[0042] To better understand the information reporting method and apparatus disclosed in this disclosure, the communication system to which this disclosure applies will be described first.
[0043] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of the present disclosure. The communication system may include, but is not limited to, a network-side device and a terminal device. Figure 1 The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this disclosure. In actual applications, there may be two or more network-side devices and two or more terminal devices. Figure 1 The communication system 10 shown is exemplified by including a network-side device 101 and a terminal device 102.
[0044] It should be noted that the technical solutions of this disclosure can be applied to various communication systems. For example, Long Term Evolution (LTE) systems, 5th Generation (5G) mobile communication systems, 5G New Radio (NR) systems, or other future new mobile communication systems.
[0045] The network-side device 101 in this embodiment is a network-side entity used for transmitting or receiving signals. For example, the network-side device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. This disclosure does not limit the specific technology or device form used in the base station. The base station provided in this disclosure can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure, the base station, for example, can have its protocol layer separated. Some protocol layer functions are centrally controlled by the CU, while the remaining or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.
[0046] The terminal device 102 in this disclosure is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. This disclosure does not limit the specific technology or device form used in the terminal device.
[0047] It is understood that the communication system described in the embodiments of this disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and does not constitute a limitation on the technical solutions provided in the embodiments of this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this disclosure are also applicable to similar technical problems.
[0048] In addition, the following points are provided to facilitate understanding of the embodiments disclosed herein.
[0049] First, in this embodiment of the disclosure, "for indicating" can include both direct and indirect indication. When describing information as indicating A, it can include whether the information directly indicates A or indirectly indicates A, but does not necessarily mean that the information carries A.
[0050] The information indicated by the information is called the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as, but not limited to, directly indicating the information to be indicated, such as the information to be indicated itself or its index. It can also be indirectly indicated by indicating other information, where there is a relationship between the other information and the information to be indicated. It can also indicate only a part of the information to be indicated, while the other parts are known or pre-agreed upon. For example, the indication of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing the indication overhead to some extent.
[0051] The information to be instructed can be sent as a whole or divided into multiple sub-information messages, and the sending period and / or timing of these sub-information messages can be the same or different. This disclosure does not limit the specific sending method. The sending period and / or timing of these sub-information messages can be predefined, for example, according to a protocol.
[0052] Second, this disclosure provides multiple implementation methods to clearly illustrate the technical solutions of this disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.
[0053] In this embodiment of the disclosure, when a connection establishment fails or a connection recovery fails, the terminal device stores a connection establishment failure report. Upon the next access to the network-side device, it notifies the network-side device of the availability of a available connection establishment failure report via a connection establishment complete / connection recovery complete / connection reconstruction complete / connection reconfiguration complete message. The network-side device can request a connection establishment failure report via a terminal device information request message, and the terminal device carries the connection establishment failure report via a terminal device information response message. Version 17 (R-17) introduces support for the terminal device to record multiple connection establishment failure reports. The content of the connection establishment failure report is as follows:
[0054]
[0055] The perRAInfoList-r16 field is mandatory for each random access information list. The format of perRAInfoList-r16 is as follows:
[0056]
[0057] For each SSB (synchronization signal block), if the terminal device uses its associated random access resource to send a preamble, there will be a PerRASSBInfo-r16 record for each random access SSB. As can be seen above, the perRAAttemptInfoList-r16 field, which contains information related to each random access attempt, is mandatory. The perRAAttemptInfoList-r16 field contains the following:
[0058]
[0059] In related technologies, for NR-U (New Radio Unlicensed), whether a terminal device can send a preamble depends on whether it can successfully perform LBT (listen-before-talk). If the terminal device fails to send the corresponding LBT for the preamble, it cannot send the preamble. It is unclear whether the perRAAttemptInfoList-r16 list of information related to each random access attempt contains information about random access attempts (RA attempts) that failed to send the preamble due to LBT failure.
[0060] Similarly, after a radio link failure (RLF) occurs, the terminal device will also record an RLF report, reporting it in a manner similar to a connection establishment failure report. If the RLF is caused by a handover failure, the terminal device's RLF report will include the random access common information (ra-InformationCommon), which must also carry perRAInfoList-r16. Additionally, the random access report (RA report) and successful handover reports will also include ra-InformationCommon. Secondary cell group (SCG) failure information will carry perRAInfoList-r16. Therefore, the same issues will arise.
