The following describes in detail a switching behavior determining method, a parameter information configuring method, a terminal and a device provided by the embodiments of the present application through some embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of a method for determining a switching behavior according to an embodiment of the present application, as shown in fig. 2, including the following steps:

step 201, a terminal acquires switching parameter information, wherein the switching parameter information comprises at least one of the following items: the method comprises the steps of switching a transmitting channel supported by a cell corresponding to the terminal, switching the transmitting channel supported by a frequency domain resource, the number of antenna ports supported by the frequency domain resource, switching a transmitting channel supported by the terminal, switching the transmitting channel supported by the frequency domain resource, switching the frequency domain resource corresponding to the transmitting channel switching time, parallel switching capability of the transmitting channel supported, serial switching capability of the transmitting channel supported, and the maximum switching times within preset time; the frequency domain resource is the frequency domain resource corresponding to the terminal.

The terminal may acquire the handover parameter information by at least one of:

network side equipment configuration, other Sidelink (SL) terminal configuration, protocol specification, pre-configuration.

Wherein, the network side equipment can be configured by downlink control information (Downlink Control Information, DCI), and the other SL terminals can be configured by sidelink control information (Sidelink Control Information, SCI).

The cell corresponding to the terminal may be a cell in which the terminal is located or a cell associated with the terminal.

The frequency domain resource corresponding to the terminal may be a frequency domain resource or a frequency domain resource combination configured by the terminal, or may be a frequency domain resource or a frequency domain resource combination used for terminal transmission. The frequency domain resource combination may be a frequency domain resource pair, or other forms of frequency domain resource combination, for example: a list of frequency domain resources (e.g., band list), or a sequence of frequency domain resources (e.g., band sequence).

In the embodiment of the application, the frequency domain resource comprises one of the following:

band (band), carrier (carrier), bandwidth Part (BWP), resource pool (pool).

The above transmission channel switching type may include at least one of:

different frequency domain resources support simultaneous transmission;

different frequency domain resources do not support simultaneous transmissions.

For example: different carriers, bands or resource pools may be transmitted simultaneously before and/or after the handover, e.g. all uplink or SL transmissions. Alternatively, different carriers, bands or resource pools before and/or after the handover may not be transmitted simultaneously, e.g., uplink or SL transmissions may not be performed simultaneously.

The transmission channel switching mode may be at least one of parallel switching and serial switching, or other modes.

The frequency domain resource corresponding to the above-mentioned transmission channel switching time may be that the transmission channel switching time belongs to the transmission time of the frequency domain resource, that is, the transmission on the frequency domain resource may allow the transmission channel to be switched.

The maximum number of times of switching in the preset time may be the maximum number of times that the terminal can perform the transmission channel switching in the preset time at most. The preset time may be reported by the terminal, for example, the capability information includes the preset time, or configured by the network side device, or agreed by a protocol.

It should be noted that, in the embodiment of the present application, support may be understood as association or correspondence.

Step 202, the terminal determines a transmitting channel switching behavior based on the switching parameter information.

The determining the transmission channel switching behavior based on the switching parameter information may be that the transmission channel is switched on the corresponding frequency domain resource according to the switching parameter information. For example: under the condition of comprising the transmission channel switching type supported by the frequency domain resource, executing the transmission channel switching behavior of the transmission channel switching type supported by the frequency domain resource on the frequency domain resource; also for example: in the case of including the number of antenna ports supported by the frequency domain resource, the transmission channel switching behavior performed on the frequency domain resource is controlled within the number of antenna ports supported by the frequency domain resource; also for example: under the condition that the transmission channel switching mode supported by the terminal is included, determining the transmission channel switching behavior under the transmission channel switching mode supported by the terminal; also for example: determining the transmission channel switching behavior of the frequency domain resource in the transmission channel switching mode supported by the frequency domain resource; also for example: in the case of including the capability of supported parallel switching of the transmission channels, the terminal determines a parallel transmission channel switching behavior; also for example: in the case of including the capability of supported serial switching of the transmission channels, the terminal determines a serial transmission channel switching behavior; also for example: and under the condition that the maximum switching times in the preset time are included, the terminal determines that the switching behavior of the transmitting channel does not exceed the maximum switching times.

