[0001] The present application claims priority to the Chinese patent application No. 202410446646.6, filed on April 12, 2024, and entitled "Communication method and 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 apparatus. BACKGROUND

[0003] In a communication system, a base station can send control signaling to a terminal to configure the terminal. The terminal can send information to the base station according to the configuration in the control signaling. How to save the air interface resources occupied by the control signaling is a problem to be solved. SUMMARY

[0004] The present application provides a communication method and apparatus, which can save air interface resources.

[0005] To achieve the above object, the embodiments of the present application provide the following technical solutions:

[0006] In a first aspect, a communication method is provided, comprising: receiving first information, the first information indicating a first parameter corresponding to an orthogonal cover code (OCC) category; receiving a second parameter, the first parameter including the second parameter; and transmitting uplink information through an OCC category corresponding to the second parameter according to the second parameter and the first information.

[0007] Through the above scheme, the correspondence between the OCC category and the first parameter is received in advance. When actually scheduled for OCC encoding, only the first parameter corresponding to the OCC category needs to be received, and the OCC category does not need to be received again. According to the known correspondence between the OCC category and the first parameter, the OCC category is determined, and the data to be transmitted is OCC encoded using the category. Thus, the signaling overhead consumed by transmitting the OCC category is saved, and the air interface resources are saved. In addition, the data is transmitted in the manner of OCC, which can improve the number of terminals transmitting uplink data and improve the system capacity.

[0008] In combination with the first aspect, in a possible design, the receiving the second parameter includes: receiving the second parameter through DCI, configured grant type 1, or configured grant type 2.

[0022] In a possible design of the first aspect or the second aspect, the first parameter further includes a fifth parameter, the fifth parameter, the third parameter, and the fourth parameter are different, the fifth parameter corresponds to a third OCC category, and the third OCC category, the first OCC category, and the second OCC category are different.

[0023] In a possible design of the first aspect or the second aspect, the third parameter corresponding to the first OCC category is multiple, or the number of the fourth parameter corresponding to the second OCC category is multiple.

[0024] In a possible design of the first aspect or the second aspect, the number of one or more of the following parameters is multiple: the third parameter corresponding to the first OCC category, the fourth parameter corresponding to the second OCC category, or the fifth parameter corresponding to the third OCC category.

[0025] With the above solution, each OCC category can correspond to one or more first parameters, and thus the OCC category can be determined by any one of the multiple first parameters corresponding to the OCC category.

[0035] In a possible design of the first aspect or the second aspect, the first parameter is a value range. By indicating the value range, the correspondence between each value in the value range and the OCC category can be reduced, saving air interface resources.

[0067] Before introducing the technical solutions of the present application, the related technical terms involved in the present application are explained and described. It can be understood that these explanations and descriptions are to make the present application easier to be understood, and should not be regarded as limiting the scope of protection required by the present application.

[0068] 1. Repeat technology

[0069] The repeat technology refers to the terminal repeatedly sending uplink data (also referred to as uplink information). The base station can indicate the terminal to send the number of repetitions of the uplink data. The terminal can achieve uplink coverage enhancement through the repeat technology, but it will increase the time of the terminal transmitting the uplink data, and occupy more uplink resources and damage the system capacity.

[0070] 2. Non-terrestrial network (NTN)

[0071] NTN communication has the characteristics of large coverage area, flexible networking, etc., and can achieve seamless global network coverage. NTN can be used as a supplement to the current ground network, or as an independent communication system to provide global high-speed network access for users. Satellites in NTN operate at much higher altitudes than access network nodes in TN. Therefore, each satellite in NTN covers much larger land areas and serves more terminals than access network devices in TN, making it more difficult for each terminal to occupy uplink transmission resources in limited spectrum resources.

[0072] 3、OCC

[0073] The terminal can encode data according to the following three first parameters of the OCC: OCC scheme, OCC length and OCC index. The OCC scheme can be divided into inter-slot OCC, intra-symbol OCC and inter-symbol OCC. Inter-symbol OCC and intra-symbol OCC can be collectively referred to as symbol-level OCC, and inter-slot OCC can also be referred to as slot-level OCC. The OCC length includes 1, 2, 4, 12, etc. The OCC index corresponds to an OCC sequence, which is used to instruct the terminal to encode according to the sequence. The terminal can pre-store the correspondence between the OCC index and the OCC sequence. Alternatively, the terminal can receive indication information from the base station, which indicates the correspondence between the OCC index and the OCC sequence. For example, the OCC index is 1, and the corresponding OCC sequence is (1, 1). The OCC index is 2, and the corresponding OCC sequence is (1, -1).

[0074] The following takes the OCC encoding of terminal 1 and terminal 2 as an example to introduce the OCC encoding process. Assuming that the OCC scheme is inter-slot OCC, the OCC length is 2, the OCC sequence of terminal 1 is (1, 1), and the OCC sequence of terminal 2 is (1, -1). The data to be transmitted by terminal 1 is x, which is repeated twice. The data to be transmitted by terminal 2 is y, which is repeated twice. After terminal 1 encodes the repeated data x, it becomes (x, x). After terminal 2 encodes the repeated data y, it becomes (y, -y). The data received by the receiving end (such as the base station in the NTN satellite) is (x+y, x-y). After the receiving end adds the received data, it is divided by 2, i.e. (x+y+x-y) ÷ 2, and the data x transmitted by terminal 1 is obtained. After the receiving end subtracts the received data, it is divided by 2, i.e. (x+y-x+y) ÷ 2, and the data y transmitted by terminal 2 is obtained.

[0075] In order to improve the data transmission rate of the terminal, improve the throughput of the terminal, and increase the system capacity in limited frequency offset resources, the base station can instruct the terminal to use OCC to encode data, so as to realize the transmission of data of multiple terminals in the same PRB (physical resource block), or in other words, realize multiplexing of terminals in the same PRB, improve the throughput of the terminal, and increase the system capacity. However, when using OCC to transmit uplink information, the base station needs to instruct the terminal about the above-mentioned three parameters of OCC, which will cause a large signaling overhead.

