[0031] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0032] Before describing the embodiments of the present application, a brief description of the relevant contents is given.

[0033] In the New Radio (NR) system, the network device can configure the discontinuous reception (DRX) function for the terminal device, so that the terminal device can discontinuously detect (or monitor) the PDCCH in the time domain, thereby achieving the purpose of power saving for the terminal device. When there is no data transmission, the terminal device can stop receiving the PDCCH, that is, the terminal device stops PDCCH blind detection to reduce power consumption, thereby improving the battery life of the terminal device.

[0034] In the existing Long Term Evolution (LTE) system, a DRX cycle can be configured for a terminal device in the RRC_CONNECTED state. Figure 1 As shown, the DRX cycle includes a DRX active period (Active Time) and a DRX inactive period (Inactive Time; during the DRX Active Time, the terminal device monitors and receives the PDCCH; during the DRX Inactive Time (also known as the sleep period), the terminal device does not receive the PDCCH to reduce power consumption. The transmission of paging messages is also applicable to the DRX mechanism in the RRC idle state, in which case the DRX cycle is the period of the paging message.

[0035] For the DRX mechanism, time is divided into continuous DRX cycles. The start time of each DRX cycle is the DRX ON state. During the DRX ON period, the terminal device will detect the PDCCH according to the configured monitoring (Monitoring Occasion, MO). When the terminal device detects the PDCCH, it also starts and refreshes the corresponding deactivation timer (InactivityTimer). If the DRX ON is not ended or the Inactivity Timer is not ended, the terminal device is in the DRX Active Time. The terminal device in the DRX Active Time needs to detect the PDCCH.

[0036] The NR system inherits the configuration method for DRX in the LTE system. The terminal device monitors all configured PDCCH search spaces during the DRX active time, and stops monitoring all configured PDCCH search spaces during the DRX off period. During the DRX active time, the network device can instruct the terminal device to skip or ignore PDCCH detection (PDCCH skipping) for a period of time; wherein, the PDCCH skipping indication can be carried in the DCI, such as using 2 bits of information in the DCI to indicate the number of monitoring opportunities for PDCCH skipping. A schematic diagram of a terminal device skipping PDCCH detection, as shown in Figure 2 As shown, after receiving the PDCCH skipping indication, the terminal device stops PDCCH monitoring (ie, PDCCH skipping) during the indicated monitoring period, and resumes PDCCH monitoring outside the indicated monitoring period.

[0037] The applicant has found that when the terminal device skips the PDCCH detection process, there may be a problem of PDCCH loss, such as Figure 2 As shown, if the network device sends data in a slot, the terminal device may not receive the data correctly in the slot. For the data that is not received correctly, the network device needs to perform data retransmission; and the data retransmission in the PDCCH skipping process will inevitably consume network resources, which conflicts with the PDCCH skipping implemented for energy saving. The control channel detection method provided in the embodiment of the present application can optimize the PDCCH skipping process, while saving the power consumption of the terminal device, enabling the terminal device to perform effective channel monitoring.

[0052] An optional processing flow of the control channel detection method provided in the embodiment of the present application is as follows: Figure 4 As shown, the following steps are included:

[0053] Step S201: The terminal device receives a first DCI, where the first DCI is used to determine a listening timing for skipping control channel detection.

[0054] In some embodiments, the control channel may be a PDCCH, or may be a scheduling-free PDSCH.

[0055] In some embodiments, the first DCI may be sent by a network device to a terminal device. Taking the control channel as PDCCH as an example, the X bit in the first DCI is used to directly indicate the monitoring timing of the PDCCH skipping, that is, the terminal device does not detect the PDCCH during the monitoring timing indicated by the first DCI. The first DCI may also be used to indicate the detection parameters of the control channel, and the terminal device can determine the monitoring timing of the PDCCH skipping according to the detection parameters of the control channel; wherein the detection parameters of the control channel may include at least one of the following: the detection period of the control channel, the search space set of the control channel, the format of the DCI carried by the control channel, and the type of the control channel. Here, the detection period of the control channel may be the time interval between two adjacent control channel detections; the format of the DCI carried by the control channel may be format-1 or format-0; the type of the control channel may be a control channel dedicated to the terminal device, or a control channel common to multiple terminal devices. The detection parameters of the control channel indicated by the first DCI may be different from the detection parameters received by the terminal device last time, that is, the detection parameters of the control channel have been adjusted; when the detection parameters of the control channel have been adjusted, such as changes in the detection period of the control channel or the search space set of the control channel, the terminal device will inevitably skip PDCCH detection at some monitoring opportunities when performing PDCCH detection.

[0056] Step S202: The terminal device detects the control channel in some of the monitoring opportunities in which the control channel detection is skipped.

[0057] In some embodiments, the terminal device determines part of the listening opportunities for skipping control channel detection according to the time domain parameters carried by the first DCI, and detects the control channel at the part of the listening opportunities.

