Background
In order to further improve the network transmission speed, improve the user experience, and be suitable for the wireless communication service of the large-scale internet of things, research on the fifth generation mobile communication technology (5G) is being widely performed.
Future 5G applications will cover three broad categories of scenarios: enhanced Mobile broadband (eMBB), Ultra-Reliable Low Latency Communication (URLLC), and Mass Machine Type Communication (mMTC). The eMBB scene refers to further improvement of performance such as user experience on the basis of the existing mobile broadband service scene. For example, the eMBB can be applied to large-flow mobile broadband services such as 3D or ultra-high definition video; the mMTC can be applied to large-scale Internet of things services; the URLLC can be applied to services which need low time delay and high reliable connection, such as unmanned driving, industrial automation and the like.
For URLLC traffic, there are two basic requirements: firstly, the higher delay requirement brought by service emergency, for example, the delay of the uplink and downlink user plane specified at present cannot exceed 0.5 ms; secondly, the requirement on reliability is high, for example, the error rate within 1ms cannot exceed 0.001%. If time division multiplexing is performed on resources of the eMBB service and the URLLC service, the time delay of the URLLC service is longer; if frequency division multiplexing is performed on the resources of the eBB service and the URLLC service, when there is no URLLC service, the frequency band allocated to the URLLC service cannot be used for data transmission of the eBB service, resulting in low resource utilization efficiency.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings.
In order to meet uplink transmission requirements of various services while ensuring the utilization efficiency of resources, embodiments of the present invention provide an uplink transmission method.
Referring to fig. 1, a schematic flow chart of an uplink transmission method provided in an embodiment of the present invention is shown, where as shown in the drawing, the method includes the following steps:
step 101, the network device sends first indication information to the terminal device.
When the terminal equipment needs to carry out uplink transmission, the network equipment schedules scheduling resources for carrying out uplink transmission for the terminal equipment and informs the terminal equipment through the first indication information. Optionally, the first indication information may be physical downlink control information, that is, the network device may indicate the resource for uplink transmission to the terminal device through the dynamic physical downlink control information, or the network device may indicate the resource for uplink transmission to the terminal device through the semi-persistent scheduling physical downlink control information, or the network device may pre-configure the resource for uplink transmission for the terminal device through the first indication information.
And 102, the terminal equipment determines scheduling resources according to the first indication information.
After receiving the first indication information sent by the network device, the terminal device determines scheduling resources for uplink transmission allocated to the terminal device by the network device according to the first indication information. Optionally, the first indication information includes information of a size and a position of a physical resource block of the scheduling resource.
And 103, the terminal equipment preprocesses the uplink information.
Optionally, the uplink information includes uplink service information, or uplink control information, or uplink service information and uplink control information.
Optionally, the preprocessing process includes a channel coding process. Because there are interference and signal attenuation during communication, errors may occur during signal transmission, so error correction and error detection techniques, i.e. error correction and error detection coding techniques, are usually applied to digital signals to enhance the capability of resisting various interferences during signal transmission in a channel, thereby improving the reliability of the system. Specifically, the sending end may add redundant data to the original data to be sent, where the redundant information is related to the original data; the receiving end can detect and correct the received data according to the correlation between the redundant data and the original data. For example, the terminal device may use a Low Density Parity Check Code (LDPC) or a Polar Code to perform channel coding on the uplink information. As another example, if the uplink information includes uplink trafficIf the information is received, the terminal equipment adopts LDPC codes to perform channel coding on the uplink information; and if the uplink information only comprises the uplink control information and does not comprise the uplink service information, the terminal equipment adopts Polar codes to carry out channel coding on the uplink information. For example, the information generated by the terminal device after performing channel coding on the uplink information is b (0)bit-1) wherein MbitIs the number of bits after channel coding the uplink information.
Optionally, after performing channel coding on the uplink information to be transmitted, the terminal device may further perform other preprocessing processes on the uplink information after the channel coding. Taking the uplink waveform sent by the terminal device as a Single-carrier Frequency-Division Multiple Access (SC-FDMA) signal as an example, other preprocessing processes performed by the terminal device on the channel-coded uplink information may be as shown in fig. 2.
Scrambling (Scrambling): in uplink transmission, each terminal device uses its dedicated scrambling sequence to scramble the channel-coded uplink information. For example, information b (0) generated by channel coding the uplink informationbit-1) the information after scrambling is
Figure BDA0001217450640000101
Modulation (Modulation): the scrambled uplink information is processed
Figure BDA0001217450640000102
Performing digital modulation, such as QPSK modulation and 16QAM modulation, to obtain a complex symbol d (0)symb-1), wherein MsymbIndicating the number of bits after modulating the uplink information.
