Referring to fig. 1, a schematic structural diagram of a wireless communication system according to an embodiment of the disclosure is shown. As shown in fig. 1, the wireless communication system is a communication system based on a cellular mobile communication technology, and may include: a number of UEs 11 and a number of network devices 12.

Wherein the wireless communication system may be a fourth generation mobile communication technology (the 4th generation mobile communication,4G) system, also known as a long term evolution (Long Term Evolution, LTE) system; alternatively, the wireless communication system may be a 5G system, also known as a New Radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next generation system of the 5G system. Among them, the access network in the 5G system may be called NG-RAN (New Generation-Radio Access Network, new Generation radio access network). Or, an MTC system.

Wherein UE 11 may be a device that provides voice and/or data connectivity to a user. The UE 11 may communicate with one or more core networks via a radio access network (Radio Access Network, RAN), and the UE 11 may be an internet of things UE such as a sensor device, a mobile phone (or "cellular" phone) and a computer with an internet of things UE, for example, a fixed, portable, pocket, hand-held, computer-built-in or vehicle-mounted device. Such as a Station (STA), subscriber unit (subscriber unit), subscriber Station (subscriber Station), mobile Station (mobile Station), mobile Station (mobile), remote Station (remote Station), access point, remote UE (remote terminal), access UE (access terminal), user terminal, user agent (user agent), user device (user equipment), or user UE (UE). Alternatively, the UE 11 may be an unmanned aerial vehicle device. Alternatively, the UE 11 may be a vehicle-mounted device, for example, a laptop with a wireless communication function, or a wireless communication device externally connected to the laptop. Alternatively, the UE 11 may be a roadside device, for example, a street lamp, a signal lamp, or other roadside devices having a wireless communication function.

Network device 12 may include an access network device. Optionally, the network device 12 may also include a core network device. The access network device may be an evolved access device (eNB) employed in a 4G system. Alternatively, an access device (gNB) employing a centralized and distributed architecture in a 5G system may be used. When the access network device adopts a centralized and distributed architecture, it generally includes a Central Unit (CU) and at least two Distributed Units (DUs). A protocol stack of a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer, a radio link layer control protocol (Radio Link Control, RLC) layer, and a medium access control (Media Access Control, MAC) layer is provided in the centralized unit; a Physical (PHY) layer protocol stack is disposed in the distribution unit, and a specific implementation manner of the access network device according to the embodiments of the present disclosure is not limited.

A wireless connection may be established between the network device 12 and the UE 11 over a wireless air interface. In various embodiments, the wireless air interface is a fourth generation mobile communication network technology (4G) standard-based wireless air interface; or, the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; alternatively, the wireless air interface may be a wireless air interface based on a 5G-based technology standard of a next generation mobile communication network.

After introduction of the 3GPP standard release 18 (R18) Redcap user, the peak rate is further reduced. For example, a BW3 (i.e. supporting bandwidth reduction scheme 3) type UE, where the scheduling for the data channel is reduced to 5M bandwidth, but the control channel is maintained at 20M while peak rate reduction is performed, i.e. supporting PR1 (peak rate reduction scheme 1) scheme, such a terminal is called Rel-18 eRedCap UE capable of BW3/pr3+pr1:

the 5MHz baseband bandwidth is only used for physical Downlink shared channels (Physical Downlink Shared Channel, PDSCH) (for unicast and broadcast) and physical Uplink shared channels (Physical Uplink Shared Channel, PUSCH), and the radio frequency bandwidth for Uplink (UL) and Downlink (DL) is 20MHz. Other physical channels and signals are still allowed to use up to 20MHz of radio frequency plus baseband partial Bandwidth (BWP).

The hardware of the Redcap user of 3GPP standard release 17 (R17) implements the peak rate reduction requirement of the eRedcap of R18. I.e. Rel-18 eRedCap UE capable of 20MHz+PR1 or Rel-18 eRedCAP PR1 type UEs are introduced.

There are two peak rate reducing UEs in the network, namely Rel-18 eRedCap:UE capable of BW3/pr3+pr1 (first type of UE) and Rel-18 eRedCap UE capable of 20MHz+PR1 (second type of UE).

