As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0045] The following, in combination with the accompanying drawings, describes in detail the PDCCH monitoring control method, apparatus, terminal, network side equipment and medium provided in the embodiments of the present application through some embodiments and their application scenarios.

[0046] Currently, the network energy saving project is standardizing the cell DTX / DRX mechanism. First, the cell DTX / DRX parameters can be explicitly configured to the base station through the base station. The parameters at least include periodicity, startslot / offset, and on duration. Through this configuration, each cycle time is divided into two parts: active period and non-active period. During the active period, the base station can send and receive normally; during the non-active period, the base station can stop sending or receiving specific signals and channels to achieve the purpose of network energy saving.

[0047] The cell DTX configuration and the cell DRX configuration may be configured together or independently. At the same time, the Cell DTX / DRX configuration may be activated / deactivated through Radio Resource Control (RRC) or through Downlink Control Information (DCI).

[0048] In summary, cell DTX / DRX will not affect the transmission of random access channel (RACH), paging or reception of system information blocks (SIBs). During the Cell DTX non-active period, the terminal does not need to monitor the semi-static scheduling opportunity, but the behavior of monitoring the PDCCH corresponding to the random access response (RAR) / message (Msg) 4 is not affected; during the Cell DRX non-active period, the terminal does not send a configured grant (CG) and will not send an SR on the Scheduling Request (SR) opportunity that overlaps with the non-active period.

[0049] PDCCH skipping is a method to achieve energy saving. It can skip PDCCH monitoring for a certain period of time through the PDCCH skipping indication in the DCI. The network-side device can tell the terminal how long PDCCH demodulation should be skipped through RRC configuration. For example, the PDCCH skipping DCI indicates to skip PDCCH monitoring in the next 4, 8, or 16 time slots or ms. Skipping monitoring means not monitoring, but it should be noted that skipping PDCCH for a period of time refers to skipping the first type of PDCCH for a period of time. The first type of PDCCH can be the PDCCH corresponding to Type3-PDCCH CSS sets or USS sets.

[0050] There are two types of terminal behaviors corresponding to the indication bits of PDCCH skipping indication. One type is when the bit value is all zero, and the corresponding terminal behavior is not to perform PDCCH skipping. The other type is when the bit value is not all zero, and the corresponding terminal behavior is to skip monitoring of PDCCH (PDCCH corresponding to Type3-PDCCH CSS sets or USS sets) within a specific time interval. In the DCI message, the network tells the terminal which duration value should be selected through PDCCH monitoring adaptation indication.

[0051] However, the terminal cannot perform PDCCH skipping in the following cases:

[0052] 1. SR is being sent or has just been sent;

[0053] 2. During random access, the contention resolution timer is running;

[0054] 3. During random access, while waiting for RAR.

[0055] Among them, if the terminal sends an SR after receiving the DCI (skipping PDCCH monitoring), the terminal will resume PDCCH monitoring from the last symbol of the physical uplink control channel (PUCCH) transmitted by the SR; within the RAR / MsgB receiving window, PDCCH skipping can still be applied to Type3 PDCCH CSS and will not affect RAR / MsgB reception, because the PDCCH type monitored when receiving RAR / MsgB is Type 1CSSDCI; the transmission of channel state information (Channel State Information, CSI) and SRS will not be affected by PDCCH skipping, that is, CSI / SRS will still be transmitted within the skipping duration; PDCCH skipping is only applied to the terminal C-DRX active time.

[0056] In summary, it has been concluded that when cell DTX is non-active, even if the terminal is in the active time of C-DRX, the terminal will not perform PDCCH monitoring. However, during the cell DTX non-active period, if the terminal has a higher priority service that needs to be scheduled, or when the terminal feedbacks NACK, it can only wait until the next cellDTX active period to schedule, which will inevitably bring a large delay. Since the terminal can only follow the existing rules and not perform PDCCH monitoring during the non-active period of cell DTX, and perform PDCCH monitoring during the active period of cell DTX, the flexibility of the terminal in performing PDCCH monitoring is poor.

[0057] In order to solve the above problems, the embodiments of the present application provide a PDCCH monitoring control method, apparatus, terminal, network-side equipment and medium. The PDCCH monitoring control method provided by the embodiments of the present application can be applied in the PDCCH monitoring scenario.

[0058] In the PDCCH monitoring control method provided in the embodiment of the present application, the terminal can receive the first configuration information sent by the network side device, the first configuration information indicates the related behavior of at least one of the cell DTX and the cell DRX of the network side device; and can perform a first operation based on the first configuration information, the first operation is an operation of changing the PDCCH monitoring behavior. Through this scheme, since the terminal can perform the operation of changing the PDCCH monitoring behavior according to the related configuration of at least one of the cell DTX and the cell DRX of the network side device, it is not necessary to determine whether to perform PDCCH monitoring according to whether the cell is in the DTX activation period according to the existing rules, thereby improving the flexibility of the terminal in performing PDCCH monitoring.

