Technical Field

The present application relates to the field of communications, and in particular, to a method, a base station, and a terminal for feeding back a signal state.

background

And the connection of things in the internet of things era can enable more than one billion things to be connected into a network, which has higher requirements on traditional communication technology. In fact, communication technologies currently used for the development of the internet of things are being developed worldwide. The method and the device have the advantages that the throughput of uplink users can be improved through the rapid feedback of the uplink services in the communication system of the Internet of things, and meanwhile the power consumption of the terminal can be reduced.

In a communication system, a base station allocates a dedicated feedback Channel on a downlink Physical Hybrid automatic repeat request Indicator Channel (PHICH) for each scheduled terminal to indicate whether a corresponding Channel correctly receives uplink data sent by the terminal. Because the time for sending the uplink data by the terminal and the channel resource occupied by sending the uplink data are scheduled in advance by the base station, the resource for sending the PHICH feedback bit on the base station side can be uniquely determined for both the terminal and the base station, so that whether the uplink data sent by the base station to the terminal is correctly received or not can be correctly fed back.

however, this technique is only applicable to a scheduling system, and in a non-scheduling system, since the timing for transmitting uplink data and the channel resources occupied by transmitting uplink data are determined by itself, the base station cannot know in advance which terminal the acquired uplink data is transmitted by, and therefore the base station cannot guarantee correct and effective feedback of whether the base station correctly receives the uplink data transmitted by the terminal.

Referring to the communication system shown in fig. 1, the communication system includes a base station and a terminal, where the base station is a node for managing the terminal and controlling the terminal to receive and transmit data in a cellular network, and the terminal is a user equipment in the cellular network that communicates with the base station. The terminal has one or more transmit antennas and the base station has multiple receive antennas. The base station and the terminal communicate with each other through an air interface technology.

The method and the device have the advantages that the throughput of uplink users can be improved through the rapid feedback of the uplink services in the communication system of the Internet of things, and meanwhile the power consumption of the terminal can be reduced. For each scheduled terminal, the base station allocates a dedicated feedback Channel on a downlink Physical Hybrid automatic repeat request Indicator Channel (PHICH) to indicate whether the corresponding Channel correctly receives uplink data sent by the terminal. Because the time for sending the uplink data by the terminal and the channel resource occupied by sending the uplink data are scheduled in advance by the base station, the resource for sending the PHICH feedback bit on the base station side can be uniquely determined for both the terminal and the base station, so that whether the uplink data sent by the base station to the terminal is correctly received or not can be correctly fed back. However, this technique is only applicable to a scheduling system, and in a non-scheduling system, since the timing for transmitting uplink data and the channel resources occupied by transmitting uplink data are determined by itself, the base station cannot know in advance which terminal the acquired uplink data is transmitted by, and therefore the base station cannot guarantee correct and effective feedback of whether the base station correctly receives the uplink data transmitted by the terminal.

To solve the problem, the technical scheme provided by the embodiment of the application is as follows: a base station acquires an uplink data set in an uplink channel; then the base station determines the identification information of each terminal corresponding to each uplink data in the uplink data set; then the base station acquires a target prime number corresponding to each terminal for sending uplink data according to the identification information of each terminal and a preset mapping relation; then the base station calculates the target prime number according to a first formula to obtain a product value; and finally, the base station sends a feedback message generated by coding the product value to the terminal so that the terminal determines the uplink data state according to the feedback message.

Specifically, referring to fig. 2, an embodiment of a method for feeding back a signal state in an embodiment of the present application includes:

201. And the terminal sends uplink data to the base station through the uplink channel.

in the communication system of the internet of things, a terminal needs to send uplink data of an uplink service to a base station through an uplink channel.

in this embodiment, the number of the terminals may be one or multiple, and the specific number of the terminals is not limited herein. When there are multiple terminals, the terminals may be in different uplink channels, respectively. In this embodiment, an uplink channel group is taken as an example, and the uplink channel group includes 4 uplink channels, which are an uplink channel a, an uplink channel B, an uplink channel C, and an uplink channel D. The terminal A sends uplink data through the uplink channel A, the terminal B and the terminal C send uplink data through the uplink channel B, the terminal D sends uplink data through the uplink channel C, and no terminal sends uplink data on the uplink channel D.

