Description

System information sending method, system information obtaining method and related equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for sending and acquiring system information, and a related device.

Background

In mobile communication systems, future communication systems are for example: the maximum 400MHz system bandwidth supported by the fifth Generation (5th-Generation, abbreviated as 5G) mobile communication system is much larger than the maximum 20MHz system bandwidth supported by the Long Term Evolution (LTE) system, so as to support greater system and user throughput.

On the other hand, the 5G mobile communication system supports dynamic Bandwidth allocation, in which the system Bandwidth is divided into a plurality of Bandwidth parts (BWPs) to support a narrowband mobile communication terminal, or a mobile communication terminal in a power saving mode operates only on a Part of the system Bandwidth. In addition, the 5G mobile communication system also supports the multi-beam technology, and forms a plurality of beam coverage cells with stronger directivity and narrower lobes by using the beam forming technology.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the embodiment of the present invention, the sending method and the acquiring method of the system information may be applied to a system in which a system bandwidth is configured with multiple BWPs, for example: eLTE, 4G, 5G or other systems. Specifically, the method for acquiring system information is applied to a mobile communication terminal in the system, and the method for transmitting system information is applied to a network device in the system. The Mobile communication terminal may communicate with the network Device through a network, wherein the Mobile communication terminal may be a Mobile phone, a Tablet personal Computer (Tablet personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device). The network device may be an evolved Node B (eNB or eNodeB), or a relay station or an access point, or a base station in a 5G network (gNB), or a radio network controller on the network side, which is not limited herein.

In the embodiment of the present invention, a network device may send system information and/or a physical downlink control channel PDCCH indicating a resource location of the system information through a first target BWP of a plurality of BWPs constituting a system bandwidth; accordingly, the mobile communication device may receive the system information and/or a physical downlink control channel PDCCH indicating a resource location of the system information through a first target BWP among a plurality of BWPs constituting the system bandwidth. Thereby normalizing transmission and acquisition of system information in one or more BWPs constituting a system bandwidth.

In the embodiment of the present invention, the mobile communication device may transmit the system information request message through a second target BWP among the BWPs constituting the system bandwidth; accordingly, the network device may receive the system information request message through a second target BWP among the plurality of BWPs constituting the system bandwidth. Thereby specifying transmission and acquisition of system information request messages in one or more BWPs constituting a system bandwidth.

Referring to fig. 1, fig. 1 is a flowchart of a method for sending system information according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:

step 101, receiving a system information request message sent by a mobile communication terminal.

In this step, the system information request message is used to request system information. In practical applications, the mobile communication terminal may request system information through the message 1 and the message 3 in the random access procedure, that is, optionally, the system information request message is the message 1 or the message 3 in the random access procedure. Specifically, the mobile communication terminal may be based on network devices, such as: the configuration of the base station or the type of system information requested determines whether the request for system information, i.e., the system information request message, is transmitted in message 1 or message 3. Wherein, the message 1(msg.1) is a message for sending a random access preamble in the random access process, and the message 3(msg.3) is a contention resolution request message in the random access process.

In a mobile communication system, in order to reduce signaling overhead, improve radio 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 unnecessary system information (On-demand SI), which is also called other SI. For the minimum system information, it may be transmitted to the mobile communication terminal by the network device in the form of periodic broadcast; and for unnecessary system information, the network device transmits the system information to the mobile communication terminal upon request of the mobile communication terminal. Therefore, in this step, the system information requested by the system information request message may be unnecessary system information, and may be all system information except minimum system information. But the embodiments of the present invention do not preclude all system information from being processed in a request-based manner.

In addition, the unnecessary System Information may include a plurality of System Information Blocks (SIB). The non-essential system information may be divided into Common system information (Common SI) and Cell Specific SI (Cell Specific SI) according to a valid 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. Cell specific SI is within a Cell.

Further, to specify the reception of the system information request message, the network device may receive, on the preset BWP, the system information request message sent by the mobile communication terminal on the preset BWP, for example: the BWP used by message 1 in the random access procedure is either a predefined BWP or a Default BWP, etc.

Step 102, sending system information and/or a Physical Downlink Control Channel (PDCCH) indicating a resource location of the system information on a first target bandwidth part (BWP) of a plurality of BWPs forming a system bandwidth.

