Description

[0001] This invention application is a divisional application of an invention application with an application date of August 11, 2017, application number 201710687311.3, and invention name “A method for sending and obtaining system information and related equipment”. Technical Field

[0002] The present invention relates to the field of communication technology, and in particular to a method for sending and obtaining system information and related equipment. Background Art

[0003] In mobile communication systems, future communication systems, such as the fifth-generation (5G) mobile communication system, support a maximum system bandwidth of 400 MHz, which is much larger than the maximum system bandwidth of 20 MHz supported by the long-term evolution (LTE) system, to support greater system and user throughput.

[0004] On the other hand, the 5G mobile communication system supports dynamic bandwidth allocation, dividing the system bandwidth into multiple bandwidth parts (Bandwidth Part, referred to as BWP) to support narrowband mobile communication terminals, or mobile communication terminals in energy-saving mode only work on part of the system bandwidth. In addition, the 5G mobile communication system also supports multi-beam technology, using beamforming technology to form multiple beams with stronger directivity and narrower lobes to cover mobile communication terminals in the cell.

[0005] In order to reduce signaling overhead, improve wireless resource utilization, and reduce energy consumption of network devices in 5G mobile communication systems, system information is divided into two categories: minimum system information (minimum SI) and on-demand system information (on-demand SI), also known as other system information (Other SI).

[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] In an embodiment of the present invention, a method for sending and a method for obtaining system information can be applied to a system in which a system bandwidth is configured with multiple BWPs, such as eLTE, 4G or 5G systems. Specifically, a method for obtaining system information is applied to a mobile communication terminal in the system, and a method for sending system information is applied to a network device in the system. A mobile communication terminal can communicate with a network device through a network, wherein the mobile communication terminal can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (personal digital assistant, referred to as PDA), a mobile Internet device (Mobile Internet Device, MID) or a wearable device (Wearable Device), etc. The network device can be an evolved base station (Evolutional Node B, referred to as eNB or eNodeB), or a relay station or access point, or a base station in a 5G network (referred to as gNB), or a wireless network controller on the network side, etc., which is not limited here.

[0063] In the embodiment of the present invention, the network device can send system information and / or a physical downlink control channel PDCCH indicating the resource location of the system information through the first target BWP among the multiple BWPs constituting the system bandwidth; correspondingly, the mobile communication device can receive system information and / or a physical downlink control channel PDCCH indicating the resource location of the system information through the first target BWP among the multiple BWPs constituting the system bandwidth. Thus, the sending and obtaining of system information in one or more BWPs constituting the system bandwidth is standardized.

[0064] In the embodiment of the present invention, the mobile communication device can send the system information request message through the second target BWP among the multiple BWPs constituting the system bandwidth; accordingly, the network device can receive the system information request message through the second target BWP among the multiple BWPs constituting the system bandwidth. Thus, the sending and obtaining of the system information request message in one or more BWPs constituting the system bandwidth are standardized.

[0065] See also Figure 1 , Figure 1is a flow chart of a method for sending system information provided by an embodiment of the present invention, such as Figure 1 As shown, the following steps are included:

[0066] Step 101: Receive a system information request message sent by a mobile communication terminal.

[0067] In this step, the system information request message is used to request system information. In practical applications, the mobile communication terminal can request system information through message 1 and message 3 in the random access process, that is, optionally, the system information request message is message 1 or message 3 in the random access process. Specifically, the mobile communication terminal can determine whether to send the request for system information in the form of message 1 or message 3, that is, the system information request message, according to the network device, such as the configuration of the base station or the type of system information requested. Among them, message 1 (Mg.1) is a message for sending a random access preamble in the random access process, and message 3 (Mg.3) is a contention resolution request message in the random access process.