[0076] In view of this, the embodiment of the present application provides a communication method. In the communication method provided by the embodiment of the present application, the terminal transmits uplink data in the manner of OCC, and when the base station instructs the terminal about the OCC category, the OCC category is bound with other parameters (such as the number of repetitions, the OCC length, etc.), the OCC category is indirectly instructed by instructing the other parameters, instead of directly instructing the OCC category, so as to reduce the instruction of the OCC category, thereby reducing the downlink scheduling signaling overhead.

[0077] The method provided by the present application can be used in various communication systems. For example, the communication system can be an LTE system, a 5G communication system, a WiFi system, a 3GPP related communication system, a communication system evolved after 5G (such as a 6G communication system), or a system integrating multiple systems, etc., without limitation. Among them, 5G can also be referred to as NR. In the following, the method provided by the present application will be described taking the communication system 1000 shown in FIG. 1 as an example. FIG. 1 is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the technical solutions provided by the present application.

[0078] FIG. 1 is an architecture schematic diagram of a communication system 1000 to which the embodiment of the present application is applied. As shown in FIG. 1, the communication system includes a RAN 100 and a core network 200. Optionally, the communication system 1000 can also include the Internet 300. Among them, the RAN 100 includes at least one RAN node (such as 110a and 110b in FIG. 1, collectively referred to as 110), and can also include at least one terminal (such as 120a-120j in FIG. 1, collectively referred to as 120). The RAN 100 can also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (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 integrating the logical functions of the core network device and the logical functions of the RAN node. The terminals and the terminals, and the RAN nodes and the RAN nodes can be connected to each other in a wired or wireless manner.

[0079] The RAN 100 can be an evolved universal terrestrial radio access (E-UTRA) system, a new radio (NR) system, and future wireless access systems defined in the 3rd generation partnership project (3GPP). The RAN 100 can also include two or more different wireless access systems described above. The RAN 100 can also be an open RAN (O-RAN).

[0080] The RAN node, also referred to as a radio access network device, RAN entity, or access node, is used to help terminals access the communication system through wireless means. In an application scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a 5th generation (5G) mobile communication system, a next generation NodeB in a 6th generation (6G) mobile communication system, or a base station in a future mobile communication system. The RAN node can be a macro base station (such as 110a in FIG. 1), a micro base station, or an indoor station (such as 110b in FIG. 1), and can also be a relay node or a donor node.

[0081] In another application scenario, wireless access can be achieved for a terminal through cooperation of multiple RAN nodes, and different RAN nodes respectively implement part of functions of a base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), or a radio unit (RU). Here, the CU implements functions of a radio resource control protocol and a packet data convergence protocol (PDCP) of a base station, and can also implement a function of a service data adaptation protocol (SDAP); the DU implements functions of a radio link control layer and a medium access control (MAC) layer of a base station, and can also implement part of a physical layer or all of a physical layer; and specific descriptions about the protocol layers can refer to related technical specifications of 3GPP. The RU can be used to implement functions of transceiving a radio frequency signal. The CU and the DU can be two independent RAN nodes, or can be integrated in a same RAN node, for example, integrated in a baseband unit (BBU). The RU can be included in a radio frequency device, for example, included in a remote radio unit (RRU) or an active antenna unit (AAU). The CU can be further divided into two types of RAN nodes, CU-control plane and CU-user plane.

[0082] In different systems, the RAN node can have different names. For example, in an O-RAN system, the CU can be referred to as an open CU (O-CU), the DU can be referred to as an open DU (O-DU), and the RU can be referred to as an open RU (O-RU). The RAN node in the embodiments of the present application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module. For example, the RAN node can be a server loaded with a corresponding software module. The embodiments of the present application do not limit specific technologies and specific device forms adopted by the RAN node. For ease of description, a base station is described as an example of the RAN node in the following.

[0083] A terminal is a device with wireless transceiving function, which can send signals to a base station or receive signals from a base station. A terminal can also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. A terminal can be widely applied in various scenarios, such as device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), internet of things (IOT), virtual reality, augmented reality, industrial control, automatic driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. A terminal can be a mobile phone, tablet computer, computer with wireless transceiving function, wearable device, vehicle, airplane, ship, robot, mechanical arm, smart home device, etc. Embodiments of the present application do not limit the specific technology and specific device form of the terminal.

[0084] A base station and a terminal can be fixed in position or movable. A base station and a terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water surface; can also be deployed on an airplane, balloon and artificial satellite. Embodiments of the present application do not limit the application scenarios of the base station and the terminal.

[0085] For example, embodiments of the present application can be applied in an NTN architecture, and a base station can be a base station in the NTN architecture. Referring to FIG. 2A, FIG. 2A shows another architecture schematic diagram of a communication system to which embodiments of the present application are applied. As shown in FIG. 2A, the communication system includes a core network, a ground station (also referred to as a gateway station), a satellite (satellite 1 and satellite 2), a base station (base station 1 and base station 2) and a terminal (terminal 1 and terminal 2).

[0086] The core network includes a user plane and a control plane. The user plane can process user-related data, and the control plane processes control-related data. The core network can include network functions such as a user plane function (UPF), an access and mobility management function (AMF), a location management unit (LMF), and a session management function (SMF), and perform user access control, mobility management, session management, user security authentication, billing, and other services. For example, the AMF can be responsible for user access management, security authentication, and mobility management. The LMF (not shown in the figure) can be responsible for managing and controlling positioning service requests for target terminals and processing positioning-related information. The UPF can be responsible for managing the transmission of user plane data, traffic statistics, and the like.

[0087] The satellite has all or part of the function of the base station, that is, the satellite can also be referred to as a base station. For example, satellite 1 can be referred to as base station 1, and satellite 2 can be referred to as base station 2. Satellite 1 and satellite 2 can be connected to each other through an Xn interface to realize signaling interaction and user data transmission between base stations. Satellite 1 can be connected to the ground station through an NG interface.

[0088] The ground station is connected to the core network through the NG interface. The ground station can forward signaling and service data between base stations and between base stations and the core network. For example, Non-Access Stratum (NAS) signaling and other signaling between core networks, and user service data.

[0089] Terminal 1 can communicate with base station 1 through an air interface and access the core network. Terminal 2 can communicate with base station 2 through an air interface and access the core network.

[0090] The air interface can refer to a wireless link between a terminal and a satellite.

[0091] The Xn interface can refer to an interface between base stations, which can realize signaling interaction such as handover.

