Detailed Description

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

Fig. 1 is a schematic flow chart diagram illustrating an information request method in accordance with an embodiment of the present disclosure. The information request method shown in this embodiment may be applied to a terminal, where the terminal includes, but is not limited to, an electronic device such as a mobile phone, a tablet computer, a wearable device, a sensor, and an internet of things device. The terminal may communicate with a base station as a user equipment, and the base station includes but is not limited to a 4G base station, a 5G base station, and a 6G base station. The base station may be a base station in an embodiment to which the subsequent request receiving method is applicable.

As shown in fig. 1, the information requesting method may include the steps of:

in step S101, in response to that the target information required to be acquired satisfies a target condition, a request is sent to a base station to request the base station to broadcast the target information.

In one embodiment, the terminal may determine target information that the terminal needs to acquire from the base station, and then determine whether the target information satisfies a target condition, where the target condition may be a single condition or a composite condition, for example, including multiple sub-conditions.

In one embodiment, the target condition may be that the target information is information that is not always broadcast by the base station.

For example, the base station may carry the target Information in an Information Element IE (Information Element) of the broadcasted Minimum System Information RMSI (Remaining Minimum System Information), but the IE that broadcasts the RMSI at ordinary times does not carry the target Information, and carries the target Information in the IE of the RMSI only after receiving the request.

Therefore, the method and the device are beneficial to ensuring that when the terminal needs the target information, the target information can be acquired by sending a request to the base station.

For example, information broadcast by the base station when the terminal is in a non-connected state (idle state, inactive state), for example, a reference signal used by the terminal in the non-connected state. The terminal in the non-connected state may not continuously receive the information broadcast by the base station, so that the base station may not always broadcast the target information when the terminal is in the non-connected state, but may send scheduling information of the target information, such as time-frequency resource information, to the terminal only after receiving the request, and further, when the terminal is in the non-connected state, the base station may broadcast the target information according to the scheduling information, and accordingly, when the terminal is in the non-connected state, the terminal may receive the target information broadcast by the base station according to the scheduling information.

Accordingly, after receiving the request, the base station can determine that the terminal sending the request supports receiving the information in the non-connection state, so that the information is broadcasted in the non-connection state, and resource waste is avoided.

Optionally, the target condition comprises:

the target information is carried in the information element of the remaining minimum system information.

In an embodiment, the base station may perform broadcasting by using the information element of the remaining minimum system information to carry the target information, but the base station does not carry the target information in the information element of the remaining minimum system information broadcasted each time, and thus the terminal may not obtain the target information when the information element of the remaining minimum system information does not carry the target information.

According to the embodiment of the present disclosure, for the target information carried in the information element of the remaining minimum system information, for example, the scheduling information of the other system information blocks, the base station may not always broadcast, and the terminal may send the request to the base station when the target information needs to be acquired, so that the base station carries the target information in the broadcasted information element of the remaining minimum system information, so that the terminal acquires the target information.

Fig. 2 is a schematic flow chart diagram illustrating another target information request in accordance with an embodiment of the present disclosure. As shown in fig. 2, the method further comprises:

in step S201, in response to receiving the acknowledgement information of the base station for the request, receiving the remaining minimum system information sent by the base station, and acquiring the target information from the information element of the remaining minimum system information.

In some possible embodiments, in response to receiving the acknowledgement information of the base station for the request, the remaining minimum system information sent by the base station is received, and the target information is obtained from an information element of the remaining minimum system information. Namely: the base station first transmits acknowledgement information before transmitting the target information through the RMSI.

Of course, this step is not a necessary step, namely: the base station may transmit the target information directly through the RMSI without transmitting the acknowledgement information. Namely: in one embodiment, after receiving the request, the base station may determine whether to broadcast the target information to the terminal as needed, and in response to determining to broadcast the target information to the terminal, may first send acknowledgement information (e.g., ACK information) to the terminal or not send any information; in response to determining not to broadcast the target information to the terminal, negative information (e.g., NACK information) may be transmitted to the terminal or no information may be transmitted. Namely: it may be determined, depending on the configuration or communication protocol, that when no acknowledgment is received, the target information will or will not be sent via the RMSI by default.

After receiving the confirmation information of the base station for the request, the terminal may determine that the base station is to carry the target information in the information element of the broadcasted remaining minimum system information, and thus may receive the remaining minimum system information sent by the base station and acquire the target information from the received information element of the remaining minimum system information.

Optionally, the method further comprises:

and determining that target information acquisition fails in response to not acquiring the target information from the information elements of the remaining minimum system information.

