[0151] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0152] In some embodiments, network device 102 may include at least one of access network device and core network device.

[0153] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

[0154] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0155] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0156] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of the aforementioned one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Protocol Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

[0157] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0158] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0159] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), 6th generation mobile communication system (6G), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0160] Optionally, the 6th generation mobile communication system (6G) network supports access to terminals with different capabilities (e.g., high-end terminals and low-end terminals) to achieve a smart converged network. High-end terminals include Enhanced Mobile Broadband (EMBB) terminals (User Equipment (UE), mobile phones, etc.). Low-end terminals include Reduced Capability (Redcap) terminals (e.g., wristband devices, health monitoring devices) or Enhanced Machine-Type Communication (EMTC) devices. For example, low-end terminals have a battery life of 1 to 2 weeks, while high-end terminals have a battery life of 1 to 2 days.

[0161] Optionally, NR downlink transmission supports three tables: 64th-order Quadrature Amplitude Modulation (QAM), 256QAM, and 64QAM-Low Spectral Efficiency (Low SE). Each table uses a 5-bit overhead to define the Modulation and Coding Scheme (MCS) index meaning, as shown in Tables 1, 2, and 3 below. Table 1 shows the MCS table 1 (64QAM) for the Physical Downlink Shared Channel (PDSCH), which is the default supported table and is used for data transmission when RRC has not established a connection or when no other tables are configured after a connection is established. Table 2 shows the MCS table 2 (256QAM) for PDSCH, which is suitable for high-rate embb services. Table 3 shows the MCS table 3 (64QAM-low SE) for PDSCH, which is suitable for low code rates to achieve high reliability for UR LLC services.

[0162] Table 1

[0163] Table 2

[0164] Table 3

[0165] Optionally, NR uplink also supports 256QAM, 64-lowSEQAM, and 64QAM. If transport precoding is not enabled, the three uplink MCS tables are the same as the three downlink MSC tables. If transport precoding is enabled, the design of the 256QAM table is the same for both uplink and downlink transmissions. The other two, 64-lowSEQAM and 64QAM, are designed separately for uplink, as shown in Tables 4 and 5 below. Table 4 shows the MCS table for PUSCH using transport precoding and 64QAM. Table 5 shows the MCS table for PUSCH using transport precoding and 64QAM (low SE).

[0166] Table 4

[0167] Table 5

[0168] Optionally, in the table above, MCS Index refers to the MCS index; Modulation Order refers to the modulation order; Target code Rate refers to the target code rate; Spectral efficiency refers to the spectral efficiency; and reserved refers to reserved bits.

[0169] Optionally, the 256QAMMCS table is mainly applicable to high-rate eMBB services, and NRembb terminals need to support the configuration of the 256QAMMCS table; the 64QAM-LowSEMCS table is for URLLC services, aiming to increase the coding redundancy of data transmission by reducing the code rate, thereby achieving the high reliability requirements of URLLC services. This table is configured according to the terminal capabilities. Network devices (such as base stations) can only be configured if the terminal supports the 64QAM-LowSE table when reporting user capabilities; the uplink and downlink of NRembb terminals use the 64QAMMCS table as the default supported table for data transmission when RRC has not established a connection or when no other tables are configured after the connection is established.

[0170] Optionally, for 5G RedCap terminals, to minimize the impact of standardization, no new MCS and Channel Quality Indication (CQI) tables are designed for uplink and downlink. Instead, the 256QAM, 64QAM, and 64QAM LowSE tables from NR uplink and downlink are still used as the MCS / CQI tables for RedCap UE. Simultaneously, the 64QAM MCS table remains the default table. This default table is used for data transmission when the terminal's RRC connection is not established or when no other tables are configured after the RRC connection is established. Furthermore, the 256QAM MCS table is optional support for RedCap; RedCap downlink may not support the 256QAM table.

[0171] Optionally, for 6G, the peak rate is 10 to 100 times that of 5G, reaching 100Gbps to 1Tbps. For high-capacity terminals, such as UEs, to support high uplink and downlink transmission rates, 256QAM may be used as the default table, or an MCS table with a higher order than 256QAM may be designed as the default table. However, for low-capacity terminals, such as Redcap terminals, only 64QAM MCS tables are supported as the default table for uplink and downlink. This is because, to ensure low cost, it is impossible to support higher-order MCS tables as the default table. Moreover, 256QAM modulation is an optional modulation scheme supported by Redcap.