[0092] The NG interface can refer to an interface between a base station and a core network, which can realize NAS signaling and other signaling between core networks, and user service data.

[0093] Referring to FIG. 2B, FIG. 2B shows another architecture schematic diagram of a communication system to which embodiments of the present application are applied. As shown in FIG. 2B, the communication system includes a core network, a ground station, a satellite 3, a base station 3, a terminal 3, and a data network.

[0094] The related introduction of the core network can refer to the communication system shown in FIG. 2A. The ground station can forward data between the satellite and the base station.

[0095] The base station 3 can be arranged on the ground and connected with the ground station. The ground station is connected with the satellite 3. The terminal 3 can be connected with the satellite 3 through the air interface, so as to access the communication network.

[0096] Similar to the communication system shown in FIG. 2A, in the communication system shown in FIG. 2B, the satellite 3 can also be connected with other satellites to realize data transmission between satellites.

[0097] In some examples, the satellite 3 is deployed with all or part of the functions of the base station, and signaling interaction and user data transmission can be realized between satellites. In other examples, the satellite 3 is not deployed with the functions of the base station, and the satellite can perform transparent forwarding of data to the terminal or the ground station. The satellite and the satellite can also perform transparent forwarding.

[0098] The above FIG. 2A and FIG. 2B take the communication architecture of the 5G system as an example to introduce the NTN network. In the 4G system, the Xn interface can be referred to as the X2 interface, and the NG interface can be referred to as the S1 interface. In other systems, such as the 6G system, the above interfaces can also use other names.

[0099] The roles of the base station and the terminal can be relative, for example, the helicopter or the unmanned aerial vehicle 120i in FIG. 1 can be configured as a mobile base station, and for those terminals 120j that access the wireless access network 100 through 120i, the terminal 120i is a base station; but for the base station 110a, 120i is a terminal, that is, 110a and 120i communicate through a wireless air interface protocol. Of course, 110a and 120i can also communicate through the interface protocol between the base stations and the base stations, at this time, relative to 110a, 120i is also a base station. Therefore, the base station and the terminal can be collectively referred to as a communication device, 110a and 110b in FIG. 1 can be referred to as a communication device with a base station function, and 120a-120j in FIG. 1 can be referred to as a communication device with a terminal function.

[0100] The base station and the terminal, the base station and the base station, and the terminal and the terminal can communicate through the licensed spectrum, or through the unlicensed spectrum, or through the licensed spectrum and the unlicensed spectrum at the same time; can communicate through the spectrum below 6 gigahertz (GHz), or through the spectrum above 6 GHz, or through the spectrum below 6 GHz and the spectrum above 6 GHz at the same time. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0101] In the embodiments of the present application, the functions of the base station can also be performed by a module (such as a chip) in the base station, or by a control subsystem containing the functions of the base station. The control subsystem containing the functions of the base station herein can be a control center in the above-mentioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. The functions of the terminal can also be performed by a module (such as a chip or a modem) in the terminal, or by a device containing the functions of the terminal.

[0102] In the present application, the base station sends a downlink signal or downlink information to the terminal, and the downlink information is carried on a downlink channel; the terminal sends an uplink signal or uplink information to the base station, and the uplink information is carried on an uplink channel. In order to communicate with the base station, the terminal needs to establish a wireless connection with a cell controlled by the base station. The cell with which the terminal establishes a wireless connection is called the service cell of the terminal. When the terminal communicates with the service cell, it will also be interfered by signals from neighboring cells.

[0103] It can be understood that, in the embodiments of the present application, PDSCH, PDCCH and PUSCH are only examples of a downlink data channel, a downlink control channel and an uplink data channel, respectively. In different systems and different scenarios, data channels and control channels can have different names, and the embodiments of the present application do not limit this.

[0104] The following describes a communication method provided by the embodiments of the present application, taking the communication between a terminal and a base station as an example. Referring to FIG. 3, FIG. 3 is a flowchart of a communication method provided by the embodiments of the present application, which can be applied to the interaction between a terminal and a base station in any one of the communication systems shown in FIGS. 1 to 2B. The method can include the following steps:

[0105] S301, the base station sends first information. Correspondingly, the terminal receives the first information.

[0106] The first information indicates a first parameter corresponding to an OCC category. In a possible implementation, the first information indicates an OCC category and a first parameter corresponding to the OCC category.

[0107] For example, the base station can pre-store the first parameter corresponding to the OCC category. For another example, the base station can receive indication information of a network element in a core network, the indication information indicating the first parameter corresponding to the OCC category.

[0108] In a possible implementation, the first parameter includes a parameter of one or more of the following dimensions: number of repetitions of the uplink information, OCC length, number of frequency domain resources of the uplink information, number of bits of the transport block, coding and modulation mode, repetition mode of the uplink information, mapping mode of the uplink information, number of symbols of the starting symbol of the uplink information, or length of the starting symbol of the uplink information. Here, S301 is first introduced by taking the number of repetitions of the uplink information and the OCC length and the corresponding first parameter as an example. The remaining dimensions and the corresponding first parameter will be described in detail in the following embodiments.

[0109] In some embodiments, the uplink information can refer to PUSCH. For example, the number of frequency domain resources of the uplink information refers to the number of frequency domain resources of the PUSCH. The repetition mode of the uplink information refers to the repetition mode of the PUSCH. The mapping mode of the uplink information refers to the mapping mode of the PUSCH. The number of symbols of the starting symbol of the uplink information refers to the number of symbols of the starting symbol of the PUSCH. The length of the starting symbol of the uplink information refers to the length of the starting symbol of the PUSCH.

[0110] The number of repetitions of the uplink information (number of repetitions or aggregation factor) refers to the number of times of repeatedly sending information in the repetition technology. The value of the number of repetitions can refer to the examples below.

[0111] The length of the OCC refers to the length of the OCC corresponding to the OCC category. As described above, the terminal encodes the data to be sent according to the OCC category, the length corresponding to the OCC category, and the sequence corresponding to the OCC category.

[0112] The first information can indicate the first parameter corresponding to the OCC category in various ways. For example, the first information indicates the correspondence in the form of a key-value pair, such as the first information including {first parameter: OCC category}. Alternatively, the first information can include a first parameter set and an OCC category set, where the i-th first parameter in the first parameter set corresponds to the j-th OCC category in the OCC category set.

