Description

[0001] This application is a divisional application. The application number of the original application is 201980100579.X, and the original application date is September 30, 2019. The entire contents of the original application are incorporated into this application by reference. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0003] In communication systems, the power consumption of terminal devices is an important aspect of user experience. The new radio (NR) standard 3GPP Release 16 (R16) proposes to reduce the power consumption of terminal devices. One way to reduce power consumption is to improve the mechanism of network device scheduling data, such as using cross-time slot scheduling to save power consumption of terminal devices. Figure 1 As shown, the network device schedules the physical downlink shared channel (PDSCH) to the terminal device through the physical downlink control channel (PDCCH). The time slot offset between the PDCCH and the scheduled PDSCH is greater than 0, that is, the PDCCH and the scheduled PDSCH are not in the same time slot. Compared with the time slot offset between the PDCCH and the scheduled PDSCH being 0, that is, the PDCCH and the scheduled PDSCH are in the same time slot, the terminal device only needs to receive and process the PDCCH in one time slot, without caching the PDSCH, and can relax the processing time of the PDCCH so that the device of the terminal device can reduce the clock frequency and voltage. Similarly, cross-time slot scheduling is adopted for the physical uplink shared channel (PUSCH), which will also achieve the effect of saving power consumption.

[0004] In the NR system, it supports configuring multiple downlink (DL) bandwidth parts (BWP) on each downlink carrier and multiple uplink (UL) BWP on each uplink carrier. The network device can configure multiple downlink BWPs on each downlink carrier and multiple uplink BWPs on each uplink carrier for the terminal device, and independently configure one or two minimum available time slot offsets (minimum K0) of PDSCH for each downlink BWP, and independently configure one or two minimum available time slot offsets (minimum K2) of PUSCH for each uplink BWP. However, at the same time, the terminal device has only one downlink BWP activated on a downlink carrier and only one uplink BWP activated on an uplink carrier. The network device can indicate the minimum K0 of the valid downlink BWP or the minimum K2 of the valid uplink BWP to the terminal device through DCI, and can also instruct the terminal device to switch the activated downlink BWP or uplink BWP through DCI. However, the existing technical solutions only indicate the effective minimum K0 of the downlink BWP or the effective minimum K2 of the uplink BWP of the terminal device, and are unable to simultaneously determine the effective minimum K0 of the downlink BWP and the effective minimum K2 of the uplink BWP of the terminal device. Therefore, a solution that can jointly indicate the minimum K0 and the minimum K2 is needed to simultaneously determine the effective minimum K0 of the downlink BWP and the effective minimum K2 of the uplink BWP of the terminal device. Summary of the invention

[0059] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0060] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as 5G systems, NR systems, long term evolution-advanced (LTE-A) systems and other communication systems, and can also be extended to cellular systems such as wireless fidelity (WiFi), worldwide interoperability for microwave access (WiMAX), and 3GPP, as well as future communication systems such as 6G systems. Specifically, taking the NR system as an example, the architecture of the communication system used in the embodiments of the present application can be as follows: Figure 2 As shown, the terminal device and the network device are included, and the terminal device and the network device perform downlink communication. It should be noted that this embodiment does not limit Figure 2 The number of terminal devices and network devices in the communication system shown.

[0061] Before introducing the embodiments of the present application, some terms in the present application are first explained to facilitate understanding by those skilled in the art.

[0062] 1) Terminal equipment, including equipment that provides voice and / or data connectivity to users, for example, may include a handheld device with wireless connection function, or a processing device connected to a wireless modem. The terminal equipment can communicate with the core network via a radio access network (RAN) and exchange voice and / or data with the RAN. The terminal equipment may include user equipment (UE), wireless terminal equipment, mobile terminal equipment, device-to-device (D2D) terminal equipment, V2X terminal equipment, machine-to-machine / machine-type communications (M2M / MTC) terminal equipment, Internet of Things (IoT) terminal equipment, subscriber unit, subscriber station, mobile station, remote station, access point (AP), remote terminal, access terminal, user terminal, user agent, or user equipment, etc. For example, it may include mobile phones (or "cellular" phones), computers with mobile terminal devices, portable, pocket-sized, handheld, and computer-built-in mobile devices, etc. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDA), and other devices. It also includes limited devices, such as devices with low power consumption, or devices with limited storage capacity, or devices with limited computing power, etc. For example, it includes information sensing devices such as barcodes, radio frequency identification (RFID), sensors, global positioning systems (GPS), laser scanners, etc.

[0063] As an example but not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable devices may also be referred to as wearable smart devices or smart wearable devices, etc., which are a general term for the application of wearable technology to intelligently design and develop wearable devices for daily wear, such as glasses, gloves, watches, clothing and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-size, and independent of smartphones to achieve complete or partial functions, such as smart watches or smart glasses, etc., as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets, smart helmets, and smart jewelry for vital sign monitoring.

[0064] The various terminal devices introduced above, if located on a vehicle (eg, placed in or installed in a vehicle), can be considered as vehicle-mounted terminal devices, which are also called on-board units (OBU).

[0065] In the embodiment of the present application, the terminal device may also include a relay. Alternatively, it can be understood that anything that can communicate data with the base station can be regarded as a terminal device.

[0066] 2) Network equipment, which may refer to equipment in an access network that communicates with a wireless terminal device through one or more cells at an air interface. The network equipment may be a node in a wireless access network, which may also be referred to as a base station, or a radio access network (RAN) node (or equipment). At present, some examples of network equipment are: gNB, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved NodeB, or home Node B, HNB), base band unit (BBU), or wireless fidelity (Wifi) access point (AP), etc. In addition, in a network structure, the network equipment may include a centralized unit (CU) node and a distributed unit (DU) node. CU implements some functions of gNB, and DU implements some functions of gNB. For example, CU is responsible for processing non-real-time protocols and services, and implementing the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers. DU is responsible for processing physical layer protocols and real-time services, and implementing the functions of the radio link control (RLC), media access control (MAC) and physical (PHY) layers.

