Description

Technical field

The present application relates to the field of wireless communications technologies, and in particular, to an uplink transmission method and apparatus.

Background technique

In order to further improve the network transmission speed, improve the user experience, and apply wireless communication services for large-scale Internet of Things, research on the fifth generation mobile communication technology (5G) is being widely carried out.

Future 5G applications will cover three types of scenarios: Enhanced Mobile Broad Band (eMBB), Ultra Reliable Low Latency Communication (URLLC), and Massive Machine Type Communication (Massive Machine Type Communication). mMTC). The eMBB scenario refers to the performance improvement of the user experience and the like on the basis of the existing mobile broadband service scenario. For example, eMBB can be applied to high-traffic mobile broadband services such as 3D or ultra-high-definition video; mMTC can be applied to large-scale Internet of Things services; URLLC can be applied to unmanned, industrial automation and other applications requiring low latency and high reliability. business.

There are two basic requirements for the URLLC service: one is the higher latency requirement brought by the service emergency. For example, the current uplink and downlink user plane delay cannot exceed 0.5 ms; the second is the higher reliability requirement, for example. The error rate within 1ms cannot exceed 0.001%. If the resources of the eMBB service and the URLLC service are time-division multiplexed, the delay of the URLLC service is long. If the resources of the eMBB service and the URLLC service are frequency-division multiplexed, the URLLC service is allocated when there is no URLLC service. The frequency band used cannot be used for data transmission of eMBB services, resulting in low resource utilization efficiency.

Therefore, a technical solution is needed to avoid resource conflicts while ensuring resource utilization efficiency.

Therefore, error correction and error detection techniques are usually applied to digital signals, that is, error correction and error detection coding techniques to enhance signals in the channel. Improve the reliability of the system by resisting various interferences during transmission. Specifically, the transmitting end may add redundant data to the original data that needs to be sent, and the redundant information is related to the original data; the receiving end may detect and correct the received data according to the correlation between the redundant data and the original data. For example, the terminal device may perform channel coding on the uplink information by using a Low Density Parity Check Code (LDPC) or a Polar Code. For example, if the uplink information includes the uplink service information, the terminal device uses the LDPC code to perform channel coding on the uplink information. If the uplink information includes only the uplink control information and does not include the uplink service information, the terminal device uses the Polar code to perform channel coding on the uplink information. . For example, the information generated by the terminal device after channel coding the uplink information is b(0), . . . , b(M _bit -1), where M _bit is 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 perform other pre-processing procedures on the channel-encoded uplink information. Taking the uplink waveform sent by the terminal device as a single-carrier frequency-division multiple access (SC-FDMA) signal as an example, other pre-processing procedures performed by the terminal device on the channel-encoded uplink information may be as shown in the figure. 2 is shown.

Scrambling: In uplink transmission, each terminal device uses its dedicated scrambling code sequence to scramble the channel-encoded uplink information. For example, the information scrambled by the information b(0), ..., b(M _bit -1) generated by channel coding the uplink information is

Modulation: the above-mentioned scrambled uplink information

Digital modulation, such as QPSK modulation, 16QAM modulation, etc., is performed to obtain complex symbols d(0), ..., d(M _symb -1), where M _symb represents the number of bits modulated by the uplink information.

Transform Precoder: Dynamically determines the precoding type (Discrete Fourier Transform DFT type and length) based on different input lengths.

The digitally modulated M _symb symbols are divided into P groups, and the digitally modulated symbols in each group correspond to one SC-FDMA symbol in the scheduling resource, and DFT transform processing is performed on each group of digitally modulated symbols. . After the conversion precoding process, the corresponding pre-coded information z _u (0), ..., z _u (M _u -1) is output corresponding to the SC-FDMA symbol u. The uplink information after the DFT transform included on the symbol u is M _u symbols.

Resource Element Mapper: maps the information of the transform precoding process in each group to each SC-FDMA symbol of the scheduling resource, and the frequency domain is followed by the time domain. After the physical resource mapping, the terminal device determines the correspondence between the data block of the SC-FDMA signal and all or part of the scheduling resources, that is, determines the data block to be sent on each resource block. Specifically, the modulated complex symbols are respectively corresponding to resources other than the resources of the scheduling resource except the terminal device that transmits a Demodulation Reference Signal (DMRS), and each resource unit corresponds to a modulated complex number. symbol. For example, FIG. 3 is a correspondence relationship between scheduling resources and pre-processed uplink information. The uplink information and the uplink resource after the pre-processing process satisfy the preset correspondence. For example, the uplink information z ₀ (0) of the terminal device after the conversion precoding process corresponds to the resource with the lowest frequency on the symbol 0 in the scheduling resource. The uplink information z ₀ (1) of the terminal device after the conversion precoding process is corresponding to the resource with the second lowest frequency on the symbol 0 in the scheduling resource.

