Title: Dormancy indication method and apparatus, terminal, and network-side device

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of International Application No. PCT/CN2021/107260, filed Jul. 20, 2021, which claims priority to Chinese Patent Application No. 202010718638.4, filed Jul. 23, 2020. The entire contents of each of the above-referenced applications are expressly incorporated herein by reference. 
    
    
     TECHNICAL FIELD 
     This application relates to the field of wireless communications technologies, and in particular, to a dormancy indication method and apparatus, a terminal, and a network-side device. 
     BACKGROUND 
     A 5 th  Generation (5G) New Radio (NR) system supports Carrier Aggregation (CA), and may configure and activate multiple Component Carrier (CC) or cells for User Equipment (UE), and supports cross-carrier scheduling during the CA. In addition, NR also supports a scenario of Multiple Transmission and Reception Panel (M-TRP), and scheduling, transmission, and receiving of data may also be performed by the M-TRPs on the UE. In the current NR system, one cell can only be scheduled by one scheduling cell (that is, can only schedule itself or be scheduled by another cell), and a Primary Cell (Pcell) can only be scheduled by the primary cell. 
     In the prior art, to save power consumption, a Discontinuous Reception (DRX) mechanism is configured for a terminal. To further achieve power saving under DRX configuration, a downlink control information format 2-6 with a Cyclic Redundancy Check (CRC) scrambled by a Power Saving Radio Network Temporary Indicator (PS-RNTI) (DCI format 2-6 with CRC scrambled by PS-RNTI, DCP) may be configured before a DRX period. A wake-up indication field in the DCP is used for indicating whether the UE enables an on duration timer of next DRX period, or the DCP indicates whether a Media Access Control (MAC) layer enables an on duration timer of next DRX period. In a case that the timer is enabled, the UE needs to monitor a PDCCH within the timer; otherwise, the UE does not monitor the PDCCH. The DCP can only be configured on the Pcell, and the Power Saving RNTI (PS-RNTI) is a power-consumption-saving RNTI. The DCI format 2-6 exists outside of an activation time. Currently, the DCP can be configured only when Connected DRX (DRX) is configured. 
     Currently, for two information fields of the DCI format 2-6: 
     (1) a wake-up indication field, such as 1 bit, is used for indicating whether the UE enables the on duration timer of the next DRX period; and 
     (2) a Secondary Cell (Scell) dormancy indication information field (such as 0, 1, 2, 3, 4, or 5 bits) is used for indicating whether an Scell of the UE enters a dormancy behavior during the CA. 
     In addition, the Scell dormancy indication field in the DCI format 2-6 may be further used for indicating whether an Scell group is switched to a dormant Bandwidth Part (BWP) in a unit of Scell group. Each bit in the field correspondingly indicates one Scell group. 
     To enhance coverage of a control channel, the Pcell is generally deployed on low-frequency-band carriers. On the other hand, bandwidths of the low-frequency-band carriers are insufficient, and most of low-frequency-band carriers have been deployed to other systems (for example, an LTE system). Therefore, a high-frequency-band carrier may be configured as the Scell and the Pcell may be scheduled through the Scell to resolve a problem of limited capacity of the control channel of the Pcell, to reduce overheads of the Physical Downlink Control Channel (PDCCH) on the Pcell. 
     However, in the prior art, only Downlink Control Indicator (DCI) of the Pcell is supported to perform a dormancy indication. If the Pcell cannot perform the dormancy indication for a specific reason, the objective of power saving cannot be achieved.

     A dormancy indication method provided in the embodiments of this application is described below through specific embodiments and application scenarios thereof with reference to the accompanying drawings. 
       FIG.  2    is a flowchart of a dormancy indication method according to an embodiment of this application. A method  200  may be performed by a terminal. In other words, the method may be performed by software or hardware installed on the terminal. As shown in  FIG.  2   , the method may include the following steps. 
     S 210 . Receive target control information on a target cell, where the target control information carries dormancy indication information, and the target cell includes a first cell and/or a second cell. 
     In this embodiment of this application, the second cell can be scheduled by the first cell, or the second cell can schedule itself and the second cell can be scheduled by the first cell. For example, the second cell may be a Pcell, the first cell may be an Scell, the Scell may schedule the Pcell, and the Pcell can schedule itself. This is not limited herein. In some cases, the Pcell may not schedule itself. For example, in a case that the Pcell is instructed to be dormant, the Pcell may not schedule itself. 
     In this embodiment of this application, the target control information carrying the dormancy indication information may be transmitted on the first cell, or may be transmitted on the second cell, or may be transmitted on the first cell and the second cell. 
     The target control information includes, but is not limited to: at least one of downlink control information (DCI), a MAC control element (Control Element, CE), a PDCCH, RRC signaling, or the like. 
     In a case that the target control information is DCI, the DCI may be predetermined DCI, for example, DCI with a predetermined format, or DCI with a predetermined type. 
     S 212 . Determine a scheduling state of the first cell based on the dormancy indication information. 
     In this embodiment of this application, the dormancy indication information may indicate whether one or more cells (for example, one or more Scells) of the terminal during CA are dormant. 
     In this embodiment of this application, a scheduling state of one cell refers to whether the cell is activated or dormant, whether the cell may schedule itself, whether the cell may schedule another cell (including a primary cell or a secondary cell), whether the cell may be scheduled by another cell, and the like. 
     After receiving the dormancy indication information, the terminal may determine the scheduling state of the first cell, for example, whether the first cell is in a non-dormant state. 
     That the first cell is in a non-dormant state means that the first cell is in an activated state, or the first cell is in corresponding scheduling, or receiving of a PDCCH of the first cell is maintained, or the like. 
     That the first cell is in a dormant state means that the first cell is in a deactivated state, or the first cell has no corresponding scheduling, or monitoring and/or receiving of the PDCCH of the first cell are not performed, or the like. 
