It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1a is a flowchart of a communication data scheduling processing method in an embodiment of the present invention, where this embodiment is applicable to a situation where communication data scheduling processing is performed in a multi-level node network, and the method may be executed by a communication data scheduling processing apparatus provided in an embodiment of the present invention, and the apparatus may be implemented in a software and/or hardware manner, and may be generally integrated into a computer device. As shown in fig. 1a, the method of this embodiment specifically includes:

in the communication network of the embodiment of the invention, the physical channel for transmitting data comprises: physical Sidelink Shared Channel (psch): a channel for carrying data; the physical layer processing mechanisms such as encoding, rate matching, and interleaving are the same as for the end-to-end (D2D); physical downlink Control CHannel (PSCCH): channels for carrying control information, such as Scheduling Assignment Signaling (SA); the physical layer processing mechanisms such as coding, rate matching, interleaving and the like are the same as D2D; physical Broadcast Channel (PSBCH): for synchronous control and regulation. The PSCCH is used to indicate information such as a time-frequency domain resource location, a modulation coding scheme, and a receiving target identification Information (ID) targeted by the PSCCH for transmission of the PSCCH, and the PSCCH is used to carry data.

Also, the types of Signals transmitted include Demodulation Reference Signals (DMRS), and Synchronization Signals (SS). The DMRS is transmitted together with the psch, PSCCH, and is used for demodulation of the channels. The SS includes Primary and Secondary Synchronization Signals (PSSS) and SSSS. PSSS is SideLink main synchronous signal, SSSS is SideLink auxiliary synchronous signal. The PSSS and SSSS may obtain cell IDs, which are divided into two sets: id _ net and id _ oon. PSSS generation is the same as D2D, SSSS employs the SS sequence of LTE subframe 5.

In a specific example, the embodiment of the present invention adopts a Long Term Evolution Vehicle networking (LTE-V) technology, which is an Evolution technology oriented to intelligent transportation and Vehicle networking applications and based on a 4G LTE system. The LTE-V can support the communication requirements of large bandwidth and large coverage by means of the existing cellular network; the LTE-V can also be independent of a cellular network, so that low-delay and high-reliability direct communication between vehicles and surrounding environment nodes is realized, and the driving safety requirements are met. LTE-V can only use Half duplex operation (HD) on the PC5 interface. The DMRS transmission of LTE-V is the same as that of an LTE Uplink shared Physical CHannel (PUSCH), the bandwidth of the transmission CHannel is consistent in the frequency domain, the whole bandwidth is occupied at most, and the time domain is encrypted and designed to support high-speed movement.

When data transmission is performed in a physical channel, the time domain structure is specifically as shown in fig. 1 b: the adopted subframe structure comprises 4 DMRS symbols in a PSCCH or PSSCH subframe, and the other symbols are data symbols. The 1 st symbol (number 0) of the data symbols is used for Automatic Gain Control (AGC) adjustment of the subframe, and the last symbol is not transmitted as a guard interval.

The frequency domain structure is specifically shown in fig. 1c and fig. 1 d: fig. 1c is a schematic diagram of resource pool configuration using an adjacent band transmission method, and fig. 1d is a schematic diagram of resource pool configuration using a non-adjacent band transmission method. The time domain resource of the resource pool in fig. 1c and fig. 1d is a time slice occupied by one symbol.

In the adjacent band transmission mode:

resource Blocks of PSCCH and PSCCH are adjacent (Adjacency of PSCCH and psch Resource Blocks): and the data transmission mode is used for indicating whether the SA and the data (data) adopt the adjacent band transmission mode.

If the transmission mode of the adjacent band is adopted, in the Resource pool configuration of the adjacent band, the Resource of the SA is always located in the lowest 2 PRBs of a Physical Resource Block (PRB) of one subchannel, and there is only one SA channel in each subchannel.

Specifically, as shown in fig. 1c, the parameters included in the resource pool configuration are as follows:

size of Subchannel (Subchannel size): configurable parameters are {5,6,10,15,20,25,50,75,100 }; number of subchannels (Number of subchannels): the configurable parameters are {1,3,5,8,10,15,20 }; RB index for subchannel start (Starting RB of subcarriers): take the integer from {0, …,99 }.

