Description

System message transmission method, device and system

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, and a system for transmitting a system message.

Background

In a conventional communication System, such as a Long Term Evolution (LTE) System, most of the System messages, such as a Master Information Block (MIB) message and a System Information Block (System Information Blocks) message transmitted in a broadcast channel, are periodically transmitted.

In the conventional LTE system, in order to reduce resource occupation of periodic messages as much as possible, the system messages are generally divided into different parts for transmission, specifically, a large number of parts of system messages are placed in a channel or system resource that does not need to be transmitted periodically, and a small number of parts of system messages are placed on a periodic transmission channel such as a broadcast channel for transmission. A part of the content of the system message that is more important is defined as a minimum message, the priority of the minimum message is higher, and the existing LTE system divides the minimum message into: the base station carries a part of minimum messages in the system messages in a Broadcast Channel for sending, the part of minimum messages sent through the Broadcast Channel does not include parameters required by the terminal device for uplink transmission, the base station needs to notify the terminal device in a Physical Broadcast Channel (PBCH) of resource positions at which to acquire the remaining minimum messages, that is, the parameters required by the terminal device for uplink transmission need to be transmitted in the remaining minimum messages, and the terminal device can perform uplink transmission only after receiving the remaining minimum messages, so that delay and overhead of uplink transmission by the terminal device are relatively large. In order to improve the utilization rate of resources, a New generation mobile communication system (New Radio, abbreviated as NR) also requires that the resources occupied by system messages periodically transmitted in the system are as less as possible, and therefore, it has been proposed to apply the partition method in the existing LTE system to the New generation mobile communication system to transmit the system messages.

However, if the segmentation method in the existing LTE system is applied to a new generation mobile communication system, the terminal device needs to perform uplink transmission after receiving the remaining minimum message, which causes a delay and a high overhead for the terminal device to perform uplink transmission; in addition, because the division method in the LTE system is relatively fixed, the method is only applicable to specific application scenarios, that is, the method has poor practicability and flexibility in sending system messages.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.

Before describing the method for transmitting system messages provided in the embodiment of the present invention, a manner of splitting a minimum message in system messages sent in an existing LTE system is briefly described, as shown in fig. 1, which is a flowchart for sending system messages in an existing LTE system, a system message transmitted in fig. 1 is a minimum message with a higher priority, and the flow shown in fig. 1 includes the following steps, i.e., step 1 to step 4:

step 1, a base station sends a part of minimum information through a broadcast channel, wherein the part of minimum information does not comprise uplink transmission parameters; accordingly, the terminal device receives the part of the minimum message;

step 2, the base station informs the terminal equipment of receiving the resource of the residual minimum message in the PBCH;

step 3, the terminal equipment receives the residual minimum message on the resource notified by the base station, and the residual minimum message comprises the uplink transmission parameter;

and 4, the terminal equipment sends uplink data according to the uplink transmission parameters in the received residual minimum message.

As can be seen from the flow shown in fig. 1, the terminal device needs to acquire the uplink transmission parameter after receiving the remaining minimum message, and then sends the uplink signal according to the uplink transmission parameter, so that both the delay and the overhead of the uplink transmission performed by the terminal device are relatively large.

The technical solution of the present invention is described in detail below with specific embodiments, where the entities interactively executed in the following embodiments of the present invention include a base station and a terminal device, where the base station may include: a Base Station (Base Station, abbreviated as BS), an evolved Node B (evolved Node B, abbreviated as eNB), and a terminal device, for example, a User Equipment (User Equipment, abbreviated as UE), may include: personal Computers (PC), smart phones, tablet PCs, personal Digital Assistants (PDA), and the like. The following specific embodiments of the present invention may be combined, and the same or similar concepts or processes may not be described in detail in some embodiments.

First embodiment

Fig. 2 is a flowchart of a method for transmitting a system message according to a first embodiment of the present invention. The method for transmitting the system message provided by the embodiment is suitable for the case of transmitting the system message in a new generation mobile communication system, and the method can be executed by a transmission device of the system message, the transmission device of the system message is realized by combining hardware and software, and the device can be integrated in a processor of a base station for being called and used by the processor. As shown in fig. 2, the method of this embodiment may include:

S110, the base station sends a first system message to the terminal equipment through a broadcast channel, wherein the first system message comprises a receiving parameter and indicating information of a second system message, and the indicating information is used for indicating whether the first system message comprises an uplink transmission parameter.

In the embodiment of the present invention, a manner is provided in which a base station sends a system message to a terminal device in its coverage area, where the coverage area of the base station has multiple cells, and each cell has multiple terminal devices. In this embodiment of the present invention, the system messages to be sent by the base station at least include the first system message and the second system message, where the first system message and the second system message are messages with higher priority in the system messages, and it can be understood that the first system message is a part of the minimum messages in fig. 1, and the second system message is the remaining minimum messages in fig. 1. The uplink transmission parameters in the embodiment of the present invention include, for example, resource configuration parameters such as resources, power, and code channels required for uplink transmission by the terminal device, for example, the uplink transmission is an uplink random access signal, and the uplink transmission parameters may include parameters such as a preamble index, time-frequency resources of the random access signal, and power configuration.

