For example, when the target handover is indicated by DCI for the scheduled cell, the size of the DCI may change. Therefore, for the same scheduled object in the same monitoring occasion, multiple DCIs with different sizes may appear, resulting in a relatively high complexity for the terminal to detect the DCI.

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0038] It should be noted that the technology described in the embodiments of this application is not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, and can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments of this application are often used interchangeably, and the described technology can be used in the above-mentioned systems and radio technologies, as well as in other systems and radio technologies. However, the following description describes the New Radio (NR) system for example purposes, and the NR term is used in most of the following descriptions, although these technologies can also be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

[0039] Figure 1A block diagram of a wireless communication system to which embodiments of the present application can be applied is shown. The wireless communication system includes a terminal 11 and a network-side device 12. Among them, the terminal 11 can also be referred to as a terminal device or a user terminal (User Equipment, UE). The terminal 11 can be a mobile phone, a tablet personal computer, a laptop computer or a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), a palm computer, a netbook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), etc. Terminal-side devices. Wearable devices include: bracelets, headphones, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present application. The network-side device 12 can be a base station or a core network. Among them, the base station can be referred to as a Node B, an evolved Node B, an access point, a Base Transceiver Station (BTS), a radio base station, a radio transceiver, a Basic Service Set (BSS), an Extended Service Set (Extended Service Set, ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a Transmitting Receiving Point (TRP), or some other suitable term in the art. As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0040] For the convenience of understanding, some contents related to the embodiments of the present application are described below:

[0041] I. Number of DCIs.

[0042] In the NR system, when the SCS of the scheduling cell and the scheduled cell is different, a monitoring occasion may contain N DCIs for scheduling the scheduled cell, where N is related to the subcarrier spacing SCS of the scheduled cell and / or the scheduling cell. For example, when scheduling the Physical Downlink Shared Channel (PDSCH) with a subcarrier spacing of 60 kHz on a certain cell within a monitoring occasion with a subcarrier spacing of 15 kHz, up to N DCIs for scheduling this cell can be received within this monitoring occasion. For example, if N = 2, then up to 2 DCIs can be received. Among them, the monitoring occasion can be a time slot, a monitoring occasion, or a span.

[0043] Second, the size of the DCI. The size of the DCI can be understood as the number of bits contained in the DCI.

[0044] The number of bits contained in the DCI can be the number of all bits contained in the DCI (such as information bits and redundant bits), or the number of information bits contained, or the total number of bits of all bits contained in the DCI and the bits of the Cyclic Redundancy Check (CRC).

[0045] The BWP can be switched through the DCI. For example, the DCI indicates a BWP ID different from the currently scheduled BWP. The DCI used to indicate the handover is simply referred to as the handover DCI. The resource indication field in the handover DCI is still calculated according to the bandwidth of the BWP before the handover, so that the size of the handover DCI for scheduling the same scheduled cell is the same as that of the DCI before the handover. Only after the handover DCI, the DCI for scheduling the BWP after the handover starts to determine the resource indication field based on the bandwidth of the BWP after the handover.

[0046] For example, DCI 1, DCI 2, and DCI 3 are all used to schedule cell 1. Among them, DCI 1 is used to schedule BWP1. Subsequently, the user receives DCI2, and the indication of BWP2 by this DCI 2 means that a handover has occurred and BWP2 is scheduled. At this time, the resource indication field in DCI 2 is still determined according to the bandwidth of BWP1. Then, when DCI 3 schedules BWP2 after DCI 2, its resource indication field is determined according to BWP2.

[0047] In summary, due to the BWP handover, the number of bits contained in DCI 1 and DCI 2 may be different from the number of bits contained in DCI 3. Therefore, the number of bits contained in multiple DCIs within the same monitoring occasion unit is different, resulting in a relatively high complexity for the terminal to detect the DCI. For this reason, the DCI detection method of this application is proposed.

[0048] The DCI detection method provided by the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings through specific embodiments and their application scenarios.

