Other information；

UE can obtain starting Physical Resource Block (Physical Resource according to the value and corresponding calculation method of RIV Block, PRB) position (RB_START) and distribution continuous physical resource block quantity (L_CRBs).If frequency hopping is identified as 0, resource point With in instruction only include RIV, in this case, Physical Uplink Shared Channel (Physical Uplink Share Channel, PUSCH) from resource block RB_STARTStart the Continuous Mappings L in such a way that resource block index is incremented by_CRBsA resource block； If frequency hopping is identified as 1, information and RIV, in this case, first are distributed comprising frequency-hopping resource simultaneously in resource distribution instruction The PUSCH resource allocation of a time slot (or HARQ transmission number be even number subframe) and second time slot (or HARQ transmission number For the subframe of odd number) PUSCH resource allocation can be according to RIV, frequency-hopping resource distribution information and other possible information (such as cells Specific frequency hopping pattern, mirror image pattern etc.) it obtains.

It should be pointed out that ascending resource distribution is directed to whole system bandwidth in LTE/LTE-A system, that is, exist PUSCH transmission resource of one or more PRB as distribution is selected in up-link bandwidth in all available PRB.Due to LTE/LTE-A using DFT-S-OFDM uplink scheme, if therefore distribution PRB quantity be greater than one, these PRB is continuous on frequency domain.

In following wireless communication system, whole system bandwidth can be divided into several portions of bandwidth (Bandwidth Part, BWP).For any one UE, a uplink BWP is only had in synchronization and is activated.Therefore, in the following channel radio The distribution of ascending resource needs simultaneously to include the instruction of BWP and the instruction of PRB in BWP in the UL Grant of letter system.In addition, not Cyclic prefix-orthogonal frequency division multiplexing (Cycle Prefix-Orthogonal can be supported simultaneously by carrying out wireless communication system Frequency Division Multiplexing, CP-OFDM) and discrete Fourier transform spread spectrum orthogonal frequency division multiplexing it is more (Discrete Fourier Transform-Spread-Orthogonal Frequency Division is accessed in location Multiplexing, DFT-S-OFDM) uplink scheme, if therefore distribution PRB quantity be greater than one, these PRB It may be continuous on frequency domain, it is also possible to discrete, it is also possible to which part is continuous；On the other hand, if in UL Grant Frequency hopping instruction is contained, then the frequency hopping of ascending resource can carry out in same BWP, can also carry out between different BWP.

The embodiment of the present invention is the process that UE transmits UL data by Msg3

In practical applications, NB-IOT UE and eMTC UE often supports some small data packets business, if by normal Rule way transmits these small data packets establishing with base station again after RRC connect, then the control signaling for being used to establish RRC connection is opened Sell very big, transmission relative to small data packets not economical and effective, furthermore the propagation delay time of UE data is also very big.A kind of optimization side Method is just to transmit small data packets as early as possible in the Msg3 of RACH process, then the propagation delay time and UE power consumption to data can all have pole It is big to improve, it can also save many unnecessary control signaling expenses.Following embodiments describe UE and transmit UL data by Msg3 Process.

Figure 18 is the flow diagram that UE transmits UL data by Msg3.The first step, the PRACH that UE is configured in base station A PRACH resource is arbitrarily selected to send Msg1 (i.e. PRACH preamble) in resource pool, regardless of whether UE will pass in Msg3 Defeated UL data, the PRACH resource pool used are all same.

Second step sends corresponding Msg2 (being carried by PDSCH), and in the UL of RAR if base station detects the Msg1 Two Physical Resource Block of different sizes are distributed in Grant, two Physical Resource Block correspond to different TBS values.Wherein big TBS Value is in MAC/RRC layers of UL data and UE ID etc. necessary control signaling of Msg3 transmission, small TBS value in Msg3 for only to pass MAC/RRC layers of defeated UE ID etc. necessary control signaling.

It is impacted in order not to the UE to previous version, first UL grant can be sent out according to the format of previous version It send.For example, the UL grant in RAR can indicate 88 bits for NB-IoT.Second UL grant can use original RAR Reservation (reserved) information bit in format indicates new TBS table.In another example, base station sends two Msg2, i.e. two PDSCH give the same UE.Alternatively, base station sends a PDSCH, including the MAC PDU of two RAR, divide It Zhi Shi not two UL grant.Alternatively, base station sends the MAC PDU of a RAR, with an additional MCS of reservation bit instruction Table is used to refer to additional TBS, and other parameters are identical as another UL grant, for example, frequency domain resource position, or Time domain initial position, TA (timing advance), TPC command etc..

