detailed description

In order to make the objectives, technical solutions, and advantages of the disclosure more clear, the disclosure will be described in detail below with reference to the drawings and specific embodiments.

The background art related to the present disclosure is described below.

(1) Random access process

After the cell search process, the UE has achieved downlink synchronization with the cell, so the UE can receive downlink data. However, the UE can perform uplink transmission only when it obtains uplink synchronization with the cell. The UE establishes a connection with the cell and obtains uplink synchronization through a random access procedure (Random Access Procedure).

There are 2 different ways of the random access process:

1. Based on Contention, Random Access (CBRA), as shown in Figure 1, the main process is:

Message 1 (Msg1): the UE selects a random access preamble and a Physical Random Access Channel (PRACH) resource and uses the PRACH resource to send the selected random access preamble to the base station;

Message 2 (Msg2): Random Access Response (RAR) message, random access response monitoring, UE monitors the physical downlink control channel (Physical Downlink Control CHannel, PDCCH) in the window to receive the corresponding random access Reply;

Message three (Msg3): The UE sends uplink transmission on the uplink grant (UL grant) designated by Msg2. There may be different signaling contents for different scenarios, for example, radio resource control (RRC) re-establishment request / RRC establishment request / system information request, etc .;

Message four (Msg4): The contention resolution message, the UE can determine whether the random access is successful according to Msg4.

2. Based on non-competition (Contention-Free Random Access, CFRA), as shown in Figure 2, the main process is:

Msg0: dedicated preamble and dedicated resource allocation for random access (RRC reconfiguration message);

Msg1: The UE selects a suitable random access preamble according to its own measurement results (Synchronization Signal Block (SSB) / Channel State Information Reference Signal (Channel-State Information Reference Signal (CSI-RS) Index, etc.) and selection criteria. And PRACH resources and use the PRACH resources to send the selected random access preamble to the base station;

Msg2: Random access response monitoring, the UE monitors the PDCCH in the window to receive the corresponding random access response.

(2) Reference signal for NR measurement

Reference signals for NR measurement are divided into SSB and CSI-RS.

(3) Dedicated / public random access

The handover command includes at least the cell identity of the target cell and the RACH configuration related to the beam configuration.

The UE selects a suite among all beams in the target cell.

If CFBA resources are not provided for the beam selected by the UE, the UE performs CBRA on the selected beam.

The public RACH configuration of the Beam of the target cell is only associated with the SSB. The network can have dedicated RACH configurations (SSB / CSI-RS ID, dedicated RACH resources, dedicated preamble, etc.) related to SSB or CSI-RS in a cell. In order for the target cell to access the UE, the RRC reconfiguration command may include one of the following RACH configurations:

Public RACH configuration;

Public RACH configuration and dedicated RACH configuration associated with SSB;

Public RACH configuration and dedicated RACH configuration associated with CSI-RS;

If the measurement result obtained by performing measurement on the NR-SS or CSI-RS is higher than the threshold, the priority of the dedicated RACH resource associated with it is higher. That is, if the measurement result of the SSB / CSI-RS corresponding to the configured dedicated RACH resource exceeds the set threshold, the CFRA will be directly used for the dedicated resource, and the UE will not use the public RACH resource for CBRA; the NR-SS / CSI-RS threshold, Related resources and related preambles can be configured in the handover command.

(4) Dual connectivity architecture

In a dual connectivity architecture, the UE may have one MN and one or more SNs. Both MN and SN can be LTE / e-LTE / NR nodes. When the network decides to add / replace an SN to the UE or modify the SCG radio resource configuration for the SN, if it needs to use the resources of the SN, it needs to initiate a random access procedure for the SN.

The following takes the SN adding process as an example:

Steps 1-2: The MN sends an SN addition request to the SN and a related reply message;

Steps 3 to 5: The MN sends an RRC reconfiguration message to the UE, a related reply message from the UE to the MN, and a related reconfiguration complete message from the MN to the SN. The RRC reconfiguration message carries the SN related configuration parameters. If the SCG radio resource configuration is included, step 6 is performed.

