Description

Method and device for signal processing

This application claims priority from a Chinese patent application filed with the Chinese Patent Office on May 28, 2018, with application number 201810524732.9 and with the application name "Signal Processing Method and Device", the entire contents of which are incorporated herein by reference.

Technical field

The present application relates to the field of communications, and more particularly, to a method and apparatus for signal processing.

Background technique

In the future 5G communication system, with the rapid development of mobile communication, there are higher requirements in many aspects such as system capacity, instantaneous peak rate, spectrum efficiency, cell-edge user throughput, and delay. At present, coordinated multiple points (CoMP) communication can improve system performance whether it is uplink or downlink, especially to improve spectrum efficiency at the cell edge.

In multiple transmission and reception points (TRP), in order to enhance the reliability of transmission, a diversity scheme may be used between multiple TRPs to transmit data to edge users. For example, the network device uses one or more operations such as different hybrid automatic repeat request (HARQ) redundancy versions (RV), different scrambling modes, and the like to send the same data.

However, after the terminal device receives the data sent by the diversity, the data parsing and feedback method is still performed according to the data sent by the non-diversity, which will cause the problem of complex analysis and inaccurate feedback.

Summary of the Invention

This application provides a method and device for signal processing, which can improve system performance.

In a first aspect, a signal processing method is provided, and the method includes:

Receiving diversity indication information, where the diversity indication information is used to indicate that at least two data blocks received by the terminal device are transmitted in diversity by at least two network devices; the at least two data blocks include the same data;

Sending feedback information to at least one of the at least two network devices according to the diversity instruction information, the feedback information is used to indicate a parsing result, and the parsing result is parsed by the terminal device to at least two of the at least two data blocks Get a data block.

The terminal device receives the diversity instruction information, and the diversity instruction information indicates that the at least two data blocks received are at least two data blocks including the same data. The terminal device can analyze the at least two data blocks after knowing the transmission mode of the received data blocks. At least one data block of each data block obtains a parsing result, and sends the same feedback information to all network devices in the at least two network devices, so that the terminal device sends to each of the at least two network devices The same feedback information prevents network devices that send data blocks in the manner of diversity transmission from receiving different feedback information, thereby improving the accuracy of feedback. Or the terminal device sends feedback information to any one of the at least one network device, or the terminal device sends feedback information to some network devices in the at least one network device, thereby saving feedback overhead.

In some possible implementation manners, the receiving diversity indication information includes:

Receiving radio resource control RRC signaling, the RRC signaling includes a new field, the new field is used to carry the diversity indication information; or

Receiving media access control element MAC-CE signaling, the MAC-CE signaling includes a new field, the new field is used to carry the diversity indication information; or

Receive DCI signaling for downlink control information. The DCI signaling includes a new field, which is used to carry the diversity indication information.

The diversity indication information may be carried in a new field of the original signaling, that is, the network device informs the terminal device that at least two data blocks received by the at least two network devices are transmitted in diversity by an explicit indication. The diversity indication information may carry a new field in RRC signaling, MAC-CE signaling, or DCI signaling, thereby improving the flexibility of the network device indication.

In some possible implementation manners, the diversity indication information is a combination of a first modulation and coding strategy MCS index value and a new data indication NDI value of a first data block of the at least two data blocks.

The diversity indication information may be a combination of a first MCS index value and an NDI value of a certain data block (for example, a first data block) of the at least two data blocks. That is, the combination of the respective values of the first MCS index value and the NDI value is used to indicate that the received data block is transmitted in diversity, that is, the network device notifies the terminal device by an implicit indication method, thereby saving signaling overhead.

In some possible implementation manners, the first MCS index value is 29, 30, or 31, and the NDI value is 0 or 1.

In the embodiment of the present application, the scenario where the traditional solution is not used, that is, the NDI indicates initial transmission, and the MCS index value is any one of 29, 30, and 31 implicitly indicates the diversity transmission mode, thereby saving signaling overhead.

In some possible implementation manners, the diversity indication information is a combination of a first MCS index value of a first data block and a first redundant version RV value of the at least two data blocks.

In the embodiment of the present application, a data diversity transmission mode is indicated by releasing a function of an original MCS index value and an RV value.

In some possible implementation manners, the first MCS index value is 0, and the first RV value is 1 or 2.

The first MCS index value can be a value that is not frequently used in the traditional scheme, avoiding waste of idle resources, thereby improving resource utilization.

