FIELD OF TECHNOLOGY TO WHICH THE INVENTION RELATES

[0002] Embodiments of the present application relate to the field of communication technologies and, in particular, to a method and device for switching scheduling.

BACKGROUND OF THE INVENTION

[0003] In Rel-15 provided by the 3rd generation partnership project (3GPP), in order to schedule a terminal data channel, the base station first sends scheduling information and schedules the terminal data channel using the scheduling information (e.g., schedules the physical channel physical downlink shared channel (PDSCH) control of the terminal using PDSCH scheduling information that is sent via the physical downlink control channel (PDCCH) or schedules the physical downlink shared channel , PUSCH) of the terminal using the PUSCH scheduling information that is sent via the PDCCH). The scheduling information may indicate a data channel transmission parameter, such as the location of a data channel time domain resource. The terminal may receive the data channel at the data channel time domain resource location based on the indication of the scheduling information.

[0004] The above scheduling process may include the following two scheduling modes based on the time domain location relationship of the data channel and the PDCCH: single slot scheduling, where the PDCCH and the data channel are located in the same slot ; and scheduling between slots (cross-slot scheduling), where the data channel and PDCCH are located in different slots. For example, the terminal may receive a data channel in the next slot of the slot occupied by the PDCCH.

[0005] In order to reduce terminal power consumption and provide a good user experience, the 3rd generation partnership project (3GPP) initiates a terminal power reduction project in Rel-16 and discusses how to reduce power consumption. terminal through dynamic scheduling mode switching. For example, when scheduling the same slot, the terminal needs to activate the terminal's RF module in real time to ensure smooth transmission of the data link. When scheduling between slots before transmitting data over the data link, the terminal may turn off the radio frequency module of the terminal to reduce the power consumption of the terminal and save power for the terminal. However, how to specifically specify the terminal's scheduling mode and the application time of the scheduling mode has not been discussed.

SUMMARY OF THE INVENTION

[0006] Embodiments of the present application provide a scheduling switching method and an apparatus for indicating a terminal's scheduling mode switching and specifying when the scheduling mode is applied.

[0007] To achieve the above goal, the following technical solutions are used in the embodiments of the present application.

[0008] According to a first aspect, an embodiment of the present application provides a scheduling switching method. The terminal receives a switch indication which is sent by the network device and which is used to instruct the terminal to switch from the first scheduling mode to the second scheduling mode, and determines the application time of the second scheduling mode, so that the terminal schedules the data channel and/or starts the reference signal time using the second mode. scheduling when it is time to apply the second scheduling mode.

[0009] The switching indication may include one or more values of a minimum value K0, a minimum value K2, a minimum aperiodic CSI-RS trigger offset value, and a minimum aperiodic SRS trigger offset value. Alternatively, the switch indication may include one or more indexes. The index may be used to indicate a minimum K0 value, a minimum K2 value, a minimum aperiodic CSI-RS trigger offset value, or a minimum aperiodic SRS trigger offset value. K0 is the slot offset between the slot in which the PDCCH is located and the slot in which the PDSCH is located scheduled using the PDCCH. K2 is the slot offset between the slot in which the PDCCH is located and the slot in which the PUSCH is located, scheduled using the PDCCH. The aperiodic CSI-RS start offset is the slot offset between the slot in which the PDCCH is located and the slot in which the aperiodic CSI-RS started using the PDCCH is located. The aperiodic SRS start offset is the slot offset between the slot in which the PDCCH is located and the slot in which the aperiodic SRS started using the PDCCH is located.

[0010] The first scheduling mode is different from the second scheduling mode. The first scheduling mode is same-slot scheduling, and the second scheduling mode is inter-slot scheduling. The first scheduling mode is inter-slot scheduling and the second scheduling mode is same-slot scheduling. Alternatively, both the first scheduling mode and the second scheduling mode are inter-slot scheduling, but the slot offset in the first scheduling mode between the slot occupied by the PDCCH and the slot occupied by the data channel scheduled using the PDCCH is different from the slot offset in the first scheduling mode between the slot occupied by the PDCCH and the slot occupied by the data channel scheduled using the PDCCH. When scheduling the same slot, in order to ensure the reliability of the transmission of the data channel and/or the reference signal, the terminal needs to always allow the terminal's RF module to buffer the data channel and/or the reference signaling. However, when scheduling between slots, the terminal may temporarily turn off the terminal's RF module to save power.

[0011] In the method, according to the first aspect, the terminal may take an indication of the switch that is sent by the network device and which is used to indicate the shift of the terminal planning mode, and determine the time of application of the switched planning mode after receiving the shift, so that the terminal plans the data channel and/or launches A support signal using the planning mode, when the time of application of the switched planning mode comes.

Description of Embodiments

[00133] In order to facilitate understanding of the method provided in the embodiments of the present application, some terms in the embodiments of the present application are explained before the embodiments of the present application are described.

[00134] Physical downlink control channel (PDCCH): The physical downlink control channel is mainly used to carry downlink control information (DCI). The DCI may include general control information (eg, system information) and user-specific information (eg, downlink resource allocation indication, uplink scheduling, random access response, and uplink power control parameter). The PDCCH may be used to schedule a data channel using the DCI carried by the PDCCH. For example, DCI may be used to indicate a transmission parameter (eg, data channel time domain resource location) of the data channel. Before transmitting the data channel, the network device may send a PDCCH to the terminal. After receiving the PDCCH, the terminal may first demodulate the DCI on the PDCCH and then transmit the data channel at the time domain resource location indicated by the DCI.

[00135] Data channel: Data channel can be used to transfer data. In the 3GPP protocol, data channels are classified into a physical uplink shared channel (PUSCH) (or referred to as an uplink data channel) and a physical downlink data channel (PDSCH) (or referred to as a downlink data) based on various data carried in the data channels. PUSCH is used to carry data (or called uplink data) sent from a terminal to a network device. The PDSCH is used to carry data (or called downlink data) sent from a network device to a terminal.

[00136] In addition, the PDCCH may further indicate the location of the time domain resource of the channel state information reference signal (CSI-RS) using the DCI carried by the PDCCH to trigger the sending of the aperiodic (non-periodic) CSI-RS; The PDCCH may indicate the location of a sounding reference signal (SR) time domain resource using the DCI carried by the PDCCH to trigger the sending of an aperiodic SRS; and/or the like. For example, the PDCCH is used to trigger the sending of the CSI-RS. The network device may send the PDCCH to the terminal, and the DCI carried by the PDCCH is used to indicate the location of the CSI-RS time domain resource. After receiving the PDCCH, the terminal may demodulate the DCI on the PDCCH and receive, at the time domain resource location indicated by the DCI, the CSI-RS sent by the network device.

[00137] CSI-RS: The CSI-RS is used by the terminal to measure the channel state between the terminal and the network device, and the CSI-RS may include one or more channel state measurement resources. For example, the network device may send to the terminal a DCI used to indicate the location of the CSI-RS and CSI-RS time domain resource. The terminal receives the CSI-RS at the time domain resource location indicated by the DCI, measures the channel state measurement resource included in the CSI-RS, and reports channel state information (CSI) to the network device based on the measurement result.

[00138] SRS: SRS is used by a network device to measure channel information between a network device and a terminal. For example, the network device may send to the terminal a DCI used to indicate the location of the time domain resource for the SRS. The terminal receives the DCI and sends, at the time domain resource location indicated by the DCI, the SRS to the network device via some or all of the terminal's antennas. The network device receives the SRS and measures the channel information between the network device and the terminal based on the received SRS.

[00139] Bandwidth part (BWP): Part of the bandwidth is used for signal transmission. In the 3GPP standard, the bandwidth part can be classified into two types depending on the direction of the signal transmitted over the BWP: the uplink bandwidth part (UP BWP) and the downlink bandwidth part (DL BWP). ). The UP BWP may be used to transmit the signal sent from the terminal to the network device, that is, the terminal may send the uplink signal on the UL BWP. The downlink BWP may be used to transmit the signal sent from the network device to the terminal, and the terminal may receive the downlink signal over the DL BWP.

, где

- нумерология BWP. Большая нумерология BWP соответствует большему разнесению поднесущих BWP и меньшей длине символа. Например, когда разнесение поднесущих BWP составляет 15 кГц, длина слота, соответствующая BWP, составляет 1 мс. Когда разнесение поднесущих BWP составляет 30 кГц, длина слота, соответствующая BWP, составляет 0,5 мс.[00140] Various BWP parameters may be configured for different BWPs, and the BWP parameter may include the numerology (system parameter or parameter) of the BWP. The numerology corresponds to parameters such as BWP subcarrier spacing, BWP slot length, and BWP cyclic prefix (CP) length. The subcarrier spacing BWP is

, Where

- Numerology BWP. Larger BWP numerology corresponds to larger BWP subcarrier spacing and shorter symbol length. For example, when the BWP subcarrier spacing is 15 kHz, the slot length corresponding to the BWP is 1 ms. When the BWP subcarrier spacing is 30 kHz, the slot length corresponding to the BWP is 0.5 ms.

[00141] For example, the following table a is a BWP parameter table. As shown in Table a, the numerology may include five values from 0 to 4, and the subcarrier spacings corresponding to the five values are 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz, respectively.

Table a

numerology Subcarrier spacing (kHz) 0 15 1 thirty 2 60 3 120 4 240

[00142] In the 3GPP standard, when a terminal operates in one cell, there is only one active UL BWP and one active DL BWP. In other words, the terminal operates in only one active UL BWP and one active DL BWP at a time. The active BWP can be changed, i.e. the BWP can be switched at any time. For example, a network device configures two DL BWPs: DL BWP 1 and DL BWP 2 for the terminal, and DL BWP 1 is the active DL BWP. In this case, the network device may send a BWP switch indication via the PDCCH to instruct the terminal to switch from DL BWP 1 to DL BWP 2. Similarly, the network device may also indicate, using the PDCCH, the terminal to switch to the active UL BWP. The numerology of the BWP used before the switch may be different from the numerology of the BWP used after the switch.

[00143] One PDCCH may occupy one or more symbols in one slot (slot). The slot occupied by the PDCCH, the starting position of the symbols occupied by the PDCCH in the slot, and the number of symbols occupied by the PDCCH in the slot are not limited in embodiments of the present application. Optionally, when the PDCCH is used for data channel scheduling, the network device pre-configures a scheduling information monitoring occasion for the terminal. The terminal starts monitoring the PDCCH when a scheduling information monitoring event configured by the network device occurs. A scheduling information monitoring event may be periodically configured for the terminal such that the terminal periodically monitors the PDCCH.

[00144] The slot occupied by the PDCCH may be the same or different from the slot occupied by the data channel scheduled using the PDCCH and/or the slot occupied by the reference signal started using the PDCCH. In the 3GPP protocol, the terminal scheduling modes are divided into: single slot scheduling and cross-slot scheduling, scheduling based on the slot occupied by the PDCCH and the slot occupied by the data channel scheduled using the PDCCH. and/or the slot occupied by the reference signal started using the PDCCH. The scheduling of the same slot may indicate that the PDCCH and the data channel scheduled using the PDCCH and/or the reference signal started using the PDCCH are located in the same slot. Inter-slot scheduling may indicate that the PDCCH and the data channel scheduled using the PDCCH and/or the reference signal started using the PDCCH are located in different slots. For example,

when the PDCCH is used for PDSCH scheduling, the PDCCH and the PDSCH scheduled using the PDCCH can be located in the same slot, the same slot scheduling takes place; or can be located in different slots, that is, planning between slots takes place. In 3GPP, K0 is used to indicate whether the PDCCH and PDSCH scheduled using the PDCCH are in the same slot scheduling or inter-slot scheduling. K0 is the slot offset between the slot in which the PDCCH is located and the slot in which the PDSCH is located scheduled using the PDCCH. K0 has a value set, and the value set is configured by the network device for the terminal. For example, the set of values could be {0, 1, 2, ....}. If K0=0, this indicates that the PDCCH and PDSCH are in the same slot, i.e. "same slot scheduling" is taking place. If K0>0, this indicates that the PDCCH and PDSCH are not in the same slot, i.e. "inter-slot scheduling" is taking place. The network device may directly indicate K0 to the terminal, or the network device configures a time domain resource allocation (TDRA) table for the terminal. The TDRA table includes an index (index) and K0 corresponding to the index. The network device may indicate the index to the terminal to indirectly indicate K0 to the terminal.

[00145] For example, the following Table 1 is a schematic diagram of a TDRA table configured by a network device for a terminal when the PDCCH is used for PDSCH scheduling. The TDRA table includes a correspondence between the index and K0. As shown in Table 1, when the index is 0, K0 is 0; when the index is 1, K0 is 1; and when the index is 2, K0 is 1. When the network device schedules the PDSCH for the terminal with the PDCCH, the network device may configure the TDRA table shown in Table 1 for the terminal. Subsequently, if the network device indicates index 1 to the terminal, the terminal may search Table 1 using index 1 as an index to determine that K0 corresponding to index 1 is 1. Therefore, the PDCCH and PDSCH are in different slots, that is, there is scheduling between slots.

Table 1

Index (index) K0 0 0 1 1 2 1

[00146] When the PDCCH is used for PUSCH scheduling, the PDCCH and the PUSCH scheduled using the PDCCH may be located in the same slot, i.e. the same slot is scheduled, or may be located in different slots, i.e. There is planning between slots. In 3GPP, K2 is used to indicate whether the PDCCH and PUSCH scheduled using the PDCCH are in the same slot scheduling or inter-slot scheduling. K2 is the slot offset between the slot in which the PDCCH is located and the slot in which the PUSCH is located, scheduled using the PDCCH. K2 has a value set, and the value set is configured by the network device for the terminal. For example, a set of values can be {0, 1, 2, ....}. If K2=0, this indicates that the PDCCH and PUSCH are in the same slot, i.e. "same slot scheduling" is taking place. If K2>0, this indicates that the PDCCH and PUSCH are not in the same slot, i.e. "inter-slot scheduling" is taking place. The network device may directly indicate K2 to the terminal, or the network device configures the TDRA table for the terminal. The TDRA table includes the index (Index) and K2, which corresponds to the index. The network device may indicate the index to the terminal to indirectly indicate the terminal K2.

