Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
In the description of the present invention, unless otherwise specifically limited, terms such as set, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention by combining the specific contents of the technical solutions.
Referring to fig. 1, a data transmission method according to an embodiment of a first aspect of the present invention includes:
and step S100, acquiring a synchronization advance.
The synchronization advance may be a delay value measured by the mobile station, and the delay refers to a time required for transmitting a packet or packet from one end of a network to another end. Because the mobile station and the base station always have a certain physical distance, when the mobile station and the base station communicate, a time delay of signal transmission is caused, and if no measures are taken, the time delay can cause that a message sent by the mobile station on the current time slot and received by the base station on the next time slot are overlapped, so that the information cannot be correctly decoded. Therefore, the synchronization advance can be set to achieve the purpose of synchronization. Optionally, the synchronization lead may be configured according to specific requirements such as an actual channel environment, and the like, so as to enable an uplink packet of the terminal device to reach the base station at a desired time, estimate a radio frequency transmission delay caused by a distance, and send out a data packet at a corresponding time in advance, thereby ensuring synchronization performance.
And step S110, setting a preset time delay jitter according to the synchronous advance.
The preset delay jitter may be a preset delay variation. Optionally, after the synchronization lead is determined, a maximum value of a preset delay jitter of each User Equipment (UE) may be obtained, that is, a range of the preset delay jitter may be set according to the synchronization lead, and then the preset delay jitter may be randomly selected according to the range of the preset delay jitter to obtain the preset delay jitter.
Step S120, linear frequency offset is obtained.
The linear frequency offset may be frequency offset when multiple nodes perform cooperative transmission, and the frequency offset is amplitude of frequency modulation wave frequency swing. Optionally, in consideration of the influence caused by the movement of the terminal device in the actual environment and the different movement speeds between different nodes, the performance of forwarding by multiple nodes may be changed, so that linear frequency offset may be introduced according to the movement speed, and frequency offset may be obtained when multiple nodes perform cooperative transmission, that is, the frequency offset amplitude in the data transmission process may be obtained according to the linear frequency offset. The linear frequency offset may include frequency offset of an internode crystal oscillator and Doppler frequency offset introduced by relative motion of nodes.
Step S130, configuring a data transmission mode based on the linear frequency offset, configuring a preset time delay jitter for the node if the linear frequency offset meets the threshold requirement, and performing data transmission according to the preset time delay jitter.
The data transmission mode may be a mode of data transmission on the node; the threshold requirement may be a fluctuation range requirement corresponding to the linear frequency offset. Optionally, the data transmission mode may be configured based on the size of the linear frequency offset, so that the node may perform data transmission according to a suitable data transmission mode, thereby ensuring that a stable forward gain exists when multiple nodes send the same data to one node at the same time. Optionally, if the linear frequency offset meets the threshold requirement, a data transmission mode may be configured for the node according to the preset delay jitter, for example, corresponding preset delay jitter may be configured for each node, so that a plurality of nodes may perform data transmission according to the preset delay jitter, cooperative transmission is implemented, and transmission between the plurality of nodes may not interfere with each other, which avoids mutual cancellation or performance loss of received signals due to randomness of signals between the plurality of nodes in the data transmission process, thereby ensuring that a stable forward gain exists when a plurality of nodes simultaneously transmit the same data to one node.
According to the data transmission method, the preset time delay jitter is set through the acquired synchronous lead, then the linear frequency offset can be acquired, finally the data transmission mode is configured based on the linear frequency offset, if the linear frequency offset meets the threshold requirement, the preset time delay jitter is configured for the node, and data transmission is carried out according to the preset time delay jitter, so that the failure probability of receiving signals can be reduced, the transmission performance of a system is enhanced, and the communication efficiency is improved.
In some embodiments of the present invention, if the linear frequency offset meets the threshold requirement, the method includes:
and acquiring a preset threshold value. The preset threshold may be a critical value corresponding to a preset linear frequency offset. Optionally, whether the linear frequency offset meets the threshold requirement may be determined by presetting a threshold. For example, assume that the preset threshold is P 0 Then can be according to P 0 To determine whether the linear frequency offset meets the threshold requirement.
And if the linear frequency offset is smaller than the preset threshold, the linear frequency offset meets the threshold requirement. Optionally, assume that the preset threshold is P 0 Assuming linear frequency offset of P 1 Suppose P 1 ＜P 0 Then P can be judged 1 The linear frequency deviation P can be judged because the linear frequency deviation P has small influence on communication transmission 1 The method meets the threshold requirement, namely when the linear frequency deviation is small, the moving speed of the terminal equipment is slow and is in a quasi-static state, and the method can be based on the P meeting the threshold requirement 1 The data transmission mode is configured to configure the preset time delay jitter for the nodes, so that stable forward gain exists when a plurality of nodes send the same data to one node at the same time, and the problem of unstable performance of a receiving end in multi-node cooperative transmission in a burst communication system is solved.
In some embodiments of the present invention, configuring a data transmission mode based on linear frequency offset comprises:
if the linear frequency deviation is larger than the preset threshold value, the linear frequency deviation does not accord withA threshold requirement. Optionally, assume that the preset threshold is P 0 Assuming linear frequency offset of P 2 Let P be 2 ＞P 0 Then P can be judged 2 The linear frequency deviation P can be judged because the linear frequency deviation P has larger influence on communication transmission 2 The threshold requirement is not met.