[0058] In some embodiments, the first DCI may be carried in a PDCCH, and the first DCI may be used to schedule at least one of a physical downlink shared channel (PDSCH), a PDCCH, and a physical uplink shared channel (PUSCH). For different channels scheduled by the first DCI, the time domain parameter carried by the first DCI may be at least one of the following:

[0059] A first time domain offset between the first DCI and the PDSCH scheduled by the first DCI, a second time domain offset between the PDSCH scheduled by the first DCI and the Hybrid Automatic RepeatreQuest ACK (HARQ-ACK) corresponding to the PDSCH, and a third time domain offset between the first DCI and the PUSCH scheduled by the first DCI. The first time domain offset can be represented by k0, the second time domain offset can be represented by k1, and the third time domain offset can be represented by k2. A schematic diagram of the first time domain offset, such as Figure 5 As shown, the first DCI is transmitted in Slot1, the PDSCH scheduled by the first DCI is transmitted in Slot3, and the first time domain offset k0 is 2. The schematic diagram of the second time domain offset is as follows Figure 6 As shown, the first DCI is transmitted in Slot1, the first DCI is used to schedule the transmission of PDSCH in Slot3, the HARQ-ACK corresponding to the PDSCH in Slot8 of the terminal device is fed back, and the second time domain offset k1 is 5. The schematic diagram of the third time domain offset is as follows Figure 7 As shown, the first DCI is transmitted in Slot4, the first DCI is used to schedule the transmission of PUSCH in slot8, and the third time domain offset k2 is 4. The first time domain offset, the second time domain offset and the third time domain offset can be based on time slots, or can be based on frames, subframes, or symbols, etc.; the first time domain offset, the second time domain offset and the third time domain offset can be indicated by the first DCI shown.

[0060] In some embodiments, the partial monitoring opportunities may be: N monitoring opportunities starting from a first offset of a time domain position for transmitting the first DCI, where N is a positive integer.

[0061] In some optional implementations, the first offset includes: the sum of the first time domain offset, the second time domain offset and the adjustment offset. The first time domain offset is represented by k0, the second time domain offset is represented by k1, the adjustment offset is represented by m, and m is a preset integer value, then the first offset is equal to k0+k1+m. If the terminal device receives the first DCI in slot (n), the terminal device detects the control channel at N listening opportunities starting from slot (n+k0+k1+m) in the time domain position.

[0062] In some other optional implementations, the first offset includes the sum of the third time domain offset and the adjustment offset. The third time domain offset is represented by k2, the adjustment offset is represented by m, m is a preset integer value, and the first offset is equal to k2+m. If the terminal device receives the first DCI in slot (n), the terminal device detects the control channel at N listening opportunities with slot (n+k2+m) as the starting time domain position.

[0063] In some embodiments, the search space type of the control channel detected by the terminal device at the partial listening opportunity is the same as the search space type of the control channel carrying the first DCI. For example, if the search space type of the PDCCH carrying the first DCI is Type-0 search space, the search space type of the control channel detected by the terminal device at the partial listening opportunity is also Type-0 search space; if the search space type of the PDCCH carrying the first DCI is Type-1 search space, the search space type of the control channel detected by the terminal device at the partial listening opportunity is also Type-1 search space.

[0064] In some embodiments, the format of the DCI carried by the control channel detected by the terminal device in the partial listening opportunity is the same as the format of the first DCI. For example, if the format of the first DCI is format0, the format of the DCI carried by the control channel detected by the terminal device in the partial listening opportunity is also format0.

[0065] In some embodiments, the channel type scheduled by the control channel detected by the terminal device at the partial listening opportunity is the same as the channel type scheduled by the control channel carrying the first DCI. For example, if the channel type scheduled by the control channel carrying the first DCI is PUSCH, the channel type scheduled by the control channel detected by the terminal device at the partial listening opportunity is also PUSCH. If the channel type scheduled by the control channel carrying the first DCI is PDSCH, the channel type scheduled by the control channel detected by the terminal device at the partial listening opportunity is also PDSCH.

[0066] In some embodiments, if the network device needs to retransmit a data packet, the network device sends a second DCI to the terminal device, and the second DCI is used to schedule data packet retransmission. In a specific implementation, if the terminal device detects the second DCI, the terminal device can determine the time domain position of the retransmitted data packet according to the second DCI, and the terminal device will receive the retransmitted data packet at the time domain position determined according to the second DCI. In this scenario, the terminal device can stop detecting the control channel during the partial listening period. If the first DCI is used to indicate the detection parameters of the control channel, that is, the detection parameters of the control channel have changed, the terminal device can stop detecting the control channel during the partial listening period, and can also detect the control channel according to the changed detection parameters indicated by the first DCI. In a specific implementation, if the terminal device does not detect the second DCI, the terminal device detects the control channel during the partial listening period to wait for the terminal device to retransmit the data packet.