Transform precoding (Transform Precoder): the precoding type (discrete fourier transform DFT type and length) is dynamically determined from different input lengths.
M after digital modulationsymbThe symbols are divided into P groups, the digitally modulated symbol in each group corresponds to an SC-FDMA symbol in the scheduling resource, and the digitally modulated symbol for each groupThe number is subjected to DFT transform processing. After the conversion pre-coding processing, the information z after the conversion pre-coding is output corresponding to the SC-FDMA symbol uu(0),...,zu(Mu-1). The DFT-converted uplink information included on the symbol u is MuA symbol.
Physical Resource mapping (Resource Element Mapper): and mapping the information subjected to conversion precoding processing in each group to each SC-FDMA symbol of scheduling resources, wherein the mapping is carried out firstly in a frequency domain and then in a time domain. After physical resource mapping, the terminal device determines a corresponding relationship between a data block of the SC-FDMA signal and all or part of scheduling resources, that is, determines a data block to be transmitted on each resource block. Specifically, the modulated complex symbols respectively correspond to resources other than the resource for the terminal device to send the DeModulation Reference Signal (DMRS) in the scheduling resources, and each resource unit corresponds to one modulated complex symbol. For example, what is shown in fig. 3 is a corresponding relationship between the scheduling resource and the preprocessed uplink information. The uplink information and the uplink resources after the preprocessing process meet the preset corresponding relationship. For example, the uplink information z after the terminal device has undergone the conversion pre-coding process0(0) And the resource with the lowest frequency on the symbol 0 in the scheduling resources. Uplink information z after conversion precoding processing of terminal equipment0(1) Corresponding to the second lowest frequency resource on symbol 0 in the scheduling resources, etc.
SC-FDMA signal generation (SC-FDMA signal gen): and on each SC-FDMA symbol, the terminal equipment converts the information of the conversion precoding processing mapped on each SC-FDMA symbol into an SC-FDMA signal in an SC-FDMA signal generation mode.
It should be noted that the preprocessing process shown in fig. 2 is only one embodiment of the present application, and the preprocessing process may only include a part of the process shown in fig. 2, and may also include a process not shown in fig. 2, which is not limited in this application.
And step 104, the terminal equipment sends the first information on the first resource. The first information is all or part of the preprocessed uplink information, and the first resource is a resource except the second resource and/or the third resource in the scheduling resources.
The second resource comprises an intersection of the scheduling resource and the resource indicated by the second indication information, namely a first overlapped resource; the second indication information is indication information used for indicating resources and received by the terminal device before preprocessing the uplink information. Optionally, the second information may be information received by the terminal device through a higher layer signaling, for example, Radio Resource Control (RRC) information or information in Medium Access Control (MAC).
The third resource comprises an intersection of the scheduling resource and the resource indicated by the third indication information, namely a second overlapping resource; the third indication information is indication information for indicating resources received by the terminal device after or during the preprocessing of the uplink information. Optionally, the third indication information is information received by the terminal device through a physical downlink control channel or information obtained by the terminal device through detecting signals sent by other terminal devices.
When the terminal device executes the step 104, if the first resource is a resource except the second resource in the scheduling resource, the first information is all preprocessed uplink information; if the first resource is a resource except the third resource in the scheduling, the first information is preprocessed uplink information except information corresponding to the third resource in the preprocessed uplink information; and if the first resource is a resource except the second resource and the third resource in the scheduling, the first information is preprocessed uplink information except information corresponding to the third resource in the preprocessed uplink information.
Optionally, the first information is information corresponding to the first resource, which is determined according to a preset rule; when the first resource is a resource except the second resource in the scheduling resources, or when the first resource is a resource except the second resource and the third resource in the scheduling resources, the preset rule is a corresponding relationship between the preprocessed uplink information and the resource except the second resource in the scheduling resources; and when the first resource is a resource except a third resource in the scheduling resources, the preset rule is a corresponding relation between the preprocessed uplink information and the scheduling resources.
Optionally, if the terminal device generates an SC-FDMA signal in the preprocessing process, the terminal device uses the SC-FDMA signal to send the first information on the first resource when performing step 104, that is, the first information is an SC-FDMA signal corresponding to the first resource after resource mapping. Of course, the terminal device may also generate signals of other waveforms and send the signals to the network device, which is not limited in this embodiment of the present invention.
And 105, the network equipment receives the uplink information preprocessed by the terminal equipment on the first resource and carries out reverse preprocessing.
