[0002] The present application relates to a wireless communication network, and in particular to an information processing method, apparatus, device and storage medium. Background Art

[0003] In the new radio access technology NR (New Radio access) standard, the wireless capability information of the NR UE (User Equipment) itself needs to be provided to the next generation base station (Generation NodeB, gNB). Only after the base station knows the UE capabilities can it make correct scheduling for the UE. When the UE's wireless capability information includes a supported function, the base station can configure the resources related to the function for the UE based on the wireless capability information; if the UE's wireless capability information does not include a function that the UE can support, the base station cannot configure the function for the UE. At the same time, taking into account the UE attachment, TAU (Tracking Area Update) and capability changes, the base station forwards the UE's wireless capability information to the AMF (Access and Mobility Management Function), and the AMF stores the UE's wireless capability information for subsequent business use. After the NR protocol introduces NR low complexity UEs, the network side needs to know what functions the NR low complexity UE can support, whether it is resource allocation during service establishment, reconfiguration or handover, or scheduling during service maintenance. Under the current standard, the gNB base station cannot obtain the capabilities supported by the NR low complexity UE. Summary of the Invention

[0045] To make the purpose, technical solutions and advantages of this application more clear, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other in any way.

[0046] Figure 1 This is a flowchart of an information processing method provided in an embodiment of the present application. The embodiment of the present application is applicable to the case of uploading the NR low complexity UE capability information of the UE. The method can be performed by the information processing device in the embodiment of the present application. The device can be implemented by software and / or hardware and is generally integrated in the UE. The method in the embodiment of the present application specifically includes the following steps:

[0047] Step 101: Send radio capability information to the gNB; wherein the radio capability information includes UE capability information.

[0048] The wireless capability information may be the wireless capability information of the user equipment (EU), which may include information such as the number of antennas, bandwidth, working conditions, and processing delay. The gNB may be a 5G base station, which may configure resources to support the functions of the UE based on the wireless capability information uploaded by the UE.

[0049] Specifically, the UE can send its own wireless capabilities to the gNB to implement corresponding UE functions. It can be understood that the uploaded wireless capability information may include NR low complexity UE capability information. The UE can specifically be an NR low complexity UE and have corresponding NR low complexity UE capability information.

[0050] In one embodiment, the UE features include at least one of: reducing the number of UE RX / TX antennas, reducing UE bandwidth, half-duplex FDD, relaxing UE processing delay, and relaxing UE processing capability.

[0051] In one embodiment, the UE capability information is NR low complexity UE capability information, including at least one of the following:

[0052] NR low complexity UE category information, NR low complexity UE support indication information, NR low complexity UE reception capability information, NR low complexity UE upload capability information, UE transmission capability information, UE radio frequency capability information and UE measurement capability information.

[0053] Figure 2 This is a flow chart of an information processing method provided by an embodiment of the present invention. This embodiment of the present application is applicable to the case where the NR low complexity UE capability information of the UE is uploaded. Figure 2 The technical solution of the embodiment of the present application specifically includes the following steps:

[0054] Step 201: Send the wireless capability information to the gNB through the AMF.

[0055] In an embodiment of the present invention, when the UE uploads the wireless capability information, the wireless capability information of the UE can be sent to the gNB through the AMF, and the wireless capability information in the AMF can be the information stored after the UE uploads.

[0056] In one embodiment, sending the radio capability information to the gNB through the AMF includes:

[0057] Step 211: Establish a communication connection with the gNB so that the gNB sends initial UE information to the AMF, where the initial UE information includes at least one of service request information, attach request information, and TAU request information.

[0058] Step 212: The AMF sends an initial context establishment request to the gNB, wherein the UE radio capability information element of the initial context establishment request includes NR low complexity UE capability information.

[0059] Step 213: Obtain the radio resource control (RRC) reconfiguration information determined by the gNB according to the NR low complexity UE capability information, wherein the RRC reconfiguration information includes at least one of the following: measurement configuration information of the NR low complexity UE, radio resource configuration information of the NR low complexity UE, and mobility control information of the NR low complexity UE.