[0061] Based on this, this disclosure provides an information reporting method. When a terminal device sends a random access preamble using random access resources associated with a reference signal, it reports random access attempt-related information on the reference signal to the network-side device. Thus, when a terminal device sends a random access preamble using random access resources associated with a reference signal, it can support reporting random access attempt-related information on the reference signal to the network-side device.
[0062] The information reporting method and apparatus provided in this disclosure will now be described in detail with reference to the accompanying drawings.
[0063] Please see Figure 2 , Figure 2 This is a flowchart of an information reporting method provided in an embodiment of this disclosure. For example... Figure 2 As shown, the method may include, but is not limited to, the following steps:
[0064] S21: In response to sending a random access preamble using random access resources associated with a reference signal, the terminal device reports information related to the random access attempt on the reference signal to the network-side device, wherein the reference signal is an SSB or a CSI-RS.
[0065] In this embodiment of the disclosure, when the terminal device sends a random access preamble using the random access resources associated with the reference signal, it reports information related to the random access attempt on the reference signal to the network-side device.
[0066] The scenario where a terminal device sends a random access preamble using random access resources associated with a reference signal can include: scenario 1: the terminal device sends a random access preamble using random access resources associated with a reference signal without performing LBT; scenario 2: the terminal device sends a random access preamble using random access resources associated with a reference signal, and LBT is successful, thus successfully sending the random access preamble; scenario 3: the terminal device sends a random access preamble using random access resources associated with a reference signal, but LBT fails and the preamble is not successfully sent, and so on.
[0067] In some possible implementations, the terminal device sends a random access preamble using the random access resources associated with the reference signal, including case one: the terminal device sends a random access preamble using the random access resources associated with the reference signal without performing LBT. In this case, the terminal device reports information related to the random access attempt on the reference signal to the network-side device, which may include information related to the terminal device sending the random access preamble using the random access resources associated with the reference signal.
[0068] In some possible implementations, the terminal device uses the random access resources associated with the reference signal to send a random access preamble, including case two: the terminal device uses the random access resources associated with the reference signal to send a random access preamble, and LBT is successful, and the random access preamble is successfully sent. In this case, the terminal device reports the random access attempt information on the reference signal to the network side device, which may include the information that the terminal device successfully sent the random access preamble using the random access resources associated with the reference signal.
[0069] In some possible implementations, the terminal device uses the random access resources associated with the reference signal to send a random access preamble, including case three: the terminal device uses the random access resources associated with the reference signal to send a random access preamble, but LBT fails and the transmission is unsuccessful. In this case, the terminal device reports the random access attempt information on the reference signal to the network side device, which may include information about the terminal device using the random access resources associated with the reference signal to send a random access preamble and LBT failing.
[0070] The terminal equipment uses random access resources associated with a reference signal to send a preamble for random access. The reference signal can be an SSB or a CSI-RS.
[0071] In this embodiment of the disclosure, when the terminal device sends a random access preamble using the random access resources associated with the SSB, it reports information related to the random access attempt on the SSB to the network-side device.
[0072] For example, when the reference signal is SSB, if the terminal device sends a random access preamble using the random access resource associated with SSB#1, it reports the random access attempt information on SSB#1 to the network-side device.
[0073] In this embodiment of the disclosure, when the terminal device sends a random access preamble using the random access resources associated with CSI-RS, it reports information related to the random access attempt on CSI-RS to the network-side device.
[0074] For example, when the reference signal is CSI-RS, if the terminal device sends a random access preamble using the random access resources associated with CSI-RS#1, it reports the random access attempt information on CSI-RS#1 to the network-side device.
[0075] In this embodiment of the present disclosure, when the terminal device sends a random access preamble using the random access resources associated with the reference signal, it can store the random access attempt information on the reference signal in advance, and report the random access attempt information on the reference signal to the network side device when the network side device requests to report.
[0076] In this embodiment of the present disclosure, when the terminal device sends a random access preamble using random access resources associated with a reference signal, it reports random access attempt-related information on the reference signal to the network-side device. Thus, the network-side device can receive the random access attempt-related information on the reference signal reported by the terminal device. The random access attempt-related information on the reference signal is reported by the terminal device when sending a random access preamble using random access resources associated with the reference signal, and the reference signal is SSB or CSI-RS.
[0077] In some embodiments, in response to sending a random access preamble using random access resources associated with a reference signal, the terminal device reports information related to the random access attempt on the reference signal to the network-side device, including:
[0078] In response to the successful transmission of a random access preamble using the random access resources associated with the reference signal, the system reports information related to the random access attempt on the reference signal to the network-side device; or
[0079] In response to the transmission of a random access preamble using random access resources associated with a reference signal, and the LBT failure preventing successful transmission, the system reports information related to the random access attempt on the reference signal to the network-side device; or
[0080] In response to the failure to successfully transmit a random access preamble using the random access resources associated with any of the reference signals, one or more reference signals are selected from the reference signals, and information related to the random access attempt on the selected one or more reference signals is reported to the network-side device.
