The every other embodiment that logical technical staff is obtained under not making creative work premise,
Broadly fall into the scope of protection of the invention.
As it is shown in figure 1, The embodiment provides a kind of method obtaining schedule information,
Based on UE, comprise the steps:
S11, determines used blind Detecting pattern；
S12, uses described blind Detecting pattern to carry out the blind Detecting of CSS to obtain schedule information；When
When described blind Detecting pattern is normal mode, multiple subframes to be detected are all carried out the blind check of CSS
Survey；When described blind Detecting pattern is battery saving mode, only to specific in multiple subframes to be detected
Subframe carries out the blind Detecting of CSS.
After using technique scheme, the method for the acquisition schedule information that the embodiment of the present invention provides,
The blind Detecting of different mode can be used the blind check of CSS is carried out according to the difference of application scenarios
Survey, when using the blind Detecting of normal mode, each subframe all carried out the blind Detecting of CSS,
When using battery saving mode, only specific subframe is carried out the blind Detecting of CSS.So, UE is just
Need not each subframe be carried out the blind Detecting of CSS always, effectively reduce the average of UE
Blind Detecting number of times, effectively reduces the average power consumption of UE.
It should be noted that the schedule information that UE sends to obtain base station needs to carry out subframe
DSS and CSS blind Detecting, in the embodiment of the present invention, to the mode of the blind Detecting that DSS is carried out not
Limit, can be same as the prior art, here is omitted.
And the method for the acquisition schedule information that the embodiment of the present invention provides carries out CSS's to subframe
Blind Detecting includes both of which, i.e. normal mode and battery saving mode.Described normal mode refers to that UE exists
When performing the blind Detecting of DSS, always it is by the blind Detecting of CSS；Described power saving blind mode refers to
UE, when performing the blind Detecting of DSS, optionally performs blind to CSS in specific subframe
Detection.
Optionally, in step s 11, the blind Detecting of an acquiescence can be preset in UE
Pattern, UE can preset according to this and determine used blind Detecting pattern.Such as at this
In a bright embodiment, UE is arranged by the parameter inquiring about self knows that this UE pre-sets
The blind Detecting pattern of acquiescence be normal mode, then UE preset according to this most right
Subframe carries out the blind Detecting of CSS.
Optionally, UE can also receive base station send blind Detecting mode configuration message, and according to

Another embodiment in, UE receive base station send blind Detecting mode configuration message, this blind check
Surveying mode configuration message instruction UE uses battery saving mode that CSS carries out blind Detecting, then UE according to
This blind Detecting mode configuration message carries out the blind Detecting of CSS with battery saving mode to subframe.
It should be noted that in the embodiment of the present invention, the blind Detecting mode configuration message that UE receives
Being the concept of a broad sense, its concrete form can have multiple, both can be UE receive be
System message, it is also possible to the specific messages between the base station received for UE and this UE.
Wherein, when the specific messages that blind Detecting mode configuration message is between base station and UE, this is special
Can also have multiple with the concrete form of message.Such as, in one embodiment of the invention,
When UE needs to carry out data transmission with base station, UE sets up RRC firstly the need of with base station
(Radio Resource Control, wireless heterogeneous networks) connects, then blind Detecting pattern configurations disappears
Breath can be carried on and be received by UE in RRC connection establishment message.Or, when blind Detecting mould
When formula needs to reconfigure, blind Detecting mode configuration message can also be carried on RRC connection and heavily join
Put in message and received by UE.Certainly, blind Detecting mode configuration message can also be that base station sends
The blind Detecting pattern indicating to obtain schedule information for UE it is specifically designed to the one of UE
Message, this message can be a RRC information, MAC (Medium Access Control,
Medium education) message, it is also possible to being a physical layer signaling, the embodiment of the present invention is to this
Do not limit.
Concrete, under the blind Detecting of normal mode, multiple subframes to be detected are all carried out CSS
Blind Detecting, it may include each subframe under continuous reception state is all carried out the blind Detecting of CSS
Or DRX (Discontinuous Reception, discontinuous reception) is in the cycle in activationary time
Each subframe all carries out the blind Detecting of CSS.
