To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.

" data " specifically described herein refer to the transmission block of business datum such as physical layer, and it, which is different from control signaling and other, is used for the signaling or information that indicate such as in the down control channel or Downlink Control Information of physical layer.The embodiment of the present invention is directed to during small data transmission, the problem of efficiency of transmission is low caused by signaling consumption is excessive, UE provided in an embodiment of the present invention, base station and data transmission method can be used for reducing the expense of DCI indication signalings in upstream or downstream transmitting procedure.

The business datum of the present invention is presented as that transmission block is transmitted by physical channel in physical layer, and it can be data channel or is transmitted using the form of control channel.Without loss of generality, the present invention is transmitted to illustrate using data channel PDSCH (can also be enhanced PDSCH).

Predefined described in the embodiment of the present invention can be Default Value, or can for communication both sides, such as base station and UE, between the mode arranged in advance；Configuration described in the embodiment of the present invention can be to be configured by base station, or, it can also be that base station and UE are respectively configured by other network operation instruments, can also be configured by receiving the configuration information of base station in UE lateral roots according to configuration information.

For part small data business, such as M2M (device-to-devices, Mac ne to Madiine, broad sense may also be understood to be equipment to people, Machine to Man, people to equipment, Man to Machine, machine is to mobile phone Machine to Mobile) etc. application, business is more stable in longer period of time, is embodied in physical layer（PHY can be) to use relatively-stationary TBS to be transmitted within a period of time. Relatively-stationary TBS can be predefined or configured and obtain.When needing different TBS switchings, DCI signalings, such as DCI format 1A can be used, TBS instructions are carried out, for example, can indicate the size of the TBS after current or switching.When UE obtains data channel, such as physical down link sharing channel (Physical Downlink Shared Channel, abbreviation：PDSCH), corresponding TBS, can be according to predefined or configuration aggregation level（Aggregation level) PDSCH is detected.When PDSCH position and/or aggregation level do not obtain indicating, UE needs blind Detecting PDSCH.Therefore when signaling does not indicate PDSCH position and/or aggregation level, UE needs blind Detecting PDSCH.When signaling indicates PDSCH position and aggregation level, UE can indicate to carry out PDSCH detection according to signaling, and detection here can be CRC（Cyclic Redundancy Check, referred to as：CRC), whether correctly judge whether PDSDH detects success according to CRC check.Detection subframes of the UE in time domain can be obtained according to predefined or configuration.The subframe of the time domain can be configured according to discontinuous reception DRX cycle or the DRX of extension cycle.

Fig. 1 is the structural representation of UE embodiments one of the present invention, as shown in figure 1, the UE of the present embodiment can include：Determining module 101 and receiving module 102, wherein,

Determining module 101, for determining transport block size TBS;

The determining module 101, is additionally operable to determine transmitting physical DSCH Downlink Shared Channel PDSCH time-domain resource and frequency resource, and the PDSCH is used to transmit the transmission block；

Receiving module 102, for receiving the transmission block in the time-domain resource, frequency resource.The UE of the present embodiment, can be used for blind Detecting PDSCH, it is of course also possible to according to Downlink Control Information (Downlink Control Information, abbreviation：DCI instruction) is detected.When the mode only with blind Detecting receives the data on PDSCH, it is not necessary to DCI instruction.

When UE receives the mode of the data on PDSCH by the way of blind Detecting, the TBS for being preferably adapted for data can be with existing DCI signalings scene of different sizes, but the TBS of data can also apply this mode when identical with the size of existing DCI signalings, and the embodiment of the present invention is not limited this.

The UE of the present embodiment, after determining transport block size TBS, the time-domain resource for transmitting PDSCH, frequency resource in determining module, receiving module is in the time-domain resource, frequency resource, receive the transmission block, therefore, it is possible to realize the blind Detecting to PDSCH, so as to receive downlink data in the case where not needing DCI instruction, therefore, it is possible to reduce control signaling expense, so as to improve system Efficiency of transmission.

The information that carrying out PDSCH blind Detecting or configuration PDSCH blind Detectings needs has：TBS, frequency domain resource, time-domain resource, separately below for these it needs to be determined that information, be described in detail.

Alternatively, the UE of above-described embodiment it is determined that data TBS when, TBS can be default, or the mode signaled according to base station determines that accordingly, the determining module 101 specifically can be used for：The size for determining the transmission block is default TBS;Or,

Wherein, predefined TBS can be that one or more can be the subset of existing TBS forms or the TBS newly increased.When predefining multiple TBS, base station, which can be used, signals which TBS progress blind Detecting instruction UE uses.

