In fourth and fifth generation mobile communication systems (4G, 5G or NR systems), a DRX (discontinuous reception) mechanism is introduced. The terminal is in an active state during the DRX on period and monitors a downlink control channel; and the system is in an inactive state during DRXoff, and does not listen to a downlink control channel.

The terminal detects an energy-saving signal in a first DRX on period on BWP1, and then the terminal monitors a downlink control channel until N PDCCHs are continuously monitored, or a first timer is overtime, or the first DRX on is finished; if the energy-saving signal is not detected during the second DRX on period, the terminal stops monitoring the downlink control channel; and when the energy-saving signal is detected in the third DRX on period, the terminal monitors the downlink control channel until N PDCCHs are continuously monitored, or the first timer is overtime, or the third DRX on is finished.
In an alternative embodiment, the terminal determines that a transition from the first BWP to the second BWP is required.
Wherein, the energy-saving signal configuration information on the second BWP is the same as or different from the energy-saving signal configuration information on the first BWP;
alternatively, no power save signal configuration information is configured on the second BWP.
Optionally, the terminal determines to switch from the first BWP to the second BWP according to the following:
in the method 1, after determining that a second timer is overtime, the terminal switches from the first BWP to a second BWP;
the second Timer of the embodiment of the invention is a BWP Inactivity Timer which is configured based on a serving cell, and when the BWP Inactivity Timer in a serving cell is overtime, the terminal performs BWP conversion; wherein the second BWP may be default BWP, initial BWP, or any other type of BWP.
In the mode 2, the terminal receives a conversion instruction sent by the network side device and converts the first BWP into a second BWP;
correspondingly, the network side equipment sends a conversion instruction to the terminal; the transition indication may be used to instruct the terminal to transition from the first BWP to a second BWP.
The operations performed by the terminal after the conversion are described separately for different cases below.
In case one, the terminal detects the power saving signal on the first BWP and the terminal determines that the preset condition for stopping listening to the downlink control channel is not satisfied, and configures power saving signal configuration information on the second BWP.
It should be noted that, in case one, the terminal detects the power saving signal and does not start to listen to the downlink control channel in the state of the first BWP, or the terminal detects the power saving signal and listens to the downlink control channel in the state of the first BWP;
the preset condition that the terminal stops monitoring the downlink control channel is part or all of the following conditions:
the method comprises the following steps that under the first condition, a terminal continuously monitors N PDCCHs;
the terminal determines that the first timer is overtime;
and thirdly, the terminal determines that the DRX on is finished.
In case one, after the terminal is switched to the second BWP, the terminal listens to the downlink control channel on the second BWP; and stopping intercepting the downlink control channel on the second BWP when the preset condition is determined to be met.
Specifically, after the terminal is switched to the second BWP, the terminal continues to listen to the downlink control channel on the second BWP according to the energy-saving configuration information of the first BWP until the terminal determines that the preset condition for stopping listening to the downlink control channel is satisfied;
after the terminal determines that the preset condition for stopping intercepting the downlink control channel is met, because the energy-saving signal configuration information is configured on the second BWP, the terminal intercepts the downlink control channel on the second BWP according to the energy-saving signal configuration information on the second BWP.
Optionally, the terminal listens to the downlink control channel on the second BWP in the following manner:
the terminal detects a power saving signal corresponding to the terminal on the second BWP according to the power saving signal configuration information on the second BWP; and after the power-saving signal is detected, a downlink control channel is intercepted on the second BWP.
The operation performed by the terminal after switching to the second BWP in case one will be described with reference to the drawings.
As shown in fig. 6, the first BWP is BWP1, the second BWP is BWP2, and the energy saving signal configuration information is configured on BWP1 and BWP 2; the power save signal configuration information on BWP1 is shown in fig. 6 for power save signal resource pool 1, and the power save signal configuration information on BWP2 is shown in fig. 6 for power save signal resource pool 2.
When BWP1 is active BWP, the terminal detects a power save signal on BWP1, wherein the slash boxes in power save signal resource pool 1 indicate that the terminal detects the power save signal; the terminal listens to the downlink control channel on BWP1 as shown by the grid area during the first DRX on in fig. 6. Assume that the terminal transitions from BWP1 to BWP2 at time t1 and that the terminal is listening to the downlink control channel on BWP1 before the transition; after the terminal switches to BWP2, continuing to listen to the downlink control channel at BWP2 until the terminal determines that the preset condition for stopping listening to the downlink control channel is satisfied; as shown in fig. 6, assuming that the preset condition is DRX on end, the terminal stops listening to the downlink control channel on BWP2 after the first DRX on end.
