Description

Signaling switching method, communication device and storage medium TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, in particular to a signaling switching method, a communication device and a storage medium. BACKGROUND

[0002] For the immersive communication scenario of 5G-A or 6G, there are some high-latency large data transmission services. In the current scheme, if the radio resource control (RRC) signaling configuration parameters need to be changed, the RRC signaling reconfiguration mechanism needs to be started. Under the RRC signaling reconfiguration mechanism, the understanding of the alignment between the base station and the user equipment (UE) needs a long time, which is not friendly to these high-latency large data services. For example, during the transmission of a video service, the video service usually has a frame rate requirement, for example, the frame rate can be 60 frames per second. However, due to changes in user requirements, the frame rate will also change accordingly, for example, 120 frames per second. Generally, the frame rate will correspond to a set of RRC signaling configurations. Due to the change of the frame rate, the RRC signaling needs to be reconfigured. However, the time of the reconfiguration process is relatively long, and accordingly, a large number of data packets may be lost during the reconfiguration process, resulting in that the transmission data resources cannot adapt to the higher frame rate of video transmission. Therefore, how to quickly switch the RRC signaling configuration to avoid the operation of RRC reconfiguration is a problem to be solved. SUMMARY

[0030] In an embodiment, FIG. 1 is a flowchart of a signaling switching method according to an embodiment of the present application. The present embodiment is applied to the case of fast switching of RRC signaling in an immersive communication scenario. The present embodiment can be performed by a first communication device.

[0031] As shown in FIG. 1, the present embodiment includes S110-S120.

[0032] S110, receiving a set of RRC signaling; wherein the set of RRC signaling includes at least two different types of RRC signaling.

[0033] wherein the RRC signaling set is configured to contain all types of RRC signaling that the first communication device can employ. In an embodiment, the RRC signaling set comprises at least two different types of RRC signaling. Exemplarily, the types of RRC signaling can include, but are not limited to, one of the following: default RRC signaling, compact RRC signaling, and switching RRC signaling.

[0034] S120, activating the RRC signaling in the RRC signaling set based on a first activation condition.

[0035] wherein the first activation condition is configured to trigger a condition for the first communication device to activate one of the RRC signaling in the RRC signaling set, or to trigger a condition for the first communication device to switch from one RRC signaling to another RRC signaling, or to trigger a condition for the first communication device to switch from one RRC signaling configuration mode to another RRC signaling configuration mode, or to trigger a condition for the first communication device to switch from one RRC signaling combination to another RRC signaling combination. In an embodiment, after the first communication device receives the RRC signaling set sent by the second communication device, the first communication device selects and activates one of the RRC signaling in the RRC signaling set at the moment when the first activation condition is triggered, or directly switches from one RRC signaling to another RRC signaling, or directly switches from one RRC signaling configuration mode to another RRC signaling configuration mode, or directly switches from one RRC signaling combination to another RRC signaling combination, without the need to reconfigure the RRC signaling, thereby achieving faster RRC signaling configuration and adapting to service transformation, thereby reducing latency and improving system performance.

[0036] In an embodiment, the set of RRC signaling includes at least a first RRC signaling and a second RRC signaling; wherein the first RRC signaling and the second RRC signaling are two different types of RRC signaling. Exemplarily, the first RRC signaling and the second RRC signaling can include, but are not limited to, a default RRC signaling, a compact RRC signaling and a switching RRC signaling. In an example, when the first RRC signaling is the default RRC signaling, the second RRC signaling can include the compact RRC signaling and the switching RRC signaling. Specifically, the first RRC signaling is the default RRC signaling, and the second RRC signaling is the compact RRC signaling. Optionally, the default RRC signaling includes default configuration parameters, and the compact RRC signaling includes one or more specific configuration parameters. Optionally, there is only one default RRC signaling, and the compact RRC signaling can include multiple. Optionally, the first communication device activates the RRC signaling composed of the default RRC signaling and one activated compact RRC signaling. Specifically, the first RRC signaling is the default RRC signaling, and the second RRC signaling is the switching RRC signaling. Optionally, the default RRC signaling includes all configuration parameters, and the compact RRC signaling includes all configuration parameters. Optionally, the first communication device activates the RRC signaling as the default RRC signaling or the switching RRC signaling. In an example, when the first RRC signaling is the compact RRC signaling, the second RRC signaling can include the default RRC signaling. In an example, when the first RRC signaling is the switching RRC signaling, the second RRC signaling can include the default RRC signaling. In an example, the first RRC signaling can also be a first RRC signaling combination, i.e., the first RRC signaling includes a combination of multiple RRC signaling; and the second RRC signaling can also be a second RRC signaling combination, i.e., the second RRC signaling includes a combination of multiple RRC signaling. In an example, when the first RRC signaling or the second RRC signaling is a combination of multiple RRC signaling, the multiple RRC signaling included in the first RRC signaling is of the same type of RRC signaling, and the multiple RRC signaling included in the second RRC signaling is of the same type of RRC signaling, and the first RRC signaling and the second RRC signaling are two different types of RRC signaling.

[0037] In the embodiments of the present application, activating the RRC signaling can also be referred to as switching the RRC signaling, using the RRC signaling, applying the RRC signaling, enabling the RRC signaling or adopting the RRC signaling. Not activating the RRC signaling can also be referred to as not switching the RRC signaling, not using the RRC signaling, not applying the RRC signaling, not enabling the RRC signaling or not adopting the RRC signaling.

[0038] In an embodiment, the RRC signaling in the RRC signaling set is activated based on the first activation condition, including one of the following: the first RRC signaling is not activated when the second RRC signaling is activated. Specifically, the first RRC signaling is a default RRC signaling, and the second RRC signaling is a handover RRC signaling. When the handover RRC signaling is activated, the first communication device deactivates or does not activate the default RRC signaling. Specifically, the first RRC signaling is a handover RRC signaling 1, and the second RRC signaling is a handover RRC signaling 2. When the handover RRC signaling 2 is activated, the first communication device deactivates or does not activate the handover RRC signaling 1. The first RRC signaling is activated when the second RRC signaling is activated. Specifically, the first RRC signaling is a default RRC signaling, and the second RRC signaling is a reduced RRC signaling. The first communication device receives an RRC signaling set configuration, where the RRC signaling set includes one default RRC signaling and multiple reduced RRC signaling. The first communication device activates the default RRC signaling and one reduced RRC signaling. The first RRC signaling is activated, and the second RRC signaling is not activated. In an example, at the time when the first communication device responds to the first activation condition, the first communication device can activate one of the RRC signaling in the RRC signaling set, such as activating the second RRC signaling in the RRC signaling set but not activating the first RRC signaling, or activating the first RRC signaling in the RRC signaling set but not activating the second RRC signaling. In an example, at the time when the first communication device responds to the first activation condition, the first communication device can activate all the RRC signaling in the RRC signaling set, i.e., activating the first RRC signaling and the second RRC signaling.

[0039] In an embodiment, the time required for activating the RRC signaling in the RRC signaling set is less than the latency requirement for processing the RRC procedure. In an example, the latency for processing the RRC procedure refers to the processing latency required for switching from one RRC signaling to another RRC signaling. Correspondingly, the time required for the first communication device to activate one of the RRC signaling in the RRC signaling set needs to be less than the latency requirement for processing the RRC procedure, so as to enable the RRC signaling configuration to adapt to the service change faster.

[0040] In an embodiment, the RRC signaling is related to one of the following configurations: a radio resource configuration; a measurement configuration. In an example, the RRC signaling can be configured by the radio resource configuration, or the RRC signaling can be configured by the measurement configuration.

[0041] In an embodiment, the radio resource configuration includes at least one of the following signaling: a grant scheduling signaling for configuring a non-dynamic scheduling uplink transmission; a signaling for configuring a physical downlink control channel monitoring occasion.

[0042] In an embodiment, the measurement configuration includes: a configuration signaling of at least one measurement set.

[0043] In an embodiment, the first RRC signaling or the second RRC signaling comprises grant scheduling signaling for configuring the non-dynamically scheduled uplink transmission; the different configuration parameters between the first RRC signaling and the second RRC signaling comprise at least one of the following: a periodicity parameter; an offset parameter; a time domain resource allocation; a frequency domain resource allocation; a modulation and coding scheme level; a number of slots in a period; a length of unused transmission occasion uplink control information; and an offset value of unused transmission occasion uplink control information. For example, the grant scheduling signaling for configuring the non-dynamically scheduled uplink transmission is ConfiguredGrantConfig signaling, and the configuration parameters comprise a periodicity parameter, a TimeDomainOffset parameter, a TimeDomainAllocation parameter, a FrequencyDomainAllocation parameter, a mcsAndTBsize parameter, a nrofSlotsInCG-Period parameter, a nrofBitsInUTO-UCI parameter, and a betaOffsetUTO-UCI parameter. In an example, in the case that the first RRC signaling and the second RRC signaling comprise grant scheduling signaling for configuring the non-dynamically scheduled uplink transmission, at least one of the configuration parameters between the first RRC signaling and the second RRC signaling is different, such as one or more of the following: a periodicity parameter, an offset parameter, a time domain resource allocation, a frequency domain resource allocation, a modulation and coding scheme level, a number of slots in a period, a length of unused transmission occasion uplink control information, and an offset value of unused transmission occasion uplink control information. In an example, the different configuration parameters comprise at least one of the following: a presence or absence of a configuration parameter, or a different value of a configuration parameter. Specifically, the first RRC signaling does not comprise a configuration parameter, and the second RRC signaling comprises the configuration parameter. For example, the first RRC signaling does not comprise a periodicity parameter. The second RRC signaling is dedicated to configuring a periodicity parameter and comprises one or more periodicity parameters. The first communication device activates the first RRC signaling and activates one of the periodicity parameters of the second RRC signaling. The first communication device applies the parameters in the first RRC signaling and the activated periodicity parameter of the second RRC signaling to the grant scheduling signaling for configuring the non-dynamically scheduled uplink transmission. Specifically, the first RRC signaling and the second RRC signaling both comprise all configuration parameters, but some of the configuration parameters have different values. For example, the first RRC signaling comprises a periodicity parameter with a first value, and the second RRC signaling comprises a periodicity parameter with a second value. The first communication device applies the first RRC signaling or the second RRC signaling to the grant scheduling signaling for configuring the non-dynamically scheduled uplink transmission.The different cases of the different of the offset parameter, the time domain resource allocation parameter, the frequency domain resource allocation parameter, and the modulation and coding scheme level parameter, the number of slots within a period, the length of the uplink control information on the unused transmission occasion, and the offset value of the uplink control information on the unused transmission occasion are the same as the different of the periodicity parameter.

[0044] Specifically, the RRC signaling includes a configured grant signaling for configuring the uplink transmission of the non-dynamic scheduling. Optionally, the fast switching process of the RRC signaling occurs when the UE is in the RRC connected state. Optionally, the configuration parameters of the first RRC signaling or the second RRC signaling are denoted as configuredGrantConfig, and the configuration parameters that need to be fast switched include: periodicity, offset (Type 1), time domain resource assignment (TDRA), frequency domain resource assignment (FDRA), or modulation and coding scheme (MCS).

[0045] Specifically, the RRC signaling set configures a configuredGrantConfig-based RRC signaling set. That is, the RRC signaling set includes one or more configuredGrantConfig.

[0046] In an example, the RRC signaling set includes one default RRC signaling (first RRC signaling) such as configuredGrantConfig-default and one compact RRC signaling (second RRC signaling). Optionally, the default RRC signaling is used for configuring non-dynamically scheduled uplink transmission, such as Type 1 transmission mode (configured activation by RRC parameters only) or Type 2 transmission mode (configured activation by RRC and DCI signaling), which contains all parameters of current Configured Grant (CG) scheduling mode (e.g., same configuration as ConfiguredGrantConfig in related protocol) except for parameters that need to be switched quickly. Optionally, the compact RRC signaling is also used for configuring non-dynamically scheduled uplink transmission. Unlike the default RRC signaling, the compact RRC signaling only includes one or more configuration parameters that need to be switched quickly. For example, a periodicity parameter. The periodicity only includes the periodicity parameter value in the default RRC parameter. For example, only includes some periodicity values that have a multiple relationship, such as sym8x14, sym16x14, sym32x14, or sym64x14. One compact RRC parameter can include only one periodicity parameter, or can include multiple periodicity parameters.

