In the embodiment of the present invention, upstream data can be new biography transmission of data or retransmit data, wherein, it is optionally, new to transmit Data can be first new transmission number that data transmission based on UL grant free or user equipment are transmitted to base station According to being the data transmission based on UL grant free, it can be the number based on UL grant free or UL grant to retransmit data According to transmission.For example, user equipment is based on UL grant free after base station transmission new biography data, base station receives the new transmission number According to but fail by demodulation or decoding etc. handle the new biography transmission of data, then base station can the new transmission be dispatched based on UL grant Data are retransmitted.For another example, user equipment is in the case where uplink caching is not zero, based on UL grant free to base It stands and transmits first new biography transmission of data, the upstream data transmitted after this (new biography transmission of data retransmits data) is to be based on UL grant are transmitted, until the caching of user equipment is zero.
In embodiments of the present invention, upstream data can include the uplink business data of user device transmissions, can also wrap The uplink business data and uplink reference signals of user device transmissions are included, wherein, which can be used for industry The demodulation for data of being engaged in.Ascending control information can include the corresponding hybrid automatic repeat-request (Hybrid of upstream data Automatic Repeat Request, HARQ) information, wherein, which includes following at least one：HARQ processes Number (HARQ Process Number, HPN), new data instruction (New Data Indication, NDI) information, redundancy versions (Redundancy Version, RV) information (merges) for accurately completing the HARQ of upstream data.Optionally, upload control is believed Breath only includes HARQ information.Optionally, ascending control information can also include following at least one：Modulation and Coding Scheme (Modulation Coding Scheme, MCS), resource allocation (Resource Allocation, RA) information, upstream data Corresponding transport block size (Transmission Block Size, TBS), transmission power control (Transmission Power Control, TPC), user equipment identification (User Equipment Identification, UE ID) etc..Optionally, More generally, the ascending control information based on UL grant free is properly termed as GCI (Grant-free Control again Information), which can include being used for dispatching uplink data transmission in existing LTE system or future 5G communication systems The content that includes of Downlink Control Information, by taking LTE system as an example, GCI can include in UL grant at least one of Row control information, in LTE system, UL grant can pass through (the Downlink Control of descending control information format 0 Information Format 0, DCI Format 0), DCI format 4, DCI format 0A, DCI format 0B, DCI format 4A, DCI format 4B are represented, but be also not necessarily limited to this.
Optionally, above- mentioned information can be that the RRC signaling sent by base station is pre-configured or is made a reservation for by base station Justice, but user equipment determines the ascending control information used, is that user equipment oneself selects and is reported to base station.
In the embodiment of the present invention, HPN can be used for distinguishing different upstream datas.When user carries out transmitting uplink data When, in order to ensure the efficiency of transmission of upstream data, base station can be after the upstream data of user device transmissions be received, to the user Equipment feedback acknowledgment response (Acknowledgement, ACK) or non-acknowledgement response (Non-Acknowledgement, NACK). Since base station needs certain time to processing such as the demodulation or decodings of upstream data, in order to promote uplink efficiency, Yong Hushe In the standby time range that can handle upstream data in base station, continue to send upstream data to base station.For the ease of identification of base stations Different upstream data carries out HARQ merging treatments to upstream data, can introduce HPN, user equipment is by the way that HPN is reported to Base station allows base station to distinguish the different upstream datas of user device transmissions according to the HPN.For example, base station is at a time right All upstream datas for receiving receive and the upstream data of non-feeding back ACK either NACK carries out ACK or NACK feedbacks.Such as Shown in Fig. 2 c, Fig. 2 c are the signal that the base station that one embodiment of the present of invention provides feeds back multiple ACK or NACK in synchronization Figure, base station is respectively received through the PUSCH-1 upstream datas transmitted in first TTI and second TTI and passes through PUSCH-2 The upstream data of transmission, and feeding back ACK or NACK in the 4th TTI, wherein, which is to be carried on physical uplink to be total to It enjoys and being transmitted in channel (Physical Uplink Shared Channel, PUSCH).When base station receives HPN, Ke Yigen Different upstream datas is distinguished according to the HPN.
