For example, in actual traffic, the occurrence of traffic is not periodic, and may occur aperiodically, in which case the terminal would be detrimental to the power saving of the terminal if the PDCCH is also monitored on a periodic basis

Based on this, the embodiment of the disclosure provides a PDCCH monitoring method, in which a terminal can monitor signals, and because the signals can be used to instruct the terminal to monitor the monitoring time of a physical downlink control channel, the terminal can determine the monitoring time of the monitoring PDCCH based on the signals, and further the terminal can monitor the PDCCH at the corresponding monitoring time.

Fig. 2 is a flowchart illustrating a PDCCH monitoring method according to an exemplary embodiment, which is performed by a terminal as shown in fig. 2, including the following steps.

In step S11, the signal is monitored.

In some embodiments, the signal may be PDCCH, or other physical channel, or some preset sequence, etc. The signal carries some information, and the signal is used for indicating the monitoring time of the terminal for monitoring the PDCCH, and the information carried in the signal can be obtained by monitoring the signal, so that the monitoring time of the terminal for monitoring the PDCCH is determined.

In some embodiments, the terminal is configured with a monitoring period, based on which the signal is monitored.

In some embodiments, the monitoring period is configured for the network device, or protocol specification, etc. For example, the network device may optionally configure the monitoring period for the terminal, or configure the monitoring period for the terminal based on some historical empirical value. For example, the network device may configure the monitoring period as N discontinuous reception DRX periods or N specific PDCCH search space monitoring periods.

In step S12, a monitoring time for monitoring the PDCCH is determined based on the signal.

Specifically, the signal can directly bear the monitoring time of the monitoring PDCCH, the monitoring time of the monitoring PDCCH can be directly determined based on the signal, and at the moment, the monitoring time of the PDCCH can be predicted and determined by equipment such as a terminal or core network equipment based on an AI model.

Or the terminal is configured with a monitoring period, the monitoring period can be N DRX periods or N specific PDCCH search space monitoring periods, N is a positive integer, N bits can be carried in the signal at this time, each bit corresponds to one DRX period or one specific PDCCH search space monitoring period, and whether to monitor the PDCCH in the corresponding DRX period or the specific PDCCH search space monitoring period is determined based on the bit value of each bit.

Or the terminal is configured with a monitoring period, the monitoring period may be N DRX periods, and the signal may carry a PDCCH search space monitored by the terminal at an active time of each DRX period of the N DRX periods, and the corresponding PDCCH search space is monitored at the active time of each DRX period based on the search space monitored by the terminal at the active time of each DRX period of the N DRX periods.

Or the terminal is configured with a monitoring period, the monitoring period can be N DRX periods or N specific PDCCH searching space monitoring periods, and the signal can bear the corresponding active time of each DRX period in the N DRX periods; or carrying the active time corresponding to each specific PDCCH search space monitoring period in N specific PDCCH search space monitoring periods in the signal, and monitoring PDCCH in the active time corresponding to each DRX period based on the active time corresponding to each DRX period; or monitoring the PDCCH at the active time corresponding to each specific PDCCH search space monitoring period based on the active time corresponding to each specific PDCCH search space monitoring period.

In some embodiments, the PDCCH search space monitored by the terminal at the active time of each of the N DRX cycles is determined based on the probability of traffic generation and/or the amount of traffic generation in the active time of each DRX cycle.

In some embodiments, the active time corresponding to each DRX cycle or the active time corresponding to each specific PDCCH search space monitoring cycle is determined based on the probability of traffic generation and/or the amount of traffic generation in each DRX cycle or each specific PDCCH search space monitoring cycle.

In some embodiments, the probability of traffic generation and/or the amount of traffic generation is determined based on an AI model.

In the embodiment of the disclosure, the terminal monitors the signal, and the signal can be used for indicating the terminal to monitor the monitoring time of the physical downlink control channel, so that the terminal can determine the monitoring time for monitoring the PDCCH based on the signal, and the terminal can monitor the PDCCH at the corresponding monitoring time.

