Description
Technical Field
The embodiment of the invention relates to the technical field of wireless, in particular to a control information transmission method, a control information transmission device, control information transmission equipment and a storage medium.
Background
In Long Term Evolution (LTE) and all interconnect V2X (V2X), a physical channel in a direct Link (Side-Link) generally transmits in a broadcast transmission manner. The time-frequency domain resource of the Physical Channel of the Physical direct Link Control Channel (PSCCH) carrying the Scheduling information (Scheduling Assignment) and the Physical Channel of the Physical direct Link shared Channel (PSCCH) carrying the data adopts the configuration mode of the resource pool, and the resource pool is configured by the high-level signaling or the pre-configuration mode. The PSCCH resource pool and the PSCCH resource pool are Frequency Division Multiplexing (FDM), and the terminal in Mode 3(Mode 3) receives the PDCCH sent by the base station and instructs the terminal to send scheduling information of PSCCH on the direct link. And the terminal in the Mode 4(Mode 4) randomly selects resources in the resource pool to transmit the PSCCH and the PSSCH in a sensing Mode. Meanwhile, since the LTE V2X physical channel adopts a broadcast transmission mode, all terminals can decode the physical channels transmitted by other terminals.
In vehicles of New Radio (NR) technology and all interconnect V2X, the requirements for throughput, reliability and latency are greatly improved compared to LTE V2X. In the conventional LTE V2X, a physical channel is sent in a broadcast manner, and since there is no Hybrid Automatic Repeat Request (HARQ) feedback for data, a terminal cannot determine whether other terminals correctly receive the data, so that the reliability of the data is reduced. Meanwhile, since there is no reporting process for channel quality information, the Modulation and Coding Scheme (MCS) selection of the transmitting terminal is inaccurate when transmitting data, which may result in a decrease in spectrum utilization efficiency or an increase in packet loss rate of the receiving terminal. Therefore, mechanisms such as HARQ feedback and Channel State Information (CSI) measurement reporting need to be introduced into NR V2X, so that the spectrum utilization rate can be effectively improved, the packet loss rate can be reduced, and the throughput and reliability requirements of NR V2X can be improved.
However, if a receiving end terminal device (UE) needs to perform HARQ feedback or CSI reporting on data, a transmission method of control information fed back by the receiving end terminal device needs to be defined.

Fig. 1 is a schematic diagram of an implementation flow of a control information transmission method according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step S101, determining a first direct link control information format or a second direct link control information format.
Step S102, the terminal transmits a physical straight-through link control channel PSCCH carrying a first straight-through link control information format or a second straight-through link control information format.
Here, the first direct link control information format is used to carry hybrid automatic repeat request acknowledgement HARQ-ACK information and/or channel state information, and the second direct link control information format is used to carry scheduling information of a direct link.
The control information format of the first direct link control information format and/or the second direct link control information format may be an NR sidelink control information format, and the HARQ and/or the CSI is carried on the configured NR sidelink control information format.
In an embodiment of the present invention, the first direct link control information format and the second direct link control information format are carried on the same physical channel. The physical channel may be a physical through link shared channel PSCCH and/or a physical through link control channel PSCCH.
In this embodiment, the terminal may obtain the configuration of the NR sidelink control information format through the following four ways:

Here, the payload size of the first and second through link control information formats is a length of a bit of the first and second through link control information formats. In this embodiment, the first direct link control information format and the second direct link control information format have different loads.
For the scheme of predefining the load sizes of the first direct link control information format and the second direct link control information format through a protocol in this embodiment, the load sizes of the first direct link control information format and the second direct link control information format may be predefined for a terminal through a preset protocol. The preset protocol may be any protocol as long as the preset protocol can satisfy that the defined loads of the first direct link control information format and the second direct link control information format are different in size.

The high-level signaling may be a Radio Resource Control (RRC) protocol or a Media Access Control (MAC) protocol.
For the scheme of pre-configuring the load sizes of the first direct link control information format and the second direct link control information format in this embodiment, the load sizes of the first direct link control information format and the second direct link control information format pre-configured by the terminal factory or the terminal by the user may be received for the terminal. The present embodiment does not limit the type of the preconfiguration and the method of the preconfiguration.

