Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a data transmission processing method and apparatus. Background Technology

[0002] With the development and evolution of mobile communications, 6G networks have become a new research direction in wireless communication. The increase in the number of connected devices is one of the important driving forces. To avoid initial access and data transmission from a massive number of terminals, and given the limitations of network coordination signaling and data transmission resources, non-coordinated non-orthogonal multiple access (NOAMI) technology has been proposed. In NOAMI, a massive number of terminals need to share resources; therefore, the transmitted signals between terminals need to be separated as much as possible so that the base station can detect the data from each terminal individually.

[0003] However, existing data transmission methods require 2 bits when the data contains P bits. P Given Q distinct ZC sequences, assuming these sequences have Q roots and CS cyclic shifts, does Relation 2 hold? P If the value is approximately Q*CS, then the base station typically needs to perform Q correlation operations. This results in high processing complexity for the transmission of massive amounts of data and also reduces the detection performance of ZC sequences. Summary of the Invention

[0107] In this embodiment of the invention, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0108] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0109] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0110] This invention provides a data transmission processing method and apparatus. The method and apparatus are based on the same concept, and since the principles by which they solve the problem are similar, their implementations can be referred to interchangeably; repeated details will not be repeated.

[0111] like Figure 1 As shown, an embodiment of the present invention provides a data transmission processing method, comprising:

[0112] Step 101: The terminal determines the time-domain resource segmentation information and the frequency-domain resource segmentation information;

[0113] Here, time-domain resource segmentation information is used for resource segmentation in the time domain, and frequency-domain resource segmentation information is used for resource segmentation in the frequency domain.

[0114] In this step, the terminal determines the time-domain resource segmentation information and the frequency-domain resource segmentation information in order to execute the next step and segment the transmission resources.

[0115] Step 102: The terminal segments the transmission resources in the time domain and frequency domain respectively according to the time domain resource segmentation information and the frequency domain resource segmentation information to obtain multiple first resource segments.

[0116] In this step, the terminal segments the transmission resources in the time and frequency domains based on the time-domain resource segmentation information and frequency-domain resource segmentation information determined in step 101, resulting in multiple first resource segments. The time-domain and frequency-domain resource segmentation information determines the number of first resource segments.

[0117] Step 103: The terminal determines the second resource segment used for each segment of the data to be transmitted based on the plurality of first resource segments, and transmits the segmented data through the second resource segment.

[0118] Here, the data to be transmitted can be metadata bits, information bits, or a demodulation reference signal (DMRS), etc. The metadata bits (also called additional bits) are generated from the information bits, such as the last A bits of the information bits and the cyclic redundancy check bits of the information bits. The terminal segments the data to be transmitted, obtaining at least two data segments.

[0119] In this step, the terminal, based on the multiple first resource segments determined in step 102, determines the resource segment (i.e., the second resource segment) to be used for the transmission of each segment of the data to be transmitted, and uses the determined second resource segment to complete the transmission of the segmented data. Here, the number of second resource segments corresponds to the number of segmented data after the data to be transmitted is segmented.

[0120] Thus, following steps 101-103 above, for the segmented data to be transmitted, the terminal first segments the transmission resources in the time and frequency domains by determining the time-domain resource segmentation information and the frequency-domain resource segmentation information, obtaining multiple first resource segments. Then, it determines the second resource segment used to transmit each segmented data from these multiple first resource segments, and uses the second resource segment to complete the transmission of the segmented data. In this way, after segmenting the data to be transmitted, appropriate resource segments are used for transmission of the segmented data, reducing the number of bits transmitted each time, and the number of roots required is correspondingly reduced, thus reducing processing complexity. At the same time, the number of detections is reduced, improving detection performance.

[0121] For example, if the data to be transmitted has P bits, where P = 16, then in the case of transmitting the entire data, a 2... 16 = 65536 ZC sequences, requiring 839 ZC sequences and 400 different roots, while the receiving end needs to perform 400 correlation checks of length 839; in the case of segmented transmission, such as dividing into two segments, each 8 bits, each segment needs to construct 2 8 = 256 ZC sequences, requiring a ZC sequence of length 839 and 2 different roots, while the receiving end needs to perform 2 correlation detections of length 839, for a total of 4 correlation detections of length 839 for both segments.