In the embodiment of the present invention, the base station may send the first system message and the second system message in several times, and send the first system message through the broadcast channel, where the first system message includes a receiving parameter of the second system message, and the receiving parameter is used to instruct the base station to send the second system message on which resources subsequently, and at the terminal device side, after receiving the first system message, the base station may obtain the receiving parameter of the second system message, and learn which resources to receive the second system message according to the receiving parameter.

In the existing LTE system, since the first transmitted minimum message does not include the uplink transmission parameter, the terminal device can transmit the uplink signal after receiving the remaining minimum message (i.e., the second system message). In contrast, the first system message in the embodiment of the present invention further includes indication information, and when the indication information indicates that the first system message includes an uplink transmission parameter, the terminal device may transmit an uplink signal after receiving the first system message, so that delay and overhead of uplink transmission performed by the terminal device are reduced; when the indication information indicates that the first system message does not include the uplink transmission parameter, the terminal needs to transmit the uplink transmission parameter at the base station before the terminal can perform uplink transmission.

And S120, the base station sends the second system message to the terminal equipment according to the receiving parameter of the second system message.

In the embodiment of the present invention, the base station may carry the receiving parameter of the second system message in the first system message, so that both the base station and the terminal device can know on which resources the second system message should be sent, that is, the receiving parameter of the second system message is used to indicate the resource location where the second system message is sent. For example, if the indication information indicates that the first system message includes the uplink transmission parameter, the first system message further includes the uplink transmission parameter, and the terminal device may perform uplink transmission according to the uplink transmission parameter after receiving the first system message; for another example, if the indication information indicates that the first system message does not include the uplink transmission parameter, the uplink transmission parameter may be carried in the second system message and sent, and the terminal device may perform uplink transmission after receiving the second system message; in both cases, the time for the base station to send the second system message is different from the content in the second system message.

In practical applications, the first system message and the second system message may both include uplink transmission parameters, and at this time, the uplink transmission parameters in the first system message are a subset of the uplink transmission parameter set in the second system message.

It should be noted that, for example, the receiving parameter of the second system message included in the first system message in the embodiment of the present invention may be a resource location of a control part or a control part and a data part of the second system message, where the receiving parameter may describe all resource locations of the second system message, or may describe a partial resource location of the second system message, and the non-described partial resource location may be predefined, or may be obtained by the terminal device through blind detection. For example, the system message sent on the time domain resource and the frequency domain resource can calculate and obtain the complete resource location for sending the system message only by describing part of the resource location, so that in many application scenarios, the receiving parameter only describes part of the resource location of the second system message, and the base station and the terminal device can both know the specific resource location for sending the second system message, that is, the base station and the terminal device can send and receive the second system message at the same resource location. The second system message may be in various forms, and may be information in SIB like LTE, or a system message transmitted in a data shared channel, or a system message transmitted in a second PBCH other than PBCH.

In the method for transmitting system messages provided in the embodiments of the present invention, a base station sends a first system message to a terminal device through a broadcast channel, where the first system message includes a receiving parameter and indication information of a second system message, and the indication information is used to indicate whether the first system message includes an uplink transmission parameter, and then the base station may send the second system message to the terminal device according to the receiving parameter of the second system message; in the method provided by this embodiment, the system message is divided into at least two parts, and the content carried in the first system message is reasonably designed, and the second system message is sent in a manner suitable for the current application scenario, so that the problems that when the division manner in the existing LTE system is applied to a new generation mobile communication system, the terminal device needs to perform uplink transmission after receiving the remaining minimum message, and the delay and the overhead of the terminal device in uplink transmission are large are solved; in addition, the problem that the practicability and flexibility of system message sending are poor due to the fact that the division mode in the LTE system is fixed is solved.

Optionally, in this embodiment of the present invention, it is stated that the indication information may indicate different contents, and if the indication information is used to indicate that the first system message does not include the uplink parameter, it implicitly implies that the terminal needs to receive the second system message first and then may perform uplink transmission; if the indication information is used to indicate that the first system message includes the uplink transmission parameter, the indication information may also be extended to indicate which uplink transmission parameter is included in the first system message, that is, the indication information may also be used to indicate different uplink transmission parameter configurations. For example, 01, 10, and 11 of 2 bits may be used to respectively represent the configuration of three different uplink configuration parameters.