     In this embodiment of this application, target control information is transmitted on a first cell and/or a second cell of a terminal, and the target control information carries dormancy indication information, where the second cell can be scheduled by the first cell, or the second cell can schedule itself and the second cell can be scheduled by the first cell; and the terminal determines a scheduling state of the first cell based on the dormancy indication information. In this way, when a primary cell cannot perform a dormancy indication for a specific reason, for example, the primary cell is used as being scheduled, another cell sends a dormancy indication to the primary cell, to achieve the objective of power saving. 
     In an implementation, in S 212 , the determining a scheduling state of the first cell based on the dormancy indication information includes: determining, based on the dormancy indication information, that the first cell is in the non-dormant state. 
     In the above implementation, the first cell is in the non-dormant state, so that a situation in which the first cell cannot schedule the second cell due to entering dormancy can be avoided. 
     In an implementation, to enable the first cell to be in the non-dormant state, the first cell may not belong to any cell group. In this way, it can be ensured that the target control information does not include dormancy indication information indicating whether the first cell is dormant, that is, the target control information does not include the dormancy indication information corresponding to the first cell, so as to ensure that the first cell is in the non-dormant state. In some embodiments, the first cell is not configured with a dormant BWP. In this way, it can also be ensured that the first cell is in the non-dormant state. 
     In the above implementation, a network side may ensure that the first cell does not belong to any cell group, for example, the network side may not configure the first cell to any cell group when configuring cell groups. In some embodiments, the network side may not configure the dormant BWP for the first cell. 
     For example, assuming that the first cell is an Scell #1, the network side ensures that the Scell #1 does not belong to any Scell group (that is, does not correspond to a dormancy indication), or the network side does not configure a dormant BWP for the Scell #1. 
     In exemplary applications, the network side and the terminal may pre-determine that the first cell does not belong to any cell group, or the network side may indicate that the first cell of the terminal does not belong to any cell group. This is not specifically limited in this embodiment. 
     In another implementation, the first cell may also belong to a first cell group and/or the first cell may also be configured with a dormant BWP. In this case, indication information included in the dormancy indication information corresponds to the target cell and/or a target cell group, where the target cell is a cell other than the first cell, and the target cell group is a cell group other than the first cell group. That is, in the implementation, the dormancy indication information does not include indication information corresponding to the first cell or the first cell group, that is, the dormancy indication information does not indicate whether the first cell and/or the first cell group are dormant. Through the implementation, it can also be ensured that the terminal may determine that the first cell is in the non-dormant state when determining a dormant state of the first cell based on the dormancy indication information. 
     For example, assuming that the first cell is an Scell #1, the target control information may include one or more bits, and there is a mapping relationship between each bit and one Scell or one Scell group. In the implementation, there is a correspondence, for example, a one-by-one correspondence, between each bit and an Scell other than the Scell #1 or between each bit and an Scell group other than an Scell group to which the Scell #1 belongs. 
     In another example, by using an example in which an Scell scheduling a Pcell is an Scell #1, UE has 5 Scell groups, and an Scell group to which the Scell #1 belongs is an Scell group #0. Therefore, a dormancy indication includes 4 bits corresponding to an Scell group #1/2/3/4 respectively. In some embodiments, the UE has 5 Scells, namely, Scell #0/1/2/3/4, and an Scell group to which the Scell #1 belongs is an Scell group #1. Therefore, the dormancy indication includes 4 bits corresponding to an Scell #0/2/3/4 respectively. 
     In another implementation, the first cell belongs to a first cell group, and the dormancy indication information includes target information corresponding to the first cell or the first cell group, where the target information indicates the non-dormant state. That is, the target information corresponding to the first cell or the first cell group in the dormancy indication information always indicates the non-dormant state. By using the implementation, in S 212 , the terminal may determine, according to the dormancy indication information, that the first cell is in the non-dormant state. 
     For example, assuming that the first cell is an Scell #1, the target control information may include one or more bits, and there is a mapping relationship between each bit and one Scell or one Scell group, in the implementation, a value of a bit corresponding to the Scell #1 is 1 (that is, a value corresponding to the non-dormant state), or a value of a bit corresponding to an Scell group to which the Scell #1 belongs is 1 (that is, a value corresponding to being non-dormant). 
     In another example, by using an example in which an Scell scheduling a Pcell is an Scell #1, UE has 5 Scell groups, a dormancy indication includes 5 bits, and an Scell group to which the Scell #1 belongs is an Scell group #0. Assuming that a bit # 0  of the dormancy indication corresponds to the Scell group #0, a value of the bit is fixed to 1 (that is, a value corresponding to being non-dormant). In some embodiments, the UE has 5 Scells, namely, Scell #0/1/2/3/4, and the dormancy indication includes 5 bits. Assuming that a bit # 1  of the dormancy indication corresponds to the Scell #1, a value of the bit is fixed to 1. 
     In another implementation, in a case that the dormancy indication information includes target information corresponding to the first cell or the first cell group, at least one of the following processing (1) or (2) may be performed when the scheduling state of the first cell is determined based on the dormancy indication information. 
     (1) Determine to ignore the target information. 
     In the implementation, the terminal may directly ignore the target information corresponding to the first cell or the first cell group in the dormancy indication information, that is, the terminal always determines that the first cell is in the non-dormant state regardless of whether the target information indicates dormancy. 
     In some embodiments, the target information is determined to be ignored in a case that the target information indicates dormancy, and the dormant state of the first cell may be determined according to the indication of the target information in a case that the target information indicates non-dormancy. 
     That the target information indicates dormancy may mean that the target information corresponding to the first cell in the dormancy indication information indicates dormancy, or may mean that the target information corresponding to the first cell group in the dormancy indication information indicates the dormant state. 
