    Descriptive Report of the Invention Patent for METHOD AND APPARATUS FOR REQUESTING SYSTEM INFORMATION, USER EQUIPMENT AND BASE STATION. TECHNICAL FIELD [0001] The present invention relates to the field of communication technology and, in particular, to a method and apparatus for requesting system information, user equipment and a base station.
    BACKGROUND [0002] With the rapid development of wireless communication technology, the amount of Long Term Evolution (LTE) System Information (SI) has increased and the sending of SI from LTE in the form of a periodic transmission can make a base station consume more energy and decrease the rate of use of spectrum resources. In the event that the number of User Equipment (UE) accessed is relatively smaller, sending LTE SI in the form of a periodic transmission wastes resources. To mitigate the problems of wasting resources and the increase in energy consumption by the base station caused by sending LTE SI in the form of a transmission, operators begin to consider how to send SI by classification in order to solve the above problems.
    [0003] In a discussion of research on the Fifth Generation mobile communication technology project (5G for short), IS can be classified into a first type of IS and a second type of IS. The first type of SI can include SIs associated with cell selection and cell access, and the second type of SI can include another SI, except for the first type of SI. In the related technique, the first type of SI can still be sent by transmission and for the second type of SI, when a particular preamble for requesting the second type
    Petition 870190103419, of 10/14/2019, p. 5/66
    2/34 of SI sent by the UE via MSG 1 (a first message in a random access process) is received, the second type of SI can be transmitted within a transmission window of the second type of SI requested by the UE. However, in the related technique, the sending of MSG 1 by the UE may fail due to the low energy available to send the MSG 1, which also prevents the base station from transmitting the second type of SI because the request message sent by the UE has not been received. In this case, the UE can only wait for a next SI period to re-request the second type of SI through MSG 1, which results in a longer latency for the UE to obtain the SI and seriously impair performance.
    SUMMARY [0004] The modalities of the present invention provide methods and devices for requesting system information, in order to improve the efficiency of requesting system information to be requested through a random access request, thus avoiding a case in the which system information to be requested is not received successfully or the latency to obtain system information is relatively long when the random access request fails.

    DETAILED DESCRIPTION OF THE MODALITIES [0043] The modalities of the invention will be described in detail with their examples being illustrated in the attached drawings. When the following descriptions involve drawings, the same numerals in different drawings refer to identical or similar elements, unless stated otherwise. The implantation modes described in the exemplary embodiments below do not represent all implantation modes consistent with the present invention, as they are simply examples of apparatus and methods consistent with some aspects of the present invention as detailed in the appended claims.
    [0044] Figure 1A is a flow chart illustrating a method of receiving system information according to a modality, and figure 1B is a scenario diagram illustrating a method of requesting system information according to a modality. The method of receiving system information can be applied to the UE. As shown in figure 1A, the system information request method includes the following steps 110-130.
    [0045] In step 110, a first random access request is
    Petition 870190103419, of 10/14/2019, p. 15/66
    12/34 sent, first random access request which contains at least one pilot code to identify the system information to be requested.
    [0046] In one embodiment, the first random access request is a first MSG 1 message in the random access process.
    [0047] In one embodiment, a time-frequency resource of the random access request can be obtained by means of a first type of system information transmitted by a base station, for example, the time-frequency resource of the access request. random is obtained through the configuration information of a Physical Random Access Channel (PRACH) in a System Information Block 2 (SIB 2). The time-frequency feature of the random access request can be determined using the related technique.
    [0048] In one embodiment, the system information to be requested belongs to a second type of system information, such as the System Information Block 12 (SIB 12).
    [0049] In one embodiment, the pilot code of the system information to be requested is used to identify the system information to be requested, and the pilot code can be a preamble or an orthogonal code in other ways, which is not limited on here.
    [0050] In one mode, one or more pilot codes may be contained in the first random access request.
    [0051] In step 120, a response message corresponding to the first random access request is monitored within a predefined period of time, which response message contains information to respond to the pilot code.
    [0052] In one embodiment, the predefined time period can be a negotiated time interval between the base station and the user equipment. The reply message is returned within the predefined time after MSG 1 is sent. If the
    Petition 870190103419, of 10/14/2019, p. 16/66
    13/34 user equipment receiving the reply message within the predefined period of time, it is considered that no further reply message will be received.