Optionally, fig. 3 is a flowchart of another method for transmitting a system message according to the first embodiment of the present invention. It has been described above that when the indication information is used to indicate that the first system message includes the uplink transmission parameter, the first system message further includes the uplink transmission parameter, this embodiment may further include, before S120:

s111, the base station receives an uplink signal sent by the first terminal device according to the uplink transmission parameter;

the implementation manner of S120 in this embodiment is: and the base station sends the second system message to the first terminal equipment on the basic time domain resource unit carrying the second system message according to the receiving parameter of the second system message.

After S111, the method provided in this embodiment may further include:

s112, the base station determines the resource for sending the second system message according to the resource of the uplink signal; the resources of the second system message include one or more of antenna ports and beam indices.

As shown in fig. 4, which is a schematic diagram of transmission of a system message in the method for transmitting a system message provided in the embodiment shown in fig. 3, it can be seen from fig. 4 that, in the manner of transmitting a system message provided in this embodiment, a base station carries parameters required for uplink transmission, which are sent in the remaining minimum message in the flow shown in fig. 1, in the minimum message in a broadcast channel, and sends the parameters, that is, uplink transmission parameters are carried in a first system message, and after receiving the first system message, a terminal device may attempt uplink transmission, which is most likely to be transmission of a random access signal. In the case of multi-beam transmission and reception, the uplink transmission is, for example, transmission of a random access signal, and the uplink transmission and the downlink beam have a mapping relationship, so that the base station can determine, by receiving the uplink signal, a downlink beam having a mapping relationship with the uplink signal, that is, determine which beam is an appropriate downlink beam, so as to use the appropriate downlink beam when transmitting the second system message, and when the appropriate downlink beam is selected, the second system message can be transmitted and received only using the determined downlink beam; optionally, the second system message may be sent by using the determined downlink beam, or may be sent and received by using a part of the downlink beam adjacent to the determined downlink beam, so as to improve the probability and stability of beam reception, accordingly, the terminal device may receive the second system message only on the determined downlink beam or a peripheral part of the downlink beam, the receiving parameter of the second system message is also sent in the first system message in the broadcast channel, and after receiving the second system message, the terminal device may send another uplink signal according to the uplink transmission parameter in the second system message. Because the second system message can specify a proper downlink beam through the mapping relationship, multi-beam transmission is not required to be adopted in resource arrangement, and the second system message can be transmitted in a normal data packaging manner in resource use, that is, the second system message can be transmitted by using a basic time domain resource unit containing a control signal and a data signal, wherein the length of the basic time domain unit is greater than or equal to 7 symbols; optionally, the basic time domain resource unit in the embodiment of the present invention may also be an independent transmission block, where the length of the basic time domain resource unit is less than 7 symbols, and the symbols described in the embodiment of the present invention are all Orthogonal Frequency Division Multiplexing (OFDM) symbols.

Optionally, fig. 5 is a flowchart of a method for transmitting a system message according to a first embodiment of the present invention. It has been described above that when the indication information is used to indicate that the first system message does not include the uplink transmission parameter, the manner of sending the second system message by the base station is different from the embodiment shown in fig. 3, that is, the implementation manner of S120 in this embodiment may be: the base station sends a second system message to the terminal equipment on N basic time domain resource units bearing the second system message according to the receiving parameter of the second system message; wherein N is a positive integer greater than 1.

As shown in fig. 6, for a system message transmission method provided in the embodiment shown in fig. 5, as can be seen from fig. 6, in the system message transmission method provided in this embodiment, the indication information in the first system message sent by the base station is used to indicate that the first system message does not include an uplink transmission parameter, and the difference from the transmission diagram shown in fig. 4 is that whether the terminal device can send an uplink signal according to the uplink transmission parameter before receiving the second system message, and whether the base station can determine a downlink beam for sending the second system message according to the uplink signal, obviously, in the transmission scheme shown in fig. 6, the terminal device needs to send the uplink signal after receiving the second system message, that is, the base station cannot determine the downlink beam for sending the second system message by using the uplink signal, and therefore, in order for the terminal devices within the coverage of the base station to receive the uplink transmission parameter, the base station may use multiple antenna ports or multiple beam indexes to send the second system message to the terminal device on N basic time domain resource units, that is, that all the terminal devices need to use different multiple beams to send the system messages. In this embodiment, the basic time domain resource unit is usually an independent transport block, and in this case, the length of the basic time domain resource unit is less than 7 symbols.

Optionally, fig. 7 is a flowchart of a method for transmitting a system message according to a first embodiment of the present invention. On the basis of the embodiment shown in fig. 1, the method provided by this embodiment may further include, before S110:

s100, a base station determines the load state of a target cell of a system message to be sent;

s101, the base station adds indication information for indicating different contents in the first system message according to the load state of the target cell.