[0060] Specifically, Figure 3This is an example diagram of an information processing method provided by an embodiment of the present application, see Figure 3 In the embodiment of the present application, when the information indicating that the UE supports NR low complexity UE capabilities is transmitted through the AMF, communication between the UE and the gNB can be established through RRC MSG3, RRC MSG4, and RRC MSG5. Among them, the RRC MSG3 message can correspond to Msg3 of the random access process, and RRC MSG3 can specifically be an RRC connection request. The RRC MSG4 message can be Msg4 corresponding to the random access process. RRC MSG4 is for RRC connection establishment. The RRC MSG5 message does not carry any actual message and only serves as an RRC layer confirmation. RRC MSG5 is for RRC connection establishment completion. After the RRC connection is established, the gNB can send an initial UE message to the AMF. After obtaining the initial UE message, the AMF sends the initial context establishment request to the gNB in ​​the UE radio capability information element (UE RadioCapability) containing NR low complexity UE capability information. Furthermore, after obtaining the NR low complexity UE capability information of the UE, the gNB can send an RRC reconfiguration to the UE, and specifically reconfigure the NR low complexity UE of the UE, which may include the measurement configuration of the NR low complexity UE, the radio resource configuration of the NR low complexity UE and the mobility control of the NR low complexity UE.

[0061] In another embodiment, the gNB may proactively query the NR low complexity UE capability information supported by the UE and send the radio capability information to the gNB via the AMF, including:

[0062] Step 221: Establish a communication connection with the gNB so that the gNB sends initial UE information to the AMF, where the initial UE information includes at least one of service request information, attach request information, and TAU request information.

[0063] Step 222: The AMF sends an initial context establishment request to the gNB, wherein the UE radio capability information element of the initial context establishment request does not include NR low complexity UE capability information;

[0064] Step 223: Receive the UE capability query information sent by the gNB, and send radio capability information including NR low complexity UE capability information to the gNB; so that the gNB sends a UE capability information indication to the AMF according to the radio capability information, wherein the UE radio capability information element in the UE capability information indication includes NR low complexity UE capability information.

[0065] Specifically, Figure 4 This is an example diagram of an information processing method provided by an embodiment of the present application, see Figure 4 In the embodiment of the present application, when the UE changes its capability or mobility triggers a Tracking Area Update (TAU) or an attachment phase, and when the AMF fails to transmit the information during service establishment, the gNB needs to actively query the UE's support for NR low complexity UE capability information, thereby implementing the upload process of the NR low complexity UE capability information. First, the communication connection between the UE and the gNB can be established through RRC MSG3, RRC MSG4, and RRC MSG5. The RRC MSG3 message can correspond to the Msg3 of the random access process. The RRC MSG3 can specifically be an RRC connection request. The RRC MSG4 message can be the Msg4 corresponding to the random access process. The RRC MSG4 is the RRC connection establishment. The RRC MSG5 message does not carry any actual message and only serves as the RRC layer confirmation function. MSG5 indicates that the RRC connection establishment is completed. After the RRC connection is established, the gNB may send an initial UE message to the AMF. The initial UE message may include information such as service request, attach request, and TAU request. After receiving the initial UE message, the AMF may send an initial context establishment request to the gNB. At this time, the AMF does not store the UE's NR low complexity capability information, and the initial context establishment request may not include the UE radio capability information. After receiving the initial context establishment request, the gNB queries the UE capabilities. The UE may send UE capability information including NR low complexity UE capability information to the gNB according to the query request, and the gNB may then send the UE's NR low complexity UE capability information to the AMF through the UE capability information indication.