In some possible implementation manners, the first MSC index value and the first RV value are: using the parameters corresponding to the first RV value and the first MSC index value to decode the first data block, The bit rate is less than or equal to a preset decoding rate, and parameters corresponding to the first MCS index value include a modulation order and a transmission bit rate.

In the case that multiple TRPs use diversity to send data blocks to terminal equipment, terminal equipment and network equipment can agree that the network equipment can be configured to use as much as possible the RV value and MCS index in the instructions that parse the corresponding data block with a lower decoding rate The combination of values indicates the diversity transmission method, that is, the data block is decoded with the instruction information with a higher decoding rate, and the combination of the RV value and the MCS index value in the instruction information with a lower decoding rate indicates the diversity transmission method. Improve the decoding rate, and then further improve the system performance.

In some possible implementation manners, a transmission code rate corresponding to the first MCS index value is greater than or equal to a preset transmission code rate, and the first RV value is 1 or 2.

When the RV value is 1 or 2, and when the code rate corresponding to the MCS value is greater than or equal to the preset transmission code rate, the accuracy of decoding the data block is low. The combination of the RV value and the MCS index value in the instruction information with a lower decoding rate for the corresponding data block is used to indicate the diversity transmission mode, that is, the instruction information with a higher decoding rate is used to decode the data block and decode. The combination of the RV value and the MCS index value in the indication information with a lower rate indicates the diversity transmission method to improve the decoding rate and further improve the system performance.

In some possible implementation manners, the method further includes:

Determining the RV value for parsing the first data block according to the RV value for parsing the second data block of the at least two data blocks.

In this way, when the diversity transmission mode is implicitly indicated by a parameter in the indication information (for example, the indication information used to parse the first data block), the first data block can still be parsed, which further improves system performance.

In some possible implementation manners, in a case where the diversity transmission mode is implicitly indicated by a parameter in the indication information (for example, the indication information used to parse the first data block), the terminal device and the network device may agree in advance to fix these. The parameter value is used to parse the data block.

In some possible implementation manners, the RV value used to parse the second data block is the same as the RV value used to parse the first data block.

In some possible implementation manners, the RV value used to parse the second data block of the at least two data blocks and the RV value used to parse the first data block satisfy the following relationship:

RV1 = mod ((RV2 + N), M), where RV2 is the RV value used to parse the second data block, RV1 is the RV value used to parse the first data block, and M, N are pre- Set a positive integer.

In some possible implementation manners, the diversity indication information and the indication information used to parse a second data block of the at least two data blocks are carried in a same DCI signaling.

Network devices can negotiate to carry diversity indication information and indication information for parsing the second data block through a DCI signaling (for example, the first DCI signaling), so that the terminal device can determine the diversity instruction information and It is used to parse the indication information of the second data block, thereby saving the signaling overhead of the network device.

In some possible implementation manners, the diversity indication information and the indication information used to parse the second data block of the at least two data blocks are carried in different DCI signaling, respectively.

Network devices can negotiate to carry diversity instruction information and instructions for parsing the first data block through the first DCI, and carry instruction information for parsing the second data block through the second DCI signaling, thereby improving network device transmission Flexibility to parse data block instructions.

In some possible implementation manners, if the terminal device parses the at least two data blocks and at least one data block of the at least two data blocks is successfully parsed, the parsing result is that the analysis is successful; the terminal device If the parsing of the at least two data blocks fails, or the parsing of the first data block and the second data block fails, the parsing result is a parsing failure. In other words, the parsing result is caused by the terminal device. It is obtained by parsing the first data block and the second data block.

When the terminal device parses the at least two data blocks, when one data block is successfully parsed, the analysis result may be that the analysis is successful. In other words, when the terminal device successfully parses one data block, the terminal device may not parse other data blocks, thereby saving the processing time and power consumption of the data block by the terminal device. Alternatively, the terminal device analyzes the first data block and the second data block jointly to obtain an analysis result according to the instruction information for analyzing the first data and the instruction information for analyzing the second data. If the joint parsing is successful, the parsing result is parsing success; if the joint parsing fails, the parsing result is parsing failure.

In a second aspect, a method for signal processing is provided. The method includes:

Sending data blocks to the terminal device;

Sending diversity instruction information to the terminal device to indicate to the terminal device that the sent data block is sent in diversity by at least two network devices; the data block includes the same data as the data blocks sent by other network devices.