     For example, assuming that the first cell is an Scell #1, the target control information may include one or more bits, and there is a mapping relationship between each bit and one Scell or one Scell group, in the implementation, in a case that a value of a bit corresponding to the Scell #1 or an Scell group to which the Scell #1 belongs indicates dormancy (for example, the bit=0), the indication of the bit is ignored. 
     In another example, by using an example in which an Scell scheduling a Pcell is an Scell #1, UE has 5 Scell groups, a dormancy indication includes 5 bits, and an Scell group to which the Scell #1 belongs is an Scell group #0. Assuming that a bit # 0  of the dormancy indication corresponds to the Scell group #0, the UE ignores the bit when determining a meaning of the dormancy indication. In some embodiments, the UE has 5 Scells, namely, Scell #0/1/2/3/4, and the dormancy indication includes 5 bits. Assuming that a bit # 1  of the dormancy indication corresponds to the Scell #1, the UE ignores the bit when determining a meaning of the dormancy indication. 
     (2) Determine that the target information is valid for cells other than the first cell. 
     In the implementation, the target information is not applied to or is invalid for the first cell. For example, it may be directly determined that the target information is not applied to or is invalid for the first cell, that is, regardless of whether the target information indicates dormancy, the terminal does not apply the target information to the first cell or the first cell group, and determines that the first cell is in the non-dormant state. 
     In some embodiments, it may be determined that the target information is invalid for the first cell or the first cell group in a case that the target information indicates dormancy. Further, it may be determined that the target information is valid for the cells other than the first cell. The target information may also be valid for the first cell in a case that the target information indicates non-dormancy. 
     For example, assuming that the first cell is an Scell #1, the target control information may include one or more bits, and there is a mapping relationship between each bit and one Scell or one Scell group, in the implementation, in a case that a value of a bit corresponding to the Scell #1 or an Scell group to which the Scell #1 belongs indicates dormancy (for example, the bit=0), the bit is not applied to or is invalid for the Scell #1, but is applied to or is valid for other Scells. For example, the bit may be valid for other Scells located in the same Scell group as the Scell #1. 
     In another example, by using an example in which an Scell scheduling a Pcell is an Scell #1, UE has 5 Scell groups, a dormancy indication includes 5 bits, and an Scell group to which the Scell #1 belongs is an Scell group #0. Assuming that a bit # 0  of the dormancy indication corresponds to the Scell group #0, if the bit=0, active DL BWPs of other Scells other than the Scell #1 in the Scell group are switched to dormant BWPs, that is, the UE does not monitor PDCCHs on the other Scells other than the Scell #1 in the Scell group. 
     In an implementation, in S 212 , the determining a dormant state of the first cell based on the dormancy indication information may also include: determining, in a case that the dormancy indication information indicates that the first cell is dormant, that the first cell enters the dormant state, and the first cell cannot schedule any cell. In the implementation, in a case that the dormancy indication information indicates that the first cell is dormant, the first cell enters the dormant state. Therefore, the PDCCH of the first cell is no longer used to indicate power control, for example, indicate a Slot Format Indication (SFI) and/or schedule data and/or signals of the first cell or other cells, or in other words, the terminal no longer monitors the PDCCH of the first cell. 
     That the dormancy indication information indicates that the first cell is dormant may mean that the dormancy indication information directly indicates that the first cell is dormant, or may mean that the dormancy indication information indicates that the first cell group to which the first cell belongs is dormant. 
     For example, assuming that the first cell is an Scell #1, the target control information may include one or more bits, and there is a mapping relationship between each bit and one Scell or one Scell group, in the implementation, when a bit corresponding to the Scell #1 or a bit corresponding to an Scell group to which the Scell #1 belongs indicates dormant, the Scell #1 instructed to be dormant cannot perform any scheduling, that is, the terminal no longer monitors the PDCCH of the Scell #1. 
     In another implementation, in S 212 , the determining a dormant state of the first cell based on the dormancy indication information may also include: determining, in a case that the dormancy indication information indicates that the first cell is dormant, that the first cell enters the dormant state, and the first cell cannot schedule the second cell. That is, in the implementation, when the dormancy indication information indicates that the first cell is dormant, it is determined that the first cell only cannot schedule the second cell, but may schedule itself or schedule another cell according to configuration. In the implementation, that the first cell cannot schedule the second cell means that there is, on the first cell, no PDCCH scheduling data and/or a signal of the second cell, and/or no PDCCH performing power control on the second cell and/or indicating an SFI. However, there may be PDCCHs that may schedule other cells, that is, there may be, on the first cell, PDCCHs scheduling data and/or signals of cells other than the second cell. Therefore, the terminal still needs to monitor the PDCCH of the first cell. 
     For example, assuming that the first cell is an Scell #1 and the second cell is a Pcell, in the implementation, when the Scell #1 or an Scell group to which the Scell #1 belongs is instructed to be dormant, the Scell #1 can no longer schedule the Pcell, which is equivalent to deactivating a function of scheduling the Pcell by the Scell #1. In an implementation, the target control information may include one or more bits, and there is a mapping relationship between each bit and one Scell or one Scell group. 
     In the above implementation, in a case that the dormancy indication information indicates that the first cell is dormant, the method further includes any one of the following (1) or (2). 
     (1) Switch to a dormant BWP of the first cell. 
     For example, assuming that the first cell is an Scell #1, the second cell is a Pcell, the target control information may include one or more bits, and there is a mapping relationship between each bit and one Scell or one Scell group, in the implementation, when the Scell #1 or an Scell group to which the Scell #1 belongs is instructed to be dormant, the Scell #1 can no longer schedule the Pcell, and the terminal switches to the dormant BWP of the Scell #1. 
