Obviously, the described embodiments are only some of the embodiments of the present disclosure, and not all the embodiments.

[0037] Before describing the technical solutions provided by the embodiments of the present disclosure, first introduce the technical terms related to the embodiments of the present disclosure.

[0038] 1、Dual Connectivity (DC).

[0039] Dual connectivity has become one of the widely used functions to improve data rates in NR systems. In the multi-radio dual connectivity (MR-DC) scenario, a UE is connected with two different nodes, one node acts as a master node (MN) and the other node acts as a secondary node (SN). One node can be a new radio (NR) node and the other node can be a NR or long term evolution (LTE) node. The MN and SN are connected through a network interface and at least the MN is connected to the core network. In addition, the UE can be connected with a master cell group (MCG) associated with the MN and a secondary cell group (SCG) associated with the SN simultaneously. There are three types of bearers in the MR-DC system, including MCG bearers, SCG bearers and split bearers.

[0040] 2. Carrier aggregation (CA).

[0041] After CA is configured, the UE establishes only one RRC connection with the network. At the time of RRC connection establishment / re-establishment / handover, one serving cell provides non-access stratum (NAS) mobility information and at the time of RRC connection re-establishment / handover, one serving cell provides a security input, which is referred to as a primary cell (PCell). Depending on the capabilities of the UE, a secondary cell (SCell) can be configured together with the PCell to form a set of serving cells. Therefore, the set of serving cells configured for a UE always consists of one PCell and one or more SCells.

[0042] Reconfiguration, addition and removal of SCells can be performed by RRC. During handover within a new radio (NR) system and during the resumption of connection from RRC inactive state (RRC_INACTIVE), the network can also add, remove, retain or reconfigure SCells for use with the target PCell. When a new SCell is added, dedicated RRC signaling is used to send all the system information required for the SCell, i.e. in connected mode, the UE does not need to acquire broadcast system information directly from the SCell.

[0043] The NW can configure up to 16 DL carriers and 16 UL carriers for CA for a UE.

[0044] 3. Bandwidth part (BWP).

[0045] To enable bandwidth adaptation techniques on PCell, a next generation nodeB (gNB) configures a UE with UL and DL BWPs. To enable bandwidth adaptation techniques on SCell in the case of CA, a gNB configures a UE with at least a DL BWP (i.e. there can be no BWP in UL). For PCell, the BWP used for initial access is configured through system information. For SCell, the BWP used after initial activation is configured through dedicated RRC signaling.

[0046] In paired spectrum, DL and UL can switch BWP independently. In unpaired spectrum, DL and UL switch BWP simultaneously. Switching between configured BWPs can be done through RRC signaling, downlink control information (DCI), inactivity timer, or at the start of random access. When an inactivity timer is configured for a serving cell, the active BWP switches to the default BWP configured by the network when the inactivity timer associated with the cell expires. There can be at most one active BWP per cell, except for the case when a supplementary uplink (SUL) is configured for the cell, in which case there can be at most one active BWP per UL carrier.

[0047] 4、multi-transmit / receive point (mTRP).

[0048] In multi-TRP operation, a serving cell can schedule a UE from two TRPs, providing better coverage, reliability, and / or data rates for physical downlink shared channel (PDSCH), physical downlink control channel (PDCCH), physical uplink shared channel (PUSCH), and physical uplink control channel (PUCCH).

[0049] There are two different modes of operation to schedule multi-TRP PDSCH transmissions: single-DCI mode and multi-DCI mode. For both modes, the control of uplink and downlink operation can be done by the physical layer and the medium access control (MAC) layer within the configuration provided by the RRC layer. In single-DCI mode, the UE is scheduled by the same DCI of two TRPs; in multi-DCI mode, the UE is scheduled by independent DCI from each TRP.

[0050] There are two different modes of operation for multi-TRP PDCCH: PDCCH repetition and single frequency network (SFN) based PDCCH transmission. In both modes, the UE can receive two PDCCH transmissions, one from each TRP, carrying the same DCI. In PDCCH repetition mode, the UE can receive two PDCCH transmissions carrying the same DCI from two linked search spaces, each search space associated with a different control resource set (CORESET). In SFN based PDCCH transmission mode, the UE can receive two PDCCH transmissions carrying the same DCI from a single search space / CORESET using different transmission configuration index (TCI) states.

[0051] For multi-TRP PUSCH repetition, the UE makes PUSCH transmissions of the same content to two TRPs with corresponding beam directions associated with different spatial relations according to the indication in a single DCI or through semi-statically configured grant provided by RRC. For multi-TRP PUCCH repetition, the UE makes PUCCH transmissions of the same content to two TRPs with corresponding beam directions associated with different spatial relations.

[0052] For inter-cell multi-TRP operation, for multi-DCI PDSCH transmission, one or more TCI states can be associated with synchronization signal / PBCH block (SSB) with a PCI different from the serving cell PCI. At most one TCI state per activation can be associated with a PCI different from the serving cell PCI.

[0053] 5. Mobility enhancements techniques.

[0054] 5.1 Conditional handover (CHO).

[0055] In order to improve the handover reliability (i.e., handover robustness), 5G introduces conditional handover. CHO is defined as a handover performed by the UE when the execution condition is met. The user equipment starts to evaluate the execution condition after receiving the CHO configuration, and stops evaluating the execution condition after the handover is triggered. The CHO configuration includes the candidate cell configuration generated by the candidate target node and the execution condition of the corresponding candidate cell.

[0056] 5.2 Dual active protocol stack handover (DAPS HO).

[0057] In order to reduce the handover interruption time, 5G introduces the DAPS handover procedure. In the DAPS-based handover procedure, the UE maintains the connection with the source cell and the target cell at the same time until the source cell is released after successfully random accessing the target cell.

[0058] 5.3 Layer 1 / layer 2 triggered mobility (L1 / L2 triggered mobility, LTM).

[0059] In order to reduce the handover interruption delay and reduce the handover signaling overhead, 5G introduces LTM. LTM is a process in which the base station triggers cell handover through a cell handover command based on media access control control element (MAC CE) signaling. The cell handover command indicates the LTM candidate cell configuration preconfigured by the base station through RRC signaling, and the UE switches to the corresponding target cell according to the handover command.

[0060] The overall LTM procedure includes four parts: LTM preparation, advance synchronization, LTM cell handover execution, and LTM cell handover completion. Continuous LTM can reuse the preconfigured LTM candidate cell configuration, complete the cell handover by repeating the steps of advance synchronization, LTM cell handover execution, and LTM cell handover completion, and does not need to release other LTM candidate cell configurations after each LTM cell handover completion.

[0061] The above is an introduction to the technical terms related to the embodiments of the present disclosure, which will not be repeated hereinafter.

[0062] When the NW needs to update / switch the radio resource, for example, the configuration of the PCell or the SCell needs to be updated / switched, or the DL / UL configuration in one cell needs to be updated / switched, reconfiguration through RRC signaling (such as through a switching process) is needed, which will cause large signaling overhead and long switching / update delay, affecting the communication performance.

[0063] To solve the above technical problems, for future wireless communication systems (such as 6G), the concept of cell may continue to be used in RRC idle state (RRC_IDLE) or RRC inactive state (RRC_INACTIVE), for example, for mobility management or resource management. However, for RRC connected state (RRC_CONNECTED), the concept of cell in the existing communication architecture may be weakened / removed, and carrier or bandwidth part (BWP) may be used instead of cell, for example, carrier-level or BWP-level resource configuration may be used in RRC configuration instead of cell-level resource configuration. A unified multi-carrier signaling architecture can be used to cover various carrier technologies, such as carrier aggregation (CA), supplementary uplink (SUL), and the like. In addition, flexible association pairing between uplink (UL) carriers and downlink (DL) carriers can also be supported. This flexible carrier / BWP aggregation method can reduce signaling overhead, reduce carrier / BWP activation / switching delay, and / or improve spectrum utilization.

[0064] The scheme of the embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0065] The technical scheme provided by the embodiments of the present disclosure can be applied to various mobile communication networks, for example, NR mobile communication networks using 5G, future mobile communication networks (such as 6G wireless communication systems), or various communication fusion systems, etc., and the embodiments of the present disclosure are not limited thereto.