[0066] Figure 5 This is a flowchart of another information processing method provided by an embodiment of the present application. The embodiment of the present application is applicable to the case of uploading the NR low complexity UE capability information of the UE. The method can be performed by the information processing device in the embodiment of the present application. The device can be implemented by software and / or hardware. The method of the embodiment of the present application specifically includes the following steps:

[0067] Step 301: When sending a random access message 1, the radio capability information is sent to the gNB via uplink RRC information; wherein the random access message 1 is used to configure dedicated resources including a physical uplink shared channel in idle mode.

[0068] Specifically, Figure 6 This is an example diagram of an information processing method provided by an embodiment of the present application, see Figure 6When sending a random access message 1 (Msg1), the UE can add the NR low complexity UE capability information to the random access message and send it, wherein the random access message 1 can be the Msg1 containing the random access preamble (Preamble) and the physical uplink shared channel (PUSCH) in the two-step physical random access channel PRACH (two step prach) resource configuration process, and the Msg1 containing the physical uplink shared channel (PUSCH) for pre-configured dedicated resources in idle mode. In the embodiment of the present application, the random access message 1 can specifically carry the NR low complexity UE capability information through the uplink RRC message or the media access control channel element (MACCE) in the physical uplink shared channel, thereby realizing explicit reporting of the UE wireless capability information.

[0069] In one embodiment, sending the radio capability information to the gNB includes:

[0070] Step 311. Obtain the system information block SIB information sent by the gNB, wherein the SIB information includes the PRACH resource configuration information corresponding to the NR low complexity UE, and the PRACH resource configuration information corresponding to the NR low complexity UE includes the uplink bandwidth part BWP common parameters and the PRACH resource configuration information dedicated to sending the NR low complexity UE, or the PRACH resource configuration information corresponding to the NR low complexity UE includes the uplink BWP configuration information dedicated to sending the NR low complexity UE configuration and the PRACH resource configuration information corresponding to the BWP.

[0071] Step 312: Send a random access message 1 to the gNB, wherein the random access message 1 indicates the radio capability information using a random access preamble that is only used for NR low complexity UEs.

[0072] Specifically, Figure 7 This is an example diagram of an information processing method provided by an embodiment of the present application, see Figure 7 The UE can include the NR low complexity UE capability information in the random access message 1 and send it to the gNB. The SIB message can distinguish the PRACH resources configured for NR and NR low complexity UEs, and the NR low complexity UE capability information included can be implicitly determined through the SIB message. The UE can implicitly report the UE radio capability information in the random access message 1 sent only for NR low complexity UE during the random access initiation process, which may include the NR low complexity UE capability information.

[0073] Furthermore, there is at least one set of random access preamble codes used only for NR low-complexity UEs, and each of the random access preamble codes corresponds to a CORESET, wherein the CORESET is used to determine the possible location of the downlink control channel, and the random access preamble code is sent on the PRACH resource configured for the NR low-complexity UE to indicate the wireless capability information.

[0074] Specifically, a random access preamble independent of NR is configured for the NR low complexity UE to implicitly indicate the information of the NR low complexity UE capability, wherein the access preamble of the NR low complexity UE independent of the NR random access preamble can be multiple sets, each set of preambles can correspond to a CORESET, and can be represented by the PRACH resources configured only for sending the NR low complexity UE in the common parameters of the uplink BWP (BWP-UplinkCommon). The UE uses the method of sending the preamble in any set of NR low complexity UE preambles to indicate that the UE is a NR low complexity UE.

[0075] In one implementation, the UE may use an RRC message to report NR low complexity UE capability information when sending random access message 1 (MSG1), and send the radio capability information to the gNB, including:

[0076] Step 321. Obtain the SIB information sent by the gNB, wherein the SIB information includes the PRACH resource configuration information corresponding to the NR low complexity UE, and the PRACH resource configuration information corresponding to the NR low complexity UE includes the uplink BWP common parameters and the PRACH resource configuration information dedicated to sending the NR low complexity UE, or the PRACH resource configuration information corresponding to the NR low complexity UE includes the uplink BWP configuration information dedicated to sending the NR low complexity UE configuration and the PRACH resource configuration information corresponding to the BWP.

