Optionally, in this embodiment of the present application, the channel type of the target uplink transmission includes at least one of the following: Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), Physical Random Access Channel (Physical Random Access Channel, PRACH).

Step 102: In the first time period and the terminal sends the target uplink transmission according to the target configuration information, the terminal suspends or stops skipping PDCCH monitoring;

In the embodiment of the present application, the above-mentioned first time period includes the duration of skipping PDCCH monitoring and the first application delay. At least one item: the first application delay is the application delay of skipping PDCCH monitoring indication, and the skipping PDCCH monitoring indication is used to indicate the duration of skipping PDCCH monitoring.

In this embodiment of the present application, the terminal may receive a skip PDCCH monitoring instruction from a network side device, and according to the skip PDCCH monitoring instruction, skip PDCCH monitoring within the duration of skipping PDCCH monitoring.

It can be understood that, in a possible implementation manner of the embodiment of the present application, skipping PDCCH monitoring is equivalent to not performing PDCCH monitoring; and pausing or stopping skipping PDCCH monitoring is equivalent to resuming PDCCH monitoring, or pausing or stopping skipping PDCCH monitoring. Over-PDCCH monitoring and resumption of PDCCH monitoring occur simultaneously. Therefore, if the following involves suspending or stopping skipping PDCCH monitoring, this understanding will be followed and will not be described again.

In this embodiment of the present application, there is no strong correlation between the above step 101 and step 102, that is, step 101 can only be used to configure the above target uplink transmission. After obtaining some configurations of the target uplink transmission, the terminal can send the target uplink transmission according to specific situations or specific conditions.

In a possible implementation manner of the embodiment of the present application, the terminal can choose whether to send the target uplink transmission at the configured target uplink transmission opportunity according to certain trigger conditions. In other words, the terminal may or may not send target uplink transmission. For example, the certain triggering condition may be that the terminal determines whether to send the target uplink transmission based on whether there is uplink data to be transmitted or with a higher transmission priority waiting to be sent, so as to suspend or stop skipping PDCCH monitoring. For another example, the certain trigger condition includes: when the first time period includes the duration of skipping PDCCH monitoring, the terminal can determine whether the duration of skipping PDCCH monitoring is based on the length of the duration of skipping PDCCH monitoring. Send target upstream transmission within. For another example, the certain trigger condition includes: when the first time period includes the first application delay, the terminal determines whether to send the target uplink transmission within the first application delay. The embodiments of the present application are not limited here.

For example, in the case where the first time period includes the first application delay, the terminal may be restricted from sending the target uplink transmission within the first application delay.

Optionally, in this embodiment of the present application, uplink transmissions other than target uplink transmissions will not trigger suspension or stop skipping PDCCH monitoring.

Optionally, in this embodiment of the present application, when the first time period is the first application delay, the terminal may ignore (or not ignore) the uplink transmission within the first application delay according to the transmission target. ) An indication of skip PDCCH monitoring indication corresponding to the first application delay.

Further optionally, in the embodiment of the present application, after the above step 101, the PDCCH monitoring method provided by the embodiment of the present application may further include the following step 201.

Step 201: If the terminal sends target uplink transmission within the first application delay, the terminal performs the target operation.

Wherein, the above target operation includes any of the following: canceling the application skip PDCCH monitoring instruction, skipping PDCCH monitoring within the duration of skipping PDCCH monitoring.

In the embodiment of the present application, if the target operation is to cancel the application of skipping PDCCH monitoring indication, it can be considered that the terminal ignores the indication of skipping PDCCH monitoring indication corresponding to the first application delay.

If the target operation is to skip PDCCH monitoring within the duration of skipping PDCCH monitoring, it can be considered that the terminal does not ignore the indication of skipping PDCCH monitoring indication corresponding to the first application delay, that is, it does not affect the effect that takes effect after the first application delay. The duration of skipping PDCCH monitoring.

In an example, when the first time period includes a duration of skipping PDCCH monitoring, the duration of skipping PDCCH monitoring is greater than or equal to a preset duration.

For example, the duration of skipping PDCCH monitoring is greater than or equal to 20 ms. Further, if the duration of skipping PDCCH monitoring is less than 20 ms, the terminal may send the target uplink transmission within the duration of skipping PDCCH monitoring.

It can be understood that if the duration of skipping PDCCH monitoring is greater than or equal to the preset duration, the terminal can send the target uplink transmission within the duration of skipping PDCCH monitoring.

Optionally, in this embodiment of the present application, the above-mentioned preset time length may specifically be: configured by the network side device or agreed upon by the protocol.

