Communication method and related apparatus

Abstract

A communication method and a related device. In the method, after receiving first information indicating at least one first resource, a first communication apparatus can send, on the basis of the first resource, first uplink data that is actually repeatedly transmitted N times, and the first uplink data of part or all of the N times of actual repeated transmissions is obtained by means of a first orthogonal sequence. In this way, repeatedly transmitted uplink data sent by different first communication apparatuses can be obtained by means of performing processing on the basis of different orthogonal sequences; correspondingly, after receiving different uplink data, a second communication apparatus can differentiate the uplink data sent by the different first communication apparatuses on the basis of the different orthogonal sequences. Therefore, the method for processing uplink data by means of orthogonal sequences makes it possible for different first communication apparatuses to reuse the same resources to realize data transmission, so as to support multi-user multiplexing, and thus the capacity of a system can be improved.

Description

Communication method and related apparatus

[0001] The present application claims priority from the Chinese patent application No. 202410481946.8 filed on April 19, 2024, and entitled "A communication method and related apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and in particular to a communication method and related apparatus. BACKGROUND

[0003] Wireless communication can be transmission communication between two or more communication nodes without propagation through a conductor or cable, and the communication nodes generally include network devices and terminal devices.

[0004] At present, different communication devices can use repeated transmission to improve the success rate of data reception. For example, in the uplink communication process, the terminal device can use repeated uplink data transmission to improve the success rate of receiving the uplink data by the network device. Although this method can improve the success rate of receiving the uplink data sent by a certain terminal device by the network device, the transmission resources of the uplink data occupied by the same terminal device will increase. For example, for a certain terminal device, if the terminal device repeatedly transmits uplink data twice, it means that the terminal device needs twice the resources of a single transmission of uplink data to complete the transmission of uplink data. This method will lead to a decrease in system capacity.

[0005] Therefore, how to improve the system capacity during data transmission is a technical problem to be solved. SUMMARY

[0006] The present application provides a communication method and related apparatus for improving system capacity.

[0007] The first aspect of the present application provides a communication method, which is performed by a first communication device. The first communication device can be a communication apparatus (e.g., a terminal device), or the first communication device can be a part of the communication apparatus (e.g., a processor, a chip, a chip system, or the like), or the first communication device can also be a logic module or software that can realize all or part of the functions of the communication apparatus. In the method, the first communication device receives first information, the first information being used to indicate at least one first resource, the first resource being used to carry N times of actual repeated transmission of uplink data, N being an integer greater than 1; the first communication device transmits the first uplink data of the N times of actual repeated transmission; in a time domain resource occupied by any one of M times of actual repeated transmission in the N times of actual repeated transmission, the first P time units are obtained through first orthogonal sequence processing, P being a positive integer, and M being a positive integer less than or equal to N.

[0008] Based on the above scheme, after receiving the first information indicating the at least one first resource, the first communication device can transmit the first uplink data of the N times of actual repeated transmission based on the first resource, and the first uplink data of part or all of the N times of actual repeated transmission is obtained through the first orthogonal sequence. In this way, the uplink data of the repeated transmission transmitted by different first communication devices can be obtained based on different orthogonal sequences, and accordingly, the second communication device can distinguish the uplink data transmitted by different first communication devices based on different orthogonal sequences after receiving the different uplink data. Therefore, through the processing mode of the uplink data based on the orthogonal sequence, different first communication devices can multiplex the same resource to realize data transmission, so as to support multi-user multiplexing and improve system capacity.

[0009] The second aspect of the present application provides a communication method, which is performed by a second communication device. The second communication device can be a communication apparatus (e.g., a network device), or the second communication device can be a part of the communication apparatus (e.g., a processor, a chip, a chip system, or the like), or the second communication device can also be a logic module or software that can realize all or part of the functions of the communication apparatus. In the method, the second communication device transmits first information, the first information being used to indicate at least one first resource, the first resource being used to carry N times of actual repeated transmission of uplink data, N being an integer greater than 1; the second communication device receives part or all of the first uplink data of the N times of actual repeated transmission; in a time domain resource occupied by any one of M times of actual repeated transmission in the N times of actual repeated transmission, the first P time units are obtained through first orthogonal sequence processing, P being a positive integer, and M being a positive integer less than or equal to N.

[0010] Based on the above scheme, after the second communication device sends the first information indicating the at least one first resource, the second communication device can receive part or all of the M times of actually repeated first uplink data based on the first resource, and the M times of actually repeated first uplink data are obtained through the first orthogonal sequence. In this way, the repeated uplink data sent by different first communication devices can be obtained based on different orthogonal sequences, and accordingly, the second communication device can distinguish the uplink data sent by different first communication devices based on different orthogonal sequences after receiving the different uplink data. Therefore, through the processing manner of the uplink data based on the orthogonal sequence, different first communication devices can multiplex the same resource to implement data transmission, so as to support multi-user multiplexing and improve system capacity.

[0011] In addition, in the time domain resource occupied by any one of the M times of actual repeated transmission in the N times of actual repeated transmission, the first P time units are obtained through the first orthogonal sequence. In this way, different communication devices can implement multi-user multiplexing based on the first P time units in the time domain resource occupied by any one of the actual repeated transmissions, which can avoid the situation that multi-user multiplexing is unavailable due to different numbers of time domain units occupied by different actual repeated transmissions, and can reduce the implementation complexity of the first uplink data of the M times of actual repeated transmission.

[0012] Optionally, the time domain unit can be a symbol, a time slot, etc.

[0013] It should be noted that the first information can be used to indicate the at least one first resource, and when the first information indicates two or more first resources, any first resource can implement the processing process of the uplink data based on the orthogonal sequence through the above scheme, which can implement multi-user multiplexing on more resources to further improve system capacity.

[0014] Optionally, the first resource can be used to carry Q (Q is a positive integer) times of nominal repeated transmission, and at least one of the following conditions is met:

[0015] The time domain resource occupied by the qth nominal repeated transmission in the Q times of nominal repeated transmission is different from the time domain resource occupied by the qth nominal repeated transmission in the N times of actual repeated transmission, q is 1 to Q;

[0016] In the Q times of nominal repeated transmission, the number of time domain units occupied by any two actual repeated transmissions is the same, the index of the time domain start symbol occupied is the same, and the index of the time domain end symbol occupied is the same;

[0017] In the Q times of nominal repeated transmission, the time domain resource occupied by any actual repeated transmission is located in the same time slot;

[0018] In the N actual repeated transmissions, the time domain resources occupied by 0 or at least one actual repeated transmission are located in two or more different time slots respectively;

[0019] In the N actual repeated transmissions, the number of time domain units occupied by at least two actual repeated transmissions is different;

[0020] In the N actual repeated transmissions, the indexes of the time domain start symbols occupied by at least two actual repeated transmissions are different; or

[0021] In the N actual repeated transmissions, the indexes of the time domain end symbols occupied by at least two actual repeated transmissions are different.

[0022] Optionally, the first orthogonal sequence (for example, the value of one or more elements contained in the first orthogonal sequence, the sequence length of the first orthogonal sequence, etc.) can be configured by the network device, or can be pre-configured by the standard / protocol.

[0023] In a possible implementation of the first aspect or the second aspect, the M actual repeated transmissions satisfy at least one of the following:

[0024] Mode 1. The number of time domain units occupied by each actual repeated transmission in the M actual repeated transmissions is greater than a first threshold (the first threshold is less than or equal to P);

[0025] Mode 2. The M actual repeated transmissions are the M actual repeated transmissions with the largest number of occupied time domain units in the N actual repeated transmissions; or,

[0026] Mode 3. The number difference of two time domain units occupied by any two (or any two adjacent in time domain) actual repeated transmissions in the M actual repeated transmissions is less than (or equal to) a second threshold.

[0027] Based on the above scheme, when mode 1 is satisfied, in the M actual repeated transmissions for multi-user multiplexing, the number of time domain units occupied by any actual repeated transmission is greater than (or equal to) the first threshold, that is, the repeated transmissions with a number of occupied time domain units less than the first threshold in the N actual repeated transmissions can not be used for multi-user multiplexing. In this way, the limitation of the repeated transmissions with a small number of time domain units on the number of time domain units for multi-user multiplexing can be reduced.

[0028] When mode 2 is satisfied, the M actual repeated transmissions for multi-user multiplexing are the M actual repeated transmissions with the largest number of occupied time domain units in the N actual repeated transmissions, that is, the N-M actual repeated transmissions with a small number of occupied time domain units in the N actual repeated transmissions can not be used for multi-user multiplexing.

[0029] In the case of satisfying the manner 3, the number difference of two time domain units occupied by any two actual repeated transmissions in the M actual repeated transmissions for multi-user multiplexing is less than the second threshold value, so that the first communication device can implement data transmission through multi-user multiplexing in the actual repeated transmissions with similar number of time domain units, and the limitation of the repeated transmission with less number of time domain units on the number of time domain units for multi-user multiplexing can be reduced.

[0030] In addition, in the case of satisfying any one of the manners 1 to 3, the transmission mode of multi-user multiplexing can be implemented as much as possible by using the repeated transmission with more number of time domain units, and multi-user multiplexing can be implemented on more resources to further improve the system capacity.

[0031] Optionally, the first threshold value and the second threshold value can be configured by the network device or preconfigured by the standard / protocol.