Step 6: If a bearer that requires the use of SCG radio resources is configured, the UE needs to synchronize with the primary and secondary serving cells (PSCells) of the SN, that is, initiate random access to the network.

Steps 7 to 12: State transfer, data forwarding, and path conversion processes between the MN and the SN and core network nodes.

In step 6, the UE initiates random access to the SN, and may initiate non-competitive random access based on the dedicated RACH resources associated with beam and preamble (possibly associated with SSB or CSI-RS) allocated in the RRC reconfiguration message in step 3. Or use the public RACH resource given in the RRC reconfiguration message and select an available preamble to initiate contention-based random access.

The content in step 6 can also be used:

Replacement of SN, or

SN internally adjusts SCG radio resources (SN modification).

These two processes may be initiated by the MN or by the SN.

(5) Uplink (UL) and Supplementary Uplink (SUL)

Due to the high frequency used by the NR system, the coverage may be reduced. To supplement this coverage, the network can configure two sets of parameters, UL and SUL, for the uplink of the UE. For frequency division duplex (FDD) or time division duplex (TDD), an additional SUL can be configured for the UE to ensure coverage. The coverage of SUL is greater than the coverage of UL.

When the downlink measurement quality of the UE on the UL carrier is lower than the network broadcast threshold, the SUL carrier and related configurations are used for random access. Once started, all uplink transmissions of this random access can only be sent on the selected SUL frequency.

(6) Bandwidth Part (BWP)

Under the adaptive bandwidth (Bandwidth Adaptation, BA) technology, the receiving and transmitting bandwidth of the UE does not need to be as large as the bandwidth of the cell, and is also set to be configurable. A subset of all bandwidth in a cell is called BWP.

The BWP of the UE's initial access to the cell is initial BWP, which is common to both idle and connected UEs. Initial BWP generally has a narrow bandwidth. After the UE enters the connected state, the network can allocate other uplink and downlink BWPs for the UE, and only the connected UE is available. The BWP that initiates random access after the UE receives the synchronous reconfiguration message is the uplink firstActiveBWP.

The present disclosure provides a method for reporting information, a method for acquiring information, a terminal, and a network device in response to a problem that the content and reporting of random access success and / or failure of the SN cannot be guaranteed in the related art, and network communication reliability cannot be guaranteed.

As shown in FIG. 4, an information reporting method according to an embodiment of the present disclosure, which is applied to a terminal, includes:

Step 41: During the random access process between the terminal and the secondary node, record reporting information on the target access status of the secondary node;

It should be noted that the target access status is successful access or failed access.

Step 42: Send the reported information to a network device.

It should be noted that the reported information includes at least one of beam related information, resource related information, cell related information, terminal location information, and time related information.

The specific content contained in the reported information is described below.

I. Beam related information

It should be noted that the beam related information includes at least one of the following information:

A11. First beam information;

It should be noted that when the target access status is access failure, the first beam information is beam information of a terminal failure. The beam information mentioned here is specifically the beam identification information, for example, the beam's index.

A12. Measurement information of a beam of the first cell;

It should be noted that the first cell includes a cell where the terminal under the secondary node initiates random access; further, the first cell further includes: a neighbor of a cell where the terminal under the secondary node initiates random access Plot.

It should be noted that the NR system introduces beam-level information, and uses SSB and CSI-RS as measurement reference symbols.

During the SN addition process, the SN change process, or the SN modification process, the terminal may initiate an access request to the SN or respond to a network reconfiguration request through random access. If an access failure occurs, the terminal can record the following:

A1. Beam information when the terminal fails, and measurement results for the beam;

A2. The terminal's failed SN target cell measurement results recorded before the failure, including RSRP and RSRQ (RSRQ value is related to type), and related beam-level measurement results, including SSB and CSI-RS-based measurement results;

A3. The measurement results of each serving cell before the terminal fails, including RSRP and RSRQ (RSRQ value is related to type), and possible beam level measurement results, including SSB and CSI-RS-based measurement results;

A4. The measured results of each neighboring cell, including each access network system (RAT);

Further, after the related network side receives the beam-level measurement result related to the access failure, it can be used to adjust configuration parameters related to the beam, for example, preamble and RACH resource configuration associated with the beam. ; Or report to the data collection node (TCE) for operators to perform big data statistics and other purposes.