[0047] Optionally, the switching of offset parameter (Offset (Type 1)), time domain resource allocation (TDRA), frequency domain resource allocation (FDRA), or modulation and coding scheme (MCS) level is the same as the example of the periodicity parameter.

[0048] Specifically, the default RRC signaling (first RRC signaling) such as configuredGrantConfig-default includes all configuration parameters of the grant scheduling of the non-dynamically scheduled uplink transmission except for the periodicity parameter. The compact RRC signaling (second RRC signaling) includes one or more periodicity parameters. The compact RRC signaling is a list, a sequence, or other forms. The list or sequence includes one or more periodicity parameters. When the second communication node configures the RRC signaling set, the default RRC signaling (first RRC signaling) is activated, and the compact RRC signaling (second RRC signaling) activates one of the periodicity parameters through the first activation condition. The first communication device activates configuredGrantConfig-default and one periodicity parameter for the configuration of the grant scheduling of the non-dynamically scheduled uplink transmission.

[0049] In an example, the RRC parameter set includes one default RRC signaling (first RRC signaling) such as configuredGrantConfig and one or more switching RRC signaling (second RRC signaling). Optionally, the default RRC signaling and the switching RRC signaling are both used for configuring the non-dynamic scheduling uplink transmission.

[0050] Specifically, the default RRC signaling (first RRC signaling) includes all configuration parameters of the grant scheduling based on the non-dynamic scheduling uplink transmission. The switching RRC signaling (second RRC signaling) includes all configuration parameters of the grant scheduling based on the non-dynamic scheduling uplink transmission. The different RRC signaling, including the first RRC signaling and the second RRC signaling and the different second RRC signaling, has different parameter values for fast switching and the same parameter values for other parameters. For example, the parameter that needs to be fast switched is the periodicity parameter, and the periodicity parameter of the RRC signaling in the RRC parameter set only takes one value, the periodicity parameter of the different RRC signaling takes different values, and the other parameter values or value ranges are the same. The first communication device activates the default RRC signaling (first RRC signaling) or the switching RRC signaling (second RRC signaling) for the configuration of the grant scheduling of the non-dynamic scheduling uplink transmission.

[0051] Specifically, the default RRC signaling (first RRC signaling) and the switching RRC signaling (second RRC signaling) are numbered by introducing an index, and the RRC signaling is configured to the non-dynamic scheduling uplink transmission mode by selecting different numbers. For example, in BWP-uplinkDedicated, a new RRC parameter table (denoted as ConfiguredGrantConfigList) is defined, which contains multiple ConfiguredGrantConfig (i.e., default RRC parameters and switching RRC parameters), indicating that the ConfiguredGrantConfig configuration in a BWP can be fast switched.

[0052] In an example, the set of RRC signaling includes a first RRC signaling and a second RRC signaling, wherein the first RRC signaling or the second RRC signaling includes a combination of a plurality of RRC signaling (predefined configuration pattern). Optionally, the combination of RRC signaling (predefined configuration pattern) is one default RRC signaling and a plurality of compact RRC signaling. For example, the compact RRC signaling is periodicity parameter, there can be 4 compact RRC signaling, including sym8x14, sym16x14, sym32x14 and sym64x14, corresponding to IE1, IE2, IE3 and IE4, then the RRC signaling combination predefined configuration pattern can include: {IE1, IE2, IE3, IE4}, {IE2, IE1, IE3, IE4} and any order combination, these patterns are encoded by codepoint. At the same time, each RRC signaling configuration is valid for a time. For example, the valid time is 5ms, {IE1, IE2, IE3, IE4} means that the periodicity of sym8x14 is used for 1-5ms, the periodicity of sym16x14 is used for 6-10ms, the periodicity of sym32x14 is used for 11-15ms, and the periodicity of sym64x14 is used for 16-20ms, and if no other RRC signaling combination is activated after the 20th ms, the RRC signaling is activated according to the order of the current RRC signaling combination. The first communication node configures the non-dynamically scheduled uplink transmission grant scheduling according to the RRC signaling in the RRC signaling combination. Optionally, the combination of RRC signaling (predefined configuration pattern) includes a default RRC signaling and a plurality of switching RRC signaling. For example, there are 4 different configurations of IE1, IE2, IE3 as switching RRC signaling 1-3, and IE0 as default RRC signaling. The configuration pattern can be IE0, IE1, IE2, IE3, etc., and these patterns can be encoded by codepoint. At the same time, each RRC signaling configuration is valid for a time. For example, the valid time is 5ms, {IE0, IE1, IE2, IE3, IE4} means that the default RRC signaling is used for 1-5ms, the RRC signaling 1 is used for 6-10ms, the RRC signaling 2 is used for 11-15ms, and the RRC signaling 3 is used for 16-20ms, and if no other RRC signaling combination is activated after the 20th ms, the RRC signaling is activated according to the order of the current RRC signaling combination. Optionally, a list, ConfiguredGrantConfigPatternList, can be added to the above example to save different predefined configuration patterns.

[0053] In an embodiment, the first RRC signaling or the second RRC signaling comprises signaling for configuring a physical downlink control channel monitoring occasion; the different configuration parameters between the first RRC signaling and the second RRC signaling comprise at least one of: time-frequency resource configuration signaling; a number of slots occupied by a physical downlink control channel (PDCCH) in time domain; a periodicity and offset value of a monitoring occasion; a starting symbol position of the PDCCH in a slot; an aggregation level. For example, the signaling for the PDCCH monitoring occasion is SearchSpace signaling, the configuration parameters comprise time-frequency resource configuration signaling CORESET, different time-frequency resource configuration signaling is represented by controlResourceSetID; a number of slots occupied by the PDCCH in time domain parameter duration; a periodicity and offset value of a monitoring occasion monitoringSlotPeriodicityAndOffset; a starting symbol position of the PDCCH in a slot monitoringSymbolsWithinSlot; an aggregation level parameter nrofCandidates. In an example, in the case that the first RRC signaling and the second RRC signaling comprise signaling for configuring a physical downlink control channel monitoring occasion, the first RRC signaling and the second RRC signaling comprise at least one different configuration parameter, for example, one or more of the following configuration parameters can be different: time-frequency resource configuration signaling, a number of slots occupied by the PDCCH in time domain, a periodicity and offset value of a monitoring occasion, a starting symbol position of the PDCCH in a slot, an aggregation level. In an example, the different configuration parameters comprise at least one of the following: presence or absence of a configuration parameter, or different values of a configuration parameter. Specifically, the first RRC signaling does not comprise a configuration parameter, and the second RRC signaling comprises the configuration parameter. For example, the first RRC signaling does not comprise a periodicity and offset value of a monitoring occasion. The second RRC signaling is specifically used for configuring a periodicity and offset value of a monitoring occasion, and comprises one or more periodicity and offset values of a monitoring occasion. The first communication device activates the first RRC signaling, and simultaneously activates a periodicity and offset value of a monitoring occasion of the second RRC parameter. The first communication device applies the parameters in the first RRC signaling and the activated periodicity parameter in the second RRC signaling as the signaling of the physical downlink control channel monitoring occasion. Specifically, the first RRC signaling and the second RRC parameter both comprise all configuration parameters, but some of the configuration parameters have different values. For example, the first RRC signaling comprises a periodicity and offset value of a monitoring occasion, and takes a first value, the second RRC signaling comprises a periodicity parameter, and takes a second value, or the first RRC signaling comprises a periodicity and offset value of a monitoring occasion, and takes a first combination of values, the second RRC signaling comprises a periodicity parameter, and takes a second combination of values.The first communication device applies the first RRC signaling or the second RRC signaling for configuring grant scheduling signaling of uplink transmission of non-dynamic scheduling, wherein the combination value represents a combination of the period and the offset value. The time-frequency resource configuration signaling; the number of slots occupied by the PDCCH in the time domain; the starting symbol position of the PDCCH in the slot; the different aggregation levels are the same as the different cases of the period and the offset value of the monitoring occasion.

[0054] Specifically, the RRC signaling includes signaling for a physical downlink control channel monitoring occasion. Optionally, the fast switching process of the RRC signaling occurs when the UE is in an RRC connected state.

[0055] Specifically, the configuration parameter of the RRC signaling is denoted as ControlResourceSet, and the switching parameter includes: frequency domain resource occupation of transmitting PDCCH frequencyDomainResources, time domain resource occupation of transmitting PDCCH duration, mapping mode of CCE-REG, scrambling ID of PDCCH, etc.

[0056] Specifically, the configuration parameter of the RRC signaling is denoted as searchSpace, and the switching parameter includes: the period and the offset of searchSpace monitoringSlotPeriodicityAndOffset, the number of slots occupied by the PDCCH in the time domain duration, the starting symbol position of the PDCCH in the slot monitoringSymbolsWithinSlot, and the aggregation level nrofCandidates.

[0057] Specifically, the RRC layer configures a ControlResourceSet-based RRC signaling set, that is, the RRC signaling set includes one or more ControlResourceSet.

[0058] In an example, the parameter set composition includes a default RRC signaling (first RRC signaling) such as ControlResourceSet-default and a compact RRC signaling (second RRC signaling) configuration. Optionally, the default RRC signaling is used to configure the PDCCH resource occupation, which contains all the parameters in the current PDCCH resource occupation (e.g., the same configuration as ControlResourceSet in the relevant protocol) except for the parameters that need to be quickly switched, such as frequenceDomainResources and / or duration. Optionally, the compact RRC signaling only includes the parameters that need to be quickly switched, such as frequenceDomainResources and / or duration, which are also used to configure the PDCCH resource occupation. Unlike the default RRC signaling, the compact RRC signaling only includes the parameters that need to be quickly switched, such as frequenceDomainResources and / or duration. For example, only a few specific time-frequency resource occupation combinations are included, frequenceDomainResources = 111111000000.... and duration = 2, etc. A compact RRC parameter can include only one time-frequency resource occupation combination, or it can include multiple time-frequency resource occupation combinations.

[0059] Optionally, the mapping of CCE-REG, the scrambling ID of PDCCH, the period and offset (monitoringSlotPeriodicityAndOffset) in searchSpaceRRC signaling, the number of slots occupied by PDCCH in the time domain (duration), the starting symbol position of PDCCH in the slot (monitoringSymbolsWithinSlot), and the switching of aggregation levels (nrofCandidates) are the same as the examples of time-frequency resources.

[0060] Specifically, the default RRC signaling (first RRC signaling) such as ControlResourceSet-default includes all configuration parameters except for the time-frequency resource occupation parameters based on the configuration of the PDCCH resource occupation. The compact RRC signaling (second RRC signaling) includes one or more time-frequency resource occupation combinations. When the second communication node configures the RRC signaling set, the default RRC signaling (first RRC signaling) is activated, and the compact RRC signaling (second RRC signaling) activates one of the time-frequency resource occupation combinations through the first activation condition. The first communication device activates ControlResourceSet-default and a time-frequency resource occupation combination to configure the PDCCH resource occupation.

[0061] For example, the frequenceDomainResources and duration in the default RRC signaling structure are deleted.

[0062] All the simplified RRC signaling forms a list (or other forms), and the configuration parameter list structure of the simplified RRC signaling is added with frequenceDomainResources and duration, for example, the time-frequency resource occupation parameter frequenceDomainResources = 111111000000.... & duration = 2, etc.

[0063] In an example, the parameter set forms a configuration including the default RRC signaling (first RRC signaling) and the switching RRC signaling (second RRC signaling), and optionally, the default RRC signaling (first RRC signaling) and one or more switching RRC signaling (second RRC signaling) are used for the configuration of the PDCCH time-frequency resource occupation.

[0064] Specifically, the default RRC signaling (first RRC signaling) includes all the configuration parameters of the configuration of the PDCCH time-frequency resource occupation. The switching RRC signaling (second RRC signaling) includes all the configuration parameters of the configuration of the PDCCH time-frequency resource occupation. Different RRC signaling, including the first RRC signaling and the second RRC signaling and the fast switching of different second RRC signaling, have different parameter values, and other parameter values are the same. For example, the parameter that needs to be fast switched is the time-frequency resource occupation combination, and the time-frequency resource occupation combination of the RRC signaling in the RRC parameter set only takes one combination value. The period parameter values of different RRC signaling are different, and other parameter values or value ranges are the same. The first communication device activates the default RRC signaling (first RRC signaling) or the switching RRC signaling (second RRC signaling) for all the configuration parameters of the configuration of the PDCCH time-frequency resource occupation.