[0122] It should be noted that the time-domain resource segmentation information and the frequency-domain resource segmentation information can be indicated by the network-side device. Therefore, optionally, step 101 includes:

[0123] The terminal receives time-domain resource segmentation information and frequency-domain resource segmentation information sent by the network-side device.

[0124] Of course, time-domain resource segmentation information and frequency-domain resource segmentation information can also be predefined or configured and stored in the terminal. The terminal can extract the required time-domain resource segmentation information and frequency-domain resource segmentation information for the data to be transmitted.

[0125] Optionally, in this embodiment, the time-domain resource segmentation information indicates N time-domain resource segments, where N is an integer greater than or equal to 2;

[0126] The frequency domain resource segmentation information indicates M frequency domain resource segments, where M is an integer greater than or equal to 2.

[0127] In other words, the terminal can divide resources into N segments in the time domain (time domain resource segmentation) according to time domain resource segmentation information, and divide resources into M segments in the time domain (frequency domain resource segmentation) according to frequency domain resource segmentation information. Therefore, the number of the first resource segments is N*M.

[0128] Optionally, two of the first resource segments with a time-domain interval less than a first threshold and a frequency-domain interval less than a fourth threshold satisfy one of the following conditions:

[0129] Continuous in the frequency domain; or,

[0130] They partially overlap in the frequency domain.

[0131] It should be noted that in this embodiment, if the time-domain interval between two first resource segments is less than a first threshold and the frequency-domain interval is less than a fourth threshold, it can be understood that these two first resource segments are frequency-adjacent. Whether these two first resource segments are continuous or partially overlapping in the frequency domain can be indicated by the frequency-domain resource segmentation information.

[0132] In this embodiment, the frequency domain length of the first resource segment can be all equal, such as all first resource segments having a frequency domain length of B. Of course, the frequency domain length of the first resource segment can also not be all equal, such as some first resource segments having a frequency domain length of B and other first resource segments having a frequency domain length of C.

[0133] For example, if N=4 and M=4, 16 first resource segments can be configured as follows: Figure 2As shown, each first resource segment has the same frequency domain length, and adjacent first resource segments (such as resource segment 11 and resource segment 22) are continuous in the frequency domain; for example, if N=3 and M=4, the 12 first resource segments can be arranged as follows: Figure 3 As shown, all first resource segments have the same frequency domain length, and adjacent first resource segments (such as resource segment 12 and resource segment 21) partially overlap in the frequency domain. This overlap can improve the detection performance of the receiver. For example, with N=3 and M=4, the 12 first resource segments can be arranged as follows: Figure 4 As shown, the frequency domain lengths of these 12 first resource segments are not all equal, and adjacent first resource segments (such as resource segment 11 and resource segment 21) partially overlap in the frequency domain.

[0134] Thus, in the first resource segment, the frequency domain segment location can be different in different time domain segments, meaning multiple frequency domain segments can be configured for each / group of time domain segments; the frequency domain segment location can also be different in different time domain segments, meaning each / group of time domain segments can be configured with a single frequency domain segment. This configuration can be performed by network-side devices, such as through frequency domain resource segment information.

[0135] It should be noted that when the frequency domain lengths of the first resource segment are not all equal, larger bandwidths can be allocated to the edge frequency domain segments, such as... Figure 4 The bandwidth of resource segments 21 and 33 is greater than that of resource segments 11 and 42.

[0136] In addition, in this embodiment, after determining the first resource segment, step 103 is executed to determine the second resource segment and transmit it.

[0137] Considering the impact of transmission between terminals, optionally, two second resource segments with a time-domain interval less than the first threshold satisfy one of the following conditions:

[0138] Continuous in the frequency domain; or,

[0139] They partially overlap in the frequency domain; or,

[0140] There exists a frequency domain interval smaller than the second threshold in the frequency domain.