The network equipment receives the uplink information preprocessed by the terminal equipment on the first resource, and after reverse preprocessing, the process of reverse preprocessing corresponds to each process of preprocessing the uplink information by the terminal equipment. And the network equipment obtains the uplink information sent by the terminal equipment according to the uplink information.
In some embodiments, before performing the preprocessing on the uplink information in step 103, the terminal device may further receive second indication information sent by the network device, where the second indication information is used to instruct the terminal device to avoid the resource indicated by the second indication information, that is, not perform uplink transmission on the resource indicated by the second indication information. For example, the network device may reserve part of resources for data transmission of the URLLC service, and therefore the network device may notify the terminal device performing other service transmission through the second indication information that uplink transmission is not performed on the reserved resources.
The terminal device may determine the second resource according to the resource indicated by the second indication information and the scheduling resource, where the second resource includes an intersection between the resource indicated by the second indication information and the scheduling resource indicated by the first indication information, that is, a first overlapping resource, as shown in fig. 4. In this case, the terminal device may not consider the second resource when performing the preprocessing. For example, when the terminal device performs channel coding on the uplink information, the code rate of the channel coding may correspond to the number of the uplink information and resources except the second resource in the scheduling resources. And when the terminal equipment maps the uplink information after the preprocessing process to the uplink resource, the uplink information after the body preprocessing on the second resource and the like are not considered.
Specifically, the terminal device obtains an indication that the second resource cannot be used for transmitting the uplink information before preprocessing the uplink information, that is, the first resource does not include the second resource in the scheduling resources. Then, the terminal device needs to exclude the second resource when preprocessing the uplink information. For example, when the terminal device performs channel coding on the uplink information, it needs to determine a coding rate of the channel coding, where the coding rate is a ratio of a data amount of the uplink information to be transmitted to a data amount of the uplink information after the channel coding. The data size of the uplink information after channel coding is limited by the size of the resource that can be used when the terminal device performs uplink transmission. Therefore, after the terminal device determines the second resource according to the second indication information sent by the network device before performing channel coding, when the terminal device determines the code rate of the channel coding, the second resource needs to be excluded from the uplink transmission resources available to the terminal device, that is, the code rate of the channel coding corresponds to the number of the uplink information and the resources except the second resource in the scheduling resources. In this way, the information corresponding to the second resource does not exist in the preprocessed uplink information.
In some other embodiments, after the terminal device performs the preprocessing on the uplink information or during the terminal device performs the preprocessing on the uplink information, the terminal device may further receive third indication information sent by the network device or another terminal device, where the third indication information is also used to indicate the terminal device to avoid the resource indicated by the third indication information, and perform no uplink transmission on the resource indicated by the third indication information, that is, the first resource does not include the third resource. For example, terminal device a is performing uplink transmission of an eMBB service on a resource scheduled by the network device, at this time, terminal device B needs to perform uplink transmission of a URLLC service, the network device allocates a scheduling resource to terminal device B, and there is an overlapping portion between the scheduling resource allocated to terminal device B and the scheduling resource allocated to terminal device a, in order to ensure the requirement of the URLLC service for data transmission, terminal device a needs to avoid, and uplink transmission is not performed on the resource of the overlapping portion, so that data transmission of terminal device a and terminal device B is not affected due to collision.
The terminal device may determine the third resource according to the resource indicated by the third indication information and the scheduling resource, where the third resource includes an intersection between the resource indicated by the third indication information and the scheduling resource indicated by the first indication information, that is, a second overlapping resource, as shown in fig. 4.
Since the third indication information is the indication information received by the terminal device after the preprocessing or during the processing, the terminal device is instructed to avoid the resource indicated by the third indication information, and the terminal device may have started or completed the channel coding process. The terminal device does not exclude the third resource when performing channel coding on the uplink information, that is, the terminal device considers that the third resource can be used for sending the preprocessed uplink information when performing channel coding. In this way, the information corresponding to the third resource through the preset rule exists in the preprocessed uplink information.
In some embodiments, the terminal device receives the second indication information sent by the network device before performing the preprocessing in step 103; meanwhile, after or during the preprocessing, the terminal device receives third indication information sent by the network device or other terminal devices, that is, the first resource is a resource other than the second resource and the third resource in the scheduling resources.