[0065] Specifically, the default RRC signaling (first RRC signaling) and the switching RRC signaling (second RRC signaling) are numbered by introducing indexes, and the RRC signaling is configured to the non-dynamic scheduling uplink transmission mode by selecting different numbers. For example, in order to make the resource configuration more flexible and variable, the combination of multiple CORESET IDs in the entry of the List is allowed under the premise of satisfying the predefined maximum CORESET configuration quantity. For example, the content of the enhanced List includes: controlResourceSetToAddModList. For example, both the default RRC signaling and the switching RRC signaling include the ControlResourceSet function, and at least controlResourceSetId, frequencyDomainResources and duration are contained in the function.

[0066] In an example, the set of RRC signaling includes a first RRC signaling and a second RRC signaling, wherein the first RRC signaling or the second RRC signaling includes a combination of a plurality of RRC signaling (predefined configuration mode). Optionally, the combination of RRC signaling (predefined configuration mode) is one default RRC signaling and a plurality of reduced RRC signaling. For example, the reduced RRC signaling is a time-frequency resource occupation combination, there can be 4 reduced RRC signaling, respectively including frequenceDomainResources = 111111000000000000 & duration = 2, frequenceDomainResources = 011111000000000000 & duration = 3, frequenceDomainResources = 001111000000000000 & duration = 4, and frequenceDomainResources = 000111000000000000 & duration = 5 configuration, corresponding to IE1, IE2, IE3 and IE4, then the RRC signaling combination predefined configuration mode can include: {IE1, IE2, IE3, IE4}, {IE2, IE1, IE3, IE4} and any order combination, these modes are encoded by codepoint. At the same time, each RRC signaling configuration takes effect for a time. For example, the effective time is 5ms, {IE1, IE2, IE3, IE4} is represented as, 1-5ms uses IE1, frequenceDomainResources = 111111000000000000 & duration = 2, 6-10ms uses IE2, frequenceDomainResources = 011111000000000000 & duration = 3, 11-15ms uses IE3, frequenceDomainResources = 001111000000000000 & duration = 4, 16-20ms uses IE4, frequenceDomainResources = 000111000000000000 & duration = 5, if no other RRC signaling combination is activated after reaching the 20th ms, then the RRC signaling is activated according to the order of the current RRC signaling combination. The first communication node configures the physical downlink control channel monitoring occasion according to the RRC signaling in the RRC signaling combination. Optionally, the combination of RRC signaling (predefined configuration mode) includes a default RRC signaling and a plurality of switching RRC signaling. For example, there are 4 different configurations of IE1, IE2, IE3 as switching RRC signaling 1-3; IE0 is the default RRC signaling.The configuration mode can be IE0, IE1, IE2, IE3, etc., which can be encoded by codepoint. At the same time, each RRC signaling configuration takes effect at a certain time. For example, the effective time is 5ms, and {IE0, IE1, IE2, IE3, IE4} means that 1-5ms uses the default RRC signaling, 6-10ms uses RRC signaling 1, 11-15ms uses RRC signaling 2, 16-20ms uses RRC signaling 3, and if no other RRC signaling combination is activated after the 20th ms, the RRC signaling combination will continue to be activated in the order of the current RRC signaling combination. Optionally, a list, CoResourceSetList, can be added to the above example to save different predefined configuration modes.

[0067] In an example, the second communication node configures a SearchSpace-based RRC signaling set. The configuration method is similar to the ControlResourceSet configuration.

[0068] Optionally, the RRC signaling combination includes the configuration of the default RRC signaling and the compact RRC signaling, which is the same as the above CORESET RRC signaling combination method.

[0069] Optionally, the RRC signaling combination includes the configuration of the default RRC signaling and the switching RRC signaling, which is the same as the above CORESET RRC signaling combination method.

[0070] Optionally, the RRC signaling combination includes a predefined configuration mode, which is the same as the above CORESET RRC parameter signaling combination method.

[0071] In an embodiment, the first RRC signaling or the second RRC signaling comprises configuration signaling of at least one measurement set. In an example, the measurement set configuration comprises one or more of the following: measurement configuration, physical downlink control channel monitoring occasion configuration, discontinuous reception configuration, sounding reference signal configuration, grant scheduling configuration for non-dynamically scheduled uplink transmission, channel state information reference signal measurement or reporting configuration, or semi-persistent scheduling configuration. For example, the measurement configuration is MeasGapConfig, the measurement configuration is MeasObjectNR, the discontinuous reception configuration is DRX-Config, the sounding reference signal configuration is SRS-Config, the channel state information reference signal measurement configuration is CSI-MeasConfig, the channel state information reference signal reporting configuration is CSI-ReportConfig, and the semi-persistent scheduling configuration is SPS-config. For example, the measurement set configuration comprises measurement configuration, physical downlink control channel monitoring occasion configuration, and semi-persistent scheduling configuration. For example, the measurement set configuration comprises measurement configuration, physical downlink control channel monitoring occasion configuration, and grant scheduling configuration for non-dynamically scheduled uplink transmission. For example, the measurement set configuration comprises measurement configuration and discontinuous reception configuration. The different configuration parameters between the first RRC signaling and the second RRC signaling comprise at least one of the following: measurement configuration period, measurement configuration window length, measurement configuration quantity, semi-persistent scheduling period, grant scheduling period for configured grant, PDCCH monitoring occasion period, PDCCH monitoring occasion duration, PDCCH control resource time-frequency resource, discontinuous reception configuration period, discontinuous reception configuration offset, discontinuous reception configuration quantity, and discontinuous reception on-duration timer. In an example, the measurement configuration refers to configuration information for measuring channel quality of a neighbor cell of the first communication device, or configuration information for measuring channel quality of a serving cell of the first communication device. The first communication device can determine whether to perform cell handover or cell reselection based on relevant information of the measurement configuration. In an example, in the case that the first RRC signaling and the second RRC signaling are configuration signaling of at least one measurement set, the first RRC signaling and the second RRC signaling comprise at least one different configuration parameter, such as at least one of the following: measurement configuration period, measurement configuration window length, measurement configuration quantity, semi-persistent scheduling period, grant scheduling period for configured grant, PDCCH monitoring occasion period, PDCCH monitoring occasion duration, PDCCH control resource time-frequency resource, discontinuous reception configuration period, discontinuous reception configuration offset, discontinuous reception configuration quantity, and discontinuous reception on-duration timer. For example, the measurement set configured by the first RRC signaling comprises one measurement configuration, physical downlink control channel monitoring occasion configuration, and semi-persistent scheduling configuration. The measurement set configured by the second RRC signaling comprises one measurement configuration, physical downlink control channel monitoring occasion configuration, and semi-persistent scheduling configuration.The period of the measurement configuration in the measurement set configured by the first RRC signaling is different from the period of the measurement configuration in the measurement set configured by the second RRC signaling; the physical downlink control channel monitoring occasion configuration in the measurement set configured by the first RRC signaling is different from the period and offset of the physical downlink control channel monitoring occasion configuration in the measurement set configured by the second RRC signaling; the semi-static scheduling configuration in the measurement set configured by the first RRC signaling is different from the period of the semi-static scheduling configuration in the measurement set configured by the second RRC signaling.

[0072] Specifically, the RRC signaling includes measurement set configuration. Optionally, the fast switching process of the RRC signaling occurs when the UE is in an RRC connected state.

[0073] In an embodiment, the first RRC signaling or the second RRC signaling includes at least one of the following information: an RRC signaling combination, a validity time of the RRC signaling combination, and an arrangement order of one or more RRC signals in the RRC signaling combination; wherein the RRC signaling combination includes one or more RRC signals. In an example, for the case that the first RRC signaling and the second RRC signaling include multiple RRC signals, the first RRC signaling and the second RRC signaling both include related information of the RRC signaling combination, such as the validity time and the arrangement order. In an example, the RRC signaling combination can also be understood as a predefined RRC signaling configuration mode. For example, the RRC signaling combination includes four RRC signals (RRC0, RRC1, RRC2, and RRC3), and one of the corresponding RRC signaling configuration modes can be: RRC1, RRC2, RRC0, RRC3; and another RRC signaling configuration mode can be: RRC0, RRC3, RRC1, RRC2. It can be understood that for different RRC signaling configuration modes, the arrangement order of one or more RRC signals in the corresponding RRC signaling combination is different. In an example, for the process that the first communication device activates the RRC signal in the RRC signal set based on the first activation condition, the first communication device can switch from one RRC signaling configuration mode to another RRC signaling configuration mode based on the first activation condition. In an example, the RRC signaling combination includes multiple simplified RRC signals, and in the case of default RRC signal activation, the simplified RRC signals change according to the configured RRC signaling configuration mode. In an example, the RRC signaling combination includes a default RRC signal and a switching RRC signal, and the default RRC signal and the switching RRC signal change according to the configured RRC signaling configuration mode. In an example, when the RRC signaling configuration mode does not change, the RRC signals are activated in the order of the RRC signaling configuration mode in a cycle.

[0074] In an embodiment, the first activation condition is that the first communication device receives the first control signaling. In an example, upon the first communication device receiving the first control signaling, the first communication device activates one of the set of RRC signaling.

[0075] In an embodiment, the first control signaling comprises at least one of: Downlink Control Information (DCI) signaling; and Media Access Control-Control Element (MAC-CE) signaling.

[0076] In an embodiment, the first control signaling is DCI signaling, wherein the DCI signaling is non-scheduling DCI, or a redefinition of scheduling DCI. Optionally, the DCI signaling comprises non-scheduling DCI, such as scrambled with a new type of Radio Network Temporary Identity (RNTI), such as RRC-RNTI. Optionally, the DCI signaling comprises scheduling DCI, such as scheduling DCI redefinition, and is still scrambled with Configured Scheduling Radio Network Temporary Identifier (CS-RNTI), Cell Radio Network Temporary Identifier (C-RNTI), etc.: redefinition of fields such as HARQ-process number, TDRA, or FDRA. For example, the scheduling DCI adds a new bit field, which can be a reused bit field, such as some bits of the HARQ process number field, or a newly introduced bit field. One or more fields of the DCI are selected to indicate a codepoint in the set of RRC parameters, and the bitwidth of the field is greater than 1 only when the codepoint corresponds to an RRC parameter configuration.

[0077] In an embodiment, the first control signaling is DCI signaling, and the application delay of the DCI signaling is K0. Wherein K0 is an integer greater than 0. The parameters in the set of RRC parameters need to take effect within K0 units of time after the DCI activation, wherein K0 is defined as application delay, and K0 units include symbol, slot, millisecond, and HPID, etc. For example, the DCI activation time is the nth slot, and the DCI indicates the effective time as n+K0, and the K0 unit is slot.

[0078] In an embodiment, the first control signaling is DCI signaling, and the RRC signaling selected by the last DCI is used until the next switch DCI signaling is received.