It can be seen that, since the duration of skipping PDCCH monitoring is greater than or equal to the preset duration, the terminal can send the target uplink transmission within the duration of skipping PDCCH monitoring to suspend or stop skipping PDCCH monitoring. Therefore, it is possible to avoid an increase in data transmission delay caused by a long skipped PDCCH monitoring duration, and improve data transmission performance.

In another example, the PDCCH monitoring method provided by the embodiment of the present application may further include (1).

(1) If the duration of skipping PDCCH monitoring is not greater than or equal to the preset duration, the terminal will not send the target uplink transmission within the duration of skipping PDCCH monitoring.

It can be understood that if the duration of skipping PDCCH monitoring is less than the preset duration, the terminal cannot send the target uplink transmission within the duration of skipping PDCCH monitoring.

In the embodiment of this application, the above "terminal suspends and skips PDCCH monitoring" can be understood as: the terminal resumes PDCCH monitoring first, and has the opportunity to subsequently resume this time skipping PDCCH monitoring. The above "terminal stops skipping PDCCH monitoring" can be understood as: the terminal resumes PDCCH monitoring and cannot resume skipping PDCCH monitoring this time. Instead, the PDCCH skipping monitoring instruction can only be received again subsequently, and then a new PDCCH skipping monitoring can be performed according to the PDCCH skipping monitoring instruction.

An example will be given below to illustrate when the terminal pauses or stops skipping PDCCH monitoring.

Optionally, in this embodiment of the present application, the above terminal suspends or stops skipping PDCCH monitoring, including at least one of the following:

The terminal pauses or stops skipping PDCCH monitoring at the end of the time unit in which the target uplink transmission is sent;

The terminal pauses or stops skipping PDCCH monitoring at the starting moment of the first time unit after sending the target uplink transmission;

The terminal pauses or stops skipping PDCCH monitoring at the starting moment of the first specific time unit after sending the target uplink transmission;

The terminal suspends or stops skipping PDCCH monitoring after the first time interval from the end of the time unit in which the target uplink transmission is sent.

The above time unit may include any of the following: slots, Orthogonal Frequency Division Multiplexing (OFDM) symbols, subframes, etc.

In a possible implementation manner of the embodiment of this application, in the first time period and the terminal sends the target uplink transmission, the terminal is at the starting position of the next time unit after the time unit in which the target uplink transmission is sent. , pause or stop skipping PDCCH monitoring.

In the embodiment of this application, the above-mentioned specific time unit includes at least one of the following:

There are downlink time units with PDCCH monitoring opportunities;

Semi-static downlink time unit;

Non-uplink time unit;

Non-semi-static upstream time unit.

Optionally, in this embodiment of the present application, the above-mentioned first time interval may specifically be: configured by the network side device or agreed upon by the protocol.

It can be understood that the semi-static uplink time unit is the uplink time unit configured by high-level signaling on the network side rather than that configured by DCI.

In the embodiment of this application, since the network side device requires a certain amount of processing time for data detection and demodulation, the terminal can pause or stop after the first time interval from the end of the time unit in which the target uplink transmission is completed. Skip PDCCH monitoring.

Optionally, in this embodiment of the present application, the terminal skips PDCCH monitoring in the first time interval starting from the end of the time unit in which the target uplink transmission is sent.

For example, as shown in Figure 3, assume that the duration of skipping PDCCH monitoring indicated by the skip PDCCH monitoring indication is 10 milliseconds (ms). During the duration of skipping PDCCH monitoring, the terminal can use the PUSCH resource configured by the higher layer. The target uplink transmission (such as BSR) is sent to the network side device, and the terminal can continue to skip PDCCH monitoring in the first time interval after sending the BSR, and at the end of the first time interval, the terminal pauses or stops skipping PDCCH monitoring means resuming PDCCH monitoring.

According to the PDCCH monitoring method provided by the embodiment of the present application, the terminal can obtain the target configuration information of the target uplink transmission, and within the first time period (that is, skipping at least one of the duration of PDCCH monitoring and the first application delay) and the terminal When sending target uplink transmission according to the target configuration information, the terminal can suspend or stop skipping PDCCH monitoring; wherein the first application delay is the application delay of skipping PDCCH monitoring indication, and the skipping PDCCH monitoring indication is used to indicate Skip the duration of PDCCH monitoring. Since within the duration of skipping PDCCH monitoring (and/or the first application delay), the terminal can send target uplink transmission according to the target configuration information to suspend or stop skipping PDCCH monitoring, that is, to resume PDCCH monitoring, therefore, it can This avoids the increase in data transmission delay caused by skipping PDCCH monitoring, thereby improving data transmission performance.

An example will be given below to illustrate how the terminal suspends skipping PDCCH monitoring and/or resumes suspended skipping PDCCH monitoring.