[0081] In this embodiment of the present disclosure, when the terminal device sends a random access preamble using the random access resources associated with the reference signal, it reports random access attempt-related information on the reference signal to the network-side device, including: when the random access preamble is successfully sent using the random access resources associated with the reference signal, reporting random access attempt-related information on the reference signal to the network-side device.
[0082] In this embodiment of the disclosure, when the terminal device sends a random access preamble using random access resources associated with the reference signal, it reports random access attempt-related information on the reference signal to the network-side device, including: when sending a random access preamble using random access resources associated with the reference signal and the LBT fails to send successfully, reporting random access attempt-related information on the reference signal to the network-side device.
[0083] In this embodiment of the present disclosure, when the terminal device sends a random access preamble using random access resources associated with a reference signal, it reports random access attempt-related information on the reference signal to the network-side device, including: when it fails to successfully send a random access preamble using random access resources associated with any reference signal, it selects one or more reference signals from the reference signals and reports random access attempt-related information on the selected one or more reference signals to the network-side device.
[0084] It should be noted that the above embodiments are not exhaustive, but only illustrative of some embodiments. Furthermore, the above embodiments can be implemented individually or in combination. The above embodiments are only illustrative and are not intended to limit the scope of protection of the embodiments disclosed herein.
[0085] In some embodiments, each preamble transmission attempt for random access using random access resources associated with the reference signal is counted as a random access attempt on the reference signal, regardless of whether the LBT is successful. The information related to the random access attempt on the reference signal includes the information related to each random access attempt on the reference signal.
[0086] In this embodiment of the disclosure, the terminal device reports to the network-side device information related to random access attempts on the reference signal, including information related to each random access attempt on the reference signal.
[0087] In particular, each preamble transmission attempt for random access using random access resources associated with the reference signal is counted as a random access attempt on the reference signal, regardless of whether the LBT is successful.
[0088] In this embodiment of the disclosure, each random access preamble transmission attempt is counted as one random access attempt, regardless of whether LBT is successful. If the random access attempt information on the reference signal includes the information related to each random access attempt on the reference signal, the terminal device can report the random access attempt information on the reference signal to the network side device without being configured with lbt-FailureRecoveryConfig.
[0089] In some embodiments, when a random access preamble is transmitted using random access resources associated with a reference signal and the LBT fails to transmit successfully, this is considered a random access attempt on the reference signal. The information related to the random access attempt on the reference signal includes: information related to the transmission of the random access preamble using random access resources associated with the reference signal and the LBT failing to transmit successfully.
[0090] In some embodiments, information related to random access attempts on the reference signal includes at least one of the following:
[0091] The downlink reference signal received power is greater than the threshold dlRSRPAboveThreshold;
[0092] The preamble transmission for random access failed due to LBT failure.
[0093] In this embodiment of the disclosure, if the transmission of the random access preamble fails due to LBT failure during a random access attempt, the terminal device reports random access attempt-related information on the reference signal, including dlRSRPAboveThreshold, to the network-side device. For example, the terminal device reports random access attempt-related information on the reference signal, including dlRSRPAboveThreshold-r16, to the network-side device.
[0094] In this embodiment of the disclosure, if the transmission of the random access preamble fails due to LBT failure during a random access attempt, the terminal device reports the random access attempt-related information on the reference signal to the network-side device, including the failure of the random access preamble transmission due to LBT failure.
[0095] It should be noted that the above embodiments are not exhaustive, but only illustrative of some embodiments. Furthermore, the above embodiments can be implemented individually or in combination. The above embodiments are only illustrative and are not intended to limit the scope of protection of the embodiments disclosed herein.
[0096] In some embodiments, information related to random access attempts on the reference signal does not include at least one of the following:
[0097] ContentionDetected is used for contention detection.
[0098] Fallback to four-step random access fallbackToFourStepRA.
[0099] In this embodiment of the disclosure, if the transmission of the random access preamble fails due to LBT failure for a random access attempt, the terminal device reports random access attempt-related information on the reference signal to the network-side device, excluding contentionDetected. For example, the terminal device reports random access attempt-related information on the reference signal to the network-side device, excluding contentionDetected-r16.