[0172] Optionally, when both high-capacity and low-capacity terminals are connected to the 6G network, the default MCS tables supported by the two types of terminals for uplink and downlink are different. If no other tables are configured after the RRC connection is established, and the default tables are used for data transmission, then the network device needs to use different default tables to send downlink data to the low-capacity and high-capacity terminals respectively. Otherwise, if an MCS table higher than the terminal's capability is used, the terminal will not be able to decode the downlink information. For uplink transmission, since the default MCS tables supported by low-end and high-end terminals are different, terminals of both capabilities can also use their respective supported default MCS tables to send uplink data to the network device. The network device needs to obtain the terminal type and use the MCS tables supported by the low-end and high-end terminals respectively to demodulate the uplink transmission. Therefore, if different default tables are defined for high-end and low-end terminals for uplink and / or downlink transmission, the network device needs to determine the terminal type to ensure that the MCS table supported by the terminal is used for terminal scheduling.

[0173] Optionally, the terminal may notify the network device of its terminal type during random access. The network device identifies which terminals are low-end and which are high-end, and performs uplink and / or downlink scheduling for the two types of terminals using the default MCS tables supported by the high-end and low-end terminals, respectively.

[0174] Optionally, the terminal may implicitly indicate a first type to the network device during random access, whereby the first type represents the terminal type of "the terminal".

[0175] Optionally, in embodiments of this disclosure, the first type may refer to a specific terminal type. This "specific terminal" may indicate the first type to the network device, which can identify the first type of the "specific terminal," determine the MCS table supported by the "specific terminal" based on the first type, and perform uplink and / or downlink scheduling on the terminal. Here, the "specific terminal" can be any single terminal or any type of terminal.

[0176] Optionally, in embodiments of this disclosure, "terminal type" can refer to a general type of terminal. For example, "terminal type" can refer to any one or any type of terminal. There can be multiple "terminal types," and the first type is one of the multiple "terminal types."

[0177] Figure 2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure relate to a communication method that can be used in a communication system 100, and are not limited thereto. The above method includes:

[0178] Step S2101: The network device configures the root sequence index for the terminal.

[0179] Optionally, in some embodiments, the network device is, for example, a base station, and the terminal is, for example, a UE.

[0180] Optionally, in some embodiments, the base station can configure a root sequence index for the UE.

[0181] Optionally, in some embodiments, the root sequence index is used to generate the preamble sequence.

[0182] Optionally, in some embodiments, the root sequence index may be referred to as the logical root sequence index. The preamble sequence may be referred to as the preamble sequence. The "logical root sequence index" is used to generate the preamble sequence.

[0183] Optionally, in some embodiments, the root sequence index is an optional example of the first information. The first information is used by the terminal to send a preamble to the network device. The first information can be associated with a first type, which represents the type of "terminal" shown in this embodiment. The first type can be, for example, a high-end terminal or a low-end terminal; of course, the first type can also be any other possible type. Optionally, when the first information is a root sequence index, it means that the root sequence index can be associated with the first type. That is to say, the root sequence index can be a root sequence index associated with the first type configured by the network device for the terminal. Then, the network device can determine the first type of the terminal based on the root sequence index associated with the first type.

[0184] Optionally, in some embodiments, the network device can configure different root sequence index sets for different terminal types, with different terminal types associated with root sequence indices in different root sequence index sets. That is, there can be multiple terminal types, and the first type can be one of multiple terminal types. The network device can configure a root sequence index set for each terminal type, and each root sequence index set contains multiple root sequence indices. Different terminal types are associated with root sequence indices in different root sequence index sets, while the first type is associated with the root sequence indices in the root sequence index set configured for it.

[0185] Optionally, in some embodiments, the number of root sequence index sets is the same as the number of terminal types. This allows for the configuration of a corresponding root sequence index set for each terminal type. When the root sequence index set is used to indicate the first type to the network device, the accuracy of the first type indication can be effectively ensured, enabling the network device to accurately determine the first type.

[0186] In step S2102, the terminal generates a preamble sequence based on the root sequence index.

[0187] Optionally, in some embodiments, the preamble sequence may be referred to as a preamble or a random access sequence.

[0188] Optionally, in some embodiments, the terminal may determine the root sequence index configured for the terminal by the network device, and generate a preamble sequence based on the root sequence index.

[0189] Optionally, in some embodiments, the UE may determine the root sequence index configured by the base station for the UE, and generate a preamble sequence based on the root sequence index.

[0190] Optionally, in some embodiments, the terminal may determine the root sequence index set associated with the first type from multiple root sequence index sets configured by the network device based on the first type of the terminal, generate a preamble sequence using the root sequence index in the root sequence index set associated with the first type, and send the preamble sequence to the network device.

[0191] Optionally, in some embodiments, the root sequence index can be associated with a first type. The terminal can generate a preamble sequence based on the root sequence index. The generated preamble sequence can be used by the network device to determine the first type. For details, please refer to the following embodiments.

[0192] In step S2103, the terminal sends a preamble sequence to the network device.

