carried in described measurement report.
In addition, while switching between different e NB in order to carry out at UE, target eNB can be correctly UE configuration component carrier, in the embodiment of the present invention, also can be further comprising the steps: switch in set-up procedure at described UE, whether the described UE that the described descending timing offset information of carrying in the measurement report that described eNB reports UE and eNB are known supports the ability information of many Timing Advances pattern to be transmitted to target eNB.Correspondingly, whether described target eNB supports the ability information of many Timing Advances pattern according to described descending timing offset information and UE, determines can be the component carrier that described UE distributes.
As shown in Figure 5, be a kind of flow chart of embodiment of the present invention component carrier management method in UE side, comprise the following steps:
Described descending timing offset information can be: the indication of the descending timing offset of corresponding measured component carrier, and/or the descending timing value of measured component carrier; Described descending timing offset indication for the difference that represents the descending timing value of measured component carrier and the descending timing value of the current one or more component carriers that using of UE whether in preset range.Particularly, UE can obtain by the synchronizing signal of measurement component carrier or reference signal the descending timing value of this component carrier.
Mention above, for fear of reporting of unnecessary descending timing value, eNB can measure control message by broadcast or RRC, and whether whether indication UE reports under described descending timing offset information or the indication current eNB of UE or adjacent eNB has repeater or remote radio unit (RRU) or indicate predefined value of described UE.
Correspondingly, in embodiments of the present invention, also can be further comprising the steps:
Receive broadcast or RRC measurement control message that eNB sends;
In control message, indicate UE to report to have repeater or remote radio unit (RRU) under described descending timing offset information or the indication current eNB of UE or adjacent eNB or indicate predefined value of described UE and the descending timing value of component carrier that described UE is measured and the descending timing value of the current one or more component carriers that using of UE differ and exceed described default value, the descending timing offset information of carrying measured component carrier in described measurement report if described broadcast or RRC measure; Otherwise in described measurement report, do not carry the descending timing offset information of measured component carrier.
Due to the mobility of UE, in UE moving process, the position of UE and base station is always changing, and corresponding descending timing offset information just needs to constantly update.Therefore, in embodiments of the present invention, UE also can initiatively send same frequency or the different-frequency measure reporting that carry described descending timing offset information to eNB, whether has increased repeater or RRU equipment to assist eNB to judge in current network.Such as, the changing value of the descending timing value of finding the one or more component carriers in eNB as UE in measuring process within the default time exceeded a threshold value, and UE can be carried at this event information and in measurement report, send to eNB; Further, the positive and negative information reporting that UE can change descending timing offset value in measurement report is to eNB, thereby eNB is being obtained after this information, judge that UE enters or shifted out repeater or RRU equipment overlay area, eNB also can judge in current network, whether to have increased repeater or RRU equipment based on these information.
Embodiment of the present invention component carrier management method, the descending timing offset information of carrying measured component carrier in the same frequency sending at UE or different-frequency measure reporting, thereby can make the signal quality of eNB based on this descending timing offset information and component carrier, be defined as the component carrier that described UE increases, removes or replace, for UE configures suitable component carrier, reduce the unnecessary random access procedure of UE.
Further illustrate for example respectively the message interaction process of UE and eNB in the embodiment of the present invention below.
As shown in Figure 6, be a kind of message interaction process of UE and eNB in the embodiment of the present invention, comprise the following steps:
Step 61.eNB sends indication information by the mode of dedicated signaling or broadcast to UE, and the indication information that specifically can send is following one:
(1) whether indication UE reports the descending timing value of measured component carrier;
(2) whether indication UE reports timing offset indication information to eNB;
(3) under indication UE current eNB, whether there are repeater or RRU, so that the information that UE provides based on this indication determines whether reporting the descending timing value of descending timing offset indication or measured component carrier;
(4) send a preset value to UE, when the descending timing value of the measured component carrier of UE and the descending timing value of the current one or more component carriers that using of UE differ while exceeding certain described predefined value, report descending timing offset to indicate or the descending timing value of measured component carrier to eNB.
This step is optional step, its objective is in order further to avoid reporting of unnecessary descending timing offset information.
Step 62.UE carries out component carrier measurement, measures the descending timing value of one or more component carriers of current service eNB and the descending timing offset absolute value of one or more component carriers of current use is greater than predefined value.
Step 63.UE is in sending with frequency or alien frequencies carrier wave measurement report to eNB, in this measurement report, by the descending timing value of component carrier measured UE whether the indication information identical with the descending timing value of the current one or more component carriers that using be carried at and in measurement report, send to together eNB; Or UE is carried at the descending timing value of measured component carrier in measurement report, to send to together eNB.
Further, when the descending timing value of one or more component carriers of the current use of UE is while being multiple, UE need in the time reporting descending timing offset indication, indicate to eNB measured component carrier concrete with the current one or more component carriers that using in which component carrier there is descending timing offset.
Step 64.eNB is in the time need to configuring new component carrier or replace or remove existing component carrier for UE, descending timing offset information based on carrying in described measurement report and the signal quality of component carrier, for UE configures new component carrier, or replace or remove existing component carrier.