[0100] In this embodiment of the disclosure, if the transmission of the random access preamble fails due to LBT failure during a random access attempt, the terminal device reports random access attempt-related information on the reference signal to the network-side device, excluding fallbackToFourStepRA. For example, the terminal device reports random access attempt-related information on the reference signal to the network-side device, excluding fallbackToFourStepRA-r17.
[0101] It should be noted that the above embodiments are not exhaustive, but only illustrative of some embodiments. Furthermore, the above embodiments can be implemented individually or in combination. The above embodiments are only illustrative and are not intended to limit the scope of protection of the embodiments disclosed herein.
[0102] In some embodiments, for each random access preamble transmission attempt using random access resources associated with a reference signal, only if the random access preamble is successfully transmitted is it counted as a random access attempt on the reference signal. The information related to the random access attempt on the reference signal includes the information related to each random access attempt on the reference signal.
[0103] In this embodiment of the disclosure, for each random access preamble transmission attempt using the random access resources associated with the reference signal, only if the random access preamble is successfully transmitted is it counted as a random access attempt on the reference signal. In this case, the terminal device reports the random access attempt related information on the reference signal to the network side device, including the relevant information of each random access attempt on the reference signal, such as the relevant information of successfully transmitting the random access preamble using the random access resources associated with the reference signal.
[0104] In this embodiment of the disclosure, for each random access preamble transmission attempt using the random access resources associated with the reference signal, only if the random access preamble is successfully transmitted is it counted as a random access attempt on the reference signal. The information related to the random access attempt on the reference signal includes the information related to each random access attempt on the reference signal. In this case, the terminal device reports the information related to the random access attempt on the reference signal to the network side device only if lbt-FailureRecoveryConfig is configured.
[0105] In this embodiment of the disclosure, for each random access preamble transmission attempt using the random access resources associated with the reference signal, only if the random access preamble is successfully transmitted is it counted as a random access attempt on the reference signal. The terminal device records random access attempt-related information for the random access attempts on the reference signal, including the number of times the random access preamble was transmitted using the random access resources associated with the reference signal before the random access preamble was successfully transmitted using the random access resources associated with the reference signal, and the number of consecutive LBT failures that prevented successful transmission.
[0106] In some embodiments, the terminal device reports information related to random access attempts on a reference signal to the network-side device, including: reporting a list of random access information to the network-side device, wherein the list of random access information includes information related to random access attempts on the reference signal.
[0107] In this embodiment of the disclosure, the terminal device reports random access attempt-related information on the reference signal to the network-side device. It may report a newly defined random access information list (PerRAInfoList), for example: PerRAInfoList-r18, which includes fields for indicating information related to each random access attempt.
[0108] In some possible implementations, if PerRAInfoList-r16 is a required field in the existing report information element IE, the report IE can be redefined. For example, this could be used for connection establishment failure reports or random access reports. The redefined report would contain the newly defined PerRAInfoList.
[0109] In some possible implementations, if PerRAInfoList-r16 is an optional field in the existing report, the newly defined PerRAInfoList-r18 version can be used instead of the PerRAInfoList-r16 version. Examples include: RLF reports due to handover failures or random access issues; successful handover reports triggered by timer T304; and SCG failure information reports triggered by random access failures or SCG additions / changes.
[0110] In some possible implementations, the terminal device may use the newly defined PerRAInfoList only when the preamble transmission count on an SSB or CSI-RS is 0. Alternatively, it may use the newly defined PerRAInfoList for all cases.

Furthermore, the above embodiments can be implemented individually or in combination. The above embodiments are only illustrative and are not intended to limit the scope of protection of the embodiments disclosed herein.
[0127] In this embodiment of the disclosure, before reporting any of the following reports to the network-side device: connection establishment failure report, random access report, RLF report, SCG failure information, successful handover report, PScell successful addition report, and PScell successful change report, the terminal device may first record the random access attempt information on the reference signal in the variable corresponding to the report.

[0128] By implementing embodiments of this disclosure, when a terminal device transmits a random access preamble using random access resources associated with a reference signal, it reports random access attempt-related information on that reference signal to the network-side device. The reference signal is either an SSB or a CSI-RS. Therefore, the terminal device supports reporting random access attempt-related information on that reference signal to the network-side device when transmitting a random access preamble using random access resources associated with that reference signal.
[0129] Please see Figure 3 , Figure 3 This is a flowchart of another information reporting method provided in this embodiment of the disclosure. For example... Figure 3 As shown, the method may include, but is not limited to, the following steps:
[0130] S31: In response to successfully sending a random access preamble using the random access resources associated with the reference signal, the terminal device reports information related to the random access attempt on the reference signal to the network-side device, wherein the reference signal is SSB or CSI-RS.
