Specific embodiment

In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, following will be combined with the drawings in the embodiments of the present invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, shall fall within the protection scope of the present invention.

The embodiment of the present invention provides monitoring, method of sending and receiving and the device of a kind of Downlink Control Information, for solving in current LTE system, different business demand or scene demand are supported simultaneously, the listening mode of existing terminal device will increase terminal device calculation amount, so that terminal device power consumption increase, improve terminal device production cost the problem of.

The scheme of various embodiments of the present invention is applicable to LTE communication system or the evolution row communication system of LTE, in senior long term evolution (Long Term Evolution-Advanced, abbreviation LTE-A) communication system.It is described in detail by taking LTE system as an example below.It include the network equipment and terminal device in LTE system.The network equipment mainly carries DCI by down control channel, sends scheduling information to terminal device.Terminal device is monitored in the search space being made of candidate down control channel and (detects) with the presence or absence of one's own DCI, when detecting one's own DCI, then can be carried out data transmission according to the scheduling information that the data in DCI are transmitted.The process that terminal device detects DCI in the candidate down control channel of search space is known as blind Detecting, and when search space is bigger or the candidate down control channel of fixing search space domestic demand detection is more, blind examination number is more.Wherein, the network equipment and terminal device can be illustratively the equipment such as server, base station, work station, computer, gateway, mobile phone, laptop.

When specific implementation, the search space that terminal device monitors DCI is composed of one or more candidate down control channels, and each candidate's down control channel can be used in carrying DCI.In short, search space is the set of candidate down control channel.Terminal device needs to monitor candidate down control channel, so searching the candidate down control channel set in plain space i.e. terminal device monitoring.Illustratively, search space is made of one or more PDCCH, which is properly termed as PDCCH search space.Illustratively, search space is made of one or more EPDCCH, which is properly termed as the search space EPDCCH.

Search space includes public search space (Common Search Space, abbreviation CSS) and the specific search space of user equipment (UE Specific Search Space, abbreviation UESS) two types.Fig. 2 is the structural schematic diagram of existing search space.As shown in Figure 2, wherein, CSS is the search space that multiple terminal devices will be monitored in cell, it be all users is all shared control channel unit (Control Channel Element, abbreviation CCE) space or shared candidate down control channel set, UESS is the search space that particular terminal device needs to monitor in cell, is space or the set of candidate down control channel of the CCE that terminal device possesses.The UESS of different terminal equipment can be equally or different, for the CSS and UESS of the same terminal device can as and also it is different.Correspondingly, the UESS that PDCCH UESS is made of the PDCCH that Rel-8 is defined, PDCCH CSS are by Rel-8 The CSS, the UESS that EPDCCH UESS is made of the EPDCCH that Rel-11 is defined of the PDCCH composition of definition.In the prior art, CSS is only made of PDCCH, so CSS refers to the CSS of PDCCH in the embodiment of the present invention.

Further, down control channel can be the channel for being used to carry DCI that PDCCH or EPDCCH and future version define.For example, if the channel also regards down control channel as when the channel of carrying DCI is located at the region Physical Downlink Shared Channel (Physical downlink Shared Channel, abbreviation PDSCH).

Various physical channels in existing LTE system are all Transmission Time Interval (Transmission Time Interval, abbreviation TTI) Design of length according to 1ms, i.e. TTI is minimum time unit, also referred to as subframe subframe.A radio frames (radio frame) in LTE system include 10 subframes, and the length of each subframe is 1ms, and each subframe includes two time slots (slot), and each slot is 0.5ms.Each subframe is made of 14 or 12 symbols.Although TTI length is 1ms, the time-domain resource that data transmission occupies can be less than 1ms.For example, preceding 1,2,3 or 4 symbol in a downlink subframe can be used for transmitting PDCCH, but it is not used in transmission PDSCH.Therefore, the time-domain resource that the downlink data transmission that TTI length is 1ms occupies can be less than 1ms.In another example, last 1 symbol in one sub-frame of uplink can be used for transmission channel detection reference signal (Sounding Reference Signal, abbreviation SRS), therefore, the time-domain resource that the transmitting uplink data that TTI length is 1ms occupies might be less that 1ms.TTI length is denoted as short TTI less than the TTI of 1 subframe or 1ms, short TTI data transmission is the TTI length of data transmission less than 1 subframe or 1ms.For example, short TTI length is 0.5ms, 4 symbol lengths, 3 symbol lengths, 2 symbol lengths or 1 symbol lengths.Similarly, the time-domain resource that short TTI data transmission occupies might be less that short TTI length.

