In a specific embodiment of the present invention, a downlink control information DCI indication signaling is sent to a terminal; and the dormancy parameter or instruction and the DRX parameter or instruction are positioned in a preset functional domain of the DCI indication signaling.

According to the embodiment, the terminal dormancy energy conservation can be dynamically indicated, and the terminal energy conservation can be realized more flexibly; and the BWP indication domain or the resource allocation domain of multiplexing DCI reduces the modification to the existing protocol DCI format.

The terminal detects DCI, where the preset value of the resource allocation domain (continuous allocation mode) corresponds to sleep signaling, and the specific 4 values of the resource allocation domain may correspond to 4 sleep durations. Specifically, the terminal detects that the resource allocation domain corresponds to the sleep instruction, and the sleep time corresponding to the specific value is 10 time slots. The terminal immediately goes to sleep (in this case, the slot count is 1 sleep slot, the terminal needs to sleep 9 more slots); or go to sleep in the next slot to the slot in which the sleep signaling is located (the terminal needs to sleep an additional 10 slots). After the sleep is finished, the terminal re-detects the time slot in bwp#1 or performs time-frequency synchronization and other operations.

In a specific embodiment of the present invention, the DRX parameters or instructions include: at least one of a long DRX cycle period and a short DRX cycle period.

For example, the terminal attaches to bwp#0, and if the terminal receives DCI in which the BWP indicator in the DCI instructs the terminal to switch to bwp#1, the terminal switches to bwp#1 and performs monitoring, data reception, or data transmission in a prescribed very short time. The sleep duration or DRX parameters may be configured (sleep duration) per BWP: the bandwidth of the BWP may be configured as 0 RBs (bandwidth of 0), and the BWP may configure a corresponding sleep duration. The bandwidth of BWP is configured as n RBs (non-zero bandwidth), and the BWP may configure a corresponding sleep duration or DRX parameter; when the terminal is switched from the source BWP to the target BWP: if the target BWP configures the sleep duration, the terminal sleeps according to the configured sleep duration; if the BWP is not configured with specific dormancy time length, the terminal dormancy according to preset dormancy time length; the bandwidth of the target BWP may be 0 RBs (resource blocks) or a preset number of RBs.

In step 228, for example, the terminal configures two BWP, including: BWP1, bandwidth is 10MHz; BWP2, bandwidth 10MHz; at this time, the terminal attaches to BWP1, and BWP2 configures a DRX parameter (DRX 2); the terminal switches from BWP1 to BWP2 according to the scheduling information in the DCI, and performs corresponding data transmission on the target BWP (i.e. BWP 2), and after the data transmission flow is completed, the terminal enters the DRX parameter of BWP2 to enter the DRX state.

In step 229, for example, the terminal configures two BWP, including: BWP1, bandwidth is 10MHz; BWP2, bandwidth 10MHz; at this time, the terminal attaches to BWP1, and BWP2 configures a DRX parameter (DRX 2); the terminal switches from BWP1 to BWP2 according to the scheduling information in the DCI, and performs corresponding data transmission on the target BWP (i.e. BWP 2), the data is not successfully transmitted, and the DRX parameter of the terminal entering the BWP2 enters the DRX state; alternatively, a timer may be started at this time, and after the timing of the timer is finished, the terminal still fails to transmit, and enters the DRX state with the DRX parameter of BWP 2.

Accordingly, the step 22 may include:

step 230, on the source BWP, entering a DRX state according to the DRX parameters; or alternatively

Step 231, on the source BWP, after the downlink data or the uplink data is transmitted, entering a DRX state according to the DRX parameter; or alternatively

In the foregoing embodiment, the bandwidth of the target BWP is configured as zero resource blocks RBs or a preset number of resource blocks RBs. The DRX parameters or instructions include: at least one of a long DRX cycle period and a short DRX cycle period.

In the foregoing embodiment, the bandwidth of the BWP is configured as zero resource blocks RBs or a preset number of resource blocks RBs.

In a wireless network, when there is data to be transmitted, a User Equipment (UE) needs to monitor a physical downlink control channel (Physical Downlink Control Channel, PDCCH) all the time, and send and receive data according to an indication message sent by a network side, so that power consumption of the UE and delay of data transmission are both relatively large. A discontinuous reception mechanism (Discontinuous Reception, DRX) power saving policy is introduced in the LTE system, defining medium access control (Media Access Control, MAC) at the physical layer. According to the working state of DRX, the method is divided into Idle-DRX and Connected-DRX. In Idle-DRX mode, UE has no radio resource connection, and mainly completes monitoring of calling channel and broadcast channel, and only needs to configure fixed sleep period in order to achieve discontinuous reception. The DRX cycle in idle mode is divided into an active period and a sleep period. In Connected-DRX mode, the UE has three states, namely an active period, a short DRX cycle (light sleep period) and a long DRX cycle (deep sleep period), in which the UE is in a power consumption mode; during the light and deep sleep periods, the UE is in a power saving mode.

In the above embodiment of the present invention, after the DRX state is finished, the terminal may switch to the source BWP again to perform operations such as channel detection or time-frequency synchronization, or may leave the target BWP to perform operations such as channel detection or time-frequency synchronization. In the embodiment, the terminal can more flexibly realize terminal energy conservation according to the indication signaling; and the BWP indication field of the DCI is multiplexed, reducing modification to the DCI format.