It should be noted that described continuous reception refers to that UE monitors PDCCH always；Described DRX
Refer to that UE is not to monitor PDCCH the most continuously, but suspend within a period of time and monitor
PDCCH.Optionally, DRX can be periodic, by eNB (evolved Node Base,
Evolved base station) it is the UE configuration discontinuous cycle monitoring PDCCH.This cycle specifically can wrap
Include activationary time and inactivation time.In the activationary time of DRX cycle, UE needs often
Individual subframe carries out the blind Detecting of PDCCH, and in the inactivation time of DRX cycle, UE
PDCCH channel can not be carried out blind Detecting.The UE that the present embodiments relate to and base station it
Between communication in, UE both can receive, in the way of continuously reception, the information that base station sends, it is possible to
With the information receiving base station transmission with DRX or alternate manner, this is not done by the embodiment of the present invention
Limit.
And in a power-save mode, the embodiment of the present invention according to the schedule information of UE in CSS
Whether occur, can be different for different subframes, according to specific rule, to different subframes
Can select to carry out or do not carry out the blind Detecting of CSS, or carry out different CSS blind Detecting, i.e.
Subframe specific in the most multiple subframes to be detected is carried out the blind Detecting of CSS.
Such as, in one embodiment of the invention, UE can determine whether to carry out at random
Access procedure；If it is required, then UE can be at the accidental access response message of random access procedure
The reception window time in, use RA-RNTI (Random Access-Radio Network
Temporary Identity, random access radio network temporary mark) PDCCH is carried out CSS
Blind Detecting, to obtain the schedule information of described accidental access response message；If it is not needed,
UE does not carries out CSS blind Detecting to this subframe.Thus can reduce the blindest to subframe of UE
Detection number of times, reduces the average power consumption of UE to a certain extent.
Optionally, in another embodiment of the present invention, UE can be according to whether perform
The re-transmission of the message 3 of random access procedure determines the need for using interim C-RNTI (Cell
-RNTI, Cell Radio Network Temporary Identifier/Identity, Cell-RNTI) before random accessing message 3 is successfully transferred to eNB
Carry out the blind Detecting of CSS, to obtain the re-transmission of accidental access response message 3 on PDCCH
The schedule information of resource.
Optionally, in another embodiment of the present invention, UE can also be according to the mark of oneself
What symbol calculating determined needs to use P-RNTI (Paging-RNTI, pager wireless net network temporary mark)
The time of the schedule information of acquisition beep-page message, blind Detecting CSS space within the time calculated,
To obtain the schedule information of beep-page message on PDCCH；
Optionally, in another embodiment of the present invention, UE can also be according to whether connect
Receive system information determine use SI-RNTI (System Information-RNTI, system information without
Line Network Temporary Identifier) obtain time of schedule information of system information, obtain at the needs determined
Blind Detecting CSS space in the time of the schedule information taking system information, to obtain on PDCCH
Take the schedule information of beep-page message.
Additionally, when UE needs to send data to base station, UE need to use great power to
It is also to need to be determined by the power contorl parameters in schedule information that base station sends data.UE can
To know the concrete moment self needing to send data to base station in advance, and blind before this moment
In detection shift time, specific subframe is carried out blind Detecting and sends to described base station to obtain UE
Power contorl parameters information during data, thus control UE and send the power of data to base station.And
In addition to described blind Detecting shift time At All Other Times in, UE the most not to described specifically
Other subframes beyond subframe carry out blind Detecting, the most also can reduce the average blind Detecting time of UE
Number, effectively reduces the average power consumption of UE.Wherein, blind Detecting shift time typically zero or
The minimum transfer time interval of UE.
