Description

Scheduling switching method and device

The present application claims priority of chinese patent application with the application number 201910582611.4, entitled "a method and apparatus for scheduling handover" filed by the national intellectual property office on 29/06/29/2019, the entire contents of which are incorporated herein by reference.

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a scheduling switching method and device.

Background

In Rel-15 specified by 3rd generation standardization organization (3 GPP), when a base station schedules a data channel of a terminal, the base station first transmits scheduling information by which the base station schedules a PDSCH of the terminal (e.g., a Physical Downlink Shared Channel (PDSCH) transmitted via a Physical Downlink Control Channel (PDCCH), or a PUSCH of the terminal via a physical downlink shared channel (PUSCH) transmitted via the PDCCH), and the scheduling information may indicate transmission parameters of the data channel, such as: the time domain resource position of the data channel, and the like, and the terminal can receive the data channel at the time domain resource position of the data channel according to the indication of the scheduling information.

The scheduling process can be divided into the following two scheduling modes according to the time domain position relationship between the PDCCH and the data channel: simultaneous slot scheduling (single slot scheduling), wherein the PDCCH and the data channel are positioned in the same time slot; cross-slot scheduling (cross-slot scheduling), the data channel and the PDCCH are located in different slots, such as: the terminal may receive a data channel at a time slot next to the time slot occupied by the PDCCH, etc.

In order to reduce the power consumption of the terminal and ensure good user experience, the 3rd generation mobile communication standardization organization (3 GPP) has established a topic for saving the power consumption of the terminal in Rel-16, and discusses that the power consumption of the terminal is reduced by dynamically switching a scheduling mode, such as: the network device dynamically indicates a minimum available value (or referred to as a minimum available value) to the terminal, and then indicates a specific value in the scheduling information when the network device schedules a data channel of the terminal. Under normal conditions, the specific value is not less than the minimum available value, the terminal determines the time slot position of the data channel scheduled by the PDCCH according to the specific value indicated by the scheduling information, and receives the PDSCH or sends the PUSCH at the determined time slot position. For example, the network device indicates the minimum available value of K0 to the terminal to be 2, and when the network device schedules the terminal for PDSCH transmission, the value of K0 indicated in the scheduling information is not less than 2, for example: the indicated value of K0 may be 2 or 3 or 4, etc.

However, in practical applications, a specific value indicated in the scheduling information may be smaller than the minimum available value, and in this case, how the terminal handles is not specified in the prior art.

Detailed Description

Before describing the embodiments of the present application, some terms referred to in the embodiments of the present application are explained to facilitate understanding of the methods provided by the embodiments of the present application:

a Physical Downlink Control Channel (PDCCH) is mainly used for carrying Downlink Control Information (DCI), and the DCI may include common control information (e.g., system information) and user-specific information (e.g., downlink resource allocation indication, uplink scheduling, random access response, uplink power control parameter, etc.). The PDCCH may schedule data channels through the DCI it carries, such as: the DCI may be used to indicate a transmission parameter of a data channel (e.g., a time domain resource location of the data channel, etc.), before the data channel is transmitted, the network device may send the PDCCH to the terminal, and after the terminal receives the PDCCH, the terminal may demodulate the DCI in the PDCCH first and then receive or send the data channel on the time domain resource location indicated by the DCI. Further, the PDCCH may also indicate a time domain resource location of a channel state information reference signal (CSI-RS) through DCI carried by the PDCCH to trigger transmission of an aperiodic (non-periodic) CSI-RS.

A data channel, which may be used to carry data. In the 3GPP protocol, data channels are divided into: a Physical Uplink Shared Channel (PUSCH) (alternatively referred to as an uplink data channel) and a Physical Downlink Shared Channel (PDSCH) (alternatively referred to as a downlink data channel). The PUSCH is used to carry data (or referred to as uplink data) transmitted from the terminal to the network device, and the PDSCH is used to carry data (or referred to as downlink data) transmitted from the network device to the terminal.

And the CSI-RS is used for the terminal to measure the channel state between the terminal and the network equipment, and can comprise one or more channel state measurement resources. For example, the network device may send DCI for indicating a time domain resource location of the CSI-RS and the CSI-RS to the terminal, where the terminal receives the CSI-RS at the time domain resource location indicated by the DCI, measures a channel state measurement resource included in the CSI-RS, and reports Channel State Information (CSI) to the network device according to a measurement result.

When the PDCCH schedules a data channel, the time slot occupied by the PDCCH may be the same as or different from the time slot occupied by the data channel scheduled by the PDCCH. In the 3GPP protocol, according to the conditions of the time slot occupied by the PDCCH and the time slot occupied by the data channel scheduled by the PDCCH, the scheduling manner can be divided into: simultaneous slot scheduling (single slot scheduling), cross-slot scheduling (cross-slot scheduling). The same time slot scheduling means that the PDCCH and a data channel scheduled by the PDCCH are positioned in the same time slot, and the cross-time slot scheduling means that the PDCCH and the data channel scheduled by the PDCCH are positioned in different time slots.

In the 3GPP protocol, it is indicated by the value of K0 that the PDCCH and its scheduled PDSCH are scheduled simultaneously or across slots. The value K0 is a time slot difference between a time slot occupied by the PDCCH and a time slot occupied by the PDSCH scheduled by the PDCCH, and the value K0 has a value set, and the value set is configured to the terminal by the network device, for example, the value set may be {0, 1, 2 … … }. If K0 is 0, it means that PDCCH and PDSCH are in the same time slot, i.e. "simultaneous slot scheduling". If K0>0, it indicates that the PDCCH is not in the same time slot as the PDSCH, i.e., "cross-slot scheduling". The network device may directly indicate the value K0 to the terminal, or configure a Time Domain Resource Allocation (TDRA) table for the terminal, where the TDRA table includes an index value (index) and a K0 value corresponding to the index value, and the network device may indirectly indicate the value K0 to the terminal by indicating the index value to the terminal.

For example, the following table one is a schematic diagram of a TDRA table configured by the network device for the terminal when the PDCCH schedules the PDSCH, where the TDRA table includes a corresponding relationship between an index value and a K0 value, and as shown in table one, when the index value is 0, the K0 value is 0; when the index value is 1, the value of K0 is 1; when the index value is 2, the value of K0 is 1. When the network device schedules the PDSCH to the terminal through the PDCCH, the network device may configure a TDRA table shown in table one to the terminal, and subsequently, if the network device indicates an index value 1 to the terminal, the terminal may look up table one by taking the index value as 1 as an index, and determine that a K0 value corresponding to the index value 1 is 1, and the PDCCH and the PDSCH are in different time slots, that is, cross-slot scheduling.

When the PDCCH is used for scheduling the PUSCH, the PDCCH and the scheduled PUSCH may be in the same time slot, i.e., simultaneous slot scheduling, or in different time slots, i.e., cross-slot scheduling. In the 3GPP protocol, it is indicated by the value of K2 that the PDCCH is scheduled with its scheduled PUSCH in a simultaneous slot scheduling or a cross-slot scheduling. The value K2 is a time slot difference between a time slot occupied by the PDCCH and a time slot occupied by the scheduled PUSCH, and the value K2 has a value set, where the value set is configured to the terminal by the network device, and may be {0, 1, 2 … … }, for example. If K2 is 0, it indicates that PDCCH and PUSCH are in the same slot, i.e. "simultaneous slot scheduling". If K2>0, it indicates that PDCCH and PUSCH are not in the same time slot, i.e. "cross-slot scheduling". The network device may directly indicate the value K2 to the terminal, or the network device configures a TDRA table for the terminal, where the TDRA table includes an index value (index) and a value K2 corresponding to the index value, and the network device may indirectly indicate the value K2 to the terminal by indicating the index value to the terminal.

For example, the following table two is a schematic diagram of a TDRA table configured by the network device for the terminal when the PDCCH schedules the PUSCH, where the TDRA table includes a corresponding relationship between an index value and a K2 value, and as shown in table two, when the index value is 0, the K2 value is 0; when the index value is 1, the value of K2 is 2. When the network device schedules the PUSCH to the terminal through the PDCCH, the network device may configure a TDRA table shown in table two to the terminal, and subsequently, if the network device indicates an index value 1 to the terminal, the terminal may use the index value 1 as an index, look up table two, determine that a K2 value corresponding to the index value 1 is 2, the PDCCH and the PDSCH are in different time slots, and the difference between the PDCCH and the PDSCH is 2 time slots, that is, cross-slot scheduling.

It should be noted that table one and table two are only exemplary tables, and table one may include other K0 values and other contents besides those shown in the tables, such as: start and length indication values (starting and length indication values), mapping types (mapping types), and the like may also be included, which is not limited in the present application. Other K2 values or other content may also be included in table two, such as: the K2 values 0, 1, etc. may also be included in table two, as well as start and length indication values, mapping type, etc.