If a non-adjacent band transmission mode is adopted, the resources of the SA and the sub-channels have one-to-one correspondence, and the number of the corresponding SA channels is the same as that of the sub-channels. Specifically, as shown in fig. 1d, the parameters included in the resource pool configuration are as follows:

subchannel size: the configurable parameters are {4,5,6,8,9,10,12,15,16,18,20,30,48,72,96 }; number of subchannels: the configurable parameters are {1,3,5,8,10,15,20 }; starting RB of subchannels: taking an integer from {0, …,99 }; starting RB index of PSCCH resource (Starting RB of PSCCH pool): take an integer from 0, …,99, this parameter may not be needed if in the adjacent band transmission mode.

S110, in the physical control channel, obtaining target sending device information of at least one target sending device.

The physical control channel is used for transmitting control information, and is illustratively a PSCCH of a communication network based on LTE-V technology. The control information is used by the receiving end to determine information such as a time-frequency domain resource position, a modulation and coding scheme of corresponding PSSCH transmission, and receiving target identification Information (ID) aimed at by the PSSCH.

The computer equipment for realizing the communication data scheduling processing method is LTE-V receiving equipment. The target sending equipment is LTE-V sending equipment. Wherein, the receiving device is usually a vehicle-mounted terminal. The target transmitting device may include at least one of: vehicle terminals, roadside facility terminals, user terminals, and networks (e.g., local area networks), among others. The roadside facility terminal may include a traffic light terminal, a guideboard terminal or a roadside building terminal, etc.

Optionally, the target sending device includes a node in the internet of vehicles, and the node includes a traffic light device, a vehicle device, or a user device.

The target sending equipment and the target receiving equipment are nodes in the Internet of vehicles. In the internet of vehicles, one receiving device can simultaneously receive signals transmitted by a plurality of target transmitting devices. The node may be a traffic light device, a vehicle device, or a user device. The traffic light equipment can provide traffic light position information and signal light information, and the receiving equipment is convenient to avoid obstacles to the traffic light equipment, drive and brake according to traffic light signals, or plan routes according to a plurality of traffic light signals and the like. The vehicle equipment can provide position information, running state information and the like of the vehicle, and the receiving equipment can conveniently carry out obstacle avoidance, running state adjustment, route planning and the like on the vehicle equipment. The user equipment can provide the self position and the self moving state (including a static state and a moving state) of the user, and the receiving equipment can conveniently avoid obstacles for passers-by. Typically, the receiving device is a vehicular device.

By configuring the target sending equipment as the vehicle networking node and configuring the vehicle networking node to comprise various types of equipment, the diversity of data of the target sending equipment can be increased, and the application scenes of receiving equipment in the vehicle networking can be increased.

The transmission apparatus information is used to determine the processing order. The sending device information may refer to sending device associated data, and may include at least one of the following: identification information of the transmitting device (or name of the vehicle, user name, or name of the roadside device, etc.), type of the transmitting device, attribute information of the transmitting device (such as brand of the vehicle, gender of the user, or function of the roadside device), configuration information of the transmitting device (such as pre-configured priority of the transmitting device), and the like. Wherein the transmitting device information may be extracted from the control information.

Optionally, the obtaining, in the physical control channel, target sending device information of at least one target sending device includes: carrying out channel estimation, demodulation and decoding on data corresponding to a physical control channel in effective symbol data of a subframe; and if the decoding result is correct, acquiring target sending equipment information of at least one target sending equipment extracted from the correct decoding result.

The receiving device processes data in units of subframes, that is, the receiving device processes one subframe and continues to process the next subframe. A subframe typically comprises 14 symbols, as shown in fig. 1b, where there are two first and two last symbols not used for transmitting data. The valid symbol data is the middle 12 symbols. The valid symbol data is a symbol for carrying valid information, for example, carrying control information and carrying transmission data. The data corresponding to the physical control channel may refer to control information carried by the physical control channel, and the data corresponding to the physical control channel includes control information carried by a plurality of sub-channels or includes control information corresponding to a plurality of target transmission devices.

