Exempt to authorize (Grant free) transmission plan that can realize that data " i.e. to walk ", terminal determination have upstream data to want When transmission, it is not necessary to through transmission uplink scheduling request and etc. the mandate of base station to be received this process, and directly data are passed through It is sent to base station after certain processing.Thus, compared to the authorized transmissions scheme of base station scheduling, propagation delay time can be greatly shortened, Avoid excessive occupancy of the control overhead to Internet resources.

Exempt from authorized transmissions to realize, before exempting from authorized transmissions, base station, which needs to preassign for terminal, available exempts to award Resource, such as ascending pilot frequency resource, running time-frequency resource etc. are weighed, and may require that and detect the data received by means such as blind Detectings From which terminal.Base station mandate is not needed since terminal sends upstream data, thus terminal detection performance becomes use How the bottleneck for exempting from the wireless communication system transmission reliability of authorized transmissions enhances the performance of terminal detection, and there is presently no very Good solution.

In the scheme for uplink transmission that the embodiment of the present invention is provided, terminal can be according to the multiple access of binding The quantity N of MAR, determines the length of the first pilot signal, is obtaining in resource (Multiple Access Resource, MAR) After the first pilot signal with the length, the MAR for the binding that placed first pilot signal is sent；In turn, the network equipment The MAR that can receive the binding of terminal transmission transmits the bundle according to the first pilot signal placed on the MAR of the binding to detect The terminal of the MAR tied up.The length of the pilot signal generated by terminal depends on the quantity with MAR in the MAR of binding, thus logical The scheme for uplink transmission that the embodiment of the present invention is provided is crossed, terminal can place connection in the resource of the MAR of binding The pilot signal of design is closed, and the pilot signal on MAR of the network equipment side to binding carries out joint-detection, to enhance use Family detection performance improves system transmission reliability.

Fig. 2 shows the method flow diagrams for uplink transmission that some embodiments of the present invention are provided.Such as Fig. 2 Shown in flow can be realized by terminal.For example, can be configured with to execute flow as shown in Figure 2 in terminal 102 as shown in Figure 1 Function module, the function module to execute the flow being implemented in combination with by hardware, software programming or software and hardware.

As shown in Fig. 2, the flow includes the following steps：

Step 201：Terminal determines the quantity N of MAR in the MAR bundled, and determines the first pilot tone according to identified quantity N The length of signal, N are the integer more than 1；

Step 202：Terminal obtains the first pilot signal with the length, and the first pilot signal is placed into binding On MAR；

Step 203：Terminal sends the MAR for the binding that placed the first pilot signal.

Since terminal determines the length of the first pilot signal based on the quantity N of MAR in the MAR of binding, and will have should First pilot signal of length is placed on the MAR of binding, thus multiple MAR in the MAR of binding can be made full use of to be provided On the one hand pilot resources can generate longer pilot signal, provide more pilot signal quantity, and extend pilot signal can Range is selected, on the other hand then enables the network equipment according to being placed on by placing the first pilot signal on the MAR of binding The first pilot signal on the MAR of binding is progressively detected terminal, and then is reached by these two aspects and improve terminal inspection Performance is surveyed, the effect of transmission reliability is enhanced.

Specifically, for step 201, in some embodiments of the invention, terminal can be in the MAR for determining binding After the quantity N of MAR, pilot signal can be placed on the quantity N and each MAR by MAR in the MAR that is bundled determined by calculating Length product, to which the product being calculated to be determined as to the length of the first pilot signal.

Wherein, in the MAR of binding the quantity N of MAR can be defined by standard or can be preconfigured.

For step 202, in some embodiments of the invention, the first pilot signal is being placed into binding by terminal Can be specifically that N number of second pilot signal is first determined according to the first pilot signal, then by this N number of second pilot signal when on MAR It is placed individually on N number of MAR in the MAR of binding.The length of the second pilot signal of each of this N number of second pilot signal is small In or equal to the first pilot signal length.

