3. Connected Discontinuous Reception (CDRX):

discontinuous Reception (DRX) can enable a terminal device in a connected state to periodically enter a sleep mode at some time, and not monitor a PDCCH subframe, but wake up from the sleep mode when monitoring is needed, so that the terminal device achieves the purpose of saving power. The DRX mechanism may be implemented when the terminal device is in an idle state or a connected state, where CDRX is discontinuous reception when the terminal device is in the connected state. CDRX control of LTE is divided into an active period and a non-active period, the CDRX active period can be used for detecting a connection state PDCCH, and the CDRX non-active period cannot be used for detecting the connection state PDCCH. As shown in fig. 1, fig. 1 is a schematic diagram of a CDRX activation period and a deactivation period provided in an embodiment of the present application. In a DRX cycle, when any one of an active time timer (on duration timer), an inactive time timer (inactive timer), and a retransmission timer (retransmission timer) maintained by a terminal is running, determining that the terminal device is currently in an active period (active time); otherwise, judging that the terminal equipment is currently in an inactive period (inactive time). Wherein the duration timer is turned on at a fixed location (offset of the network device configuration) per DRX cycle; the inactive timer is started when receiving a PDCCH indicating that new transmission data exists; the retransmission timer is started after receiving a Time interval timer (Hybrid Automatic Repeat reQuest Round-Trip Time timer, HARQ RTT timer) indicating retransmission of data.

The embodiment of the present application may be applied to the network architecture schematic diagram shown in fig. 2, where the network architecture shown in fig. 2 is a network architecture of a wireless communication system, the network architecture generally includes a terminal device and a network device, and the number and the form of each device do not constitute a limitation to the embodiment of the present application. The network device may be a Base Station (BS), and the BS may provide communication services to multiple terminal devices, and multiple Base stations may also provide communication services to the same terminal device.

It should be noted that, in the current LTE terminal scheme, the active period and the inactive period are generally controlled based on the CDRX protocol. The CDRX active period may be used to detect the connected PDCCH, and the CDRX inactive period may not be used to detect the connected PDCCH. For possible PDCCH (Physical Downlink Control Channel) missing, the terminal device may enter an inactive period by mistake, so that the CDRX state of the network device and the CDRX state of the terminal device are inconsistent, thereby causing more PDCCH missing, and reducing the reliability of the connection state service.

In order to improve the reliability of a connected service, the embodiment of the application provides a PDCCH detection method. In order to better understand the PDCCH detection method provided in the embodiments of the present application, the PDCCH detection method is described in detail below.

Referring to fig. 3, fig. 3 is a flowchart of a PDCCH detection method according to an embodiment of the present disclosure, where the PDCCH detection method includes steps 301 to 302. The method execution subject shown in fig. 3 may be a terminal device (for example, as shown in fig. 2), or the subject may be a chip in the terminal device. The method execution subject shown in fig. 3 is exemplified by a terminal device. Wherein:

301. and the terminal equipment detects the PDCCH in a target subframe under the non-activated state, wherein the target subframe is a receiving subframe.

In the embodiment of the application, the terminal device detects the PDCCH by using a target subframe in an inactive period, where the target subframe is a receiving subframe in the inactive period and is used for receiving the PDCCH. Therefore, the terminal equipment detects the PDCCH by using the existing receiving subframe in the inactive period under the condition of not additionally receiving the PDCCH, thereby being beneficial to reducing the power consumption of the terminal equipment and improving the reliability of the connection state service.

In a possible implementation manner, the target subframe is a subframe used for receiving the same-frequency service in an inactive period. That is, the target subframe may be a subframe having the same frequency as the access cell in the inactive period.

Optionally, the subframe used for receiving the same-frequency service in the inactive period includes one or more of the following subframes: a trailing receive subframe, a semi-static persistent scheduling subframe, a measurement subframe. The tailing reception subframe refers to a subframe in a tailing reception process from the first subframe of an inactive period to the real stopping of the PDCCH detection. The semi-persistent scheduling subframe refers to a PDSCH for receiving semi-persistent scheduling, which also needs to receive a PDCCH in an inactive period. The measurement subframe is a subframe for planning a mobility management related measurement task.

302. And if the terminal equipment detects that the PDCCH comprises the downlink control information, the terminal equipment enters an activated state to detect the PDCCH.

In this embodiment, if the terminal device detects that the PDCCH includes downlink control information using the target subframe, it indicates that the CDRX state of the current network device is inconsistent with the CDRX state of the terminal device, that is, the network device is sending the PDCCH, but the terminal device has already entered an inactive state, and therefore the terminal device needs to immediately enter an active state, so as to ensure reliability of a connection state service.

In the method described in fig. 3, the terminal device detects the PDCCH by using a target subframe in an inactive state, where the target subframe is a reception subframe; and if the terminal equipment detects that the PDCCH comprises the downlink control information, immediately entering an activated state to detect the PDCCH. Therefore, based on the method described in fig. 3, it is beneficial to improve the reliability of the connected-state service.