The network device sends a data block and diversity indication information, where the diversity indication information indicates that the sent data block is diversity-transmitted by at least two network devices, and the terminal device can analyze the at least two blocks after learning the transmission mode of the received data block. At least one data block of each data block obtains a parsing result, and sends the same feedback information to all network devices in the at least two network devices, so that the terminal device sends to each of the at least two network devices The same feedback information prevents network devices that send data blocks in the manner of diversity transmission from receiving different feedback information, thereby improving the accuracy of feedback. Or the terminal device sends feedback information to any one of the at least one network device, thereby saving feedback overhead. Or the terminal device sends feedback information to some network devices in the at least one network device.

In some possible implementation manners, the method further includes:

Receive feedback information, the feedback information is used to instruct the terminal device to parse and analyze at least one of the at least two data blocks sent by the at least two network devices, and the feedback information is indicated by the terminal device according to the diversity instruction The message was sent.

When the terminal device sends feedback information to each network device that sends the data block, each network device can receive the feedback information. In a case where the terminal device sends feedback information to a part of network devices that send data blocks, the network device that receives the feedback information is one of the part of network devices.

In some possible implementation manners, the sending the diversity indication information includes:

Sending radio resource control RRC signaling, the RRC signaling includes a new field, which is used to carry the diversity indication information; or

Sending MAC-CE signaling of the media access control control element, the MAC-CE signaling includes a new field, the new field is used to carry the diversity indication information; or

Sending downlink control information DCI signaling, the DCI signaling includes a new field, which is used to carry the diversity indication information.

In some possible implementation manners, the diversity indication information is a combination of a first MCS index value and an NDI value of a first data block in the at least two data blocks.

The diversity indication information may be a combination of a first MCS index value and an NDI value of a certain data block (for example, a first data block) of at least two data blocks sent by the at least two network devices. In other words, the combination of the respective values of the first MCS index value and the NDI value is used to indicate that the data block received by the terminal device is transmitted in diversity, that is, the network device notifies the terminal device by an implicit indication method, thereby saving signaling overhead. .

In the case that multiple TRPs use diversity to send data blocks to terminal equipment, terminal equipment and network equipment can agree that the network equipment can be configured to use as much as possible the RV value and MCS index in the instructions that parse the corresponding data block with a lower decoding rate. The combination of values indicates the diversity transmission method, that is, the data block is decoded with the instruction information with a higher decoding rate, and the combination of the RV value and the MCS index value in the instruction information with a lower decoding rate indicates the diversity transmission method.

The network device in the embodiment of the present application may be a device for communicating with a terminal device, and the network device may be a Global System for Mobile (GSM) system or a Code Division Multiple Access (CDMA) system. The base station (Base Transceiver Station, BTS) can also be a base station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) system, or an evolutionary base station (Evolutional base station in an LTE system). (NodeB, eNB, or eNodeB), or a wireless controller in a Cloud Radio Access Network (CRAN) scenario, or the network device may be a relay station, access point, or transmission and reception point , TRP), in-vehicle equipment, wearable equipment, and network equipment in the future 5G network or network equipment in the future evolved PLMN network, etc. For the convenience of description, the TRP is used as an example for illustration, but this embodiment of the present application does not Limitation.

The communication system in FIG. 1 may include at least one terminal device (for example, terminal device 10, terminal device 20, terminal device 30, terminal device 40, terminal device 50, and terminal device 60) and a network device 70. The network device 70 is used to provide communication services for the terminal device and access the core network. The terminal device can access the network by searching for synchronization signals, broadcast signals, and the like sent by the network device 70 to perform communication with the network. The terminal device 10, the terminal device 20, the terminal device 30, the terminal device 40, and the terminal device 60 in FIG. 1 can perform uplink / downlink transmission directly with the network device 70. In addition, the terminal device 40, the terminal device 50, and the terminal device 60 can also be regarded as a communication system, and the terminal device 60 can send scheduling information to the terminal device 40 and the terminal device 60.

It should be noted that the network device in the embodiment of the present application is described by using TRP as an example, but the present application is not limited thereto.

FIG. 2 is a schematic diagram of a multipoint cooperative communication system. As shown in FIG. 2, the multipoint cooperative communication system includes terminal equipment, TRP-A, and TRP-B. End devices are on the edge of TRP-A and / or TRP-B coverage. To enhance the reliability of data transmission, TRP-A and TRP-B use diversity transmission to send data to terminal equipment, that is, TRP-A and TRP-B send the same data to terminal equipment (for example, data 1).