[0131] In this embodiment of the disclosure, when the terminal device successfully sends a random access preamble using the random access resources associated with the reference signal, it reports information related to the random access attempt on the reference signal to the network-side device.
[0132] Among them, the case where the terminal device successfully transmits the preamble of random access using the random access resources associated with the reference signal can include the case where the terminal device transmits the preamble of random access using the random access resources associated with the reference signal and successfully performs LBT, thus successfully transmitting the preamble of random access.
[0133] In this embodiment of the disclosure, the terminal device only reports information related to the random access attempt on the reference signal to the network side device if it successfully sends a random access preamble using a random access resource associated with a reference signal.
[0134] For example, when the reference signal is SSB, the terminal device reports information related to the random access attempt on SSB#1 to the network-side device only if it successfully sends the preamble of random access using the random access resource associated with SSB#1.
[0135] For example, when the reference signal is CSI-RS, the terminal device reports information related to the random access attempt on CSI-RS#1 to the network-side device only if it successfully sends the preamble of random access using the random access resources associated with CSI-RS#1.
[0136] In some embodiments, if the terminal device successfully sends a random access preamble using the random access resources associated with the reference signal and is not configured with lbt-FailureRecoveryConfig, it reports information related to the random access attempt on the reference signal to the network-side device, wherein the reference signal is SSB or CSI-RS.

The embodiments of this disclosure do not limit this.
[0139] By implementing embodiments of this disclosure, when a terminal device successfully transmits a random access preamble using random access resources associated with a reference signal, it reports random access attempt-related information on that reference signal to the network-side device. The reference signal is either an SSB or a CSI-RS. Therefore, the terminal device supports reporting random access attempt-related information on that reference signal to the network-side device when it successfully transmits a random access preamble using random access resources associated with that reference signal.

[0141] S41: In response to the terminal device sending a random access preamble using the random access resource associated with the reference signal, and the LBT failing to send successfully, the terminal device reports information related to the random access attempt on the reference signal to the network side device, wherein the reference signal is SSB or CSI-RS.
[0142] In this embodiment of the disclosure, if the terminal device sends a random access preamble using the random access resources associated with the reference signal and the LBT fails to send it successfully, it reports the random access attempt information on the reference signal to the network side device.
[0143] For example, when the reference signal is SSB, if the terminal device sends a random access preamble using the random access resource associated with SSB#1 and the LBT fails to send it successfully, it reports the random access attempt information on SSB#1 to the network side device.
[0144] For example, when the reference signal is CSI-RS, if the terminal device sends a random access preamble using the random access resource associated with CSI-RS#1 and the LBT fails to send it successfully, it reports the random access attempt information on CSI-RS#1 to the network-side device.
[0145] The content of the information related to random access attempts on the reference signal reported by the terminal device to the network-side device, and the method of reporting such information to the network-side device, can be found in the relevant descriptions in the above embodiments, and will not be repeated here.
[0146] It should be noted that in the embodiments of this disclosure, S41 can be implemented alone or in combination with any other step in the embodiments of this disclosure, such as in combination with S21 in the embodiments of this disclosure. The embodiments of this disclosure do not limit this.
[0147] By implementing embodiments of this disclosure, when a terminal device transmits a random access preamble using random access resources associated with a reference signal, and the LBT fails to transmit successfully, it reports information related to the random access attempt on the reference signal to the network-side device. The reference signal is either an SSB or CSI-RS. Therefore, the terminal device supports reporting information related to the random access attempt on the reference signal to the network-side device when transmitting a random access preamble using random access resources associated with a reference signal, and the LBT fails to transmit successfully.
[0148] Please see Figure 5 , Figure 5 This is a flowchart of another information reporting method provided in this disclosure embodiment. For example... Figure 5 As shown, the method may include, but is not limited to, the following steps:
[0149] S51: In response to the failure to successfully transmit a random access preamble using the random access resource associated with any reference signal, the terminal device selects one or more reference signals and reports information related to the random access attempt on the selected one or more reference signals to the network-side device, wherein the reference signal is an SSB or a CSI-RS.
[0150] In this embodiment of the disclosure, if the terminal device fails to successfully send a random access preamble using the random access resources associated with any of the reference signals, it can select one or more reference signals and report information related to the random access attempt on the selected one or more reference signals to the network-side device.