[0113] In some embodiments, one OCC category corresponds to one or more first parameters. Alternatively, the number of third parameters can be one or more. Similarly, the number of fourth parameters and fifth parameters can also be one or more.

[0114] In some examples, the first parameter includes a third parameter and a fourth parameter, and the third parameter and the fourth parameter are different. The third parameter corresponds to a first OCC category, the fourth parameter corresponds to a second OCC category, and the first OCC category and the second OCC category are different.

[0115] For example, the first parameters corresponding to each OCC category belong to the same dimension. The first parameters indicated by the first information include the repetition times of the uplink information corresponding to the plurality of OCC categories. Referring to Table 1, N represents the repetition times, N1 represents 1 repetition, N2 represents 2 repetitions, and so on. The first OCC category is symbol-level OCC, and the symbol-level OCC can correspond to 4 third parameters, which are N1, N2, N3, and N4 respectively. The second OCC category is inter-slot OCC, and the inter-slot OCC can correspond to 4 fourth parameters, which are N7, N8, N12, and N16 respectively.

[0116] Table 1

[0117] It can be understood that the repetition times of the uplink information shown in Table 1 are only examples, and in other embodiments, the repetition times of the uplink information can also be other times, such as 9 times, 32 times, etc., and 9 times and 32 times can also correspond to OCC categories.

[0118] It can be understood that the correspondence between the repetition times of the uplink information and the OCC categories shown in Table 1 is only an example. In other embodiments, as shown in Table 2, the symbol-level OCC can correspond to repetition times of the uplink information of 7, 8, 12, and 16, etc., and the inter-slot OCC can correspond to repetition times of the uplink information of 1, 2, 3, and 4, etc.

[0119] Table 2

[0120] In some embodiments, the base station can indicate to the terminal in advance that the symbol-level OCC is intra-symbol OCC. Alternatively, the base station can indicate to the terminal in advance that the symbol-level OCC is inter-symbol OCC.

[0121] For another example, the first parameters corresponding to each OCC category belong to multiple dimensions. For example, referring to Table 3, the third parameters can be any one of the repetition times 1 to 4 of the uplink information. The fourth parameters can be any one of the OCC lengths 4 to 7, the first OCC category is symbol-level OCC, and the second OCC category is inter-slot OCC.

[0122] Table 3

[0123] In other examples, the first parameters further include a fifth parameter, the fifth parameter, the third parameter, and the fourth parameter are different from each other, the fifth parameter corresponds to a third OCC category, the third OCC category, the first OCC category, and the second OCC category are different from each other.

[0124] For example, referring to Table 4, the intra-symbol OCC can correspond to the repetition number of 1, 2, etc. of the uplink information, the inter-symbol OCC can correspond to the repetition number of 3, 4, 7, etc. of the uplink information, and the inter-slot OCC can correspond to the repetition number of 8, 12, 16, 32, etc. of the uplink information.

[0125] Table 4

[0126] For example, referring to Table 5, the third parameter can include the OCC length (occ-length) less than 2 and the repetition number of the uplink information less than 2, and the first OCC category is the inter-symbol OCC. The fourth parameter can include the OCC length greater than or equal to 2 and the repetition number of the uplink information less than 2, and the second OCC category is the intra-symbol OCC. The fifth parameter can include the OCC length less than 2 and the repetition number of the uplink information greater than 2, and the third OCC category is the inter-slot OCC. In some embodiments, the first parameter corresponds to the inter-slot OCC when the value of the first parameter is not in the above cases. For example, the fifth parameter can also include the OCC length less than 2 and the repetition number of the uplink information equal to 2. For example, the fifth parameter can also include the OCC length greater than or equal to 2 and the repetition number of the uplink information greater than or equal to 2. For example, the present example can be represented by the following code:

[0127] Table 5

[0128] In some embodiments, the third parameter corresponding to the first OCC category includes the third parameter of the first dimension and the third parameter of the second dimension. The fourth parameter corresponding to the second OCC category includes the fourth parameter of the first dimension and the fourth parameter of the second dimension.

[0129] For example, referring to Table 6, the third parameter can be the repetition number of the uplink information 1 or 2, or the OCC length 2 or 3. The fourth parameter can be the repetition number of the uplink information 7 or 8, or the OCC length 6 or 7, the first OCC category is the symbol-level OCC, and the second OCC category is the inter-slot OCC.

[0130] Table 6

[0131] For example, when the repetition number of the uplink information is less than twice and the OCC length is less than or equal to 2, the symbol-level OCC is corresponded. For example, when the repetition number of the uplink information is greater than 4 and the OCC length is greater than 4, the symbol-level OCC is corresponded.

[0132] In some embodiments, the fifth parameter corresponding to the third OCC category includes a fifth parameter in the first dimension and a fifth parameter in the second dimension. For example, referring to Table 5, the third OCC category is inter-slot OCC, the first dimension is the repetition number of the uplink information, and the second dimension is the OCC length.

[0133] In some embodiments, each first parameter corresponds to one OCC category. For example, referring to the examples shown in Table 1, Table 3, and the like.

[0134] In some embodiments, part of the first parameters correspond to multiple OCC categories. For example, referring to the examples shown by the code, when the OCC length is less than 2, in the case of different repetition numbers of uplink information, it corresponds to inter-slot OCC or inter-symbol OCC. When the repetition number of uplink information is equal to two, it corresponds to inter-slot OCC. In this example, the OCC category can be determined by multiple dimensions of the first parameter.

[0135] In some embodiments, the first parameter is a numerical value, and the OCC categories corresponding to the two first parameters adjacent to the first parameter are different. The two first parameters adjacent to the first parameter refer to the first parameter greater than the first parameter and the first parameter less than the first parameter. For example, referring to Table 1, when the repetition number of uplink information is 4, the two first parameters adjacent to the first parameter are 3 and 7. When the repetition number of uplink information is 7, the two first parameters adjacent to the first parameter are 4 and 8.

[0136] In some embodiments, the first information indicates that the first parameter corresponding to the OCC category is at the separation. For example, referring to Table 7, the first information indicates that when the repetition number of uplink information is less than or equal to 4, it corresponds to symbol-level OCC.