[0032] In a possible implementation manner of the first aspect or the second aspect, the value of M is determined based on the number of repeated transmissions of the nominal repeated transmission. For example, the number of repeated transmissions of the nominal repeated transmission is T, and M is determined based on T. For example, M is a multiple (for example, the multiple is 1, 2, 0.5, etc.) of T.

[0033] For example, the first information includes the index of the M actual repeated transmissions (for example, the index of the M actual repeated transmissions in the N actual repeated transmissions, the index of the time domain resources occupied by the M actual repeated transmissions, etc.).

[0034] Based on the above scheme, the first communication device can determine the value of M and / or the index of the M actual repeated transmissions based on the received information / signaling / message, so as to reduce the implementation complexity of the first communication device.

[0035] Optionally, any one of the value of M and the index of the M actual repeated transmissions can be configured by the network device through other information or preconfigured by the standard / protocol.

[0036] In a possible implementation manner of the first aspect or the second aspect, the redundancy versions corresponding to the first uplink data of the M actual repeated transmissions are the same.

[0037] Based on the above scheme, the M actual repeated transmissions for multi-user multiplexing can use the same redundancy version, so that the second communication device can perform mutual checking based on the data of different actual repeated transmissions, so as to improve the success rate of the second communication device in analyzing the first uplink data.

[0038] Optionally, the redundancy versions corresponding to the first uplink data of at least two of the M actual repeated transmissions can be different. Different redundancy versions can be obtained through different encoding methods, so that the second communication device can parse the same first uplink data based on different redundancy versions, thereby improving the reliability of data transmission.

[0039] The third aspect of the present application provides a communication method, which is performed by a first communication device. The first communication device can be a communication device (such as a terminal device), or the first communication device can be a part of the communication device (such as a processor, a chip, or a chip system, etc.), or the first communication device can also be a logic module or software that can realize all or part of the functions of the communication device. In the method, the first communication device receives second information, the second information being used to indicate a second resource, the second resource being used to carry X times of repeated transmission of uplink data, X being an integer greater than 1; the first communication device transmits X times of repeated transmission of second uplink data, the X times of repeated transmission of second uplink data being obtained through processing of a second orthogonal sequence; wherein the second resource includes X sub-resources with the same number of time domain units, the i-th repeated transmission of second uplink data in the X times of repeated transmission of second uplink data being carried in the i-th sub-resource in the X sub-resources, i being 1 to X; in the time domain, the X sub-resources are continuous except for a third resource, the third resource including unavailable time domain resources.

[0040] Based on the above scheme, after receiving the second information indicating the second resource, the first communication device can transmit X times of repeated transmission of second uplink data based on the second resource, and the X times of repeated transmission of second uplink data is obtained through a second orthogonal sequence. In this way, the repeated transmission of uplink data transmitted by different first communication devices can be obtained based on different orthogonal sequences, and accordingly, the second communication device can distinguish the uplink data transmitted by different first communication devices based on different orthogonal sequences after receiving the different uplink data. Therefore, through the processing of the uplink data by the orthogonal sequence, different first communication devices can multiplex the same resource to realize data transmission, thereby supporting multi-user multiplexing and improving system capacity.

[0041] The fourth aspect of the present application provides a communication method, which is performed by a second communication device. The second communication device can be a communication apparatus (e.g., a network device), or the second communication device can be a part of the communication apparatus (e.g., a processor, a chip, a chip system, or the like), or the second communication device can also be a logic module or software that can realize all or part of the functions of the communication apparatus. In the method, the second communication device transmits second information, which is used to indicate a second resource, and the second resource is used to carry X times of repeated transmission of uplink data, where X is an integer greater than 1. The second communication device receives X times of repeated transmission of second uplink data, and the X times of repeated transmission of the second uplink data is obtained through a second orthogonal sequence. The second resource includes X sub-resources with the same number of time domain units, and the i th repeated transmission of the second uplink data in the X times of repeated transmission of the second uplink data is carried in the i th sub-resource in the X sub-resources, where i is 1 to X. In the time domain, the X sub-resources are continuous except for a third resource, and the third resource includes unavailable time domain resources.

[0042] Based on the above scheme, after the second communication device transmits the second information indicating the second resource, the first communication device can receive part or all of the X times of repeated transmission of the second uplink data based on the second resource, and the X times of repeated transmission of the second uplink data is obtained through the second orthogonal sequence. In this way, the repeated transmission of the uplink data transmitted by different first communication devices can be obtained based on different orthogonal sequences, and accordingly, the second communication device can distinguish the uplink data transmitted by different first communication devices based on different orthogonal sequences after receiving the different uplink data. Therefore, through the processing mode of the uplink data based on the orthogonal sequence, different first communication devices can multiplex the same resource to realize data transmission, support multi-user multiplexing, and improve system capacity.

[0043] In addition, in the second resource, the number of time domain units of the X sub-resources used for multi-user multiplexing is the same, and in the time domain, the X sub-resources are continuous except for the third resource including unavailable time domain resources. In this way, the complexity of determining the X sub-resources can be reduced, and the processing complexity of the X times of repeated transmission of the second uplink data can also be reduced.

[0044] Optionally, the second resource can be used to carry Q (Q is a positive integer) times of nominal repeated transmission, and at least one of the following conditions is met:

[0045] The time domain resources occupied by the q th nominal repeated transmission in the Q times of nominal repeated transmission are different from the time domain resources occupied by the q th nominal repeated transmission in the X times of repeated transmission, where q is 1 to Q.

[0046] In the Q nominal repeated transmissions, any two actual repeated transmissions occupy the same number of time domain units, occupy the same index of time domain start symbol, and occupy the same index of time domain end symbol.

[0047] In the Q nominal repeated transmissions, the time domain resources occupied by any actual repeated transmission are located in the same time slot.

[0048] In the X repeated transmissions, the time domain resources occupied by 0 or at least one actual repeated transmission are located in two or more different time slots, respectively.

[0049] In the X repeated transmissions, the indexes of time domain start symbols occupied by at least two actual repeated transmissions are different.

[0050] In the X repeated transmissions, the indexes of time domain end symbols occupied by at least two actual repeated transmissions are different.

[0051] Optionally, the X repeated transmissions can be X actual repeated transmissions.

[0052] In a possible implementation of the third aspect or the fourth aspect, in the time domain, one or more time domain units contained in any of the X sub-resources are consecutive.

[0053] Based on the above scheme, in the second resource, the time domain units contained in any of the X sub-resources for multi-user multiplexing can be consecutive. In this way, the uplink data of each repeated transmission can be carried on consecutive time units, it can be ensured that the same repetition is transmitted through consecutive time units, and the processing complexity of the uplink data carried by the same repetition can be reduced.

[0054] In a possible implementation of the third aspect or the fourth aspect, the number of time domain units contained in any of the X sub-resources is Y, Y is a positive integer; and the third resource further includes available time domain resources, and the number of consecutive time domain units contained in the available time domain resources is less than Y in the time domain.

[0055] Based on the above scheme, different sub-resources in the X sub-resources can be separated by the third resource, and the third resource can include available time domain resources with a number of time domain units less than Y in addition to the unavailable time domain resources, that is, the X sub-resources for multi-user multiplexing can skip the unavailable time domain resources and the time domain resources with a small number of consecutive time domain units. In this way, it can be ensured that one or more time domain units contained in any of the X sub-resources are consecutive.

[0056] In a possible implementation of the third aspect or the fourth aspect, in the time domain, the at least two time domain resources contained in at least one of the X sub-resources are separated by unavailable time domain resources, and each of the at least two time domain resources contains one or more continuous time domain units.

[0057] Based on the above scheme, in the second resource, in at least one of the X sub-resources for multi-user multiplexing, at least two time domain resources are separated by unavailable time domain resources, and each of the at least two time domain resources contains one or more continuous time domain units. In this way, the uplink data of the repeated transmission can be carried by the at least two discontinuous time domain units, so as to utilize the available time domain resources as much as possible, thereby improving the resource utilization.

In the technical solutions provided in the embodiments of the present application, the device for implementing the function of the network device is taken as an example to describe the technical solutions provided in the embodiments of the present application.

[0098] (3) Configuration and pre-configuration: In the present application, configuration and pre-configuration will be used simultaneously. Configuration refers to that the network device sends some parameter configuration information or parameter values to the terminal device through messages or signaling, so that the terminal device determines the communication parameters or transmission resources according to the values or information. Pre-configuration is similar to configuration, which can be parameter information or parameter values agreed by the network device and the terminal device in advance, or parameter information or parameter values adopted by the network device or the terminal device according to standard protocols, or parameter information or parameter values pre-stored in the network device or the terminal device. The present application does not limit this.

[0099] Further, these values and parameters can be changed or updated.

[0100] (4) The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "At least one" means one or more, and "multiple" means two or more. "And / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the cases of A alone, A and B together, and B alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects. "At least one of the following" or similar expressions means any combination of these items, including any combination of single item or multiple items. For example, "at least one of A, B and C" includes A, B, C, AB, AC, BC or ABC. In addition, unless otherwise specified, the ordinal numbers "first", "second", etc. mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, time sequence, priority or importance of the multiple objects.

[0101] (5) In embodiments of the present application, "sending" and "receiving" represent the direction of signal transmission. For example, "sending information to XX" can be understood as that the destination of the information is XX, which can include direct sending through the air interface, or indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as that the source of the information is YY, which can include direct receiving from YY through the air interface, or indirect receiving from YY through the air interface by other units or modules. "Sending" can also be understood as "output" of a chip interface, and "receiving" can also be understood as "input" of a chip interface.