In the method for monitoring PDCCH provided in the embodiments of the present disclosure, the signal carries monitoring time for the terminal to monitor PDCCH.

For example, when the current time is ten points, the monitoring time of the terminal monitoring the PDCCH carried in the signal may be ten-point zero-one, ten-point zero-five, or the like.

In some embodiments, the monitoring time for a terminal carried in the signal to monitor the PDCCH is determined based on AI model predictions. In one embodiment, the terminal determines the monitoring time of the PDCCH to be monitored based on AI model prediction and informs the network device, which configures the signal. In another embodiment, the core network device predicts and determines the monitoring time of the PDCCH based on the AI model, and sends the monitoring time of the PDCCH to the network device, and the network device configures the signal based on the received monitoring time of the PDCCH, so that the signal carries the monitoring time of the PDCCH.

In the embodiment of the disclosure, the terminal can directly determine the monitoring time for monitoring the PDCCH through the monitoring signal, and further the terminal can monitor the PDCCH at the corresponding monitoring time.

In the PDCCH monitoring method provided in the embodiments of the present disclosure, a terminal is based on a periodic monitoring signal, as shown in fig. 3, and fig. 3 shows a flowchart of a PDCCH monitoring method, including the following steps:

In step S21, the signal is monitored based on the monitoring period.

In some embodiments, the terminal determines the configuration information and determines a monitoring period of the monitoring signal based on the configuration information.

The configuration information may be sent by the network device, or may be predefined by a protocol or the like.

For example, the monitoring period is 10ms, then the signal is monitored every 10ms, although the monitoring period herein is merely an example and other possible monitoring periods are possible.

In an embodiment, the signal may carry a monitoring time of the terminal in which the terminal needs to monitor the PDCCH in a monitoring period, for example, if the monitoring period of the terminal monitoring signal is 20ms, the signal carries which time in 20ms the terminal needs to monitor the PDCCH, and then the terminal monitors the PDCCH at the corresponding time.

In the PDCCH monitoring method provided in the embodiments of the present disclosure, the monitoring period is N DRX periods or N specific PDCCH search space monitoring periods.

Wherein the specific PDCCH search space is determined by the network device.

In the PDCCH monitoring method provided in the embodiments of the present disclosure, N bits are carried in a signal, where each bit in the N bits corresponds to one DRX cycle or one specific PDCCH search space monitoring cycle.

In some embodiments, the terminal determines whether to monitor the PDCCH in a DRX cycle or a specific PDCCH search space monitoring cycle corresponding to each bit based on a bit value of each of N bits in the signal.

For example, the monitoring period is 3 DRX periods, including a first DRX period, a second DRX period, and a third DRX period, then the signal carries 3 bits, bit 1 corresponds to the first DRX period, bit 2 corresponds to the second DRX period, bit 3 corresponds to the third DRX period, when the value of bit 1 is a first bit value (e.g. 1), it indicates that the terminal needs to monitor the PDCCH at the active time of the first DRX period, when the value of bit 2 is a second bit value (e.g. 0), it indicates that the terminal does not need to monitor the PDCCH at the active time of the second DRX period,

in the embodiment of the disclosure, the signal carries N bits, and the terminal can determine whether to monitor the PDCCH in the DRX cycle corresponding to each bit or the specific PDCCH search space monitoring cycle based on the bit value of each bit, so that the monitoring time for monitoring the PDCCH is accurately obtained.

In the PDCCH monitoring method provided in the embodiments of the present disclosure, if it is determined that the monitoring period is N DRX periods, the signal carries a PDCCH search space monitored by the active time of the terminal in each DRX period of the N DRX periods.

For example, the higher layer signaling configures M search spaces, where the number of blind tests of PDCCHs corresponding to the M search spaces is different, and then the specific signal may indicate which of the M search spaces configured by the higher layer signaling is the search space monitored by the active time of each DRX cycle of the N DRX cycles.