[0141] Here, the two second resource segments can be understood as adjacent second resource segments. That is, the adjacent second resource segments determined by the terminal satisfy the following conditions: the time domain interval is less than the first threshold, and they are continuous or partially overlapping in the frequency domain or have a frequency domain interval less than the second threshold.

[0142] Optionally, the frequency domain range of the plurality of second resource segments corresponding to the data to be transmitted satisfies one of the following conditions within a time domain range of a preset length:

[0143] Occupy all subcarriers within the allocated bandwidth; or

[0144] Within the allocated bandwidth, the number of unoccupied subcarriers is less than the third threshold.

[0145] In other words, the second resource segment used by the segmented data to be transmitted will maximize the use of subcarriers within the allocated bandwidth within a preset time domain range. Here, the preset length can be determined based on the number of segmented data and the time domain length of the first resource segment.

[0146] Alternatively, in this embodiment, in step 103, the terminal determines a second resource segment for transmitting the segmented data based on the first resource segment, including:

[0147] The terminal acquires transmission resource segment patterns corresponding to the plurality of first resource segments; wherein, the transmission resource segment patterns are used to indicate the resource segments used for each segment of the data to be transmitted.

[0148] The terminal determines the second resource segment based on the transmission resource pattern.

[0149] In other words, the transmission resource segment pattern corresponds to the first resource segment, indicating the resource segment used for all segmented data transmissions of the data to be transmitted. When there is only one transmission resource segment pattern, each resource segment indicated by the transmission resource segment pattern is the second resource segment; when there are multiple transmission resource segment patterns, the terminal determines one transmission resource pattern, and each resource segment indicated by the transmission resource segment pattern is the second resource segment.

[0150] Thus, in this embodiment, in the transmission resource segment pattern, two resource segments with a time-domain interval less than the first threshold satisfy one of the following conditions:

[0151] Continuous in the frequency domain; or,

[0152] They partially overlap in the frequency domain; or,

[0153] There exists a frequency domain interval smaller than the second threshold in the frequency domain.

[0154] Here, the two resource segments can be understood as adjacent resource segments in the transmission resource segment pattern. That is to say, adjacent resource segments in the transmission resource segment pattern satisfy the following conditions: the time domain interval is less than the first threshold, and they are continuous or partially overlapping in the frequency domain or have a frequency domain interval less than the second threshold.

[0155] In the transmission resource segment pattern, the frequency domain range of all resource segments satisfies one of the following conditions within a preset length of time domain range:

[0156] Occupy all subcarriers within the allocated bandwidth; or

[0157] Within the allocated bandwidth, the number of unoccupied subcarriers is less than the third threshold.

[0158] This ensures that the second resource segment used by the segmented data to be transmitted will maximize the use of subcarriers within the allocated bandwidth within a preset time domain range.

[0159] Optionally, in this embodiment, the terminal acquires the transmission resource pattern corresponding to the first resource segment, including:

[0160] The terminal acquires the transmission resource segment pattern corresponding to the first resource segment; or...

[0161] The terminal generates a transmission resource segment pattern corresponding to the first resource segment by selecting frequency domain resource segments on different time domain resource segments.

[0162] Thus, on the one hand, the transmission resource segment pattern is pre-set to correspond to the first resource segment. For example, for an N*M first resource segment, multiple transmission resource segment patterns are pre-set, and the terminal can randomly determine a transmission resource segment pattern to determine the second resource segment used for transmitting segmented data.