[0059] The present application provides a PDCCH monitoring control method. Figure 2 FIG. 1 is a flow chart showing a PDCCH monitoring control method provided by an embodiment of the present application. Figure 2 As shown, the PDCCH monitoring control method provided in the embodiment of the present application may include the following steps 201 and 202.

[0060] Step 201: A terminal receives first configuration information sent by a network-side device.

[0061] The first configuration information indicates a related behavior of at least one of the cell DTX and the cell DRX of the network side device.

[0065] Step 202: The terminal performs a first operation based on the first configuration information.

[0066] The first operation is an operation of changing the PDCCH monitoring behavior.

[0067] Optionally, in the embodiment of the present application, the first operation may include any one of the following 1.1 to 1.10:

[0068] 1.1. Resume monitoring of a specific type of PDCCH;

[0069] 1.2. Resume monitoring of all types of PDCCH;

[0070] 1.3. Stop monitoring a specific type of PDCCH;

[0073] 1.6. Stop PDCCH search space group switching;

[0074] 1.7. Stop the timer for switching the PDCCH search space group;

[0075] 1.8. Restart the timer for switching the PDCCH search space group;

[0076] 1.9. Suspend the timer for switching the PDCCH search space group;

[0077] 1.10. Restore the timer for switching the PDCCH search space group.

[0078] Optionally, in an embodiment of the present application, the above-mentioned specific type of PDCCH may be a PDCCH corresponding to Type3-PDCCH CSS sets or USS sets.

[0079] Optionally, in an embodiment of the present application, the above-mentioned PDCCH search space group switching timer (ie, searchSpaceSwitchTimer) is located in PDCCH-ServingCellConfig-IE.

[0080] In the embodiment of the present application, since the above-mentioned first operation may include any one of the above-mentioned 1.1 to 1.10, the terminal may perform different operations of changing the PDCCH monitoring behavior based on the above-mentioned first configuration information, thereby improving the flexibility of PDCCH monitoring.

[0081] In the PDCCH monitoring control method provided in the embodiment of the present application, since the terminal can perform the operation of changing the PDCCH monitoring behavior according to the relevant configuration of at least one of the cell DTX and the cell DRX of the network side device, there is no need to determine whether to perform PDCCH monitoring according to whether the cell is in the DTX activation period according to the existing rules, thereby improving the flexibility of the terminal in performing PDCCH monitoring.

[0082] Optionally, in an embodiment of the present application, before the above step 202, the PDCCH monitoring control method provided by the embodiment of the present application may further include the following step 203.

[0083] Step 203: The terminal performs a first uplink transmission.

[0084] The first uplink transmission includes at least one of the following:

[0090] Transmission of the first PUSCH, where the first PUSCH is used to transmit at least one of the following: a specific type of CG, a specific type of buffer status report (Buffer Status Report, BSR), and uplink data of a specific service type.

[0091] Optionally, in the embodiment of the present application, the uplink data of the above-mentioned specific service type may include uplink data of emergency services.

[0092] Optionally, in the embodiment of the present application, the first PUSCH may include any one of the following 2.1 to 2.7:

[0093] 2.1. PUSCH with a specified configuration identifier (i.e., config index);

[0094] 2.2. PUSCH with specified physical layer priority (i.e. PHY priority);

[0097] 2.5. PUSCH carrying uplink control information (UCI);

[0098] 2.6, PUSCH carrying CG-UCI;

[0099] 2.7. PUSCH carrying BSR information.

[0100] In the embodiment of the present application, since the first PUSCH may include any one of 2.1 to 2.7, the flexibility of the first uplink transmission performed by the terminal before performing the first operation may be improved.

[0101] Optionally, in the embodiment of the present application, the above step 202 can be specifically implemented by the following step 202a.

[0102] Step 202a: The terminal performs a first operation at a first moment based on the first configuration information.

[0103] The first moment mentioned above includes any of the following:

[0104] The start time of the DTX inactive period of the cell;

[0105] The start time of the DTX activation period of the cell;

[0106] An end time of a time unit in which a first DCI is received, where the first DCI is a DCI detected by the terminal and carries a PDCCH monitoring adaptation field;

[0107] The starting time of the first time unit after the terminal performs the first uplink transmission;

[0108] The starting time of the first specific time unit after the terminal performs the first uplink transmission, the first specific time unit being: the first downlink time unit, or the first downlink time unit having a PDCCH monitoring occasion (ie, PDCCH monitoringoccasion);

[0109] a start time of a target time unit, the target time unit being: a time unit separated by a first time interval from an execution end time of the first uplink transmission;

[0110] When the terminal finishes executing the first uplink transmission, the first timer started times out.

[0111] Optionally, in an embodiment of the present application, the first moment may be a moment determined by the terminal according to the first configuration information.

[0112] Optionally, in an embodiment of the present application, the above-mentioned time unit may be a time slot, a symbol or a subframe, etc.

[0113] It should be noted that the embodiments of the present application illustrate that the granularity of the time unit is different from the granularity of the moment. In actual implementation, the granularity of the time unit and the granularity of the moment can be the same. In this case, the start / end moment of the time unit is the time unit itself.