SC-FDMA signal gen.: On each SC-FDMA symbol, the terminal device converts the information of the conversion precoding process mapped on each SC-FDMA symbol into an SC-FDMA signal generation manner to SC-FDMA signal.

It should be noted that the pre-processing process shown in FIG. 2 is only one embodiment of the present application, and the pre-processing process may include only a part of the process shown in FIG. 2, and may also include a process not shown in FIG. This is not a limitation.

Step 104: The terminal device sends the first information on the first resource. The first information is all or part of the pre-processed uplink information, and the first resource is a resource other than the second resource and/or the third resource in the scheduling resource.

The second resource includes an intersection of the scheduling resource and the resource indicated by the second indication information, that is, the first overlapping resource, and the second indication information is indication information used by the terminal device to indicate the resource before the uplink information is pre-processed. Optionally, the second information may be information received by the terminal device through the high layer signaling, for example, Radio Resource Control (RRC) information or information in a Medium Access Control (MAC).

The third resource includes an intersection of the scheduling resource and the resource indicated by the third indication information, that is, the second overlapping resource. The third indication information is used by the terminal device to perform the pre-processing of the uplink information or the pre-processing period for indicating the resource. Instructions. Optionally, the third indication information is information that is received by the terminal device through the physical downlink control channel or that is obtained by the terminal device by detecting signals sent by other terminal devices.

When the terminal device performs the foregoing step 104, if the first resource is a resource other than the second resource in the scheduling resource, the first information is all pre-processed uplink information; if the first resource is other than the third resource in the scheduling The first information is the pre-processed uplink information except the information corresponding to the third resource in the pre-processed uplink information; if the first resource is a resource other than the second resource and the third resource in the scheduling The first information is the pre-processed uplink information in the pre-processed uplink information except the information corresponding to the third resource.

Optionally, the foregoing first information is information that is determined according to a preset rule and that is corresponding to the first resource; when the first resource is a resource other than the second resource in the scheduling resource, or when the first When the resource is the resource other than the second resource and the third resource in the scheduling resource, the preset rule is a correspondence between the pre-processed uplink information and the resource other than the second resource in the scheduling resource. When the first resource is a resource other than the third resource in the scheduling resource, the preset rule is a correspondence between the pre-processed uplink information and the scheduling resource.

Optionally, if the terminal device generates an SC-FDMA signal in the pre-processing, the terminal device sends the first information, that is, the first information, on the first resource by using the SC-FDMA signal when performing the foregoing step 104. The SC-FDMA signal corresponding to the first resource after being mapped with the resource. Of course, the terminal device can also generate signals of other waveforms and send them to the network device, which is not limited in this embodiment of the present invention.

Step 105: The network device receives the uplink information preprocessed by the terminal device on the first resource, and performs inverse preprocessing.

The network device receives the uplink information preprocessed by the terminal device on the first resource, and after the inverse pre-processing, the process of the inverse pre-processing and the process of the terminal pre-processing the uplink information respectively correspond. The network device obtains the uplink information sent by the terminal device accordingly.

In some embodiments, the terminal device may further receive the second indication information sent by the network device before performing the pre-processing of the uplink information in the step 103, where the second indication information is used to indicate that the terminal device evades the second indication information. The indicated resource, that is, the uplink transmission is not performed on the resource indicated by the second indication information. For example, the network device may reserve a part of the resources for the data transmission of the URLLC service. Therefore, the network device may notify the terminal device that performs other service transmission by using the second indication information to perform uplink transmission on the reserved resource.

The terminal device may determine, according to the resource indicated by the second indication information and the scheduling resource, the second resource, where the resource indicated by the second indication information and the scheduling resource indicated by the first indication information are intersected, that is, the first overlapping resource ,As shown in Figure 4. At this time, the terminal device may not consider the second resource when performing pre-processing. For example, when the terminal device performs channel coding on the uplink information, the code rate that can be channel coded corresponds to the number of uplink information and resources other than the second resource in the scheduling resource. When the terminal device maps the uplink information after the pre-processing to the uplink resource, the uplink information after the pre-processing on the second resource is not considered.