Concrete, in the data transmission that UE and base station are carried out, a lot of data are periodic uplink transmissions numbers
According to, such as SPS (semi-persistence scheduling, semi-persistent scheduling) data, SRS
(Sounding Reference signaling visits logical reference signal) and CSI (Channel State
Information, channel condition information).And UE and base station are as the sender of data or connect
Debit is clear and definite to delivery time or the cycle of these periodic uplink transmissions data, therefore, and UE
The delivery time of periodic uplink transmissions data can be determined with this.
Concrete, described blind Detecting shift time, refer to that UE sends a section before data to base station
Time, its duration is less than the data transmitting period of above-mentioned periodic uplink transmissions data.UE is possible not only to
Determine described blind Detecting shift time, and can be at the delivery time of these periodic uplink transmissions data
The blind Detecting of CSS is carried out, to obtain power contorl parameters letter in blind Detecting shift time before
Breath.
Illustrating, in one embodiment of the invention, the data transfer cycle of SPS data is
20ms, i.e. UE are at moment 5ms, 25ms, 45ms ... transmit SPS data to base station.For
UE can be made to obtain the base station schedule information for data transmission procedure with less average power consumption,
Preferably, UE does not carry out the blind Detecting of CSS to each subframe, and only transmits in these data
In blind Detecting shift time before cycle arriving, specific subframe is carried out blind Detecting.Such as, UE
Can to described base station send data moment before described blind Detecting shift time in, as
In 1ms, subframe is carried out the blind Detecting of CSS.That is, UE is at 4ms to 5ms, 24ms
To 25ms, 44ms to 45ms ... the interior blind Detecting that subframe is carried out CSS.
It should be noted that although above-described embodiment illustrates with periodic uplink transmissions data instance,
But for acyclic upstream data, UE can also know this upstream data otherwise
Concrete delivery time and corresponding blind Detecting shift time, the present invention is without limitation.
In another embodiment of the present invention, described blind Detecting shift time can also be described
Under nearest at least one of delivery time described in distance before periodic uplink transmissions data delivery time
Time corresponding to row subframe, then UE can also described periodic uplink transmissions data delivery time it
The time corresponding at least one descending sub frame that delivery time described in front distance is nearest, at CSS
Carry out DCI (Downlink Control Information, Downlink Control Information) form 3/3A
Blind Detecting, with obtain power control schedule information.Such as, UE its needs known are sent out to base station
Send the moment of data, such as the delivery time of upstream data, be the 5th subframe, then UE can be
4 subframes, i.e. apart from the nearest descending sub frame of described delivery time, carry out DCI at CSS
The blind Detecting of form 3/3A, to obtain power control schedule information.Certainly, UE can also be
3rd subframe and the 4th subframe, i.e. apart from nearest two descending sub frames of described delivery time,
CSS carries out the blind Detecting of DCI format 3/3A, to obtain power control schedule information.
Optionally, UE can determine described blind Detecting shift time according to presetting, it is also possible to
Notice according to base station determines described blind Detecting shift time.Wherein, the notice of base station includes base
The dedicated signaling of the broadcast stood or base station and UE.
When UE knows described blind Detecting shift time according to the dedicated signaling of base station, described blind check
Survey shift time can be carried on and be received by UE in other dedicated signaling.Such as, optionally,
When can increase blind Detecting skew in the configuration information of original SPS data or SRS or CSI
Between parameter, then UE can obtain by receiving the configuration information of SPS data or SRS or CSI
Know described blind Detecting shift time.Or, in one embodiment of the invention, UE can also
By receiving PUSCH TPC-RNTI (the Transmit Power Control that base station sends
RNTI, transmission power control-Radio Network Temporary Identifier) configuration information know described blind Detecting
Shift time.Optionally, in another embodiment of the present invention, UE can also be by receiving
(Physical Uplink Control Channel, physical uplink shares letter to the PUCCH that base station sends
Road) configuration information of TPC-RNTI knows described blind Detecting shift time.Certainly, blind Detecting is inclined
Shift time can also be sent to UE with the form of a special message by base station, and the present invention is to this
It is not restricted.