[0151] In this process, the terminal device selects one or more reference signals. It may choose to use the random access resources associated with the reference signal to send the reference signal used first in the random access preamble, or it may choose to use the random access resources associated with the reference signal to send the reference signal used last in the random access preamble, or it may choose to use the random access resources associated with the reference signal to send the reference signal used most frequently in the random access preamble, or it may choose to use the random access resources associated with the reference signal to send the reference signal with the worst downlink RSRP (Reference Signal Received Power) in the random access preamble, etc. The embodiments disclosed herein do not impose specific limitations on this.
[0152] In this process, the terminal device selects one or more reference signals. It may select the first one to try, or the last one to try, or the one with the most attempts, or the one with the worst downlink RSRP (Reference Signal Received Power), etc. The embodiments disclosed herein do not impose specific limitations on this.
[0153] For example, when the reference signal is an SSB, if the terminal device fails to successfully send a random access preamble using the random access resources associated with SSB#1, SSB#2, and SSB#3, it can select one or more target reference signals from SSB#1, SSB#2, and SSB#3. If SSB#3 is selected as the target reference signal, the terminal device can report the random access attempt information on SSB#3 to the network-side device.
[0154] For example, when the reference signal is CSI-RS, if the terminal device fails to successfully send a random access preamble using the random access resources associated with CSI-RS#1, CSI-RS#2, and CSI-RS#3, it can select one or more target reference signals from CSI-RS#1, CSI-RS#2, and CSI-RS#3. If CSI-RS#2 is selected as the target reference signal, the terminal device can report the random access attempt information on CSI-RS#2 to the network side device.
[0155] In this embodiment of the disclosure, if the terminal device fails to successfully send a random access preamble using the random access resources associated with any of the reference signals, it can select one or more reference signals and report information related to the random access attempt on the selected one or more reference signals to the network-side device. This method is only applicable to connection establishment failure reports, RLF reports caused by handover failure or random access problems, random access reports caused by random access failure, successful handover reports triggered by T304, and SCG failure information reports triggered by random access failure or SCG addition / change.
[0156] The content of the information related to random access attempts on the reference signal reported by the terminal device to the network-side device, and the method of reporting such information to the network-side device, can be found in the relevant descriptions in the above embodiments, and will not be repeated here.
[0157] It should be noted that in the embodiments of this disclosure, S51 can be implemented alone or in combination with any other step in the embodiments of this disclosure, such as in combination with S21 in the embodiments of this disclosure. The embodiments of this disclosure do not limit this.
[0158] By implementing embodiments of this disclosure, when a terminal device fails to successfully transmit a random access preamble using random access resources associated with any of the reference signals, it selects one or more reference signals and reports information related to the random access attempt on the selected one or more reference signals to the network-side device, wherein the reference signals are SSBs or CSI-RSs. Thus, the terminal device supports selecting one or more reference signals and reporting information related to the random access attempt on the selected one or more reference signals to the network-side device when it fails to successfully transmit a random access preamble using random access resources associated with any of the reference signals.
[0159] Please see Figure 6 , Figure 6 This is a flowchart of another information reporting method provided in this disclosure embodiment. For example... Figure 6 As shown, the method may include, but is not limited to, the following steps:
[0160] S61: In response to sending a random access preamble using the random access resources associated with the reference signal, and without being configured with lbt-FailureRecoveryConfig, the terminal device reports information related to the random access attempt on the reference signal to the network-side device. The reference signal is either an SSB or a CSI-RS. The information related to the random access attempt on the reference signal includes information related to each random access attempt on the reference signal. For each random access preamble sending attempt using the random access resources associated with the reference signal, regardless of whether the LBT is successful, it is counted as a random access attempt on the reference signal.
[0161] In this embodiment of the disclosure, the terminal device reports to the network-side device information related to random access attempts on the reference signal, including information related to each random access attempt on the reference signal.
[0162] In particular, each preamble transmission attempt for random access using random access resources associated with the reference signal is counted as a random access attempt on the reference signal, regardless of whether the LBT is successful.
[0163] In this embodiment of the disclosure, each random access preamble transmission attempt is counted as one random access attempt, regardless of whether LBT is successful. If the random access attempt information on the reference signal includes the information related to each random access attempt on the reference signal, the terminal device can report the random access attempt information on the reference signal to the network side device without being configured with lbt-FailureRecoveryConfig.
[0164] In some embodiments, when a random access preamble is transmitted using random access resources associated with a reference signal and the LBT fails to transmit successfully, this is considered a random access attempt on the reference signal. The information related to the random access attempt on the reference signal includes: information related to the transmission of the random access preamble using random access resources associated with the reference signal and the LBT failing to transmit successfully.
