Description

A kind of data transmission method and device

Technical field

The present invention relates to wireless communication technology field more particularly to a kind of data transmission methods and device.

Background technique

With the rise of Internet of Things, machine type is supported in long term evolution (LTE, Long Term Evolution) system Communication (MTC, Machine Type Communication) is increasingly taken seriously.One MTC device (MTC terminal) may tool There are many part of properties among M2M (Machine to Machine, machine and machine) communication characteristic, such as Hypomobility is passed Transmission of data amount is small, it is insensitive to communication delay, require the features such as extremely low power dissipation.Wherein, in order to reduce the cost of MTC terminal, newly A kind of user device type is defined, 1.4MHz radio frequency bandwidth is only supported in uplink and downlink.

The data transmission of MTC is dispatched by down control channel.Upstream data is carried in Uplink Shared Channel and passes Defeated, downlink data is carried in DSCH Downlink Shared Channel and transmits.Include paging (paging) message in downlink data transmission, connect at random Enter the transmission of response (Random Access Response, RAR) message and msg4 message, wherein msg4 message is to connect at random Base station is sent to the downlink contention resolution message of user equipment during entering.It is different according to the business tine of scheduling, downlink control Channel can transmit in public search space, can also search UE (User Equipment, user equipment, i.e. terminal) is exclusive Rope transmits in space.

Paging message transmits in the subframe that can transmit paging message determined according to pre-defined rule.In the same paging In subframe, the paging message of multiple user equipmenies can be transmitted, these paging messages are carried in DSCH Downlink Shared Channel, by (Paging-Radio Network Temporary Identity, paging-are wireless by the P-RNTI transmitted in public search space Network Temporary Identifier) scheduling of scrambled Physical Downlink Control Channel.

The transmission of RAR message is the msg2 message transmission in random access procedure, is carried in DSCH Downlink Shared Channel, passes through RA-RNTI (Random Access-Radio Network Temporary, the random access-transmitted in public search space Radio network temporary identifier) scheduling of scrambled Physical Downlink Control Channel.The RAR of the user equipment of corresponding identical RA-RNTI disappears Breath, which can be carried on simultaneously in the same DSCH Downlink Shared Channel, to be transmitted.

In view of under coverage enhancement mode, data transmit 6 Physical Resource Block for needing to take a narrowband (1.4MHz) (Physical Resource Block, PRB) is transmitted, to shorten iterative transfer times.I.e. a narrowband is in same height A DSCH Downlink Shared Channel can only be transmitted in frame.It is had sent under multiple physics simultaneously if received in window in down control channel Row control channel, there may be resource contentions for the transmission of data scheduled in these Physical Downlink Control Channel.For paging message, The multiple user equipmenies paged in current subframe can only all be dispatched by the same P-RNTI, but these user equipmenies Coverage enhancement grade (level) may be different, therefore number of repetition is different, the Physical Downlink Shared Channel of different numbers of repetition Need it is independently transmitted, for example, under TDM (Time-Division Multiplexing, time division multiplexing) transmission mode according to Sequencing sends PDSCH (Physical Downlink Shared Channel, the physical down of different coverage enhancement grades Shared channel), and then not under FDM (Frequency Division Multiplexing, frequency division multiplex) transmission mode It is sent with narrowband.For RAR message, if RA-RNTI used in the user equipment of different coverage enhancement grades is identical, equally There are above-mentioned similar problems.

When above-mentioned use TDM FDM mode multiplexing transmission Physical Downlink Shared Channel, to realize that TDM's or FDM is specific Scheduling indicates that DCI used in Physical Downlink Control Channel (believe by Downlink Control Information, downlink control Breath) the format bit number that is included and/or instructions field design it is different.Therefore, if user equipment can not determine that base station is sent Which kind of DCI format, the then DCI format that needs blind examination different increase power consumption, increase probability of failure.

Wherein, different coverage enhancement grades and/or iterative transfer times can only include needing to enhance to be greater than 0dB/ repetition The case where the number of transmissions is greater than 1 can also include the case where not needing coverage enhancement simultaneously, i.e. coverage enhancement is that 0dB/ repeats biography The case where defeated number is 1 (not needing to repeat to transmit) can also include needing enhancing to be greater than 0dB/ iterative transfer times to be greater than 1 The case where.

