Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention is clearly retouched It states, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the present invention In embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts Example, shall fall within the protection scope of the present invention.
The embodiment of the present invention fully takes into account problems of the prior art, is configuring SRS resource and CQI money for UE Behind source, determine that the ON phase in DRX cycle, (hereinafter referred to as DRX activated phase or DRX according to configured SRS resource and CQI resource The ON phase), when finding that the DRX ON phase is greater than tolerance value, one of SRS resource and CQI resource or whole is reconfigured, to shorten DRX ON Phase, in this way, the time that UE enters dormant period increases, power saving effect is promoted.
It should be noted that tolerance value can be set in base station in the form of preset threshold, and the setting of preset threshold It can be carried out according to the demand of operator, the present invention is with no restrictions.
The embodiment of the present invention is described in detail below in conjunction with attached drawing:
Referring to FIG. 2, it is a kind of flow chart of resource allocation method provided in an embodiment of the present invention, as shown in Fig. 2, should Method includes the following steps:
S201, when UE access wireless access network, base station is that UE configures SRS resource and CQI resource.
S202, base station determine the DRX ON phase of UE, i.e. ON in DRX cycle according to the SRS resource and CQI resource of configuration Phase.
The determining DRX ON phase is compared by S203, base station with preset threshold.
S204, if it is determined that the DRX ON phase be greater than preset threshold, then base station be UE be reconfigured SRS resource and/or CQI resource with Shorten the DRX ON phase.
The information of the resource of reconfiguration is sent to UE by S205, base station.
When the resource being reconfigured in step S204 is SRS resource, the information of the resource of reconfiguration includes the SRS resource of reconfiguration Information；When the resource being reconfigured in step S204 is CQI resource, the information of the resource of reconfiguration includes the letter of the CQI resource of reconfiguration Breath；When SRS resource had not only been reconfigured in step S204 but also CQI resource has been reconfigured, then the information for the resource being reconfigured includes the SRS of reconfiguration The information of the resource of the CQI of the information and reconfiguration of resource.
As it can be seen that above method after configuring SRS resource and CQI resource for UE, can check according to the SRS resource of configuration and Whether the DRX ON phase that CQI resource determines is greater than preset threshold, and when being greater than preset threshold, SRS resource and/or CQI is reconfigured Resource elongates the dormant period in DRX cycle to shorten the DRX ON phase, and power saving effect is promoted.
It should be noted that A and/or B in the present embodiment and following embodiment, refer to one of A and B or whole, example In above step 204, base station is that SRS resource and/or CQI resource is reconfigured in UE, refers to that base station is UE reconfiguration SRS resource, or CQI resource, or reconfiguration SRS resource and CQI resource is reconfigured.In above step S205, if SRS money has only been reconfigured in base station Source, then the information of the SRS resource after reconfiguration can be sent to UE by base station, naturally it is also possible to after reconfiguration, by SRS resource Information and the information of CQI resource be sent to UE together, the information of the CQI resource after being reconfigured at this time and the resource before reconfiguration are believed Breath is the same, therefore can not also send.If CQI resource has only been reconfigured in base station, base station can be by the CQI resource after reconfiguration Information is sent to UE, naturally it is also possible to after reconfiguration, the information of the information of CQI resource and SRS resource is sent to UE together, The information of SRS resource after being reconfigured at this time can not also be sent as the resource information before reconfiguration.If base station pair SRS resource and CQI resource are all reconfigured, then base station all sends out the information of the information of the SRS resource after reconfiguration and CQI resource Give UE.
In above step S201, base station can pass through wireless heterogeneous networks (Radio Resource Control, RRC) Connecting establishment process is that UE configures SRS resource and CQI resource.For example, referring to FIG. 3, it establishes signaling flow for a kind of RRC connection Figure.As shown in figure 3, UE, can when accessing wireless access network for long term evolution (Long Term Evolution, LTE) Request (RRC Connection Setup Request) message is established to send RRC connection to base station, base station is receiving it RRC connection just, which is returned, to UE afterwards establishes (RRC Connection Setup) message, the RRC Connection Setup message Middle carry is the information for the SRS resource that UE is configured and the information of CQI resource, and the information of SRS resource and the information of CQI resource include Base station is that the report cycle and time-domain position of the SRS and CQI of UE configuration indicate information, in order to which UE subsequent can be reported in the ON phase When use.