Here, the value of the RNTI is a CRC check code for scrambling the first and second through link control information formats. By scrambling the CRC check codes of the first and second through link control information formats, the CRC check codes of the first and second through link control information formats may be made different. In this embodiment, different RNTIs are used to scramble CRC check codes of the first and second direct link control information formats, so that it can be ensured that the scrambled CRC check codes are different.
For the scheme of predefining the values of the radio network temporary identifiers RNTI used for scrambling the cyclic redundancy check CRC check codes of the first through link control information format and the second through link control information format through a protocol in this embodiment, the values of the radio network temporary identifiers RNTI used for scrambling the cyclic redundancy check CRC check codes of the first through link control information format and the second through link control information format may be predefined for the terminal through a preset protocol.

For the scheme of receiving the values of the radio network temporary identifiers RNTI configured by the high-level signaling and used for scrambling the cyclic redundancy check CRC check codes of the first through link control information format and the second through link control information format in this embodiment, the values of the radio network temporary identifiers RNTI configured by the base station through the high-level signaling and used for scrambling the cyclic redundancy check CRC check codes of the first through link control information format and the second through link control information format may be received for the terminal. The higher layer signaling may be an RRC protocol or an MAC protocol.
For the scheme of pre-configuring the values of the radio network temporary identifiers RNTI used for scrambling the cyclic redundancy check CRC check codes of the first direct link control information format and the second direct link control information format in this embodiment, the values of the radio network temporary identifiers RNTI used for scrambling the cyclic redundancy check CRC check codes of the first direct link control information format and the second direct link control information format, which are pre-configured by the terminal from the factory or by the user for the terminal, may be received for the terminal. The present embodiment does not limit the type of the preconfiguration and the method of the preconfiguration.
The third method comprises the following steps: predefining initialization values of scrambling sequences of the first and second direct link control information formats through a protocol, or receiving initialization values of scrambling sequences of the first and second direct link control information formats configured by a high-level signaling, or preconfiguring initialization values of scrambling sequences of the first and second direct link control information formats, where the first and second direct link control information formats employ different scrambling sequences.
Here, the scrambling sequence is used to scramble the first and second through link control information formats. The first and second direct link control information formats may be made different by scrambling the first and second direct link control information formats.
For the scheme of predefining initialization values of scrambling sequences of the first and second direct link control information formats by a protocol in this embodiment, initialization values of scrambling sequences of the first and second direct link control information formats may be predefined by a preset protocol for a terminal. The preset protocol may be any protocol as long as the preset protocol can satisfy that the scrambling sequences defined for scrambling the first and second direct link control information formats are different.