[0102] In other words, sending and receiving can be between devices, such as between network devices and terminal devices, or within devices, such as between components, modules, chips, software modules or hardware modules within a device through a bus, wire or interface.

[0103] It can be understood that the information can be processed as necessary between the source and the destination of the information transmission, such as encoding and modulation, but the destination can understand the valid information from the source. Similar expressions in the present application can be similarly understood and will not be repeated here.

[0104] (6) In embodiments of the present application, "indicating" can include direct indication and indirect indication, and can also include explicit indication and implicit indication. The information indicated by a certain information (indication information as described below) is referred to as to-be-indicated information. In the implementation process, there are many ways to indicate the to-be-indicated information, for example but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be indicated only by a part of the to-be-indicated information, and the other part of the to-be-indicated information is known or agreed in advance, for example, the arrangement order of each information can be used to indicate a specific information, thereby reducing the indication overhead to a certain extent. The present application does not limit the specific manner of indication. It can be understood that for the sender of the indication information, the indication information can be used to indicate the to-be-indicated information, and for the receiver of the indication information, the indication information can be used to determine the to-be-indicated information.

In various embodiments in this application, and various methods / designs / implementation manners in each embodiment, if there is no special description and no logical conflict, the terms and / or descriptions among different embodiments, and among various methods / designs / implementation manners in each embodiment are consistent, and can be mutually referred to, and the technical features in different embodiments, and in various methods / designs / implementation manners in each embodiment can be combined to form new embodiments, methods, or implementation manners according to their inherent logical relationship. The implementation manners of the present application described below do not constitute a limitation on the protection scope of the present application.

[0106] The present application can be applied to a long term evolution (LTE) system, a new radio (NR) system, or a new radio vehicle to everything (NR V2X) system; can also be applied to a system in which LTE and 5G are hybrid networked; or a device-to-device (D2D) communication system, a machine to machine (M2M) communication system, an Internet of Things (IoT), or a drone communication system; or a communication system supporting multiple wireless technologies, such as a communication system supporting LTE technology and NR technology; or a non-ground communication system, such as a satellite communication system, a high-altitude communication platform, and the like. In addition, the communication system can also be applied to a narrow band-internet of things (NB-IoT) system, an enhanced data rate for GSM evolution (EDGE) system, a wideband code division multiple access (WCDMA) system, a code division multiple access 2000 (CDMA2000) system, a time division-synchronization code division multiple access (TD-SCDMA) system, and a future-oriented communication technology. Or other communication systems, wherein the communication system includes a network device and a terminal device, the network device as a configuration information sending entity, and the terminal device as a configuration information receiving entity. Specifically, there are entities in the communication system that send configuration information to another entity, and send data to another entity or receive data sent by another entity; another entity receives configuration information and sends data to the configuration information sending entity or receives data sent by the configuration information sending entity according to the configuration information. Wherein, the present application can be applied to a terminal device in a connected state or an active state, and can also be applied to a terminal device in an inactive state or an idle state.

[0107] Referring to FIG. 1, an architecture diagram of a communication system 1000 to which embodiments of the present application are applied is shown. As shown in FIG. 1, the communication system includes a radio access network (RAN) 100 and a core network 200. Optionally, the communication system 1000 can further include an Internet 300. The RAN 100 includes at least one RAN node (e.g., 110a and 110b in FIG. 1, collectively referred to as 110) and at least one terminal (e.g., 120a-120j in FIG. 1, collectively referred to as 120). The RAN 100 can further include other RAN nodes, such as a wireless relay device and / or a wireless backhaul device (not shown in FIG. 1). The terminal 120 is connected to the RAN node 110 in a wireless manner, and the RAN node 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the RAN node 110 in the RAN 100 can be independent and different physical devices, or can be the same physical device integrated with the logical functions of the core network device and the logical functions of the RAN node. Terminals and terminals, and RAN nodes and RAN nodes can be connected to each other in a wired or wireless manner.

[0108] It should be noted that the technical solutions of the embodiments of the present application are applicable to a ground communication system. Alternatively, the technical solutions of the embodiments of the present application are applicable to a communication system integrating ground communication and satellite communication, which can also be referred to as a non-terrestrial network (NTN) communication system. For example, the RAN 100 in FIG. 1 can include a ground base station, wherein the ground base station can include a TN cell (i.e., the signals of the TN cell can be transmitted and received by the ground base station); and the RAN 100 in FIG. 1 can further include a non-ground base station, for example, a satellite, which can include an NTN cell (i.e., the signals of the NTN cell can be transmitted and received by the satellite). The ground communication system can be, for example, a long term evolution (LTE) system, a universal mobile telecommunication system (UMTS), a 5G communication system, a new radio (NR) system, or a next-generation communication system of the 5G communication system, etc., which is not limited herein.

[0109] Satellite communication has wider coverage, communication cost is independent of transmission distance, and can overcome natural geographical obstacles such as oceans, deserts, and mountains, compared with traditional mobile communication systems. In order to overcome the shortcomings of traditional communication networks, satellite communication can be an effective supplement to traditional networks. It is generally believed that, compared with ground network communication, non-ground network communication has different channel characteristics, such as large transmission delay and large Doppler frequency offset. For example, the round-trip delay of GEO satellite communication is 238-270 milliseconds (ms). The round-trip delay of LEO satellite communication is 8-20 ms. According to the orbital height, satellite communication systems can be divided into three types: high-orbit (geostationary earth orbit, GEO) satellite communication systems, also known as synchronous orbit satellite systems; medium-orbit (medium earth orbit, MEO) satellite communication systems; and low-orbit (low earth orbit, LEO) satellite communication systems.

[0110] The GEO satellite is also commonly known as a geostationary satellite, and the orbital height can be 35,786 kilometers (km). The main advantage is that it is relatively stationary relative to the ground and provides a large coverage area. However, the GEO satellite also has relatively prominent disadvantages: the distance from the earth is too large, requiring a large-diameter antenna; the transmission delay is large, about 0.5 seconds, which cannot meet the needs of real-time services; and the orbital resources are relatively scarce, the launch cost is high, and coverage cannot be provided for polar regions. The MEO satellite has an orbital height of 2,000-35,786 km, and a relatively small number of satellites can achieve global coverage, but the transmission delay is higher than that of the LEO satellite. It is mainly used for positioning and navigation. In addition, the orbital height of 300-2,000 km is called a low-orbit satellite (LEO). The LEO satellite has a lower orbital height than the MEO and GEO satellites, a smaller data propagation delay, less power loss, and a relatively lower launch cost. Therefore, the LEO satellite communication network has made great progress in recent years and has attracted attention.

[0111] In one possible implementation, the satellite device can be divided into a transparent mode and a regenerative mode according to the working mode.

[0112] The two modes will be described below by way of example with reference to the implementation modes shown in FIGS. 2a, 2b, 2c, and 2d.

[0113] In the implementation mode of the transparent mode shown in FIG. 2a, the satellite and the gateway (i.e., NTN Gateway in FIG. 2a) act as a relay, that is, the remote radio unit shown in FIG. 2a, and the communication between the terminal device and the gNB needs to be realized through the relay process. In other words, in the transparent mode, the satellite has the function of relay forwarding.

[0114] For example, in the implementation mode of the transparent mode shown in FIG. 2b, when the satellite (including GEO satellite, MEO satellite, LEO satellite, etc.) works in the transparent mode, the satellite has the function of relay forwarding. The gateway has the function of the base station or part of the base station function, at this time, the gateway can be regarded as the base station. Alternatively, the base station can be deployed separately from the gateway, and then the delay of the feeder link includes the delay of the satellite to the gateway and the delay of the gateway to the gNB.

[0115] Optionally, the transparent mode can be taken as an example that the gateway and the gNB are together or close to each other, and for the case that the gateway is far away from the gNB, the delay of the feeder link can be obtained by adding the delay of the satellite to the gateway and the delay of the gateway to the gNB.

[0116] In the implementation mode of the regenerative mode shown in FIG. 2c, the satellite and the gateway (i.e., NTN Gateway in FIG. 2c) act as the gNB, and can communicate with the terminal device. In other words, in the regenerative mode, the satellite has the function of the base station or part of the base station function, at this time, the satellite can be regarded as the base station.

[0117] For example, in the implementation mode of the regenerative mode shown in FIG. 2d, when the satellite (including GEO satellite, MEO satellite, LEO satellite, etc.) works in the regenerative mode, compared with the implementation mode shown in FIG. 2b, the satellite has the function of the base station or part of the base station function, at this time, the satellite can be regarded as the base station (i.e., the air base station).

[0118] Optionally, in FIG. 2b and / or FIG. 2d, the satellite can be realized by other means, such as the unmanned aerial vehicle or the high-altitude platform in the figure.

[0119] It should be noted that the base stations of the NTN and the ground network can be interconnected through a common core network. Higher timeliness assistance and interconnection can also be realized through the interface defined between the base stations. In NR, the interface between the base stations is called Xn interface, and the interface between the base station and the core network is called NG interface. In the fusion network, the NTN node and the ground node can realize interworking and cooperation through the foregoing interfaces.

[0120] It should be noted that the present application can be applied to a long term evolution (LTE) system, a new radio (NR) system, or a communication system evolved after 5G (for example, 6G, 7G, etc.).