[0066] FIG. 1 shows a structure of a communication system according to an embodiment of the present disclosure. As shown in FIG. 1, the communication system includes, but is not limited to, a first node 110, a second node 120, and a third node 130. The first node 110, the second node 120, and the third node 130 can transmit, receive, and interact with each other wirelessly.

[0067] In some embodiments, the first node 110 is connected to the second node 120 and the third node 130; wherein the first node 110 is a terminal, the second node 120 is an MN, and the third node 130 is an SN; or the first node 110 is a terminal, the second node 120 is an SN, and the third node 130 is an MN.

[0071] In some embodiments, the second node 120 and the third node 130 can belong to nodes of different RATs, for example, one of the second node 120 and the third node 130 is a 6G node, and the other is an NR node or an LTE node.

As wireless communication technology continues to evolve, future base stations can also be referred to by other names.

[0077] It should be understood that FIG. 1 is an exemplary structural diagram, and the number of devices included in the communication system shown in FIG. 1 is not limited, for example, the number of first nodes and the number of second nodes is not limited. In addition, the communication system shown in FIG. 1 can include other devices in addition to the devices shown in FIG. 1, which is not limited.

[0078] It can be understood that the application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art can know that, as the network architecture evolves and new business scenarios appear, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0079] The wireless network communication method provided by the embodiments of the present disclosure is introduced as follows.

[0080] As shown in FIG. 2, the present disclosure provides a wireless network communication method, which is applied to a first node, and the first node can be the first node 110 shown in FIG. 1. The method includes S201-S202.

[0081] S201, receiving first signaling.

[0082] In some embodiments, in order to facilitate the first node to activate or switch the wireless resource group in a case where the activation or switching condition of the wireless resource group is met, without reconfiguring through RRC signaling, the second node sends the first signaling to the first node, and correspondingly, the first node receives the first signaling from the second node. The second node is a network side device, for example, the second node can be the second node 120 shown in FIG. 1.

[0083] The first signaling is used to configure at least one wireless resource group.

[0084] In some embodiments, the first signaling comprises an RRC message or system information (SI). The configuration of the wireless resource group can be a candidate configuration of the wireless resource group, and each configuration of the wireless resource group is associated with one configuration identity, for example, a configuration index.

[0085] In some embodiments, the wireless resource group comprises at least one of a cell resource group, a carrier resource group, or a bandwidth part resource group, that is, the wireless resource can be at least one of a cell, a carrier, or a bandwidth part.

[0086] In some embodiments, the wireless resource group comprises at least one of a primary wireless resource group, a secondary wireless resource group, an uplink wireless resource group, or a downlink wireless resource group. Taking the wireless resource group as a cell resource group as an example, the wireless resource group comprises at least one of a primary cell resource group, a secondary cell resource group, an uplink cell resource group, or a downlink cell resource group. Taking the wireless resource as a carrier resource group as an example, the wireless resource group comprises at least one of a primary carrier resource group, a secondary carrier resource group, an uplink carrier resource group, or a downlink carrier resource group. Taking the wireless resource as a bandwidth part resource group as an example, the wireless resource group comprises at least one of a primary bandwidth part resource group, a secondary bandwidth part resource group, an uplink bandwidth part resource group, or a downlink bandwidth part resource group.

[0087] It should be noted that according to the 5G protocol, a special cell (SpCell) contains a PCell and a primary secondary cell (PSCell). The PCell is the primary cell in the master cell group (MCG), and the UE can perform an initial connection establishment process or initiate a connection re-establishment process in this cell.

[0088] PSCell definition: the primary cell in the secondary cell group (SCG), and for dual connectivity (DC) operation, the UE performs a random access on this cell when performing a synchronization reconfiguration process.

[0089] SCell definition: for a UE configured with CA, an SCell can provide additional wireless resources based on the SpCell.

[0090] Compared with the SCell, the SpCell additionally has the functions of providing NAS mobile information, RRC re-establishment, security input, cell radio network temporary identifier (C-RNTI) allocation, etc.

[0091] As can be known from the above description of the cell, with the development of communication technology, a carrier or a bandwidth part can be used to replace the cell in the future. Therefore, based on the cell including a primary cell, a secondary cell, an uplink cell, or a downlink cell, the embodiments of the present disclosure propose that the carrier includes a primary carrier, a secondary carrier, an uplink carrier, or a downlink carrier, and the bandwidth part includes a primary bandwidth part, a secondary bandwidth part, an uplink bandwidth part, or a downlink bandwidth part. For ease of description, the following embodiments take the wireless resource as an example to describe the carrier, and it should be noted that the carrier described below can also be replaced by the cell or the bandwidth part or other similar functional wireless resources.

[0092] Based on the carrier including a primary carrier, a secondary carrier, an uplink carrier, or a downlink carrier, the primary carrier is the main carrier in the carrier group, and the UE can perform initial connection establishment or initiate a re-establishment process on this carrier. The secondary carrier is another carrier that can be used / aggregated with the primary carrier in the carrier group, and can provide additional wireless resources based on the primary carrier. Compared with the secondary carrier, the primary carrier additionally has the functions of providing NAS mobility information, RRC re-establishment, security input, and / or wireless network temporary identifier (such as CRNTI) allocation. The primary carrier can also be referred to as a "special carrier" or an "anchor carrier", and the embodiments of the present disclosure do not limit this.

[0093] For dual / multi-connection operation, the primary carrier can contain / indicate the primary carrier in the master carrier group and / or the primary carrier in the secondary carrier group. The primary carrier in the secondary carrier group can also be referred to as the "primary secondary carrier", that is, the UE performs random access on this carrier when performing a synchronization reconfiguration process.

[0094] The master carrier group is a group of carriers associated with the master node (MN), which includes the primary carrier and / or the secondary carrier. The secondary carrier group is a group of carriers associated with the secondary node (SN), which includes the primary secondary carrier and / or the secondary carrier.

[0095] In the following description, the second node can be a master node or a secondary node, and accordingly, the third node can be a secondary node or a master node.

[0096] From the perspective of signaling configuration, the second node can not fix the configuration of PCell and SCell (or similar function carrier, BWP) or the configuration of UL and DL when providing the wireless resource configuration in the wireless resource group through the first signaling. The second node can pre-configure the configuration of multiple wireless resource groups for the first node through the first signaling. The first node can autonomously select one or more wireless resource groups in the multiple wireless resource groups to apply / activate based on the indication of the second node or based on the execution condition pre-configured by the second node. The indication of the second node can be sent through signaling such as RRC signaling, MAC CE, or DCI. The execution condition pre-configured by the second node can include the measurement configuration associated / corresponding to the wireless resource group, the measurement event, the signal quality threshold, the data flow threshold, etc. The first node can automatically activate / apply or deactivate / disable the corresponding wireless resource group according to whether the execution condition associated / corresponding to the wireless resource group is met.

[0097] In some embodiments, the first signaling includes the configuration of at least one wireless resource group, and the configuration of the wireless resource group includes the configuration of each wireless resource in the wireless resource group.

[0098] Taking the wireless resource as an example, the second node configures one or more carrier groups, and each carrier group includes the configuration of multiple carriers. The configuration of each carrier can include the configuration similar to the configuration of a serving cell (ServingCellConfig), such as the configuration including the following: frequency domain bandwidth range, reference signal (RS), common channel, dedicated channel, BWP, mTRP, and / or measurement, etc.

[0099] In some embodiments, the at least one wireless resource group includes an uplink wireless resource group and a downlink wireless resource group; or the at least one wireless resource group includes a primary wireless resource group and a secondary wireless resource group; or the at least one wireless resource group includes a common wireless resource group.

[0100] As an example, the wireless resources in the common wireless resource group can include at least one of a primary wireless resource, a secondary wireless resource, a wireless resource that can be both a primary wireless resource and a secondary wireless resource, an uplink wireless resource, a downlink wireless resource, and a wireless resource that can be both an uplink wireless resource and a downlink wireless resource. The configuration of the common wireless resource group includes first indication information and / or second indication information of each wireless resource, the first indication information being used to indicate that the configuration of the wireless resource can be activated or applied as a primary wireless resource and / or a secondary wireless resource, and the second indication information being used to indicate that the configuration of the wireless resource can be activated or applied as an uplink wireless resource and / or a downlink wireless resource. For example, for each carrier in the common carrier group, the second indication information corresponding to the carrier is used to indicate whether the carrier can be an uplink carrier, a downlink carrier, or both (e.g., a time division duplex carrier). The first indication information corresponding to the carrier is used to indicate whether the carrier can be a primary carrier, a secondary carrier, or both.