[0163] For example, for Figure 2 The 16 first resource segments shown can be pre-set with the following transmission resource segment patterns: Figure 5 As shown, the second resource segment includes: first resource segment 11, first resource segment 22, first resource segment 34, and first resource segment 43; it can be as follows: Figure 6 As shown, the second resource segment includes: first resource segment 12, first resource segment 21, first resource segment 33, and first resource segment 44; it can be as follows: Figure 7 As shown, the second resource segment includes: first resource segment 13, first resource segment 24, first resource segment 32, and first resource segment 41; it can be as follows: Figure 8 As shown, the second resource segment includes: first resource segment 14, first resource segment 23, first resource segment 31, and first resource segment 42. For Figure 3 The 12 first resource segments shown can be pre-set with the following transmission resource segment patterns: Figure 9 As shown, the second resource segment includes: first resource segment 11, first resource segment 21, first resource segment 33, and first resource segment 42; it can be as follows: Figure 10 As shown, the second resource segment includes: first resource segment 12, first resource segment 22, first resource segment 31, and first resource segment 43; it can be as follows: Figure 11 As shown, the second resource segment includes: first resource segment 13, first resource segment 23, first resource segment 32, and first resource segment 41. For Figure 4 The 12 first resource segments shown can be pre-set with the following transmission resource segment patterns: Figure 12 As shown, the second resource segment includes: first resource segment 11, first resource segment 21, first resource segment 33, and first resource segment 42; it can be as follows: Figure 13 As shown, the second resource segment includes: first resource segment 12, first resource segment 22, first resource segment 31, and first resource segment 43; it can be as follows: Figure 14 As shown, the second resource segment includes: first resource segment 13, first resource segment 23, first resource segment 32, and first resource segment 41.

[0164] On the other hand, the transmission resource segment pattern is determined by the terminal itself. The terminal generates the transmission resource segment pattern corresponding to the first resource segment by selecting frequency domain resource segments on different time domain resource segments.

[0165] In the first time-domain resource segment, the frequency-domain resource segment can be selected based on the segmented data to be transmitted, or any frequency-domain resource segment can be selected arbitrarily. The selection of frequency-domain resource segments in subsequent time-domain resource segments needs to be determined based on the first resource segment selected in the previous step, ensuring that in the generated transmission resource segment pattern, two resource segments with a time-domain interval less than the first threshold are continuous or partially overlapping in the frequency domain, or have a frequency-domain interval less than the second threshold; and, the frequency domain range of all resource segments within the preset length of the time domain meets one of the following conditions: occupying all subcarriers within the allocated bandwidth, or the number of unoccupied subcarriers within the allocated bandwidth is less than the third threshold.

[0166] Assuming the terminal receives time-domain and frequency-domain resource segmentation information from the network-side device, and divides the resources according to this information as follows: Figure 2 The 16 first resource segments are shown. At this time, the data to be transmitted will not be transmitted repeatedly. The terminal performs the following steps:

[0167] 1) Select a frequency domain resource segment on the first time domain resource segment.

[0168] like Figure 5 As shown, the first resource segment 11 was selected; or, as... Figure 6 As shown, the first resource segment 12 was selected; or, as... Figure 7 As shown, the first resource segment 13 was selected; or, as... Figure 8 As shown, the first resource segment 14 was selected.

[0169] 2) Select the frequency domain resource segment on the next time domain resource segment.

[0170] like Figure 5 As shown, the first resource segment 22 was selected (the first resource segment 22 and the first resource segment 11 are continuous in the frequency domain and their time interval is less than the first threshold); as Figure 6 As shown, the first resource segment 21 was selected (the first resource segment 21 and the first resource segment 12 are continuous in the frequency domain and their time interval is less than the first threshold); as Figure 7As shown, the first resource segment 24 was selected (the first resource segment 24 and the first resource segment 13 are continuous in the frequency domain and their time interval is less than the first threshold); as Figure 8 As shown, the first resource segment 23 was selected (the first resource segment 23 and the first resource segment 14 are continuous in the frequency domain and the time interval is less than the first threshold).

[0171] 3) Repeat step 2) until the frequency domain resource segment selection on each time domain resource segment is completed.