When the PDCCH is used for triggering the CSI-RS, the PDCCH and the triggered CSI-RS may be in the same time slot, i.e., in the same time slot scheduling, or in different time slots, i.e., in the cross-slot scheduling. In the 3GPP protocol, it can be indicated by the CSI-RS trigger offset value that the PDCCH and the CSI-RS triggered by the PDCCH are scheduled simultaneously or in cross slots. If the CSI-RS trigger offset value is 0, it indicates that the PDCCH and the CSI-RS triggered by the PDCCH are in the same time slot, i.e., "simultaneous slot scheduling". If the CSI-RS trigger offset value is greater than 0, the PDCCH and the CSI-RS triggered by the PDCCH are in different time slots, namely cross-slot scheduling. The CSI-RS trigger offset value is closer to the K0 value concept, and in 3GPP standard discussions, it is specified that the network device indicates a value that can be used as both the minimum available value of K0 and the minimum available value of the CSI-RS trigger offset value. The method for updating the minimum available value of K0 according to the embodiment of the present application is also applicable to updating the minimum available value of the CSI-RS trigger offset value.

Taking slot0 occupied by PDCCH, and PDSCH and PUSCH scheduled by PDCCH as an example, as shown in fig. 1, the slot position occupied by PDSCH changes according to the change of K0 value, and the slot position occupied by PUSCH changes according to the change of K2 value. For example, when PDCCH schedules PDSCH0, K0 is 0, PDCCH is in the same time slot as its scheduled PDSCH 0: slot0, when PDCCH schedules PDSCH1, K0 is 1, PDCCH is separated from its scheduled PDSCH1 by 1 slot, and PDSCH1 is located at slot 1; when PDSCH2 is scheduled by PDCCH, K0 is 1, PDCCH is separated from its scheduled PDSCH2 by 1 slot, and PDSCH1 is located at slot 1. When PDCCH schedules PUSCH0, K2 is 2, PDCCH is 2 slots apart from its scheduled PUSCH0, and PUSCH0 is located at slot 2. When PDCCH schedules PUSCH1, K2 is 2, PDCCH is spaced 2 slots apart from its scheduled PUSCH1, and PUSCH0 is located at slot 2.

At present, in the subject of saving power consumption of a terminal, when a network device determines that the terminal saves power consumption, the network device dynamically indicates a minimum available value (or referred to as a minimum available value) to the terminal first, and then indicates a specific value in scheduling information when the network device schedules a data channel of the terminal, where the specific value is not less than the minimum available value under normal conditions, and the terminal determines a time slot position of the data channel scheduled by a PDCCH according to the specific value indicated by the scheduling information, and receives a PDSCH or transmits a PUSCH at the determined time slot position. The technical means for the network device to determine that the terminal needs to save power consumption is not within the scope of the discussion of the embodiments of the present application, and for example, the network device may determine whether the terminal needs to save power consumption by referring to the prior art, for example: the terminal can detect the electric quantity of the terminal, when the electric quantity of the terminal is lower than a certain threshold value, the terminal sends a power consumption saving request to the network equipment, and the network equipment receives the power consumption saving request sent by the terminal and determines that the power consumption is saved for the terminal.

For example, taking a terminal as a mobile phone and a network device as a base station as an example, fig. 2-1 shows a scene schematic diagram of a scheduling manner indicated by the base station to the mobile phone, as shown in fig. 2-1, when the base station determines that the mobile phone saves power and time, the base station sends a power consumption saving signal carrying the minimum available value of K0 to the mobile phone, such as: the minimum available value of K0 is indicated to the handset as 2. Subsequently, when the base station learns that the server pushes the weather forecast to the mobile phone, the base station firstly sends the PDCCH carrying the K0 value to the mobile phone, and when the PDSCH sent to the mobile phone is scheduled through the PDCCH, wherein the K0 value indicated in the scheduling information of the PDCCH is not less than 2, if: the indicated value of K0 may be 2 or 3 or 4, etc. Taking the K0 value indicated by the base station as 2 as an example, next, the base station sends a PDSCH carrying related information of a weather forecast to the mobile phone, the mobile phone receives the PDSCH sent by the base station according to scheduling information in the PDCCH at a position spaced by 2 time slots from the PDCCH, and displays the received related information of the weather forecast (weather of the day now: light rain, 22 degrees, please carry an umbrella.

Similarly, the base station may also indicate the minimum available value of K2 and the value of K2 to the handset in the manner described above. For another example, when the base station indicates that the minimum available value of K2 is 3 to the cell phone, and the base station schedules the cell phone to perform PUSCH transmission, the specific K2 value indicated in the scheduling information is not less than 3, such as: the indicated value of K2 may be 3 or 4, etc.

However, in practical applications, a specific value indicated in the scheduling information may be smaller than the minimum available value, for example: the network device sends a switching instruction to the terminal, the switching instruction indicates to change the minimum available value of the terminal, but the terminal does not receive the switching instruction, namely the terminal fails to detect the switching instruction, and subsequently, the network device configures a specific value according to the changed minimum available value, but the configured specific value is smaller than the minimum available value before the change. In this case, how the terminal handles is not specified in the prior art, but the embodiment of the present application provides a feasible solution for how the terminal handles when the specific value indicated in the scheduling information is smaller than the minimum available value.

The following describes, with reference to the accompanying drawings of the specification, a processing behavior of the terminal in a case where a specific value indicated in the scheduling information is smaller than a minimum available value.

The scheduling switching method provided by the embodiment of the application can be used for a communication system supporting multiple scheduling modes, such as: can be applied to the fourth generation (4)^thgeneration, 4G) system, Long Term Evolution (LTE) system, fifth generation (5th generation, 5G) system, New Radio (NR) system, and any of the vehicle-to-any communication (V2X) systems, and may be applied to other next-generation communication systems, and the like, without limitation. The method provided by the embodiment of the present application is described below by taking the communication system shown in fig. 2 as an example.

Fig. 2 is a schematic diagram of a communication system according to an embodiment of the present application, and as shown in fig. 2, the communication system may include a network device and a plurality of terminals (e.g., terminal 1, terminal 2). The terminal can be located in the coverage area of the network equipment and connected with the network equipment. In the system shown in fig. 2, the terminal may receive the PDCCH transmitted by the network device, and transmit the PUSCH to the network device or receive the PDSCH transmitted by the network device under the instruction of the DCI included in the PDCCH, or receive the CSI-RS transmitted by the network device under the instruction of the DCI included in the PDCCH, or the like.

Specifically, the implementation process may be described with reference to the corresponding embodiment in fig. 4.

For another example, taking K2 as the second parameter and the minimum available value of K2 as the second threshold, the terminal receives, from the network device, indication information indicating a value of the second parameter, and when the value of the second parameter indicated by the indication information is smaller than the second threshold, the terminal updates the second threshold according to the received indication information.

In the embodiment of the present application, the name of the message exchanged between the devices or the name of the parameter in the message, etc. are only an example, and other names may also be used in the specific implementation, which is not limited. For example, the indication information in the following embodiments may also be described as a power saving signal (power saving signal) or the like, without limitation.

The following describes a scheduling handover method provided in the embodiment of the present application with reference to the communication system shown in fig. 2. Among them, each device in the following embodiments may have the components shown in fig. 3.

Fig. 4 is a scheduling switching method provided in an embodiment of the present application, and as shown in fig. 4, the method may include:

step 401: the network equipment sends the first indication information to the terminal.

The network device may be any network device in fig. 2, and the terminal may be any terminal that establishes a Radio Resource Control (RRC) connection in communication with the network device.

The first indication information may be used to indicate a value (value) of a first parameter, where the first parameter is a time slot interval between the PDCCH and the PDSCH scheduled by the PDCCH, for example: the first parameter may be K0 described above. The first indication information may be included in the PDCCH, such as: the first indication information may be included in the scheduling information (e.g., DCI) carried by the PDCCH, or may be carried in a different information element of the PDCCH from the scheduling information, without limitation.

Specifically, the first indication information may include a value of the first parameter, and may also include an index value, where the index value may be an index value in a TDRA table shown in table one, and corresponds to the value of the first parameter, and may also include other identifiers that may indicate the value of the first parameter, which is not limited. For example, taking the first parameter K0 as an example, if the value of K0 is 1, when the network device indicates the value of K0 to the terminal, the first indication information may include 1, and may also include an index value 2 corresponding to 1.

The TDRA table shown in table one may be configured to the terminal by the network device when the terminal establishes RRC connection with the network device. Such as: the network equipment can send RRC configuration information to the terminal, wherein the RRC configuration information comprises a TDRA table; alternatively, the network device may transmit Media Access Control (MAC) layer signaling including the TDRA table to the terminal.

Illustratively, the network device may send the first indication information to the terminal through the Uu port.

Step 402: the terminal receives first indication information sent by the network equipment.