In above step S201, base station may include time-domain position for the UE process for configuring SRS resource and CQI resource The configuration of configuration and report cycle.To which in above step S201, base station is that UE configuration SRS resource includes configuring reporting for SRS The time-domain position in period and SRS；Base station is that UE configuration CQI resource includes the time-domain position for configuring the report cycle and CQI of CQI. And base station is that UE configuration SRS resource can index (srs-ConfigIndex) Lai Shixian by configuring the configuration of SRS, base station is UE configuration CQI resource can index (cqi-pmi-ConfigIndex) Lai Shixian by configuring the configuration of CQI.At this point, base station is sent out The information for giving the information of the resource of the SRS of UE and the resource of CQI can be srs-ConfigIndex and cqi-pmi- ConfigIndex.The side UE can store srs-ConfigIndex corresponding period and time-domain position table and cqi-pmi- ConfigIndex corresponding period and time-domain position table.In this way, UE receives the srs-ConfigIndex and cqi- of base station transmission After pmi-ConfigIndex, can according to the two above period of storage and time-domain position table inquiry SRS report cycle and The report cycle and time-domain position of time-domain position and CQI, and according to inquiry gained, report SRS and CQI.
Wherein, reporting for SRS is timing purpose in order to meet UE, and CQI is calculated for reporting channel quality to base station Signal-to-noise ratio, be scheduled for using.
Base station is after UE has configured SRS resource and CQI resource, above step S202 can be executed, for example, base station is matched for UE After having set SRS resource and CQI resource, it can be provided when starting the DRX function of UE according to configured SRS resource and CQI Source calculate the DRX ON phase, the calculating about the DRX ON phase be one of skill in the art will understand that, details are not described herein.Base It stands after calculating the DRX ON phase, above step S203 can be executed, i.e., be compared the DRX ON phase with preset threshold.Before It has been already mentioned that this preset threshold is the tolerance value that operator can tolerate, can be set according to the demand of operator, no It is limited.Since ON phase proportion is smaller, dormant period proportion is higher, then UE gets over power saving, therefore, can be pre- by here If threshold value is set as 2 subframes, a subframe is for sending SRS, and a subframe is for sending CQI, that is to say, that ON time phase is long Degree is 2 subframes.It is greater than preset threshold when the ON phase that base station is calculated, then base station needs that SRS resource and/or CQI is reconfigured for UE Resource is to shorten the DRX ON phase, for example, can be less than according to the ON phase of SRS resource and CQI Resource Calculation out after reconfiguration Or it is equal to preset threshold.Then by after reconfiguration SRS resource and/or CQI resource be sent to UE so that UE using reconfiguration after SRS resource and/or CQI resource report SRS and/or CQI to base station.Here preset threshold is not limited to 2 subframes, can also be with For other values, here without limitation.In addition, small according to the ON phase of SRS resource and CQI Resource Calculation out after reconfiguration about making In or be equal to preset threshold, the effect that this refers to reach, it is practical realize in can be realized by finding the means of resource, and The DRX ON phase after not needing real computing resource reconfiguration；It is of course also possible to further calculate confirmation, the present invention is with no restrictions.
Furthermore, it is possible to by after reconfiguration SRS resource and/or the carrying of CQI resource set in message and be sent in RRC connection reconfiguration UE.Base station after having configured SRS resource and CQI resource (after may include the good SRS resource of initial configuration and CQI resource, such as After above step S201；Also may include reconfiguration SRS resource and/or CQI resource after, such as after above step S204), The DRX function that process starts UE can be set in RRC connection reconfiguration.For example, with continued reference to FIG. 4, it is a kind of RRC connection reconfiguration Confidence enables flow graph.The DRX ON phase is calculated according to configured SRS resource and CQI resource, is then set in RRC connection reconfiguration DRX relevant parameter is sent to UE, including DRX cycle and DRX in (RRC Connection ReConfigration) message The ON phase.In addition, above step S205, that is, send the information process of the resource of reconfiguration, it can also be during RRC connection reconfiguration be set Complete, for example, carry in RRC Connection ReConfigration message reconfiguration srs-ConfigIndex and/or The cqi-pmi-ConfigIndex of reconfiguration.In this way, base station reports the DRX ON phase of SRS and CQI to be just controlled in tolerance Interior, for example, 2 subframes, so that resource is distributed rationally, DRX ON time phase shortens, and time dormant period is elongated, and reaches for UE Power saving effect is arrived.
