Description

Wireless network communication method and apparatus, storage medium and program product

[0001] The present application claims priority to Chinese Patent Application No. 202411030062.7, filed on July 29, 2024, the contents of which are incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present disclosure relates to the field of communication technology, and in particular, to a wireless network communication method and apparatus, a storage medium and a program product. BACKGROUND

[0003] A fifth generation mobile communication technology (5G) network (NW) manages user equipment (UE) by taking a cell as a basic unit. When the NW provides a radio resource control (RRC) signaling configuration for the UE, it takes a cell (Cell) as a granularity, and can provide a primary cell (PCell) configuration and one or more secondary cell (SCell) configurations. Multiple cell configurations are aggregated into a cell group, i.e., carrier aggregation (CA). Each cell can contain one downlink (DL) carrier and / or at most two associated uplink (UL) carriers. When the NW needs to update / switch a radio resource, for example, the configuration of the PCell or the SCell needs to be updated / switched, or the DL / UL configuration in a cell needs to be updated / switched, reconfiguration (such as through a switching process) needs to be performed through RRC signaling. This process will cause large signaling overhead and long switching / update delay, affecting communication performance. SUMMARY

[0029] 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.

[0030] 1. Carrier aggregation (CA)

[0031] After configuring CA, the UE establishes only one RRC connection with the network. At the time of RRC connection establishment / reestablishment / handover, one serving cell provides non-access stratum (NAS) mobility information, and at the time of RRC connection reestablishment / handover, one serving cell provides security input. This cell is called the primary cell (PCell). According to the function 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 the UE is always composed of one PCell and one or more SCells.

[0032] The reconfiguration, addition and deletion of SCell can be performed by RRC. During handover within the new radio (NR) system and during the recovery of connection from the RRC inactive state (RRC_INACTIVE), the network can also add, delete, retain or reconfigure SCells for use with the target PCell. When adding a new SCell, dedicated RRC signaling is used to send all the system information required by the SCell, that is, in the connected mode, the UE does not need to directly acquire the broadcast system information from the SCell.

[0033] The NW can configure up to 16 DL carriers and 16 UL carriers for CA for the UE.

[0034] 2. Bandwidth part (BWP)

[0035] 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.

[0036] 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.

[0037] 3. Multi-transmit / receive point (mTRP / multi-TRP)

[0038] In multi-TRP operation, a serving cell can schedule a UE from two TRPs, thereby 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).

[0039] 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 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.

[0040] 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 for 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.

[0041] 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.

[0042] 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 (physical cell identity) different from the serving cell PCI. At most one TCI state per activated TCI state can be associated with a PCI different from the serving cell PCI.

[0043] 4. Mobility enhancements techniques

[0044] 4.1. Conditional handover (CHO)

[0045] 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 satisfied. The user equipment starts evaluating the execution condition after receiving the CHO configuration and stops evaluating the execution condition after the handover is triggered. The CHO configuration includes candidate cell configuration generated by candidate target nodes and the execution condition of the corresponding candidate cell.

[0046] 4.2. Dual active protocol stack handover (DAPS HO)

[0047] To reduce the handover interruption time, 5G introduces 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.

[0048] 4.3. Layer 1 / layer 2 triggered mobility (L1 / L2 triggered mobility, LTM)

[0049] To reduce the handover interruption latency, reduce the handover signaling overhead, 5G introduces LTM. LTM is a procedure that the base station triggers cell handover through cell handover command based on media access control control element (MAC CE) signaling. The cell handover command indicates the LTM candidate cell configuration pre-configured by the base station through RRC signaling, and the UE switches to the corresponding target cell according to the handover command.

[0050] The overall procedure of LTM includes four parts: LTM preparation, advance synchronization, LTM cell handover execution and LTM cell handover completion. Continuous LTM can reuse the pre-configured 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.

[0051] For future wireless communication systems (e.g., 6G), the concept of cell can 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 can be weakened / removed in the related communication architecture, and carrier or bandwidth part (BWP) can be used instead of cell. For example, cell-level resource configuration can be replaced by carrier-level or BWP-level resource configuration in RRC 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) carrier and downlink (DL) carrier can also be supported. This flexible carrier / BWP aggregation manner can reduce signaling overhead, reduce carrier / BWP activation / switching delay, and / or improve spectrum utilization.