[0067] 3) Existing cross-time slot scheduling process. The existing cross-time slot scheduling process mainly includes the following steps:

[0068] Step 1: The network device configures the time domain resource allocation list of PDSCH to the terminal device through radio resource control (RRC) signaling. The time domain resource allocation list of PDSCH includes a set of time slot offsets (K0) between PDCCH and the scheduled PDSCH, and a set of starting symbols and lengths of PDSCH in its time slot. The value of K0 in the K0 set can be greater than or equal to 0, and the value of K0 can be configured as one or more, such as the K0 set can be configured as {0, 1, 2, 3, 4, 5, 6}. At this time, the default minimum K0 = 0, that is, the K0 values ​​in the K0 set are all valid, and the PDCCH can indicate any K0 value in the K0 set when scheduling PDSCH, without restriction. The network device will also configure one or two minimum K0s to the terminal device through RRC signaling. Without loss of generality, if the network device is configured with only one minimum K0, the other minimum K0 value defaults to 0. For the sake of description, even if the network device does not configure only one minimum K0 value for the BWP, in the description of this application, the description "the network configures two minimum K2s" or "two configured minimum K2 values" is used. In this case, the two configured minimum K0 values ​​refer to minimum K0=0 and minimum K0=a value configured by RRC.

[0069] In addition, the network device will also configure the time domain resource allocation list of PUSCH to the terminal device through RRC signaling. The time domain resource allocation list of PUSCH includes a set of time slot offsets (K2) between PDCCH and the scheduled PUSCH, and a set of starting symbols and lengths of PUSCH in the time slot in which it is located. At this time, the default minimum K2=0, that is, all K2 values ​​in the K2 set are valid, and any K2 value in the K2 set can be indicated when PDCCH schedules PUSCH without restriction. The network device will also configure one or two minimum K2s to the terminal device through RRC signaling. Without loss of generality, if the network device is only configured with one minimum K2, the other minimum K2 value defaults to 0. For the sake of description, even if the network device does not configure only one minimum K2 value for the BWP, in the description of this application, descriptions such as "the network is configured with two minimum K2s" or "two configured minimum K2 values" are also used. In this case, the two configured minimumK2 values ​​refer to minimum K2=0 and minimum K2=one value configured by RRC.

[0070] Step 2: If two minimum K0s are configured in step 1, the network device sends a DCI to the terminal device via PDCCH to indicate one of the minimum K0s. For example, if the network device configures minimum K0=1,2 for the terminal device, the network device sends a DCI to the terminal device via PDCCH to indicate minimum K0=1. Both the network device and the terminal device will consider that the K0 in the K0 set that is less than the minimum K0 is invalid and cannot be used for scheduling, that is, the network device indicates minimum K0=1, and K0 cannot be less than 1 when PDCCH actually schedules PDSCH, that is, K0 cannot be 0.

[0071] If only one minimum K0 is configured in step 1, the DCI sent through PDCCH in step 2 indicates minimum K0, which indicates whether the downlink data scheduling is subject to the configured minimum K0. For example, in step 1, the network device only configures a minimum K0=1 for the terminal device, then step 2 indicates whether the downlink scheduling is subject to the minimum K0=1 constraint. If it is indicated as unconstrained, the default minimum K0=0 is used, and all values ​​in the K0 set are valid. If it is indicated as constrained, K0 should be greater than or equal to 1 in the actual scheduling.

[0072] Similarly, the network device may also send DCI to the terminal device via PDCCH to indicate one of the minimum K2s (two minimum K2s are configured), or to indicate whether uplink data scheduling is subject to the configured minimum K2 (one minimum K2 is configured).

[0073] In an embodiment of the present application, if minimum K0 or minimum K2 is configured with only one value, it is assumed that the minimum K0 or minimum K2 with an index of 0 in the minimum K0 set or the minimum K2 set is 0. Therefore, it is uniformly described as the network device sending a DCI to the terminal device through the PDCCH to indicate a minimum K0 in the minimum K0 set or a minimum K2 in the minimum K2 set.

[0074] Step 3: The network device schedules PDSCH to the terminal device through PDCCH. PDCCH will indicate a time slot offset value in the K0 set, and the time slot offset value must be greater than or equal to minimum K0. The terminal device will periodically monitor PDCCH. When minimum K0>0, the terminal device only needs to detect PDCCH and does not need to cache possible PDSCH in this time slot. The PDCCH processing time can be relaxed, thereby saving power consumption. If the terminal device detects that PDCCH schedules PDSCH, the terminal device receives PDSCH in the time slot corresponding to K0 indicated by PDCCH.

[0075] Similarly, for uplink data transmission, the network device schedules PUSCH to the terminal device through PDCCH. PDCCH indicates a time slot offset value in the K2 set, and the time slot offset value must be greater than or equal to minimum K2. When minimumK2>0, the terminal device only needs to detect PDCCH, which can relax the PDCCH processing time, thereby saving power consumption. If the terminal device detects that PDCCH schedules PUSCH, the terminal device receives PUSCH in the time slot corresponding to K2 indicated by PDCCH.

[0076] In addition, the communication system supports configuring multiple downlink BWPs on each downlink carrier and multiple uplink BWPs on each uplink carrier. The network device can configure multiple downlink BWPs on each downlink carrier and multiple uplink BWPs on each uplink carrier for the terminal device. However, at the same time, only one downlink BWP is activated on a downlink carrier and only one uplink BWP is activated on an uplink carrier. The network device can dynamically switch the activated downlink or uplink BWP through PDCCH. Take the downlink BWP as an example, Figure 3 As shown, the network device is configured with two BWPs. Currently, BWP1 is in an activated state. The terminal device monitors PDCCH on BWP1. When it detects that the BWP indicator field of DCI indicates BWP2 in the second time slot, the terminal device will switch to BWP2. At this time, the activated BWP switches from BWP1 to BWP2. After BWP2 is activated, the terminal device monitors PDCCH and receives PDSCH on BWP2.

[0077] In the case where the network device configures multiple downlink BWPs for each downlink carrier and multiple uplink BWPs for each uplink carrier to the terminal device, in step 1, the K0 set of each downlink BWP and the K2 set of each uplink BWP are independently configured, and the minimum K0 of each downlink BWP and the minimum K2 of each uplink BWP are also independently configured. The minimum K0 of different uplink BWPs or the minimum K2 of downlink BWPs may have different values. For example, downlink BWP#i with ID i is configured with two minimum K0s {minK0 DLBWP#i，0 , minK0 DLBWP#i，1}, the uplink BWP#x with ID x is also configured with two minimum K2{minK2 ULBWP#x，0 , minK2 ULBWP#x，1}.