Particularly, can be in the following manner for UE configures corresponding component carrier:
If current UE only supports single TA pattern (being that UE only can use a TA value) simultaneously:
(1) when eNB determines to allow UE use up component carrier corresponding to descending timing value different from current descending timing value, or when the descending component carrier that the descending timing value different from current descending timing value is corresponding and up component carrier, eNB can send corresponding message to UE, this message comprises and is used to indicate the new up component carrier that UE need to use, or new descending component carrier and the information of up component carrier, this message can be switching command message, or PDCCH (Physical Downlink ControlChannel, Physical Downlink Control Channel) command messages, or use MAC (Media AccessControl, media access control) control PDU (Protocol Data Unit, protocol Data Unit) mode send.Alternatively, in these message, can comprise UE and carry out the indication information of uplink synchronous and/or special random access lead code that UE need to use and/or special random access channel resource.
(2) when eNB determines to allow UE use descending component carrier corresponding to descending timing value different from current descending timing value, but while not using the up component carrier of its correspondence, eNB sends corresponding message to UE, can comprise the system information of the descending component carrier of new configuration in this message.Particularly, this message can be the RRC reconfiguration message without mobile management IE; Certainly can be also that the mode that uses MAC to control PDU or physical layer signaling sends.
If current UE supports many TA pattern, whether eNB determines to allow UE carry out uplink synchronous process on new configuration or the new up component carrier activating.
In addition, the descending timing value whether identical indication information of eNB based on carrying in measurement report, but determine whether shift out config set by configuring the component carrier also not activating; Or by the component carrier deexcitation configuring and activated or shift out config set.
As shown in Figure 7, be the another kind of message interaction process of UE and eNB in the embodiment of the present invention, comprise the following steps:
Step 71.eNB sends indication information to UE, concrete identical with step 61 shown in Fig. 6.
The changing value of the descending timing value that step 72.UE finds the one or more component carriers in eNB in measuring process within the time of certain predetermined exceeded a default threshold value.
Step 73.UE is carried at this event information in measurement report, to send to eNB.
Can be descending timing catastrophic event by this event definition that the changing value of descending timing value has exceeded a default threshold value within the time of certain predetermined.
Further, the positive and negative information reporting that UE can be in measurement report changes descending timing offset value is to eNB, thereby eNB can obtained after this information, judges whether UE enters or shifted out repeater or RRU overlay area.
The event information of step 74.eNB based in measurement report, determines whether to remove or deexcitation or replace one or more upstream or downstream component carriers that UE uses.
Step 75.eNB sends RRC to UE and connects reconfiguration message or component carrier deexcitation message (removing or deexcitation part upstream or downstream component carrier).
Particularly, if the changing value of the descending timing value that eNB has received the measured one or more descending component carriers of UE that UE reports within the default time exceeded the event of the threshold value of setting, this event can be referred to as to descending timing value catastrophic event.Certainly, UE also can report this event by measurement report, and described descending timing offset information can also be: descending timing value catastrophic event.In this case, if up component carrier corresponding to the descending component carrier in described catastrophic event in state of activation:
ENB sends synchronous indication information to UE, on the corresponding up component carrier of descending component carrier of indication UE in described catastrophic event, carries out new uplink synchronous process;
Or, eNB uses another up component carrier to replace up component carrier corresponding to descending component carrier in described catastrophic event, and the descending timing value of descending component carrier corresponding to this another up component carrier under current state and the descending component carrier that above-mentioned descending timing value catastrophic event occurs are that descending timing value before descending timing sudden change occurs is identical;
Further, eNB can indicate UE to use the current TA value of safeguarding of UE to new up component carrier, and does not need to carry out uplink synchronous process; The TA value that described current UE is being safeguarded refers to the TA value using on the up component carrier that while there is described descending timing value catastrophic event, the descending component carrier of UE in described catastrophic event is corresponding;
Or eNB indication UE carries out uplink synchronous process on new up component carrier, and indication UE is using current uplink transmission power as the initial gain value of carrying out uplink synchronous process.The current uplink transmission power of described UE refers to the uplink transmission power using on the up component carrier that while there is described descending timing value catastrophic event, the descending component carrier of UE in described catastrophic event is corresponding.
As shown in Figure 8, be the another kind of message interaction process of UE and eNB in the embodiment of the present invention, comprise the following steps:
Step 81.UE carries out component carrier measurement.
Step 82.UE sends measurement report to source eNB, carries the descending timing offset indication information of the component carrier under measured target BS in this measurement report.
Step 83. source eNB sends handover request message to target eNB, carries the descending timing offset indication information of the component carrier under target BS and/or UE and whether support the ability information of many TA pattern in this handover request message.
Whether the descending timing offset indication information of the component carrier under the measured target eNB of UE that step 84. target eNB forwards based on source eNB and UE support the ability information of many TA pattern, determine can be the component carrier of UE distribution.
Step 85. target eNB sends switching request acknowledgement message to source eNB.
Step 86. source eNB receives after this switching request acknowledgement message, sends switching command to UE.
Because UE need to obtain by random access procedure the TA value of up component carrier, therefore, utilize embodiment of the present invention component carrier management method, make eNB configure suitable up component carrier for UE.For example, for the UE that only supports single TA, eNB can distribute the component carrier that can share a TA value for UE, thereby guarantees that UE only needs to carry out one time random access procedure on new one or more component carriers.And for the UE that supports many TA, eNB can be based under described target eNB the descending timing offset indication information of component carrier be that UE configures the component carrier that can share same TA value as far as possible, thereby reduce the number of times that UE needs the random access procedure of carrying out on new component carrier, thereby can effectively avoid unnecessary random access procedure and component carrier layoutprocedure, save UE power consumption.
It should be noted that, the measurement report message described in the embodiment of the present invention also can with other independently or existing message replace.