Illustratively, the terminal may receive the first indication information sent by the network device through the Uu port.

Further, the terminal may analyze the received PDCCH including the first indication information, and determine a value of the first parameter according to the first indication information. And comparing the value of the first parameter with a first threshold, if the value of the first parameter is smaller than the first threshold, executing step 403, otherwise, if the value of the first parameter is greater than or equal to the first threshold, receiving, by the terminal, the PDSCH sent by the network device according to the scheduling information in the PDCCH.

The first threshold may be a minimum available value (minimum application value) of the first parameter when the terminal receives the first indication information, or may be described as a minimum available value of the first parameter that is effective (or activated/used) when the terminal receives the first indication information.

Wherein the first threshold value may be indicated to the terminal by the network device.

For example, before step 401, the network device sends the first threshold directly to the terminal.

For another example, before step 401, the network device sends an index value corresponding to the first threshold to the terminal, and after receiving the index value, the terminal determines the first threshold according to the received index value and the first correspondence relationship.

The first corresponding relationship may include a corresponding relationship between the index value and a first threshold, the first corresponding relationship may include one or more first thresholds, the first threshold included in the first corresponding relationship may be referred to as a first threshold selectable value or a candidate value of a minimum available value of the first parameter, and the number of the first thresholds included in the first corresponding relationship is limited.

The first corresponding relationship may be pre-configured to the terminal by the network device, for example: the network device may indicate the first threshold to the terminal through physical layer signaling before the network device indicates the first threshold to the terminal, and subsequently, the network device may select one first threshold from the first corresponding relationship, and indicate an index value corresponding to the selected first threshold to the terminal, so that the terminal determines the first threshold indicated by the network device according to the received index value and the first corresponding relationship.

The first corresponding relationship may be a list-form corresponding relationship or an array-form corresponding relationship, and the like, which is not limited. The embodiment of the present application is described by taking the first correspondence as an example of the correspondence in the form of a list. For example, the following table three shows the first corresponding relationship, and as shown in table three, when the index value is 0, the first threshold value is 0, when the index value is 1, the first threshold value is 1, when the index value is 2, the first threshold value is 3, and the selectable value of the first threshold value is {0, 1, 3 }. If the network device determines that the first threshold of the terminal is 2, the network device may indicate the index value 2 corresponding to the first threshold to the terminal, and after receiving the index value 2, the terminal determines that the first threshold is 3 by using the index value 2 as an index and looking up the table three.

Watch III

Index value	First threshold value
		0	0
1	1
		2	3

Step 403: and if the value of the first parameter is smaller than the first threshold, the terminal updates the first threshold according to the first indication information.

For example, the terminal may update the first threshold in any one of three ways:

the first method is as follows: and the terminal determines the value of the first parameter as a new first threshold value.

For example, if the value of the first parameter indicated to the terminal by the network device is 1, the first threshold is updated to 1.

In the first mode, if there is no association relationship between the first threshold and the second threshold, the second threshold is the minimum available value of the second parameter, and the second parameter is the time slot interval of the PDCCH and the PUSCH scheduled by the PDCCH, the terminal does not update the second threshold, that is, the second threshold when the terminal receives the first indication information is kept unchanged.

If the first threshold and the second threshold have an association relationship, the terminal may not update the second threshold, or may update the second threshold, that is, update the second threshold when the terminal receives the first indication information, so that the original association relationship is stored between the new second threshold and the new first threshold.

Wherein, having an association relationship between the first threshold and the second threshold may include: the first threshold value is the same as the second threshold value and is the same minimum available value; or the first threshold is the same as the second threshold and is the same minimum available value, and the minimum available value corresponds to the index value; or the first threshold value and the second threshold value have an association relation; or the second threshold and the first threshold correspond to the same index value. Before step 401, the network device may indicate a plurality of first threshold values (alternatively referred to as first threshold value selectable values) and a plurality of second threshold values (alternatively referred to as second threshold value selectable values) to the terminal, and the first threshold values and the second threshold values have an association relationship therebetween.

The association relationship between the first threshold and the second threshold may be an association relationship in a list form, or an association relationship in an array form, without limitation. In the embodiment of the present application, the correlation between the first threshold and the second threshold is taken as an example of a tabular correlation.

For example, taking the second threshold and the first threshold corresponding to the same index value as an example, the following table four shows the association relationship between the first threshold and the second threshold, as shown in table four, the association relationship may be regarded as that the second threshold is added to the first correspondence relationship, and the added first threshold and the added second threshold correspond to the same index value, such as: when the index value is 0, the first threshold value is 0, and the second threshold value is 1; when the index value is 1, the first threshold value is 1, and the second threshold value is 2; at index 2, the first threshold is 3 and the second threshold is 4. If the updated first threshold is 1, the second threshold can be updated to 2 by looking up the table four.

Index value	First threshold value	Second threshold value

			2	3	4

For another example, taking the same first threshold value and the same second threshold value as the same minimum available value, and taking the example that the minimum available value corresponds to the index value, table five below shows the association relationship between the first threshold value and the second threshold value, as shown in table five, when the index value is 0, the first threshold value and the second threshold value are 0; when the index value is 1, the first threshold value and the second threshold value are 1; when the index value is 2, the first threshold value and the second threshold value are 3. If the new first threshold is 1, the table lookup indicates that the second threshold may also be updated to 1.

The second method comprises the following steps: the terminal determines the default value of the first parameter as a new first threshold value.

The default value of the first parameter may be a K0 value with a minimum value in the TDRA table shown in table one. Alternatively, the default value of the first parameter is indicated to the terminal by the network device, such as: the network device may send higher layer signaling (e.g., RRC signaling or media access control element (MAC CE)) to the terminal, where the higher layer signaling may be used to indicate a default value of the first parameter.

In the second mode, if the first threshold and the second threshold are not associated, the terminal does not update the second threshold, that is, the second threshold is kept unchanged. If the first threshold and the second threshold have an association relationship, the terminal may not update the second threshold, or may update the second threshold to a default value of the second parameter.

The default value of the second parameter may be a K2 value with a minimum value in the TDRA table shown in table two. Or, the default value of the second parameter is dynamically indicated to the terminal by the network device, such as: the network device may send higher layer signaling to the terminal, which may be used to indicate a default value for the second parameter.

The third method comprises the following steps: and the terminal determines the first threshold optional value with the largest value as a new first threshold from the first threshold optional values which are not larger than the value of the first parameter. Alternatively, it may be described that the first threshold closest to the value of the first parameter, from among the selectable first threshold values that are not greater than the value of the first parameter, is determined as the new first threshold value.

Wherein the first threshold selectable value may include a plurality. The first selectable threshold value may be pre-configured to the terminal by the network device in the first corresponding relationship, or may be separately configured to the terminal by the network device, for example: the network device may configure the first threshold selectable value and an index value (as shown in table three) corresponding to the first threshold selectable value to the terminal, or directly configure the first threshold selectable value {0, 1, 3} to the terminal.

For example, if the value of the first parameter indicated by the first indication information is 3, the terminal may obtain two optional values not greater than 3 from table three: 0 and 1, with 1 as the new first threshold.

In the third mode, if the first threshold and the second threshold have no association relationship, the terminal does not update the second threshold, that is, the second threshold is kept unchanged. If the first threshold and the second threshold have an association relationship, the terminal may not update the second threshold, or may update the second threshold, so that the new second threshold and the new first threshold maintain the original association relationship.

The association relationship between the first threshold and the second threshold, and the process of updating the second threshold by the terminal according to the new first threshold are as described in the first embodiment, and are not repeated.

Based on the method shown in fig. 4, the terminal may update the first threshold according to the value of the first parameter when the value of the first parameter indicated to the terminal by the network device is smaller than the first threshold. Therefore, a feasible scheme is provided for the processing behavior of the terminal under the condition that the value of the first parameter is smaller than the first threshold, and meanwhile, the consistency of the scheduling modes of the terminal and the network equipment is ensured by updating the first threshold.

In the first embodiment of the method shown in fig. 4, before performing step 401, the terminal further needs to start its own function of switching the scheduling scheme. Specifically, the terminal may start its own function of switching scheduling modes by using the following examples:

in one example, when the network device finds that no data is sent to the terminal for a certain period of time, the network device wants to save power consumption for the terminal, the network device sends a start instruction to the terminal, the start instruction is used for instructing the terminal to start a function of switching a scheduling mode, the terminal receives the start instruction sent by the network device, and the function of switching the scheduling mode is started according to the start instruction.

In this example, the network device determines that no data has been sent to the terminal for a period of time by: the network equipment determines that no data is sent to the terminal when detecting that a data buffer serving the terminal is empty; or, when the network device cannot acquire the downlink data of the terminal from the core network within a period of time, it is determined that no data is sent to the terminal within the period of time.

