Please refer to FIG. 1. FIG. 1 is a structural diagram of a network system applicable to an embodiment of the present disclosure. As shown in FIG. 1, it includes a terminal 11 and a network device 12. The terminal 11 may be a user terminal (User Equipment, UE). ) Or other terminal side devices, such as: mobile phones, tablet computers (Tablet Personal Computer), laptop computers (Laptop Computer), personal digital assistants (personal digital assistant, PDA), mobile Internet devices (Mobile Internet Device, MID), For terminal-side devices such as wearable devices (Wearable Devices) or robots, it should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present disclosure.

In addition, the aforementioned network device 12 may be a master node (Master Node, MN) or a secondary node (Secondary Node, SN). It should be noted that, in the embodiments of the present disclosure, only a 5G base station is taken as an example, but the specific type of network equipment is not limited.

Please refer to FIG. 2. FIG. 2 is a flowchart of a mode switching method provided by an embodiment of the present disclosure. The method is applied to a terminal. As shown in FIG. 2, it includes the following steps:

Step 201: In the case of starting or restarting the first timer, enter the first mode, and the first timer is drx-InactivityTimer.

The above-mentioned starting or restarting of the first timer may be started or restarted when the terminal receives a PDCCH indicating new transmission (or called initial transmission) at the active time. It should be noted that, in the embodiment of the present disclosure, the condition for starting or restarting the first timer is not limited, for example, it may be a condition for starting or restarting drx-InactivityTimer newly defined in a subsequent protocol version.

The above-mentioned first mode may be referred to as the first working mode, in which the terminal monitors the PDCCH. For example: the first mode may be a mode configured with same slot scheduling, or the first mode may be a mode configured with a relatively large downlink or uplink multiple-input multiple-output (DL/UL MIMO layer), for example : Configure the downlink MIMO layer as a 4-layer mode, or configure the uplink MIMO layer as a 2-layer mode, etc.

Step 202: Start or restart a second timer, and switch from the first mode to the second mode when the second timer expires.

The foregoing second timer may be configured by the network side, for example, configured by the network side through RRC signaling, or the foregoing second timer may be a timer pre-appointed by the protocol. In addition, the foregoing second timer may be N slots, N mini-slots, N milliseconds, or N time domain symbols, where N is a positive integer. N is predefined by the network or configured by the network device.

In addition, starting or restarting the second timer may be a timer that is started or restarted after the above-mentioned first timer starts or restarts the first timer, but has not timed out, so that the first timer can be started or restarted. After the device, before the first timer expires, switch from the first mode to the second mode, thereby improving the transmission flexibility before the drx-InactivityTimer expires.

The length of the above-mentioned second timer may be less than the length of the first timer, so that the first mode can be switched to the second mode before the first timer expires, or the terminal can be switched from the first mode to the second mode before the first timer expires. It is possible to switch back and forth between the first mode and the second mode many times, so that the terminal can receive the PDCCH flexibly, and it is beneficial to the terminal to save energy.

Further, the first mode and the second mode may be two modes with different energy-saving effects. For example, the energy-saving effect of the first mode is lower than that of the second mode, so switching from the first mode to the second mode can be It is to improve the saving effect of the terminal. For another example, the energy saving effect of the first mode is higher than the energy saving effect of the second mode. In this way, compared with the terminal being kept in the second mode, the saving effect of the terminal can also be improved.

Alternatively, the above-mentioned first mode and the above-mentioned second mode may be two modes with different parameters. For example, the first mode may be a mode configured with same slot scheduling, for example, the minimum K0 is 0, and the second mode It may be a mode configured with cross-slot scheduling (cross-slot scheduling), for example, the minimum K0 is 1. Of course, the second mode may also be a mode configured with same slot scheduling, and the first mode may be a mode configured with cross-slot scheduling (cross-slot scheduling); for another example: the first mode may be configured A relatively large maximum downlink or maximum uplink multiple-input multiple-output layer (DL/UL MIMO layer) (for example, the maximum downlink MIMO layer is 4 layers, or the maximum uplink MIMO layer is 2 layers) mode, and the first mode can be configured It is a relatively small maximum downlink or maximum uplink multiple-input multiple-output layer (DL/UL MIMO layer) (for example, the maximum downlink MIMO layer is 2 layers, or the maximum uplink MIMO layer is 1 layer) mode.