In the embodiment of the present invention, the base station may selectively use the transmission manners shown in fig. 4 and fig. 5 for the load degree of the cell within the coverage area of the base station, and in practical application, the manner for the base station to add the indication information may be: when the load state of the target cell is smaller than a preset load threshold value, the base station adds indication information for indicating that the first system message contains uplink transmission parameters; and when the load state of the target cell is greater than or equal to the preset load threshold value, the base station adds indication information for indicating that the first system message does not contain the uplink transmission parameters.

In the embodiments shown in fig. 3 and 4, a suitable downlink beam can be determined through an uplink signal, so that the beam scanning is not required to be performed or the beams participating in the transmission are very few in the transmission of the second system message, and the consumed resources are few, which is suitable for a scenario with a relatively light cell load; the second system message in the embodiments shown in fig. 5 and fig. 6 needs to undergo a beam scanning process, which consumes more resources and is suitable for a situation where the cell load is heavier, so that even though beam scanning is needed, each scanned beam has a greater chance to cover the terminal device under the condition of uniform distribution due to a greater distribution density of the terminal device, and the corresponding efficiency is not low.

It should be noted that, as can be seen from the above analysis of the transmission manners shown in fig. 4 and fig. 6, when the load of a cell is both light and heavy, the methods in the embodiments shown in fig. 3 and fig. 5 need to coexist in the same system, and different segmentation and transmission manners of system messages can be selected according to different scenarios, which is beneficial to improving the overall resource utilization efficiency under different load conditions. In view of the above problem, the embodiment of the present invention provides that the first system message carries indication information for indicating whether the first system message includes the uplink transmission parameter, which solves the problem that the transmission modes shown in fig. 4 and fig. 6 coexist, that is, when the terminal device receives the first system message, it can determine whether there is the uplink transmission parameter in the broadcast channel, so as to select different processing modes. Fig. 8 is a schematic structural diagram of a first system message in a method for transmitting a system message according to an embodiment of the present invention, where the first system message shown in fig. 8 is transmitted in a broadcast channel, and the first system message shown in fig. 8 has 1-bit indication information, specifically indicates whether an uplink transmission parameter is included, if the indication includes the uplink transmission parameter, there is a corresponding bearer for the uplink transmission parameter after the indication information, and if the indication does not include the uplink transmission parameter, a subsequent position is NULL (NULL) or carries other messages.

Optionally, in the embodiment of the present invention, the second system message may include admission control information, and in the embodiments shown in fig. 3 and fig. 4, because the first system message includes an uplink transmission parameter, the base station sends the second system message carrying the admission control information to the first terminal device after receiving an uplink signal sent by the first terminal device; in the embodiments shown in fig. 5 and fig. 6, since the first system message does not include the uplink transmission parameter, the base station directly sends the second system message carrying the admission control information to the terminal device after sending the first system message.

Optionally, in the embodiment of the present invention, whether the first system message carries the uplink transmission parameter may be indicated by using a manner that the first system message carries indication information for indicating different contents. On the one hand, the indicated carrying is typically carried directly, that is, indication information is included in the first system message in a display manner, for example, bit 0 is used to indicate that there is no uplink transmission parameter, and bit 1 is used to indicate that there is an uplink transmission parameter; in addition, besides using a simple indication with 1 bit, the indication information may be further extended, for example, using a 2-bit 00 to indicate that the first system message does not include uplink parameters or to indicate the UE to receive the second system message; 01, 10, 11 indicate that the first system message includes uplink transmission parameters, and 01, 10, 11 can also respectively represent three different uplink configuration parameters, and further extension bits are also allowed. On the other hand, it is also possible to perform the indication in an implicit manner, that is, the indication information is not carried in the first system message in a clear text, but the purpose of the indication information is achieved through an indirect means, that is, the indication information may be represented in one or more of the following forms: the modulation mode, the coding mode and the occupied bandwidth length of the first system message, when the content of the representation form of the indication information is A, the indication information is used for indicating that the first system message contains uplink transmission parameters, when the content of the representation form of the indication information is B, the indication information is used for indicating that the first system message does not contain the uplink transmission parameters, wherein the contents of the representation forms corresponding to A and B are different; for example, when the modulation or coding scheme of the first system message is a, the indication information indicates that the first system message includes the uplink transmission parameter, and when the modulation or coding scheme of the first system message is B, the indication information indicates that the first system message does not include the uplink transmission parameter, and the modulation and/or coding schemes corresponding to a and B are different; for another example, the indication information is represented by an occupied bandwidth of the first system message, when the occupied bandwidth of the first system message is a, the indication information indicates that the first system message includes an uplink transmission parameter, when the occupied bandwidth of the first system message is B, the indication information indicates that the first system message does not include the uplink transmission parameter, and the occupied bandwidths corresponding to a and B are different. The terminal can fully acquire the indication information of whether the uplink transmission parameters are included or not by identifying the modulation mode, the coding mode or the occupied bandwidth length of the first system message in the decoding process.