[0052] The scheme of the embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0053] 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, and the like, which are not limited by the embodiments of the present disclosure.

[0056] In the disclosure, the "first" node, the "second" node, the "first" manner, the "second" manner, the "first" method, the "second" method, the "first" matrix, the "second" matrix, the "first" part, and the "second" part are only used for description without special indication, and do not represent the front or back or the order.

[0057] In the embodiments of the disclosure, the first node and the second node can also have other names. For example, the first node can also be referred to as a first communication node, and the second node can also be referred to as a second communication node. The embodiments of the disclosure do not limit this.

[0058] In some embodiments, the base station described above can be any one of an evolution node B (eNB), a next generation node B (gNB), a transmission and reception point or transmit / receive point (TRP), a transmission point (TP), a relay node, a reconfigurable intelligent surface (RIS), and some other access node. According to the size of the service coverage area provided, the base station can be further classified into a macro base station for providing a macro cell, a micro base station for providing a micro cell, and a femto base station for providing a femto cell. As wireless communication technologies continue to evolve, future base stations can also be referred to by other names.

[0059] In some embodiments, the terminal described above can be a device with wireless transceiving functions, such as a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), an Internet of Things terminal, and the like. The embodiments of the present disclosure do not limit the type of terminal.

[0060] 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 are 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.

[0061] Next, as shown in FIG. 2, the embodiments of the present disclosure provide a wireless network communication method, which is applied to a first node. The first node can be the first node 110 shown in FIG. 1 described above. The method includes the following S101 and S102.

[0062] In S101, the first signaling is received.

[0063] In some embodiments, in order to facilitate the first node to timely switch / activate the wireless resource in the case that the wireless resource switching / activation condition is met, without reconfiguration through RRC signaling, the second node sends the first signaling to the first node. Correspondingly, the first node receives the first signaling from the second node. The first signaling is used to configure at least one wireless resource, and the second node is a network side device, for example, the second node 120 shown in FIG. 1.

[0064] In some embodiments, the first signaling includes an RRC message or system information (SI). The configuration of the wireless resource can be a candidate configuration of the wireless resource, and each configuration of the wireless resource is associated with a configuration identifier, for example, a configuration index, an identity number (ID), etc.

[0065] In some embodiments, the wireless resource includes at least one of a cell resource, a carrier resource, or a bandwidth part (BWP) resource, that is, the wireless resource can be at least one of a cell, a carrier, or a bandwidth part.

[0066] In some embodiments, the wireless resource includes at least one of a primary wireless resource, a secondary wireless resource, an uplink wireless resource, or a downlink wireless resource. Taking the wireless resource as a cell for example, the wireless resource includes at least one of a primary cell, a secondary cell, an uplink cell, or a downlink cell. Taking the wireless resource as a carrier for example, the wireless resource includes at least one of a primary carrier, a secondary carrier, an uplink carrier, or a downlink carrier. Taking the wireless resource as a bandwidth part for example, the wireless resource includes at least one of a primary bandwidth part, a secondary bandwidth part, an uplink bandwidth part, or a downlink bandwidth part.

[0067] 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.

[0068] PSCell definition: the primary cell in the secondary cell group (SCG), for dual connectivity (DC) operation, the UE performs random access on this cell when performing a synchronization reconfiguration process.

[0069] SCell definition: for a UE configured with CA, SCell can provide additional wireless resources based on SpCell.

[0070] Compared with the SCell, the SpCell additionally has the functions of providing NAS mobility information, RRC re-establishment, security input, cell radio network temporary identifier (C-RNTI) allocation, and the like.

[0071] As can be seen from the above description of the cell, with the development of communication technology, a carrier or a bandwidth part may be used instead of a 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 for description. It should be noted that the carrier described below can also be replaced by a cell or a bandwidth part or other similar functional wireless resources.

[0072] Based on the carrier, it includes 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 is the carrier on which the UE can perform initial connection establishment or initiate a re-establishment process. 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 C-RNTI) allocation of wireless resources. 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.

[0073] For dual / multi-connectivity operation, the primary carrier can contain / represent the primary carrier in the master carrier group (master carrier group) and / or the primary carrier in the secondary carrier group (secondary carrier group). The primary carrier in the secondary carrier group can also be referred to as a "primary secondary carrier", that is, the UE performs random access on this carrier when performing a synchronization reconfiguration process.