Optionally, in this embodiment of the present application, as shown in Figure 4 in conjunction with Figure 2, the above step 102 can be specifically implemented through the following step 102a.

Step 102a: If the terminal sends the target uplink transmission according to the target configuration information within the first time period, the terminal suspends and skips PDCCH monitoring in the second time period.

Further optionally, in this embodiment of the present application, the above-mentioned second time period may specifically be: configured by the network side device or agreed upon by the protocol.

Optionally, in this embodiment of the present application, the above-mentioned step 102a may be specifically implemented through the following step 102a1 and/or step 102a2.

Step 102a1: The terminal suspends and skips PDCCH monitoring in response to the target uplink transmission within the second time period.

Step 102a2: The terminal pauses and skips the specific type of PDCCH monitoring in the second time period.

In a possible implementation manner of the embodiment of this application, the target uplink transmission is SR, and the PDCCH used to respond to the SR is the PDCCH allocated the uplink scheduling grant ULgrant. Therefore, in the first time period and when the terminal sends an SR according to the target configuration information, the terminal suspends and skips the PDCCH monitoring for responding to the SR in the second time period (that is, the PDCCH monitoring for which the uplink scheduling grant ULgrant is allocated).

Further optionally, in the embodiment of this application, the specific type of PDCCH includes: Type3-PDCCH CSS sets At least one of the corresponding PDCCH and the PDCCH corresponding to the USS set.

Optionally, in this embodiment of the present application, the above step 102a may be specifically implemented through the following step 102a3.

Step 102a3: The terminal pauses and skips PDCCH monitoring in the third time period.

In the embodiment of the present application, the above-mentioned third time period is: a time period in which the duration of skipping PDCCH monitoring overlaps with the second time period.

It can be understood that if the second time period overlaps with the duration of skipped PDCCH monitoring, then the skipped PDCCH monitoring is suspended during the overlap time period (ie, the third time period).

Optionally, in this embodiment of the present application, as shown in Figure 5 in conjunction with Figure 4, after the above step 102a, the PDCCH monitoring method provided by the embodiment of the present application may also include the following step 301, or step 302, or step 303.

Step 301: The terminal resumes skipping PDCCH monitoring.

Further optionally, in this embodiment of the present application, after the terminal suspends skipping PDCCH monitoring in the third time period, the terminal can directly resume skipping PDCCH monitoring.

It can be understood that after the overlap period, the terminal can continue to skip PDCCH monitoring.

It can be seen that since the terminal can directly resume skipping PDCCH monitoring instead of continuously performing PDCCH monitoring, the power consumption of the terminal can be saved.

Step 302: If the terminal does not receive the PDCCH within the second time period, the terminal resumes skipping PDCCH monitoring.

In this embodiment of the present application, the terminal may resume skipping PDCCH monitoring at the end of the second time period.

Optionally, in a possible implementation manner of the embodiment of this application, the duration for resuming skipped PDCCH monitoring is: specified by the network side device configuration or protocol.

For example, the time period for resuming PDCCH monitoring is configured by the network side, and the duration of the time period for resuming PDCCH monitoring is 3 ms.

Optionally, in another possible implementation manner of the embodiment of the present application, the duration for resuming skipped PDCCH monitoring is any one of the following: a first duration or a second duration.

In the embodiment of this application, the above-mentioned first duration is: when the terminal suspends skipping PDCCH monitoring, the remaining duration of skipping PDCCH monitoring; the above-mentioned second duration is determined by the first duration and the duration of the second time period. .

For example, assume that the duration of resuming skipping PDCCH monitoring is the first duration, the duration of skipping PDCCH monitoring is 10 ms, and the terminal suspends skipping PDCCH monitoring within the second time period (for example, 4ms to 6ms); then The duration for resuming skipped PDCCH monitoring is the remaining duration of the duration of skipped PDCCH monitoring when the terminal pauses skipped PDCCH monitoring (that is, 4ms), that is, 6ms.

As another example, assume that the duration of resuming skipping PDCCH monitoring is the second duration, the duration of skipping PDCCH monitoring is 10 ms, and the terminal suspends skipping PDCCH monitoring within the second time period (for example, 4ms to 6ms); Then the duration of resuming skipping PDCCH monitoring is the difference between the first duration and the duration of the second time period, where the first duration is 6ms and the duration of the second time period is 2ms. The duration of resuming skipping PDCCH monitoring is The duration length is 6ms-2ms=4ms.

It can be seen from this that since the terminal can resume skipping PDCCH monitoring when it does not receive a PDCCH within the time period of suspending PDCCH monitoring instead of continuously performing PDCCH monitoring, therefore the power consumption of the terminal can be saved.

Step 303: If the terminal does not receive the target PDCCH within the second time period, the terminal resumes skipping PDCCH monitoring.