[0121] Taking 5G as an example, a 5G satellite communication system architecture is shown in FIG. 3. The ground terminal device accesses the 5G new radio access network, and the 5G base station is deployed on the satellite and connected to the ground core network through a wireless link. At the same time, there is a wireless link between the satellites to complete the signaling interaction and user data transmission between base stations. The description of the devices and interfaces in FIG. 3 is as follows:

[0122] 5G core network: user access control, mobility management, session management, user security authentication, charging and other services. It is composed of multiple functional units and can be divided into control plane and data plane functional entities. The access and mobility management unit (AMF) is responsible for user access management, security authentication, and mobility management. The user plane unit (UPF) is responsible for managing user plane data transmission, traffic statistics, and other functions. The session management function (SMF) is mainly used for session management in the mobile network, such as session establishment, modification, and release.

[0123] Ground station: responsible for forwarding signaling and service data between satellite base stations and 5G core network.

[0124] 5G new radio: wireless link between terminal and base station.

[0125] Xn interface: interface between 5G base stations and base stations, mainly used for signaling interaction such as handover.

[0126] NG interface: interface between 5G base station and 5G core network, mainly interacting with non-access layer (NAS) signaling of core network and user service data.

[0127] In addition, the network device in the ground network communication system and the satellite in the NTN communication system can be regarded as a network device. The apparatus for implementing the function of the network device can be the network device, or can be an apparatus capable of supporting the network device to implement the function, such as a chip system, which can be installed in the network device. In the following description of the technical solutions provided by the embodiments of the present application, the apparatus for implementing the function of the network device is taken as an example of the satellite to describe the technical solutions provided by the embodiments of the present application. It can be understood that when the method provided by the embodiments of the present application is applied to the ground network communication system, the actions performed by the satellite can be applied to the base station or the network device to perform.

[0128] In the embodiments of the present application, the apparatus for implementing the function of the terminal device can be the terminal device, or can be an apparatus capable of supporting the terminal device to implement the function, such as a chip system, which can be installed in the terminal device. In the embodiments of the present application, the chip system can be composed of a chip, or can include the chip and other discrete devices. In the technical solutions provided by the embodiments of the present application, the apparatus for implementing the function of the terminal device is taken as an example of the terminal or the UE to describe the technical solutions provided by the embodiments of the present application.

[0129] In addition, the satellite described above can be a stationary satellite, a non-stationary satellite, an artificial satellite, a low-orbit satellite, a medium-orbit satellite, and a high-orbit satellite, etc., which is not specifically limited herein.

[0130] The above describes various scenarios of wireless communication involved in the present application. It should be understood that the above is only an exemplary description of the scenarios in which the present application can be applied, and the present application can also be applied to other application scenarios, which are not limited herein. The wireless communication process involved in the present application will be described below.

[0131] In the communication system shown in FIG. 1 / FIG. 2a / FIG. 2b / FIG. 2c / FIG. 2d / FIG. 3, the signal (for example, the signal carries configuration information / configuration signaling, etc.) that can be sent by the network device can configure the communication resource. The communication resource can include the communication resource of the network device, and the communication resource of the adjacent network device that can exist, so that the receiver of the signal can determine the corresponding communication resource based on the signal. For example, in the case that the receiver of the signal is a terminal device, the terminal device can obtain network service based on the communication resource.

[0132] Currently, between different communication devices, the success rate of data reception can be improved through repeated transmission. For example, in the uplink communication process, the terminal device can transmit repeated uplink data to improve the success rate of receiving the uplink data by the network device. Among them, the uplink data can be carried under the physical uplink shared channel (PUSCH). In the following, two repetition modes in the current standard will be introduced through some implementation examples.

[0133] Type A (Type A) repetition. In the time domain, Type A repetition can occupy one or more slots, and the symbol position occupied by the repeated part of the data in each slot is the same, that is, in each slot, the symbol start point of data transmission and the number of symbols occupied are the same.

[0134] As shown in FIG. 4a, it is an example of Type A repetition. In FIG. 4a, taking two of the one or more slots occupied by Type A repetition as an example, they are slot 1 and slot 2, and the number of symbols in the two slots is 14. In addition, the network device can configure the starting symbol position of each repetition as symbol 5 and configure the duration of each repetition as 6 symbols; accordingly, the terminal device can perform repeated transmission at symbol 5 to symbol 10 of each slot.

[0135] Type B (Type B) repetition. In the time domain, Type B repetition has two concepts of nominal repetition and actual repetition. Among them, the configuration of nominal repetition can include the duration of each repetition, the number of nominal repetitions; and the actual repetition can be adjusted according to the actual transmission situation, wherein the symbol length of different actual repetition transmissions can be different, for example, downlink (D) symbols, invalid symbols and slot boundaries, etc. will divide a nominal repetition into one or more actual transmissions. In addition, actual repetition with only 1 symbol can be omitted.

[0136] As shown in FIG. 4b, it is an example of Type B repetition. In FIG. 4b, taking two of the one or more slots occupied by Type B repetition as an example, they are slot 1 and slot 2, and the number of symbols in the two slots is 14. In addition, the network device can configure the nominal repetition configuration to include the duration of each repetition as 6 symbols and the number of nominal repetitions as 4, and the four nominal repetitions are as follows:

[0137] Nominal repetition 1, occupying symbols 1 to 6 in slot 1;

[0138] Nominal repetition 2, occupying symbols 7-12 in time slot 1;

[0139] Nominal repetition 3, occupying symbols 13-14 in time slot 1 and symbols 1-4 in time slot 2;

[0140] Nominal repetition 4, occupying symbols 5-10 in time slot 2.

[0141] In addition, in the example shown in FIG. 4b, based on the criterion of actual transmission described above, each nominal repetition can correspond to one or more actual transmissions, including:

[0142] For nominal repetition 1, symbols 3 and 6 in time slot 1 are D symbols, and accordingly, nominal repetition 1 corresponds to actual repetition 1 and actual repetition 2;

[0143] For nominal repetition 2, symbols 7 and 8 in time slot 1 are unusable symbols, and accordingly, nominal repetition 2 corresponds to actual repetition 3;

[0144] For nominal repetition 3, the time slot boundary between time slot 1 and time slot 2 will split the same nominal repetition, and accordingly, nominal repetition 3 corresponds to actual repetition 4 and actual repetition 5;

[0145] For nominal repetition 4, symbol 6 in time slot 2 is a D symbol, and symbols 7 and 8 in time slot 2 are unusable symbols, and accordingly, nominal repetition 4 corresponds to actual repetition 6 and actual repetition 7; wherein actual repetition 6 occupies 1 symbol, i.e., the actual repetition 6 can not transmit data.

[0146] As can be seen from the above process, although the way of repeatedly transmitting data can improve the success rate of receiving uplink data transmitted by a terminal device by a network device, the transmission resources of uplink data occupied by the same terminal device will increase. For example, for a terminal device, the number of repetitions of uplink data repeatedly transmitted by the terminal device is 2, which means that 2 times the resources of single transmission of uplink data of the terminal device are needed to complete the transmission of uplink data, which will lead to a decrease in system capacity. Therefore, how to improve the system capacity in the data transmission process is a technical problem to be solved.

[0147] To solve the above problem, the present application provides a communication method and related devices, which will be described in detail below in conjunction with the accompanying drawings.

[0148] Please refer to FIG. 5, which is an implementation diagram of a communication method provided by the present application, the method comprising the following steps.

[0149] It should be noted that in the following, the first communication device and the second communication device in FIG. 5 and FIG. 7 are taken as an example to illustrate the execution subject of the interaction, but the application does not limit the execution subject of the interaction. For example, the communication device can be a communication equipment (such as a terminal equipment or a network equipment), or a chip, a baseband chip, a modem chip, a system on chip (SoC) chip containing a modem core, a system in package (SIP) chip, a communication module, a chip system, a processor, a logic module or software in the communication equipment, etc. Wherein, the first communication device can be a terminal equipment and the second communication device can be a network equipment.

[0150] S501. The second communication device sends first information, and correspondingly, the first communication device receives the first information. Wherein, the first information is used to indicate at least one first resource, and the first resource is used to carry N times of actual repeated transmission of uplink data, and N is an integer greater than 1.

[0151] S502. The first communication device sends N times of actual repeated transmission of first uplink data, and correspondingly, the second communication device receives part or all of the N times of actual repeated transmission of the first uplink data. Wherein, in the time domain resource occupied by any one of M times of actual repeated transmission in the N times of actual repeated transmission, the first P time units are obtained by processing a first orthogonal sequence, P is a positive integer, and M is a positive integer less than or equal to N. In other words, the time domain resource occupied by any one of M times of actual repeated transmission is a resource for multi-user multiplexing.

[0152] It should be noted that since transmission errors may occur in signal transmission, therefore, after the first communication device sends N times of repeated transmission of the first uplink data, the second communication device can receive part or all of the N times of repeated transmission of the first uplink data.

[0153] Optionally, the first resource can be used to carry Q (Q is a positive integer) times of nominal repeated transmission. The nominal repeated transmission and the actual repeated transmission can refer to the description of the foregoing FIG. 4a, FIG. 4b and the related implementation examples. Exemplarily, the Q times of nominal repeated transmission and the N times of actual repeated transmission can satisfy one or more of the following:

[0154] The time domain resource occupied by the qth nominal repeated transmission in the Q times of nominal repeated transmission is different from the time domain resource occupied by the qth nominal repeated transmission in the N times of actual repeated transmission, q is 1 to Q;

[0155] In the Q nominal repeated transmissions, the number of time domain units occupied by any two actual repeated transmissions is the same, the index of the time domain starting symbol occupied is the same, and the index of the time domain ending symbol occupied is the same.