     (2) Skip switching to the dormant BWP of the first cell, and/or switch to a BWP of the first cell that cannot be used to schedule the second cell. In this case, the first cell may be configured with the dormant BWP or the first cell may also not be configured with the dormant BWP, that is, because the first cell is not configured with the dormant BWP, the terminal may skip switching to the dormant BWP of the first cell, and/or switch to the BWP of the first cell that cannot be used to schedule the second cell. In some embodiments, even though the first cell is configured with the dormant BWP, the terminal may also skip switching to the dormant BWP of the first cell, and/or switch to a BWP of the first cell that cannot be used to schedule a primary cell. 
     In the above (2), in some embodiments, the terminal may first determine to skip switching to the dormant BWP of the first cell, and further, the terminal may select to switch to the BWP of the first cell that cannot be used to schedule the second cell. In some embodiments, the terminal may also directly switch to or skip switching to the dormant BWP of the first cell. In some embodiments, the terminal may determine whether to skip switching to the dormant BWP of the first cell, and whether to switch the BWP and to switch to which BWP is not limited in this embodiment. 
     For example, assuming that the first cell is an Scell #1, the second cell is a Pcell, the target control information may include one or more bits, and there is a mapping relationship between each bit and one Scell or one Scell group, in the implementation, when the Scell #1 or an Scell group to which the Scell #1 belongs is instructed to be dormant, the Scell #1 can no longer schedule the Pcell, and the terminal does not switch to the dormant BWP of the Scell #1 (where the Scell #1 may be configured with the dormant BWP, or may not be configured with the dormant BWP). In some embodiments, the terminal may switch to a BWP of the Scell #1 that cannot be used to schedule the Pcell, and the BWP may be stipulated in a protocol, or may be configured by the network side. 
     In an implementation, after the receiving target control information on a target cell, the method further includes: determining, in a case that the dormancy indication information indicates that the first cell is non-dormant, that the first cell can schedule the second cell. 
     For example, assuming that the first cell is an Scell #1, the second cell is a Pcell, the target control information may include one or more bits, and there is a mapping relationship between each bit and one Scell or one Scell group, in the implementation, when the Scell #1 or an Scell group to which the Scell #1 belongs is instructed to be non-dormant (for example, a corresponding bit=1), the Scell #1 may schedule the Pcell, which is equivalent to activating a function of scheduling the Pcell by the Scell #1. 
     In another implementation, after the receiving target control information on a target cell, the method may further include: switching to a first target BWP of the first cell in a case that the dormancy indication information indicates that the first cell is non-dormant, where the first target BWP is a non-dormant BWP. The first target BWP may be configured by the network side. 
     In the above implementation, after the switching to a first target BWP of the first cell, the method may further include: determining, in a case that the first target BWP can be used to schedule the second cell, that the first cell can schedule the second cell; and determining, in a case that the first target BWP cannot be used to schedule the second cell, that the first cell cannot schedule the second cell. That is, in the implementation, in a case that the first target BWP may be used to schedule the second cell, the first cell may schedule the second cell, and in a case that the first target BWP cannot be used to schedule the second cell, the first cell cannot schedule the second cell. 
     For example, assuming that the first cell is an Scell #1 and the second cell is a Pcell, in a case that the non-dormant BWP (namely, the first target BWP) that is switched to is a BWP that may be used to schedule the Pcell, the Scell #1 may schedule the Pcell, that is, a function of scheduling the Pcell by the Scell #1 is activated; and in a case that the non-dormant BWP (namely, the first target BWP) that is switched to is a BWP that cannot be used to schedule the Pcell, the Scell #1 cannot schedule the Pcell. 
     In some embodiments, the first target BWP is a BWP that can be used to schedule the second cell. For example, when the network side configures the first target BWP, the first target BWP may be configured as a BWP that may be used to schedule the second cell. 
     In another implementation, after the receiving target control information on a target cell, the method further includes: switching to a second target BWP of the first cell in a case that the dormancy indication information indicates that the first cell is non-dormant, where the second target BWP is a BWP that can be used to schedule the second cell. That is, in the optional implementation, in a case that the dormancy indication information indicates that the first cell is non-dormant, the terminal directly switches to a BWP that is configured by the network side and may be used to schedule the second cell. 
     For example, assuming that the first cell is an Scell #1, the second cell is a Pcell, the target control information may include one or more bits, and there is a mapping relationship between each bit and one Scell or one Scell group, in the implementation, when the Scell #1 or an Scell group to which the Scell #1 belongs is instructed to be non-dormant (for example, a corresponding bit=1), the Scell #1 may schedule the Pcell, and the Scell #1 may be switched to a BWP that is configured by a base station and is used to schedule the Pcell. 
     In this embodiment of this application, the terminal may further determine relevant behaviors related to the second cell according to content of the dormancy indication information. The following separately describes cases according to the content of the dormancy indication information. 
     In an implementation, after the receiving target control information on a target cell, in a case that the dormancy indication information indicates that the first cell is dormant, the method further includes at least one of the following (1) to (3). 
     (1) Determine that the second cell can only schedule itself. 
     It should be noted that, in this embodiment of this application, that a cell can only schedule itself is for a scheduling capability of the cell. For example, that the second cell can only schedule itself means that in a case that the dormancy indication information indicates that the first cell is dormant, a scheduling capability of the second cell is that the second cell can only schedule itself, and cannot be scheduled by another cell. 
     In some embodiments, in a case that the dormancy indication information indicates that the first cell is dormant, a dormancy valid time of the first cell may be set within a certain time or after a certain time. Therefore, that the second cell can only schedule itself may be valid within a dormancy period of the first cell. Therefore, the determining that the second cell can only schedule itself may include: determining, within a first predetermined time or after a second predetermined time after receiving the target control information, that the second cell can only schedule itself. The optional implementation is equivalent to temporarily deactivating a function of scheduling the second cell by the first cell. Specific values of the first predetermined time and the second predetermined time may be determined according to a communication system that is actually applied, and are not limited in this embodiment. 
     (2) Determine, in a case that the target control information is on the first cell, that control information on the second cell can carry the dormancy indication information. 