[0101] In some embodiments, the second node can also indicate the association between the uplink wireless resources and the downlink wireless resources in the common wireless resource group through RRC configuration or a dynamic activation / switching command, such as associating the uplink wireless resources and the downlink wireless resources through UL / DL wireless resource indexes / identifiers.

[0102] In some embodiments, the uplink wireless resource group is used to determine the uplink wireless resources to be activated, and the downlink wireless resource group is used to determine the downlink wireless resources to be activated. That is, the uplink wireless resources to be activated are determined from the uplink wireless resource group, and the downlink wireless resources to be activated are determined from the downlink wireless resource group.

[0103] In some embodiments, in the case where the second node indicates the wireless resources to be activated, the second node can also indicate the association between the uplink wireless resources to be activated and the downlink wireless resources to be activated. The association can be represented by associating the UL carrier indexes / identifiers with the DL carrier indexes / identifiers. The association can be as follows:

[0104] One UL is associated with one DL; one UL is associated with multiple DLs; one DL is associated with multiple ULs (e.g., one normal uplink (NUL) and one supplementary uplink (SUL)); there is only one DL, and no associated UL; there is only one UL, and no associated DL.

[0105] For the associated UL wireless resources and DL wireless resources, the first node can receive a downlink signal on the DL wireless resource and transmit an uplink signal on the associated UL wireless resource.

[0106] In some embodiments, the primary radio resource group is used to determine the primary radio resource to be activated, and the secondary radio resource group is used to determine the secondary radio resource to be activated. That is, the primary radio resource to be activated is determined from the primary radio resource group, and the secondary radio resource to be activated is determined from the secondary radio resource group. The activated primary radio resource and the activated secondary primary radio resource can be aggregated into one CA group.

[0107] In some embodiments, one or more BWPs can also be configured under each carrier.

[0108] Taking wireless resources as an example, referring to FIG. 3, a multi-carrier configuration framework provided by an embodiment of the present disclosure is shown. The second node can provide an RRC configuration (for example, through an RRC reconfiguration message or a system message), and the RRC configuration can include at least one of radio bearer configuration, carrier group configuration, and measurement configuration. The carrier group configuration includes configuration of one or more carriers, radio link control (RLC) / medium access control (MAC) configuration, and common carrier configuration. One carrier can be associated with one or more mTRPs.

[0109] Taking a bandwidth part as an example, referring to FIG. 4, a multi-bandwidth part configuration framework provided by an embodiment of the present disclosure is shown. The second node can provide an RRC configuration (for example, through an RRC reconfiguration message or a system message), and the RRC configuration can include at least one of radio bearer configuration, bandwidth part group configuration, and measurement configuration. The bandwidth part group configuration includes configuration of one or more bandwidth parts, RLC / MAC configuration, and common bandwidth part configuration. One bandwidth part can be associated with one or more mTRPs.

[0110] In some embodiments, the configuration of a wireless resource group comprises the configuration of at least one wireless resource subset, and the configuration of a wireless resource subset comprises the configuration of one or more wireless resources in the wireless resource group. That is, the wireless resources in a wireless resource group can be divided into multiple wireless resource subsets (subsets of wireless resources), and each wireless resource subset can contain one or more wireless resources. The second node can dynamically indicate the activation or deactivation of a wireless resource subset (e.g., indicate the identification / index of the wireless resource subset) to activate / apply a set of wireless resources. For example, one or more downlink wireless resources and / or one or more uplink wireless resources can be contained in a wireless resource subset. There can be only one downlink wireless resource in a wireless resource subset carrying downlink reference signal information (e.g., SSB or channel state information-reference signal (CSI-RS) configuration for synchronization and channel state measurement), or a set of common downlink reference signal information can be contained in a wireless resource subset. The reference signal information can be used for synchronization and channel state measurement of all DL wireless resources in the wireless resource subset. For the activated / used set of wireless resource subsets, the second node can dynamically indicate the flexible pairing of UL wireless resources and DL wireless resources through a dynamic activation command (e.g., MAC CE, DCI), or the first node can flexibly select the paired UL wireless resources according to the measurement of the DL wireless resources (e.g., in the initial access stage). The above wireless resource subset can be applied to the functions of multi-band service cell (MBSC) or multi-band aggregation.

[0111] In some embodiments, referring to FIG. 5, another multi-carrier configuration framework provided by the embodiments of the present disclosure is shown. A bandwidth part group can also be contained under a carrier group. For example, each bandwidth part group corresponds to one or more bandwidth parts on one carrier, or each bandwidth part group contains bandwidth parts on different carrier frequency bands (similar to the concept of multi-band serving cell (MBSC)).

[0112] In some embodiments, the multiple wireless resources in the same wireless resource group can be intra-band continuous wireless resources, intra-band non-continuous wireless resources, and / or inter-band non-continuous wireless resources.

[0113] In some embodiments, the multiple wireless resources in the same wireless resource group belong to the same MAC management.

[0114] The above embodiments are used to illustrate the configuration of wireless resources, for example, the resource configuration in single connection. The following describes the configuration of multiple wireless resource groups (for example, the resource configuration for multiple connections) in combination with the above configuration of wireless resources.

[0115] In some embodiments, in multiple connections, the first node can be connected with two or more different nodes. For example, the first node is connected with the second node and the third node. One node acts as a master node (MN), and the other node or nodes act as a secondary node (SN). The above nodes can be nodes belonging to the same RAT (for example, two or more nodes are 6G nodes or NR nodes), or nodes belonging to different RATs (for example, one of the above nodes is a 6G node, and the other nodes are NR nodes or LTE nodes). In multiple connections, the MN and the SN can belong to different nodes or belong to the same node.

[0116] In some embodiments, for multiple connection configuration, the network side (for example, the second node and / or the third node) can pre-configure multiple wireless resource groups, for example, corresponding to multiple cell resource groups (cell groups) in NR. The network side (for example, the second node and / or the third node) can dynamically activate one or more wireless resource groups in the multiple wireless resource groups through signaling (for example, RRC signaling, MAC CE signaling, DCI signaling) to support multiple connection (including dual connection or more than two connections) operation, for example, addition, switching, activation, deactivation of secondary wireless resource groups, switching, activation, deactivation of primary wireless resource groups.

[0117] In some embodiments, the first signaling includes the configuration of at least one primary wireless resource group and the configuration of at least one secondary wireless resource group.

[0118] In some embodiments, the at least one primary wireless resource group is used to determine the primary wireless resource group to be activated, and the at least one secondary wireless resource group is used to determine the secondary wireless resource group to be activated. That is, the primary wireless resource group to be activated is determined from the at least one primary wireless resource group configured by the second node, and the secondary wireless resource group to be activated is determined from the at least one secondary wireless resource group configured by the second node.

[0119] It should be noted that the above "primary" and "secondary" are mainly used to distinguish two series of wireless resource group configurations. For example, one series of wireless resource group configurations is associated with the configuration of the master node (for example, generated / provided by the MN), and the other series of wireless resource group configurations is associated with the configuration of the secondary node (for example, generated / provided by the SN).

[0120] In some embodiments, the first signaling comprises a configuration of at least one set of wireless resources, the configuration of the set of wireless resources comprising a configuration of one or more groups of wireless resources in the set of wireless resources. The configuration of the groups of wireless resources in the set of wireless resources comprises a configuration of a primary group of wireless resources and / or a configuration of a secondary group of wireless resources. The configuration of all groups of wireless resources in one set of wireless resources can be activated or applied at the same time, for example, one group of wireless resources in one set of wireless resources as a primary group of wireless resources, and the other groups of wireless resources as secondary groups of wireless resources.

[0121] Taking the group of wireless resources as an example of the carrier group, referring to FIG. 6, a schematic diagram of a multi-carrier group configuration framework provided by an embodiment of the present disclosure is shown. The second node can provide one RRC configuration (for example, through an RRC reconfiguration message or a system message), and the RRC configuration can comprise at least one of a radio bearer configuration, a carrier set configuration, and a measurement configuration. The carrier set configuration comprises a configuration of one or more carrier groups. The configuration of the carrier groups in the carrier set comprises a configuration of a primary carrier group and / or a configuration of a secondary carrier group. One carrier group configuration comprises one or more carrier configurations, RLC / MAC configurations, and general / common carrier configurations. One carrier can be associated with one or more mTRPs.