For example, before the terminal device performs the preprocessing on the uplink information, the second resource determined according to the second indication information is 12 resource units with the lowest frequency positions on the last symbol and the last but one symbol in the scheduling resource, as shown in fig. 5, when determining the coding rate of the channel coding in the preprocessing process, the terminal device does not consider the second resource. Accordingly, in the process of processing the physical resource mapping, the terminal device should start from the 13 th resource unit on the last symbol and the last but one symbol when mapping the information after the precoding processing on the last symbol and the last but one symbol, as shown in fig. 5. Terminal equipment is in pair uplinkAfter information is preprocessed or during the preprocessing, third indication information is received, the third resource determined according to the third indication information is 12 resource units of frequency positions 13-24 on symbol 5 and symbol 6 in the scheduling resource, and the preprocessed uplink information already includes information corresponding to the third resource, such as z in fig. 54(12)z,4(13),z.4.., and (z 2)53(1)2),z5(13),...,z5(23)。
In the embodiment shown in fig. 5, if the first resource is a resource other than the third resource in the scheduling resources, or the first resource is a resource other than the second resource and the third resource in the scheduling resources, the terminal device does not transmit uplink information on the third resource when transmitting the uplink information in order to avoid collision with information transmitted by other terminal devices, so that the single carrier characteristic of the uplink information transmitted by other resources on a symbol where the third resource is located may be damaged.
As shown in fig. 6, it is assumed that the scheduling Resource includes 10 Resource Blocks (RBs) in the frequency domain, and a Cubic Metric (CM) value of information corresponding to the scheduling Resource on the Y-th symbol in the preprocessed uplink information is 1.26. If the third resource includes one RB in the scheduling resource on the Y-th symbol, and there is information corresponding to the third resource in the preprocessed uplink information according to the above embodiment, the terminal device does not send the preprocessed uplink information corresponding to the third resource, but only sends the preprocessed information corresponding to other RBs on the symbol, the CM value of the information sent on the symbol is increased (about 1.5), and the transmission efficiency is decreased; if the terminal equipment only sends the uplink information which is correspondingly preprocessed on fewer RBs, the CM value of the sent signal is continuously increased, and the transmission efficiency is continuously reduced; if the terminal device transmits the preprocessed uplink information only on 1 RB, the CM value of the transmitted signal is as high as about 3.7, and the transmission efficiency is very low.
Still taking fig. 5 as an example, the preprocessed uplink information satisfies the single carrier characteristic on each symbol, but the preprocessed uplink information eventually satisfies the single carrier characteristicAfter the end device determines the third resource, if the terminal device does not transmit uplink information corresponding to the third resource on the symbol 5 and the symbol 6, z transmitted on the symbol 5 will be caused to be4(0),z4(1),...,z4(11) And z4(24),z4(25),...,z4(M4-1), and z transmitted on symbol 65(0),z5(1),...,z5(11) And z5(24),z5(25),...,z5(M5-1) the single carrier characteristic is not satisfied, which in turn leads to a reduction of the transmission efficiency of the terminal device on symbols 5, 6.
In order to avoid the foregoing problem, in a possible implementation manner of the embodiment of the present invention, the determining, by the terminal device, the third resource may further include, in addition to the second overlapping resource: a resource located on the same time domain symbol as the second overlapping resource and a scheduling resource, other than the second overlapping resource. I.e. the third resource comprises all resources in the scheduled resource that are located on the same time domain symbol as the second overlapping resource, as shown in fig. 7. Thus, the first resource does not include all resources that are located on the same time domain symbol as the second overlapping resource. The terminal device does not send the preprocessed uplink information corresponding to the third resource on the first resource.
To avoid the above problem, another possible implementation manner in the embodiment of the present invention is as follows. According to the above description of the embodiment, the preprocessed uplink information has information corresponding to the third resource. The terminal equipment does not send the preprocessed uplink information corresponding to the third resource but only sends other preprocessed information on the symbol, and the information does not meet the single carrier characteristic. To avoid secondary effects, the terminal device may truncate the uplink information before the DFT transform on the symbol, and re-perform the DFT transform on the remaining uplink information after the truncation. Thus, the single carrier characteristic of the information sent by other resources on the symbol after preprocessing can be ensured.
Still taking fig. 5 as an example, if z is sent directly on symbol 54(0),z4(1),...,z4(11)z4(24),z4(25),...,z4(M41), the transmission efficiency of the terminal equipment on the symbols 5 and 6 is reduced because the signals do not meet the single carrier characteristic. To solve this problem, the terminal device may transmit z on symbol 54(0),z4(1),...,z4(11) And z4(24),z4(25),...,z4(M4Re-performing the DFT conversion on the information before the DFT conversion corresponding to a part of the information in the step-1). The uplink information after the DFT conversion is re-performed can satisfy the single carrier characteristic. In this way, the terminal device does not send the preprocessed uplink information corresponding to the third resource on the first resource, but sends the uplink information after performing DFT conversion again on the symbol where the third resource is located, and the information satisfies the single carrier characteristic, so that the problem that the transmission efficiency of the terminal device on the symbol 5 is reduced can be solved. For example, the DFT-converted uplink information z corresponding to the resource on symbol 54(0),z4(1),...,z4(M4-1) d before DFT transformation4(0),d4(1),...,d4(M4-1); the terminal equipment can pair d according to the size of the resources available on the symbol 5 except the third resource4(0),d4(1),...,d4(M4The partial information in-1) re-performs DFT conversion, and the terminal device transmits the uplink information on the symbol 5 after the DFT conversion is performed again, so that the uplink information transmitted on the symbol 5 by the terminal device satisfies the single carrier characteristic.