It should be noted that, in the embodiment of the present application, the transmission channel switching behavior may also be understood as a transmission behavior of the terminal, for example: the terminal switches from transmission of 1 antenna port to transmission of 2 antenna ports.

In the embodiment of the application, the switching behavior of the transmitting channel is determined based on the switching parameter information because the switching parameter information is acquired, thereby avoiding influencing the switching of the transmitting channel of the terminal and improving the transmission performance of the terminal. For example: the terminal determines the transmitting channel switching behavior based on the switching parameter information in the communication transmission process, and the network side equipment or the SL terminal can also determine the transmitting channel switching behavior of the terminal through the switching parameter information, so that the terminal and the network side equipment or the SL terminal understand the transmitting channel switching behavior consistently, errors caused by the transmitting channel switching behavior are avoided, and the effect of improving the transmission performance of the terminal is achieved.

As an optional implementation manner, the above handover parameter information further includes at least one of the following:

and transmitting the frequency domain resource corresponding to the channel switching time.

The above transmission channel switching type may include at least one of:

In this embodiment, at least one of the transmission channel switching type supported by the cell and the frequency domain resource corresponding to the transmission channel switching time corresponding to the terminal is further configured, so that the terminal can support more transmission channel switching behaviors in the communication transmission process, thereby improving the transmission performance of the terminal. For example: under the condition that the transmitting channel switching type supported by the cell corresponding to the terminal is included, the terminal determines transmitting channel switching behavior under the transmitting channel switching type in the cell; also for example: and under the condition of comprising the frequency domain resource corresponding to the transmission channel switching time, determining the transmission channel switching behavior on the frequency domain resource corresponding to the transmission channel switching time.

As an optional implementation manner, the transmission channel switching type supported by the cell includes at least one of the following:

The first predetermined time, the second predetermined time, and the third predetermined time may be reported by the terminal, where the capability information further includes at least one of the following: the first predetermined time, the second predetermined time, and the third predetermined time. Alternatively, the first predetermined time, the second predetermined time, and the third predetermined time may be defined by a protocol or configured by a network side.

In some embodiments, the first predetermined time, the second predetermined time, and the third predetermined time may not be configured, or the first predetermined time, the second predetermined time, and the third predetermined time may be 0.

Alternatively, the fourth predetermined time, the fifth predetermined time, and the sixth predetermined time may be defined by a protocol or configured by a network side.

In some embodiments, the fourth predetermined time, the fifth predetermined time, the sixth predetermined time, or the fourth predetermined time, the fifth predetermined time, and the sixth predetermined time may not be configured as 0.

In this embodiment, a plurality of serial switching may be supported to improve the transmission channel switching performance of the terminal.

As an optional implementation manner, the handover parameter information further includes:

and the identification information of the frequency domain resource.

The identification information may be a resource index, for example: the identification information may include at least one of:

carrier index, band index, resource pool index, and BWP index.

In this embodiment, since the identification information of the frequency domain resources is configured, the switching parameter corresponding to each frequency domain resource can be accurately located through the identification information.

Optionally, the identification information is used for at least one of the following:

determining a number of antenna ports supporting transmission on the frequency domain resource;

and the frequency domain resource corresponding to the transmitting channel switching time is determined.

The number of antenna ports for transmission supported on the frequency domain resource can be determined by the identification information, so that the transmission channel switching can be performed based on the number of antenna ports.

The above-mentioned frequency domain resource for determining the transmission channel switching time may be that which frequency domain resource the transmission channel switching time corresponds to is determined by the above-mentioned identification information, specifically may be that the transmission channel switching time is included in the transmission time of which frequency domain resource, for example: the method comprises N frequency domain resources, and the identification information of each frequency domain resource can determine whether the switching time of the transmitting channel corresponds to the frequency domain resource.

In this embodiment, the number of antenna ports supporting transmission on the frequency domain resource can be determined by the identification information, and whether the frequency domain resource corresponds to the transmission channel switching time can also be determined, so that the accuracy of switching the transmission channel of the terminal can be higher by the identification information.

Optionally, in the case that the identification information of at least two frequency domain resources associated with the transmission channel switching behavior is the same, the method further includes:

and determining target identification information of the switching behavior of the at least two frequency domain resources in the transmitting channel according to the parameter information of the frequency domain resources.