[0074] The master carrier group is a group of carriers associated with a master node (MN), which contains the above-mentioned primary carrier and / or secondary carrier. The secondary carrier group is a group of carriers associated with a secondary node (SN), which contains the above-mentioned primary secondary carrier and / or secondary carrier.

[0075] 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 through the first signaling. The second node can pre-configure multiple wireless resource configurations for the first node through the first signaling. The first node can autonomously select and apply / activate one or more wireless resources based on the indication of the second node or based on the execution condition of the pre-configuration of the second node. The indication of the second node can be sent through RRC signaling, MAC CE, or DCI signaling, etc. The execution condition of the pre-configuration of the second node can include measurement configuration associated / corresponding to the wireless resource, measurement event, signal quality threshold, data flow threshold, etc. The first node can automatically activate / apply or deactivate / disable the corresponding wireless resource according to whether the execution condition associated / corresponding to the wireless resource is met.

[0076] In some embodiments, the first signaling includes configuration of at least one wireless resource group, and the configuration of the wireless resource group includes configuration of each wireless resource in the wireless resource group.

[0077] Taking wireless resources as carriers as an example, the second node configures one or more carrier groups, and each carrier group includes configuration of multiple carriers. The configuration of each carrier can include configuration similar to serving cell configuration (ServingCellConfig), such as configuration including frequency domain bandwidth range, reference signal (RS), common channel, dedicated channel, BWP, multi-TRP (multi-TRP, or mTRP), and / or measurement, etc.

[0078] 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.

[0079] 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 used as 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 used as 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 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, and the second indication information is used to indicate that the configuration of the wireless resource is activated or applied as a primary wireless resource and / or a secondary wireless resource. For example, for each carrier in the common carrier group, the first 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 (e.g., a time division duplex carrier), and the second 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.

[0080] 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 an RRC configuration or a dynamic activation / switching command, for example, by associating the uplink wireless resources and the downlink wireless resources through UL / DL wireless resource indexes / identifiers.

[0081] 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.

[0082] 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: 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.

[0083] 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.

[0084] 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.

[0085] In some embodiments, one or more BWPs can also be configured under each carrier.

[0086] Taking wireless resources as an example, referring to FIG. 3, it is a schematic diagram of a multi-carrier configuration framework according to an embodiment of the present disclosure. The second node can provide an RRC configuration (such as through an RRC reconfiguration message or a system message). One 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, RLC / MAC configuration, and common carrier configuration. One carrier can be associated with one or more mTRPs.

[0087] Taking wireless resources as an example, referring to FIG. 4, it is a schematic diagram of a multi-bandwidth part configuration framework according to an embodiment of the present disclosure. The second node can provide an RRC configuration (such as through an RRC reconfiguration message or a system message). One 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.

[0088] In some embodiments, the configuration of the radio resource group includes common configuration and dedicated configuration of each radio resource. The common configuration can be the same configuration or reference configuration commonly used by each radio resource in the radio resource group, and the dedicated configuration can be a differential configuration or an incremental configuration based on the reference configuration of each radio resource in the radio resource group.

[0089] In some embodiments, each wireless resource group can contain or associate with one common configuration (i.e. a configuration applicable to a common part of different wireless resources in the same wireless resource group, such as a common physical parameter configuration) and one or more dedicated configurations of the wireless resources (such as dedicated channel configuration, radio link monitoring (RLM) configuration, beam failure recovery configuration, multi-TRP configuration, and / or transmission configuration indication state (TCI-state) configuration, etc.). When the second node indicates to activate / apply a certain wireless resource or the first node selects to activate / apply a certain wireless resource, the first node applies the common configuration of the wireless resource group to which the wireless resource belongs and the dedicated configuration of the wireless resource.

[0090] In some embodiments, each wireless resource group can contain or associate with one reference configuration (such as a configuration template or a common part configuration of multiple wireless resources) and one or more configurations of the wireless resources (such as a complete configuration or an incremental configuration). The second node can indicate whether each wireless resource configuration is a complete configuration or an incremental configuration. When the second node indicates to activate / apply a certain wireless resource or the first node selects to activate / apply a certain wireless resource, if the configuration of the wireless resource is a complete configuration, the first node applies the complete configuration; if the configuration of the wireless resource is an incremental configuration, the first node applies / stacks the incremental configuration on the basis of the reference configuration to generate a complete configuration, and then the first node applies the generated complete configuration.