In the random access procedure, the coverage enhancement grade in the present embodiment can also be with PRACH resource collection Resource set is corresponding, the corresponding coverage enhancement grade of a PRACH resource set, PRACH resource Set includes PRACH time-frequency domain resources and preamble set；Therefore, when method of the invention is applied to random access procedure When, coverage enhancement grade can be replaced with to PRACH resource set in the present embodiment.

Wherein, Physical Shared Channel scheduled in the down control channel can include: Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH) and/or Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH).Further, the Physical Downlink Shared Channel is the physics for carrying one of the following contents DSCH Downlink Shared Channel: paging (paging) message, accidental access response message (Random Access Response, RAR), with Machine access contention solves message.

Physical Downlink Control Channel in the present embodiment is using enhancing Physical Downlink Control Channel (EPDCCH) format transmission.

In some embodiments, N number of physics with different coverage enhancement grades and/or iterative transfer times is shared The multiplexing transmission mode that channel uses, can be according to described N number of with different coverage enhancement grades and/or iterative transfer times The type of the data of Physical Shared Channel carrying is determining, the N with different coverage enhancement grades and/or iterative transfer times There are corresponding relationship, which can pre-define the multiplexing transmission mode and DCI format that a Physical Shared Channel uses, than Such as, pre-define a multiplexing transmission mode and DCI format mapping table, the mapping table be configurable on base station side and User equipment side.In this way, user equipment can judge that the physics is shared according to the type for the data that Physical Shared Channel is carried The multiplexing transmission mode that channel uses, and then judge to dispatch the object according to the multiplexing transmission mode that the Physical Shared Channel uses DCI format used in the down control channel of shared channel is managed, in this case, base station is without sending down control channel institute The instruction information of the DCI format used.Wherein, the type of the data of Physical Shared Channel carrying can pass through RNTI and transmission Subframe position judges, for example, (being carried on using P-RNTI to paging message in the preconfigured paging subframe of system In PDSCH) and scheduling paging message Physical Downlink Control Channel scrambled, RAR message transmission subframe in use RA-RNTI scrambles the Physical Downlink Control Channel of RAR message (being carried in PDSCH) and scheduling RAR message.

Wherein, the data of N number of Physical Shared Channel carrying with different coverage enhancement grades and/or iterative transfer times Type, the corresponding relationship of the multiplexing transmission mode used with the Physical Shared Channel, it may include following several situations:

Situation 1: if N number of Physical Shared Channel with different coverage enhancement grades and/or iterative transfer times is held Paging message is carried, then the Physical Shared Channel uses TDM mode multiplexing transmission；

Wherein, the TDM mode indicates that the user with different coverage enhancement grades and/or iterative transfer times sets Standby N number of Physical Shared Channel is transmitted according to specific sequencing；For example, have the first coverage enhancement grade and/or The Physical Shared Channel of iterative transfer times first carries out repeating transmission, completes after repeating to transmit, has second coverage enhancement etc. The Physical Shared Channel of grade and/or iterative transfer times carries out repeating transmission, and so on.

Wherein, the FDM mode indicates N number of object with different coverage enhancement grades and/or iterative transfer times Shared channel is managed to transmit in different frequency domain resources.

Situation 2: if N number of Physical Shared Channel with different coverage enhancement grades and/or iterative transfer times is held RAR message or unicast service message are carried, then the Physical Shared Channel uses FDM mode multiplexing transmission；

Situation 3: if N number of Physical Shared Channel with different coverage enhancement grades and/or iterative transfer times is held Carry RAR message or unicast service message, and exist in system bandwidth at least with coverage enhancement grade quantity is comparable can be used for passing The narrowband of transmission of data, then the Physical Shared Channel uses FDM mode multiplexing transmission, and otherwise the Physical Shared Channel uses the side TDM Formula multiplexing transmission.