When TBS, which is limited, is less than or equal to 1000 bit, the TBS cited by following form can be used when being multiplexed existing TBS values:

The more stable UE of ordinary business practice, such as MTC UE, it is within considerable time, and TBS is relatively fixed.Therefore, base station can signal new TBS when TBS changes by the first TBS for signaling this time by first.Limited TBS value can be predefined for this, which TBS value is then signaled currently employed with first is.Defined limited TBS value can be the subset of existing TBS forms, such as { 208,600,872,1000 }.Used first signaling can be RRC signaling or DCI format or MAC CE or any combination between them.For example, base station can use RRC signaling to indicate, while indicating to carry the PDSCH of the RRC signaling using DCI format such as format 1A.

Further, the determining module 101 can be also used for：

It is determined that transmitting the code rate of the PDSCH；

The receiving module 102, specifically can be used in the time-domain resource, frequency resource, according to The code rate of the PDSCH receives the transmission block.

Wherein, the code rate of the PDSCH can include the aggregation level of the resource granularity of the PDSCH.

Therefore, for the determination of code rate, the determining module 101 specifically can be used for：It is determined that transmitting the aggregation level of the resource granularity of the PDSCH.

This is due to that the polymerization of the resource granularity that PDSCH is made up of one or one group of identical resource granularity unit is transmitted.The polymerization of resource granularity represents that such as aggregation level is 1, then transmits PDSCH by 1 resource granularity using aggregation level;Aggregation level is 2, then transmits PDSCH by 2 resource granularities.

Further, the determining module 101 specifically can be used for：

Wherein, the aggregation level of transmission PDSCH resource granularity includes：The subset of transmitting physical downlink channel control PDCCH resource granularity CCE or the enhanced Physical Downlink Control Channel EPDCCH of transmission resource granularity ECCE aggregation level, or, transmission PDSCH aggregation level comprises at least aggregation level 6.

Wherein, the resource granularity includes the multiple of any one following resource granularity or any one following resource granularity： CCE、 ECCE, REG、 EREG、 PRB、 VRB .

Alternatively, for the determination of frequency domain resource, there can be two ways：

In the first implementation, frequency domain resource can use resource block（Resource block, referred to as：

RB) indicate, or, it can also be indicated with Physical Resource Block PRB (Physical Resource Block) or virtual resource blocks VRB (Virtual Resource Block).Hereinafter it is described by taking RB as an example.The determining module 101 specifically can be used for：

Receive the second signaling that base station is sent, and the configured information determination transmission in second signaling

PDSCH resource block RB, second signaling for it is following at least one：RRC signaling, PDCCH, EPDCCH or MAC CE signalings.

In second of implementation, frequency domain resource is indicated with the mode of bandwidth and original position, this mode be particularly suitable for use in frequency domain resource be continuous resource scene.The determining module 101 specifically can be used for： PDSCH bandwidth is determined according to the configuration of base station；

Further, determining module 101 can determine a larger frequency domain resource scope in above two implementation, when implementing, and UE can also be made to determine that a less scope is detected in the range of above-mentioned larger frequency domain resource.Therefore, the determining module 101 specifically can be also used for：

The second original position of monitoring PDSCH frequency resource is determined according to default hash function.For example, UE first receives frequency resource scope one big according to first way, such as：Numbering is 6,7,8,9,10,11,12,13 RB, then the second original position is determined according to the 4th signaling or hash function, blind Detecting is proceeded by from the second original position, however, it is determined that the second original position is RB 7, then UE can be detected since RB 7 until RB 13.

Alternatively, can be by way of signaling or predefined mode is determined for transmitting the time-domain resource of the PDSCH, therefore the determining module 101 specifically can be used for：

Receive the 5th signaling that base station is sent, and configured information in the 5th signaling determines that transmission PDSCH time-domain resource is the first subframe, the 5th signaling for it is following at least one：RRC signaling, PDCCH, EPDCCH or MAC CE signalings；Or,

The subframe for determining the PDSCH is default first subframe.

When implementing, discrete reception time can be configured（Discontinuous Reception, referred to as：DRX) it is used for PDSCH transmission.Fig. 2 is the structural representation of the PDSCH transmission subframe of discontinuous reception, as shown in Fig. 2 UE carries out PDSCH detection in some sections of discrete time intervals.Activity times of the UE in each DRX cycle in Fig. 2（On duration) carry out PDSCH blind Detecting.Correspondingly, the configured information in the 5th signaling can also include beginning subframe, the activity time of discontinuous receiving cycle and discontinuous reception, and the activity time includes detection active time（On duration timer) corresponding time and/or non-active timer（Inactivity timer) the corresponding time.