In an embodiment, after receiving the confirmation information sent by the base station for the request, the terminal may check whether there is target information in the information elements of the remaining minimum system information broadcast by the base station, and if there is target information, it determines that the target information is successfully acquired, and if not, it determines that the target information is failed to be acquired.

Optionally, the target conditions include:

the target information is system information acquired by a broadcast acquisition mode.

In one embodiment, the target information may be system information, such as a system information block SIB-x, which the terminal may acquire by broadcasting, but for the system information, the base station may not broadcast continuously, for example, the system information is carried only in individual broadcast information, in which case, the terminal may need to wait for a long time if it waits for the base station to broadcast the system information, and therefore, the terminal may send the request to the base station when the target information needs to be acquired, so that the base station carries the target information in the next broadcast information, so that the terminal receives the target information as soon as possible.

Optionally, the target condition further comprises:

the scheduling information of the system information is carried in the remaining minimum system information.

In one embodiment, the target condition may further include scheduling information of the system information carried in the remaining minimum system information, in addition to the system information acquired by the broadcast acquisition manner. That is, when the target information is the system information acquired by the broadcast acquisition mode and the scheduling information of the system information is carried in the remaining minimum system information, the terminal sends the request to the base station.

The System Information continuously broadcast by the base station mainly comprises two parts, wherein one part of the content is a main System Information Block (MIB), and the other part of the content is SIB-1 in a System Information Block (System Information Block), wherein SIB-1 can be understood as the remaining minimum System Information, and the other System Information blocks, such as SIB-2, SIB-3, etc., are not continuously broadcast by the base station.

For other system information blocks, when the base station needs broadcasting, the base station can carry the scheduling information of the other system information blocks in the information elements of the remaining minimum system information for transmission. However, when the information element of the remaining minimum system information does not carry the scheduling information of other system information blocks, the terminal cannot acquire the scheduling information of other system information blocks, and cannot receive other system information blocks according to the scheduling information.

In this embodiment, the terminal may send the request to the base station when the target information is system information acquired in a broadcast acquisition manner and scheduling information of the system information is carried in the remaining minimum system information, and for the system information acquired in a broadcast manner, for example, SIB-1, of which the scheduling information is not in the remaining minimum system information, if it is determined that the base station may continuously broadcast, the terminal does not need to send the request, which is beneficial to saving communication resources.

FIG. 3 is a schematic flow chart diagram illustrating yet another target information request in accordance with an embodiment of the present disclosure. As shown in fig. 3, the method further comprises:

in step S301, receiving remaining minimum system information sent by the base station, and acquiring the scheduling information from the remaining minimum system information;

in step S302, in response to acquiring the scheduling information from the remaining minimum system information, the system information is received according to the scheduling information.

In some possible embodiments, in response to receiving the acknowledgement information of the base station for the request, the remaining minimum system information sent by the base station is received, and the scheduling information is obtained from an information element of the remaining minimum system information. Namely: the base station first transmits acknowledgement information before transmitting the scheduling information through the RMSI.

Of course, this step is not a necessary step, namely: the base station may transmit the scheduling information directly through the RMSI without transmitting the acknowledgement information. Namely: in one embodiment, after receiving the request, the base station may determine whether to broadcast the target information to the terminal as needed, may first send acknowledgement information (e.g., ACK information) or no information to the terminal in response to determining to broadcast the target information to the terminal, and may send negative information (e.g., NACK information) or no information to the terminal in response to determining not to broadcast the target information to the terminal. Namely: it may be determined according to a configuration or a communication protocol that when the acknowledgement information is not received, it may be default that the scheduling information will be transmitted or will not be transmitted through the RMSI.

After receiving the confirmation information of the base station for the request, the terminal may determine that the base station is to broadcast the target information, and then may receive the remaining minimum system information sent by the base station first, and obtain the scheduling information from the remaining minimum system information, and after obtaining the scheduling information from the remaining minimum system information, may further receive the system information according to the scheduling information.

Optionally, the target conditions include:

the target information is system information acquired in an on demand mode.

In an embodiment, the target information may be system information, for example, a system information block SIB-y, and the terminal may obtain the system information in an on-demand manner, but for the system information, the base station does not broadcast at ordinary times, but broadcasts the system information after receiving a terminal request.