[00147] For example, the following Table 2 is a schematic diagram of a TDRA table configured by a network device for a terminal when the PDCCH is used for PUSCH scheduling. The TDRA table includes the correspondence between the index and K2. As shown in Table 2, when the index is 0, K2 is 0. When the index is 1, K2 is 2. When the network device schedules a PUSCH for the terminal with the PDCCH, the network device may configure the TDRA table shown in Table 2 for the terminal. Subsequently , if the network device indicates index 1 to the terminal, the terminal may search Table 2 using index 1 as an index to determine that the K2 corresponding to index 1 is 2. Therefore, the PDCCH and PDSCH are in different slots and have an offset in Two slots, that is, there is planning between the slots.

[00148] It should be noted that Table 1 and Table 2 are merely exemplary tables. In addition to the content shown in Table 1 and Table 2, Table 1 and Table 2 may further include other content, for example, may further include a sarting and length indication value, a mapping type type) , and the like. In this application, it is expressly not limited.

[00149] When the PDCCH is used to start the CSI-RS, the PDCCH and the CSI-RS started using the PDCCH may be located in the same slot, i.e. the same slot is being scheduled, or may be located in different slots, that is, there is scheduling between slots. In 3GPP, the aperiodic CSI-RS triggering offset is used to indicate whether the PDCCH and CSI-RS scheduled using the PDCCH are for same-slot scheduling or inter-slot scheduling. The start offset of the aperiodic CSI-RS is the slot offset between the slot in which the PDCCH is located and the slot in which the CSI-RS started using the PDCCH is located. The aperiodic CSI-RS trigger offset value may be included in the value set {0, 1, 2 ....}. The value set may be configured by the network device for the terminal. If the aperiodic CSI-RS start offset is 0, this indicates that the PDCCH and the CSI-RS started using the PDCCH are in the same slot, i.e. "same slot scheduling" occurs. If the aperiodic CSI-RS start offset is greater than 0, this indicates that the PDCCH and the CSI-RS started using the PDCCH are in different slots, i.e. "inter-slot scheduling" is taking place. The network device may directly indicate the start offset of the aperiodic CSI-RS to the terminal, or the network device may indicate the start offset of the aperiodic CSI-RS to the terminal in another way. It's not limited.

[00150] When the PDCCH is used to start the SRS, the PDCCH and the SRS started using the PDCCH may be located in the same slot, i.e. the same slot is scheduled, or may be located in different slots, i.e. inter-slot scheduling takes place. In 3GPP, the aperiodic SRS triggering offset is used to indicate whether the PDCCH and SRS scheduled using the PDCCH are in the same slot scheduling or inter-slot scheduling. The aperiodic SRS start offset is the slot offset between the slot in which the PDCCH is located and the slot in which the SRS started using the PDCCH is located. The aperiodic SRS trigger offset value may be included in the value set {0, 1, 2 ....}. The value set may be configured by the network device for the terminal. If the aperiodic SRS start offset is 0, it indicates that the PDCCH and the SRS started using the PDCCH are in the same slot, i.e. "same slot scheduling" is taking place. If the aperiodic SRS start offset is greater than 0, this indicates that the PDCCH and the SRS started using the PDCCH are in different slots, i.e. "inter-slot scheduling" is taking place. The network device may directly indicate the start offset of the aperiodic SRS to the terminal, or the network device may indicate the start offset of the aperiodic SRS to the terminal in another way.

[00151] For example, the PDCCH occupies slot 0 and the PDCCH is used for scheduling the PDSCH and PUSCH. As shown in FIG. 1, the location of the slot occupied by the PDSCH is changed to K0, and the location of the slot occupied by the PUSCH is changed to K2. For example, when the PDCCH is used for scheduling PDSCH 0, K0=0, and this indicates that the slot offset between the slot occupied by the PDCCH and the slot occupied by the PDSCH 0 scheduled using the PDCCH is 0. Therefore, PDSCH 0 is also at 0 th slot, i.e. slot 0 in FIG. 1. When the PDCCH is used for scheduling PDSCH 1, K0=1, and this indicates that the slot offset between the slot occupied by the PDCCH and the slot occupied by the PDSCH 1 scheduled using the PDCCH is 1. Therefore, the PDSCH 1 is located at (0 +1=1)th slot, i.e., slot 1. When the PDCCH is used for scheduling the PDSCH 2, K0=1, and this indicates that the slot offset between the slot occupied by the PDCCH and the slot occupied by the PDSCH 2 scheduled using the PDCCH , is equal to 1. Therefore, PDSCH 1 is located in the (0+1=1)th slot, that is, slot 1. When the PDCCH is used for scheduling PUSCH 0, K2=2, and this indicates that the slot offset between the slot occupied by the PDCCH , and the slot occupied by PUSCH 0 scheduled using the PDCCH is 2. Therefore, PUSCH 0 is located in the (0+2=2)th slot, namely slot 2. When the PDCCH is used for scheduling PUSCH 1, K2=2 , and it indicates that the slot offset between the slot occupied by the PDCCH and the slot occupied by the PUSCH 1 scheduled using the PDCCH is p is equal to 2. Therefore, PUSCH 0 is located in the (0+2=2)th slot, namely slot 2.

[00152] Currently, to reduce the power consumption of the terminal, optimization can be performed in two aspects. 1. When a service is transmitted (in other words, data must be transmitted), the efficiency of data transmission is improved. 2. When no service is being transmitted (in other words, no data is being transmitted), the power consumption of the terminal is reduced. Regarding point 2, the report of the international telecommunication union-radiocommunications sector (ITU-R) mentions that the power consumption of the terminal can be reduced by increasing the proportion in which the terminal is in the sleep state.

[00153] For example, as shown in FIG. 2, the terminal receives the PDCCH in the time period t1. As shown on the left side of FIG. 2, if the terminal does not know whether the same slot scheduling exists in the current slot (as long as the TDRA table configured by the base station includes K0=0, the same slot scheduling may exist) to avoid data loss and/ or signal loss, after receiving the PDCCH, the terminal needs to buffer the data and/or signal when decoding the PDCCH. At the time t2 shown on the left in FIG. 2, the terminal needs to allow the radio frequency module of the terminal to buffer data and/or signal all the time. As shown on the right side of FIG. 2 if the terminal can know in advance that inter-slot scheduling is performed between the PDCCH and the data channel and there is no data channel scheduled using the PDCCH and/or a reference signal started using the PDCCH in the current slot. In a process in which the terminal decodes the PDCCH after receiving the PDCCH, the terminal may turn off the RF module of the terminal and not buffer any data and/or signal to save power. As shown on the right side of FIG. 2, the shadow part corresponding to the time period t2 is the power saved for the terminal.

[00154] As described above, when there is no data service for the terminal, the terminal should be in the inter-slot scheduling state to reduce power consumption (the precondition is that all K0>0). When a data service occurs for a terminal, the terminal should be in the "Same slot scheduling" state to ensure fast data transmission and reduce delay. To enable the terminal's scheduling mode to quickly match the terminal's current service type, dynamic signaling can be used to indicate a scheduling mode switch, eg, to indicate a "valid" subset in the TDRA table. For example, there are three rows in a table. In the first line K0=0, and in the last two lines K0>0. Dynamic signaling can be used to indicate that only the last two lines are valid. Alternatively, the network device configures a plurality of TDRA tables (eg, configures a plurality of TDRA tables shown in Table 1) to dynamically indicate a "valid" table. For example, two TDRA tables are configured. In the first table TDRA K0=0. In the second TDRA table, all K0≥2. Alternatively, the network device dynamically specifies the minimum value of K0. For example, the network device dynamically indicates that the minimum value of K0 is 3. However, this solution simply briefly describes how to specify the scheduling mode, but does not specify in detail when the scheduling mode is applied. If the scheduling mode application time is not explicitly specified, signaling blur occurs between the network device and the terminal. For example, in the above method in which two TDRA tables are configured to dynamically indicate which one is valid, the network device and the terminal may consider at a particular time that different tables are valid. To solve this problem, embodiments of the present application provide a scheduling switching mode to refine the application time for scheduling mode switching.

It's not limited. Next, the communication system shown in FIG. 3 as an example to describe the method provided in the embodiments of the present application.

Upon receiving the switch indication, the terminal may determine when to apply the second scheduling mode and schedule the data channel and/or start the reference signal using the second scheduling mode when it is time to apply the second scheduling mode. Specifically, when the second scheduling mode is inter-slot scheduling, the terminal turns off the radio frequency module of the terminal to save power.

It's not limited. For example, the switching indication in the following embodiment can also be described as a power saving signal. It's not limited.

[00177] The following describes with reference to the communication system shown in FIG. 3, the scheduling switching method provided in the embodiments of the present application.

[00178] FIG. 5 - block diagram of the method of switching planning according to the option of implementing this application. As shown in FIG. 5, the method may include step 501 and step 502.

[00179] Step 501: The network device sends a switch indication to the terminal.

[00180] The network device may be the network device of FIG. 3, and the terminal may be any terminal in the system shown in FIG. 3.

[00181] The switch indication may be used to direct the terminal to switch from the first scheduling mode to the second scheduling mode. The first planning mode is different from the second planning mode. The first scheduling mode may be same-slot scheduling and the second scheduling mode may be inter-slot scheduling. Alternatively, the first scheduling mode is inter-slot scheduling and the second scheduling mode is same-slot scheduling. Alternatively, both the first scheduling mode and the second scheduling mode are inter-slot scheduling, but the slot offset in the first scheduling mode between the slot occupied by the PDCCH and the slot occupied by the data channel scheduled using the PDCCH is different from the slot offset in the first scheduling mode between the slot occupied by the PDCCH and the slot occupied by the data channel scheduled using the PDCCH. For example, K0 is 1 in the first scheduling mode and K0 is 2 in the second scheduling mode. In this application, this is definitely not limited. For descriptions relating to same-slot scheduling and inter-slot scheduling, refer to the above descriptions. Details are not again given.

[00182] In an exemplary implementation, the switch indication may include a pointer used to explain the second scheduling mode. The pointer can be a binary bit number. For example, when the switch indication includes binary bit 0, it indicates that the terminal's scheduling mode is the same slot scheduling. When the switch indication includes binary bit 1, it indicates that the terminal's scheduling mode is inter-slot scheduling.

[00183] In another possible implementation, the switch indication may include a parameter corresponding to the second scheduling mode. For example, the switch indication may include any one or more of the following: minimum value K0, minimum value K2, minimum aperiodic CSI-RS trigger offset value, and minimum aperiodic SRS trigger offset value. The terminal may determine, based on the parameter included in the switch indication, the scheduling mode to which to switch. For example, if the switch indication includes the minimum value of K0, and the minimum value of K0 is greater than 0, the terminal decides to switch to inter-slot scheduling. If the switch indication includes the minimum value K0, and the minimum value K0 is 0, it is determined that both same-slot scheduling and inter-slot scheduling can exist. If the switching indication includes K0 and K0 is 0, the terminal decides to switch to the same slot scheduling.

[00184] In yet another possible implementation, the switch indication may include an index (index), and the index may be used to indicate the second scheduling mode. For example, the index (index) may correspond to a minimum K0 value, a minimum K2 value, a minimum aperiodic CSI-RS trigger offset value, or a minimum aperiodic SRS trigger offset value. The terminal may determine the minimum value of K0, the minimum value of K2, the minimum value of the aperiodic CSI-RS trigger offset, or the minimum value of the aperiodic SRS trigger offset using the index, so that the terminal determines the terminal's scheduling mode based on the minimum value of K0, the minimum value of K2, the minimum offset value aperiodic CSI-RS trigger or minimum aperiodic SRS trigger offset.

[00185] For example, the network device may send a switch indication to the terminal via a communication channel between the network device and the terminal. In particular, the switch indication may be sent to the terminal via the PDCCH. For example, the switch indication may be sent to the terminal using a field in the DCI transmitted over the PDCCH, or the switch indication may be sent to the terminal using other signaling. For example, the switch indication may be sent to the terminal using a media access control element (MAC CE) carried on the PDSCH. In this application, it is expressly not limited.

[00186] It should be noted that the name of the switching indication is not limited in this embodiment of the present application. Alternatively, the switch indication may be referred to as another message. For example, the switch indication may alternatively be referred to as a power save signal. In this application, it is expressly not limited.

[00187] Step 502: The terminal receives a switch indication and determines when to apply the second scheduling mode.

[00188] For example, when a switch indication is sent to a terminal using a DCI sent over a PDCCH, the terminal may receive a PDCCH sent by a network device and receive a switch indication from a DCI included in the PDCCH. When a switch indication is sent to the terminal using the MAC CE transmitted on the PDSCH, the terminal may receive the PDSCH sent by the network device and receive the switch indication from the MAC CE included in the PDSCH.

[00189] The time of application of the second scheduling mode may be the time at which the terminal can schedule the data channel (eg, PDSCH or PUSCH) and/or start the reference signal (eg, CSI-RS or SRS) by using the second scheduling mode, or the time in which starts the second scheduling mode. When it is time to apply the second scheduling mode or after it is time to apply the second scheduling mode and before the next switch indication occurs, the terminal may configure a function module (eg, an RF module or a processing module configured to demodulate the PDCCH) of the terminal and schedule a channel data and/or trigger the reference signal using the second scheduling mode. For example, when the second scheduling mode is inter-slot scheduling, the terminal may turn off the radio frequency module of the terminal after the second scheduling mode is applied (or during the second scheduling mode is applied) to save power for the terminal.