[0078] Step (2) indicates that the currently valid minimum K0 and minimum K2 are minK0 and minK2 respectively. DLBWP#i，0 and minK2 ULBWP#x，0 When the downlink BWP switches from downlink BWP#i to downlink BWP#j, the effective minimum K0 on the newly activated downlink BWP#j is expressed as minK0 DLBWP#j，0 However, in the frequency division duplexing (FDD) system, the uplink BWP#x does not switch at this time. However, from the perspective of saving power consumption of the terminal device, there is a correlation between the effective minimum K0 of the downlink BWP of the terminal device and the effective minimum K2 of the uplink BWP. At this time, how to update the minimum K2 needs to be solved.

[0079] The present application aims to solve the problem that the prior art only indicates the valid minimum K0 of the downlink BWP or the valid minimum K2 of the uplink BWP of the terminal device, but cannot simultaneously determine the valid minimum K0 of the downlink BWP and the valid minimum K2 of the uplink BWP of the terminal device.

[0083] [Example 1]

[0084] Figure 4 A communication process diagram provided in an embodiment of the present application includes:

[0085] S401: A network device sends configuration information to a terminal device, and the terminal device receives the configuration information, where the configuration information includes at least one minimumK0 configured for at least one downlink BWP of the terminal device and at least one minimumK2 configured for at least one uplink BWP of the terminal device.

[0086] In the embodiment of the present application, there is a corresponding relationship between the minimumK0 configured by the network device for the downlink BWP of the terminal device and the minimumK2 configured for the uplink BWP of the terminal device.

[0087] In a possible implementation, the correspondence is that the minimumK0 of the downlink BWP configuration corresponds to the minimumK2 of the uplink BWP configuration one by one according to the index from small to large. For example, the minimum K0 with index 0 corresponds to the minimum K2 with index 0, and the minimum K0 with index 1 corresponds to the minimum K2 with index 1.

[0088] For example, the network device configures two minimum K0 {minK0 DLBWP#i，0 , minK0 DLBWP#i，1}, two minimum K0 {minK0 DLBWP#j，0 , minK0 DLBWP#j，1}; Two minimum K2 {minK2 ULBWP#x，0 , minK2 ULBWP#x，1}, two minimum K2 {minK2 ULBWP#y，0 , minK2 ULBWP#y，1}, where i, j, k, y in #i, #j, #x, #y represent the ID of the uplink / downlink BWP, minK0 DLBWP#i，0 、minK0 DLBWP#i，1 0 and 1 in etc. represent minK0 DLBWP#i，0 、minK0 DLBWP#i，1 Taking the downlink BWP#i and uplink BWP#x as an example, the minK0 with index 0 is DLBWP#i，0 Corresponding to minK2 with index 0 ULBWP#x，0 , minK0 with index 1 DLBWP#i，1 Corresponding to minK2 with index 1 ULBWP#x，1. In addition, when the network device configures only one minimum K0 for the downlink BWP of the terminal device or only one minimum K2 for the uplink BWP, it can be considered that the minimum K0 or minimum K2 corresponding to index 1 is the minimum K0 or minimum K2 configured by the network device, and the value of the minimum K0 or minimum K2 corresponding to index 0 is 0. Without loss of generality, the minimum K0 of index 0 and index 1 here can be determined according to preset rules. For example, in the high-level signaling, the first minimum K0 is the minimum K0 of index 0, and the second minimum K0 is the minimum K0 of index 1.

[0089] In addition, the correspondence between the minimumK0 configured by the network device for the downlink BWP of the terminal device and the minimumK2 configured for the uplink BWP of the terminal device can be included in the configuration information sent by the network device to the terminal device, and sent by the network device to the terminal device through the configuration information; it can also be defined through a protocol and pre-written into the network device and the terminal device.

[0090] As an example, the configuration information may be sent via a dedicated RRC message for the terminal device, or other RRC configuration messages.

[0091] S402: The network device sends DCI to the terminal device, and the terminal device receives the DCI.

[0092] The DCI includes indication information, and the indication information is used to indicate a minimumK0 in at least one minimumK0 of a downlink BWP configuration of the terminal device, or to indicate a minimumK2 in at least one minimumK2 of an uplink BWP configuration of the terminal device.

[0093] In one possible implementation, the DCI does not instruct the terminal device to switch the currently activated downlink BWP and uplink BWP. If the DCI is used to schedule downlink data, that is, the DCI is a downlink DCI, the indication information contained in the DCI is used to indicate a minimumK0 in the minimumK0 set of the downlink BWP currently activated by the terminal device; if the DCI is used to schedule uplink data, that is, the DCI is an uplink DCI, the indication information contained in the DCI is used to indicate a minimumK2 in the minimumK2 set of the uplink BWP currently activated by the terminal device.

[0094] For example, the DCI does not indicate that the terminal device switches the currently activated downlink BWP and uplink BWP, and is used to schedule downlink data. For example, the downlink DCI is used. The currently activated downlink BWP of the terminal device is downlink BWP#i, and the indication information contained in the DCI is 1, indicating that the {minK0 DLBWP#i，0 , minK0 DLBWP#i，1}minK0 with index 1 DLBWP#i，1 .

[0095] In another possible implementation, the DCI (actually the BWP indicator field of the DCI, which is also applicable to the following embodiments and will not be repeated herein) instructs the terminal device to switch the currently activated downlink BWP or uplink BWP. When the DCI instructs the terminal device to switch the activated downlink BWP to the downlink BWP to be activated, the DCI is used to schedule downlink data and is a downlink DCI. The indication information contained in the DCI is used to indicate a minimumK0 in the minimumK0 set of the downlink BWP to be activated. When the DCI instructs the terminal device to switch the activated uplink BWP to the uplink BWP to be activated, the DCI is used to schedule uplink data and is an uplink DCI. The indication information contained in the DCI is used to indicate a minimumK2 in the minimumK2 set of the uplink BWP to be activated.

[0096] For example, take DCI indicating that the terminal device switches the activated uplink BWP from the currently activated uplink BWP#x to the uplink BWP#y to be activated as an example, the DCI is used to schedule uplink data, which is an uplink DCI, and the indication information contained in the DCI is 0, indicating that the {minK2 ULBWP#y，0 , minK2 ULBWP#y，1 minK2 with index 0 in} ULBWP#y，0 .