Further, the configured information in the 5th signaling also can indicate that：It is the subframe in the activity time for transmitting PDSCH the first subframe. Fig. 3 is the structural representation of UE embodiments two of the present invention, as shown in figure 3, the UE of the present embodiment can also include：Sending module 103, the sending module 103 can be used for after the receiving module is properly received the PDSCH, and confirmation message ACK is sent to base station;Or, after the determining module determines that the PDSCH can not be received, non-acknowledgement message NACK is sent to base station.

So, when base station side receives NACK, or when not receiving ACK time more than certain thresholding, base station can determine that UE not successfully receives the PDSCH, therefore, it can resend.UE (or can repeat the transmission block that sends within default or configuration time to sending the PDSCH for repeating to receive after NACK）Merge.PDSCH repeatedly (or repeat the transmission block of transmission）Or new PDSCH (or the transmission block newly sent）Can be by being made a distinction in the CRC scramblers scrambled.The scrambler can be default or be configured by base station.Or coverage enhancement pattern can be started, continuous p subframe can for example be configured and send same PDSCH, p is integer, coverage enhancement is carried out with accumulation energy, UE can then be detected according to configuration according to continuous p subframe to PDSCH, to improve the success rate of data receiver.

Fig. 4 is the structural representation of UE embodiments three of the present invention, as shown in figure 4, the UE of the present embodiment can also include：Monitor module 104, for the search space that is configured in base station and or the very first time of base station configuration in, monitoring control channel and or PDSCH.Wherein control channel includes PDCCH or E-PDDCH.

The UE of the present embodiment, can be in UE dedicated search space or in certain section of very first time（Or space and the very first time are specified search for simultaneously）Control channel is listened only to, or listens only to PDSCH, or while listening for control channel and PDSCH.Corresponding transmission means can include following several：In UE dedicated search space（Time is not limited）Only transmit control channel；In UE dedicated search space（Time is not limited）Only transmit PDSCH;In UE dedicated search space（Time is not limited）Simultaneous transmission control channel and PDSCH;Within certain section of very first time（Frequency domain is not limited）Only transmit PDSCH;Within certain section of very first time（Frequency domain is not limited）Only transmit PDSCH;In certain section of very first time（Frequency domain is not limited）Simultaneous transmission control channel and PDSCH;PDSCH is transmitted in UE dedicated search space and only in certain section of very first time;Control channel is transmitted in UE dedicated search space and only in certain section of very first time；In UE dedicated search space and in certain section of very first time simultaneous transmission PDSCH and control channel.Wherein, the very first time can such as start for predefined or configuration a period of time positioned at the discontinuous reception time cycle a subframe or several subframes.Fig. 5 be within the specific very first time monitoring control channel and or PDSCH Schematic diagram, as shown in figure 5, control channel and PDSCH are monitored interior at the same time sometimes, do not monitored at the same time sometimes.

Wherein, the search space can be configured by base station or to be default, it is that the very first time can be configured by base station or to be default.

When control channel and PDSCH are not transmitted within the same very first time, blind Detecting number of times can be reduced, UE power consumption is saved.

Further, it can also limit：When the monitoring module 104 monitoring control channel and during PDSCH within the different very first times respectively, the time interval of the very first time of the monitoring control channel or cycle are more than or less than time interval or the cycle for the very first time for monitoring PDSCH.If the time interval of the very first time of monitoring control channel or cycle are more than time interval or the cycle for the very first time for monitoring PDSCH, be conducive to saving signaling consumption；If the time interval of the very first time of monitoring control channel or cycle are less than time interval or the cycle for the very first time for monitoring PDSCH, be conducive to being quickly switched into the other TBS switchings of signaling scheduling pattern progress or hybrid automatic repeat-request（Hybrid-ARQ, referred to as：) or coverage enhancement transmission mode etc. HARQ.

Further, in one implementation, the monitoring module 104 specifically can be used for：The search space that is configured in base station and or the time of base station configuration configuration in monitoring control channel and during PDSCH, control channel and PDSCH are distinguished by the size TBS of transmission block, or, at least one in resource granularity, time-domain position, the frequency domain position distinguishes control channel and PDSCH, or, control channel and PDSCH are distinguished according to default first configured information.

When the signaling of transport block size and existing control channel is of different sizes, PDSCH or control channel can directly be distinguished by TBS.Wherein, the DCI format that the DCI of control channel carrying is used can be existing DCI format subset or whole.The transport block size that the value that can such as predefine only with DCI format 1A, TBS is not equal to DCI format 1A size is considered PDSCH in transmission.

