Background Art

[0002] In current communication systems, when a base station communicates with a terminal, the base station supports full-duplex mode. For the terminal, since the terminal is generally small in size and has limited ability to suppress self-interference, it generally only supports half-duplex mode. However, in some cases, full-duplex can also be achieved.

[0003] Although full-duplex mode can bring benefits such as increased throughput, reduced transmission latency, and enhanced uplink coverage, these benefits are not applicable in all scenarios. In some cases, communication in full-duplex mode may also cause some problems. Summary of the Invention

[0028] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0029] The terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the embodiments of the present disclosure. The singular forms "a," "an," and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0030] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0031] For the purpose of brevity and ease of understanding, the terms "greater than," "less than," "higher than," and "lower than" are used herein to describe size relationships. However, those skilled in the art will understand that the term "greater than" also encompasses the meaning of "greater than or equal to," and "less than" also encompasses the meaning of "less than or equal to," and the term "higher than" also encompasses the meaning of "higher than or equal to," and "lower than" also encompasses the meaning of "lower than or equal to."

[0032] Although full-duplex mode can bring benefits such as increased throughput, reduced transmission latency, and enhanced uplink coverage, these benefits are not applicable in all scenarios. In some cases, communication in full-duplex mode may also cause some problems.

[0033] For example, for a base station, full-duplex mode communication can easily interfere with the uplink transmission of other base stations; for a terminal, full-duplex mode communication can hardly ensure good communication quality due to poor ability to suppress self-interference.

[0034] It can be seen that for base stations and terminals that support half-duplex mode and full-duplex mode, always communicating based on full-duplex mode will cause some technical problems. How to flexibly adjust the duplex mode to adapt to actual conditions is the main technical problem solved by this disclosure.

[0035] Figure 1The present invention is a schematic flow chart illustrating a method for indicating an operating mode according to an embodiment of the present disclosure. The operating mode indication method illustrated in this embodiment can be executed by a terminal, including but not limited to a mobile phone, tablet computer, wearable device, sensor, IoT device, and other communication devices. The terminal can communicate with network-side devices, including but not limited to network-side devices in 4G, 5G, 6G, and other communication systems, such as base stations and core networks.

[0036] like Figure 1 As shown, the working mode indication method may include the following steps:

[0037] In step S101, indication information is sent to a network side device to indicate the duplex mode information of the terminal to the network side device.

[0038] In one embodiment, the terminal may send indication information to the network-side device, and based on the indication information, the network-side device may determine the duplex mode of the terminal.

[0039] In one embodiment, the duplex mode information of the terminal includes at least one of the following:

[0040] duplex modes supported by the terminal;

[0041] It is expected that the network-side device schedules a duplex mode to be adopted by the terminal;

[0042] The duplex mode that the network-side device is expected to adopt.

[0043] In one embodiment, the duplex mode includes at least a half-duplex mode and a full-duplex mode. The full-duplex mode refers to performing uplink transmission and downlink transmission simultaneously in the same frequency domain resources.

[0044] For example, for network-side devices, full-duplex mode means that uplink transmission and downlink reception are performed simultaneously in the same time domain resources, such as the same time slot. The uplink transmission and downlink reception can be performed for different terminals or for the same terminal.

[0045] For example, for a terminal, full-duplex mode refers to simultaneous uplink transmission and downlink reception in the same time domain resource, such as the same time slot, where the time slot includes at least one of the following: a downlink slot in the time division duplexing (TDD) frequency band, an uplink slot in the TDD frequency band, and a slot in the frequency division duplexing (FDD) frequency band.

[0046] In addition, for network-side devices, full-duplex modes can include subband-based full-duplex (SBFD) and shared spectrum full-duplex (SSFD). SBFD can be further divided into two full-duplex modes: non-overlapping subband and partial overlapping subband.

[0047] In one embodiment, based on the indication information sent by the terminal, the network side device can determine the duplex mode supported by the terminal, for example, it can be determined that the terminal only supports half-duplex mode, or only supports full-duplex mode, or supports both half-duplex mode and full-duplex mode.

[0048] Based on this, the network side device can determine which duplex mode the terminal can be scheduled to adopt in the future.

[0049] In one embodiment, based on the indication information sent by the terminal, the network side device can determine the duplex mode that the terminal expects the network side device to schedule the terminal to adopt. For example, when the terminal supports both half-duplex mode and full-duplex mode, the duplex mode that the terminal expects the network side device to schedule the terminal to adopt may be only half-duplex mode, or only full-duplex mode, or both full-duplex mode and half-duplex mode.

