DETAILED DESCRIPTION

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those of ordinary skill in the art without any creative efforts will fall within the scope of protection of this disclosure.

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

It should be understood that although the terms “first,” “second,” and “third,” etc. may be used to describe various information in the embodiments of this disclosure, the information should not be limited by 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 this 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 . . . ”

For the purpose of brevity and ease of understanding, the terms used herein to characterize size relationships are “greater than” or “less than”, “higher than” or “lower than”. However, it can be understood by those skilled in the art that the term “greater than” also covers the meaning of “greater than or equal to”, and “less than” also covers the meaning of “less than or equal to”, the term “higher than” covers the meaning of “higher than or equal to”, and “lower than” also covers the meaning of “lower than or equal to”.

For example, for a base station, the communication based on the full-duplex mode can easily interfere with the uplink transmission of other base stations. For example, for a terminal, the communication based on the full-duplex mode can hardly ensure good communication quality if the terminal has poor self-interference suppression capability.

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

FIG. 1 is a schematic flowchart of a method for indicating a working mode according to an embodiment of the present disclosure. The method for indicating the working mode shown in this embodiment may be performed by a terminal, which includes but is not limited to a mobile phone, a tablet computer, a wearable device, a sensor, an Internet of Things device and other communication devices. The terminal can communicate with a network side device, which includes but is not limited to a network side device in 4G, 5G, 6G, or other communication systems, such as a base station, a core network, etc.

As shown in FIG. 1, the method for indicating the working mode may include the following step:

- S101, sending indication information to a network side device for indicating duplex mode information of the terminal to the network side device.

In one embodiment, the terminal may send indication information to the network side device. The network side device may determine the duplex mode of the terminal based on the indication information.

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

- a duplex mode supported by the terminal;
- a duplex mode expected to be adopted for scheduling the terminal by the network side device; or
- a duplex mode expected to be adopted by the network side device.

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 resource(s).

For example, for a network side device, the full-duplex mode means that uplink reception and downlink transmission are performed simultaneously in the same frequency domain resource(s), such as the same slot, wherein the uplink reception and downlink transmission can be performed for different terminals or for the same terminal.

For example, for a terminal, the full-duplex mode means that uplink transmission and downlink reception are performed simultaneously in the same frequency domain resource(s), such as the same slot, wherein the slot includes at least one of the following: a downlink slot in a Time Division Duplexing (TDD) frequency band, an uplink slot in a TDD frequency band, or a slot in a Frequency Division Duplexing (FDD) frequency band.

In addition, for a network side device, the full-duplex mode may include Subband-Based Full Duplex (SBFD) and Shared Spectrum Full Duplex (SSFD). SBFD can be further divided into two full-duplex modes, i.e., Non-overlapping subband and Partial overlapping subband.

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 the half-duplex mode, or only supports the full-duplex mode, or supports both the half-duplex mode and the full-duplex mode.

Based on this, the network side device can determine which duplex mode can be adopted subsequently for scheduling the terminal.

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

Based on this, the network side device can determine which duplex mode needs to be adopted subsequently for scheduling the terminal.

The duplex mode supported by the terminal includes a duplex mode expected to be adopted for scheduling the terminal by the network side device, 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.

In one embodiment, based on the indication information sent by the terminal, the network side device can determine the duplex mode excepted by the terminal to be adopted by the network side device, for example, the terminal expects the network side to adopt the full-duplex mode, or the half-duplex mode, or either the full-duplex mode or the half-duplex mode.

Based on this, the network side device can determine which duplex mode it needs to adopt subsequently. Of course, the actual duplex mode adopted by the network side device subsequently 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 either the full-duplex mode or the half-duplex mode can be adopted, the duplex mode that the terminal expects the network side device to adopt can be preferentially adopted to meet the needs of the terminal.

According to the embodiments 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 to subsequently schedule the terminal to adopt an appropriate duplex mode according to actual situations, thereby avoiding problems caused by the duplex mode adopted by the terminal not matching the actual situations.

In one embodiment, if the network side device does not determine whether the terminal supports the full-duplex mode, the network device may only schedule the terminal to adopt the half-duplex mode when scheduling the terminal to adopt a duplex mode. For example, for a certain time slot, the network device may only schedule the terminal to perform uplink transmission on that time slot, or downlink reception on that time slot, in order to avoid communication problems caused by scheduling the terminal to adopt the full-duplex mode when the terminal does not support full-duplex mode.

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 through several embodiments.

FIG. 2 is a schematic flowchart of another method for indicating a working mode according to an embodiment of the present disclosure. As shown in FIG. 2, the duplex mode information of the terminal includes the duplex mode supported by the terminal, and sending the indication information to the network side device includes the following step:

- S201, sending type information of the terminal to the network side device, wherein the type information is associated with whether the terminal supports a full-duplex mode.