The time-domain position of SRS or CQI is reconfigured in above embodiments, so that the DRX ON phase shortens, realizes UE's Power saving.In addition, in the prior art it has been already mentioned that the period of DRX is usually longer, and the report cycle of SRS and CQI is in existing skill Setting is tended not in art so to grow, especially when being less than or equal to DRX cycle for 2 times of the report cycle of SRS or CQI, one Multiple SRS or CQI can be reported in a DRX cycle.This frequently can lead to secondary or more the time for reporting SRS or CQI Dormant period in DRX cycle, it not will do it report at this time, but base station has been that UE is configured with resource, and cannot It is allocated to other UE to use, leads to the wasting of resources.Therefore, the report cycle of SRS or CQI can further be reconfigured, so that UE is adopted Give the correct time with the report cycle of SRS or CQI after reconfiguration, a SRS or CQI is only reported in a DRX cycle, with section Save interface-free resources.If 2 times of the report cycle of SRS and CQI are both less than or are equal to DRX cycle, can be by the upper of SRS or CQI The report period is all reconfigured.
At this point, the above reconstitution process may include period reconfiguration and time-domain position reconfiguration.As it can be seen that base station is that SRS is reconfigured in UE The process of resource may include: the time-domain position that SRS is reconfigured；Alternatively, the report cycle of reconfiguration SRS；Alternatively, reconfiguration SRS when The report cycle of domain position and SRS.Base station is that the process that CQI resource is reconfigured in UE may include: the time-domain position that CQI is reconfigured；Or The report cycle of CQI is reconfigured in person；Alternatively, the time-domain position of reconfiguration CQI and the report cycle of CQI.
Be reconfigured about the period: 2 times when the SRS report cycle that base station is UE configuration are less than or equal to DRX cycle, reconfiguration SRS report cycle, so that 2 times of the SRS report cycle after reconfiguration are greater than DRX cycle.Preferably, can be by SRS report cycle Reconfiguration is DRX cycle.2 times when the CQI report cycle that base station is UE configuration are less than or equal to DRX cycle, and reconfiguration CQI reports week Phase, so that 2 times of the CQI report cycle after reconfiguration are greater than DRX cycle.Preferably, CQI report cycle can be reconfigured as DRX Period.
When being less than or equal to DRX cycle for 2 times of SRS report cycle and/or the report cycle of CQI, a DRX cycle Multiple SRS or CQI can be reported, in addition, base station can be reported multiple SRS and/or CQI in DRX cycle due to UE and be UE distributes extra resource, but UE does not report SRS and CQI other than the DRX ON phase, i.e., dormant period do not report SRS and Therefore CQI results in waste of resources, and cannot give extra resource distribution to other UE.In general, UE reports one in the DRX ON phase Secondary SRS and/or CQI can be met the requirements, if the report cycle of SRS and CQI is reconfigured to it is identical as DRX cycle, can be with Guarantee the resource for only once reporting SRS and CQI in a DRX cycle, the local resource that base station is UE distribution can be saved, Guarantee that base station is not necessarily UE and distributes extra resource.
It is reconfigured about time-domain position: currently, the configuration process of SRS resource and CQI resource independently carries out, and this implementation In example, during time-domain position reconfiguration, the configuration of SRS resource and CQI resource is no longer independently carried out.For example, ought be only When the time-domain position of SRS resource is reconfigured, the time-domain position of configured CQI resource can be referred to；When CQI resource is only reconfigured When the position of domain, the time-domain position of configured SRS resource can be referred to；When the time-domain position that SRS resource is not only reconfigured, but also reconfiguration It when the time-domain position of CQI resource, can carry out simultaneously, choose resource as similar as possible and distribute to SRS and CQI simultaneously, for example, It configures adjacent subframe and is used for transmission SRS and CQI.So that the SRS resource and CQI resource after reconfiguration further on time-domain position, Shorten the DRX ON phase.
