In the embodiment of the present application, the "protocol" may refer to a standard protocol in the communication field, for example, may include the LTE protocol, the NR protocol, and related protocols applied to future communication systems, which is not limited in the present application.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific examples. The following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them belong to the protection scope of the embodiments of the present application. The embodiment of the present application includes at least part of the following contents.

For the consideration of terminal power saving, the NR system supports the Discontinuous Reception (DRX) transmission mechanism. The main principle is to realize discontinuous reception of signals in the time domain through semi-static configuration. When there is no data transmission, the power consumption can be reduced by stopping receiving the PDCCH (at this time, the PDCCH blind detection will be stopped), thereby increasing the battery life of the terminal.

For example, in an LTE system, the DRX configuration method is to configure a DRX cycle (DRX cycle) for a UE in a Radio Resource Control (RRC) connected (RRC_CONNECTED) state. As shown in Figure 2, the DRX cycle consists of "Active Time" and "Inactive Time". During the "Active Time", the UE monitors and receives the PDCCH (Activation Period); during the "Inactive Time" "During the time, the UE does not receive PDCCH to reduce power consumption (sleeping period). In addition, the transmission of the paging message is also a DRX mechanism in the RRC idle state, and the DRX cycle at this time is the cycle of the paging message.

How "Active Time" and "Inactive Time" are formed: Time is divided into successive DRX Cycles. Each DRX cycle starts to enter the DRX start (DRX ON) state. When DRX is ON, the UE will detect the PDCCH according to the configured monitoring occasion (Monitoring Occasion, MO). When the UE detects the PDCCH, it also starts and refreshes an Inactivity Timer. If the DRX ON is not over or the Inactivity Timer is not over, the UE is in Active Time. The UE in Active Time needs to detect PDCCH.

5G NR also follows the energy-saving mechanism of LTE, and the DRX configuration method defined by it inherits the DRX configuration of LTE. The enhanced mechanism for energy saving is introduced in 5G evolution, including: PDCCH skipping and PDCCH search space switching.

PDCCH skipping is similar to the DRX mechanism, and the PDCCH skipping mechanism is to ensure that the number of PDCCH detections is reduced.

The specific method is to let the terminal equipment receive a format indicated by the control channel. Taking downlink scheduling as an example, a certain number of bits are provided in the indication format of the control channel PDCCH to indicate the unit of subsequent PDCCH skipping. For example, 2 bits in the control channel indication format are used for indication. Figure 3 demonstrates how PDCCH shipping works.

PDCCH search space switching: mainly switching between different PDCCHs (Search Space Set Group, SSSG). The corresponding SSSG may represent a state when the SSSG is switched. As shown in Fig. 4, at most 3 SSSGs are supported adaptively in PDCCH detection. The indication field in each received downlink control information (Downlink Control Information, DCI) can indicate the corresponding state that needs to be switched. For the default SSSG, no timer needs to be started. When switching to other SSSG, the timer starts at the same time. After the timer expires, switch to the default SSSG.

In some embodiments, PDCCH skipping and search space switching can be simultaneously indicated by the same DCI.

While introducing PDCCH skipping and search space switching technologies, PDCCH DCI also needs to indicate other dynamic downlink reception adjustments. For example, the scheduling DCI simultaneously indicates how to determine the PDCCH Skipping time and the switched search space when the Band Width Part (BWP) is switched.

When the PDCCH indicated by the handover is lost, how can it be ensured that the base station and the terminal understand the PDCCH adjustment and the BWP adjustment correctly and consistently. However, if the data scheduled by the PDCCH cannot be received correctly, a new PDCCH is required to schedule data retransmission as soon as possible. This brings about the problem of how to receive PDCCH retransmission as soon as possible on the new BWP.

Based on the above technical problems, this application proposes a scheduling indication scheme. The network device uses x first-type bits in the first DCI to indicate the PDCCH detection information after adjusting the first PDCCH, and through the first DCI. The y second type bits are used to indicate switching from the first BWP to the second BWP. That is, the network device can simultaneously instruct to adjust PDCCH detection information and BWP switching through one DCI, which can reduce signaling overhead.

The technical scheme of the present application is described in detail below through specific examples.

FIG. 5 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG. 5 , the wireless communication method 200 may include at least part of the following content:

S210, the network device sends the first DCI to the terminal device; where the first DCI is carried by the first PDCCH, and the x first type bits in the first DCI are used to indicate the PDCCH detection information after the first PDCCH is adjusted, The y second-type bits in the first DCI are used to indicate switching from the first BWP to the second BWP, and both x and y are positive integers;

S220. The terminal device receives the first DCI.