Specifically, the terminal device obtains an indication that the second resource cannot be used to transmit the uplink information before the uplink information is pre-processed, that is, the first resource does not include the second resource in the scheduling resource. 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 is required to determine the coding rate of the channel coding, and the coding rate is a ratio of the data amount of the uplink information to be transmitted and the data amount of the channel information after the channel coding. The amount of data of the uplink information after channel coding is limited by the size of resources that can be used when the terminal device performs uplink transmission. Therefore, when the terminal device determines the second resource according to the second indication information sent by the network device before the channel coding, the terminal device needs to transmit the second resource from the uplink device that can be used by the terminal device when determining the code rate of the channel coding. The resource is excluded, that is, the code rate of the channel coding corresponds to the number of uplink information and the resources of the scheduling resource other than the second resource. Thus, the information corresponding to the second resource does not exist in the pre-processed uplink information.

In other embodiments, the terminal device may receive the third indication information sent by the network device or other terminal device after the pre-processing of the uplink information or the pre-processing of the uplink information by the terminal device, the third indication. The information is also used to instruct the terminal device to avoid the resource indicated by the third indication information, and does not perform uplink transmission on the resource indicated by the third indication information, that is, the first resource does not include the third resource. For example, the terminal device A performs the uplink transmission of the eMBB service on the resources scheduled by the network device. At this time, the terminal device B needs to perform the uplink transmission of the URLLC service, and the network device allocates the scheduling resource to the terminal device B, and is the terminal. The scheduling resource allocated by the device B overlaps with the scheduling resource for the terminal device A. In order to ensure the data transmission requirement of the URLLC service, the terminal device A needs to avoid, and does not perform uplink transmission on the overlapping part of the resources to avoid collision, resulting in the terminal. Data transmissions of both device A and terminal device B are affected.

The terminal device may determine, according to the resource indicated by the third indication information and the scheduling resource, the third resource, where the third resource includes an intersection of the resource indicated by the third indication information and the scheduling resource indicated by the first indication information, that is, the second overlapping resource ,As shown in Figure 4.

The third indication information is the indication information received by the terminal device after the pre-processing or during the processing to indicate that the terminal device evades 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 is used to send the pre-processed uplink information when the channel is encoded. In this way, the pre-processed uplink information has information corresponding to the preset resource and the third resource.

In some embodiments, the terminal device receives the second indication information sent by the network device before performing the pre-processing in step 103; meanwhile, the terminal device receives the network device or other terminal after performing the pre-processing or during the pre-processing. The third indication information sent by the device, that is, the first resource is a resource other than the second resource and the third resource in the scheduling resource.

For example, before the terminal device performs pre-processing on the uplink information, the second resource determined according to the second indication information is the last symbol in the scheduling resource and the 12 resource units having the lowest frequency position on the second-to-last symbol, as shown in the figure. As shown in FIG. 5, the terminal device does not consider the second resource when determining the coding rate of the channel coding in the pre-processing. Correspondingly, in processing the physical resource mapping process, the terminal device maps the information of the precoding process on the last symbol and the penultimate symbol, starting from the thirteenth resource unit on the symbol, as shown in FIG. 5 Show. The terminal device receives the third indication information after pre-processing the uplink information or during the pre-processing, and the third resource determined according to the third indication information is the symbol 5 in the scheduling resource and the frequency position 13-24 in the symbol 6 12 resource units, and the pre-processed uplink information already includes information corresponding to the third resource, such as z ₄ (12), z ₄ (13), ..., z ₄ (23) ) and z ₅ (12), z ₅ (13), ..., z ₅ (23).

In the embodiment shown in FIG. 5, if the first resource is a resource other than the third 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 terminal In order to avoid collision with information sent by other terminal devices, the device does not send uplink information on the third resource when transmitting the uplink information, which may result in single carrier characteristics of uplink information sent by other resources on the symbol where the third resource is located. destroyed.

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 of information corresponding to the scheduling resources on the Yth symbol in the preprocessed uplink information ( The Cubic Metric, CM) value is 1.26. If the third resource includes one of the scheduling resources on the Yth symbol, according to the foregoing embodiment, the information corresponding to the third resource exists in the pre-processed uplink information, and the terminal device does not send the third resource corresponding to the third resource. After the pre-processed uplink information, but only the pre-processed information corresponding to other RBs on the symbol is transmitted, the CM value of the information transmitted on the symbol is increased (about 1.5), and the transmission efficiency is lowered. If the terminal device transmits only the pre-processed uplink information corresponding to fewer RBs, the CM value of the transmitted signal continues to increase, and the transmission efficiency continues to decrease; if the terminal device transmits only on one RB Corresponding pre-processed uplink information, then the CM value of the transmitted signal is as high as 3.7, and the transmission efficiency is very low.