[0137] Table 7

[0138] In other embodiments, the first parameter is a numerical range. For example, the dimension of the first parameter is the repetition number of uplink information. The first parameter corresponding to the symbol-level OCC is 1 to 4. The first parameter corresponding to the inter-slot OCC is 7 to 32. The first information can indicate the first parameter in the form of a set. For example, the first information indicates {[1, 4], symbol-level OCC}. By indicating the numerical range, the correspondence between each numerical value in the numerical range and the OCC category can be reduced, and the air interface resources can be saved.

[0139] S302, the base station sends the second parameter. Correspondingly, the terminal receives the second parameter.

[0140] The first parameter includes the second parameter. Alternatively, the second parameter includes one or more parameters in the first parameter. Alternatively, the second parameter belongs to the first parameter. For example, as shown in Table 1, the first parameter indicated by the first information includes the number of repetitions of uplink information corresponding to each OCC category. The second parameter can be any one of N1, N2, N3, N4, N7, N8, N12, or N16. For another example, the number of second parameters can be multiple. Referring to Table 5, the second parameter 1 can be the number of repetitions of uplink information, and the second parameter 2 can be the OCC length. For another example, the second parameter is the OCC length, and the base station indicates the OCC length to the terminal.

[0141] In some embodiments, the base station sends the second parameter through DCI. The terminal receives the second parameter through DCI. Alternatively, the base station sends the second parameter through configured grant type 1 (CG type 1). The terminal receives the second parameter through CG type 1. Alternatively, the base station sends the second parameter through configured grant type 2 (CG type 2). The terminal receives the second parameter through CG type 2.

[0142] For example, the uplink information is PUSCH. The second parameter is a parameter of the following dimensions: the number of repetitions of uplink information, the number of frequency domain resources of PUSCH, the number of bits of a transport block, a coding and modulation mode, a repetition mode of PUSCH, a mapping mode of PUSCH, the number of symbols of a starting symbol of PUSCH, or the length of the starting symbol of PUSCH. The base station schedules the terminal to send PUSCH using OCC through DCI, and can indicate one or more of the second parameter, the OCC length, and the OCC sequence in the DCI. In one implementation of the embodiments of the present application, the base station can directly indicate the OCC sequence. In another implementation of the embodiments of the present application, the base station can indicate the OCC sequence by indicating an OCC index. For example, the terminal stores a correspondence between the OCC index and the OCC sequence, and the terminal can determine the OCC sequence through the OCC index.

[0143] For another example, the second parameter is the first parameter of the OCC length. The base station schedules the terminal to send PUSCH using OCC through DCI, and can indicate one or more of the second parameter and the OCC sequence in the DCI.

[0144] For another example, the second parameter is a parameter of a dimension (e.g., the above-mentioned dimension or the below-mentioned time dimension) other than the OCC length. The base station schedules the terminal to transmit the PUSCH using the OCC through the CG type 1, and can indicate one or more of the second parameter, the OCC length and the OCC sequence in the RRC signaling (e.g., configuredGrantConfig / rrc-configureduplinkgrant signaling). For another example, the second parameter is a parameter of the OCC length. The base station schedules the terminal to transmit the PUSCH using the OCC through the CG type 1, and can indicate one or more of the second parameter and the OCC sequence in the RRC signaling.

[0145] For another example, the second parameter is a parameter of a dimension (e.g., the above-mentioned dimension or the below-mentioned time dimension) other than the OCC length. The base station schedules the terminal to transmit the PUSCH using the OCC through the CG type 2, and can indicate one or more of the second parameter, the OCC length and the OCC sequence in the RRC signaling (e.g., configuredGrantConfig / rrc-configureduplinkgrant) or in the DCI. For another example, the second parameter is a parameter of the OCC length. The base station schedules the terminal to transmit the PUSCH using the OCC through the CG type 2, and can indicate one or more of the second parameter and the OCC sequence in the RRC signaling or in the DCI.

[0146] In some other embodiments, the second parameter can also be indicated by other forms of RRC signaling, such as MAC-CE.

[0147] S303, the terminal transmits the uplink information using the OCC corresponding to the second parameter according to the second parameter and the first information. Correspondingly, the base station receives the uplink information using the OCC corresponding to the second parameter.

[0148] For example, the first information indicates the first parameter corresponding to the OCC category shown in Table 1. The dimension of the first parameter sent by the base station is the repetition number of the uplink information, and the second parameter is N2. The terminal receives N2, and determines the OCC category to be symbol-level OCC according to the correspondence between the OCC category and the first parameter shown in Table 1. Thus, the terminal can use symbol-level OCC to encode the uplink information to be transmitted according to the known OCC length and OCC sequence. Thus, the base station can decode the received information using the symbol-level OCC corresponding to the second parameter to obtain the uplink information.

[0149] If the second parameter is N7, the terminal can determine, according to the correspondence between the OCC category and the first parameter shown in Table 1, that the OCC category is inter-slot OCC. Thus, the terminal can perform OCC encoding on the to-be-sent uplink information by using inter-slot OCC. Thus, the base station can perform OCC decoding on the received information by using the inter-slot OCC corresponding to the second parameter to obtain the uplink information.

[0150] For another example, the first parameter indicated by the first information is a parameter corresponding to the OCC category at a separation. The terminal can be pre-configured to perform symbol-level OCC or inter-slot OCC. The terminal receives the first information, which indicates that the repetition number of the uplink information is 4 times corresponding to symbol-level OCC. The terminal can determine, according to the correspondence, that symbol-level OCC is used when the repetition number of the uplink information is less than 4 times, and inter-slot OCC is used when the repetition number of the uplink information is greater than 4 times. Thus, when the terminal receives the second parameter indicating that the repetition number of the uplink information is 8 times, it is determined that 8 is greater than 4. It is determined that inter-slot OCC is used as the OCC category to encode the information to be sent by the terminal. Thus, the base station can perform OCC decoding on the received information by using the OCC category corresponding to the second parameter to obtain the uplink information.