Since BWP2 configures the energy-saving signal configuration information, after the second DRX on arrives, if the terminal detects an energy-saving signal, as shown in fig. 6, the slash box in energy-saving signal resource pool 2 indicates that the terminal detects an energy-saving signal; the terminal listens to the downlink control channel on BWP2 as shown by the grid area during the second DRX on in fig. 6.
And in the second situation, the terminal detects the energy-saving signal on the first BWP, the terminal determines that the preset condition for stopping intercepting the downlink control channel is not met, and the second BWP is not configured with energy-saving signal configuration information.
It should be noted that, in case two, the terminal detects the power saving signal and does not start to listen to the downlink control channel in the state of the first BWP, or the terminal detects the power saving signal and listens to the downlink control channel in the state of the first BWP;
the preset condition that the terminal stops monitoring the downlink control channel is part or all of the following conditions:
the method comprises the following steps that under the first condition, a terminal continuously monitors N PDCCHs;
the terminal determines that the first timer is overtime;
and thirdly, the terminal determines that the DRX on is finished.
In case two, after the terminal is switched to the second BWP, the terminal listens to the downlink control channel on the second BWP; and stopping intercepting the downlink control channel on the second BWP when the preset condition is determined to be met.
Specifically, after the terminal is switched to the second BWP, the terminal continues to listen to the downlink control channel on the second BWP according to the energy-saving configuration information of the first BWP until the terminal determines that the preset condition for stopping listening to the downlink control channel is satisfied;
after determining that the preset condition for stopping listening to the downlink control channel is satisfied, the terminal performs a data transceiving operation on the second BWP in a manner that the power saving signal configuration information is not configured on the second BWP.
The terminal performs data transceiving operation on the first BWP according to the energy saving signal configuration information, specifically, detects an energy saving signal, and listens to a downlink control channel after detecting the energy saving signal;
and the terminal executes data transceiving operation on the second BWP in a mode without energy-saving signal configuration information, specifically, does not detect the energy-saving signal and continuously listens to a downlink control channel during DRX on.
The terminal listens to the downlink control channel on the first BWP after switching to the second BWP, and after determining that the preset condition for stopping listening to the downlink control channel is satisfied, performs a data transceiving operation on the second BWP and continuously listens to the downlink control channel during the DRX on.
The following describes operations performed by the terminal after switching to the second BWP in case two with reference to the drawings.
As shown in fig. 7, the first BWP is BWP1, the second BWP is BWP2, and the power saving signal configuration information is configured on BWP1, and the power saving signal configuration information is not configured on BWP 2; the power save signal configuration information on BWP1 is shown as power save signal resource pool 1 in fig. 7.
When BWP1 is active BWP, the terminal detects a power save signal on BWP1, wherein the slash boxes in power save signal resource pool 1 indicate that the terminal detects the power save signal; the terminal listens to the downlink control channel on BWP1 as shown by the grid area during the first DRX on in fig. 7. Assume that the terminal transitions from BWP1 to BWP2 at time t1 and that the terminal is listening to the downlink control channel on BWP1 before the transition; after the terminal switches to BWP2, continuing to listen to the downlink control channel at BWP2 until the terminal determines that the preset condition for stopping listening to the downlink control channel is satisfied; as shown in fig. 7, assuming that the preset condition is DRX on end, the terminal stops listening to the downlink control channel on BWP2 after the first DRX on end.
Since no power saving signal configuration information is configured on BWP2, after the second DRX on arrives, the terminal continuously listens to the downlink control channel during DRX on at BWP2, as shown in the grid area during the second DRX on in fig. 7.
And in case three, the terminal does not detect the power-saving signal on the first BWP, and the power-saving signal configuration information is configured on the second BWP.
It should be noted that, in case three, since the terminal does not detect the power saving signal on the first BWP, the terminal stops listening to the downlink control channel on the first BWP.
After the terminal is switched to the second BWP, the terminal stops monitoring the downlink control channel on the second BWP before determining that the next DRX on moment arrives.