[0156] In the Q nominal repeated transmissions, the time domain resources occupied by any actual repeated transmission are located in the same time slot.

[0157] In the N actual repeated transmissions, the time domain resources occupied by zero or at least one actual repeated transmission are located in two or more different time slots, respectively.

[0158] In the N actual repeated transmissions, the number of time domain units occupied by at least two actual repeated transmissions is different.

[0159] In the N actual repeated transmissions, the index of the time domain starting symbol occupied by at least two actual repeated transmissions is different; or

[0160] In the N actual repeated transmissions, the index of the time domain ending symbol occupied by at least two actual repeated transmissions is different.

[0161] Optionally, the first orthogonal sequence (for example, the value of one or more elements contained in the first orthogonal sequence, the sequence length of the first orthogonal sequence, etc.) can be configured by the network device or pre-configured by the standard / protocol.

[0162] Optionally, the first orthogonal sequence can be one of L (L is greater than 1) orthogonal sequences, and the L orthogonal sequences can be used to realize resource multiplexing, where resource multiplexing means that multiple users send information / signaling / data in the same resource to improve resource utilization and system capacity, and the information / signaling / data sent by each user is processed by one of the L orthogonal sequences. For example, the length of the orthogonal sequence is 2 (i.e. L = 2), and the two groups of sequences are {1, 1} and {1, -1}. Taking two terminal devices as an example, the two terminal devices respectively use the two groups of sequences to expand and repeat the data, which can ensure that they transmit in the same time-frequency resource but do not interfere with each other. For example, the transmission signal s1 of UE1 is expanded to {s1*a1, s1*a2} by using the sequence {a1, a2}, and the transmission signal s2 of UE2 is expanded to {s2*b1, s2*b2} by using the sequence {b1, b2}. UE1 and UE2 both send their own signals in the same resource, and the receiver can use the sequence {a1, a2} to solve the signal s1 and the sequence {b1, b2} to solve the signal s2.

[0163] As an example, the length of the orthogonal sequence is 4 (i.e. L = 4), as shown in Table 2.

[0164] Table 2

[0165] In Table 2, taking L = 4 as an example, the L orthogonal sequences can include part or all of the sequence [+1+1+1+1] with index 0, the sequence [+1-j-1+j] with index 1, the sequence [+1-1+1-1] with index 2, and the sequence [+1+j-1-j] with index 2. Correspondingly, the first orthogonal sequence used by the first communication apparatus in step S502 can be one of the sequences in Table 2.

[0166] As another example, the orthogonal sequences with length 2 (i.e., L = 2) are shown in Table 3.

[0167] Table 3

[0168] In Table 3, taking L = 2 as an example, the L orthogonal sequences can include the sequence [+1+1] with index 0 and the sequence [+1-1] with index 1. Correspondingly, the first orthogonal sequence used by the first communication apparatus in step S502 can be one of the sequences in Table 3.

[0169] Optionally, the L orthogonal sequences can be indicated by the network device to the first communication apparatus (e.g., indicated by a broadcast message), or preconfigured by a protocol / standard, which is not limited herein.

[0170] In this application, the orthogonal sequence can be replaced by other terms, such as orthogonal code, orthogonal information, orthogonal matrix, orthogonal spreading code, orthogonal spreading sequence, or orthogonal cover code, etc.

[0171] In a possible implementation, in the implementation process shown in FIG. 5, the redundancy versions corresponding to the first uplink data of the M actual repeated transmissions are the same. In other words, the M actual repeated transmissions for multi-user multiplexing can use the same redundancy version, so that the second communication apparatus can check each other based on the data of different actual repeated transmissions, to improve the success rate of the second communication apparatus in parsing the first uplink data.

[0172] Optionally, the redundancy versions corresponding to the first uplink data of at least two actual repeated transmissions of the M actual repeated transmissions can be different. Different redundancy versions can be obtained by different encoding methods, so that the second communication apparatus parses the same first uplink data based on different redundancy versions, to improve the reliability of data transmission.

[0173] Based on the scheme shown in FIG. 5, after the first communication device receives the first information indicating at least one first resource in step S501, the first communication device can transmit N times of actual repeated transmissions of the first uplink data based on the first resource in step S502, and part or all of the actual repeated transmissions of the first uplink data in the N times of actual repeated transmissions are obtained through the first orthogonal sequence. In this way, the repeated transmission of the uplink data transmitted by different first communication devices can be obtained based on different orthogonal sequences, and accordingly, the second communication device can distinguish the uplink data transmitted by different first communication devices based on different orthogonal sequences after receiving the different uplink data. Therefore, through the processing manner of the uplink data based on the orthogonal sequence, different first communication devices can multiplex the same resource to implement data transmission, so as to support multi-user multiplexing (i.e., the resource of M times of actual repeated transmissions is a resource for multi-user multiplexing), and the system capacity can be improved.

[0174] In addition, in the time domain resource occupied by any one of the M times of actual repeated transmissions in the N times of actual repeated transmissions, the first P time units are obtained through the first orthogonal sequence. In this way, different communication devices can implement multi-user multiplexing based on the first P time units in the time domain resource occupied by any one of the actual repeated transmissions, which can avoid the situation that multi-user multiplexing is unavailable due to different numbers of time domain units occupied by different actual repeated transmissions, and the implementation complexity of the first uplink data of the M times of actual repeated transmissions can be reduced.

[0175] It should be noted that the first information can be used to indicate at least one first resource, and when the first information indicates two or more first resources, any first resource can implement the processing process of the uplink data based on the orthogonal sequence through the above scheme, and multi-user multiplexing can be implemented on more resources to further improve the system capacity.

[0176] In a possible implementation, the M times of actual repeated transmissions transmitted by the first communication device in step S502, and the time domain resource occupied by any one of the M times of actual repeated transmissions can be a resource for multi-user multiplexing. When any one of the following modes 1 to 3 is met, the transmission mode of multi-user multiplexing using the repeated transmission with a larger number of time domain units as much as possible can be used, and multi-user multiplexing can be implemented on more resources to further improve the system capacity. The following will be introduced respectively.

[0177] Mode 1. The number of time domain units occupied by each of the M times of actual repeated transmissions is greater than a first threshold (the first threshold is less than or equal to P).

[0178] Optionally, since the number of time domain units occupied by the nominal repeated transmission is configured by the network device to the terminal device, for this purpose, the manner 1 can be replaced by that the ratio of the number of time domain units occupied by each of the M actual repeated transmissions to the number of time domain units occupied by the nominal repeated transmission is greater than the threshold A.

[0179] Optionally, the first threshold, the threshold A (and other thresholds that may appear later, such as the second threshold) can be configured by the network device, or can be pre-configured by the standard / protocol.

[0180] Specifically, when the manner 1 is met, in the M actual repeated transmissions for multi-user multiplexing, the number of time domain units occupied by any actual repeated transmission is greater than (or equal to) the first threshold, that is, the repeated transmission in the N actual repeated transmissions occupies the number of time domain units less than the first threshold, which can not be used for multi-user multiplexing. In this way, the limitation of the repeated transmission with less number of time domain units on the number of time domain units for multi-user multiplexing can be reduced.

[0181] As an example, taking the scenario shown in FIG. 6a as an example. In FIG. 6a, on the time slots 1 to 4, a total of 4 nominal repeated transmissions are included, and the duration of each repetition is 12 symbols, and the four nominal repetitions are as follows:

[0182] Nominal repetition 1, occupying symbols 1 to 12 in time slot 1;

[0183] Nominal repetition 2, occupying symbols 13 to 14 in time slot 1, and symbols 1 to 10 in time slot 2;

[0184] Nominal repetition 3, occupying symbols 11 to 14 in time slot 2, and symbols 1 to 8 in time slot 3;

[0185] Nominal repetition 4, occupying symbols 9 to 14 in time slot 3, and symbols 1 to 6 in time slot 3.

[0186] In addition, in the example shown in FIG. 6a, based on the criteria for actual transmission described above, each nominal repetition can correspond to one or more actual transmissions, including:

[0187] For nominal repetition 1, nominal repetition 1 corresponds to actual repetition 1;

[0188] For nominal repetition 2, the time slot boundary of time slot 1 and time slot 2 will split the same nominal repetition, accordingly, nominal repetition 2 corresponds to actual repetition 2 and actual repetition 3;

[0189] For nominal repetition 3, the time slot boundary of time slot 2 and time slot 3 will split the same nominal repetition, accordingly, nominal repetition 3 corresponds to actual repetition 4 and actual repetition 5;

[0190] For nominal repetition 4, the slot boundary of slot 3 and slot 4 will split the same nominal repetition, and accordingly, nominal repetition 3 corresponds to actual repetition 6 and actual repetition 7.

[0191] According to the above implementation, when the method shown in FIG. 5 is applied to the scenario shown in FIG. 6a, the N actual repetition transmissions can be 7 (N = 7) repetition transmissions in FIG. 6a, and the number of time domain units occupied by the N actual repetitions is:

[0192] The actual repetition 1 occupies 12 time domain symbols.

[0193] The actual repetition 2 occupies 2 time domain symbols.

[0194] The actual repetition 3 occupies 10 time domain symbols.