[0151] Through the above scheme, the base station sends the correspondence between the OCC category and the first parameter to the terminal in advance. When actually scheduling the terminal to perform OCC encoding, only the first parameter corresponding to the OCC category needs to be indicated, and the OCC category does not need to be indicated again. The terminal can determine the OCC category according to the known correspondence between the OCC category and the first parameter, and perform OCC encoding on the to-be-sent data by using the category. Thus, the signaling overhead consumed by indicating the OCC category is saved, and the air interface resources are saved. In addition, the data is transmitted in the OCC manner, which can improve the number of terminals sending uplink data and improve the system capacity.

[0152] The overall flow of the communication method provided by the present application is described above, and the above dimensions are described in detail below.

[0153] The uplink information is taken as an example of PUSCH. The number of frequency domain resources of PUSCH can indicate the number of frequency domain resources of PUSCH allocated by the base station to the terminal. For example, the number of frequency domain resources of PUSCH can be indicated by a bandwidth part identifier (BWP ID). For example, when the value of BWP ID is #0, it corresponds to inter-symbol OCC, and when the value of BWP ID is #1, it corresponds to intra-symbol OCC.

[0154] The number of bits of the transport block can refer to the size of the transport block indicated by the base station to the terminal when transmitting data next time. For example, when the value of TBS is less than or equal to 208 bits, it corresponds to inter-symbol OCC, and when the value of TBS is greater than 208, it corresponds to intra-symbol OCC.

[0155] The encoding and modulation mode can refer to the encoding and modulation mode of the terminal to the PUSCH. For example, the encoding and modulation mode of the terminal to the PUSCH using OCC. For example, when the encoding and modulation mode is quadrature phase shift keying (QPSK), it corresponds to inter-symbol OCC, and when the encoding and modulation mode is differential phase shift keying (DPSK), it corresponds to intra-symbol OCC.

[0156] The repetition mode of the PUSCH can include repetition mode A and repetition mode B. The specific implementation of repetition mode A and repetition mode B can refer to the 3GPP protocol. For example, the repetition mode A of the PUSCH corresponds to the slot-level OCC, and the repetition mode B of the PUSCH corresponds to the symbol-level OCC.

[0157] The mapping mode of the PUSCH can include mapping mode A and mapping mode B. The specific implementation of mapping mode A and mapping mode B can refer to the 3GPP protocol. For example, the mapping mode A of the PUSCH corresponds to the slot-level OCC, and the mapping mode B of the PUSCH corresponds to the symbol-level OCC.

[0158] For example, the number of symbols of the starting symbol of the PUSCH is S in the starting length indicator value (SLIV). Wherein, the SLIV includes S and L, S represents the number of symbols, and L represents the length. For example, when the value of S in the SLIV is 66, it corresponds to inter-symbol OCC, and when the value of S in the SLIV is 26, it corresponds to intra-symbol OCC.

[0159] For example, the length of the starting symbol of the PUSCH is L in the SLIV. For example, when the value of L in the SLIV is 14, it corresponds to inter-symbol OCC, and when the value of L in the SLIV is 6, it corresponds to intra-symbol OCC.

[0160] In some embodiments, the base station can determine the OCC category used according to the measurement report sent by the terminal to the base station. Next, taking the first information indicating the parameter of the repetition number of the uplink information corresponding to the OCC category under the NTN architecture as an example, the method of the embodiments of the application is introduced. Referring to FIG. 4, the communication method of the embodiments of the application can include the following steps.

[0161] S401, the terminal reports a measurement report. Correspondingly, the base station receives the measurement report.

[0162] The measurement report can refer to a channel condition of the terminal. For example, the measurement includes one or more of a reference signal received power (RSRP), a channel state information (CSI), and a service quality indicator (SQI).

[0163] For example, referring to FIG. 2A, the terminal 1 can send the measurement report to the base station 1 through the air interface. For another example, referring to FIG. 2B, the terminal 3 can send the measurement report to the satellite 3 through the air interface, and the satellite 3 sends the measurement report to the base station through the ground station.

[0164] S402, the base station sends first information. Correspondingly, the terminal receives the first information.

[0165] The first information indicates a repetition number of uplink information corresponding to an OCC category. For example, the base station can pre-store the repetition number of uplink information corresponding to the OCC category, and thus send the repetition number of uplink information corresponding to the OCC category in the first information. For another example, the base station can determine the repetition number of uplink information corresponding to the OCC category according to the RSRP of multiple terminals simultaneously scheduled by the base station. When the RSRP of multiple terminals simultaneously scheduled by the base station is greater than a first threshold, a first repetition number of uplink information corresponding to OCC category 1 and a second repetition number of uplink information corresponding to OCC category 2. When the RSRP of multiple terminals simultaneously scheduled by the base station is less than or equal to the first threshold, a third repetition number of uplink information corresponding to OCC category 1 and a fourth repetition number of uplink information corresponding to OCC category 2. For example, the first threshold is -10 dBm, OCC category 1 is intra-slot OCC, OCC category 2 is inter-symbol OCC, the first repetition number of uplink information is 4, the second repetition number of uplink information is 6, the third repetition number of uplink information is 7, and the fourth repetition number of uplink information is 8.

[0166] For example, referring to FIG. 2A, the base station 1 can send the first information to the terminal through the air interface. For another example, referring to FIG. 2B, the base station 3 can send the first information to the satellite 3 through the ground station, and the satellite 3 forwards the first information to the terminal 3. Thus, the terminal 3 receives the first information.

[0167] S403, the base station indicates a second parameter. Correspondingly, the terminal receives the second parameter.

[0168] In some embodiments, the base station can determine the OCC category used by the terminal through the measurement report of the terminal. Thus, the second parameter is determined as the repetition number of the uplink information corresponding to the OCC category.

[0169] S404, the terminal transmits the uplink information through the OCC category corresponding to the second parameter according to the second parameter and the first information. Correspondingly, the base station receives the uplink information through the OCC category corresponding to the second parameter.

[0170] The examples of S403 and S404 can refer to the related examples of S303. Thus, according to the above steps, the base station can indicate the OCC category to the terminal with less overhead, so that the terminal can process the information in the manner of OCC. Thus, in the NTN scenario, the number of terminals that can transmit uplink data in a large number of terminals within the coverage of each satellite can be increased, and the throughput of the terminal can be improved.

