All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a system message acquiring method according to an embodiment of the present application. The execution main body of the system message acquisition method may be the system message acquisition device provided in the embodiment of the present application, or user equipment integrated with the system message acquisition device, where the system message acquisition device may be implemented in a hardware or software manner, and the user equipment may be a smart phone, a tablet computer, a palm computer, a notebook computer, or the like. The system message acquisition method may include:
101. and determining the system message identification and the acquisition mode to be acquired.
The system message identifier may indicate a system message requested by the user equipment, and a correspondence between the system message identifier and the system message may be manually specified or may be generated by a machine. Receiving the system message sent by the base station and performing operations such as setting or modifying based on the system message are necessary conditions for the user equipment to guarantee basic communication. The number of the system message identifications corresponding to one system message can be one or more, and the number of the system message identifications can be determined based on the requirement of the user equipment. In particular, the system messages may include a system main message, system message 1, system message 2, system message3, system message4, system message 5, system message 6, system message 7, system message 8, and system message 9. Among them, the system messages 2 to 9 can be classified as other system messages. For example, the system message identifier corresponding to the system message3 may be SI3, SI3 and S3, and so on.
The obtaining mode may indicate a processing mode of the base station and the user equipment for the system message corresponding to the system message identifier, the obtaining mode may be a processing mode such as a channel used by the base station to transmit the system message, a setting mode of the base station for the system message, and the like in a process that the system message is sent to the user equipment through the base station, and the system message may also be a receiving mode of the user equipment for receiving the system message corresponding to the system message identifier sent by the base station, or a setting mode of the system message corresponding to the system message identifier, and the like. The obtaining mode is appointed by the user equipment, the base station selects and adopts a specific obtaining mode through the obtaining mode sent by the user equipment, and the user equipment correspondingly adjusts parameters according to the obtaining mode to receive data sent by the base station.
The system message identifier and the acquisition mode to be acquired are determined by the user equipment based on the system process and the functions required by the user equipment, or manually requested through an external device connected to the user equipment or a specific interface on the user equipment. The number of the system message identifications to be acquired can be flexibly set according to the actual situation. For example, the system message identifier to be acquired may be SI3 or SI4, or a4, and the acquisition mode may be mode M, or the like.
102. When the sending opportunity of the physical uplink control channel arrives, generating a system message acquisition request which accords with the channel format of the physical uplink control channel based on the system message identifier, wherein the system message acquisition request carries the system message identifier.
The transmission opportunity may be a single time period or a time period set composed of a plurality of time periods. The transmission occasions for different channels may be different. The transmission timing of the channel is an attribute of the channel, and the channel indicated by the transmission timing may be determined by the transmission timing, or the transmission timing of the channel may be determined by the channel. The transmission opportunity of the physical uplink control channel indicates a time period for data transmission and data reception by the base station, the user equipment and the like through the physical uplink control channel in the transmission process. For example, the time duration of each time period of the transmission opportunity is 5ms, the interval between the start points of two adjacent time periods of the transmission opportunity is 2ms, and the transmission opportunity includes 2 ten thousand time periods.
The channel format indicates different processing modes of the message to be transmitted in the channel, for example, the channel formats are different, and the coding mode, scrambling mode, or modulation mode of the message to be transmitted may be different. A Physical Uplink Control Channel (PUCCH) belongs to one of channels used by a base station and a user equipment for activities such as data transmission. The channel format of the physical uplink control channel is designed according to different requirements and application scenarios, and includes 5 channel formats, for example, PUCCH0, PUCCH1, PUCCH2, PUCCH3, and PUCCH 4. The user equipment selects a proper channel format according to the size of data to be transmitted through the PUCCH and the sending opportunity of the data.
In some embodiments, when a transmission opportunity of a physical uplink control channel arrives, generating a system message acquisition request conforming to a channel format of the physical uplink control channel based on a system message identifier includes: when the sending opportunity of the physical uplink control channel arrives, acquiring the byte number range of the system message identifier; determining a physical uplink control channel with a matched channel format based on the byte number range; and generating a corresponding system message acquisition request based on the determined channel format according to the system message identifier.