[0079] In an embodiment, the first control signaling comprises configuration information of the RRC signaling to be activated; wherein the configuration information of the RRC signaling to be activated comprises at least one of: the RRC signaling to be activated; an identifier of the RRC signaling to be activated; a validity time of the RRC signaling to be activated; an enable indication of the RRC signaling to be activated; a deactivation indication of the RRC signaling to be activated; and a parameter in the RRC signaling to be activated. The RRC signaling to be activated refers to the RRC signaling or the combination of RRC signaling that needs to be switched; for example, the RRC signaling to be activated can comprise the first RRC signaling or the second RRC signaling. The identifier of the RRC signaling to be activated refers to the identification information of the RRC signaling that needs to be activated; for example, the identifier of the RRC signaling to be activated can comprise a code point or an index, etc., and optionally, one code point corresponds to one RRC signaling. Optionally, one index corresponds to one RRC signaling. Optionally, the correspondence between the code point or the index and the RRC signaling is predefined by a higher layer parameter. For example, in a set of RRC signaling comprising four RRC signaling, four code points of ‘00’, ‘01’, ‘10’, and ‘11’ correspond to RRC signaling 0, RRC signaling 1, RRC signaling 2, and RRC signaling 3, respectively. The indication domain of the first control signaling corresponds to 2 bits, and when the indication is ‘01’, it means that the RRC signaling 1 is activated and other RRC signaling is deactivated. The validity time of the RRC signaling to be activated refers to the time period within which the RRC signaling that needs to be switched is valid after receiving the first control signaling; for example, if the validity time of the RRC signaling to be activated is 5 ms, the first communication device is valid within 5 ms after receiving the first control signaling. Optionally, the validity time can be indicated by a code point or an index. For example, four code points of ‘00’, ‘01’, ‘10’, and ‘11’ correspond to validity times of 1 ms, 5 ms, 10 ms, and 15 ms, respectively. The indication domain of the first control signaling corresponds to 2 bits, and when the indication is ‘01’, it means that the validity time of the RRC signaling to be activated is 5 ms and the RRC signaling to be activated is activated. Optionally, the validity time can directly indicate a specific value. For example, the indication domain of the first control signaling corresponds to 4 bits, which can indicate any integer value from 0 to 15 ms. When the indication is ‘0101’, it means that the validity time of the RRC signaling to be activated is 5 ms and the RRC signaling to be activated is activated. In an example, the enable indication of the RRC signaling to be activated is used to indicate the activation or deactivation of the RRC signaling to be activated; for example, in a set of RRC signaling comprising two RRC signaling, i.e., a first RRC signaling and a second RRC signaling, the enable indication of the RRC signaling is 1 bit.Optionally, when the to-be-activated RRC signaling is the first RRC signaling, the to-be-activated RRC signaling enable indication is 0, indicating that the second RRC signaling is activated; when the to-be-activated RRC signaling enable indication is 1, indicating that the first RRC signaling is activated; or, the to-be-activated RRC signaling enable indication is 0, indicating that the first RRC signaling is activated; when the to-be-activated RRC signaling enable indication is 1, indicating that the second RRC signaling is activated; optionally, when the to-be-activated signaling is the second RRC signaling, the to-be-activated RRC signaling enable indication is 0, indicating that the first RRC signaling is activated; when the to-be-activated enable indication is 1, indicating that the second RRC signaling is activated, or, the to-be-activated RRC signaling enable indication is 0, indicating that the second RRC signaling is activated; when the to-be-activated RRC signaling enable indication is 1, indicating that the first RRC signaling is activated. In an example, the to-be-activated RRC signaling enable indication is used to indicate the activation or deactivation of the to-be-activated RRC signaling. For example, two RRC signaling are included in the RRC signaling set, i.e., a first RRC signaling and a second RRC signaling. Optionally, the first RRC signaling is in an activated state, and the second RRC signaling is determined to be in an activated state by the to-be-activated RRC signaling enable indication. Specifically, when the to-be-activated RRC signaling enable indication is '1', the second RRC signaling is activated; when the to-be-activated RRC signaling enable indication is '0', the second RRC signaling is deactivated or not activated, or, when the to-be-activated RRC signaling enable indication is '0', the second RRC signaling is activated; when the to-be-activated RRC signaling enable indication is '1', the second RRC signaling is deactivated or not activated. The to-be-activated RRC signaling enable indication is used to indicate the deactivation of the activated RRC signaling, for example, when the to-be-activated RRC signaling is the first RRC signaling, the deactivation to-be-activated RRC signaling enable indication is 0, indicating that the first RRC signaling is used; when the deactivation to-be-activated RRC signaling enable indication is 1, indicating that the second RRC signaling is used. The parameters in the to-be-activated RRC signaling refer to the configuration parameters of one or more RRC signaling that the first communication device needs to activate. In an example, the RRC signaling corresponds to the configuration parameters of the RRC signaling, for example, when the RRC signaling includes a grant scheduling signaling used to configure a non-dynamically scheduled uplink transmission, the corresponding configuration parameters at least include one of the following: a periodicity parameter; an offset parameter; a time domain resource allocation; a frequency domain resource allocation; a modulation and coding strategy level. Details are described above, and will not be described here.

[0080] In an embodiment, the validity time of the RRC signaling or the combination of RRC signaling to be activated is related to at least one of the following parameters: a starting position of the validity time; a length of the validity time; an ending position of the validity time. In an example, the starting position of the validity time can be understood as the time when the RRC signaling or the combination of RRC signaling to be activated takes effect; the ending position of the validity time can be understood as the time when the RRC signaling or the combination of RRC signaling to be activated is invalid; and the length of the validity time can be understood as the duration of the validity of the RRC signaling or the combination of RRC signaling to be activated. In an example, the validity time of the RRC signaling or the combination of RRC signaling to be activated can be determined based on the starting position of the validity time and the length of the validity time, or based on the starting position of the validity time and the ending position of the validity time, or based on the length of the validity time and the ending position of the validity time.

[0081] In an embodiment, the starting position of the validity time includes one of the following: a K1th symbol after a last symbol of receiving the first control signaling; a K2th symbol after a first symbol of receiving the first control signaling; a Nth slot after a slot of receiving the first control signaling; wherein K1, K2 and N are integers greater than 0. In an example, K1 and K2 can be the same value or different values, which are not limited. Optionally, K1, K2 or N is 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10.

[0082] In an embodiment, the determination of the length of the validity time M includes one of the following: determined by a higher layer parameter; indicated by the first control signaling; the length unit of the validity time includes one of the following: a slot, a symbol, a transmission time interval, a millisecond, a second, a subframe or a radio frame; wherein M is an integer greater than or equal to 1. Optionally, M is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20.

[0083] In an embodiment, the slot includes at least one of the following: an uplink slot; a downlink slot; a flexible slot.

[0084] In an embodiment, the ending position of the valid time comprises one of the following: K1+M symbols after a last symbol of receiving the first control signaling; K2+M symbols after a first symbol of receiving the first control signaling; N+M time slots after a time slot of receiving the first control signaling; wherein K1 and K2 are both integers greater than or equal to 1. In an example, the starting position of the valid time is the K1th symbol after a last symbol of receiving the first control signaling, and correspondingly, the ending position of the valid time is K1+M symbols after the last symbol of receiving the first control signaling. In an example, the starting position of the valid time is the K2th symbol after a first symbol of receiving the first control signaling, and correspondingly, the ending position of the valid time is K2+M symbols after the first symbol of receiving the first control signaling. In an example, the starting position of the valid time is the Nth time slot after a time slot of receiving the first control signaling, and correspondingly, the ending position of the valid time is N+M time slots after the time slot of receiving the first control signaling.

[0085] In an embodiment, the first activation condition is that an activated RRC signaling reaches a preconfigured time point; wherein the activated RRC signaling comprises: the first RRC signaling or the second RRC signaling. In an example, the activated RRC signaling can also be understood as the RRC signaling currently adopted by the first communication device. In the case that the duration of the first communication device adopting one RRC signaling reaches a preconfigured time point, the first communication device can activate other RRC signaling in the RRC signaling set. In an example, the other RRC signaling activated by the first communication device can be an RRC signaling different from the signaling of the activated RRC signaling.

[0086] In an embodiment, the first RRC signaling and the second RRC signaling respectively correspond to a preconfigured time point. In an example, there is a preconfigured time point for each RRC signaling in the RRC signaling set, i.e., the first RRC signaling and the second RRC signaling in the RRC signaling set respectively correspond to a preconfigured time point. In an example, the preconfigured time points respectively corresponding to the first RRC signaling and the second RRC signaling can be the same or different, which is not limited. In an example, in the case that the first RRC signaling or the second RRC signaling comprises an RRC signaling combination, the preconfigured time points respectively corresponding to each RRC signaling in the RRC signaling combination can be the same or different.

[0087] In an embodiment, the preconfigured time point comprises one of the following: a starting effective time point of the RRC signaling; an effective time length of the RRC signaling; a terminal effective time point of the RRC signaling; wherein the unit of the preconfigured time point comprises one of the following: time slot, symbol, transmission time interval, millisecond, second, subframe or radio frame.

[0088] Specifically, the RRC signaling set is used to configure the grant scheduling of the non-dynamic scheduling uplink transmission, and each RRC signaling contains its activation time point setting. For example, the switching and / or duration parameters are added in the default RRC signaling (first RRC signaling) and switching RRC signaling (second RRC signaling). The switching is in units of slots, etc.

[0089] For example, each RRC signaling in the RRC signaling set includes an activation time point, which is based on the activation time of the ConfiguredGrantConfig parameter set or the switching time point of the last configuration in the parameter set. The activation time point of each RRC signaling to the activation time point of the next RRC signaling is the activation time of the RRC signaling. The last item of the RRC signaling set is the default RRC parameter, which contains the activation time point and the duration. For example, the ConfiguredGrantConfigList in the default RRC signaling and the switching RRC signaling in the RRC signaling set contains 4 ConfiguredGrantConfigQck, which are ConfiguredGrantConfigQck0, ConfiguredGrantConfigQck1, ConfiguredGrantConfigQck2 and ConfiguredGrantConfigQck3 respectively. The corresponding switching parameters are 5, 10, 15 and 20 respectively.

[0090] The first slot after the activation of the RRC signaling set switches to the ConfiguredGrantConfigQck0 configuration, and at the fifth slot, the ConfiguredGrantConfigQck0 configuration switches to the ConfiguredGrantConfigQck1 configuration; at the 10th slot, the ConfiguredGrantConfigQck1 configuration switches to the ConfiguredGrantConfigQck2 configuration; at the 15th slot, the ConfiguredGrantConfigQck2 configuration switches to the ConfiguredGrantConfigQck3 configuration. The activation time period of ConfiguredGrantConfigQck3 is 5 slots. Then after the 20th slot, it switches back to the ConfiguredGrantConfigQck0 configuration.

[0091] For example, each RRC signaling combination (predefined configuration pattern) contains its switching time point setting. For example, add parameter switching and / or validity time period duration parameter in the predefined configuration pattern.

[0092] Each RRC signaling combination includes a validity time point, which is based on the validity time of the RRC signaling combination of the ConfiguredGrantConfig or based on the validity time period of the last configuration pattern in the RRC signaling combination. The validity time of each RRC signaling combination is between the validity time point of the RRC signaling combination and the validity time point of the next RRC signaling combination. The last item of the RRC signaling set is the default RRC signaling combination, which contains the validity time point and the duration. For example, the RRC signaling set ConfiguredGrantConfigPatternList contains 2 RRC signaling combinations CGPatternQck, and the RRC signaling combination CGPatternQck contains 4 grant scheduling configurations, whose IDs are 0, 1, 2, and 3, respectively.

[0093] The first time slot after the validity of the RRC signaling combination switches to the configuration of CGPatternQck0, and at the twentieth time slot, the configuration of CGPatternQck0 switches to the configuration of CGPatternQck1. The validity time period of CGPatternQck1 is 20 time slots. Then, after the 40th time slot, it switches back to the configuration of CGPatternQck0.

[0094] After the validity time of a certain RRC configuration parameter ends, it needs to fall back to the default RRC signaling. (Another RRC parameter is used to configure the RRC validity time period, period, offset, etc.)

[0095] In an embodiment, the switching time point can be obtained based on prediction information and movement trajectory information.

[0096] Specifically, the RRC signaling set is used to configure the physical downlink control channel monitoring occasion, and each RRC signaling contains its activation time point setting. For example, add parameter switching and / or validity time period duration parameter in the default RRC signaling (first RRC signaling) and switching RRC signaling (second RRC signaling). Wherein, Switching is in units of time slots, etc.

[0097] For example, each of the RRC signaling in the RRC signaling set includes an effective time point, which is based on the effective time of the ControlResourceSet parameter set or based on the switching time point of the last configuration in the parameter set. The effective time of each RRC signaling is between the effective time point of the RRC signaling and the effective time point of the next RRC signaling. The last item of the RRC signaling set is the default RRC signaling, which includes an effective time point and a duration. For example, in the RRC signaling set, the ControlResourceSetToAddModListQck in the default RRC signaling and the switching RRC signaling includes 4 controlResourceSetToAddModList, which are ControlResourceSetToAddModList0, ControlResourceSetToAddModList1, ControlResourceSetToAddModList2 and ControlResourceSetToAddModList3. The corresponding switching parameters are 5, 10, 15 and 20, respectively.