Still taking FIG. 5 as an example, the pre-processed uplink information satisfies the single carrier characteristic on each symbol. However, after the terminal device determines the third resource, if the terminal device does not send the third resource in symbol 5 and symbol 6. Corresponding uplink information will result in z ₄ (0), z ₄ (1), ..., z ₄ (11) and z ₄ (24), z ₄ (25), ... transmitted on symbol 5. , z ₄ (M ₄ -1), and z ₅ (0), z ₅ (1), ..., z ₅ (11) and z ₅ (24), z ₅ (25) transmitted on symbol 6. , ..., z ₅ (M ₅ -1) does not satisfy the single carrier characteristic, which in turn causes the transmission efficiency of the terminal device on symbol 5 and symbol 6 to decrease.

In order to avoid the above problem, in a possible implementation manner of the embodiment of the present invention, the third resource that is determined by the terminal device may include: the second overlapping resource is located on the same time domain symbol as the second overlapping resource. The intersection of resources and scheduling resources, except for the second overlapping resources. That is, the third resource includes all resources in the scheduling 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 of the resources on the same time domain symbol as the second overlapping resource. The terminal device does not send the pre-processed uplink information corresponding to the third resource on the first resource.

In order to avoid the above problem, another possible implementation in the embodiment of the present invention is as follows. According to the foregoing embodiment, the pre-processed uplink information has information corresponding to the third resource. The terminal device does not transmit the pre-processed uplink information corresponding to the third resource but only transmits other pre-processed information on the symbol, and the information does not satisfy the single carrier characteristic. In order to avoid the secondary affecting terminal device, the uplink information before the DFT transform on the symbol can be truncated, and the DFT transform is performed again on the truncated uplink information. Thus, the single carrier characteristics of the information transmitted by other resources on the symbol after pre-processing can be guaranteed.

Still taking FIG. 5 as an example, if z ₄ (0), z ₄ (1), ..., z ₄ (11) z ₄ (24), z ₄ (25), ... are directly transmitted on symbol 5. , z ₄ (M ₄ -1), since these signals do not satisfy the single carrier characteristic, the transmission efficiency of the terminal device on symbol 5 and symbol 6 is lowered. To solve this problem, the terminal device can send z ₄ (0), z ₄ (1), ..., z ₄ (11) and z ₄ (24), z ₄ (25), .. on the symbol 5. The information before the DFT conversion corresponding to a part of the information in z ₄ (M ₄ -1) is re-executed by the DFT transform. Since the uplink information after the DFT conversion is re-executed, the single carrier characteristic can be satisfied. In this way, the terminal device does not send the pre-processed uplink information corresponding to the third resource on the first resource, but sends the uplink information after the DFT transform is performed on the symbol where the third resource is located, and the information satisfies the single carrier characteristic. The problem that the transmission efficiency of the terminal device on the symbol 5 is reduced can be solved. For example, the DFT-transformed uplink information z ₄ (0), z ₄ (1), ..., z ₄ (M ₄ -1) corresponding to the resource on symbol 5 is d ₄ (0) before the DFT transform. , d ₄ (1), ..., d ₄ (M ₄ -1); the terminal device may d ₄ (0), d ₄ according to the size of the resources other than the third resource usable on the symbol 5 The partial information in 1), ..., d ₄ (M ₄ -1) re-executes the DFT transform, and the terminal device transmits the uplink information after the DFT transform is re-executed on the symbol 5, so that the terminal device is on the symbol 5 The transmitted uplink information satisfies the single carrier characteristic.

However, considering the cost of the terminal device, the terminal device usually does not support the discrete Fourier transform of all points. The scheduling resource 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 supported by the terminal device. For example, if the scheduling resource is 15 RBs, and the third resource includes the width of each of the 2 RBs on the sixth and seventh symbols, then the remaining resources except the third resource are on the sixth and seventh symbols. It is the width of 13 RBs. According to the foregoing embodiment, the terminal device needs to perform the DFT transformation on the pre-processed uplink information corresponding to the resources other than the third resource in the scheduling resource, that is, the uplink information corresponding to the 13 RBs. However, the terminal device can perform DFT change on the uplink information corresponding to the Q RBs, where

α ₂ , α ₃ and α ₅ are all non-negative integers, however 13 obviously does not belong to the range of Q, that is, beyond the capabilities of this terminal device. Therefore, a possible implementation method is that the third resource includes one RB in addition to the second overlapping resource, so that the number of remaining resources in the scheduling resource except the third resource can be satisfied on the symbol where the third resource is located. The value range of Q matches the number of points supported by the DFT transform of the terminal device.