In another example, when the terminal detects that the electric quantity of the terminal is lower than the preset threshold, the terminal sends an energy saving request for requesting the network device to save power consumption for the terminal to the network device, the network device receives the energy saving request sent by the terminal, determines that the power consumption is saved for the terminal, sends a start instruction for instructing the terminal to start a function of switching a scheduling mode to the terminal, and the terminal receives the start instruction sent by the network device and starts the function of switching the scheduling mode according to the start instruction.

The preset threshold value can be set according to needs, and is not limited. When the electric quantity of the terminal is lower than the preset threshold value, the terminal is in a low electric quantity state, and power consumption needs to be saved. In yet another example, the terminal may detect whether the automatic power is lower than a preset threshold through the prior art, without limitation.

Further optionally, after the terminal starts the scheduling mode switching, a response is sent to the network device, where the response is used to indicate that the terminal has started the function of switching the scheduling mode.

In another example, when the terminal detects that there is no service demand, the terminal sends an energy-saving request for requesting the network device to save power consumption for the terminal to the network device, the network device receives the energy-saving request sent by the terminal, determines that the terminal saves power consumption, sends a start instruction for instructing the terminal to start a function of switching a scheduling mode to the terminal, and the terminal receives the start instruction sent by the network device and starts the function of switching the scheduling mode according to the start instruction.

The terminal detecting that no service requirement exists may include: the terminal detects the working state of Applications (APPs) in the terminal, and if all the APPs are in the closed state, the terminal determines that no service is required.

In a second embodiment of the method shown in fig. 4, the method further comprises: and if the value of the first parameter is smaller than the first threshold, the terminal ignores the scheduling information in the PDCCH and does not receive the PDSCH scheduled by the PDCCH according to the PDCCH scheduling information.

For convenience of understanding, the method shown in fig. 4 is described below with reference to the scenarios shown in fig. 5-1 and fig. 5-2 in which the user browses a web page through a mobile phone, where the terminal is a mobile phone, the network device is a base station, the first parameter is K0, and the first threshold is the minimum available value of K0. In the scenario that the user browses the web page through the mobile phone as shown in fig. 5-1, after the base station establishes Radio Resource Control (RRC) connection with the mobile phone, the base station sends a TDRA table to the mobile phone and instructs the mobile phone to start the function of scheduling and switching. When the mobile phone browses hot news, after the base station determines that the hot news is loaded, the base station indicates the minimum available value of K0 to be 3 to the mobile phone, so that the mobile phone is in a cross-time-slot scheduling working mode. After the mobile phone receives that the minimum available value of K0 indicated by the base station is 3, the base station learns that the server pushes weather forecast to the mobile phone, the base station first sends PDCCH1 carrying the value K0 equal to 3 to the mobile phone, schedules PDSCH1 sent to the mobile phone through PDCCH1, the mobile phone receives PDSCH1 sent by the base station according to the PDCCH1 at a position 3 time slots away from PDCCH1 according to the scheduling information in PDCCH1, and displays the received weather forecast related information (the current day weather: light rain, 22 degrees, please carry an umbrella.

Fig. 5-2 is another view of the scenario that the user browses the web page again through the mobile phone after fig. 5-1, and in the scenario that the user browses the web page through the mobile phone shown in fig. 5-2, when the mobile phone browses the fallen leaf picture, the base station indicates to the mobile phone that the minimum available value of K0 is 0, so that the mobile phone is in a slotted scheduling mode, but the mobile phone does not receive an indication of the base station. Subsequently, when the base station learns that the server pushes the today's headline to the cell phone, the base station sends PDCCH2 carrying the K0 with the value of 1 to the cell phone according to the minimum available value 0 of K0 indicated by the base station, schedules PDSCH2 carrying the today's headline to the cell phone through PDCCH2, and after the cell phone receives PDCCH2, finds that the K0 value 1 is smaller than the original minimum available value 3 of K0, the minimum available value of K0 is updated by using the method described in the embodiment of the present application, and meanwhile, the scheduling information in PDCCH2 is ignored, that is, PDSCH2 scheduled by PDCCH2 is not received.

With reference to fig. 5-3, the following describes an execution process between the mobile phone and the base station in the scenario shown in fig. 5-1 and 5-2, by taking the hot news browsing by the mobile phone as an example of browsing the first webpage by the mobile phone, and the fallen leaf picture browsing by the mobile phone as an example of browsing the second webpage by the mobile phone:

fig. 5-3 is a scheduling switching method provided in an embodiment of the present application, and as shown in fig. 5-3, the method may include:

step 501: the mobile phone establishes RRC connection with the base station.

The process of establishing the RRC connection between the mobile phone and the base station may refer to the prior art and is not described herein.

Step 502: and the base station configures a TDRA table to the mobile phone.

The TDRA table may be as shown in table one, which is not repeated herein.

Illustratively, the base station may send RRC configuration information to the handset, the RRC configuration information including a TDRA table; alternatively, the base station may send MAC layer signaling to the handset, the MAC signaling including a TDRA table.

Step 503: and the mobile phone receives the TDRA table sent by the base station and stores the TDRA table.

Because the TDRA table includes the case that K0 is 0 and the case that the value of K0 is greater than 0, the terminal cannot predict what the specific value of K0 is indicated when the network device schedules data according to the TDRA table, and at this time, the terminal may set its scheduling mode to "slotted simultaneous scheduling", that is, cache data in advance.

Step 504: the mobile phone starts the function of switching the scheduling mode.

Step 504 may be described with reference to the first embodiment of the method shown in fig. 4, such as: the base station directly indicates the mobile phone to start the function of switching the scheduling mode, or when the mobile phone detects that the electric quantity is low or no service is transmitted, the base station sends an energy-saving request for requesting the base station to save power consumption of the mobile phone, the base station receives the energy-saving request sent by the mobile phone, determines that the mobile phone saves power consumption, sends a starting instruction for indicating the mobile phone to start the function of switching the scheduling mode to the mobile phone, and the mobile phone receives the starting instruction sent by the base station and starts the function of switching the scheduling mode according to the starting instruction.

Step 505: the mobile phone receives a first browsing request sent by a user and sends the first browsing request to the base station.

The first browsing request may be used to request browsing of the first webpage. Illustratively, a user may click an icon or a control on a User Interface (UI) interface of a mobile phone to trigger a first browsing request; alternatively, the user inputs a Uniform Resource Locator (URL) (or a web page address) of the first web page in an input box of the browser, and the first browsing request is triggered.

Step 506: the base station receives a first browsing request sent by the mobile phone, sends the first browsing request to the server, and indicates the minimum available value of K0 to the mobile phone to be 0 according to the first browsing request.

In step 506, when the user clicks or refreshes the first webpage, data interaction may occur between the mobile phone and the base station, and in order to reduce data transmission delay, increase webpage loading speed, and increase user experience, the minimum available value of K0 indicated to the mobile phone by the base station is 0, that is, the same time slot scheduling is used.

In one example, the base station indicating the minimum available value of K0 to the handset may include: and the base station sends indication information to the mobile phone, wherein the indication information comprises the minimum available value of K0, and after receiving the indication information, the mobile phone directly determines the minimum available value of K0 according to the indication information.

In yet another example, the base station indicating to the handset the minimum available value of K0 may include: and the base station sends an index value to the mobile phone, the index value corresponds to the K0 value, and after receiving the index value, the mobile phone queries the TDRA table according to the index value and determines the minimum available value of K0 as a value corresponding to the index value.

Step 507: the terminal obtains the minimum available value of K0 indicated by the base station, and determines to execute the slotted scheduling according to the minimum available value of K0 indicated by the base station.

Step 508: the base station sends a first switching indication to the handset, the first switching indication indicating a new minimum available value of K0, the new minimum available value of K0 being greater than 0, such as: the new minimum available value of K0 is 3.

Illustratively, after the first webpage is loaded, data interaction between the mobile phone and the base station cannot occur, and at this time, the power consumption of the terminal can be reduced by using cross-time-slot scheduling, so that the purpose of saving energy of the terminal is achieved. In order to enable the mobile phone to receive the PDSCH by using the scheduling method of cross-slot scheduling, the base station sends a first handover indication to the terminal, where the first handover indication indicates a larger (or greater than 0) minimum available value of K0, for example, the minimum available value of K0 is 3, and after receiving the first handover indication, the mobile phone receives the PDSCH sent by the base station at least in a slot that is 3 slots apart from the PDCCH, that is, the terminal switches from simultaneous slot scheduling to cross-slot scheduling.

In one possible design, the first switch indication includes a new minimum available value of K0.

In yet another possible design, the first switch indication includes an index value that corresponds to a minimum available value of K0.

Step 509: and the mobile phone receives the first switching instruction and determines to execute cross-time-slot scheduling according to the first switching instruction.

In one possible design, the first switch indication includes a new minimum available value of K0, and the handset determines to perform cross-slot scheduling based on the new minimum available value of K0.