In this embodiment of the present application, the network device can simultaneously instruct to adjust PDCCH detection information and BWP switching through the first DCI, which can reduce signaling overhead.

In some embodiments, the adjusted PDCCH detection information indicated by the x first-type bits corresponds to ignoring at least one PDCCH detection at a time. In other words, the x first-type bits may indicate to ignore at least one PDCCH detection once, or, the x first-type bits may indicate to adjust the PDCCH detection parameter 1, and the adjusted PDCCH detection parameter 1 corresponds to one-time ignore at least A PDCCH detection. Optionally, the at least one PDCCH detection may be the PDCCH detection before the next DCI indicating to adjust the PDCCH detection is received, or the at least one PDCCH detection may be the PDCCH detection before the next PDCCH detection period.

In some embodiments, the adjusted PDCCH detection information indicated by the x first-type bits corresponds to one-time neglect of PDCCH detection within the first duration. In other words, the x first-type bits may indicate to ignore the PDCCH detection within the first duration once, or the x first-type bits may indicate to adjust the PDCCH detection parameter 2, and the adjusted PDCCH detection parameter 2 corresponds to once The PDCCH detection within the first duration is simply ignored. That is, the adjusted PDCCH detection information indicated by the x first-type bits corresponds to ignoring all PDCCH detections within the first duration at one time.

In some embodiments, the adjusted PDCCH detection information indicated by the x first-type bits corresponds to one-time neglect of at least one PDCCH detection within the first duration. In other words, the x first-type bits may indicate to ignore at least one PDCCH detection within the first duration at one time, or the x first-type bits may indicate to adjust the PDCCH detection parameter 3, and the adjusted PDCCH detection parameter 3 Correspondingly ignoring at least one PDCCH detection within the first time period at one time. Optionally, the at least one PDCCH detection may be part or all of the PDCCH detection within the first duration.

In some embodiments, the adjusted PDCCH detection information indicated by the x first type bits corresponds to ignoring the PDCCH detection in the first PDCCH detection period once. In other words, the x first-type bits may indicate to ignore the PDCCH detection in the first PDCCH detection period at one time, or the x first-type bits may indicate to adjust the PDCCH detection parameter 4, and the adjusted PDCCH detection parameter 4 Correspondingly ignore the PDCCH detection in the first PDCCH detection period once. That is, the adjusted PDCCH detection information indicated by the x first-type bits corresponds to ignoring all PDCCH detections in the first PDCCH detection period at one time.

In some embodiments, the adjusted PDCCH detection information indicated by the x first-type bits corresponds to ignoring at least one PDCCH detection in the first PDCCH detection period at one time. In other words, the x first-type bits may indicate to ignore at least one PDCCH detection in the first PDCCH detection period at one time, or the x first-type bits may indicate to adjust the PDCCH detection parameter 5, and the adjusted PDCCH detection Parameter 5 corresponds to ignoring at least one PDCCH detection in the first PDCCH detection period once. Optionally, the at least one PDCCH detection may be a part or all of the PDCCH detections in the first PDCCH detection period.

In some embodiments, the first duration is pre-configured or agreed by the protocol, or the first duration is configured by the network device through the first DCI, or the first duration is configured by the network device through the first PDCCH Alternatively, the first duration is determined based on parameters carried in the first DCI, or the first duration is determined based on parameters carried in the first PDCCH.

Specifically, for example, the first duration may be a period of time in one PDCCH detection cycle, or the first duration may be a period of time in multiple PDCCH detection cycles, or the first duration may be a period of time in a PDCCH detection cycle Multiple periods of time, or, the first duration may be multiple periods of time within multiple PDCCH detection cycles. This application is not limited to this.

In some embodiments, the first PDCCH detection cycle is pre-configured or agreed by the protocol, or the first PDCCH detection cycle is configured by the network device through the first DCI, or the first PDCCH detection cycle is configured by the network device Configured through the first PDCCH, or, the first PDCCH detection cycle is determined based on parameters carried in the first DCI, or, the first PDCCH detection cycle is determined based on parameters carried in the first PDCCH.

In some embodiments, the first duration is calculated by the following formula 1:

T=N_slot1/u1 Formula 1

Wherein, T represents the first duration, and the unit of the first duration is millisecond (ms), N_slot1 represents the number of time slots on the first BWP, and u1 represents the subcarrier spacing (Subcarrier spacing, SCS) on the first BWP coefficient.

That is, in Formula 1, the first duration may be an absolute time.