[0193] Optionally, in some embodiments, after generating the preamble sequence based on the root sequence index, the terminal can send the preamble sequence to the network device.

[0194] Optionally, in some embodiments, the preamble includes at least one of the following: a preamble in message 1 (Msg1) of a four-step random access procedure; or a Physical Random Access Channel (PRACH) in message A (msgA) of a two-step random access procedure. That is, the terminal can indicate the first type to the network device based on either the four-step or two-step random access procedure, thereby enabling accurate and flexible indication of the first type to the network device during the random access process, ensuring that the network device accurately knows the first type.

[0195] Optionally, in some embodiments, the UE may send a preamble sequence to the base station. For example, the UE may generate a preamble (or preamble sequence) in message 1 of a four-step random access procedure based on the root sequence index, and send the preamble (or preamble sequence) to the base station during the four-step random access procedure. For example, the UE may generate the Physical Random Access Channel (PRACH) (an optional example of a preamble sequence) in message A of a two-step random access procedure based on the root sequence index, and send the PRACH to the base station during the two-step random access procedure.

[0196] In step S2104, the network device determines the root sequence index based on the preamble sequence.

[0197] Optionally, in some embodiments, the network device may receive a preamble sequence sent by the terminal and determine the root sequence index based on the preamble sequence.

[0198] Optionally, in some embodiments, the base station may receive a preamble sequence sent by the UE and determine the root sequence index based on the preamble sequence.

[0199] Optionally, in some embodiments, the base station may receive a preamble (or preamble sequence) sent by the UE during a four-step random access process and determine the root sequence index based on the preamble (or preamble sequence). Alternatively, the base station may receive a PRACH sent by the UE during a two-step random access process and determine the root sequence index based on the PRACH.

[0200] In step S2105, the network device determines the first type based on the root sequence index.

[0201] Optionally, in some embodiments, since the root sequence index set configured by the network device for the first type of terminal is associated with the first type, and the root sequence index set contains multiple root sequence indices, that is, the root sequence index is associated with the first type, when the terminal generates and sends a preamble sequence based on the root sequence index, after the network device receives the preamble sequence, it can determine the first type based on the root sequence index used by the terminal to send the preamble sequence.

[0202] For example, a terminal can notify the network device of its terminal type via a preamble (e.g., the preamble of Msg1 or the PRACH of msgA) (an optional example of the first type mentioned above). That is, the terminal can notify the network device of its terminal type based on the preamble sequence used by the UE (an optional example of the first type mentioned above). The network device configures different sets of logical root sequence indices for different terminal types. When the network device receives a preamble generated by the UE using the root sequence index in set 1, it determines that the UE is a low-end terminal (an optional example of the first type). When the network device receives a preamble generated by the UE using the root sequence index in set 2, it determines that the UE is a high-end terminal (an optional example of the first type).

[0203] For example, the root sequence index is configured by a higher-level parameter (prach-RootSequenceIndex, rootSequenceIndex-BFR, or msgA-PRACH-RootSequenceIndex), which can be included in System Information Block 1 (SIB1). For instance, higher-level parameter 1 (prach-RootSequenceIndex 1) indicates the set of root sequence indices used for generating the preamble for low-end terminals, and prach-RootSequenceIndex 1 indicates the set of root sequence indices used for generating the preamble for high-end terminals. Optionally, for N terminal types, N sets of root sequence indices are configured.

[0204] Step S2106: The network device determines the MCS table supported by the terminal according to the first type.

[0205] Optionally, in some embodiments, after determining the first type, the network device may determine the modulation and coding scheme (MCS) table supported by the terminal based on the first type.

[0206] Optionally, in some embodiments, the MCS table supported by the terminal can be at least one of Tables 1-5 described above. The network device can determine at least one MCS table supported by the terminal from Tables 1-5 based on the determined first type.

[0207] Optionally, in some embodiments, the MCS table supported by the UE can be at least one of Tables 1-5 above. The base station can determine at least one MCS table supported by the UE from Tables 1-5 above based on the determined first type.

[0208] Step S2107: The network device schedules the terminals according to the MCS table.

[0209] Optionally, in some embodiments, the network device can schedule terminals according to an MCS table. For example, the network device can perform uplink scheduling of terminals according to an MCS table, and / or the network device can perform downlink scheduling of terminals according to an MCS table.

[0210] Optionally, in some embodiments, the base station can schedule the UE according to the MCS table. For example, the base station can perform uplink scheduling of the UE according to the MCS table, and / or the base station can perform downlink scheduling of the UE according to the MCS table.