Optionally, the target condition further comprises:

In one embodiment, the target condition may further include that scheduling information of the system information is carried in the remaining minimum system information, in addition to the system information acquired by the broadcast acquisition manner. That is, when the target information is the system information acquired by the broadcast acquisition mode and the scheduling information of the system information is carried in the remaining minimum system information, the terminal sends the request to the base station.

The system information continuously broadcasted by the base station mainly comprises two parts of contents, wherein one part of contents is a main system information block, and the other part of contents is SIB-1 in the system information block, wherein SIB-1 can be understood as the remaining minimum system information, and the other system information blocks, such as SIB-2, SIB-3, etc., are not continuously broadcasted by the base station.

The terminal in this embodiment may send the request to the base station when the target information is system information acquired in a broadcast acquisition manner and scheduling information of the system information is carried in the remaining minimum system information, and for system information acquired in an on-demand manner where the scheduling information is not in the remaining minimum system information, if it is determined that the base station may continuously broadcast, the request does not need to be sent, which is beneficial to saving communication resources.

Fig. 4 is a schematic flow chart diagram illustrating yet another target information request in accordance with an embodiment of the present disclosure. As shown in fig. 4, the method further comprises:

in step S401, receiving the remaining minimum system information sent by the base station, and acquiring the scheduling information from the remaining minimum system information;

in step S402, in response to acquiring the scheduling information from the remaining minimum system information, the system information is received according to the scheduling information.

In an embodiment, after receiving the confirmation information sent by the base station for the request, the terminal may check whether the scheduling information of the target information exists in the remaining minimum system information broadcast by the base station, if not, it is determined that the target information acquisition fails, if so, it is determined that the target information acquisition succeeds, and further, the target information is acquired according to the scheduling information.

Optionally, the target condition comprises:

the target information is a reference signal used in a non-connected state.

In one embodiment, the target Information may be a Reference Signal, such as a TRS (Tracking Reference Signal), a CSI-RS (Channel State Information-Reference Signal), a CRS (Cell Reference Signal), or the like.

For example, in a scenario where the terminal receives the paging signaling, the terminal wakes up at a paging occasion for receiving the paging signaling and basically stays in a sleep state at other times for power saving, but needs to perform synchronization in order to be able to perform synchronization so as to receive the paging signaling at the paging occasion.

In the related art, the terminal performs synchronization according to the synchronization signal block SSB, but the distance between the synchronization signal block and the paging occasion is long, and the terminal needs to wake up for a long time between the paging occasions and keep waking up to the paging occasion in order to receive the synchronization signal block, which results in high power consumption. However, the distance between the reference signal and the paging occasion in this embodiment is relatively short, and is shorter than the distance between the synchronization signal block and the paging occasion, so that the terminal can wake up in a shorter time between the paging occasions and keep waking up to the paging occasion, and power consumption is low.

Fig. 5 is a schematic flow chart diagram illustrating yet another target information request in accordance with an embodiment of the present disclosure. As shown in fig. 5, the method further comprises:

in step S501, scheduling information of the reference signal is received, and the reference signal is received according to the scheduling information in a non-connected state.

In some possible embodiments, the scheduling information sent by the base station is received in response to receiving acknowledgement information for the request by the base station. Namely: the base station first transmits acknowledgement information before transmitting the scheduling information.

Of course, this step is not a necessary step, namely: the base station may transmit the scheduling information directly without transmitting the acknowledgement information. Namely: in one embodiment, after receiving the request, the base station may determine whether to broadcast the target information to the terminal as needed, may first send acknowledgement information (e.g., ACK information) or no information to the terminal in response to determining to broadcast the target information to the terminal, and may send negative information (e.g., NACK information) or no information to the terminal in response to determining not to broadcast the target information to the terminal. Namely: it may be determined, based on configuration or communication protocol, that when no acknowledgement is received, the scheduling information may be sent or not sent by default.

After receiving the confirmation information of the base station for the request, the terminal may determine that the base station is to broadcast the target information, and then may receive the scheduling information of the reference signal sent by the base station first, where the action may be performed in a connected state or a non-connected state, and specifically may be selected as needed, and after receiving the scheduling information, may further receive the reference signal in the non-connected state according to the scheduling information.

Fig. 6 is a schematic flow chart diagram illustrating yet another target information request in accordance with an embodiment of the present disclosure. As shown in fig. 6, the sending the request to the base station includes:

in step S601, a random access message is sent to the base station through a preset resource, where the random access message is used to request the target information.

In an embodiment, the terminal may have a resource pre-agreed with the base station, that is, the pre-agreed resource may be pre-agreed in a communication protocol, or may be broadcast by the base station and agreed with the terminal, or may be sent by the base station to the terminal through an RRC (radio resource control) signaling and agreed with the terminal.