In the embodiments of the present disclosure, the switching from the first mode to the second mode when the second timer expires can improve the transmission flexibility of the terminal, and further improve the energy-saving effect of the terminal, for example, from the energy-saving effect The poor mode is switched to the mode with good energy-saving effect, or the mode with good energy-saving effect is entered first, and then the mode with poor energy-saving effect is switched to.

It should be noted that it is clear to the network device that the terminal starts or restarts the first timer, because the conditions for the terminal to start or restart the first timer can be configured by the network device, or agreed in the protocol, or the terminal and the network Equipment pre-negotiated, etc. Therefore, when the terminal starts or restarts the first timer, the network device performs scheduled transmission for the terminal entering the first mode.

Similarly, it is clear to the network device that the terminal starts or restarts the second timer, because the conditions for the terminal to start or restart the second timer can be configured by the network device, or agreed in the protocol, or the terminal and the network device may Negotiated and so on. Therefore, when the second timer started or restarted by the terminal expires, the scheduled transmission of the network device for the terminal is switched from the first mode to the second mode.

As an optional implementation manner, the foregoing starting or restarting the second timer includes:

In the case of receiving the PDCCH, start or restart the second timer.

Wherein, in the foregoing case of receiving the PDCCH, it may be that before the second timer is started, or after the second timer is started, and the PDCCH is received when the second timer expires or has not expired, the PDCCH is started or restarted. The second timer.

The above-mentioned PDCCH may be a cell radio network temporary identifier (Cell-Radio Network Temporary Identifier, C-RNTI) or a scheduled configuration radio network temporary identifier (Configured Scheduling Radio Network Temporary Identifier, CS-RNTI) scrambled PDCCH. For example: downlink assignment or uplink grant (downlink assignment or uplink grant) scheduling PDCCH.

Alternatively, the above-mentioned PDCCH is a PDCCH for scheduling new transmission (or called initial transmission). Among them, the new transmission may refer to the first transmission or initial transmission of the service packet, rather than retransmission.

In this way, it is possible to start or restart the second timer only when the PDCCH is scheduled for the terminal to transmit, and switch to the second mode when the second timer expires, so as to save energy consumption of the terminal. For example: before the drx-InactivityTimer expires, if the terminal does not receive the scheduled PDCCH within a certain period of time (the effective time of the second timer), the terminal can enter the configuration of cross-slot scheduling (cross-slot scheduling) or relatively small The largest DL/UL MIMO layer mode can save power.

Optionally, in the case of receiving the PDCCH, starting the second timer includes:

In the case that the PDCCH is received in the first mode, the second timer is started, and the terminal is maintained in the first mode before the second timer expires.

Wherein, in the foregoing case that the PDCCH is received in the first mode, starting the second timer may be, after starting or restarting the first timer, after entering the first mode, and the first timing Before the timer expires, if the PDCCH is received, the second timer is started.

Optionally, the restarting the second timer in the case of receiving the PDCCH includes:

In the second mode and the first timer has not expired, if the PDCCH is received, the second timer is restarted, and the second mode is switched back to the first Mode; or

In the case that the second timer has not expired, if the PDCCH is received, restart the second timer.

Wherein, the above-mentioned being in the second mode may refer to a case where the second timer times out, because the second timer times out, the switching to the above-mentioned second mode is performed.

In this implementation manner, it may be in the second mode and the first timer has not expired, and if the PDCCH is received, the step of restarting the second timer is executed, and the step of restarting the second timer is performed from the first timer. The second mode is switched back to the first mode.