[0091] In some embodiments, the configuration of a wireless resource group includes multiple sets of configurations of the wireless resources in the wireless resource group, and each set of configurations of a wireless resource is a configuration of the wireless resource under different purposes.

[0092] As an example, the multiple sets of configurations of a wireless resource include a first configuration and a second configuration, the first configuration is used to determine the configuration of the wireless resource as a primary wireless resource, and the second configuration is used to determine the configuration of the wireless resource as a secondary wireless resource; or the multiple sets of configurations of a wireless resource include a third configuration, a fourth configuration and a fifth configuration, the third configuration and the fourth configuration are jointly used to determine the configuration of the wireless resource as a primary wireless resource, and the third configuration and the fifth configuration are jointly used to determine the configuration of the wireless resource as a secondary wireless resource. The third configuration can be understood as a general configuration of the wireless resource, the fourth configuration can be understood as an additional configuration to be applied when the wireless resource is a primary wireless resource, and the fifth configuration can be understood as an additional configuration to be applied when the wireless resource is a secondary wireless resource.

[0093] For example, the additional configuration applied for the primary wireless resource can include: related configuration information for radio link failure (RLF) detection (e.g., values of timers or counters for RLF detection, reference signal configuration for RLF detection, etc.), a radio network temporary identifier (e.g., C-RNTI) value of the wireless resource, and / or a timer value for wireless resource activation / switching, etc.; the additional configuration applied for the secondary wireless resource can include: a secondary wireless resource activation status indication, and / or a dormant wireless resource configuration, etc.

[0094] The first node can select / determine which set of configuration to apply according to the indication of the second node in the second signaling. For example, if the wireless resource is activated as a primary wireless resource, the first node can apply the configuration of the wireless resource as a primary wireless resource, or the first node applies / stacks the additional configuration of the primary wireless resource on top of the general configuration (if the additional configuration is provided by the second node); if the wireless resource is activated as a secondary wireless resource, the first node can apply the configuration of the wireless resource as a secondary wireless resource, or the first node applies / stacks the additional configuration of the secondary wireless resource on top of the general configuration (if the additional configuration is provided by the second node).

[0095] 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 (such as indicating 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 (such as SSB or channel state information-reference signal (CSI-RS) configuration for synchronization and channel state measurement), or a wireless resource subset can contain a set of common downlink reference signal information; this 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 (such as MAC CE or DCI), or the first node can flexibly select the paired UL wireless resources according to the measurement of the DL wireless resources (for example, in the initial access stage). The above-mentioned wireless resource subset can be applied to the functions of multi-band service cell (MBSC) or multi-band aggregation.

[0096] In some embodiments, referring to FIG. 5, another multi-carrier configuration framework according to an embodiment of the present disclosure is shown. The bandwidth part group can also be contained under the 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 service cell (MBSC)).

[0097] 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.

[0098] In some embodiments, the multiple wireless resources in the same wireless resource group belong to the same MAC management.

[0099] The above embodiments are described for the configuration of wireless resources, in some embodiments, the wireless resources or wireless resource groups have associated at least one TRP.

[0100] It should be understood that for the configuration of mTRP, the concept of intra-cell mTRP can be extended to mTRP within the same wireless resource, for example, intra-carrier mTRP and intra-BWP mTRP; the concept of inter-cell mTRP can be extended to mTRP between different wireless resources or across wireless resources, for example, inter-carrier mTRP and inter-BWP mTRP.

[0101] Taking the carrier as an example of wireless resource, for intra-carrier mTRP, the TRP (such as TCI-state) under each carrier (such as under each carrier BWP) can be configured, and the second node can dynamically activate the TRP under each carrier through signaling (such as RRC signaling, MAC CE, or DCI).

[0102] For inter-carrier mTRP, a common TRP configuration resource pool can be introduced, which contains the TRP configuration information associated with all carriers in the carrier group. The second node can dynamically activate part of the TRPs in the common resource pool as the inter-carrier mTRP of the current serving carrier through signaling (such as RRC signaling, MAC CE, or DCI).