The preset resource may be a resource of a Physical Random Access Channel (PRACH), and for a Random Access message sent by the terminal on the preset resource, the base station may determine that it is equivalent to the request, so that the terminal sends the Random Access message to the base station on the preset resource, which is equivalent to sending the request, thereby implementing multiplexing of the Random Access message.

It should be noted that, for different target conditions in the foregoing embodiments, the preset resources may be different, so that the base station may determine the target information requested by the terminal according to the different preset resources.

For example, the target condition includes that the target information is carried in the information element of the remaining minimum system information, the preset resource may be a first resource, and when receiving a random access message sent by the terminal at the first resource, the base station may determine that the target information carried in the information element of the remaining minimum system information is requested by the terminal.

For example, the target condition includes that the target information is system information acquired in a broadcast acquisition manner, the preset resource may be a second resource, and when receiving a random access message sent by the terminal in the second resource, the base station may determine that the system information acquired in the broadcast acquisition manner is requested by the terminal.

In this case, when receiving the random access message sent by the terminal in the second resource, the base station may further determine that scheduling information of the system information acquired in the broadcast acquisition manner needs to be sent to the terminal. That is, when receiving the random access message sent by the terminal in the second resource, the base station may determine the scheduling information of the system information that the terminal requests to acquire in the broadcast acquisition manner, and may also determine the system information that the terminal requests to acquire in the broadcast acquisition manner and that corresponds to the scheduling information, so as to send the scheduling information and the system information that the scheduling information corresponds to and that is acquired in the broadcast acquisition manner. Then, the terminal sends the random access message once on the second resource, so that the base station can send the scheduling information and the system information corresponding to the scheduling information and acquired in a broadcast acquisition manner, which is beneficial to reducing the occupation of communication resources.

In addition, in this case, the base station may determine that the terminal requests the scheduling information only when receiving the random access message sent by the terminal on the second resource, and determine that the terminal requests the system information acquired in the broadcast acquisition manner corresponding to the scheduling information when receiving the random access message sent by the terminal on the second resource again. The terminal can respectively send the random access message twice, so that the base station respectively sends the scheduling information and the system information which is obtained in a broadcast obtaining mode and corresponds to the scheduling information, and the flexibility of sending the scheduling information and the system information is favorably improved.

For example, the target condition includes that the target information is system information acquired in an on-demand manner, the preset resource may be a third resource, and the base station may determine that the system information acquired in the on-demand manner is requested by the terminal when receiving a random access message sent by the terminal in the third resource.

In this case, when receiving the random access message sent by the terminal on the third resource, the base station may further determine that scheduling information of the system information acquired in the on-demand acquisition manner needs to be sent to the terminal. That is, when receiving the random access message sent by the terminal in the second resource, the base station may determine the scheduling information of the system information requested to be acquired by the terminal in the on-demand acquisition manner, and may also determine the system information requested to be acquired by the terminal in the on-demand acquisition manner and corresponding to the scheduling information, so as to send the scheduling information and the system information corresponding to the scheduling information and acquired in the on-demand acquisition manner. Then, the terminal sends the random access message once on the second resource, so that the base station can send the scheduling information and the system information corresponding to the scheduling information and acquired in an on-demand manner, which is beneficial to reducing the occupation of communication resources.

In addition, in this case, the base station may determine that the terminal requests the scheduling information only when receiving the random access message sent by the terminal on the second resource, and determine that the terminal requests the system information acquired in the on-demand acquisition manner corresponding to the scheduling information when receiving the random access message sent by the terminal on the second resource again. The terminal can respectively send the random access message twice, so that the base station respectively sends the scheduling information and the system information corresponding to the scheduling information and acquired in an on-demand acquisition mode, and the flexibility of sending the scheduling information and the system information is favorably improved.

Optionally, the method further comprises:

and in response to determining that the target information acquisition fails, determining whether to send the request to the base station again according to the implementation of the terminal.

In the foregoing embodiment, if it is determined that the target information acquisition fails, the terminal may determine whether to send the request to the base station again according to its own implementation, for example, if the terminal itself implements that the request needs to be sent again, and the number of times of sending again is a preset number of times, the terminal may send the request to the base station again until it is determined that the target information acquisition succeeds, or the number of times of sending reaches the preset number of times.