[0172] Among them, such as Figure 5 As shown, the terminal will select a frequency domain resource segment in the fourth time domain resource segment (the time domain interval between the fourth time domain resource segment and the second time domain resource segment is less than the first threshold), namely the first resource segment 43, which is continuous in the frequency domain with the first resource segment 22; and select a frequency domain resource segment in the third time domain resource segment, namely the first resource segment 34, which is continuous in the frequency domain with the first resource segment 43. Figure 6 As shown, the terminal selects a frequency domain resource segment in the third time domain resource segment (the time domain interval between the third time domain resource segment and the first time domain resource segment is less than a first threshold), namely the first resource segment 33, which is continuous with the first resource segment 12 in the frequency domain; and selects a frequency domain resource segment in the fourth time domain resource segment, namely the first resource segment 44, which is continuous with the first resource segment 33 in the frequency domain. Figure 7 As shown, the terminal selects a frequency domain resource segment in the third time domain resource segment (the time domain interval between the third time domain resource segment and the first time domain resource segment is less than a first threshold), namely the first resource segment 32, which is continuous in the frequency domain with the first resource segment 13; and selects a frequency domain resource segment in the fourth time domain resource segment, namely the first resource segment 41, which is continuous in the frequency domain with the first resource segment 32. Figure 8 As shown, the terminal will select a frequency domain resource segment in the fourth time domain resource segment (the fourth time domain resource segment and the second time domain resource segment are less than the first threshold), namely the first resource segment 42, which is continuous with the first resource segment 23 in the frequency domain; and select a frequency domain resource segment in the third time domain resource segment, namely the first resource segment 31, which is continuous with the first resource segment 42 in the frequency domain.

[0173] 4) Repeat steps 1)-3) until all transport resource segment patterns are obtained.

[0174] In this embodiment, considering the continuity performance of time-domain resource segmentation and frequency-domain resource segmentation, and to avoid transmission interference caused by different transmission resource segment patterns used between terminals, as shown in the example above, the terminal repeats steps 1)-3) four times to obtain the transmission resource segment pattern: Figures 5-8Other combinations of first resource segments cannot achieve a balance between the performance of transmitting resource segment patterns.

[0175] Of course, for Figure 3 The first resource segment shown can be generated autonomously by the terminal using a similar method described above. Figures 9-11 The diagram shows the transmission resource segment pattern; for Figure 4 The first resource segment shown can be generated autonomously by the terminal using a similar method described above. Figures 12-14 The diagram of the transmission resource segment shown will not be described again here.

[0176] Optionally, in this embodiment, when the data to be transmitted needs to be transmitted repeatedly, the second resource segment used by the same segmented data has the same frequency domain segment position at different time domain segment positions.

[0177] For example, if the data to be transmitted is divided into four segments, the second resource segment to be used, as determined above, is as follows: Figure 6 As shown, the terminal can transmit segmented data 1 on the first resource segment 12, segmented data 2 on the first resource segment 21, segmented data 3 on the first resource segment 33, and segmented data 4 on the first resource segment 44. If the data to be transmitted needs to be transmitted repeatedly, the terminal will follow the instructions... Figure 6 The location of the second resource segment, as shown, will transmit four more data segments.

[0178] It should be understood that the method of this embodiment of the invention is applicable to non-coordinated non-orthogonal multiple access (MOA) transmission scenarios. Specifically, when a terminal needs to transmit metadata bits and information bits, the method of this embodiment is used to transmit the metadata bits. In this case, if the bandwidth occupied by transmitting the metadata bits is the same as the bandwidth occupied by transmitting the information bits, and the subcarrier spacing used for transmitting the metadata bits is the same as the subcarrier spacing used for transmitting the information bits, then the network-side device can detect the ZC sequence used for transmitting the metadata bits, and then use this ZC sequence as the DMRS required for transmitting the information bits. The ZC sequence can be used to simultaneously complete the functions of metadata bit segmentation transmission and DMRS transmission.

[0179] In this embodiment, the first threshold, the second threshold, the third threshold, and the fourth threshold are predefined or configured by the system or network-side device.