[0103] In some embodiments, the TRP configuration in the common TRP resource configuration pool can be used for inter-carrier mTRP and / or intra-carrier mTRP. One or more TRP configuration identifiers / indexes associated / contained in the carrier configuration are used to indicate the corresponding TRP configuration in the common TRP resource configuration pool. One indication information associated / contained in the carrier configuration is also used to indicate the type of TRP associated with the carrier, for example, inter-carrier mTRP and / or intra-carrier mTRP.

[0104] That is, the wireless resources or wireless resource groups have associated at least one TRP belonging to a common TRP configuration set, and the common TRP configuration set includes the configurations of the TRPs associated with the multiple wireless resources contained in the wireless resource group.

[0105] In some embodiments, the configuration of the TRP comprises at least one of: an identity of the TRP; an identity of a radio resource associated with the TRP; a configuration parameter of a reference signal; an identity of the reference signal; a synchronization signal block measurement timing configuration (SMTC), such as comprising a measurement period, ssb-PositionsInBurst, and / or ss-PBCH-BlockPower; a configuration parameter of a transmission configuration indication state; an identity of the transmission configuration indication state; a type of the transmission configuration indication state, such as a DL / UL separated TCI-state, or a joint TCI-state; an uplink power control parameter; an identity of a configured uplink power control.

[0106] It should be noted that the identity referred to in the above embodiments can be an index, an identity number (ID), etc. The reference signal comprises at least one of an SSB, a CSI-RS, a CSI-RS for tracking (TRS), and a positioning reference signal (PRS).

[0107] In some embodiments, referring to FIG. 6, a schematic diagram of an mTRP configuration framework according to an embodiment of the present disclosure is provided. The second node can provide an RRC configuration (e.g., through an RRC reconfiguration message, or a system message). The RRC configuration can comprise at least one of a radio bearer configuration, a carrier group configuration, and a measurement configuration. The carrier group configuration comprises a configuration of a common mTRP group, a configuration of one or more carriers, an RLC / MAC configuration, and a general carrier configuration. The configuration of the common mTRP group comprises a configuration of one or more mTRPs, and the configuration of one carrier can be associated with the configuration of one or more mTRPs (e.g., by indicating the associated one or more mTRP configurations of the common mTRP group through an mTRP configuration identity / index).

[0108] In some embodiments, a radio resource or a radio resource group has at least one associated radio bearer configuration.

[0109] 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.

[0110] The second node can be pre-configured with multiple sets of radio bearer configurations. Each set of radio bearer configurations is associated with / contains an identifier of a radio bearer configuration.

[0111] In S102, based on a preset condition, a target radio resource in the at least one radio resource is activated or deactivated.

[0112] For ease of description, the following embodiments are described by taking an example of activating a target radio resource in the at least one radio resource based on a preset condition.

[0113] As an example, the preset condition includes at least one of condition 1 and condition 2.

[0114] Condition 1: receiving a second signaling, the second signaling being used to indicate to activate / apply / switch or deactivate the target radio resource.

[0115] In some embodiments, receiving the second signaling can be receiving the second signaling from the second node. That is, in the case that the second node needs the first node to activate / switch the radio resource, the second node sends the second signaling to the first node. Accordingly, the first node receives the second signaling from the second node. Accordingly, the first node activates / applies or deactivates the target radio resource indicated in the second signaling and / or related information.

[0116] In some embodiments, the second signaling includes L1 signaling (such as DCI), L2 signaling (such as MAC CE) or L3 signaling (such as RRC message).

[0117] In some embodiments, the second signaling comprises at least one of the following: an identification / index of the target wireless resource; an identification / index of a target wireless resource group or a target wireless resource subgroup, which can be used to indicate that all wireless resources contained in the target wireless resource group or the target wireless resource subgroup are activated / applied; a radio network temporary identification of the target wireless resource; an identification / index of a wireless bearer configuration associated with the target wireless resource; an identification / index of a TRP associated with the target wireless resource; indication information indicating whether the target wireless resource is activated or deactivated; indication information indicating whether the target wireless resource is a primary wireless resource or a secondary wireless resource; indication information indicating a primary wireless resource in the target wireless resource; indication information indicating a secondary wireless resource in the target wireless resource; indication information indicating an identification of a wireless resource associated with the target wireless resource in an opposite transmission direction; indication information indicating whether to perform a random access (RA) procedure on the target wireless resource, which can be an explicit indication (such as an indicator of whether to perform RACH) or an implicit indication (such as the second node carrying maximum timing advance (TA) information of the target wireless resource in the second signaling, so that the first node can directly apply the received TA information in the process of activating the target wireless resource, without the need to perform a RACH procedure to obtain TA information and complete uplink synchronization); maximum TA information or compensation TA information of the target wireless resource.

