Description

[Technical field]

[0001] Cross-reference to related applications This application claims priority to Chinese Patent Application No. 210811620322.0, entitled "RANDOM ACCESS STATISTICS INFORMATION REPORTING METHOD AND DEVICE," filed on December 27, 2018, the entire contents of which are incorporated herein by reference.

[0002] Technical Field The present disclosure relates generally to the field of mobile communications, and more particularly to a random access statistics reporting method and device.

[0003] Random access is widely applied in the mobile communications field, for example, in uplink synchronization between terminals and base stations, and in Cell Radio Network Temporary Identifier (C-RNTI) and beam restoration. Random access procedures are triggered by Radio Resource Control (RRC) link establishment, RRC link re-establishment, handover, uplink and downlink data arrival, RRC hold, beam failure recovery, system information request, and other events.

[0004] In existing techniques, there are two random access procedures: contention-based random access and non-contention-based random access. In contention-based random access, the terminal sends message (msg)1 to the base station, the base station sends msg2 to the terminal, the terminal sends msg3 to the base station, and the base station sends msg4 to the terminal. If the terminal recognizes in msg4 that this is a message sent to itself, the random access is considered successful. Another contention-based random access method is a two-step method. That is, the terminal sends msgA to the base station, and the base station sends msgB to the terminal, resolving the collision by two steps. In non-contention-based random access, the base station allocates dedicated random access resources to the terminal. The terminal sends msg1 (including a dedicated preamble sequence) to the base station, the base station sends msg2 to the terminal, the terminal receives msg2 and can confirm that msg2 was sent to itself, then this random access is considered successful. Summary of the Invention [Problem to be solved by the invention]

[0042] Please refer to FIG. 1, which is a flow chart of a method for reporting random access statistics according to an embodiment.

[0043] In S11, statistical information of the random access procedure is obtained.

[0044] In S12, the statistical information and type information are reported to the base station, where the type information is used to indicate a random access type corresponding to the statistical information.

[0045] In one embodiment, the terminal counts all types of random access procedures to obtain statistical information of the random access procedures, and reports the statistical information of the random access procedures to the base station, the information reported by the terminal further including type information used to indicate the random access type corresponding to the statistical information of the random access procedures.

[0046] In an embodiment, the step of obtaining the statistical information of the random access procedure includes the steps of receiving configuration information from the base station, the configuration information including a random access type corresponding to the statistical information, and obtaining the statistical information of the random access procedure based on the configuration information, i.e., the terminal does not need to count all types of random procedures, but only needs to count some types of random procedures based on the configuration information to obtain the corresponding statistical information.

[0047] In one embodiment, prior to reporting the statistical information and type information to the base station, the method further includes the steps of sending first indication information to the base station, the first indication information being used to indicate that the terminal has statistical information to report, receiving first acknowledgement information from the base station, and determining whether to report the statistical information based on the first acknowledgement information.

[0048] In one embodiment, the step of reporting the statistical information and type information to the base station includes the steps of sending second instruction information to the base station, where the second instruction information is used to indicate a random access type of the statistical information that can be reported by the terminal, receiving second acknowledgement information from the base station, where the second acknowledgement information is used to indicate a random access type corresponding to the statistical information that the terminal needs to report, and reporting the statistical information and type information to the base station based on the second acknowledgement information.

[0049] In an embodiment, due to the possibility of channel congestion and large amount of statistical information, the terminal does not need to report all statistical information all the time. Regardless of whether the terminal receives configuration information from the base station, before reporting the statistical information and type information, the terminal receives indication information from the base station, and can report some or all of the statistical information or not report all of the information based on the indication information. Therefore, the terminal only needs to count and report the random access statistics according to the requirements of the base station, thereby reducing the resource overhead for reporting the random access statistics.

[0050] In one embodiment, the random access types include normal random access, system information request random access, and beam failure recovery random access. The configuration information can include one or more of these random access types.

[0051] In one embodiment, normal random access refers to a random access procedure initiated for uplink synchronization or C-RNTI acquisition, including random access induced by the RRC protocol layer and the Medium Access Control (MAC) protocol layer. The purpose of the system information request random access is to obtain system information. The purpose of the beam failure recovery random access is to perform beam failure recovery.

[0052] In one embodiment, the normal random access statistics information includes one or more of cell identity information, the number of preambles sent during a successful random access procedure, whether a contention resolution failure occurred during a successful random access procedure, high priority random access parameter information, beam information, bandwidth portion information, or reason information for random access failure. The base station can optimize normal random access parameters based on the received normal random access statistics information. For example, optimize parameters such as preamble TransMax and power ramping step. Furthermore, the base station can optimize random access parameter configurations for a specific cell, different beams, and different BWPs.