Another way, N number of Physical Shared Channel carrying with different coverage enhancement grades and/or iterative transfer times Data type, can show as scheduling has N number of physics of different coverage enhancement grades and/or iterative transfer times shared It is used for scrambled RNTI type used by the Physical Downlink Control Channel of channel, in this case, there are different coverings to increase The type of the data of N number of Physical Shared Channel of strong grade and/or iterative transfer times carrying and the Physical Shared Channel use Multiplexing transmission mode corresponding relationship, can show as scheduling have different coverage enhancement grades and/or iterative transfer times N number of Physical Shared Channel Physical Downlink Control Channel used by for scrambled RNTI type and the Physical Shared Channel The corresponding relationship of the multiplexing transmission mode of use, it may include following several situations:

Situation 1: if the Physical Downlink Control Channel is scrambled using P-RNTI, the Physical Downlink Control Channel is adjusted N number of Physical Shared Channel with different coverage enhancement grades and/or iterative transfer times of degree is multiplexed biography using TDM mode It is defeated；

Situation 2: if the Physical Downlink Control Channel uses RA-RNTI or C-RNTI (Cell-Radio Network Temporary Identifier, Cell Radio Network Temporary Identifier/Identity, Cell-RNTI) or TC-RNTI (Temporary Cell-Radio Network Temporary Identifier, Temporary Cell Radio Network temporary identifier) scrambling, then the physical down control N number of Physical Shared Channel with different coverage enhancement grades and/or iterative transfer times scheduled in channel uses FDM mode Multiplexing transmission；

Situation 3: if the Physical Downlink Control Channel is scrambled using RA-RNTI or C-RNTI or TC-RNTI, and system band Exist in width at least with the comparable narrowband for transmitting data of coverage enhancement grade quantity, then the Physical Downlink Control Channel institute N number of Physical Shared Channel with different coverage enhancement grades and/or iterative transfer times of scheduling is multiplexed biography using FDM mode It is defeated, otherwise use TDM mode multiplexing transmission.

Step 103: the base station is sent under the physics using the DCI format determined and using corresponding transmission mode Row control channel.

In step 103, the Physical Downlink Control Channel is repeatable to be sent.Preferably may include it is several under several senders Formula:

Mode 1: the tune of N number of Physical Shared Channel with different coverage enhancement grades and/or iterative transfer times Degree information is sent in the same Physical Downlink Control Channel, it is further preferred that the same physical down control letter Road is according to N number of Physical Downlink Shared Channel institute with different coverage enhancement grades and/or iterative transfer times scheduled in it Maximum iterative transfer times in the iterative transfer times of corresponding Physical Downlink Control Channel carry out repeating transmission, and N is Integer greater than 1.

In such cases, optionally, N number of physics with different coverage enhancement grades and/or iterative transfer times is shared Channel corresponds to identical for scrambling the physical down control of the Physical Shared Channel and scrambling scheduling Physical Shared Channel The RNTI of channel.

Further, when the shared letter of N number of physics with different coverage enhancement grades and/or iterative transfer times When the scheduling information in road is sent in the same Physical Downlink Control Channel, DCI used in the Physical Downlink Control Channel In to include at least the N number of physics with different coverage enhancement grades and/or iterative transfer times being used to indicate scheduled in it total The scheduling information of channel is enjoyed, the scheduling information is concatenated together according to particular order, wherein there are different coverage enhancement grades And/or each instructions field of the scheduling information of the Physical Shared Channel of iterative transfer times is completely independent or part instructions field is total It enjoys, part instructions field independence.

It specifically, here include that there are different coverage enhancement grades scheduled in the Physical Downlink Control Channel And/or the Physical Shared Channel of iterative transfer times uses two kinds of situations of TDM or FDM mode multiplexing transmission, corresponds in the DCI In the scheduling information of N number of Physical Shared Channel include at least one instructions field be it is independent to N number of Physical Shared Channel, other refer to Show that domain can be independent or shared.For TDM mode, when independent instructions field can each share the transmission of channel for independent instruction Between section information, transmission period information includes original transmission subframe and terminates subframe, or including original transmission subframe and again Multiple the number of transmissions, or only include original transmission subframe；For FDM mode, independent instructions field can be each altogether for independent instruction The information of the frequency domain position of channel is enjoyed, frequency domain location information includes the transmission position PRB and/or transmission narrowband position.