When the core network needs to send data to the UE, sending a PAGING (PAGING) message to the base station; and the base station sends a PAGING (PAGING) message to a cell belonging to a Tracking Area (TA) list according to the TA list information in the PAGING message sent by the core network, and the UE receives the PAGING message sent by the eNB at the PAGING occasion of the UE. Typically one TA may span multiple base stations or multiple cells under multiple base stations.

If a base station does not support a certain type, such as eRedcap user access for R18, then if the type of UE cannot camp, it is not known from the core network and continues to send paging messages for the UE within TA range. This increases unnecessary signaling overhead between the core network to the base station.

Therefore, how to report the UE types that the base station can support to the core network by the base station, and reduce ineffective signaling overhead between the core network and the base station, such as paging signaling overhead, is a problem to be solved.

As shown in fig. 2, an embodiment of the present disclosure provides an information transmission method, where the method is performed by a first network node, and includes:

step 201: and sending first auxiliary information to a second network node, wherein the first auxiliary information is used for indicating the first access layer capability of the first network node.

The first network node may comprise an access network device.

The first network node may be a network node that needs to establish a connection with the UE or needs to communicate with the UE.

The second network node may be at least one of: a network node that instructs the first network node to establish a connection with the UE or instructs the first network node to communicate with the UE;

a communication connection is currently established with the UE, indicating that the first network node establishes a connection with the UE, or indicating that the first network node communicates with the UE.

In one embodiment, the second network node is a core network device, and the first network node is a base station;

or alternatively, the process may be performed,

the second network node is a second base station, and the first network node is a first base station;

or alternatively, the process may be performed,

the second network node is a centralized unit CU of the base station and the first network node is a distributed unit DU of the base station.

In one possible implementation, the second network node is a core network device that sends a paging message of the UE to the base station, and the first network node is a current serving base station of the UE

For an NR system, when the NG interface is established or updated, the base station may notify the core network of the first access layer capability of the base station by carrying first auxiliary information through an NG establishment REQUEST (NG SETUP REQUEST) message and an access network configuration upgrade RAN CONFIGURATION UPDATE message.

In one possible implementation, the second network node (second base station) is a source base station of the UE, and the first network node (first base station) is a target base station for handover of the UE.

In one possible implementation, the second network node (second base station) is an anchor base station for the UE and the first network node (first base station) is a current serving base station for the UE.

For an NR system, when an interface between base stations is established or updated, the base station may notify the neighboring base station of the first access layer capability by carrying first assistance information through an XN SETUP REQUEST (XN SETUP REQUEST) message, an XN SETUP response (XN SETUP RESPONSE) message, an NG-RAN node configuration update (NG-RAN NODE CONFIGURATION UPDATE) message, or an NG-RAN node configuration update confirm (NODE CONFIGURATION UPDATE ACKNOWLEDGE) message.

In one possible implementation, the base station may employ a CU and DU separated architecture, where the CU is responsible for Radio resource control (Radio Resource Control, RRC)/service data adaptation protocol (Service Data Adaptation Protocol, SDAP)/packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer baseband protocol processing and provides an interface with devices such as a core network, a network manager, and the like, and the DU performs Radio link layer control protocol (Radio LinkControl, RLC)/medium access control (Media Access Control, MAC)/Physical layer (PHY) protocol and part of Radio frequency processing functions, and provides a forwarding interface with the Radio frequency unit, where the CU interacts signaling and user data with the DU through an F1 logical interface.

For an NR system, when a base station establishes or updates an F1 application protocol (F1 AP) interface under a CU and DU separation architecture, a DU of a gNB may carry first auxiliary information through an F1 SETUP REQUEST (F1 SETUP REQUEST) message and a gNB-DU configuration update (gNB-DU CONFIGURATION UPDATE) message, and notify a CU of the gNB of a first access layer capability of the DU of the gNB.

Here, the first access stratum capability may be a communication capability that the first network node is able to communicate at the access stratum.

In one possible implementation, the first access layer capability may include, but is not limited to, one of the following:

an access stratum protocol supported by the first network node;

a device supported by the first network node access layer;

the first network node accesses the resource types supported by the layer.

The first network node sends first assistance information to the second network node, which may determine a first access stratum capability of the first network node.

In one possible implementation, the second network node may determine services that the first network node can conduct, e.g., determine UEs that the first network node can access, based on the first access layer capability.