Therefore, the third resource that is determined by the terminal device may include, in addition to the second overlapping resource, N (j) resources adjacent to the second overlapping resource on the jth time domain symbol in the second overlapping resource. Element (Resource Element, RE) (or RB), where j ∈ [1, J], J represents the number of time domain symbols included in the second overlapping resource, and N(j) satisfies N(j)=K ( j) the minimum value of -L(j)-Q, where Q is a value satisfying the number of points of the terminal device for DFT, and K(j) represents the number of REs (or RBs) included in the jth time domain symbol of the scheduling resource L(j) represents the number of REs (or RBs) that the second overlapping resource contains on the jth time domain symbol. In addition, since N(i) satisfies the minimum value of N(i)=K(i)-L(i)-Q, the first resource reserved for the terminal device is more, and the resource utilization efficiency can be more assured. However, in practical applications, the value of N(i) can also be adjusted according to different scenario requirements, for example, N(i) is satisfied to satisfy N(i)=K(i)-L(i)-Q. The maximum or other. If the number of REs (or RBs) included in each time domain symbol is equal, the resulting value of each N(j) is the same; however, in some embodiments, the second overlapping resource is in each time domain symbol The number of REs (or RBs) included is not equal, and the value of each N(j) obtained may also 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 pre-processed uplink There is no information corresponding to the second resource in the information. The terminal device performs a conversion precoding process on the information corresponding to other resources on the symbol where the second resource is located. Taking the conversion precoding process as the DFT as an example, considering the cost problem of the terminal device, the terminal device usually does not support the DFT of all points; and on the symbol where the second resource is located, the remaining resources of the scheduling resource except the second resource The number may not match the number of points of the DFT transform supported by the terminal device.

For example, if the scheduling resource is 8 RBs and the second resource includes 1 RB on each of the

symbols

4 and 5, the remaining resources are 7 RBs except for the second resource on the

symbols

4 and 5. According to the foregoing embodiment, the information corresponding to the second resource does not exist in the uplink information that is pre-processed by the terminal device. The terminal device needs to perform DFT conversion on the pre-processed uplink information corresponding to the resources other than the second resource in the scheduling resource on the symbol, that is, the terminal device may not support the number of points. The DFT of the number of subcarriers included in 7 RBs. Therefore, a possible implementation manner is that the second resource includes one RB in addition to the first overlapping resource, so that the scheduling resource on the symbol where the second resource is located, except for the resource of the second resource on the symbol, remains. The number of resources matches the number of points supported by the terminal device for DFT transformation. That is, the second resource further includes N(i) REs adjacent to the first overlapping resource on the i-th time domain symbol of the first overlapping resource, or N(i) RBs adjacent to the first overlapping resource. Where i ∈ [1, I], I represents the number of time domain symbols included in the first overlapping resource, and N(i) is a condition that satisfies N(i)=K(i)-L(i)-Q a minimum value, Q is a value that satisfies the number of points of the terminal device for the discrete Fourier transform DFT, and K(i) represents the number of REs (or RBs) included in the i-th time-domain symbol of the scheduling resource. L(i) represents the number of REs (or RBs) included in the i-th time domain symbol of the first overlapping resource. Usually, Q is satisfied

The values of α ₂ , α ₃ and α ₅ are all non-negative integers. As shown in FIG. 8, on the first time domain symbol (the immediate 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 is The time domain symbol includes L(i)=5 REs, and at this time, the remaining 7 REs on the

time domain symbol

5, 7 cannot satisfy

Therefore, N cannot take 0; when N is 1, Q=6, 6 can satisfy

That is, α ₂ =1, α ₃ =1, and α ₅ =0, so N=1 is the minimum value that satisfies the condition. In the case shown in FIG. 8, the first overlapping resource has the same L(i) value on the first time domain symbol and on the second time domain symbol, so the obtained N values are the same; however, in some In an embodiment, the L(i) values of the first overlapping resources on different time domain symbols may also be unequal, so the obtained N values may also be different.

In addition, since N(i) satisfies the minimum value of N(i)=K(i)-L(i)-Q, the first resource reserved for the terminal device is more, and the resource utilization efficiency can be ensured. However, in practical applications, the value of N(i) can also be adjusted according to different scenario requirements, for example, N(i) is satisfied to satisfy N(i)=K(i)-L(i)-Q. The maximum or other.

