Description

Physical downlink control channel monitoring method and terminal equipment Technical Field The present application relates to the field of communications technologies, and in particular, to a physical downlink control channel monitoring method and a terminal device. Background A low power wake-up signal (LP-WUS) is a technology that enables a terminal device to wake up in a low power or sleep state. The power consumption of the terminal equipment in the standby state can be reduced based on the technology, so that the battery life of the terminal equipment is prolonged. At present, the terminal device can enter the wake-up state after receiving the low-power consumption wake-up signal sent by the network device, and keep in the wake-up state within a certain period of time after entering the wake-up state, and stay in the sleep state in other time periods. When the terminal equipment is in the wake-up state, the Physical Downlink Control Channel (PDCCH) can be monitored, and when the terminal equipment is in the sleep state, the PDCCH is not monitored, so that the purpose of reducing the power consumption of the terminal equipment is achieved. However, the low power consumption wake-up signal has weak anti-interference capability, and in case of large interference, it may be difficult for the terminal device to receive the low power consumption wake-up signal, resulting in that the terminal device cannot monitor the PDCCH. Therefore, a solution is needed to solve the above-mentioned problems. Disclosure of Invention The application provides a physical downlink control channel monitoring method and terminal equipment. In order to achieve the above purpose, the application adopts the following technical scheme: In a first aspect, an embodiment of the present application provides a method for monitoring a physical downlink control channel, which is applied to a terminal device, and is configured to receive the number of periods sent by a network device, monitor a low power consumption wake-up signal in N periods, where the low power consumption wake-up signal is used to trigger the terminal device to monitor the physical downlink control channel, and monitor the physical downlink control channel by using a Connected Discontinuous Reception (CDRX) mechanism after the N periods are over when the low power consumption wake-up signal is not monitored in the N periods, where the CDRX mechanism is a mechanism for monitoring the physical downlink control channel by using a radio receiver (MR). According to the physical downlink control channel monitoring method provided by the embodiment of the application, the terminal equipment can monitor the low-power consumption wake-up signal in N periods according to the period number sent by the network equipment, and when the low-power consumption wake-up signal is not monitored in N periods, the terminal equipment starts to monitor the physical downlink control channel by adopting a discontinuous receiving mechanism in a connection state after the N periods are finished. Therefore, even if the terminal equipment cannot monitor the low-power consumption wake-up signal, the terminal equipment can monitor the physical downlink control channel by adopting a discontinuous receiving mechanism in a connection state, and the discontinuous receiving mechanism in the connection state does not depend on the low-power consumption wake-up mechanism. The problem that the terminal equipment cannot monitor the physical downlink control channel for a long time due to weak anti-interference capability of the low-power consumption wake-up signal is avoided, and the monitoring reliability of the physical downlink control channel can be effectively improved. In one possible implementation, the N periods include at least one of N CDRX periods and N periods listening for a low power wake-up signal. In one possible implementation, when the low power wake-up signal is not monitored in N periods, the physical downlink control channel is monitored by using a discontinuous reception mechanism in a connection state after the N periods are finished, including that when the low power wake-up signal is not monitored in N periods, the physical downlink control channel is monitored by using the discontinuous reception mechanism in a connection state at the beginning of the period of the first CDRX after the N periods are finished. In one possible implementation manner, the terminal device may monitor the low power consumption wake-up signal for waking up other terminal devices, and in order to determine that the monitored low power consumption wake-up signal is the low power consumption wake-up signal for waking up itself, in the embodiment of the present application, the terminal device monitors the identification information corresponding to the low power consumption wake-up signal in N periods, and detects whether the identification information corresponding to the low power consumption wake-up signal is