The present embodiment does not limit the type of the preconfiguration and the method of the preconfiguration.
The method is as follows: the first and second through-link control information formats are distinguished by protocol pre-defining different bits (bits).
For example, the indication bit may be 0 in the first direct link control information format and the indication bit may be 1 in the second direct link control information format, or the indication bit may be 1 in the first direct link control information format and the indication bit may be 0 in the second direct link control information format, so as to distinguish the at least two direct link control information formats.
Fig. 2 is a schematic view of an application scenario of a control information transmission method according to an embodiment of the present invention, as shown in fig. 2, N vehicles with NR V2X and/or LTE V2X are located in the same network 21, where the N vehicles are a vehicle 11, a vehicle 12, a vehicle 13 … …, and a vehicle 1N, and all of the N vehicles may perform signaling interaction with the network 21, and the network 21 may perform signaling interaction with the base station 31. When any one of the N vehicles (for example, the vehicle 11) performs data transmission with another vehicle (for example, the vehicle 12) in the network 31, when the vehicle 11 receives a data packet sent by the vehicle 12, in order to enable the vehicle 12 to determine that the vehicle 11 has correctly received the data packet and ensure reliability of the data transmission, HARQ feedback and CSI measurement report may be performed so that the vehicle 12 determines that the vehicle 11 has correctly received the data packet. Then, the control information transmission method provided by this embodiment may be adopted, and the terminal transmits a physical direct link control channel PSCCH carrying a first direct link control information format or a second direct link control information format; the first direct link control information format is used for carrying hybrid automatic repeat request acknowledgement (HARQ-ACK) information and/or channel state information, and the second direct link control information format is used for carrying scheduling information of a direct link.
In the control information transmission method provided by the embodiment of the invention, a terminal transmits a physical direct link control channel PSCCH carrying a first direct link control information format or a second direct link control information format; the first direct link control information format is used for carrying hybrid automatic repeat request acknowledgement (HARQ-ACK) information and/or channel state information, and the second direct link control information format is used for carrying scheduling information of a direct link. Therefore, the feedback information of the receiving terminal can be conveniently detected by the sending terminal, and the detection overhead of the sending terminal is reduced as much as possible; and can adapt to different control information load sizes, and simplify signaling overhead.
Example two
The embodiment of the invention provides a control information transmission method, which is applied to a data receiving terminal, and then an opposite terminal corresponding to the data receiving terminal can be a data sending terminal. The functions implemented by the control information format configuration method of this embodiment may be implemented by a processor in the terminal calling a program code, and of course, the program code may be stored in a computer storage medium, and as seen, the terminal at least includes a processor and a storage medium.
Fig. 3 is a schematic diagram of an implementation flow of a second control information transmission method according to an embodiment of the present invention, and as shown in fig. 3, the method includes the following steps:
step S301, the terminal transmits a physical direct link control channel PSCCH carrying a first direct link control information format or a second direct link control information format.
Here, the first direct link control information format is used to carry hybrid automatic repeat request acknowledgement HARQ-ACK information and/or channel state information, and the second direct link control information format is used to carry scheduling information of a direct link.
The control information format of the first direct link control information format and/or the second direct link control information format may be an NR sidelink control information format, and the HARQ and/or the CSI is carried on the configured NR sidelink control information format.
In this embodiment, the terminal may acquire the configuration of the NR sidelink control information format through four ways, which are the same as the four ways in step S101 in the first embodiment.
Step S302, the type of the physical channel carried by the HARQ-ACK information and/or the channel state information is indicated through the first direct link control information format.
In an embodiment of the present invention, the first direct link control information format includes a resource allocation information field of a physical direct link shared channel PSSCH, then step S302 indicates, through the first direct link control information format, a type of a physical channel carried by HARQ-ACK information and/or channel state information, where the method may further include:
step S3021, indicating the type of the physical channel carried by the control information through the resource allocation information field.
Here, the types of the physical channels include the PSCCH and the PSCCH.
For example, if bits of the resource allocation information field are all 0, the HARQ-ACK information and/or the channel state information may be carried only on the PSSCH; if the bits of the resource allocation information field are not all 0, the HARQ-ACK information and/or the channel state information can be carried on the PSCCH
In another embodiment of the present invention, the first direct link control information format includes at least one bit information bit and a resource allocation information field of the psch; then, the step S302 of indicating the type of the physical channel carried by the HARQ-ACK information and/or the channel state information through the first direct link control information format may be implemented by:
step S3022, the type of the physical channel carried by the HARQ-ACK information and/or the channel state information is indicated by the bit information bits.
Here, the types of the physical channels include the PSCCH and the PSCCH.
In step S3022, the bit information bits indicate the type of the physical channel carried by the HARQ-ACK information and/or the channel state information, and may indicate the type of the physical channel carried by the HARQ-ACK information and/or the channel state information according to the bit information bits in a manner predefined by a protocol.
For example, how the bit information bits indicate the type of physical channel carried by the HARQ-ACK information and/or channel state information may be predefined by a protocol. Of course, the bit information bits may be configured by receiving higher layer signaling to indicate the type of the physical channel carried by the HARQ-ACK information and/or the channel state information, or the bit information bits may be preconfigured by receiving to indicate the type of the physical channel carried by the HARQ-ACK information and/or the channel state information.
In this embodiment, the first direct link control information format includes at least one bit information bit, and then, when how the bit information bit indicates the type of the physical channel carried by the HARQ-ACK information and/or the channel state information is predefined by a protocol, how one bit information bit indicates the type of the physical channel carried by the HARQ-ACK information and/or the channel state information may be predefined by the protocol, and how a plurality of bit information bits indicate the type of the physical channel carried by the HARQ-ACK information and/or the channel state information may also be predefined by the protocol.
