Detailed Description
As shown in fig. 1, the present invention discloses an information sending method in the internet of things, which, as embodiment 1 of the present invention, includes the following steps that are sequentially executed:
step S1: a second communication node receives first configuration information sent by a first communication node, and stores the first configuration information in a memory, wherein the first configuration information comprises 3 types of channel coding mode configuration information, N pieces of access sequence group configuration information, and N pieces of data resource configuration information, N is an integer greater than or equal to 1, and the 3 types of channel coding mode configuration information are respectively polarization codes, low-density parity check codes, polarization codes and low-density parity check code mixed codes;
step S2: the second communication node acquires an information source data service bit sequence which needs to be sent to the first communication node, and determines the first configuration information according to the first LOG2(N) bits of the information source data service bit sequence to determine a candidate access sequence group which needs to be used;
step S3: the second communication node determines candidate data resources according to the (LOG2(N) +1) th bit to the (2 × LOG2(N)) th bit of the source data service bit sequence;
step S4: the second communication node removes the first 2 × LOG2(N) bits from the source data service bit sequence to obtain a remaining source data service bit sequence;
step S5: if the length of the residual information source data service bit sequence is less than or equal to 64, the second communication node uses a polarization code to perform channel coding on the residual information source data service bit sequence to obtain a channel data service bit sequence; if the length of the residual information source data service bit sequence is greater than 64 and less than or equal to 128, the second communication node uses a low-density parity check code to perform channel coding on the residual information source data service bit sequence to obtain a channel data service bit sequence; if the length of the residual source data service bit sequence is greater than 128, the second communication node performs channel coding on the residual source data service bit sequence by using mixed coding of a polarization code and a low-density parity check code to obtain a channel data service bit sequence, wherein the mixed coding of the polarization code and the low-density parity check code means that the first 64 bits in the residual source data service bit sequence are coded by using the polarization code, and the rest bits are coded by using the low-density parity check code;
step S6: the second communication node randomly selects a candidate access sequence from the candidate access sequence group, sends the candidate access sequence, and transmits the channel data service bit sequence to the first communication node by using the candidate data resource;
step S7: if the first communication node successfully receives the information source data service bit sequence, sending feedback success information to a second communication node; and if the first communication node fails to successfully receive the source data service bit sequence, feeding no information back to the second communication node, dividing the source data service bit sequence into a plurality of 32-long bit sequences by the second communication node, repeating each 32-long bit sequence once to form a 64-long bit sequence, and retransmitting the 64-long bit sequence according to the manner from the step S1 to the step S6.
The first communication node is a base station, and the second communication node is a terminal.
Example 2: on the basis of embodiment 1, the number of subcarriers included in the candidate data resource is 3 × 512, and this value is determined after analysis based on the characteristics of the physical network data packet, and can be applied to more than 90% of data structures of the internet of things.
Example 3: on the basis of embodiment 2, 1/3 subcarriers of the subcarriers included in the candidate data resources are used for transmitting demodulation reference signals. Generally, a base station can perform channel estimation by using an access sequence sent by a terminal, so as to demodulate uplink data sent by the terminal, wherein the advantage of adding a demodulation pilot frequency is to improve the channel estimation precision of service data with a specific length which needs to be mainly protected, so as to improve the transmission success rate of the service data with the length.
Example 4: based on embodiment 3, the subcarriers for transmitting the demodulation reference signals are uniformly distributed in 3 × 512 subcarriers included in the candidate data resources. The advantage of this is that the base station can obtain the channel information of the resource used by the terminal to transmit data relatively accurately, and the probability of data receiving power is increased.
Example 5: on the basis of the embodiment 1, the code rate adopted when the source data service bit sequence is subjected to channel coding is less than or equal to 1/2. The purpose of this requirement is to ensure that the base station can successfully decode the uplink data transmitted by the terminals even when data transmission collisions occur between the terminals, by means of an extremely low code rate.
Example 6: on the basis of embodiment 1, if the length of the channel data traffic bit sequence is not greater than 64, the second communication node transmits 1 candidate access sequence using a time-frequency resource prior to the candidate data resource in time. The purpose of this is that, when the source bit length of the terminal is small, even if the access sequence fails to receive the access sequence due to low transmission energy, and the base station cannot decode the related data, the influence on the spectrum efficiency of the system is small.
Example 7: on the basis of embodiment 1, if the length of the channel data traffic bit sequence is greater than 64 and equal to or less than 128, the second communication node repeatedly transmits 2 candidate access sequences in time using a time-frequency resource prior to the candidate data resource. The purpose of this is that when the source bit length of the terminal is moderate, the energy of the base station for receiving the access sequence is increased in a mode of repeatedly transmitting the access sequence as much as possible, the probability of successfully receiving the access sequence is increased, and the probability of successfully receiving data by the base station is increased.
Example 8: on the basis of embodiment 1, if the length of the channel data traffic bit sequence is greater than or equal to 128, the second communication node repeatedly transmits 2 candidate access sequences in time by using time-frequency resources located on both sides of the candidate data resource. The purpose of this is that when the source bit length of the terminal is moderate, the energy of the base station for receiving the access sequence is increased in a mode of repeatedly transmitting the access sequence as much as possible, the probability of successfully receiving the access sequence is increased, and the probability of successfully receiving data by the base station is increased.
Example 9: on the basis of embodiment 1, the transmission power at each subcarrier at which the second communication node transmits the candidate access sequence is 6dB higher than the transmission power at each subcarrier at which the channel data traffic bit sequence is transmitted. The reason for this is that the data service bits have coding gain, the access sequence does not have any coding gain, and the access sequence has a decisive influence on the success or failure of receiving the data service, so the success rate of receiving the uplink data service by the base station is improved by increasing the transmission power of the access sequence.
Example 10: on the basis of embodiment 1, if the second communication node does not receive the reception success feedback information of the first communication node within 10ms of the transmission of the channel data traffic bit sequence, the second communication node determines two candidate data resources using the first 2 × LOG2(N) bits of the channel data traffic bit sequence, and the second communication node retransmits the channel data traffic bit sequence using the two candidate data resources. This has the advantage of obtaining frequency diversity gain by increasing the transmission resources as much as possible, thereby increasing the probability of successful data reception.
The invention also discloses an information sending system in the Internet of things, which comprises the following components: memory, a processor and a computer program stored on the memory, the computer program being configured to carry out the steps of the method of the invention when called by the processor.
The invention also discloses a computer-readable storage medium storing a computer program configured to, when invoked by a processor, implement the steps of the method of the invention.
The invention has the beneficial effects that: compared with the prior art, the method and the device provided by the invention have the advantages that the problem of poor spectrum efficiency in the existing Internet of things is solved, the spectrum efficiency of the Internet of things system is improved, and the control overhead is reduced.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