[0053] In an embodiment, the cell identity may be an identity of a cell to which the terminal performs random access.

[0054] In an embodiment, the high priority random access parameter information includes at least one of the use instruction information or the high priority random access parameters. The use instruction information is used to indicate whether or not the high priority parameters are used in the random access procedure. The high priority random access parameters that must be reported are the high priority parameters used in the random access procedure and include at least one of the power ramping step high priority and the time backoff scaling factor BI. The base station can optimize parameters for normal random access or high priority random access. For example, the power ramping step high priority and / or the time backoff scaling factor can be optimized for the high priority random access.

[0055] In one embodiment, the beam information refers to a beam for initiating random access and can be indicated by a Synchronization Signal Block index (SSB index) or a Channel State Information-Reference Signal index (CSI-RS index).

[0056] In one embodiment, the bandwidth part (BWP) information refers to the bandwidth part where the random access is initiated and can be indicated by a BWP number (ID). If the bandwidth part IDs of the uplink message and the downlink message sent in the random access procedure are different, the bandwidth part information includes an uplink bandwidth part ID and a downlink bandwidth part ID.

[0057] In an embodiment, the reason information for the random access failure includes a random access failure caused by consecutive LBT (Listen Before Talk) failures. The consecutive LBT failures refer to an event in which the number of consecutive LBT failures reaches a certain threshold, or all LBTs fail within a certain time period. The specific threshold and the specific time period may be set by the base station side, or may be pre-set or specified by agreement, and are not limited in the present disclosure. The base station may determine whether to optimize the random access parameters based on the reason for the random access failure. For example, if the random access failure occurs due to an LBT failure, the base station may consider not optimizing the random access parameters, because it is a consecutive LBT failure caused by channel congestion.

[0058] In an embodiment, the step of counting system information request random access procedures by the terminal includes counting successful and / or unsuccessful procedure information of random access to obtain statistical information of system information request random access.

[0059] In one embodiment, the system information request random access statistics include one or more of: random access statistics for system information requests via msg1; random access statistics for system information requests via msg3; the time interval between sending a preamble to request system information and receiving the corresponding system information; or normal random access statistics.

[0060] In one embodiment, the system information request via msg1 refers to requesting system information using msg1 in a random access procedure, and the system information request via msg3 refers to requesting system information using msg3 in a random access procedure. In one embodiment, the indication message information is used by the terminal to indicate whether the random access statistics of the system information request are reported by msg1 or msg3.

[0061] The statistical information about the random access of the system information request by msg1 includes one or more of the following: the number or failure rate of random access failures, the type of system information requested (SI (System Information) 1, SI2, SI3, or SI4), or preamble information. The preamble information includes the preamble sent in the random access procedure and the occurrence of the Physical Random Access Channel (PRACH) used to send the preamble.

[0062] The statistics about the random access of the system information requests by msg3 include one or more of the random access failure count or failure rate of the random access or the type of system information requested.

[0063] In one embodiment, the system information request random access statistics includes one or more items in the regular random access statistics.

[0064] By reporting the statistical information of the system information request random access, the network side can optimize the parameters of the system information request random access procedure based on the received statistical information, and also optimize the related parameters of msg1 and smg3.

[0065] In one embodiment, the step of the terminal counting beam failure recovery random access procedures includes a step of counting successful and / or unsuccessful random access procedure information to obtain beam failure recovery random access statistics information and normal random access statistics information.

[0066] In an embodiment, the beam failure recovery random access statistics include one or more of beam failure information, random access resource type information, or normal random access statistics.

[0067] In an embodiment, the beam failure information includes one or more of the signal quality of the beam where the failure occurred, the signal quality of the beam based on which the random access is initiated, or the signal quality of the beam in the candidate beam reference signal list. The signal quality can be represented by Reference Signal Receiving Power (RSRP) or Reference Signal Receiving Quality (RSRQ). The base station can optimize some parameters in the beam failure recovery mechanism based on the beam failure information, such as the signal quality threshold for determining beam failure and the signal quality threshold for selecting a new beam.

[0068] In an embodiment, the random access resource type information includes one or more of a resource type used for random access or beam failure recovery timer timeout information used to indicate whether a beam failure recovery timer expired when a resource type is selected for random access. The random access resource types include contention-based random access resources and non-contention-based random access resources. The base station can use the resource type information for random access to optimize parameters, such as the length of a beam failure recovery timer or a non-contention-based random access resource configuration for beam failure recovery.

[0069] In one embodiment, the beam failure recovery random access statistics further include normal random access statistics, which have been described above and will not be described in detail here.