When transport block size is identical with existing DCI format sizes, can be polymerize by using the resource granularity different from DCI format different running time-frequency resource positions or clearly indicate distinguished.

In another implementation, it is described monitor the scrambler that can be scrambled according to cyclic redundancy check (CRC) of module 104 distinguish Downlink Control Information DCI and PDSCH or, the first configured information in the indicating bit or original bit increased newly in the DCI distinguishes control channel and PDSCH.

Activity time, which represents UE, needs blind Detecting PDSCH time.Its time that can at least include on duration timer operations or the time of inactivity timer operations.The time of Inactivity timer operations represents that UE receives the time for needing then continuously to be detected after PDSCH, when UE is not detected by PDSCH and when the time value for having exceeded configuration in the timer time value, UE enters the DRX cycles, or when UE receives a MAC signaling for configuring DRX, U E enter DRX cycle.Except long period, can optionally there is short DRX cycle.Now UE can be introduced into the short cycle, do not receive PDSCH within the short cycle and enter back into long DRX cycle.

Further, for UE, successfully whether blind check measures PDSCH, can be confirmed in the following manner.A kind of is that n+k subframes of the UE after PDSCH subframe is detected is confirmed to base station transmission ACK, if base station does not receive ACK confirmations in preset time, can continue to send PDSCH, for example, be transmitted in n+k+m subframes, also, now PDSCH is transmitted with the aggregation level of lower code check or higher.PDSCH repeatedly (or repeat the transmission block of transmission）Or new PDSCH (or the transmission block newly sent）Can be by being made a distinction in the CRC scramblers scrambled.The scrambler can be default or be configured by base station.If the time for not receiving ACK exceedes certain thresholding, base station can also start coverage enhancement pattern, for example, continuous p subframe can be configured and send same PDSCH, coverage enhancement is carried out with accumulation energy, UE is detected according to configuration according to continuous p subframe to PDSCH, to improve the success rate of data receiver.Wherein n, k, m, p are integer.

For UE, after the UE receives the transmission block in the time-domain resource, frequency resource, according to the code rate, it can also include：

Accordingly for base station, after sending the transmission block to UE in the time-domain resource, frequency resource in the base station, in addition to：

Above-mentioned data transmission method embodiment three and its various implementation describe and transmit downlink data by the way of blind Detecting PDSCH, in following implementation, UE is supported to return back to the instruction according to control channel within specific search space and or the specific very first time to receive PDSCH mode.

Specifically, the base station can default search space and or the default very first time in, to the UE send control channel and or PDSCH.Wherein control channel includes PDDCH and E-PDDCH.

Accordingly, the UE is configured in base station search space and or the very first time of base station configuration in, monitoring control channel and or PDSCH.

Further, it can also limit：When base station sends control channel and PDSCH within the different very first times respectively, the time interval of the time interval of the very first time of the transmission control channel or cycle more than or less than the very first time for sending PDSCH or cycle.When being more than time interval or the cycle for the very first time for sending PDSCH in the time interval of the very first time of the transmission control channel or cycle, be conducive to saving signaling consumption；When being less than time interval or the cycle for the very first time for sending PDSCH in the time interval of the very first time of the transmission control channel or cycle, be conducive to being quickly switched into the other TBS switchings of signaling scheduling pattern progress or HARQ or coverage enhancement transmission mode etc..

Further, in one implementation, when the base station default search space and or the default very first time in, when sending control channel and PDSCH to the UE, also include default first configured information in the control channel or the PDSCH, for making the UE distinguish control channel and PDSCH.

When transport block size is identical with existing DCI format sizes, it can be polymerize by using the resource granularity different from DCI format or different running time-frequency resource positions or clearly instruction progress Difference.

Further, in each above-mentioned embodiment, whether the PDSCH for current transmission is to monitor module（I.e. whether UE sides need to carry out blind Detecting）, base station can determine that the PDSCH is listening mode according to preset rules, or, send the 6th to UE and signal PDSCH described in the UE for listening mode.

Accordingly, UE can determine that the PDSCH is listening mode according to preset rules, or, the 6th signaling that base station is sent is received, and configured information in the 6th signaling determines that the PDSCH is listening mode.

Data transfer herein includes UE and receives the downlink data that base station is sent, and UE sends upstream data to base station.That is the channel of carrying data can be PDSCH and Physical Uplink Shared Channel（Physical Uplink Shared Channel, referred to as： PUSCH) .