202. and the base station determines the identification information of the terminal corresponding to the uplink data.

after receiving the uplink data, the base station analyzes the uplink data and then acquires identification information of a terminal sending the uplink data.

203. And the base station determines a target prime number corresponding to the identification information.

After determining the identification information, the base station matches the identification information with a preset mapping relation to determine a target prime number corresponding to the identification information.

In this embodiment, the predetermined mapping relationship is a mapping relationship between the identification information and a prime number. The preset mapping relationship may further include a first prime number and a second prime number, where the first prime number is used to indicate that there is no uplink data in the uplink channel, and the second prime number is used to also indicate that the base station has correctly received the identification information corresponding to the uplink data currently and correctly received by the base station at the previous time. The first prime number and the second prime number may be twin prime numbers or prime numbers defined by other factors, and are not limited herein.

In practical application, the preset mapping relationship is composed of a plurality of sub-mapping relationships, and the sub-mapping relationships are mapping relationships between identification information and prime numbers in each uplink channel. Wherein the mapping relationship of each uplink channel is different from each other. For example, in this embodiment, it is assumed that the mapping relationship a of the uplink channel a is as follows: p (a, 0-5) {59, 61, 67, 71, 73, 79 }; the mapping relationship B of the uplink channel B is as follows: p (B, 0-5) {101, 103, 107, 109, 113, 127 }; the mapping relationship C of the uplink channel C is as follows: p (C, 0-5) {137, 139, 149, 151, 157, 163 }; the mapping relationship D of the uplink channel D is as follows: p (D, 0-5) {179, 181, 191, 193, 197, 199 }. The first number in each mapping relation is the first prime number, and the second number is the second prime number. The preset mapping relationship comprises a mapping relationship A, a mapping relationship B, a mapping relationship C and a mapping relationship D. Assuming that the prime number mapped by the terminal a on the uplink channel a is P (a, 3) ═ 67; a prime number obtained by mapping the terminal B on the uplink channel B is P (B, 4) 109; the prime number obtained by mapping the terminal C on the uplink channel B is P (B, 3) ═ 107; the prime number of the terminal D on the uplink channel C obtained by mapping is P (C, 5) ═ 163.

In this embodiment, there are various ways for the base station to determine the target prime number of the identification information according to the preset mapping relationship, which are specifically as follows:

In a possible implementation manner, the base station represents a target prime number of an uplink channel of the uplink data by using the first prime number, and represents a target prime number of uplink data that has been correctly received by the base station at the previous time, of identification information corresponding to the uplink data that is correctly received by the base station at the present time, by using the second prime number. For example, in this embodiment, if it is assumed that the uplink data sent by the terminal B is not correctly received, the uplink data sent by the terminal C at the previous time is correctly received, the uplink data sent at the current time is also correctly received, the uplink data sent by the terminal a is correctly received for the first time, and the uplink data sent by the terminal D is correctly received for the first time, the target prime number at this time includes (67, 103, 163, 179).

in another possible implementation manner, the base station only takes the prime number corresponding to the identification information corresponding to the correctly received uplink data as the target prime number. For example, in this embodiment, if it is assumed that the uplink data sent by the terminal B is not correctly received, the uplink data sent by the terminal C at the previous time is correctly received, the uplink data sent at the current time is also correctly received, the uplink data sent by the terminal a is correctly received for the first time, and the uplink data sent by the terminal D is correctly received for the first time, then the target prime number at this time includes (67, 107, 163).

204. and the base station calculates the target prime number by using a first formula to obtain a product value.

The base station determines the target prime number and then utilizes the target prime number by P_M＝P₁*P₂*…*P_nAnd (n epsilon Z) formula is calculated to obtain the product value. Wherein, P_Mis the product value, P₁Is a first target prime number, P₂Is a second target prime number, P_nIs the nth target prime number, the value of n is a positive integer, and the first target prime number and the second target prime number are contained in the target prime number.

In this embodiment, if the base station uses the first prime number and the second prime number, the product value of the target prime number is P_M67, 103, 163, 179, 201350477. If the base station determines the target prime number only for the correctly received data, the product value of the target prime number is P_M＝67*107*163＝1168547。

205. and the base station encodes the product value to obtain the feedback message.