For example, when it is predefined by the protocol how one bit information bit indicates the type of physical channel carried by the HARQ-ACK information and/or channel state information, e.g. if the bit information bit is 0, the HARQ-ACK information and/or channel state information is carried only on the PSCCH; if the bit information bit is 1, the HARQ-ACK information and/or the channel state information is carried on the PSSCH only. When how a plurality of bit information bits indicate the type of physical channel carried by the HARQ-ACK information and/or channel state information is predefined by a protocol, for example, if the bit information bits are 01, the HARQ-ACK information and/or the channel state information is carried on PSSCH only; if the bit information bit is 10, the HARQ-ACK information and/or the channel state information are only loaded on the PSCCH; and if the bit information bit is 11, the HARQ-ACK information and/or the channel state information are simultaneously carried on the PSCCH and the PSSCH.
Step S3023, indicating a location of the physical resource on the PSSCH by the resource allocation information field.
Here, the physical resource of the psch is indicated by a resource allocation information field in the first direct link control information format.
The control information transmission method provided by the embodiment of the invention predefines the type of the physical channel carried by the HARQ-ACK information and/or the channel state information through the resource allocation information field or the bit information bit indication by a protocol, thereby accurately indicating the type of the physical channel carried by the control information. In addition, through different control information format configuration schemes for bearing HARQ and/or CSI, the feedback information of the receiving terminal can be conveniently detected by the sending terminal, and the detection overhead of the sending terminal is reduced as much as possible.
EXAMPLE III
The embodiment of the invention provides a control information transmission method, which is applied to a data receiving terminal, and then an opposite terminal corresponding to the data receiving terminal can be a data sending terminal. The functions implemented by the control information format configuration method of this embodiment may be implemented by a processor in the terminal calling a program code, and of course, the program code may be stored in a computer storage medium, and as seen, the terminal at least includes a processor and a storage medium.
In the control information transmission method provided by the embodiment of the invention, a terminal sends a first direct link control information format, wherein the first direct link control information format is used for carrying HARQ-ACK bits and/or CSI bits; the first direct link control information format is carried on a physical direct link control channel.
The terminal sends a second straight-through link control information format which is used for scheduling a straight-through link shared channel; the second through link control information format is carried on a physical through link control channel.
In the embodiment of the present invention, the first direct link control information format and the second direct link control information format have the following configuration schemes:
the first method comprises the following steps: the first direct link control information format and the second direct link control information format have different loads. The load size of the first and/or second through-link control information format is configured or preconfigured by protocol pre-defined or higher layer signaling.
And the second method comprises the following steps: CRC check codes of the first direct link control information format and the second direct link control information format adopt different RNTIs for scrambling. Configuring or pre-configuring, by a protocol pre-defined or higher layer signaling, a value of an RNTI used to scramble CRC check codes of the first and second through link control information formats.
And the third is that: the first and second direct link control information formats employ different scrambling sequences. Configuring or pre-configuring initialization values of scrambling sequences of a first and a second through link control information formats through protocol pre-definition or higher layer signaling.
And fourthly: and distinguishing the first through link control information format and the second through link control information format by using different bits respectively. For example: the indication bit is 0 in the first direct link control information format, and the indication bit is 1 in the second direct link control information format.
In an embodiment of the present invention, the first direct link control information format may indicate a physical channel carried by HARQ-ACK information and/or channel state information, for example, the indication may be performed in the following three manners:
the first method comprises the following steps: the first direct link control information format comprises a resource allocation information field of a physical direct link shared channel. If the bits of the scheduling information field are all 0, the HARQ-ACK information and/or the channel state information are only carried on the physical through link control channel, and if the bits of the scheduling information field are not all 0, the HARQ-ACK information and/or the channel state information are carried on the physical through link shared channel. And, the physical resources of the physical through link shared channel are indicated by a resource allocation information field in the first through link control information format.
And the second method comprises the following steps: in the first through link control information format, 1bit information bit is used for indicating a physical through link channel carried by HARQ-ACK information and/or channel state information. And predefining a physical through link channel corresponding to the 1bit information bit through a protocol. For example, if the bit information bit is 0, the HARQ-ACK information and/or the channel state information is only carried on the physical through link control channel; if the bit information bit is 1, the HARQ-ACK information and/or the channel state information is only carried on the physical through link shared channel. And, the physical resources of the physical through link shared channel are indicated by a resource allocation information field in the first through link control information format.
And the third is that: in the first through link control information format, 2bit information bits are used for indicating a physical through link channel carried by HARQ-ACK information and/or channel state information. The protocol predefines the physical channel carried by the 2-bit information bit indicating HARQ-ACK information and/or channel state information. For example, when the bit information bit is 01, the HARQ-ACK information and/or the channel state information is only carried on a physical through link shared channel, and a physical resource of the physical through link shared channel is indicated by a resource allocation information field in the first through link control information format; when the bit information bit is 10, the HARQ-ACK information and/or the channel state information are only carried on a physical straight-through link control channel; when the bit information bit is 11, the HARQ-ACK information and/or the channel state information are simultaneously carried on a physical through link control channel and a physical through link shared channel. And, the physical resources of the physical through link shared channel are indicated by a resource allocation information field in the first through link control information format.
In the embodiment of the invention, the control information format for bearing the HARQ and/or the CSI and the control information format for scheduling the PSSCH are both borne on a direct link control channel. The configuration scheme of the control information format is as follows: the SCI load size of the scheduling PSSCH is different, or the CRC scrambling is carried out by using a different RNTI than the SCI of the PSSCH, or the type of the control information is indicated in the control information format. And, the control information may be carried on a physical through link control channel and/or a physical through link shared channel.