Compared to the DCI of prior art, the present embodiment reduces the instruction content in DCI, so as to reduce the indication bit number included in DCI.Specifically, covering whole system bandwidth under different system bandwidth for existing DCI causes resource to indicate that expense is excessive, and the present embodiment considers the maximum that reduction DCI can be indicated Bandwidth or the corresponding frequency resource of maximum bandwidth, so as to reduce DCI format bit.Maximum bandwidth or the corresponding frequency resource of maximum bandwidth that DCI format can be supported, the corresponding bandwidth of for example, 6 RB can be preset or configured for this.The maximum bandwidth or the corresponding frequency resource of maximum bandwidth supported except default or configuration DCI, it can also preset or configure the frequency domain resource position that correspondence DCI supports maximum bandwidth, for example determine RB positions, LTE resource allocation type can be used when configuring the frequency domain resource position, such as type 0 or Class1 or type 2 are indicated.Wherein resource allocation type 2 supports centralization and distributed resource allocation.Wherein, LTE resource allocation type 0, is that continuous RB is divided into group, each group carries out indicating whether to use using lbit；LTE resource allocation type 1, is that discrete RB is divided into several set, first set progress is indicated whether to use, and then the RB in set is carried out to indicate whether to use；LTE resource allocation type 2, is the starting position and length of one section of continuous frequency domain resource of instruction, and supports a RB respectively positioned at 2 time slots to be pointed to identical frequency or different frequencies.

The method of the present embodiment, base station and UE first determine the scope for the DCI frequency resources indicated, first determine maximum bandwidth or the corresponding frequency resource of maximum bandwidth that DCI can be indicated, the frequency resource for data transfer is determined further according to the configured information in DCI, is carried out data transmission by the frequency resource；Because the DCI maximum bandwidths that can be indicated no longer are system bandwidths, but a less bandwidth, therefore it is used to determine that the configured information of the frequency resource used in data transfer can be reduced in DCI, indicate that content is reduced by DCI, so as to reduce signaling consumption, the efficiency of system transmission is improved.

In above-described embodiment, for the scope for the DCI frequency resources indicated, it can be determined by way of default or signal, therefore, for step 2101, the base station can be used as the scope for the DCI frequency resources indicated using default first frequency resource；Or, the base station sends the 7th signaling to the UE, and the 7th signaling includes the configured information for being used to determine the scope for the DCI frequency resources indicated.

DCI considers the value for including other indication bits outside resource allocation bit in the above example.The DCI of the present invention comprises at least resource allocation bit, can also include one or more of the other indication bit in DCI.The configured information not included in DCI can be configured by predefined or high-level signaling such as RRC or MAC CE.

Below the situation not comprising other indication bits is illustrated using 2 examples.

In the first instance, for DCI formt O, limit its maximum and support with a width of 6RB, in the first way, resource granularity is RB, and corresponding bandwidth or RB numbers are N, here value is 6, and shellfish ijDCI formatO content can be changed into：

If being superimposed a new data indication bit, total number of bits is 6 bits.

In second example, for DCI formt 0, the frequency resource scope of its maximum support is limited as 2RB, then except indicating means above-mentioned, it is contemplated that being indicated using the mode of bit map, the corresponding state of 2 bits can be 00,01,10,11, and bit can be set to represent the corresponding RB of configuration for 1, and bit represents not configuring corresponding RB for 0.

From example above as can be seen that using the method for the present embodiment, bit number shared by the instruction content in DCI can be reduced, therefore, it is possible to save signaling consumption compared with the prior art.

Alternatively, above-described embodiment, may be incorporated into semi-persistent scheduling or persistent scheduling or referred to as non-dynamic scheduling, and the DCI that particular UE is not included within the non-dynamic scheduling instruction cycle is indicated.Semi-persistent scheduling refers to the PDSCH just passed or PUSCH occurs with some cycles, such as 20ms occurs once, PDSCH or PUSCH when only most starting startup semi-persistent scheduling have corresponding DCI to indicate, PDSCH the or PUSCH DC-frees I occurred with some cycles afterwards is indicated, therefore referred to as semi-persistent scheduling.But once some just passes PDSCH or PUSCH transmission mistake, i.e. recipient and detects the backward sender's feedback NACK of mistake, then sender can send the scheduling instruction that DCI carries out HARQ re-transmissions.Due to some applications such as M2M 2 business transmission intercals possible long, such as minute rank or hour rank, UE can carry out discontinuous reception or in standby between 2 transmission times（Idle) state is in favor of economize on electricity. It can be considered to cause the cycle of non-dynamic scheduling corresponding with DRX cycle, such as make them that there is the identical cycle.Current DRX cycle maximum supports 2.56s, therefore the cycle of above-mentioned non-dynamic scheduling can be equal to the DRX cycle after extension, for example, could be arranged to the integral multiple of DRX cycle.