Specifically, the byte number range of the system message identifier may be measured and calculated by the user equipment, or the byte number range of a single system message identifier may be predetermined, and then the user equipment determines the number of the system message identifiers, and performs calculation by combining the predetermined byte number, so as to obtain the byte number range of the system message identifier. Different channel formats correspond to different byte number ranges, the obtained byte number range of the system message identifier is compared with the byte number range corresponding to the channel format to determine the channel format to which the byte number range of the system message identifier belongs, namely to determine that the system message identifier has the physical uplink control channel matched with the channel format. And after the channel format is determined, processing the system message identifier based on the processing mode indicated by the channel format to obtain a system message acquisition request.
In some embodiments, the system message identifier carries a number value, and when the transmission opportunity of the physical uplink control channel arrives, before acquiring the byte number range of the system message identifier, the method further includes: acquiring the corresponding sending time of the system message identifier on the physical uplink control channel based on the number value; and detecting whether the current sending opportunity belongs to the corresponding sending opportunity or not at set time intervals.
Specifically, the system message identifier carries a number value, which may be added to the system message identifier by the user equipment according to actual requirements, or may be set by the user equipment at the generation stage. The number value is used as a known quantity, and the corresponding sending time of the system message identifier on the physical uplink control channel can be obtained through the number value, for example, the number value is put into a set protocol or a set formula for judgment or calculation, so as to obtain the corresponding sending time of the physical uplink control channel. Then, the ue detects whether the current transmission timing belongs to the corresponding transmission timing, if the current transmission timing belongs to the corresponding transmission timing, the current transmission timing, that is, the transmission timing of the physical uplink control channel, arrives, and if the current transmission timing does not belong to the corresponding transmission timing, the ue performs detection again after 5ms (that is, a set time interval), and repeats the detection and determination process until it is detected that the current transmission timing (the transmission timing when performing the detection operation) belongs to the corresponding transmission timing.
103. And sending a system message acquisition request to the base station through a physical uplink control channel.
In some embodiments, when a transmission opportunity of a physical uplink control channel arrives, generating a system message acquisition request conforming to a channel format of the physical uplink control channel based on a system message identifier may include: when the sending opportunity of the physical uplink control channel arrives, if other messages exist at the current sending opportunity, determining a channel format conforming to the physical uplink control channel based on the system message identifier and the other messages; generating a system message acquisition request which accords with a channel format of a physical uplink control channel based on a system message identifier; and generating other data which conforms to the channel format of the physical uplink control channel based on the other message identification. Sending a system information acquisition request to a base station through a physical uplink control channel, wherein the system information acquisition request can comprise; multiplexing the system information acquisition request and other data through a physical uplink control channel to obtain data to be sent; and sending data to be sent to a base station.
Specifically, other messages may exist at the current transmission opportunity of the PUCCH, for example, a downlink channel feedback message or other messages such as response information to the hybrid automatic repeat request mechanism may exist at the current transmission opportunity of the PUCCH, and since the channel format may be determined based on the byte number range of the data to be transmitted, if other messages to be transmitted through the PUCCH exist in the user equipment at the current transmission opportunity, the channel format conforming to the physical uplink control channel is determined based on the system message identifier and the other messages, that is, the channel format conforming to the physical uplink control channel is determined based on the sum of the byte number ranges of the system message identifier and the other messages. Then, processing the system message identification based on the processing mode corresponding to the determined channel format to generate a system message acquisition request; and processing other messages based on the processing mode corresponding to the determined channel format to generate other data, for example, if the channel format determined based on the system message identifier and other messages is PUCCH3, processing the system message identifier and other messages according to the processing mode indicated by PUCCH3 to generate a system message acquisition request and other data. Because the data to be sent at the current sending opportunity includes the system message acquisition request and other data, in order to ensure that each message to be sent is sent on time on the PUCCH without mutual interference, each piece of data to be sent needs to be multiplexed, that is, the system message acquisition request and other data are multiplexed, the data to be sent can be obtained by executing multiplexing operation, and then the data to be sent is sent to the base station.