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

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

In the embodiment of the present invention, the system information and the PDCCH scheduling the system information may be transmitted through the same BWP, or may be transmitted through different BWPs. Specifically, if the system information and the PDCCH 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 cases:

in case one, the system information and the PDCCH may respectively determine respective target BWPs according to an embodiment of the present invention, where a specific location of the system information in the target BWPs is specified by the PDCCH;

case two, only the system information determines the target BWP according to the embodiment of the present invention, and the specific location of the system information in the target BWP is specified by the PDCCH;

case three, only the PDCCH determines the target BWP according to the embodiment of the present invention, and the BWP carrying the system information and the specific location of the system information in the BWP are specified by the PDCCH.

The target BWP 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 unnecessary system information.

Wherein for the minimum system information, the network device may transmit the minimum system information to the mobile communication terminal on the first target BWP in the form of periodic broadcasting. Thus, the mobile communication terminal, whether in a connected state or an idle state or an inactive state, can receive minimum system information.

For the unnecessary system information, if the mobile communication terminal is in a connected state, the network device may send the unnecessary 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 may transmit unnecessary system information to the mobile communication terminal in the form of a broadcast on the first target BWP.

Optionally, the first target BWP is: some or all of the predefined BWPs for transmitting the system information.

In this step, BWP for transmitting the system information may be predefined, for example: the BWP for transmitting the system information is directly solidified in a communication protocol of the network device and the mobile communication terminal.

Wherein the predefined BWP for transmitting the system information may be all BWPs constituting the system bandwidth or a part BWP constituting the system bandwidth.

Optionally, the first target BWP may be: a set or part of a set of BWPs supported by the mobile communication terminal; or BWP carrying the system information request message.

In this step, the network device may determine, according to BWP capabilities of all mobile communication terminals requesting system information, that the first target BWP is a set or a part of a set of BWPs supported by the mobile communication terminals, so as to transmit the system information and/or a physical downlink control channel PDCCH indicating a resource location of the system information on the first target BWP, and each of the mobile communication terminals may receive, according to its own capabilities, the system information and/or the physical downlink control channel PDCCH indicating the resource location of the system information transmitted by the network device on a corresponding BWP in the first target BWP.

In addition, if the mobile communication terminal can transmit the system information request message on a certain BWP, indicating that the mobile communication terminal has the capability of supporting the BWP, the mobile communication terminal can receive information on the BWP. Accordingly, the network device may determine that the BWP sent, i.e., carrying the system information request message, is the first target BWP. Specifically, the first target BWP may be the BWP in which message 1 or message 3 is located in the random access procedure.

Optionally, the first target BWP may be: some or all of the BWPs for transmitting the system information designated by the broadcast message or the minimum system information.

In this step, the first target BWP may be set to a part or all of the BWPs previously designated by the broadcast message or the minimum system information for transmitting the 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 determination manner of the first target BWP may be applied to a scenario in which the network device does not know the BWP capability of the mobile communication terminal that transmitted the system information request message. Unlike the predefined first target BWP, the BWP for transmitting the system information may be changed by a broadcast message at different points in time, and thus the flexibility of the configuration of the first target BWP may be improved.

Optionally, the indication information of the BWP for transmitting the system information is carried by scheduling information in a system information block SIB1 and/or SIB 2.

In this step, the indication information of BWP for transmitting the system information may be carried by scheduling information of SIB1 or/and SIB2 of the minimum system information. Specifically, the scheduling information of the SIB1 or/and SIB2 may carry an identifier of the BWP used for transmitting the system information. Thus, the network device may determine the first target BWP based on the identification.

Optionally, the first target BWP may be: and determining the BWP corresponding to the current value of the first selection parameter according to the first mapping relation between the first selection parameter and the BWP or the BWP identification.

In this step, after obtaining the current value of the first selection parameter, the BWP corresponding to the current value of the first selection parameter may be determined as the first target BWP by querying the first mapping relationship, and system information or/and the PDCCH may be transmitted on the first target BWP.

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: denoted BWP or BWP identity with Y1 and X1 denotes a first selection parameter, the first mapping may be denoted as Y1 ═ f (X1), where other parameters of the function may be predefined or configured through the network device.