For example, during resource is reconfigured, it can first be subject to SRS current time zone position, if in the left and right of SRS two Suitable CQI resource can be found for the UE in a subframe, then by the resource distribution found to CQI；If not finding suitable money Source, then be subject to CQI current time zone position, if can find suitable SRS money for the UE in the subframe of the left and right of CQI two Source, then by the resource distribution found to SRS；If all not finding suitable resource by both the above mode, then find simultaneously It can be reconfigured and close on the resource at time point to two of the SRS and CQI of UE, and the resource found is reconfigured to UE.This is only One simple realization example, is not intended to limit the present invention, the sequence of three above step is adjustable, does not do any limit System.In addition it is also possible to be reconfigured using other way, such as finds resource as similar as possible in the time domain and provided as SRS Source and CQI resource, and calculate and these resources were reconfigured to the DRX ON phase after UE, if DRX ON expires, foot is expected, by this A little resources are reconfigured as SRS resource and CQI resource to UE.DRX ON described here expires sufficient expection can be default by being arranged Value realizes that this preset value can be identical as above-described preset threshold, might be less that above-described preset threshold. And if the calculated DRX ON phase is less than or equal to preset value, the SRS resource and CQI resource of reconfiguration can be used as.
As it can be seen that in the embodiment above, base station be UE configure SRS resource include configure SRS report cycle and SRS when Domain position, and can be realized by configuring srs-ConfigIndex；Base station is that UE configuration CQI resource includes that configuration CQI reports week Phase and CQI time-domain position, and can be realized by configuring cqi-pmi-ConfigIndex.Likewise, base station is that SRS is reconfigured in UE Resource includes the time-domain position that the report cycle and SRS of SRS is reconfigured, and can be realized by reconfiguration srs-ConfigIndex；Base Standing and CQI resource is reconfigured for UE includes reconfiguration CQI report cycle and CQI time-domain position, and can pass through reconfiguration cqi-pmi- ConfigIndex is realized.And the above period reconfiguration and time-domain position reconfiguration can be realized simultaneously, that is, pass through reconfiguration srs- ConfigIndex and/or cqi-pmi-ConfigIndex is realized.
In addition, base station to the information of the resource of the UE reconfiguration sent may include reconfiguration srs-ConfigIndex and/or The cqi-pmi-ConfigIndex of reconfiguration.Then, UE reports the time-domain position of SRS and CQI and period that can pass through srs- The two parameters of ConfigIndex and cqi-pmi-ConfigIndex obtain.
It is 40ms with DRX cycle, in UE access wireless access network, base station is that the srs-ConfigIndex of UE configuration is For 17, cqi-pmi-ConfigIndex be 26.And following table 1 and table 2 is combined to be illustrated, wherein Tables 1 and 2 is respectively Srs-ConfigIndex corresponding period and time-domain position table and cqi-pmi-ConfigIndex corresponding period and time domain Position table.The two tables can store in UE, in order to which UE is in the parameter srs-ConfigIndex for receiving base station and issuing When with cqi-pmi-ConfigIndex, week is reported according to the two parameter queries SRS report cycle and time-domain position and CQI Phase and time-domain position.When srs-ConfigIndex is 17, for inquiry table 1 it is found that SRS report cycle is 20ms, SRS time domain is inclined It is set to 17-17, i.e., 0, at this point, it is the 0th work song frame that SRS, which reports time-domain position,.When cqi-pmi-ConfigIndex is 26, look into For inquiry table 2 it is found that CQI report cycle is also 20ms, CQI time domain is biased to 26-17, i.e., 9, and it is the 9th that CQI, which reports time-domain position, at this time Work song frame.As it can be seen that SRS is differed farther out with the time-domain position that CQI is reported, the DRX ON phase has been elongated；In addition, SRS's and CQI reports 2 times of period are equal to DRX cycle.Therefore, at this time, it may be necessary to carry out time-domain position reconfiguration to one of SRS and CQI or whole, and it is right The period of SRS and CQI is reconfigured.Wherein, during being reconfigured in the period, the report cycle of SRS and CQI can be reconfigured It is reduced resource waste for 40ms, the i.e. period of DRX so that UE only reports a SRS and CQI in a DRX cycle.Meanwhile If not only having sent SRS in the DRX ON phase but also having sent CQI, it includes the 0th work song frame to the 9th work song frame that the DRX ON phase is needed before reconfiguration This 10 subframe lengths, have elongated the ON phase, and UE is caused to enter the reduction of time dormant period in such a scenario, and power saving effect is bad, In this way, when time-domain position is reconfigured, it, can be by CQI time-domain position if the 1st subframe free time of the adjacent position of SRS time-domain position Reconfiguration is the 1st subframe, and at this moment, according to table 1, srs-ConfigIndex parameter reconfiguration is 37, cqi-pmi-ConfigIndex Parameter reconfiguration is 38.Alternatively, if adjacent the 8th subframe or the 11st subframe free time of CQI time-domain position, it can also be by SRS Time-domain position reconfiguration be the 8th subframe or the 11st subframe.If both the above mode is all without appropriate resources, Ke Yiwei Two resources for closing on time point are reconfigured in SRS and CQI, such as idle closing on is the 0th subframe and the 3rd subframe.