[0195] The actual repetition 4 occupies 4 time domain symbols.

[0196] The actual repetition 5 occupies 8 time domain symbols.

[0197] The actual repetition 6 occupies 6 time domain symbols.

[0198] The actual repetition 7 occupies 6 time domain symbols.

[0199] In the case of satisfying the above manner 1, different actual repetitions can be screened based on a first threshold to determine M actual repetition transmissions.

[0200] As an example, taking the first threshold as 2 or 3, since the actual repetition 2 occupies 2 time domain symbols, the actual repetition 2 will not be selected as the M actual repetition transmissions, i.e., the actual repetition 2 is not used for multi-user multiplexing. Correspondingly, the number of time domain symbols occupied by the other actual repetitions is greater than the first threshold, so the M actual repetition transmissions can be actual repetition 1, actual repetition 3 to actual repetition 7, a total of 6 actual repetition transmissions. Thus, the minimum number of symbols on the M time domain resources corresponding to the M actual repetition transmissions is 4, which can support multi-user multiplexing data transmission on 4 symbols.

[0201] Similarly, taking the threshold A as 1 / 6, since the ratio of the number of time domain symbols occupied by the actual repetition 2 to the number of time domain symbols of the nominal repetition transmission is 1 / 6, the actual repetition 2 will not be selected as the M actual repetition transmissions, i.e., the actual repetition 2 is not used for multi-user multiplexing. Correspondingly, the ratio of the number of time domain symbols occupied by the other actual repetitions to the number of time domain symbols of the nominal repetition transmission is greater than the threshold A, so the M actual repetition transmissions can be actual repetition 1, actual repetition 3 to actual repetition 7, a total of 6 actual repetition transmissions.

[0202] As shown in FIG. 6b, in the scenario shown in FIG. 6a, the time domain symbols filled with patterns represent time domain symbols used for multi-user multiplexing, i.e., actual repetition 1, actual repetition 3 to actual repetition 7 can be used for multi-user multiplexing. Thus, on the M time domain resources corresponding to M actual repetition transmissions, the minimum number of symbols is 4 (i.e., P can be 4), which can support multi-user multiplexed data transmission on 4 symbols.

[0203] As another example, taking the first threshold value of 4 or 5 as an example, since the number of time domain symbols occupied by actual repetition 2 is 2 and the number of time domain symbols occupied by actual repetition 4 is 4, actual repetition 2 and actual repetition 4 will not be selected as M actual repetition transmissions, i.e., actual repetition 2 and actual repetition 4 are not used for multi-user multiplexing. Correspondingly, the number of time domain symbols occupied by other actual repetition transmissions is greater than the first threshold value, so M actual repetition transmissions can be actual repetition 1, actual repetition 3, actual repetition 5 to actual repetition 7, a total of 5 actual repetition transmissions.

[0204] Similarly, taking the threshold value A of 1 / 3 as an example, since the ratio of the number of time domain symbols occupied by actual repetition 2 to the number of time domain symbols of nominal repetition transmission is 1 / 6 and the ratio of the number of time domain symbols occupied by actual repetition 4 to the number of time domain symbols of nominal repetition transmission is 1 / 3, actual repetition 2 and actual repetition 4 will not be selected as M actual repetition transmissions, i.e., actual repetition 2 and actual repetition 4 are not used for multi-user multiplexing. Correspondingly, the ratio of the number of time domain symbols occupied by other actual repetitions to the number of time domain symbols of nominal repetition transmission is greater than the threshold value A, so M actual repetition transmissions can be actual repetition 1, actual repetition 3, actual repetition 5 to actual repetition 7, a total of 5 actual repetition transmissions.

[0205] As shown in FIG. 6c, in the scenario shown in FIG. 6a, the time domain symbols filled with patterns represent time domain symbols used for multi-user multiplexing, i.e., actual repetition 1, actual repetition 3, actual repetition 5 to actual repetition 7 can be used for multi-user multiplexing. Thus, on the M time domain resources corresponding to M actual repetition transmissions, the minimum number of symbols is 6 (i.e., P can be 6), which can support multi-user multiplexed data transmission on 6 symbols.

[0206] From the above process, if multi-user multiplexing transmission mode is used in N actual repetition transmissions, it will be limited by some actual repetitions with fewer occupied time domain units (for example, in the scenario shown in FIG. 6a, multi-user multiplexing can only be performed on time domain resources with a symbol length of 2 in 7 actual repetition transmissions), which greatly limits the performance gain of multi-user multiplexing. In the case of mode 1, the limitation of smaller symbol number on the symbol number of multi-user multiplexing can be reduced to improve the performance gain of multi-user multiplexing.

[0207] Option 2. The M actual repeated transmissions are M actual repeated transmissions with the largest number of occupied time domain units in the N actual repeated transmissions.

[0208] Specifically, when the option 2 is satisfied, the M actual repeated transmissions for the multi-user multiplexing are M actual repeated transmissions with the largest number of occupied time domain units in the N actual repeated transmissions, i.e., N-M actual repeated transmissions with the smaller number of occupied time domain units in the N actual repeated transmissions can not be used for the multi-user multiplexing.

[0209] Optionally, the value of M is determined based on a repetition number of the nominal repeated transmission. For example, the repetition number of the nominal repeated transmission is T, and M is determined based on T. For example, M is a multiple of T (e.g., the multiple is 1, 2, 0.5, etc.).

[0210] Optionally, the first information received by the first communication device in step S501 includes an index of the M actual repeated transmissions (e.g., an index of the M actual repeated transmissions in the N actual repeated transmissions, an index of time domain resources occupied by the M actual repeated transmissions, etc.).

[0211] Therefore, the first communication device can determine the value of M and / or the index of the M actual repeated transmissions based on the received information / signaling / message, so as to reduce the implementation complexity of the first communication device.

[0212] Optionally, any one of the value of M and the index of the M actual repeated transmissions can be configured by a network device through other information, or can be pre-configured by a standard / protocol.

[0213] As an example, the method shown in FIG. 5 is applied to the case where the scenario shown in FIG. 6a, the N actual repeated transmissions can be 7 (N=7) repeated transmissions in FIG. 6a.

[0214] For example, when the value of M is 6, the M actual repeated transmissions can be 6 actual repeated transmissions with the largest number of occupied time domain units in the N actual repeated transmissions, i.e., actual repeated 1, actual repeated 3 to actual repeated 7 shown in FIG. 6b can be used for the multi-user multiplexing. Therefore, the minimum number of symbols on the M time domain resources corresponding to the M actual repeated transmissions is 4 (i.e., P can be 4), which can support data transmission for multi-user multiplexing on 4 symbols.

[0215] For example, when M is 5, the M actual repeated transmissions can be the 5 actual repeated transmissions with the largest number of occupied time domain units in the N actual repeated transmissions, i.e., actual repetition 1, actual repetition 3, actual repetition 5 to actual repetition 7 in FIG. 6c can be used for multi-user multiplexing. Thus, the minimum number of symbols on the M time domain resources corresponding to the M actual repeated transmissions is 6 (i.e., P can be 6), which can support data transmission with multi-user multiplexing on 4 symbols.

[0216] From the above process, if multi-user multiplexing is used in all N actual repeated transmissions, it will be limited by some actual repetitions with a small number of occupied time domain units (e.g., in the scenario shown in FIG. 6a, multi-user multiplexing can only be performed on time domain resources with a symbol length of 2 in 7 actual repeated transmissions). This greatly limits the performance gain of multi-user multiplexing. In the case of satisfying mode 2, multi-user multiplexing can be performed on a larger number of repeated symbols, which can reduce the limitation of repeated symbols with a small number of symbols on the number of symbols for multi-user multiplexing, thereby improving the performance gain of multi-user multiplexing.

[0217] Mode 3. The difference between the number of two time domain units occupied by any two (or any two adjacent in time domain) actual repeated transmissions in the M actual repeated transmissions is less than (or equal to) a second threshold.

[0218] Specifically, when mode 3 is satisfied, in the M actual repeated transmissions for multi-user multiplexing, the difference between the number of two time domain units occupied by any two actual repeated transmissions is less than the second threshold, so that the first communication device can perform data transmission through multi-user multiplexing in actual repeated transmissions with similar number of time domain units, and can reduce the limitation of repeated transmissions with a small number of time domain units on the number of time domain units for multi-user multiplexing.

[0219] As an example, the method shown in FIG. 5 is applied to the scenario shown in FIG. 6a, and the N actual repeated transmissions carried by the first resource can be 7 (N=7) repeated transmissions in FIG. 6a.

[0220] For example, when the value of the second threshold is 8, since the difference between the number of time domain symbols occupied by actual repetition 2 and the number of time domain symbols occupied by actual repetition 1 is 10 (greater than 8), actual repetition 2 is not used for multi-user multiplexing. Correspondingly, the difference between the number of time domain symbols occupied by any two actual repeated transmissions is less than or equal to the second threshold. Therefore, the M actual repeated transmissions can be actual repetition 1, actual repetition 3 to actual repetition 7, a total of 6 actual repeated transmissions. Thus, the minimum number of symbols on the M time domain resources corresponding to the M actual repeated transmissions is 4, which can support data transmission with multi-user multiplexing on 4 symbols.