As shown in Figure 2 d, Fig. 2 d are a kind of data transmission signal for not carrying NDI that one embodiment of the present of invention provides Figure.User equipment sends upstream data A in first TTI and assumes that the corresponding HPN of upstream data A are 1；Base station receives this The operations such as be decoded after upstream data A, determine upstream data A receive it is correct and particular moment (such as third TTI) to Family equipment carries out ACK feedbacks；It is NACK that if user equipment, which does not receive ACK or receives ACK but error detection, user equipment meeting Base station is mistakenly considered to be not received by upstream data A or receive the processing failures such as upstream data A but decoding, at this moment, user equipment Upstream data A (being assumed to be A ') is retransmitted in particular moment (such as the 5th TTI), at this moment the corresponding HPN of upstream data A ' It is 1.Assuming that base station receives upstream data A ' in the 5th TTI, and since base station is before to upstream data A feedbacks Cross ACK, then it is new data that the current base station, which can be mistakenly considered upstream data A ', thus the data are decoded etc. with operations, into Unnecessary data processing is gone.
As shown in Figure 2 e, Fig. 2 e are that another data transmission for not carrying NDI that one embodiment of the present of invention provides is shown It is intended to.User equipment sends upstream data A in first TTI and assumes that the corresponding HPN of upstream data A are 1；Base station receives Upstream data A determines that upstream data A receives mistake simultaneously by decoding etc. after processing, this be base station can particular moment (such as Third TTI) NACK feedbacks are carried out to the upstream data A received；If NACK is mistakenly detected as ACK by user equipment, User equipment can continue to send second upstream data B at particular moment (such as the 5th TTI), and the HPN of upstream data B assumes Also it is 1.It, can be because the upstream data A and corresponding HPN of upstream data B be 1 and base after base station receives upstream data B It stands and NACK feedbacks has been carried out to upstream data A, then upstream data B can be mistakenly considered the re-transmission of upstream data A by base station, thus right Upstream data A and upstream data B have carried out HARQ merging, it is clear that this merging process is inaccurate.
In the embodiment of the present invention, HARQ merging treatments are carried out to upstream data in base station, in order to ensure that HARQ is closed And accuracy reduce unnecessary data processing, base station needs to know the stylish transmission data of upstream data that user equipment is sent Or data are retransmitted, therefore introduce NDI.In the embodiment of the present invention, it may be used whether NDI overturns represent it is new biography transmission of data Or retransmit data.For example, user equipment transmits new biography transmission of data A to base station, the corresponding HPN of new biography transmission of data A are 1, then The NDI can be set as zero by user equipment；If user equipment determines that base station is not properly received upstream data A, user Equipment can retransmit upstream data to base station, and at this moment NDI remains as 0；If user equipment determines that base station has correctly received upstream data A, user equipment can be by the new upstream datas of HARQ process transmissions that HPN is 1, and at this moment NDI can be set to 1, that is, pass through NDI Overturning can distinguish new biography transmission of data or retransmit data.Optionally, the embodiment of the present invention can also be by setting NDI Fixed value come distinguish new biography transmission of data and retransmit data.For example, setting NDI=0 represents new biography transmission of data, NDI=1 represents to retransmit Data, user equipment transmit new biography transmission of data A to base station, and NDI can be set as to 0 to represent current transmission data as new transmission number According to, and if user equipment determines that base station is not properly received upstream data A, user equipment can retransmit the uplink to base station At this moment NDI can be set as 0 to represent current transmission data as re-transmission data by data A.
In embodiments of the present invention, when base station carries out the HARQ merging of upstream data, merge gain to obtain HARQ, use Different RV may be used when upstream data is retransmitted in family equipment.In order to ensure the gain of HARQ merging, user equipment can The corresponding RV of upstream data is transferred to base station by physical uplink channel.