Referring to fig. 4, fig. 4 is a flowchart of a PDCCH detection method according to an embodiment of the present disclosure, where the PDCCH detection method includes steps 401 to 404. The method execution subject shown in fig. 4 may be a terminal device (for example, as shown in fig. 2), or the subject may be a chip in the terminal device. The method shown in fig. 4 is executed by taking a terminal device as an example. Wherein:

401. and the terminal equipment detects the PDCCH in a target subframe in a non-activated state, wherein the target subframe is a receiving subframe.

402. And if the terminal equipment detects that the PDCCH comprises the downlink control information, the terminal equipment enters an activated state to detect the PDCCH.

The specific implementation manners of step 401 and step 402 are the same as those of step 301 and step 302, and are not described herein again.

403. The terminal equipment starts a first timer and a second timer, wherein the second timer is a CDRX related timer.

In the embodiment of the present application, the first timer is a self-defined timer, and is used to limit the minimum time of each activation period. The second timer is a timer specified in the CDRX protocol, and includes an active time timer, a retransmission timer, an inactive time timer, a retransmission data time interval timer, and the like. When the terminal device detects that the PDCCH includes downlink control information, that is, when it indicates that the CDRX state of the current network device is inconsistent with the CDRX state of the terminal device, the terminal device needs to enter an active state to detect the PDCCH, and start a first timer and a second timer. Based on the mode, the method is beneficial to limiting the shortest time of the activation period and reducing the power consumption of the terminal equipment.

404. And when the first timer and the second timer are over time, the terminal equipment enters an inactive state.

In the embodiment of the application, when the terminal device detects that the PDCCH includes downlink control information, the terminal device enters an active state to detect the PDCCH, and starts a first timer and a second timer. And under the condition that the first timer and the second timer are overtime, the terminal equipment returns to the non-activated state from the activated state. That is, when all timers of the terminal device entering the active period are timed out, the terminal device enters the inactive state again.

Exemplarily, as shown in fig. 5, fig. 5 is a schematic diagram of PDCCH detection provided in an embodiment of the present application. In this example, in one DRX cycle, after the terminal device enters an inactive period, the PDCCH is detected by using a trailing receive subframe of the inactive period, and it is detected that the PDCCH includes downlink control information, that is, the PDCCH indicates that there is new data transmission, at this time, the terminal device immediately enters an active state to detect the PDCCH, and starts a first timer and a second timer. When the first timer and the second timer are overtime, namely all the timers in the activation period are overtime, the terminal equipment returns to the non-activation state again.

For another example, as shown in fig. 6, fig. 6 is a schematic diagram of another PDCCH detection provided in the embodiment of the present application. In this example, in one DRX cycle, after the terminal device enters an inactive period, the terminal device detects the PDCCH by using a semi-static persistent scheduling subframe of the inactive period, and detects that the PDCCH includes downlink control information, that is, the PDCCH indicates that there is new data transmission, at this time, the terminal device immediately enters an active state to detect the PDCCH, and starts a first timer and a second timer. When the first timer and the second timer are overtime, namely all the timers in the activation period are overtime, the terminal equipment returns to the non-activation state again.

In a possible implementation manner, the terminal device receives configuration information sent by the network device, where the configuration information is used to configure the first timer. Illustratively, the configuration information may be used to configure the time length of the first timer.

In one possible implementation, the time length of the first timer is related to a signal quality parameter. For example, the network device may configure a time length of the first timer based on the signal quality parameter, and the terminal device limits the time to enter the activation period based on the time length of the first timer configured by the network device. As another example, the terminal device may also configure the time length of the first timer according to the current signal quality parameter.

Optionally, the time length of the first timer may be determined empirically, or may be adjusted based on feedback of the processing result, and the time length of the first timer is not limited in this embodiment.

In the method described in fig. 4, the terminal device detects the PDCCH by using a target subframe in an inactive state, where the target subframe is a reception subframe; and if the terminal equipment detects that the PDCCH comprises the downlink control information, immediately entering an activated state to detect the PDCCH, and starting a first timer and a second timer. Therefore, based on the method described in fig. 4, it is beneficial to improve the reliability of the connected-state service.

Referring to fig. 7, fig. 7 is a schematic structural diagram of a communication device according to an embodiment of the present application. The apparatus may be a terminal device, an apparatus in the terminal device, or an apparatus capable of being used in cooperation with the terminal device. The communication device 70 shown in fig. 7 may include a processing unit 701 and a communication unit 702. The processing unit 701 is configured to perform data processing. The communication unit 702 is integrated with a receiving unit and a transmitting unit. The communication unit 702 may also be referred to as a transceiving unit. Alternatively, communication section 702 may be divided into a reception section and a transmission section. The processing unit 701 and the communication unit 702 are similar, and are not described in detail below. Wherein:

Optionally, the target subframe is a subframe used for receiving a common-frequency service in an inactive period.

Optionally, the subframe used for receiving the same-frequency service in the inactive period includes one or more of the following subframes: a trailing receive subframe, a semi-static persistent scheduling subframe, a measurement subframe.