In current LTE system, terminal device monitors the DCI that down control channel obtains oneself, after terminal device listens to the DCI of oneself, the reception of downlink data can be carried out according to the instruction information in DCI, and hybrid automatic repeat-request (Hybrid Automatic Repeat reQuest is sent according to the reception result of the downlink data received, abbreviation HARQ) information, the transmission of upstream data can also be carried out according to the instruction information in DCI.DCI is received from terminal device, send HARQ information to terminal device or sends upstream data, terminal device needs certain processing time to carry out data processing, is considered the response time of data transmission this period.Response time make terminal device transmission and the network equipment reception it is with uniformity.The prior art is according to above-mentioned minimum time unit subframe, in advance If the response time is the fixation multiple of 1ms TTI, usually 4ms, i.e. 4 subframe (4 1ms TTI).Fig. 1 is the response time schematic diagram of data transmission in existing LTE system.As shown in Figure 1, the corresponding time interval of 4 1ms TTI receives the downlink subframe where downlink data for terminal device certainly, and downlink subframe where the interval time of sub-frame of uplink or terminal device receive uplink scheduling information where terminal device sends the corresponding HARQ information of the downlink data and terminal device send the interval time of the corresponding upstream data place sub-frame of uplink of the uplink scheduling information.Illustratively, as shown in Figure 1, downlink subframe where terminal device receives the downlink data of network equipment transmission is subframe i-4, and sub-frame of uplink where terminal device sends the corresponding HARQ information of the downlink data is subframe i, and the interval between subframe i-4 and subframe i is time interval.Wherein, i is the positive integer greater than 4.

According to above-mentioned analysis, different business demand or scene demand are matched when existing in system, terminal device needs to monitor the corresponding DCI of multiple business demand in whole search spaces, to cause blind Detecting number excessive, cause to increase terminal device calculation amount, so that terminal device power consumption increase, improve terminal device production cost the problem of.

Specific embodiment is used below, and the transmission, monitoring, method of reseptance of Downlink Control Information provided by the invention are described in detail.

On the one hand the embodiment of the present invention provides the transmission, monitoring, method of reseptance of a kind of Downlink Control Information, wherein the executing subject of sending method is the network equipment, monitors, the executing subject of method of reseptance is terminal device.

Fig. 3 is the signaling process figure of the sending method embodiment one of Downlink Control Information provided in an embodiment of the present invention.Fig. 4 is the signaling process figure of the monitor method embodiment one of Downlink Control Information provided in an embodiment of the present invention.As shown in Figure 3 and Figure 4, this method comprises:

It includes the scheduling information that the data with the first Transmission Time Interval TTI are transmitted that S301, the network equipment send the first Downlink Control Information DCI, the first DCI in public search space CSS.

S302, the network equipment send the 2nd DCI or the 3rd DCI in the dedicated search space UESS of physical downlink control channel PDCCH；2nd DCI includes the scheduling information that the data with the 2nd TTI are transmitted, and the 3rd DCI includes the scheduling information that the data with the 3rd TTI are transmitted.

It includes the scheduling information that the data with the first Transmission Time Interval TTI are transmitted that S401, terminal device monitor the first Downlink Control Information DCI, the first DCI in public search space CSS.

S402, terminal device monitor the 2nd DCI and/or the 3rd DCI in the dedicated search space UESS of physical downlink control channel PDCCH；2nd DCI includes the tune that the data with the 2nd TTI are transmitted Information is spent, the 3rd DCI includes the scheduling information that the data with the 3rd TTI are transmitted.