[00190] In this embodiment of the present application, in order to ensure the reliability of sending the switch indication, the reliability of the data channel transmitted between the terminal and the network device, and the like, the application time of the second scheduling mode may be determined based on one or more factors such as such as whether the terminal correctly receives the PDCCH, whether the terminal correctly receives the data channel scheduled using the PDCCH, and the terminal's ability to process the PDCCH. Specifically, for the process of determining when to apply the second scheduling mode, refer to the following method 1 to method 7.

[00191] Based on the method shown in FIG. 5, after receiving the switch indication, the terminal can refine the application time of the scheduling mode used after the switch, so that the terminal schedules the data channel and/or starts the reference signal using the second scheduling mode when the second scheduling mode is applied. Specifically, when the second scheduling mode is inter-slot scheduling, if the terminal expects the terminal to be in a power save state, the terminal may turn off the radio frequency module of the terminal in a period of time (for example, a period of time after the terminal receives the PDCCH for scheduling data, and before after the terminal finishes PDCCH demodulation) after the second scheduling mode application time to enter the power saving state.

[00192] Several possible times for applying the second scheduling mode are described below with reference to the following methods 1 to 6:

[00193] Method 1: A switch indication is included in the PDCCH. The PDCCH may not be used for data channel scheduling and/or reference signal triggering, or may be used for data channel scheduling and/or reference signal triggering. In this application, it is expressly not limited.

[00194] That the switch indication is included in the PDCCH can also be described as that the switch indication is carried on the PDCCH, the switch indication is sent to the terminal via the PDCCH, the switch indication is included in the DCI in the PDCCH and is a field in the DCI, the switch indication is sent on terminal using the DCI on the PDCCH, the switch indication is the DCI on the PDCCH or the like. In this application, it is expressly not limited.

[00195] In method 1, in order to ensure the reliability (or accuracy) of the switching indication included in the PDCCH, the PDCCH may accordingly have feedback information. Once the terminal receives the PDCCH, the terminal sends a reception status to the network device so that the network device knows whether the terminal correctly receives the PDCCH. If it is determined that the terminal does not correctly receive the PDCCH, the network device resends the PDCCH including the switch indication.

[00196] Feedback information corresponding to a PDCCH including a switch indication may be referred to as PDCCH feedback information. PDCCH feedback information may be included in PUCCH or PUSCH. The PDCCH feedback information may occupy one or more symbols in one slot, and one symbol may occupy tens of microseconds (µs). The PDCCH feedback information may be used to indicate whether the terminal correctly receives the PDCCH including the switch indication. The PDCCH feedback information may be an acknowledgment (acknowledge, ACK) or a negative acknowledgment (non-acknowledge, NACK). If the terminal correctly receives the PDCCH, the terminal sends an ACK to the network device. Otherwise, if the terminal incorrectly receives the PDCCH including the switch indication, the terminal sends a NACK to the network device, so that the network device retransmits the switch indication to ensure the reliability of the switch indication included in the PDCCH. For example, the terminal may check with a cyclic redundancy check (CRC) method whether the terminal correctly receives a PDCCH including a switch indication. Details are not described here.

[00197] In order to avoid the problem that the reliability of the switching indication included in the PDCCH is reduced due to the fact that the terminal cannot send the PDCCH feedback information to the network device, in the method 1, the second planning mode may be after the time of use how the PDCch feedback information is sent, which includes the indication of the switch

[00198] In particular, the application time of the second scheduling mode can be implemented as shown in the following (1.1), (1.2) or (1.3).

[00199] (1.1) The application time of the second scheduling mode is the next symbol (symbol) of the last symbol occupied by the PDCCH feedback information.

[00200] The next symbol of the last symbol occupied by the PDCCH feedback information may be a symbol adjacent to the last symbol occupied by the PDCCH feedback information, or may be any symbol after the last symbol occupied by the PDCCH feedback information. In this application, it is expressly not limited.

[00201] The symbol in this embodiment of the present application has a certain length, and the duration of one symbol may be tens of microseconds (μs). For example, a symbol may be 71 µs long. When the symbol length is tens of µs, that the application time of the second scheduling mode is the next symbol of the last symbol occupied by the PDCCH feedback information may include: The application time of the second scheduling mode is the start time of the next symbol of the last symbol occupied by the feedback information PDCCH, or any other next symbol time of the last symbol occupied by the PDCCH feedback information. For example, the application time of the second scheduling mode may be the Q-th µs of the next symbol of the last symbol occupied by the PDCCH feedback information, where Q is a positive integer.

[00202] For example, each slot includes 14 symbols. As shown in FIG. 6a, the terminal receives in the first symbol in slot 1 a PDCCH including the switch indication, and sends in the twelfth symbol in slot 1 PDCCH feedback information including the switch indication to the network device. As shown by the dotted line in FIG. 6a, the application time of the second scheduling mode may be the thirteenth symbol or the fourteenth symbol after the twelfth symbol in slot 1. For example, the application time of the second scheduling mode is the thirteenth symbol in slot 1, and the duration of each symbol is 71 μs. The application time of the second scheduling mode may be, in particular, the 1st μs of the thirteenth symbol, may be the 50th μs of the thirteenth symbol, or may be the 71st μs of the thirteenth symbol. In this application, it is expressly not limited.

[00203] (1.2) The application time of the second scheduling mode is the next slot of the slot occupied by the PDCCH feedback information.

[00204] The next slot of the slot occupied by the PDCCH feedback information may be a slot after the slot occupied by the PDCCH feedback information and adjacent to the slot occupied by the PDCCH feedback information, or may be any slot after the slot occupied by the PDCCH feedback information. In this application, it is expressly not limited.

[00205] A slot in this embodiment of the present application may include a plurality of symbols. For example, one slot may include 12 or 14 symbols. When one slot includes a plurality of symbols, that the application time of the second scheduling mode is the next slot of the slot occupied by the PDCCH feedback information may include: The application time of the second scheduling mode is the start symbol in the next slot of the slot occupied by the feedback information PDCCH communications; or is any other symbol in the next slot of the slot occupied by the PDCCH feedback information. For example, the application time of the second scheduling mode may be the Rth symbol in the next slot of the slot occupied by the PDCCH feedback information, where R is a positive integer. Alternatively, when one slot includes a plurality of symbols, and the duration of one symbol is tens of µs, that the application time of the second scheduling mode is the next slot of the slot occupied by the PDCCH feedback information may include: The application time of the second scheduling mode is the start time of the symbol (e.g. the start symbol or any other symbol such as the Rth symbol) in the next slot of the slot occupied by the PDCCH feedback information, or the second scheduling mode application time is any other time in the symbol in the next slot of the slot, occupied by PDCCH feedback information. For example, the application time of the second scheduling mode is the Q-th μs symbol, where Q is an integer.

[00206] For example, each slot includes 14 symbols. As shown in FIG. 6b, the terminal receives in the first symbol in slot 1 a PDCCH including the switch indication, and sends in slot 1 PDCCH feedback information including the switch indication to the network device. As shown by the dotted line in FIG. 6b, the application time of the second scheduling mode may be the next slot of slot 1, namely slot 2. For example, when a slot includes 14 symbols, the application time of the second scheduling mode may be the first symbol in slot 2, may be the tenth symbol in slot 2, or may be the fourteenth symbol in slot 2. Alternatively, when the length of each symbol is tens of µs, the second scheduling mode application time may be the 1st µs of the first symbol in slot 2, or may be the 10th µs of the first symbol in slot 2, or may be the 50th µs of the first character in slot 2.

[00207] (1.3) The application time of the second scheduling mode is the first scheduling information monitoring event after the time domain location occupied by the PDCCH feedback information.

[00208] A scheduling information monitoring occasion may be an event when the terminal monitors the PDCCH used for data channel scheduling. A scheduling information monitoring event may occupy one or more symbols in one slot. In this application, it is expressly not limited. The terminal may start monitoring the PDCCH used for data channel scheduling when a scheduling information monitoring event occurs. In an actual application, the network device may configure a plurality of scheduling information monitoring events for the terminal. There is one or more slots between two adjacent scheduling information monitoring events such that the terminal periodically monitors the PDCCH used for data channel scheduling.

[00209] In order to avoid the problem that the data channel cannot be correctly transmitted because the terminal cannot detect the PDCCH used for scheduling the data channel, the second scheduling mode takes effect when the first scheduling information monitoring event occurs after the location in time domain occupied by the PDCCH feedback information. When the first scheduling information monitoring event occupies a plurality of symbols, that the application time of the second scheduling mode is the first scheduling information monitoring event after the time domain location occupied by the PDCCH feedback information may include: The application time of the second scheduling mode is the start symbol of the first scheduling information monitoring event after the time domain location occupied by the PDCCH feedback information, or may be any other symbol of the first scheduling information monitoring event.

[00210] When the first scheduling information monitoring event occupies a plurality of symbols, and each symbol occupies tens of µs, that the application time of the second scheduling mode is the first scheduling information monitoring event after the time domain location occupied by the PDCCH feedback information may include : The application time of the second scheduling mode is the symbol start time (eg, the start symbol or any other symbol) of the first scheduling information monitoring event after the time domain location occupied by the PDCCH feedback information, or the application time of the second scheduling mode is any other symbol time (eg, a start symbol or any other symbol) of the first scheduling information monitoring event after the time domain location occupied by the PDCCH feedback information. In this application, it is expressly not limited.

[00211] It should be noted that in (1.3), the first scheduling information monitoring event after the time domain location occupied by the PDCCH feedback information may be the scheduling information monitoring event that occurs for the first time after the time domain location occupied by the PDCCH feedback information, or may be any other scheduling information monitoring event after the time domain location occupied by the PDCCH feedback information. For example, the first scheduling information monitoring event after the time domain location occupied by the PDCCH feedback information may be the Nth scheduling information monitoring event after the time domain location occupied by the PDCCH feedback information, where N is a positive integer. .

[00212] For example, each slot includes 14 symbols. As shown in FIG. 6c, the terminal receives, in the first symbol in slot 1, a PDCCH including the switch indication, and sends in slot 1 feedback information of the PDCCH including DCI to the network device. If the first scheduling information monitoring event after the time domain location occupied by the PDCCH feedback information including the DCI is in slot 3. As shown by the dotted line in FIG. 6c, the application time of the second scheduling mode may be slot 3. For example, each slot includes 14 symbols, and the application time of the second scheduling mode may be a start symbol in slot 3, for example, may be the first symbol in slot 3, may be the tenth symbol. in slot 3, or may be the fourteenth symbol in slot 3. Alternatively, for example, the duration of each symbol is tens of µs, and the second scheduling mode application time may be 1 µs of the first symbol in slot 3, may be 10 µs of the first symbol in slot 3, or may be the 50th µs of the first symbol in slot 3.

[00213] Method 2: A switch indication is included in the PDCCH. In addition to the switch indication, the PDCCH may further include scheduling information. The scheduling information is used to schedule a downlink data channel (eg, PDSCH) of the terminal.

[00214] That the switch indication is included in the PDCCH can also be described as that the switch indication is carried on the PDCCH, the switch indication is sent to the terminal via the PDCCH, the switch indication is included in the DCI on the PDCCH, and is a field in the DCI the switch indication is sent to the terminal using the DCI on the PDCCH, the switch indication is the DCI on the PDCCH or the like. In this application, it is expressly not limited.

[00215] According to method 2, in order to ensure the reliability of the downlink data channel scheduled using the PDCCH, the terminal needs to send the downlink data channel feedback information to the network device. For example, once the terminal receives the downlink data channel scheduled using the PDCCH, the terminal returns the receive status to the network device so that the network device knows whether the terminal correctly receives the downlink data channel scheduled using the PDCCH. If the network device learns that the terminal incorrectly receives the downlink data channel scheduled using the PDCCH, the network device resends the downlink data channel to the terminal to ensure transmission reliability of the downlink data channel.

[00216] The downlink data channel feedback information may be included in the PUCCH or PUSCH. The downlink data channel feedback information may occupy one or more symbols in one slot, and one symbol may take tens of microseconds (μs). The downlink data channel feedback information may be used to indicate whether the terminal correctly receives the downlink data channel scheduled using the PDCCH including the switch indication. The downlink data channel feedback information may be ACK or NACK. If the terminal correctly receives the downlink data channel, the terminal sends an ACK to the network device. Otherwise, if the terminal incorrectly receives the downlink data channel, the terminal sends a NACK to the network device, so that the network device retransmits the downlink data channel to ensure transmission reliability of the downlink data channel. Specifically, the terminal can determine, using conventional technology, whether the terminal correctly receives the downlink data channel scheduled using the PDCCH. Details are not described here.

[00217] In order to avoid the problem that the reliability of the downlink data channel is reduced due to the fact that the terminal cannot send feedback information of the downlink data channel to the network device, in method 2, the application time of the second scheduling mode may be after the feedback information of the downlink data channel scheduled using the PDCCH is sent.

[00218] In particular, the application time of the second scheduling mode can be implemented as shown in the following (2.1), (2.2) or (2.3).

[00219] (2.1) The application time of the second scheduling mode is the next symbol of the last symbol occupied by the downlink data channel feedback information.

[00220] The next symbol of the last symbol occupied by the downlink data channel feedback information may be a symbol adjacent to the last symbol occupied by the downlink data channel feedback information, or may be any symbol after the last symbol occupied by the feedback information Data channel of the descending line of communication. In this application, this is definitely not limited.