Referring to FIG. 5, a kind of flow chart of its resource allocation method provided for further embodiment of this invention, such as Fig. 5 institute Show, this method comprises the following steps:
S501: when UE access wireless access network, base station is that UE configures SRS resource and CQI resource.
For example, base station is just according to normal after UE sends RRC connection request message request access wireless access network to base station Resource distribution process be the independent configuration SRS resource of UE and CQI resource, then the information of configured resource is sent to UE, the information of resource here may include the period given the correct time on SRS and CQI and the information of time-domain position, such as the resource of SRS Information can be srs-ConfigIndex, the information of the resource of CQI can be cqi-pmi-ConfigIndex.
S502: base station determines the report cycle of SRS and the report cycle of CQI according to the SRS resource and CQI resource of configuration.
For example, after UE establishes RRC with base station and connect, authenticated in UE and base station, service negotiation during, base Standing-meeting starts the DRX function of UE, and the DRX ON phase of UE is calculated according to configured SRS resource and CQI resource.
S503: when being less than or equal to DRX cycle for 2 times of the report cycle of determining SRS, base station reconfiguration SRS's is reported Period, so that 2 times of the report cycle of the SRS after reconfiguration are greater than DRX cycle；And/or
S504: when being less than or equal to DRX cycle for 2 times of the report cycle of determining CQI, base station reconfiguration CQI's is reported Period, so that 2 times of the report cycle of the CQI after reconfiguration are greater than DRX cycle.
Above step S503 and S504 can pass through reconfiguration srs-ConfigIndex and cqi-pmi- respectively ConfigIndex is realized.
S505: base station by after reconfiguration SRS resource information and/or CQI resource information be sent to UE.
For example, the srs-ConfigIndex of reconfiguration and/or cqi-pmi-ConfigIndex are sent to UE.
In a preferable implementation, in above step S503, the report cycle of SRS can be reconfigured is DRX weeks Phase the report cycle of CQI can be reconfigured in above step S504 as DRX cycle.
In addition, the time-domain position of SRS resource can also be reconfigured while the period of SRS is reconfigured；Likewise, being reconfigured While the period of CQI, the time-domain position of CQI resource can also be reconfigured.The same above embodiments of reconfiguration about time-domain position, This is repeated no more.
It describes to match by the resource for configuring srs-ConfigIndex and cqi-pmi-ConfigIndex with reference to the accompanying drawing Method is set, referring to FIG. 6, a kind of flow chart of its resource allocation method provided for further embodiment of this invention, such as Fig. 6 institute Show, this method comprises the following steps:
S601: when UE access wireless access network, base station is that UE configures srs-ConfigIndex and cqi-pmi- ConfigIndex。
S602: base station determines the DRX of UE according to the srs-ConfigIndex and cqi-pmi-ConfigIndex of configuration The ON phase.
S603: the determining DRX ON phase is compared by base station with preset threshold.
S604: when the determining DRX ON phase be greater than preset threshold when, base station be UE be reconfigured srs-ConfigIndex and/or Cqi-pmi-ConfigIndex is to shorten the DRX ON phase.
S605: base station by after reconfiguration srs-ConfigIndex and/or cqi-pmi-ConfigIndex be sent to UE.