[0165] In this embodiment of the disclosure, when a random access preamble is sent using random access resources associated with a reference signal, and the LBT fails to transmit successfully, which is considered a random access attempt on the reference signal, the terminal device reports the following information to the network-side device: information related to the random access attempt on the reference signal, including information about sending a random access preamble using random access resources associated with the reference signal and the LBT failing to transmit successfully.
[0166] In some embodiments, information related to random access attempts on the reference signal includes at least one of the following:
[0167] The downlink reference signal received power is greater than the threshold dlRSRPAboveThreshold;
[0168] The preamble transmission for random access failed due to LBT failure.
[0169] In this embodiment of the disclosure, if the transmission of the random access preamble fails due to LBT failure during a random access attempt, the terminal device reports random access attempt-related information on the reference signal, including dlRSRPAboveThreshold, to the network-side device. For example, the terminal device reports random access attempt-related information on the reference signal, including dlRSRPAboveThreshold-r16, to the network-side device.
[0170] In this embodiment of the disclosure, if the transmission of the random access preamble fails due to LBT failure during a random access attempt, the terminal device reports the random access attempt-related information on the reference signal to the network-side device, including the failure of the random access preamble transmission due to LBT failure.
[0171] It should be noted that the above embodiments are not exhaustive, but only illustrative of some embodiments. Furthermore, the above embodiments can be implemented individually or in combination. The above embodiments are only illustrative and are not intended to limit the scope of protection of the embodiments disclosed herein.
[0172] In some embodiments, information related to random access attempts on the reference signal does not include at least one of the following:
[0173] ContentionDetected is used for contention detection.
[0174] Fallback to four-step random access fallbackToFourStepRA.
[0175] In this embodiment of the disclosure, if the transmission of the random access preamble fails due to LBT failure for a random access attempt, the terminal device reports random access attempt-related information on the reference signal to the network-side device, excluding contentionDetected. For example, the terminal device reports random access attempt-related information on the reference signal to the network-side device, excluding contentionDetected-r16.
[0176] In this embodiment of the disclosure, if the transmission of the random access preamble fails due to LBT failure during a random access attempt, the terminal device reports random access attempt-related information on the reference signal to the network-side device, excluding fallbackToFourStepRA. For example, the terminal device reports random access attempt-related information on the reference signal to the network-side device, excluding fallbackToFourStepRA-r17.
[0177] It should be noted that the above embodiments are not exhaustive, but only illustrative of some embodiments. Furthermore, the above embodiments can be implemented individually or in combination. The above embodiments are only illustrative and are not intended to limit the scope of protection of the embodiments disclosed herein.
[0178] The method by which the terminal device reports information related to random access attempts on the reference signal to the network-side device can be found in the relevant description in the above embodiments, and will not be repeated here.
[0179] It should be noted that in the embodiments of this disclosure, S61 can be implemented alone or in combination with any other step in the embodiments of this disclosure, such as in combination with S21 and / or S31 and / or S41 and / or S51 in the embodiments of this disclosure. The embodiments of this disclosure do not limit this.
[0180] By implementing the embodiments of this disclosure, when the terminal device is not configured with the LBT-FailureRecoveryConfig for listening failure recovery, it reports information related to random access attempts on a reference signal to the network-side device. The reference signal is either an SSB or CSI-RS. Each attempt to send a preamble for random access using the random access resources associated with the reference signal is counted as one random access attempt on the reference signal, regardless of whether the LBT is successful. The information related to random access attempts on the reference signal includes information related to each random access attempt on the reference signal. Therefore, the terminal device supports sending a preamble for random access using the random access resources associated with the reference signal and reporting information related to random access attempts on the reference signal to the network-side device even without LBT-FailureRecoveryConfig being configured. The information related to random access attempts on the reference signal includes information related to each random access attempt on the reference signal. Each attempt to send a preamble for random access using the random access resources associated with the reference signal is counted as one random access attempt on the reference signal, regardless of whether the LBT is successful.
[0181] Please see Figure 7 , Figure 7 This is a flowchart of another information reporting method provided in this disclosure embodiment. For example... Figure 7 As shown, the method may include, but is not limited to, the following steps:
[0182] S71: The terminal device responds to sending a random access preamble using the random access resources associated with the reference signal and is configured with lbt-FailureRecoveryConfig, and reports information related to the random access attempt on the reference signal to the network-side device. The reference signal is either an SSB or a CSI-RS. The information related to the random access attempt on the reference signal includes information related to each random access attempt on the reference signal. For each random access preamble sending attempt using the random access resources associated with the reference signal, only if the random access preamble is successfully sent is it counted as a random access attempt on the reference signal.