[00221] When the symbol length is tens of µs, that the application time of the second scheduling mode is the next symbol of the last symbol occupied by the downlink data channel feedback information may include: The application time of the second scheduling mode is the start time of the next symbol of the last symbol occupied by the downlink data channel feedback information, or another next symbol time of the last symbol occupied by the downlink data channel feedback information. For example, the application time of the second scheduling mode may be the Q-th µs of the next symbol of the last symbol occupied by the downlink data channel feedback information, where Q is a positive integer.

[00222] For example, each slot includes 14 symbols. As shown in FIG. 7a, the terminal detects, on the first symbol in slot 0, the PDCCH including the switch indication, the downlink data channel scheduled using the PDCCH is located in slot 0, and the downlink data channel feedback information is located in the twelfth symbol in slot 1. As shown by the dotted line in FIG. 7a, the application time of the second scheduling mode may be the next symbol after the twelfth symbol in slot 1, such as the thirteenth symbol or the fourteenth symbol in slot 1. For example, the application time of the second scheduling mode is the thirteenth symbol in slot 1, and the duration of each symbol is 71 μs. . The application time of the second scheduling mode may be, in particular, the start of the thirteenth symbol, for example, may be the 1st μs of the thirteenth symbol, may be the 50th μs of the thirteenth symbol, or may be the 71st μs of the thirteenth symbol. In this application, it is expressly not limited.

[00223] (2.2) The application time of the second scheduling mode is the next slot of the slot occupied by the downlink data channel feedback information.

[00224] The next slot of the slot occupied by the downlink data channel feedback information may be the next slot after the slot occupied by the downlink data channel feedback information and adjacent to the slot occupied by the downlink data channel feedback information, or may be any slot after the slot occupied by the downlink data channel feedback information. In this application, it is expressly not limited.

[00225] The slot in this embodiment of this application may include many characters, for example, may include 12 or 14 characters. Когда один слот включает в себя множество символов, то, что время применения второго режима планирования является следующим слотом слота, занятого информацией обратной связи канала данных нисходящей линии связи, может включать в себя: Время применения второго режима планирования является начальным символом в следующем слоте слота, occupied by the feedback information of the downlink data channel; Or it is any other symbol in the next slot of the slot occupied by the feedback from the data channel of the descending line of communication. For example, the time of application of the second planning mode can be a R -Mic symbol in the next slot of the slot, the feedback from the data channel of the descending communication line, where R is a positive integer. As an alternative, when a slot occupied by the information of the data channel of the descending communication line includes many characters, and the duration of each symbol is dozens of ISS, the fact that the time of application of the second planning mode is the next slot of the data of the data channel feedback information the descending line of communication may include: the time of application of the second planning mode is the initial moment of the symbol (for example, the initial symbol or any other symbol) in the next slot of the slot of the feedback from the data channel of the descending line of communication, or another moment of the symbol in the next slot of the slot of the slot occupied by the feedback information of the downlink data channel. For example, the time of application of the second planning regime is the Q -nichest symbol in the next slot of the slot occupied by the feedback from the data channel of the descending communication line, where Q is an integer.

[00226] For example, each slot includes 14 characters. As shown in FIG. 7b, the terminal detects on the first symbol in slot 0 the PDCCH including the switch indication, the downlink data channel scheduled using the PDCCH including the switch indication is located in slot 0, and the downlink data channel feedback information is On the twelfth symbol in the slot 1. as shown by a dotted line for FIG. 7b, the application time of the second scheduling mode may be the next slot of slot 1, for example, may be the start time of slot 2. Specifically, when the slot includes 14 symbols, the application time of the second scheduling mode may be the start symbol in slot 2, for example, may be the first symbol, may be the tenth symbol in slot 2, or may be the fourteenth symbol in slot 2. Alternatively, when the duration of each symbol is tens of µs, the second scheduling mode application time may be the start time of the first symbol in slot 2, for example, be the 1st µs of the first symbol in slot 2, may be the 10th µs of the first symbol in slot 2, or may be the 50th µs of the first symbol in slot 2.

[00227] (2.3) The second scheduling mode application time is the first scheduling information monitoring event after the time domain location occupied by the downlink data channel feedback information.

[00228] Descriptions related to the planning monitoring event are described in method 1, and details are not described again. It should be noted that in (2.3) the first event monitoring of planning information after the location in the temporary area occupied by the information of the data channel of the descending communication line may be an event to monitor planning information that appears for the first time after the location in the temporary field of the feedback information of the channel data of the descending communication line, or can be any other event monitoring of planning information after location in the temporary area occupied by the feedback from the data channel of the descending line of communication. For example, the first event monitoring of planning information after the location in the temporary area occupied by the feedback from the data channel of the descending line of communication may be the N-M Enterian for Monitoring Planning Information after the location in the temporary field, the feedback of the data channel in the descending line of communication, where n positive integer.

[00229] In order to avoid the problem that the data channel cannot be correctly transmitted because the terminal cannot detect the PDCCH used for scheduling the data channel, the second scheduling mode takes effect when the first scheduling information monitoring event occurs after the location in time domain occupied by the downlink data channel feedback information.

[00230] When the first scheduling information monitoring event occupies a plurality of symbols, that the application time of the second scheduling mode is the first scheduling information monitoring event after the time domain location occupied by the downlink data channel feedback information may include: Application time of the second scheduling mode is the start symbol of the first scheduling information monitoring event after the time domain location occupied by the downlink data channel feedback information, or may be any other symbol of the first scheduling information monitoring event after the time domain location is occupied by the downlink data channel feedback information communication lines.

[00231] When the first scheduling information monitoring event occupies a plurality of symbols, and each symbol occupies tens of µs, that the application time of the second scheduling mode is the first scheduling information monitoring event after the time domain location occupied by the downlink data channel feedback information, may include: The application time of the second scheduling mode is a symbol start time (eg, a start symbol or any other symbol) of the first scheduling information monitoring event after the time domain location occupied by the downlink data channel feedback information, or the application time of the second scheduling mode is any other symbol instant (eg, start symbol or any other symbol) of the first scheduling information monitoring event after the time domain location occupied by the downlink data link feedback information current communication lines. In this application, this is definitely not limited.

[00232] For example, as shown in FIG. 7c, the terminal detects, in the first symbol in slot 0, the PDCCH including the switch indication, the downlink data channel scheduled using the PDCCH including the switch indication is located in slot 0, and the downlink data channel feedback information connection is in the twelfth symbol in slot 1. If the first scheduling information monitoring event after the time domain location occupied by the downlink data channel feedback information is in slot 3. As shown by the dotted line in FIG. 7c, the application time of the second scheduling mode may be a start time or another time in slot 3. For example, each slot includes 14 symbols, and the application time of the second scheduling mode may be the first symbol in slot 3, may be the tenth symbol in slot 3, or may be the fourteenth symbol in slot 3. Alternatively, for example, the duration of each symbol is tens of µs, and the second scheduling mode application time may be 1 µs of the first symbol in slot 3, may be 10 µs of the first symbol in slot 3 , or it could be the 71st µs of the first character in slot 3.

[00233] Method 3: A switch indication is included in the PDCCH. In addition to the switch indication, the PDCCH may further include scheduling information. The scheduling information is used for scheduling an uplink data channel (eg, PUSCH).

[00234] That the switch indication is included in the PDCCH can also be described as that the switch indication is carried on the PDCCH, the switch indication is sent to the terminal via the PDCCH, the switch indication is included in the DCI on the PDCCH and is a field in the DCI, the switch indication is sent on terminal using the DCI on the PDCCH, the switch indication is the DCI on the PDCCH or the like. In this application, it is expressly not limited.

[00235] In method 3, in order to ensure the reliability of the uplink data channel scheduled using the PDCCH, the second scheduling mode comes into effect after the terminal receives the uplink data channel scheduled using the PDCCH.

[00236] In particular, the application time of the second scheduling mode can be implemented as shown in the following (3.1), (3.2) or (3.3).

[00237] (3.1) The application time of the second scheduling mode is the next symbol of the last symbol occupied by the uplink data channel.

[00238] The next symbol of the last symbol occupied by the uplink data channel may be a symbol adjacent to the last symbol occupied by the uplink data channel, or may be any symbol after the last symbol occupied by the uplink data channel. In this application, it is expressly not limited.

[00239] When the symbol length is tens of microseconds, that the application time of the second scheduling mode is the next symbol of the last symbol occupied by the uplink data channel may include: The application time of the second scheduling mode is the start time of the next symbol of the last symbol, occupied by the uplink data channel, or another next symbol time of the last symbol occupied by the feedback information of the downlink data channel. For example, the application time of the second scheduling mode may be the Q-th μs of the next symbol of the last symbol occupied by the downlink data channel feedback information, where Q is a positive integer.

[00240] For example, each slot includes 14 symbols. As shown in FIG. 8a, the terminal detects at the first symbol in slot 0 a PDCCH including the switch indication, and an uplink data channel scheduled using the PDCCH including the switch indication is located at the twelfth symbol in slot 0. As shown by the dotted line in FIG. . 8a, the application time of the second scheduling mode may be the next symbol after the twelfth symbol in slot 0, such as the thirteenth symbol or the fourteenth symbol in slot 0. For example, the application time of the second scheduling mode is the thirteenth symbol in slot 0, and the duration of each symbol is 71 μs. . The time of application of the second scheduling mode may be, in particular, the start of the thirteenth symbol in slot 0, for example, may be the 1st μs of the thirteenth symbol, may be the 50th μs of the thirteenth symbol, or may be the 71st μs of the thirteenth symbol. In this application, it is expressly not limited.

[00241] (3.2) The application time of the second scheduling mode is the next slot of the slot occupied by the uplink data channel.

[00242] The next slot of the slot occupied by the uplink data channel may be a slot after the slot occupied by the uplink data channel and adjacent to the slot occupied by the uplink data channel, or may be any slot after the slot occupied by the uplink data channel communication lines. In this application, it is expressly not limited.

[00243] A slot in this embodiment of the present application may include a plurality of symbols, such as 12 or 14 symbols. When one slot includes a plurality of symbols, that the application time of the second scheduling mode is the next slot of the slot occupied by the uplink data channel may include: The application time of the second scheduling mode is the start symbol in the next slot of the slot occupied by the channel uplink data, or any other symbol in the next slot of the slot occupied by the uplink data channel. For example, the application time of the second scheduling mode may be the Rth symbol in the next slot of the slot occupied by the uplink data channel, where R is a positive integer.

[00244] When the slot occupied by the uplink data channel includes a plurality of symbols, and the duration of each symbol is tens of µs, that the application time of the second scheduling mode is the next slot of the slot occupied by the uplink data channel include : The application time of the second scheduling mode is the symbol start time (eg start symbol or any other symbol) in the next slot of the slot occupied by the uplink data channel, or any other symbol time in the next slot of the slot occupied by the uplink data channel. For example, the application time of the second scheduling mode is the Q-th µs symbol in the next slot of the slot occupied by the uplink data channel, where Q is an integer.

[00245] For example, each slot includes 14 symbols. As shown in FIG. 8b, the terminal detects on the first symbol in slot 0 a PDCCH including the switch indication, and an uplink data channel scheduled using the PDCCH including the switch indication is located in the twelfth symbol in slot 0. As shown by the dotted line in FIG. . 8b, the application time of the second scheduling mode may be the next slot of slot 1, for example, may be the start time of slot 1. Specifically, when the slot includes 14 symbols, the application time of the second scheduling mode may be the start symbol in slot 1, for example, may be the first symbol in slot 1, may be the tenth symbol in slot 1, or may be the fourteenth symbol in slot 1. Alternatively, when the duration of each symbol is tens of microseconds, the second scheduling mode application time may be the start of the first symbol in slot 1 , for example, it could be the 1st µs of the first symbol in slot 1, it could be the 10th µs of the first symbol in slot 1, or it could be the 71st µs of the first symbol in slot 1.

[00246] (3.3) The second scheduling mode application time is the first scheduling information monitoring event after the time domain location occupied by the uplink data channel.

[00247] Descriptions relating to the scheduling information monitoring event are described in Method 1, and details are not described again. It should be noted that in (3.3), the first scheduling information monitoring event after the time domain location occupied by the uplink data channel may be the scheduling information monitoring event that occurs for the first time after the time domain location occupied by the uplink data channel, or may be any other scheduling information monitoring event after the time domain location occupied by the uplink data channel. For example, the first scheduling information monitoring event after the time domain location occupied by the uplink data channel may be the Nth scheduling information monitoring event after the time domain location occupied by the uplink data channel, where N is a positive integer.

[00248] To avoid the problem that the data channel cannot be correctly transmitted due to the fact that the terminal cannot detect the PDCCH used for scheduling the data channel, the second scheduling mode takes effect when the first scheduling information monitoring event occurs after the time domain location occupied by the uplink data channel.

[00249] When the first scheduling information monitoring event occupies a plurality of symbols, that the application time of the second scheduling mode is the first scheduling information monitoring event after the time domain location occupied by the uplink data channel may include: The application time of the second scheduling mode is the start symbol of the first scheduling information monitoring event after the time domain location occupied by the uplink data channel, or may be any other symbol of the first scheduling information monitoring event after the time domain location occupied by the uplink data channel. Alternatively, when the first scheduling information monitoring event occupies a plurality of symbols and each symbol occupies tens of µs, that the application time of the second scheduling mode is the first scheduling information monitoring event after the time domain location occupied by the uplink data channel may include into itself: The application time of the second scheduling mode is the symbol start time (for example, the start symbol or any other symbol) of the first scheduling information monitoring event after the time domain location occupied by the uplink data channel, or the application time of the second scheduling mode is any a different symbol moment (eg, start symbol or any other symbol) of the first scheduling information monitoring event after the time domain location occupied by the uplink data channel. In this application, it is expressly not limited.