Specifically, S301 and S302 not stringent sequential relationship, can execute in synchronization, can also execute respectively；S401 and S402 not stringent sequential relationship, can execute in synchronization, can also execute respectively；S301 and S302 can be performed both by, and can also only carry out a step therein, and S401 and S402 are performed both by.It should be noted that the sending step of S301, S302 and the monitoring step of S401, S402 do not have restricting relation, it can be individually separated execution, i.e. S401 and S402 can still be executed when S301 and/or S302 step is not present.

Illustratively, in S301 and S302, the network equipment indicates specific TTI by the DCI that instruction is carried on the candidate down control channel in part searches region, so that terminal device can be according to the different DCI listened to, it determines different TTI, improves the efficiency of data transmission；Simultaneously as whole regions of search are used to indicate different DCI, therefore, the incrementss of the blind examination number of terminal device are smaller.

DCI is used to indicate data transmission, and in other words, DCI is for dispatching data packet, for example, DCI scheduling Physical Uplink Shared Channel (Physical uplink Shared Channel, abbreviation PUSCH) or PDSCH.Optionally, although DCI is used for schedule data transmission, DCI can be served only for the scheduling information rather than trigger data transmission of designation date transmission.Therefore, terminal device needs to monitor the DCI that the network equipment is sent to terminal device before carrying out data transmission.And the down control channel for carrying DCI is a candidate down control channel in search space, so terminal device is it needs to be determined that search space.

Optionally, before step S401, terminal device determines CSS.Before step S401, terminal device determines the UESS of PDCCH.Further, the high-level signaling that terminal device can be sent according to the network equipment, determines the UESS of CSS and/or PDCCH.High-level signaling can be wireless heterogeneous networks (Radio Resource Control, abbreviation RRC) signaling.It should be noted that terminal device determines the not stringent sequential relationship of the UESS of CSS and PDCCH, for example, terminal device can first determine CSS, the UESS of PDCCH is determined again, alternatively, first determining the UESS of PDCCH, CSS is determined again, alternatively, determining the UESS of CSS and PDCCH simultaneously.

First DCI is located at CSS, and the 2nd DCI and the 3rd DCI are located at UESS.First DCI is used to dispatch the data with the first TTI and transmits, and the 2nd DCI is used to dispatch the data with the 2nd TTI and transmits, and the 3rd DCI is used to dispatch the data with the 3rd TTI and transmits.Wherein, the data with the first TTI pass Defeated data transmission with the 2nd TTI and the data transmission with the 3rd TTI are downlink data transmission or transmitting uplink data, or, two of them data are transmitted as downlink data transmission and a data are transmitted as transmitting uplink data, alternatively, two of them data are transmitted as transmitting uplink data and a data are transmitted as downlink data transmission.

Optionally, downlink data transmission mentioned above can be PDSCH transmission perhaps short PDSCH transmission transmitting uplink data can be PUSCH transmission or short PUSCH transmission.Wherein, short PDSCH can be the time-frequency domain resources that data are used for transmission on transmission period, which can be the transmission period less than or equal to 1ms.Short PUSCH can be the time-frequency domain resources that data are used for transmission on transmission period, which can be the transmission period less than or equal to 1ms.

Optionally, the time span of the first TTI and the time span of the 3rd TTI are 1ms, 0.5ms, 4 symbol lengths, 3 symbol lengths, two kinds in 2 symbol lengths and 1 symbol lengths.Wherein, the time span of the first TTI is greater than the time span of the 3rd TTI.For example, the time span of the first TTI is 1 subframe or 1ms, the length of the 3rd TTI is the time span less than 1ms.3rd TTI is short TTI.