In this way, the first network node indicates the first access layer capability to the second network node through the first auxiliary information, so that the second network node can determine the first access layer capability of the first network node, the transparency of the first network node information is increased, invalid communication generated by the second network node which does not determine the first network node access layer capability is reduced, and the communication efficiency is improved.

In one embodiment, the first auxiliary information is carried in UE-related signaling or non-UE-related signaling;

the UE-associated signaling may be in-transit signaling for UE-related services. Including but not limited to signaling during at least one of:

signaling during UE mobility management procedures, handover, path change

Signaling in the paging procedure.

The non-UE-associated signaling may be signaling transmitted in a non-UE-related service, e.g., signaling transmitted over an NG interface between an NG-RAN and an AMF. Including but not limited to signaling during at least one of:

interface management flow;

and configuring a transfer flow.

In one embodiment, the first access layer capability is used for the second network node to determine whether to send a paging message of a user equipment to the first network node.

In one possible implementation, the first access layer capability may be used by the second network node to determine whether the UE can access the first network node, and the second network node may then determine whether to send a paging message for the UE to the first network node.

For example, the first access layer capability may indicate whether the first network receives support for the UE.

In one possible implementation, a paging message of the UE is sent to the first network node in response to determining that the UE is capable of accessing the first network node.

In one possible implementation, in response to determining that the UE is unable to access the first network node, a paging message for the UE is not sent to the first network node.

In one embodiment, the first access stratum capability of the first network node comprises at least one of:

whether the first network node supports enhanced capability curtailment eRedCAP User Equipment (UE);

whether the first network node supports eRedCAP UE of a first type;

whether the first network node supports a second class eRedCAP UE;

whether the first network node supports the eRedCap UE to adjust a peak rate;

whether the first network node allows the second class eRedCap UE to adjust peak rates.

The first access layer capability may indicate whether the first network receives support for the eRedCap UE. Here, the eRedCap UE may be an eRedCap UE specified in release 18 (R18).

In one possible implementation, the eRedCap UE includes at least: a first class of eRedCAP UE and a second class of eRedCAP UE.

The first class of eRedCap UEs may be UEs supporting bandwidth reduction scheme 3 (BW 3). I.e. the scheduling of the data channel by the first class of eRedCap UEs is reduced to a bandwidth of 5M, the scheduling of the control channel is maintained at 20M, the first class of eRedCap UEs simultaneously supports peak rate reduction, i.e. PR1 (peak rate reduction scheme 1) scheme, the first class of eRedCap UEs may be referred to as eRedCap UEs (Rel-18 eRedCap UE capable of BW3/pr3+pr1) supporting BW3/PR3 and PR1 by release 18.

The second class of eRedCap UEs may be 3GPP standard release 17 (R17) Redcap UEs that implement the peak rate reduction requirement of eRedCap for R18 by their own hardware. The second class of eRedCAP UEs may be referred to as release 18eRedCAP UEs (Rel-18eRedCap UE capable of 20MHz+PR1) supporting a 20MHz bandwidth and PR 1.

The second class of eRedCap UEs adjusts the peak rate, which may include increasing and decreasing the peak rate.

The second class of eRedCAP UE supports peak rate adjustment, namely the second class of eRedCAP UE adopts 5M bandwidth limitation when initially accessing, and can report larger bandwidth later (namely peak rate lifting is performed) and works at 20M. The base station may therefore hand off the second class of eRedCAP UEs with this capability to the base station supporting R17 Redcap. The base station supporting R17 Redcap here has a higher peak rate.

For example, the first access stratum capability may be used by the second network node to determine whether the first network supports access to the first class eRedCap UE, and the second network node may further determine whether to send a paging message of the UE to the first network node.

For example, the first access layer capability may indicate whether the first network receives the unredcap UE of the first type, and if so, the second network node sends a paging message of the unredcap UE of the first type to the first network node; otherwise, the second network node does not send the paging message of the first class eRedCap UE to the first network node.

The eRedCap UE adjusts the peak rate, which may include increasing and decreasing the peak rate. For example, the eRedCAP UE may employ a 5M bandwidth limit at initial access, and may subsequently report a larger bandwidth (i.e., peak rate up) operating at 20M. In one possible implementation, the first assistance information may indicate the first access layer capability with one or more bits.

In one possible implementation, different bits in the first assistance information correspond to different first access layer capabilities.