[00250] For example, as shown in FIG. 8c, the terminal detects on the first symbol in slot 0 a PDCCH including the switch indication, an uplink data channel scheduled using the PDCCH including the switch indication is located in the twelfth symbol in slot 0, and the first scheduling information monitoring event after the time domain location occupied by the uplink data channel is located in slot 2. As shown by the dotted line in FIG. 8c, the application time of the second scheduling mode may be a start time or another time of slot 2. For example, each slot includes 14 symbols, and the application time of the second scheduling mode may be the first symbol in slot 2, may be the tenth symbol in slot 2, or may be the fourteenth symbol in slot 2. Alternatively, for example, the duration of each symbol is tens of µs, and the time to apply the second scheduling mode may be the 1st µs of the first symbol in slot 2, may be the 10th µs of the first symbol in slot 2, or it could be the 71st µs of the first character in slot 2.

[00251] It should be noted that in the above method 2 or method 3, the application time of the second scheduling mode is described using an example in which the PDCCH including the switch indication is used for data channel scheduling. It can be understood that when the PDCCH including the switch indication is further used to trigger the reference signal, for example, to trigger the CSI-RS and/or SRS, so as not to affect the triggering of the CSI-RS and/or SRS, the second scheduling mode should take effect after the launch of the CSI-RS and/or SRS. For example, the application time of the second scheduling mode may be the next symbol of the last symbol occupied by the reference signal started using the PDCCH, the application time of the second scheduling mode may be the next slot of the slot occupied by the reference signal started using the PDCCH, or the application time of the second scheduling mode may be be the first scheduling information monitoring event after the time domain location occupied by the reference signal started using the PDCCH.

[00252] Method 4: A switch indication is included in the PDCCH and the PDCCH is in the Nth slot. For example, the PDCCH may occupy one or more symbols in the Nth slot, where N is an integer. The PDCCH including the switch indication may be used for scheduling the data channel and/or the reference signal, or may not be used for scheduling the data channel and/or the reference signal. In this application, it is expressly not limited.

[00253] In Method 4, the timing of applying the second scheduling mode is related to the processing rate of the PDCCH by the terminal. The PDCCH processing rate of the terminal is related to one or more of the minimum value K0, the minimum value K2, the minimum aperiodic CSI-RS trigger offset value, and the minimum aperiodic SRS trigger offset value corresponding to the PDCCH. For example, the processing rate of the PDCCH by the terminal is related to the minimum value of K0 corresponding to the PDCCH. When the minimum value of K0 is relatively large, the processing rate of the PDCCH by the terminal is relatively low, and the application time of the second scheduling mode is relatively late. When the minimum value of K0 is relatively small, the PDCCH processing rate of the terminal is relatively high, and the application time of the second scheduling mode is relatively early.

[00254] In particular, the time of application of the second planning mode can be implemented as shown in the following (4.1) or (4.2).

[00255] (4.1) The application time of the second scheduling mode is the (N+M)-th slot.

[00256] N may be used to indicate the location of the slot occupied by the PDCCH. In particular, N may be an index corresponding to a slot occupied by the PDCCH. For example, if the slot occupied by the PDCCH is slot 0, N is 0.

[00257] For example, when each slot includes a plurality of symbols, that the application time of the second scheduling mode is the (N+M)th slot may include: The application time of the second scheduling mode is the start symbol in (N+M )-th slot, or any other character in the (N+M)-th slot, for example, may be the R-th character in the (N+M)-th slot, where R is an integer. Alternatively, when the length of each symbol is tens of µs, that second scheduling mode application time of (N+M)th slot may include: symbol or any other symbol) in the (N+M)-th slot, or any other symbol moment in the (N+M)-th slot, for example, may be the Q-th µs in the (N+M)-th slot, where Q is an integer.

[00258] (4.2) The application time of the second scheduling mode is not earlier than the first scheduling information monitoring event for the (N+M)th slot.

[00259] Descriptions related to the scheduling information monitoring event are described in Method 1, and details are not described again.

[00260] When the first scheduling information monitoring event occupies a plurality of symbols, that the application time of the second scheduling mode is not earlier than the first scheduling information monitoring event of the (N+M)th slot may include: The application time of the second scheduling mode is - not earlier than the start symbol of the first scheduling information monitoring event of the (N+M)-th slot, or not earlier than any other symbol of the first scheduling information monitoring event of the (N+M)-th slot. Alternatively, when the first scheduling information monitoring event occupies a plurality of symbols and each symbol occupies tens of µs, that the application time of the second scheduling mode is no earlier than the first scheduling information monitoring event of the (N+M)th slot may include itself: The application time of the second scheduling mode is not earlier than the symbol start time (eg, the start symbol or any other symbol) of the first scheduling information monitoring event of the (N+M)th slot, or the application time of the second scheduling mode is not earlier than any other symbol time (eg, the start symbol or any other symbol) of the first scheduling information monitoring event of the (N+M)th slot. In this application, it is expressly not limited.

[00261] M is determined based on the applicable minimum slot offset value (min value) when the terminal receives a switch indication, and the slot offset is the slot offset between the slot occupied by the PDCCH used for scheduling the data channel (and/or reference signal) and the slot occupied by the data channel (and/or reference signal) scheduled using the PDCCH used for data channel scheduling. For example, the minimum value may be a minimum K0 value, a minimum K2 value, a minimum aperiodic CSI-RS trigger offset value, or a minimum aperiodic SRS trigger offset value. The slot corresponding to M is not earlier than the slot corresponding to the minimum value. For example, the minimum value may be indicated to the terminal with reference to a TDRA table configured by the network device for the terminal. For example, the network device may configure a TDRA table for a terminal and indicate to the terminal a plurality of indexes in the TDRA table such that the terminal determines the minimum value from the plurality of values that are in the TDRA table that correspond to the plurality of indices. For example, the TDRA table configured by the network device for the terminal is shown in Table 1. The network device indicates to the terminal that the first three rows, index 0, index 1, and index 2 in the TDRA table are valid. Therefore, table 1 is queried to determine that the minimum value is 0.

[00262] In particular, the relationship between M and the minimum value can be described as shown in (4.2.1), (4.2.2) or (4.2.3).

[00263] (4.2.1) M is equal to the minimum value.

[00264] When the application time of the second scheduling mode is determined using the slot as the granularity, the application time of the second scheduling mode may be the (N+M)-th slot after the N-th slot. For example, if the slot occupied by the PDCCH including the switch indication is slot 0 and the minimum value is 2, the application time of the second scheduling mode is slot 2.

[00265] It should be noted that when each slot includes a plurality of symbols, and the application time of the second scheduling mode is determined using the symbol as the granularity, M may be equal to the product of the minimum value and (the number of symbols included in each slot). In this case, the application time of the second scheduling mode may be a symbol which is after the last symbol occupied by the PDCCH including the switch indication and whose offset from the last symbol occupied by the PDCCH including the switch indication is the product of the minimum value and (the number characters in each slot). For example, if the PDCCH including the switch indication occupies slot 0, the last symbol occupied by the PDCCH is the fifth symbol in slot 0, the minimum value is 2, and each slot includes 14 symbols, there is an offset of 28 symbols between the application time of the second scheduling mode and the fifth character in slot 0. Therefore, the application time of the second scheduling mode may be the tenth character in slot 2.

[00266] (4.2.2) M is equal to the sum of the minimum value and the first value.

[00267] The first value may be referred to as an additional application delay. The first value may be in one slot, and the first value may be one slot. Alternatively, the first value may be in character units. For example, the first value could be 14 characters, or 12 characters.

[00268] When the application time of the second scheduling mode is determined using the slot as the granularity, the first value is in slot unit, and the application time of the second scheduling mode may be the (N+minimum value+first value)-th slot after the N-th slot . For example, if the slot occupied by the PDCCH including the switch indication is slot 0 and the minimum value is 2, the application time of the second scheduling mode is slot 3.

[00269] It should be noted that when each slot includes many characters, and the time of application of the second planning mode is determined using the symbol as the degree of detail, the first value is expressed in the units of the symbol, and M may be equal to the sum of the first value and work the minimum value and (the number of characters included in each slot). In this case, the time of application of the second planning mode can be a symbol that is located after the last symbol occupied by PDCCH, which includes an indication of switching, and whose displacement from the last symbol occupied by PDCC, which includes an indication of switching, is the sum of the first value and work of the minimum meanings and (number of characters in each slot). For example, if the PDCCH, which includes the indication of the switch, takes the slot 0, the last symbol occupied by PDCCH, is the fifth symbol in the slot 0, the minimum value is 2, each slot includes 14 characters, and the first value is 12 characters, there is a displacement In 40 characters between the time of application of the second planning mode and the fifth symbol in the slot 0. Therefore, the time of application of the second planning mode can be the eighth symbol in the slot 3.

[00270] (4.2.3) The slot corresponding to M is not earlier than the slot corresponding to the minimum value, and the slot corresponding to M is not earlier than the slot corresponding to the second value. In particular, M may be the maximum value between the second value and the minimum value.

[00271] The second value can be called the minimum switching value, and the second value is associated with the possibility of demodulation of the PDCC terminal. The stronger ability of the demodulation of terminal means less second value, and the weaker ability of the demodulation of the terminal means greater second value. The second value is also associated with the spacing of the sub -summers, currently configured for the terminal. Smaller spacing of the transit means a larger slot length and a smaller second value. The larger spacing of the transit means a lower slot length and a greater second value.

[00272] The second value may be in slot units. For example, the second value can be one (slot) or another value. Alternatively, the first value may be in character units. For example, the first value could be 14 characters, or 12 characters.

[00273] When the time of application of the second planning mode is determined using the slot as the degree of detail, the second value is expressed in the unit of the slot, and the time of application of the second planning mode can be Max (the second value, the minimum value) -m slot after the nth slot. For example, if a slot engaged in PDCch, which includes a shift indication, is a slot 0, the minimum value is 2, and the second value is 1, the use time of the second planning mode is slot 2.

[00274] It should be noted that when each slot includes a plurality of symbols, and the application time of the second scheduling mode is determined using the symbol as the granularity, the second value is expressed in symbol units, and M may be equal to max(second value, product minimum value and (number of symbols included in each slot)). In this case, the application time of the second scheduling mode may be a symbol which is after the last symbol occupied by the PDCCH including the switch indication and whose offset from the last symbol occupied by the PDCCH including the switch indication is max(second value, product minimum value and (number of characters in each slot)). For example, if the PDCCH including the switch indication occupies slot 0, the last symbol occupied by the PDCCH is the fifth symbol in slot 0, the minimum value is 2, each slot includes 14 symbols, and the second value is 12 symbols, there is an offset 28 symbols between the application time of the second scheduling mode and the fifth symbol in slot 0. Therefore, the application time of the second scheduling mode may be the tenth symbol in slot 2.

[00275] For example, as shown in FIG. 9a, the terminal detects scheduling information in slot 0 and slot 3, and receives on the tenth symbol in slot 1 a PDCCH including a switch indication. When the terminal receives a PDCCH including a switch indication, the applicable minimum value of K0 is 0. Assuming the second value uses the slot as the granularity, the second value is 1 (number of symbols) and M=max(1, minimum value of K0) =1. Therefore, the application time of the second scheduling mode may be the (1+1)th slot, namely slot 2. Alternatively, the application time of the second scheduling mode takes effect no earlier than the first monitoring event of the scheduling information of slot 2. Alternatively, , assuming that M=minimum value K0+1=1, the application time of the second scheduling mode may be the (1+1)th slot, namely slot 2. Alternatively, the application time of the second scheduling mode takes effect no earlier than than the first monitoring event of slot 2 scheduling information. Assuming that the second value uses a character as the granularity, the application time of the second scheduling mode uses a character as the granularity, the second value is five characters, the first value is eight characters, and each slot includes 14 characters, M=max(5, 0)=5. The application time of the second scheduling mode may be the first symbol in slot 2. Alternatively, assuming M=8+the product of the minimum value K0 and the number of symbols included in each slot=8, the application time of the second scheduling mode may be the fourth symbol in slot 2.

[00276] In another example, as shown in FIG. 9b, the terminal detects scheduling information in slot 0, slot 2, and slot 4, and receives on the tenth symbol in slot 1 a PDCCH including a switch indication. When the terminal receives a PDCCH including a switch indication, the applicable minimum value of K0 is 2. Assuming the second value uses a slot as the granularity, the second value is 1 and M=max(1, minimum value of K0)=2. Therefore, the application time of the second scheduling mode may be the (1+2)th slot, namely slot 3. Alternatively, the application time of the second scheduling mode takes effect no earlier than the first monitoring event of the scheduling information of slot 3. Alternatively, , assuming that M=minimum value K0+1=3, the application time of the second scheduling mode may be the (1+2)th slot, namely slot 3. Alternatively, the application time of the second scheduling mode does not take effect until than the first scheduling information monitoring event in slot 3. Assuming the second value uses a character as the granularity, the application time of the second scheduling mode uses a character as the granularity, the second value is five characters, the first value is eight characters, and each slot includes includes 14 characters, M=max(5, 2×14)=28. The application time of the second scheduling mode may be the tenth symbol in slot 3. Alternatively, assuming M=8+the product of the minimum value K0 and the number of symbols included in each slot=28+8=36, the application time of the second scheduling mode may be the fourth character in slot 4.