Optionally, terminal device monitors DCI, if terminal device listens to cyclic redundancy check (cyclic redundancy check, CRC) correct candidate control channel, then the DCI of candidate control channel carrying is the DCI for schedule data transmission that the network equipment is sent to terminal device.If terminal device does not listen to the correct candidate control channel of CRC, illustrate that the network equipment does not send DCI to terminal device.It should be noted that how the present invention monitors DCI with no restriction to terminal device.For example, terminal device monitors the first DCI in CSS, terminal device can be according to the information bit of the first DCI to candidate's down control channel decodings all or part of in CSS.

Wherein, optionally, if terminal device listens to the DCI for schedule data transmission, can be carried out data transmission according to the DCI with the network equipment.For downlink data transmission, terminal device can receive the downlink data packet that the network equipment is sent on the data transmission resources that DCI is indicated, for transmitting uplink data, terminal device can send upstream data packet to the network equipment on the data transmission resources that DCI is indicated.Optionally, the data transmission resources of DCI instruction are the time-domain resource of data transmission.

Illustratively, the business or scene of terminal device are different, and the DCI that the network equipment is sent to it is different, therefore, the scheduling information that can be transmitted by the data of different DCI instruction terminal equipment.If the response time of terminal device data transmission is different, then the response time that can also be transmitted by the data of different DCI instruction terminal equipment.

In specific implementation, in S401, it includes the scheduling information that the data with the first TTI are transmitted that terminal device monitors the first Downlink Control Information DCI, the first DCI in public search space CSS.Optionally, this DCI is considered the first DCI by the DCI that terminal device listens in CSS, terminal device., optionally, terminal device is monitored in CSS after the first DCI, further includes: terminal device carries out the data with the first TTI according to the first DCI and the network equipment that listen to and transmits, and the data with the first TTI are transmitted as transmitting uplink data or downlink data transmission.

In specific implementation, in S402, terminal device monitors the 2nd DCI and/or the 3rd DCI in the UESS of PDCCH；2nd DCI includes the scheduling information that the data with the 2nd TTI are transmitted, and the 3rd DCI includes the scheduling information that the data with the 3rd TTI are transmitted；Wherein, the time span of the first TTI is greater than the time span of the 3rd TTI, and the time span of the first TTI is equal to the time span of the 2nd TTI.Optionally, terminal device is monitored in the UESS of PDCCH after the 2nd DCI and/or the 3rd DCI, further include: terminal device carries out the data with the 2nd TTI according to the 2nd DCI and the network equipment that listen to and transmits, and/or, terminal device carries out the data with the 3rd TTI according to the 3rd DCI and the network equipment that listen to and transmits, and the data transmission with the 2nd TTI or the data with the 3rd TTI are transmitted as transmitting uplink data or downlink data transmission.

Optionally, if the UESS that terminal device is configured PDCCH before S402 is monitored, terminal device executes S402.

Optionally, if terminal device has the ability of the shortening response time of 1ms TTI or is configured with the shortening response time of 1ms TTI, terminal device monitors the 2nd DCI in the UESS of PDCCH, is otherwise just not listening to the 2nd DCI.Shortening the response time refers to the response time less than 4 subframes, such as response time of 3 subframes or the response time of 2 subframes.

Optionally, if terminal device has the ability of short TTI or is configured with 1 short TTI, terminal device monitors the 3rd DCI in the UESS of PDCCH, is otherwise just not listening to the 3rd DCI.

Since terminal device is when monitoring DCI, it is unclear monitor obtained DCI be the first DCI, it is any or several in the 2nd DCI, the 3rd DCI, only determination is monitored in which search space, therefore, terminal device need to monitor all DCI in all search spaces, the first DCI, the 2nd DCI, the 3rd DCI are monitored i.e. in CCS and UESS.Indicate the DCI of specific TTI since the embodiment of the present invention can make the region of search of part monitor, with it is in the prior art in the DCI that whole TTI is monitored in all regions of search compared with, and reduce blind examination number.

The transmission of Downlink Control Information provided in an embodiment of the present invention, monitor method, the network equipment is in CSS The first DCI of middle transmission sends the 2nd DCI or the 3rd DCI in the UESS of PDCCH.Terminal device monitors the first DCI in CSS, the 2nd DCI and/or the 3rd DCI is monitored in the UESS of PDCCH, and the time span of the first TTI is greater than the time span of the 3rd TTI.By the DCI specific TTI of instruction to be sent by part searches space, so that the blind examination number of terminal device is reduced.