Because when the second timer expires and the first timer does not expire, if the PDCCH is received, the second timer is restarted and the first mode is switched back, which makes it easier for the terminal to monitor Subsequent PDCCH. Of course, if the second timer expires after restarting the second timer, then switch back to the second mode.

In the foregoing case that the second timer has not expired, if the PDCCH is received, restarting the second timer may be, after starting the second timer, in the first mode, if the PDCCH is received, then The second timer is restarted, and the terminal may be maintained in the first mode before the second timer expires.

As an optional implementation manner, the method further includes:

When the first timer expires, entering the second mode, wherein the entering the second mode includes:

Switch from the first mode to the second mode, or maintain the second mode.

Wherein, the terminal may be in the second mode and the first timer has timed out to maintain the second mode, or it may be that the terminal is in the first mode and the first timer has timed out, so that the first mode is switched to the second mode. Two mode. For example: when the second timer expires and the first timer does not expire, if the PDCCH is received, the second timer is restarted to switch from the second mode back to the first mode. In this case, the terminal may be When the terminal is in the first mode, the first timer expires.

In this implementation manner, since the second mode is entered when the first timer expires, the energy consumption of the terminal can be saved in this way.

Optionally, after the first timer expires, if the PDCCH is received in a short discontinuous reception period (drx-ShortCycle), the first mode is entered, and the second timer is started or restarted.

Wherein, the above-mentioned starting or restarting of the second timer may be the starting or restarting of the second timer when the PDCCH is received. For details, please refer to the corresponding description of the above-mentioned embodiment, which will not be repeated here.

Wherein, before entering the drx-ShortCycle, the terminal may be in a long discontinuous reception cycle (longDRX-Cycle) or in another drx-ShortCycle, which is not limited.

In this embodiment, since the PDCCH is received in the drx-ShortCycle, the first mode is entered, and the second timer is started or restarted, so that mode switching can be performed under the drx-ShortCycle, which is beneficial to improve the energy-saving effect of the terminal.

Optionally, the terminal acquires a short DRX (short DRX) parameter configuration with network configuration, and after the first timer expires, performs related operations according to the short DRX parameter configuration.

Wherein, the above parameter configuration may include drx-ShortCycle, for example: activation time and sleep time.

The above-mentioned related operation according to the parameter configuration of the short DRX may be to monitor the PDCCH during the active time of the drx-ShortCycle, but not to monitor the PDCCH during the sleep time.

In addition, when performing related operations according to the parameter configuration of the short DRX, if the PDCCH is received in the drx-ShortCycle, the first mode can be entered, and the second timer can be started or restarted.

It should be noted that after the above-mentioned first timer expires, it is not limited to enter the second mode. For example, it may also be to enter the sleep mode.

As an optional implementation manner, the above-mentioned parameters of the first mode include at least one of the following parameters:

Minimum K0 (minimum K0), minimum K1 (minimum K1), minimum K2 (minimum K2), maximum downlink multiple input multiple output MIMO layers (DL maximum MIMO layers;) and maximum uplink MIMO layers (UL maximum MIMO layers);

The parameters of the second mode include at least one of the following parameters:

Minimum K0, minimum K1, minimum K2, maximum number of downlink MIMO layers and maximum number of uplink MIMO layers;

Wherein, the value of at least one parameter in the parameter of the first mode and the parameter of the second mode is different.

In the embodiment of the present disclosure, K0 may indicate the time interval between the PDCCH and the physical downlink shared channel (PDSCH) scheduled by the PDCCH;

In the embodiment of the present disclosure, K2 may represent the time interval between the PDCCH and the physical uplink shared channel (PUSCH) scheduled by the PDCCH;

In the embodiment of the present disclosure, K1 may be the time interval between the PDSCH and the corresponding physical uplink control channel (Physical Uplink Control Channel, PUCCH) confirming the ACK message or denying the NACK message.