[0211] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2107. For example, steps S2101, S2102, S2103, S2104, S2105, S2106, and S2107 can each be implemented as an independent embodiment. Steps S2101+S2102, S2101+S2103, S2101+S2104, S2101+S2105, S2101+S2106, S2102+S2103, and S2102+S2104 can be implemented as independent embodiments. The steps S2102+S2105, S2102+S2106, S2101+S2102+S2103, S2101+S2102+S2104, S2101+S2102+S2105, S2102+S2103+S2104, S2101+S2102+S2105+S2106, etc., can be implemented as independent embodiments, but are not limited thereto.

[0212] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

[0213] In the embodiments disclosed herein, each step and its optional implementation can also be carried out independently.

[0214] In this embodiment, the network device configures a root sequence index for the terminal. The terminal generates a preamble sequence based on the root sequence index and sends it to the network device. The network device determines the root sequence index based on the preamble sequence, determines a first type based on the root sequence index, determines the Modulation and Coding Scheme (MCS) table supported by the terminal based on the first type, and schedules the terminal according to the MCS table. Thus, the terminal can send the preamble sequence to the network device through the root sequence index configured for it, and the root sequence index can be associated with the first type. The network device can determine the first type based on the root sequence index used by the terminal to send the preamble sequence, thereby effectively indicating the first type to the network device implicitly. The network device can then know the first type, determine the MCS table supported by the terminal based on the first type, and use the supported MCS table to schedule the terminal, thereby improving scheduling accuracy and enhancing system performance.

[0215] It should be noted that the descriptions of the same or corresponding terms and method steps in the following embodiments can be found in the above embodiments, and will not be repeated here.

[0216] Figure 2B is an interactive schematic diagram of a communication method according to another embodiment of the present disclosure. As shown in Figure 2B, the embodiments of the present disclosure relate to a communication method that can be used in a communication system 100, and are not limited thereto. The above method includes:

[0217] Step S2201: The terminal determines the random access sequence configured by the network device, or determines a predefined random access sequence.

[0218] Optionally, in some embodiments, the network device can configure different sets of random access sequences for different terminal types, with different terminal types associated with random access sequences in different sets of random access sequences.

[0219] Optionally, in some embodiments, different sets of random access sequences can be predefined for different terminal types, and different terminal types can be associated with random access sequences in different sets of random access sequences.

[0220] Optionally, in some embodiments, the random access sequence is an optional example of the first information. The first information is used by the terminal to send a preamble to the network device. The first information can be associated with a first type, which represents the type of the "terminal" shown in this embodiment. The first type can be, for example, a high-end terminal or a low-end terminal; of course, the first type can also be any other possible type. Optionally, when the first information is a random access sequence, it means that the random access sequence can be associated with the first type. That is to say, the random access sequence can be a random access sequence in a set of random access sequences associated with the first type configured by the network device for the terminal or predefined. Then, the network device can determine the first type of the terminal based on the random access sequence associated with the first type.

[0221] Optionally, in some embodiments, the network device can configure different sets of random access sequences for different terminal types, or can predefine different sets of random access sequences for different terminal types, with different terminal types associated with random access sequences in different sets of random access sequences. That is, there can be multiple terminal types, and the first type can be one of multiple terminal types. The network device can configure a set of random access sequences for each terminal type, and each set of random access sequences contains multiple random access sequences. Different terminal types are associated with random access sequences in different sets of random access sequences, while the first type is associated with the random access sequences in its configured set of random access sequences.

[0222] Optionally, in some embodiments, the number of random access sequence sets is the same as the number of terminal types. This allows for the configuration of a corresponding random access sequence set for each terminal type. When the random access sequence set is used to indicate the first type to the network device, the accuracy of the first type indication can be effectively ensured, enabling the network device to accurately determine the first type.

[0223] Optionally, in some embodiments, the terminal may determine a set of random access sequences associated with the first type from a plurality of random access sequence sets configured or predefined by the network device based on the first type of the terminal, and send a preamble to the network device using the random access sequence in the set of random access sequences associated with the first type.

[0224] In step S2202, the terminal sends a preamble to the network device through a random access sequence.

[0225] Optionally, in some embodiments, after determining the random access sequence associated with the first type, the terminal may use the random access sequence to send a preamble to the network device.

[0226] Optionally, in some embodiments, after determining the random access sequence associated with the first type, the UE can use the random access sequence to send a preamble to the base station.

[0227] Optionally, in some embodiments, the UE can send a preamble to the base station via a random access sequence. For example, the UE can send a preamble to the base station via a random access sequence during a four-step random access process. For example, the UE can send a PRACH to the base station via a random access sequence during a two-step random access process.

[0228] In step S2203, the network device determines the random access sequence based on the preamble.

[0229] Optionally, in some embodiments, the network device may receive a preamble sent by the terminal and determine the random access sequence used by the terminal to send the preamble based on the preamble.