However, considering the cost of the terminal device, the terminal device does not usually support discrete fourier transform of all points. Scheduling resources on the symbol where the third resource is located except for the resource of the third resource on the symbol, the number of remaining resources may not match the number of points of DFT conversion supported by the terminal device. For example, the scheduling resource is 15 RBs, and the third resource includes a width of 2 RBs each on the sixth and seventh symbols, and the remaining resources except for the third resource are a width of 13 RBs on the sixth and seventh symbols. According to the above description of the embodiments, the terminal device needs to transmit the preprocessed uplink information corresponding to the resources except the third resource in the scheduling resources on the symbol, that is, 13 uplink information are transmittedAnd the DFT conversion is carried out again on the uplink information corresponding to the RB. However, the terminal device may perform DFT change on the uplink information corresponding to Q RBs in a normal case, wherein,
Figure BDA0001217450640000141
α2、α3and alpha5All are non-negative integers, however, 13 obviously does not belong to the value range of Q, i.e. exceeds the capability range of the terminal device. Therefore, a possible implementation method is that the third resource includes 1 RB in addition to the second overlapping resource, so that the number of remaining resources in the scheduling resource except the third resource can satisfy the value range of Q on the symbol where the third resource is located, that is, the number of remaining resources is matched with the number of DFT conversion points supported by the terminal device.
Therefore, the third resource determined by the terminal device may include, in addition to the second overlapping resource: n (J) Resource Elements (REs) (or RBs) adjacent to the second overlapping Resource on a jth time domain symbol in the second overlapping Resource, wherein J ∈ [1, J ], J denotes a number of time domain symbols included in the second overlapping Resource, n (J) is a minimum value satisfying n (J) ═ k (J) -l (J) -Q, where Q is a value satisfying a number of points of the terminal device to DFT, k (J) denotes a number of REs (or RBs) included on the jth time domain symbol of the scheduled Resource, and l (J) denotes a number of REs (or RBs) included on the jth time domain symbol of the second overlapping Resource. In addition, since n (i) is the minimum value satisfying n (i) ═ k (i) — l (i) — Q, the first resource left to the terminal device is increased, and the utilization efficiency of the resource can be further ensured. However, in actual application, the value of n (i) may be adjusted according to different scene requirements, for example, the maximum value of n (i) satisfying n (i) ═ k (i) -l (i) -Q, or others may be adopted for n (i). If the number of REs (or RBs) contained in each time domain symbol of the second overlapping resource is equal, the obtained values of N (j) are the same; however, in some embodiments, the number of REs (or RBs) included in each time domain symbol of the second overlapping resource is not equal, and the obtained values of n (j) may be different.
In the above embodiment, if the first resource is a resource other than the second resource in the scheduling resource, or the first resource is a resource other than the second resource and the third resource in the scheduling resource, the preprocessed uplink information does not include information corresponding to the second resource. The terminal equipment needs to perform a conversion pre-coding process on information corresponding to other resources on the symbol where the second resource is located. Taking the conversion pre-coding process as DFT for example, considering the cost problem of the terminal device, the terminal device usually does not support DFT of all points; on the symbol where the second resource is located, the number of remaining resources in the scheduling resource except the second resource may not match the number of DFT conversion points supported by the terminal device.