     That is, in a case that the target control information is transmitted on the first cell, because the target control information indicates that the first cell is dormant, it is possible that the target control information cannot be transmitted on the first cell in a subsequent time. Therefore, a function of indicating the dormancy indication information by the second cell may be activated, and it may be determined that the control information on the second cell may carry the dormancy indication information. 
     In some embodiments, as described above, in a case that the dormancy indication information indicates that the first cell is dormant, the dormancy valid time of the first cell may be set within a certain time or after a certain time. Therefore, the determining that control information on the second cell can carry the dormancy indication information may include: determining, within a third predetermined time (which may be same as or different from the first predetermined time) or after a fourth predetermined time (which may be same as or different from the second predetermined time) after receiving the target control information, that the control information on the second cell can carry the dormancy indication information. The optional implementation is equivalent to temporarily activating a function of indicating the dormancy indication information by the second cell. Specific values of the third predetermined time and the fourth predetermined time may be determined according to a communication system that is actually applied, and are not limited in this embodiment. 
     (3) Determine, in a case that the target control information is on the second cell, that only the control information on the second cell can carry the dormancy indication information. 
     In some embodiments, as described above, in a case that the dormancy indication information indicates that the first cell is dormant, the dormancy valid time of the first cell may be set within a certain time or after a certain time. Therefore, the determining that only the control information on the second cell can carry the dormancy indication information may include: determining, within a fifth predetermined time (which may be same as or different from the first predetermined time) or after a sixth predetermined time (which may be same as or different from the second predetermined time) after receiving the target control information, that only the control information on the second cell can carry the dormancy indication information. 
     For example, assuming that the first cell is an Scell #1, the second cell is a Pcell, the target control information is DCI, one piece of DCI is transmitted on the Scell #1, and a bit corresponding to the Scell #1 or an Scell group to which the Scell #1 belongs in the DCI indicates 0 (that is, indicates dormant), (after/within a period of time) after the DCI is transmitted, the Pcell can only schedule itself, and/or DCI triggering or activating the Pcell may indicate a dormancy indication. For example, after/within a period of time, the DCI on the Pcell may indicate the dormancy indication, that is, in a case that a function of indicating the dormancy indication by the DCI on the Scell #1 is deactivated, a function of indicating the dormancy indication by the DCI on the Pcell is automatically activated. 
     That is, in an implementation of this embodiment of this application, it is allowed that the Scell #1 indicates that the Scell #1 (or the Scell group to which the Scell #1 belongs) is dormant, and in this case, scheduling of the Pcell cannot rely on the Scell #1. Therefore, the Pcell schedules itself. 
     In another example, assuming that the first cell is an Scell #1, the second cell is a Pcell, the target control information is DCI, one piece of DCI is transmitted on the Pcell, and a bit corresponding to the Scell #1 or an Scell group to which the Scell #1 belongs in the DCI indicates 0 (that is, indicates dormant), within/after a period of time after UE receives the DCI, the Pcell can only schedule itself, and/or only the DCI on the Pcell may indicate a dormancy indication. For example, within/after a period of time, the DCI on the Pcell may indicate the dormancy indication, that is, in a case that a function of indicating the dormancy indication by the DCI on the Scell #1 is deactivated, a function of indicating the dormancy indication by the DCI on the Pcell is automatically activated. 
     That is, in this embodiment of this application, it is allowed that the Pcell indicates that the Scell #1 (or the Scell group to which the Scell #1 belongs) is dormant, and in this case, scheduling of the Pcell cannot rely on the Scell #1. Therefore, the Pcell schedules itself. 
     In an implementation, in a case that the target control information may include one or more bits and there is a mapping relationship between each bit or each group of bits and one cell or one cell group, a corresponding order between each bit or each group of bits and the cell or the cell group may be: from left to right (or vice versa, that is, from right to left); or from low to high (or vice versa, that is, from high to low); or bit indicators (for example, indexes) from small to large (or vice versa, that is, from large to small) respectively corresponding to cells or cell groups whose indicators (for example, index) are from small to large (or vice versa, that is, from large to small). In some embodiments, a cell or a cell group corresponding to each bit or each group of bits may be one Scell or one Scell group. One group of bits may be explained as one field. 
     In the above implementations, in a case that the target control information on the first cell is DCI, a format of the target control information includes at least one of the following: 
     (1) A DCI format 1-1. 
     (2) A DCI format 0-1. 
     (3) A DCI format 2-6. 
     In a case that the first cell is configured with a common search space, the DCI format 2-6 may be used. That is, in a case that the DCI format 2-6 is used, it is required that the first cell is configured with the CSS. 
     In the above implementations, in a case that the target control information on the second cell is DCI, a format of the target control information includes at least one of the following (1) to (4). 
     (1) A DCI format 0-0. For example, in a case that the second cell still supports non-fallback DCI in this scenario, the DCI format 0-0 may be used on the second cell to indicate the dormancy indication information. 
     In some embodiments, when all bits in a frequency domain resource indication field (FDRA) of the target control information on the second cell are set as a preset value (for example, 0 or 1), the target control information carries the dormancy indication information. 
     In some embodiments, at least part of at least one of the following fields in DCI with the DCI format 0-0 is used for indicating the dormancy indication information: 
     a) an indication field of a modulation and coding scheme of a transport block 1; 
     b) an indication field of a new data indicator of the transport block 1; 
     c) an indication field of a redundancy version of the transport block 1; 
     d) an indication field of an HARQ process number; 
     e) an indication field of an antenna port; or 
     f) an indication field of DMRS sequence initialization. 
     By using an example in which the first cell is an Scell #1 and the second cell is a Pcell, bits corresponding to the dormancy indication information are ordered from left to right (or vice versa) or from low to high (or vice versa), or indexes of these bits from small to large (or vice versa) respectively correspond to Scells whose indexes are from small to large. In some embodiments, the above Scells are Scells other than the Scell #1. 