In the control information transmission method provided by the embodiment of the invention, the terminal sends one or more physical channels, and the physical channels carry control information, wherein the control information can be HARQ-ACK and/or CSI.
In the embodiment of the present invention, the control information format has the following schemes:
the first method comprises the following steps: the load size of the control information format is different from the load size of the SCI format of the scheduling PSSCH. The payload size of the control information format is configured or preconfigured by protocol pre-defined or higher layer signaling.
And the second method comprises the following steps: the load size of the control information format is the same as the load size of the SCI format of the scheduling PSSCH. And the CRC check codes of the control information format and the SCI format of the scheduling PSSCH adopt different RNTIs for scrambling. Configuring or pre-configuring a value of an RNTI of a CRC check code for scrambling the control information format and the SCI format of the scheduling PSSCH through protocol pre-definition or higher layer signaling.
And the third is that: the load size of the control information format is the same as the load size of the SCI format of the scheduling PSSCH. And distinguishing the two control information formats by using different bits in the control information format and the SCI format of the scheduling PSSCH respectively. For example: the indication bit is 0 in the control information format, and is 1 in the SCI format of the scheduling PSSCH.
In the embodiment of the present invention, the physical channel for carrying the control information has the following schemes:
the first method comprises the following steps: the control information is carried only on the physical control channel.

If the bits of the scheduling information field are all 0, the control information is only carried on the physical control channel, and if the bits of the scheduling information field are not all 0, the information is carried on the physical shared channel. The resource location of the physical shared channel is indicated by an information field in the control information format.
The second method comprises the following steps: and the control information format indicates a physical channel carried by the control information by using bit information bits. For example, the physical channel for indicating the control information bearer by the bit information bits may have the following two schemes:

For example, if the bit information bit is 0, the control information is only carried on the physical control channel; the bit information bit is 1, and the control information is only carried on the physical shared channel. The resource location of the physical shared channel is indicated by an information field in the control information format.