Alternatively, the first selection parameter may include, but is not limited to, a random access resource identity carrying the system information request message, a BWP identity carrying the system information request message, a system information identity, or a terminal identity of the mobile communication terminal.

Wherein the BWP identification can 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 sibgateway (SIB Group) ID of the Group in which the system information block is located, identification information SI Group ID of the Group in which the system information is located, and/or identification information SI Functionality ID of the function corresponding to the system information.

Optionally, the terminal identifier may be preset identifier information of the mobile communication terminal or group identifier information of a group in which the mobile communication terminal is located, or may be a partial byte of the preset identifier information of the mobile communication terminal or the group identifier information of the group in which the mobile communication terminal is located; or the terminal identification is preset information or deformation of the 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 identity Resume ID and a Configured identity Configured ID; the deformation mode of the preset information comprises the following steps: intercepting part of bytes in the preset information, for example: UE _ ID is IMSI mode N. N is a constant, e.g., 2 to the power of M, for truncating the IMSI.

Optionally, the first mapping relationship is: a predefined mapping relationship.

In this step, the first mapping relationship is predefined, for example: the first mapping relation is solidified in a communication protocol of the network equipment and the mobile communication terminal in advance.

Optionally, before the sending the system information and/or the physical downlink control channel PDCCH indicating the resource location of the system information on the first target BWP in the multiple bandwidth portions BWP constituting the system bandwidth, the method further includes:

and sending the first mapping relation.

By transmitting the first mapping relationship to the mobile communication terminal, the mobile communication terminal may be caused to determine the first target BWP based on the first mapping relationship, and receive the system information or/and the PDCCH on the first target BWP, thereby normalizing the reception of the system information. The first mapping relationship for determining the BWP for transmitting the system information may be changed by transmitting a message at a different time point, differently from the predefined first mapping relationship, and thus the flexibility of the configuration of the first target BWP may be improved.

transmitting an indication message indicating the first target BWP, or indicating the first target BWP and target system information transmitted on the first target BWP.

In this step, the network device may send the indication message directly via a broadcast message or other form of message. Wherein the indication message may be used to indicate the first target BWP, or the indication message may be used to indicate the first target BWP and target system information transmitted on the first target BWP. The target system information is system information corresponding to a system information request message sent by the network equipment according to at least one mobile communication terminal.

Different mobile communication terminals can adopt different coping operations according to specific contents aiming at different indication contents of the indication message, and the following explains the coping operations which can be adopted by the mobile communication terminals with different indication contents.

First, if the indication message indicates the first target BWP, the mobile communication terminal that has sent the system information request message may receive system information or/and a PDCCH on the first target BWP, thereby specifying the reception of the system information;

secondly, if the indication message indicates the target system information transmitted on the first target BWP, the mobile communication terminal requesting the target system information may receive the target system information on the first target BWP; for a mobile communication terminal that does not request the target system information but prepares to transmit a system information request message requesting the target system information, it is possible to determine the contents transmitted on the first target BWP as the target system information through the indication message, and thus, it is possible to directly receive the target system information on the first target BWP without re-transmitting the system information request message requesting the target system information. Thus, the power consumption of the mobile communication terminal can be saved. Meanwhile, the probability of collision of random access of the system information request message sent by the mobile communication terminal can be reduced.

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 may transmit the system information within the range of the BWP capability supported by the mobile communication terminal in addition to the first target BWP determined through the above-described scheme. The network device may choose to transmit the system information over the full band or over the BWP determinable according to the BWP of the mobile communication terminal if the network device does not know the BWP capability of the mobile communication terminal requesting the corresponding system information or knows only the BWP capability of a part of the mobile communication terminals requesting the system information. Therefore, the mobile communication terminal can successfully receive the requested system information, and the reliability of receiving the system information is improved.

In the method for transmitting system information according to this embodiment, after receiving a system information request message transmitted by a mobile communication terminal, a first target BWP of a plurality of BWPs constituting a system bandwidth transmits the system information and/or a physical downlink control channel PDCCH indicating a resource location of the system information. Transmission of system information in one or more BWPs constituting a system bandwidth is specified.

Referring to fig. 2, fig. 2 is a flowchart of a method for acquiring system information according to an embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:

step 201, sending a system information request message.