And configuring a preset period for the node, and transmitting data according to the preset period. Optionally, if the linear frequency offset does not meet the threshold requirement, a preset period may be configured for the node, so as to reduce the influence of the linear frequency offset on data transmission. For example, the size of the Midamble period inserted in the data frame can be adjusted, that is, the preset period is obtained, and then data transmission can be performed according to the adjusted preset period, so as to obtain a stable forward gain. The method has the advantages that the preset period is configured for the nodes through the large linear frequency deviation, then data transmission can be carried out according to the preset period, the complexity is low, and stable forward gain can be achieved when a plurality of nodes send the same data to one node simultaneously under the link characteristic of the ad hoc network.
In some embodiments of the present invention, acquiring the synchronization advance includes:
and acquiring the current transmission mode. The current transmission mode may be a transmission mode corresponding to the current line data transmission. Optionally, the current transmission mode may be a single-UE transmission mode (i.e., single device mode) or a multi-UE transmission mode (i.e., multi-device mode).
And acquiring the synchronous lead based on the current transmission mode, and acquiring a first synchronous lead if the current transmission mode is a single-equipment mode. The first synchronization lead is a synchronization lead corresponding to a single device mode, and the single device mode may be a single UE transmission mode. Optionally, different synchronization leads correspond to different current transmission modes, so that the current transmission mode can be obtained, and the synchronization lead is obtained according to the obtained current transmission mode. Therefore, if the current transmission mode is the single device mode, the synchronization advance during data transmission may be set as the first synchronization advance, and then the preset delay jitter may be set according to the first synchronization advance. The synchronization lead corresponding to the current transmission mode is obtained through the current transmission mode, if the current transmission mode is the single-device mode, the first synchronization lead corresponding to the single-device mode can be obtained, namely different synchronization leads are respectively determined according to different current modes, and the data transmission performance and efficiency can be improved.
In some embodiments of the present invention, acquiring the synchronization advance based on the current transmission mode further comprises:
and if the current transmission mode is the multi-equipment mode, acquiring a second synchronous lead. The second synchronization advance may be a synchronization advance corresponding to the multi-device mode; the multi-device mode may be a multi-UE transmission mode. Optionally, if the current transmission mode is the multi-device mode, the synchronization advance during data transmission may be set as a second synchronization advance, and then a preset period may be set according to the second synchronization advance. The synchronization lead corresponding to the current transmission mode is obtained through the current transmission mode, if the current transmission mode is the multi-device mode, the second synchronization lead corresponding to the multi-device mode can be obtained, namely different synchronization leads are respectively determined according to different current modes, and data transmission performance and efficiency can be improved.
Referring to fig. 2, in some embodiments of the present invention, setting a preset delay jitter according to a synchronization advance includes:
and step S200, obtaining a preset range corresponding to the preset time delay jitter according to the synchronous lead. The preset range may be a threshold range corresponding to the preset delay jitter. Optionally, the synchronization advance may be used as a maximum value corresponding to the preset delay jitter, that is, a preset range corresponding to the preset delay jitter may be obtained. For example, assume that the minimum value corresponding to the preset delay jitter is set as Y according to the requirement 0 Assuming that the synchronization lead is the first synchronization lead Y corresponding to the single device mode 1 Then the maximum value corresponding to the preset delay jitter can be obtained as Y 1 That is, the preset range corresponding to the preset time delay jitter is Y 0 ～Y 1 (ii) a For another example, assume that the minimum value corresponding to the preset delay jitter is set as Y according to the requirement 0 Assuming that the synchronization lead is the second synchronization lead Y corresponding to the multi-device mode 2 Then the maximum value corresponding to the preset delay jitter can be obtained as Y 2 That is, the preset range corresponding to the preset time delay jitter is Y 0 ～Y 2 。
Step S210, setting a preset delay jitter interval. The preset delay jitter interval may be a time interval of random delay jitter. Optionally, the preset delay jitter interval may be set according to the bandwidth size of the current transmission mode, where the preset delay jitter ranges under different bandwidths are the same, but the corresponding preset delay jitter intervals are different. For example, assuming that the current transmission mode is the single device mode, the preset delay jitter interval may be set to t according to the bandwidth of the single device mode 1 (ii) a For another example, if the current transmission mode is the multi-device mode, the preset delay jitter interval may be set to t according to the bandwidth of the multi-device mode 2 。
And step S220, selecting to obtain the preset time delay jitter according to the preset range and the preset time delay jitter interval. Optionally, the preset delay jitter may be obtained by selecting according to a preset range corresponding to the preset delay jitter and a preset delay jitter interval. For example, assume that the predetermined range is Y 0 ～Y 1 If the preset delay jitter interval is Δ J, the preset delay jitter may be obtained by dividing according to the preset range and the preset delay jitter interval, and then the preset delay jitter may be obtained by selecting from the preset delay jitter according to a requirement. The preset range can be obtained through the synchronous lead, the preset time delay jitter interval is set, then the preset time delay jitter can be obtained according to the preset range and the preset time delay jitter interval, the preset time delay jitter corresponding to the node can be obtained, the failure probability of receiving signals is reduced, and the cooperative transmission of a plurality of nodes is realized.
In some embodiments of the present invention, configuring a preset delay jitter for a node includes:
and adding preset time delay jitter to the data frame of the node. The data frame may be a frame encapsulating data to be transmitted by the node. The data frame may include three portions: frame header, data part, frame trailer. Optionally, a preset delay jitter may be added to a frame header portion of a data frame of the nodeFor example, assume that the experimental jitter is preset to be T 1 Assuming that the data frame of the node is a UE1 data frame, T may be set 1 And the frame header part added to the data frame of the UE1 enables a target host (or a base station) to correctly acquire the preset time delay jitter configured for the node, and improves the efficiency of data transmission.