Further, in order to enable UE to change blind Detecting pattern, after step S12, this
The method of the acquisition schedule information of bright offer also includes:
Receive the blind Detecting pattern reconfiguration message that base station sends；
Blind Detecting pattern reconfiguration message according to described reception, determines the blind Detecting after reconfiguring
Pattern；
The blind Detecting of CSS is carried out to obtain scheduling letter according to the blind Detecting pattern after described reconfiguring
Breath.
So, UE just can be after determining blind Detecting pattern, the blind check sent according to base station
Survey pattern reconfiguration message switches the blind Detecting pattern used, and reaches to use more flexibly
The purpose of current optimal blind Detecting pattern, blind when need not each subframe is carried out CSS
During detection, can use battery saving mode that specific subframe carries out the blind Detecting of CSS, thus
To a certain extent, the average power consumption of UE is reduced.
Optionally, before receiving the blind Detecting pattern reconfiguration message that base station sends, UE also may be used
To send blind Detecting mode switch request to base station, so that described base station is according to described blind Detecting mould
Formula handover request carries out reconfiguring of blind Detecting pattern.
Optionally, UE can also to base station send battery level information so that described base station according to
Described battery level information carries out reconfiguring of blind Detecting pattern.
Such as, in one embodiment of the invention, determine that its battery electric quantity is pre-less than one as UE
During the threshold value first set, UE just sends blind Detecting mode switch request to base station, so that base station energy
Enough blind Detecting mode switch request sent according to UE generate blind Detecting mode configuration message.When
So, the battery level information of self directly can also be sent to base station, so that base station can by UE
Battery level information according to UE determines whether the blind Detecting pattern of UE is switched to power saving blind check
Survey pattern.Specifically, UE can be at interval of the time of regulation to the electricity letter of base station transmission self
Breath, it is also possible to when the battery electric quantity of UE is less than certain threshold value, sends the electricity of self to base station
Amount information, it is also possible to set up when RRC is connected to base station transmission UE's self with base station at UE
Information about power.The present invention is without limitation.
Accordingly, as in figure 2 it is shown, the embodiment of the present invention also provides for a kind of schedule information of obtaining
Control method, based on base station, specifically includes following steps:
S21, determines the blind Detecting pattern that UE is used；
S22, according to described blind Detecting pattern, sends blind Detecting mode configuration message to described UE,
Described blind Detecting mode configuration message is used for indicating described blind Detecting pattern.
Wherein, when blind Detecting pattern is normal mode, described UE is equal to multiple subframes to be detected
Carry out the blind Detecting of CSS；When blind Detecting pattern is battery saving mode, described UE is only to multiple
In subframe to be detected, specific subframe carries out the blind Detecting of CSS.
After using technique scheme, the control of the acquisition schedule information that the embodiment of the present invention provides
Method, it is possible to indicate UE to use the blind Detecting of different mode to carry out according to the difference of application scenarios
The blind Detecting of CSS.When UE needs that each subframe is carried out blind Detecting, instruction UE uses
Normal mode carries out CSS blind Detecting；When UE is without carrying out blind Detecting to each subframe,
Instruction UE uses battery saving mode, i.e. according to specific rule, only specific subframe is carried out CSS
Blind Detecting, effectively to obtain the schedule information needed for UE.So, UE just can be made to need not
Each subframe is carried out the blind Detecting of CSS always, therefore effectively reduces UE for subframe
Average blind Detecting number of times, effectively reduce the average power consumption of UE.
Concrete, the described blind Detecting that each subframe all carries out CSS can include receiving continuously
Each subframe or discontinuous receiving cycle in each subframe in activationary time all carry out blind check
Survey.
It should be noted that base station is to become to data volume and the transmission frequency of UE transmission schedule information
Change, when base station to send that the data volume of schedule information is big to UE, transmission frequency height time, due to
PDCCH capacity is limited it is possible to make this schedule information not send in time, i.e. creates
The obstruction of PDCCH channel.According to PDCCH blocking probability, base station can determine that UE is used
Blind Detecting pattern.When PDCCH blocking probability is higher than threshold value set in advance, base station needs
The schedule information of UE is deposited in the probability being sent to UE in CSS the highest with regard to comparing, now, base
Station determines the blind Detecting pattern that UE is used, all UE in the community of instruction base station service or
Part UE carries out blind Detecting to subframe in the normal mode；When PDCCH blocking probability less than or etc.