In the embodiment of the invention, the mode that the first system message carries the indication message for indicating different contents is adopted, so that the effects that the second system message is sent in different modes and the uplink signal sending time of the terminal equipment is different in different application scenes are achieved, different resource bearing and transmission modes can be brought by different segmentation modes of the system message, a method of using beams for sending and receiving is introduced into a new generation mobile communication system, and the transmission and resource bearing modes of all parts in the system message have particularity by combining the beam-related processing; in addition, by designing uniform signaling among different segmentation modes, different segmentation modes can coexist in one system, namely, the proper segmentation mode is used in different application scenes; furthermore, because the PBCH generally notifies the terminal device of the receiving parameter of the second system message in the prior art, if there are not enough resources in the PBCH to notify the terminal device of which resources to receive the second system message, the receiving parameter of the second system message may be sent in various manners provided by the embodiments of the present invention.

The embodiment of the invention provides a storage medium. In the embodiment of the present invention, the storage medium may be configured to be stored in a base station, and the storage medium is configured to execute the method steps in any one of the embodiments shown in fig. 2, fig. 3, fig. 5 and fig. 7.

Fig. 9 is a flowchart of a method for transmitting a system message according to a first embodiment of the present invention. The method for transmitting the system message provided by the embodiment is suitable for the case of transmitting the system message in a new generation mobile communication system, and the method can be executed by a system message transmission device, the system message transmission device is realized by combining hardware and software, and the device can be integrated in a processor of a terminal device and used for being called by the processor. As shown in fig. 9, the method of this embodiment may include:

s210, a terminal device receives a first system message sent by a base station through a broadcast channel, where the first system message includes a receiving parameter and indication information of a second system message, and the indication information is used to indicate whether the first system message includes an uplink transmission parameter.

In the embodiment of the present invention, a manner is provided in which a terminal device receives a system message sent by a base station, and a plurality of cells are provided in a coverage area of the base station, and each cell has a plurality of terminal devices. In this embodiment of the present invention, the system messages to be received by the terminal device at least include the first system message and the second system message, where the first system message and the second system message are messages with higher priorities in the system messages, and it can be understood that the first system message is a part of the minimum messages in fig. 1, and the second system message is the remaining minimum messages in fig. 1. The uplink transmission parameters in the embodiment of the present invention include, for example, resource configuration parameters such as resources, power, and code channels required for uplink transmission by the terminal device, for example, the uplink transmission is an uplink random access signal, and the uplink transmission parameters may include parameters such as a preamble index, time-frequency resources of the random access signal, and power configuration.

In the embodiment of the present invention, the terminal device may receive the first system message and the second system message sent by the base station in multiple times, and receive the first system message through the broadcast channel, where the first system message includes a receiving parameter of the second system message, and the receiving parameter is used to indicate which resources the base station subsequently sends the second system message, and the terminal device may obtain the receiving parameter of the second system message after receiving the first system message, and learn which resources receive the second system message according to the receiving parameter.

S220, the terminal equipment receives the second system message sent by the base station according to the receiving parameter of the second system message.

In the embodiment of the present invention, the first system message received by the terminal device carries the receiving parameter of the second system message, so that both the base station and the terminal device can know which resources the second system message should be sent on, that is, the receiving parameter of the second system message is used to indicate the location of the resource for sending the second system message. For example, if the indication information indicates that the first system message includes the uplink transmission parameter, the first system message further includes the uplink transmission parameter, and the terminal device may perform uplink transmission according to the uplink transmission parameter after receiving the first system message; for another example, if the indication information indicates that the first system message does not include the uplink transmission parameter, the uplink transmission parameter may be carried in the second system message and sent, and the terminal device may perform uplink transmission after receiving the second system message; in both cases, the time for receiving the second system message by the terminal device is different from the content in the second system message.

In the method for transmitting system messages provided in the embodiments of the present invention, a terminal device receives a first system message sent by a base station through a broadcast channel, where the first system message includes a receiving parameter and indication information of a second system message, and the indication information is used to indicate whether the first system message includes indication information of an uplink transmission parameter, and then, the terminal device may receive the second system message sent by the base station according to the receiving parameter of the second system message; in the method provided by this embodiment, the system message is divided into at least two parts, and the content carried in the first system message is reasonably designed, and the second system message is sent in a manner suitable for the current application scenario, so that the problems that when the division manner in the existing LTE system is applied to a new generation mobile communication system, the terminal device needs to perform uplink transmission after receiving the remaining minimum message, and the delay and the overhead of the terminal device in uplink transmission are large are solved; in addition, the problem that the practicability and flexibility of system message sending are poor due to the fact that the division mode in the LTE system is fixed is solved.