Third step, UE receive the Msg2, and according to whether to transmit UL data in Msg3 selects corresponding TBS value, and Msg3 (being carried by PUSCH) is sent on corresponding Physical Resource Block.For example, if the caching (buffer) of UE is inner UL data It sends, then the larger TBS and corresponding Physical Resource Block that are distributed in selection RAR grant；If do not had in the caching of UE UL data need to send, i.e., do not transmit UL data in Msg3, then the smaller TBS that distributes and corresponding in selection RAR grant Physical Resource Block.

4th step, decoding Msg3 is all attempted in base station in two pieces of resources that RAR grant is distributed, if in biggish physics Resource block (corresponding big TBS value) decodes Msg3, then eNB thinks that the Msg3 has the UL data for carrying UE；If lesser Physical Resource Block (corresponding small TBS value) decodes Msg3, then eNB thinks that the Msg3 does not carry the UL data of UE.Base station root Msg4 (being carried by PDSCH) is sent according to the decoding result of Msg3.

In the process of Figure 18, it is by base station in two physical resources that whether UE, which carries this information of UL data in Msg3, Block does what blind examination was known, and there is no signalings before Msg3 is sent indicates the information to base station.

It in one embodiment, is the process for supporting Figure 18, UL grant distributes two block sizes different physics money in RAR Source (corresponding different TBS values), UE can select one in two TBS values to transmit Msg3 according to self-demand.The two TBS The scheduling of resource of value can share partial scheduling information, such as subcarrier described in the 16.3.3 section of 3GPP specification 36.213 Interval instruction (1bit), subcarrier distribution information instruction (6bits), scheduling delay instruction (2bits) and number of repetition instruction (3bits).The scheduling of resource of the two TBS values is distinguished with different MCS instructions field, and the design of MCS instructions field can refer to The table 16.3.3-1 of 3GPP specification 36.213, i.e., a MCS index can be in a manner of determining modulation, RU (resource unit) number Amount and TBS value, the maximum TBS value that the two MCS instructions field are supported is different, under identical MCS index, two MCS instructions field Corresponding modulation system, RU quantity and TBS value all may be different.The two pieces of physical resources distributed in RAR grant are in frequency domain Identical, only the RU quantity of time domain is different, i.e., lesser Physical Resource Block is included in biggish Physical Resource Block.

In one example, first above-mentioned MCS instructions field can reuse the existing table of Rel-14 system (see 3GPP The table 16.3.3-1 of specification 36.213 only supports the TBS of a fixed value 88bits), the UE before Rel-15 version can be solved This MCS instructions field is read, new table (supporting bigger TBS value, such as 256bits) can be used in second MCS instructions field, only Rel-15 version and UE later can be interpreted.

If the UE before Rel-15 version receives UL grant in this RAR, will be indicated according to first MCS The scheduling in domain sends Msg3, only transmits MAC/RRC layers of UE ID etc. necessary control signaling；If Rel-15 version and UE later The ULgrant in this RAR is received, one can be selected in two MCS instructions field according to self-demand to send Msg3, If selecting second MCS instructions field, UL data can be carried in Msg3, conversely, cannot then carry UL in Msg3 Data.The signaling overheads of second MCS instructions field can occupy the reservation followed closely after the domain UL grant in existing MAC RAR Region (see domain " R " after " UL Grant " in Figure 19), then the overall overhead of existing MAC RAR remains unchanged.

In one example, first above-mentioned MCS instructions field is indicated with second MCS instructions field using the same domain, But Explanation way is determined by another domain, this is used to determine that the domain of MCS instructions field Explanation way to be 1bit.In an example In, this domain is not together in MAC RAR structure with UL grant, but occupies the MAC of existing eMTC Mode B UE First reserved bit of RAR (see first domain " R " in Figure 20).For example, then MCS refers to when the domain " R " is designated as ' 0 ' Show domain using the first Explanation way (such as the following table 1, the maximum TBS value of support are 328bits), when the domain " R " is designated as ' 1 ' When, then MCS instructions field is using second of settling mode (such as the following table 2, the maximum TBS value of support are 600bits).It in this way can be with Maintain existing MAC RAR expense constant additionally to indicate some information, with the TBS value for extending Msg3PUSCH.At another In example, this domain belongs to UL grant.