In one embodiment, the terminal may report its own type information to the network side device, wherein the network side device may pre-store the association relationship(s) between the terminal's type information and whether the terminal supports the full-duplex mode. Then, it can be determined whether the terminal supports the full-duplex mode according to the terminal's type information.

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

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 type information of the terminal to the network side device.

FIG. 3 is a schematic flowchart of yet another method for indicating a working mode according to an embodiment of the present disclosure. As shown in FIG. 3, the duplex mode information of the terminal includes the duplex mode supported by the terminal, and sending the indication information to the network side device includes the following step:

- S301, sending capability information of the terminal to the network side device, wherein the capability information of the terminal is used to indicate the duplex mode supported by the terminal.

In one embodiment, the terminal can explicitly indicate to the network side device the duplex mode supported by the terminal. For example, the capability information can be that the terminal only supports the half-duplex mode, or the terminal only supports the full-duplex mode, or the terminal supports both the half-duplex mode and the full-duplex mode. In addition to this indication method, the terminal can be defaulted to support the half-duplex mode, and on this basis, the capability information indicates whether the terminal supports the full-duplex mode or not.

FIG. 4 is a schematic flowchart of yet another method for indicating a working mode according to an embodiment of the present disclosure. As shown in FIG. 4, the duplex mode information of the terminal includes the duplex mode expected to be adopted for scheduling the terminal by the network side device, and sending the indication information to the network side device includes the following step:

- S401, sending the indication information to the network side device during a random access process.

In one embodiment, the terminal may send the indication information to the network side device on appropriate resources as needed. For example, the terminal may send the indication information to the network side device during the random access process. Accordingly, it can be ensured that the network side device can determine the duplex mode information of the terminal during the random access process, so that after the subsequent communication connection is 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.

FIG. 5 is a schematic flowchart of yet another method for indicating a working mode according to an embodiment of the present disclosure. As shown in FIG. 5, sending the indication information to the network side device during the random access process includes the following step:

- S501, sending a random access preamble to the network side device, wherein the preamble is associated with the duplex mode expected by the terminal.

In one embodiment, the terminal and the network side device may pre-store a first association relationship between a preamble (e.g., a preamble index) and a duplex mode expected by the terminal. After the duplex mode expected by the terminal is determined, the preamble corresponding to the duplex mode expected by the terminal can be determined according to the first association relationship, and then the determined preamble is sent to the network side device. After receiving the preamble sent by the terminal, the network side device can determine the duplex mode expected by the terminal corresponding to the preamble according to the first association relationship.

FIG. 6 is a schematic flowchart of yet another method for indicating a working mode according to an embodiment of the present disclosure. As shown in FIG. 6, sending the indication information to the network side device during the random access process includes the following step:

- S601, sending the indication information to the network side device at a specific random access occasion (RO), wherein the specific random access occasion is associated with the duplex mode expected by the terminal.

In one embodiment, the terminal and the network side device may pre-store a second association relationship between a random access occasion and a duplex mode expected by the terminal. After the duplex mode expected by the terminal is determined, the specific random access occasion corresponding to the duplex mode expected by the terminal can be determined according to the second association relationship, and then the indication information is sent to the network side device at the specific random access occasion. For example, a random access message serves as the indication information. The network side device receives the random access message sent by the terminal at the specific random access occasion, and can determine the duplex mode expected by the terminal corresponding to the specific random access occasion according to the second association relationship.

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 information associated with the duplex mode expected by the terminal.

During a 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 a 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.

FIG. 7 is a schematic flowchart of a method for determining a working mode according to an embodiment of the present disclosure. The method for determining the working mode shown in this embodiment may be performed by a network side device which includes but is not limited to a network side device in 4G, 5G, 6G and other communication systems, such as a base station, a core network, etc. The network side device can communicate with a terminal which includes but is not limited to a mobile phone, a tablet computer, a wearable device, a sensor, an Internet of Things device and other communication devices.

As shown in FIG. 7, the method for determining the working mode may include the following step:

- S701, determining duplex mode information of a terminal according to at least one of the following:
- indication information sent by the terminal;
- Channel State Information (CSI) sent by the terminal;
- a power parameter configured for the terminal; or
- interference-related information.

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

- a duplex mode supported by the terminal;
- a duplex mode expected by the terminal to be adopted for scheduling the terminal by the network side device; or
- a duplex mode expected by the terminal to be adopted by the network side device.

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.

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.

Based on this, the network side device can determine which duplex mode can be adopted subsequently for scheduling the terminal.

Based on this, the network side device can determine which duplex mode needs to be adopted subsequently for scheduling the terminal.

In one embodiment, based on the indication information sent by the terminal, the network side device can determine the duplex mode expected by the terminal to be adopted by the network side device, for example, the terminal expects the network side to adopt the full-duplex mode, or the half-duplex mode, or either the full-duplex mode or the half-duplex mode.

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, or based on the power parameter(s) configured for the terminal. The duplex mode information of the terminal can also be determined based on the interference-related information.

