In one embodiment of the present invention, preferably, the length of the wake-up period is inversely related to the mobility of the terminal.
In this embodiment, it is considered that the terminal needs to synchronize with the network side, and the synchronization is based on the mobility of the terminal, so when the mobility of the terminal is high, a shorter wake-up period is set for the terminal, and when the mobility of the terminal is low, a longer wake-up period is set for the terminal, so as to ensure the effect of keeping the terminal and the network side synchronized.
Further, in this embodiment, for example, if the mobile speed of the terminal is 120km/h, the wake-up period for receiving the wake-up signal is 6 DRX cycles, but when the speed of the terminal is increased to 250km/h, the wake-up period for receiving the wake-up signal is 2 DRX cycles, although the mobile speed may not be a certain value, but within a certain interval, the mobile speed is the same for the wake-up period corresponding to the terminal within the interval.

In the apparatus 60 for determining an awake period provided by the present invention, the terminal receives the awake period configured by the base station, and wakes up according to the awake period to receive the awake signal. The awake cycle can be related to a DRX cycle, the awake cycle is an integer multiple of the DRX cycle, for example, the awake cycle is configured to 3 DRX cycles, and the terminal can keep synchronization with the network side when waking for 3 DRX cycles. Or the wakeup period is configured directly, independent of the DRX period, and the wakeup period is greater than the preset period, where the preset period is the wakeup period in the related art, and the wakeup period in the related art is, for example, 1280us, and the wakeup period is set as large as possible to further save power for the terminal while the terminal and the network side (base station) remain unsynchronized. By adopting the technical scheme of the invention, the wake-up signal can be received according to the wake-up period which is clearly defined, so that the terminal can be ensured to save more power.

a processing module 704, configured to monitor a downlink control channel according to the wake-up signal, and maintain time and frequency synchronization with the base station.
In this embodiment, after receiving the wake-up signal, the terminal enters a wake-up state according to the instruction of the wake-up signal, and monitors the PDCCH in the wake-up state. In addition, the terminal in the DRX mechanism maintains time and frequency synchronization with the network side (base station side), thereby ensuring accurate data transceiving.
In particular embodiments, the receiving module 702 may be a receiver or an antenna, etc., and the processing module 604 may be a central processor or a baseband processor, etc.

In this embodiment, when the terminal supports the DRX mechanism, the awake cycle is an integer multiple of the DRX cycle, for example, the awake cycle is configured to be 3 DRX cycles, and the terminal can keep synchronization with the network side when waking up for 3 DRX cycles; when the terminal does not support the DRX mechanism, the wakeup period is directly configured and is irrelevant to the DRX period, the wakeup period at the time is larger than a preset period, the preset period is the wakeup period in the related technology, and the wakeup period of the terminal in the WUS mode can be clearly defined.
In one embodiment of the present invention, preferably, when the mobility of the terminal is higher than a preset threshold, the wake-up period is equal to the period of the discontinuous reception mechanism.
In this embodiment, in consideration of the mobility of the terminal, if the mobility of the terminal is high, the base station configures the wake-up period to be consistent with the DRX period, so as to ensure that the terminal and the network side keep synchronous. As shown in fig. 2, the DRX cycle of the terminal is composed of an awake cycle and a sleep cycle, and the terminal wakes up briefly according to the awake cycle to receive the awake signal, wherein the awake cycle is equal to the DRX cycle.
In one embodiment of the present invention, preferably, the length of the wake-up period is inversely related to the mobility of the terminal.
In this embodiment, it is considered that the terminal needs to synchronize with the network side, and the synchronization is based on the mobility of the terminal, so when the mobility of the terminal is high, the wake-up period is shorter, and when the mobility of the terminal is low, the wake-up period is longer, so as to ensure the effect of keeping the terminal and the network side synchronized.
Further, in this embodiment, for example, if the mobile speed of the terminal is 120km/h, the wake-up period for receiving the wake-up signal is 6 DRX cycles, but when the speed of the terminal is increased to 250km/h, the wake-up period for receiving the wake-up signal is 2 DRX cycles.