[0050] Based on this, the network side device can determine which duplex mode the terminal needs to adopt in the subsequent scheduling.

[0051] The duplex mode supported by the terminal includes the duplex mode that the terminal expects the network side device to schedule the terminal to adopt, that is, the terminal does not expect the network side device to schedule the terminal to adopt a duplex mode that the terminal does not support.

[0052] In one embodiment, based on the indication information sent by the terminal, the network side device can determine the duplex mode that the terminal expects the network side device to adopt, for example, the terminal expects the network side to adopt full-duplex mode, or half-duplex mode, or both full-duplex mode and half-duplex mode.

[0053] Based on this, the network side device can determine which duplex mode it needs to adopt subsequently. Of course, the duplex mode actually adopted by the subsequent network side device may be different from the duplex mode that the terminal expects the network side device to adopt. The specific duplex mode can be determined by the network side device according to needs. However, when both full-duplex mode and half-duplex mode are available, the duplex mode that the terminal expects the network side device to adopt can be preferentially adopted to meet the needs of the terminal.

[0054] According to an embodiment of the present disclosure, the terminal can send indication information to the network side device so that the network side device can know the duplex mode information of the terminal, so as to subsequently schedule the terminal to adopt an appropriate duplex mode according to actual conditions, thereby avoiding problems caused by the duplex mode adopted by the terminal not matching the actual conditions.

[0055] In one embodiment, if the network side device does not determine whether the terminal supports full-duplex mode, then when scheduling the duplex mode adopted by the terminal, the terminal is only scheduled to adopt half-duplex mode. For example, for a certain time slot, the terminal will only be scheduled to perform uplink transmission or downlink reception on the time slot, so as to avoid scheduling the terminal to adopt full-duplex mode when the terminal does not support full-duplex and causing communication problems.

[0056] In one embodiment, the indication information sent by the terminal to the network side device may be explicit indication information or implicit indication information. The following exemplifies the explicit indication and implicit indication cases through several embodiments.

[0057] Figure 2 FIG. 1 is a schematic flow chart of another working mode indication method according to an embodiment of the present disclosure. Figure 2 As shown, the duplex mode information of the terminal includes the duplex mode supported by the terminal, and the sending of the indication information to the network side device includes:

[0058] In step S201, type information of the terminal is sent to the network-side device, wherein the type information is associated with whether the terminal supports full-duplex mode.

[0059] In one embodiment, the terminal may report its own type information to the network side device. The network side device may pre-store the association between the terminal type information and whether the terminal supports full-duplex mode, and then determine whether the terminal supports full-duplex mode based on the terminal type information.

[0060] For example, type A is associated with the terminal supporting full-duplex mode, and type B is associated with the terminal not supporting full-duplex mode. When the indication information received by the network side device is type A, it can be determined that the terminal supports full-duplex mode. When the indication information received is type B, it can be determined that the terminal does not support full-duplex mode.

[0061] Based on this approach, the terminal can implicitly indicate to the network-side device whether the terminal supports the full-duplex mode by reporting the terminal type information to the network-side device.

[0062] Figure 3 FIG. 1 is a schematic flow chart of another working mode indication method according to an embodiment of the present disclosure. Figure 3As shown, the duplex mode information of the terminal includes the duplex mode supported by the terminal, and the sending of the indication information to the network side device includes:

[0063] In step S301, capability information of the terminal is sent to the network-side device, wherein the capability information of the terminal is used to indicate a duplex mode supported by the terminal.

[0064] In one embodiment, the terminal can explicitly indicate to the network device the duplex modes it supports. For example, the capability information may indicate that the terminal only supports half-duplex mode, or only supports full-duplex mode, or supports both half-duplex mode and full-duplex mode. In addition to this indication method, the terminal may default to supporting half-duplex mode, and the capability information may indicate whether the terminal supports full-duplex mode based on this.

[0065] Figure 4 FIG. 1 is a schematic flow chart of another working mode indication method according to an embodiment of the present disclosure. Figure 4 As shown, the duplex mode information of the terminal includes the duplex mode that the network side device expects the terminal to use in scheduling, and the sending of the indication information to the network side device includes:

[0066] In step S401, the indication information is sent to the network side device during the random access process.