That is, after the terminal is switched to the second BWP, before the next DRX on time arrives, the terminal performs data transceiving operation on the first BWP, i.e., stops listening to the downlink control channel; and after the next DRX on moment is reached, performing data transceiving operation according to the second BWP.
After the next DRX on time arrives, performing data transceiving operation according to a second BWP, specifically:
the terminal detects a power saving signal corresponding to the terminal on a second BWP according to power saving signal configuration information on the second BWP; and after the power-saving signal is detected, a downlink control channel is intercepted on the second BWP.
For example, the terminal transitions from a first BWP to a second BWP during a first DRX on; and the terminal does not detect the energy-saving signal on the first BWP, the terminal stops intercepting the downlink control channel on the first BWP; after the terminal is switched to the second BWP, during the first DRX on, the downlink control channel is stopped to be monitored according to the mode on the first BWP; and after the second DRX on arrives, detecting an energy-saving signal corresponding to the terminal according to the energy-saving signal configuration information on the second BWP, and monitoring a downlink control channel after detecting the energy-saving signal.
The operation performed by the terminal after switching to the second BWP in case three will be described below with reference to the drawings.
As shown in fig. 8, the first BWP is BWP1, the second BWP is BWP2, and the energy saving signal configuration information is configured on BWP1 and BWP 2; the power save signal configuration information on BWP1 is shown in fig. 8 for power save signal resource pool 1, and the power save signal configuration information on BWP2 is shown in fig. 8 for power save signal resource pool 2.
When BWP1 is active BWP, the terminal does not detect a power save signal on BWP 1; the terminal stops listening to the downlink control channel on BWP 1. Assuming that the terminal transitions from BWP1 to BWP2 at time t1, after the terminal transitions to BWP2, it continues to stop listening to the downlink control channel at BWP2 until after the next DRX on arrives.
Since BWP2 configures the energy-saving signal configuration information, after the second DRX on arrives, if the terminal detects an energy-saving signal, as shown in fig. 8, the slash box in energy-saving signal resource pool 2 indicates that the terminal detects an energy-saving signal; the terminal listens to the downlink control channel on BWP2 as shown by the grid area during the second DRX on in fig. 8.
In case four, the terminal does not detect the power save signal on the first BWP, and the power save signal configuration information is not configured on the second BWP.
It should be noted that in case four, since the terminal does not detect the power saving signal on the first BWP, the terminal stops listening to the downlink control channel on the first BWP.
After the terminal is switched to the second BWP, the terminal stops monitoring the downlink control channel on the second BWP before determining that the next DRX on moment arrives.
That is, after the terminal is switched to the second BWP, before the next DRX on time arrives, the terminal performs data transceiving operation on the first BWP, i.e., stops listening to the downlink control channel; after the next DRX on moment is reached, executing the operation of receiving and sending data according to the second BWP;
since the second BWP is not configured with the power saving signal configuration information, the operation of transceiving data on the second BWP is specifically to continuously listen to the downlink control channel during DRX on without detecting the power saving signal.
The operation performed by the terminal after switching to the second BWP in case four will be described below with reference to the drawings.
As shown in fig. 9, the first BWP is BWP1, the second BWP is BWP2, and the power saving signal configuration information is configured on BWP1, and the power saving signal configuration information is not configured on BWP 2; the power save signal configuration information on BWP1 is shown as power save signal resource pool 1 in fig. 9.
When BWP1 is active BWP, the terminal does not detect a power save signal on BWP 1; the terminal stops listening to the downlink control channel on BWP 1. Assuming that the terminal transitions from BWP1 to BWP2 at time t1, after the terminal transitions to BWP2, it continues to stop listening to the downlink control channel at BWP2 until after the next DRX on arrives.
Since no power saving signal configuration information is configured on BWP2, after the second DRX on arrives, the terminal continuously listens to the downlink control channel during DRX on at BWP2, as shown in the grid area during the second DRX on in fig. 9.
In addition, the terminal generates BWP conversion, and the terminal is converted from the first BWP to the second BWP; if the energy-saving signal configuration information is not configured on the first BWP, after the terminal is converted to a second BWP, the operation of downlink control channel interception is executed according to the energy-saving signal configuration information on the second BWP;
specifically, the terminal detects a power saving signal corresponding to the terminal on the second BWP according to the power saving signal configuration information on the second BWP; and after the power-saving signal is detected, the downlink control channel is intercepted on the second BWP.