[0230] Optionally, in some embodiments, the base station may receive a preamble sent by the UE and determine the random access sequence used by the UE to send the preamble based on the preamble.

[0231] Optionally, in some embodiments, the base station may receive a preamble sent by the UE during a four-step random access process and determine the random access sequence based on the preamble. Alternatively, the base station may receive a PRACH sent by the UE during a two-step random access process and determine the random access sequence based on the PRACH.

[0232] Step S2204: The network device determines the first type based on the random access sequence.

[0233] Optionally, in some embodiments, since a set of random access sequences configured or predefined for a terminal of the first type is associated with the first type, and the set of random access sequences contains multiple random access sequences, that is, the random access sequences are associated with the first type, when a terminal sends a preamble based on the random access sequence, after the network device receives the preamble, it can determine the first type based on the random access sequence used by the terminal to send the preamble.

[0234] Alternatively, in some embodiments, the random access sequence may be referred to as a preamble sequence, sequence, preamble sequence, etc.

[0235] Optionally, in some embodiments, the set of random access sequences may be referred to as the set of preamble sequences.

[0236] For example, high-end terminals and low-end terminals use preamble sequences from different random access sequence sets. If the UE uses a sequence from random access sequence set 1 to transmit on the PRACH, it means the UE is a high-end terminal. If the UE uses a sequence from random access sequence set 2 to transmit on the PRACH, it means the UE is a low-end terminal.

[0237] For example, a set of random access sequences, 1, is predefined for low-end terminals, and a set of random access sequences, 2, is predefined for high-end terminals. Low-end terminals use sequences from set 1 to send a preamble to the network device, while high-end terminals use sequences from set 2 to send a preamble to the network device.

[0238] For example, a network device configures different sets of random access sequences for different terminal types. For instance, the network device might configure the following: Random access sequence set 1 {sequence 1, sequence 2, sequence 3, ..., sequence N} is provided to low-end terminals, and random access sequence set 2 {sequence 1, sequence 2, sequence 3, ..., sequence M} is provided to high-end terminals. The network device predefines random access sequence set 1 and random access sequence set 2. If it receives a preamble from random access sequence set 1 used by a terminal, the network device determines that the terminal is a low-end terminal; if it receives a preamble from random access sequence set 2 used by a terminal, the network device determines that the terminal is a high-end terminal.

[0239] For example, with N terminal types, N sets of preamble sequences are configured.

[0240] In step S2205, the network device determines the MCS table supported by the terminal based on the first type.

[0241] Step S2206: The network device schedules the terminals according to the MCS table.

[0242] The communication method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2206.

[0245] In this embodiment, the terminal generates a preamble based on a random access sequence configured or predefined by the network device. The terminal sends the preamble to the network device, which determines the random access sequence based on the preamble, identifies a first type based on the random access sequence, determines the MCS table supported by the terminal based on the first type, and schedules the terminal according to the MCS table. Thus, the terminal can send a preamble to the network device using a random access sequence configured or predefined by the network device, and the random access sequence can be associated with the first type. The network device can determine the first type based on the random access sequence used by the terminal to send the preamble, thereby effectively indicating the first type to the network device implicitly. The network device can then know the first type, determine the MCS table supported by the terminal based on the first type, and use the supported MCS table to schedule the terminal, thereby improving scheduling accuracy and enhancing system performance.

[0246] Figure 2C is an interactive schematic diagram of a communication method according to another embodiment of the present disclosure. As shown in Figure 2C, the embodiments of the present disclosure relate to a communication method that can be used in a communication system 100, and are not limited thereto. The above method includes:

[0247] Step S2301: The network device configures scrambling codes for the terminal.

[0248] Optionally, in some embodiments, the scrambling code can be an optional example of the first information. The first information is used by the terminal to send a preamble to the network device. The first information can be associated with a first type, which represents the type of "terminal" shown in this embodiment. The first type can be, for example, a high-end terminal or a low-end terminal; of course, the first type can also be any other possible type. Optionally, when the first information is a scrambling code, it means that the scrambling code can be associated with the first type. That is to say, the scrambling code can be a scrambling code associated with the first type configured by the network device for the terminal. Then, the network device can determine the first type of the terminal based on the scrambling code associated with the first type.

[0249] Optionally, in some embodiments, the network device can configure different scrambling codes for different terminal types. That is, there can be multiple terminal types, and the first type can be one of the multiple terminal types. The network device can configure a scrambling code for each terminal type, with different terminal types associated with different scrambling codes, and the first type associated with the scrambling code it is configured with.

[0250] Optionally, in some embodiments, the number of scrambling codes is the same as the number of terminal types, and the lengths of the different scrambling codes may be the same or different. This allows for the configuration of a corresponding scrambling code for each terminal type, effectively ensuring the accuracy of the first type indication when using the scrambling code to indicate the first type to the network device, enabling the network device to accurately determine the first type.