[0098] The first time slot after the RRC signaling set takes effect switches to the configuration of ControlResourceSetToAddModList0, and at the fifth time slot, the configuration of ControlResourceSetToAddModList0 switches to the configuration of ControlResourceSetToAddModList1; at the tenth time slot, the configuration of ControlResourceSetToAddModList1 switches to the configuration of ControlResourceSetToAddModList2; at the fifteenth time slot, the configuration of ControlResourceSetToAddModList2 switches to the configuration of ControlResourceSetToAddModList3. The effective time period of ControlResourceSetToAddModList3 is 5 time slots. Then after the twentieth time slot, it switches back to the configuration of ControlResourceSetToAddModList0.

[0099] For example, the RRC signaling combination (predefined configuration mode) includes the switching time point setting. For example, the predefined configuration mode includes the switching parameter and / or the effective time period duration parameter.

[0100] Each RRC signaling combination includes an effective time point, which is based on the effective time point of the RRC signaling combination of the ControlResourcesSet or based on the effective time period of the last configured pattern in the RRC signaling combination. The effective time of each RRC signaling combination is between the effective time point of each RRC signaling combination and the effective time point of the next RRC signaling combination. The last item of the RRC signaling set is the default RRC signaling combination, which includes an effective time point and a duration. For example, there are two signaling combinations CORESETPatternQck in the RRC signaling CORESETPatternList, and the RRC signaling combination CORESETPatternQck includes four CORESET configurations, whose IDs are 0, 1, 2, and 3, respectively.

[0101] The first time slot after the RRC signaling combination takes effect switches to the CORESETPatternQck0 configuration. At the twentieth time slot, the configuration of CORESETPatternQck0 switches to the configuration of CORESETPatternQck1. The effective time period of CORESETPatternQck1 is 20 time slots. After the 40th time slot, the configuration switches back to the CORESETPatternQck0 configuration.

[0102] After the effective time of a certain RRC configuration parameter ends, the default RRC needs to be switched back. (Another RRC parameter is used to configure the RRC effective time period, period, offset, etc.)

[0103] The switching time point can be obtained based on prediction information and movement trajectory information.

[0104] In an embodiment, the first activation condition is that the service awareness information changes; wherein the changed service awareness information comprises at least one of the following: synchronization indication information; synchronization data stream indication information; service type information; prediction information; and control signaling configuration information expected by the user equipment. The synchronization indication information is used to represent the time range of arrival of different Quality of Service (QoS) data streams, for example, the time interval for successful reception of a haptic data stream and a visual data stream is not greater than 15 ms. The synchronization data stream indication information is used to represent the indication information of different data streams that need to be synchronized. For example, the synchronization data stream indication information is 1-bit information, when the synchronization data stream indication information is ‘1’ or ‘true’, it indicates that the current data stream needs to be synchronized, or when the synchronization data stream indication information is ‘0’ or ‘false’, it indicates that the current data stream does not need to be synchronized. Alternatively, the synchronization data stream indication information is greater than 1-bit information. When the synchronization data stream indication information is 2-bit information, there are 4 states in total, wherein the ‘00’ state indicates that synchronization is not needed, and the same state indicates that two data streams need to be synchronized, for example, if the synchronization data stream indication information of two data streams is ‘10’, it indicates that the two data streams need to be synchronized with each other. If the synchronization data stream indication information of one data stream is ‘01’ and the synchronization data stream indication information of another data stream is ‘10’, the two data streams need to be synchronized, but the two data are not related, i.e. they do not synchronize with each other. The service type information is used to distinguish the service type information of different data streams, for example, different service type information corresponds to different indexes, and the service type is indicated by reporting the index, wherein the correspondence between the service type information and the index is determined by a higher layer parameter, such as a parameter in RRC signaling. The prediction information is used to predict the arrival information, service type information or service data packet size information of the service through artificial intelligence network. In an example, in the case that the service awareness information of the first communication device changes, the first communication device activates one of the RRC signaling sets.

[0105] In an embodiment, the service awareness information is transmitted through at least one of the following: user side header or data packet in General Packet Radio Service Tunneling Protocol; MAC-CE signaling; uplink control information; and UE auxiliary information.

[0106] In an embodiment, at a first time point after the service awareness information changes from a first value to a second value, the to-be-activated RRC signaling is activated; wherein the first time point is determined by an application delay; and the application delay is the time interval between the time when the first communication device reports the service awareness information and the activation time of the to-be-activated RRC signaling.

[0107] In an example, the first activation condition is that the current service awareness information changes: one, the downlink XR awareness information such as the downlink service arrival prediction information or the service periodicity information obtained from the core network side triggers the RRC configuration matched with the XR awareness information; two, the uplink XR awareness information such as the uplink service arrival prediction information or the service periodicity information obtained from the first communication node side triggers the RRC configuration matched with the XR awareness information.

[0108] Optionally, the XR awareness information (Downlink and uplink) includes: synchronization information; prediction information; service periodicity information; service jitter information; QoS parameters of a packet data unit set (PDU set); PDU set sequence number; PDU set packet size; sequence number of a PDU in the PDU set; end PDU indication of the PDU set; importance information of the PDU set.

[0109] In an embodiment, the first activation condition is that a transmission behavior of the first communication device changes; wherein the transmission behavior comprises one of: a transmission beam of the first communication device changes; a transmission reception point of the first communication device changes; an abnormal situation occurs; a serving cell of the first communication device reselects or switches; a transmission carrier of the first communication device changes; a transmission Hybrid Automatic Repeat Request (HARQ) Process ID (HPID) of the first communication device changes. In an example, in a case that a transmission beam currently adopted by the first communication device fails, a beam switch is needed, and different RRC signaling in the set of RRC signaling corresponds to different transmission beam, after the beam switch, the first communication device can switch the RRC signaling without performing RRC reconfiguration procedure, reducing configuration or scheduling delay. In an example, in a case that a transmission reception point currently adopted by the first communication device changes, and different RRC signaling in the set of RRC signaling corresponds to different transmission reception point, after the transmission reception point changes, the first communication device can switch the RRC signaling. In an example, the serving cell of the first communication device refers to a cell in which the first communication device currently performs data transmission or other behaviors; different RRC signaling in the set of RRC signaling corresponds to different cell, in a case that the serving cell of the first communication device needs to reselect or switch, the RRC signaling is switched. In an example, different RRC signaling in the set of RRC signaling corresponds to different transmission carrier, in a case that the transmission carrier of the first communication device switches, the corresponding RRC signaling also needs to switch. In an example, different RRC signaling in the set of RRC signaling corresponds to different HPID, in a case that the transmission HPID currently adopted by the first communication device changes, the corresponding RRC signaling also needs to switch.

[0110] In an embodiment, the beam failure includes one of the following: a measurement quantity measured by the first communication device is lower than a predefined threshold in a predefined time interval; the second communication device does not receive feedback information in a predefined time interval; the second communication device does not receive a predefined uplink transmission; the first communication device reports beam failure information; a transmission beam of the first communication device changes. In an example, the measurement quantity measured by the first communication device can be a value of a channel state information reference signal measured by the first communication device. In the case that the measurement quantity measured by the first communication device is lower than the predefined threshold in the predefined time interval, the first communication device has a downlink beam failure case and needs to perform beam switching; in the case that the second communication device does not receive the feedback information of the first communication device in the predefined time interval, the second communication device has a downlink beam failure and needs to perform beam switching; in the case that the second communication device does not receive the predefined uplink transmission, the second communication device has an uplink beam failure case and needs to perform beam switching; in the case that the first communication device reports the beam failure information, the first communication device has a downlink beam failure case and needs to perform beam switching; each transmission beam is configured with an RRC signaling, and when the transmission beam currently served by the first communication device changes, the first communication device can switch from one RRC signaling to another RRC signaling.

[0111] In an embodiment, the transmission beam of the first communication device includes: a first beam or a second beam; the second communication device configures the first RRC signaling for the first beam and configures the second RRC signaling for the second beam; in the case that the transmission beam of the first communication device switches from the first beam to the second beam, the first communication device activates the second RRC signaling. In an example, different beams are distinguished by beam indexes.

[0112] Example one, the transmission behavior includes different beam transmission (based on different precoding transmission): one, a set of RRC signaling can be used on different beams on the same carrier for grant scheduling of uplink transmission of non-dynamic scheduling, one RRC signaling (one or more first RRC signaling) in one beam corresponds to the RRC signaling set, and another RRC signaling (one or more second RRC signaling) in another beam corresponds to another RRC signaling set; two, different RRC parameter sets are used on different beams on the same carrier for grant scheduling of uplink transmission of non-dynamic scheduling.

[0113] For example, when the second communication node configures two RRC signaling (or two RRC signaling sets), in the case of beam failure, the switching mode of the beam failure is:

[0114] A. Switching mode 1: Two different ConfiguredGrantConfig configurations (or numerology configurations) are configured in one beam respectively. When the beam failure condition occurs, the first ConfiguredGrantConfig configuration (or numerology configuration) is used. When the beam failure condition does not occur, the second ConfiguredGrantConfig configuration (or numerology configuration) is used.

[0115] The beam failure (Beam failure) condition includes: downlink beam failure condition; the CSI-RS measured by the first communication node is lower than the predefined threshold within the predefined time interval.

[0116] The base station does not receive the feedback from the first communication node within the predefined time interval, such as ACK / NACK feedback of the predefined downlink transmission.

[0117] The base station does not receive the predefined uplink transmission.

[0118] The first communication node reports the beam failure (beam failure) information.

[0119] B. Beam recovery (Beam recovery) switching mode 1: Two different ConfiguredGrantConfig configurations (or numerology configurations) are configured in one beam. In the case where the base station configures a predefined downlink beam, under preset condition 1, the first ConfiguredGrantConfig configuration (or numerology configuration) is used. Under preset condition 2, the second ConfiguredGrantConfig configuration (or numerology configuration) is used.

[0120] The base station configures a predefined downlink beam, which means that the base station configures a "backup" beam to cope with the beam failure condition. If a beam fails, the base station can directly use the backup beam for transmission.

[0121] The preset condition 1 includes: the channel state information (such as Channel Quality Indicator (CQI) information, Signal to Interference plus Noise Ratio (SINR) information, Reference Signal Receiving Power (RSRP) information and Reference Signal Receiving Quality (RSRQ) information, etc.) in the current beam meets the preset threshold value.

[0122] Precondition 2 includes that the channel state information (such as CQI information, SINR information, RSRP information, and RSRQ information) in the current beam meets a preset threshold value.

[0123] C. Beam recovery switching mode 2: two different ConfiguredGrantConfig configurations (or parameter set configurations) are configured in one beam respectively. In the case where the base station does not configure a predefined downlink beam, in the case of precondition 1, the first ConfiguredGrantConfig configuration (or RRC signaling set configuration) is used. In the case of precondition 2, the second ConfiguredGrantConfig configuration (or RRC signaling set configuration) is used.

[0124] Precondition 1 includes:

[0125] Beam not recovered (gNB configures PUCCH, data, SRS for uplink transmission. Used for fast recovery of beam.)

[0126] Beam not recovered (gNB configures PRACH for uplink transmission, and performs beam recovery.)

[0127] Precondition 2 includes:

[0128] Beam has been recovered.

[0129] Example two, the transmission behavior includes different beam transmission (based on different precoding transmission): first, a set of CORESET / searchSpace RRC signaling set on different beams on the same carrier can be used to configure physical downlink control channel monitoring occasions, wherein one beam corresponds to one or more first RRC signals in the RRC signaling set. Another beam corresponds to another RRC signaling (one or more second RRC signals) in the RRC signaling set; second, different RRC parameter sets on different beams on the same carrier are used to configure physical downlink control channel monitoring occasions.

[0130] For example, when the second communication node configures two RRC signals (or two RRC signaling sets), the switching mode of beam failure occurs when the beam fails:

[0131] A. Switching mode 1: Two different CORESET configurations and PDCCH MO configurations (or RRC signaling combined configuration) are configured in one beam respectively. When the beam failure condition occurs, the first CORESET configuration and PDCCH MO configuration (or RRC signaling combined configuration) are used. When the beam failure condition does not occur, the second CORESET configuration and PDCCH MO configuration (or RRC signaling combined configuration) are used.

[0132] Wherein, the beam failure (Beam failure) condition includes: downlink beam failure condition; the CSI-RS measured by the first communication node is lower than the predefined threshold within the predefined time interval.