[0049] Please refer to Figure 2 , Figure 2 which is a flowchart of a DCI detection method provided by the embodiments of the present application. This method is applied to a terminal. As Figure 2 shown, it includes the following steps:

[0050] Step 201, determine the monitoring opportunity, where the monitoring opportunity includes DCI of at least one object;

[0051] Step 202, within the monitoring opportunity, detect the target downlink control information DCI of the target object, where the target object is one of the at least one object;

[0052] Among them, the target DCI satisfies the first rule and / or the second rule. The first rule is: the target DCI only includes the first DCI indicating the target handover; the second rule is: the target DCI includes the first DCI, the DCI size of the target DCI is the same, and / or the first DCI satisfies the preset position rule.

[0053] The above DCI size can be understood as the number of bits included in the DCI. The above target object includes: one of a cell, a cell group, a carrier, a carrier group, and an SL resource pool. Among them, a cell can be understood as a carrier, and a cell group can be understood as a carrier group. A cell group can be the cells within a cell group, or may be a group of specific cells, for example, a group of cells that can be scheduled by a DCI at the same time. The above target handover may include BWP handover, cell handover, carrier handover, cell group handover, carrier group handover, or sidelink (SL) resource pool handover.

[0054] It should be noted that in this embodiment, if the target handover is a BWP handover, the above object can be understood as a cell, a carrier, a cell group, or a carrier group; if the target handover is a resource pool handover, the object can be understood as a BWP, a cell, a carrier, a cell group, or a carrier group; if it is a carrier handover, the object can be understood as a terminal.

[0055] A monitoring opportunity can be called a control monitoring opportunity, for example, it can be a slot, a span, or a monitoring occasion. The above target DCI is used to schedule the target object, that is, the target DCI of the above target object can be understood as the target DCI used to schedule the target object.

[0056] For the above first rule, one or more first DCIs may be included. For example, if the target DCI includes N1 DCIs, then these N1 DCIs are all first DCIs. When there are multiple first DCIs, the sizes of these multiple first DCIs are the same. In this way, it can be ensured that there is only one type of DCI with the same DCI size within the same monitoring opportunity, thereby reducing the complexity of the terminal detecting the DCI.

[0057] For the above second rule, it can be understood that: the target DCI only includes one or at least two first DCIs, or the target DCI includes a first DCI and a second DCI. When the target DCI includes a first DCI and a second DCI, the size of the first DCI is the same as that of the second DCI. In this way, it can be ensured that there is only one type of DCI with the same DCI size within the same monitoring opportunity, thereby reducing the complexity of the terminal detecting the DCI. And / or, the first DCI satisfies a preset position rule. For example, the first DCI is the last transmitted DCI, or the first DCI is the last transmitted DCI among the DCIs whose sizes change before and after the handover, so as to ensure that the DCI size remains unchanged before and after the handover.

[0058] It should be understood that the above first DCI can be called a handover DCI, and the above second DCI is a DCI not used for handover, for example, other DCIs except the first DCI, and can also be called a non-handover DCI.

[0059] In this embodiment, when it is understood that the target DCI includes the first DCI and the DCI sizes of the target DCI are the same: when the target DCI includes a first DCI indicating a target handover and the number of DCIs included in the target DCI is greater than 1, after the target handover is completed, the size of the DCI included in the target DCI is equal to the size of the DCI included in the target DCI before the handover. The above target DCI may only include multiple first DCIs, or may include both a first DCI and a second DCI. In the case of including a second DCI, there may be one or more first DCIs. For example, if the target DCI includes N1 DCIs, then these N1 DCIs may all be first DCIs, or some may be first DCIs and some may be second DCIs.

[0060] It should be understood that there may be one or more objects for target handover within one monitoring opportunity. Among them, different objects may satisfy the same rule or different rules. For example, all objects for target handover satisfy the first rule and / or the second rule at the same time, or some objects satisfy the first rule, some objects satisfy the second rule, and some objects satisfy both the first rule and the second rule. The following embodiments illustrate the possible situations within one monitoring opportunity.

[0061] Case 1: There is only one first DCI within the monitoring opportunity; this DCI is used to perform target switching on a certain object.

[0062] Case 2: Within the monitoring opportunity, the number of objects for which target switching is performed is equal to the number of first DCIs, and the DCI that schedules the objects for which target switching is performed only includes one first DCI. That is, each first DCI corresponds to a different object.