Mode 2: the tune of N number of Physical Shared Channel with different coverage enhancement grades and/or iterative transfer times N number of physical down according to chronological order transmission of the information in the same down control channel transmission period is spent to control Sent in channel, N number of Physical Downlink Control Channel respectively according to scheduled in it have different coverage enhancement grades and/or The weight of Physical Downlink Control Channel corresponding to a Physical Shared Channel in N number of Physical Shared Channel of iterative transfer times Multiple the number of transmissions carries out repeating transmission, and N is the integer greater than 1.

In such cases, optionally, N number of physics with different coverage enhancement grades and/or iterative transfer times is shared Channel corresponds to the same or different physics for scrambling the Physical Shared Channel and scrambling the scheduling Physical Shared Channel The RNTI of down control channel.

Further, when the shared letter of N number of physics with different coverage enhancement grades and/or iterative transfer times Under N number of physics according to chronological order transmission of the scheduling information in road in the same down control channel transmission period When being sent in row control channel, it may include following two situation:

Situation 1: if N number of Physical Downlink Control Channel dispatch respectively have different coverage enhancement grades and/ Or N number of Physical Shared Channel of iterative transfer times uses TDM mode multiplexing transmission, then N number of Physical Downlink Control Channel It includes at least to be used to indicate scheduled in it in used DCI and there are different coverage enhancement grades and/or iterative transfer times N number of Physical Shared Channel in a Physical Shared Channel transmission period information, the transmission period packet It includes original transmission subframe and terminates subframe, perhaps include that starting is passed including original transmission subframe and iterative transfer times or only Defeated subframe；

Situation 2: if N number of Physical Downlink Control Channel dispatch respectively have different coverage enhancement grades and/ Or N number of Physical Shared Channel of iterative transfer times uses FDM mode multiplexing transmission, then N number of Physical Downlink Control Channel It includes at least to be used to indicate scheduled in it in used DCI and there are different coverage enhancement grades and/or iterative transfer times N number of Physical Shared Channel in a Physical Shared Channel frequency domain position information, frequency domain position letter Breath includes the transmission position PRB and/or transmission narrowband position.

Optionally, in some embodiments, before the step 103 of above-mentioned process, it can also include the steps of and (do not scheming Shown in 1):

Step 102: the base station sends the instruction information of DCI format used in the Physical Downlink Control Channel.

Preferably, the instruction information sent in step 102 may include following several situations:

Situation 1: the instruction information is used to indicate described with different coverage enhancement grades and/or iterative transfer times The multiplexing transmission mode that N number of Physical Shared Channel uses, wherein described that there are different coverage enhancement grades and/or repeat to transmit The corresponding relationship of multiplexing transmission mode and DCI format that N number of Physical Shared Channel of number uses is pre-defined, for example, can be pre- First define the multiplexing transmission mode of Physical Shared Channel use and the mapping table of DCI format.Further, the corresponding relationship Table is configurable on base station side and user equipment side, in this way, user equipment can pass through inquiry according to the instruction information received The mapping table determines corresponding DCI format.

As an example, which can be 1 bit indication information, which is used to refer to institute It states N number of Physical Shared Channel and FDM mode multiplexing transmission is still used using TDM mode multiplexing transmission.

Situation 2: the instruction information is used to indicate DCI format used in the Physical Downlink Control Channel, such as should DCI format is the corresponding DCI format of TDM or the corresponding DCI format of FDM, wherein described to have different coverage enhancement grades And/or N number of Physical Shared Channel of iterative transfer times multiplexing transmission mode used and the corresponding relationship of DCI format are determined in advance Justice.For example, the multiplexing transmission mode of Physical Shared Channel use and the mapping table of DCI format can be pre-defined.

As an example, which can be 1 bit indication information, which is used to refer to object Managing DCI format used in down control channel is the corresponding DCI format of TDM mode or the corresponding DCI format of FDM mode.

Situation 3: the instruction information is used to indicate described with different coverage enhancement grades and/or iterative transfer times The corresponding relationship of multiplexing transmission mode and DCI format that N number of Physical Shared Channel uses.For example, it is shared to pre-define physics The mapping table of multiplexing transmission mode and DCI format that channel uses, the mapping table are configurable on base station side and user Equipment side.