Among them, the RV version used by TRP-A to send data to the terminal device is different from the RV version used by TRP-B to send data to the terminal device, or the scrambling method used by TRP-A to send data to the terminal device and TRP-B to the terminal device The data is transmitted using different scrambling methods.

It should be understood that the embodiments of the present application may be applied to a scenario including multiple TRPs, which is not limited in this application.

Multiple TRPs use a diversity scheme to send data to the terminal device. However, the terminal device cannot know the data transmission method used for the received data, that is, the terminal device cannot know the relationship between data from different TRPs, and it is still aimed at receiving data. The data of each TRP is parsed separately and fed back separately. For example, the data from two TRPs are parsed and failed to be parsed, and the terminal device feeds the parsed results to different TRPs separately, that is, the feedback results are given to the two TRPs. All the base stations have failed to parse. In fact, if the data from the two TRPs can be parsed to obtain a successful parsed result, the feedback result will degrade the system performance.

FIG. 3 is a schematic flowchart of a signal processing method according to an embodiment of the present application.

301. A network device sends a data block to a terminal device.

Specifically, at least two network devices may cooperatively send data blocks to the terminal device, that is, the at least two network devices diversityly send data blocks to the terminal device. Accordingly, the terminal device may receive the data blocks sent by the at least two network devices, where the data blocks sent by the at least two network devices include the same data.

302. The network device sends diversity instruction information to the terminal device, where the diversity instruction information is used to indicate that a data block sent to the terminal device is sent in diversity with the at least two network devices. The data block includes the same data as a data block sent by another network device among the at least two network devices.

Correspondingly, the terminal device receives diversity indication information sent by the network device and used to instruct the at least two data blocks received by the terminal device to be diversity-transmitted by the at least two network devices. Wherein, the at least two data blocks include the same data.

It should be noted that the sequence of steps 301 and 302 is not limited in the embodiment of the present application.

Specifically, the two network devices send data in diversity. The two network devices use the same or different physical layer processing methods to send the same data to the terminal device. The following embodiments may be represented by a “diversity transmission method”. In the following embodiments, the data processed by the physical layer is represented as a data block, and the data block includes data and an indication field indicating a physical layer processing mode. The data in the data blocks sent by diversity in the embodiments of the present application are the same, but the physical layer processing methods may be the same or different. Physical layer processing methods include scrambling, code modulation, and RV version.

Optionally, before sending the diversity instruction information, the network device may determine the diversity instruction information, that is, determine with which other network devices the network device sends data blocks in a diversity manner.

Optionally, the diversity indication information may be carried in a newly added field of the original signaling, that is, the network device notifies the terminal device that at least two data blocks received by the explicit indication are sent by at least two network devices in diversity. . For example, a bit is added, and a value of the bit is used to indicate that at least two data blocks received by the terminal device are transmitted by diversity of at least two network devices.

Specifically, the network device and the terminal device may agree in advance that the newly added field is used to carry diversity indication information, and the newly added field may directly indicate the diversity transmission mode, or may indirectly indicate the diversity transmission mode.

For example, the value of the bit indicates the diversity transmission mode directly. The terminal device does not need to consider the value of this field. For example, this field is a bit, that is, whether the bit is set to "1" or "0", the terminal device can determine that at least two data blocks received are at least Divided by two network devices. Or, when the terminal device and the network device agree in advance that the value of the newly added field is "1", the at least two data blocks received by the terminal device are instructed to be sent in diversity by at least two network devices. Or, when the terminal device and the network device agree in advance that the value of the newly added field is "0", the at least two data blocks received by the terminal device are instructed to be sent in diversity by at least two network devices.

As another example, an identifier is indicated by a bit value, and the identifier may indicate a data transmission mode. Different identifiers can indicate different data transmission methods. In the embodiment of the present application, an identifier indicating a diversity transmission mode may be carried on a newly added field.

Optionally, the diversity indication information may be carried in radio resource control (RRC) signaling, media access control element (MAC-CE) signaling, or downlink control information (Downlink control control information). (DCI) signaling adds a new field, which can improve the flexibility of network device indication.

It should be noted that the terminal device receiving the signaling carrying the diversity instruction information sent by one TRP or receiving the signaling carrying the diversity instruction information sent by multiple TRPs can know that the terminal device is scheduled by multiple TRP diversity.