If the UE before Rel-15 version receives UL grant in this RAR, will be indicated according to first MCS The scheduling in domain (table 1) sends Msg3, only transmits MAC/RRC layers of UE ID etc. necessary control signaling；If Rel-15 version and later UE receive this RAR after, will be judged according to the value in the domain " R " in UL grant MCS instructions field using table 1 or the scheduling of table 2, And then obtain TBS value.Tables 1 and 2 is the schematic diagram of two TBS.

First TBS table of 1 CE Mode B of table

Figure 21 is the flow diagram that UE transmits UL data by Msg3.The first step, UE is according to whether in the buffer There are UL data to send and selects corresponding PRACH resource pool.UE arbitrarily selects a PRACH resource in the PRACH resource pool of selection Send Msg1.In one example, the PRACH process which initiates is contention access.

Second step, UE receives Msg2, and being interpreted according to the PRACH resource pool of selection (or the purpose for initiating PRACH) should UL grant in the RAR that Msg2 is carried, i.e., different PRACH resource pools correspond to UL grant format in different RAR.

Third step, UE send Msg3 in the UL resource that the UL grant of interpretation is distributed.Although noticing UE according to slow Whether there are UL data to send the resource for having selected NPRACH in depositing, but base station can also be decided whether according to its dispatch situation To sufficiently large TBS.Therefore, it after UE interprets UL grant, can be determined according to rule predetermined except MAC/RRC layers necessary UL data whether are carried outside control signaling, or only carry BRS (buffer status report) information.

In the process of Figure 21, UE whether will Msg3 carry UL data be that eNB is indicated to by Msg1, eNB according to It is that Msg3 dispatches a bigger TBS that corresponding RAR grant, which can be used, in the instruction, to carry the UL data of UE.

In one embodiment, in Figure 21 difference PRACH mesh using different PRACH resource pools, these are for difference The PRACH resource pool of PRACH purpose can be distinguished in code domain, time domain or frequency domain.In one example, code domain here refers to It is distinguished by PRACH preamble, such as PRACH preamble is divided for GroupA and GroupB, wherein GroupA PRACH preamble is used to transmit UL data in Msg3 for conventional PRACH purpose, the PRACH preamble of GroupB PRACH purpose.In one example, for NB-IOT UE, the PRACH resource for different PRACH purposes is configured in not On same NB-IOT carrier wave (anchor carrier or non-anchor carrier).In one example, for eMTC UE, the PRACH resource for different PRACH purposes are configured in different narrowbands (Narrow-band).

In yet another embodiment, the PRACH resource pool in Figure 21 for different PRACH purposes is by using different It is distinguished on PRACH plus around different masks (mask) sequence, PRACH here leading (preamble) is repeatedly transmitted, in weight It can be superimposed a signal sequence (i.e. every time duplicate PRACH is by unlike signal institute mask) on multiple multiple PRACH, be used for The signal sequence of mask can have multiple, and eNB is in receiving end solution blind to mask sequence to obtaining additional information.Such as 4 times Available mask sequence is transmitted in PRACH repetition { 1,1,1,1 } and { 1, -1,1-1 }, if UE is sent using { 1,1,1,1 } PRACH shows that a normal RRC connection is established in UE request, if UE sends PRACH using { 1, -1,1, -1 }, shows that UE is asked Seek the transmission UL data on Msg3.

In one embodiment, UL in the corresponding different RAR of different PRACH resource pools (or difference PRACH purpose) Grant format, the TBS possibility that UL grant is indicated in RAR here is identical may also be different, but denotable maximum TBS value is agreed Fixed difference can indicate one bigger for RAR grant corresponding to the PRACH resource pool in Msg3 transmission UL data TBS, to support also to support the transmission of UL data other than necessary MAC/RRC layers of UE ID etc. necessary control signaling.

Embodiment eight

The embodiment of the present invention is used to dispatch NB-IOT UE in the RAR grant of Msg3 transmission UL data.

Existing NB-IOT UE is a fixed value (88bits) in the assignable TBS of Msg3, referring to 3GPP Spec 36.213 table 16.3.3-1, for the transmission of the MAC/RRC such as UE ID layers of necessary control signaling, if to transmit UL in Msg3 Data, the supported TBS value of Msg3 must be extended.Following embodiments describe the TBS extension for the Msg3 of NB-IOT UE Method.