[0122] In some embodiments, the wireless resource or the group of wireless resources has at least one associated radio bearer configuration.

[0123] The radio bearer configuration (RadioBearerConfig) is used to configure a signaling radio bearer (SRB) and / or a data radio bearer (DRB). The radio bearer configuration can comprise a packet data convergence protocol (PDCP) configuration, a service data adaptation protocol (SDAP) configuration, and / or a security configuration, etc.

[0124] In some embodiments, the second node can configure radio bearers through radioBearerConfig and radioBearerConfig2, for example, one for configuring an MN terminated bearer, and the other for configuring an SN terminated bearer.

[0125] The second node can pre-configure multiple sets of radio bearer configurations. Each set of radio bearer configurations is associated with / contains an identifier of one radio bearer configuration.

[0126] In some embodiments, the second node can provide the association between the radio bearer configuration and the radio resource group configuration through RRC configuration. For example, one radio resource group is associated with a set of radio bearer configurations.

[0127] In some implementations, the radio resource groups can be divided into a plurality of radio resource group sets, and one radio resource group set contains one or more radio resource groups. When the radio resource group to be activated or switched by the second node belongs to the same radio resource group set as the currently activated or applied radio resource group of the first node, the radio bearer configuration of the first node remains unchanged. Accordingly, the first node can not need to perform L2 reset related operations in the process of performing radio resource group activation or switching. For example, at least one of the following operations is not required: Packet Data Convergence Protocol (PDCP) re-establishment, PDCP data recovery, Radio Link Control (RLC) re-establishment, and Media Access Control (MAC) reset. When the radio resource group to be activated or switched by the second node does not belong to the same radio resource group set as the currently activated or applied radio resource group (i.e., activation or switching across radio resource group sets), the first node needs to activate or apply the radio bearer configuration associated with the target radio resource group. Accordingly, the UE needs to perform L2 reset related operations in the process of performing radio resource activation or switching, for example, at least one of the following operations is required: PDCP re-establishment, PDCP data recovery, RLC re-establishment, and MAC reset.

[0128] In some embodiments, the first node can determine whether the target radio resource group and the currently activated or applied radio resource group belong to the same radio resource group set according to the relevant configuration ID of the radio resource group. For example, when the radio bearer related configuration ID (or L2 reset related configuration ID) of the target radio resource group and the radio bearer related configuration ID (or L2 reset related configuration ID) of the currently activated or applied radio resource group are the same, they belong to the same radio resource group set; otherwise, they do not belong to the same radio resource group set.

[0129] In some embodiments, the second node can dynamically indicate or activate the corresponding radio bearer configuration when dynamically activating the radio resource group.

[0130] In some embodiments, the first signaling further includes indication information for indicating the state of at least one radio resource group. For example, the configuration of each radio resource group is associated with a state indication information.

[0131] For example, the state of at least one radio resource group includes at least one of the following: a pre-configuration state, a pre-configuration suspended state, an activated state, and a deactivated state.

[0132] The description of the state of the at least one wireless resource group will be described in the embodiments provided below, and will not be described here.

[0133] S202, based on a preset condition, activating or switching at least one target wireless resource group in the at least one wireless resource group.

[0134] In some embodiments, the at least one target wireless resource group is used for multi-connection.

[0135] Exemplarily, the target wireless resource group includes a primary wireless resource group and / or a secondary wireless resource group. The second node can configure at least one wireless resource group, and dynamically activate or apply one wireless resource group in the at least one wireless resource group as a primary wireless resource group, and one or more wireless resource groups in the at least one wireless resource group as secondary wireless resource groups.

[0136] Exemplarily, the target wireless resource group includes a primary wireless resource group and / or a secondary wireless resource group. The second node can configure at least one primary wireless resource group and / or at least one secondary wireless resource group. When activating or switching the at least one target wireless resource group, the second node selects a primary wireless resource group to be activated from the at least one primary wireless resource group, and / or selects a secondary wireless resource group to be activated from the at least one secondary wireless resource group. The activated primary wireless resource group and the secondary wireless resource group form a multi-connection.

[0137] Exemplarily, the second node can pre-configure a plurality of wireless resource sets, each wireless resource set including one or more wireless resource groups. The second node can dynamically activate one wireless resource set in the plurality of wireless resource sets, i.e., all wireless resource groups contained in the set are activated or applied. The second node can also indicate which wireless resource group in the wireless resource set is the primary wireless resource group and which wireless resource group is the secondary wireless resource group through RRC configuration or dynamic activation / switching command.

[0138] In some embodiments, the second node can also indicate which wireless resource in the primary wireless resource group and / or the secondary wireless resource group is the primary wireless resource and which wireless resource is the secondary wireless resource through RRC configuration or dynamic activation / switching command.

[0139] In some embodiments, the second node can also indicate the association relationship between the uplink wireless resources and the downlink wireless resources in the wireless resource group through RRC configuration or dynamic activation / switching command, such as associating the uplink wireless resources and the downlink wireless resources through UL / DL wireless resource configuration index / identification.

[0140] As an example, the preset condition includes at least one of the following:

[0141] Condition 1, receiving the second signaling, wherein the second signaling is used to indicate to activate or switch the at least one target radio resource group.

[0142] In some embodiments, the receiving the second signaling can be receiving the second signaling from the second node. That is, the second node sends the second signaling to the first node in case the second node needs the first node to activate or switch the radio resource group. Accordingly, the first node receives the second signaling from the second node.

[0143] In some embodiments, the second signaling comprises L1 signaling (e.g., DCI), L2 signaling (e.g., MAC CE), or L3 signaling (e.g., RRC message).

[0144] In some embodiments, the second signaling comprises at least one of: an identification of a configuration of the target radio resource group; an identification of a configuration of a radio resource in the target radio resource group; a bitmap of indices of a configuration of a radio resource in the target radio resource group; indication information for indicating whether a primary radio resource group and a secondary radio resource group currently serving are role-exchanged; an identification of a radio bearer configuration associated with the target radio resource group; indication information for indicating that the radio bearer configuration associated with the target radio resource group is a bearer configuration terminated at the second node, for example, in a case that the second node is a MN, the indication information is indication information for indicating that the radio bearer configuration associated with the target radio resource group is a MN terminated bearer configuration; in a case that the second node is a SN, the indication information is indication information for indicating that the radio bearer configuration associated with the target radio resource group is a SN terminated bearer configuration; indication information for indicating that the radio bearer configuration associated with the target radio resource group is a bearer configuration terminated at a third node, for example, in a case that the third node is a MN, the indication information is indication information for indicating that the radio bearer configuration associated with the target radio resource group is a MN terminated bearer configuration; in a case that the third node is a SN, the indication information is indication information for indicating that the radio bearer configuration associated with the target radio resource group is a SN terminated bearer configuration; a radio network temporary identifier (e.g., C-RNTI) of the target radio resource group, for example, a radio network temporary identifier for the primary radio resource group, and / or a radio network temporary identifier for the secondary radio resource group; an identification of a transmission reception point (TRP) associated with the target radio resource group; maximum time advance information of the target radio resource group, for example, maximum time advance information for the primary radio resource group, and / or maximum time advance information for the secondary radio resource group; indication information for indicating whether the target radio resource group is a primary radio resource group or a secondary radio resource group; indication information for indicating whether a random access procedure is performed to the target radio resource group; information required for performing a random access to the target radio resource group.

[0145] Exemplarily, the identification (e.g., index or ID) of the configuration of the target radio resource group can comprise at least one of: an identification of a configuration of a common radio resource group, an identification of a configuration of a primary radio resource group, an identification of a configuration of a secondary radio resource group. It can be understood that the identification of the configuration of the target radio resource group comprised in the second signaling is for indicating that the target radio resource group corresponding to the identification is activated or applied, or for indicating that the target radio resource group corresponding to the identification is activated or applied as a primary radio resource group or a secondary radio resource group.

[0146] Exemplarily, the second signaling comprises an identification of a configuration of a wireless resource in the target wireless resource group, which can be used to indicate that the wireless resource is activated or applied, or used to indicate that the wireless resource is activated or applied as a primary wireless resource or a secondary wireless resource.