[0171] In some embodiments, the base station can determine the OCC category used by the terminal according to the measurement report sent by the terminal to the base station. Next, taking the parameter that the first information indicates the OCC length corresponding to the OCC category as an example, the method of the embodiments of the present application in the NTN architecture is introduced. Referring to FIG. 5, the communication method of the embodiments of the present application can include the following steps.

[0172] S501, the terminal reports a measurement report. Correspondingly, the base station receives the measurement report.

[0173] The related description of S501 can refer to S401, which will not be repeated here.

[0174] S502, the base station sends the first information. Correspondingly, the terminal receives the first information.

[0175] The first information indicates the OCC length corresponding to the OCC category.

[0176] For example, the base station can pre-store the OCC length corresponding to the OCC category, so as to indicate the OCC length corresponding to the OCC category in the first information.

[0177] S503, the base station indicates the second parameter. Correspondingly, the terminal receives the second parameter.

[0178] In some embodiments, the base station can determine the OCC category used by the terminal through the measurement report of the terminal. Thus, the second parameter is determined as the OCC length corresponding to the OCC category.

[0179] S504, the terminal transmits the uplink information through the OCC category corresponding to the second parameter according to the second parameter and the first information. Correspondingly, the base station receives the uplink information through the OCC category corresponding to the second parameter.

[0180] For example, the first parameter corresponding to the OCC category shown in Table 8 is indicated by the first information. The base station sends the first parameter with a dimension of OCC length, and the second parameter is an OCC length of 2. The terminal receives the OCC length of 2, and determines the OCC category to be a slot-level OCC according to the correspondence between the OCC category and the first parameter shown in Table 8. Thus, the terminal can use the slot-level OCC to encode the uplink information to be sent. Thus, the base station can receive the uplink information through the slot-level OCC corresponding to the second parameter according to the second parameter and the first information.

[0181] If the second parameter is 4, the terminal can obtain 4 greater than 2 according to the correspondence between the OCC category and the first parameter shown in Table 8, and determine the OCC category to be a symbol-level OCC. Thus, the terminal can use the symbol-level OCC to encode the uplink information to be sent. Thus, the base station can receive the uplink information through the symbol-level OCC corresponding to the second parameter according to the second parameter and the first information.

[0182] Table 8

[0183] For example, the terminal and the base station can agree in advance that the symbol-level OCC refers to intra-symbol OCC. Alternatively, it is agreed in advance that the symbol-level OCC refers to inter-symbol OCC. Thus, when the terminal receives the first information, it can determine whether the symbol-level OCC refers to intra-symbol OCC or inter-symbol OCC according to the agreement in advance.

[0184] According to the above scheme, the base station indicates the OCC category to the terminal with less overhead, so that the terminal can process the information in the OCC manner. Thus, in the NTN scenario, the number of terminals that can send uplink data in a large number of terminals within the coverage of each satellite can be increased, and the throughput of the terminal can be improved.

[0185] The above examples are based on the first information including the number of repetitions of the uplink information and the OCC length. It can be understood that when one or more of the above dimensions (the number of repetitions of the uplink information, the length of the OCC, the number of frequency domain resources of the uplink information, the number of bits of the transport block, the coding and modulation manner, the repetition manner of the uplink information, the mapping manner of the uplink information, the number of symbols of the starting symbol of the uplink information, or the length of the starting symbol of the uplink information) are included in the first information, the terminal and the base station can execute the process according to the embodiments shown in FIGS. 4 and 5.

[0186] The above describes that the first information can include a first parameter of multiple dimensions. In some other embodiments, the first information can also include a first parameter of other categories. For example, a time period, a distance between the terminal and a reference point, an angle (such as an elevation angle or a depression angle) between the terminal and the satellite, a remaining coverage time of a serving cell of the terminal covering the terminal, and the like.

[0187] For example, the first information can indicate a distance between the terminal and a reference point greater than a first threshold corresponding to a time slot level OCC, and indicate a distance between the terminal and the reference point less than or equal to a first threshold corresponding to a symbol level OCC. For example, the first threshold can be 500 kilometers. The reference point can be a coordinate point agreed by the base station and the terminal. For another example, the first information can indicate a distance between the terminal and a reference point less than a first threshold corresponding to an intra-symbol OCC, indicate a distance between the terminal and the reference point greater than the first threshold and less than a second threshold corresponding to an inter-symbol OCC, and indicate a distance between the terminal and the reference point greater than the second threshold corresponding to an inter-time slot OCC. The second threshold is greater than the first threshold. For example, the first threshold can be 500 kilometers, and the second threshold can be 700 kilometers.

[0188] For another example, the first information can indicate an elevation angle between the terminal and a satellite less than a third threshold corresponding to a time slot level OCC, and indicate an elevation angle between the terminal and the satellite greater than a third threshold corresponding to a symbol level OCC. For example, the third threshold can be 30 degrees.

[0189] For another example, the first information can indicate a remaining coverage time of a serving cell of the terminal covering the terminal less than a fourth threshold corresponding to a symbol level OCC, and indicate a remaining coverage time of the serving cell of the terminal covering the terminal greater than or equal to a fourth threshold corresponding to a time slot level OCC. For example, the fourth threshold can be 10 minutes.

[0190] Hereinafter, the method of the embodiments of the present application is introduced by taking the parameter of the time corresponding to the OCC category indicated by the first information as an example. Referring to FIG. 6, the communication method of the embodiments of the present application can include the following steps.

[0191] S601, the terminal reports a measurement report. Correspondingly, the base station receives the measurement report.

[0192] The related description of S601 can refer to S401, which is not described here again.

[0193] S602, the base station sends first information. Correspondingly, the terminal receives the first information.

[0194] The first information indicates a time period corresponding to an OCC category. The base station can determine the OCC category of the terminal according to the measurement report. The base station can determine the time period corresponding to the OCC category. Thus, the time period corresponding to the OCC category is sent in the first information. For example, the base station can determine the time period corresponding to the OCC category through the running track of the satellite connected with the terminal. For example, referring to FIG. 2A, the terminal 1 is connected with the satellite 1, in the time period [t1, t2], the terminal 1 is far away from the satellite 1, the signal quality is poor, and the inter-time slot OCC is used. In the time period [t3, t4], the terminal 1 is close to the satellite 1, the signal quality is good, and the symbol level OCC is used.

[0195] S603, the base station indicates the second parameter. Correspondingly, the terminal receives the second parameter.