Optionally, the diversity indication information may also be notified to the terminal device in an implicit indication manner. That is, the diversity indication information is carried in a reserved field of known signaling, or the original function of the field is released to indicate the diversity transmission mode.

Optionally, the diversity indication information is a first modulation and coding strategy (MCS) index value and a new data indication (NDI) value of the first data block.

Specifically, the diversity indication information may be a combination of a first MCS index value and an NDI value of a certain data block (for example, the first data block) of the at least two data blocks. That is, the combination of the respective values of the first MCS index value and the NDI value indicates that the received data block is transmitted in diversity.

Among them, in the traditional scheme, the MCS index value can be used to determine the modulation order, code rate, and spectral efficiency of the corresponding data block. As shown in Table 1, the MCS index value ranges from 0 to 31. The NDI is used to indicate whether the data block is initial transmission data or retransmission data, so that the terminal device subsequently performs processing corresponding to the initial transmission, or performs processing corresponding to the retransmission. In the case where the NDI indicates that the first data block is the first transmission data, the MCS index is generally 0-28; when the NDI indicates that the first data block is the retransmission data, the MCS index can take a value of 0-31. When the MCS index is When taking 29, 30, and 31, since the transmission block size (Transport Block Size, TBS) is known when the data is retransmitted, the coding rate can be calculated according to the modulation method.

In the embodiment of the present application, the first MCS index value and the NDI value are used to indicate that the data block received by the terminal device is sent in diversity. For example, in the embodiment of the present application, the original function of releasing a certain MCS index value and NDI value is released. To indicate the data diversity transmission method.

Optionally, the network device may preset a value of a certain MCS index value and a value of a certain NDI value, so that the terminal device obtains the received data block according to the MCS index value and the NDI value, and adopts diversity transmission for the network device. Way to send. Or the network equipment and the terminal equipment have predetermined a predetermined set of MCS index values and certain NDI values, so that the network equipment can flexibly select the MCS index value and the NDI value, and the terminal equipment determines the MCS When the index value and the NDI value are one of a predetermined set, it is learned that the received data block is sent by the network device in a diversity transmission mode.

Optionally, in the embodiment of the present application, the MCS index value may take any one of 29, 30, and 31, and the NDI value is 0 or 1, indicating that the received data block is transmitted in diversity.

Specifically, the terminal device may also determine whether the received data block is transmitted in diversity according to the MCS index value and whether the NDI is turned over. Among them, whether NDI is flipped can be understood as whether the current NDI value has changed from the previous NDI value, for example, from 0 to 1, or from 1 to 0. That is to say, in the case of the traditional scheme, when the NDI rollover indicates the initial transmission, the MCS index value is usually 0-28. This embodiment of the present application is used in a scenario where the traditional scheme is not used, that is, the NDI indicates the initial transmission. Any one of the values 31 and 31 implicitly indicates the diversity transmission mode, thereby saving signaling overhead. MCS can be fixed to one of 29, 30, and 31 in the protocol, or TRP can dynamically select from three values according to its own requirements.

In addition, the terminal device and the network device can set the MCS index value and the NDI value in advance. For example, the MCS index value is preset to any one of 0, 29, 30, and 31, and the NDI value is 0; or the MCS index value is preset to any of 0, 29, 30, and 31, and the NDI The value is 1.

For example, the MCS index value is 29 and the NDI is 0.

The MCS index value is 29, and the NDI is 1.

The MCS index is 29, and the NDI is from 0 to 1.

MCS index value is 29, NDI is from 1 to 0;

The MCS index is 30 and the NDI is 0.

The MCS index is 30 and the NDI is 1.

The MCS index value is 30, and the NDI is from 0 to 1.

The MCS index value is 30, and the NDI is from 1 to 0;

The MCS index is 31 and the NDI is 0.

The MCS index is 31 and the NDI is 1.

The MCS index value is 31, and the NDI is from 0 to 1.

The MCS index is 31 and the NDI is from 1 to 0.

MCS index value is 29, 30 or 31, NDI is 0;

The MCS index value is 29, 30, or 31, and the NDI is 1.

The MCS index value is 29, 30, or 31, and the NDI is from 0 to 1.

The MCS index value is 29, 30, or 31, and the NDI is from 1 to 0.

Optionally, the diversity indication information may also be a combination of a first MCS index value and a first RV value. In the embodiment of the present application, a data diversity transmission mode is indicated by releasing a function of an original MCS index value and an RV value.

Optionally, the first MCS index value may be a value that is not frequently used in the traditional scheme, for example, 0, 1, and 2. The first RV value is 1 or 2.