[0114] Optionally, in the embodiment of the present application, the first time interval may be any time interval that is preconfigured, predefined, or agreed upon by a protocol.

[0115] Optionally, in an embodiment of the present application, when the first moment is when the terminal finishes executing the first uplink transmission and the first timer started times out, the terminal can start the first timer after executing the first uplink transmission, so that the network side device can determine during the first timer whether to send the downlink transmission corresponding to the first uplink transmission after the first timer times out; that is, the time corresponding to the first timer is the time for the network side device to prepare the downlink transmission corresponding to the first uplink transmission; that is, the terminal can understand that only after the time corresponding to the first timer is exceeded, the network side device can perform the downlink transmission corresponding to the first uplink transmission.

[0116] Optionally, in an embodiment of the present application, the first timer may be preconfigured, predefined or agreed upon by protocol, or the first timer may be arbitrarily set according to actual usage requirements.

[0117] Optionally, in an embodiment of the present application, during the above-mentioned first timer, if the network side device finds that the number of the above-mentioned first uplink transmissions is large, it will send a corresponding downlink transmission, such as PDCCH, after the first timer expires; if the network side device finds that the number of the first uplink transmissions is not enough for the network side device to activate, the network side device does not need to send the corresponding downlink transmission.

[0118] For example, Figure 3 As shown, after executing the above-mentioned first uplink transmission, the terminal starts the above-mentioned first timer, and does not perform PDCCH monitoring during the first timer; during the first timer, the network side device finds that the number of the first uplink transmissions is large, and the network side device will send the corresponding downlink transmission after the first timer expires, such as PDCCH, so that the terminal can resume PDCCH monitoring (i.e., the above-mentioned first operation) when the first timer times out (i.e., the above-mentioned first moment), and promptly receive the downlink transmission sent by the network side device.

[0119] Optionally, in an embodiment of the present application, when the above-mentioned first moment is the starting moment of entering the inactive period of the above-mentioned cell DTX, the terminal may perform the above-mentioned first operation at the first moment, and starting from the active period of the cell DTX most recently after the first moment, monitor the PDCCH during the active period of the cell DTX, and stop monitoring the PDCCH during the inactive period of the cell DTX.

[0120] Optionally, in an embodiment of the present application, when the above-mentioned first moment is the starting moment of entering the activation period of the above-mentioned cell DTX, the terminal can perform the above-mentioned first operation at the first moment, and starting from the inactive period of the cell DTX most recently after the first moment, stop monitoring PDCCH during the inactive period of the cell DTX, and monitor PDCCH during the active period of the cell DTX.

[0121] Optionally, in an embodiment of the present application, when the above-mentioned first moment is the end moment of the time unit for receiving the above-mentioned first DCI, the terminal may perform the above-mentioned first operation at the first moment, and when the first moment is within the activation period of the cell DTX, starting from the inactive period of the cell DTX most recently after the first moment, stop monitoring the PDCCH during the inactive period of the cell DTX, and monitor the PDCCH during the active period of the cell DTX; when the first moment is within the inactive period of the cell DTX, starting from the active period of the cell DTX most recently after the first moment, monitor the PDCCH during the active period of the cell DTX, and stop monitoring the PDCCH during the inactive period of the cell DTX.

[0122] Optionally, in an embodiment of the present application, the terminal may perform any possible first operation at different first moments.

[0123] For example, if the above-mentioned first moment is the starting moment of entering the non-activation period of the above-mentioned cell DTX, or the starting moment of the first time unit after the terminal executes the above-mentioned first uplink transmission, or the starting moment of the first specific time unit after the terminal executes the first uplink transmission, or the starting moment of the above-mentioned target time unit, or the end moment of the above-mentioned first timer, then the above-mentioned first operation can be 1.1, 1.2, 1.5, 1.8, 1.9 or 1.10.

[0124] For another example, if the first moment is the start moment of entering the activation period of the DTX of the cell, the first operation may be 1.3, 1.4, 1.6 or 1.7.

[0125] For another example, if the first moment is the end moment of the time unit in which the first DCI is received, the first operation may be any one of 1.1 to 1.10.

[0126] It should be noted that the first operation performed by the terminal at different first moments can be determined according to actual usage requirements, and is not limited in the embodiments of the present application.

[0127] In the embodiment of the present application, since the terminal can perform the first operation at different first moments based on the first configuration information, the flexibility of the terminal in performing the first operation can be improved.

[0128] Optionally, in an embodiment of the present application, the first moment is related to the first uplink transmission, and the first operation includes resuming monitoring of a first PDCCH, where the first PDCCH is a specific type of PDCCH or all types of PDCCHs. Exemplarily, the step 202a can be implemented by the following step 202a1.

[0129] Step 202a1: Based on the first configuration information, the terminal resumes monitoring the first PDCCH at a first moment, and stops monitoring the first PDCCH at a second moment.

[0130] The second moment is: the end moment of the first activation period of the DTX of the cell after the first moment; or the end moment of the first non-activation period of the DTX of the cell after the first moment.