[0067] In one embodiment, the terminal can send the indicated indication information to the network side device on appropriate resources as needed. For example, the indication information can be sent to the network side device during the random access process. Accordingly, it can be ensured that during the random access process, the network side device can determine the duplex mode information of the terminal so that after the communication connection is subsequently established, the terminal can be scheduled to adopt the appropriate duplex mode as soon as possible, or the duplex mode expected by the terminal can be adopted as soon as possible.

[0068] Figure 5 FIG. 1 is a schematic flow chart of another working mode indication method according to an embodiment of the present disclosure. Figure 5 As shown, the sending of the indication information to the network side device during the random access process includes:

[0069] In step S501, a random access preamble is sent to the network side device, wherein the preamble is associated with a duplex mode desired by the terminal.

[0070] In one embodiment, the terminal and the network-side device may pre-store a first association between a preamble (for example, a preamble index) and a duplex mode desired by the terminal. After determining the duplex mode desired by the terminal, the preamble corresponding to the duplex mode desired by the terminal may be determined based on the first association, and the determined preamble may be sent to the network-side device. After receiving the preamble sent by the terminal, the network-side device may determine the duplex mode desired by the terminal corresponding to the preamble based on the first association.

[0071] Figure 6 FIG. 1 is a schematic flow chart of another working mode indication method according to an embodiment of the present disclosure. Figure 6 As shown, the sending of the indication information to the network side device during the random access process includes:

[0072] In step S601, indication information is sent to the network side device at a specific random access occasion (Radom Access Occasion, RO), wherein the specific random access occasion is associated with a duplex mode desired by the terminal.

[0073] In one embodiment, the terminal and the network-side device may pre-store a second association between a random access opportunity and a duplex mode desired by the terminal. After determining the duplex mode desired by the terminal, the terminal and the network-side device may determine a specific random access opportunity corresponding to the duplex mode desired by the terminal based on the second association, and then send indication information, such as a random access message, to the network-side device at the specific random access opportunity as the indication information. Upon receiving the random access message sent by the terminal at the specific random access opportunity, the network-side device may determine the duplex mode desired by the terminal corresponding to the specific random access opportunity based on the second association.

[0074] In one embodiment, sending the indication information to the network side device during the random access process includes: sending a random access message Msg3 or MsgA to the network side device, wherein the random access message carries indication information associated with the duplex mode desired by the terminal.

[0075] During the four-step random access process, the terminal may carry indication information in the random access message Msg3 and send it to the network side device; during the two-step random access process, the terminal may carry indication information in the random access message MsgA and send it to the network side device.

[0076] Figure 7This is a schematic flow chart illustrating a method for determining an operating mode according to an embodiment of the present disclosure. The operating mode determination method illustrated in this embodiment can be executed by a network-side device, including but not limited to network-side devices in 4G, 5G, and 6G communication systems, such as base stations and core networks. The network-side device can communicate with terminals, including but not limited to mobile phones, tablets, wearable devices, sensors, IoT devices, and other communication devices.

[0077] like Figure 7 As shown, the working mode determination method may include the following steps:

[0078] In step S701, duplex mode information of the terminal is determined according to at least one of the following:

[0079] Instruction information sent by the terminal;

[0080] Channel State Information (CSI) sent by the terminal;

[0081] power parameters configured for the terminal;

[0082] Interference related information.

[0083] In one embodiment, the duplex mode information of the terminal includes at least one of the following:

[0084] duplex modes supported by the terminal;

[0085] It is expected that the network-side device schedules a duplex mode to be adopted by the terminal;

[0086] The terminal expects the network-side device to adopt a duplex mode.

[0087] It should be noted that, in addition to determining the duplex mode information of the terminal, the network-side device can also determine the duplex mode that the network-side device itself needs to adopt.

[0088] In one embodiment, the terminal may send indication information to the network-side device, and based on the indication information, the network-side device may determine the duplex mode of the terminal.

[0089] In one embodiment, the duplex mode includes at least a half-duplex mode and a full-duplex mode. The full-duplex mode refers to performing uplink transmission and downlink transmission simultaneously in the same frequency domain resources.

[0090] For example, for network-side devices, full-duplex mode means that uplink transmission and downlink reception are performed simultaneously in the same frequency domain resources, such as the same time slot. The uplink transmission and downlink reception can be performed for different terminals or for the same terminal.