In yet another possible design, the first switching indication includes an index value corresponding to the minimum available value of K0, and the handset determines that the minimum available value of K0 is greater than 0 according to the index value and the first corresponding relationship, and performs cross-slot scheduling.

The first corresponding relationship is as described in the embodiment corresponding to fig. 4, and is not repeated.

Further, the handset may also save the minimum available value of K0 indicated by the first switch indication.

Step 510: the base station determines to transmit a PDSCH1 to the terminal, and before transmitting a PDSCH1, the base station transmits a PDCCH1 for scheduling a PDSCH1 to the terminal, wherein the PDCCH1 includes first indication information, and the first indication information is used for indicating a K0 value, such as: the indication K0 ═ 3.

In one example, the first indication may include a value of K0.

In yet another example, the first indication information includes an index value corresponding to a value of K0 included in the TDRA table.

Step 511: the terminal receives PDCCH1, determines that the value of K0 is not less than the minimum available value of new K0 acquired in step 508 according to the first indication information included in PDCCH1, and receives PDSCH1 in a slot that is spaced from PDCCH1 by K slots, where K is equal to the value of K0.

In one example, when the first indication information includes a value of K0, the handset directly determines a value of K0 from the first indication information. In another example, when the first indication information includes an index value, the mobile phone queries the TDRA table according to the index value, and takes a value corresponding to the index value in the TDRA table as a value K0.

Step 512: and the mobile phone receives a second browsing request sent by the user and sends the second browsing request to the base station.

Wherein the second browsing request may be for requesting browsing of a second web page. The second web page is different from the first web page.

Specifically, the execution process of step 511 can refer to that described in step 505, and is not described in detail.

Step 513: and the base station receives a second browsing request sent by the mobile phone, sends the second browsing request to the server, and sends a second switching instruction to the mobile phone according to the second browsing request, wherein the second switching instruction is used for instructing the mobile phone to switch to the same-time-slot scheduling.

In step 512, when the user clicks on or refreshes the second webpage, data interaction may occur between the mobile phone and the base station, and in order to reduce data transmission delay, increase webpage loading speed, and increase user experience, the minimum available value of K0 indicated to the mobile phone by the base station is 0, that is, the same time slot scheduling is used.

For example, the second switching indication may include a new minimum available value of K0, the new minimum available value of K0 being 0.

Step 514: the handset does not receive the second switching indication, and still performs cross-slot scheduling with the minimum available value of K0 indicated by the first switching indication and the value of K0 indicated by the first indication information, and at this time, the base station considers that the minimum available value of K0 of the handset is 0.

Step 515: the base station determines to transmit a PDSCH2 to the terminal, and before transmitting a PDSCH2, the base station transmits a PDCCH2 for scheduling a PDSCH2 to the terminal, wherein the PDCCH2 includes first indication information, and the first indication information is used for indicating a K0 value, such as: the indication K0 is 1.

Step 515 may refer to step 509, and is not described again.

Step 516: the mobile phone receives and demodulates PDCCH2, determines that the value of K0 is 1 and is less than the minimum available value 3 of K0 according to the first indication information included in PDCCH2, and updates the minimum available value of K0.

When the value of K0 is less than the minimum available value of K0, indicating that the base station does not agree with the minimum available value of K0 understood by the cell phone, the cell phone ignores the scheduling information in PDCCH2 and does not receive PDSCH2 transmitted by the base station, i.e., does not receive PDSCH2 on a slot spaced 1 slot after PDCCH2 from PDCCH2 according to the first indication information.

For example, in this case, the mobile phone determines the speed of demodulating PDCCH2 according to the "minimum available value 3 of K0 indicated by the first handover indication" (or the minimum available value of K0 understood by the mobile phone itself), so that when the mobile phone decodes PDCCH2, the time for transmitting PDSCH2 is already passed, PDSCH2 is not received, the terminal ignores the scheduling, and the scheduling fails.

Subsequently, the handset updates the "minimum available value of K0" according to the method provided by the application, so that the adjusted minimum available value of K0 is the same as the minimum available value of K0 understood by the base station, and when the base station reschedules the same data to the handset, the handset already adjusts the "minimum available value of K0" stored in the handset according to the method provided by the application, and can successfully receive the retransmitted data.

Specifically, the handset may update the minimum available value of K0 in any one of the three manners. Such as: and updating the minimum available value of K0 to 1, or updating the minimum value of K0 to a default value of 0, or acquiring a first threshold {0, 1} which is not more than 1 from the third table, and determining the maximum value of 1 as the new minimum available value of K0.

Further, if the minimum available value of K2 is not related to the minimum available value of K0, the handset does not update the minimum available value of K2, i.e. the minimum available value of K2 is kept unchanged.

If there is an association between the minimum available value of K2 and the minimum available value of K0, the handset does not update the minimum available value of K2, or correspondingly updates the minimum available value of K2. For example, assuming that there is an association between the minimum available value of K2 and the minimum available value of K0 as shown in the above table four, the minimum available value of K2 is updated to 2 or the minimum value of K2 is updated to the default value of 0 according to table four.

Based on the method shown in fig. 5-3, when the value K0 indicated in the scheduling information received by the handset is smaller than the minimum available value of K0 currently in effect, the minimum available value of K0 may be updated to ensure consistency of the scheduling modes of the handset and the base station.

The methods shown in fig. 4 and 5-3 are described for the method that the terminal updates the minimum available value of K0 when the value of K0 received by the terminal is smaller than the minimum available value of K0 in the downlink scheduling scenario. In another method, an embodiment of the present application further provides a method for updating a minimum available value of K2 when a value of K2 received by a terminal is less than the minimum available value of K2 in an uplink scheduling scenario. Specifically, the method can refer to fig. 6:

fig. 6 is a scheduling switching method provided in an embodiment of the present application, and as shown in fig. 6, the method may include:

step 601: and the network equipment sends the second indication information to the terminal.

The network device may be any network device in fig. 2, and the terminal may be any terminal that establishes an RRC connection in communication with the network device.

The second indication information may be used to indicate a value (value) of a second parameter, where the second parameter is a time slot interval between the PDCCH and a PUSCH scheduled by the PDCCH, for example: the second parameter may be K2 described above. The second indication information may be included in the PDCCH, such as: the second indication information may be included in the scheduling information (e.g., DCI) carried by the PDCCH, or may be carried in a different information element of the PDCCH from the scheduling information, without limitation.

Specifically, the second indication information may include a value of the second parameter, or may include an index value, where the index value may be an index value in a TDRA table shown in table two, and corresponds to the value of the second parameter, and may include other identifiers that may indicate the value of the second parameter, which is not limited. For example, taking the second parameter K2 as an example, if the value of K2 is 2, when the network device indicates the value of K2 to the terminal, the second indication information may include 2, and may also include an index value 1 corresponding to 1.

The TDRA table shown in table two may be configured to the terminal by the network device when the terminal establishes RRC connection with the network device. Such as: the network equipment can send RRC configuration information to the terminal, wherein the RRC configuration information comprises a TDRA table; alternatively, the network device may send MAC layer signaling to the terminal, the MAC signaling including the TDRA table.

Illustratively, the network device may send the second indication information to the terminal through the Uu port.

Step 602: and the terminal receives second indication information sent by the network equipment.

Illustratively, the terminal may receive the second indication information sent by the network device through the Uu port.

Further, the terminal may analyze the received PDCCH including the second indication information, and determine a value of the second parameter according to the second indication information. And comparing the value of the second parameter with a second threshold, if the value of the second parameter is smaller than the second threshold, executing the step 603, otherwise, if the value of the second parameter is larger than or equal to the second threshold, receiving, by the terminal, the PUSCH transmitted by the network device according to the scheduling information in the PDCCH.

The second threshold may be a minimum available value (minimum application value) of the second parameter when the terminal receives the second indication information, or may be described as a minimum available value of the second parameter that is effective (or activated/used) when the terminal receives the second indication information.

Wherein the second threshold may be indicated to the terminal by the network device.

For example, before step 601, the network device sends the second threshold directly to the terminal.

For another example, before step 601, the network device sends an index value corresponding to the second threshold to the terminal, and after receiving the index value, the terminal determines the second threshold according to the received index value and the second correspondence.

The second correspondence may include a correspondence between the index value and a second threshold, the second correspondence may include one or more second thresholds, the second threshold included in the second correspondence may be referred to as a second threshold selectable value or a candidate value of a minimum available value of the second parameter, and the number of the second thresholds included in the second correspondence is limited.

The second correspondence may be configured in advance to the terminal by the network device, for example: the network device may indicate the second threshold to the terminal through a physical layer signaling before the network device indicates the second threshold to the terminal, and subsequently, the network device may select one second threshold from the second corresponding relationship, and indicate the index value corresponding to the selected second threshold to the terminal, so that the terminal determines the second threshold indicated by the network device according to the received index value and the second corresponding relationship.