[0147] Exemplarily, the second signaling comprises a bitmap of indices of configurations of wireless resources in the target wireless resource group. Each bit in the bitmap identifies an index representing a configuration of a wireless resource or a wireless resource group with the same index value. Each bit can be set to 0 or 1, where 0 represents that the wireless resource or the wireless resource group is deactivated or the configuration is not applied, and 1 represents that the wireless resource or the wireless resource group is activated or applied.

[0148] Exemplarily, the second signaling comprises indication information for indicating whether the primary wireless resource group and the secondary wireless resource group of the current service are role-exchanged. The indication information can be an indicator or a flag. For example, the primary wireless resource group of the current service is activated or applied as a secondary wireless resource group, or the secondary wireless resource group of the current service is activated or applied as a primary wireless resource group.

[0149] Exemplarily, the second signaling comprises information required by the first node to perform random access to the target wireless resource group in the activation or switching process. For example, the information required to perform random access comprises at least one of the following: an UL wireless resource on which the first node performs a RACH process (e.g., an ID of the UL wireless resource), a random access preamble index, an SSB reference signal index (e.g., for determining a RACH occasion for PRACH transmission), a PRACH mask index (for indicating a RACH occasion associated with the SSB).

[0150] In some embodiments, the second signaling can further comprise at least one of the following:

[0151] a wireless network temporary identifier (e.g., C-RNTI) value of the target wireless resource group, wherein the first node can apply the wireless network temporary identifier value of the target wireless resource group as a current wireless network temporary identifier value; a maximum timing advance (TA) value or a compensated TA value of the target wireless resource group; an identification of an activated uplink BWP and / or an identification of an activated downlink BWP under a target carrier in the case that the target wireless resource group is a carrier resource group; an identification of an activated TCI state under the target wireless resource, such as an identification of an UL TCI state, an identification of a DL TCI state, an identification of a joint TCI state, etc.; indication information for indicating an identification of a wireless resource associated with an opposite transmission direction of an activated wireless resource in the target wireless resource group, for example, indication information for indicating an identification of an UL or DL wireless resource associated with a DL or UL wireless resource activated or applied in the target wireless resource group.

[0152] Condition 2: at least one target radio resource group satisfies a corresponding execution condition for activation or switching.

[0153] In some embodiments, the execution condition for activation or switching of the at least one target radio resource group is pre-configured by the second node, indicated by the second node, pre-negotiated by the first node and the second node, or pre-negotiated by the second node and a third node. The execution condition comprises at least one of: a measurement configuration, a measurement event, a data traffic threshold. The first node can automatically activate or switch the configuration of the corresponding target radio resource group according to whether the corresponding execution condition is satisfied, for example, a mechanism similar to conditional handover (CHO).

[0154] It should be understood that condition 1 above is that the second node instructs the first node to activate or switch the radio resource, and condition 2 is that the first node autonomously activates or switches the radio resource.

[0155] In some embodiments, for each target radio resource group of the at least one target radio resource group, the target radio resource group satisfies a corresponding execution condition for activation or switching comprises at least one of:

[0156] For the execution condition configured for the primary radio resource in the target radio resource group, for example, it can be a measurement configuration corresponding to the primary radio resource;

[0157] For the execution condition configured for one or more radio resources in the target radio resource group; for example, the execution condition comprises a plurality of trigger conditions, each trigger condition is associated with a measurement configuration of a different radio resource, or each trigger condition is associated with different measurement configurations of the same radio resource.

[0158] In some embodiments, the target radio resource group comprises a plurality of radio resources, the execution condition comprises a plurality of trigger conditions corresponding to one or more radio resources, for example, each radio resource of the plurality of radio resources corresponds to a trigger condition; the target radio resource group satisfies a corresponding execution condition for activation or switching comprises at least one of:

[0159] In the case that one or more trigger conditions of the plurality of trigger conditions are satisfied, activate or switch the radio resource corresponding to the satisfied trigger condition in the target radio resource group;

[0160] In the case that all of the plurality of trigger conditions are satisfied, activate or switch all radio resources in the target radio resource group;

[0161] In the case that only one trigger condition of the plurality of trigger conditions is satisfied, activate the radio resource corresponding to the satisfied trigger condition in the target radio resource group, wherein the radio resource is the primary radio resource;

[0162] In a case that only one of the trigger conditions is satisfied, all the radio resources in the target radio resource group are activated, wherein the radio resource corresponding to the satisfied trigger condition is taken as the primary radio resource.

[0163] For example, in a case that the target radio resource group includes a primary radio resource (e.g., the primary radio resource is indicated in the RRC configuration sent by the second node), and the activation or switching condition includes a trigger condition corresponding to the primary radio resource, in a case that the trigger condition corresponding to the primary radio resource is satisfied, the first node can determine that the target radio resource group satisfies the execution condition of switching or activation, and then automatically activate or switch the target radio resource group. In addition, the first node can automatically activate or apply one or more radio resources in the target radio resource group for which the corresponding trigger condition is satisfied (e.g., one of the one or more radio resources is taken as the primary radio resource, and the other radio resources are taken as secondary radio resources).

[0164] The activation or switching of the radio resource group or the radio resource by the first node described above can include that the first node selects the radio resource group or the radio resource as the target radio resource group or the target radio resource, applies the configuration of the radio resource group or the radio resource, and / or performs the operation required for the activation or switching of the radio resource group or the radio resource (e.g., performs the random access operation on the radio resource group or the radio resource).

[0165] In some embodiments, S202 described above can include the following implementation manners:

[0166] In a case that all the trigger conditions are satisfied, the first node can activate or switch the radio resources corresponding to the trigger conditions. The activated or switched radio resources include the primary radio resource and the secondary radio resource. For example, the first node can select one radio resource from the multiple radio resources to activate or apply as the primary radio resource, e.g., the first node can determine the primary radio resource according to the configuration information or indication information in the RRC configuration of the radio resource indicating whether the radio resource can be taken as the primary radio resource; and activate or apply the radio resources other than the primary radio resource as the secondary radio resources.

[0167] In a case that only one of the trigger conditions is satisfied, the radio resource corresponding to the satisfied trigger condition is activated or applied, and the radio resource is taken as the primary radio resource.

[0168] In some embodiments, S202 described above can be implemented as follows: in a case that the first node receives the second signaling sent by the second node, or the first node determines that at least one target radio resource group satisfies the execution condition of activation or switching, the first node triggers or performs the activation or switching of the at least one target radio resource. For example, the first node can perform at least one of the following operations:

[0169] activating or applying the configuration of the radio resource group indicated by the second node or the configuration of the radio resource group selected by the first node;

[0170] applying the TA value of the target radio resource group indicated by the second node or selected by the first node or applying a compensation TA value based on the current TA value, for example, if the related TA information of the target radio resource group to be activated or applied is indicated in the second signaling or provided by the second node or the valid TA information of the target radio resource group to be activated or applied is acquired by the first node;

[0171] applying the radio network temporary identifier (e.g., C-RNTI) value of the target radio resource group indicated by the second node or selected by the first node (e.g., if the radio network temporary identifier of the target radio resource group to be activated or applied is indicated in the second signaling or provided by the second node);

[0172] starting a timer, wherein the timer is used to monitor the target radio resource group activation or handover process;

[0173] deactivating or deactivating the currently served radio resource group if the currently served radio resource group is not within the range of the activated or applied target radio resource group indicated by the second node or selected by the first node;

[0174] disconnecting the connection with the currently served radio resource group, synchronizing and / or accessing the target radio resource group indicated by the second node or selected by the first node;

[0175] initiating a random access procedure to access the target radio resource group indicated by the second node or selected by the first node, for example, according to the indication of the second node or the second signaling, the target radio resource group activation or handover process needs to perform a random access procedure; or the first node and the target radio resource have not performed / completed the uplink synchronization process; or the first node has not acquired the TA of the target radio resource in advance;

[0176] If the first node does not need to initiate a random access procedure, the first node can receive an uplink grant (UL grant) by listening to the PDCCH scheduling of the target radio resource group indicated by the second node or selected by the first node to send uplink signals through the uplink grant; or send uplink signals to the target radio resource group indicated by the second node or selected by the first node according to the preconfigured configuration grant of the second node; for example, the first node can select the associated configuration grant slot according to the TCI state information of the main radio resource in the target radio resource group indicated in the second signaling to send uplink signals;

[0177] The first node sends an uplink signal (such as an RRC message, a MAC CE, uplink control information (UCI), a channel state information (CSI) / channel quality indication (CQI) report, etc.) to the target radio resource group indicated by the second node or selected by the first node to notify the execution or completion of the process of activating / switching to the target radio resource group. The uplink signal can include information of the activated / applied target radio resource group, such as an identifier / index of the target radio resource group, an identifier / index of the primary radio resource in the target radio resource group, an identifier / index of the radio bearer configuration associated with the target radio resource group, and / or an identifier / index of the TRP associated with the target radio resource group, etc.