[0091] For example, for a terminal, full-duplex mode refers to simultaneous uplink transmission and downlink reception in the same frequency domain resource, such as the same time slot, where the time slot includes at least one of the following: a downlink slot in the time division duplexing (TDD) frequency band, an uplink slot in the TDD frequency band, and a slot in the frequency division duplexing (FDD) frequency band.

[0092] In addition, for network-side devices, full-duplex modes can include subband-based full-duplex (SBFD) and shared spectrum full-duplex (SSFD). SBFD can be further divided into two full-duplex modes: non-overlapping subband and partial overlapping subband.

[0093] In one embodiment, based on the indication information sent by the terminal, the network side device can determine the duplex mode supported by the terminal, for example, it can be determined that the terminal only supports half-duplex mode, or only supports full-duplex mode, or supports both half-duplex mode and full-duplex mode.

[0094] Based on this, the network side device can determine which duplex mode the terminal can be scheduled to adopt in the future.

[0095] In one embodiment, based on the indication information sent by the terminal, the network side device can determine the duplex mode that the terminal expects the network side device to schedule the terminal to adopt. For example, when the terminal supports both half-duplex mode and full-duplex mode, the duplex mode that the terminal expects the network side device to schedule the terminal to adopt may be only half-duplex mode, or only full-duplex mode, or both full-duplex mode and half-duplex mode.

[0096] Based on this, the network side device can determine which duplex mode the terminal needs to adopt in the subsequent scheduling.

[0097] The duplex mode supported by the terminal includes the duplex mode that the terminal expects the network side device to schedule the terminal to adopt, that is, the terminal does not expect the network side device to schedule the terminal to adopt a duplex mode that the terminal does not support.

[0098] In one embodiment, based on the indication information sent by the terminal, the network side device can determine the duplex mode that the terminal expects the network side device to adopt, for example, the terminal expects the network side to adopt full-duplex mode, or half-duplex mode, or both full-duplex mode and half-duplex mode.

[0099] Based on this, the network side device can determine which duplex mode it needs to adopt subsequently. Of course, the duplex mode actually adopted by the subsequent network side device may be different from the duplex mode that the terminal expects the network side device to adopt. The specific duplex mode can be determined by the network side device according to needs. However, when both full-duplex mode and half-duplex mode are available, the duplex mode that the terminal expects the network side device to adopt can be preferentially adopted to meet the needs of the terminal.

[0100] In one embodiment, in addition to determining the duplex mode information of the terminal based on the indication information sent by the terminal, the network side device can also determine the duplex mode information of the terminal based on the CSI reported by the terminal, determine the duplex mode information of the terminal based on the power parameters configured for the terminal, and determine the duplex mode information of the terminal based on interference-related information.

[0101] In one embodiment, the CSI reported by the terminal to the network side device can be obtained based on a reference signal RS (Reference Signal), wherein the RS can be an existing RS, including but not limited to Aperiodic CSI RS, Periodic CSI RS, semi-persistent CSI RS, or a dedicated CSI RS, such as a CSI RS dedicated to determining the duplex mode information of the terminal. The dedicated CSI RS can be periodic, non-periodic, semi-persistent, or based on a subband or bandwidth.

[0102] The network-side device can determine the current channel quality based on the CSI reported by the terminal. If the current channel quality is relatively poor, the terminal can be scheduled to use half-duplex mode; if the current channel quality is relatively good, the terminal can be scheduled to use full-duplex mode.

[0103] In one embodiment, the network side device can configure power parameters for the terminal, including but not limited to the initial power P0, dynamic power adjustment parameters, etc. P0 can be adjusted through the dynamic power adjustment parameters. The network side can determine the current transmission power of the terminal based on P and the dynamic power adjustment parameters.

[0104] Since cross-slot interference is more serious when the transmission power is high, the communication effect of full-duplex mode is poor. Therefore, when the network side equipment determines that the transmission power of the terminal is relatively high according to the power parameters, it can determine that the duplex mode adopted by the scheduling terminal is half-duplex mode, so as to avoid strong cross-slot interference and ensure good communication quality; when the transmission power of the terminal is determined to be relatively low according to the power parameters, it can determine that the duplex mode adopted by the scheduling terminal is full-duplex mode, so as to improve communication efficiency under the condition of weak cross-slot interference.