Wherein,The subcarrier number of physical uplink channel is distributed in expression,Represent the second physical uplink The time-domain symbol number of channel occupancy represents to be used for transmission ascending control information and upstream data in the second physical uplink channel Time-domain symbol number (wherein, ascending control information and upstream data are carried in identical physical uplink channel) or represent The time-domain symbol number of upstream data is used for transmission in second physical uplink channel.With long term evolution (Long Term Evolution, LTE) for system, it is assumed that a time quantum is a subframe (Subframe), thenCalculating it is public Formula (6) is as follows：
Wherein,Represent the time-domain symbol number that second physical uplink channel, one time slot (Slot) occupies. Under normal cyclic prefix (Cyclic Prefix, CP),In the case where extending CPNDMRSRepresent this second A subframe is used for transmission the symbol numbers of DMRS on physical uplink channel, such as when the second physical uplink channel is physical uplink During shared channel (Physical Uplink Shared Channel, PUSCH), NDMRS=2.NSRSRepresent that current subframe is used for The symbol numbers of detection reference signal (Sounding Reference Signal, SRS) are transmitted, if current subframe has SRS transmission When, NSRSTo be used for transmission the time-domain symbol number of SRS, if currently without SRS transmission, NSRS=0.
Optionally, multiple upstream datas can be realized by way of orthogonal multiplex on second physical uplink channel Transmission or the transmitting uplink data for realizing multiple user equipmenies, multiplexing here refer to that multiple upstream datas can use phase Same time resource and frequency resource is transmitted, and base station can distinguish this multiple upstream data；Alternatively, multiplexing refer to it is more The transmitting uplink data of a user equipment can be transmitted, and base station being capable of area using identical time resource and frequency resource Separate the transmitting uplink data of this multiple user equipment.Multiplexing can be by the orthogonal for example multiple upstream datas of space division using different Space division code realize space division multiplexing, alternatively, multiplexing can also be realized by way of non-orthogonal multiplexing, in the embodiment of the present invention In be not especially limited.The capacity of PUCH can also be calculated by formula (7) in this case：
Wherein, VSFValue for spread spectrum coefficient.For example, by taking LTE as an example, it is assumed that physical uplink channel occupies 1 in time Subframe, and a subframe includes 2 time slots, each time slot includes 7 OFDM symbols, which occupies in frequency 12 subcarriers, and there are two the transmission that symbol is used for DMRS in a subframe, which does not include SRS, then according to formula (6) The physical uplink channel can be calculated and include 12* (2*7-2)=144 resource element (Resource Element, RE). If each RE can carry a modulation symbol, physical uplink capacity is 144 modulation symbols.
Assuming that by certain orthogonal manner, the same of 4 different upstream datas can be realized on the physical uplink channel When send, i.e. VSF=4, then according to formula (7), the capacity of the PUCH is a modulation symbol in 36 (144/4), i.e., when the physical uplink During 4 different upstream datas of channel bearing, the corresponding physical uplink channel capacity of each transmitting uplink data is 36 modulation Symbol.Wherein, the different upstream data of aforementioned four can be that a UE or multiple UE is sent.
Optionally, during the first resource that computationally row control information occupies, formula (1)~(4) can also be calculated The result arrived (using A/B/C/D as pre-allocated recourses amount, can use modulation symbol number or coded-bit with the stock number being pre-configured Number represents) it is compared.Specific formula such as (8)~(11).

In the embodiment of the present invention, the corresponding effective information bit number O of ascending control informationCICan be pre-configured by base station, Either predefined or user equipment determines that the embodiment of the present invention is not done specifically according to the hardware condition of itself It limits.For example, user equipment supports that the number of ascending HARQ caching is 8, then HPN can be represented with 3bit, i.e. OCI=3. For another example, ascending control information includes the HPN for multiple time quantums, and each time quantum corresponds to a HPN, and HPN can be used 3bit is represented, then when the HPN for having N number of time quantum (N >=1, and be natural number) needs instruction, in a kind of possible mode In, OCI=3N.