For example, the scheduling resource is 8 RBs, and the second resource includes 1 RB each on symbols 4, 5, then the remaining resources on symbols 4, 5 except for the second resource are 7 RBs. According to the above description of the embodiment, the information corresponding to the second resource does not exist in the uplink information preprocessed by the terminal device. The terminal device needs to perform DFT on the preprocessed uplink information corresponding to the resources except the second resource in the transmission scheduling resources on the symbol, that is, the uplink information corresponding to the 7 RBs, however, the terminal device may not support DFT with the number of subcarriers included in the 7 RBs. Therefore, one possible implementation manner is that the second resource includes 1 RB in addition to the first overlapping resource, so that the number of remaining resources of the scheduling resource on the symbol where the second resource is located, in addition to the resource of the second resource on the symbol, matches the number of points of DFT conversion supported by the terminal device. That is, the second resources further include n (i) REs adjacent to the first overlapping resource or n (i) RBs adjacent to the first overlapping resource on the ith time domain symbol of the first overlapping resource. Wherein I ∈ [1, I ∈ ]]I denotes the number of time domain symbols included in the first overlapping resource, n (I) is a minimum value satisfying n (I) ═ k (I) -l (I) -Q, Q is a value satisfying the number of points of the terminal device to the discrete fourier transform DFT, k (I) denotes the number of REs (or RBs) included on the I-th time domain symbol of the scheduled resource, and l (I) denotes the number of REs (or RBs) included on the I-th time domain symbol of the first overlapping resource. In general, Q is such that
Figure BDA0001217450640000142
A value of (a), wherein2、α3And alpha5Are all non-negative integers. As shown in fig. 8, on the 1 st time domain symbol (i.e. time domain symbol 5) corresponding to the first overlapping resource, the scheduling resource includes K (1) ═ 12 REs on the time domain symbol, and the first overlapping resource includes l (i) ═ 5 REs on the time domain symbol, at this time, 7 REs remain on the time domain symbol 5, and 7 cannot satisfy
Figure BDA0001217450640000151
Therefore, N cannot be 0; when N is 1, Q is 6, 6 can satisfy
Figure BDA0001217450640000152
Namely alpha2＝1，α3＝1，α5N is 0, so N is 1, which is the minimum value that satisfies the condition. In the case shown in fig. 8, the l (i) values of the first overlapping resource on the 1 st time domain symbol and the 2 nd time domain symbol are equal, so the obtained N values are the same; however, in some embodiments, the values of l (i) of the first overlapping resource may not be equal in different time domain symbols, and thus the obtained values of N may also be different.
In addition, since n (i) is the minimum value satisfying n (i) ═ k (i) — l (i) — Q, the first resource left to the terminal device is increased, and the utilization efficiency of the resource can be further ensured. However, in actual application, the value of n (i) may be adjusted according to different scene requirements, for example, the maximum value of n (i) satisfying n (i) ═ k (i) -l (i) -Q, or others may be adopted for n (i).
In another possible implementation manner, to avoid a problem that the number of remaining resources of the scheduling resource on the symbol where the second resource is located may not match the number of DFT (DFT) transformed points supported by the terminal device except for the resource of the second resource on the symbol, the second resource determined by the terminal device may include, in addition to the first overlapping resource, a resource located on the same time domain symbol as the first overlapping resource and an intersection of the scheduling resource, and other resources except the first overlapping resource, that is, the second resource, included in the scheduling resource and all resources located on the same time domain symbol as the first overlapping resource, as shown in fig. 9.
For the process of determining the second resource and the third resource, the embodiment of the present invention provides the following determination method: the method includes only the overlapping resources, or includes all resources on a time domain symbol corresponding to the overlapping resources in the scheduling resources, or includes the overlapping resources and N REs or RBs adjacent to the overlapping resources in the frequency domain in the scheduling resources. In a specific implementation, any one of the above methods may be used when determining the second resource; when determining the third resource, any one of the above methods may also be used, which is not limited in this embodiment of the present invention. For ease of understanding, the following description will be made in terms of several specific embodiments.

Of course, in addition to the situations shown in the above embodiments, other combinations may also be obtained by applying the method for determining the second resource and the third resource provided in the embodiments of the present invention, and no example is given here.
In step 104, if the first resource determined by the terminal device is the scheduling resource excluding the third resource, or the scheduling resource excluding the second resource and the third resource, a possible implementation manner is that the terminal device does not transmit uplink information corresponding to the third resource on the third resource, so as to avoid information collision with information sent by other terminal devices.
Due to the fact thatRedundant information exists in the uplink information after channel coding, so that the network equipment can check and correct the received uplink information. Therefore, in some cases, the network device may decode the correct uplink information even if the terminal device does not transmit the uplink information corresponding to the third resource. However, in some cases, for example, the amount of information corresponding to the third resource is large, the amount of the preprocessed uplink information that is not received by the network device is large, and the preprocessed uplink information cannot be decoded correctly, and at this time, the terminal device may send the preprocessed uplink information corresponding to the third resource on the fourth resource. The fourth resource may be a resource indicated to the terminal device by the network device through the fourth indication information, or a resource corresponding to the third resource through a preset rule. For example, the preset rule may use, as the fourth resource, a resource after M time domain symbols, or M subframes, or M slots after the resource is scheduled. In the embodiment shown in fig. 5, the terminal device does not transmit z on the third resource4(12),z4(13),...,z4(23) And z5(12),z5(13),...,z5(23) However, the terminal device may transmit z on the fourth resource4(12),z4(13),...,z4(23) And z5(12),z5(13),...,z5(23)。
Optionally, if the third indication information is not sent to the terminal device by the network device, but the terminal device obtains the third indication information by detecting information sent by other terminal devices, the network device does not know that the resource for sending the uplink information by the terminal does not include the third resource, and erroneously demodulates and decodes the information received on the third resource and the resource received on the other resource, which may cause the network device to fail to correctly obtain the uplink information. To avoid this, one possible implementation is: and the terminal equipment sends the acquired third indication information to the network equipment. Therefore, the network equipment can accurately determine the first resource and accurately receive the uplink information. Specifically, the terminal device may notify the network device of the acquired third indication information or the resource indicated by the third indication information.