[0063] Case 3: Within the monitoring opportunity, the number of objects for which target switching is performed is equal to the number of first DCIs. The number of first DCIs included in the DCI that schedules the objects for which target switching is performed is only 1, and the number of second DCIs included can be one or more. At this time, the first DCI and the second DCI satisfy at least one of the following: the DCI size included in the first DCI is the same as the DCI size included in the second DCI; the first DCI satisfies the preset position rule.

[0064] Case 4: Within the monitoring opportunity, the number of objects for which target switching is performed is less than the number of first DCIs. The DCI of some of the objects for which target switching is scheduled includes multiple first DCIs, and the number of second DCIs included can be one or more. At this time, the DCI size of the multiple first DCIs remains unchanged before and after multiple switches. That is to say, the sizes of the multiple first DCIs remain unchanged. The first DCI and the second DCI satisfy at least one of the following: the DCI size included in the first DCI is the same as the DCI size included in the second DCI; the first DCI satisfies the preset position rule.

[0065] Case 5: Within the monitoring opportunity, the number of objects for which target switching is performed is less than the number of first DCIs. The DCI of some of the objects for which target switching is scheduled only includes multiple first DCIs, and the DCI size of the multiple first DCIs remains unchanged before and after multiple switches. That is to say, the sizes of the multiple first DCIs remain unchanged.

[0066] In the embodiments of the present application, by setting that within the monitoring opportunity, the target DCI for detecting the target object satisfies the first rule and / or the second rule. The first rule is: the target DCI only includes the first DCI indicating target switching; the second rule is: the target DCI includes the first DCI, the DCI sizes of the target DCI are the same, and / or the first DCI satisfies the preset position rule. In this way, it can be ensured that there is only one DCI size within one monitoring opportunity, thereby reducing the complexity of the terminal detecting the DCI.

[0067] Optionally, in one embodiment, the step of detecting the target downlink control information DCI of the target object within the monitoring opportunity includes:

[0068] Within the monitoring opportunity, detect at least one first DCI of the target object;

[0069] Or,

[0070] During the monitoring time period, detect a first DCI and a second DCI of the target object, where the second DCI is used to indicate information other than the target handover.

[0071] For the case of detecting at least one first DCI of the target object during the monitoring time period, the number of first DCIs for scheduling the target object can be one or more. When the number of first DCIs is more than one, the sizes of the front and rear DCIs of multiple target handovers corresponding to the multiple first DCIs remain unchanged, that is, the sizes of the multiple first DCIs are the same.

[0072] For the case of detecting the first DCI and the second DCI of the target object during the monitoring time period, the number of first DCIs for scheduling the target object can be one or more, and the number of the second DCIs can also be one or more, which is not further limited herein. Optionally, when the number of first DCIs is more than one, the sizes of the front and rear DCIs of multiple target handovers corresponding to the multiple first DCIs remain unchanged, that is, the sizes of the multiple first DCIs are the same.

[0073] In this embodiment, when the target DCI includes the first DCI and the second DCI, the preset position rule includes at least one of the following:

[0074] The count information of the first DCI is greater than the count information of the second DCI;

[0075] The number of the first DCIs is M, and the M first DCIs are the last M DCIs in the target DCI arranged in a preset order, where M is a positive integer.

[0076] In this embodiment, by setting the count information of the first DCI to be greater than the count information of the second DCI, and / or the M first DCIs are the last M DCIs in the target DCI arranged in a preset order. For example, when performing one target handover, the value of M is 1, and when performing multiple target handovers, the value of M can be greater than 1, and the sizes of the DCIs before and after multiple handovers remain unchanged. Since the DCI for handover is used as the last transmitted DCI, the second DCI before handover and the second DCI after handover are in different monitoring time periods, thereby ensuring that the sizes of the DCIs included in one monitoring time period are the same.

[0077] Wherein, the count information may include any one of the following: the value of the downlink allocation index, the value of the sidelink allocation index.