For example, the target condition includes that the target information is a reference signal used in a non-connected state, the preset resource may be a fourth resource, and the base station may determine that the reference signal used in the non-connected state is requested by the terminal when receiving a random access message sent by the terminal in the fourth resource.

Optionally, the random access message includes at least one of:

a first message MSG1 in the random access procedure, and a third message MSG3 in the random access procedure.

FIG. 7 is a schematic flow chart diagram illustrating yet another target information request in accordance with an embodiment of the present disclosure. As shown in fig. 7, the sending the random access message to the base station through the preset resource includes:

in step S701, in response to that there is no first preset resource for sending the first message to the base station, the third message is sent to the base station.

In an embodiment, if there is no first preset resource for sending the first message to the base station, the third message may be sent to the base station, so that the third message in the random access process is used as the request, and it is ensured that the request can be sent to the base station.

The third message may carry information about the requested content, so that the base station may determine the content requested by the third message, for example, the system information carried in the information element of the remaining minimum system information, the system information acquired in a broadcast acquisition manner, the system information acquired in an on-demand manner, a reference signal used in a non-connected state, and the like.

Fig. 8 is a schematic flow chart diagram illustrating a request receiving method according to an embodiment of the present disclosure. The request receiving method shown in this embodiment may be applied to a base station, where the base station includes but is not limited to a 4G base station, a 5G base station, and a 6G base station, and the base station may communicate with a terminal as user equipment, and the terminal includes but is not limited to an electronic device such as a mobile phone, a tablet computer, a wearable device, a sensor, and an internet of things device. The terminal may be a terminal in an embodiment to which the above information request method is applied.

As shown in fig. 8, the request receiving method may include the steps of:

in step S801, receiving a request sent by a user equipment, where the request is used for requesting broadcast target information;

In one embodiment, the terminal may determine target information that needs to be acquired from the base station, and then determine whether the target information satisfies a target condition, where the target condition may be a single condition or a composite condition, for example, including multiple sub-conditions.

For example, the base station may carry the target information in an information element IE of the broadcasted minimum system information RMSI, but the IE of the broadcasted RMSI does not carry the target information at ordinary times, and the target information is carried in the IE of the RMSI only after the request is received.

Accordingly, when the terminal needs the target information, the terminal can obtain the target information by sending a request to the base station.

Accordingly, after receiving the request, the base station can determine that the terminal sending the request supports receiving the information in the non-connection state, so that the information is broadcasted in the non-connection state, and the waste of resources is avoided.

Optionally, the target conditions include:

In an embodiment, the base station may broadcast the target information carried by the information element of the remaining minimum system information, but the base station does not carry the target information in the information element of the remaining minimum system information broadcasted each time, and then the terminal may not obtain the target information when the information element of the remaining minimum system information does not carry the target information.

Fig. 9 is a schematic flow chart diagram illustrating another request receiving method according to an embodiment of the present disclosure. As shown in fig. 9, the method further comprises:

in step S901, the remaining minimum system information is sent, and the information element of the remaining minimum system information at least includes the target information.

In an embodiment, after receiving the request, the base station may determine whether to broadcast the target information to the terminal as needed, and in response to determining to broadcast the target information to the terminal, may first send an acknowledgement ACK to the terminal; in response to determining not to broadcast the target information to the terminal, a negative information NACK may be transmitted to the terminal.

The base station may broadcast the remaining minimum system information under the condition that it is determined that the target information is broadcast to the terminal, where the information element of the remaining minimum system information at least includes the target information, and after the terminal receives the confirmation information of the base station for the request, it may be determined that the base station is to carry the target information in the information element of the remaining minimum system information that is broadcast, so that the remaining minimum system information sent by the base station may be received, and the target information may be acquired from the received information element of the remaining minimum system information.

Optionally, the target condition comprises:

the target information is system information acquired in a broadcast acquisition mode or system information acquired in an on demand mode.

In an embodiment, the target information may be system information, for example, a system information block SIB-y, and the terminal may acquire the system information in an on-demand manner, but for the system information, the base station does not broadcast at ordinary times, but broadcasts the system information after receiving a terminal request, in this case, the terminal may send the request to the base station when the terminal needs to acquire the target information, so that the base station carries the target information in the next broadcast information to ensure that the terminal receives the target information.

in step S1101, scheduling information of the reference signal is transmitted, and the reference signal is broadcasted according to the scheduling information when the terminal is in a non-connected state.

In one embodiment, after receiving the request, the base station may determine whether to broadcast the target information to the terminal as needed, may first send acknowledgement information ACK to the terminal in response to determining to broadcast the target information to the terminal, and may send negative information NACK to the terminal in response to determining not to broadcast the target information to the terminal.