In one embodiment, the CSI reported by the terminal to the network side device can be obtained based on a Reference Signal (RS). The RS may be an existing RS, including but not limited to Aperiodic CSI RS, Periodic CSI RS, or semi-persistent CSI RS. The RS may also be a dedicated CSI RS, such as a CSI RS of the CSI dedicated to determining the duplex mode information of the terminal. The dedicated CSI RS can be periodic, aperiodic, semi-persistent, or based on subbands or bandwidths.

The network side device may 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 adopt the half-duplex mode.

In one embodiment, the network side device may configure the power parameter(s) for the terminal, including but not limited to an initial power P0, a dynamic power adjustment parameter, etc. P0 can be adjusted through the dynamic power adjustment parameter. The network side can determine the current transmission power of the terminal based on P0 and the dynamic power adjustment parameter.

When the transmission power is high, cross-slot interference becomes more serious and the communication effect in full-duplex mode is poor. In this case, the network side device can determine that the duplex mode that the terminal is scheduled to adopt is the half-duplex mode if it determines, based on the power parameter, that the transmission power of the terminal is relatively high, in order to avoid strong cross-slot interference and ensure good communication quality. If the network side device determines, based on the power parameter, that the transmission power of the terminal is relatively low, it can determine that the duplex mode that the terminal is scheduled to adopt is the full-duplex mode, in order to improve communication efficiency in the case of weak cross-slot interference.

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

- a transmission power of the network side device;
- an antenna configuration of the network side device; or
- interference measurement information.

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 that the terminal is scheduled to adopt is the full-duplex mode, and it can also be determined that the duplex mode that the network side device itself needs to adopt is the full-duplex mode. When the network interference is relatively strong, it can be determined that the duplex mode that the terminal is scheduled to adopt is the half-duplex mode, and it can also be determined that the duplex mode that the network side device itself needs to adopt is the half-duplex mode.

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 reception 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 reception 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.

In one embodiment, the network side device can determine the self-interference isolation degree according to 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 degree 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 degree 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.

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 that the interference in the current network is relatively small based on the interference measurement information, it can be determined that the duplex mode adopted by the network side device itself is full duplex mode. When it is determined that the interference in the current network is relatively large based on the interference measurement information, it can be determined that the duplex mode adopted by the network side device itself is half-duplex mode.

It should be noted that the duplex mode to be adopted by the scheduled terminal and determined by the network side device, may or may not be associated with the duplex mode adopted by the network side device itself and determined by the network side device, which can be set as desired.

For example, the network side device can separately determine the duplex mode to be adopted by the scheduled terminal and the duplex mode adopted by the network side itself. There is no correlation between the duplex modes adopted by the terminal and the network side device.

For example, the network side device can determine the duplex mode adopted by the network side device itself based on the duplex mode to be adopted by the scheduled terminal. For example, it is determined that the scheduled terminal adopts the full-duplex mode, and based on this, it can be determined that the network side device adopts the full-duplex mode, or the network side device adopts the half-duplex mode.

For example, the network side device can determine the duplex mode to be adopted by the scheduled terminal based on the duplex mode adopted by the network side device itself. For example, it is determined that the network side device adopts the full-duplex mode, and based on this, it can be determined that the duplex mode to be adopted by the scheduled terminal is the full-duplex mode, or the duplex mode to be adopted by the scheduled terminal is the half-duplex mode.

According to the embodiments of the present disclosure, the network side device can determine the information such as the duplex mode information of the terminal and the duplex mode adopted by the network side device itself, based on the indication information sent by the terminal, the reported CSI, the power parameter configured for the terminal, the interference-related information, etc. In this way, the network side device can know the duplex mode information of the terminal and determine the duplex mode adopted by the network side device itself. Subsequently, the network side device can schedule the terminal to adopt an appropriate duplex mode according to actual situations, and adopt an appropriate duplex mode itself, thereby avoiding problems caused by the duplex mode adopted by the terminal or the network side device not matching the actual situations.

In one embodiment, if the network side device does not determine whether the terminal supports full-duplex mode, the network side device only schedules the terminal to adopt the half-duplex mode when scheduling the terminal to adopt a duplex mode. For example, for a certain slot, the network device may only schedule the terminal to perform uplink transmission on that time slot, or downlink reception on that time slot, in order to avoid communication problems caused by scheduling the terminal to adopt the full-duplex mode when the terminal does not support full-duplex mode.

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

- type information of the terminal, wherein the type information is associated with whether the terminal supports a full-duplex mode; or
- capability information of the terminal, wherein the capability information is used to indicate the duplex mode supported by the terminal.

- S1002, determining, according to an association relationship between a random access occasion and a duplex mode expected by the terminal to be adopted for scheduling the terminal by the network side device, a duplex mode corresponding to the specific random access occasion as the duplex mode expected by the terminal to be adopted for scheduling the terminal by the network side device.

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