[0078] The values of the downlink allocation index include: the value of the Count Downlink assignment index (cDAI) and / or the value of the Total Downlink assignment index (tDAI);

[0079] The values of the sidelink allocation index include: the value of the Count Sidelink assignment index (cSAI) and / or the value of the Total Sidelink assignment index (tSAI).

[0080] In this embodiment, the value of cDAI can be understood as the value of cDAI itself or the value corresponding to cDAI. For example, if cDAI includes 2 bits, the index value indicated by these 2 bits can be understood as the value of cDAI itself, and the value corresponding to the index value indicated by these 2 bits can be understood as the value corresponding to cDAI. For example, if cDAI includes 2 bits and the indicated index values are 0 / 1 / 2 / 3, which respectively correspond to the numbered values 1 / 2 / 3 / 4. Similarly, the value of tDAI can be understood as the value of tDAI itself or the value corresponding to tDAI; the value of cSAI can be understood as the value of cSAI itself or the value corresponding to cSAI; the value of tSAI can be understood as the value of tSAI itself or the value corresponding to tSAI.

[0081] Optionally, in one embodiment, when the target DCI is the sidelink SL DCI, the preset order is determined according to at least one of the following orders:

[0082] The size order corresponding to the time interval between the resource where the SL DCI is located and the first resource indicated by the SL DCI, where the first resource includes at least one of the resource where the first control signaling is located and the resource where the first Physical Sidelink Shared Channel (PSSCH) is located;

[0083] The position order corresponding to the first resource;

[0084] The size order corresponding to the time domain span of the resource where the control signaling is located;

[0085] The position order corresponding to the second resource indicated by the SL DCI, where the second resource includes at least one of the resource where the last control signaling is located and the resource where the last PSSCH is located;

[0086] The size order corresponding to the time domain span of the resources indicated by the SL DCI; for example, if the SL DCI schedules three PSCCH and / or PSSCH resources, the time domain span of the resources indicated by the SL DCI is the time domain span of the earliest PSCCH and / or PSSCH resource and the latest PSCCH and / or PSSCH resource. For example, if the early PSCCH and / or PSSCH resource is in slot 10 and the latest PSCCH and / or PSSCH resource is in slot 20, the time domain span can be understood as 10 slots

[0087] The position order corresponding to the third resource, where the third resource is the virtual feedback resource corresponding to the second resource;

[0088] The position order corresponding to the fourth resource, where the fourth resource is the feedback resource corresponding to the second resource;

[0089] The position order corresponding to the fifth resource, where the fifth resource is the reporting resource corresponding to the second resource;

[0090] The size order corresponding to the time offset between the fifth resource and the third resource;

[0091] The size order corresponding to the time offset between the fifth resource and the fourth resource;

[0092] The size order of the resource pool index indicated by the SL DCI;

[0093] The size order of the index of the target SL resource pool before handover.

[0094] In this embodiment, the above control signaling may include control information transmitted by a Physical Sidelink Control Channel (PSCCH), first-level Sidelink Control Information (SCI), or second-level Sidelink Control Information.

[0095] Among them, the first-level SCI can be understood as SCI format 1-A, and the second-level SCI can be understood as SCI format 2-x, such as SCI format 2-A or SCI format 2-B.

[0096] The time domain span of the resources indicated by the above SL DCI can be understood as the time domain span of all PSSCH transmission resources indicated by the SL DCI for scheduling.

[0097] It should be understood that the position of a certain resource can be understood as a time-frequency resource position, and the above position order can be understood as an arrangement order based on the starting position of the time-frequency resource or an arrangement order based on the ending position. For example, the position order corresponding to the first resource can be understood as an arrangement order based on the starting position or the ending position of the first resource. The starting position can be understood as the starting slot or the starting symbol, and the ending position can be understood as the ending slot or the ending symbol.

[0098] In one embodiment, assume that the target DCI transmitted during a certain monitoring opportunity includes DCI 1, DCI 2, and DCI 3, where the starting position of the first resource indicated by DCI 1 is slot 5, the starting position of the first resource indicated by DCI 2 is slot 2, and the starting position of the first resource indicated by DCI 3 is slot 3. Then, the target DCI arranged according to the above preset order can be understood as DCI 2, DCI 3, and DCI 1. That is to say, the target DCI includes three DCIs arranged in sequence as DCI 2, DCI 3, and DCI 1.