[0097] S403: The network device and the terminal device determine, according to the DCI, a minimumK0 for a valid downlink BWP and a minimumK2 for a valid uplink BWP of the terminal device.

[0098] In an embodiment of the present application, when the DCI does not instruct the terminal device to switch the currently activated downlink BWP and uplink BWP, the network device and the terminal device determine the valid minimumK0 of the currently activated downlink BWP and the valid minimumK2 of the uplink BWP of the terminal device based on the DCI.

[0099] When the DCI instructs the terminal device to switch the activated uplink BWP from the currently activated downlink BWP to the downlink BWP to be activated, the network device and the terminal device determine, based on the DCI, the effective minimumK0 of the downlink BWP to be activated and the effective minimumK2 of the uplink BWP currently activated by the terminal device; when the DCI instructs the terminal device to switch the activated uplink BWP from the currently activated uplink BWP to the uplink BWP to be activated, the network device and the terminal device determine, based on the DCI, the effective minimumK0 of the downlink BWP currently activated by the terminal device and the effective minimumK2 of the uplink BWP to be activated.

[0100] That is, when the DCI instructs the terminal device to switch the currently activated downlink BWP or uplink BWP, the network device and the terminal device determine, based on the DCI, the effective minimumK0 of the uplink BWP currently activated by the terminal device and the effective minimumK2 of the downlink BWP after the terminal device switches to the uplink BWP or downlink BWP to be activated according to the DCI. In addition, the above description of determining the effective minimumK0 and minimumK2 of the uplink BWP and downlink BWP of the terminal device based on the DCI is also applicable to the following embodiments, and the repeated parts will not be repeated.

[0101] In one example, DCI is used to schedule downlink data, and does not instruct the terminal device to switch the currently activated downlink BWP and uplink BWP. The currently activated downlink BWP of the terminal device is downlink BWP#i, and the uplink BWP is uplink BWP#x. The indication information contained in the DCI is 1, indicating that {minK0 DLBWP#i，0 , minK0 DLBWP#i，1}minK0 with index 1 DLBWP#i，1 , the network device and the terminal device determine that the effective minimumK0 of the downstream BWP#i is minK0 DLBWP#i，1 At this time, no matter what the minimumK2 that was valid for the upstream BWP#x was, it is updated to the same value as minK0. DLBWP#i，1 There is a corresponding relationship between minK2 ULBWP#x，1 .

[0102] In another example, the currently activated downlink BWP of the terminal device is downlink BWP#i, and the uplink BWP is uplink BWP#x. The DCI indicates that the terminal device switches the currently activated uplink BWP#x to the uplink BWP#y to be activated. The DCI is used to schedule uplink data, which is an uplink DCI. The indication information contained in the DCI is 0, indicating that the {minK2 ULBWP#y，0 , minK2 ULBWP#y，1minK2 with index 0 in} ULBWP#y，0 , the network device and the terminal device determine that the effective minimumK2 of the uplink BWP#y is minK2 ULBWP#y，0 At this time, no matter what the minimumK0 that was valid for the downstream BWP#i was, it is updated to the same value as minK2 ULBWP#y，0 There is a corresponding relationship minK0 DLBWP#i，0 .

[0103] In a possible implementation, if the downlink BWP indicated by the indication information is not configured with minimumK0, or the uplink BWP indicated by the indication information is not configured with minimumK2, the minimumK0 valid for the downlink BWP and the minimumK2 valid for the uplink BWP may be determined in the following manner.

[0104] Method 1: Update the minimumK0 value valid for the downlink BWP of the terminal device and the minimumK2 value valid for the uplink BWP to 0 or the value corresponding to index 0. If the uplink BWP or downlink BWP is not configured with minimumK0 or minimumK2, the minimum K0 or minimumK2 value corresponding to index 0 is 0.

[0105] For example: the terminal device currently activates downlink BWP#i and uplink BWP#x, and the DCI instructs the terminal device to switch the currently activated downlink BWP#i to the downlink BWP#j to be activated, but the minimum K0 is not configured for the downlink BWP#j. Then the network device and the terminal device determine that the values ​​of the effective minimum K0 of the downlink BWP#j and the effective minimum K2 of the uplink BWP#x are both updated to 0, or are updated to the values ​​corresponding to index 0.

[0106] Method 2: If the DCI instructs the terminal device to switch the activated downlink BWP from the currently activated downlink BWP to the downlink BWP to be activated, or to switch the activated uplink BWP from the currently activated uplink BWP to the uplink BWP to be activated, the values ​​of the effective minimumK0 of the downlink BWP and the effective minimumK2 of the uplink BWP of the terminal device shall both use the effective minimumK0 and minimumK2 before or when receiving the DCI.

[0107] For example: the terminal device currently activates downlink BWP#i and uplink BWP#x, and the DCI instructs the terminal device to switch the currently activated uplink BWP#x to the uplink BWP#y to be activated, but the minimum K0 is not configured for BWP#y. The network device and the terminal device determine that the effective minimum K0 of downlink BWP#i still uses the effective minimum K0 of downlink BWP#i before or when DCI is sent or received, and the effective minimum K2 of uplink BWP#y uses the effective minimum K2 of uplink BWP#x before or when DCI is sent or received.

[0111] For example, at least one minimumK0 and minimumK2 combination configured by the network device for the downlink BWP#i of the terminal device includes: DLBWP#i，0 and minK2 DLBWP#i，0} and {minK0 DLBWP#i，1 and minK2 DLBWP#i，1}, the minimumK0 and minimumK2 combinations configured for downlink BWP#j include: {minK0 DLBWP#j，0 and minK2 DLBWP#j，0} and {minK0 DLBWP#j，1 and minK2 DLBWP#j，1}.

[0112] S502: The network device sends DCI to the terminal device, and the terminal device receives the DCI.

[0113] The DCI includes indication information, and the indication information is used to indicate one of at least one minimumK0 and minimumK2 combinations of the downlink BWP configuration of the terminal device.

[0114] In a possible implementation, when the DCI does not instruct the terminal device to switch the currently activated downlink BWP, the indication information is used to indicate one of at least one minimumK0 and minimumK2 combinations of the currently activated downlink BWP configuration of the terminal device.