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

Further, to specify the transmission of the system information request message, the mobile communication terminal may transmit the system information request message on a preset BWP, for example: the BWP used by message 1 in the random access procedure is either a predefined BWP or a default BWP, etc.

It should be noted that this embodiment is implemented as a mobile communication terminal corresponding to the above embodiment, and therefore, for the description of "system information request message and system information" in this embodiment, reference may be made to the relevant description of the above embodiment, and in order to avoid repeated description, details are not repeated herein.

Step 202, receiving system information and/or a physical downlink transmission channel (PDCCH) indicating a resource location of the system information on a first target bandwidth part (BWP) of a plurality of BWPs constituting a system bandwidth.

Optionally, the first target BWP is: a set or part of a set of BWPs supported by the mobile communication terminal; or BWP carrying the system information request message.

Optionally, the first target BWP is: some or all of the BWPs for transmitting the system information designated by the broadcast message or the minimum system information.

Optionally, the indication information of the BWP for sending the system message is carried by scheduling information in SIB1 and/or SIB 2.

Optionally, the first target BWP is: and determining the BWP corresponding to the current value of the first selection parameter according to the first mapping relation between the first selection parameter and the BWP or the BWP identification.

Optionally, the first mapping relationship is a predefined mapping relationship.

Optionally, the first selection parameter is: a random access resource identifier carrying a system information request message, a BWP identifier carrying a 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 is located, the identification information of the group where the system information block is located, or the identification information of the function corresponding to the system information.

Optionally, the terminal identifier is: preset identification information of the mobile communication terminal or group identification information of a group in which the mobile communication terminal is located; or,

the terminal identification is as follows: presetting information or deformation of the presetting 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 identity Resume ID and a Configured identity Configured ID;

the deformation mode of the preset information comprises the following steps: and intercepting partial bytes in the preset information.

Optionally, before the receiving the system information and/or the physical downlink control channel PDCCH indicating the resource location of the system information on the first target BWP in the multiple bandwidth portions BWP constituting the system bandwidth, the method further includes:

and receiving the first mapping relation sent by the network equipment.

receiving an indication message sent by a network device, 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.

Optionally, if the PDCCH is received on the first target BWP, after the receiving the PDCCH on the first target BWP, the method further includes:

and acquiring the identification and/or bandwidth carried by the PDCCH and used for indicating the BWP carrying the system information.

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

Optionally, before sending a system information request message requesting system information, the method further includes:

judging whether the system information is broadcasted or not;

if the system information is broadcasted and the mobile communication terminal can receive on the BWP carrying the system information, receiving the system information on the BWP carrying the system information, otherwise, entering a step of transmitting a system information request message requesting system information.

In this step, before the mobile communication terminal transmits the system information request message requesting the system information, it may be determined whether the system information requested by the system information request message has been broadcast by the network device based on a request of another mobile communication terminal.

If the system information that needs to be requested is broadcast, the mobile communication terminal may obtain the BWP indicating the system information carried in the broadcast message, and determine whether the system information can be received at the BWP carrying the system information according to its own BWP capability. Specifically, if the mobile communication terminal can receive 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 on BWP carrying the system information, step 201 may be performed.

If the system information that needs to be requested is not broadcast, step 201 may be performed.

In this manner, before transmitting a system information request message requesting system information, if it is determined that the system information is broadcast and the mobile communication terminal can receive on the BWP carrying the system information, the system information is received on the BWP carrying the system information. Thus, the power consumption of the mobile communication terminal can be saved. Meanwhile, the probability of collision of random access of the system information request message sent by the mobile communication terminal can be reduced.

Optionally, the step of determining whether the system information is already broadcast specifically includes:

whether the system information is broadcast on the corresponding BWP is judged by detecting the indication information in the physical broadcast channel PBCH, the minimum system information, the paging message or the downlink control information DCI corresponding to the PDCCH for scheduling the paging message.

It should be noted that this embodiment is used as an implementation of the mobile communication terminal corresponding to the embodiment of the method in fig. 1, and therefore, this embodiment only explains steps different from the embodiment of the method in fig. 1, and other implementations of the same steps may refer to the relevant descriptions in the embodiment of the method in fig. 1, and are not repeated herein in order to avoid repeated descriptions.