[0251] In step S2302, the terminal scrambles the preamble according to the scrambling code.

[0252] Optionally, in some embodiments, the terminal may determine the scrambling code configured for the terminal by the network device, and use the scrambling code to scramble the preamble to obtain the scrambled preamble.

[0253] Optionally, in some embodiments, the UE can determine the scrambling code configured by the base station for the UE, and use the scrambling code to scramble the preamble to obtain the scrambled preamble.

[0254] Optionally, in some embodiments, the terminal may determine the scrambling code associated with the first type from a plurality of scrambling codes configured by the network device based on the first type of the terminal, and use the scrambling code associated with the first type to scramble the preamble to obtain the scrambled preamble.

[0255] Optionally, in some embodiments, the scrambling code can be associated with a first type. The terminal can scramble the preamble according to the scrambling code, and the scrambled preamble can be used by the network device to determine the first type. For details, please refer to the following embodiments.

[0256] In step S2303, the terminal sends the scrambled preamble to the network device.

[0257] Optionally, in some embodiments, after scrambling the preamble with a scrambling code, the terminal can send the scrambled preamble to the network device.

[0258] Optionally, in some embodiments, the UE may send a scrambled preamble to the base station. For example, the UE may use a scrambling code to scramble the preamble in message 1 of a four-step random access procedure and send the scrambled preamble to the base station during the four-step random access procedure. For example, the UE may use a scrambling code to scramble the PRACH (an optional example of a preamble) in message A of a two-step random access procedure and send the scrambled PRACH to the base station during the two-step random access procedure.

[0259] In step S2304, the network device determines the scrambling code based on the scrambled preamble.

[0260] Optionally, in some embodiments, the network device may receive a scrambled preamble sent by the terminal and determine the lead code based on the scrambled preamble.

[0261] Optionally, in some embodiments, the base station may receive the scrambled preamble sent by the UE and determine the preamble based on the scrambled preamble.

[0262] Optionally, in some embodiments, the base station may receive a scrambled preamble sent by the base station during a four-step random access process and determine the preamble based on the scrambled preamble. Alternatively, the base station may receive a scrambled PRACH sent by the UE during a two-step random access process and determine the preamble based on the scrambled PRACH.

[0263] Optionally, in some embodiments, the network device may use each candidate scrambling code to descramble the received scrambled preamble. If descrambling is successful based on a candidate scrambling code, the candidate scrambling code is determined as the scrambling code used by the terminal.

[0264] In step S2305, the network device determines the first type based on the scrambling code.

[0265] Optionally, in some embodiments, since the scrambling code configured by the network device for the first type of terminal is associated with the first type, when the terminal scrambles the preamble based on the scrambling code to obtain the scrambled preamble, after the network device receives the scrambled preamble, it can determine the first type based on the scrambling code used by the terminal to send the scrambled preamble.

[0266] For example, network devices can configure different scrambling codes for different terminal types through system broadcast messages (Physical Broadcast Channel (PBCH), SIB1, Master Information Block (MIB), Other System Information (OSI), etc.). Different scrambling codes are used to scramble the preamble for different terminal types. If there are N terminal types, then N scrambling codes are configured. The lengths of the different scrambling codes may be equal or unequal, and the length of the scrambling code is L bits.

[0267] For example, consider two terminal types: a high-end terminal and a low-end terminal. The network device broadcasts two scrambling codes: Scrambling code 1 (e.g., 16 characters long, such as 0011100011111000) scrambles the preamble of the low-end terminal, and scrambling code 2 (16 characters long, such as 00111011111111000) scrambles the preamble of the high-end terminal. When the network device receives the preamble (an optional example of the scrambled preamble) sent by the terminal, it uses scrambling code 1 and scrambling code 2 to descramble it. If it can successfully descramble with scrambling code 1, it proves that the preamble was sent by the low-end terminal; if it can successfully descramble with scrambling code 2, it proves that the preamble was sent by the high-end terminal.

[0268] Step S2306: The network device determines the MCS table supported by the terminal according to the first type.

[0269] Step S2307: The network device schedules the terminals according to the MCS table.

[0270] The communication method involved in the embodiments of this disclosure may include at least one of steps S2301 to S2307. For example, steps S2301, S2302, S2303, S2304, S2305, S2306, and S2307 can each be implemented as an independent embodiment. Steps S2301+S2302, S2301+S2303, S2301+S2304, S2301+S2305, S2301+S2306, S2302+S2303, and S2302+S2304 can be implemented as independent embodiments. The steps S2302+S2305, S2302+S2306, S2301+S2302+S2303, S2301+S2302+S2304, S2301+S2302+S2305, S2302+S2303+S2304, S2301+S2302+S2305+S2306, etc., can be implemented as independent embodiments, but are not limited thereto.