[0115] In an embodiment of the present application, the DCI does not instruct the terminal device to switch the currently activated downlink BWP, including two situations: the DCI does not instruct the terminal device to switch the currently activated downlink BWP and uplink BWP, and the DCI instructs the terminal device to switch the currently activated uplink BWP to the uplink BWP to be activated.

[0116] That is to say, for the case where the DCI does not instruct the terminal device to switch the currently activated downlink BWP and uplink BWP, no matter whether the DCI is used to schedule uplink data or downlink data, that is, no matter whether the DCI is uplink DCI or downlink DCI, the indication information contained in the DCI is used to indicate one of the at least one minimumK0 and minimumK2 combinations of the downlink BWP configuration currently activated by the terminal device. When the DCI instructs the terminal device to switch the currently activated uplink BWP to the uplink BWP to be activated, although the DCI is used to schedule uplink data and is an uplink DCI, the indication information contained in the DCI is still used to indicate one of the at least one minimumK0 and minimumK2 combinations of the downlink BWP configuration currently activated by the terminal device.

[0117] In another possible implementation, when the downlink control information instructs the terminal device to switch the activated downlink BWP from the currently activated downlink BWP to the downlink BWP to be activated, the indication information is used to indicate one of at least one minimumK0 and minimumK2 combinations of the downlink BWP configuration to be activated.

[0118] S503: The network device and the terminal device determine, according to the DCI, a minimumK0 for a valid downlink BWP and a minimumK2 for a valid uplink BWP of the terminal device.

[0119] In a possible implementation, when the DCI does not instruct the terminal device to switch the currently activated downlink BWP and uplink BWP, the network device and the terminal device, based on the indication information contained in the DCI, combine a minimumK0 and a minimumK2 of the downlink BWP currently activated by the terminal device indicated by the indication information as the valid minimumK0 of the downlink BWP currently activated by the terminal device and the valid minimumK2 of the uplink BWP.

[0120] For example, the currently activated downlink BWP of the terminal device is downlink BWP#i, the currently activated uplink BWP is uplink BWP#x, and the minimumK0 and minimumK2 combinations configured for downlink BWP#i include: {minK0 DLBWP#i，0 and minK2DLBWP#i，0} and {minK0 DLBWP#i，1 and minK2 DLBWP#i，1}, the indication information contained in the DCI indicates the {minK0 DLBWP#i，0 and minK2 DLBWP#i，0} and {minK0 DLBWP#i，1 and minK2 DLBWP#i，1 {minK0} with index 1 in DLBWP#i，1 and minK2 DLBWP#i，1}, the network device and the terminal device determine that the effective minimumK0 of the downstream BWP#i is minK0 DLBWP#i，1 , the effective minimumK2 of the uplink BWP#x is minK2 DLBWP#i，1 .

[0121] In a possible implementation, when the DCI instructs the terminal device to switch the activated downlink BWP from the currently activated downlink BWP to the downlink BWP to be activated, the network device and the terminal device, based on the indication information contained in the DCI, combine a minimumK0 and a minimumK2 of the downlink BWP to be activated indicated by the indication information as the valid minimumK0 of the downlink BWP to be activated and the valid minimumK2 of the uplink BWP currently activated by the terminal device.

[0122] For example, the currently activated downlink BWP of the terminal device is downlink BWP#i, the currently activated uplink BWP is uplink BWP#x, the downlink BWP to be activated is downlink BWP#j, and the minimumK0 and minimumK2 combinations configured for downlink BWP#j include: {minK0 DLBWP#j，0 and minK2 DLBWP#j，0} and {minK0 DLBWP#j，1 and minK2 DLBWP#j，1}, the indication information contained in the DCI indicates the {minK0 DLBWP#j，0 and minK2 DLBWP#j，0} and {minK0 DLBWP#j，1 and minK2 DLBWP#j，1 {minK0} with index 0 in DLBWP#j，0 and minK2 DLBWP#j，0}, the network device and the terminal device determine that the effective minimumK0 of the downstream BWP#j is minK0 DLBWP#j，0 , the effective minimumK2 of the uplink BWP#x is minK2 DLBWP#j，0 .

[0123] In another possible implementation, when the DCI instructs the terminal device to switch the activated uplink BWP from the currently activated uplink BWP to the uplink BWP to be activated, the network device and the terminal device, based on the indication information contained in the DCI, combine a minimumK0 and a minimumK2 of the downlink BWP currently activated by the terminal device indicated by the indication information as the valid minimumK0 of the downlink BWP currently activated by the terminal device and the valid minimumK2 of the uplink BWP to be activated.

[0124] Optionally, for the case where the terminal device switches the currently activated uplink BWP to the uplink BWP to be activated, the minimum K2 valid for the uplink BWP to be activated needs to be converted according to the subcarrier spacing (SCS) of the uplink BWP to be activated. The subcarrier spacing size is expressed as 15*2^μkHz, μ=0, 1, 2, 3, 4. 15kHz can be considered as the baseline subcarrier spacing, μ is the scaling factor of the subcarrier spacing, and the minimum K2 valid for the uplink BWP to be activated is converted according to the ratio of the subcarrier spacing size. Among them, minimum K2 is the minimum K2 indicated by the indication information, μ_bwp1 is the scaling factor of the currently activated downlink BWP, and μ_bwp2 is the scaling factor of the uplink BWP to be activated. The minimumK2 valid for the uplink BWP to be activated is converted to match the slot length of different subcarrier spacings.

[0127] S601: A network device sends configuration information to a terminal device, and the terminal device receives the configuration information, where the configuration information includes at least one minimumK0 and minimumK2 combination configured for at least one uplink BWP of the terminal device.

[0128] For example, at least one minimumK0 and minimumK2 combination configured by the network device for the uplink BWP#x of the terminal device includes: uLBWP#x，0 and minK2 uLBWP#x，0} and {minK0 uLBWP#x，1 and minK2 uLBWP#x，1}, at least one minimumK0 and minimumK2 combination configured for uplink BWP#y includes: {minK0 uLBWP#y，0 and minK2 uLBWP#y，0} and {minK0 uLBWP#y，1 and minK2 uLBWP#y，1}.

[0129] S602: The network device sends DCI to the terminal device, and the terminal device receives the DCI.

