Please refer to FIG. 1. FIG. 1 is a structural diagram of a network system to which an embodiment of the present invention can be applied. As shown in FIG. 1, it includes a terminal 11 and a network device 12, where the terminal 11 may be a user terminal (User Equipment, UE).

It should be noted that, in the embodiment of the present invention, only a 5G base station is used as an example, but the specific type of the network device 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 invention. The method is applied to a terminal, as shown in FIG. 2, and includes the following steps:

Step 201: Enter a first mode when a first timer is started or restarted, 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 a new transmission (or referred to as an initial transmission) during an active time (active time). It should be noted that, in this embodiment of the present invention, the conditions for starting or restarting the first timer are not limited, for example, it may be a condition newly defined in a subsequent protocol version to start or restart the drx-InactivityTimer.

The above-mentioned first mode may be referred to as a 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 : The downlink MIMO layer is configured as a 4-layer mode, or the uplink MIMO layer is configured as a 2-layer mode, and so on.

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

The above-mentioned second timer may be configured by the network side, for example, configured by the network side through RRC signaling, or the above-mentioned second timer may be a timer pre-agreed by a protocol. In addition, the above-mentioned second timer may be N time slots (slots), N mini-slots (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 starts or restarts after the 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 timer expires, switch from the first mode to the second mode before the first timer expires, thereby improving the transmission flexibility before the drx-InactivityTimer expires.

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

Further, the above-mentioned first mode and the above-mentioned 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 that switching from the first mode to the second mode can be performed. It is to improve the saving effect of the terminal. For another example, the energy saving effect of the first mode is higher than that of the second mode, so that the saving effect of the terminal can also be improved compared to that the terminal is kept in the second mode all the time.

Alternatively, the first mode and the second mode may be 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 can be a mode configured with 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; for another example, the first mode may be configured with 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 A mode in which the maximum downlink or the maximum uplink multiple-input multiple-output (DL/UL MIMO layer) is relatively small (for example, the maximum downlink MIMO layer is 2 layers, or the maximum uplink MIMO layer is 1 layer).

In the embodiment of the present invention, since the first mode is switched to the second mode when the second timer expires, the transmission flexibility of the terminal can be improved, and the energy-saving effect of the terminal can be further improved. The mode with poor energy-saving effect is switched to the mode with good energy-saving effect, or firstly enter the mode with better energy-saving effect, and then switch to the mode with poor energy-saving effect.

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

Similarly, it is clear for 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 may be configured by the network device, or agreed in the protocol, or the terminal and the network device may be pre-determined. negotiated etc. Therefore, when the second timer started or restarted by the terminal expires, the network device switches from the first mode to the second mode for the scheduled transmission of the terminal.

As an optional implementation manner, the above-mentioned starting or restarting of the second timer includes:

In the case of receiving the PDCCH, the second timer is started or restarted.

The above-mentioned case of receiving the PDCCH 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 does not expire, then start or restart all the second timer.

The above PDCCH may be a PDCCH scrambled by a Cell-Radio Network Temporary Identifier (C-RNTI) or a Scheduled Scheduling Radio Network Temporary Identifier (CS-RNTI). For example: scheduling PDCCH of downlink assignment or uplink grant.

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

In this way, the second timer can be started or restarted only when the above-mentioned PDCCH transmits for the scheduling terminal, and when the second timer expires, the second mode is switched to save the energy consumption of the terminal. For example: before the drx-InactivityTimer times out, if the terminal does not receive the scheduled PDCCH within a certain period of time (the valid time of the second timer), the terminal can enter the configuration with cross slot scheduling or a relatively small The maximum DL/UL MIMO layer mode can save power.

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

If the PDCCH is received in the first mode, the second timer is started, and the terminal remains in the first mode until the second timer expires.

Wherein, when 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 timer Before the timer expires, if the PDCCH is received, the second timer is started.

Optionally, when the PDCCH is received, restarting the second timer includes:

In the second mode and the first timer does not expire, 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 timed out, if the PDCCH is received, the second timer is restarted.

Wherein, the above-mentioned in the second mode may refer to the case in which the second timer times out, because the second mode is switched to the above-mentioned second mode when the second timer times out.

In this embodiment, in the second mode, and the first timer has not expired, returning to the step of restarting the second timer if the PDCCH is received, and starting from the first timer. The second mode switches back to the first mode.