[0105] In one embodiment, the interference-related information includes at least one of the following:

[0106] The transmission power of the network side device;

[0107] Antenna configuration of the network side device;

[0108] Interference measurement information.

[0109] In one embodiment, the network side device can determine the network interference situation based on the interference-related information. When the network interference is relatively weak, it can be determined that the duplex mode adopted by the scheduling terminal is full-duplex mode, or it can be determined that the duplex mode that the network side device itself needs to adopt is full-duplex mode; when the network interference is relatively strong, it can be determined that the duplex mode adopted by the scheduling terminal is half-duplex mode, or it can be determined that the duplex mode that the network side device itself needs to adopt is half-duplex mode.

[0110] In one embodiment, the network-side device can determine the interference to other network-side devices based on its own transmission power. For example, when the transmission power of the network-side device is relatively low (for example, lower than a preset power threshold), it can be determined that the interference caused by the downlink transmission of the network-side device to the uplink connection of other network-side devices is within a controllable range, and then it can be determined that the duplex mode adopted by the network-side device itself is full-duplex mode; for example, when the transmission power of the network-side device is relatively high (for example, higher than a preset power threshold), it can be determined that the interference caused by the downlink transmission of the network-side device to the uplink connection of other network-side devices is uncontrollable, and then it can be determined that the duplex mode adopted by the network-side device itself is half-duplex mode.

[0111] In one embodiment, the network side device can determine the self-interference isolation based on its own antenna configuration. For example, if the antenna configuration has a relatively large number of available antennas (for example, greater than a preset number threshold), it can be determined that the self-interference isolation is high and the ability to suppress self-interference is strong. Therefore, it can be determined that the duplex mode adopted by the network side device itself is full-duplex mode; for example, if the antenna configuration has a relatively small number of available antennas (for example, less than a preset number threshold), it can be determined that the self-interference isolation is low and the ability to suppress self-interference is weak. Therefore, it can be determined that the duplex mode adopted by the network side device itself is half-duplex mode.

[0112] In one embodiment, the network side device can also obtain interference measurement information, such as the CSI reported by the terminal. When it is determined based on the interference measurement information that the interference in the current network is relatively small, it can be determined that the duplex mode adopted by the network side device itself is full-duplex mode; when it is determined based on the interference measurement information that the interference in the current network is relatively large, it can be determined that the duplex mode adopted by the network side device itself is half-duplex mode.

[0113] It should be noted that the duplex mode adopted by the scheduling terminal determined by the network side device may or may not be associated with the duplex mode adopted by the network side device itself determined by the network side device, and can be set as needed.

[0114] For example, the network-side device can separately determine the duplex mode used by the dispatch terminal and the duplex mode used by the network itself, and there is no correlation between the duplex modes used by the two;

[0115] For example, the network side device can determine the duplex mode adopted by the network side device itself according to the duplex mode adopted by the dispatching terminal. For example, if it is determined that the dispatching terminal adopts the full-duplex mode, it can be determined that the network side device adopts the full-duplex mode, or it can be determined that the network side device adopts the half-duplex mode.

[0116] For example, the network side device can determine the duplex mode adopted by the scheduling terminal based on the duplex mode adopted by the network side device itself. For example, if it is determined that the network side device adopts the full-duplex mode, it can be determined that the duplex mode adopted by the scheduling terminal is the full-duplex mode, or it can be determined that the duplex mode adopted by the scheduling terminal is the half-duplex mode.

[0117] According to the embodiments of the present disclosure, the network-side device can determine the terminal's duplex mode information, the duplex mode used by the network-side device itself, and other information based on the indication information sent by the terminal, the reported CSI, the power parameters configured for the terminal, interference-related information, etc. Thus, the network-side device can learn the terminal's duplex mode information and determine the duplex mode used by the network-side device itself. It can then subsequently schedule the terminal to adopt an appropriate duplex mode based on actual conditions, and adopt an appropriate duplex mode itself, thereby avoiding problems caused by the duplex mode used by the terminal or the network-side device not matching the actual conditions.

[0118] In one embodiment, if the network side device does not determine whether the terminal supports full-duplex mode, then when scheduling the duplex mode adopted by the terminal, the terminal is only scheduled to adopt half-duplex mode. For example, for a certain time slot, the terminal will only be scheduled to perform uplink transmission or downlink reception on the time slot, so as to avoid scheduling the terminal to adopt full-duplex mode when the terminal does not support full-duplex and causing communication problems.