[0077] Step 322: Send a random access message 3 to the gNB, where the random access message 3 includes wireless capability information.

[0078] Furthermore, the radio capability information reflects the NR low complexity UE capability information in at least one of the following ways:

[0079] The NR low complexity UE capability information is explicitly included in the random access message 3, and is reflected in at least one of the following ways:

[0080] Utilize the reserved bit in the RRC setup request, resume request, and / or re-establishment request to indicate NR low complexity UE capability information;

[0081] Utilize the reserved bits in the NR low complexity UE-specific RRC establishment request, recovery request, and / or re-establishment request to indicate NR low complexity UE capability information;

[0082] The wireless capability information reflected in the random access message 3 may be reflected by indicating the NR low complexity UE capability information through MAC CE, and the NR low complexity UE capability information indicated by MAC CE is reflected in at least one of the following ways:

[0083] Utilizing a reserved bit in a reserved / logical channel identifier (R / LCID) MAC subheader to indicate the wireless capability information;

[0084] The wireless capability information is indicated by using a reserved value of LCID in the MAC subheader.

[0085] Furthermore, based on the above-mentioned embodiment of the application, the wireless capability information is indicated by using the reserved value of the LCID in the MAC subheader in the random access message 3, including:

[0086] A dedicated LCID value is defined for NR low complexity UE, which indicates both random access message 3 related information and radio capability information.

[0087] In the embodiment of the present invention, see Figure 8 , the NR low complexity UE capability information of the UE can be sent through random access message 3. Based on the use of SIB messages to distinguish the PRACH resources configured for NR and NR low complexity UE, the UE will initiate a random access process. The UE sends random access message 1 (MSG1) to the gNB and receives random access message 2 (MSG2) sent by the gNB. When the UE sends random access message 3 (MSG3) to the gNB, it can upload the UE wireless capability information in random access message 3, which can specifically be NR low complexity UE capability information. It can be understood that the method of sending NR low complexity UE capability information through random access message 3 can include explicit and implicit sending, among which explicit sending includes at least one of the following methods:

[0088] In the RRC establishment request, recovery request, and / or re-establishment request information, the UE uses a reserved bit in the information to distinguish NR UE capability information from NR low complexity UE capability information. That is, the gNB determines whether it is an NR low complexity UE based on the value of the reserved bit. For example, in the RRC establishment request, when the reserved bit in the information is defined as 1, it indicates the capability information of NR low complexity UE.

[0089] Based on the RRC establishment request, recovery request and / or re-establishment request of the NR UE, a new RRC establishment request, recovery request and / or re-establishment request is added that is only used for the NR low complexity UE, and the RRC establishment request, recovery request and / or re-establishment request dedicated to the NR low complexity UE carries the NR low complexity UE capability information; for example, relative to the RRC establishment request of the NR UE, on its basis, its one reserved bit is extended to nine reserved bits, and the RRC establishment request is defined as an RRC establishment request dedicated to the NR low complexity UE, and then one bit of the nine reserved bits is defined as 1 to indicate the capability information of the NR low complexity UE.

[0090] For the R / LCID MAC subheader accompanying the random access message 3, see Figure 9 , any one of its two reserved bits can be used to distinguish NR UE capability information from NR low complexity UE capability information. That is, the gNB determines whether it is NR low complexity UE capability information based on the reserved bit value in the R / LCID MAC subheader. For example, in the R / LCID MAC subheader, when the second reserved bit is defined as 1, it indicates NR low complexity UE capability information. For example, the LCID value in the uplink shared channel can be shown in the following table:

[0091] Table 1 LCID values ​​for uplink shared channels

[0092]