The decoding result is correct, which indicates that correct control information can be obtained, so that channel estimation, demodulation and decoding can be performed on corresponding transmission data according to the correct control information. The correct decoding result comprises the sending equipment information, and the sending equipment information can be directly extracted from the decoding result. And if the decoding result is wrong, recording the target sending equipment with the wrong decoding so as to combine the data according to the retransmitted data to form a correct decoding result, or directly discarding the data.

It should be noted that, in the physical shared channel, acquiring transmission data corresponding to each target sending device includes: and extracting data corresponding to the physical control channel from the effective symbol data of the subframe, and acquiring transmission data corresponding to each target sending device.

By processing the data by taking the subframe as a unit, effective symbol data can be quickly acquired, and the sending equipment information is extracted, so that the transmission data of each target sending equipment is acquired for scheduling, data accumulation is reduced, and the communication data analysis efficiency can be improved.

And S120, determining a data processing sequence corresponding to each target sending device according to the information of each target sending device.

The data processing sequence is used for scheduling data of different sending devices. The data processing order may refer to an order in which data corresponding to different target transmission devices are processed. The data corresponding to the target sending device is data carried by a sub-channel corresponding to the target sending device in the physical shared channel. In fact, one target sending device may correspond to multiple sub-channels in the physical shared channel, that is, data carried by the corresponding multiple sub-channels is data sent by the target sending device. For example, each target sending device may be divided according to the sending device information, and the priority of each packet may be determined, and meanwhile, the group may continue to be divided according to the sending device information, and the priority of each classification may be determined, where the data processing order with the higher priority is before and the data processing order with the lower priority is after.

Optionally, the determining, according to the information of each target sending device, a data processing order corresponding to each target sending device includes: dividing each target sending device into a sending device to be combined for retransmission and a sending device to be combined for non-retransmission according to retransmission identification information included in each target sending device information and a primary translation result type corresponding to each sending device, and determining a data processing sequence corresponding to each target sending device, wherein the data processing sequence of the sending device to be combined for retransmission is before the data processing sequence of the sending device to be combined for non-retransmission; in the target sending devices of the same type, determining a data processing order corresponding to each target sending device of the same type according to the scheduling indication priority included in the information of each target sending device, wherein the data processing order of the sending device with the higher priority is prior to the data processing order of the sending device with the lower priority; and in the target sending devices with the same priority, determining a data processing order corresponding to each target sending device with the same priority according to the signal-to-noise ratio included by the information of each target sending device, wherein the data processing order of the sending device with the high signal-to-noise ratio is before the data processing order of the sending device with the low signal-to-noise ratio.

The retransmission identification information is used to determine whether a data packet (including control information and transmission data) in a sub-channel corresponding to the sending device is a retransmission data packet. In general, the types of data packets may include an initial transmission data packet and a retransmission data packet. In order to avoid the situation that the initial transmission data packet has packet loss, the transmitting device may retransmit the data packet, where the retransmitted data packet is a retransmission data packet, and the retransmission data packet is used by the receiving device to obtain an accurate data packet without data loss, so as to improve the data transmission accuracy. The retransmission identification information may include an initial transmission and no retransmission identification, an initial transmission and retransmission identification, and a retransmission identification. The initial transmission and no retransmission identifier is used for identifying the current data packet as the initial transmission data packet, and the corresponding transmitting device does not transmit the corresponding retransmission data packet. The initial transmission is used for identifying that the current data packet is the initial transmission data packet, and the corresponding sending device sends the corresponding retransmission data packet, for example, the retransmission data packet may be sent in the next subframe or the nth subframe. The retransmission identifier is used for identifying the current data packet as a retransmission data packet. The initial transmission decoding result type is used for judging whether the decoding result of the initial transmission data packet sent by the sending equipment is correct or not. Usually, the retransmitted data packet with the initial decoding result type being the correct decoding result may not need to be processed further, and may be discarded.