Further, on the basis of the above embodiments, to be further applicable in more business demands and scene, the response time can be indicated by DCI or listens to the search space instruction response time of DCI, so that in the case where not increasing blind Detecting number, the response time of designation date transmission, achieve the purpose that improve data transfer efficiency.It is specific:

The response time that first DCI is used to indicate data transmission was the first response time, the response time that 2nd DCI is used to indicate data transmission was the second response time, the response time that 3rd DCI is used to indicate data transmission is the third response time, and the time span of the first response time is greater than the time span of the second response time.

Illustratively, Fig. 5 is the search space schematic diagram of the transmission of Downlink Control Information provided in an embodiment of the present invention, monitor method embodiment two.As shown in figure 5, terminal device determines the response time according to the search space for listening to DCI.

Optionally, when terminal device listens to DCI in CSS, terminal device thinks that the response time of the corresponding data transmission of this DCI was the first response time.

Optionally, when terminal device listens to DCI in the USS of PDCCH, terminal device thinks that the response time of the corresponding data transmission of this DCI is the second response time or third response time.Further, terminal device determines that the response time is the second response time or third response time according to the instruction information in DCI.Such as have a bit indication information in DCI and represented for the second response time to indicate, 0,1 represents the third response time.Vice versa.

Optionally, the time span of the first response time is greater than the time span of third response time.Such as first the time span of response time be 4 subframes, the time span of the second response time is 3 subframes or 2 subframes, and the time span of third response time is 8 or 12 symbol lengths.

Wherein, response time is terminal device from receiving downlink data place TTI, the interval time of TTI to where sending the corresponding hybrid automatic repeat-request HARQ information of downlink data transmission, or terminal device is from receiving TTI where uplink scheduling information, to the interval time for sending the corresponding upstream data place TTI of uplink scheduling information.It should be understood that TTI where sending the corresponding hybrid automatic repeat-request HARQ information of downlink data transmission is to be when responding the time that TTI where receiving downlink data is delayed Between, or it is the response time that TTI where the corresponding upstream data of transmission uplink scheduling information, which is the time that TTI where receiving uplink scheduling information is delayed,.Here TTI can be subframe, be also possible to several symbols, identical as the time span of the first TTI of front, repeat no more.It should be noted that because the network equipment, which can be shifted to an earlier date or be delayed with instruction terminal equipment, sends uplink information there are propagation delay.Fig. 6 is the schematic diagram of the response time embodiment one of data transmission in LTE system provided in an embodiment of the present invention, as shown in Figure 6, such as there may be misaligned on the uplink boundary of place TTI number 4 and the place TTI number 4 of downlink transfer that sends, at most difference 0.67ms at present, it is assumed that the response time is 4 subframes, it but be in practice time that TTI number 0 where receiving downlink data is delayed from the number 4 for sending TTI where the corresponding hybrid automatic repeat-request HARQ information of downlink data transmission be about (4-0.67) ms is 3.33ms, here being considered as the corresponding time still is 4 TTI or 4 subframes.

The time span of uplink of embodiment of the present invention TTI and the time span of downlink TTI can be identical, can not also be identical.Fig. 7 is the schematic diagram of the response time embodiment two of data transmission in LTE system provided in an embodiment of the present invention, as shown in fig. 7, can define the response time according to Fig.7, when the time span of uplink TTI is identical with the time span of downlink TTI.When the time span of uplink TTI and the time span difference of downlink TTI, then the response time can be the multiple or downlink TTI time span of uplink TTI time span.Optionally, the response time can be the multiple of larger time span in uplink TTI and downlink TTI, or when DCI is indicating downlink data receiver, the response time is the multiple of downlink TTI time span；When DCI is uplink scheduling information, the response time is the multiple of uplink TTI time span.The present invention for response time size and chronomere without limitation.