Preferably, in above step S604, if 2 times when the SRS report cycle that base station is UE configuration are less than or wait In DRX cycle, when srs-ConfigIndex is reconfigured, need to consider to be determined according to the srs-ConfigIndex after reconfiguration The report cycle of SRS needs to meet preset condition, that is, 2 times for meeting the report cycle of the SRS after reconfiguration are greater than DRX cycle, example It is such as DRX cycle according to the report cycle of the SRS determined of the srs-ConfigIndex after reconfiguration.Equally, if when base station is UE 2 times of the CQI report cycle of configuration are less than or equal to DRX cycle and need to consider basis when srs-ConfigIndex is reconfigured The report cycle for the CQI that srs-ConfigIndex after reconfiguration is determined needs to meet preset condition, that is, meets the CQI after reconfiguration 2 times of report cycle be greater than DRX cycle, such as the report cycle according to the CQI determined of the srs-ConfigIndex after reconfiguration For DRX cycle.
In above each embodiment, base station can carry out resource reconfiguration for part UE, can also for all UE into Row, but carried out for all UE, the overall performance of system may be will affect.If this is because base station distribute always SRS and The time-domain position of CQI is many very close to the distribution limitation of, two kinds of resources, and it is excessive to will lead to fragment in system resource allocation, influence be The performance for entirety of uniting, in order to minimize the energy consumption of UE under the behavior pattern for not influencing system entirety.Some can be set Part allows base station to carry out resource reconfiguration to part UE, realizes resource optimization.
For example, base station is that the condition that UE is reconfigured is greater than in advance in addition to setting when the DRX ON phase during resource optimization If except threshold value, can also indicate that base station carries out resource optimization to part UE by some cells.For example, allowing part UE to base station Instruction information is sent, base station only starts the deterministic process of resource reconfiguration to the UE for having sent instruction information, that is, judges DRX Whether the ON phase is greater than the process of preset threshold.
Therefore, with continued reference to FIG. 7, the flow chart of its resource allocation method provided for further embodiment of this invention.Such as In addition to each step described by the above embodiments shown in Fig. 7, further includes: receive the energy conservation instruction information that UE is sent, the energy conservation It is that one of SRS resource and CQI resource or complete is reconfigured in UE when the DRX ON phase being greater than preset threshold that instruction information, which is used to indicate base station, Portion.The step can be transmitted to base station in UE access wireless access network, can also be after UE access wireless access network It carries out, for example, sending energy conservation instruction information from UE to base station after UE access wireless access network.It is indicated when receiving the energy conservation After information, DRX ON phase and preset threshold are compared in base station again.
S701, when UE access wireless access network, base station is that UE configures SRS resource and CQI resource.
S702, base station determine the DRX ON phase of UE according to the SRS resource and CQI resource of configuration.
S703, when the energy conservation instruction information of UE transmission has been received in base station, base station is by determining DRX ON phase and pre- If threshold value is compared.
S704, if it is determined that the DRX ON phase be greater than preset threshold, then base station is that SRS resource and/or CQI resource is reconfigured in UE.
The information of the resource of reconfiguration is sent to UE by S705, base station.
The above energy conservation instruction information can be a newly-increased cell, can be carried by existing message；Or it is new The message of increasing, directly sends base station by UE；In addition it is also possible to be realized using existing cell.Illustratively, for supporting For the UE of R11 agreement, which can use existing user equipment and assists message (UE Assistance Information battery capacity indication (power PrefIndication) cell entrained by) is realized, in this way, can not modify Existing protocol reduces the waste of interface-free resources without increasing cell.The state of the power PrefIndication cell can be with There are two types of, respectively normal (normal) state and energy saving (low Power Consumption) state.If UE is sent out to base station UE Assistance Information is sent, wherein carrying power PrefIndication cell and power PrefIndication is power save mode, then shows that the request base station UE is done power saving for UE itself and distributed rationally.When base station receives this Cell can compare DRX ON phase and preset threshold, and the starting reconfiguration process when the DRX ON phase is more than preset threshold.
In addition, having no ability to propose for power saving requirement (such as the UE for not supporting R11 agreement) for UE, when cell SRS and CQI resource is unrestricted, for example, local resource is sufficient, when to can satisfy the DRX ON phase be 2 subframes, inside of base station can be with SRS the and CQI time-domain position of which UE distribution is periodically checked down apart from farther out, such as the DRX ON phase calculated has been greater than 10 The thresholding of a subframe, so that it may SRS or CQI resource be reconfigured for these UE automatically, to optimize resource, promote power saving effect；Alternatively, When SRS the and CQI resource of cell is relatively limited, that is, when resource is unable to satisfy the case where being 2 subframes DRX ON phase, base station The DRX ON phase can be made to be not limited to 2 subframes for the resource of UE reconfiguration, for example, preset value may be 3 or 4 subframes In the case of, it also can be better than the power saving effect of 10 subframes etc, as long as can shortening DRX ON phase as far as possible, so that it may be saved for UE Electricity promotes whole power saving effect.