[0131] Optionally, in an embodiment of the present application, the above-mentioned first moment is related to the above-mentioned first uplink transmission, that is, the first moment includes any one of the following items: the starting moment of the first time unit after the terminal executes the above-mentioned first uplink transmission; the starting moment of the first specific time unit after the terminal executes the first uplink transmission; the starting moment of the above-mentioned target time unit; when the first timer started by the terminal when the terminal finishes executing the first uplink transmission times out.

[0132] Optionally, in an embodiment of the present application, the first moment may be a moment at which execution of the first uplink transmission ends.

[0133] For example, Figure 4 As shown, based on the first configuration information, the terminal starts to resume monitoring the first PDCCH at the end time of the execution of the first uplink transmission (i.e., the first time), and stops monitoring the first PDCCH at the end time of the activation period of the first cell DTX (i.e., DTX ON) (i.e., the second time) after the end time of the execution of the first uplink transmission.

[0134] Optionally, in an embodiment of the present application, after the terminal stops monitoring the first PDCCH at the second moment, it continues to follow the existing rules and does not monitor the first PDCCH during the inactive period of DTX, and monitors the first PDCCH during the active period of DTX.

[0135] In an embodiment of the present application, since the terminal can resume monitoring the first PDCCH at the first moment based on the first configuration information and stop monitoring the first PDCCH at the second moment, it is possible to perform PDCCH monitoring during the non-activation period of DTX, thereby further improving the flexibility of the terminal in performing PDCCH monitoring and reducing the downlink data transmission delay.

[0136] Optionally, in an embodiment of the present application, the first moment is related to the first uplink transmission, and the first operation includes resuming monitoring of a first PDCCH, where the first PDCCH is a specific type of PDCCH or all types of PDCCHs. Exemplarily, the step 202a can be implemented by the following step 202a2.

[0137] Step 202a2: Based on the first configuration information, the terminal starts the second timer at the first moment and starts to resume monitoring the first PDCCH, and determines whether to stop monitoring the first PDCCH according to the first rule when the second timer times out.

[0138] The first rule mentioned above includes:

[0139] If the second timer times out during the inactive period of the DTX of the cell, the terminal stops monitoring the first PDCCH when the second timer times out;

[0140] If the second timer times out during the activation period of the cell DTX, the terminal keeps monitoring the first PDCCH when the second timer times out.

[0141] Optionally, in an embodiment of the present application, the first moment may be a moment at which execution of the first uplink transmission ends.

[0142] Optionally, in an embodiment of the present application, the second timer may be used to specify the duration for which the terminal resumes PDCCH monitoring, thereby avoiding excessively long useless monitoring.

[0143] Optionally, in an embodiment of the present application, the second timer may be preconfigured, predefined or agreed upon by protocol, or the second timer may be arbitrarily set according to actual usage requirements.

[0144] Optionally, in an embodiment of the present application, the second timer is different from the first timer; the second timer is started immediately after the terminal executes the first uplink transmission, and the terminal also immediately monitors PDCCH. Compared with the second timer, the terminal starts to resume monitoring PDCCH after the first timer times out, so that the first timer can minimize the time for the terminal to monitor PDCCH.

[0145] For example, Figure 5 As shown, based on the first configuration information, the terminal starts the second timer at the end time of the execution of the first uplink transmission (i.e., the first time) and starts to resume monitoring the first PDCCH, but the second timer times out during the non-active period of DTX in the cell (i.e., DTX OFF), so that the terminal can follow the behavior in the DTX non-active period and stop monitoring the first PDCCH when the second timer times out.

[0146] As another example, Figure 6 As shown, based on the first configuration information, the terminal starts the second timer at the end time of the execution of the first uplink transmission (i.e., the first time) and starts to resume monitoring the first PDCCH, but the second timer times out during the activation period of the DTX of the cell (i.e., DTX ON), so that the terminal can follow the behavior within the DTX activeperiod and keep monitoring the first PDCCH when the second timer times out.

[0147] Optionally, in an embodiment of the present application, after the terminal determines whether to stop monitoring the first PDCCH according to the first rule, it may, according to existing rules, not monitor the first PDCCH during the inactive period of DTX, and monitor the first PDCCH during the active period of DTX.

[0148] In an embodiment of the present application, since the terminal can start the second timer at the first moment and begin to resume monitoring the first PDCCH based on the first configuration information, and when the second timer times out, determine whether to stop monitoring the first PDCCH according to the first rule, the flexibility of the terminal in monitoring PDCCH can be further improved.

[0149] Optionally, in an embodiment of the present application, the first moment is related to the first uplink transmission, and the first operation includes resuming monitoring of a first PDCCH, where the first PDCCH is a specific type of PDCCH or all types of PDCCHs. Exemplarily, the step 202a can be implemented by the following step 202a3.

[0150] Step 202a3: Based on the first configuration information, the terminal starts the third timer at the first moment and starts to resume monitoring the first PDCCH, and stops monitoring the first PDCCH according to the second rule.