For example, the first assistance information may have 4 bits, wherein one bit is used to indicate whether the first network node supports enhanced capability curtailment eRedCap user equipment UE; another bit is used to indicate whether the first network node supports the second class of eRedCap UEs; a third bit for indicating whether the first network node allows the second class eRedCap UE to adjust a peak rate; the 4 th bit is used to indicate whether the first network node supports the eRedCap UE to adjust the peak rate.

In one embodiment, the first access layer capability is base station granularity;

or (b)

The first access stratum capability is cell-granularity.

Illustratively, the first access layer capability is a base station granularity, i.e., the first access layer capability may cover all cells associated with the base station. The first access layer capability may indicate whether the base station supports one of: eRedCAP UE; a first class of eRedCap UEs; the method comprises the steps of carrying out a first treatment on the surface of the A second class of eRedCAP UEs; the second class eRedCAP UE adjusts the peak rate; the eRedCap UE adjusts the peak rate.

Illustratively, the first access layer capability is a cell granularity, i.e., the first access layer capability may cover one or more cells associated with the base station. The first access layer capability may indicate whether one or more cells support one of: eRedCAP UE; a first class of eRedCap UEs; the method comprises the steps of carrying out a first treatment on the surface of the A second class of eRedCAP UEs; the second class eRedCAP UE adjusts the peak rate; the eRedCap UE adjusts the peak rate.

For example, the first access stratum capability is cell granularity, the second network node (e.g., core network) determines that at least one cell of the first network node (e.g., base station) supports the first type eRedCap UE based on the first access stratum capability, and then the second network node sends a paging message of the first type eRedCap UE to the first network node. The second network node (e.g., core network) determines that the first network node (e.g., base station) does not support the first class eRedCap UE by the cell based on the first access stratum capability, and the second network node does not send a paging message of the first class eRedCap UE to the first network node.

As shown in fig. 3, an embodiment of the present disclosure provides an information transmission method, where the method is performed by a first network node, and includes:

step 301: determining the first access stratum capability based on at least one of: SIB1; MIB.

The SIB1 and/or MIB may be a message broadcasted by the first network node on the air interface, the SIB1 and/or MIB may carry information indicating the first access capability, and the first network node may determine the first access layer capability based on the information indicating the first access capability carried by the SIB1 and/or MIB.

In one possible implementation, the information indicating the first access capability carried by SIB1 and/or MIB may be preset or specified by a communication protocol.

In one embodiment, the determining the first access stratum capability based on the SIB1 includes:

the first access layer capability is determined based on an indication bit in the SIB1 indicating the first access layer capability.

Illustratively, SIB1 and MIB have an identification therein that indicates whether a particular type of UE is allowed access;

illustratively, SIB1 has an identification therein that indicates whether a particular type of UE is allowed access;

the identification of whether the specific type of UE allows access adopts the same indication bit, for example, SIB1 has an identification of whether R18 Redcap type UE (including the first type eRedCap UE and the second type eRedCap UE) allows access;

or alternatively, the process may be performed,

the SIB1 includes a first indicator bit indicating whether the first type eRedCap UE allows access, and a second indicator bit indicating whether the second type eRedCap UE allows access, where the first indicator bit and the second indicator bit are different.

In one possible implementation, the types of UEs may be differentiated based on the number of antennas. The indication bits may be a plurality of bits, e.g. different bit positions are used for distinguishing between different antenna types 1rx,2 rx.

Illustratively, SIB1 has an indication bit therein that indicates whether or not the eRedCap UE is allowed to use peak rate adjustment (decrease or increase); further, SIB1 has an indication bit therein indicating whether Rel-18 eRedCap UE capable of 20MHz+PR1 is allowed to use peak rate adjustment (decrease or increase).

As shown in fig. 4, an embodiment of the present disclosure provides an information transmission method, where the method is performed by a first network node, and includes:

step 401: and sending second auxiliary information to the second network node, wherein the second auxiliary information is used for indicating the second access layer capability of the UE.

In one possible implementation, the second assistance information is used to indicate a second access stratum capability of the UE connected to the first network node. For example, the first network node may be a serving base station at which the UE is currently.

The second access layer capability may indicate a communication capability of the UE at the access layer.