Second, resource related information

It should be noted that the resource-related information includes at least one of the following information:

B11. Preamble and random access channel RACH resource information used by the terminal;

B12. Number of preamble transmissions;

B13. Information indicating whether the maximum transmission power of the preamble is reached;

B14. Information indicating whether competition occurs.

It should be noted that after receiving the measurement result record, the relevant network side can be used to adjust configuration parameters related to RACH, such as preamble allocation and RACH resource configuration.

The network can configure random access parameters for the terminal in one of the following ways:

B1. Public RACH configuration;

B2. Public RACH configuration and dedicated RACH configuration associated with SSB;

B3. Public RACH configuration and dedicated RACH configuration associated with CSI-RS;

If the network is configured with public and private RACH configuration information for the terminal, the terminal needs to determine whether to use the public RACH for CBRA or to associate with a SSB / CSI-RS based on its own beam-level measurement results and the reference threshold of the network configuration. The dedicated RACH is configured for CFRA, so the UE needs to report the actual RACH related parameters, including CFRA / CBRA, the preamble used and the number of transmissions, whether it has reached the maximum transmission power, and the actual RACH resource information used.

After the relevant network side receives the preamble and RACH resource information related to the access failure or access success, it can be used to improve the RACH resource allocation scheme. For example, changing the reference threshold for the dedicated RACH resource configured for the terminal. Value, etc .; or reported to TCE for operators to perform big data statistics and other purposes.

It should also be noted that when the target access status is access failure, the resource related information includes at least one of the following information:

B21: Carrier information where an access failure occurs;

It should be noted that the carrier information may be that the terminal uses a UL carrier or the terminal uses a SUL carrier. Specifically, the network notifies the terminal of the synchronous reconfiguration message used for random access, and it notifies that the terminal is required to use UL or SUL after accessing. If the terminal does not record and report after the access failure occurs, the network side may send other configuration information to the UE and delete the configuration information that caused the failure. Therefore, the terminal records the carrier information when an access failure occurs, which is helpful for subsequent network side to determine the cause of failure and adjust parameters after receiving.

B22. Random access priority related information used by the terminal;

Specifically, the random access priority related information includes: power boost step size information and / or back-off indication information.

The power boost step size information (powerRampingStepHighPriority) indicates that there is a power boost step for sending a preamble for random access of different priorities; the scaling factor information (scalingFactorBI) indicates that there is a backoff indication for random access of different priorities The specific content of the fallback indication is the scaling factor used for the fallback.

B23. The first activated bandwidth segment where an access failure occurs.

It should be noted that the synchronous reconfiguration message used by the network to notify the terminal for random access will notify the first active BWP (firstActiveBWP) used after the UE is requested to access, and the BWP may be the same as the initial BWP does not overlap other BWP. If the terminal fails to record and report after the access failure occurs, the network side may send other configuration information to the terminal and delete the configuration information that caused the failure. Therefore, the terminal records the first ActiveBWP when an access failure occurs, which is helpful for subsequent network side to determine the cause of the failure and adjust parameters after receiving.

After the relevant network side receives the carrier / BWP record related to the access failure, it can be used to improve the configuration parameters of the synchronous reconfiguration, for example, it is reported to the data collection node (TCE) and used by the operator for big data statistics and other purposes.

In addition to the above carrier / BWP information, if the terminal records and reports are not performed immediately after the access failure, more parameters may need to be recorded by the terminal itself and reported to the network in the subsequent process. For example, the random access priority related information used in random access, etc., all help the network to determine the cause of the access failure and guide subsequent configuration or adjustment of resource allocation.

Third, community related information

It should be noted that when the target access status is access failure, the cell related information includes at least one of the following information:

C1. Identification information of a cell where an access failure occurs;

C2. Registered Public Land Mobile Network (PLMN) with access failure;

C3. Measurement results of the serving cell before the access failure;

C4. Measurement results of other cells except the serving cell before the access failure.