[0119] In one embodiment, the duplex mode information of the terminal includes a duplex mode supported by the terminal, and the indication information includes at least one of the following:

[0120] Type information of the terminal, wherein the type information is associated with whether the terminal supports full-duplex mode;

[0121] The capability information of the terminal, wherein the capability information is used to indicate a duplex mode supported by the terminal.

[0122] In one embodiment, the terminal may report its own type information to the network side device. The network side device may pre-store the association between the terminal type information and whether the terminal supports full-duplex mode, and then determine whether the terminal supports full-duplex mode based on the terminal type information.

[0123] For example, type A is associated with the terminal supporting full-duplex mode, and type B is associated with the terminal not supporting full-duplex mode. When the indication information received by the network side device is type A, it can be determined that the terminal supports full-duplex mode. When the indication information received is type B, it can be determined that the terminal does not support full-duplex mode.

[0124] Based on this approach, the terminal can implicitly indicate to the network-side device whether the terminal supports the full-duplex mode by reporting the terminal type information to the network-side device.

[0125] In one embodiment, the terminal can explicitly indicate to the network device the duplex modes it supports. For example, the capability information may indicate that the terminal only supports half-duplex mode, or only supports full-duplex mode, or supports both half-duplex mode and full-duplex mode. In addition to this indication method, the terminal may default to supporting half-duplex mode, and the capability information may indicate whether the terminal supports full-duplex mode based on this.

Figure 8 As shown, the duplex mode information of the terminal includes the duplex mode that the network side device is expected to schedule the terminal to adopt, and the method further includes:

[0127] In step S801, the indication information is received during a random access procedure.

[0128] In one embodiment, the terminal can send the indicated indication information to the network side device on appropriate resources as needed. For example, the indication information can be sent to the network side device during the random access process. Accordingly, it can be ensured that during the random access process, the network side device can determine the duplex mode information of the terminal so that after the communication connection is subsequently established, the terminal can be scheduled to adopt the appropriate duplex mode as soon as possible, or the duplex mode expected by the terminal can be adopted as soon as possible.

Figure 9 As shown, the indication information includes a preamble code of random access, and determining the duplex mode information of the terminal according to the indication information includes:

[0130] In step S901, according to the association relationship between the preamble and the duplex mode scheduled to be adopted by the terminal, it is determined that the duplex mode corresponding to the preamble is the duplex mode scheduled to be adopted by the terminal.

[0131] In one embodiment, the terminal and the network-side device may pre-store a first association between a preamble (for example, a preamble index) and a duplex mode desired by the terminal. After determining the duplex mode desired by the terminal, the preamble corresponding to the duplex mode desired by the terminal may be determined based on the first association, and the determined preamble may be sent to the network-side device. After receiving the preamble sent by the terminal, the network-side device may determine the duplex mode desired by the terminal corresponding to the preamble based on the first association.

[0132] Figure 10 FIG. 1 is a schematic flow chart of another method for determining a working mode according to an embodiment of the present disclosure. Figure 10As shown, determining the duplex mode information of the terminal according to the indication information includes:

[0134] In step S1002, according to the association relationship between the random access opportunity and the duplex mode scheduled to be adopted by the terminal, it is determined that the duplex mode corresponding to the specific random access opportunity is the duplex mode scheduled to be adopted by the terminal.

[0135] In one embodiment, the terminal and the network-side device may pre-store a second association between a random access opportunity and a duplex mode desired by the terminal. After determining the duplex mode desired by the terminal, the terminal and the network-side device may determine a specific random access opportunity corresponding to the duplex mode desired by the terminal based on the second association, and then send indication information, such as a random access message, to the network-side device at the specific random access opportunity as the indication information. Upon receiving the random access message sent by the terminal at the specific random access opportunity, the network-side device may determine the duplex mode desired by the terminal corresponding to the specific random access opportunity based on the second association.

[0136] In one embodiment, determining the duplex mode information of the terminal according to the indication information includes:

[0137] Acquire the indication information from the random access message Msg3 or MsgA sent by the terminal;

[0138] Determine that the duplex mode indicated by the indication information is the duplex mode to be used by the scheduled terminal.

[0139] During the four-step random access process, the terminal may carry indication information in the random access message Msg3 and send it to the network side device; during the two-step random access process, the terminal may carry indication information in the random access message MsgA and send it to the network side device.