As an example, every kind of corresponding relationship in the mapping table may be provided with unique identification, and base station is sent Instruction information can be the unique identification of one of mapping table corresponding relationship, in this way, user equipment can basis The instruction information received determines corresponding DCI format by inquiring the mapping table.

Preferably, in step 102, the instruction information, which can be carried in system information, to be sent, and can also be carried on the object It is sent in DCI used in reason down control channel.Certainly, the embodiment of the present invention is not excluded for sending the instruction using other modes The method of information.It sends if the instruction information is carried in system information, preferably, can be carried in system information In 1 bit indication domain.It is sent if the instruction information is carried in the bit field of DCI, preferably, carries the instruction information Bit field can be the bit field that can be preferentially resolved in the DCI, such as first in DCI bit field, more into one Step ground, the bit field for carrying the instruction information can be 1 bit indication domain.

In the case where above-mentioned instruction information is carried on transmission in system information, in some embodiments it may be preferred that adjusting Spend N number of Physical Shared Channel with different coverage enhancement grades and/or iterative transfer times that multiplexing transmission mode is TDM Physical Downlink Control Channel is that transmitting with different coverage enhancement grades and/or repetition for FDM is secondary from dispatching multiplex transmission mode The Physical Downlink Control Channel of several N number of Physical Shared Channels, the amount of bits for the DCI format that the two uses are identical or different.

In the case where the instruction information is carried on transmission in system information, in further embodiments, it is preferable that adjust Spend N number of Physical Shared Channel with different coverage enhancement grades and/or iterative transfer times that multiplexing transmission mode is TDM Physical Downlink Control Channel is that transmitting with different coverage enhancement grades and/or repetition for FDM is secondary from dispatching multiplex transmission mode The Physical Downlink Control Channel of several N number of Physical Shared Channels, instructions field included in DCI format used in the two are identical Or it is different.

This is because even if the amount of bits of DCI format used in the two is different, or the instructions field for being included is not Together, it but since user equipment is before receiving Physical Downlink Control Channel, can be determined according to the instruction information in system information Used DCI format, therefore, user equipment, can be only right according to DCI format institute when receiving Physical Downlink Control Channel The bit length answered is attempted to receive, if RNTI and CRC check all pass through, illustrates that the DCI corresponds to the user equipment, Ke Yijin One step obtains the scheduling information of the Physical Shared Channel of itself according to instructions field content defined in the DCI format, therefore not There are problems that needing the multiple DCI sizes of blind examination, does not increase blind examination number, power overhead is small.

Wherein, the instructions field that the two includes is identical, can refer to that the quantity for the instructions field that the two includes is identical, be also possible to Refer to that the quantity for the instructions field that the two includes is identical and arrangement mode is identical.

In the case where above-mentioned instruction information is carried on transmission in DCI used in the Physical Downlink Control Channel, Optionally, dispatching multiplex transmission mode is the described N number of with different coverage enhancement grades and/or iterative transfer times of TDM The Physical Downlink Control Channel of Physical Shared Channel has different coverage enhancements from dispatching multiplex transmission mode described in TDM The Physical Downlink Control Channel of N number of Physical Shared Channel of grade and/or iterative transfer times, the DCI format that the two uses Amount of bits is identical.This is because user equipment not can determine that the physical down before receiving Physical Downlink Control Channel DCI format used in control channel only read the instruction information in the DCI that Physical Downlink Control Channel is carried When, it just can determine that DCI format, therefore, if the bit length of difference DCI is different, user equipment is receiving physical down control It needs to attempt respectively according to different bit lengths when channel processed, i.e., according to different DCI bit length blind examinations, will increase false retrieval Probability and power overhead；So when need to design the amount of bits of DCI format corresponding to FDM and TDM multiplexing transmission mode To be identical, such user equipment, can be according only to a fixed DCI bit length when receiving Physical Downlink Control Channel Go attempt receive, this is the specific instructions field that not can read in DCI, therefore it is only necessary to know that DCI bit length, such as Fruit RNTI and CRC check all pass through, and illustrate that the DCI corresponds to the user equipment, then the user equipment is further read Specific bit field in DCI is at this time usually to read in sequence, if the information for indicating DCI type is placed in DCI In first bit field, user equipment first reads this bit field, so that it may know the subsequent bits domain in this DCI be according to For the mode of FDM or TDM scheduling Physical Shared Channel come what is realized, such user equipment is assured that the instructions field in DCI Cascade system, so as to according to the sortord and content type of instructions field each in the DCI format under the cascade system come DCI is read, and then reduces the number for attempting parsing DCI compared with prior art, that is, reduces blind examination number.