[0093] Implicit transmission is achieved by defining a dedicated LCID value for Random Access Message 3 for NR Low Complexity UEs using the reserved LCID value in the MAC subheader transmitted on the uplink shared channel. Based on the received dedicated LCID value, the gNB determines that the UE is an NR Low Complexity UE. For example, considering that the LCID range is 0 to 63 and the reserved LCID range is 33 to 51, the LCID value Y in the MAC CE is selected to indicate that the NR Low Complexity UE capability information and Random Access Message 3 are transmitted on the 48-bit Common Control Channel (CCCH), and alternatively, the LCID value Z in the MAC CE is selected to indicate that the NR Low Complexity UE capability information and Random Access Message 3 are transmitted on the 64-bit CCCH, where Y and Z are integers between 33 and 51. Other values ​​in the reserved value range can also be used. This example uses NR Low Complexity UE as an example, but the concept is also applicable to high-performance and capability-constrained UEs.

[0094] In one embodiment, the NR low complexity UE capability information is carried by the resource corresponding to the confirmation / negative confirmation (ACK / NACK) feedback information corresponding to the random access message 4, and the radio capability information is sent to the gNB.

[0095] Specifically, carrying the NR low complexity UE capability information through the resources corresponding to the ACK / NACK feedback information corresponding to the random access message 4 can be implemented by the following steps:

[0096] Step 331: The resources corresponding to the ACK / NACK feedback information corresponding to the random access message 4 are sent to the gNB, carrying the NR low complexity UE capability information, where the feedback information of the random access message 4 includes the wireless capability information.

[0097] Furthermore, carrying the wireless capability information through resources corresponding to the ACK / NACK feedback information corresponding to the random access message 4 specifically includes at least one of the following:

[0098] Indicating the wireless capability information using a resource index corresponding to the ACK / NACK feedback information;

[0099] Transmitting the ACK / NACK feedback information and the information indicating the radio capability to the gNB via a physical uplink control channel;

[0100] The wireless capability information is indicated by using a scrambling code or a reference signal sequence corresponding to the ACK / NACK feedback information.

[0101] Specifically, Figure 10 This is an example diagram of an information processing method provided by an embodiment of the present application, see Figure 10 , the UE may include the NR low complexity UE capability information in the ACK / NACK feedback information of random access message 4 and send it to the gNB. It is understood that there are three ways to send the NR low complexity UE capability information through the feedback information of random access message 4: method 1 is to use the resource index corresponding to the ACK / NACK feedback information to indicate the radio capability information; method 2 is to transmit the ACK / NACK feedback information and the information indicating the radio capability to the gNB via a physical uplink control channel; method 3 is to use the scrambling code or reference signal sequence corresponding to the ACK / NACK feedback information to indicate the radio capability information.

[0102] Figure 11This is a flowchart of an information processing method provided by an embodiment of the present application. The embodiment of the present application is applicable to the case of uploading the NR low complexity UE capability information of the UE. The method can be executed by the information processing device in the embodiment of the present application. The device can be implemented by software and / or hardware and is generally integrated in the UE. Figure 11 The method of the embodiment of the present application specifically includes the following steps:

[0103] Step 401: The source gNB forwards the radio capability information to the target gNB.

[0104] In one embodiment, forwarding the radio capability information to the target gNB by the source gNB includes:

[0105] Step 411: Send a handover request message to the target gNB through the source gNB, wherein the source-to-target transparent container information element of the handover request message contains NR low complexity UE capability information.

[0106] Step 412: After obtaining the resource admission qualification of the target gNB and allocating the resources required based on the NR low complexity UE capabilities in the target gNB, the source gNB receives the handover request confirmation information sent by the target gNB.

[0107] For details, see Figure 12 Taking the transmission of a UE's NR Low Complexity UE capability information during an inter-gNB handover over the Xn interface as an example, the source gNB may store the NR Low Complexity UE capability information reported by the UE. When the source gNB sends a Handover Request message (HANDOVERREQUEST) to the target gNB, the source gNB may include the UE's NR Low Complexity UE capability information in the Handover Request message. Specifically, the information may be added to the Source to Target Transparent Container information element. Furthermore, after receiving the Handover Request, the target gNB may send a Handover Request Acknowledge message (HANDOVERREQUESTACKNOWLEDGE) to the source gNB. The Handover Request Acknowledgement may include the resources allocated by the target gNB based on the UE's NR Low Complexity UE capability information.