It is specific for example, Fig. 3 shows in some embodiments of the invention that terminal determines the first pilot signal and by the first pilot tone Signal is placed into the example on the MAR of binding：

As shown in figure 3, the size of MAR is represented by continuous N on frequency domain_RBA RB, each RB occupy N_subA subcarrier And N_symA OFDM symbol shares N_sub×N_symA RE, the wherein N of first row_subA RE is used for putting pilot signal, thus, often The length for the pilot signal that can be placed on a MAR is represented by N_sub；

Assuming that UE1 is transmitted without using the MAR of binding, thus the first pilot signal (P determined by UE1₁) length For N_sub；

UE2 is transmitted using the MAR of binding, and the quantity of MAR is 2 in the MAR of used binding, thus UE2 Identified first pilot signal (P₂) length be 2N_sub；

UE3 is transmitted using the MAR of binding, and the quantity of MAR is 4 in the MAR of used binding, thus UE2 Identified first pilot signal (P₃) length be 4N_sub。

In turn, as shown in figure 3, each terminal will it is respective determined by the first pilot signal be placed into respectively used in When on the MAR of binding：

UE1 can be directly by a length of N_subThe first pilot signal (P₁) be placed on MAR；

UE2 can be by the first pilot signal (P₂) it is divided into a length of N_subTwo sections (being equivalent to 2 the second pilot signals) Afterwards, it is placed individually on 2 MAR in the MAR of binding；

UE3 can be by the first pilot signal (P₃) it is divided into a length of N_subFour sections (being equivalent to 4 the second pilot signals) Afterwards, it is placed individually on 4 MAR in the MAR of binding.

In the example depicted in fig. 3, the first pilot signal is determined using the quantity N of MAR in the MAR of binding due to terminal Length, and the first pilot signal is divided into N number of second pilot signal successively, it is placed individually into each MAR in the MAR of binding On, thus the length of the second pilot signal is equivalent to the length for the pilot signal that can be placed on each MAR.

In some embodiments of the invention, the length of pilot signal can be placed on above-mentioned each MAR, it specifically can be by Terminal is determined according to the size of predefined pilot tone modes of emplacement and each MAR.

As shown in Fig. 4 (a), pilot signal putting on MAR is defined as occupying entire MAR bandwidth and symbol Time, therefore in the example as shown in Fig. 4 (a), the length that pilot signal can be placed on each MAR is N_sub；The example feelings Shape is that the illustrative case of pilot signal is placed on MAR shown in Fig. 3；

As shown in Fig. 4 (b), pilot signal putting on MAR is defined as occupying entirely using a subcarrier as interval The time of MAR bandwidth and a symbol, therefore in the example as shown in Fig. 4 (b), pilot signal can be placed on each MAR Length be N_sub/2；

As shown in Fig. 4 (c), pilot signal putting on MAR is defined as occupying entire MAR bandwidth and two symbols Time, therefore in the example as shown in Fig. 4 (c), the length that pilot signal can be placed on each MAR is 2N_sub；

As shown in Fig. 4 (d), pilot signal putting on MAR is defined as occupying entirely using a subcarrier as interval The time of MAR bandwidth and two symbols, and position is alignment on sub-carriers, therefore in the example as shown in Fig. 4 (d) In, the length that pilot signal can be placed on each MAR is N_sub；

As shown in Fig. 4 (e), pilot signal putting on MAR is defined as occupying entirely using a subcarrier as interval The time of MAR bandwidth and two symbols, and position is staggeredly, therefore in the example as shown in Fig. 4 (e) on sub-carriers In, the length that pilot signal can be placed on each MAR is N_sub；

As shown in Fig. 4 (f), pilot signal putting on MAR is defined as occupying entire MAR bandwidth and two symbols Time, but on two symbol times used in is identical, this is in the example as shown in Fig. 4 (f), on each MAR The length that pilot signal can be placed is N_sub。

It can be seen that after the disposing way of pilot signal determines on each MAR, pilot tone letter can be placed on each MAR Number length just determine therewith.After the length for the pilot signal that can be placed on each MAR is determined, terminal can be as preceding It states described in embodiment, the length of the first pilot signal is determined using the quantity of MAR in the MAR of binding.

It is specific for example, Fig. 5 (a), Fig. 5 (b), Fig. 5 (c) respectively illustrate terminal in some embodiments of the present invention determine it is total Pilot signal length schematic diagram.

As shown in Fig. 5 (a), each MAR of MAR bindings uses different pilot signals, using identical when just passing and retransmitting MAR binding sizes and identical pilot signal.Under this illustrative case, the length of total pilot signal is on each MAR The length L of the pilot signal of placement_MARWith the product of the quantity N of MAR in the MAR of binding.

As shown in Fig. 5 (b), each MAR of MAR bindings uses different pilot signals, using identical when just passing and retransmitting MAR binding sizes and different pilot signals.Under this illustrative case, the length of total pilot signal is on each MAR The length L of the pilot signal of placement_MAR, the quantity N and number of retransmissions N of MAR in the MAR of binding_HARQProduct.