[0183] In this embodiment of the disclosure, for each random access preamble transmission attempt using the random access resources associated with the reference signal, only if the random access preamble is successfully transmitted is it counted as a random access attempt on the reference signal. In this case, the terminal device reports the random access attempt related information on the reference signal to the network side device, including the relevant information of each random access attempt on the reference signal, such as the relevant information of successfully transmitting the random access preamble using the random access resources associated with the reference signal.
[0184] In this embodiment of the disclosure, for each random access preamble transmission attempt using the random access resources associated with the reference signal, only if the random access preamble is successfully transmitted is it counted as a random access attempt on the reference signal. The information related to the random access attempt on the reference signal includes the information related to each random access attempt on the reference signal. In this case, the terminal device reports the information related to the random access attempt on the reference signal to the network side device only if lbt-FailureRecoveryConfig is configured.
[0185] In this embodiment of the disclosure, for each random access preamble transmission attempt using the random access resources associated with the reference signal, only if the random access preamble is successfully transmitted is it counted as a random access attempt on the reference signal. The terminal device records random access attempt-related information for the random access attempts on the reference signal, including the number of times the random access preamble was transmitted using the random access resources associated with the reference signal before the random access preamble was successfully transmitted using the random access resources associated with the reference signal, and the number of consecutive LBT failures that prevented successful transmission.
[0186] The method by which the terminal device reports information related to random access attempts on the reference signal to the network-side device can be found in the relevant description in the above embodiments, and will not be repeated here.
[0187] It should be noted that in the embodiments of this disclosure, S71 can be implemented alone or in combination with any other step in the embodiments of this disclosure, such as in combination with S21 and / or S31 and / or S41 and / or S51 in the embodiments of this disclosure. The embodiments of this disclosure do not limit this.
[0188] By implementing the embodiments of this disclosure, when a terminal device transmits a random access preamble using random access resources associated with a reference signal and is configured with lbt-FailureRecoveryConfig, it reports random access attempt-related information on the reference signal to the network-side device. The reference signal is either an SSB or CSI-RS. The random access attempt-related information on the reference signal includes information about each random access attempt on the reference signal. For each random access preamble transmission attempt using random access resources associated with the reference signal, only if the random access preamble is successfully transmitted is it counted as one random access attempt on the reference signal. Therefore, the terminal device supports transmitting a random access preamble using random access resources associated with a reference signal and being configured with lbt-FailureRecoveryConfig, and reporting random access attempt-related information on the reference signal to the network-side device. The random access attempt-related information on the reference signal includes information about each random access attempt on the reference signal. For each random access preamble transmission attempt using random access resources associated with the reference signal, only if the random access preamble is successfully transmitted is it counted as one random access attempt on the reference signal.

[0191] In this embodiment of the disclosure, the terminal device reports random access attempt-related information on the reference signal to the network-side device. It may report a newly defined random access information list (PerRAInfoList), for example: PerRAInfoList-r18, which includes fields for indicating information related to each random access attempt.
[0192] In some possible implementations, if PerRAInfoList-r16 is a required field in the existing report information element IE, the report IE can be redefined. For example, this could be used for connection establishment failure reports or random access reports. The redefined report would contain the newly defined PerRAInfoList.
[0193] In some possible implementations, if PerRAInfoList-r16 is an optional field in the existing report, the newly defined PerRAInfoList-r18 version can be used instead of the PerRAInfoList-r16 version. Examples include: RLF reports due to handover failures or random access issues; successful handover reports triggered by timer T304; and SCG failure information reports triggered by random access failures or SCG additions / changes.
[0194] In some possible implementations, the terminal device may use the newly defined PerRAInfoList only when the number of preamble transmissions for random access on an SSB or CSI-RS is 0. Alternatively, the newly defined PerRAInfoList may be used for all access attempts. When the number of preamble transmissions for random access is 0, the fields containing information related to random access attempts are not reported.
[0195] It should be noted that the random access information list includes information related to random access attempts on the reference signal. The contents of the information related to random access attempts on the reference signal can be found in the relevant descriptions in the above embodiments, and will not be repeated here.
[0196] It should be noted that in the embodiments of this disclosure, S81 can be implemented alone or in combination with any other step in the embodiments of this disclosure, such as in combination with S21 and / or S31 and / or S41 and / or S51 and / or S61 and / or S71 in the embodiments of this disclosure.