[0151] The time length of the third timer is less than the time length of the inactive period of the cell DTX, and the second rule includes:

[0152] If the downlink transmission corresponding to the first uplink transmission is not received before the third timer times out, the terminal stops monitoring the first PDCCH when the third timer times out;

[0153] If the downlink transmission corresponding to the first uplink transmission is received before the third timer times out, the terminal stops monitoring the first PDCCH at the moment of receiving the downlink transmission corresponding to the first uplink transmission.

[0154] Optionally, in an embodiment of the present application, the first moment may be a moment at which execution of the first uplink transmission ends.

[0155] Optionally, in an embodiment of the present application, the third timer may be used to terminate the PDCCH monitoring of the terminal as early as possible, thereby further avoiding useless monitoring.

[0156] Optionally, in an embodiment of the present application, the third timer may be preconfigured, predefined or agreed upon by protocol, or the third timer may be arbitrarily set according to actual usage requirements.

[0157] Optionally, in an embodiment of the present application, the third timer may be different from both the first timer and the second timer. Compared with the second timer, the third timer may stop PDCCH monitoring upon receiving the downlink transmission corresponding to the first uplink transmission, and the duration of stopping PDCCH monitoring may be longer.

[0158] For example, Figure 7As shown, based on the first configuration information, the terminal starts the third timer at the end time of the execution of the first uplink transmission (i.e., the first time) and starts to resume monitoring the first PDCCH, and receives the downlink transmission corresponding to the first uplink transmission before the third timer expires, so that the terminal can stop monitoring the first PDCCH at the moment of receiving the downlink transmission corresponding to the first uplink transmission.

[0159] Optionally, in an embodiment of the present application, after the terminal stops monitoring the first PDCCH according to the second rule, it may, according to existing rules, not monitor the first PDCCH during the inactive period of DTX, and monitor the first PDCCH during the active period of DTX.

[0160] In an embodiment of the present application, since the terminal can start the third timer at the first moment and start to resume monitoring the first PDCCH based on the first configuration information, and if the downlink transmission corresponding to the first uplink transmission is not received before the third timer expires, the terminal stops monitoring the first PDCCH at the end moment of the third timer, or if the downlink transmission corresponding to the first uplink transmission is received before the third timer expires, the terminal stops monitoring the first PDCCH at the moment of receiving the downlink transmission, thereby further improving the flexibility of the terminal in monitoring PDCCH.

[0161] The PDCCH monitoring control method provided in the embodiment of the present application is exemplarily described below in conjunction with the accompanying drawings.

[0162] For example, assume that the terminal detects a DCI providing a PDCCH monitoring adaptation field, and the filed indicates to skip PDCCH monitoring on the activated downlink BWP of the serving cell; if the terminal sends a PUSCH or PUCCH carrying NACK during the cell DTX non-active period, then Figure 8 As shown, the terminal terminates PDCCH skipping and resumes PDCCH monitoring from the last symbol of the PUCCH or PUSCH carrying the NACK.

[0163] As another example, assume that the terminal detects a DCI providing a PDCCH monitoring adaptation field, and the filed indicates to skip PDCCH monitoring on the activated downlink BWP of the serving cell; if the terminal sends a PUSCH or PUCCH carrying NACK during the cell DTXactive period, then Figure 9aAs shown, the terminal resumes PDCCH monitoring within the DTX active period starting from the last symbol of the PUCCH or PUSCH carrying the NACK.

[0164] It can be seen that in Figure 9a In the example, since the terminal is configured with C-DRX, the terminal will automatically terminate PDCCH skipping after NACK transmission (i.e., the first uplink transmission mentioned above) and resume PDCCH monitoring; however, if the terminal is not configured with C-DRX, Figure 9b As shown, the terminal resumes PDCCH monitoring after NACK transmission, and stops PDCCH monitoring once entering the DTX OFF period. Obviously, the duration of resuming PDCCH monitoring through the first uplink transmission is limited, and it cannot monitor endlessly, so at the most recent DTX OFF moment (i.e. the first moment mentioned above), the PDCCH monitoring (i.e. the first operation mentioned above) is stopped.

[0165] In summary, when receiving the PDCCH monitoring adaptation indication, the terminal resumes PDCCH monitoring by sending NACK / SR until the start time of the most recent DTX OFF (cell DTX non-active period).

[0166] Optionally, in the embodiment of the present application, if the first configuration information does not configure cell DRX (ie, only cell DTXwithout UE DRX), the terminal will not enter the discontinuous reception state, that is, the terminal will continue to monitor the PDCCH.

[0167] For example, when the first uplink transmission is in the DTX non-active period, under the existing mechanism, in the DTX OFF period, the terminal will not monitor the PDCCH, so the PDCCH corresponding to the retransmission or new transmission will not be monitored; and in the PDCCH monitoring control method provided in the embodiment of the present application, Fig.10 As shown, the terminal can resume PDCCH monitoring in the next symbol after NACK is sent (ie, the first uplink transmission), that is, from the start of NACK transmission to the end of the DTX OFF period where the NACK is transmitted, the terminal can continuously monitor PDCCH to monitor retransmitted data as early as possible to avoid data delay.