Optionally, fig. 10 is a flowchart of a method for transmitting a system message according to a first embodiment of the present invention. It has been described above that when the indication information is used to indicate that the first system message includes the uplink transmission parameter, the first system message further includes the uplink transmission parameter, in this embodiment, S220 may further include, before:

s211, the terminal equipment sends an uplink signal to the base station according to the uplink transmission parameter;

the implementation manner of S220 in this embodiment is: and the terminal equipment receives the second system message sent by the base station on the basic time domain resource unit carrying the second system message according to the receiving parameter of the second system message.

In this embodiment, when the second system message includes the uplink transmission parameter, after S220 in this embodiment, the method may further include: and S230, the terminal equipment sends other uplink signals according to the uplink transmission parameters in the second system message.

Also, referring to the transmission diagram shown in fig. 4, in the manner of sending the system message provided in this embodiment, the first system message carries the uplink transmission parameter, and after receiving the first system message, the terminal device may attempt uplink transmission, where the uplink transmission is most likely to be transmission of a random access signal. In the case of multi-beam transmission and reception, the uplink transmission is, for example, transmission of a random access signal, and the uplink transmission and the downlink beam have a mapping relationship, so that the base station can determine, by receiving the uplink signal, a downlink beam having a mapping relationship with the uplink signal, that is, determine which beam is an appropriate downlink beam, so as to use the appropriate downlink beam when transmitting the second system message, and when the appropriate downlink beam is selected, the second system message can be transmitted and received only using the determined downlink beam; optionally, in addition to the determined downlink beam, the second system message may also be sent and received by using a part of downlink beam adjacent to the determined downlink beam, so as to improve the probability and stability of beam reception, accordingly, the terminal device may receive the second system message only on the determined downlink beam or a peripheral part of downlink beam, and the receiving parameter of the second system message is also sent in the first system message in the broadcast channel. Because the second system message can specify a proper downlink beam through the mapping relationship, multi-beam transmission is not required to be adopted in resource arrangement, and the second system message can be transmitted in a normal data packaging manner in resource use, that is, the second system message can be transmitted by using a basic time domain resource unit containing a control signal and a data signal, wherein the length of the basic time domain unit is greater than or equal to 7 symbols; optionally, the basic time domain resource unit may also be an independent transport block, and in this case, the length of the basic time domain resource unit is less than 7 symbols.

Optionally, fig. 11 is a flowchart of a method for transmitting a system message according to the first embodiment of the present invention. It has been described above that when the indication information is used to indicate that the first system message does not include the uplink transmission parameter, a manner of receiving the second system message by the terminal device is different from the embodiment shown in fig. 10, that is, the implementation manner of S220 in this embodiment may be: the terminal equipment receives a second system message sent by the base station on N basic time domain resource units bearing the second system message according to the receiving parameter of the second system message; wherein N is a positive integer greater than 1.

In this embodiment, when the second system message includes the uplink transmission parameter, after S220 in this embodiment, the method may further include: and S230, the terminal equipment sends the uplink signal according to the uplink transmission parameter in the second system message.

Also, referring to the transmission diagram shown in fig. 6, in the manner of sending the system message provided in this embodiment, the indication information in the first system message received by the terminal device is used to indicate that the first system message does not include the uplink transmission parameter, and the difference from the transmission diagram shown in fig. 4 is that whether the terminal device can send an uplink signal according to the uplink transmission parameter before receiving the second system message, and whether the base station can determine a downlink beam used for sending the second system message according to the uplink signal, obviously, in the transmission scheme shown in fig. 6, the terminal device needs to send the uplink signal after receiving the second system message, that is, the base station cannot determine the downlink beam used for sending the second system message by using the uplink signal, and therefore, in order to make the terminal devices within the coverage of the base station can receive the uplink transmission parameter, the base station may use multiple antenna ports or multiple beam indexes to send the second system message to the terminal device on N basic time domain resource units, that the second system message needs to be sent by using multiple beams all to cover terminal devices in different locations; correspondingly, the terminal device may receive the second system message sent by the base station in the N basic time domain resource units by using multiple antenna ports or multiple beam indexes. In this embodiment, the basic time domain resource unit is usually an independent transport block, and in this case, the length of the basic time domain resource unit is less than 7 symbols.

It should be noted that, in the embodiment of the present invention, if the indication information in the first system message is used to indicate that the first system message includes the uplink transmission parameter, a manner for the base station to confirm the specific content indicated by the indication information according to the cell load status is the same as that in the embodiment shown in fig. 7, and therefore, details are not repeated here; the method can also realize that different segmentation modes of the system message coexist in the same system, and select a proper segmentation and transmission mode of the system message in different application scenes, thereby being beneficial to improving the overall resource utilization efficiency under different load conditions.