The second corresponding relationship may be a corresponding relationship in a list form or a corresponding relationship in an array form, and the like, which is not limited. The embodiment of the present application is described by taking the second correspondence as an example of the correspondence in the form of a list. For example, the following table six shows the second corresponding relationship, and as shown in table six, when the index value is 0, the second threshold value is 0, when the index value is 1, the second threshold value is 1, when the index value is 2, the second threshold value is 3, and the selectable value of the second threshold value is {0, 1, 3 }. If the network device determines that the second threshold of the terminal is 2, the network device may indicate the index value 2 corresponding to the second threshold to the terminal, and after receiving the index value 2, the terminal determines that the second threshold is 3 by using the index value 2 as an index and looking up the table six.

Step 603: and if the value of the second parameter is smaller than the second threshold, the terminal updates the second threshold according to the second indication information.

For example, the terminal may update the second threshold in any one of the following three ways:

the first method is as follows: and the terminal determines the value of the second parameter as a new second threshold value.

For example, if the value of the second parameter indicated to the terminal by the network device is 1, the second threshold is updated to 1.

In the first mode, if there is no association between the second threshold and the first threshold, and the first threshold is as described above, the terminal does not update the first threshold, that is, the first threshold when the terminal receives the second indication information is kept unchanged.

If the second threshold has an association relationship with the first threshold, the terminal may not update the first threshold, or may update the first threshold, that is, update the first threshold when the terminal receives the second indication information, so that the original association relationship is stored between the new second threshold and the new first threshold.

The association relationship between the second threshold and the first threshold may be as described in the first embodiment in fig. 4, which is not repeated herein.

For example, taking table four as an example, if the updated second threshold is 4, the table four can be found by looking up the table four, and the first threshold is updated to 3. For another example, taking table five as an example, if the new second threshold is 3, table five may be looked up to find that the second threshold may also be updated to 3.

The second method comprises the following steps: the terminal determines the default value of the second parameter as a new second threshold value.

The default value of the second parameter may be the smallest K2 value in the second TDRA table shown in table two. Alternatively, the default value of the second parameter is indicated to the terminal by the network device, such as: the network device may send higher layer signaling to the terminal, which may be used to indicate a default value for the second parameter.

In the second mode, if the second threshold is not associated with the first threshold, the terminal does not update the first threshold, that is, the second threshold is kept unchanged. If the second threshold has an association relationship with the first threshold, the terminal may not update the first threshold, or may update the first threshold to a default value of the first parameter, such as: is updated to 0.

The default value of the first parameter may be a K0 value with a minimum value in the TDRA table shown in table one. Or, the default value of the second parameter is dynamically indicated to the terminal by the network device, such as: the network device may send higher layer signaling to the terminal, which may be used to indicate a default value for the second parameter.

The third method comprises the following steps: and the terminal determines the second threshold value with the maximum value as a new second threshold value from the second threshold value optional values which are not larger than the value of the second parameter. Alternatively, it may be described that a second threshold value closest to the value of the second parameter, from among selectable values of the second threshold value that are not greater than the value of the second parameter, is determined as a new second threshold value.

Wherein the second threshold selectable value may comprise a plurality. The second threshold selectable value may be pre-configured to the terminal by the network device in the second corresponding relationship, or may be separately configured to the terminal by the network device, for example: the network device may configure the second threshold selectable value and an index value (as shown in table six) corresponding to the second threshold selectable value to the terminal, or directly configure the second threshold selectable value {1, 2, 4} to the terminal.

For example, if the value of the second parameter indicated by the second indication information is 3, the terminal may obtain two optional values not greater than 3 from table six: 1 and 2, with 2 as the new second threshold.

In the third mode, if the second threshold is not associated with the first threshold, the terminal does not update the first threshold, that is, the second threshold is kept unchanged. If the second threshold and the first threshold have an association relationship, the terminal may not update the first threshold, or may update the first threshold, so that the new second threshold and the new first threshold maintain the original association relationship.

The association relationship between the second threshold and the first threshold, and the process of updating the first threshold by the terminal according to the new second threshold are as described in the first embodiment, and are not repeated here.

Based on the method shown in fig. 6, the terminal may update the second threshold according to the value of the second parameter when the value of the second parameter indicated to the terminal by the network device is smaller than the second threshold. Therefore, a feasible scheme is provided for the processing behavior of the terminal under the condition that the value of the second parameter is smaller than the second threshold, and meanwhile, the consistency of the scheduling modes of the terminal and the network equipment is ensured by updating the second threshold.

In the first embodiment of the method shown in fig. 6, before performing step 601, the terminal further needs to start its own function of switching the scheduling scheme. Specifically, the process of the terminal starting the function of switching the scheduling manner of the terminal itself can be described with reference to the first embodiment of fig. 4, and is not described in detail.

In a second embodiment of the method shown in fig. 6, the method further comprises: and if the value of the second parameter is smaller than a second threshold value, the terminal ignores the scheduling information in the PDCCH and does not send the PUSCH to the network equipment according to the PDCCH scheduling information.

For convenience of understanding, the method shown in fig. 6 is described below with reference to the scenario shown in fig. 7-1 in which the user browses a web page through a mobile phone, taking the terminal as a mobile phone, the network device as a base station, the second parameter as K2, and the second threshold as the minimum available value of K2. In the scenario shown in fig. 7-1, when the user browses the web page through the mobile phone, after the base station establishes RRC connection with the mobile phone, the base station sends a TDRA table to the mobile phone and instructs the mobile phone to start the scheduling switching function. When the mobile phone browses hot news, the base station indicates the minimum available value of K2 to the mobile phone to be 5, so that the mobile phone is in a cross-time-slot scheduling working mode. Subsequently, when the user plays the game of subway cool through the cell phone, the base station indicates to the cell phone that the minimum available value of K2 is 2, but the cell phone does not receive an indication of the base station. Subsequently, when the base station knows that the PUSCH is transmitted by the mobile phone, the base station transmits a PDCCH carrying the value K2 of 2 to the mobile phone according to the minimum available value 2 of K2 indicated by the base station, schedules the PUSCH reported by the mobile phone through the PDCCH, and after the mobile phone receives the PDCCH, finds that the value K2 of 2 is smaller than the original minimum available value 5 of K2, updates the minimum available value of K2 by using the method described in the embodiment of the present application, and ignores scheduling information in the PDCCH and does not transmit the PUSCH.

The following describes an implementation process between the mobile phone and the base station in the scenario shown in fig. 7-1 with reference to fig. 7-2:

fig. 7-2 is a scheduling switching method provided in an embodiment of the present application, and as shown in fig. 7-2, the method may include:

step 701: the mobile phone establishes RRC connection with the base station.

Step 702: and the base station configures a TDRA table to the mobile phone.

The TDRA table can be shown in table two, which is not repeated.

Step 703: and the mobile phone receives the TDRA table sent by the base station and stores the TDRA table.

Because the TDRA table may include a case where K2 is 1 and a plurality of cases where the value of K2 is greater than 1, the terminal cannot predict what the specific value of K2 is indicated when the base station schedules uplink data according to the TDRA table, and at this time, the terminal may set the value of K2 to the minimum value in the TDRA table, such as: when receiving the scheduling information, the mobile phone completes the work of scheduling information demodulation, scheduling information analysis, uplink data preparation and the like in one time slot, and sends the uplink data out in the next time slot of the scheduling information, wherein K2 is 1.

Step 704: the mobile phone starts the function of switching the scheduling mode.

Step 704 may be described with reference to the first embodiment of the method shown in fig. 4, and is not repeated herein.

Step 705: when the user browses the web page through the handset, the base station indicates to the handset a larger minimum available value of K2, for example 5.

Specifically, the process may be described with reference to fig. 5 to 3, where the mobile phone receives a browsing request sent by a user, and sends a first browsing request to the base station. The base station receives the browsing request sent by the mobile phone, sends the browsing request to the server, and indicates the minimum available value of K2 to the mobile phone as 5 according to the browsing request.

Step 706: the terminal receives the minimum available value of K2 indicated by the base station, and adjusts the minimum available value of K2 from 1 to 5 according to the minimum available value of K2 indicated by the base station.

Further, after receiving that the minimum available value of K2 indicated by the base station is 5, the terminal adjusts its scheduling mode, for example: the processing speed of the processor for performing operations such as scheduling information demodulation, scheduling information analysis, uplink data preparation and the like can be reduced.

Step 707: when the user plays an online game using the handset, the base station indicates the minimum available value of K2 to the handset as 2 so that the terminal accelerates the processing speed of the processor.

Step 708: the minimum available value of K2 indicated by the cell phone not receiving the base station is 2, and the minimum available value of K2 is still considered to be 5.

Step 709: the base station determines that the terminal sends the PUSCH, and before sending the PUSCH, the base station sends a PDCCH for scheduling the PUSCH to the terminal, wherein the PDCCH comprises second indication information which is used for indicating a K2 value, such as: the indication K2 is 2.