[00277] It should be noted that in Method 4, when the PDCCH including the switch indication is not used for data channel and/or reference signal scheduling, the application time of the second scheduling mode is irrelevant to the time domain location occupied by the feedback information. The PDCCH or application time of the second scheduling mode is related to the location in the time domain occupied by the PDCCH feedback information. The application time of the second scheduling mode depends on the latest application time determined in (4.1) or (4.2) in Method 4 and the location in the time domain occupied by the PDCCH feedback information. The second scheduling time takes effect after the last time.

[00278] When the PDCCH, which includes a switching indication, is used to plan a data channel for a descending communication line, the time of application of the second planning mode is not related to the temporary field occupied by the feedback from the data channel planned using PDCCH. As an alternative, the time of application of the second planning regime is associated with the location in the temporary field occupied by the information of the data channel of the descending communication line planned using PDCCH. The time of application of the second planning regime depends on the latest time of application determined in (4.1) or (4.2) in method 4, and the location in the temporary field, which is engaged in the feedback from the data channel for the downward communication line, planned using PDCCH. The second scheduling time takes effect after the last time.

[00279] When the PDCCH including the switch indication is used for scheduling an uplink data channel, the application time of the second scheduling mode is irrelevant to the time domain location occupied by the uplink data channel scheduled using the PDCCH. Alternatively, the application time of the second scheduling mode is related to the time domain location occupied by the uplink data channel scheduled using the PDCCH. The application time of the second scheduling mode depends on the latest application time determined in (4.1) or (4.2) in Method 4 and the time domain location occupied by the uplink data channel scheduled using the PDCCH. The second scheduling time takes effect after the last time.

[00280] Method 5: A switch indication is included in a media access control element (MAC CE) and a MAC CE is included in the PDSCH.

[00281] That the MAC CE is included on the PDSCH can also be described as that the MAC CE is carried on the PDSCH, or the MAC CE is sent to the terminal on the PDSCH, or the like. In this application, it is expressly not limited.

[00282] In method 5, in order to ensure that the terminal receives the MAC CE and further learns, based on the received MAC CE, the scheduling mode indicated by the switch indication, the second scheduling mode should take effect after the slot occupied by the PDSCH feedback information. For example, the application time of the second scheduling mode is later than the slot occupied by the PDSCH feedback information, and the offset between the application time of the second scheduling mode and the slot occupied by the PDSCH feedback information is the first duration. Alternatively, the application time of the second scheduling mode occurs after the first duration, ie after the slot occupied by the PDSCH feedback information.

[00283] The PDSCH feedback information is used to indicate whether the terminal correctly receives the PDSCH. The first duration is related to the time when the physical layer of the terminal receives the PDSCH and transmits the MAC CE included in the PDSCH to the MAC layer of the terminal. For example, the first duration may be greater than or equal to the time at which the physical layer of the terminal receives the PDSCH and transmits the MAC CE included in the PDSCH to the MAC layer of the terminal. For example, the first duration may be 3 ms.

[00284] Method 6: the time of application of the second planning mode is time after all data channels are planned using planning information, which is no later than the indication of switching, transmitted to guarantee the normal transmission of data channels.

[00285] In method 6, a switch indication may be included in the PDCCH. The PDCCH may be used for scheduling the data channel and/or the reference signal, or may not be used for scheduling the data channel and/or the reference signal. In this application, it is expressly not limited. The data channel may be a downlink data channel or an uplink data channel, and the reference signal may be CSI-RS or SRS.

[00286] Specifically, for example, the scheduling information which is not later than the switch indication is the first scheduling information, and the application time of the second scheduling mode may be realized as described in (6.1), (6.2) or (6.3).

[00287] (6.1) The application time of the second scheduling mode is the next symbol of the last symbol occupied by the data channel scheduled using the first scheduling information.

[00288] The next symbol of the last symbol occupied by the data channel scheduled using the first scheduling information may be a symbol adjacent to the last symbol occupied by the data channel scheduled using the first scheduling information, or may be any symbol after the last symbol occupied by the channel data scheduled using the first scheduling information. In this application, it is expressly not limited.

[00289] The symbol in this embodiment of the present application has a certain length, and the duration of one symbol may be tens of microseconds. For example, a symbol may be 71 µs long. When the symbol length is tens of µs, that the application time of the second scheduling mode is the next symbol of the last symbol occupied by the data channel scheduled using the first scheduling information may include: The application time of the second scheduling mode is the start time of the next symbol of the last symbol occupied by the data channel scheduled using the first scheduling information, or another next symbol time of the last symbol occupied by the data channel scheduled using the first scheduling information. For example, the application time of the second scheduling mode may be the Q-th μs of the next symbol of the last symbol occupied by the data channel scheduled using the first scheduling information, where Q is a positive integer.

[00290] For example, each slot includes 14 symbols, and the first scheduling mode and the second scheduling mode are inter-slot scheduling, K0 in the first scheduling mode is 2, and K0 in the second scheduling mode is 1. For example, scheduling information is used for downlink data channel scheduling. As shown in FIG. 10a, the terminal detects a switch indication in slot 1. Before the switch indication, there is scheduling information 1 (including the location in the time domain where the switch indication is located). The scheduling information 1 is in slot 0, and the data channel called using the scheduling information 1 is located in the fifth to fourteenth symbols in slot 2. As shown by the dotted line in FIG. 10a, the application time of the second scheduling mode may be the next symbol after the fourteenth symbol in slot 2, for example, may be the first symbol in slot 3. For example, the length of each symbol is 71 μs. The time of application of the second scheduling mode may be, in particular, the start time of the first symbol in slot 3, for example, the 1st µs of the first symbol in slot 3, the 50th µs of the first symbol in slot 3, or the 71st µs of the first symbol in slot 3. This application is not expressly limited. In front of the location indicated by the dotted line in FIG. 10a, the first scheduling mode is used for scheduling a downlink data channel. For example, before the dashed line, scheduling information 1 is in slot 0, a downlink data channel scheduled using scheduling information 1 is received in slot 2, and a downlink data channel scheduled using scheduling information 2 is received in slot 4. After the dotted line in slot 5, a downlink data channel scheduled using scheduling information 3 is received.

[00291] (6.2) The application time of the second scheduling mode is the next slot of the slot occupied by the data channel scheduled using the first scheduling information.

[00292] The next slot of the slot occupied by the data channel planned using the first planning information may be a slot that is located after a slot occupied by a data channel planned using the first planning information, and which is located next to the slot occupied by the data channel planned Using the first information information, or can be any slot after the slot occupied by the data channel planned using the first information information. In this application, it is expressly not limited.

[00293] A slot in this embodiment of the present application may include a plurality of symbols. For example, one slot may include 12 or 14 symbols. When one slot includes a plurality of symbols, that the application time of the second scheduling mode is the next slot of the slot occupied by the data channel scheduled using the first scheduling information may include: The application time of the second scheduling mode is the start symbol in the next slot slot occupied by the data channel scheduled using the first scheduling information, or another symbol in the next slot of the slot occupied by the data channel scheduled using the first scheduling information. For example, the application time of the second scheduling mode is the Rth symbol in the next slot of the slot occupied by the data channel scheduled using the first scheduling information, where R is a positive integer. Alternatively, when one slot includes a plurality of symbols, and the duration of each symbol is tens of µs, that the application time of the second scheduling mode is the next slot of the slot occupied by the data channel scheduled using the first scheduling information may include: The application time of the second scheduling mode is the symbol start time (start symbol or any other symbol) in the next slot of the slot occupied by the data channel scheduled using the first scheduling information, or the application time of the second scheduling mode may be any other symbol time (start symbol or any other symbol) in the next slot of the slot occupied by the data channel scheduled using the first scheduling information. For example, the application time of the second scheduling mode is the Qth µs of a symbol (a start symbol or any other symbol) in the next slot of a slot occupied by the data channel scheduled using the first scheduling information, where Q is an integer.

[00294] For example, each slot includes 14 symbols, and the first scheduling mode and the second scheduling mode are inter-slot scheduling, K0 in the first scheduling mode is 2, and K0 in the second scheduling mode is 1. For example, scheduling information is used for downlink data channel scheduling. As shown in FIG. 10b, the terminal detects a switch indication in slot 1. Before the switch indication, there is scheduling information 1 (including the location in the time domain where the switch indication is located). The scheduling information 1 is located in slot 0, and the data channel called using the scheduling information 1 is located in the fifth to tenth symbols in slot 2. As shown by the dotted line in FIG. 10b, the application time of the second scheduling mode may be the next slot of slot 2, for example, may be the start time of slot 3. Specifically, when the slot includes 14 symbols, the application time of the second scheduling mode may be the start symbol in slot 3, for example, may be the first symbol in slot 3, may be the tenth symbol in slot 3, or may be the fourteenth symbol in slot 3. Alternatively, when the duration of each symbol is tens of µs, the second scheduling mode application time may be the start time of the first symbol in slot 3 , for example, may be the 1st μs of the first symbol in slot 3, may be the 10th μs of the first symbol in slot 3, or may be the 71st μs of the first symbol in slot 3. Before the location indicated by the dotted line in FIG. 10b, the first scheduling mode is used for scheduling the downlink data channel. For example, before the dashed line, scheduling information 1 is in slot 0, a downlink data channel scheduled using scheduling information 1 is received in slot 2, and a downlink data channel scheduled using scheduling information 2 is received in slot 4. After the dotted line in slot 5, a downlink data channel scheduled using scheduling information 3 is received.

[00295] (6.3) The application time of the second scheduling mode is the first scheduling information monitoring event after the time domain location occupied by the data channel scheduled using the first scheduling information.

[00296] Descriptions related to the scheduling information monitoring event are described in Method 1, and details are not described again. It should be noted that in (6.3), the first scheduling information monitoring event after the time domain location occupied by the data channel scheduled using the first scheduling information may be the scheduling information monitoring event that occurs for the first time after the time domain location occupied by the data channel, scheduled using the first scheduling information, or may be any other scheduling information monitoring event after the time domain location occupied by the data channel scheduled using the first scheduling information. For example, the first scheduling information monitoring event after the time domain location occupied by the data channel scheduled using the first scheduling information may be the Nth scheduling information monitoring event after the time domain location occupied by the data channel scheduled using the first scheduling information, where N is a positive integer.

[00297] In order to avoid the problem that the data channel cannot be correctly transmitted because the terminal cannot detect the PDCCH used for scheduling the data channel, the second scheduling mode takes effect when the first scheduling information monitoring event occurs after the location in the time domain occupied by the data channel scheduled using the first scheduling information.

[00298] When the first scheduling information monitoring event occupies a plurality of symbols, that the application time of the second scheduling mode is the first scheduling information monitoring event after the time domain location occupied by the data channel scheduled using the first scheduling information may include: Time application of the second scheduling mode is the start symbol of the first scheduling information monitoring event after the time domain location occupied by the data channel scheduled using the first scheduling information, or may be any other symbol in the first scheduling information monitoring event. after the time domain location occupied by the data channel scheduled using the first scheduling information. Alternatively, when the first scheduling information monitoring event occupies a plurality of symbols, and each symbol occupies tens of µs, that the application time of the second scheduling mode is the first scheduling information monitoring event after the time domain location occupied by the data channel scheduled using the first information scheduling may include: The application time of the second scheduling mode is the symbol start time (eg, start symbol or any other symbol) of the first scheduling information monitoring event after the time domain location occupied by the data channel scheduled using the first scheduling information, or the time application of the second scheduling mode is any other symbol moment (eg, start symbol or any other symbol) of the first scheduling information monitoring event after the time domain location occupied by the data channel, schedule calculated using the first scheduling information. In this application, it is expressly not limited.

[00299] For example, each slot includes 14 symbols, and the first scheduling mode and the second scheduling mode are inter-slot scheduling, K0 in the first scheduling mode is 2, and K0 in the second scheduling mode is 1. For example, scheduling information is used for downlink data channel scheduling. As shown in FIG. 10c, the terminal detects a switch indication in slot 1. Before the switch indication, there is scheduling information 1 (including the location in the time domain where the switch indication is located). The scheduling information 1 is located in slot 0, and the data channel called using the scheduling information 1 is located in the fifth to tenth symbols in slot 2. The first monitoring event of the time domain location scheduling information occupied by the data channel scheduled using the scheduling information 1 , located in slot 4. As shown by the dotted line in FIG. 10c, the application time of the second scheduling mode may be the start time of slot 4. Specifically, when the slot includes 14 symbols, the application time of the second scheduling mode may be the start symbol in slot 4, for example, may be the first symbol in slot 4, may be the tenth symbol in slot 4, or may be the fourteenth symbol in slot 4. Alternatively, when the length of each symbol is tens of µs, the second scheduling mode application time may be the start time of the first symbol in slot 4, for example, may be the 1st µs of the first symbol in slot 4 may be the 10th μs of the first symbol in slot 4, or may be the 71st μs of the first symbol in slot 4. Before the location indicated by the dotted line in FIG. 10c, the first scheduling mode is used for scheduling the downlink data channel. For example, before the dashed line, scheduling information 1 is in slot 0, a downlink data channel scheduled using scheduling information 1 is received in slot 2, and a downlink data channel scheduled using scheduling information 2 is received in slot 4. After the dotted line in slot 5, a downlink data channel scheduled using scheduling information 3 is received.

[00300] In method 6, when the scheduling information is used for scheduling the downlink data channel to ensure transmission reliability of the downlink data channel, after the terminal sends the feedback information of the downlink data channel scheduled using the scheduling information, the second scheduling mode comes into effect. In particular, the time of application of the second scheduling mode can be described in (6.4), (6.5) or (6.6):

[00301] (6.4) The application time of the second scheduling mode is the next symbol of the last symbol occupied by the downlink data channel feedback information scheduled using the first scheduling information.