Taking the first mode as an example, the above-mentioned minimum K0 may be the minimum K0 in the first mode, for example: the minimum K0=0 for the same slot scheduling, and the minimum K0 for cross-slot scheduling (cross-slot scheduling) 0, such as K0=1 slot. Since the minimum K0 is included, the terminal can perform corresponding operations according to the minimum K0 to save the energy consumption of the terminal. For example, when the minimum K0 is 1 time slot, then after the terminal receives the PDCCH, it will be in the time slot where the PDCCH is located. There is no need to receive the PDSCH, so there is no need to buffer the PDSCH in the time slot that may be sent to itself, thereby saving energy consumption. In the same way, the energy consumption of the terminal can also be saved by setting the above minimum K1 and minimum K2 values.

Taking the foregoing first mode as an example, the foregoing maximum number of downlink MIMO layers may be the maximum number of downlink MIMO layers in the first mode, for example: 4 layers or 2 layers. Since the maximum number of downlink MIMO layers is included, the terminal can perform corresponding operations according to the maximum number of downlink MIMO layers to save energy consumption of the terminal. For example, when the maximum number of downlink MIMO layers is 2 layers, the terminal only needs to turn on 2 receiving antennas. (Or antenna group or antenna unit or receiving channel), so there is no need to turn on all receiving antennas to save energy. In the same way, the energy consumption of the terminal can also be saved through the above-mentioned maximum uplink MIMO layer number.

In addition, the different values of at least one parameter in the parameters of the first mode and the parameters of the second mode may be that there is at least one parameter among all the parameters in the first mode and all the parameters in the second mode. The value of is different. For example, the first mode and the second mode include at least two of the minimum K0, minimum K1, minimum K2, maximum number of downlink MIMO layers, and maximum number of uplink MIMO layers, while the first mode The parameter of and the parameter of the second mode may have a different value for one of the parameters, such as a different value for the minimum K0, or a different value for the maximum number of downlink MIMO layers, etc.

It should be noted that in the embodiments of the present disclosure, the parameter items included in the first mode and the second mode may be the same or different. For example, the parameters of the first mode include minimum K0, minimum K1, minimum K2, and maximum downlink MIMO layer. The parameters of the second mode include all or part of the minimum K0, the minimum K1, the minimum K2, the maximum downlink MIMO layer number, and the maximum uplink MIMO layer number. For example: when the parameters of the first mode and the parameters of the second mode both include the minimum K0, the minimum K0 of the first mode and the minimum K0 of the second mode may have different values, such as the minimum K0 of the first mode. The value is less than the value of the minimum K0 of the second mode; or when the parameters of the first mode and the parameters of the second mode both include the minimum K1, the values of the minimum K1 of the first mode and the minimum K1 of the second mode can be Different, such as the value of the minimum K1 of the first mode is less than the value of the minimum K1 of the second mode; or when the parameters of the first mode and the parameters of the second mode both include the minimum K2, the minimum K2 of the first mode The minimum K2 value of the second mode can be different, for example, the minimum K2 value of the first mode is less than the minimum K2 value of the second mode; or the parameters of the first mode and the second mode include the maximum value. In the case of the number of downlink MIMO layers, the maximum number of downlink MIMO layers in the first mode and the maximum number of downlink MIMO layers in the second mode can be different. For example, the value of the maximum number of downlink MIMO layers in the first mode is greater than that in the second mode. The value of the maximum number of downlink MIMO layers; or when the parameters of the first mode and the parameters of the second mode both include the maximum number of uplink MIMO layers, the maximum number of uplink MIMO layers in the first mode and the maximum number of uplink MIMO in the second mode The value of the number of layers can be different, for example, the value of the maximum number of uplink MIMO layers in the first mode is greater than the value of the maximum number of uplink MIMO layers in the second mode.

In the embodiment of the present disclosure, when the first timer is started or restarted, the first mode is entered, and the first timer is drx-InactivityTimer; the second timer is started or restarted, when the second timer expires In this case, switching from the first mode to the second mode. In this way, the transmission flexibility of the terminal can be improved, and the energy-saving effect of the terminal can also be improved.