By above description as can be seen that in the embodiment of the present invention, base station is determined used in Physical Downlink Control Channel DCI format, the Physical Downlink Control Channel are used to dispatch the N with different coverage enhancement grades and/or iterative transfer times A Physical Shared Channel, base station send the physical down control using the DCI format determined and using corresponding transmission mode Channel processed.The DCI format as used in the Physical Downlink Control Channel, and scheduled in the Physical Downlink Control Channel The multiplexing transmission mode that N number of Physical Shared Channel uses is related, so that user equipment can be used and N number of physics The relevant DCI format of multiplexing transmission mode that shared channel uses receives Physical Downlink Control Channel, to reduce user equipment To the blind detection operation of Physical Downlink Control Channel.

Step 201: user equipment determines DCI format used in Physical Downlink Control Channel, the physical down control Channel is used to dispatch N number of Physical Shared Channel with different coverage enhancement grades and/or iterative transfer times, under the physics DCI format used in row control channel is related to the multiplexing transmission mode that N number of Physical Shared Channel uses.

Specifically, user equipment can according to the notice of system information, or according to scheduling Physical Shared Channel physics under The notice of bit field in DCI used in row control channel, or the type of data carried according to Physical Shared Channel, To determine that the user equipment needs the DCI format that detects.Wherein, if base station uses SIB (System Information Block, system information block) notice mode, then user equipment before determining DCI format, first obtain instruction information, then sentence Disconnected DCI format out receives Physical Downlink Control Channel according to the corresponding bit number of the DCI format, and is further therefrom obtained from The scheduling information of the Physical Shared Channel of body；If base station is by the way of DCI notice, user equipment needs first according to specific DCI size receives Physical Downlink Control Channel, then reads instruction information therein, DCI format is determined, further according to DCI format The scheduling information of the Physical Shared Channel of the user equipment is obtained from the Physical Downlink Control Channel.

Wherein, different coverage enhancement grades and/or iterative transfer times can only include needing to enhance to be greater than 0dB/ repetition The case where the number of transmissions is greater than 1 can also include the case where not needing coverage enhancement simultaneously, i.e. coverage enhancement is that 0dB/ repeats biography The case where defeated number is 1 (not needing to repeat) can also include needing to enhance to be greater than the feelings that 0dB/ iterative transfer times are greater than 1 Condition.

Wherein, the Physical Shared Channel can include: Physical Downlink Shared Channel and/or Physical Uplink Shared Channel.More Further, the Physical Downlink Shared Channel is the Physical Downlink Shared Channel for carrying one of the following contents: paging message, with Machine accesses response message, random access contention resolution message.

In some embodiments, N number of physics with different coverage enhancement grades and/or iterative transfer times is shared The multiplexing transmission mode that channel uses, can be according to described N number of with different coverage enhancement grades and/or iterative transfer times The type of the data of Physical Shared Channel carrying is determining, the N with different coverage enhancement grades and/or iterative transfer times There are corresponding relationship, which can pre-define the multiplexing transmission mode and DCI format that a Physical Shared Channel uses.

Situation 2: if N number of Physical Shared Channel with different coverage enhancement grades and/or iterative transfer times is held RAR message or unicast service message are carried, then the Physical Shared Channel is sent using FDM mode；

Situation 2: if the Physical Downlink Control Channel is scrambled using RA-RNTI or C-RNTI or TC-RNTI, the object Manage N number of Physical Shared Channel scheduled in down control channel with different coverage enhancement grades and/or iterative transfer times Using FDM mode multiplexing transmission；