[0133] The base station does not receive the feedback from the first communication node within the predefined time interval, such as not receiving the ACK / NACK feedback of the predefined downlink transmission.

[0134] The base station does not receive the predefined uplink transmission.

[0135] The first communication node reports the beam failure (beam failure) information.

[0136] B. Beam recovery (Beam recovery) switching mode 1: Two different CORESET configurations and PDCCH MO configurations (or RRC signaling combined configuration) are configured in one beam. In the case of the base station configuring a predefined downlink beam, in the case of preset condition 1, the first CORESET configuration and PDCCH MO configuration (or RRC signaling combined configuration) are used. In the case of preset condition 2, the second CORESET configuration and PDCCH MO configuration (or RRC signaling combined configuration) are used.

[0137] Wherein, the base station configures a predefined downlink beam, which means that the base station configures a "backup" beam to cope with the beam failure condition. If a beam fails, the base station can directly use the backup beam for transmission.

[0138] Preset condition 1 includes: the channel state information (such as CQI information, SINR information, RSRP information and RSRQ information, etc.) in the current beam meets the preset threshold value.

[0139] Preset condition 2 includes: the channel state information (such as CQI information, SINR information, RSRP information and RSRQ information, etc.) in the current beam meets the preset threshold value.

[0140] C. Beam recovery switching mode 2: two different CORESET configurations and PDCCH MO configurations (or RRC signaling combination configurations) are configured in one beam. In the case of a pre-defined downlink beam not configured by the base station, under preset condition 1, the first CORESET configuration and PDCCH MO configuration (or RRC signaling combination configuration) are used. In the case of preset condition 2, the second CORESET configuration and PDCCH MO configuration (or RRC signaling combination configuration) are used.

[0141] The preset condition 1 includes:

[0142] Beam not recovered (gNB configures PUCCH, data, SRS for uplink transmission. Used for fast recovery of beam.)

[0143] Beam not recovered (gNB configures PRACH for uplink transmission, and performs beam recovery.)

[0144] The preset condition 2 includes:

[0145] Beam has been recovered.

[0146] Example three, the transmission behavior includes different beam transmission (based on different precoding transmission): first, a set of RRC signaling sets on different beams on the same carrier can be used for measurement set configuration, wherein one RRC signaling (one or more first RRC signaling) in the RRC signaling set in one beam indicates the configuration of one or more measurement sets, and another RRC signaling (one or more second RRC signaling) in the RRC signaling set in another beam indicates the configuration of one or more measurement sets; second, different RRC parameter sets are used for measurement set configuration on different beams on the same carrier.

[0147] In an embodiment, the transmission reception point of the first communication device includes a first transmission reception point and a second transmission reception point; the second communication device configures the first RRC signaling for the first transmission reception point, and configures the second RRC signaling for the second transmission reception point; in the case that the transmission reception point of the first communication device is changed from the first transmission reception point to the second transmission reception point, or in the case that the transmission reception point of the first communication device needs to add the second transmission reception point, the first communication device activates the second RRC signaling.

[0148] In an example, the transmission behavior includes different transmission and receive points (TRPs): one, a set of RRC signaling is used on different TRPs, for grant scheduling of uplink transmission without dynamic scheduling, for configuring physical downlink control channel monitoring occasions, for configuring measurement sets, or, for configuring, wherein one RRC signaling (one or more first RRC signaling) in the set of RRC signaling is used on one TRP, and another RRC signaling (one or more second RRC signaling) in the set of RRC signaling is used on another TRP; two, different sets of RRC parameters are used on different TRPs, for grant scheduling of uplink transmission without dynamic scheduling, for configuring physical downlink control channel monitoring occasions, for configuring measurement sets.

[0149] In an embodiment, the abnormal case includes one of the following cases: a data packet loss satisfies a predefined data packet loss threshold; a channel state information measurement does not satisfy a predefined measurement threshold. In an example, the data packet loss can be represented as a data packet loss quantity, or as a data packet loss rate; correspondingly, the predefined data packet loss threshold corresponding to the data packet loss can include a data packet loss quantity threshold and a data packet loss rate threshold. In an example, the second communication device configures a first RRC signaling for a normal case, and configures a second RRC signaling for an abnormal case. In a case where the data packet loss quantity reaches the data packet loss quantity threshold, or the data packet loss rate reaches the data packet loss rate threshold, it indicates that the first communication device is in an abnormal case, and the first communication device activates the second RRC signaling; in a case where the data packet loss quantity does not reach the data packet loss quantity threshold, or the data packet loss rate does not reach the data packet loss rate threshold, it indicates that the first communication device is in a normal case, and the first communication device activates the first RRC signaling. In an example, the channel state information measurement refers to a result of measuring a state of a communication channel used by the first communication device. In a case where the channel state information measurement does not satisfy the predefined measurement threshold, it indicates that the first communication device is in an abnormal case, and the first communication device activates the first RRC signaling; in a case where the channel state information measurement satisfies the predefined measurement threshold, it indicates that the first communication device is in a normal case, and the first communication device activates the second RRC signaling.

[0150] In an embodiment, the second communication device configures the second RRC signaling for an abnormal case; and the first communication device activates the second RRC signaling in a case where the abnormal case occurs.

[0151] In an embodiment, the service cell reselection or handover of the first communication device to the first cell, or to the second cell, comprises one of the following: reselection or handover of the cell with the first physical cell identity to the cell with the second physical cell identity; reselection or handover of the cell with the first cell identity to the cell with the second cell identity; reselection or handover of the first active area to the second active area; transformation of the first transmission configuration indicator state to the second transmission configuration indicator state. In an example, the active area comprises one or more cells. For example, the cell comprises a micro cell, a super cell, a cellular cell. In an example, the second communication device can configure different RRC signaling for different physical cell identities (PCI), or for different cell identities, or for different active areas, or for different transmission configuration indicator (TCI) states. In the case that the currently adopted physical cell identity of the first communication device is reselected or handed over from the first physical cell identity to the second physical cell identity, or the currently adopted first cell identity is handed over to the second cell identity, or the currently adopted first active area is handed over to the second active area, or the currently adopted first transmission configuration indicator state is handed over to the second transmission configuration indicator state, the first communication device can perform handover or activation of the RRC signaling.

[0152] In an embodiment, the second communication device configures the first RRC signaling for the first cell, and configures the second RRC signaling for the second cell; in the case that the service cell of the first communication device is reselected or handed over from the first cell to the second cell, the first communication device activates the second RRC signaling.

[0153] In an example, the transmission behavior comprises different cell (Cell) transmission: one, different PCI cells can adopt a set of RRC signaling for non-dynamic scheduling of uplink transmission authorization scheduling, which needs to group the PCIs adopting the same RRC signaling set, for example, PCI = {0, 1, 2, 3} is a group, corresponding to the RRC signaling (one or more first RRC signaling) in the RRC signaling set, PCI = {4, 5, 6, 7} is another group, corresponding to another RRC signaling (one or more second RRC signaling) in the RRC signaling; two, different PCIs can adopt different RRC signaling sets for non-dynamic scheduling of uplink transmission authorization scheduling.

[0154] For example, when the second communication node configures two RRC signaling (or two RRC signaling sets), the following switching modes are included:

[0155] A. Cell reselection switching mode 1: two different ConfiguredGrantConfig configurations are configured for two different cells. When the reselection is not completed, i.e. the serving cell of the first communication node has not been changed, the ConfiguredGrantConfig configuration of the current serving cell is used. When the reselection is completed, i.e. the serving cell of the first communication node has been changed, the ConfiguredGrantConfig configuration of the target serving cell is used.

[0156] B. Cell reselection switching mode 2: two different ConfiguredGrantConfig configurations (or RRC signaling combined configuration) exist in two cells respectively. When the terminal device meets the cell switching condition, the first communication node uses the first ConfiguredGrantConfig configuration (or RRC signaling combined configuration) in the current serving cell. When the terminal device does not meet the cell switching condition, the first communication node uses the second ConfiguredGrantConfig configuration in the current serving cell.

[0157] The switching condition includes that the first communication node measures the RSRQ, RSRP or SINR of the neighbor cell to be higher than a predefined threshold.

[0158] The reselection not completed condition includes that the first communication node measures the RSRQ, RSRP or SINR of the neighbor cell to be higher than a predefined threshold, but the PLMN information in the current UE has not been changed, i.e. currently in the selection of the target switching cell, or the first communication node is in the reselection request stage.

[0159] C. Cell reselection switching mode 3: two different ConfiguredGrantConfig configurations (or RRC signaling set configuration) exist in two cells respectively. When the terminal device switches to the target serving cell, when the preset condition 1 is met, the UE uses the first ConfiguredGrantConfig configuration. When the preset condition 2 is met, the UE uses the second ConfiguredGrantConfig configuration.

[0160] The preset condition 1 includes that:

[0161] The first communication node measures the RSRQ, RSRP or SINR of the current cell to be higher than a predefined threshold.

[0162] The preset condition 2 is a mutually exclusive event of the preset condition 1, i.e.:

[0163] The first communication node measures RSRQ, RSRP or SINR of the current cell to be no less than a predefined threshold.

[0164] In an example two, the transmission behavior includes different cell (Cell) transmission: one, different PCIs of cells can adopt a set of RRC signaling set for configuring physical downlink control channel monitoring occasions, and the PCIs adopting the same RRC signaling set need to be grouped, for example, PCIs = {0, 1, 2, 3} are a group, corresponding to one or more first RRC signals in the RRC signaling set, and PCIs = {4, 5, 6, 7} are another group, corresponding to another RRC signal (one or more second RRC signals) in the RRC signaling; two, different PCIs can adopt different RRC signaling sets for configuring physical downlink control channel monitoring occasions.

[0165] Cell reselection switching mode 1: different COREST configurations and PDCCH monitoring occasion configurations are configured for two different cells. When the reselection is not completed, that is, the service cell of the first communication node has not been changed, the CORESET and PDCCH monitoring configuration of the current service cell is used. When the reselection is completed, that is, the service cell of the first communication node has been changed, the CORESET and PDCCH monitoring configuration of the target service cell is used.

[0166] Cell reselection switching mode 2: two different CORESET configurations and PDCCH MO configurations (or RRC signaling combination configurations) exist in two cells respectively. When the terminal device meets the cell switching condition, the first communication node uses the first CORESET configuration and PDCCH MO configuration (or RRC signaling combination configuration) in the current service cell. When the terminal device does not meet the cell switching condition, the first communication node uses the second CORESET configuration and PDCCH MO configuration in the current service cell.

[0167] The switching condition includes:

[0168] The first communication node measures RSRQ, RSRP or SINR of the neighbor cell to be higher than a predefined threshold.

[0169] The reselection not completed condition includes:

[0170] The first communication node measures RSRQ, RSRP or SINR of the neighbor cell to be higher than a predefined threshold, but the PLMN information in the current first communication node has not been changed, that is, the current is in the selection of the target switching cell, or the UE reselection request stage.

[0171] Cell reselection switching mode 3: two cells respectively exist two different CORESET configurations and PDCCH MO configurations (or RRC signaling combined configurations). When the terminal device switches to the target service cell, when preset condition 1 is met, the UE uses the first CORESET configuration and PDCCH MO configuration. When preset condition 2 is met, the first communication node uses the second CORESET configuration and PDCCH MO configuration (or RRC signaling combined configuration).

[0172] Among them, the preset condition 1 includes:

[0173] The first communication node measures that the RSRQ, RSRP or SINR of the current cell is higher than the pre-defined threshold.

[0174] The preset condition 2 is the mutual exclusion event of the preset condition 1, that is:

[0175] The first communication node measures that the RSRQ, RSRP or SINR of the current cell is not lower than the pre-defined threshold.

[0176] Example three, the transmission behavior includes different cell (Cell) transmission: one, different PCI cells can use a set of RRC signaling set to configure a measurement set, and the PCIs using the same RRC signaling set need to be grouped, for example, PCI={0, 1, 2, 3} is a group, corresponding to the RRC signaling (one or more first RRC signaling) in the RRC signaling set, PCI={4, 5, 6, 7} is another group, corresponding to another RRC signaling (one or more second RRC signaling) in the RRC signaling; two, different PCIs can use different RRC signaling sets to configure measurement sets.