The parameter information of the frequency domain resource may include at least one of the following:

bandwidth, band index, frequency domain location, subcarrier spacing, cyclic Prefix (CP) type.

The frequency domain position is a frequency domain position which distinguishes at least two frequency domain resources.

The determining the target identification information of the at least two frequency domain resources in the transmitting channel switching behavior according to the parameter information of the frequency domain resources may be further distinguishing the frequency domain resources according to the distinction between the parameter information of the at least two frequency domain resources, or determining the target identification information of each frequency domain resource according to the protocol definition or the rule of determining the identification information according to the parameter information configured by the network side.

The target identification information of the at least two frequency domain resources in the transmission channel switching behavior may be identification information for further distinguishing the at least two frequency domain resources in the transmission channel switching behavior, so as to complete transmission channel switching in the at least two frequency domain resources through the target identification information.

Optionally, the terminal does not expect network side configuration or triggering: and switching a transmission channel between at least two frequency domain resources with the same identification information.

The terminal does not expect the network side to configure or trigger the transmission channel switching, and if the network side configures or triggers the transmission channel switching, the terminal considers that the configuration or the triggering is error configuration or triggering, and the terminal does not respond, so as to avoid error occurrence. Or, in the case that the network side configures or triggers the above-mentioned transmission channel switching, the terminal needs to further distinguish the frequency domain resources to perform the transmission channel switching.

For example: when the target identifier is a carrier index, for example, the network side device configures the number of antenna ports of a carrier through the carrier index, the terminal calculates the number of antenna ports corresponding to the carrier through the number of antenna ports of each carrier index and the carrier index of a certain carrier, and when the carrier indexes of at least two carriers are the same, the terminal further determines the carrier index during switching according to at least one of bandwidth, frequency band index, frequency domain position, subcarrier spacing and CP type. And the terminal does not expect network configuration or trigger such a handoff between multiple identical carrier indexes.

As an alternative embodiment, in the case that the transmission channel switching time is included in the transmission time of at least two frequency domain resources, a corresponding one of the at least two frequency domain resources is determined according to the parameter information of the frequency domain resources.

Wherein, the parameter information may include at least one of the following:

The determining, according to the parameter information of the frequency domain resources, that the transmission channel switching time corresponds to one frequency domain resource in the at least two frequency domain resources may be determining, in the at least two frequency domain resources, one frequency domain resource corresponding to the transmission channel switching time. For example: and determining the frequency domain resource corresponding to the transmission channel switching time according to the difference between the parameter information of at least two frequency domain resources, or determining the frequency domain resource corresponding to the transmission channel switching time based on the parameter information according to the protocol definition or the rules configured by the network side.

Optionally, the terminal does not expect network side configuration or triggering: and transmitting channel switching between at least two frequency domain resources including the transmitting channel switching time at the transmission time.

The terminal does not expect the network side to configure or trigger the transmission channel switching, and if the network side configures or triggers the transmission channel switching, the terminal considers that the configuration or the triggering is error configuration or triggering, and the terminal does not respond, so as to avoid error occurrence. Or under the condition that the network side configures or triggers the transmission channel switching, the terminal needs to further determine which frequency domain resource corresponds to the transmission channel switching time to perform the transmission channel switching.

In this embodiment, since the corresponding one of the at least two frequency domain resources is determined according to the parameter information of the frequency domain resources, the problem that the terminal cannot perform transmission channel switching when the transmission channel switching time is included in the transmission time of the at least two frequency domain resources can be avoided.

For example: and acquiring switching position information of the carrier, wherein the switching position information can be configured by a network side or defined by a protocol and is used for representing the switching time of a transmitting channel, for example, the switching position information can be TxSwitchingPeriodLocation, and the value of the switching position information is true/false or 1/0 so as to represent whether the switching time of the transmitting channel belongs to the transmission time of the carrier. And when the switching position information corresponding to at least two carriers is the same, determining which carrier the switching time of the transmitting channel is according to at least one of bandwidth, frequency band index, frequency domain position, subcarrier spacing and CP type. And the terminal does not expect network configuration or trigger switching between multiple carriers with the same txswitchingperiod location.

As an optional implementation manner, the identification information of the N carriers corresponding to the transmission channel switching behavior is associated with at least one of the following:

the maximum frequency band switching number supported by the terminal;

the maximum carrier switching number supported by the terminal;