[0067] The schematic diagram of the channel detection method provided in the embodiment of the present application is as follows: Figure 8 As shown, the network device transmits all data in slot (x), but because the terminal device performs PDCCH skipping in slot (x) according to the DCI sent by the network device, the terminal device fails to successfully receive the data packet transmitted in slot (x); the network device needs to retransmit the data packet. In this scenario, the terminal device detects the control channel during part of the listening time in the PDCCH skipping listening opportunity to receive the retransmitted data packet. If the terminal device successfully receives the retransmitted data packet in the said part of the listening opportunity, the terminal device can stop detecting the control channel in the said part of the listening opportunity, and detect the control channel in slot (y) according to the DCI sent by the network device.

[0068] The control channel detection method provided in the embodiment of the present application uses part of the monitoring opportunities of the PDCCH skipping indicated by the network device as the window for data packet retransmission, which can reduce the PDCCH detection of the retransmitted data packet by the terminal device; it ensures that when the terminal device fails to successfully receive the data packet scheduled when the network device sends the PDCCH skipping indication, the retransmission of the unsuccessful received data packet can be completed quickly. In addition, since the retransmission window of the data packet is located within the monitoring opportunity of PDCCH skipping, the system delay caused by retransmitting the data packet after PDCCH skipping can be avoided. The control channel detection method provided in the embodiment of the present application expands the function of PDCCH, so that PDCCH not only has the function of scheduling PUSCH and indicating PDCCH skipping, but also has the function of indicating the time window for data packet retransmission; for data packet retransmission, no additional physical layer energy-saving signal is required, and no additional signaling is introduced, which greatly saves wireless resources. Since some of the monitoring opportunities of the terminal device in the monitoring opportunities of PDCCH skipping are related to the time domain parameters k0, k1, and k2 already carried in the PDCCH, the bits used for energy-saving indication (detecting the control channel at some of the monitoring opportunities) in the embodiment of the present application account for a small proportion of the indication information carried by the PDCCH, saving system resources. The control channel detection method provided in the embodiment of the present application can dynamically support energy saving of the terminal device according to the adjustment offset value indicated by k0, k1, k2, and the network device, and the adaptive time scale of energy saving of the terminal device can be reduced from tens of microseconds to microseconds.

[0069] Another optional processing flow of the control channel detection method provided in the embodiment of the present application is as follows: Fig. 9 As shown, the following steps are included:

[0070] Step S301: The network device sends a first DCI to the terminal device, where the first DCI is used by the terminal device to determine a listening opportunity for skipping control channel detection, and part of the listening opportunities for skipping control channel detection are used by the terminal device to detect control channels.

[0071] In some embodiments, the control channel may be a PDCCH, or may be a scheduling-free PDSCH.

[0072] In some embodiments, taking the control channel as PDCCH as an example, the X bit in the first DCI is used to directly indicate the monitoring timing of the PDCCH skipping, that is, the terminal device does not detect the PDCCH during the monitoring timing indicated by the first DCI. The first DCI can also be used to indicate the detection parameters of the control channel, and the terminal device can determine the monitoring timing of the PDCCH skipping according to the detection parameters of the control channel; wherein the detection parameters of the control channel may include at least one of the following: the detection period of the control channel, the search space set of the control channel, the format of the DCI carried by the control channel, and the type of the control channel. Here, the detection period of the control channel may be the time interval between two adjacent control channel detections; the format of the DCI carried by the control channel may be format-1 or format-0; the type of the control channel may be a control channel dedicated to the terminal device, or a control channel common to multiple terminal devices. The detection parameters of the control channel indicated by the first DCI may be different from the detection parameters received by the terminal device last time, that is, the detection parameters of the control channel have been adjusted; when the detection parameters of the control channel have been adjusted, such as changes in the detection period of the control channel or the search space set of the control channel, the terminal device will inevitably skip PDCCH detection at some monitoring opportunities when performing PDCCH detection.

[0073] In some embodiments, the partial monitoring opportunities may be: N monitoring opportunities starting from a first offset of a time domain position for transmitting the first DCI, where N is a positive integer.

[0074] In some optional implementations, the first offset includes: the sum of the first time domain offset, the second time domain offset and the adjustment offset. The first time domain offset is represented by k0, the second time domain offset is represented by k1, the adjustment offset is represented by m, and m is a preset integer value, then the first offset is equal to k0+k1+m. If the terminal device receives the first DCI in slot (n), the terminal device detects the control channel at N listening opportunities starting from slot (n+k0+k1+m) in the time domain position.

[0075] In some other optional implementations, the first offset includes the sum of the third time domain offset and the adjustment offset. The third time domain offset is represented by k2, the adjustment offset is represented by m, m is a preset integer value, and the first offset is equal to k2+m. If the terminal device receives the first DCI in slot (n), the terminal device detects the control channel at N listening opportunities with slot (n+k2+m) as the starting time domain position.

[0076] In some embodiments, the search space type of the control channel detected by the terminal device at the partial listening opportunity is the same as the search space type of the control channel carrying the first DCI.