[00302] The next symbol of the last symbol occupied by the downlink data channel feedback information scheduled using the first scheduling information may be a symbol adjacent to the last symbol occupied by the downlink data channel feedback information scheduled using the first scheduling information , or may be any symbol after the last symbol occupied by the downlink data channel feedback information scheduled using the first scheduling information. In this application, it is expressly not limited.

[00303] The symbol in this embodiment of the present application has a certain length, and the duration of one symbol may be tens of microseconds. For example, a symbol may be 71 µs long. When the symbol length is tens of µs, that the application time of the second scheduling mode is the next symbol of the last symbol occupied by the downlink data channel feedback information scheduled using the first scheduling information may include: The application time of the second scheduling mode is the next symbol start time of the last symbol occupied by the downlink data channel feedback information scheduled using the first scheduling information, or any other next symbol time of the last symbol occupied by the downlink data channel feedback information scheduled using the first scheduling information. For example, the application time of the second scheduling mode may be Q-th µs of the next symbol of the last symbol occupied by the downlink data channel feedback information scheduled using the first scheduling information, where Q is a positive integer.

[00304] For example, each slot includes 14 symbols, and the first scheduling mode and the second scheduling mode are inter-slot scheduling, K0 in the first scheduling mode is 2, and K0 in the second scheduling mode is 1. For example, scheduling information is used for downlink data channel scheduling. As shown in FIG. 11a, the terminal detects a switch indication in slot 1. Before the switch indication, there is scheduling information 1 (including the location in the time domain where the switch indication is located). The scheduling information 1 is located in slot 0, and the downlink data channel activated using the scheduling information 1 is located in the first to seventh symbols in slot 2. The downlink data channel feedback information is located in the twelfth symbol in slot 2. As shown by a dotted line in Fig. 11a, the application time of the second scheduling mode may be the next symbol after the twelfth symbol in slot 2, for example, may be the thirteenth symbol in slot 2. For example, the length of each symbol is 71 μs. The time of application of the second scheduling mode may be, in particular, the start of the thirteenth symbol in slot 2, for example, the 1st µs of the thirteenth symbol in slot 2, the 50th µs of the thirteenth symbol in slot 2, or the 71st µs of the thirteenth symbol in slot 2. In this application, this is not expressly limited. In front of the location indicated by the dotted line in FIG. 11a, the first scheduling mode is used for scheduling a downlink data channel. For example, before the dashed line, scheduling information 1 is in slot 0, a downlink data channel scheduled using scheduling information 1 is received in slot 2, and a downlink data channel scheduled using scheduling information 2 is received in slot 4. After the dotted line in slot 5, a downlink data channel scheduled using scheduling information 3 is received.

[00305] (6.5) The application time of the second scheduling mode is the next slot of the slot occupied by the downlink data channel feedback information scheduled using the first scheduling information.

[00306] The next slot of the slot occupied by the downlink data channel feedback signal scheduled using the first scheduling information may be a slot which is after the slot occupied by the downlink data channel feedback signal scheduled using the first scheduling information, and which is next to the slot occupied by the downlink data channel feedback signal scheduled using the first scheduling information, or may be any slot after the slot occupied by the downlink data channel feedback signal scheduled using the first scheduling information. In this application, it is expressly not limited.

[00307] The slot in this embodiment of this application may include many characters. For example, one slot may include 12 or 14 characters. Когда один слот включает в себя множество символов, то, что время применения второго режима планирования является следующим слотом слота, занятого информацией обратной связи канала данных нисходящей линии связи, запланированного с использованием первой информации планирования, может включать в себя: Время применения второго режима планирования является the initial symbol in the next slot of the slot occupied by the feedback signal of the data channel of the descending communication line planned using the first information information; Or it is another symbol in the next slot of the slot occupied by the feedback signal of the data channel of the descending communication line planned using the first information information. For example, the time of application of the second planning mode can be the R -Mic symbol in the next slot of the slot, which is engaged in the feedback signal of the data channel, planned using the first planning information, where R is a positive integer. As an alternative, when one slot includes many symbols, and the duration of one symbol is dozens of ISS, the fact that the time of application of the second planning mode is the next slot of the slot engaged in the feedback of the data channel for the downward communication line, planned using the first information planning information It may include: the time of application of the second planning mode is the initial moment of the symbol (the initial symbol or any other symbol) in the next slot of the slot of the feedback from the data channel of the descending line of communication planned using the first information information; Or the time of application of the second planning regime can be any moment of the symbol (initial symbol or any other symbol) in the next slot of the slot occupied by the information of the data channel of the descending communication line planned using the first information information. For example, the time of application of the second planning regime is a Q -I MKS symbol (the initial symbol or any other symbol), where Q is an integer.

[00308] For example, each slot includes 14 symbols, and the first scheduling mode and the second scheduling mode are inter-slot scheduling, K0 in the first scheduling mode is 2, and K0 in the second scheduling mode is 1. For example, scheduling information is used for downlink data channel scheduling. As shown in FIG. 11b, the terminal detects a switch indication in slot 1. Before the switch indication, there is scheduling information 1 (including the location in the time domain where the switch indication is located). The scheduling information 1 is located in slot 0, and the downlink data channel activated using the scheduling information 1 is located in the first to seventh symbols in slot 2. The downlink data channel feedback information is located in the twelfth symbol in slot 2. As shown by a dotted line in Fig. 11b, the application time of the second scheduling mode may be the next slot of slot 2, for example, may be the start time of slot 3. Specifically, when the slot includes 14 symbols, the application time of the second scheduling mode may be the start symbol in slot 3, for example, may be the first symbol in slot 3, may be the tenth symbol in slot 3, or may be the fourteenth symbol in slot 3. Alternatively, when the duration of each symbol is tens of µs, the second scheduling mode application time may be the start time of the first symbol in slot 3 , for example, may be the 1st μs of the first symbol in slot 3, may be the 10th μs of the first symbol in slot 3, or may be the 71st μs of the first symbol in slot 3. Before the location indicated by the dotted line in FIG. 11b, the first scheduling mode is used for scheduling a downlink data channel. For example, before the dashed line, scheduling information 1 is in slot 0, a downlink data channel scheduled using scheduling information 1 is received in slot 2, and a downlink data channel scheduled using scheduling information 2 is received in slot 4. After the dotted line in slot 5, a downlink data channel scheduled using scheduling information 3 is received.

[00309] (6.6) The application time of the second scheduling mode is the first scheduling information monitoring event after the time domain location occupied by the downlink data channel feedback information scheduled using the first scheduling information.

[00310] Descriptions related to the scheduling information monitoring event are described in Method 1, and details are not described again. It should be noted that in (6.6), the first scheduling information monitoring event after the time domain location occupied by the downlink data channel feedback information scheduled using the first scheduling information may be the scheduling information monitoring event that occurs for the first time after the location in the time domain occupied by the downlink data channel feedback information scheduled using the first scheduling information, or may be any other scheduling information monitoring event after the time domain location occupied by the downlink data channel feedback information scheduled using the first planning information. For example, the first scheduling information monitoring event after the time domain location occupied by the downlink data channel feedback information scheduled using the first scheduling information may be the N-th scheduling information monitoring event after the time domain location occupied by the channel feedback information. downlink data scheduled using the first scheduling information, where N is a positive integer.

[00311] In order to avoid the problem that the data channel cannot be correctly transmitted because the terminal cannot detect the PDCCH used for scheduling the data channel, the second scheduling mode takes effect when the first scheduling information monitoring event occurs after the location in of the time domain occupied by the downlink data channel feedback signal scheduled using the first scheduling information.

[00312] When the first scheduling information monitoring event occupies a plurality of symbols, that the application time of the second scheduling mode is the first scheduling information monitoring event after the time domain location occupied by the downlink data channel feedback information scheduled using the first scheduling information, may include: The application time of the second scheduling mode is the start symbol of the first scheduling information monitoring event after the time domain location occupied by the downlink data channel feedback signal scheduled using the first scheduling information, or may be any other symbol of the first monitoring event scheduling information after the time domain location occupied by the downlink data channel feedback signal scheduled using the first scheduling information. Alternatively, when the first scheduling information monitoring event occupies a plurality of symbols, and each symbol occupies tens of µs, that the application time of the second scheduling mode is the first scheduling information monitoring event after the time domain location occupied by the downlink data channel feedback information , scheduled using the first scheduling information, may include: The application time of the second scheduling mode is the symbol start time (eg, start symbol or any other symbol) of the first scheduling information monitoring event after the time domain location occupied by the data channel feedback signal downlink scheduled using the first scheduling information, or the application time of the second scheduling mode is any other symbol instant (eg, start symbol or any other symbol) of the first mon event. iterating the scheduling information after the time domain location occupied by the downlink data channel feedback signal scheduled using the first scheduling information. In this application, it is expressly not limited.

[00313] For example, each slot includes 14 symbols, and the first scheduling mode and the second scheduling mode are inter-slot scheduling, K0 in the first scheduling mode is 2, and K0 in the second scheduling mode is 1. For example, scheduling information is used for planning the data channel of the descending line of communication. As shown in FIG. 11c, the terminal detects a switch indication in slot 1. Before the switch indication, there is scheduling information 1 (including the location in the time domain where the switch indication is located). The scheduling information 1 is located in slot 0, and the downlink data channel activated using the scheduling information 1 is located in the first to seventh symbols in slot 2. The downlink data channel feedback information is located in the fourteenth symbol in slot 2. First a scheduling information monitoring event (scheduling information 3) of the time domain location occupied by the downlink data channel feedback information is located in slot 4. As shown by the dashed line in FIG. 11c, the application time of the second scheduling mode may be the start time of slot 4. Specifically, when the slot includes 14 symbols, the application time of the second scheduling mode may be the start symbol in slot 4, for example, may be the first symbol in slot 4, may be the tenth symbol in slot 4, or may be the fourteenth symbol in slot 4. Alternatively, when the length of each symbol is tens of µs, the second scheduling mode application time may be the start time of the first symbol in slot 4, for example, may be the 1st µs of the first symbol in slot 4 may be the 10th μs of the first symbol in slot 4, or may be the 71st μs of the first symbol in slot 4. Before the location indicated by the dotted line in FIG. 11c, the first scheduling mode is used for scheduling the downlink data channel. For example, before the dashed line, scheduling information 1 is in slot 0, a downlink data channel scheduled using scheduling information 1 is received in slot 2, and a downlink data channel scheduled using scheduling information 2 is received in slot 4. After the dotted line in slot 5, a downlink data channel scheduled using scheduling information 3 is received.

[00314] In Method 6, the first scheduling information may be specifically scheduling information that schedules the last transmitted downlink data channel in all scheduling information no later than the switch indication to ensure that the second scheduling mode takes effect after , as all downlink data channels scheduled using scheduling information that is transmitted no later than the switch indication.

[00315] It should be noted that the rules for determining when to apply the second scheduling mode from method 1 to method 6 may be predefined in the protocol. Once the terminal receives the PDCCH including the switch indication, the terminal may perform a protocol search and determine when to apply the second scheduling mode according to the protocol. In addition, any one or combination of Manner 1 to Method 6 can be used to determine when to apply the second scheduling mode, i.e. the latest time in the time defined by any one or more methods 1 to 6 can be used as the time to apply the second planning mode. For example, the latest time shown in (1.1) of method 1, the time shown in (2.1) of method 2, and the time shown in (4.1) of method 4 can be used as the application time of the second scheduling mode. Alternatively, the latest time shown in (1.1) of method 1, the time shown in (2.1) of method 2, the time shown in (3.1) of method 3, the time shown in (4.1) of method 4, the time shown in method 5, and the time shown in (6.1) of method 6 is used as the application time of the second scheduling mode, and the like.

[00316] In addition to Methods 1 through 6 above, the network device may further indicate when to apply the second scheduling mode to the terminal via dynamic signaling, as described in the following Method 7.

[00317] Method 7: The terminal accepts the application of the application sent by the network device, where the indication of the application can be used to indicate the time of application of the second planning mode; And the terminal determines the time of application of the second planning regime based on an indication of application.

[00318] An indication of the application may be included in the PDCCH or PDSCH. For example, the application indication may be a DCI on the PDCCH or a DCI included on the PDCCH, or the application indication may be a MAC CE on the PDSCH or a MAC CE included on the PDSCH. In this application, it is expressly not limited.

[00319] Thus, the network device can indicate to the terminal when to apply the second scheduling mode. It's simple and easy to implement.

[00320] It should be noted that in this embodiment of the present application, after determining the application time of the second scheduling mode, the terminal may schedule the data channel and/or the reference signal using the second scheduling mode when it is the time to apply the second scheduling mode or after the time to apply the second scheduling mode. planning mode. The terminal stops the second scheduling mode only when the terminal again receives a new switch indication, and the new switch indication is used to instruct the terminal to switch from the second scheduling mode to the first scheduling mode.

[00321] The method for determining when to apply the second scheduling mode in the above solution can be applied to a scenario in which the subcarrier spacing of the BWP in which the terminal operates remains unchanged. In an actual application, the BWP (uplink BWP and/or downlink BWP) on which the terminal operates may be switched. The numerology of the BWP used after the switch may be different from the numerology of the BWP used before the switch. The subcarrier spacing of the BWP used after handover may be different from the subcarrier spacing of the BWP used before handover.

[00322] When the BWP subcarrier spacing is different, the slot lengths corresponding to the BWP are different. Therefore, when the terminal's scheduling mode is switched, if the BWP in which the terminal operates is also switched, the application time determined by the above method needs to be adjusted based on the BWP system parameter to obtain the application time of the second scheduling mode. Specifically, the second scheduling mode application timing process is described as follows.