Table 3 be NB-IOT UE be used for determine Msg3 NPUSCH MCS an example, wherein the definition of design parameter and Physical meaning can be found in the 16.3.3 section content of 3GPP Spec 36.213.In the MCS table, two TBS values can be supported, such as The 88bits and 256bits provided in sample table 3.If that eNB is configured in RAR grant is minimum TBS value 88bits, that UE only transmits the MAC/RRC such as UE ID layers of necessary control signaling in Msg3；If what base station configured in RAR grant is most Big TBS value 256bits, then UE in Msg3 other than MAC/RRC layers of necessity control signaling such as transmission UE ID, can also pass Defeated UL data.

This MCS table can permit base station and flexibly decide whether that dispatch UE passes in Msg3 according to real resource distribution condition Defeated UL data, although UE requests to transmit UL data in Msg3 by dedicated PRACH resource pool, base station can not also dispatch this UE transmits UL data in Msg3.

In another embodiment, which can support multiple TBS values, i.e. eNB can be according to real resource distribution condition Flexibly decide whether that UE is allowed to carry UL data in Msg3, can also determine the UL size of data that UE is carried in Msg3.Example Such as, which can support three TBS values, wherein biography of the smallest TBS value for MAC/RRC layers of UE ID etc. necessary control signaling It is defeated, transmission of the medium TBS value for MAC/RRC layers of UE ID etc. necessary control signaling and a small amount of UL data (such as BSR), most Transmission of the big TBS value for the MAC/RRC layers of necessary control signaling such as UE ID and a large amount of UL data.

In yet another embodiment, the minimum TBS value that table 3 is supported is a predefined value (88bits), and maximum TBS value is but A not instead of predefined value, by base station in SIB (system information block) inner static configuration.In an example, base station exists Only one TBS value of configuration is used to transmit UL data in Msg 3 SIB.In another example, base station configures multiple in SIB TBS value (such as 2 or 3) be used for Msg3 transmit UL data, with flexible dispatching the Msg3 UL data packet transmitted size.

In yet another embodiment, the maximum TBS value that table 3 is supported is related with the resource pool selected in Msg1, i.e. UE can be with Selection request according to Msg1 transmits UL data in Msg3, and the TBS of corresponding size can also be requested according to the size of data of caching It is transmitted for UL data.In other words, UE can report data cached size in Msg1, and base station reports data cached according to Msg1 Size indicates that the TBS value of corresponding size carries UL data for Msg3 in Msg2.

For example, different Msg3 maximum TBS values is corresponded to there are two PRACH mask sequence, PRACH mask sequence 1,1, 1,1 } corresponding Msg3 maximum TBS value is 536bits, for transmitting more UL data, PRACH mask sequence in Msg3 { 1, -1,1, -1 } corresponding Msg3 maximum TBS value is 256bits, for transmitting less UL data in Msg3.

MCS table of the table 3 for the Msg3 NPUSCH of NB-IOT UE

Table 4 is another example for the MCS table that NB-IOT UE is used to determine Msg3 NPUSCH, and wherein design parameter is determined Justice and physical meaning can be found in the 16.3.3 section content of 3GPP Spec 36.213, and Nrep therein refers to what UE was selected in Msg1 PRACH number of repetition.The MCS/TBS table is similar with table 1, can support two TBS values, small TBS value is for only transmitting UE ID etc. MAC/RRC layers of necessary control signaling, big TBS value are used for transmission the MAC/RRC such as UE ID layers of necessary control signaling and UL number According to.

Table 4 and the difference of table 3 are that the code rate selection for supporting the TBS to transmit is repeated in the selected NPRACH of Msg1 Number is related, i.e., under the same MCS value, RU quantity corresponding to NPRACH number of repetition difference and/or modulation system may It is different.When NPRACH number of repetition is smaller, higher code rate is can be used in the Msg3 transmission for carrying UL data, and in NPRACH When number of repetition is larger, lower code rate is can be used in the Msg3 transmission for carrying UL data.