[0068] In a mobile communication system, in order to reduce signaling overhead, improve wireless resource utilization, and reduce energy consumption of network devices, system information is divided into two categories, one is minimum system information (minimum SI), and the other is non-essential system information (On-demand SI), also known as other system information (other SI). For the minimum system information, it can be sent to the mobile communication terminal by the network device in the form of periodic broadcast; and for the non-essential system information, the network device sends it to the mobile communication terminal based on the request of the mobile communication terminal. Therefore, in this step, the system information requested by the system information request message can be non-essential system information, which can be all system information except the minimum system information. However, the specific embodiment of the present invention does not exclude the processing of all system information in a request-based manner.

[0069] In addition, the non-essential system information may include multiple system information blocks (System Information Block, SIB for short). The non-essential system information may be divided into common system information (Common SI) and cell-specific system information (Cell Specific SI) according to the effective range, wherein the Common SI may be shared between at least two cells, and the Common SI of each of the at least two cells needs to be consistent. The Cell specific SI is within the scope of a cell.

[0070] Furthermore, to standardize the reception of system information request messages, the network device may receive system information request messages sent by the mobile communication terminal on a preset BWP, for example, the BWP used by message 1 during random access, or a predefined BWP, or a default BWP, etc.

[0071] Step 102: Send system information and / or a physical downlink control channel PDCCH indicating a resource location of the system information on a first target BWP among a plurality of bandwidth parts BWP constituting the system bandwidth.

[0072] In this step, the system bandwidth may be divided into at least two BWPs, and the first target BWP may be part or all of the at least two BWPs. In addition, the system bandwidth may include only one BWP, that is, it is not divided, and the first target BWP is the system bandwidth. The network device sends the system information and / or the physical downlink control channel PDCCH indicating the resource location of the system information over the full frequency band of the system bandwidth.

[0073] Optionally, if the PDCCH is sent on the first target BWP, the PDCCH carries an identifier and / or bandwidth for indicating the BWP carrying the system information, so that the BWP for transmitting the system information can be specified through the PDCCH.

[0074] In the embodiment of the present invention, the system information and the PDCCH for scheduling the system information may be transmitted through the same BWP or through different BWPs. Specifically, if the system information and the PDCCH for scheduling the system information are transmitted through different BWPs, the transmission of the PDCCH and the system information may be, but is not limited to, a combination of the following situations:

[0075] Case 1: The system information and PDCCH may respectively determine their respective target BWPs according to the embodiment of the present invention, and the specific position of the system information in the target BWP is specified by the PDCCH;

[0076] Case 2: only the system information determines the target BWP according to the embodiment of the present invention, and the specific position of the system information in the target BWP is specified by the PDCCH;

[0077] Case 3: Only the PDCCH determines the target BWP according to the embodiment of the present invention, while the BWP carrying the system information and the specific position of the system information in the BWP are specified by the PDCCH.

[0078] The target BWP for carrying the system information and the PDCCH may be the same or different. In this step, the system information may be minimum system information or non-essential system information.

[0079] Wherein, for the minimum system information, the network device can send the minimum system information to the mobile communication terminal on the first target BWP in the form of periodic broadcasting. In this way, the mobile communication terminal in a connected state, an idle state or an inactive state can receive the minimum system information.

[0080] For non-essential system information, if the mobile communication terminal is in a connected state, the network device can send the non-essential system information to the mobile communication terminal through a dedicated signal (Dedicated signaling) on ​​the first target BWP; if the mobile communication terminal is in an idle state or an inactive state, the network device can send the non-essential system information to the mobile communication terminal through broadcasting on the first target BWP.

[0081] Optionally, the first target BWP is: part or all of the BWPs predefined for sending the system information.

[0082] In this step, the BWP used to send the system information may be predefined, for example, the BWP used to send the system information is directly fixed in the communication protocol between the network device and the mobile communication terminal.

[0083] The predefined BWP for sending the system information may be all BWPs constituting the system bandwidth, or may be a part of the BWPs constituting the system bandwidth.

[0084] Optionally, the first target BWP may also be: a set of BWPs supported by the mobile communication terminal or a part of the set; or a BWP that carries the system information request message.