In another possible implementation manner, in order to avoid the scheduling resource on the symbol where the second resource is located, except for the resource of the second resource on the symbol, the number of remaining resources may be the number of points of the DFT transformation supported by the terminal device. The second resource that is determined by the terminal device may include, in addition to the first overlapping resource, an intersection of the resource and the scheduling resource that are located on the same time domain symbol as the first overlapping resource, except for the first overlapping resource. The other resources, that is, the second resource, are all resources in the scheduling resource that are 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 determining method: including only overlapping resources, or all resources on the time domain symbol corresponding to overlapping resources in the scheduling resource, or including overlapping resources and scheduling N REs or RBs in the resource that are adjacent to the overlapping resources in the frequency domain. In a specific implementation, when determining the second resource, any one of the foregoing methods may be used; when determining the third resource, any one of the foregoing methods may also be used, which is not limited by the embodiment of the present invention. For ease of understanding, the following is described in terms of several specific embodiments.

Example 1

As shown in FIG. 10, the terminal device determines, according to the first indication information, the second indication information, and the third indication information, the scheduling resource, the first overlapping resource, and the second overlapping resource of the terminal device. As shown in the figure, the second resource determined by the terminal device includes only the first overlapping resource, and the determined third resource includes all resources on the time domain symbol corresponding to the second overlapping resource in the scheduling resource.

Example 2

As shown in FIG. 11, the terminal device determines, according to the first indication information, the second indication information, and the third indication information, a scheduling resource, a first overlapping resource, and a second overlapping resource of the terminal device. As shown in the figure, the second resource determined by the terminal device includes a first overlapping resource, and N(i) REs adjacent to the first overlapping resource on the i-th time domain symbol of the first overlapping resource, N(i To satisfy the minimum value of N(i)=K(i)-L(i)-Q. The third resource determined by the terminal device includes all resources on the time domain symbol corresponding to the second overlapping resource in the scheduling resource.

Example 3

As shown in FIG. 12, the terminal device determines, according to the first indication information, the second indication information, and the third indication information, the scheduling resource, the first overlapping resource, and the second overlapping resource of the terminal device. As shown in the figure, the second resource determined by the terminal device includes all resources on the time domain symbol corresponding to the first overlapping resource in the scheduling resource. The third resource determined by the terminal device includes a second overlapping resource, and N(j) REs adjacent to the first overlapping resource on the jth time domain symbol of the second overlapping resource, where N(j) is satisfied with N ( j) = K(j) - L(j) - The minimum value of Q.

Example 4

As shown in FIG. 13, the terminal device determines, according to the first indication information, the second indication information, and the third indication information, the scheduling resource, the first overlapping resource, and the second overlapping resource of the terminal device. As shown in the figure, the second resource determined by the terminal device includes all resources on the time domain symbol corresponding to the first overlapping resource in the scheduling resource. The third resource determined by the terminal device includes all resources on the time domain symbol corresponding to the second overlapping resource.

Example 5

As shown in FIG. 14, the terminal device determines, according to the first indication information, the second indication information, and the third indication information, a scheduling resource, a first overlapping resource, and a second overlapping resource of the terminal device. As shown in the figure, the second resource determined by the terminal device includes a first overlapping resource, and N(i) REs adjacent to the first overlapping resource on the i-th time domain symbol of the first overlapping resource, N(i To satisfy the minimum value of N(i)=K(i)-L(i)-Q. The third resource determined by the terminal device includes a second overlapping resource, and N(j) REs adjacent to the first overlapping resource on the jth time domain symbol of the second overlapping resource, where N(j) satisfies N ( j) = K(j) - L(j) - The minimum value of Q.

Of course, in addition to the foregoing embodiment, the method for determining the second resource and the third resource provided by the embodiment of the present invention may further obtain other combinations, which are not exemplified herein.

In the above step 104, if the first resource determined by the terminal device is the third resource in the scheduling resource, or the second resource and the third resource in the scheduling resource, a possible implementation manner is that the terminal device is not in the first The uplink information corresponding to the third resource is transmitted on the three resources to avoid conflict with information sent by other terminal device devices.