Step 710: the mobile phone receives and demodulates the PDCCH, determines that the value of K2 is 2 and is smaller than the minimum available value 5 of K2 stored in the mobile phone according to the second indication information included in the second PDCCH, and updates the minimum available value of K2.

Further, when the value of K2 is less than the minimum available value of K2, it indicates that the base station does not agree with the minimum available value of K2 that the handset understands, and the handset ignores the scheduling information in the PDCCH and does not transmit PUSCH to the base station.

Specifically, the handset may update the minimum available value of K2 in any one of the three ways shown in fig. 6. Such as: and updating the minimum available value of K2 to 2, or updating the minimum value of K2 to a default value of 1, or acquiring a second threshold {1, 2} which is not more than 2 from the third table, and determining the maximum value of 2 as the new minimum available value of K2.

Further, if the minimum available value of K2 is not related to the minimum available value of K0, the handset does not update the minimum available value of K0, i.e. the minimum available value of K0 is kept unchanged.

If there is an association between the minimum available value of K2 and the minimum available value of K0, the handset does not update the minimum available value of K0, or correspondingly updates the minimum available value of K0. For example, assuming that there is an association between the minimum available value of K2 and the minimum available value of K2 as shown in the above table four, the minimum available value of K0 is updated to 1 or the minimum value of K0 is updated to the default value of 0 according to table four.

Based on the method shown in fig. 7-2, when the value K2 indicated in the scheduling information received by the handset is smaller than the minimum available value of K2 currently in effect, the minimum available value of K2 may be updated to ensure consistency of the scheduling modes of the handset and the base station.

In practical application, the network device may configure the function of "starting a switching scheduling mode" for the terminal, configure a plurality of minimum available time slot intervals for the terminal, enable the terminal to have the function of switching the scheduling mode, switch its own scheduling mode according to the time slot interval indicated by the network device when the terminal starts the function of switching the scheduling mode, and schedule (receive or transmit) data by using the time slot interval indicated by the network device. However, before the terminal does not receive the indication information indicating the specific timeslot interval sent by the network device, how the terminal determines its own scheduling mode is not specified in the prior art. The following describes, by using the method shown in fig. 8, a processing behavior before the terminal does not receive indication information sent by the network device to indicate a specific timeslot interval:

fig. 8 is a further scheduling switching method provided in the embodiment of the present application, and as shown in fig. 8, the scheduling switching method may include:

step 801: the network equipment sends the first configuration information to the terminal.

The network device may be the network device in fig. 2, and the terminal may be any terminal in fig. 2 that establishes an RRC connection with the network device.

The first configuration information is used for indicating the terminal to start a function of switching the scheduling mode. The first configuration information may be referred to as a power saving signal (power saving signal).

For example, the network device may determine to save power consumption for the terminal, and send the first configuration information to the terminal after determining to save power consumption for the terminal. The process of determining, by the network device, to save power consumption for the terminal may be described with reference to the first embodiment of the method shown in fig. 4, and is not described again.

Illustratively, the network device may send the first configuration information to the terminal through the Uu port.

Step 802: the terminal receives first configuration information sent by the network equipment.

Illustratively, the terminal may receive the first configuration information sent by the network device through the Uu port.

Further, the terminal starts the function of switching the scheduling mode according to the first configuration information.

Step 803: and the network equipment sends the second configuration information to the terminal.

Wherein the second configuration information may be used to indicate a minimum available slot interval of the terminal. The second configuration information may be used to indicate a plurality of minimum available slot intervals for the terminal. The minimum available timeslot interval is a legal value (or a valid value) of the minimum available timeslot interval that the network device can indicate to the terminal, and the duration of each minimum available timeslot interval is greater than or equal to 0, that is, each minimum available timeslot interval may be 0 or greater than 0; alternatively, it can be described that each minimum available slot interval is an integer multiple of a time unit, the multiple is greater than or equal to 0, and the time unit can be a slot (slot) or a subframe (subframe) or other time unit with a granularity of division, which is not limited.

The minimum available time slot interval may be a minimum available time slot interval between the PDCCH and a data channel scheduled by the PDCCH, and the minimum available time slot interval may include at least one of an uplink minimum available time slot interval and a downlink minimum available time slot interval. The network device may configure one or more downlink minimum available slot intervals for each downlink BWP, and the network device may configure one or more uplink minimum available slot intervals for each uplink BWP.

When the data channel scheduled by the PDCCH is PDSCH, the minimum available slot interval includes a downlink minimum available slot interval, such as: the minimum available slot interval is the minimum available value of K0. When the data channel scheduled by the PDCCH is PUSCH, the minimum available slot interval may include an uplink minimum available slot interval, such as: the minimum available slot interval may be the minimum available value of K2. When the data channels scheduled by the PDCCH are PDSCH and PUSCH, the minimum available slot interval may include a downlink minimum available slot interval and an uplink minimum available slot interval, such as: the second configuration information may be used to indicate a minimum available value of K0 and a minimum available value of K2.

For example, taking the minimum available value of the minimum available slot interval of K0 as an example, the second configuration information may indicate the minimum available value of one or more K0, such as: a minimum available value of K0 greater than 0 may be indicated, a plurality of minimum available values of K0 greater than 0 may be indicated, a minimum available value of K0 equal to 0 and a minimum available value of K0 greater than 0 may be indicated, and so on.

For another example, taking the minimum available value of the minimum available slot interval of K2 as an example, the second configuration information may indicate the minimum available value of one or more K2, such as: a minimum available value of K2 greater than 0 may be indicated, a plurality of minimum available values of K2 greater than 0 may be indicated, a minimum available value of K2 equal to 0 and a minimum available value of K2 greater than 0 may be indicated, and so on.

The second configuration information may include a minimum available slot interval, and further, may further include other information such as an index value corresponding to the minimum available slot interval. For example, the second configuration information may include a TDRA table as shown in table one or table two, or a list as shown in table seven, table eight, and table nine.

Illustratively, the network device may send physical layer signaling (e.g., MAC CE) to the terminal, the physical layer signaling including the second configuration information.

Step 804: and the terminal receives second configuration information sent by the network equipment.

For example, the terminal may receive physical layer signaling sent by the network device, and obtain the second configuration information from the physical layer signaling. Wherein the physical layer signaling comprises second configuration information.

It should be noted that, the present application does not limit the execution sequence of step 803 to step 804, and step 803 to step 804 may precede step 801, such as: step 803 to step 804 are executed first, and then step 801 to step 802 are executed; alternatively, it may be performed in the order shown in fig. 8; step 801 and step 803 may be executed at the same time, and then step 802 and step 804 may be executed at the same time, for example: the steps 801 to 804 can be replaced by: the network device sends the first configuration information and the second configuration information to the terminal, and the terminal receives the first configuration information and the second configuration information.

Step 805: and the terminal determines the target time slot interval of the terminal according to the first configuration information and the second configuration information.

The target timeslot interval may be a minimum available timeslot interval used after the terminal receives the first configuration information and the second configuration information and before receiving indication information used for indicating the timeslot interval and sent by the network device.

Specifically, the terminal may determine the target slot interval of the terminal by any one of the methods (1) to (4):

in the method (1), the second configuration information includes a TDRA table, and the TDRA table includes a plurality of time slot intervals; the terminal determines a target time slot interval of the terminal according to the first configuration information and the second configuration information, and the method comprises the following steps: the terminal determines the minimum available slot interval in the TDRA table as the target slot interval.

For example, taking the minimum available value with the minimum available timeslot interval of K0, the TDRA table is the TDRA table shown in table one, and the TDRA table includes both a K0 value equal to 0 and a K0 value greater than 0, and the terminal cannot predict the specific value of K0 indicated when the network device schedules data according to the TDRA table. At this time, the terminal determines the minimum value of K0 in the TDRA table as the target timeslot interval of the terminal, such as: 0 is determined as the minimum available value of K0, default to co-slotted scheduling.

For another example, the minimum available timeslot interval is the minimum available value of K2, and the TDRA table is a TDRA table shown in table two, where the TDRA table includes a plurality of K2 values greater than 0, and the terminal cannot predict the specific value of K2 indicated when the network device schedules data according to the TDRA table. At this time, the terminal determines the minimum value of K2 in the TDRA table as the target timeslot interval of the terminal, such as: a 1 is determined as the minimum available value of K2.

In the method (1), the second configuration information needs to be transmitted to the terminal before step 801. Such as: in the scenario of the method (1), the steps 803 to 804 are performed first, and then the steps 801 to 802 are performed.

The mode (2) and the second configuration information only include one minimum available slot interval; the terminal determines a target time slot interval of the terminal according to the first configuration information and the second configuration information, and the method comprises the following steps: and the terminal determines the minimum available time slot interval included in the configuration information as a target time slot interval.