[0085] In this step, the network device can determine that the first target BWP is a set or part of the BWP supported by the above-mentioned mobile communication terminals based on the BWP capabilities of all mobile communication terminals requesting system information, so as to send system information and / or a physical downlink control channel PDCCH indicating the resource location of the system information on the first target BWP. Each of the above-mentioned mobile communication terminals can receive the system information and / or the physical downlink control channel PDCCH indicating the resource location of the system information sent by the network device on the corresponding BWP in the first target BWP according to its own capabilities.

[0086] In addition, if the mobile communication terminal can send a system information request message on a certain BWP, it indicates that the mobile communication terminal has the ability to support the BWP and can receive information on the BWP. Therefore, the network device can determine that the BWP that sends, i.e., carries the system information request message, is the first target BWP. Specifically, the first target BWP can be the BWP where message 1 or message 3 in the random access process is located.

[0087] Optionally, the first target BWP may also be: part or all of the BWPs designated by a broadcast message or minimum system information for sending the system information.

[0088] In this step, the first target BWP can be set to part or all of the BWPs in the BWP for sending the system information that are pre-specified through a broadcast message or minimum system information. Among them, the broadcast message can be a master information block (Master Information Block, MIB) message sent through a physical broadcast channel (Physical broadcast channel, PBCH for short), but is not limited to this. The method for determining the first target BWP can be applied to scenarios where the network device does not know the BWP capability of the mobile communication terminal that sends the system information request message. Different from the predefined first target BWP, the BWP used to send the system information can be changed through broadcast messages at different time points, thereby improving the flexibility of the first target BWP configuration.

[0089] Optionally, the indication information of the BWP used to send the system information is carried through scheduling information in system information blocks SIB1 and / or SIB2.

[0090] In this step, the indication information of the BWP used to send the system information can be carried by the scheduling information of SIB1 or / and SIB2 of the minimum system information. Specifically, the scheduling information of SIB1 or / and SIB2 can carry the identifier of the BWP used to send the system information. Thus, the network device can determine the first target BWP according to the identifier.

[0091] Optionally, the first target BWP may also be: a BWP corresponding to a current value of the first selection parameter determined according to a first mapping relationship between the first selection parameter and the BWP or the BWP identifier.

[0092] In this step, after obtaining the current value of the first selection parameter, by querying the first mapping relationship, it can be determined that the BWP corresponding to the current value of the first selection parameter is the first target BWP, and system information and / or PDCCH are transmitted on the first target BWP.

[0093] In this step, the first mapping relationship may be predefined or configured by the network device. Specifically, the first mapping relationship may be, but is not limited to, recorded in the form of a function. For example, Y1 represents BWP or BWP identifier, and X1 represents the first selection parameter, then the first mapping relationship may be expressed as Y1=f(X1), where other parameters of the function may be predefined or configured by the network device.

[0094] Optionally, the first selection parameter may include but is not limited to a random access resource identifier that carries the system information request message, a BWP identifier that carries the system information request message, a system information identifier, or a terminal identifier of the mobile communication terminal.

[0095] The BWP identifier may be identified as BWP-index or BWP-ID. The system information identifier is identification information SI_ID of the system information, identification information SIB_ID of the system information block, identification information SIBGroup (SIB group) ID of the group where the system information block belongs, identification information SI Group (SI group) ID of the group where the system information belongs, and / or identification information SI Functionality ID of the function corresponding to the system information.

[0096] Optionally, the terminal identifier may be preset identifier information of the mobile communication terminal or group identifier information of the group to which the mobile communication terminal belongs, or may be part of the bytes of preset identifier information of the mobile communication terminal or group identifier information of the group to which the mobile communication terminal belongs; or, the terminal identifier may be preset information or a variation of preset information; wherein, the preset information includes one of: an international mobile subscriber identity IMSI, a service temporary mobile subscriber identity S-TMSI, a temporary mobile subscriber identity TMSI, a packet service domain temporary mobile subscriber identity P-TMSI, a recovery identifier Resume ID, and a configured identifier Configured ID; the variation of the preset information includes: intercepting part of the bytes in the preset information, for example: UE_ID = IMSI mode N. N is a constant such as 2 to the power of M, which is used to shorten the IMSI.