[0178] Based on the embodiment shown in FIG. 2, the second node pre-configures at least one radio resource group through the first signaling, so that the first node can activate or switch at least one target radio resource group in the at least one radio resource group based on a preset condition. In this way, by pre-configuring the at least one radio resource group, at least one target radio resource group can be activated or switched directly to complete the activation or switching of the radio resource group when the preset condition is met, i.e., when the radio resource group needs to be activated or switched, without the need for reconfiguration through RRC signaling, thereby reducing the signaling overhead of activating or switching the radio resource, and reducing the latency of radio resource switching / activation, which helps to improve the spectrum utilization.

[0179] In some embodiments, the present disclosure also provides a wireless network communication method applied to a second node. The second node can be the second node 120 in the communication system shown in FIG. 1. As shown in FIG. 7, the method can include S301-S302.

[0180] S301, the second node sends first signaling to the first node.

[0181] In some embodiments, in order to reduce the signaling overhead of the first node switching the radio resource, the second node sends the first signaling to the first node. The first signaling is used to configure at least one radio resource group.

[0182] For the description of the first signaling and the configuration of the at least one radio resource group, reference can be made to the corresponding description in the embodiment shown in FIG. 2 above, which will not be repeated here.

[0188] In some embodiments, the wireless resource in the common wireless resource group can comprise at least one of a primary wireless resource, a secondary wireless resource, a wireless resource that can be used as a primary wireless resource or a secondary wireless resource, an uplink wireless resource, a downlink wireless resource, or a wireless resource that can be used as an uplink wireless resource or a downlink wireless resource. The first indication information and / or the second indication information of each wireless resource in the configuration of the common wireless resource group are included, the first indication information is used to indicate that the configuration of the wireless resource can be activated or applied as a primary wireless resource and / or a secondary wireless resource, and the second indication information is used to indicate that the configuration of the wireless resource can be activated or applied as an uplink wireless resource and / or a downlink wireless resource. For example, for each carrier in the common carrier group, the second indication information corresponding to the carrier is used to indicate whether the carrier can be used as an uplink carrier, a downlink carrier, or both (such as a time division duplex carrier). The first indication information corresponding to the carrier is used to indicate whether the carrier can be used as a primary carrier, a secondary carrier, or both.

[0189] In some embodiments, the configuration of the wireless resource group comprises multiple sets of configurations of each wireless resource in the wireless resource group, and the multiple sets of configurations of a wireless resource are configurations of the wireless resource under different purposes.

[0190] In some embodiments, the multiple sets of configurations of a wireless resource comprise a first configuration and a second configuration, the first configuration is used to determine the configuration of the wireless resource when the wireless resource is used as a primary wireless resource, and the second configuration is used to determine the configuration of the wireless resource when the wireless resource is used as a secondary wireless resource; or the multiple sets of configurations of a wireless resource comprise a third configuration, a fourth configuration, and a fifth configuration; wherein the third configuration and the fourth configuration are jointly used to determine the configuration of the wireless resource when the wireless resource is used as a primary wireless resource, and the third configuration and the fifth configuration are jointly used to determine the configuration of the wireless resource when the wireless resource is used as a secondary wireless resource.

[0191] In some embodiments, the configuration of the wireless resource group comprises a common configuration and a dedicated configuration of each wireless resource, the common configuration being a same configuration or a reference configuration common to each wireless resource in the wireless resource group, and the dedicated configuration being a differential configuration or an incremental configuration based on the reference configuration of each wireless resource in the wireless resource group.

[0192] S302, the second node sends second signaling to the first node.

[0193] The second signaling is used to indicate activation or switching of at least one target wireless resource group in the at least one wireless resource group.

[0197] In some embodiments, the second signaling can further comprise at least one of the following:

[0198] a radio network temporary identifier (e.g., C-RNTI) value of the target radio resource group, where the first node can apply the radio network temporary identifier value of the target radio resource group as a current radio network temporary identifier value; a maximum timing advance (TA) value or a compensated TA value of the target radio resource group; in a case that the target radio resource group is a carrier resource group, an identification of an activated uplink BWP and / or an identification of an activated downlink BWP under the target carrier; an identification of an activated TCI state under the target radio resource, such as an identification of an UL TCI state, an identification of a DL TCI state, an identification of a joint TCI state, etc.; and indication information used to indicate an identification of a radio resource associated with a reverse transmission direction of an activated radio resource in the target radio resource group.

[0199] In some embodiments, the second node sends an execution condition of activating or switching the target radio resource group to the first node. For the description of the execution condition, reference can be made to the corresponding description in the embodiment shown in FIG. 2, which will not be repeated here.

[0200] Based on the embodiment shown in FIG. 7, the second node sends the first signaling used to configure at least one radio resource group to the first node in advance, so that the first node can activate or switch the target radio resource group in the at least one radio resource group based on a preset condition, that is, when the radio resource group switching condition is met, the switching of the radio resource group can be directly performed without reconfiguration through the RRC signaling, which reduces the signaling overhead of switching the radio resource group and reduces the latency of the radio resource group switching / activation, and helps to improve the spectrum utilization.

[0201] In some embodiments, from the perspective of the network side, the configuration of the radio resource group can be generated by the MN or the SN (i.e., the second node or the third node described above), for example, the MN generates the configuration of the primary radio resource group, and the SN generates the configuration of the secondary radio resource group.

[0202] In the existing DC, the MN and the SN need to perform inter-station or inter-node coordination to ensure that the configurations on the MCG and SCG sides meet the requirements or limitations of the first node's capability (e.g., a list of allowed frequency band combinations, uplink power coordination, a maximum number of configurable measurement frequency points or a number of measurement IDs, etc.).

[0203] For the multi-connection scheme based on multiple radio resource groups, inter-station or inter-node coordination is also needed to ensure that the radio resource groups activated or applied by the first node at the same time do not exceed the maximum first node capability limitation.

[0204] Exemplarily, the embodiment of the present disclosure needs inter-node coordination between the second node and the third node before sending the second signaling, i.e., before the S302, the method further includes S401-S403 as shown in FIG. 8.

[0205] S401, the second node sends first information to the third node; correspondingly, the third node receives the first information sent by the second node. The first information is used to indicate the information of the wireless resource group selected by the second node to be activated or switched.

[0206] In some embodiments, the first information includes at least one of the following: the information of the wireless resource group selected by the second node to be activated or switched, such as the index or ID of the wireless resource group configuration, or the frequency point or frequency band information of the wireless resource group; the information of the wireless resource to be activated in the wireless resource group selected by the second node to be activated or switched; the number of the wireless resource to be activated in the wireless resource group selected by the second node to be activated or switched; the list of the frequency band combination supported by the first node; the maximum number of the activatable wireless resource in the wireless resource group configured by the third node; the indication information indicating whether the primary wireless resource group and the secondary wireless resource group currently serving are role-exchanged.

[0207] In some embodiments, after receiving the first information, the third node determines whether to switch the wireless resource group currently serving configured by the third node or the primary wireless resource activated in the wireless resource group currently serving configured by the third node according to the first information, and sends feedback information to the second node, i.e., performs the following S402.

[0208] S402, the third node sends second information to the second node; correspondingly, the second node receives the second information sent by the third node. The second information is used to indicate the feedback information of the wireless resource group to be activated or switched by the third node.

[0209] In some embodiments, the second information includes at least one of the following: the indication information indicating whether to switch the wireless resource group currently serving configured by the third node; the indication information indicating whether to switch the primary wireless resource activated in the wireless resource group currently serving configured by the third node; the information of the wireless resource group configured by the third node selected by the third node to be activated or switched; the information of the wireless resource to be activated in the wireless resource group configured by the third node selected by the third node to be activated or switched; the bitmap of the index of the configuration of the wireless resource in the wireless resource group configured by the third node selected by the third node to be activated or switched.