In some embodiments, multiplexing the system information acquisition request and other data through a physical uplink control channel to obtain data to be sent includes: allocating frequency segments and/or time segments to the system information acquisition request and other data based on the physical uplink control channel, wherein the frequency segments and/or the time segments correspond to the system information acquisition request or other data one to one; and fusing the frequency section and/or the time section with a system information acquisition request or other data to obtain data to be sent.
Wherein, the frequency segment refers to different transmission frequency ranges of the signal, and the time segment refers to different transmission time ranges of the signal. The frequency segment and the time segment may be expressed in the form of a function, an image, or the like. For example, a frequency band range of one channel is C1 to C2, and the frequency band range is divided into 50 frequency bins. For another example, the time range of the transmission timing is D1 to D2, and the transmission timing is divided into 100 equal parts to obtain 100 time slots. In order to transmit the used PUCCH including the system message acquisition request and other data without interfering with each other, the system message acquisition request and other data may be set to different frequency segments or time segments, for example, the system message acquisition request is fused with a signal with a frequency segment of C1, so that the system message acquisition request is transmitted on C1; by fusing other data with the signal of the frequency band C2, the system message acquisition request is transmitted on the C2, and by this operation, the system message acquisition request and other data can be transmitted at the same time. The system information acquisition request and other data can be subjected to frequency band fusion, time period fusion, frequency band fusion first and time period fusion second, and specific operation can be flexibly selected by combining with an actual application scene.
104. And receiving the system message returned by the base station according to the system message acquisition request based on the acquisition mode.
In some embodiments, receiving, based on the obtaining manner, a system message returned by the base station according to the system message obtaining request includes: determining a system message acquisition channel and a system message acquisition mode based on the acquisition mode; and receiving the system message returned by the base station according to the system message acquisition request through a system message acquisition channel and a system message acquisition mode.
In some embodiments, the system message acquiring method indicates setting noise, setting a pulse signal, and setting a decoding method, and receiving a system message returned by the base station according to the system message acquiring request through a system message acquiring channel and the system message acquiring method includes: receiving data returned by the base station through a system message acquisition channel; and processing the data based on the set noise, the set pulse signal and the set coding mode to obtain the system message obtained according to the system message acquisition request.
Because data is interfered by noise brought by an external environment in the process of transmitting through a channel, noise reduction operation can be performed on the data acquired through the channel, and the set noise is a simulation of the noise of the external environment, for example, gaussian noise can be used as the set noise. Due to the channel transmission requirements, the actually transmitted data waveform (i.e., the data received by the user equipment) is not a baseband signal that can be directly decrypted and decoded. The set pulse signal is a tool that assists in converting data to a baseband signal. The decoding method is usually set to correspond to the encoding method adopted when the sending end processes data before data transmission, and encoding is to convert one data form into another data form suitable for channel transmission. Therefore, the decoding mainly converts the form of the transmitted data into a data form readable and understandable by other objects, such as characters, codes and the like. It should be noted that the order of processing the received data is not limited, and the processing manner and steps are not limited to the above three, and the specific case is based on the processing steps and manner in the actual processing process.
The method and the device for acquiring the system message can determine the system message identification and the acquiring mode to be acquired, when the sending time of the physical uplink control channel is up, a system message acquiring request which is in accordance with the channel format of the physical uplink control channel is generated based on the system message identification, the system message acquiring request carries the system message identification, then the system message acquiring request is sent to a base station through the physical uplink control channel, and finally the system message returned by the base station according to the system message acquiring request is received based on the acquiring mode. In the embodiment of the application, the physical uplink control channel sends a system message acquisition request, and the user equipment can receive the system message returned by the base station according to the system message acquisition request.
In order to better implement the system message acquisition method provided by the embodiment of the present application, an embodiment of the present application further provides a device based on the system message acquisition method.