MCS table of the table 4 for the Msg3 NPUSCH of NB-IOT UE

Such as in table 4, when the selected NPRACH number of repetition of Msg1 is equal to R1, the interpretation of RU quantity is the one of table 4 Column, when the selected NPRACH number of repetition of Msg1 is equal to R2/R3, the interpretation of RU quantity is another column of table 4.Here, R1, R2 and R3 is three different numbers of repetition in the eNB NPRACH configured in SIB, and UE is according to the channel quality of oneself selection pair The NPRACH number of repetition answered.

In another embodiment, under the same MCS value, different NPRACH numbers of repetition correspond to different TBS values, such as The maximum TBS value that NPRACH number of repetition is supported when smaller can be larger, and the maximum that when NPRACH number of repetition is smaller is supported TBS value can be smaller, because more resources can be occupied by transmitting biggish TBS in Msg3 when UE channel quality is poor, if The transmission of Msg3 competes failure, then will be a kind of waste to system resource, according to UE channel quality, (corresponding NPRACH repeats secondary Number) determine that supported TBS value will be more effective.

In yet another embodiment, the number of repetition of different NPRACH corresponds to different MCS tables, i.e., in the same MCS Under index, the corresponding modulation system of the number of repetition of different NPRACH, RU quantity and TBS value may be all different.

In the feature for supporting EDT (Early Data Transmission) by Msg3, base station is receiving Msg3 It is not aware that the data volume size of UE actual needs transmission before, accurate TBS cannot be provided for Msg3, when the TBS value of Msg3 Greater than UE need transmit data volume when, UE can only be bit padding to MAC PDU, in order to reduce UE in Msg3 Padding bit number, base station provide multiple possible TBS to Msg3 and select for UE, and UE selects it according to actual size of data In a most suitable TBS transmit Msg3, in receiving end, base station needs to be Msg3 based on multiple possible TBS hypothesis Blind decoding, this blind decoding can bring additional complexity to base station, and in order to avoid this blind decoding, UE is before sending Msg3 Or when sending Msg3, TBS information used in signals base Msg3 actual transmissions, then base station can detecte out Msg3 reality Used TBS value is transmitted on border, and is decoded according to this TBS value to Msg3.

In one embodiment, eNB provides multiple possible TBS for Msg3 and selects for UE, and UE is according to real data size Suitable TBS value is selected, TBS information used in Msg3 actual transmissions is transmitted by PUCCH, and is sent before sending Msg3 To base station, then eNB can detecte out TBS information used in Msg3 actual transmissions, and Msg3 is decoded based on the TBS value, To avoid doing the blind decoding of multiple TBS hypothesis to Msg3, the specific steps of the embodiment are as shown in figure 22:

The first step, UE send a PRACH for requesting EDT to eNB.

Second step after eNB receives above-mentioned PRACH, sends RAR to UE and dispatches Msg3, and provides for Msg3 multiple Possible TBS is selected for UE.

Third step, after UE receives above-mentioned RAR, the data volume size according to transmission is that Msg3 selects one of TBS value, And selected TBS information is sent to base station by PUCCH.

4th, UE is based on selected TBS value, after sending above-mentioned PUCCH, and then sends Msg3.

In the above-described embodiments, base station provides most 4 possible TBS for Msg3 and selects for UE, i.e. Msg3 actual transmissions Used TBS information can indicate that the PUCCH for carrying 1~2bits TBS information can be weighed by most 2bits With existing PUCCH format.

In one example, it is for carrying the PUCCH format of TBS information used in Msg3 actual transmissions with base station The quantity of possible TBS provided by Msg3 is related, and this quantity may be with the maximum of the Msg3 broadcasted in system information TBS value is related, it is also possible to related with the Real-Time Scheduling of base station.It, can such as when base station provides 2 TBS for UE selection for Msg3 The 1bit information is carried using existing PUCCH format 1a；And when base station provides 3~4 TBS for UE selection for Msg3, Existing PUCCH format 1b can be used to carry the 2bit information.

In another example, fixed to use PUCCH format when base station, which provides 2~4 TBS for Msg3, to be selected for UE 1b carries TBS information used in Msg3 actual transmissions.

For eMTC UE, with reference to the description of HARQ-ACK resource that saves of 10.1.2.1 of existing standard 3GPP 36.213, When the MPDCCH-PRB-set for dispatching Msg2 is configured to distributed transmission, the resource of the PUCCH is according to following formula meter It obtains:

When MPDCCH-PRB-set is configured to localized transmission, calculation formula can be obtained similarly.Wherein, p₀For antenna Port numbers.Q is the call number for dispatching the MPDCCH-PRB-set of Msg2.n_ECCE,qIt is MPDCCH occupied of Msg2 The call number of beginning CCE.It is base station to MPDCCH-PRB-set_qThe PUCCH parameter configured (with reference to PUCCH resource).