Optionally, in the embodiment of the present invention, the second system message may also include admission control information, and in the embodiment shown in fig. 10, since the first system message includes an uplink transmission parameter, the terminal device receives the first system message, and receives the second system message carrying the admission control information, which is sent by the base station, after sending an uplink signal according to the uplink transmission parameter; in the embodiment shown in fig. 11, since the first system message does not include the uplink transmission parameter, the terminal device may receive the second system message carrying the admission control information sent by the base station after receiving the first system message.

Optionally, in the embodiment of the present invention, whether the first system message carries the uplink transmission parameter may be indicated by using a manner that the first system message carries indication information for indicating different contents. On one hand, the indicated carrying is typically carried directly, that is, indication information is included in the first system message in a displayed manner, for example, bit 0 is used to indicate that there is no uplink transmission parameter, and bit 1 is used to indicate that there is an uplink transmission parameter; in addition, besides the simple indication with 1 bit, the indication information may be further extended, for example, 2 bits of 00 are used to indicate that the first system message does not include uplink parameters or indicate the UE to receive the second system message; 01, 10, 11 indicate that the first system message includes uplink transmission parameters, and 01, 10, 11 can also respectively represent three different uplink configuration parameters, and further extension bits are also allowed. On the other hand, it is also possible to use an implicit method to indicate, that is, the plaintext does not carry the indication information in the first system message, but the purpose of indicating the information is achieved by an indirect method, in this method, after S210, the embodiment may further include: the terminal equipment confirms the indication information through the content of the representation form of the indication information, and the indication information is represented by one or more of the following forms: the modulation mode, the coding mode and the occupied bandwidth length of the first system message; when the content of the representation form of the indication information is A, the indication information is used for indicating that the first system message contains the uplink transmission parameter, and when the content of the representation form of the indication information is B, the indication information is used for indicating that the first system message does not contain the uplink transmission parameter, wherein the contents of the representation forms corresponding to A and B are different.

In the embodiment of the invention, the mode that the first system message carries the indication message for indicating different contents is adopted, so that the effects that the second system message is sent in different modes and the uplink signal sending time of the terminal equipment is different in different application scenes are achieved, different resource bearing and transmission modes can be brought by different segmentation modes of the system message, a method of using beam for sending and receiving is introduced into a new generation mobile communication system, and the transmission and resource bearing modes of all parts in the system message have particularity by combining the related processing of the beam; in addition, by designing uniform signaling among different segmentation modes, different segmentation modes can coexist in one system, namely, the proper segmentation mode is used in different application scenes; furthermore, because the PBCH generally notifies the terminal device of the receiving parameter of the second system message in the prior art, if there are not enough resources in the PBCH to notify the terminal device of which resources to receive the second system message, the receiving parameter of the second system message may be sent in various manners provided by the embodiments of the present invention.

It should be noted that, in the indication information in the embodiment of the present invention, when indicating that the first system message includes the uplink transmission parameter, the first system message may further include the uplink transmission parameter, and default to that the first system message does not include the reception parameter of the second system message; when the indication information includes the receiving parameter of the second system message in the first system message, the first system message may further include the receiving parameter of the second system message, and the default is that the first system message does not include the uplink transmission parameter.

And S320, the base station sends a second system message to the terminal equipment according to the content indicated by the indication information.

The method provided in this embodiment is different from the above embodiments in that the first system message sent by the base station only includes the uplink transmission parameter or the reception parameter of the second system message. In a possible implementation manner of the embodiment of the present invention, when the first system message includes a receiving parameter of the second system message, a specific manner of sending the second system message by the base station is the same as that in the embodiment shown in fig. 5, and also refer to a transmission diagram shown in fig. 6, where the terminal device in this embodiment needs to send an uplink signal after receiving the second system message, that is, the base station cannot determine a downlink beam used for sending the second system message by using the uplink signal, so that, in order to enable the terminal devices within a coverage of the base station to receive the uplink transmission parameter, the base station may use multiple antenna ports or multiple beam indexes to send the second system message to the terminal device, that is, the second system message needs to be sent by using multiple beams to cover terminal devices in different positions; in another possible implementation manner of the embodiment of the present invention, when the first system message includes the uplink transmission parameter, the base station further needs to send a reception parameter of the second system message to the terminal device, which is different from the manner in which the base station sends the system message in the foregoing embodiments, and a specific implementation manner of this case is specifically described in the following embodiments. The second system message may be in various forms, and may be information in SIB like LTE, or a system message transmitted in a data shared channel, or a system message transmitted in a second PBCH other than PBCH.

Optionally, in this embodiment of the present invention, it has been described above that the indication information may indicate different contents, and if the indication information is used to indicate that the first system message includes a receiving parameter of a second system message, it implicitly implies that the terminal needs to receive the second system message first and then perform uplink transmission; if the indication information is used to indicate that the first system message includes the uplink transmission parameter, the indication information may also be extended to indicate which uplink transmission parameter is included in the first system message, that is, the indication information may also be used to indicate different uplink transmission parameter configurations. For example, 01, 10, and 11 of 2 bits may be used to respectively represent the configuration of three different uplink configuration parameters.