[0210] S403, the second node generates the second signaling according to the first information and / or the second information.

[0211] It can be understood that the second node can determine the wireless resource group to be activated or switched according to the information (i.e., the first information and / or the second information) coordinated between the second node and the third node, and generate the second signaling, and then send the second signaling to the first node.

[0212] Exemplarily, the embodiment of the present disclosure needs inter-node coordination between the second node and the third node before sending the second signaling, so as to ensure that the wireless resource group simultaneously activated or applied by the first node does not exceed the limit of the maximum first node capability.

[0213] In some implementations, in the case that the second node is an MN node and the third node is an SN node, the activation or switching of the wireless resource group triggered by the MN node can be implemented as a1-a3.

[0214] a1, the MN sends information 1 to the SN; correspondingly, the SN receives the information 1 sent by the MN.

[0215] The information 1 is used to indicate the information of the wireless resource group selected by the MN to be activated or switched, and other auxiliary information.

[0216] In some embodiments, the information 1 includes at least one of the following:

[0217] The information of the primary wireless resource group selected by the MN to be activated or switched, such as the index or ID of the wireless resource group configuration, or the frequency point or frequency band information of the wireless resource in the wireless resource group; the number of wireless resources to be activated in the wireless resource group selected by the MN to be activated or switched; the list of frequency band combinations supported by the first node; the maximum number of activatable wireless resources in the secondary wireless resource group configured by the SN; and the indication information indicating whether the currently served primary wireless resource group and secondary wireless resource group are role-exchanged.

[0218] In some embodiments, after receiving the information 1, the SN determines whether to switch the currently served wireless resource group configured by the SN or the activated primary wireless resource in the currently served wireless resource group configured by the SN according to the information 1, and sends feedback information to the MN, i.e., performs the following a2.

[0219] a2, the SN sends information 2 to the MN; correspondingly, the MN receives the information 2 sent by the SN.

[0220] The information 2 is used to indicate the feedback information of the secondary wireless resource group to be activated or switched by the SN.

[0221] In some embodiments, the information 2 comprises at least one of the following: indication information for indicating whether to switch the secondary wireless resource group configured by the SN for the current service; indication information for indicating whether to switch the activated primary wireless resource in the secondary wireless resource group configured by the SN for the current service; information of the secondary wireless resource group configured by the SN selected by the SN to be activated or switched, such as an index or ID of the wireless resource group configuration, or frequency point or band information of the wireless resource in the wireless resource group; information of the wireless resource to be activated in the secondary wireless resource group configured by the SN selected by the SN to be activated or switched, such as an index or ID of the primary / secondary wireless resource configuration, or frequency point or band information of the primary / secondary wireless resource; a bitmap of indexes of configurations of the wireless resource in the secondary wireless resource group configured by the SN selected by the SN to be activated or switched, wherein each bit on the bitmap identifies an index representing a configuration of a wireless resource or a wireless resource group with the same index value, and each bit can be set to 0 or 1, wherein 0 represents that the wireless resource or the wireless resource group is deactivated or the configuration is not applied, and 1 represents that the wireless resource or the wireless resource group is activated or applied.

[0222] a3. The MN generates the second signaling according to the information 1 and / or the information 2.

[0223] Exemplarily, the MN generates the activation or switching signaling of the wireless resource group, such as according to the information of the wireless resource group selected by the MN and / or the feedback information of the SN (e.g., the information 1 and / or the information 2 described above). The MN sends the generated activation or switching signaling of the wireless resource group (i.e., the second signaling) to the first node. The second signaling comprises at least one of the coordination information contents between the MN and the SN described above.

[0224] In some implementations, in the case that the second node is an SN node and the third node is an MN node, the activation or switching of the wireless resource group triggered by the SN node can be implemented as b1-b3.

[0225] b1. The SN sends information 3 to the MN; correspondingly, the MN receives the information 3 sent by the SN.

[0226] The information 3 is used to indicate information of the wireless resource group selected by the SN to be activated or switched.

[0227] In some embodiments, the information 3 comprises at least one of the following: indication information for indicating that the SN requests to switch the secondary wireless resource group for the current service; indication information for indicating that the SN requests to switch the activated primary wireless resource in the secondary wireless resource group for the current service; information of the secondary wireless resource group selected by the SN to be activated or switched, such as an index or ID of the wireless resource group configuration, or frequency point or band information of the wireless resource in the wireless resource group; and a number of the wireless resource to be activated in the secondary wireless resource group selected by the SN to be activated or switched.

[0228] In some embodiments, after receiving information 3, the MN can accept or reject the activation or switching request of the secondary wireless resource group of the SN, or the activation or switching request of the primary wireless resource in the secondary wireless resource group. If the MN accepts the request, the MN can further decide whether to switch the currently served primary wireless resource group or the activated primary wireless resource in the currently served primary wireless resource group. The MN sends feedback information to the SN, i.e., performs b2.

[0229] b2, the MN sends information 4 to the SN; correspondingly, the SN receives the information 4 sent by the MN.

[0230] Information 4 is used to indicate the feedback information of the MN on the wireless resource group to be activated or switched.

[0231] In some embodiments, information 4 includes at least one of the following: indication information indicating whether to accept the activation or switching request of the secondary wireless resource group of the SN; indication information indicating whether to accept the activation or switching request of the primary wireless resource in the secondary wireless resource group of the SN; indication information indicating whether to switch the currently served primary wireless resource group; indication information indicating whether to switch the activated primary wireless resource in the currently served primary wireless resource group; information of the primary wireless resource group configured by the MN to be activated or switched selected by the MN; information of the wireless resource to be activated in the primary wireless resource group configured by the MN to be activated or switched selected by the MN; a bitmap of the index of the configuration of the wireless resource in the primary wireless resource group configured by the MN to be activated or switched selected by the MN; the maximum number of the activatable or switchable wireless resource in the secondary wireless resource group configured by the SN.

[0232] In some embodiments, according to the received feedback information of the MN, the SN can cancel or adjust the secondary wireless resource group to be activated or the wireless resource in the secondary wireless resource group to be activated, for example, the number of the activated wireless resource in the secondary wireless resource group does not exceed the maximum number indicated by the MN.

[0233] b3, the SN generates a second signaling according to information 3 and / or information 4.

[0234] Exemplarily, the SN generates an activation or switching command of the wireless resource group, such as according to the information of the activated wireless resource group selected by the SN and / or the feedback information of the MN (i.e., information 3 and / or information 4 described above). The SN sends the generated activation or switching signaling of the wireless resource group (i.e., the second signaling described above) to the first node. The activation or switching signaling contains at least one of the coordination information content between the MN and the SN described above.

[0235] In some embodiments, the network side performs inter-node coordination when preparing the configuration of the multiple radio resource groups, for example, before S301. The information exchanged between the second node and the third node in the coordination process can refer to the corresponding description in the embodiment shown in FIG. 8. The “to-be-activated or switched” in the above information can be replaced by “configured by the second node / third node”, i.e., the first / second information for coordination is the relevant information of the radio resource group or radio resource configuration provided by the second node / third node in the radio resource group configuration preparation stage. For example, the second node or the third node can generate the first signaling according to the first and / or second information for coordination.

[0236] In some embodiments, according to the result of the coordination between the second node and the third node, the second node or the third node does not need to further coordinate with the peer node when triggering the activation or switching of the multiple radio resource groups.

[0237] For example, the second node or the third node can divide the configured radio resource groups into multiple subsets, or divide the radio resources in one radio resource group into multiple subsets, such as one subset containing one or more radio resources (groups). The second node or the third node can determine whether to further perform inter-node coordination when triggering the activation or switching of the radio resources (groups) according to whether the activation or switching of the radio resources (groups) belongs to the activation or switching of the radio resources (groups) within the same subset. For example, when the activation or switching of the radio resources (groups) belongs to the activation or switching of the radio resources (groups) within the same subset, it will not affect the configured radio resources (groups) of the peer node. When the second node or the third node triggers the activation or switching of the radio resources (groups), it does not need to notify the peer node (i.e., inter-node coordination is not needed). When the activation or switching of the radio resources (groups) belongs to the activation or switching of the radio resources (groups) across subsets, it can affect the configured radio resources (groups) of the peer node. When the second node or the third node triggers the activation or switching of the radio resources (groups), it needs to notify the peer node (i.e., inter-node coordination is needed, for example, the relevant operations described in the embodiment of FIG. 8).