[0118] As an example, the second signaling can further comprise at least one of the following: in the case of the target wireless resource being a carrier, an identification of an activated uplink BWP and / or an identification of an activated downlink BWP under the target carrier; an identification / index of a TCI state of 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.; relevant information required for performing a random access on the target wireless resource, for example, an uplink wireless resource (such as an UL carrier, an UL BWP) on which the first node performs a random access channel (RACH) procedure (such as relevant information including an identification of the target wireless resource), a random access preamble index, an SSB reference signal index (such as a RACH occasion used to determine a physical random access channel (PRACH) transmission), and / or a PRACH mask index (used to indicate a RACH occasion associated with the above-mentioned SSB), etc.

[0119] Condition 2: The target wireless resource satisfies the corresponding execution condition for activation or deactivation.

[0120] In some embodiments, the target wireless resource satisfying the corresponding execution condition for activation or deactivation can be pre-configured by the second node, indicated by the second node, or pre-agreed by the first node and the second node. The execution condition includes at least one of the following: a measurement configuration associated / corresponding to the wireless resource, a measurement event, a signal quality threshold, a data traffic threshold, etc. The first node can automatically activate / apply or deactivate the configuration of the corresponding target wireless resource according to whether the corresponding execution condition is satisfied, for example, a mechanism similar to conditional handover (CHO).

[0121] It should be understood that condition 1 above is for the second node to instruct the first node to perform switching / activation of the wireless resource, and condition 2 is for the first node to autonomously perform switching / activation of the wireless resource.

[0122] In some embodiments, the first node can further determine whether to perform the random access procedure on the target wireless resource according to at least one of the following: whether the maximum time advance information of the target wireless resource is acquired; and whether the target wireless resource and the currently activated or applied wireless resource belong to the same wireless resource group or the same wireless resource subgroup.

[0123] As an example, when the first node performs switching / activation of the wireless resource, in the case where the maximum time advance information of the target wireless resource has been acquired (for example, acquired through the maximum time advance information of the target wireless resource carried in the second signaling, or acquired through the maximum time advance measurement based on the first node), it is determined that the random access procedure on the target wireless resource is not needed; or in the case where the maximum time advance information of the target wireless resource is not acquired, it is determined that the random access procedure on the target wireless resource is needed.

[0124] As an example, when the first node performs switching / activation of the wireless resource, in the case where the target wireless resource and the currently activated or applied wireless resource belong to the same wireless resource group or the same wireless resource subgroup (for example, the maximum time advance of the wireless resources in the same wireless resource group or the same wireless resource subgroup is the same), it is determined that the random access procedure on the target wireless resource is not needed; or in the case where the target wireless resource and the currently activated or applied wireless resource do not belong to the same wireless resource group or the same wireless resource subgroup, it is determined that the random access procedure on the target wireless resource is needed.

[0125] In some embodiments, the first node can determine whether the target wireless resource and the currently activated or applied wireless resource belong to the same wireless resource group or the same wireless resource subgroup according to a relevant configuration identification (ID) of the wireless resource. For example, when the maximum time advance related configuration ID (or random access related configuration ID) of the target wireless resource is the same as the maximum time advance related configuration ID (or random access related configuration ID) of the currently activated or applied wireless resource, the two belong to the same wireless resource group or the same wireless resource subgroup; otherwise, the two do not belong to the same wireless resource group or the same wireless resource subgroup.

[0126] In some embodiments, the wireless resource or the wireless resource group has an associated wireless network temporary identifier, for example, a C-RNTI. When the target wireless resource is activated as a primary wireless resource, the first node applies the wireless network temporary identifier of the target wireless resource. When the target wireless resource is activated as a secondary wireless resource, the first node ignores the wireless network temporary identifier of the target wireless resource.

[0127] In some embodiments, the wireless resources in the same wireless resource group share the same wireless network temporary identifier.

[0128] In some embodiments, the first node can determine whether to apply or update the wireless network temporary identifier according to at least one of the following: whether the wireless network temporary identifier of the target wireless resource is acquired; whether the target wireless resource and the currently activated or applied wireless resource belong to the same wireless resource group or the same wireless resource subgroup.