[0130] The DCI includes indication information, and the indication information is used to indicate one of at least one minimumK0 and minimumK2 combinations of the uplink BWP configuration of the terminal device.

[0131] In a possible implementation, when the DCI does not instruct the terminal device to switch the currently activated uplink BWP, the indication information is used to indicate one of at least one minimumK0 and minimumK2 combinations of the currently activated uplink BWP configuration of the terminal device.

[0132] In an embodiment of the present application, the DCI does not instruct the terminal device to switch the currently activated uplink BWP, including two situations: the DCI does not instruct the terminal device to switch the currently activated downlink BWP and uplink BWP, and the DCI instructs the terminal device to switch the currently activated downlink BWP to the downlink BWP to be activated.

[0133] That is to say, for the case where the DCI does not instruct the terminal device to switch the currently activated downlink BWP and uplink BWP, no matter whether the DCI is used to schedule uplink data or downlink data, that is, no matter whether the DCI is uplink DCI or downlink DCI, the indication information contained in the DCI is used to indicate one of the at least one minimumK0 and minimumK2 combinations of the uplink BWP currently activated by the terminal device. When the DCI instructs the terminal device to switch the currently activated downlink BWP to the downlink BWP to be activated, although the DCI is used to schedule downlink data and is a downlink DCI, the indication information contained in the DCI is still used to indicate one of the at least one minimumK0 and minimumK2 combinations of the uplink BWP currently activated by the terminal device.

[0134] In another possible implementation, when the DCI instructs the terminal device to switch the activated uplink BWP from the currently activated uplink BWP to the uplink BWP to be activated, the indication information is used to indicate one of at least one minimumK0 and minimumK2 combinations of the uplink BWP configuration to be activated.

[0135] S603: The network device and the terminal device determine, according to the DCI, a minimumK0 for a valid downlink BWP and a minimumK2 for a valid uplink BWP of the terminal device.

[0136] In a possible implementation, when the DCI does not instruct the terminal device to switch the currently activated downlink BWP and uplink BWP, the network device and the terminal device, based on the indication information contained in the DCI, combine a minimumK0 and a minimumK2 of the uplink BWP currently activated by the terminal device indicated by the indication information as the valid minimumK0 of the downlink BWP currently activated by the terminal device and the valid minimumK2 of the uplink BWP.

[0137] For example, the currently activated downlink BWP of the terminal device is downlink BWP#i, the currently activated uplink BWP is uplink BWP#x, and the minimumK0 and minimumK2 combinations configured for uplink BWP#x include: {minK0 uLBWP#x，0 and minK2 uLBWP#x，0} and {minK0 uLBWP#x，1 and minK2 uLBWP#x，1}, the indication information contained in the DCI indicates the {minK0 uLBWP#x，0 and minK2 uLBWP#x，0} and {minK0 uLBWP#x，1 and minK2 uLBWP#x，1 {minK0} with index 1 in uLBWP#x，1 and minK2 uLBWP#x，1}, the network device and the terminal device determine that the effective minimumK0 of the downstream BWP#i is minK0 uLBWP#x，1 , the effective minimumK2 of the uplink BWP#x is minK2 uLBWP#x，1 .

[0138] In a possible implementation, when the DCI instructs the terminal device to switch the activated uplink BWP from the currently activated uplink BWP to the uplink BWP to be activated, the network device and the terminal device, based on the indication information contained in the DCI, use a minimumK0 and minimumK2 combination of the uplink BWP to be activated indicated by the indication information as the valid minimumK0 of the currently activated downlink BWP of the terminal device and the valid minimumK2 of the uplink BWP to be activated.

[0139] For example, the currently activated downlink BWP of the terminal device is downlink BWP#i, the currently activated uplink BWP is uplink BWP#x, the uplink BWP to be activated is uplink BWP#y, and the minimumK0 and minimumK2 combinations configured for uplink BWP#y include: {minK0 uLBWP#y，0 and minK2 uLBWP#y，0} and {minK0 uLBWP#y，1 and minK2 uLBWP#y，1}, the indication information contained in the DCI indicates the {minK0 uLBWP#y，0 and minK2 uLBWP#y，0} and {minK0 uLBWP#y，1 and minK2 uLBWP#y，1 {minK0} with index 0 in uLBWP#y，0 and minK2 uLBWP#y，0}, the network device and the terminal device determine that the effective minimumK0 of the downstream BWP#i is minK0 uLBWP#y，0 , the effective minimumK2 of the uplink BWP#y is minK2 uLBWP#y，0 .

[0140] In another possible implementation, when the DCI instructs the terminal device to switch the activated downlink BWP from the currently activated downlink BWP to the downlink BWP to be activated, the network device and the terminal device, based on the indication information contained in the DCI, combine a minimumK0 and a minimumK2 of the uplink BWP currently activated by the terminal device indicated by the indication information as the valid minimumK0 of the downlink BWP to be activated and the valid minimumK2 of the uplink BWP currently activated by the terminal device.

[0141] Optionally, when the terminal device switches the currently activated downlink BWP to the downlink BWP to be activated, the minimum K0 valid for the downlink BWP to be activated needs to be converted according to the SCS of the downlink BWP to be activated. The subcarrier spacing size is expressed as 15*2^μkHz, μ=0, 1, 2, 3, 4. 15kHz can be considered as the baseline subcarrier spacing, μ is the scaling factor of the subcarrier spacing, and the minimum K0 valid for the downlink BWP to be activated is converted according to the ratio of the subcarrier spacing size. Among them, minimum K0 is the minimum K0 indicated by the indication information, μ_bwp1 is the proportional factor of the downlink BWP activated before BWP switching, and μ_bwp2 is the proportional factor of the downlink BWP activated after BWP switching. The minimumK0 valid for the downlink BWP to be activated will be modified.

[0143] Figure 7 A communication process diagram provided in an embodiment of the present application includes:

[0144] S701: The network device sends configuration information to the terminal device, and the terminal device receives the configuration information, wherein the configuration information includes at least one minimumK0 and minimumK2 combination configured for at least one downlink BWP of the terminal device, and at least one minimumK0 and minimumK2 combination configured for at least one uplink BWP of the terminal device.