Optionally, the value of the first MCS index value and the first RV value may be a translation that satisfies the decoding of the first data block according to a combination of parameters corresponding to the first RV value and the first MCS index value. The bit rate is less than or equal to a preset decoding rate, and parameters corresponding to the first MCS index value include a modulation order and a bit rate.

Specifically, in the embodiment of the present application, in a case where multiple TRPs use diversity to send data blocks to terminal devices, the terminal device and the network device may agree to be configured by the network device as much as possible to analyze the corresponding data block with a lower decoding rate. A combination of the RV value and the MCS index value in the indication information. Specifically, a combination of an RV value and an MCS index value that decodes the corresponding data block according to a combination of parameters corresponding to the RV value and the MCS index value to indicate a data diversity is used to indicate data diversity. transfer method.

Optionally, multiple TRPs can be compared in advance, and the combination of the parameter corresponding to the RV value and the MCS index value to decode the corresponding data block has a lower RV value and MCS index value for indicating data diversity transmission the way.

Optionally, the first MCS index value may also be that in a scenario where the RV value is 1 or 2, the corresponding transmission code rate is greater than or equal to a preset transmission code rate.

Specifically, in a low density parity check code (LDPC) encoding scenario, when the RV value is 0 or 3, the decoding accuracy rate of the data block is relatively high. When the RV value is 1 or 2, and the code rate corresponding to the MCS value is greater than or equal to the preset transmission code rate, the accuracy of decoding the data block is low.

Optionally, the preset transmission code rate is 0.35.

Specifically, when the RV is 1 or 2, when the first MCS index value is a value corresponding to a transmission code rate greater than or equal to 0.35, the data decoding usually fails. As shown in Table 1, when the MCS index value is 27, the corresponding code rate is 910/1024 = 0.89. This embodiment of the present application uses a corresponding MCS index value greater than or equal to 0.35 and an implicit mode with an RV value of 1 or 2 to collectively indicate the data diversity transmission mode, thereby saving signaling overhead. For example, the agreement stipulates that RV is 1 and MCS is 27 as a recessive indication. The embodiment of the present application does not limit the specific value.

The terminal device can analyze the received data block when it learns the transmission mode of the received data block. At least one data block of the at least two data blocks obtains a parsing result, and sends the same feedback information to all network devices in the at least two network devices, or sends the same feedback information to one of the at least two network devices. Feedback information, so that the terminal device sends the same feedback information to each of the at least two network devices, which prevents network devices that send data blocks in a diversity transmission mode from receiving different feedback information, thereby improving feedback Accuracy. Or the terminal device sends feedback information to any one of the at least one network device, thereby saving feedback overhead. Or the terminal device sends feedback information to some network devices in the at least one network device.

It should be noted that the feedback information sent by the terminal device may be feedback for a transport block (TB) or feedback for a code block group (CBG), which is not limited in this application.

It should be understood that when the terminal device sends feedback information to any one of the at least one network device, the terminal device can flexibly decide which network device to send the feedback information to, or which network the network device and the terminal device pre-orient to which network The device sends feedback information, which is not limited in this application.

It should also be understood that the first parsing result may be a parsing success or a parsing failure. When the feedback information indicates that the analysis is successful, it may be indicated by an acknowledgement (Acknowledgement, ACK); when the feedback information indicates that the analysis is failed, it may be indicated by a negative answer (Negative Acknowledgement, NACK).

Optionally, after receiving the feedback information, the network device determines whether to resend the data block according to the feedback information. If the feedback information is that the parsing is successful, the data block does not need to be retransmitted; if the feedback information is that the parsing has failed, the network device can retransmit the data block.

Optionally, before sending the feedback information, the terminal device may obtain instruction information for parsing the first data block, and parse the first data block according to the instruction information for parsing the first data block.

Optionally, the indication information for parsing the first data block may further include a subcarrier interval and a cyclic prefix. , Symbol length, slot length, etc.

For example, the terminal device may analyze the first data block according to the MCS modulation order corresponding to the MCS index value, the transmission code rate, the spectral efficiency, and the RV version corresponding to the RV value, and whether the data block indicated by the NDI is an initial transmission or a retransmission. .

It should be noted that the instruction information for parsing the first data block may be pre-configured, or it may be an appointment, or may be currently configured by the network device.