Referring to FIG. 8, it is the method for information reporting under a kind of discontinuous reception DRX state provided in an embodiment of the present invention Flow chart, as shown in figure 8, this method comprises the following steps:
S801:UE sends wireless access request message to base station.
S802:UE receives the response message that base station is sent, and response message includes the detection reference signal that base station is UE configuration The information of SRS resource and the information of channel quality indicator (CQI) resource.
S803: when the DRX of the UE activation phase being greater than preset threshold, UE receives the reallocation message that base station is sent, reallocation message Information including the resource that base station is UE reconfiguration, the resource of reconfiguration include the SRS resource of reconfiguration and one of the CQI resource of reconfiguration or All.
S804:UE determines report cycle and time-domain position according to the information of the resource of reconfiguration, determining report cycle and when Domain position includes the report cycle and time-domain position of one of SRS and CQI or whole.
For S805:UE according to determining report cycle and time-domain position, Xiang Jizhan reports one of SRS and CQI or whole.
In above step S801, the wireless access request message that UE is sent can establish request (RRC for RRC connection Connection Setup Request) message, upon receipt, just the response into UE return step S802 disappears for base station Breath can establish (RRC Connection Setup) response message for RRC connection, that is to say, that base station can connect by RRC It connects in establishment process and configures SRS resource and CQI resource for UE connection.Carry in the RRC Connection Setup message is UE The information of the SRS resource of configuration and the information of CQI resource, the information of SRS resource and the information of CQI resource include that base station is matched for UE The report cycle and time-domain position of the SRS and CQI that set indicate information, in order to which UE subsequent can give the correct time use on the ON phase.This In base station be UE configure SRS resource can by configure SRS configuration index (srs-ConfigIndex) Lai Shixian, base station (cqi-pmi-ConfigIndex) Lai Shixian can be indexed by configuring the configuration of CQI by configuring CQI resource for UE.At this point, base station The information for being sent to the information of the resource of the SRS of UE and the resource of CQI can be srs-ConfigIndex and cqi-pmi- ConfigIndex.UE can be according to the srs-ConfigIndex corresponding period of storage and time-domain position table and cqi-pmi- ConfigIndex corresponding period and time-domain position table inquire SRS's according to the two above period of storage and time-domain position table The report cycle and time-domain position of report cycle and time-domain position and CQI, and according to inquiry gained, Xiang Jizhan report SRS and CQI。
It, can be when starting the DRX function of UE, according to having matched after base station is that UE has configured SRS resource and CQI resource The SRS resource and CQI resource set calculate the DRX ON phase, the DRX ON phase are compared with preset threshold, as shared by the ON phase Ratio is smaller, and dormant period proportion is higher, then UE gets over power saving, therefore, preset threshold here can be set as to 2 subframes, One subframe is for sending SRS, and a subframe is for sending CQI, that is to say, that ON phase time span is 2 subframes.Work as base station The ON phase calculated is greater than preset threshold, then base station needs for UE reconfiguration SRS resource and/or CQI resource to shorten the DRX ON phase, For example, can be less than or equal to preset threshold according to the ON phase of SRS resource and CQI Resource Calculation out after reconfiguration, then, Above step S803 can be executed, i.e., when the DRX of the UE activation phase being greater than preset threshold, UE receives the reconfiguration that base station is sent and disappears Breath, reallocation message include the information for the resource that base station is UE reconfiguration, and the resource of reconfiguration includes the SRS resource and reconfiguration of reconfiguration One of CQI resource is whole.Here reallocation message can set (RRC Connection for RRC connection reconfiguration ReConfigration) message.