Optionally, fig. 18 is a flowchart of another method for transmitting a system message according to a second embodiment of the present invention. It has been described above that when the indication information is used to indicate that the first system message includes the uplink transmission parameter, the first system message further includes the uplink transmission parameter, and this embodiment may further include, before S320:

S311, the base station receives an uplink signal sent by the first terminal device according to the uplink transmission parameter;

s312, the base station sends a downlink signal for responding to the uplink signal to the first terminal device, where the downlink signal includes a receiving parameter of the second system message.

The implementation manner of S320 in this embodiment is: and the base station sends the second system message to the first terminal equipment on the basic time domain resource unit carrying the second system message according to the receiving parameter of the second system message.

The method provided in this embodiment, after S312, may further include:

s313, the base station determines the resource for sending the second system message according to the resource of the uplink signal; the resources of the second system message include one or more of antenna ports and beam indices.

As shown in fig. 19, which is a schematic diagram of transmission of a system message in the method for transmitting a system message provided in the embodiment shown in fig. 18, it can be seen from fig. 19 that, in the manner of transmitting a system message provided in this embodiment, a base station carries parameters required for uplink transmission, which are sent in the remaining minimum message in the flow shown in fig. 1, in the minimum message in a broadcast channel, and sends the parameters, that is, uplink transmission parameters are carried in a first system message, and after receiving the first system message, a terminal device may attempt uplink transmission, which is most likely to be transmission of a random access signal. In the case of multi-beam transmission and reception, the uplink transmission is, for example, transmission of a random access signal, and the uplink transmission and the downlink beam have a mapping relationship, so that the base station can determine, by receiving the uplink signal, a downlink beam having a mapping relationship with the uplink signal, that is, determine which beam is an appropriate downlink beam, so as to use the appropriate downlink beam when transmitting the second system message, and when the appropriate downlink beam is selected, the second system message can be transmitted and received only using the determined downlink beam; optionally, the second system message may be sent by using the determined downlink beam, or may be sent and received by using a part of downlink beams adjacent to the determined downlink beam, so as to improve the probability and stability of beam reception, and after receiving the second system message, the terminal device may send other uplink signals according to the uplink transmission parameters in the second system message. It can be seen that the transmission scheme shown in fig. 19 is different from that shown in fig. 4, in that the first system message does not have the receiving parameter of the second system message, and therefore, the base station may send the receiving parameter of the second system message to the terminal device through the random access response signaling in the random access procedure, whereas the transmission scheme shown in fig. 4 does not need to send the downlink signal for responding to the uplink signal.

Optionally, the basic time domain resource unit in the embodiment of the present invention may include a control signal and a data signal, where the length of the basic time domain resource unit is greater than or equal to 7 symbols; alternatively, the basic time domain resource unit may also be an independent transport block, where the length of the basic time domain resource unit is less than 7 symbols.

Also, referring to the transmission schematic diagram of the system message shown in fig. 6, the transmission manner of the system message in this embodiment is the same as that shown in fig. 6, that is, the base station may use multiple antenna ports or multiple beam indexes to send the second system message to the terminal device on N basic time domain resource units, which is not described herein again. In this embodiment, the basic time domain resource unit is usually an independent transport block, and in this case, the length of the basic time domain resource unit is less than 7 symbols.

Optionally, in the embodiment of the present invention, whether the first system message carries the uplink transmission parameter may be indicated by using a manner that the first system message carries indication information for indicating different contents. On the one hand, the indicated carrying is typically carried directly, that is, indication information is included in the first system message in a display manner, for example, bit 0 is used to indicate that there is no uplink transmission parameter, and bit 1 is used to indicate that there is an uplink transmission parameter; in addition, besides the simple indication with 1 bit, the indication information may be further extended, for example, 2 bits of 00 are used to indicate that the first system message does not include uplink parameters or indicate the UE to receive the second system message; 01, 10, 11 indicate that the first system message includes uplink transmission parameters, 01, 10, 11 can also respectively represent three different uplink configuration parameters, and further extension bits are also allowed. On the other hand, it is also possible to use an implicit manner to indicate, that is, the indication information is not carried in the clear text in the first system message, but the purpose of the indication information is achieved by an indirect means, that is, the indication information may be represented in one or more of the following forms: the modulation mode, the coding mode and the occupied bandwidth length of the first system message, when the content of the representation form of the indication information is A, the indication information is used for indicating that the first system message contains uplink transmission parameters, when the content of the representation form of the indication information is B, the indication information is used for indicating that the first system message does not contain the uplink transmission parameters, wherein the contents of the corresponding representation forms of A and B are different.