Optionally, before sending the feedback information, the terminal device may further obtain instruction information for parsing the second data block, and the obtained instruction information for parsing the second data block may be similar to the first instruction information, and accordingly , The terminal device may parse the second data block according to the acquired instruction information for parsing the second data block.

Optionally, in the process of parsing the at least two data blocks by the terminal device, when only one data block is successfully parsed, the parsing result may be that the parsing is successful. In other words, if the terminal device parses one data block successfully, the terminal device may not parse other data blocks, thereby saving power consumption of the terminal device.

For example, during the parsing process, when the first data block is successfully parsed, the parsing result is that the parsing is successful, and other data blocks may not be parsed; if the first data block fails to parse, continue to parse the second data block. If the two data blocks are parsed successfully, the parsing result is parsed successfully.

Optionally, in the parsing process, after parsing all data blocks, if at least one parsing succeeds, the parsing result is parsing success.

Optionally, when parsing multiple data blocks is unsuccessful, the terminal devices may perform joint parsing, and the parsing result is a parsing result after joint parsing.

Specifically, the terminal device analyzes the first data block and the second data block jointly to obtain an analysis result according to the instruction information for analyzing the first data and the instruction information for analyzing the second data. If the joint parsing is successful, the parsing result is parsing success; if the joint parsing fails, the parsing result is parsing failure.

It should be noted that during the joint analysis process, the terminal device may place the data blocks sent by the cooperative network device in the same cache location for decoding.

Optionally, in a case where the diversity transmission mode is implicitly indicated by a parameter in the indication information (for example, the indication information used to parse the first data block), the terminal device may use other indication information (for example, the second data is used to parse the second data). Block instruction information), to determine specific parameter values in the instruction information used to parse the first data block.

It should be noted that the instruction information for parsing the first data block may be sent by a network device that sends the first data block, or may be sent by a network device that sends other data blocks. That is, the network device that sends the data block and the network device that sends the parsing information that parses the data block may be the same or different.

Optionally, the network devices may negotiate to send instruction information used by one network device to parse multiple data blocks.

Optionally, in a case where the diversity transmission mode is implicitly indicated by a parameter in the indication information (for example, the indication information used to parse the first data block), other parameters of the indication information used to parse the first data block are also It may be determined by corresponding parameters in other indication information (for example, indication information used to parse the second data block).

For example, when the diversity transmission method is indicated by a combination of the first MCS index value and the NDI value, the RV value used to parse the first data block may be the RV indication information of the first data block, or may be used by The RV value of the second data block is determined.

Optionally, when the diversity transmission mode is indicated by a combination of the first MCS index value and the NDI value, the MCS index value and the NDI value in the indication information for parsing the first data block may be fixed in advance value.

Optionally, when the diversity transmission mode is indicated by a combination of the first MCS index value and the NDI value, the MCS index value and the NDI value in the indication information used to parse the first data block may be based on other indication information. The MCS index value and NDI value are determined.

Specifically, for example, the indication information for parsing the first data block includes a second MCS index value, and the terminal device may determine the MCS index value for parsing the first data block according to the second MCS index value.

Optionally, in a case where the diversity indication information is indicated by a combination of the MCS index value and the NDI value, and the combination of the MCS index value and the NDI is carried in the indication information configured to instruct the parsing of the first data block by the network device, then The MCS can also be used to parse the first data block. In other words, the MCS in the instruction information for instructing to parse the first data block can either maintain the original function or combine it with the NDI to have a new function.

It should be noted that, in this scenario, the NDI used to parse the first data block may be determined by the NDI used to parse the second data block.

Optionally, when the diversity transmission mode is indicated by a combination of the first MCS index value and the NDI value, one of the MCS index value and the NDI value in the indication information for parsing the first data block may be It is a predetermined fixed value, and the other is determined according to corresponding parameters in other instructions.

For example, the MCS index value in the instruction information for parsing the first data block is a predetermined fixed value, and the NDI value is determined according to the NDI in the instruction information for parsing the second data block.

Optionally, in a case where the diversity transmission mode is indicated by a combination of the first MCS index value and the first RV value, the MCS index value and the RV value in the indication information for parsing the first data block may be predetermined Fixed value.

For example, the RV value is 0, 1, or 2, and the MCS index value is any of 0-31.

Optionally, when the diversity transmission mode is indicated by a combination of the first MCS index value and the first RV value, the MCS index value and the RV value in the indication information used to parse the first data block may be based on other indication information The MCS index value and RV value are determined.

