Description

Scheduling method, device, equipment and readable storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a scheduling method, apparatus, device, and readable storage medium.

Background

Full-duplex terminals are a technical means for improving spectrum utilization and network throughput. By full duplex terminal is meant that the terminal communication allows data to be transmitted simultaneously in both directions, which corresponds in capability to a combination of two simplex communication modes.

Because the full-duplex base station and the terminal have technical problems of mutual interference, self-interference, coverage and the like, the product realization and the standard research of the full-duplex terminal are not developed in the current standards and industries. Compared with a half-duplex network, the full-duplex network also needs to consider the problems of coverage shrinkage and the like caused by coexistence of interference and deterioration of sensitivity between terminals in full duplex, between full-duplex terminals/full-duplex base stations, and between the full-duplex terminals and the conventional terminals or base stations.

Therefore, how to avoid the above interference of the full-duplex terminal is a main direction of research at present.

Detailed Description

In the embodiment of the present application, the term "and/or" describes an association relationship of associated objects, and means that there may be three relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, fig. 1 is a flowchart of a scheduling method provided in an embodiment of the present application, which is executed by a terminal, and as shown in fig. 1, the scheduling method includes the following steps:

step 101, sending capability indication information to a network device, wherein the capability indication information is used for indicating that a terminal supports full-duplex working capability.

In the embodiment of the application, the terminal may report the capability indication information to the network device actively, or may report the capability indication information to the network device in response to the indication of the network device. The initial operating mode of the terminal may be a half-duplex operating mode or a full-duplex operating mode.

If reporting is performed in response to the indication from the network device, before step 101, the method may further include: and receiving a fifth instruction of the network device, where the fifth instruction is used to instruct the terminal to report the capability indication information. Then, step 101 specifically is to send capability indication information to the network device according to the fifth indication.

Wherein the capability indication information includes one or more of:

the first frequency band supports full duplex capability (per band);

the first frequency range supports full duplex capability (per frequency range);

the first frequency band combination supports full-duplex capability (per band combination);

the terminal supports full duplex capability (per UE);

the terminal supports self-interference cancellation capability (band) in the second frequency band;

the terminal supports self-interference elimination capability in a second frequency range (per frequency range);

the terminal supports self-interference elimination capability in a second frequency band combination (per band combination);

the terminal supports interference cancellation capability (per UE).

The first frequency band or the second frequency band can be set according to actual needs, and can be one or more; the first frequency range or the second frequency range can be set according to actual needs, and can be one or more; the first frequency band combination or the second frequency band combination can be set according to actual needs, and can be one or more.

The self-interference cancellation capability may be measured by a self-interference cancellation amount, or may be measured by a sensitivity optimization value in each frequency band, each frequency range, or in some bandwidths.

For example, after the terminal completes random access, the reported capability indication information includes whether the terminal supports full duplex capability and a self-interference cancellation amount corresponding to the current transmission power. For example, as shown in table 1, the terminal stores the self-interference cancellation amount corresponding to different self-interference signal strengths in advance. And the terminal judges the self-interference elimination amount according to the current self-interference signal intensity and reports the self-interference elimination amount to the network equipment.

TABLE 1

For another example, after the terminal completes random access, the reported capability indication information includes whether the terminal supports full duplex capability and sensitivity optimization values corresponding to different bandwidths on the service frequency band. Assuming that the current service frequency band is n41, and combining table 2, the terminal reports the sensitivity optimization value in the corresponding bandwidth.

TABLE 2

Optionally, if the terminal supports half-duplex function capability, the terminal may further indicate that the terminal supports half-duplex operation capability in the capability indication information.

And 102, when the terminal works in a full-duplex mode, adjusting the working mode to a half-duplex mode or adjusting the current working time-frequency position.

Specifically, in this step, the terminal receives a first indication sent by the network device in response to the capability indication information, where the first indication is used to indicate that the operating mode of the terminal is a full duplex mode. And when the mobile terminal works in a full-duplex mode according to the first indication, if a preset requirement is met, the working mode is adjusted to be a half-duplex mode or the current working time-frequency position is adjusted.

In this step, the first indication may be received in at least two ways:

in the first mode, the terminal receives a full duplex mode indication signaling sent by the network device, where the full duplex mode indication signaling is used to indicate that the working mode of the terminal is a full duplex mode.

The signaling may be one or more of RRC (Radio Resource Control), MAC (Medium Access Control), and DCI (Downlink Control Information) signaling. The effective time of the signaling may be that the terminal takes effect immediately after receiving the signaling, or that the terminal takes effect after receiving the signaling for a period of time, or that the terminal takes effect at the next uplink transmission time after receiving the information of the network device. If the terminal is already in full duplex mode before receiving the signaling, the signaling is ignored. Wherein the signaling may be periodic signaling.