[0180] In summary, the method of this invention reduces processing complexity and improves detection performance through segmented transmission; moreover, the segmented data (referring to ZC sequences) maximizes the allocated bandwidth in the frequency domain so that the detected segmented data can be used as DMRS for subsequent data transmission to complete the channel estimation function.

[0181] like Figure 15As shown, embodiments of the present invention also provide a data transmission processing method, including:

[0182] Step 1501: The network-side device determines the time-domain resource segmentation information and the frequency-domain resource segmentation information;

[0183] Here, time-domain resource segmentation information is used for resource segmentation in the time domain, and frequency-domain resource segmentation information is used for resource segmentation in the frequency domain. In this step, the network-side device determines the time-domain resource segmentation information and the frequency-domain resource segmentation information in order to execute the next step. Of course, the network-side device can also send this time-domain resource segmentation information and the frequency-domain resource segmentation information to the terminal so that the terminal can determine the resource segments used for segmented data transmission of the data to be transmitted.

[0184] Step 1502: The network-side device segments the transmission resources in the time domain and frequency domain respectively according to the time domain resource segmentation information and the frequency domain resource segmentation information to obtain multiple first resource segments.

[0185] In this step, the network-side device segments the transmission resources in the time and frequency domains according to the time-domain resource segmentation information and frequency-domain resource segmentation information determined in step 1501, resulting in multiple first resource segments. The time-domain resource segmentation information and frequency-domain resource segmentation information determine the number of first resource segments.

[0186] Step 1503: The network-side device obtains the transmission resource segment pattern corresponding to the plurality of first resource segments; wherein, the transmission resource segment pattern is used to indicate the resource segment used for each segment of data transmission to be transmitted.

[0187] In this step, the network-side device obtains the transmission resource segment pattern for use based on the multiple first resource segments determined in step 1502, in order to execute the next step.

[0188] Step 1504: The network-side device performs data detection based on the transmission resource segment pattern.

[0189] In this step, the network-side device performs data detection based on the transmission resource segment pattern obtained in step 1503 to complete the reception of terminal-side data.

[0190] In this way, following the steps described above, the network-side device first segments the transmission resources in the time and frequency domains by determining the time-domain resource segmentation information and the frequency-domain resource segmentation information, obtaining multiple first resource segments. Then, it obtains the transmission resource segment pattern corresponding to these multiple first resource segments. Thus, it performs data detection based on the transmission resource segment pattern to avoid missing data reception when the second resource segment used by the unknown terminal is being transmitted. Moreover, since the segmented data is transmitted using the appropriate resource segment, the number of bits transmitted each time is reduced, and the required root is correspondingly reduced. Detection based on the transmission resource segment pattern also reduces the complexity of reception detection. Similarly, the number of detections is reduced, improving detection performance.

[0191] It should be understood that, in this embodiment, the network-side device can group terminals that use the same transmission resource segment pattern to complete data transmission into the same group of terminals. For example, using... Figure 5 The terminals transmitting segmented data shown in the transmission resource segment diagram are the first group of terminals; using... Figure 6 The terminal transmitting segmented data in the transmission resource segment diagram shown is the second group of terminals; it uses... Figure 7 The terminal transmitting segmented data in the transmission resource segment diagram shown is the third group of terminals; it uses... Figure 8 The terminal transmitting segmented data in the transmission resource segment diagram shown is the fourth group of terminals.

[0193] Continuous in the frequency domain; or,

[0194] They partially overlap in the frequency domain; or,

[0195] There exists a frequency domain interval smaller than the second threshold in the frequency domain.

[0196] Optionally, in the transmission resource segment pattern, the frequency domain range of all resource segments satisfies one of the following conditions within a preset length of time domain range:

[0199] Optionally, the network-side device acquires the transmission resource segment pattern corresponding to the first resource segment, including:

[0200] The network-side device obtains the transmission resource segment pattern corresponding to the first resource segment; or...

[0201] The network-side device generates a transmission resource segment pattern corresponding to the first resource segment by selecting frequency domain resource segments on different time domain resource segments.