In one example, the parameterParameter used in PUCCH with the ACK/NACK for carrying Msg4 is same One, i.e. the parameter n1PUCCH-AN-InfoList-r13 that broadcasts in system information of base station, configure for each CE level It is corresponding to refer to PUCCH resource value；In another example, the parameterDedicated for carrying Msg3 actual transmissions institute The PUCCH of the TBS information used, different from parameter used in the PUCCH for the ACK/NACK for carrying Msg4, new parameter can order Entitled n1PUCCH-Msg3-InfoList-r15, it is similar with existing parameter n1PUCCH-AN-InfoList-r13, by base station It is broadcasted in system information, and configures corresponding reference PUCCH resource value for each CE level.

Wherein RAR_ID is call number of the RAR of the UE in affiliated MAC PDU, can include in the MAC PDU of Msg2 One or more MAC RAR, for example, MAC PDU first MAC RAR RAR_ID=0, the RAR_ID of n-th MAC RAR =N-1.In another example, RAR_ID preamble ID as used in Msg1PRACH in above-mentioned calculation formula is taken Generation.

In another example, the calculation formula of the resource of above-mentioned PUCCH is (RAR_ID and other descriptions can reuse):

Wherein, Δ_AROThe domain the ARO instruction for being included by the MPDCCH of Msg2, indicated value are interpreted according to table 10, table The table 10.1.2.1-1 of the 3GPP 36.213 of the 10 existing standards of reference.

In the above-described embodiments, the sending time for carrying the PUCCH of TBS information used in Msg3 actual transmissions, reuses The determination method of the sending time of Msg3 in existing system, such as 6th subframe of the UE after receiving Msg2 send and are somebody's turn to do PUCCH, and existing Msg3 can then be sent after the PUCCH.

In the above-described embodiments, for carrying the number of repetition of the PUCCH of TBS information used in Msg3 actual transmissions, Identical as the number of repetition of the PUCCH of the ACK/NACK for carrying Msg4, i.e., base station is each CE in system information The number of repetition of the PUCCH of level configuration.

In the above-described embodiments, which sends before Msg3, and the time relationship between the PUCCH and Msg3 is deferred to One predefined rule.For example, Msg3 is sent after the PUCCH, i.e. 1st son of the UE after sending the PUCCH Frame sends Msg3, if the PUCCH attaches most importance to, recurrence is sent, 1st subframe hair of the UE after sending the last one subframe of the PUCCH Send Msg3.In another example, the PUCCH and Msg3 have a fixed interval, to reserve decoding of the base station to the PUCCH Time, for example, 3rd subframe of the UE after sending the PUCCH sends Msg3, if the PUCCH attaches most importance to, recurrence is sent, and UE is being sent out The 3rd subframe after giving the last one subframe of the PUCCH sends Msg3.

In the above-described embodiments, when base station is that Msg3 only provides a TBS value, which then abides by without transmission, Msg3 From existing sending time, i.e. 6th subframe of the UE after receiving Msg2 sends Msg3.

For NB-IOT UE, TBS information used in Msg3 actual transmissions is transmitted by NPUSCH format 2, in existing system In system, the running time-frequency resource of NPUSCH format 2 works as NPUSCH by corresponding to the 4 dominant instructions of bit HARQ-ACK resource instructions field of DCI Format 2 is for when carrying TBS information used in Msg3 actual transmissions, corresponding resource to be as indicated by the DCI for dispatching Msg2 HARQ-ACK resource and RAR_ID joint determine, such as determine according to the following formula:

Resource_index=(AN_resource+RAR_ID) mod16

Wherein, the indicated value (0~15) that AN_resource includes by the MPDCCH of Msg2, RAR_ID are the RAR of the UE Index in affiliated MAC PDU, the Resource_index range being calculated is 0~15, further according to existing 11 He of table Table 12 determines the running time-frequency resource of corresponding NPUSCH format 2, table 11 and table 12 with reference to the table of existing standard 3GPP 36.213 16.4.2-1 with table 16.4.2-2.