As shown in Fig. 5 (c), each MAR of MAR bindings uses different pilot signals, using difference when just passing and retransmitting MAR binding sizes and different pilot signals.Under this illustrative case, the length of total pilot signal is on each MAR The length L of the pilot signal of placement_MARWith the sum of the quantity of MAR in the MAR that is bundled when each transmission ∑ N_iProduct.

Specifically, in some embodiments of the invention, terminal after the length for determining the first pilot signal, To execute first pilot signal of the acquisition with the length described in step 202.Wherein, the first accessed pilot tone letter Number can be specifically to be based on ZC (Zadoff-Chu) sequence, RM (Reed Muller) sequence, the generations such as Gold sequence.

Further, in some embodiments of the invention, terminal can be according to the first pilot signal got, can be with N number of second pilot signal is determined through but not limited to following manner：

According to the sequence characteristic of the first pilot signal, the first pilot signal is divided into N number of second pilot signal；Alternatively,

First pilot signal is interleaved, and according to the sequence characteristic of the first pilot signal, first after intertexture is led Frequency signal is divided into N number of second pilot signal.

Since terminal is split according to the sequence characteristic of the first pilot signal to obtain N number of second pilot signal, thus put It sets N number of second pilot signal on N number of MAR of binding and is likewise supplied with sequence characteristic, and then the network equipment can be based on sequence Row characteristic carries out progressive terminal detection.

Specifically for example, based on the illustrative case shown by above-mentioned Fig. 5 (a), the length of total pilot signal is on each MAR The length L of the pilot signal of placement_MARWith the product of the quantity N of MAR in the MAR of binding, Fig. 6 (a) and Fig. 6 (b) are respectively illustrated Terminal determines the schematic diagram of N number of second pilot signal in some embodiments of the present invention.Wherein, shown in Fig. 6 (a) and Fig. 6 (b) In the example gone out, identical pilot signal placed on the MAR for the binding for just passing and retransmitting：

As shown in Fig. 6 (a), accessed total pilot signal can be divided into N number of a length of L by terminal in order_MARLead Frequency division group (is equivalent to the first pilot signal being divided into N number of second pilot signal), and then can be by this N number of pilot packet successively It is placed on each MAR in the MAR of binding；

As shown in Fig. 6 (b), terminal can will interweave in order by accessed total pilot signal after intertexture Total pilot signal afterwards is divided into N number of a length of L_MARPilot packet (be equivalent to and the first pilot signal after intertexture be divided into N A second pilot signal), and then this N number of pilot packet can be sequentially placed on each MAR in the MAR of binding.

Specifically, total pilot signal can be based on ZC (Zadoff-Chu) sequence, RM (Reed Muller) sequence, The generations such as Gold sequence.Have Nested property based on the Delsarte-Goethals set RM sequences generated, thus, pass through connection Pilot resources when MAR and the re-transmission using binding are closed, short pilots are merged and generate long pilot tone, long pilot tone also corresponds to RM sequences Definition so that the network equipment can carry out progressive detection.

Below to generate total pilot signal based on RM sequences as an example, describing terminal in some embodiments of the present invention Obtain the process of total pilot signal：

Firstly the need of the length of the total pilot signal of determination.With reference to the foregoing embodiments, if pilot signal on each MAR Disposing way determines, then the pilot length L on each MAR_MARIt determines therewith, considers following three kinds of situations：

1, terminal does not use the MAR of binding to be transmitted, number of retransmissions N_HARQIt determines, retransmits and believed using different pilot tones Number, thus the length of total pilot signal is L_MAR×N_HARQ；

2, terminal is transmitted using the MAR of binding, does not consider to retransmit, thus the length of total pilot signal is L_MAR× N_MAR；

3, terminal is transmitted using the MAR of binding, and each MAR in the MAR of binding uses different pilot signals, weight Bundle size NMAR and different pilot signals using identical MAR when biography, total pilot length be thus total pilot signal Length is L_MAR×N_MAR×N_HARQ。

After the length for determining total pilot signal, since the length of original RM sequences is 2^m, m is positive integer, it is therefore desirable to Pilot sequence length and transmission mode according to actual needs carries out equitable subsection to RM sequences, forms corresponding short sequence.

By taking said circumstances 1 as an example, the segmentation method of RM sequences is illustrated.