In some embodiments, the first duration is determined based on N_slot2, where the N_slot2 represents the number of time slots on the second BWP for which PDCCH detection is ignored. Specifically, for example, the first duration is a duration corresponding to a time slot for ignoring PDCCH detection on the second BWP.

In some embodiments, the N_slot2 is calculated by the following formula 2:

N_slot2＝N_slot1*u2/u1 Formula 2

Wherein, N_slot1 indicates the number of time slots on the first BWP, u1 indicates the SCS coefficient on the first BWP, and u2 indicates the SCS coefficient on the second BWP.

For example, if the SCS on the first BWP is 15kHz, then u1=0; if the SCS on the first BWP is 30kHz, then u1=1; if the SCS on the first BWP is 60kHz, then u1=2; SCS is 120kHz, then u1=3.

For example, if the SCS on the second BWP is 15kHz, then u2=0; if the SCS on the second BWP is 30kHz, then u2=1; if the SCS on the second BWP is 60kHz, then u2=2; SCS is 120kHz, then u2=3.

In some embodiments, the first duration is calculated by the following formula 3:

T＝N_slot1/u1+Z Formula 3

Among them, T represents the first duration, and the unit of the first duration is milliseconds (ms), N_slot1 represents the number of time slots on the first BWP, u1 represents the SCS coefficient on the first BWP, and Z represents the time domain offset .

In some embodiments, the first duration is determined based on the following formula 4:

T＝N_slot2+Z Formula 4

Wherein, T represents the first duration, N_slot2 represents the number of time slots for which PDCCH detection is ignored on the second BWP, and Z represents a time domain offset. Specifically, for example, the N_slot2 is calculated by the above formula 2.

In some embodiments, the value of Z is configured by the network device through the first DCI, or the value of Z is configured by the network device through the first PDCCH, or the value of Z is based on the first PDCCH The time domain resource occupied by an acknowledgment (Acknowledgment, ACK) is determined; wherein, the first ACK is the feedback information of the terminal device for the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) scheduled by the first PDCCH.

In some embodiments, the adjusted PDCCH detection information indicated by the x first type bits corresponds to switching from the first SSSG to the second SSSG. Optionally, the second SSSG is determined based on the SSSG configuration corresponding to the second BWP. Optionally, when the second BWP has no corresponding SSSG configuration, the second SSSG is the default SSSG corresponding to the second BWP, or the second SSSG is the preferentially used SSSG corresponding to the second BWP .

In some embodiments, the adjusted PDCCH detection information indicated by the x first type bits corresponds to switching from the first SSSG to the second SSSG; wherein the second SSSG is determined based on the SSSG configuration corresponding to the second BWP .

Specifically, for example, the number of PDCCH detections corresponding to the first SSSG is greater than the number of PDCCH detections corresponding to the second SSSG, that is, the adjusted PDCCH detection information corresponds to ignoring a certain number of PDCCH detections.

For another specific example, the number of PDCCH detections corresponding to the first SSSG is smaller than the number of PDCCH detections corresponding to the second SSSG, that is, the adjusted PDCCH detection information corresponds to a certain number of PDCCH detections.

In some embodiments, the adjusted PDCCH detection information indicated by the x first-type bits may simultaneously correspond to: ignoring a certain number of PDCCH detections and switching from the first SSSG to the second SSSG, which is not limited in the present application.

In this embodiment of the present application, the network device can reliably use the first DCI to perform SSSG handover and BWP handover, that is, it can reliably use the scheduling DCI to perform multiple handovers.

In the embodiment of this application, the content indicated by the x first-type bits may conflict with the content indicated by the y second-type bits. In this case, the terminal device can ignore the x first-type bits or, the terminal device can ignore the y second-type bits, or the terminal device can preferentially adjust the PDCCH detection information based on the x first-type bits, and then adjust the PDCCH detection information based on the y The second type of bits performs downlink BWP switching.

In some embodiments, the terminal device switches the downlink BWP from the first BWP to the second BWP according to the y second-type bits; and the terminal device ignores the x first-type bits. That is, in response to the first DCI, the terminal device only performs downlink BWP switching, and the terminal device does not adjust PDCCH detection information. Specifically, for example, the terminal device may determine to only perform downlink BWP switching based on its own implementation, and not to adjust PDCCH detection information. As another specific example, the terminal device may determine to only perform downlink BWP switching and not adjust PDCCH detection information based on the instruction of the network device.

In some embodiments, when the terminal device ignores the x first-type bits, the terminal device switches the SSSG to the default SSSG corresponding to the second BWP, or the terminal device switches the SSSG to the second BWP The preferred SSSG corresponding to the two BWPs.