[0099] The position order corresponding to the fifth resource can be understood as: the starting position or the ending position order of the reporting resource corresponding to the target feedback resource, where the target feedback resource is the feedback resource corresponding to the last PSSCH and / or PSCCH transmission resource indicated by each SL DCI. Among them, the reporting resource can be a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH). The reporting resource position can be determined based on the position of the virtual feedback resource or the actual feedback resource position.

[0100] The above feedback resource can be a Physical Sidelink Feedback Channel (PSFCH) resource.

[0101] Regarding the size order of the resource pool index indicated by the SL DCI, it can be understood as: the size order of the pool index (pool index) indicated by each SL DCI or the pool identity (Identity, id) corresponding to the pool index or the pool id corresponding to the configured grant index indicated by each SL DCI.

[0102] The above size order can be understood as the size order of the indexes or the size order of the values corresponding to the indexes. For example, if the index of the time interval of the first resource indicated by the SL DCI is 2 and the value corresponding to this index is 10 slots, sorting can be performed based on this index or based on the value corresponding to this index. Further, this size order can be in descending order or ascending order, and no further limitation is made here.

[0103] Optionally, the virtual feedback resource corresponding to the second resource can be understood as follows: assuming that the SL timing is the same as the Uu timing, or assuming that the SL timing is the same as the downlink timing, or assuming that the SL timing is boundary-aligned with the Uu timing (such as frame or sub-frame or time slot or symbol boundary alignment), or assuming that the SL timing is boundary-aligned with the downlink timing (such as frame or sub-frame or time slot or symbol boundary alignment), the position of the feedback resource determined according to the second resource.

[0104] Optionally, the fourth resource can be understood as: the actual feedback resource of the second resource.

[0105] In one embodiment, the preset order is determined according to at least one of the following orders:

[0106] The size order of the semi-persistent scheduling (SPS) index;

[0107] The size order corresponding to the configured grant index;

[0108] The size order corresponding to the target control channel element (CCE) index, where the target CCE is the CCE with the largest or smallest index among all the CCEs occupied by the SL DCI;

[0109] The first index size order, where the first index is the index of the BWP, cell, carrier, cell group, or carrier group before the target handover;

[0110] The second index size order, where the second index is the index of the BWP, cell, carrier, cell group, or carrier group after the target handover.

[0111] In this embodiment, the above target DCI can be an SL DCI or a non-SL DCI, and no further limitation is made here. The above size order can be in descending order. For example, the larger the SPS index, the more forward the corresponding DCI; the above size order can also be in ascending order. For example, the larger the SPS index, the more backward the corresponding DCI. The SL DCI can be understood as: the DCI used to schedule or activate or deactivate the SL resources.

[0112] Optionally, after the step of detecting the target downlink control information (DCI) of the target object within the monitoring opportunity, the following steps are included:

[0113] Within the monitoring opportunity after the target handover, detect the DCI according to the size of the DCI detected before the target handover.

[0114] In this embodiment, the size of the DCI detected by the terminal remains unchanged, that is, the DCI is detected using the same DCI size within the same monitoring opportunity, thereby reducing the difficulty of the terminal detecting the DCI.

[0115] Optionally, in an embodiment, when the target handover is a BWP handover, the target object satisfies that the configuration of the first BWP is different from the configuration of the second BWP, where the first BWP is the BWP before the handover and the second BWP is the BWP after the handover.

[0116] In this embodiment, the fact that the configuration of the first BWP is different from the configuration of the second BWP can be understood as that the configuration of the BWP is different before and after the BWP handover. Among them, the difference in the BWP configuration can be understood as at least one of the following configurations being different: the carrier bandwidth where it is located, the BWP bandwidth, the frequency domain resource allocation method (such as type0 or type1), the frequency domain resource allocation, the time domain resource allocation, the frequency hopping method, the uplink indication (indicating whether to transmit on the uplink carrier or the supplementary uplink carrier), the number of transport blocks (TBs), the mapping method from virtual resource blocks (VRBs) to physical resource blocks (PRBs), the hybrid automatic repeat request (HARQ) feedback offset, the number of antenna ports, the sounding reference signal (SRS) configuration (such as SRS request, the number of SRS resources), the beta offset, the feedback codebook type (such as semi-static or dynamic codebook), the scheduling method, whether BWP handover is supported, the PRB bundle size, the rate matching resource configuration or indication, the channel state information reference signal (CSI-RS) configuration, the CSI-RS trigger or request, the quasi co-location (QCL) configuration, the code block group (CBG) configuration, and the precoding method.