Fourth, the location information of the terminal

It should be noted that the location information of the terminal refers to the geographic location information of the terminal, for example, ObservedTimeDifferenceOfOrroa (OTDOA) positioning results, horizontal and vertical positioning results, or Global Navigation Navigation System (Global Navigation) (Satellite System, GNSS) positioning results, etc., used to adjust the position-related parameters of nodes that have failed, such as the number of SSBs, antenna position / antenna tilt, transmit power, or used for data collection nodes / operator big data statistics needs .

Five, time-related information

It should be noted that the time-related information is mainly recorded when the target access status is access failure. The time-related information includes the time interval between the time when the access failure occurs and the time when the failure is reported. The time-related information is mainly used to assist the receiving node to find the failed node and judge the validity of the data.

It should further be noted that one way of sending the reported information is:

It should be noted that because the amount of information recorded by the terminal is huge, SCGFailureReport only needs to report information that helps the network side to quickly establish a new SN connection to the terminal after the SN connection fails, so the SN access fails or the access is successfully reported The information can be saved in the terminal, and the available indication information is reported to the network side after saving. As the current record is for the SN, the terminal still maintains the connection in the MN, so it can directly carry the available indication in all the next available uplink RRC messages of the MN, or in any process of changing cells / connection establishment or restoration / reconstruction, etc. Carry the available indication, or, for the case of successful access, send the available indication to the SN. The available indication information may occupy only 1 bit, and is used to notify the network side that the terminal stores the reporting information of the related access failure or successful access, or distinguishes between the reporting information of successful access and the reporting information of access failure, respectively. When the network side needs the reporting information of the access failure or successful access, it sends a downlink signaling request to the UE to report. The UE may carry all the related record content (that is, reporting information) of access failure or access success in the uplink information of the lower priority.

If after the terminal reports the available indication information, the network side does not immediately request the UE to report, the UE keeps a record of the access failure / success for a period of time, which can be controlled by a timer. For example, if the network has not requested a report for more than 3 hours, the terminal itself deletes the saved report information of the access failure or successful access.

It further needs to be explained that when the target access status is access failure, another way of sending information is:

It should be noted that in the case of an SCG failure, the protocol has introduced SCGFailureReport signaling, which is used by the UE to notify the network of the failed link information through the link that has not failed, so that the network quickly configures a new link for the UE. Data transmission continues. Therefore, one possible reporting method is: the reporting information for the access failure of the SN recorded by the UE can be notified to the MN network side or other SN network sides that have not failed through the SCGFailureReport signaling.

It should be noted here that when the terminal successfully accesses, it indicates that it establishes a connection with the secondary node. At this time, the report information can be sent directly to the secondary node or to the primary node, that is, the above network device refers to the secondary node. And / or the primary node; and when the terminal fails to access, it indicates that it has not established a connection with the secondary node. At this time, the terminal can only communicate with the primary node. Therefore, in this case, the above network equipment refers to The master node.

Since the reported information is a record of the terminal's access failure or successful access to the access node B, the node A on the network side receiving the record of the terminal may not be the node B where the access failure or successful access occurs. To deal with this situation, there are two follow-up methods:

Method 1: If the terminal record information set for access failure or successful access cannot be used for base station side configuration / resource adjustment, node A on the receiving network side does not need to parse the terminal record content, and the receiving node A directly reports to TCE , Used by operators for big data statistics and operator decision making;

Method 2: If the terminal record information set for access failure or successful access can be used by Node B where the terminal fails, for example, it is used to adjust the configuration parameters at the base station side, adjust resource scheduling, adjust beam information, etc. Then, Node A may preliminarily analyze the node B on the network side where the terminal indicates a problem in the reported information, and send the recorded content to Node B where the UE has experienced an access failure or successful access. Node B can use the recorded content to perform base station related optimization and / or report to TCE for operators to perform big data statistics and operator decision making.

In the embodiment of the present disclosure, during the random access process between the terminal and the secondary node, the reporting information for the target access status of the secondary node is recorded, and the reporting information is sent to the network device, thereby improving 5G and subsequent The communication flow of the communication system ensures the reliability of network communication.