In practical application, considering that the full-duplex self-interference suppression capability of the terminal is limited, the terminal is defaulted to work in a half-duplex working mode, and the network equipment determines whether to schedule the terminal to enter the full-duplex mode according to the downlink channel quality of the terminal.

And in the second mode, the terminal receives the first indication sent by the network equipment in an implicit mode, and sends and receives signals.

For example, the terminal may be scheduled to transmit and receive simultaneously by indicating through one or more of RRC, MAC, DCI signaling. That is, after receiving the signaling, the terminal can determine that the first indication needs to be reported, and simultaneously transmit and receive the signal. The effective time of the signaling may be that the terminal takes effect immediately after receiving the signaling, or that the terminal takes effect after receiving the signaling for a period of time, or that the terminal takes effect at the next uplink transmission time after receiving the information of the network device.

The terminal operating in the full-duplex mode needs to support radio frequency index requirements such as sensitivity in the full-duplex mode.

The preset requirement may be, for example, that the terminal detects that the signal quality of the received signal does not meet the requirement, or that the terminal receives an indication that the network device adjusts the operating mode to the half-duplex mode or adjusts the currently operating time-frequency position in response to a request from the terminal, or that the terminal receives an indication that the network device indicates the terminal, and adjusts the operating mode to the half-duplex mode or adjusts the currently operating time-frequency position, or that the terminal autonomously decides to return to the half-duplex mode, or that the terminal sensitivity deteriorates to a certain degree (for example, x dB unit) or is lower than a certain threshold.

When operating in the full-duplex mode, the terminal detects the signal quality of the received signal, such as CQI (Channel quality indicator), SINR (signal-to-noise and interference ratio), and so on. The preset requirement may be set as needed, for example, whether the preset requirement is greater than (or less than) a threshold for setting the CQI, whether the preset requirement is greater than (or less than) a threshold for setting the SINR, and the like. For example, if the CQI of the currently received signal is less than a set threshold, the signal quality may be considered unsatisfactory. At this time, the adjustment of the working mode to the half-duplex mode or the adjustment of the current working time-frequency position can be triggered.

In this step, the terminal may adjust the working mode to the half-duplex mode or adjust the current working time-frequency position by at least three ways.

In a first mode, the terminal reports signal quality information of a currently received signal to the network device, so as to indicate the current signal quality, receives a second indication sent by the network device in response to the signal quality information, and then adjusts a working mode to a half-duplex mode or adjusts a currently working time-frequency position according to the second indication. That is, the network device determines whether to schedule the terminal to back to the half-duplex operating mode according to the signal quality information.

In a second mode, the terminal sends a first request to the network device, where the first request is used to indicate that the operation mode is required to be adjusted to the half-duplex mode, and receives a third indication sent by the network device in response to the first request. And then, adjusting the working mode to be a half-duplex mode or adjusting the current working time-frequency position according to the third indication. Wherein the first request comprises: information of half Duplex mode (TDD (Time Division Duplex) or FDD (Frequency Division Duplex)), time stamp. The timestamp may be an operation mode adjustment time, a signal degradation time, or the like.

And in a third mode, the terminal sends a fourth instruction to the network equipment, wherein the fourth instruction is used for indicating that the terminal autonomously adjusts the working mode to the half-duplex mode. The fourth indication comprises: information of half duplex mode (TDD or FDD), time stamp. The time stamp may be an operation mode adjustment time, a signal degradation time, or the like.

In this way, the terminal can autonomously fallback to the half-duplex mode according to the conditions of the quality of the received signaling, the sensitivity fallback threshold value and the like, and report the signaling with the changed working mode to the network equipment. Wherein, the signaling may include: half duplex operating mode (TDD or FDD), time stamping. The timestamp may be an operation mode adjustment time, a signal degradation time, or the like.

In order to ensure the integrity of data, when operating in half-duplex mode, the terminal may also receive data lost in full-duplex mode retransmitted by the network device. For example, if there is data loss within the timestamp (after full duplex is changed to half duplex mode), the network device may send the data down again in half duplex mode according to the timestamp information.

Through the modes, the terminal can report the information to the network equipment flexibly, so that the network equipment can make further judgment or indication conveniently.

In the embodiment of the application, the network device schedules the terminal to work in a full-duplex mode according to the capability indication information reported by the terminal, and when the terminal works in the full-duplex mode, if the preset requirement is met, the working mode is adjusted to a half-duplex mode or the current working time-frequency position is adjusted. By the method, the advantages of the full-duplex terminal can be exerted, and meanwhile, the scheduling of the full-duplex working mode is realized, so that the interference between the full-duplex terminal and other terminals or network equipment is reduced.