And preferentially judging the type of the target sending equipment, and determining different types of data processing sequences according to the type of the target sending equipment. Classifying each target sending device according to the retransmission identification information and the type of the initial translation result, wherein the type may include: retransmitting the type of the transmission device to be combined and the type of the transmission device not to be combined. And determining the type of the target sending equipment marked with the retransmission identifier and corresponding to the retransmission data packet corresponding to the initial decoding result as the type of the retransmission to-be-combined sending equipment. And the other types are the types of the retransmission to-be-combined sending equipment and the types of the non-retransmission to-be-combined sending equipment. For example, the target sending device corresponding to the initial transmission data packet which is initially transmitted without the retransmission identifier and initially transmitted with the retransmission identifier, and the target sending device corresponding to the retransmission data packet which is retransmitted with the retransmission identifier and the initial decoding result type being the correct decoding result, are the non-retransmission to-be-combined sending device types. The advantage of this arrangement is that data which has not been decoded correctly in history can be processed, the fault tolerance of communication network to communication data can be improved, and the processing of data packet with decoding error can be reduced.

Secondly, in the same type, the target sending equipment is continuously divided according to the scheduling indication priority, and the data processing sequence is determined according to the division result. In a plurality of target sending devices of the same type, the target sending devices of the same type are divided according to the scheduling indication priority, and the data processing sequence is determined according to the division result, wherein the data processing sequence with high priority is more advanced, and the data processing sequence with low priority is more advanced. The scheduling indication priority may refer to a priority included in the SA signaling, which is typically a priority pre-configured according to any index (which may be configured as needed), for example, a priority pre-configured according to the type of the target transmission device. Illustratively, the user device has a priority of 3, the traffic light device has a priority of 2, and the vehicle device has a priority of 1. This has the advantage that critical signals, or signals of higher importance, can be handled preferentially, and emergency events can be responded to, improving the reliability of the receiving device, and improving the transmission reliability of the communication network.

And thirdly, in a plurality of target sending devices with the same priority, dividing the target sending devices with the same priority according to Signal to Noise Ratio (SNR), and determining a data processing order according to a dividing result, wherein the data processing order with high SNR is the front, and the data processing order with low SNR is the back. The signal-to-noise ratio may refer to a communication quality of a channel between the receiving device and the target transmitting device, where the signal-to-noise ratio may be determined according to a channel estimation result. The advantage of this arrangement is that the data packet with poor signal quality can be processed with priority, and the data packet with poor signal quality can be post-processed, so that the influence caused by the error of the data packet with poor signal quality can be reduced, and the reliability of the communication network can be improved.

In fact, in the case where the processing capability of the receiving device is limited, the priority scheduling process may retransmit the combined target transmitting device, if there is capability, the target transmitting device with high priority is scheduled, and in the case of the same priority, the target transmitting device with high signal-to-noise ratio of the PSCCH channel is scheduled preferentially.

By configuring the type, scheduling indication priority and signal-to-noise ratio of the target sending equipment and sequentially determining the data processing sequence of each target sending equipment according to the parameters, unnecessary processing overhead can be avoided under the condition that the processing capacity is limited, the limited processing capacity can be used for processing transmission data sent by the key target sending equipment, and the reliability of the system is improved.

S130, in the physical shared channel, obtaining transmission data corresponding to each target sending device.

The physical shared channel is used for transmitting data, and is exemplarily a PSSCH of a communication network based on LTE-V technology. The transmission data may refer to data carried in a physical shared channel, and the transmission data is used for a receiving device to perform scheduling processing to obtain valid data and perform processing operation. For example, the processing operation may include performing an obstacle avoidance operation on the target transmission device, an adjustment operation of the traveling direction and the traveling speed of the reception device, a planning operation of the traveling route of the reception device, a generation operation of the warning prompt of the target transmission device, and the like.

S140, scheduling the transmission data corresponding to each target sending device according to each data processing order.