[0168] For another example, when the first uplink transmission is in the DTX active period and the scheduled PDCCH is in the DTX non-active period, under the existing mechanism, since C-DRX is not configured, the terminal will stop monitoring the PDCCH during the DTX OFF period and can only wait until the next most recent DTX ON to monitor the PDCCH; and in the PDCCH monitoring control method provided in the embodiment of the present application, such as Fig.11 As shown, the terminal needs to resume PDCCH monitoring after SR / NACK transmission (i.e., the first uplink transmission). It can restart a reTransmissionTimer (i.e., the second timer mentioned above) after SR / NACK transmission, and continue to monitor PDCCH before the reTransmissionTimer times out, and the length of the reTransmissionTimer is less than the DTX OFF period.

[0169] For example, Fig.12 As shown, when SR / NACK transmission (ie, the first uplink transmission) is in the DTX active period, and the scheduled PDCCH is in the DTX active period, the terminal can receive the scheduled PDCCH in the DTX ON period.

[0170] Optionally, in the embodiment of the present application, if only cell DTX is configured and PDCCH skipping is indicated, but UE C-DRX is not configured, the terminal will not enter the discontinuous reception state, that is, the terminal will continue to monitor the PDCCH.

[0171] For example, when the first uplink transmission is in the DTX non-active period, under the existing mechanism, in the DTX OFF period, the terminal will not monitor the PDCCH of the new transmission, and if it wants to schedule the new transmission, it needs to wait until the next DTX ON period, which will cause a large delay; and in the PDCCH monitoring control method provided in the embodiment of the present application, such as Fig.13 As shown, during the DTX OFF period, after SR / NACK transmission (ie, the first uplink transmission), the terminal resumes PDCCH monitoring (ie, terminates PDCCH skipping), that is, from the start of SR / NACK transmission to the end of the cell DTX non-active period where the SR / NACK transmission is located, the terminal can continuously monitor the PDCCH.

[0172] In this way, after receiving the indication of the PDCCH monitoring adaptation field, once the terminal sends an uplink NACK / SR (i.e., the first uplink transmission mentioned above), it resumes monitoring the PDCCH, even if the uplink NACK / SR falls within the cell DTXOFF time period, and continues to monitor until the start time of the most recent cell DTX / DRX ON or the end time of the cell DTX / DRXOFF.

[0173] For another example, when the first uplink transmission is in the DTX active period and the PDCCH is rescheduled in the DTX non-active period, under the existing mechanism, the terminal will not monitor the retransmitted and newly transmitted PDCCHs during the DTX OFF period and after the PDCCH skipping indication, and if the retransmitted and newly transmitted data are to be scheduled, the terminal can only wait until the next DTX ON period, which will result in a longer data delay; and in the PDCCH monitoring control method provided in the embodiment of the present application, such as Fig.14 As shown, after the SR / NACK transmission (ie, the first uplink transmission), the terminal resumes monitoring the PDCCH (ie, terminates PDCCH skipping) until the cell DTX OFF period where the SR / NACK transmission is located ends.

[0174] For another example, when the first uplink transmission is in the DTX active period and the retransmission / new transmission scheduling PDCCH is in the DTX active period, under the existing mechanism, regardless of whether the retransmission / new transmission PDCCH is in the DTX ON or DTX OFF period, due to the influence of PDCCH skipping, the terminal will not monitor the PDCCH, and can only wait until the time indicated by the PDCCH skipping indication expires or the next DTX duration to monitor the PDCCH; and in the PDCCH monitoring control method provided in the embodiment of the present application, such as Fig.15 As shown, the terminal can resume PDCCH monitoring after NACK / SR transmission (ie, the first uplink transmission), thereby avoiding data delay.

[0175] It can be seen that for the scenario with only cell DTX, under the existing mechanism, if the terminal has urgent services to schedule during the cell DTX non-activeperiod, it can only wait until the next cell DTX active period, which will cause a large delay; while in the PDCCH monitoring control method provided in the embodiment of the present application, the terminal can resume PDCCH monitoring after SR / NACK transmission, thereby effectively avoiding data transmission delays. For the scenario with both PDCCH skipping and cell DTX / DRX, under the existing mechanism, if the retransmission scheduling PDCCH corresponding to the NACK is not monitored during the cell DTXactive period, it can only wait until the next cell DTX active period to monitor, which will cause a large delay; while in the PDCCH monitoring control method provided in the embodiment of the present application, the terminal can resume PDCCH monitoring after SR / NACK transmission, thereby effectively avoiding data transmission delays.

[0176] The present application embodiment provides another PDCCH monitoring control method. Fig.16 FIG. 1 is a flow chart showing a PDCCH monitoring control method provided by an embodiment of the present application. Fig.16 As shown, the PDCCH monitoring control method provided in the embodiment of the present application may include the following step 161.

[0177] Step 161: The network side device sends first configuration information to the terminal.

[0178] The first configuration information indicates the related behavior of at least one of the cell DTX and the cell DRX of the network side device, and the first configuration information is used by the terminal to perform a first operation, which is an operation of changing the PDCCH monitoring behavior.