Total pilot sequence length is L_MAR×N_HARQ, required RM sequence lengths are 2^m, the value of m is by specific segmentation method It determines.Segmentation method includes but not limited to following two modes：

Segmentation method 1：Discrete method at equal intervals

By 2^mLong RM sequences are divided into N_HARQSection, wherein m are to meet 2^m<L_MAR×N_HARQMaximum m values.By what is obtained N_HARQThe short sequence of section is L respectively_MARThe Fast Fourier Transform (Fast Fourier Transformation, FFT) of points, obtains To N_HARQSection L_MARThe short sequence of length is orderly used to and just passes and retransmit, and it is L to form total length_MAR×N_HARQPilot tone；

Segmentation method 2：Unequal interval discrete method

It uses in the method for 2 power side's Length discrepancy segmentation, i.e., long sequence is segmented into length successively from front to back is N_HARQA short sequence.First segment for just pass, it is subsequent segmentation according to It is secondary to be used to retransmit.Such as with N_HARQTo be illustrated respectively for 2 and 4：

Work as N_HARQWhen=2, it is 2 that sequence order, which is divided into length,^m-1With 2^m-1Two sections, wherein first segment is for just passing, the Two sections for retransmitting.First segment short pilots and second segment short pilots can be merged into long pilot frequency sequence when re-transmission and carry out user's inspection It surveys.Because RM sequences have nested properties, short sequence and long sequence meet RM sequence definitions at this time, and the long sequence after merging increases The strong detection performance of user.Work as N_HARQWhen=4, it is 2 that sequence order, which is divided into length,^m-3, 2^m-3, 2^m-2With 2^m-1Four sections, Middle first segment for just passing, behind three sections for retransmitting, the short sequence that often retransmitting can once transmit with front merges structure Enhance detection at longer RM sequences.

It need to meet after segmentation that a longest segment length need to be less than L in short sequence for the determination of m values_MAR, that is, find satisfaction 2^m-1<L_MARMaximum m values.Then L is done to short sequence each of after segmentation_MARThe FFT of length points, generating total length is L_MAR×N_HARQPilot tone.

For situation 2,3, method similar to the above can be taken to generate pilot frequency sequence, and do Length discrepancy segmentation and constitute short-range missile Frequency just pass, and retransmits, and progressive detection is realized using sequence characteristic.

In some embodiments of the invention, the first pilot signal is placed on the MAR of binding by terminal by step 202 Later, the MAR that can send the binding that placed the first pilot signal described in step 203 is just executed.

Specifically, terminal places transferring content in running time-frequency resource, and transferring content includes the first pilot signal and waits for The data etc. of transmission.For example, being based on above-mentioned illustrative case illustrated in fig. 3, Fig. 7 shows in some embodiments of the present invention and ties The N number of MAR tied up occupies the schematic diagram of running time-frequency resource.

As shown in fig. 7, UE1 is transmitted without using the MAR of binding, the MAR transmitted occupies resource block 22；UE2 is used 2 MAR of binding are transmitted, and occupy resource block 11,33 respectively；UE3 is transmitted using 4 MAR of binding, is occupied respectively Resource block 31,32,33,34.Wherein UE2 and UE3 collides on resource block 33.

Further, terminal can also place transferring content in many ways, that is, occupancy of the MAR bundled to running time-frequency resource There are many modes.Such as by taking UE2 in such as Fig. 3 as an example, Fig. 8 (a), Fig. 8 (b), Fig. 8 (c), Fig. 8 (d), Fig. 8 (e), Fig. 8 (f) are respectively Show that terminal in some embodiments of the present invention places the schematic diagram of transferring content in running time-frequency resource：

As shown in Fig. 8 (a), information to be transmitted can be placed on that frequency domain is identical by UE2, on the MAR of Time Continuous；

As shown in Fig. 8 (b), it is identical that information to be transmitted can be placed on frequency domain by UE2, on time discontinuous MAR；

As shown in Fig. 8 (c), it is continuous that information to be transmitted can be placed on frequency domain by UE2, on time identical MAR；

As shown in Fig. 8 (d), it is discontinuous that information to be transmitted can be placed on frequency domain by UE2, on time identical MAR；

As shown in Fig. 8 (e), information to be transmitted can be placed on frequency domain and differed by UE2, on the MAR of Time Continuous；

As shown in Fig. 8 (f), information to be transmitted can be placed on frequency domain and differed by UE2, on time discontinuous MAR.