When threshold value set in advance, base station needs to be put in CSS the schedule information of UE to be sent to
The probability of UE just ratio is relatively low, and now, base station determines the blind Detecting pattern that UE is used, instruction
All UE or part UE in the community of base station service carry out CSS with battery saving mode to subframe
Blind Detecting, simultaneously for the UE of the blind Detecting pattern that can use power saving that base station determines, base
Stand and the schedule information of this part UE will not be placed in CSS transmission, thus ensureing UE
While correct acquisition schedule information, effectively reduce the average blind Detecting number of times of UE, effectively drop
The low average power consumption of UE.
Optionally, base station can also determine according to the quantity of the UE activated in the community of base station service
The blind Detecting pattern that UE is used.When the quantity of the UE activated in the community of base station service is more than
During threshold value set in advance, base station needs the schedule information of UE is placed on the probability that CSS sends
The highest, now, base station determines the blind Detecting pattern that UE is used, the service of instruction base station
All UE or part UE in community carry out blind Detecting to subframe in the normal mode；When base station takes
When the quantity of the UE activated in the community of business is less than or equal to threshold value set in advance, base station needs
The probability just ratio that the schedule information of UE is placed on CSS transmission is relatively low, and now, base station determines UE
The blind Detecting pattern used, instruction base station service community in all UE or part UE with
Battery saving mode carries out blind Detecting to subframe, thus effectively reduces the UE average blind check for subframe
Survey number of times, effectively reduce the average power consumption of UE.
Concrete, in one embodiment of the invention, base station instruction UE sends data to base station
Power contorl parameters information also by PDCCH to UE send.Base station can be to described UE
Send blind Detecting shift time notification message, so that described UE is according to described blind Detecting shift time
Notification message determines blind Detecting shift time.
Optionally, base station can send blind Detecting by broadcast or dedicated signaling to described UE
Shift time notification message, so that the described blind check that described UE is before sending data to described base station
Obtain described UE in surveying shift time and send the power contorl parameters information of data to described base station.
Further, after step s 22, the acquisition schedule information that the embodiment of the present invention provides
Control method also include:
Send blind Detecting pattern reconfiguration message to described UE, reconfigure so that described UE uses
Blind Detecting pattern, obtain schedule information.
So, base station can change according to the current intelligence of the UE in Serving cell, sends out to UE
The blind Detecting pattern reconfiguration message sent is so that UE switches the blind Detecting pattern used, and reaching can
To use the purpose of current optimal blind Detecting pattern more flexibly.Particularly right when need not
When each subframe carries out CSS blind Detecting, may indicate that UE uses battery saving mode to specifically
Subframe carries out the blind Detecting of CSS, thus to a certain extent, reduces the average power consumption of UE.
Optionally, before sending blind Detecting pattern reconfiguration message to described UE, base station can connect
Receive the blind Detecting mode switch request that described UE sends；Please according to the switching of described blind Detecting pattern
Ask, determine that the blind Detecting pattern being used described UE reconfigures.
Optionally, base station can also receive battery electric quantity letter that described UE sends, described UE
Breath；According to the battery level information of described UE, determine the blind Detecting mould that described UE is used
Formula reconfigures.
Such as, in one embodiment of the invention, when UE is to the electricity letter of base station transmission UE
During breath, according to the information about power that UE sends, base station can determine that whether this electricity is less than presetting
Threshold value, determine that the blind Detecting pattern being used described UE reconfigures.Such as, if
This electricity is less than described threshold value set in advance, then the blind Detecting pattern used described UE is entered
Row reconfigures, and instruction UE uses battery saving mode to carry out the blind Detecting of CSS.
Below by specific embodiment, offer of the present invention is obtained the method for schedule information and obtains
The control method taking schedule information is described in detail.