In the embodiment of the present invention, the corresponding effective information bit number of upstream data can be pre-configuration or predefined, example 32 bytes (Bytes) are set to Ru prewired.The corresponding effective information bit number of upstream data can also be in the information of a pre-configuration Change in bit number set, for example, the set of the corresponding effective information bit number of base station configuration user equipment upstream data includes K Kind bit number, specially { bit number 1, bit number 2 ... ..., bit number K }, user equipment can select uplink in the set The corresponding effective information bit number of data, and according to the corresponding effective information bit number of upstream data after selection calculates the One resource.In this manner, base station can determine the corresponding effective information bit of upstream data by way of blind Detecting Number and/or determining first resource.Optionally, the corresponding effective information bit number of upstream data can be occupied by upstream data Secondary resource MCS corresponding with the upstream data be calculated or table look-up to obtain, the Secondary resource and/or MCS can be It is being pre-configured or predefined.Still optionally further, the corresponding resource allocation of Secondary resource (Resource Allocation, RA) it is to be pre-configured, RA here includes instruction and is used for transmission the physical uplink channel of upstream data over time and frequency Position.Secondary resource can be calculated by RA in user equipment, then further according to Secondary resource and MCS, it may be determined that uplink The corresponding effective information bit number of data.Optionally, in embodiments of the present invention, the corresponding effective information bit number of upstream data Transport block size (Transmission Block Size, TBS) can be corresponded to.It should be noted that when user equipment passes through the When two resources and MCS determine upstream data corresponding effective information bit number, physically the time resource of row channel is fixed In the case of, Secondary resource can also be represented by the RB number that physical uplink channel occupies.Here time resource is fixed Refer to, by taking LTE system as an example, physical uplink channel can occupy 1 subframe in time.Therefore user equipment can pass through RB Number and MCS corresponding with upstream data, determine the corresponding effective information bit number of upstream data, such as can be by the side tabled look-up Formula (determines, which is an a pair with MCS according to RB number and the corresponding MCS of upstream data for example, by using MCS indexes It answers).
The capacity of second physical uplink channel is the physics for being used for transmission the ascending control information and the upstream data The capacity of the capacity of up channel or the physical uplink channel to be used for transmission the upstream data.Second physical uplink is believed The capacity in road can be represented or be represented with number of coded bits with modulation symbol number.The appearance of second physical uplink channel Amount can be pre-configured by base station or it is predefined or according to the corresponding targeted information bits number of upstream data and What MCS was calculated, the corresponding targeted information bits number of upstream data and/or MCS can be pre-configuration or predefined, this hair It is not especially limited in bright embodiment.
It should be noted that in embodiments of the present invention, the effective information bit number of ascending control information can be understood as The original information bits number of ascending control information or the original information bits number of ascending control information introduce cyclic redundancy school Test the information bit after (Cyclical Redundancy Check, CRC)；Correspondingly, the effective information ratio of upstream data The original information bits number of original information bits number or upstream data that special number can be understood as upstream data introduces CRC Information bit later.
By the first resource that ascending control information occupies for for number of coded bits, the method for determination of first resource has two Kind：The first, the modulation symbol that any one in above-mentioned calculation formula (1)~(4) or formula (8)~(11) is calculated Number Q 'CIIt is multiplied by the corresponding order of modulation Q of ascending control informationm, obtain first resource (being represented with number of coded bits)；Second Kind, by the modulation symbol number Q ' in above-mentioned calculation formula (1)~(4) or formula (8)~(11)CIWith number of coded bits QCI Instead of QCIFor the first resource represented with number of coded bits, while the capacity of the second physical uplink channel is also used into coded-bit Number represents, i.e., represents Q ' with Q, and Q also (is calculated) for the capacity of the second physical uplink channel with number of coded bits.Modulation Exponent number QmCorrespondence between different modulating mode is as shown in table 1.Wherein, BPSK represents binary phase shift keying (Binary Phase Shift Keying, BPSK), QPSK expressions quadriphase PSK (QuadriPhase Shift Keying, QPSK), 16QAM represents the quadrature amplitude modulation (Quadrature Amplitude Modulation, QAM) of 16 kinds of symbols, 64QAM represents that the quadrature amplitude modulation QAM, 256QAM of 64 kinds of symbols represent the QAM of 256 kinds of symbols.