The base station may send scheduling information of the reference signal to the terminal after determining that the reference signal information is broadcast to the terminal, and broadcast the reference signal according to the scheduling information when the terminal is in the non-connected state, and the terminal may determine that the base station is to broadcast the target information after receiving the confirmation information of the base station for the request, and then may receive the scheduling information of the reference signal sent by the base station first, and the action may be performed in the connected state or the non-connected state, and may specifically perform selection as needed, and after receiving the scheduling information, may further receive the reference signal according to the scheduling information in the non-connected state.

Optionally, the receiving the request sent by the user equipment includes:

and receiving a random access message sent by the terminal at a preset resource, wherein the random access message is used for requesting the target information.

In an embodiment, the terminal may pre-agree with the base station on resources, that is, the pre-set resources may be pre-specified in a communication protocol, may also be broadcast by the base station and agreed with the terminal, and may also be sent by the base station to the terminal an RRC (radio resource control) signaling and agreed with the terminal.

The preset resource can be a resource of a physical random access channel, and for a random access message sent by the terminal on the preset resource, the base station can determine that the random access message is equivalent to the request, so that the terminal sends the random access message to the base station on the preset resource, which is equivalent to sending the request, and multiplexing of the random access message is realized.

It should be noted that, for different target conditions in the foregoing embodiment, the preset resources may be different, so that the base station may determine the target information requested by the terminal according to the different preset resources.

For example, the target condition includes that the target information is carried in the information element of the remaining minimum system information, the preset resource may be a first resource, and the base station may determine that the target information carried in the information element of the remaining minimum system information is requested by the terminal when receiving a random access message sent by the terminal at the first resource.

For example, the target condition includes that the target information is system information acquired by a broadcast acquisition manner, the preset resource may be a second resource, and the base station may determine that the system information acquired by the broadcast acquisition manner is requested by the terminal when receiving a random access message sent by the terminal in the second resource.

In this case, when receiving the random access message sent by the terminal in the second resource, the base station may further determine that scheduling information of the system information acquired in the broadcast acquisition manner needs to be sent to the terminal. That is, when receiving the random access message sent by the terminal in the second resource, the base station may determine the scheduling information of the system information that the terminal requests to acquire in the broadcast acquisition manner, and may also determine the system information that the terminal requests to acquire in the broadcast acquisition manner and that corresponds to the scheduling information, so as to send the scheduling information and the system information that the scheduling information corresponds to and that is acquired in the broadcast acquisition manner. Then, the terminal sends the random access message once on the second resource, which enables the base station to send the scheduling information and the system information corresponding to the scheduling information and acquired in a broadcast acquisition manner, and is beneficial to reducing the occupation of communication resources.

In this case, the base station may determine that the terminal requests the scheduling information only when receiving the random access message transmitted by the terminal on the second resource, and determine that the terminal requests the system information acquired in the broadcast acquisition manner corresponding to the scheduling information when receiving the random access message transmitted by the terminal on the second resource again. The terminal can respectively send the random access message twice, so that the base station respectively sends the scheduling information and the system information corresponding to the scheduling information and acquired in a broadcast acquisition mode, and the flexibility of sending the scheduling information and the system information is favorably improved.

In addition, in this case, the base station may determine that the terminal requests the scheduling information only when receiving the random access message sent by the terminal on the second resource, and determine that the terminal requests the system information acquired in the on-demand acquisition manner corresponding to the scheduling information only when receiving the random access message sent by the terminal on the second resource again. The terminal can respectively send the random access message twice, so that the base station respectively sends the scheduling information and the system information corresponding to the scheduling information and acquired in an on-demand acquisition mode, and the flexibility of sending the scheduling information and the system information is favorably improved.

Optionally, the random access message includes at least one of:

the first message in the random access process, and the third message in the random access process.

In any of the above embodiments, the base station may further perform the following steps: and sending the confirmation information.

Of course, this step is not a necessary step, namely: the base station may directly transmit the scheduling information or the target information without transmitting the acknowledgement information. Namely: in one embodiment, after receiving the request, the base station may determine whether to broadcast the scheduling information or the target information to the terminal as needed; in response to determining to broadcast the scheduling information or the target information to the terminal, an acknowledgement (e.g., ACK information) or no information may be transmitted to the terminal; in response to determining not to broadcast the target information to the terminal, negative information (e.g., NACK information) or no information may be transmitted to the terminal.