[0117] Among them, the scheduling method can be understood to include self-scheduling or cross-carrier scheduling method, or single scheduling (one DCI schedules one cell) or multi-scheduling (one DCI schedules multiple cells), unicast scheduling, multicast scheduling or broadcast scheduling. The QCL configuration includes at least one of transmission configuration indication (TCI), the association relationship of Demodulation Reference Signal (DMRS), and the association relationship of SRS, etc.

[0118] The above HARQ feedback offset can be the feedback time offset from PDSCH to HARQ (PDSCH-to-HARQ_feedback time offset), or the feedback time offset from PSFCH to HARQ (PSFCH-to-HARQ_feedback time offset).

[0119] The above uplink indication can be used to indicate whether to transmit on the uplink carrier or the supplementary uplink (SUL) carrier.

[0120] The above QCL configuration including the transmission configuration indication can include at least one of the Synchronization Signal and PBCH block (SSB) for QCL reference, the index of CSI-RS, and the reference QCL type.

[0121] Optionally, the above BWP switching can include: uplink BWP switching, downlink BWP switching or sidelink BWP switching.

[0122] In another embodiment, for any target handover, the target object satisfies at least one of the following:

[0123] The subcarrier spacing SCS of the scheduling cell is different from the SCS of at least one cell in the target object;

[0124] The SCS of the scheduling cell is greater than the SCS of at least one cell in the target object;

[0125] The number of the first bits is different from the number of the second bits; the number of the first bits is the number of bits included in the DCI for scheduling the target object before the target handover, and the number of the second bits is the number of bits included in the DCI for scheduling the target object after the target handover; for example, the number of the first bits is the number of bits included in the DCI corresponding to the first BWP, and the number of the second bits is the number of bits included in the DCI corresponding to the second BWP. For example, the number of the first bits is the number of bits included in the DCI corresponding to the first resource pool, and the number of the second bits is the number of bits included in the DCI corresponding to the second resource pool.

[0126] The absolute value of the difference between the number of the first bits and the number of the second bits is greater than or equal to a first preset value;

[0127] N is greater than a second preset value, where N is the maximum number of DCIs for scheduling the target object allowed in the monitoring opportunity;

[0128] Q is greater than a third preset value, where Q is the maximum number of target DCIs for scheduling the target object allowed in the monitoring opportunity;

[0129] R is greater than a fourth preset value, where R is the maximum number of the first DCIs for scheduling the target object allowed in the monitoring opportunity;

[0130] T is greater than a fifth preset value, where T is the maximum number of second DCIs for scheduling the target object allowed in the monitoring opportunity, and the second DCI is used to indicate other information except the target handover.

[0131] Among them, the maximum number of target DCIs for scheduling the target object allowed in the monitoring opportunity can be understood as: the maximum number of SL DCIs for scheduling the target object allowed in the monitoring opportunity, the maximum number of uplink DCIs for scheduling the target object allowed in the monitoring opportunity, or the number of downlink DCIs for scheduling the target object allowed in the monitoring opportunity. The magnitudes of the above second preset value, third preset value, fourth preset value, and fifth preset value can be set according to actual needs. For example, in one embodiment, the above second preset value can be 1, the third preset value can be 1, the fourth preset value can be 0, and the fifth preset value can be 0.

[0132] For better understanding of the present application, the following takes the BWP handover of a cell as an example for detailed description.

[0133] Solution 1, if a handover DCI appears in the monitoring opportunity, only the handover DCI can exist in the monitoring opportunity.