[0097] Optionally, the first mapping relationship is: a predefined mapping relationship.

[0098] In this step, the first mapping relationship is predefined, for example, the first mapping relationship is pre-fixed in the communication protocol between the network device and the mobile communication terminal.

[0099] Optionally, before sending the system information and / or a physical downlink control channel PDCCH indicating the resource location of the system information on a first target BWP among the multiple bandwidth parts BWP constituting the system bandwidth, the method further includes:

[0100] The first mapping relationship is sent.

[0101] By sending the first mapping relationship to the mobile communication terminal, the mobile communication terminal can determine the first target BWP based on the first mapping relationship, and receive the system information and / or PDCCH on the first target BWP, thereby regulating the reception of the system information. Different from the predefined first mapping relationship, the first mapping relationship used to determine the BWP for sending the system information can be changed by sending messages at different time points, thereby improving the flexibility of the first target BWP configuration.

[0102] Optionally, before sending the system information and / or a physical downlink control channel PDCCH indicating the resource location of the system information on a first target BWP among the multiple bandwidth parts BWP constituting the system bandwidth, the method further includes:

[0103] An indication message is sent, where the indication message is used to indicate the first target BWP, or the indication message is used to indicate the first target BWP and target system information sent on the first target BWP.

[0104] In this step, the network device may directly send an indication message through a broadcast message or other forms of messages. The indication message may be used to indicate the first target BWP, or the indication message is used to indicate the first target BWP and the target system information sent on the first target BWP. The target system information is the system information corresponding to the system information request message sent by the network device according to at least one mobile communication terminal.

[0105] In view of the different indication contents of the indication message, different mobile communication terminals may take different response operations according to the specific contents. The response operations that may be taken by mobile communication terminals with different indication contents are described as follows.

[0106] First, if the indication message is used to indicate the first target BWP, the mobile communication terminal that has sent the system information request message can receive the system information and / or PDCCH on the first target BWP, thereby regulating the reception of the system information;

[0107] Secondly, if the indication message is used to indicate the target system information sent on the first target BWP, the mobile communication terminal that has requested the target system information can receive the target system information on the first target BWP; for the mobile communication terminal that has not requested the target system information but is preparing to send a system information request message requesting the target system information, the content sent on the first target BWP can be determined as the target system information through the indication message. Therefore, the target system information can be directly received on the first target BWP without sending a system information request message requesting the target system information. In this way, not only can the power consumption of the mobile communication terminal be saved, but the collision probability of the random access of the mobile communication terminal sending the system information request message can also be reduced.

[0108] It should be noted that if the network device knows the BWP capability of the mobile communication terminal requesting the system information, the base station can transmit the system information within the BWP capability range supported by the mobile communication terminal in addition to the first target BWP determined by the above scheme. If the network device does not know the mobile communication terminal requesting the corresponding system information, or only knows the BWP capability of some mobile communication terminals requesting the system information, the network device can choose to transmit the system information on the full frequency band or on the BWP determined according to the BWP of the mobile communication terminal. Thereby, the mobile communication terminal can successfully receive the requested system information, and the reliability of receiving the system information is improved.

[0109] The method for sending system information of this embodiment, after receiving a system information request message sent by a mobile communication terminal, sends the system information and / or a physical downlink control channel PDCCH indicating the resource location of the system information through a first target BWP among multiple BWPs constituting the system bandwidth. The sending of system information in one or more BWPs constituting the system bandwidth is standardized.

[0110] See also Figure 2 , Figure 2 is a flow chart of a method for obtaining system information provided by an embodiment of the present invention. Figure 2 As shown, the following steps are included:

[0111] Step 201: Send a system information request message.

[0112] Optionally, the system information request message is message 1 or message 3 in the random access process.

[0113] Furthermore, to standardize the sending of the system information request message, the mobile communication terminal may send the system information request message on a preset BWP, for example, the BWP used in message 1 during the random access process, or a predefined BWP, or a default BWP, etc.