    [0053] In step 130, when the response message is detected, based on a pilot code identifier included in the response message, the system information to be requested is monitored and received within a system information transmission window to be requested that matches the pilot code identifier.
    [0054] In one embodiment, the system information successfully requested can be determined based on the pilot code identifier contained in the response message. For example, if the first random access request contains the pilot code 1 which corresponds to the system information to be requested 1, the pilot code 2 which corresponds to the system information to be requested 2, the pilot code 3 which corresponds to the system information to be requested. system to be requested 3 and if the response message corresponding to the first random access request only includes the pilot code identifiers corresponding to pilot code 1 and pilot code 2, it can be determined that the system information successfully requested is the system information to be requested 1 and the system information to be requested
    2.
    [0055] In one embodiment, the response message corresponding to the first random access request is a Random Access Response (RAR) message.
    [0056] In one embodiment, the UE can determine the transmission window for each of the system information to be requested through the scheduling information contained in the first type of system information transmitted by the base station.
    [0057] In an exemplary scenario, as shown in figure 1B,
    Petition 870190103419, of 10/14/2019, p. 17/66
    14/34 consider the mobile network to be the LTE network and the base station to be an evolved B node (eNB) as an example for illustration. In the scenario shown in figure 1B, eNB 10 and UE 20 are included, where eNB 10 periodically transmits the first type of system information and UE 20 can determine a time-domain resource of the random access request, a system information transmission window to be requested and a pilot system information code to be requested when receiving the first type of system information. UE 20 sends a first random access request containing the pilot code of the system information to be requested in the random access request time domain resource. If it is determined that the system information was successfully requested based on a response message to the first random access request, the UE 20 can monitor the system information to be requested within the successfully requested system information transmission window. . If it is determined that system information is not successfully requested based on the response message to the first random access request, the UE 20 may continue to send a second random access request in the time domain domain of the random access request until that the system information is requested successfully or the time-domain resource is exhausted.
    [0058] In the modality, through steps above 110 to 130, when the UE sends the request for random access containing the pilot code of the system information to be requested to the base station, using the aforementioned technical solutions, the UE can be controlled to monitor the system information to be requested within the successfully requested system information transmission window when the system information is successfully requested, in order to improve the efficiency of sending and receiving system information between the station base and user equipment, thus avoiding a long
    Petition 870190103419, of 10/14/2019, p. 18/66
    15/34 latency for user equipment to obtain system information, which reduces the base station's energy consumption by sending system information and increases the rate of use of spectrum resources.
    [0059] In one embodiment, the method for requesting system information may also include:
    receiving the system information to be requested within the system information transmission window to be requested in response to the determination that at least a portion of the system information that was not successfully requested is null.
    [0060] In one embodiment, the method for requesting system information can also include:
    count the number of requests for system information to be requested; and when the number of requests is greater than a predefined limit, send a network problem notification message to a Radio Resource Control Layer, where the network problem notification message is used to indicate system information to be requested which exceeded the predefined limit of the random access request.
    [0061] In one embodiment, determining at least a portion of the system information that was not successfully requested based on the monitoring result in the predefined time period includes:
    in response to the determination that no response message corresponding to the random access request was received within the predefined period of time, determining that at least a portion of the system information that was not successfully requested is all system information to be requested; and in response to the determination that the response message corresponding to the random access request was received at
    Petition 870190103419, of 10/14/2019, p. 19/66
    16/34 predefined time period, determine that at least a portion of the system information that was not requested successfully is a portion of the system information to be requested, where the portion of the system information to be requested has not been answered by information that is contained in the response message and is used to respond to the pilot code.
    [0062] In particular, regarding how to request system information, please refer to the following examples.
    [0063] Therefore, the above methods provided by the modalities of the present invention are able to improve the efficiency of sending and receiving system information between the base station and the user equipment, thus avoiding a long latency for the user equipment to obtain the system information, which reduces the power consumption of the base station by sending the system information and increases the rate of use of spectrum resources.
    [0064] The technical solutions provided by the examples of the present invention are described in the specific examples below.
    [0065] Figure 2 is a flow chart illustrating another method of requesting system information according to a modality. In this embodiment, using the methods provided above in the examples of the present invention, an example in which the UE requests the system information to be requested by means of the random access request is illustrated. As shown in figure 2, the method includes the following steps.
    [0066] In step 210, a time-frequency resource of the random access request is determined.