In the PDCCH monitoring method provided by the embodiment of the present disclosure, a PDCCH search space monitored by a terminal in an active time of each DRX cycle of N DRX cycles is determined based on a probability of traffic generation and/or an amount of traffic generation in the active time of each DRX cycle.

For example, the DRX cycle active time with a low probability of traffic occurrence may correspond to a PDCCH search space with a low number of blind tests, and the DRX cycle active time with a high probability of traffic occurrence may correspond to a PDCCH search space with a high number of blind tests.

In the PDCCH monitoring method provided by the embodiment of the present disclosure, a terminal can monitor a corresponding PDCCH search space at an active time of each DRX cycle based on a search space monitored by an active time of the terminal carried in a signal in each DRX cycle.

For example, the monitoring period is 3 DRX periods, the signal carries the PDCCH search space 2 monitored by the terminal at the active time of the first DRX period, the PDCCH search space 3 monitored at the active time of the second DRX period, and the PDCCH search space 1 monitored at the active time of the third DRX period, and then the terminal monitors the corresponding PDCCH search space at the active time of each DRX period based on the signal.

In the embodiment of the disclosure, the signal carries the PDCCH search space monitored by the active time of each DRX period in N DRX periods, and the terminal can determine the search space monitored by the active time of each DRX period based on the signal, so that the corresponding search space is monitored at the corresponding DRX period active time.

In the PDCCH monitoring method provided in the embodiments of the present disclosure, an active time corresponding to each DRX cycle in N DRX cycles is carried in a signal; or the signal carries the active time corresponding to each specific PDCCH search space monitoring period in the N specific PDCCH search space monitoring periods.

For example, the higher layer signaling configures M times of activity time (duration), where the M times of activity are different in duration, and the signal carries the activity time corresponding to each of the N DRX cycles or the specific PDCCH search space monitoring cycle.

In the PDCCH monitoring method provided in the embodiments of the present disclosure, a terminal monitors a PDCCH at an active time corresponding to each DRX cycle based on the active time corresponding to each DRX cycle in a signal; or monitoring the PDCCH at the active time corresponding to each specific PDCCH search space monitoring period based on the active time corresponding to each specific PDCCH search space monitoring period in the signal.

For example, the monitoring period is 3 DRX periods, the signal carries that the active time corresponding to the first DRX period is active time 2, the active time corresponding to the second DRX period is active time 1, and the active time corresponding to the third DRX period is active time 3, and then the terminal monitors the corresponding PDCCH at the active time corresponding to each DRX period based on the signal.

In the PDCCH monitoring method provided in the embodiments of the present disclosure, the active time corresponding to each DRX cycle or the active time corresponding to each specific PDCCH search space monitoring cycle is determined based on the probability of traffic generation and/or the traffic generation amount in each DRX cycle or each specific PDCCH search space monitoring cycle.

Illustratively, the active time of the DRX cycle with a lower traffic generation probability may be shorter, and the active time of the DRX cycle with a higher traffic generation probability may be longer. Alternatively, the active time of the DRX cycle with less traffic generation may be shorter and the active time of the DRX cycle with more traffic generation may be longer.

In the embodiment of the disclosure, the signal carries the active time corresponding to each DRX period or each specific PDCCH search space monitoring period, and the terminal can determine the active time corresponding to each DRX period or each specific PDCCH search space monitoring period based on the signal, so that the PDCCH is monitored in the corresponding DRX period or the specific PDCCH search space monitoring period with the corresponding active time.

Based on the same conception, the embodiment of the disclosure also provides a PDCCH monitoring method executed by the network device.

Fig. 4 is a flowchart illustrating a PDCCH monitoring method according to an exemplary embodiment, which is performed by a network device as shown in fig. 4, including the following steps.