     (2) A DCI format 1-1. For example, in a case that the second cell still supports a terminal-specific search space (USS) in this scenario, that is, supports non-fallback DCI, the DCI format 1-1 may be used. 
     (3) A DCI format 0-1. For example, in a case that the second cell still supports a terminal-specific search space USS in this scenario, that is, supports non-fallback DCI, the DCI format 0-1 may be used. 
     (4) A DCI format 2-6. For example, in a case that the second cell still supports a common search space (CSS) in this scenario, the DCI format 2-6 may be used. 
     In the above implementation, in a case that the format of the target control information uses the DCI format 0-0, the terminal further sends feedback information after receiving the target control information on the target cell. 
     In some embodiments, the feedback information is used for indicating whether the terminal successfully receives the target control information. For example, the terminal sends confirmation (for example, ACK) feedback information in a case that the target control information is successfully received; otherwise, sends NACK. In some embodiments, the feedback information is used for indicating that the terminal successfully received the target control information. For example, the terminal sends the confirmation (for example, ACK) feedback information only in a case that the target control information is successfully received. 
     For example, in a case that DCI at a moment n, for example, the DCI format 0-0, indicates the dormancy indication, the terminal may send feedback information at a moment n+k or within a preset time window after the moment n. 
     In some embodiments, the feedback information may be HARQ-ACK, for example, ACK. In some embodiments, the feedback information may also be a MAC CE, for example, confirmation of the MAC CE. The MAC CE include a fixed quantity of ‘0’, and/or a carried logical channel number (LCID) is set to a value from 33 to 51, and in some embodiments, may be 43 or 45, or may be a value not being 43 or 45 from 33 to 51. 
     In some embodiments, k is a value stipulated in a protocol, or a value indicated by the DCI format 0-0, or a time of transmission of last piece of physical uplink shared information (PUSCH) from the moment n. 
     k may be a quantity of symbols, a quantity of slots, a quantity of subframes, or a quantity of frames. k may be represented by a preset subcarrier spacing (SCS), and the preset SCS is an SCS of the DCI format 0-0, or an SCS of a BWP on uplink (UL) of the Pcell, or an SCS of the above PUSCH, or a smallest one between at least two SCSs in these SCSs. 
     In some embodiments, n is a slot in which the DCI format 0-0 belongs, or is an end symbol or a start symbol of the DCI format 0-0. 
     By sending the above feedback information, it can be ensured that the terminal and a network-side device have the same understanding of whether the terminal receives the target control information, to prevent the terminal from being unable to accordingly perform dormancy or monitoring according to the dormancy indication of the target control information because the terminal loses the target control information, and prevent the network-side device from considering that the terminal receives the target control information and accordingly performing dormancy or monitoring according to the dormancy indication. 
     In the above implementations, information carried in the target control information includes any one of the following: the dormancy indication information and scheduled resource information; or the dormancy indication information. That is, in the implementations, the target control information may carry the dormancy indication information and the scheduled resource information, and may also carry other information (information other than the dormancy indication information and the scheduled resource information). In some embodiments, the target control information carries the dormancy indication information but does not carry the scheduled resource information, and may also carry the other information (the information other than the dormancy indication information and the scheduled resource information). The scheduled resource information may be scheduled resource information of the target control information. 
     In some embodiments, in a case that the target control information is target control information on the second cell and the second cell is configured with at least one of the following: a common search space, a terminal-specific search space, or specific DCI, the information carried in the target control information includes: the dormancy indication information and the scheduled resource information. 
     For example, in a case that the second cell supports the common search space and/or supports the terminal-specific search space, the information carried in the target control information includes: the dormancy indication information and the scheduled resource information. That is, in a case that the target control information is the target control information on the second cell and the second cell supports the common search space and/or supports the terminal-specific search space, in some embodiments, the target control information may carry the dormancy indication information and the scheduled resource information. 
     In some embodiments, in a case that the second cell can schedule itself through the specific DCI, the information carried in the target control information includes: the dormancy indication information and the scheduled resource information. 
     The specific DCI may include: the non-fallback DCI and/or the DCI with the DCI format 2-6. 
     In an implementation, in a case that the target control information is transmitted on the first cell and the dormancy indication information includes indication information corresponding to the second cell or the second cell group, the control information transmitted on the second cell does not carry the dormancy indication information, where the second cell group is a cell group to which the second cell belongs. That is, in the implementation, in a case that the dormancy indication information transmitted on the first cell indicates that the second cell is dormant, a function of indicating the dormancy indication information by the control information on the second cell is deactivated. In the implementation, although the control information on the second cell does not indicate the dormancy indication information, the terminal still needs to monitor a control channel on the second cell because the control information on the second cell may also carry other indication information. 
     For example, assuming that the first cell is an Scell #1 and the second cell is a Pcell, in a case that there is a correspondence between bit(s) in a dormancy indication of DCI on the Scell #1 and the Pcell, that is, the DCI includes indication information indicating whether the Pcell is dormant, a dormancy indication of DCI on the Pcell no longer indicates a function of the dormancy indication (which may be regarded as deactivation, but a PDCCH on the Pcell still needs to be monitored), and only the DCI on the Scell indicates the function of the dormancy indication. 
     In another implementation, in a case that the target control information is transmitted on the second cell and the dormancy indication information includes indication information corresponding to the second cell or the second cell group, it is determined that the control information on the second cell does not carry the dormancy indication information and/or the control information on the first cell carries the dormancy indication information within a predetermined time or after a predetermined time after receiving the target control information, where the second cell belongs to the second cell group. That is, in the implementation, within a seventh predetermined time or after an eighth predetermined time after receiving the target control information on the second cell, a function of indicating the dormancy indication information by the control information on the second cell is deactivated, and a function of indicating the dormancy indication information by the control information on the first cell is triggered or activated. The seventh predetermined time and the eighth predetermined time may be preset or configured by the network side, and are not specifically limited in this embodiment of this application. 