[0177] In an embodiment, the transmission carrier of the first communication device includes: a first carrier or a second carrier; the second communication device configures the first RRC signaling for the first carrier, and configures the second RRC signaling for the second carrier; in the case that the transmission carrier of the first communication device is changed from the first carrier to the second carrier, or the transmission carrier of the first communication device needs to add the second carrier, the first communication device activates the second RRC signaling.

[0178] In an example, the transmission behavior includes different carrier (Carrier) transmission: (1) different carriers can adopt a set of RRC signaling, for grant scheduling of non-dynamic scheduling uplink transmission, for configuring physical downlink control channel monitoring occasions, or for measurement set configuration. It is necessary to group the carriers adopting the same RRC signaling set, such as Carrier ID = {0, 1, 2, 3} for a group, corresponding to the RRC signaling (one or more first RRC signaling) in the RRC signaling set, Carrier ID = {4, 5, 6, 7} for another group corresponding to another RRC signaling (one or more second RRC signaling) in the RRC signaling set; (2) different carrier IDs can adopt different RRC signaling sets for grant scheduling of non-dynamic scheduling uplink transmission, for configuring physical downlink control channel monitoring occasions, for measurement set configuration.

[0179] In an embodiment, the transmission HPID of the first communication device includes: the first HPID or the second HPID; the second communication device configures the first RRC signaling for the first HPID, and configures the second RRC signaling for the second HPID; in the case that the transmission HPID of the first communication device changes from the first HPID to the second HPID, the first communication device activates the second RRC signaling.

[0180] In an embodiment, the transmission HPID of the first communication device can be grouped, including a first HPID group and a second HPID group. Each HPID group includes one or more HPIDs, the first HPID group is configured with the first RRC signaling, and the second HPID group is configured with the second RRC signaling; in the case that the transmission HPID of the first communication device changes from an HPID in the first HPID group to an HPID in the second HPID group, the first communication device activates the second RRC signaling.

[0181] In an example, the transmission behavior includes different bandwidth part (Bandwidth part, BWP) transmission: (1) different bandwidth parts can adopt the same RRC signaling set, for grant scheduling of non-dynamic scheduling uplink transmission, for configuring physical downlink control channel monitoring occasions, or for configuring measurement set, it is necessary to group the BWP IDs adopting the same RRC signaling set, such as BWP ID = {0, 1, 2, 3} for a group, corresponding to the RRC signaling (one or more first RRC signaling) in the RRC signaling set, BWP ID = {4, 5, 6, 7} for another group corresponding to another RRC signaling (one or more second RRC signaling); (2) different BWPs can adopt different RRC signaling sets for grant scheduling of non-dynamic scheduling uplink transmission, for configuring physical downlink control channel monitoring occasions, for configuring measurement set.

[0182] For example, the first activation condition is that the BWP of the first communication node changes, wherein the BWP switching mode comprises, optionally, switching through DCI format 0_1 of uplink, wherein a BWP-ID is indicated in the DCI format 0_1 to trigger the BWP switching. After the BWP switching, the corresponding RRC signaling or RRC signaling resource set changes; optionally, the BWP switching is performed through RRC reconfiguration / bwp-InactivityTimer, and the corresponding RRC signaling or RRC signaling resource set is switched after the switching; optionally, the BWP switching is performed through initiating a random access procedure in the configured UL BWP, and the corresponding RRC signaling or RRC signaling combination is switched after the switching.

[0183] For example, the second communication node configures two RRC signaling (or two RRC signaling sets), and the following switching modes exist:

[0184] A. BWP switching mode 1: a timer is defined, and the timer starts counting from the time when the BWP is activated. When the UE is in the current indicated BWP, if the time of the first communication node in the current BWP does not reach the time defined by the timer, one RRC parameter (for example, the first RRC signaling) is used. When the time of the first communication node in the current BWP reaches the time defined by the timer, another RRC parameter (for example, the first RRC signaling) is used.

[0185] B. BWP switching mode 2: a time window is defined, and when the UE is in the time window of the current BWP, one RRC parameter (for example, the first RRC signaling) is used. When the UE is not in the time window of the current BWP, another RRC parameter (for example, the second RRC signaling) is used.

[0186] C. BWP switching mode 3: an abnormal situation trigger is defined, and when the UE is in a normal situation, one RRC parameter (for example, the first RRC signaling) is used. When the UE is in an abnormal situation, another RRC parameter (for example, the second RRC signaling) is used.

[0187] In an embodiment, the first activation condition is that the first communication device sends the first information. In an example, in a case where the first communication device sends the first information to the second communication device, the first communication device activates or switches the RRC signaling based on the activation condition.

[0188] In an embodiment, the first information is carried through at least one of the following: uplink control information; a random access sequence; MAC-CE signaling; a sounding reference signal; and RRC signaling.

[0189] In an embodiment, the first information comprises one of: an index of the RRC signaling to be activated desired by the user equipment; an RRC signaling activation request information; a resource request information; a time instant of the RRC signaling activation request. In an example, the RRC signaling to be activated refers to the RRC signaling that needs to be activated or switched to; the RRC signaling to be activated can comprise a first RRC signaling or a second RRC signaling. In an example, the index of the RRC signaling to be activated indicates the corresponding RRC signaling to be activated, the correspondence between the index of the RRC signaling to be activated and the RRC signaling to be activated is determined by a higher layer parameter configuration. In an example, the RRC signaling activation request information indicates whether the first communication node needs or does not need feedback of the RRC signaling activation. For example, the RRC signaling activation request information is 1 bit, when the RRC signaling activation request information is ‘1’, the first communication node requests the RRC signaling to be activated, or when the RRC signaling activation request information is ‘0’, the first communication node does not request the RRC signaling to be activated, and vice versa. In an example, the resource request information comprises a scheduling request information or a buffer size information. In an example, the time instant of the RRC signaling activation request is a time instant when the first communication node expects the activation of the RRC signaling to be activated. The time instant of the RRC signaling activation request is represented as a time interval between the time instant of transmitting the first information and the time instant of activating the RRC signaling to be activated, the time interval unit comprises: a symbol, a slot, a transmission time interval, a subframe, a system frame, a millisecond, or a second. Alternatively, the time interval can be represented by a codepoint or an index, one codepoint or index corresponds to one time interval. For example, the time instant of the RRC signaling activation request comprises 2 bits, wherein ‘00’, ‘01’, ‘10’, ‘11’ four codepoints correspond to time intervals 1 ms, 5 ms, 10 ms, 15 ms respectively. When the codepoint ‘01’ is indicated, it means that the time instant of the RRC signaling to be activated is 5 ms after the current transmission of the first information.

[0190] In an embodiment, the first information is transmitted through at least one of the following channels: a physical uplink control channel; a physical uplink shared channel; a physical random access channel.

[0191] In an embodiment, the RRC signaling to be activated is associated with the channel of transmitting the first information.

[0192] In an embodiment, there is a predefined offset value between the time instant of activating the RRC signaling to be activated and the channel of transmitting the first information.

[0193] In an embodiment, the predefined offset value is determined by one of: indicated by the first information; determined by a higher layer parameter.

[0194] In an embodiment, FIG. 2 is a flowchart of another signaling switching method provided by embodiments of the present application. The embodiment is applied to the case of fast switching of RRC signaling in an immersive communication scenario. The embodiment can be executed by a second communication device. As shown in FIG. 2, the embodiment includes S210-S220.

[0239] In the following embodiments, the first communication device is taken as an example of UE, and the second communication device is taken as an example of a base station to describe the switching process of the RRC signaling.

[0240] Embodiment 1

[0241] In this embodiment, the switching process of the RRC signaling including the configuration signaling for Multiple Input Multiple Output (MIMO) is described.

[0242] Specifically, the configuration parameter switching of the MIMO RRC signaling can include: the maximum number of layers MaxMIMOLayer, the configuration MIMO-ParametersPerBand related to the MIMO parameter, including maxNumberActiveTCI-PerBWP, uplinkBeamManagement, etc.

[0243] Optionally, the fast switching process of the RRC signaling occurs when the UE is in an RRC connected state.

[0244] The configuration parameter of the RRC signaling is MaxMIMOLayer, and the switching parameter includes the maximum number of layers of PDSCH.

[0245] Specifically, the RRC layer configures a parameter set based on PDSCH-config, and the parameter set is composed of the following factors.

[0246] In an example, the parameter set composition includes the configuration of the default RRC signaling and the compact RRC signaling:

[0247] Among them, the default RRC signaling (such as PDSCH-config) is used to configure the configuration of PDSCH, which contains all possible maximum MIMO layer reference values at present.

[0248] The simplified RRC signaling is also used for configuring the PDCCH resource occupation. Unlike the default RRC signaling, the simplified RRC signaling only includes parameters that need to be quickly switched, such as only including the parameter maxMIMO-layers in the simplified RRC signaling.

[0249] For example, the configuration rule of the RRC parameter set: the basic PDSCH scheduling configuration parameters, except for the maxMIMO-layers, use the configuration parameters of the default RRC signaling. The parameters that need to be quickly switched use the periodic parameters indicated in the simplified RRC signaling. The final RRC signaling for the non-dynamic scheduling uplink transmission mode is configured by the configuration of the default RRC signaling and the simplified RRC signaling.

[0250] For example, the maxMIMO-layers in the default RRC signaling structure is deleted.

[0251] All the simplified RRC signaling forms a list (or other forms), and the parameter list structure of the simplified RRC signaling is added with maxMIMO-layers, for example.

[0252] Optionally, the parameter set configuration mode includes the configuration of the default RRC signaling and the switching RRC signaling:

[0253] The default RRC signaling is used for PDSCH resource configuration.

[0254] The switching RRC signaling is used for PDSCH resource configuration.

[0255] The configuration rule of the RRC parameter set: the default RRC signaling and the switching RRC signaling are numbered by introducing an index, and the PDCCH configuration time-frequency domain resource configuration of the RRC signaling is realized by selecting different numbers.

[0256] In the current protocol, the number of layers that the UE can receive can be configured in PDSCH-config through MaxMIMOlayer, and only one MIMOlayer number is included in each PDSCH-config configuration. In order to make the resource configuration more flexible and variable, the entries in the list are allowed to include a combination of multiple PDSCH IDs. For example, the content of the enhanced list is: PDSCH-config.

[0257] For example, the default RRC signaling structure and the switching RRC signaling structure both include at least maxMIMO-Layers-r16, which can be 1, 2, 4, or 8, for example.

[0258] In an example, the parameter set composition manner includes a pre-defined configuration mode, the pre-defined mode includes one or more default RRC signaling and compact RRC signaling, and the default RRC signaling and switching RRC signaling:

[0259] Based on the default RRC signaling and compact RRC signaling, or the default RRC signaling and switching RRC signaling, a mode of different values of the default RRC signaling and the compact RRC signaling is generated. For example, in the configuration of the default RRC signaling and the compact RRC signaling, there are four compact RRC signaling, respectively including four different time-frequency domain resource configurations, corresponding to IE1, IE2, IE3, and IE4. The default RRC signaling is IE0. The configured mode can be {IE0+IE3, IE0+IE1, IE0+IE4, IE0+IE2}, and these modes are encoded by codepoint.

[0260] For example, in the configuration of the default RRC signaling and the switching RRC signaling, there are five different configurations of RRC signaling, IE1, IE2, IE3, and IE4 are switching RRC signaling, and IE0 is the default RRC signaling. The configuration mode can be {IE0, IE3, IE1, IE4, IE2}, and these modes can be encoded by codepoint.

[0261] For example, in the above example, a list MIMOLayerSetPatternList can be added to save different configuration modes.

[0262] In an example, the RRC layer configures a parameter set based on SearchSpace.

[0263] Optionally, the parameter set composition manner includes the configuration of the default RRC signaling and the compact RRC signaling, which is similar to the parameter set composition manner of the above embodiment.

[0264] Optionally, the parameter set composition manner includes the configuration of the default RRC signaling and the switching RRC signaling, which is similar to the parameter set composition manner of the above embodiment.

[0265] Optionally, the parameter set composition manner includes a pre-defined configuration mode, which is similar to the parameter set composition manner of the above embodiment.