The data processing order specifies a processing order in which the receiving apparatus processes the data transmitted by each target transmitting apparatus. The scheduling process may include the receiving device performing channel estimation, equalization demodulation, channel decoding, and the like on the transmission data. Specifically, channel estimation may refer to estimating channel transmission characteristics using pilot symbols. Equalization demodulation, including equalization and demodulation, wherein equalization may refer to compensating signal distortion caused by non-ideal of a transmission channel by using a channel estimation result, and simultaneously realizing maximum ratio combination of multi-antenna receiving signals. Demodulation may refer to Inverse Discrete Fourier Transform (IDFT) of the signal from the equalization process to Transform the frequency domain signal to the time domain. Then, according to different modulation modes, the time domain signals are transformed into serial demodulation data through corresponding constellation demapping. Channel decoding may refer to descrambling, de-channel interleaving, decoding, etc. of data.

The embodiment of the invention extracts the data in the physical control channel to obtain the target sending equipment information of at least one target sending equipment, determines the data processing sequence of each target sending equipment according to the information of each sending equipment, and processes the transmission data carried in the channel corresponding to each target sending equipment according to the processing sequence, thereby solving the problem of resource waste caused by demodulating and decoding the transmission data of each sending end in the channel in the prior art, carrying out sequential scheduling processing on the transmission data of each sending end according to the processing sequence, reasonably configuring the scheduling resources of channel data, improving the utilization rate of the scheduling resources and improving the reliability of a communication network.

And carrying out channel estimation, equalization and demodulation, channel decoding and the like on a bearing signal of the effective symbol data of the subframe in a physical control channel, and acquiring the sending equipment information of sending equipment associated with the subframe. For example, as shown in fig. 1c and fig. 1d, channel estimation, equalization demodulation, channel decoding, and the like are performed on a channel where scheduling assignment signaling (SA signaling) is located, and transmission device information of at least one transmission device is obtained.

S220, determining a bad point sending device in each sending device according to the information of each target sending device, and removing the bad point sending device.

The bad point sending device is used for eliminating the transmission data related to the bad point sending device from the target sending device and not analyzing the transmission data. Among the transmission devices associated with the subframes, the bad point transmission device may refer to a transmission device that does not perform scheduling processing. And the rejection is used for screening the sending equipment and screening the sending equipment with the bad points.

For the psch channel, since the last symbol of each subframe of the transmitting device is used as a GAP (GAP) for transmit-receive switching, the first symbol of the receiving end is used as AGC capture, after two symbols are punctured, when some Modulation and Coding Scheme (MCS) and RB number configuration are combined, even if a corresponding Transport Block Size (TBS) code Block is decoded correctly under an ideal channel condition. Such a device can be searched according to the information of the sending device, subsequent scheduling processing of transmission data is not performed, operations such as channel estimation and equalization demodulation before decoding errors are performed are avoided, and resource waste can be avoided.

Optionally, the determining, in each of the sending devices, a bad point sending device according to the information of each of the target sending devices includes: determining mapping relation of the bad point sending equipment matched with the information of each target sending equipment according to version information, transmission times and transmission formats of a physical layer protocol included by the information of each target sending equipment; and determining the bad point sending equipment in each sending equipment according to the modulation and coding strategy identification included by each target sending equipment information and the mapping relation of the matched bad point sending equipment.

The mapping relation table between the modulation and coding strategy identified bad point sending devices can be configured in advance, and the mapping relation between the version information, the transmission times and the transmission format of the physical layer protocol and the mapping relation table can be configured. Therefore, the mapping relation table can be inquired through the version information, the transmission times and the transmission format of the physical layer protocol, and the bad point sending equipment matched with the modulation coding strategy identification is inquired in the inquired mapping relation table. The transmission times of the initial transmission without the retransmission identifier is a single transmission, the initial transmission with the retransmission identifier and two transmissions of the retransmission identifier, and generally, the transmission times includes a single transmission or two transmissions. The version information, transmission times, transmission format and modulation and coding strategy identification of the physical layer protocol are all data included in the SA signaling. The mapping relationship is determined by statistical experiments.

By configuring the mapping relation between the modulation and coding strategy identifier and the bad point sending equipment and the relation between the version information, the transmission times and the transmission format of the physical layer protocol and the mapping relation, the bad point sending equipment can be determined according to the pre-configured relation, and the determining efficiency and the accuracy of the bad point sending equipment can be improved.