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

In the above-mentioned case that the second timer does not expire, if the PDCCH is received, restarting the second timer may be, after the second timer is started, in the first mode, if the PDCCH is received, then: The second timer is restarted, and the terminal may remain in the first mode until the second timer expires.

As an optional embodiment, 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.

The terminal may be in the second mode and the first timer expires, thereby maintaining the second mode, or it may be that the terminal is in the first mode and the first timer expires, so that the first mode switches to the first mode. Second mode. For example, when the second timer expires and the first timer does not expire, if the PDCCH is received, restart the second timer to switch from the second mode to the first mode. In this case, the terminal may be When the terminal is in the first mode, the first timer times out.

In this embodiment, since the second mode is entered when the first timer times out, the power consumption of the terminal can be saved.

Optionally, after the first timer expires, if a PDCCH is received in a short discontinuous reception cycle (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 starting or restarting the second timer in the case of receiving the PDCCH. For details, reference may be made 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 may be in another drx-ShortCycl, 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 in the drx-ShortCycle, which is beneficial to improve the energy-saving effect of the terminal.

Optionally, the terminal acquires the parameter configuration of short discontinuous reception (short DRX) configured by the network, and after the first timer expires, performs related operations according to the parameter configuration of the short DRX.

The above parameter configuration may include drx-ShortCycle, such as activation time and sleep time.

The above-mentioned related operations according to the parameter configuration of the short DRX may be that the PDCCH is monitored during the activation time of the drx-ShortCycle, and the PDCCH is not monitored during the sleep time.

In addition, when the related operation is performed 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 enter the sleep mode.

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

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

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

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

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

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

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

In the embodiment of the present invention, K1 may be a time interval between an ACK message or a ACK message on the corresponding physical uplink control channel (Physical Uplink Control Channel, PUCCH) on the PDSCH.

Taking the first mode as an example, the above-mentioned minimum K0 may be the smallest K0 in the first mode, for example: minimum K0=0 for same slot scheduling, minimum K0> for cross slot scheduling 0, such as K0=1 time slot (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, after the terminal receives the PDCCH, the time slot where the PDCCH is located The PDSCH does not need to be received during the time slot, so there is no need to buffer the PDSCH that may be sent to itself in the time slot, thereby saving energy consumption. Similarly, by setting the values of the minimum K1 and the minimum K2, the energy consumption of the terminal can also be saved.

Taking the above-mentioned first mode as an example, the above-mentioned 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 performs corresponding operations according to the maximum number of downlink MIMO layers to save the energy consumption of the terminal. For example, when the maximum number of downlink MIMO layers is 2, the terminal only needs to open 2 receiving antennas (or antenna group or antenna unit or receiving channel), so that all receiving antennas do not need to be turned on, so as to save energy consumption. Similarly, the above-mentioned maximum uplink MIMO layers can also save the energy consumption of the terminal.

In addition, the difference in value of at least one of 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 of the first mode and all the parameters of the second mode The values are different, for example: the first mode and the second mode include at least two of the minimum K0, the minimum K1, the minimum K2, the maximum number of downlink MIMO layers and the maximum number of uplink MIMO layers, while the first mode The parameter of , and the parameter of the second mode may have different values of one of the parameters, for example, the value of the minimum K0 is different, or the value of the maximum number of downlink MIMO layers is different.

It should be noted that, in this embodiment of the present invention, 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 the minimum K0, the minimum K1, the minimum K2, and the maximum downlink MIMO layer. and the maximum number of uplink MIMO layers, the parameters of the second mode include all or part of the minimum K0, minimum K1, minimum K2, maximum downlink MIMO layers, and maximum uplink MIMO layers. For example: when the parameters of the first mode and the parameters of the second mode both include the minimum K0, the values of the minimum K0 of the first mode and the minimum K0 of the second mode may be different, such as the minimum K0 of the first mode. The value is smaller than the value of the minimum K0 of the second mode; or in the case that 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, for example, the value of the minimum K1 of the first mode is smaller than the value of the minimum K1 of the second mode; or if 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 value of the minimum K2 of the second mode may be different, for example, the value of the minimum K2 of the first mode is smaller than the value of the minimum K2 of the second mode; or both the parameters of the first mode and the parameters of the second mode include the maximum value. In the case of the number of downlink MIMO layers, the value of the maximum number of downlink MIMO layers in the first mode and the maximum number of downlink MIMO layers in the second mode may 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 if 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 uplink MIMO in the second mode The value of the number of layers may 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 this embodiment of the present invention, 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, and when the second timer expires case, switch 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.