At this point, the process being reconfigured above may include period reconfiguration and time-domain position reconfiguration.As it can be seen that base station is UE reconfiguration The process of SRS resource may include: the time-domain position that SRS is reconfigured；Alternatively, the report cycle of reconfiguration SRS；Alternatively, reconfiguration SRS The report cycle of time-domain position and SRS.Base station is that the process that CQI resource is reconfigured in UE may include: the time-domain position that CQI is reconfigured； Alternatively, the report cycle of reconfiguration CQI；Alternatively, the time-domain position of reconfiguration CQI and the report cycle of CQI.Wherein, base station can lead to It crosses reconfiguration srs-ConfigIndex and is embodied as the report cycle of UE reconfiguration SRS and the time-domain position of SRS, by the way that cqi- is reconfigured Pmi-ConfigIndex is embodied as UE reconfiguration CQI report cycle and CQI time-domain position.Namely UE receives the reconfiguration that base station is sent Message includes one of srs-ConfigIndex and cqi-pmi-ConfigIndex after reconfiguration or whole.
Then, above step S804 is executed, UE determines report cycle and time-domain position according to the information of the resource of reconfiguration, really Fixed report cycle and time-domain position includes the report cycle and time-domain position of one of SRS and CQI or whole.When execution, UE can With according to storage srs-ConfigIndex corresponding period and time-domain position table and cqi-pmi-ConfigIndex it is corresponding Period and time-domain position table, according to the report cycle of the SRS after the two above period of storage and the inquiry reconfiguration of time-domain position table And the report cycle and time-domain position of time-domain position and CQI.
After UE has determined one of SRS resource and CQI resource after reconfiguration or whole, step S805 is executed, i.e. UE is according to really Fixed report cycle and time-domain position, Xiang Jizhan report one of SRS and CQI or whole, certainly, if base station is only for UE reconfiguration SRS resource, then UE can report SRS to base station according to the SRS resource after reconfiguration, since CQI resource does not carry out weight Match, UE just reports CQI to base station according to the CQI resource configured before；If base station is only that CQI resource has been reconfigured for UE, UE can report CQI to base station according to the CQI resource after reconfiguration, and since SRS resource is not reconfigured, UE is just according to before The SRS resource of configuration reports SRS to base station；If base station is that SRS resource and CQI resource has been reconfigured in UE, UE is just according to weight SRS resource and CQI resource after matching report SRS and CQI to base station.
In the above-described embodiments, be also possible to part UE obtained base station resource reconfiguration, be also possible to all UE all into It has gone resource reconfiguration, but has been carried out for all UE, the overall performance of system may have been will affect, if this is because base station Always the time-domain position of SRS and CQI is distributed very close to there are many two kinds of resources distribution limitation, will lead to broken in system resource allocation Piece is excessive, influences the performance of system entirety, in order to minimize the energy consumption of UE under the behavior pattern for not influencing system entirety. Some conditions can be set, allows part UE to obtain the resource reconfiguration process of base station, realizes resource optimization.For example, in resource optimization In the process, UE obtains base station and carries out the condition of resource reconfiguration in addition to setting other than the DRX ON phase is greater than preset threshold, can be with Indicate that base station carries out resource optimization to part UE by some cells.For example, part UE sends energy conservation instruction information, section to base station Can indicate information be used to indicate base station DRX activation the phase be greater than preset threshold when for UE be reconfigured one of SRS resource and CQI resource or All, that is, make deterministic process of the base station only to the UE starting resource reconfiguration for having sent instruction information, that is, judge DRX Whether the ON phase is greater than the process of preset threshold.
Wherein, energy conservation instruction information can be a newly-increased cell, can be carried by existing message；Or Newly-increased message, directly sends base station by UE；In addition it is also possible to be realized using existing cell.Illustratively, for supporting For the UE of R11 agreement, which can use existing user equipment and assists battery capacity indication entrained by message Power PrefIndication cell is realized, in this way, existing protocol can not modify, without increasing cell, reduction is eated dishes without rice or wine The waste of resource.The state of the power PrefIndication cell can there are two types of, respectively normal (normal) state With energy saving (low Power Consumption) state.If UE has sent UE Assistance to base station Information, wherein carrying power PrefIndication cell and power PrefIndication as energy saving shape State then shows that the request base station UE is done power saving for UE itself and distributed rationally.When base station receives the cell, the DRX ON phase can be compared With preset threshold, and the DRX ON phase be more than preset threshold when starting reconfiguration process.