[0271] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

[0272] In the embodiments disclosed herein, each step and its optional implementation can also be carried out independently.

[0273] In this embodiment, the network device configures a scrambling code for the terminal. The terminal scrambles the preamble according to the scrambling code and sends the scrambled preamble to the network device. The network device determines the scrambling code based on the scrambling code, determines the first type based on the scrambling code, determines the MCS table supported by the terminal based on the first type, and schedules the terminal according to the MCS table. Thus, the terminal can send the scrambled preamble to the network device using the scrambling code configured for it by the network device, and the scrambling code is associated with the first type. The network device can determine the first type based on the scrambling code used by the terminal, thereby effectively indicating the first type to the network device implicitly. The network device can know the first type, and based on the first type, know the MCS table supported by the terminal, and use the MCS table supported by the terminal to schedule the terminal, thereby improving scheduling accuracy and enhancing system performance.

[0274] Figure 2D is an interactive schematic diagram illustrating a communication method according to another embodiment of the present disclosure. As shown in Figure 2D, the embodiments of the present disclosure relate to a communication method that can be used in a communication system 100, and are not limited thereto. The above method includes:

[0275] Step S2401: The network device configures the preamble transmission resources for the terminal.

[0276] Optionally, in some embodiments, transmission resources are used by the terminal to transmit a preamble. Transmission resources may be, for example, frequency domain resources or time domain resources.

[0277] Optionally, in some embodiments, the network device can configure different preamble transmission resources for different terminal types.

[0278] Optionally, in some embodiments, the transmission resource can be associated with a first type, which represents the type of "terminal" shown in this embodiment. The first type can be, for example, a high-end terminal or a low-end terminal, or any other possible type. That is, the transmission resource can be a transmission resource associated with the first type configured by the network device for the terminal, and the network device can determine the first type of the terminal based on the transmission resource associated with the first type.

[0279] Optionally, in some embodiments, the network device can configure different preamble transmission resources for different terminal types. That is, there can be multiple terminal types, and the first type can be one of multiple terminal types. The network device can configure a transmission resource for each terminal type, and different terminal types are associated with different preamble transmission resources, while the first type is associated with the preamble transmission resources configured for it.

[0280] Optionally, in some embodiments, the number of preamble transmission resources is the same as the number of terminal types. This allows for the configuration of corresponding preamble transmission resources for each terminal type. When the preamble transmission resources are used to indicate the first type to the network device, the accuracy of the first type indication can be effectively ensured, enabling the network device to accurately determine the first type.

[0281] In step S2402, the terminal sends a preamble to the network device according to the transmission resources.

[0282] Optionally, in some embodiments, the terminal may determine the transmission resources configured for the terminal by the network device, and send a preamble to the network device according to the transmission resources.

[0283] Optionally, in some embodiments, the UE may determine the transmission resources configured by the base station for the UE, and send a preamble to the base station according to the transmission resources.

[0284] Optionally, in some embodiments, the terminal may determine the transmission resource associated with the first type from a plurality of transmission resources configured by the network device based on the first type of the terminal, and use the transmission resource associated with the first type to send a preamble to the network device.

[0285] Optionally, in some embodiments, the transmission resource can be associated with a first type. The terminal can send a preamble to the network device based on the transmission resource. The sent preamble can be used by the network device to determine the first type. For details, please refer to the following embodiments.

[0286] Optionally, in some embodiments, the UE may use transmission resources to send a preamble to the base station. For example, the UE may use transmission resources associated with the first type to send a preamble to the base station during a four-step random access process. For example, the UE may use transmission resources associated with the first type to send a PRACH to the base station during a two-step random access process.

[0287] In step S2403, the network device determines the transmission resource based on the preamble.

[0288] Optionally, in some embodiments, the network device may receive a preamble sent by the terminal and determine the transmission resources used by the terminal to send the preamble.

[0289] Optionally, in some embodiments, the base station may receive the preamble sent by the UE and determine the transmission resources used by the UE to send the preamble.

[0290] Optionally, in some embodiments, the base station may receive the preamble sent by the UE during a four-step random access process and determine the transmission resources used by the UE to send the preamble. Alternatively, the base station may receive the PRACH sent by the UE during a two-step random access process and determine the transmission resources used by the UE to send the PRACH.

[0291] In step S2404, the network device determines the first type based on the transmission resources.

[0292] Optionally, in some embodiments, since the transmission resources configured by the network device for the first type of terminal are associated with the first type, when the terminal sends a preamble based on the transmission resources, after the network device receives the preamble, it can determine the first type based on the transmission resources used by the terminal to send the preamble.