In step S31, configuration information is transmitted, the configuration information being used to configure a monitoring period of a monitoring signal for the terminal.

In some embodiments, the network device may optionally configure the monitoring period for the terminal, or configure the monitoring period for the terminal based on some historical empirical value. For example, the network device may configure the monitoring period as N DRX periods or N specific PDCCH search space monitoring periods, N being a positive integer.

For example, when the discontinuous reception DRX cycle or the PDCCH search space monitoring cycle is 20ms and n=4, the monitoring cycle may be configured to 80ms, i.e., the terminal performs monitoring on the signal every 80 ms. And when the DRX cycle or PDCCH search space monitoring period is 20ms and n=5, the monitoring period may be configured to be 100ms, i.e., the terminal performs monitoring on the signal every 100 ms. Of course, it should be understood that the values of the discontinuous reception DRX cycle or PDCCH search space monitoring cycle length and N are only examples, and other possible values are also within the scope of the present invention.

In some embodiments, the signal may be PDCCH, or other physical channel, or some preset sequence, etc. The signal carries some information, the signal is used for indicating the monitoring time of the terminal for monitoring the PDCCH, and the terminal can acquire the information carried in the signal by monitoring the signal, so that the monitoring time for monitoring the PDCCH is determined.

Specifically, the signal can directly bear the monitoring time of the monitoring PDCCH, the terminal can directly determine the monitoring time of the monitoring PDCCH based on the signal, and at the moment, the monitoring time of the PDCCH can be determined by the terminal or the core network equipment and other equipment based on AI model prediction.

Or, the monitoring period configured by the configuration information for the terminal may be N DRX periods or N specific PDCCH search space monitoring periods, N bits may be carried in the signal, each bit corresponds to one DRX period or one specific PDCCH search space monitoring period, and the terminal may determine whether to monitor the PDCCH in the corresponding DRX period or the specific PDCCH search space monitoring period based on the bit value of each bit.

Or, the monitoring period configured by the configuration information for the terminal may be N DRX periods, and the signal may carry a PDCCH search space monitored by the terminal during an active time of each DRX period in the N DRX periods, where the terminal may be capable of monitoring a corresponding PDCCH search space during the active time of each DRX period based on the search space monitored by the terminal during the active time of each DRX period in the N DRX periods.

Or the monitoring period configured by the configuration information for the terminal can be N DRX periods or N specific PDCCH searching space monitoring periods, and the signal can bear the corresponding active time of each DRX period in the N DRX periods; or the signal carries the active time corresponding to each specific PDCCH search space monitoring period in N specific PDCCH search space monitoring periods, and the terminal can monitor the PDCCH at the active time corresponding to each DRX period based on the active time corresponding to each DRX period; or the terminal monitors the PDCCH at the active time corresponding to each specific PDCCH search space monitoring period based on the active time corresponding to each specific PDCCH search space monitoring period.

In the embodiment of the disclosure, the network device sends the configuration information, the configuration information is used for configuring the monitoring period of the monitoring signal for the terminal, and the signal is used for indicating the monitoring time of the terminal for monitoring the physical downlink control channel, so that the terminal can determine the monitoring time for monitoring the PDCCH based on the signal, and further the terminal can monitor the PDCCH at the corresponding monitoring time.

For example, the monitoring period of the terminal monitoring signal configured by the network device for the terminal is 20ms, and the signal carries the time when the terminal needs to monitor the PDCCH in 20ms, so that the terminal monitors the PDCCH at the corresponding time.

In some embodiments, the monitoring time for a terminal carried in the signal to monitor the PDCCH is determined based on AI model predictions. In one embodiment, the terminal determines the monitoring time of the PDCCH to be monitored based on AI model prediction and informs the network device, which configures the signal. In another embodiment, the core network device determines the monitoring time of the PDCCH to be monitored based on AI model prediction and informs the network device, which configures the signal.

Wherein the specific PDCCH search space is determined by the network device.