[0129] As an example, when the first node performs switching / activation of the wireless resource, in the case where the wireless network temporary identifier of the target wireless resource is acquired (for example, acquired through the wireless network temporary identifier of the target wireless resource carried in the second signaling), it is determined to apply or update the wireless network temporary identifier, that is, the first node applies the wireless network temporary identifier of the target wireless resource. Or, in the case where the wireless network temporary identifier of the target wireless resource is not acquired, the first node determines not to apply or update the wireless network temporary identifier, that is, the currently applied wireless network temporary identifier remains unchanged.

[0130] As an example, when the first node performs the switching / activation of the radio resource, in the case that the target radio resource and the currently activated or applied radio resource belong to the same radio resource group or the same radio resource subgroup (e.g., the radio network temporary identifiers of the radio resources in the same radio resource group or the same radio resource subgroup are the same), it is determined that the radio network temporary identifier is not applied or updated, i.e., the currently applied radio network temporary identifier is kept unchanged. Or, in the case that the target radio resource and the currently activated or applied radio resource do not belong to the same radio resource group or the same radio resource subgroup, the first node determines to apply or update the radio network temporary identifier, i.e., the first node applies the radio network temporary identifier of the target radio resource.

[0131] In some embodiments, the first node can determine whether the target radio resource and the currently activated or applied radio resource belong to the same radio resource group or the same radio resource subgroup according to the related configuration identifiers (IDs) of the radio resources. For example, when the radio network temporary identifier related configuration ID of the target radio resource is the same as the radio network temporary identifier configuration related ID of the currently activated or applied radio resource, they belong to the same radio resource group or the same radio resource subgroup; otherwise, they do not belong to the same radio resource group or the same radio resource subgroup.

[0132] In some embodiments, the first node determines whether to apply or update the radio bearer configuration according to at least one of the following: whether the identifier of the radio bearer configuration associated with the target radio resource is acquired; whether the target radio resource and the currently activated or applied radio resource belong to the same radio resource group or the same radio resource subgroup.

[0133] As an example, when the first node performs the switching / activation of the radio resource, in the case that the identifier of the radio bearer configuration associated with the target radio resource is acquired (e.g., acquired through the identifier of the radio bearer configuration of the target radio resource carried in the second signaling), it is determined to apply or update the radio bearer configuration, i.e., the first node applies the radio bearer configuration associated with the target radio resource. Or, in the case that the identifier of the radio bearer configuration associated with the target radio resource is not acquired, the first node determines not to apply or update the radio bearer configuration, i.e., the currently applied radio bearer configuration is kept unchanged.

[0134] As an example, when the first node performs switching / activation of a radio resource, in a case that the target radio resource and the currently activated or applied radio resource belong to the same radio resource group or the same radio resource subgroup (e.g., the radio resources in the same radio resource group or the same radio resource subgroup have the same radio bearer configuration), it is determined that the radio bearer configuration is not applied or updated, i.e., the currently applied radio bearer configuration is kept unchanged. Or, in a case that the target radio resource and the currently activated or applied radio resource do not belong to the same radio resource group or the same radio resource subgroup, the first node determines to apply or update the radio bearer configuration, i.e., the first node applies the radio bearer configuration associated with the target radio resource.

[0135] In some embodiments, in a case that the target radio resource and the currently activated or applied radio resource belong to the same radio resource group or the same radio resource subgroup, the first node does not need to perform L2 reset related operations, such as PDCP re-establishment, PDCP data recovery, RLC re-establishment, and / or MAC reset (or MAC partial reset) operations, in the process of switching / activating the target radio resource. In a case that the target radio resource and the currently activated or applied radio resource do not belong to the same radio resource group or the same radio resource subgroup, the first node needs to perform at least one of the L2 reset related operations, such as PDCP re-establishment, PDCP data recovery, RLC re-establishment, or MAC reset (or MAC partial reset) operations, in the process of switching / activating the target radio resource.

[0136] In some embodiments, the first node can determine whether the target radio resource and the currently activated or applied radio resource belong to the same radio resource group or the same radio resource subgroup according to the relevant configuration identification (ID) of the radio resource. For example, when the radio bearer related configuration ID (or L2 reset related configuration ID) of the target radio resource and the radio bearer related configuration ID (or L2 reset related configuration ID) of the currently activated or applied radio resource are the same, they belong to the same radio resource group or the same radio resource subgroup; otherwise, they do not belong to the same radio resource group or the same radio resource subgroup.