Referring to fig. 2, fig. 2 is a flowchart of a scheduling method provided in an embodiment of the present application, and the scheduling method is executed by a network device. The network device may be, for example, a base station. As shown in fig. 2, the method comprises the following steps:

step 201, receiving capability indication information sent by a terminal, where the capability indication information is used to indicate that the terminal supports full-duplex working capability.

In this step, the network device may receive capability indication information actively reported by the terminal. Or, the network device may further instruct the terminal to report the capability indication information, and receive the capability indication information reported by the network device in response to the instruction. Wherein the meaning of the capability indication information is the same as that described in the previous embodiment.

Step 202, when the terminal works in a full-duplex mode, the working mode of the terminal is adjusted to a half-duplex mode or the current working time-frequency position is adjusted.

Specifically, in this step, the network device may send, in response to the capability indication information, a first indication to the terminal, where the first indication is used to indicate that the operation mode of the terminal is a full duplex mode. And then, the network equipment adjusts the working mode of the terminal into a half-duplex mode or adjusts the current working time-frequency position according to the information sent by the terminal.

In this step, the network device may send the first indication to the terminal by at least two ways:

in the first mode, the network device sends a full duplex mode indication signaling to the terminal, where the full duplex mode indication signaling is used to indicate that the working mode of the terminal is a full duplex mode.

The signaling may be one or more of RRC, MAC, DCI signaling. The effective time of the signaling may be that the terminal takes effect immediately after receiving the signaling, or that the terminal takes effect after receiving the signaling for a period of time, or that the terminal takes effect at the next uplink transmission time after receiving the information of the network device. If the terminal is already in full duplex mode before receiving the signaling, the signaling is ignored. The signaling may be periodic signaling.

And in the second mode, the network equipment sends a first indication to the terminal in an implicit mode and schedules the terminal to send and receive signals.

For example, the network device may implicitly indicate that the terminal is operating in full duplex mode. The indication may be one or more of RRC, MAC, DCI signaling, scheduling the terminal to transmit and receive simultaneously. The signaling validation time may be the time when the terminal receives the signaling and then takes effect immediately, may also take effect after receiving the signaling for a period of time, and may also take effect at the next uplink transmission time after receiving the information of the network device.

According to the difference of the received information sent by the terminal, the network equipment can adjust the working mode of the terminal to a half-duplex mode or adjust the current working time-frequency position by different modes.

In the first mode, the network device receives the signal quality information of the current received signal reported by the terminal. And if the working mode of the terminal needs to be adjusted is determined according to the signal quality information, sending a second instruction to the terminal, wherein the second instruction is used for instructing the terminal to adjust the working mode to a half-duplex mode or adjust the current working time-frequency position.

Wherein the second indication comprises one or more of: information of half-duplex mode, working mode change trigger condition, working mode change trigger time, and duration of the changed working mode.

If the network equipment acquires the signal quality information of the terminal but does not acquire the working mode conversion information of the terminal, the network equipment determines whether to change the working mode of the terminal or avoid interference by scheduling the terminal to different time-frequency positions in a scheduling mode according to the deterioration condition of the signal of the terminal. In addition, the network device may instruct the terminal to change the operation mode, where the instruction information includes one or more of the following information: the working mode (TDD or FDD) after the terminal change, the triggering condition for the terminal working mode change, and the time point and the duration for the terminal working mode change.

And in a second mode, the network equipment receives a first request sent by the terminal, wherein the first request is used for indicating that the working mode is required to be adjusted to the half-duplex mode. And if the working mode of the terminal needs to be adjusted, sending a third instruction to the terminal, wherein the third instruction is used for instructing the terminal to adjust the working mode to a half-duplex mode or adjust the current working time-frequency position.

Wherein the first request comprises: information of half duplex mode, timestamp. The third indication comprises one or more of: information of half-duplex mode, working mode change trigger condition, working mode change trigger time, and duration of the changed working mode.

In a specific application, if the network device obtains a signaling request initiated by the terminal and returning to a half-duplex mode, and obtains the working mode conversion information of the terminal, the network device determines whether to change the working mode of the terminal or avoid interference by scheduling the terminal to different time-frequency positions in a scheduling manner, and can also instruct the terminal to change the working mode. Wherein the indication information includes one or more of the following: the working mode (TDD or FDD) after the terminal change, the triggering condition for the terminal working mode change, and the time point and the duration for the terminal working mode change.

And in a third mode, the network equipment receives a fourth instruction sent by the terminal, wherein the fourth instruction is used for indicating that the terminal autonomously adjusts the working mode to the half-duplex mode. Wherein the fourth indication comprises: information of half duplex mode, timestamp.