And the base station codes the product value after obtaining the product value to obtain the feedback message.

In this embodiment, the base station may perform coding in multiple ways, which are specifically as follows:

in another possible implementation manner, the base station obtains the effective bit number that can be carried by the uplink channel; then determining the prime number of the maximum value which can be expressed by the effective bit number as the maximum prime number; then, the base station performs a modular operation on the product value to the maximum prime time line to obtain a remainder, and the remainder is used as the feedback message. For example, if the number of effective bits that the uplink channel can carry is 12 bits, the prime number of the maximum value that the 12-bit binary can represent is 4097, and the remainder is G201350477 and 4097 × 49145 is 3412. I.e., the feedback message is 3412.

In another possible implementation manner, the base station acquires binary data of the product value; and then the base station carries out Cyclic Redundancy Check (CRC) coding on the binary data to obtain coded data, and the coded data is used as the feedback message.

In another possible implementation manner, the base station calculates the product value by using a second formula to obtain a target value, and uses the target data as the feedback message. The second formula is: p₃＝P_M-P₄*P₅+ 1; wherein, P₃Is the target value, P_MIs the product value, P₄For a predetermined defined prime number, P₅is a pre-defined prime number. In this embodiment, the P₄And the P₅Can be defined in advance, and define what value, and is not limited here. In this example, P_MTaking 201350477 as an example, if P is₄Is defined as 4097, P₅defined as 49145, the target value P₃201350477 and 4097 × 49145+1 × 3413. I.e., the feedback message is 3413.

206. And the base station sends the feedback message to the terminal.

the base station sends the feedback message to the terminal.

In practical application, the base station sends the feedback message to a plurality of terminals belonging to its uplink channel group.

207. And the terminal determines the uplink data state according to the feedback message.

and after receiving the feedback message, the terminal decodes the feedback message to obtain the product value. Then the terminal determines whether the product value is divided by the prime number corresponding to the terminal, if so, the terminal determines that the uplink data is correctly received by the base station; if not, the terminal determines that the uplink data sent by the terminal is not correctly received.

In this embodiment, the terminal decodes the feedback message differently according to the difference of the received feedback message, which specifically includes the following steps:

in a possible implementation manner, if the terminal directly receives the product value, the terminal may directly use the product value to divide by the prime number of the terminal itself, so as to determine the state of the uplink data sent by the terminal. If the terminal a receives the product value 201350477 and its own prime number is 67, the division 201350477 by 67 equals 3005231, i.e. the product value can be divided by the own prime number of the terminal a, which also indicates that the uplink data sent by the terminal a is correctly received by the base station. And if the terminal B receives the product value 201350477 and its own prime number is 109, then the division of 201350477 by 109 equals 1847252.08, i.e. the product value cannot divide the own prime number of the terminal B by an integer, which indicates that the uplink data sent by the terminal B is not correctly received by the base station.

In one possible implementation, the terminal receives the remainder, and then the terminal calculates the product value by using the remainder and the maximum prime number, and then the terminal divides the product value by its own prime number, thereby determining the state of the uplink data sent by the terminal.

in this embodiment, since the terminal knows the remainder and the maximum prime number, but does not know the multiple of the product value divided by the maximum prime number, the terminal may calculate each prime number in the predetermined mapping relationship to obtain a trial product, and calculate the trial product, the remainder and the maximum prime number to obtain a multiple with the highest reliability, and then obtain the product value with the highest reliability according to the multiple.

In another possible implementation manner, when the terminal receives the encoded data, the terminal obtains the product value by using CRC check, and then the terminal divides the product value by the prime number of the terminal itself, thereby determining the state of the uplink data sent by the terminal.

in another possible implementation manner, when the terminal receives the target value, the terminal obtains the product value according to a third formula and the target value by using the terminal, and then the terminal determines the state of the uplink data sent by the terminal by dividing the product value by the prime number of the terminal itself.

Wherein the third formula is: p_M＝P₃+P₄*P₅-1；P₃is the target value, P_MIs the product value, P₄For a predetermined defined prime number, P₅Is a pre-defined prime number.