In some embodiments, the terminal device adjusts PDCCH detection information after the first PDCCH according to the x first-type bits; and the terminal device ignores the y second-type bits. That is, in response to the first DCI, the terminal device only adjusts PDCCH detection information, and the terminal device does not perform downlink BWP switching. Specifically, for example, the terminal device may determine only to adjust PDCCH detection information based on its own implementation, and not perform downlink BWP switching. As another specific example, the terminal device may determine based on the indication of the network device to only adjust the PDCCH detection information, and not perform downlink BWP switching.

In some embodiments, the terminal device adjusts the PDCCH detection information after the first PDCCH according to the x first type bits; and after adjusting the PDCCH detection information after the first PDCCH, the terminal device adjusts the PDCCH detection information according to the y second-type bits to switch the downlink BWP from the first BWP to the second BWP. That is, in response to the first DCI, the terminal device first adjusts PDCCH detection information, and then performs downlink BWP switching.

In some embodiments, the terminal device adjusts the PDCCH detection information after the first PDCCH within a first duration according to the x first-type bits; and the terminal device adjusts the PDCCH detection information after the first duration according to the y second-type bits Bits switch the downlink BWP from the first BWP to the second BWP; wherein, the downlink BWP of the terminal device remains unchanged within the first duration; PDCCH detection information after adjustment indicated by the x first type bits In the case of ignoring at least one PDCCH detection at one time, the first duration is the duration corresponding to the at least one PDCCH detection; or, the PDCCH detection information after the adjustment indicated by the x first type bits corresponds to switching from the first SSSG In the case of switching to the second SSSG, the first duration is the duration of switching from the first SSSG to the second SSSG.

Specifically, for example, as shown in FIG. 6, the terminal device detects the PDCCH at a monitoring opportunity indicating no skipping (Skipping), and detects the first PDCCH, wherein the first PDCCH schedules data transmission on the PDSCH, and the first PDCCH includes The first DCI, x bits of the first type in the first DCI indicate to ignore a certain number of PDCCH detections, and y bits of the second type in the first DCI indicate to switch from the first BWP to the second BWP. As shown in FIG. 6 , after the terminal equipment feeds back the correct reception (ACK) of the downlink data (PDSCH), the terminal equipment switches the downlink BWP from the first BWP to the second BWP according to the y second type bits. That is, before the downlink data (initial transmission or retransmission) of the terminal device is successfully received, the terminal device keeps the downlink BWP unchanged.

In the embodiment of the present application, the first PDCCH can simultaneously support the PDSCH scheduling function, the BWP switching function, and the PDCCH detection and adjustment function (that is, the energy saving indication function), without requiring additional energy saving physical layer signals. Thus, wireless resources are greatly saved. In the embodiment of the present application, there is no additional energy saving indication information bit in the first PDCCH.

The embodiment of the present application can reliably use PDCCH skipping (skipping) to implement a function of energy saving at the terminal side that is better than DRX. By introducing a small retransmission window (as shown in Figure 6), the terminal device can reduce the PDCCH detection for retransmission data. This solution can ensure that when the terminal device sends out the PDCCH skipping instruction, the data of the scheduled packet is lost, and the retransmission of the remaining data can be completed quickly. At the same time, it avoids the delay caused by data retransmission after the end of PDCCH skipping.

The embodiment of the present application may not rely on other signaling to instruct the terminal to save power for retransmission detection. Of course, if other energy saving signaling is used, more signaling loss will be introduced.

The embodiment of the present application can more dynamically support terminal equipment energy saving and BWP switching than the DRX mechanism. More flexible, energy-saving self-adaptation does not affect BWP configuration changes.

In this application, the resource corresponding to the access channel is not limited to a single carrier, and the involved control channel receiving method can be extended to the configuration of multiple carriers.

In the embodiments of the present application, the adjusted PDCCH detection information indicated by the x first-type bits is mainly the receiving of skipping PDCCH/adjusted PDCCH detection, and is also applicable to behaviors of other terminal devices. For example, the terminal device may disable other signal reception according to the signaling, such as disabling channel measurement of the terminal device or data reception of the terminal device and overlapping retransmission timing definition. The behavior of the terminal device can be extended to transmit behavior, that is, to trigger the Discontinuous Transmission (DTX) of the terminal device.

Therefore, in this embodiment of the application, the network device uses x first-type bits in the first DCI to indicate the PDCCH detection information after adjusting the first PDCCH, and uses y second-type bits in the first DCI to use Instructs to switch from the first BWP to the second BWP. That is, the network device can simultaneously instruct to adjust PDCCH detection information and BWP switching through one DCI, which can reduce signaling overhead.