[0221] As another example, the method shown in FIG. 5 is applied to the case where the scenario shown in FIG. 6a, the first information can indicate a plurality of first resources, each of which contains a repetition number N. Taking the 7 times of repeated transmission in FIG. 6a as an example, the first information can indicate 3 first resources as follows:

[0222] First resource_1: actual repetition 1 and actual repetition 2;

[0223] First resource_2: actual repetition 3 and actual repetition 4;

[0224] First resource_3: actual repetition 5 and actual repetition 6.

[0225] As shown in the example of FIG. 6d, in the case of satisfying mode 3, taking the value of the second threshold as 8 for example, the M times of actual repeated transmission in each first resource is as follows:

[0226] For the first resource_1, since the difference between the number of time domain symbols occupied by the actual repetition 2 and the number of time domain symbols occupied by the actual repetition 1 is 10 (greater than 8), that is, the actual repetition 1 and the actual repetition 2 are not used for multi-user multiplexing. In other words, in the first resource_1, the first communication device does not use the mode of multi-user multiplexing for transmission.

[0227] For the first resource_2, since the difference between the number of time domain symbols occupied by the actual repetition 3 and the number of time domain symbols occupied by the actual repetition 4 is 6 (less than 8), that is, the actual repetition 3 and the actual repetition 4 are used for multi-user multiplexing. In other words, in the first resource_2, the first communication device can use the mode of multi-user multiplexing for transmission, and the number of symbols for multi-user multiplexing in each actual repetition can be the minimum symbol number (that is, the symbol number of the actual repetition 4 is 4, that is, P=4).

[0228] For the first resource_3, since the difference between the number of time domain symbols occupied by the actual repetition 5 and the number of time domain symbols occupied by the actual repetition 5 is 2 (less than 8), that is, the actual repetition 5 and the actual repetition 6 are used for multi-user multiplexing. In other words, in the first resource_3, the first communication device can use the mode of multi-user multiplexing for transmission, and the number of symbols for multi-user multiplexing in each actual repetition can be the minimum symbol number (that is, the symbol number of the actual repetition 6 is 6, that is, P=6).

[0229] As another example, mode 1 and mode 3 can be used in combination. For example, the method shown in FIG. 5 is applied to the case where the scenario shown in FIG. 6a, the first information can indicate a plurality of first resources, each of which contains a repetition number N. Taking the 7 times of repeated transmission in FIG. 6a as an example, in the case of satisfying mode, the first information can indicate 3 first resources as follows:

[0230] First resource_1: actual repetition 1 and actual repetition 3;

[0231] First resource_2: actual repetition 4 and actual repetition 5;

[0232] First resource_3: actual repetition 6 and actual repetition 7.

[0233] As shown in the example of FIG. 6e, in the case of satisfying the mode 3, taking the value of the second threshold as 8 for example, the M actual repetition transmissions in each first resource are as follows:

[0234] For the first resource_1, since the difference between the number of time domain symbols occupied by the actual repetition 3 and the number of time domain symbols occupied by the actual repetition 1 is 2 (less than 8), that is, the actual repetition 1 and the actual repetition 3 are used for multi-user multiplexing. In other words, in the first resource_1, the first communication device can use the multi-user multiplexing mode for transmission, and the number of symbols for multi-user multiplexing in each actual repetition can be the minimum symbol number (that is, the symbol number of the actual repetition 3 is 10, that is, P = 10).

[0235] For the first resource_2, since the difference between the number of time domain symbols occupied by the actual repetition 4 and the number of time domain symbols occupied by the actual repetition 5 is 4 (less than 8), that is, the actual repetition 4 and the actual repetition 5 are used for multi-user multiplexing. In other words, in the first resource_2, the first communication device can use the multi-user multiplexing mode for transmission, and the number of symbols for multi-user multiplexing in each actual repetition can be the minimum symbol number (that is, the symbol number of the actual repetition 4 is 4, that is, P = 4).

[0236] For the first resource_3, since the difference between the number of time domain symbols occupied by the actual repetition 6 and the number of time domain symbols occupied by the actual repetition 7 is 0 (less than 8), that is, the actual repetition 6 and the actual repetition 7 are used for multi-user multiplexing. In other words, in the first resource_3, the first communication device can use the multi-user multiplexing mode for transmission, and the number of symbols for multi-user multiplexing in each actual repetition can be the minimum symbol number (that is, the symbol number of the actual repetition 6 or the actual repetition 7 is 6, that is, P = 6).

[0237] From the above process, if the multi-user multiplexing transmission mode is used in all N actual repetition transmissions, it will be limited by some actual repetitions with fewer occupied time domain units (for example, in the scenario shown in FIG. 6a, multi-user multiplexing can only be performed on time domain resources with a symbol length of 2 in 7 actual repetition transmissions), which greatly limits the performance gain of multi-user multiplexing. In the case of satisfying the mode 3, multi-user multiplexing can be performed on repetitions with more symbols, which can reduce the limitation of repetitions with smaller symbol numbers on the number of symbols for multi-user multiplexing, thereby improving the performance gain of multi-user multiplexing.

[0238] Referring to FIG. 7, an implementation of the communication method provided in the present application is shown, which comprises the following steps.

[0239] S701. The second communication device sends second information, and the first communication device receives the second information. The second information is used to indicate a second resource, and the second resource is used to carry X times of repeated transmission of uplink data, where X is an integer greater than 1.

[0240] S702. The first communication device sends X times of repeated transmission of second uplink data, and the second communication device receives part or all of the X times of repeated transmission of second uplink data. The X times of repeated transmission of second uplink data is obtained by processing with a second orthogonal sequence; the second resource comprises X sub-resources with the same number of time domain units, the i-th repeated transmission of second uplink data in the X times of repeated transmission of second uplink data is carried in the i-th sub-resource in the X sub-resources, i is 1 to X; in the time domain, the X sub-resources are continuous except for a third resource, and the third resource comprises unavailable time domain resources.

[0241] It should be noted that due to the possibility of transmission errors in signal transmission, after the first communication device sends X times of repeated transmission of second uplink data, the second communication device can receive part or all of the X times of repeated transmission of second uplink data.

[0242] Optionally, the second resource can be used to carry Q (Q is a positive integer) times of nominal repeated transmission. The nominal repeated transmission can refer to the description of the foregoing FIG. 4a, FIG. 4b and related implementation examples. Exemplarily, the Q times of nominal repeated transmission and the X times of repeated transmission can satisfy one or more of the following:

[0243] The time domain resources occupied by the q-th nominal repeated transmission in the Q times of nominal repeated transmission are different from the time domain resources occupied by the q-th nominal repeated transmission in the X times of repeated transmission, q is 1 to Q;

[0244] In the Q times of nominal repeated transmission, the number of time domain units occupied by any two actual repeated transmissions is the same, the index of the starting symbol of the time domain occupied is the same, and the index of the ending symbol of the time domain occupied is the same;

[0245] In the Q times of nominal repeated transmission, the time domain resources occupied by any actual repeated transmission are located in the same time slot;

[0246] In the X times of repeated transmission, the time domain resources occupied by 0 times or at least one actual repeated transmission are respectively located in two or more different time slots;

[0247] In the X times of repeated transmissions, indexes of time domain starting symbols occupied by at least two actual repeated transmissions are different; or

[0248] In the X times of repeated transmissions, indexes of time domain ending symbols occupied by at least two actual repeated transmissions are different.

[0249] Optionally, the X times of repeated transmissions can be X times of actual repeated transmissions, that is, the X times of actual repeated transmissions can refer to the implementation process of the Type B transmission described above. Alternatively, the X times of repeated transmissions can be different from the X times of actual repeated transmissions, that is, the X times of actual repeated transmissions can be different from the implementation process of the Type B transmission described above, for example, the X times of repeated transmissions can be a newly defined type of repeated transmission, for example, Type C (Type C).

[0250] For example, the transmission parameter can include one or more of the following: a type of resource mapping, a type of data repetition, a starting point of data transmission, a number of time units occupied by one repetition, and a number of repetitions.

[0251] In a possible implementation, in the implementation process shown in FIG. 7, the redundancy versions corresponding to the second uplink data of the X times of actual repeated transmissions are the same. In other words, the X times of actual repeated transmissions for multi-user multiplexing can use the same redundancy version, so that the second communication device can perform mutual checking based on the data of different actual repeated transmissions, to improve the success rate of the second communication device in parsing the second uplink data.

[0252] Optionally, the redundancy versions corresponding to the second uplink data of at least two actual repeated transmissions in the X times of actual repeated transmissions can be different, different redundancy versions can be obtained through different encoding modes, so that the second communication device parses the same second uplink data based on different redundancy versions, to improve the reliability of data transmission.

[0253] Based on the scheme shown in FIG. 7, after the first communication device receives the second information indicating the second resource in step S701, in step S702, the first communication device can transmit X times repeated transmission of the second uplink data based on the second resource, and the X times repeated transmission of the second uplink data is obtained by the second orthogonal sequence. In this way, the repeated transmission of the uplink data transmitted by different first communication devices can be obtained based on different orthogonal sequences, and accordingly, the second communication device can distinguish the uplink data transmitted by different first communication devices based on different orthogonal sequences after receiving the different uplink data. Therefore, by the processing manner of the uplink data based on the orthogonal sequence, different first communication devices can multiplex the same resource to implement data transmission, so as to support multi-user multiplexing and improve system capacity.

[0254] In addition, in the second resource, the number of time domain units of the X sub-resources for multi-user multiplexing is the same, and in the time domain, the X sub-resources are continuous except containing the third resource which is the unavailable time domain resource. In this way, the complexity of determining the X sub-resources can be reduced, and the processing complexity of the X times repeated transmission of the second uplink data can also be reduced.