In the method (2), one minimum available timeslot interval included in the second configuration information may be a minimum available timeslot interval equal to 0, or a minimum available timeslot interval greater than 0, which is not limited.

Wherein, when the minimum available slot interval is the minimum available value of K0, the target slot interval is the target K0 value. When the minimum available slot interval is the minimum available value of K2, the target slot interval is the target K2 value.

In one example, the second configuration may include only a minimum available slot spacing greater than 0. For example, the second configuration information includes a minimum available value {2} of K0, and the terminal determines 2 as the target slot interval of the terminal.

Further, in this example, the minimum available slot interval indicated by the second configuration information may further include a minimum available slot interval equal to 0. The minimum available slot interval equal to 0 may be explicitly included in the second configuration information, such as: the second configuration information may include {0, 2}, or may be implicitly indicated, such as: the minimum available slot interval indicated by the default second configuration information includes a minimum available value equal to 0 in the TDRA table.

In yet another example, the second configuration information may include a minimum available slot interval greater than 0 and an index value corresponding to the minimum available slot interval greater than 0. For example, taking the minimum available value of the minimum available slot interval K0 as an example, the second configuration information includes { index value 1, minimum available value 2 of K0 }, or alternatively, includes a list as shown in table seven below.

Further, in this example, the minimum available slot interval indicated by the second configuration information may further include a minimum available slot interval equal to 0 and an index value corresponding to the minimum available slot interval equal to 0. The minimum available slot interval equal to 0 may be explicitly included in the second configuration information or may be indicated by implicit means, such as: the minimum available slot interval indicated by the default second configuration information includes a minimum available value equal to 0 in the TDRA table.

Taking as an example that the minimum available slot interval equal to 0 may be explicitly included in the second configuration information, the minimum available slot interval being the minimum available value of K0, table seven below shows an implementation form of the second configuration information, such as table seven, the second configuration information includes a minimum available value of K0 greater than 0 and a minimum available value of K0 equal to 0. In this case, once the network device configures the terminal with the list shown in table seven, the terminal uses a value equal to 2 as the target slot interval for the terminal.

Similarly, the method for indicating the minimum available value of K2 by the second configuration information and the method for determining the target value of K2 by the terminal according to the first configuration information and the second configuration information can be referred to in the method (2), and are not repeated.

The method (3) and the second configuration information comprise a plurality of minimum available slot intervals; the terminal determines a target time slot interval of the terminal according to the first configuration information and the second configuration information, and the method comprises the following steps: the terminal determines the minimum available time slot interval with the largest value or the smallest value as a target time slot interval from the plurality of minimum available time slot intervals; alternatively, the plurality of minimum available slot intervals include a first used value (first used value), and the terminal determines the first used value as the target slot interval.

The first-used value may be configured to the terminal in advance by the network device, and may also be referred to as a default value (default value), or the first-used value may be the largest index value among the plurality of minimum available slot intervals, or the first-used value may be the smallest index value among the plurality of minimum available slot intervals.

In the method (3), the plurality of minimum available slot intervals included in the second configuration information may be a plurality of minimum available slot intervals greater than 0, or may be a set of a minimum available slot interval equal to 0 and a minimum available slot interval greater than 0, which is not limited.

In one example, the second configuration information may include a number of minimum available slot intervals greater than 0. Further, in this example, the minimum available slot interval indicated by the second configuration information may further include a minimum available slot interval equal to 0. The minimum available slot interval equal to 0 may be explicitly included in the second configuration information, such as: the second configuration information may include {0, 2, 3}, or may be indicated by implicit means, such as: the minimum available slot interval indicated by the default second configuration information includes a minimum available value equal to 0 in the TDRA table.

In yet another example, the second configuration information may include a minimum available slot interval greater than 0 and an index value corresponding to the minimum available slot interval greater than 0. For example, taking the minimum available value of the minimum available slot interval K0 as an example, the second configuration information includes { index value 1, minimum available value 1 of K0 }, { index value 2, minimum available value 2 of K0 }, { index value 3, minimum available value 3 of K0 }, or includes a list as shown in table eight and table nine below.

Further, in yet another example, the minimum available slot interval indicated by the second configuration information may further include a minimum available slot interval equal to 0 and an index value corresponding to the minimum available slot interval equal to 0. The minimum available slot interval equal to 0 may be explicitly included in the second configuration information or may be indicated by implicit means, such as: the minimum available slot interval indicated by the default second configuration information includes a minimum available value equal to 0 in the TDRA table.

For example, taking the second configuration information implicitly indicates the minimum available slot interval equal to 0, the minimum available slot interval is the minimum available value of K0, and the first usage value configured by the network device to the terminal is 1, the following table eight shows still another implementation form of the second configuration information, such as table eight, where the second configuration information includes two minimum available values of K0 greater than 0: 1 and 2. In this case, if the network device configures the list shown in table eight for the terminal, the terminal may use the smallest one value 1 among the smallest available values that are not 0 as the target timeslot interval; or, the maximum value 2 of the values other than 0 is taken as the target time slot interval; alternatively, the first-used value of 1 is determined as the target slot interval.

Table eight

Index value	The most important of K0Small available value

For another example, taking the second configuration information explicitly indicates a minimum available slot interval equal to 0, the minimum available slot interval is a minimum available value of K0, and the first usage value configured by the network device to the terminal is 1, the following table nine shows yet another implementation form of the second configuration information, such as table nine, where the second configuration information includes three minimum available values of K0 greater than 0: 1. 2 and 3, and also includes the minimum available value of K0 equal to 0. In this case, if the network device configures the list shown in table nine for the terminal, the terminal may use the smallest one value 1 among the smallest available values that are not 0 as the target timeslot interval; or, the maximum value 3 of the values other than 0 is taken as the target time slot interval; alternatively, the value 1 will be determined first as the target slot interval.

Watch nine

Similarly, the method for indicating the minimum available value of K2 by the second configuration information and the method for determining the target value of K2 by the terminal according to the first configuration information and the second configuration information can be referred to as the method (3), and are not repeated.

In the method (4), after receiving the first configuration information and the second configuration information sent by the network device, and before receiving the indication information sent by the network device for indicating the slot interval, the terminal determines one of the minimum available slot intervals configured on the BWP currently activated by the terminal as the target slot interval.

The currently activated BWP of the terminal may include at least one of an uplink BWP and a downlink BWP, and when the currently activated BWP of the terminal is the uplink BWP, the minimum available slot interval configured on the currently activated BWP of the terminal is the uplink minimum available slot interval. When the currently activated BWP of the terminal is the downlink BWP, the minimum available timeslot interval configured on the currently activated BWP of the terminal is the downlink minimum available timeslot interval.

As described above, the network device may configure one or more minimum available timeslot intervals for each BWP (uplink BWP or downlink BWP), and optionally, if the network device configures one minimum available timeslot interval for each BWP, the terminal may determine one minimum available timeslot interval configured on the currently activated BWP as the destination timeslot interval; if the network device configures a plurality of minimum available slot intervals for each BWP, the terminal may determine, as the target slot interval, the largest one of the minimum available slot intervals configured on the BWP currently activated by the terminal, or determine, as the target slot interval, the smallest index value of the minimum available slot intervals configured on the BWP currently activated by the terminal, or determine, as the target slot interval, the largest one of the minimum available slot intervals configured on the BWP currently activated by the terminal, and is not limited.

For example, taking as an example that the terminal may determine, as the target timeslot interval, the largest one of the minimum available timeslot intervals configured on the BWP currently activated by the terminal, if the minimum timeslot interval configured on the uplink BWP currently activated by the terminal includes K2 ═ 1 and K2 ═ 2, the terminal determines, according to the above rule, K2 ═ 2 as the target timeslot interval; if the minimum slot interval configured on the downlink BWP currently activated by the terminal includes K0 ═ 1 and K0 ═ 2, the terminal determines that K0 ═ 2 is the target slot interval according to the above rule. For another example, taking as an example that the terminal may determine, as the target timeslot interval, one of the minimum available timeslot intervals configured on the BWP currently activated by the terminal, where the minimum timeslot interval configured on the uplink BWP currently activated by the terminal includes K2 ═ 1 and K2 ═ 2, and the corresponding index values are 0 and 1, respectively, the terminal determines, according to the above rule, K2 ═ 1 as the target timeslot interval; if the minimum slot interval configured on the downlink BWP currently activated by the terminal includes K0 ═ 1 and K0 ═ 2, and the corresponding index values are 0 and 1, respectively, the terminal determines that K0 ═ 1 is the target slot interval according to the above rule.

Based on the method shown in fig. 8, after the terminal starts its own scheduling switching function, receives the multiple minimum available time slot intervals configured by the network device, and before the terminal does not receive the indication information sent by the network device for indicating a specific time slot interval, the terminal may determine the target time slot interval according to the multiple minimum available time slot intervals configured by the network device.