[0238] Exemplarily, the second node and the third node can associate the second node configured radio resource group or subset and the third node configured radio resource group or subset, for example, the associated second node configured radio resource group or subset and the third node configured radio resource group or subset can be activated or applied simultaneously, and the NW does not need to perform inter-node coordination when activating or switching the radio resource (group) among the associated radio resource groups or subsets. For example, when the second node triggers the activation or switching of the radio resource (group), if the radio resource groups or subsets before and after the switching are both associated with the currently serving or activated third node configured radio resource group or subset, the second node does not need to notify the opposite node (i.e., inter-node coordination is not needed). When the second node triggers the activation or switching of the radio resource (group), if the radio resource group or subset after the switching is not associated with the currently serving or activated third node configured radio resource group or subset, the second node needs to notify the opposite node (i.e., inter-node coordination is needed). Correspondingly, the third node triggered activation or switching of the radio resource (group) also follows the same principle.

[0239] In some embodiments, the above-mentioned radio resource or radio resource group can correspond to different states.

[0240] It can be understood that, in order to better manage the preconfigured at least one radio resource or radio resource group, in combination with the mobility management (such as continuous switching), power saving, fast activation or recovery of radio resources, etc. targets, different states can be defined for the radio resource or radio resource group, and through the conversion between the states, the related functions can be realized.

[0241] Exemplarily, the state corresponding to the radio resource or radio resource group can include at least one of the following:

[0242] Preconfigured state (or called candidate state): the first node stores / maintains the radio resource (group) configuration, but the radio resource (group) configuration is not applied / activated, and the first node can perform measurement (for example, layer 1 measurement and / or layer 3 measurement according to the reference signal (Reference Signal, RS) configuration of the radio resource (group)) or condition evaluation (for example, for activation or switching based on the execution condition) on the radio resource (group).

[0243] According to the configuration or indication of the network side (for example, the second node), the first node can also perform the operation in the partial activation state in the preconfigured state. For example, if the second node configures or indicates that radio link monitoring (Radio Link Monitoring, RLM) and / or beam failure monitoring (Beam Failure Detection, BFD) are allowed, the first node can also perform RLM / BFD on the radio resource (group).

[0244] Pre-configured suspended state (or called candidate suspended state): The first node stores or maintains the wireless resource (group) configuration, but the wireless resource (group) configuration is not applied / activated, and the first node stops / pauses the measurement or the execution of the condition evaluation on the wireless resource (group).

[0245] Activated state: The first node applies and activates the wireless resource (group) configuration. The first node can perform normal uplink or downlink communication on the wireless resource (group). For example, the first node can perform at least one of the following operations on the wireless resource (group): Sounding Reference Signal (SRS) transmission, Uplink Shared Channel (UL-SCH) data transmission, Physical Uplink Control Channel (PUCCH) transmission, Random Access Channel (RACH) procedure, Channel State Information (CSI) measurement / reporting procedure, Physical Downlink Control Channel (PDCCH) monitoring, Downlink Shared Channel (DL-SCH) data transmission, RLM, BFD.

[0246] Deactivated state: The first node applies but does not activate the wireless resource (group) configuration. The first node stops the uplink and / or downlink communication on the wireless resource (group). For example, the first node stops / pauses the operations in the activated state, or part of the operations (for example, according to the indication of the second node, the first node can continue part of the operations, such as RLM / BFD, in the deactivated state).

[0247] For the wireless resource (group) in the pre-configured state or the pre-configured suspended state, if the first node only stores / maintains the wireless resource (group) configuration, the first node capability will not be consumed (unless it is related to the maximum number of wireless resource (group) configurations that the first node can store / maintain). For the wireless resource (group) in the activated or deactivated state, the corresponding configuration and the operation behavior of the first node will consume the first node capability.

[0248] In some embodiments, when the first node receives the (candidate) wireless resource (group) configuration from the network side (for example, the second node), if the second node indicates the state of the wireless resource (group), the first node considers that the wireless resource (group) is in the state indicated by the second node.

[0249] The second node can indicate the status of the radio resource (group) in the radio resource (group) configuration, for example, by an indicator, such as a preconfigured status, a preconfigured suspended status, an activated status, a deactivated status.

[0250] In some embodiments, when the first node receives the (candidate) radio resource (group) configuration from the second node, if the second node does not indicate the status of the radio resource (group), the first node can consider the radio resource (group) to be in a certain status according to a default rule / definition, such as a preconfigured status, a preconfigured suspended status, an activated status, a deactivated status.

[0251] In some embodiments, the second node can send a dynamic activation or switching command to trigger the transition between the statuses, or the first node automatically triggers the transition between the statuses according to the execution condition preconfigured by the second node. Exemplarily, the transition between the statuses of the radio resource (group) can be as shown in FIG. 9.

[0252] In the following, the transition between the statuses of the radio resource (group) is described in an exemplary manner.

[0253] Example 1, transition between the preconfigured status and the preconfigured suspended status:

[0254] In some implementations, the second node can send dynamic signaling (such as RRC signaling, MAC CE signaling, DCI signaling) to instruct the first node to perform at least one of the following operations:

[0255] The first node activates or performs measurement and / or measurement reporting on the radio resource (group) in the preconfigured status or candidate status;

[0256] The first node deactivates, suspends or pauses the measurement and / or measurement reporting on the radio resource (group) in the preconfigured status or candidate status;

[0257] In some implementations, the second node can send dynamic signaling (such as RRC signaling, MAC CE signaling, DCI signaling) to indicate that the measurement resource (such as RS configuration) configured on the radio resource (group) is in an activated or deactivated status. For the deactivated measurement resource, the first node will not perform measurement (such as L1 measurement, and / or L3 measurement) and / or measurement reporting thereon.

[0258] In some implementations, the state transition is triggered automatically when the first node detects that a preconfigured condition of the second node is satisfied. For example, when it is detected that the measurement reference signal quality associated with the currently served radio resource (group) is lower than a preset threshold, the measurement and / or measurement reporting of other candidate radio resource (group) is activated automatically, i.e., the candidate radio resource (group) is transitioned from the preconfigured suspended state to the preconfigured state. Alternatively, when it is detected that the measurement reference signal quality associated with the currently served radio resource (group) is higher than a certain threshold, the measurement and / or measurement reporting of other candidate radio resource (group) is deactivated or stopped automatically, i.e., the candidate radio resource (group) is transitioned from the preconfigured state to the preconfigured suspended state.

[0259] Example II. Transition between the preconfigured state, the preconfigured suspended state, the activated state and the deactivated state:

[0260] In some implementations, the second node can send dynamic signaling (such as RRC signaling, MAC CE signaling, DCI signaling) to instruct the first node to activate one or more radio resources (groups). The first node activates the radio resource (group) indicated in the activation signaling according to the instruction of the second node. For the previously served or activated radio resource (group), the first node can switch it to the preconfigured state, the preconfigured suspended state or the deactivated state (for example, according to the instruction information of the second node).

[0261] In some implementations, the second node can indicate the identity of one or more radio resource (group) configurations and / or the state of the radio resource (group) in the dynamic signaling. The first node performs state transition according to the radio resource (group) and the corresponding state indicated by the second node.

[0262] In some implementations, the first node automatically triggers the state transition of the configured / candidate radio resource (group) when it detects that a preconfigured condition of the second node is satisfied. For example, when it is detected that the execution condition associated with the candidate radio resource (group) is satisfied (such as the measurement result of the radio resource (group) satisfies a certain measurement event), the first node automatically activates the radio resource (group), i.e., the candidate radio resource (group) is transitioned from the preconfigured state to the activated state.

[0263] In some implementations, the first node automatically triggers the state transition of the candidate radio resource (group) when it receives the RRC signaling sent by the second node or performs the RRC state transition. For example, when the first node receives the RRC release message, or when the first node enters the RRC idle state or the RRC inactive state from the RRC connected state, the radio resource (group) in the current activated state (and / or the deactivated state) is triggered to enter / transition to the preconfigured state (and / or the preconfigured suspended state).

[0264] In some implementations, the second node can also indicate the state of the candidate radio resource (group) in the transmitted RRC signaling (such as an RRC release message), and the first node performs the state transition of the radio resource (group) according to the state indicated by the second node.