Optionally, the mapping relationship of the bad point sending device includes: a dead pixel mapping table and a dead pixel identification range; determining, in each of the sending devices, a bad point sending device according to a modulation and coding policy identifier included in the information of each of the target sending devices and the mapping relationship between the matched bad point sending devices, including: in a dead pixel mapping table matched with the information of each target sending device, according to a modulation and coding strategy identifier included in the information of each target sending device, inquiring dead pixel resource block identifier information corresponding to the information of each target sending device; if the resource block identification information included in the sending equipment information of the sending equipment is matched with the corresponding bad point resource block identification information, determining that the sending equipment is bad point sending equipment; acquiring modulation and coding strategy identifications corresponding to the information of each target sending device in a dead pixel identification range matched with the information of each target sending device; and if the modulation and coding strategy identification included in the sending equipment information of the sending equipment is determined to be matched with the corresponding bad point identification range, determining that the sending equipment is the bad point sending equipment.

The dead pixel mapping table stores the mapping relation between the modulation and coding strategy identification and the dead pixel resource block identification information, and is used for inquiring the matched dead pixel resource block identification information according to the modulation and coding strategy identification. The identification information of the bad point resource block is the identification information of the resource block corresponding to the bad point sending equipment. In general, in some resource blocks where the modulation corresponds to the coding strategy identification, the decoding cannot be correctly performed even in the ideal channel situation. The resource blocks corresponding to the modulation and coding strategy identifications which cannot be decoded correctly can be configured as a dead-pixel mapping table.

The resource block identification information included in the sending device information of the sending device is matched with the bad point resource block identification information corresponding to the sending device, that is, the sending device carries at least one resource block of transmission data in the sub-frame or the effective symbol data, and belongs to the range of the bad point resource block corresponding to the sending device, and then the sending device is determined to be the bad point sending device. As shown in fig. 2b, the at least one resource block for carrying transmission data and control information in the subframe or the valid symbol data by the sending device 0 may refer to 10 resource blocks carrying scheduling allocation signaling 0 and data 0, and the identifier of the resource block may be 1-10, if the range of the bad point resource block includes 9, 12, and 15, the resource block identifier information included in the sending device information of the sending device matches with the bad point resource block identifier information corresponding to the sending device, and the sending device is a bad point sending device.

The dead-spot identification range may refer to a set of modulation and coding strategy identifications corresponding to the dead-spot transmitting device. The modulation and coding strategy identifier included in the sending device information of the sending device is matched with the corresponding dead pixel identifier range, which may mean that the modulation and coding strategy identifier belongs to the dead pixel identifier range.

According to the version information, the transmission times and the transmission format of the physical layer protocol, whether the matching is the bad point mapping table or the bad point identification range is determined, different parameters are correspondingly selected for inquiring, and the sending equipment is determined.

Illustratively, the version information of the physical layer protocol is R14 version or R15 version, and the transmission format is 0; the number of transmissions indicated in the PSCCH channel decoding result is a single transmission.

The mapping relation inquired at this time comprises a first dead pixel mapping table and a first dead pixel identification range, wherein the first dead pixel mapping table is the mapping relation between the modulation and coding strategy identification and the dead pixel resource block identification information in the range of 0-20. The range of the first dead pixel mark is 21-28. If the modulation and coding strategy identification of the sending equipment belongs to the range of 0-20, inquiring identification information of a dead pixel resource block in a first dead pixel mapping table according to the modulation and coding strategy identification of the sending equipment, and if the identification information of the resource block corresponding to the sending equipment is the same as any one of the inquired identification information of the dead pixel resource block, the sending equipment is dead pixel sending equipment; and if the modulation and coding strategy identification of the sending equipment belongs to the range of 21-28, the sending equipment is a bad point sending equipment.

For another example, the version information of the physical layer protocol is the R14 version or the R15 version, and the transmission format is 0; the number of transmissions indicated in the PSCCH channel decoding result is two transmissions.

If the current data packet is the initial transmission data packet and the retransmission data packet, the inquired mapping relation comprises a second bad point mapping table. The second bad point mapping table is a mapping relation between the modulation and coding strategy identification and the bad point resource block identification information in the range of 0-28.