In another example, above-mentioned Resource_index determines that (RAR_ID and other descriptions can according to following equation To reuse):

Resource_index=RAR_IDmod16

The running time-frequency resource of PUCCH determines when 11 subcarrier spacing of table is 3.75kHz

Table 12: the running time-frequency resource of PUCCH determines when subcarrier spacing is 15kHz

For NB-IOT UE, the sending time of Msg3 is aobvious by the instructions field of 2 bit scheduling delays in RAR grant Property instruction, base station when dispatch Msg3 it is ensured that carry Msg3 NPUSCH format 1 carrying Msg3 actual transmissions used in It is sent after the NPUSCH format 2 of TBS information, if NPUSCH format 2 is attached most importance to, recurrence is sent, it is ensured that on complete send It states NPUSCH format 2 and then starts the transmission of above-mentioned NPUSCH format 1.

In one example, it carries the NPUSCH format 1 of Msg3 and carries TBS information used in Msg3 actual transmissions There is predefined time relationship between NPUSCH format 2, it can be according to the predefined time relationship and above-mentioned NPUSCH The sending time of format 2 determines the sending time of NPUSCH format 1, or according to the predefined time relationship and above-mentioned The sending time of NPUSCH format 2 determines the sending time of NPUSCH format 1.

In one example, the sending time for carrying the NPUSCH format 2 of TBS information used in Msg3 actual transmissions exists It is indicated in corresponding RAR grant, such as by a dedicated 2 bit indication domain, ginseng is shown in Table 13, table 13 is with reference to existing The table 16.5.1-1 of standard 3GPP 36.213, the NPUSCH format 1 for carrying Msg3 are located next to hair after the NPUSCH format 2 It send.

In another embodiment, eNB provides multiple possible TBS for Msg3 and selects for UE, and UE is big according to real data Small to select suitable TBS value, TBS information used in Msg3 actual transmissions is transmitted by Msg3 piggyback, is being sent Base station is sent to when Msg3 together, then eNB can detecte out TBS information used in Msg3 actual transmissions, and is based on the TBS Value decodes Msg3, to avoid being Msg3 the blind decoding that multiple TBS assume, the specific steps of the embodiment such as Figure 23 institute Show:

The first step, UE send a PRACH for requesting EDT to eNB.

Third step, after UE receives above-mentioned RAR, the data volume size according to transmission selects one of TBS to send Msg3, and selected TBS information is sent to base station by Msg3 piggyback.

In the above-described embodiments, base station provides most 4 possible TBS for Msg3 and selects for UE, i.e. Msg3 actual transmissions Used TBS information can indicate by most 2 bits, which can occupy the part resource of Msg3 to transmit, When base station is that Msg3 only provides a TBS, the TBS information is without transmission.

In one example, when base station provides 2~4 possible TBS for Msg3, used in Msg3 actual transmissions The fixation of TBS information is indicated using 2 bit informations.In another example, when base station provides 3~4 possible TBS for Msg3 When, TBS information used in Msg3 actual transmissions is indicated using 2 bit informations, when base station for Msg3 provide 2 it is possible When TBS, TBS information used in Msg3 actual transmissions is indicated using 1 bit information.

In one example, when TBS information is transmitted by Msg3 piggback, the RE quantity for carrying TBS information is One fixed value.In another example, the RE quantity and the one or more of following factor for carrying TBS information have It closes, these factors include the bit number of TBS information, base station is supplied to multiple possible TBS values of Msg3, Msg3 is distributed in base station Whole RE number (in a subframe) etc..

In one example, only related with the bit number of TBS information for carrying the RE quantity of TBS information, such as work as TBS When information is 1 bit, occupied RE quantity is N, and when TBS information is 2 bit, occupied RE quantity is 2N.

In one example, the RE quantity for carrying TBS information and existing 1~2 bit HARQ-ACK are in PUSCH The determining method of occupied RE quantity is identical when piggyback.In another example, for carrying the RE number of TBS information It measures identical as the determining method of existing CSI occupied RE quantity in PUSCHpiggyback.

In one example, the coding mode of TBS information and existing 1~2 bit HARQ-ACK are in PUSCH Used coding mode is identical when piggyback, as repeated encoding.In another example, the coding mode of TBS information In PUSCH piggyback, used coding mode is identical with existing CSI, as Reed-Muller coding.