[0145] For example, at least one minimumK0 and minimumK2 combination configured by the network device for the downlink BWP#i of the terminal device includes: DLBWP#i，0 and minK2 DLBWP#i，0} and {minK0 DLBWP#i，1 and minK2 DLBWP#i，1}, the minimumK0 and minimumK2 combinations configured for downlink BWP#j include: {minK0 DLBWP#j，0 and minK2 DLBWP#j，0} and {minK0 DLBWP#j，1 and minK2 DLBWP#j，1}; At least one minimumK0 and minimumK2 combination configured for uplink BWP#x includes: {minK0 uLBWP#x，0 and minK2 uLBWP#x，0} and {minK0 uLBWP#x，1 and minK2 uLBWP#x，1}, at least one minimumK0 and minimumK2 combination configured for uplink BWP#y includes: {minK0 uLBWP#y，0 and minK2 uLBWP#y，0} and {minK0 uLBWP#y，1 and minK2 uLBWP#y，1}.

[0146] S702: The network device sends DCI to the terminal device, and the terminal device receives the DCI.

[0147] The DCI includes indication information, and the indication information is used to indicate one of at least one minimumK0 and minimumK2 combinations of the downlink BWP configuration of the terminal device, or to indicate one of at least one minimumK0 and minimumK2 combinations of the uplink BWP configuration of the terminal device.

[0148] In one possible implementation, the DCI does not instruct the terminal device to switch the currently activated downlink BWP and uplink BWP. If the DCI is used to schedule downlink data, that is, the DCI is a downlink DCI, the indication information is used to indicate one of at least one minimumK0 and minimumK2 combinations of the downlink BWP configuration currently activated by the terminal device; if the DCI is used to schedule uplink data, that is, the DCI is an uplink DCI, the indication information is used to indicate one of at least one minimumK0 and minimumK2 combinations of the uplink BWP configuration currently activated by the terminal device.

[0149] In another possible implementation, the DCI instructs the terminal device to switch the currently activated downlink BWP or uplink BWP. When the DCI instructs the terminal device to switch the activated downlink BWP from the currently activated downlink BWP to the downlink BWP to be activated, the DCI is used to schedule downlink data and is a downlink DCI. The indication information is used to indicate one of at least one minimumK0 and minimumK2 combinations configured for the downlink BWP to be activated. When the DCI instructs the terminal device to switch the activated uplink BWP from the currently activated uplink BWP to the uplink BWP to be activated, the DCI is used to schedule uplink data and is an uplink DCI. The indication information is used to indicate one of at least one minimumK0 and minimumK2 combinations configured for the uplink BWP to be activated.

[0150] S703: The network device and the terminal device determine, according to the DCI, a minimumK0 for a valid downlink BWP and a minimumK2 for a valid uplink BWP of the terminal device.

[0151] In a possible implementation, when the indication information indicates one of at least one minimumK0 and minimumK2 combinations of the downlink BWP configuration of the terminal device, the network device and the terminal device use the minimumK0 indicated by the indication information as the valid minimumK0 for the downlink BWP of the terminal device, and determine the minimumK2 that is the same as or closest to the minimumK2 indicated by the indication information in at least one minimumK0 and minimumK2 combination of the uplink BWP configuration of the terminal device as the valid minimumK2 for the uplink BWP of the terminal device.

[0152] For example, the currently activated downlink BWP of the terminal device is downlink BWP#i, the currently activated uplink BWP is uplink BWP#x, the downlink BWP to be activated is downlink BWP#j, and the minimumK0 and minimumK2 combinations configured for downlink BWP#j include: {minK0 DLBWP#j，0 and minK2 DLBWP#j，0} and {minK0 DLBWP#j，1 and minK2 DLBWP#j，1 The minimumK0 and minimumK2 combinations configured for uplink BWP#x include: {minK0 uLBWP#x，0 and minK2 uLBWP#x，0} and {minK0 uLBWP#x，1 and minK2 uLBWP#x，1}, the indication information contained in the DCI indicates the {minK0 DLBWP#j，0 and minK2 DLBWP#j，0} and {minK0 DLBWP#j，1 and minK2 DLBWP#j，1 {minK0} with index 0 in DLBWP#j，0 and minK2 DLBWP#j，0}, the network device and the terminal device determine that the minimumK0 valid for the downstream BWP#j is minK0 DLBWP#j，0 , the effective minimumK2 of the uplink BWP#x is minK2 uLBWP#x，0 、minK2 uLBWP#x，1 Zhong and minK2 DLBWP#j，0 The same or closest value.

[0153] In a possible implementation, when the indication information indicates one of at least one minimumK0 and minimumK2 combinations configured for the uplink BWP of the terminal device, the network device and the terminal device use the minimumK2 indicated by the indication information as the valid minimumK2 for the uplink BWP of the terminal device, and determine the minimumK0 that is the same as or closest to the minimumK0 indicated by the indication information in at least one minimumK0 and minimumK2 combination configured for the downlink BWP of the terminal device as the valid minimumK0 for the downlink BWP of the terminal device.

[0154] For example, the currently activated downlink BWP of the terminal device is downlink BWP#i, the currently activated uplink BWP is uplink BWP#x, the uplink BWP to be activated is uplink BWP#y, and the minimumK0 and minimumK2 combinations configured for uplink BWP#y include: {minK0 uLBWP#y，0 and minK2 uLBWP#y，0} and {minK0uLBWP#y，1 and minK2 uLBWP#y，1}、The minimumK0 and minimumK2 combinations configured for downlink BWP#i include: {minK0 DLBWP#i，0 and minK2 DLBWP#i，0} and {minK0 DLBWP#i，1 and minK2 DLBWP#i，1}, the indication information contained in the DCI indicates the {minK0 uLBWP#y，0 and minK2 uLBWP#y，0} and {minK0 uLBWP#y，1 and minK2 uLBWP#y，1 {minK0} with index 0 in uLBWP#y，0 and minK2 uLBWP#y，0}, the network device and the terminal device determine that the minimumK2 valid for the uplink BWP#y is minK2 uLBWP#y，0 , the minimumK0 valid for downlink BWP#i is minK0 DLBWP#i，0 、minK0 DLBWP#i，1 Medium and minK0 uLBWP#y，0 The same or closest value.