[0196] S604, the terminal transmits uplink information according to the second parameter and the first information through the OCC category corresponding to the second parameter. Correspondingly, the base station receives the uplink information through the OCC category corresponding to the second parameter.

[0197] For example, the second parameter is t5. The terminal receives t5, and determines that t5 belongs to the time period [t1, t2] according to the correspondence between the time period and the OCC category, so as to determine that the OCC category is inter-slot OCC. Therefore, the terminal can use inter-slot OCC to encode the uplink information to be transmitted. Therefore, the base station can receive the uplink information through the inter-slot OCC corresponding to the second parameter according to the second parameter and the first information.

[0198] In the above example, the terminal transmits uplink information to the base station, which can be PUSCH, and the terminal encodes the PUSCH through OCC. Therefore, the multiplexing of multiple terminals on the uplink channel is realized.

[0199] It can be understood that in the above example, the example shown in FIGS. 4 to 6. The terminal transmits the first information, the second parameter and the like to the base station, and the terminal can establish an RRC connection with the base station, so as to realize communication with the base station.

[0200] The above embodiments introduce that the base station indicates the first information, the first information indicates the first parameter corresponding to the OCC category, so as to no longer need to indicate the OCC category, thereby reducing the air interface resources consumed by indicating the OCC category. In some other embodiments, the base station can transmit second information, the second information can indicate the sixth parameter corresponding to the OCC length, so that the base station can no longer indicate the OCC length, thereby reducing the air interface resources consumed by indicating the OCC length. Referring to FIG. 7, the embodiments of the present application include the following steps.

[0201] S701, the terminal reports a measurement report. Correspondingly, the base station receives the measurement report.

[0202] The related description of S701 can refer to S301, which will not be repeated here. It should be noted that S701 is an optional step, and in some embodiments, the terminal can not perform S701.

[0203] S702, the base station transmits second information. Correspondingly, the terminal receives the second information.

[0204] The second information indicates the sixth parameter corresponding to the OCC length.

[0205] Exemplarily, the sixth parameter includes one or more of the following dimensional parameters: the number of repetitions of the uplink information, the number of frequency domain resources of the uplink information, the number of bits of the transport block, the coding and modulation mode, the repetition mode of the uplink information, the mapping mode of the uplink information, the number of symbols of the starting symbol of the uplink information, or the length of the starting symbol of the uplink information.

[0206] Similar to the first parameter, the sixth parameter can also include parameters of multiple dimensions. Each OCC length can correspond to one or more dimensional parameters. The correspondence between the OCC length and the one or more dimensional parameters can refer to the correspondence between the OCC category and the one or more dimensions described above, and will not be described here again.

[0207] In some embodiments, the sixth parameter can be the same parameter as the first parameter. That is, the sixth parameter corresponds to both the OCC category and the OCC length. Exemplarily, the sixth parameter includes one or more of the following dimensional parameters: the number of repetitions of the uplink information, the number of frequency domain resources of the uplink information, the number of bits of the transport block, the coding and modulation mode, the repetition mode of the uplink information, the mapping mode of the uplink information, the number of symbols of the starting symbol of the uplink information, or the length of the starting symbol of the uplink information.

[0208] Taking the number of repetitions of the uplink information as the sixth parameter, referring to Table 9, N1 and N2 correspond to the OCC length of 2 and the OCC category of intra-symbol OCC. N3 corresponds to the OCC length of 2 and the OCC category of inter-symbol OCC. And so on.

[0209] Table 9

[0210] In some embodiments, the first information and the second information can be the same information. That is, the first information indicates both the first parameter corresponding to the OCC length and the sixth parameter corresponding to the OCC category. Exemplarily, the first information can indicate the correspondence relationship as shown in Table 9.

[0211] S703, the base station indicates the seventh parameter. Correspondingly, the terminal receives the seventh parameter.

[0212] The sixth parameter includes the seventh parameter. Or, the seventh parameter includes one or more parameters in the sixth parameter. Or, the seventh parameter belongs to the sixth parameter. Exemplarily, referring to Table 9, the seventh parameter can be N1.

[0213] S704, the terminal transmits the uplink information through the OCC length corresponding to the seventh parameter according to the seventh parameter and the second information. Correspondingly, the base station receives the uplink information through the OCC length corresponding to the seventh parameter.

[0214] For example, the seventh parameter is N1. The terminal receives N1, and determines the OCC length as 2 according to the correspondence between N1 and the OCC length. Thus, the terminal can use the OCC with the length of 2 to encode the uplink information to be sent. Thus, the base station can receive the uplink information through the OCC with the length of 2. Thus, the base station does not need to indicate the OCC length, and the terminal can also implement the OCC encoding.

[0215] For another example, the sixth parameter and the first parameter are the same parameter, and the first information and the second information can be the same information. The seventh parameter is N1. The terminal receives N1, and can determine the OCC length as 2 according to the correspondence between N1 and the OCC length, and determine the OCC within the OCC category symbol according to the correspondence between N1 and the OCC category. Thus, the terminal can use the OCC with the length of 2, the OCC within the OCC category symbol, and encode the uplink information to be sent according to the received OCC sequence. The base station can receive the uplink information through the OCC with the length of 2, the OCC within the OCC category symbol, and the known OCC sequence of the terminal. Thus, the base station does not need to indicate the OCC length and the OCC category, but only indicates the parameter corresponding to the OCC length and the OCC category, and the terminal can also implement the OCC encoding.

[0216] The above describes the communication between the terminal and the base station under the NTN architecture. In addition, the method provided in the embodiments of the present application can be applied under other architectures. The communication method provided in the embodiments of the present application can also be applied under the TN architecture. The base station can be a base station arranged on the ground, and the base station can communicate with the terminal without passing through the ground station. For example, when the terminal sends the first message, the base station can directly receive the first message through the air interface, and can not pass through the ground station. The base station can also receive information from the core network without passing through the ground station.

[0217] The name of the dimension to which the first parameter belongs is not specifically limited in the embodiments of the present application. With the evolution of wireless communication technology, the above dimensions can also have other names. For example, TBS, coding and modulation mode, repetition mode of PUSCH, mapping mode of PUSCH, etc. can have new names with the evolution of technology.