[0293] For example, the network device is notified of the terminal type (an optional example of the first type mentioned above) based on the resource on which the UE sends the preamble (Msg1 or msgAPRACH). For the preamble, the base station configures a first resource and a second resource for sending the preamble for different UE types (an optional example of the terminal types mentioned above) through higher-layer parameters. The first resource is used for random access by high-end terminals, and the second resource is used for random access by low-end terminals. The UE selects to use the first resource or the second resource to send the preamble according to its own type (an optional example of the first type mentioned above). When the base station receives the preamble sent by the UE on a specific resource, the base station determines the UE type based on the resource used by the UE. If the base station receives the preamble initiated by the terminal on the first resource, the base station knows that the terminal is a high-end terminal; if the base station receives the preamble initiated by the terminal on the second resource, the base station knows that the terminal is a low-end terminal. For msgAPRACH, the base station configures first and second resources for transmitting msgAPRACH for different UE types through higher-layer parameters. The first resource is used by high-end terminals, and the second resource is used by low-end terminals. The UE chooses to use either the first or second resource to transmit msgAPRACH based on its type. When the base station receives the msgAPRACH transmitted by the UE on a specific resource, it determines the UE type based on the resource used. If the base station receives the msgAPRACH initiated by the terminal on the first resource, it knows that the terminal is a high-end terminal; if the base station receives the msgAPRACH initiated by the terminal on the second resource, it knows that the terminal is a low-end terminal. For example, if there are N types of terminals accessing a 6G network, then the first resource, ..., and the Nth resource can be configured for transmitting either msg1 or msgAPRACH for each of the N terminal types.

[0294] For example, if there are more than two terminal types, such as three terminal types, you can configure a first resource, a second resource, and a third resource.

[0295] For example, in a four-step random access procedure, the higher-layer parameter `higher-layer-parameter-prach-ConfigurationIndex` configures the first and second time-domain resources for transmitting the preamble, and the higher-layer parameter `msg1-FrequencyStart` configures the first and second frequency-domain resources for transmitting the preamble. The first time-frequency domain resource is the first resource, used by high-end terminals to transmit the preamble, and the second time-frequency domain resource is the second resource, used by low-end terminals to transmit the preamble. If a terminal uses the first resource to transmit the preamble, the base station receives the preamble on the first resource and determines that the terminal is a high-end terminal. If a terminal uses the second resource to transmit the preamble, the base station receives the preamble on the second resource and determines that the terminal is a low-end terminal.

[0296] For example, in a two-step random access procedure, the higher-layer parameter msgA-PRACH-ConfigurationIndex configures first and second time-domain resources for transmitting msgAPRACH for different terminal types. The higher-layer parameter msgA-RO-FrequencyStart configures first and second frequency-domain resources for transmitting msgAPRACH for different terminal types. The first time-frequency domain resource, i.e., the first resource, is used for high-end terminals to transmit msgAPRACH, and the second time-frequency domain resource, i.e., the second resource, is used for low-end terminals to transmit msgAPRACH. If a terminal uses the first resource to transmit msgAPRACH, the base station receives the terminal's msgAPRACH on the first resource and determines that the terminal is a high-end terminal. If a terminal uses the second resource to transmit msgAPRACH, the base station receives the terminal's msgAPRACH on the second resource and determines that the terminal is a low-end terminal.

[0297] In step S2405, the network device determines the MCS table supported by the terminal according to the first type.

[0298] Step S2406: The network device schedules the terminals according to the MCS table.

[0299] The communication method involved in the embodiments of this disclosure may include at least one of steps S2401 to S2406. For example, steps S2401, S2402, S2403, S2404, S2405, and S2406 can each be implemented as an independent embodiment. Steps S2401+S2402, S2403, S2404, S2405, and S2406 can be implemented as independent embodiments. Steps S2402+S2403, S2404, and S2405 can be implemented as independent embodiments.

[0301] In the embodiments disclosed herein, each step and its optional implementation can also be carried out independently.

[0302] In this embodiment, the network device configures preamble transmission resources for the terminal. The terminal sends a preamble to the network device based on these resources. The network device determines the transmission resources used by the terminal based on the preamble, determines a first type based on these resources, determines the MCS table supported by the terminal based on the first type, and schedules the terminal according to the MCS table. Thus, the terminal can send a preamble to the network device using the preamble transmission resources configured for it, and these transmission resources are associated with the first type. The network device can determine the first type based on the transmission resources used by the terminal to send the preamble, effectively implicitly indicating the first type to the network device. The network device can then know the first type, determine the MCS table supported by the terminal based on the first type, and use the supported MCS table to schedule the terminal, thereby improving scheduling accuracy and system performance.