[0179] Optionally, in the embodiment of the present application, the first operation may include any one of the following:

[0180] Resume monitoring of a specific type of PDCCH;

[0181] Resume monitoring of all types of PDCCH;

[0182] Stop monitoring a specific type of PDCCH;

[0183] Stop monitoring all types of PDCCH;

[0184] Terminate PDCCH skipping;

[0185] Stop PDCCH search space group switching;

[0186] Stop the timer for PDCCH search space group switching;

[0187] Restart the timer for PDCCH search space group switching;

[0188] Suspend the timer for PDCCH search space group switching;

[0189] Resume the timer for PDCCH search space group switching.

[0190] Optionally, in an embodiment of the present application, after the above step 161, the PDCCH monitoring control method provided in the embodiment of the present application may further include the following step A.

[0191] Step A: The network side device receives the first uplink transmission sent by the terminal.

[0192] The first uplink transmission includes at least one of the following:

[0193] Transmission of PUSCH carrying NACK feedback;

[0194] Transmission of PUCCH carrying NACK feedback;

[0195] Transmission of SR;

[0196] Transmission of WUS;

[0197] RACH transmission;

[0198] Transmission of the first PUSCH, where the first PUSCH is used to transmit at least one of the following: a specific type of CG, a specific type of BSR, and uplink data of a specific service type.

[0199] Optionally, in the embodiment of the present application, the first PUSCH may include any of the following:

[0200] PUSCH with a specified configuration identifier;

[0201] PUSCH with specified physical layer priority;

[0202] PUSCH with a specified logical channel identity;

[0203] PUSCH with specified logical channel priority;

[0204] PUSCH carrying UCI;

[0205] PUSCH carrying CG-UCI;

[0206] PUSCH carrying BSR information.

[0207] Optionally, in the embodiment of the present application, the above-mentioned first operation may be performed by the terminal at the first moment.

[0208] The first moment mentioned above includes any of the following:

[0209] The start time of the DTX inactive period of the cell;

[0210] The start time of the DTX activation period of the cell;

[0211] an end time of a time unit of receiving a first DCI, where the first DCI is a DCI detected by the terminal and carries a PDCCH monitoring adjustment field;

[0212] The starting time of the first time unit after the terminal performs the first uplink transmission;

[0213] The starting time of the first specific time unit after the terminal performs the first uplink transmission, the first specific time unit is: the first downlink time unit, or the first downlink time unit with a PDCCH monitoring opportunity;

[0214] a start time of a target time unit, the target time unit being: a time unit separated by a first time interval from an execution end time of the first uplink transmission;

[0215] When the terminal finishes executing the first uplink transmission, the first timer started times out.

[0216] In the PDCCH monitoring control method provided in the embodiment of the present application, since the network side device can send the first configuration information indicating the related behavior of at least one of the cell DTX and cell DRX of the network side device to the terminal, so that the terminal can perform the operation of changing the PDCCH monitoring behavior, the terminal does not need to determine whether to perform PDCCH monitoring according to whether the cell is in the DTX activation period according to the existing rules, thereby improving the flexibility of the terminal in performing PDCCH monitoring.

[0217] Optionally, in an embodiment of the present application, the first moment is related to the first uplink transmission, and the first operation includes resuming monitoring of a first PDCCH, where the first PDCCH is a specific type of PDCCH or all types of PDCCHs. Exemplarily, after the above step 161, the PDCCH monitoring control method provided in the embodiment of the present application may further include the following step 162.

[0218] Step 162: The network-side device sends a downlink transmission corresponding to the first uplink transmission to the terminal.

[0219] For other specific descriptions in the embodiments of the present application and the technical effects that can be achieved by each technical feature, please refer to the relevant descriptions in the above-mentioned terminal side method embodiment. In order to avoid repetition, they will not be repeated here.

[0220] The PDCCH monitoring control method provided in the embodiment of the present application can be executed by a PDCCH monitoring control device. In the embodiment of the present application, the PDCCH monitoring control method executed by the PDCCH monitoring control device is taken as an example to illustrate the PDCCH monitoring control device provided in the embodiment of the present application.

[0221] Combination Fig.17 An embodiment of the present application provides a PDCCH monitoring control device 170 , which may include a receiving module 171 and an execution module 172 .

[0222] The receiving module 171 may be used to receive first configuration information sent by a network side device, where the first configuration information indicates a related behavior of at least one of a cell DTX and a cell DRX of the network side device. The executing module 172 may be used to execute a first operation based on the first configuration information received by the receiving module 171, where the first operation is an operation of changing a PDCCH monitoring behavior.

[0223] In one possible implementation, the first operation may include any one of the following: resuming monitoring of a specific type of PDCCH; resuming monitoring of all types of PDCCH; stopping monitoring of a specific type of PDCCH; stopping monitoring of all types of PDCCH; terminating PDCCH skipping; stopping PDCCH search space group switching; stopping the timer for PDCCH search space group switching; restarting the timer for PDCCH search space group switching; suspending the timer for PDCCH search space group switching; resuming the timer for PDCCH search space group switching.