Further, if the fourth resource is determined by the terminal device through the third resource and the preset rule instead of the fourth resource indicated to the terminal device by the network device through the fourth indication information, the network device does not know that the terminal device has sent the preprocessed uplink information corresponding to the third resource on the fourth resource, and the network device does not know that the information received on the fourth resource and the information received on the first resource should be demodulated and decoded together, which may cause the network device to fail to obtain the uplink information correctly. To avoid this, one possible implementation is: and the terminal equipment sends a fourth resource used for sending the preprocessed uplink information corresponding to the third resource to the network equipment, and/or the terminal equipment indicates the behavior of sending the preprocessed uplink information corresponding to the third resource in the fourth resource to the network equipment. So that the network device demodulates and decodes the information received on the fourth resource and the information received on the first resource together, thereby obtaining correct uplink information.
Specifically, before or after performing step 104, the terminal device may send a message to the network device for reporting one or a combination of the following information:
-third indication information acquired by the terminal device.
-the resource indicated by the third indication information determined by the terminal device;
-the terminal device is configured to send a fourth resource of the preprocessed uplink information corresponding to the third resource.
-the terminal device transmitting uplink information corresponding to the third resource on the fourth resource.
The terminal device can notify the network device that the terminal device does not send the preprocessed uplink information corresponding to the resource in the third resource through the information.
Accordingly, when the network device performs step 105, the network device may perform the inverse preprocessing process only on the information received on the first resource, without considering the information received on the third resource, so as to obtain the uplink information; or performing inverse preprocessing on the uplink information received on the first resource and the fourth resource jointly to obtain correct uplink information.
Still taking fig. 5 as an example, the information received by the network device in the first resource corresponds to z after the terminal device preprocesses0(0),z0(1),...z,0M(0-1)、z1(0),z1(1),...,z1(M1-1)、z2(0),z2(1),...,z2(M2-1)、z3(0),z3(1),...,z3(M3-1)、z4(0),z4(1),...,z4(11)、z4(24),z4(25),...,z4(M4-1)、z5(0),z5(1),...,z5(11)、z5(24),z5(25),...,z5(M5-1)、z6(0),z6(1),...,z6(M6-1)、z7(0),z7(1),...,z7(M7-1)、z8(0),z8(1),...,z8(M8-1)、z9(0),z9(1),...,z9(M9-1)、z10(0),z10(1),...,z10(M10-1)、z11(0),z11(1),...,z11(M11-1). The network equipment carries out inverse preprocessing such as inverse transformation precoding, digital demodulation, interference elimination, decoding and the like on the received information, and can obtain the uplink information sent by the terminal equipment.
Optionally, if the network device determines that the terminal device sends the preprocessed uplink information corresponding to the third resource on the fourth resource, the information received by the network device on the fourth resource corresponds to the preprocessed uplink information z of the terminal device4(12),z4(13),...,z4(23)、z5(12),z5(13),...,z5(23). Then, the terminal device performs inverse preprocessing on the information received in the first resource and the information received in the fourth resource together, so as to obtain the uplink information sent by the terminal device. Because the terminal device sends the preprocessed information corresponding to the third resource in the fourth resource, compared with the situation that the terminal device sends the preprocessed information corresponding to the first resource only in the first resource, the network device is connectedThe probability of correctly obtaining the original uplink information sent by the terminal equipment through the inverse preprocessing is improved.
In step 105, when the network device performs inverse preprocessing on the received uplink information, it is necessary to estimate the uplink channel based on the DMRS transmitted by the terminal device. Therefore, in order to ensure that the network device can perform inverse preprocessing on the uplink information transmitted by the terminal device according to the DMRS, the network device avoids as much as possible that the resource that the terminal device is instructed to avoid in the third indication information is the resource that the terminal device transmits the DMRS. Typically, a terminal device transmits a DMRS on a resource on the 4 th time domain symbol in one slot on a scheduling resource allocated to it by the network device.