     For example, assuming that the first cell is an Scell #1 and the second cell is a Pcell, in a case that there is a correspondence between bit(s) in a dormancy indication of DCI on the Scell #1 and the Pcell, that is, the DCI includes indication information indicating whether the Pcell is dormant, within a predetermined time or after a predetermined time, a dormancy indication of DCI on the Pcell no longer indicates a function of the dormancy indication (which may be regarded as deactivation, but a PDCCH on the Pcell still needs to be monitored), and a function of indicating the dormancy indication by the DCI on the Scell is triggered or activated. 
     In the above implementation, in a case that the dormancy indication information carried in the target control information indicates that the second cell is dormant, it is determined that the second cell cannot schedule itself, or the second cell cannot schedule any cell. That is, in a case that the second cell is instructed to be dormant, the second cell cannot schedule itself but may schedule another cell, and the second cell is scheduled by the first cell, or the second cell cannot schedule any cell. Specific descriptions may be determined by a communication system that is actually applied, or stipulated in a protocol, and are not limited in this embodiment. 
     In the above implementation, the determining that the second cell cannot schedule itself, or the second cell cannot schedule any cell includes: determining that the second cell cannot schedule itself or the second cell cannot schedule any cell within a ninth predetermined time or after a tenth predetermined time after transmitting the target control information. The ninth predetermined time and the tenth predetermined time may be preset or configured by the network side, and are not specifically limited in this embodiment of this application. 
     As described above, in this embodiment of this application, the target control information may be transmitted on the first cell, or may be transmitted on the second cell, or may be transmitted on the first cell and the second cell. A specific implementation that is used may be determined according to a target configuration. Therefore, in an implementation, before the receiving target control information on a target cell, the method further includes: determining a target configuration of the target control information, where the target configuration includes at least one of the following (1) to (3). 
     (1) Receive the target control information on the first cell. 
     In some embodiments, when the second cell does not support a CSS or cannot be configured with a DCI format 2-6 or the DCI format 2-6 of the second cell is invalid, the target configuration may be used. 
     In some embodiments, when the second cell cannot schedule itself through specific non-fallback DCI (for example, a DCI format 1-1 or a DCI format 0-1), the target configuration may be used. 
     In some embodiments, when the second cell does not support the DCI format 2-6 and the specific non-fallback DCI (for example, the DCI format 1-1 or the DCI format 0-1), the target configuration may be used. 
     (2) Receive the target control information on the second cell. 
     In some embodiments, when the second cell supports the CSS or may be configured with the DCI format 2-6 or the DCI format 2-6 of the second cell is valid, the target configuration may be used. 
     In some embodiments, when the second cell supports the non-fallback DCI (for example, the DCI format 1-1 or the DCI format 0-1), the target configuration may be used. Further, when the second cell can schedule itself through the specific non-fallback DCI (for example, the DCI format 1-1 or the DCI format 0-1), the target configuration may be used. 
     In some embodiments, when the second cell supports the DCI format 2-6 and the specific non-fallback DCI (for example, the DCI format 1-1 or the DCI format 0-1), the target configuration may be used. 
     (3) Receive the target control information on the first cell and the second cell. 
     In an implementation, in different scenarios, by using an example in which the first cell is an Scell #1 and the second cell is a Pcell, in a case that the target control information is predetermined DCI, cases in which formats and/or types of predetermined DCI on the first cell and predetermined DCI on the second cell may be used simultaneously are shown in Table 1.

                 format 1-1 or DCI 
                 DCI format 0-1 
               
               
                   
                 format 0-1 
               
               
                   
               
            
           
         
       
     
     In an implementation, the determining a target configuration of the target control information may include: determining the target configuration according to configuration information and/or target information, where the target information includes at least one of the following: whether the target control information is configured; a format of the target control information; a type of the target control information; an indication manner of the target control information; or cell information of the target control information. 
     That is, in the above implementation, the target configuration may be determined according to the configuration information and/or the target information. 
     The configuration information may directly indicate the target configuration of the target control information, or the configuration information may also indirectly indicate the target configuration of the target control information. For example, the configuration information may indicate that the target control information is one or more of the above target configurations, for example, indicates indicators of three types of target configurations. For example, in a case that the above target configuration (2) is configured in the configuration information, the dormancy indication information is indicated by the target control information on the second cell. 
     In some embodiments, the configuration information may also indicate one or more of whether the target cell is configured with the target control information, the format of the target control information (for example, a format of DCI) configured with the target cell, the type of the target control information configured with the target cell, the indication manner of the target control information, or a cell in the target control information. Through the one or more information, the terminal may also determine the target configuration of the target control information. For example, in a case that only the target control information (for example, preset DCI) on the first cell is configured in the configuration information, only the target control information on the first cell may indicate the dormancy indication, that is, the target configuration is the above target configuration (1). 
     The above configuration information may be configured by the network side, or the network side may also not configure the configuration information. In this case, the terminal may determine the target configuration according to the above target information. For example, in a case that a format of the target control information configured with the first cell is the DCI format 1-1, the terminal may determine that the target configuration is the above target configuration (1). 
     In an implementation, the determining the target configuration according to configuration information and/or target information includes: selecting, in a case that multiple target configurations are determined according to the target information, one target configuration from the multiple target configurations according to at least one of the following: the target information; or priority information of the first cell and/or the second cell. In the implementation, when the target configuration is determined, in a case that the configuration information indicates the multiple target configurations, a target configuration corresponding to a cell with a high priority may be selected. For example, in a case that the first cell has a high priority, the above target configuration (1) is used. In another example, the target configuration configured in the configuration information is the above target configurations (1) and (2), and only the first cell is configured with the target control information. Therefore, it is determined that the target configuration is the above target configuration (1). 