[0224] In a possible implementation, the execution module 172 may also be used to perform a first uplink transmission before performing the first operation based on the first configuration information. The first uplink transmission includes at least one of the following: transmission of a PUSCH carrying NACK feedback; transmission of a PUCCH carrying NACK feedback; transmission of an SR; transmission of a WUS; transmission of a RACH; transmission of a first PUSCH, the first PUSCH being used to transmit at least one of the following: a specific type of CG, a specific type of BSR, or uplink data of a specific service type.

[0226] In a possible implementation, the execution module 172 can be specifically used to perform the above-mentioned first operation at a first moment based on the above-mentioned first configuration information. The first moment includes any one of the following: the start moment of entering the inactive period of the above-mentioned cell DTX; the start moment of entering the active period of the cell DTX; the end moment of the time unit of receiving the first DCI, the first DCI is the DCI carrying the PDCCH monitoring adjustment field detected by the terminal; the start moment of the first time unit after executing the above-mentioned first uplink transmission; the start moment of the first specific time unit after executing the first uplink transmission, the first specific time unit is: the first downlink time unit, or the first downlink time unit with a PDCCH monitoring opportunity; the start moment of the target time unit, the target time unit is: the time unit separated by a first time interval from the end moment of the execution of the first uplink transmission; when the first timer started at the end of the execution of the first uplink transmission times out.

[0227] In a possible implementation, the first moment is related to the first uplink transmission, and the first operation includes resuming monitoring of the first PDCCH, which is a specific type of PDCCH or all types of PDCCH. The execution module 172 can be specifically used to resume monitoring of the first PDCCH at the first moment based on the first configuration information, and stop monitoring the first PDCCH at the second moment. The second moment is: the end moment of the activation period of the first DTX of the above-mentioned cell after the first moment; or the end moment of the first inactivation period of the DTX of the cell after the first moment.

[0228] In a possible implementation, the first moment is related to the first uplink transmission, and the first operation includes resuming monitoring of the first PDCCH, which is a specific type of PDCCH or all types of PDCCH. The execution module 172 can be specifically used to start the second timer at the first moment and start resuming monitoring of the first PDCCH based on the first configuration information, and when the second timer times out, determine whether to stop monitoring the first PDCCH according to the first rule. The first rule includes: if the second timer times out during the inactive period of the above-mentioned cell DTX, the terminal stops monitoring the first PDCCH when the second timer times out; if the second timer times out during the active period of the cell DTX, the terminal keeps monitoring the first PDCCH when the second timer times out.

[0229] In a possible implementation, the first moment is related to the first uplink transmission, and the first operation includes resuming monitoring of the first PDCCH, which is a specific type of PDCCH or all types of PDCCH. The execution module 172 can be specifically used to start a third timer at the first moment and start resuming monitoring of the first PDCCH based on the first configuration information, and stop monitoring the first PDCCH according to the second rule. The time length of the third timer is less than the time length of the inactive period of the cell DTX, and the second rule includes: if the downlink transmission corresponding to the first uplink transmission is not received before the third timer times out, the terminal stops monitoring the first PDCCH when the third timer times out; if the downlink transmission corresponding to the first uplink transmission is received before the third timer times out, the terminal stops monitoring the first PDCCH at the moment of receiving the downlink transmission corresponding to the first uplink transmission.

[0230] In the PDCCH monitoring control device provided in the embodiment of the present application, since the PDCCH monitoring control device can perform the operation of changing the PDCCH monitoring behavior according to the relevant configuration of at least one of the cell DTX and the cell DRX of the network side device, it is not necessary to determine whether to perform PDCCH monitoring according to whether the cell is in the DTX activation period according to the existing rules, thereby improving the flexibility of PDCCH monitoring.

[0231] The PDCCH monitoring control device in the embodiment of the present application can be an electronic device, such as an electronic device with an operating system, or a component in an electronic device, such as an integrated circuit or a chip. The electronic device can be a terminal. Exemplarily, the terminal can include but is not limited to the types of the terminal 11 listed above, and the embodiment of the present application does not specifically limit it.

[0232] The PDCCH monitoring control device provided in the embodiment of the present application can implement each process implemented by the above-mentioned terminal side method embodiment and achieve the same technical effect. To avoid repetition, it will not be repeated here.

[0233] Combination Fig.18 , an embodiment of the present application provides another PDCCH monitoring control device 180 , and the PDCCH monitoring control device 180 may include a sending module 181 .

[0234] Among them, the sending module 181 can be used to send first configuration information to the terminal; wherein the first configuration information indicates the related behavior of at least one of the cell DTX and cell DRX of the network side device, and the first configuration information is used for the terminal to perform a first operation, and the first operation is an operation to change the PDCCH monitoring behavior.

[0235] In one possible implementation, the first operation may include any one of the following: resuming monitoring of a specific type of PDCCH; resuming monitoring of all types of PDCCH; stopping monitoring of a specific type of PDCCH; stopping monitoring of all types of PDCCH; terminating PDCCH skipping; stopping PDCCH search space group switching; stopping the timer for PDCCH search space group switching; restarting the timer for PDCCH search space group switching; suspending the timer for PDCCH search space group switching; resuming the timer for PDCCH search space group switching.