[0266] In an example, the RRC signaling has different configurations based on different transmission behaviors:

[0267] Example one, the transmission behavior includes different beam transmission (based on different precoding transmission)

[0268] a. Different beams on the same carrier can employ a set of PDSCH-config RRC signaling set, where one beam corresponds to one set of RRC signaling in the parameter set. Another beam corresponds to another set of RRC signaling in the parameter set

[0269] b. Different beams on the same carrier employ different PDSCH-config parameter sets.

[0270] Example two, transmission behavior includes different transmit and receive point (TRP) transmission

[0271] a. Different TRPs can employ a set of PDSCH-config RRC signaling set, where one TRP corresponds to one set of RRC signaling in the parameter set. Another TRP corresponds to another set of IE in the parameter set

[0272] b. Different TRPs can employ different PDSCH-config RRC signaling set.

[0273] Example three, transmission behavior includes different bandwidth part (BWP) transmission.

[0274] a. Different BWPs can employ the same PDSCH-config RRC signaling set, which requires grouping of BWP IDs that employ the same parameter set. For example, BWP IDs = {0, 1, 2, 3} are one group, and BWP IDs = {4, 5, 6, 7} are another group. Each group uses a different configuredGrantConfig parameter set.

[0275] b. Different BWPs can employ different PDSCH-config RRC signaling set.

[0276] Example four, transmission behavior includes different cell transmission.

[0277] a. Different physical carrier identifiers (PCIs) can employ the same PDSCH-config RRC signaling set. This requires grouping of PCIs that employ the same parameter set. For example, PCIs = {0, 1, 2, 3} are one group, and PCIs = {4, 5, 6, 7} are another group. Each group uses a different PDSCH-config RRC signaling set.

[0278] b. Different PCIs can employ different PDSCH-config RRC signaling set.

[0279] Example five, transmission behavior includes different carrier (Carrier) transmission.

[0280] a. Different carriers can use the same RRC signaling set of PDSCH-config. It is necessary to group the carriers that use the same parameter set. For example, Carrier ID = {0, 1, 2, 3} is a group, and Carrier ID = {4, 5, 6, 7} is another group. Each group uses a different RRC signaling set of PDSCH-config.

[0281] b. Different PCIs can use different RRC signaling sets of PDSCH-config.

[0282] Specifically, based on the parameter set of PDSCH-config, the content of RRC configuration fast switching includes:

[0283] Optionally, one switching mode is to switch through DCI signaling. (DCI signaling is non-scheduling DCI, which can be a redefinition of scheduling DCI)

[0284] Optionally, the DCI signaling includes non-scheduling DCI: using a new type of RNTI scrambling: such as RRC-RNTI scrambling (2)

[0285] Optionally, the DCI signaling includes scheduling DCI, such as scheduling DCI redefinition: still using CS-RNTI, C-RNTI, etc. Scrambling: redefining the HARQ-process number / TDRA / FDRA fields.

[0286] For example, the scheduling DCI adds a new bit field, which can be a reused bit field, such as using some bits of the HARQ process number field to indicate a new bit field, or a newly introduced bit field.

[0287] Select one or more fields of DCI to indicate the Codepoint in the RRC parameter set. When the RRC parameter configuration is corresponding, the bitwidth of the field is greater than 1.

[0288] When using DCI signaling to switch, the application delay of DCI is K0.

[0289] The parameters in the RRC parameter set need to take effect within X units of time after the DCI activation, where X is defined as the application delay. The DCI activation time is the nth slot. X units include symbols, slots, milliseconds, HPIDs, etc.

[0290] Switching by DCI signaling, all use the RRC signaling selected by the last DCI before receiving the next switching DCI signaling.

[0291] In an example, a switching mode is by configuring an effective time period duration.

[0292] a. Each RRC signaling configuration contains its switching time point setting. For example, add parameters switching and or effective time period duration parameters in the RRC signaling set of PDSCH-config.

[0293] Wherein, Switching is in units of slots, etc.

[0294] Each RRC signaling in the RRC signaling set of PDSCH-config includes an effective time point, which is based on the effective time of the RRC signaling of PDSCH-config or based on the switching time point of the last configuration in the parameter set. The effective time point of each RRC signaling to the effective time point of the next RRC signaling is the effective time of the RRC signaling. The last item in the parameter set is the default RRC signaling, which includes the effective time point and the duration. For example, 4 RRC signaling PDSCH-configToAddModList are included in the RRC signaling set of PDSCH-config, PDSCHToAddModListQck, as follows: PDSCH-configToAddModList0, PDSCH-configToAddModList1, PDSCH-configToAddModList2 and PDSCH-configToAddModList3.

[0295] The first slot after the RRC signaling set takes effect switches to the configuration of PDSCH-configToAddModList0, at the fifth slot, the configuration of PDSCH-configToAddModList0 switches to the configuration of PDSCH-configToAddModList1; at the 10th slot, the configuration of PDSCH-configToAddModList1 switches to the configuration of PDSCH-configToAddModList2; at the 15th slot, the configuration of PDSCH-configToAddModList2 switches to the configuration of PDSCH-configToAddModList3. The effective time period of PDSCH-configToAddModList3 is 5 slots. Then after the 20th slot, it switches back to the configuration of PDSCH-configToAddModList0.

[0296] b. Each RRC signaling configuration mode contains its switching time point setting. For example, MaxMIMOLayerPatternQck is added in MaxMIMOLayerPatternList, and switching and duration are added in MaxMIMOLayerPatternQck.

[0297] Each RRC signaling combination configuration in the MaxMIMOLayer parameter set includes an effective time point, which is based on the effective time of the maxNrofMMLPattern parameter set or based on the effective time period of the last configuration mode in the parameter set. The effective time of each RRC signaling is between the effective time point of the RRC signaling and the effective time point of the next RRC signaling. The last item in the parameter set is the default RRC signaling combination, which includes an effective time point and a duration. For example, two RRC signaling combinations MaxMIMOLayerPatternQck are included in the RRC signaling set MaxMIMOLayerPatternList, and there are four MIMO layer combination configurations in the RRC signaling combination MaxMIMOLayerPattern, whose IDs are 0, 1, 2, and 3, respectively.

[0298] The first time slot after the RRC parameter set takes effect switches to the MaxMIMOLayerPatternQck0 configuration, and at the twentieth time slot, the MaxMIMOLayerPatternQck0 configuration switches to the MaxMIMOLayerPatternQck1 configuration. The effective time period of the MaxMIMOLayerPatternQck1 configuration is 20 time slots. Then, after the 40th time slot, the MaxMIMOLayerPatternQck0 configuration is switched again.

[0299] The switching time point can be obtained based on prediction information and movement trajectory information.

[0300] The duration can be indicated by DCI.

[0301] In an example, the first activation condition is that the current service awareness information changes: one, the downlink XR awareness information such as downlink service arrival prediction information or service cycle information obtained from the core network side triggers the MaxMIMOLayer configuration matched with the XR awareness information. Two, the uplink XR awareness information such as uplink service arrival prediction information or service cycle information obtained from the first communication node side triggers the MaxMIMOLayer configuration matched with the XR awareness information.

[0302] The XR awareness information (downlink and uplink) includes: synchronization information; prediction information; service periodicity information; service jitter information; QoS parameters of a packet data unit set (PDU set); PDU set sequence numbers; PDU set packet sizes; sequence numbers of PDUs in a PDU set; end PDU indication of a PDU set; importance information of a PDU set.

[0303] In an example, the first activation condition is that the first communication node reports signaling carrying service awareness information. Specifically, the first communication node reports information signaling includes: UE assistance information (UAI) of the first communication node; MAC CE signaling; and uplink control information (UCI).

[0304] Specifically, the first communication node reports information includes: the first communication node reports first communication node expected Codepoint information to the base station through UCI / MAC CE. The base station can perform MaxMIMO Layer configuration switching according to the first communication node expected Codepoint information.

[0305] In an example, the first activation condition is that the transmission behavior of the first communication node changes:

[0306] Firstly, the transmission behavior switching includes Beam / BWP switching; the BWP switching mode includes:

[0307] Switching is performed through a DCI format 1 series (DL), and BWP switching is triggered when a BWP-ID is indicated in the DCI format 1. After BWP switching, the corresponding RRC signaling or RRC signaling resource set is switched;

[0308] BWP switching is performed through RRC reconfiguration / bwp-InactivityTimer, and the corresponding RRC signaling or RRC signaling resource set is switched after switching;

[0309] BWP switching is performed by initiating a random access procedure in a configured UL BWP, and the corresponding RRC signaling or RRC signaling resource set is switched after switching.

[0310] The second communication node configures two sets of RRC parameters (or two sets of RRC parameter sets), and there are the following switching modes:

[0311] BWP switching mode 1: define a timer, the timer starts counting from the BWP is activated. When the first communication node is in the current BWP, if the time of the first communication node in the current BWP does not reach the time defined by the timer, one set of RRC parameters is used. When the time of the first communication node in the current BWP reaches the time defined by the timer, another set of RRC parameters is used.

[0312] BWP switching mode 2: define a time window, when in the time window of the current BWP, use one set of RRC parameters. When the first communication node is not in the time window of the current BWP, use another set of RRC parameters.

[0313] BWP switching mode 3: define an abnormal situation trigger, when in normal situation, use one set of RRC parameters. When in abnormal situation, use another set of RRC parameters.

[0314] Among them, the abnormal situation includes the following: the data packet loss meets / does not meet the pre-defined threshold value; the CSI measurement (interference measurement) meets / does not meet the pre-defined threshold value.

[0315] Secondly, the transmission behavior switching includes cell reselection / cell switching.

[0316] When the second communication node configures two sets of RRC parameters (or two sets of RRC parameter sets), there are the following switching modes:

[0317] Cell reselection switching mode 1: configure different MaxMIMOLayer configurations for two different cells. When the reselection is not completed, that is, the service cell of the first communication node has not been changed, the MaxMIMOLayer configuration of the current service cell is used. When the reselection is completed, that is, the service cell of the first communication node has changed, the MaxMIMOLayer configuration of the target service cell is used.

[0318] Cell reselection switching mode 2: two cells respectively exist two different MaxMIMOLayer configurations (or parameter set configurations). When the terminal device meets the cell switching condition, the first communication node uses the first MaxMIMOLayer configuration (or parameter set configuration) in the current service cell. When the terminal device does not meet the cell switching condition, the first communication node uses the second MaxMIMOLayer configuration in the current service cell.

[0319] Among them, the switching condition includes:

[0320] The first communication node measures the RSRQ, RSRP or SINR of the neighbor cell to be higher than the pre-defined threshold.

[0321] The reselection incomplete cases include:

[0322] The first communication node measures the RSRQ, RSRP or SINR of the neighbor cell to be higher than a predefined threshold, but the PLMN information in the first communication node has not changed, i.e., the first communication node is currently in a selected target handover cell, or the first communication node is in a reselection request phase.

[0323] Cell reselection handover mode 3: two cells respectively have two different MaxMIMO Layer configurations (or parameter set configurations). When the terminal device switches to the target service cell, when preset condition 1 is met, the first communication node uses the first MaxMIMO Layer configuration. When preset condition 2 is met, the first communication node uses the second MaxMIMO Layer configuration.

[0324] The preset condition 1 includes:

[0325] The first communication node measures the RSRQ, RSRP or SINR of the current cell to be higher than a predefined threshold.

[0326] The preset condition 2 is a mutually exclusive event of the preset condition 1, i.e.:

[0327] The first communication node measures the RSRQ, RSRP or SINR of the current cell to be not lower than a predefined threshold.

[0328] Thirdly, the transmission behavior switching includes beam link failure / recovery.

[0329] Beam failure handover mode 1: two different MaxMIMO Layer configurations (or parameter set configurations) are respectively configured in one beam. When the Beam failure condition occurs, the first MaxMIMO Layer configuration (or parameter set configuration) is used. When the Beam failure condition does not occur, the second MaxMIMO Layer configuration (or parameter set configuration) is used.

[0330] The Beam failure condition includes: (downlink beam failure condition)

[0331] The first communication node measures that the CSI-RS is lower than a predefined threshold within a predefined time interval.

[0332] The base station does not receive the feedback from the first communication node within a predefined time interval, such as not receiving the ACK / NACK feedback of the predefined downlink transmission.

[0333] The base station does not receive the predefined uplink transmission.

[0334] The first communication node reports the beam failure information.

[0335] Beam recovery switching mode 1: one beam configures two different MaxMIMO Layer configurations (or numerology configurations).