[0114] It should be noted that this embodiment is an implementation method of the mobile communication terminal corresponding to the above embodiment. Therefore, the description of "system information request message and system information" in this embodiment can refer to the relevant description of the above embodiment. In order to avoid repeated description, it will not be repeated here.

[0134] In this step, if the PDCCH is received on the first target BWP, after receiving the PDCCH on the first target BWP, the identifier and / or bandwidth carried by the PDCCH for indicating the BWP carrying the system information is obtained, so that the transmission BWP of the corresponding system information can be specified through the PDCCH, so that the system information is transmitted on the specified BWP.

[0135] Optionally, before sending the system information request message for requesting system information, the method further includes:

[0136] Determining whether the system information has been broadcast;

[0137] If the system information has been broadcasted and the mobile communication terminal can receive the system information on the BWP carrying the system information, the system information is received on the BWP carrying the system information; otherwise, the step of sending a system information request message for requesting the system information is entered.

[0138] In this step, before sending a system information request message for requesting system information, the mobile communication terminal may determine whether the system information requested by the system information request message has been broadcast by a network device based on a request from another mobile communication terminal.

[0139] If the system information to be requested has been broadcast, the mobile communication terminal may determine whether the system information can be received on the BWP carrying the system information based on its own BWP capability after obtaining the BWP carried in the broadcast message for indicating the system information. Specifically, if the mobile communication terminal can receive the system information on the BWP carrying the system information, the system information is received on the BWP carrying the system information; if the mobile communication terminal cannot receive the system information on the BWP carrying the system information, step 201 may be executed.

[0140] If the requested system information has not been broadcast, step 201 may be executed.

[0141] In the above manner, before sending a system information request message for requesting system information, if it is determined that the system information has been broadcasted and the mobile communication terminal can receive the system information on the BWP carrying the system information, the system information is received on the BWP carrying the system information. In this way, not only can the power consumption of the mobile communication terminal be saved, but also the collision probability of the random access of the mobile communication terminal sending the system information request message can be reduced.

[0142] Optionally, the step of determining whether the system information has been broadcast specifically includes:

[0143] By detecting the indication information in the downlink control information DCI corresponding to the physical broadcast channel PBCH, the minimum system information, the paging message, or the PDCCH for scheduling the paging message, it is determined whether the system information has been broadcast on the corresponding BWP.

[0146] See also Figure 3 , Figure 3 is a flowchart of another method for obtaining system information provided by an embodiment of the present invention. Figure 2 The main difference between the method embodiments is that Figure 3 The illustrated embodiment further regulates the BWP that carries the system information request message, specifically: sending the system information request message on the second target BWP among the multiple bandwidth parts BWP constituting the system bandwidth.

[0147] It should be understood that Figure 2 and Figure 3 The embodiments of the present invention may be used independently or in combination. When used in combination, the system information request message is sent on the standard BWP, and the system information is received on the standard BWP.

[0148] like Figure 3 As shown, another method for obtaining system information provided by an embodiment of the present invention includes the following steps:

[0149] Step 301: Send a system information request message on a second target BWP among a plurality of bandwidth parts BWP constituting a system bandwidth.

[0150] In this step, the system bandwidth may be divided into at least two BWPs, and the second target BWP may be part or all of the at least two BWPs. In addition, the system bandwidth may include only one BWP, that is, it is not divided, and the second target BWP is the system bandwidth, and the network device sends the system information request message on the full frequency band of the system bandwidth.

[0151] Optionally, the system information request message is message 1 or message 3 in the random access process.

[0152] Optionally, the second target BWP is: part or all of the BWPs predefined for sending the system information request message.

[0153] In this step, the BWP used to send the system information request message may be predefined, for example, the BWP used to send the system information is directly fixed in the communication protocol between the network device and the mobile communication terminal.

[0154] The predefined BWP for sending the system information may be all BWPs constituting the system bandwidth, or may be a part of the BWPs constituting the system bandwidth.

[0155] Optionally, the second target BWP may also be: part or all of the BWPs specified by a broadcast message or minimum system information for sending a system information request message.