[0108] In one embodiment, forwarding the radio capability information to the target gNB by the source gNB includes:

[0109] Step 421: The source gNB sends a handover request message to the AMF, which forwards the handover request message to the target gNB. The source-to-target transparent container information element of the handover request message and the handover request message contains NR low complexity UE capability information.

[0110] Step 422: After obtaining the resource admission qualification of the target gNB and allocating the resources required based on the NR low complexity UE capabilities in the target gNB, the AMF forwards the handover request confirmation information sent by the target gNB to the source gNB using the handover command.

[0111] See also Figure 13 In the embodiment of the present application, taking the transmission of NR low complexity UE capability information supported by the UE during handover based on the NG interface as an example, during inter-gNB handover based on the NG interface, the NR low complexity UE capability information of the UE may be sent to the target gNB through the source gNB and the AMF. The source gNB may include the obtained NR low complexity UE capability information of the UE in the handover request information (HANDOVER REQURED), which may specifically be a source-to-target transparent container (Source to TransparentContainer) information element. The AMF may send a handover request message (HANDOVER REQUEST) to the target gNB, wherein the source-to-target container (Source to Transparent Container) information element of the handover request message includes the NR low complexity UE capability information. The target gNB may determine the resource admission qualification of the UE in the target gNB based on the NR low complexity UE capability information. The target gNB may send a handover request acknowledgment message (HANDOVER REQUSET ACKNOWLEDGE) to the AMF, wherein the target-to-source container may include resources allocated according to the NR low complexity capability information. The AMF may then transmit the handover command information (HANDOVER The Target to Source TransparentContainer (TSC) information element is sent to the source gNB, where the target gNB has allocated resources required based on the NR Low Complexity UE capabilities. In one embodiment, the number of AMFs is at least one. During NG-based handover, the NR Low Complexity UE capability information of the UE can be delivered to the target gNB via different AMFs.

[0112] For example, Figure 14 This is an example diagram of an information processing method provided by an embodiment of the present application, see Figure 14Taking the example of handover based on the NG interface and transmitting the UE's support for NR Low Complexity UE capability information to different AMFs, the source gNB can first send a Handover Request message (HANDOVER REQUIRED) to the source AMF, where the Source to Target Transparent Container information element contains the NR Low Complexity UE capability information. The source AMF sends a Handover Request message (HANDOVER REQUEST) to the target AMF, where the Source to Target Transparent Container information element contains the NR Low Complexity UE capability information. The target AMF sends a Handover Request message (HANDOVER REQUEST) to the target gNB, where the Source to Target Transparent Container information element contains the NR Low Complexity UE capability information. After obtaining the target gNB resource admission qualification for the NR Low Complexity UE, the target gNB sends a Handover Request Acknowledge message (HANDOVERREQUEST ACKNOWLEDGE) to the target AMF, where the Target to Source Transparent Container information element contains the target gNB's allocation of resources required for the NR Low Complexity UE's capabilities. The target AMF sends a Handover Request Acknowledge message (HANDOVERREQUEST ACKNOWLEDGE) to the source AMF, where the Target to Source Transparent Container information element contains the target gNB's allocation of resources required for the NR Low Complexity UE's capabilities. The source AMF sends a Handover Command message (HANDOVER COMMAND) to the source gNB, where the Target to Source Transparent Container information element contains the target gNB's allocation of resources required for the NR Low Complexity UE's capabilities. The technical solution of the embodiment of the present application sends radio capability information including NR low complexity UE capability information to the gNB, so that the gNB obtains the capabilities supported by the UE, allocates relevant resources to the UE, and implements the corresponding functions of the UE, thereby ensuring the availability of UE services and improving the user experience.