In general, when a terminal device needs to transmit a DMRS on an mth time domain symbol in a scheduling resource, the terminal device may detect whether other terminal devices are performing uplink transmission on X time domain symbols before the mth time domain symbol, and resources for uplink transmission of the other terminal devices are overlapped with the scheduling resource in a frequency domain, that is, detect third indication information and determine whether resources indicated by the third indication information are overlapped with the scheduling resource. And if the terminal does not detect that other terminals are carrying out uplink transmission, the terminal equipment determines to send the DMRS on the mth time domain symbol in the scheduling resource. Otherwise, if the terminal detects that other terminals are performing uplink transmission, and the terminal may not send the DMRS for avoiding resources of other terminal devices performing uplink transmission, the network device receives the uplink information, but does not receive the DMRS, and cannot correctly decode the uplink information, so that the uplink transmission of the terminal device is invalid.
In order to avoid this situation, the resource allocated by the network device to the other terminal, that is, the resource indicated by the third indication information to be avoided by the terminal device, does not include the resource on the X time domain symbols before the time domain symbol where the terminal device transmits the DMRS.
The terminal equipment needs to detect whether other terminal equipment is performing uplink transmission on Y time domain symbols after the terminal equipment sends the DMRS, and because the terminal equipment needs time to switch from a sending state to a detection state after the terminal equipment sends the DMRS, if other terminal equipment performs uplink transmission at this time, the terminal equipment may not detect third indication information of the other terminal equipment performing uplink transmission, so that the terminal equipment continues to send data without avoiding resources of the other terminal equipment performing uplink transmission, and data collision is caused. Therefore, the resource allocated by the network device to the other terminal, that is, the resource indicated by the third indication information, does not include the resource on Y time domain symbols after the time domain symbol where the terminal device transmits the DMRS.
For example, when X and Y are both 1, as shown in fig. 15, the resource indicated by the third indication information does not include: in the scheduling resource of the terminal equipment, the terminal equipment transmits resources on 1 time domain symbol before and 1 time domain symbol after the resource where the DMRS is located. Of course, according to practical applications, X and Y may also take other values, or only the resource indicated by the third indication information may be limited not to include the resource on the time domain symbol where the terminal device transmits the DMRS and the X time domain symbols before the time domain symbol where the DMRS is located, or only the resource indicated by the third indication information may be limited not to include the resource on the time domain symbol where the terminal device transmits the DMRS and the Y time domain symbols after the time domain symbol where the DMRS is located.
In a possible implementation manner, the third indication information is used to indicate resources other than the first time domain symbol set, where the first time domain symbol set includes a time domain symbol used by the terminal device to transmit the DMRS, and X time domain symbols before the time domain symbol where the DMRS is located and/or Y time domain symbols after the time domain symbol where the DMRS is located. Specifically, the third indication information sent by the network device may represent the resource indicated by the third indication information in the form of a bitmap. Because the resource indicated by the third indication information does not include the resource of the first time domain symbol set, the third indication information is limited to only indicate the resource except the first time domain symbol set, so that the load of the third indication information can be reduced, the transmission resource can be saved, and the transmission efficiency can be improved.
For example, as shown in fig. 8, the terminal device transmits the DMRS on the time domain symbol 3 and the time domain symbol 10, and the scheduling resources on the previous time domain symbol (time domain symbol 2, time domain symbol 9) and the subsequent time domain symbol (time domain symbol 4, time domain symbol 11) cannot be the resources indicated by the third indication information. After the resources are excluded, the third indication information may indicate, by using information including 8 bits, the resource that the terminal device needs to avoid, where the 8 bits respectively correspond to a time domain symbol 0, a time domain symbol 1, a time domain symbol 5, a time domain symbol 6, a time domain symbol 7, a time domain symbol 8, a time domain symbol 12, and a time domain symbol 13 in the scheduling resource, and each bit is used to indicate whether the resource on the time domain symbol corresponding to the bit needs to avoid. For example, if the value on one bit is 0, it indicates that the resource on the time domain symbol corresponding to the bit is not allocated to other terminal devices, and the terminal device may use the resource for uplink transmission without back-off; if the value is 1, it indicates that the resource on the time domain symbol corresponding to the special service is allocated to other terminal equipment, and the terminal equipment cannot use the resource for uplink transmission. However, if the third indication information is not limited to indicate resources other than the first time domain symbol set, the third indication information needs 14 bits of information to indicate resources on each time domain symbol, also in the form of a bitmap.