The uplink information of the channel coding has redundant information, so that the network device checks and corrects the received uplink information. Therefore, in some cases, the network device can decode the correct uplink information even if the terminal device does not send the uplink information corresponding to the third resource. However, in some cases, for example, the third resource has a large amount of information, and the network device does not receive a large amount of pre-processed uplink information, and cannot be correctly decoded. At this time, the terminal device may send the fourth resource. The pre-processed uplink information corresponding to the third resource. The fourth resource may be a resource that the network device indicates to the terminal device by using the fourth indication information, or may be a resource that corresponds to the third resource by using the preset rule. For example, the preset rule may use the resources after the M time domain symbols after the scheduling resource, or after the M subframes, or after the M time slots as the fourth resource. In the embodiment shown in FIG. 5, the terminal device is not transmitting z ₄ (12), z ₄ (13), ..., z ₄ (23) and z ₅ (12), z ₅ (13). ),...,z ₅ (23), however, the terminal device can transmit z ₄ (12), z ₄ (13), ..., z ₄ (23) and z ₅ (12) in the fourth resource, z ₅ (13),...,z ₅ (23).

Optionally, if the third indication information is not sent by the network device to the terminal device, but the terminal device is obtained by detecting information sent by the other terminal device, the network device does not know that the terminal does not include the uplink information. The third resource, which incorrectly demodulates and decodes the information received on the third resource together with the resources received on other resources, may cause the network device to fail to obtain the uplink information correctly. In order to avoid the occurrence of the situation, a possible implementation manner is: the terminal device sends the obtained third indication information to the network device. In this way, the network device 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 not indicated by the network device to the terminal device by using the fourth indication information, but the terminal device is determined by using the third resource and the preset rule, the network device does not know that the terminal device is in the fourth resource. The pre-processed uplink information corresponding to the third resource is sent, 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. Get the right information correctly. In order to avoid the occurrence of the situation, a possible implementation manner is: the terminal device sends a fourth resource for sending the pre-processed uplink information corresponding to the third resource to the network device, and/or the terminal. The device indicates, by the fourth resource, the behavior of the pre-processed uplink information corresponding to the third resource to the network device. So that the network device demodulates and decodes the information received on the fourth resource together with the information received on the first resource, 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 obtained by the terminal device.

a resource indicated by the third indication information determined by the terminal device;

The fourth resource used by the terminal device to transmit the pre-processed uplink information corresponding to the third resource.

The terminal device transmits uplink information corresponding to the third resource in the fourth resource.

The terminal device can notify the network device that the terminal device does not send the pre-processed uplink information corresponding to the resource in the third resource by using the foregoing information.

Correspondingly, when the network device performs the foregoing step 105, the network device may perform an inverse pre-processing process only on the information received on the first resource, without considering the information received on the third resource, thereby acquiring the uplink information; The uplink information received on the first resource and the fourth resource is jointly subjected to inverse pre-processing to obtain correct uplink information.

Still taking FIG. 5 as an example, the information received by the network device at the first resource corresponds to z ₀ (0), z ₀ (1), . . . , z ₀ (M ₀ -1) after the terminal device is preprocessed. z ₁ (0), z ₁ (1), ..., z ₁ (M ₁ -1), z ₂ (0), z ₂ (1), ..., z ₂ (M ₂ -1), z ₃ (0), z ₃ (1),...,z ₃ (M ₃ -1), z ₄ (0), z ₄ (1),...,z ₄ (11), z ₄ ( 24), z ₄ (25),...,z ₄ (M ₄ -1), z ₅ (0), z ₅ (1),...,z ₅ (11), z ₅ (24), z ₅ (25),...,z ₅ (M ₅ -1), z ₆ (0), z ₆ (1),...,z ₆ (M ₆ -1), z ₇ (0), z ₇ (1),...,z ₇ (M ₇ -1), z ₈ (0),z ₈ (1),...,z ₈ (M ₈ -1), z ₉ (0), z ₉ (1),...,z ₉ (M ₉ -1), z ₁₀ (0), z ₁₀ (1),...,z ₁₀ (M ₁₀ -1), z ₁₁ (0), z ₁₁ (1),...,z ₁₁ (M ₁₁ -1). The network device performs inverse pre-processing such as inverse conversion precoding, digital demodulation, descrambling, decoding, etc. on the received information, and obtains uplink information sent by the terminal device.

Optionally, if the network device determines that the terminal device sends the pre-processed uplink information corresponding to the third resource on the fourth resource, the information received by the network device in the fourth resource corresponds to the pre-processed z of the terminal device. ₄ (12), z ₄ (13),...,z ₄ (23), z ₅ (12), z ₅ (13),...,z ₅ (23). Then, the terminal device performs inverse pre-processing together with the information received by the first resource and the information received by the fourth resource, and obtains uplink information sent by the terminal device. Since the terminal device re-processes the pre-processed information corresponding to the third resource in the fourth resource, the network device passes the inverse pre-processing only after the first device sends the pre-processed information corresponding to the first resource. The probability of correctly obtaining the original uplink information sent by the terminal device is improved.