[0255] As described in the foregoing, in the time domain, the X sub-resources are continuous except the third resource which includes the unavailable time domain resource. The third resource can not include the slot boundary, that is, the transmission of the X sub-resources can not be divided by the slot boundary.

[0256] In actual transmission, it is possible that the third resource does not contain, that is, the unavailable time domain resource (such as the downlink (D) symbol, invalid symbol, etc. described in the foregoing).

[0257] As an example, taking the scenario shown in FIG. 8a as an example. In FIG. 8a, on the time slots 1 to 4, a total of 4 times of repeated transmission is contained, and the duration of each repetition is 12 symbols, and the four times of repetition are as follows:

[0258] Repetition 1, occupying symbols 1 to 12 in time slot 1;

[0259] Repetition 2, occupying symbols 13 to 14 in time slot 1, and symbols 1 to 10 in time slot 2;

[0260] Repetition 3, occupying symbols 11 to 14 in time slot 2, and symbols 1 to 8 in time slot 3;

[0261] Repetition 4, occupying symbols 9 to 14 in time slot 3, and symbols 1 to 6 in time slot 4.

[0262] In the example shown in FIG. 8a, since there is no unavailable time domain resource, and without considering the splitting of the repeated transmission by the time slot boundary, it can be considered that different sub-resources in the X sub-resources are continuous in the time domain.

[0263] In actual transmission, there can be a third resource, i.e., containing an unavailable time domain resource (such as the downlink (D) symbol described above, invalid symbol, etc.).

[0264] As another example, taking the scenario shown in FIG. 8b as an example. In FIG. 8b, there are a total of 4 repeated transmissions on time slots 1 to 4, each repeated transmission has a duration of 12 symbols, and different repetitions will be separated by D symbols (i.e., symbol 13 in time slot 1 and symbol 12 in time slot 2), and the four repetitions are as follows:

[0265] Repetition 1, occupying symbols 1 to 12 in time slot 1;

[0266] Repetition 2, occupying symbol 14 in time slot 1 and symbols 1 to 11 in time slot 2;

[0267] Repetition 3, occupying symbols 13 to 14 in time slot 2 and symbols 1 to 10 in time slot 3;

[0268] Repetition 4, occupying symbols 11 to 14 in time slot 3 and symbols 1 to 8 in time slot 4.

[0269] In the example shown in FIG. 8b, since there is an unavailable time domain resource, and without considering the splitting of the repeated transmission by the time slot boundary, it can be considered that, in the X sub-resources, different sub-resources are continuous in the time domain, except for the unavailable time domain resource (such as the D symbol).

[0270] It should be noted that in the implementation process shown in FIG. 7, in the X sub-resources used to carry X repeated transmissions, one or more time domain units contained in any sub-resource can be continuous or discontinuous, which will be described below in conjunction with some implementation examples.

[0271] Implementation Example One, in the time domain, one or more time domain units contained in any sub-resource in the X sub-resources are continuous.

[0272] In implementation example one, in the second resource, the time domain units contained in any sub-resource in the X sub-resources for multi-user multiplexing can be continuous. In this way, the uplink data of each repeated transmission can be carried on continuous time units, which can ensure that the same repetition is transmitted through continuous time units, and can reduce the processing complexity of the uplink data carried by the same repetition.

[0273] For example, as shown in FIG. 8a and FIG. 8b, the one or more time domain units contained in any of the X sub-resources are continuous.

[0274] In a possible implementation of the implementation example one, the number of time domain units contained in any of the X sub-resources is Y, Y being a positive integer; and the third resource further includes available time domain resources, which contain a number of continuous time domain units less than Y in the time domain. Specifically, different sub-resources of the X sub-resources can be separated by the third resource, and the third resource can include available time domain resources with a number of time domain units less than Y in addition to the unavailable time domain resources, i.e., the X sub-resources for multi-user multiplexing can skip the unavailable time domain resources and the time domain resources with a small number of continuous time domain units. In this way, it can be ensured that the one or more time domain units contained in any of the X sub-resources are continuous.

[0275] In the example shown in FIG. 8b, the unavailable time domain resources are located just between different X sub-resources, and in actual applications, different X sub-resources can contain available time domain resources in addition to the unavailable time domain resources. For this purpose, the X sub-resources for multi-user multiplexing can skip the unavailable time domain resources and the time domain resources with a small number of continuous time domain units.

[0276] The implementation example one will be described below by way of example with reference to the example shown in FIG. 8c.

[0277] In FIG. 8c, there are 4 repeated transmissions in total on the time slots 1 to 4, each repetition lasts for 12 (Y=12) symbols, and different repetitions are separated by D symbols (i.e., symbol 1 in time slot 2 and symbol 4 in time slot 3), and the X sub-resources for multi-user multiplexing can skip the unavailable time domain resources and the time domain resources with a small number of continuous time domain units.

[0278] For example, in the example shown in FIG. 8c, there is an unavailable symbol (i.e., symbol 1 in time slot 2) after the time domain resources occupied by the repetition 1, and the last symbol occupied by the repetition 1 is located 2 (2 being less than Y) apart from the symbol 1 in time slot 2. The two apart symbols are symbol 13 and symbol 14 in time slot 1. In the implementation example one, although symbol 13 and symbol 14 in time slot 1 are available symbols, in order to ensure the time domain continuity within the same repeated transmission, the two symbols can be skipped.

[0279] For example, in the example shown in FIG. 8c, there are unavailable symbols (i.e. symbol 4 in slot 3) after the time domain resources occupied by repetition 2, and the last symbol occupied by repetition 2 is located between symbol 4 in slot 3 and the interval of 4 (4 is less than Y). The four interval symbols are symbol 14 in slot 2, symbols 1-3 in slot 3, respectively. In implementation example one, although the four interval symbols are available symbols, in order to guarantee the time domain continuity within the same repetition transmission, the two symbols can be skipped.

[0280] For this purpose, in the example shown in FIG. 8c, the four repetitions are as follows:

[0281] Repetition 1, occupying symbols 1-12 in slot 1;

[0282] Repetition 2, occupying symbols 2-13 in slot 2;

[0283] Repetition 3, occupying symbols 5-14 in slot 3, and symbols 1-2 in slot 3;

[0284] Repetition 4, occupying symbols 3-14 in slot 4.

[0285] In implementation example two, in the time domain, at least one of the X sub-resources contains at least two segments of time domain resources separated by unavailable time domain resources, and each segment of time domain resources contains one or more continuous time domain units.

[0286] In implementation example two, in the second resource, at least one of the X sub-resources for multi-user multiplexing contains at least two segments of time domain resources separated by unavailable time domain resources, and each segment of time domain resources contains one or more continuous time domain units. In this way, the uplink data of a repetition transmission can be carried by at least two segments of discontinuous time units, which can make the best use of available time domain resources to improve resource utilization.

[0287] Implementation example two will be described below with reference to the example shown in FIG. 9.

[0288] In the example shown in FIG. 9, the duration of each repetition is 12 (Y=12) symbols on slots 1-4, and it is assumed that the positions of the unavailable symbols are the same as in FIG. 8c, i.e. different repetitions are separated by D symbols (i.e. symbol 1 in slot 2, symbol 4 in slot 3), and at least one of the X sub-resources for multi-user multiplexing contains at least two segments of time domain resources separated by unavailable time domain resources, and each segment of time domain resources contains one or more continuous time domain units.

[0289] For example, in the example shown in FIG. 9, there is an unavailable symbol (i.e., symbol 1 in slot 2) after the time domain resource occupied by repetition 1, and the last symbol occupied by repetition 1 is located at an interval of 2 (2 is less than Y) from the symbol 1 in slot 2. The two interval symbols are symbol 13 and symbol 14 in slot 1, respectively. In the implementation example two, both symbol 13 and symbol 14 in slot 1 are available symbols, and in order to improve the number of resources occupied by the repeated transmission, the two symbols can be used as part of the resource of the next repeated transmission.

[0290] For example, in the example shown in FIG. 9, there is an unavailable symbol (i.e., symbol 1 in slot 2) after the time domain resource occupied by repetition 1, and the last symbol occupied by repetition 1 is located at an interval of 2 (2 is less than Y) from the symbol 1 in slot 2. The two interval symbols are symbol 13 and symbol 14 in slot 1, respectively. In the implementation example two, both symbol 13 and symbol 14 in slot 1 are available symbols, and in order to improve the number of resources occupied by the repeated transmission, the two symbols can be used as part of the resource of the next repeated transmission

[0291] Therefore, in the example shown in FIG. 9, the four repetitions are as follows:

[0292] Repetition 1, occupying symbols 1 to 12 in slot 1;

[0293] Repetition 2, including repetition 2-1 and repetition 2-2, occupying symbols 13 to 14 in slot 1, symbols 2 to 11 in slot 2;

[0294] Repetition 3, including repetition 3-1 and repetition 3-2, occupying symbols 12 to 14 in slot 2, symbols 1 to 3 in slot 3, symbols 5 to 10 in slot 3;

[0295] Repetition 4, occupying symbols 11 to 14 in slot 3, symbols 1 to 8 in slot 4.

[0296] As can be seen from the above implementation example one and implementation example two, by changing the resource mapping and redefining the rules of the repetition, the capacity can be maximized.