Optionally, when the diversity transmission mode is indicated by a combination of the first MCS index value and the first RV value, one of the MCS index value and the RV value in the indication information for parsing the first data block may be It is a predetermined fixed value, and the other is determined according to corresponding parameters in other instructions.

For example, the MCS index value in the instruction information for parsing the first data block is a predetermined fixed value, and the RV value is determined according to the RV in the instruction information for parsing the second data block. Alternatively, the RV value in the instruction information for parsing the first data block is a predetermined fixed value, and the MCS index value is determined according to the MCS index value in the instruction information for parsing the second data block.

Optionally, it is described that the indication information used to parse the second data block includes the second RV value, and the terminal device may use the second RV value as the first RV value to parse the first data block.

Optionally, description is made by taking the indication information for parsing the second data block including the second RV value as an example, and the terminal device may determine the first RV value according to a functional relationship that the first RV value and the second RV value satisfy.

Specifically, if the second RV is represented by RV2 and the first RV is represented by RV1, RV1 and RV2 can satisfy RV1 = mod ((RV2 + N), M), where M and N are preset positive integers, and RV2 is described as The second RV value, RV1 is the RV value in the indication information used to parse the first data block. For example, if M = 4, N = 1, and RV2 = 1, then RV1 = 2.

Optionally, in a case where the diversity indication information uses some parameters in the indication information for parsing the first data block, the diversity indication information may be the same as the indication information configured by the network device for parsing the first data block. It can be carried in the same DCI or in different DCIs.

Specifically, taking two TRPs as an example, the TRP negotiates through a DCI (for example, the first DCI) to carry diversity instruction information, instruction information for parsing a first data block, and instruction information for parsing a second data block. The diversity indication information and the indication information for parsing the first data block may also be carried through the first DCI, and the indication information for parsing the second data block may be carried through the second DCI.

It should be noted that after the parameters included in the indication information configured by the network device for parsing the data block are used to indicate the diversity transmission mode, the terminal device needs to obtain the parameters of the parsing data block in other ways to parse the data block.

Optionally, whether the diversity instruction information uses the content in the instruction information configured to parse the first data block configured by the network device or the content in the instruction information used to parse the second data block may be fixed by the protocol or may be It is determined by the network equipment, which is not limited in this application.

Optionally, in a case where the diversity transmission mode is indicated by the first MCS index value and the first RV value, the network device may select the MCS index value with the lower decoding rate included in the two indication information in combination with the RV as 1 or 2 to indicate the diversity transmission method, thereby improving the decoding rate of the data block.

Specifically, when the RV is 1 or 2, the larger the transmission code rate corresponding to the MCS index value is, the higher the error rate is. Therefore, the network device can flexibly select the instruction information for parsing the first data block and The larger MCS index value in the instruction for parsing the second data block and the RV value corresponding to the larger MCS index value indicate the diversity transmission mode, and the other instruction information is used for parsing the data block. For example, the instruction information used to parse the first data block includes RV1 = 2 and the MCS index value m, the instruction information used to parse the second data block includes RV2 = 2 and the MCS index value n, and the MCS index value m corresponds to 3. The transmission code rate is 251/1024, and the MCS index value n is 13. The corresponding transmission code rate is 490/1024. Then the network device can select the MCS index value of 13 and use RV2 to indicate the diversity transmission mode.

Optionally, the diversity indication information may also implicitly indicate other performance, so that the diversity indication information can be fully utilized, and system performance is further improved.

Optionally, the diversity indication information may also indicate that the corresponding data is invalid, which prevents the terminal device from parsing the invalid data block, thereby reducing the power consumption of the terminal device.

Specifically, if the DCI carries indication information indicating two data blocks, each indication information may include a codeword, or only one indication information includes a codeword, and the diversity indication information may indicate that a certain data block is invalid, that is, the current There is only one codeword transmitted.

Therefore, in the signal processing method in the embodiment of the present application, the terminal device receives diversity indication information, and the diversity indication information indicates that the received at least two data blocks are at least two data blocks including the same data. The terminal device is informed that the received Data block transmission method, at least one data block of the at least two data blocks may be parsed to obtain a parsing result, and the same feedback information may be sent to all network devices of the at least two network devices, or to the at least two A network device in the network device sends the feedback information, so that the terminal device sends the same feedback information to each of the at least two network devices, which avoids that the network device that sends the data block in the manner of diversity transmission receives Different feedback information, which improves the accuracy of feedback.