In this case, in order to ensure the integrity of the data acquired by the terminal, the network device retransmits, in the half-duplex mode, the data lost in the full-duplex mode to the terminal.

Specifically, if the network device obtains the information that the terminal has autonomously returned to the half-duplex mode, the network device schedules the terminal working mode according to the current working mode information reported by the terminal. If data is lost in the timestamp (which can be the working mode adjustment time, the signal deterioration time, etc.), the network device can perform rescheduling transmission on the data which is not successfully demodulated when the terminal works in the full-duplex mode.

Referring to fig. 3, fig. 3 is a flowchart of a scheduling method provided in an embodiment of the present application. As shown in fig. 3, the method comprises the following steps:

step 301, the base station requests the terminal with full duplex capability to report the full duplex capability.

This step is an optional step.

Step 302, the terminal reports the signaling supporting the full duplex working capability.

Wherein the signaling comprises one or more of:

the first frequency band supports full duplex capability (per band);

the first frequency band combination supports full duplex capability (per band combination);

the terminal supports full duplex capability (per UE);

the terminal supports self-interference cancellation capability (per band) in the second frequency band;

the terminal supports self-interference elimination capability in a second frequency band range (per frequency range);

the terminal supports interference cancellation capability (per UE).

The first frequency band and the second frequency band can be set according to actual needs.

Step 303, the base station indicates the terminal to work in full duplex mode.

And step 304, the terminal works in a full duplex mode according to the indication.

Step 305, the terminal detects the quality of the received signal and processes the signal according to the following mode:

(1) And reporting the quality information of the current receiving signal, wherein the information comprises the quality of the current receiving signal, such as CQI and SINR. And the base station determines whether the scheduling terminal backs to a half-duplex working mode or not according to the signal quality information.

(2) The full-duplex terminal initiates a signaling request for returning to a half-duplex terminal mode, and initiates a signaling for changing the working mode to the base station. The signaling may include a half duplex operating mode (TDD or FDD), a timestamp (which may be an operating mode adjustment time, a signal degradation time, etc.).

(3) The full-duplex terminal can autonomously back to a half-duplex terminal according to the conditions of the quality of the received signaling, the sensitivity back-off threshold value and the like, and simultaneously report the signaling with the changed working mode to the base station. The signaling may include a half duplex operating mode (TDD or FDD), a timestamp (which may be an operating mode adjustment time, a signal degradation time, etc.). If data is lost in the timestamp (after full duplex is changed into half duplex mode), the network can send the data again in half duplex mode according to the timestamp information.

For example, when a terminal operating in the full-duplex mode is at a cell edge or is subjected to strong interference, which causes sensitivity deterioration or deterioration in received signal quality or failure to correctly demodulate a signal or deterioration in demodulation performance, the terminal falls back from the full-duplex mode to the half-duplex mode. And at the moment, the half-duplex terminal meets radio frequency indexes such as sensitivity and the like of the half-duplex terminal, records a working mode adjustment timestamp and a signal deterioration timestamp, and reports the timestamp and the half-duplex working mode to the base station at the next uplink moment.

Step 306, the base station receives the information reported by the full duplex terminal, and processes the information according to the following mode:

(1) If the base station acquires the terminal signal deterioration information but does not acquire the terminal working mode conversion information, the base station determines whether to change the terminal working mode or avoid interference by scheduling the terminal to different time-frequency positions according to the terminal signal deterioration condition, and can also instruct the terminal to change the working mode. The indication includes one or more of: the working mode (TDD or FDD) after the terminal is changed, the triggering condition for changing the working mode of the terminal, and the time point and the duration for changing the working mode of the terminal.

(2) If the obtaining terminal initiates a signaling request for returning to a half-duplex mode, the base station obtains the conversion information of the working mode of the terminal, and whether the working mode of the terminal is changed or whether the interference is avoided by scheduling the terminal to different time-frequency positions through a scheduling mode, and the base station can also instruct the terminal to change the working mode. The indication includes one or more of: the working mode (TDD or FDD) after the terminal change, the triggering condition for the terminal working mode change, and the time point and the duration for the terminal working mode change.

(3) And if the information that the terminal automatically returns to the half-duplex terminal is obtained, the base station schedules the working mode of the terminal according to the current working mode information reported by the terminal. If data is lost in the time stamp (the time stamp can be the working mode adjustment time, the signal deterioration time and the like), the base station can perform rescheduling transmission on the data which is not successfully demodulated in the full duplex mode

And if the terminal receives the working mode changing information, changing the working mode at the corresponding effective time.