The second access stratum capability is configured to indicate at least one of: the UE reduces eRedCAP User Equipment (UE) for enhancing the capability;

The UE is of a first type eRedCAP; the UE is a second class eRedCAP UE; the UE is the eRedCap UE supporting peak rate adjustment; the UE is of the second class of eRedCap UEs supporting peak rate adjustment.

The first network node sends the UE first network node to the second network node, which may make the second network node define the second access layer capability of the UE, e.g., the second network node may define the type of the UE.

In one possible implementation, the first network node (e.g., a base station) may send the second assistance information to the second network node (core network device) if the UE makes an initial connection or enters an RRC non-connected state, etc. In this way, the core network device may determine the type of UE that is accessed or the type of UE that enters the RRC non-connected state. Here the RRC non-connected joint includes at least one of: an RRC inactive state; and RRC idle state.

In one possible implementation, the first network node (e.g., the source base station of the UE) may send the second assistance information to the UE before the UE is handed over to the second network node (e.g., the target base station of the UE handover). As such, the second network node may determine the type of UE requesting handover to the second network node, and the second network node may determine whether to allow UE connection based on its own capabilities.

As shown in fig. 5, an embodiment of the present disclosure provides an information transmission method, where the method is performed by a first network node and includes:

step 501: and receiving second auxiliary information sent by the second network node, wherein the second auxiliary information is used for indicating the second access layer capability of the UE.

In one possible implementation, the second assistance information is used for the first network node to determine whether to allow the UE to establish a connection with the first network node. The UE establishes a connection with a first network node, comprising one of: the UE is switched to a first network node; the UE receives a message, such as a paging message, sent by the first network node.

The second access stratum capability may be used by the first network node to determine the communication capability of the UE at the access stratum.

In one possible implementation, the first network node determines whether to allow the UE to establish a connection with the first network node based on the first access layer capability and the second access layer capability.

In one possible implementation, the UE access stratum capability sent by the second network node (e.g., core network device) to the first network node (e.g., base station) may be sent by the serving base station of the UE to the second network node. Wherein the serving base station of the UE may be the first network node.

In this way, the first network node determines the second access layer capability of the UE through the second auxiliary information, so that the first network node can determine the second access layer capability of the UE, invalid communication generated by the first network node not determining the access layer capability of the UE is reduced, and communication efficiency is improved.

In one embodiment, the second assistance information is carried in UE-related signaling or non-UE-related signaling.

In one embodiment, the second access layer capability includes at least one of:

the UE reduces eRedCAP User Equipment (UE) for enhancing the capability;

the UE is of a first type eRedCAP;

the UE is a second class eRedCAP UE;

the UE is the eRedCap UE supporting peak rate adjustment;

the UE is of the second class of eRedCap UEs supporting peak rate adjustment.

The second access layer capability may be used to determine the type of UE.

In one possible implementation, the second access layer capability may be used to indicate the type of UE.

For example, the second access layer capability may indicate whether the UE is an eRedCap UE. Here, the eRedCap UE may be an eRedCap UE specified in release 18 (R18).

The second class of eRedCap UEs supports peak rate adjustment, i.e., the second class of eRedCap UEs uses 5M bandwidth limitation at the initial access, but may report a larger bandwidth later (i.e., peak rate up) and operate at 20M. The base station may therefore hand off the second class of eRedCAP UEs with this capability to the base station supporting R17 Redcap.

For example, the second access layer capability may be used by the first network node to determine whether the UE is an eRedCap UE of the first type, and if the UE is an eRedCap UE of the first type and the first network node supports the eRedCap UE of the first type, allow the UE to access; if the UE is a first class eRedCAP UE and the first network node does not support the first class eRedCAP UE, then the UE is not allowed access.

The eRedCap UE adjusts the peak rate, which may include increasing and decreasing the peak rate. For example, the eRedCAP UE may employ a 5M bandwidth limit at initial access, and may subsequently report a larger bandwidth (i.e., peak rate up) operating at 20M.

In one possible implementation, the second assistance information may indicate the second access layer capability with one or more bits.

In one possible implementation, different bits in the second assistance information correspond to different first access layer capabilities.

For example, the second assistance information may have 3 bits, wherein one bit is used to indicate whether the UE is an enhanced capability curtailed eRedCap user equipment UE; another bit is used to indicate whether the UE is an eRedCap UE of the first type; the third bit is used to indicate whether the UE is 1RX.

In one possible implementation, the second assistance information may be carried in a UE radio paging information message (UE radio paging information).