[00323] When the switch indication in step 501 is included in the PDCCH, and the switch indication is further used to direct the terminal to switch from the first BWP to the second BWP, the terminal determines the time to apply the second scheduling mode to the target BWP based on slot N in which the PDCCH is located applicable minimum displacement of the slot and the target coefficient.

[00324] The applicable minimum slot offset may be the applicable minimum value of K0 when the terminal receives a switch indication.

[00325] N is a natural number. For example, N can be 0 or 1.

[00326] The target coefficient is determined based on the numerology of the target BWP and the numerology of the first downlink BWP. The first downlink BWP is the active downlink BWP when the terminal receives a switch indication.

[00327] The target BWP may be an uplink BWP or may be a downlink BWP. When the second scheduling mode is used to indicate an offset between a slot in which the PDCCH is located and a slot in which the uplink data channel scheduled using the PDCCH is located, the target BWP is an uplink BWP. When the second scheduling mode is used to indicate an offset between a slot in which the PDCCH is located and a slot in which the downlink data channel scheduled using the PDCCH is located, the target BWP is the downlink BWP.

[00328] For example, the target BWP may be determined based on the scheduling mode and switching status of the BWP. For example,

the first BWP is the first downlink BWP, the second BWP is the second downlink BWP, the first scheduling mode is the first downlink scheduling mode, the second scheduling mode is the second downlink scheduling mode, and the target BWP is the second downlink BWP.

[00329] The first BWP is the first downlink BWP, the second BWP is the second downlink BWP, the first scheduling mode is the first uplink scheduling mode, the second scheduling mode is the second uplink scheduling mode, and the target BWP is the first uplink BWP communication lines.

[00330] The first BWP is the first uplink BWP, the second BWP is the second uplink BWP, the first scheduling mode is the first downlink scheduling mode, the second scheduling mode is the second downlink scheduling mode, and the target BWP is the first downlink BWP communication lines.

[00331] The first BWP is the first uplink BWP, the second BWP is the second uplink BWP, the first scheduling mode is the first uplink scheduling mode, the second scheduling mode is the second uplink scheduling mode, and the target BWP is the second uplink BWP communication lines.

[00333] For example, the application time of the second scheduling mode is not earlier than the Qth slot. For example, the application time of the second scheduling mode may be the start location of the Qth slot or the start symbol in the Qth slot. Alternatively, the application time of the second scheduling mode may be any other symbol in the Qth slot, another slot after the Qth slot, or the like. It's not limited.

[00336] It should be noted that the terminal can determine, in a scenario in which the uplink scheduling mode, downlink scheduling mode, uplink BWP and downlink BWP are switched, with reference to the above method, the application time of the switched scheduling mode. Details are not described.

[00337] Next, M=max[1, the minimum value of K0] is used as an example to describe, with reference to the following cases 1-5, the application time of the scheduling mode in the scenario in which the scheduling mode of the terminal and the BWP in which the terminal operates, switch.

In this case, the uplink BWP is not switched, and the uplink BWP in which the terminal operates is still the first uplink BWP activated when the terminal receives the switch indication. Therefore, what the terminal determines when to apply the second uplink scheduling mode includes: The terminal determines when to apply the second uplink scheduling mode on the first uplink BWP based on slot N in which the PDCCH is located, the applicable minimum slot offset and coefficient

In this case, what the terminal can determine with reference to Case 1 is the application time of the second downlink scheduling mode includes: The terminal determines the application time of the second downlink scheduling mode on the second downlink BWP based on slot N in which it is located PDCCH, applicable minimum slot offset and coefficient

.

[00364] In other words, the application time of the second downlink scheduling mode and the application time of the second uplink scheduling mode can be determined with reference to the processes described in cases 1 and 2. Details are not repeated.

[00365] It should be noted that in cases 1 to 5, the terminal may be located in a frequency division duplexing (FDD) system. In case 5, the terminal may be located in a time division duplexing (TDD) system. In the TDD system, the uplink BWP and the downlink BWP are switched in pairs. Once the uplink BWP is switched, the downlink BWP is definitely switched. In other words, at the same time, if the uplink BWP switches, the downlink BWP inevitably switches. In the FDD system, uplink BWP switching and downlink BWP switching are separated, and uplink BWP switching or downlink BWP switching can be performed at the same time.

[00366] In addition, the content indicated by the network device to the terminal is not limited in this embodiment of the present application. In addition to instructing the terminal to switch scheduling mode and/or switch BWP, the switch indication sent by the network device to the terminal may optionally be used to indicate one or more of the following parameters: terminal PDCCH skipping, period during which the terminal monitors the PDCCH, parameter terminal with multiple inputs and multiple outputs (multi-input multi-out, MIMO), search space and / or CORESET tracked by the terminal, etc. After receiving one or more parameters specified by the network device, the terminal may determine the application time of these parameters and use these parameters when the determined application time arrives.

[00367] In particular, the application time of one or more parameters may be the same as the application time of the second scheduling mode. For example, when the terminal's BWP is not switched, the application time of the above one or more parameters may be no earlier than the (N+max(1, minimum value of K0)) th slot, where N is the slot in which the PDCCH resides, including the switch indication, received by the terminal.

[00368] PDCCh pass may indicate that the terminal passes one or more slots/sucaders/monitoring events (Monitor OCCASION, MO) for tracking the PDCC used for data planning.

[00369] The period during which the terminal monitors the PDCCH may be the period during which the terminal monitors the PDCCH used for data scheduling.

[00370] The MIMO parameter of a terminal can be the number of transmit/receive antennas (antenna), the number of antenna ports (antenna port), the number of transport layers (layer), or the maximum number of transport layers of the terminal.

[00371] The search space and/or CORESET tracked by the terminal may indicate the CORESET and/or search space that should be tracked by the terminal to track the PDCCH used for data scheduling.

[00372] In embodiments of the present application, a network device may indicate a minimum BWP slot offset for a terminal such that the terminal schedules a data channel based on the network device indication. In particular, the process may include the following steps.

[00373] The terminal receives minimum slot offset indication information sent by the network device. The minimum slot offset indication information is used to indicate the minimum slot offset of the target BWP. The terminal determines the minimum slot offset of the target BWP based on the indication information of the minimum slot offset and the numerology of the target BWP. The target BWP's minimum slot offset is based on the numerology of the target BWP.

[00374] The target BWP may be an uplink BWP or may be a downlink BWP. It's not limited. Further, the target BWP may be an active uplink BWP or an active downlink BWP when the terminal receives the minimum slot offset indication information, or may be an uplink BWP or a downlink BWP to which the terminal is to switch.

[00375] The minimum slot offset of the target BWP may be the slot offset between the slot in which the PDCCH is located and the slot in which the data channel scheduled using the PDCCH on the target BWP is located. When the target BWP is an uplink BWP, the minimum slot offset of the target BWP is the slot offset between the slot in which the PDCCH is located and the slot in which the uplink data channel scheduled using the PDCCH on the uplink BWP is located. When the target BWP is a downlink BWP, the minimum slot offset of the target BWP is the slot offset between the slot in which the PDCCH is located and the slot in which the downlink data channel scheduled using the PDCCH on the downlink BWP is located. .

[00376] That the minimum slot offset of the target BWP is based on the numerology of the target BWP can also be described as that the minimum slot offset of the target BWP corresponds to the numerology of the target BWP, the minimum slot offset of the target BWP is equally related to the numerology of the target BWP, the minimum slot offset of the target The BWP is related to the numerology of the target BWP, the minimum slot offset of the target BWP uses the numerology of the target BWP as a reference value, and so on.

[00377] The minimum slot offset of the target BWP finally determined by the terminal may be the duration of the offset that is between the slot in which the PDCCH is located and the slot in which the data channel scheduled using the PDCCH is located and which is related to the target BWP. The unit of the minimum slot offset of the target BWP finally determined by the terminal may be ms.

[00378] For example, it is assumed that the numerology of the target BWP is 1, the subcarrier spacing of the target BWP is 30 kHz, and the length of one slot of the target BWP is 0.5 ms. In this case, if the minimum slot offset of the target BWP indicated using the minimum slot offset indication information is two slots, the terminal can determine, based on the minimum slot offset indication information and the system parameter numerology of the target BWP, that the minimum slot offset of the target BWP is 2× 0.5ms=1ms.

[00379] In an exemplary implementation, the minimum slot offset indication information includes a value corresponding to the minimum slot offset of the target BWP. In other words, the network device can directly indicate the minimum slot offset value for the terminal, so that the terminal directly determines the minimum slot offset of the target BWP based on the minimum slot offset value of the target BWP and the numerology of the target BWP.

[00380] The minimum slot offset value of the target BWP may be the number of slots in the offset that is between the slot in which the PDCCH is located and the slot in which the data channel scheduled using the PDCCH is located and which is on the target BWP. For example, when the target BWP is a downlink BWP, the network device may indicate the minimum value of K0 to the terminal. When the target BWP is an uplink BWP, the network device may indicate the minimum value of K2 to the terminal.

[00381] It should be noted that in this embodiment of the present application, the minimum slot offset of the target BWP is not limited to indication using K0 or K2, and the minimum slot offset of the BWP may be indirectly indicated in another way. For details, refer to the following several possible implementations.

[00382] In yet another possible implementation, the minimum slot offset indication information includes a value corresponding to the reference minimum slot offset. That the terminal determines the minimum slot offset of the target BWP based on the indication information of the minimum slot offset and the numerology of the target BWP includes: The terminal determines the minimum slot offset of the target BWP based on a value corresponding to the reference minimum slot offset, the reference numerology and the numerology of the target BWP.

[00383] The value corresponding to the reference minimum slot offset may be the minimum slot offset value corresponding to the reference numerology, or may be described as that the value corresponding to the reference minimum slot offset is the value of the minimum slot offset corresponding to the BWP reference. When the target BWP is an uplink BWP, the value of the reference minimum slot offset may be the reference minimum value K0. When the target BWP is a downlink BWP, the value of the reference minimum slot offset may be the minimum value of K2.

и значения, соответствующего эталонному минимальному смещению слота, количество слотов в смещении, которое находится между слотом, в котором расположен PDCCH, и слотом, в котором расположен канал данных, запланированный с использованием PDCCH, и который относится к целевой BWP. Затем терминал определяет на основе нумерологии целевой BWP и количества слотов в смещении, которое находится между слотом, в котором расположен PDCCH, и слотом, в котором расположен канал данных, запланированный с использованием PDCCH, и который относится к целевой BWP, длительностью смещения, которое находится между слотом, в котором расположен PDCCH, и слотом, в котором расположен канал данных, запланированный с использованием PDCCH, и который относится к целевой BWP.[00384] For example, the terminal may determine based on the product of the coefficient

and a value corresponding to the reference minimum slot offset, the number of slots in the offset that is between the slot in which the PDCCH is located and the slot in which the data channel scheduled using the PDCCH is located and which is related to the target BWP. Then, based on the numerology of the target BWP and the number of slots in the offset that is between the slot in which the PDCCH is located and the slot in which the data channel scheduled using the PDCCH is located and which is related to the target BWP, the terminal determines the duration of the offset that is between the slot in which the PDCCH is located and the slot in which the data channel scheduled using the PDCCH is located and which belongs to the target BWP.

слоту. Поскольку нумерология целевой BWP равна 0, а один слот целевого BWP составляет 1 мс, минимальное смещение слота целевой BWP составляет 1 мс.[00386] For example, if the reference minimum slot offset is the reference minimum value K0=2, the reference numerology is 1, and the target BWP numerology is 0, the target BWP minimum offset is

slot. Since the numerology of the target BWP is 0 and one slot of the target BWP is 1 ms, the minimum slot offset of the target BWP is 1 ms.

[00387] In yet another possible implementation, the minimum slot offset indication information includes a first index. That the terminal determines the minimum slot offset of the target BWP based on the indication information of the minimum slot offset and the numerology of the target BWP includes: The terminal determines the minimum slot offset of the target BWP based on the first index, the first match and the numerology of the target BWP.

[00388] For example, the terminal may first determine, based on the first index and the first match, the number of slots corresponding to the minimum slot offset of the target BWP, and then determine, based on the number of slots corresponding to the minimum slot offset of the target BWP and the numerology of the target BWP, the duration corresponding to the minimum offset target BWP slot.

[00389] The first match includes a match between the index and the minimum BWP slot offset. The minimum slot offset included in the first correspondence may be the minimum slot offset of the downlink BWP, or may be the minimum slot offset of the uplink BWP. It's not limited. For example, the minimum BWP slot offset included in the first correspondence may be the minimum downlink BWP value K0 or may be the minimum uplink BWP value K2.

[00390] The first match may be a match in the form of an array, or may be a match in the form of a list. For example, the first match could be an array: index 0 {min K0 for BWP 1 is 0, min K0 for BWP 2 is 0} index 1 {min K0 for BWP 1 is 2, min K0 for BWP 2 is 1 }. Alternatively, the first match is shown in the following Table 3. This is not limited.

[00391] For example, the first match is a list match, and the minimum BWP slot offset in the first match is the downlink minimum BWP value K0.

This is standard numerology.

[00397] The second match includes a match between the index and the reference minimum slot offset. The reference minimum slot offset is described above. When the target BWP is a downlink BWP, the reference numerology may be the numerology of the reference DL BWP and the reference minimum slot offset may be the reference minimum value K0. When the target BWP is an uplink BWP, the reference numerology may be the numerology of the reference UL BWP and the reference minimum slot offset may be the reference minimum K2.

As shown in Table 5, when the index is 0, the corresponding reference minimum value of K0 is 0. When the index is 1, the corresponding reference minimum value of K0 is 1. When the index is 2, the corresponding reference minimum value of K0 is 2.