[0137] In some embodiments, the first node activating / applying / switching or deactivating the target wireless resource in the at least one wireless resource based on the preset condition can comprise at least one of the following operations: applying / activating the configuration of the target wireless resource indicated by the second node or selected by the first node; applying / activating the configuration of the target wireless resource group or the target wireless resource subgroup indicated by the second node or selected by the first node; applying / activating the TCI state of the target wireless resource, for example, if the TCI state information of the target wireless resource to be activated / applied is indicated in the second signaling or provided by the second node; applying / activating the wireless bearer configuration associated with the target wireless resource, for example, if the wireless bearer configuration information associated with the target wireless resource to be activated / applied is indicated in the second signaling or provided by the second node; applying the TA value of the target wireless resource indicated by the second node or selected by the first node or applying the compensation TA value based on the current TA value, for example, if the relevant TA information of the target wireless resource to be activated / applied is indicated in the second signaling or provided by the second node or the first node has obtained the valid TA information of the target wireless resource to be activated / applied; applying the wireless network temporary identifier (such as C-RNTI) value of the target wireless resource indicated by the second node or selected by the first node, for example, if the wireless network temporary identifier of the target wireless resource to be activated / applied is indicated in the second signaling or provided by the second node; starting a timer for monitoring the target wireless resource activation / switching process.

[0138] If the wireless resource is not within the range of the activated / applied target wireless resource indicated by the second node or selected by the first node, the current serving wireless resource is deactivated or disabled. If the second node indicates to deactivate the target wireless resource, the indicated target wireless resource is deactivated or disabled; the connection with the current serving wireless resource is disconnected, synchronized and / or accessed to the target wireless resource indicated by the second node or selected by the first node. A random access process is initiated to access the target wireless resource 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 wireless resource activation / switching process needs to perform a random access process, or the uplink synchronization process between the first node and the target wireless resource is not performed / completed; or the first node does not obtain the TA of the target wireless resource in advance.

[0139] If the first node does not need to initiate the random access procedure, the first node can receive an uplink grant (UL grant) by monitoring the PDCCH scheduling of the target wireless resource indicated by the second node or selected by the first node, to send an uplink signal through the uplink grant, or send an uplink signal to the target wireless resource indicated by the second node or selected by the first node according to a configured grant pre-configured by the second node, for example, the first node can select an associated configured grant slot to send an uplink signal according to the TCI state information of the target wireless resource indicated in the second signaling.

[0140] 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 wireless resource 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 wireless resource. The uplink signal can include information of the activated / applied target wireless resource, such as an identifier / index of the target wireless resource, an identifier / index of a target wireless resource group or a target wireless resource subgroup, an identifier / index of a wireless bearer configuration associated with the target wireless resource, and / or an identifier / index of a TRP associated with the target wireless resource, etc.

[0141] Based on the embodiment shown in FIG. 2, the second node pre-configures at least one wireless resource through the first signaling, so that the first node can activate or deactivate a target wireless resource in the at least one wireless resource based on a preset condition. In this way, by pre-configuring the at least one wireless resource, the target wireless resource can be directly activated or deactivated to complete the switching of the wireless resource when the preset condition is met, i.e., when the wireless resource needs to be switched, without the need for reconfiguration through RRC signaling, thereby reducing the signaling overhead of switching the wireless resource and reducing the latency of wireless resource switching / activation, which helps to improve the spectrum utilization.

[0142] In some embodiments, as shown in FIG. 7, the embodiment of the present disclosure 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. The wireless network communication method can include the following: S201, sending a first signaling.

[0143] In some embodiments, in order to reduce the signaling overhead of the first node switching the wireless resource, the second node sends a first signaling to the first node. The first signaling is used to configure at least one wireless resource.

[0152] 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 is a same configuration or a reference configuration commonly used by each wireless resource in the wireless resource group, and the dedicated configuration is a differential configuration or an incremental configuration based on the reference configuration of each wireless resource in the wireless resource group.

[0153] In some embodiments, the configuration of the wireless resource group comprises the configuration of at least one wireless resource subgroup, and the configuration of the wireless resource subgroup comprises the configuration of one or more wireless resources in the wireless resource group.