In addition, in the foregoing step 105, when the network device performs inverse pre-processing on the received uplink information, it is required to estimate the uplink channel according to the DMRS sent by the terminal device. Therefore, in order to ensure that the network device can perform inverse pre-processing on the uplink information sent by the terminal device according to the DMRS, the network device tries to avoid the resource indicated by the terminal device in the third indication information to send the DMRS resource to the terminal device. Typically, the terminal device transmits the DMRS to the resource on the fourth time domain symbol in one of the time slots on the scheduling resource allocated by the network device.

Generally, when the terminal device needs to send the DMRS on the mth time domain symbol in the scheduling resource, the terminal device detects, on the X time domain symbols before the mth time domain symbol, whether another terminal device is performing uplink transmission. And the resources for the uplink transmission by the other terminal devices overlap with the scheduling resource storage in the frequency domain, that is, detecting the third indication information and determining whether the resources indicated by the third indication information and the scheduling resources overlap. If the terminal does not detect that the other terminal is performing uplink transmission, the terminal device determines to send the DMRS on the mth time domain symbol in the scheduling resource. Otherwise, if the terminal detects that the other terminal is performing uplink transmission, the terminal may not be able to send the DMRS for the resources that the other terminal device performs the uplink transmission, the network device receives the uplink information, but does not receive the DMRS, and cannot correctly decode the uplink information. The uplink transmission of the terminal device is invalid.

In order to avoid this, the resources allocated by the network device to other terminals, that is, the resources indicated by the terminal device in the third indication information, do not include the X time domain symbols before the time domain symbol in which the terminal device sends the DMRS. Resources.

The terminal device needs to detect whether other terminal devices are in the uplink transmission on the Y time domain symbols after the DMRS is sent. Since the terminal device needs to transit from the sending state to the detecting state after transmitting the DMRS, if there is another time The terminal device performs uplink transmission, which may cause the terminal device to detect the third indication information that the other terminal device performs uplink transmission, so that the terminal device continues to send data without omitting resources of other terminal devices for uplink transmission, thereby causing data collision. . Therefore, the resources allocated by the network device to other terminals, that is, the resources indicated by the third indication information, do not include resources on the Y time domain symbols after the terminal device sends the time domain symbol in which the DMRS is located.

For example, when the foregoing X and Y are both 1, as shown in FIG. 15, the resource indicated by the third indication information does not include: one time domain before the terminal device sends the resource where the DMRS is located in the scheduling resource of the terminal device. The symbol and the resources on the next time domain symbol. Of course, according to the actual application, X and Y may take other values, or may only limit the resources indicated by the third indication information to include the time zone symbol of the DMRS and the time zone symbol of the DMRS. The resource on the domain symbol, or the resource indicated by the third indication information may not include the resource on the Y time domain symbol after the time domain symbol in which the terminal device sends the DMRS and the time domain symbol in the DMRS.

In a possible implementation, 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 send the DMRS, and where the DMRS is located. The X time domain symbols preceding the time domain symbol and/or the Y time domain symbols following the time domain symbol in which 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 a form of a bit bitmap. The resource indicated by the third indication information does not include the resource of the first time domain symbol set. Therefore, limiting the third indication information to only indicating resources other than the first time domain symbol set may reduce the load of the third indication information. , saving transmission resources and improving transmission efficiency.

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, in its previous time domain symbol (time domain symbol 2, time domain symbol 9) and the latter time domain symbol (time) The scheduling resource on the domain symbol 4 time domain symbol 11) cannot be the resource indicated by the third indication information. After excluding the foregoing resources, the third indication information may indicate, by using information including 8 bits, the resources that the terminal device needs to avoid, and the 8 bits respectively correspond to the time domain symbol 0, the time domain symbol 1, and the time domain symbol 5 in the scheduling resource. The time domain symbol 6, the time domain symbol 7, the time domain symbol 8, the time domain symbol 12, and the time domain symbol 13, each bit is used to indicate whether the resource on the time domain symbol corresponding to the bit needs to be avoided. For example, if the value of a 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 can use the resource for uplink transmission without evading; if the value is 1, Then, the resource on the time domain symbol corresponding to the spy is allocated to other terminal devices, and the terminal device cannot use the resource for uplink transmission. However, if the third indication information is not restricted for indicating resources other than the first time domain symbol set, and is also a bit bitmap manner, the third indication information requires 14 bits of information to indicate resources on the respective time domain symbols.