     In another implementation, in a case that multiple target configurations are determined according to the target information, one target configuration is selected from the multiple target configurations according to the priority information of the first cell and/or the second cell. For example, both the first cell and the second cell are configured with the target control information, and in a case that the first cell has a high priority, the above target configuration (1) is used. 
     In the above implementation, after the target configuration of the target control information is determined, the target cell transmitting the target control information may be determined according to the target configuration. 
     In an implementation, the network side may configure the cell information of the target control information. Therefore, in the implementation, the method may further include: obtaining the cell information of the target control information, for example, receiving the cell information of the target control information transmitted by the network side. 
     In some embodiments, the cell information includes, but is not limited to at least one of the following: a cell type, a cell indicator, or a quantity of cells. 
     The cell type may include at least one of the following: a primary cell and/or a secondary cell, a scheduling cell and/or a scheduled cell, a cell scheduled by multiple cells and/or a cell scheduled by one cell, or a cell scheduled across carriers and/or a cell that schedules itself. The cell indicator may include: a serving cell index (servingcellindex) and/or a Physical Cell Identifier (PCI). The quantity of cells may be one or two (that is, both). 
     For example, in a case that the cell information is set as a ‘Pcell’ or the cell information is not configured, it is considered that target control information (for example, preset DCI) on the Pcell may indicate a dormancy indication. In a case that the cell information is configured as an ‘Scell’ or an ‘Scell #1’, it is considered that target control information on the Scell #1 may indicate the dormancy indication. In another example, in a case that the cell information is set as ‘both’ or ‘an Scell and an Pcell’, the Pcell and an Scell #1 include target control information. 
     In an implementation, in a case that the determined target configuration is the above target configuration (3), the target control information on the first cell and the second cell may indicate the dormancy indication information. In another implementation, a cell transmitting the target control information may also be determined according to a priority of the first cell and/or a priority of the second cell, that is, it is determined that the target control information is on the first cell or the second cell according to the priority of the first cell and/or the priority of the second cell. In some embodiments, the target control information on the two cells may also indicate the dormancy indication information. 
     The priority of the first cell and/or the priority of the second cell may be defined in a protocol or indicated by the network side. 
     For example, the protocol may define or the network side may indicate any one of the following: 
     (1) The second cell is preferred or the first cell is preferred. 
     (2) A cell using target control information (for example, the preset DCI) with a type of a group common PDCCH is preferred. 
     (3) A cell using target control information carrying the scheduled resource information and the dormancy indication information simultaneously is preferred. 
     (4) A cell configured with the target control information is preferred. 
     (5) A cell having target control information (for example, the preset DCI) with a small size (that is, the target control information includes a less quantity of bits) is preferred. 
     (6) A cell including different control information (for example, DCI) for scheduling the second cell with a small size is preferred. For example, in a case that a size of DCI on a Pcell scheduled by an Scell #1 is 3 bits and a size of DCI scheduled by the Pcell is one bit, the Pcell is preferred. 
     Alternatively, the network-side device may also indicate the priority of the first cell and/or the priority of the second cell, for example, the network-side device indicates that the second cell is preferred or indicates that the first cell is preferred. 
     In an implementation, the configuration information may further include: indication information indicating that the terminal does not expect that both the first cell and the second cell are configured with the target control information. In this case, in a case that the terminal does not expect to select the above target configuration (3) when determining the target configuration, if the network side configures the above target configuration (1) (or (2)) and the target configuration (3), the terminal selects the above target configuration (1) (or (2)). 
     In an implementation, before the receiving target control information on a target cell, the method may further include: obtaining indication information of the target control information, where the indication information is used for indicating at least one of the following information of the target control information: a format, a type, or carried information content. 
     For example, when the target control information is preset DC, a format of the preset DCI may be indicated as at least one of a DCI format 1-1, a DCI format 0-1, a DCI format 2-6, or a DCI format 0-0; and in some embodiments, may be the DCI format 1-1 and/or the DCI format 0-1. In some embodiments, a type of the preset DCI may be indicated as Fallback DCI: 0-0, Non-fallback DCI: 1-1/0-1, or DCI: 2-6 carried by a Group common PDCCH; and in some embodiments, may be specific Non-fallback DCI: the DCI format 1-1 and/or the DCI format 0-1. The information content carried in the target control information may be that: control resource information and the dormancy indication information are simultaneously carried, or the control resource information and the dormancy indication information are not simultaneously carried. For details, reference may be made to the above descriptions. Details are not described herein again. 
     In the above implementation, the network side determines whether the dormancy indication appears in the first cell or the second cell, so that the flexibility can be maintained, and overheads can also be reduced by instructing only one cell to indicate the dormancy indication. In some embodiments, only DCI 2-6 on the second cell is maintained to indicate the dormancy indication, and 1-1/0-1 for indicating the dormancy indication is on the first cell. 
     The above indication information may be configured by the network side, or may be stipulated in a protocol, or may be determined by the terminal. This is not specifically limited in this embodiment. 
     In the above implementation, the indication information is further used for indicating that: the terminal does not expect that the format and/or the type of the target control information configured by the first cell is same as the format and/or the type of the target control information configured by the second cell. For example, it is allowed that the Pcell has the DCI format 2-6 to indicate the dormancy indication, and the Scell #1 has the DCI format 1-1 or 0-1 that may indicate the dormancy indication. In some embodiments, it is allowed that the Pcell has the DCI format 0-0 to indicate the dormancy indication, and the Scell #1 has non-fallback DCI: the DCI format 1-1 or 0-1 that may indicate the dormancy indication. In some embodiments, it is not allowed that both the Pcell and the Scell #1 have the non-fallback DCI: the DCI format 1-1 or 0-1 that may indicate the dormancy indication. 
     In the above implementations, the first cell may be a secondary cell, and the second cell may be a primary cell.