    [0067] In step 220, a first random access request is sent through the time-frequency resource of the random access request, in which the first random access request contains a pilot code of system information to be requested.
    Petition 870190103419, of 10/14/2019, p. 20/66
    17/34 [0068] In step 230, it is checked whether there is a response message corresponding to the first random access request within a predefined period of time.
    [0069] In step 240, when the response message is detected, based on a pilot code identifier contained in the response message, the system information that was successfully requested and the system information that was not successfully requested are determined and then step 250 and step 260 are performed. [0070] In one mode, the monitoring result may indicate that no response message was detected and, therefore, that at least a part of the system information that was not successfully requested is all the system information to be requested.
    [0071] In one embodiment, the monitoring result indicates that the response message has been detected, that at least a part of the system information that was not successfully requested is a part of the system information to be requested, in which the part of the system information to be requested is answered by the information that is contained in the response message and used to respond to the pilot code. If the response message contains pilot code information to respond to all system information to be requested, the value of at least a portion of the system information that was not successfully requested will be null. If the response message contains the pilot code information for responding to a portion of the system information to be requested, the value of at least a portion of the system information that was not successfully requested will not be null. [0072] In step 250, if the system information has been successfully requested, the system information to be requested will be monitored and received within a window of transmission of system information successfully requested and then the process will end.
    Petition 870190103419, of 10/14/2019, p. 21/66
    18/34 [0073] In step 260, if the system information has not been successfully requested, a second random access request will be sent, the second random access request which will contain a pilot code to identify the system information that is not was successfully requested.
    [0074] In one embodiment, each system information to be requested can correspond to multiple pilot codes, for example, the system information to be requested 1 can correspond to pilot code 11, pilot code 12 or pilot code 13.
    [0075] In one embodiment, the pilot code of the system information that was not successfully requested, which is contained in the second random access request, may be inconsistent or consistent with the pilot code contained in the first random access request and that corresponds the system information to be requested. For example, when the system information to be requested 1 is not successfully requested, if the pilot code of the system information to be requested 1, which is contained in the first random access request, is the pilot code 11, the code pilot of the system information to be requested 1, which is contained in the second random access request may be pilot code 12 or pilot code 11.
    [0076] In one embodiment, the UE can determine if there is any system information that was not successfully requested, that was requested by the second random access request, based on the response message to the second random access request, and such a process it is the same as the process of determining the part of the system information that was not successfully requested by the first random access request, based on the response message to the first random access request.
    [0077] In one mode, if there is any system information that was not successfully requested after the UE has sent
    Petition 870190103419, of 10/14/2019, p. 22/66
    19/34 the second random access request, the UE may continuously send the second random access request, until all system information has been successfully requested or the time domain feature of the random access request is exhausted, where the pilot code contained in the second random access request sent later is the pilot code of the system information that was not successfully requested.
    [0078] In step 270, the number of requests for system information is counted.
    [0079] In step 280, when the number of requests for a system information to be requested is greater than a predefined limit, it is informed to a Radio Resource Control layer that the number of requests for that system information to be requested requested has reached the maximum limit and that the system information to be requested has reached the maximum limit.
    [0080] In one mode, the predefined request limit can be a system default value, such as 3 times.
    [0081] In the modality, when it determines that the result of the request for the system information was not successfully requested, the UE can be controlled to request repeatedly the system information to be requested through the random access request until it is successful , in order to improve the efficiency of sending and receiving system information between the base station and the user equipment, thus avoiding a long latency for the user equipment to obtain the system information, which reduces the energy consumption of the station basis with the sending of system information and increases the rate of use of spectrum resources.
    [0082] Figure 3 is a flow chart that illustrates a method of sending system information according to a modality. The method of requesting system information can be applied to eNB and the
    Petition 870190103419, of 10/14/2019, p. 23/66
    20/34 modality is illustrated in combination with figure 1B. As shown in figure 3, the system information request method includes the following steps 310-330.
    [0083] In step 310, a random access request containing a pilot code of system information to be requested, sent by the user equipment is received.
    [0084] In step 320, a response message with a predefined format is generated based on a request message.
    [0085] In one embodiment, the predefined format can be a format that only includes one or more subpackage headers, but does not include a package body. For example, the default format does not include information, such as UE's Temporary Cellular Radio Network Identifier (C-RNTI). A pilot code identifier contained in the response message is transmitted via the subpackage header. The method of generating the response message in this predefined format refers to an example shown in figure 4.