[0070] By reporting the beam failure recovery random access statistics, the network side can optimize the parameters of the beam failure recovery random access procedure based on the received statistics.

[0071] From the perspective of resource usage, the random access type further includes uplink random access and supplementary uplink random access.

[0072] The terminal may choose to initiate random access on the uplink or the supplemental uplink based on the cell signal command obtained by the measurement. If the terminal initiates random access on the uplink, it shall count it as a statistic for uplink random access. Or, if the terminal initiates random access on the supplemental uplink, it shall count it as a statistic for supplemental uplink random access.

[0073] In one embodiment, the terminal reports random access statistics to the base station and indicates whether the random access statistics were counted on a supplemental uplink or on an uplink.

[0074] In one embodiment, the uplink indication information is used by the terminal to indicate whether the reported statistics are uplink random access statistics or supplemental uplink random access statistics. For example, the terminal can send the uplink indication information by RRC signaling.

[0075] In an embodiment, the terminal can implicitly indicate whether the statistics are counted on the supplemental uplink or on the uplink. If the terminal reports uplink random access statistics on the uplink of a cell, it can implicitly indicate that the random access statistics are subsequent to the uplink. If the terminal reports supplemental uplink random access statistics on the supplemental uplink of a cell, it can implicitly indicate that the random access statistics are subsequent to the supplemental uplink. The network side can determine whether the statistics are for the supplemental uplink or for the uplink based on the random access statistics received from the supplemental uplink or the uplink.

[0076] In one embodiment, the statistical information may be statistical information corresponding to normal random access, system information request random access, and beam failure recovery random access.

[0077] The terminal reports random access statistics according to the supplementary uplink and uplink, respectively, so that the network side can optimize random access parameters for each different uplink based on the reported supplementary uplink or uplink random access statistics.

[0078] In one embodiment, the contention-based random access initiated by the terminal may include a four-phase random access and a two-phase random access, and the terminal may count the four-phase random access and the two-phase random access separately to obtain statistics information of the four-phase random access and statistics information of the two-phase random access.

[0079] In an embodiment, the terminal can decide whether to initiate two-phase random access or four-phase random access based on an instruction from the base station or based on a condition set by the network, for example, the base station can set a threshold for the terminal, and the terminal can initiate two-phase random access when the signal quality of the detected cell exceeds this threshold, and initiate four-phase random access otherwise.

[0080] In the 2-step random access procedure, the base station can decide whether to back off to 4-step random access. For example, if the base station successfully receives only the preamble part in msgA, the base station sends msg2 to the terminal, and the terminal is considered to back off to 4-step random access.

[0081] In one embodiment, the terminal reports statistical information to the base station, and indicates whether the statistical information is 2-phase random access statistical information or 4-phase random access statistical information by phase indication information.

[0082] In one embodiment, the two-phase random access or four-phase random access statistics may include statistics corresponding to normal random access, system information request random access, and beam failure recovery random access.

[0083] In an embodiment, the 4-phase random access statistics further include backoff information for backoff from 2-phase random access to 4-phase random access, the backoff information including the number of backoffs and / or the backoff ratio within a specific time period, which may refer to the time from when the terminal receives the measurement configuration to when the backoff information is reported.

[0084] In an embodiment, the statistical information of the two-phase random access and the four-phase random access includes condition information for selecting the two-phase random access, and the condition information includes corresponding state information when the terminal satisfies the selection of the two-phase random access. For example, the condition is a threshold, and when the signal quality of the detected cell exceeds the threshold, the terminal initiates the two-phase random access. Here, the state information refers to the signal quality of the cell detected by the terminal.

[0085] Since the terminal reports statistical information for two-phase random access and four-phase random access respectively, the network side can optimize random access parameters for two-phase or four-phase random access, and can further optimize the conditions for inducing two-phase random access, such as optimizing the threshold for inducing two-phase random access.

[0086] In one embodiment, the terminal may report random access statistics to the base station via RRC signaling.

[0087] In an embodiment, the statistics may be reported by at least one of Signaling Radio Bearer (SRB) 1, SRB2, and SRB3.

[0088] In an embodiment, the terminal may determine the SRB to use for reporting the statistics based on the random access type, e.g., normal random access statistics may be reported over SRB1 and system information request random access statistics may be reported over SRB2.

[0089] In an embodiment, prior to reporting the random access procedure statistics to the base station, the method further includes reporting public land mobile network information corresponding to the random access procedure statistics, and the base station can determine whether to instruct the terminal to report the public land mobile network random access statistics based on the public land mobile network information in the request information reported by the terminal.