[0156] Figure 8 A communication process diagram provided in an embodiment of the present application includes:

[0157] S801: A network device sends configuration information to a terminal device, and the terminal device receives the configuration information, where the configuration information includes at least one minimumK0 and minimumK2 combination configured for at least one downlink BWP and uplink BWP pair of the terminal device.

[0158] For example, the minimumK0 and minimumK2 combinations configured by the network device for pairing the downlink BWP#i and uplink BWP#x of the terminal device include: DLBWP#i，0 and minK2 ULBWP#x，0} and {minK0 DLBWP#i，1 and minK2 ULBWP#x，1}, the minimumK0 and minimumK2 combinations configured for the pairing of downlink BWP#j and uplink BWP#x of the terminal device include: {minK0 DLBWP#j，0 and minK2 ULBWP#x，0} and {minK0 DLBWP#j，1 and minK2 ULBWP#x，1}, the minimumK0 and minimumK2 combinations configured for the pairing of downlink BWP#i and uplink BWP#y of the terminal device include: {minK0 DLBWP#i，0 and minK2 ULBWP#y，0} and {minK0 DLBWP#i，1 and minK2 ULBWP#y，1}, the minimumK0 and minimumK2 combinations configured for the pairing of downlink BWP#j and uplink BWP#y of the terminal device include: {minK0 DLBWP#j，0 and minK2 ULBWP#y，0} and {minK0 DLBWP#j，1 and minK2 ULBWP#y，1}.

[0159] S802: The network device sends DCI to the terminal device, and the terminal device receives the DCI.

[0160] The DCI includes indication information, and the indication information is used to indicate one of at least one minimumK0 and minimumK2 combinations of the downlink BWP and uplink BWP pairing configuration of the terminal device.

[0161] In a possible implementation, when the downlink control information does not instruct the terminal device to switch the currently activated uplink BWP and downlink BWP, the indication information is used to indicate one of at least one minimumK0 and minimumK2 combinations of the currently activated downlink BWP and uplink BWP pairing configuration of the terminal device.

[0162] In a possible implementation, when the downlink control information instructs the terminal device to switch the activated downlink BWP from the currently activated downlink BWP to the downlink BWP to be activated, the indication information is used to indicate one of at least one minimumK0 and minimumK2 combinations of the pairing configuration of the downlink BWP to be activated and the uplink BWP currently activated by the terminal device.

[0163] For example, the terminal device currently activates downlink BWP#i and uplink BWP#x, and the network device instructs the terminal device through a downlink DCI to switch the currently activated downlink BWP#i to downlink BWP#j, and the indication information contained in the DCI indicates one of at least one minimumK0 and minimumK2 combinations of the pairing configuration of downlink BWP#j and uplink BWP#x.

[0164] In a possible implementation, when the downlink control information instructs the terminal device to switch the activated uplink BWP from the currently activated uplink BWP to the uplink BWP to be activated, the indication information is used to indicate one of at least one minimumK0 and minimumK2 combinations of the pairing configuration of the currently activated downlink BWP of the terminal device and the uplink BWP to be activated.

[0165] For example, the terminal device currently activates downlink BWP#i and uplink BWP#x, and the network device instructs the terminal device through an uplink DCI to switch the currently activated uplink BWP#x to uplink BWP#y. The indication information contained in the DCI indicates one of at least one minimumK0 and minimumK2 combinations configured for downlink BWP#i and uplink BWP#y.

[0166] S803: The network device and the terminal device determine, according to the DCI, a minimumK0 for a valid downlink BWP and a minimumK2 for a valid uplink BWP of the terminal device.

[0167] In an embodiment of the present application, when the downlink control information does not instruct the terminal device to switch the currently activated uplink BWP and downlink BWP, the network device and the terminal will, based on the indication information contained in the DCI, use a minimumK0 and minimumK2 combination of the downlink BWP and uplink BWP currently activated by the terminal device as indicated by the indication information as the minimumK0 valid for the uplink BWP currently activated by the terminal device and the minimumK2 valid for the downlink BWP.

[0168] When the downlink control information instructs the terminal device to switch the activated downlink BWP from the currently activated downlink BWP to the downlink BWP to be activated, the network device and the terminal, based on the indication information contained in the DCI, use a minimumK0 and minimumK2 combination of the indicated pairing of the downlink BWP to be activated and the uplink BWP currently activated by the terminal device as the minimumK0 valid for the downlink BWP to be activated and the minimumK2 valid for the uplink BWP currently activated by the terminal device.

[0169] For example, the terminal device currently activates downlink BWP#i and uplink BWP#x, and the network device instructs the terminal device to switch the currently activated downlink BWP#i to downlink BWP#j through the downlink DCI. The minimumK0 and minimumK2 combinations configured for pairing downlink BWP#j and uplink BWP#x include {minK0 DLBWP#j，0 and minK2 uLBWP#x，0} and {minK0DLBWP#j，1 and minK2 uLBWP#x，1}, the indication information included in the DCI indicates the {minK0 DLBWP#j，0 and minK2 uLBWP#x，0} and {minK0 DLBWP#j，1 and minK2 uLBWP#x，1 {minK0} with index 0 in DLBWP#j，0 and minK2 uLBWP#x，0}, the network device and the terminal device determine that the effective minimumK0 of the downstream BWP#j is minK0 DLBWP#j，0 , the effective minimumK2 of the uplink BWP#x is minK2 uLBWP#x，0 .

[0170] Similarly, when the downlink control information instructs the terminal device to switch the activated uplink BWP from the currently activated uplink BWP to the uplink BWP to be activated, the network device and the terminal, based on the indication information contained in the DCI, use a minimumK0 and minimumK2 combination of the currently activated downlink BWP of the terminal device and the uplink BWP to be activated as the minimumK0 valid for the currently activated downlink BWP of the terminal device and the minimumK2 valid for the uplink BWP to be activated.

[0171] In a possible implementation, if the minimumK0 and minimumK2 combination is not configured for a pairing of a certain uplink BWP and a certain downlink BWP of the terminal device, if the DCI instructs the terminal device to switch the activated downlink BWP from the currently activated downlink BWP to a certain downlink BWP to be activated, and the pairing of the downlink BWP after switching and the currently activated uplink BWP is not configured with the minimumK0 and minimumK2 combination, then the values ​​of the effective minimumK0 of the downlink BWP after switching and the effective minimumK2 of the currently activated uplink BWP are both rolled back to 0.