[0156] In this step, the second target BWP can be set to part or all of the BWPs in the BWP for sending the system information request message that is pre-specified through a broadcast message or minimum system information. The broadcast message may be a Master Information Block (MIB) message sent through a physical broadcast channel (PBCH), but is not limited thereto. The BWP for sending the system information request message may be changed through broadcast messages at different time points, thereby improving the flexibility of the first target BWP configuration.

[0157] Optionally, the indication information of the BWP used to send the system information request message is carried through scheduling information in SIB1 and / or SIB2.

[0158] In this step, the indication information of the BWP used to send the system information request message may be carried by the scheduling information of SIB1 or / and SIB2 of the minimum system information.

[0159] Optionally, the second target BWP may also be: a BWP corresponding to the current value of the second selection parameter determined according to a second mapping relationship between the second selection parameter and the BWP or the BWP identifier.

[0160] In this step, after obtaining the current value of the second selection parameter, by querying the second mapping relationship, it can be determined that the BWP corresponding to the current value of the second selection parameter is the second target BWP, and a system information request message is sent on the second BWP.

[0161] In this step, the second mapping relationship can be predefined or configured by the network device. Specifically, the second mapping relationship can be, but is not limited to, recorded in the form of a function. For example, Y2 represents BWP or BWP identifier, and X2 represents the second selection parameter, then the second mapping relationship can be expressed as Y2=f(X2), where other parameters of the function can be predefined or configured by the network device.

[0162] Optionally, the second selection parameter may include but is not limited to a random access resource identifier that carries the system information request message, a BWP identifier that carries the system information request message, a system information identifier, or a terminal identifier of the mobile communication terminal.

Optionally, the system information identifier is the identification information of the system information, the identification information of the system information block, the identification information of the group where the system information belongs, the identification information of the group where the system information block belongs, or the identification information of the function corresponding to the system information.

N is two constants such as 2 to the power of M, which is used to shorten the IMSI.

[0164] Optionally, the second mapping relationship is: a predefined mapping relationship.

[0165] In this step, the second mapping relationship is predefined, for example, the second mapping relationship is pre-fixed in the communication protocol between the network device and the mobile communication terminal.

[0166] Optionally, before sending the system information request message on the second target BWP in the multiple bandwidth parts BWP constituting the system bandwidth, the method further includes:

[0167] Receive the second mapping relationship sent by the network device.

[0168] In this step, the second mapping relationship is sent by the network device. Different from the predefined second mapping relationship, the second mapping relationship used to determine the BWP for sending the system information request message can be changed by sending messages at different time points, thereby improving the flexibility of the second target BWP configuration.

[0169] Optionally, before sending the system information request message on a second target BWP in the multiple bandwidth parts BWP constituting the system bandwidth, the method further includes:

[0170] An indication message sent by a network device is received, where the indication message is used to indicate the second target BWP.

[0171] In this step, the second target BWP sends an indication message through the network device, and the indication message is used to indicate that the second target BWP is determined. The indication information used to determine the BWP for sending the system information request message can be changed by sending messages at different time points, thereby improving the flexibility of the second target BWP configuration.

[0172] Step 302: Receive system information and / or a physical downlink control channel PDCCH indicating a resource location of the system information.

[0173] Further, in order to standardize the reception of system information, the mobile communication terminal may receive the system information and / or the physical downlink control channel PDCCH indicating the resource location of the system information on the first target BWP among the multiple BWPs constituting the system bandwidth. The determination of the first target BWP may be specifically referred to in Figure 1 In order to avoid duplication, the relevant descriptions in the method embodiment will not be repeated here.

[0174] Optionally, before sending the system information request message on a second target BWP in the multiple bandwidth parts BWP constituting the system bandwidth, the method further includes:

[0175] Determining whether the system information has been broadcast;

[0176] If the system information has been broadcast and the mobile communication terminal can receive the system information on the BWP carrying the system information, the BWP is received on the BWP carrying the system information; otherwise, the step of sending a system information request message on the second target BWP among the multiple bandwidth parts BWP constituting the system bandwidth is entered.