Specifically, in some embodiments of the invention, believed according to the pilot tone on the MAR of binding to simplify the network equipment Number carry out terminal detection when complexity, in end side, the occupied running time-frequency resource positions MAR of binding can be pre-configured with The MAR with the binding in the corresponding running time-frequency resource positions the quantity N of MAR set in choose.

It can be seen that the scheme for uplink transmission that the embodiment of the present invention is provided mainly utilizes bundle by combining The MAR tied up in a disguised form uses longer pilot signal so that possess progressive detection performance in the network equipment, exempt to authorize to enhance The terminal detection performance of access system.Wherein, terminal can be by bundling the size of MAR, and can further pass through re-transmission time Number determines long pilot signal (above-mentioned first pilot signal) length, and long pilot signal can be blocked by blocking after intertexture Method generates short pilots signal (above-mentioned second pilot signal), so that the network equipment can merge short pilots signal one by one To carry out terminal detection after long pilot signal, the length of longer pilot signal enhances the detection performance of user, and can carry For more pilot signal quantity.

Fig. 9 shows the method flow diagram for uplink transmission that the other embodiment of the present invention is provided.Such as Flow shown in Fig. 9 can be realized by the network equipment.For example, can be configured with to execute such as on the network equipment 101 as shown in Figure 1 The function module of flow shown in Fig. 9, the function module to execute the flow can be by hardware, software programming or software and hardware It is implemented in combination with.

As shown in figure 9, the flow includes the following steps：

Step 901：The network equipment receives the MAR of the binding of terminal transmission, and the first pilot tone letter is placed on the MAR of the binding Number；The length of first pilot signal is terminal in the MAR for determining the binding after the quantity N of MAR, according to identified quantity N Determining, N is the integer more than 1；

Step 902：The network equipment is according to the first pilot signal placed on the MAR of the binding, detection terminal.

Specifically, it is placed with N number of second pilot signal respectively on N number of MAR in the MAR of binding, this N number of second pilot tone letter Number is determined according to the first pilot signal for terminal, the length of the length of the second pilot signal less than or equal to first pilot signal Degree.

In some embodiments of the invention, this N number of second pilot signal can be sequence of the terminal according to the first pilot signal Characteristic, the first pilot signal is N number of obtains for segmentation；Alternatively, this N number of second pilot signal can be that terminal believes the first pilot tone It number is interleaved, and according to the sequence characteristic of the first pilot signal, the first pilot signal after segmentation interweaves N number of obtains.

In some embodiments of the invention, the length of the first pilot signal can be terminal by identified quantity N with it is each The product that the upper length that can place pilot signal of MAR is multiplied.

In some embodiments of the invention, can be placed on each MAR pilot signal length be terminal according to predefined What the size of pilot tone modes of emplacement and each MAR determined.

Specifically, terminal determines the first pilot signal length, obtains the first pilot tone in some embodiments of above-mentioned present aspect The process of signal and determining second pilot signal specifically may refer to present invention side described in end side Method flow example, the application will not be described in great detail herein.

In some embodiments of the invention, network equipment detection terminal can be specifically each in the MAR for obtain binding The second pilot signal placed on MAR, and in one the second pilot signal of every acquisition, currently get all second are led After frequency signal merges, detection terminal.

Specifically, if the network equipment determines the initial position for the running time-frequency resource that the MAR of binding is occupied, the network equipment It can be from the second pilot signal placed on each MAR in the MAR that the initial position obtains the binding successively；Otherwise, network is set In the standby MAR that can attempt the acquisition binding on all possible position of the MAR of the binding running time-frequency resources occupied one by one The second pilot signal placed on each MAR.

Specifically, the network equipment can attempt the quantity of MAR in the MAR of all possible binding one by one, and taste every time Above-mentioned progressive detection process is executed in examination, until detecting that terminal or detection are completed.

In some embodiments of the invention, in end side, the occupied running time-frequency resource positions MAR of binding can be pre- It is chosen in the set of the corresponding running time-frequency resource positions the quantity N of MAR in the MAR with the binding first configured, and then network is set The standby frequency resource position that can be occupied according to the MAR of received binding, determines the quantity N of MAR in the MAR of binding, To simplify the complexity that the network equipment carries out terminal detection.

In some embodiments of the invention, the network equipment can determine that terminal may pass by agreement or semi-persistent scheduling Defeated position, and then the pilot signal placed on the MAR of the binding received directly can be merged progress terminal by the network equipment Detection.