[0134] Optionally, in one embodiment, in a monitoring occasion, there may be one or more non-switching DCIs, or there may be only one DCI indicating BWP switching on a certain cell. The certain cell may be any scheduled cell. In other words, in this embodiment, for the same scheduled cell in a monitoring occasion, if there is a DCI indicating BWP switching, then the DCI scheduling the scheduled cell only includes one switching DCI and does not include non-switching DCIs.

[0135] Optionally, in another embodiment, in a monitoring occasion, there may be one or more non-switching DCIs, or there may be one or more DCIs indicating BWP switching on a certain cell. In other words, in this embodiment, for the same scheduled cell in a monitoring occasion, if there is a DCI indicating BWP switching, then within this monitoring occasion, the DCI scheduling the scheduled cell only includes switching DCIs and does not include non-switching DCIs, and there may be one or more of these switching DCIs.

[0136] For example, in one embodiment, if there are multiple DCIs indicating BWP switching in a monitoring occasion, then these DCIs correspond to different scheduled cells. Suppose there are two switching DCIs within a monitoring occasion, then these two DCIs are respectively used for BWP switching on cell 1 and cell 2.

[0137] In another embodiment, if there are multiple DCIs indicating BWP switching in a monitoring occasion, these DCIs may correspond to the same scheduled cell.

[0138] As Figure 3 shown, in one embodiment, the terminal may receive L DCIs for scheduling cell 1 within a monitoring occasion. Suppose L = 2. After the terminal receives a DCI indicating BWP switching on cell 1 (i.e., DCI 1), the terminal expects or assumes that it will not receive other DCIs scheduling cell 1 within this monitoring occasion.

[0139] Solution 2, if a switching DCI appears in a monitoring occasion, there may also be non-switching DCIs, and the switching DCI is the last one among the DCIs corresponding to its scheduled cell or has the largest count information carried.

[0140] Optionally, when there are no non-switching DCIs, for the same scheduled cell in a monitoring occasion, if there is a DCI indicating BWP switching, then there is one DCI for this scheduled cell within this monitoring occasion, and it is the DCI indicating BWP switching.

[0141] Optionally, when there is non-switching DCI, for the same scheduled cell in a monitoring occasion, if there is DCI indicating BWP switching, then this DCI is the last DCI among the DCIs for this scheduled cell within this monitoring occasion or has the largest count information carried.

[0142] Optionally, the count information refers to the number and / or total number of DCIs. For example, in one embodiment, it can be the value of cDAI and / or the value of tDAI. In another embodiment, it can also be the value of cSAI and / or the value of tSAI.

[0143] As Figure 4 shown, in one embodiment, the terminal may receive L DCIs for scheduling cell 1 within a monitoring occasion. Assuming L = 2, after the terminal receives a DCI (i.e., DCI 2) indicating BWP switching for cell 1, the terminal expects or assumes that this DCI is the last DCI among the DCIs for cell 1 within this monitoring occasion, or the terminal expects or assumes that the count information carried by this switching DCI is greater than the count information carried by the non-switching DCI. For example, the DCI number carried by DCI 1 is 2, and the DCI number carried by DCI2 is 3.

[0144] Optionally, the above restrictions are only applicable to the case where the BWP configurations before and after switching are different.

[0145] Optionally, the above restrictions are only applicable to the case where the SCS of the scheduling cell and the scheduled cell are different.

[0146] Optionally, the above restrictions are only applicable to the case where the SCS of the scheduling cell and at least one of the scheduled cells in the scheduled cell group are different.

[0147] Optionally, the above restrictions are only applicable to the case where the SCS of the scheduling cell is greater than the SCS of the scheduled cell.

[0148] Optionally, the above restrictions are only applicable to the case where the SCS of the scheduling cell is greater than the SCS of at least one of the scheduled cells in the scheduled cell group.

[0149] Optionally, the above restrictions are only applicable to the case where the sizes of the DCIs corresponding to the BWP before and after switching for the same scheduled cell are different, or the difference in the sizes of the DCIs is not less than the preset number of bits.

[0150] Optionally, the above restrictions are only applicable to the case where N > 1, where N is the maximum number of DCIs allowed to schedule the target object within the monitoring occasion.