In one embodiment, the receiving the second auxiliary information sent by the second network node includes:

and receiving a paging message carrying the second auxiliary information.

Illustratively, the second network node (core network) carries second auxiliary information in the CN paging message, indicating that the type of UE associated with the paging message (e.g., the target UE of the paging message) is eRedCap UE.

Illustratively, the second network node (core network) carries second auxiliary information in the CN paging message, and indicates that the type of the UE (such as the target UE of the paging message) associated with the paging message is a first type eRedCAP, namely Rel-18 eRedCap:UE capable of BW3/PR3+PR1UE;

as an example: the anchor base station carries second auxiliary information in the RAN paging message, and indicates that the type of the UE (such as target UE of the paging message) associated with the paging message is a first type eRedCAP, namely Rel-18 eRedCap UE capable of 20MHz+PR1UE; alternatively, the second assistance information indicates that the UE associated with the paging message is a 1RX UE (i.e., the UE has 1 receive antenna).

As shown in fig. 6, an embodiment of the present disclosure provides an information transmission method, where the method is performed by a first network node, and includes:

step 601: determining whether to allow the UE to handover based at least on the first access stratum capability and/or a second access stratum capability of the UE.

The first network node may determine whether to allow the second access stratum capable UE to handover to the first network node based on its own first access stratum capability.

Illustratively, if the first network node does not support the first type eRedCAP UE and the UE making the handover to the first network node is the first type eRedCAP UE, then the UE is not allowed to handover to the first network node.

For example, during handover, the second auxiliary information may be carried in an inter-node message to notify the first network node (the target base station) (for example, notify the target base station UE to be an eRedCap UE, or whether the UE reports auxiliary information supporting peak rate reduction or improvement, or a combination of both); and the target base station performs admission judgment on the handover based on the second auxiliary information reported by the target base station (for example, when the base station is aware that the UE supports the higher peak rate, the base station can preferentially support the handover to the UE supporting the higher peak rate).

In a possible implementation manner, during the process of switching to the first network node, the second access layer capability of the UE is indicated by the second auxiliary information, or may be reported to the first network node by the UE.

In one embodiment, the sending the first assistance information to the second network node includes:

And in response to not allowing the UE to switch to the first network node, sending the first auxiliary information to the second network node.

If the UE fails to switch to the first network node, the first network node may send indication information indicating that the UE fails to switch to the second network node, where the first auxiliary information may be carried in a handover failure (handover) message indicating that the UE fails to switch, for the second network node to determine a first access stratum capability of the first network node.

In one possible implementation, the UE switches to the first network node, including one of:

the UE performs an Xn-based handover from the second network node to the first network node.

The UE performs NG-based handover from the second network node to the first network node.

For an exemplary NR system, during an NG-based HANDOVER, a first network node (base station) may inform a second network node (core network) of the first access layer capability of the first network node (base station) via a HANDOVER FAILURE message.

For an NR system, the first network node (target base station) may notify the first access layer capability of the first network node (base station) to the second network node (source base station) by a handover failure (handover) message, for example, during an Xn based handover procedure.

As shown in fig. 7, an embodiment of the present disclosure provides an information transmission method, where the method is performed by a first network node, and includes:

step 701: and sending handover failure reason information to the second network node in response to not allowing the UE to be handed over to the first network node.

In one possible implementation, the handover failure cause information may be carried in indication information indicating that the UE has failed handover.

For example, a handover failure (handover) message may be extended, a cause of failure (cause value) may be added, e.g. the type of UE is not supported or allowed, from which the second network node (core network or source base station) may obtain the first network node access layer capability. Among other types of UEs that are not supported or allowed may include, but are not limited to:

the first network node does not support or allow eRedCAP UE (i.e., R18 RedCAP);

the first network node does not support or allow the first type eRedCAP UE (Rel-18 eRedCap:UE capable of BW3/PR3+PR1;

step 801: and receiving first auxiliary information sent by a first network node, wherein the first auxiliary information is used for indicating the first access layer capability of the first network node.

a) The interacting node may be a base station and a base station;

b) The interactive node can be between the base station and the core network;

c) The interacting node may be between a gNB-CU and a gNB-DU.

2. Base station access layer (AS layer) capability (first access layer capability) is performed between nodes through non ue-associated signaling flow negotiations:
