However, LTE (Long Term Evolution) V2X communication can only support some basic security V2X applications.

[0138] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0139] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. The singular forms of "a", "said" and "the" used in this disclosure and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0140] It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0141] Figure 1 is a flow chart of a control information transmission method according to an exemplary embodiment. Figure 2 is an application scenario diagram of a control information transmission method according to an exemplary embodiment; the control information transmission method can be used for a control information sending end in direct communication, wherein the control information includes a first part of control information and a second part of control information; Figure 1 As shown, the control information transmission method may include the following steps 110-130:

[0142] In step 110, a first portion of control information is sent to a control information receiving end via a first physical layer channel occupying a first time-frequency resource.

[0143] In the disclosed embodiment, the size of the first part of the control information may be fixed, and the size of the second part of the control information may not be fixed; the first physical layer channel may be a PSCCH (Physical Sidelink Control Channel). That is, the control information transmitter may send the first part of the control information via the PSCCH; correspondingly, when the control information receiver receives the first part of the control information on the PSCCH, it needs to perform blind detection.

[0144] In the related technology, in order to support the use of physical layer HARQ (Hybrid automatic repeat request) feedback retransmission mechanism for unicast and multicast services of direct communication, additional HARQ related information needs to be included in the SCI (Sidelink Control Information) sent by the control information sender to the control information receiver. For example, HARQ process ID, physical layer source ID, NDI (New Data Indicator), Redundancy Version (RV), etc. For broadcast communication, since HARQ feedback is not supported, these control information are not required. Since the Internet of Vehicles service needs to support unicast, multicast and broadcast services at the same time, control information of inconsistent sizes will appear in the Internet of Vehicles communication. However, for control information of inconsistent sizes, if the same modulation and coding method is used for transmission, time-frequency resources of different sizes will be occupied, resulting in an increase in the complexity of blind detection.

[0145] Therefore, in the embodiment of the present disclosure, in order to avoid the occurrence of control information of inconsistent size, the control information transmitter can divide the control information into two parts for transmission, namely, the first part of the control information and the second part of the control information, the size of the first part of the control information is fixed, and the size of the second part of the control information is not fixed, so that the size of the first part of the control information is consistent regardless of unicast, multicast or broadcast, while the size of the second part of the control information is inconsistent (for example, there may be no second part of the information in broadcast). For the control information receiver, the reception of the first part of the control information needs to be blindly detected, while the reception of the second part of the control information may not be blindly detected, but is received according to the size of the second time-frequency resource occupied by the transmission of the second part of the control information indicated by the first indication information, which can reduce the blind detection complexity of the control information receiver.

[0146] The first part of the control information may include common information and information related to user perception, such as MCS (Modulation and Coding Scheme), frequency resources used for related PSSCH transmission (for example, starting PRB (Physical Resource Block) position, starting PRB size, etc.), PSSCH transmission time related information (may also be implicit or fixed, so no indication is required), blind retransmission related information, resource occupancy related information (such as indicating future resource occupancy), second part of the control information related indication information, etc. In addition, the target address may also be mentioned in the first part of the control information.

[0147] The second part of the control information may include additional control information. In one embodiment, in order to support HARQ retransmission, the second part of the control information may include HARQ related information, and the first part of the control information may not include HARQ related information, which ensures that HARQ retransmission can be supported and avoids the situation where the size of the first part of the control information is inconsistent.

[0148] In step 120, first indication information is sent to a control information receiving end, where the first indication information is used to indicate the size of a second time-frequency resource, where the second time-frequency resource is the time-frequency resource occupied by the transmission of the second part of the control information.

[0149] In the disclosed embodiment, the second part of the control information may be transmitted using a control channel, i.e., PSCCH, like the first part of the control information, or may be transmitted together with data using a data channel, i.e., PSSCH (Physical Sidelink Control Channel). Therefore, before sending the second part of the control information, the control information transmitter needs to notify the control information receiver of the size of the second time-frequency resources occupied by the transmission of the second part of the control information through the first indication information, so that the control information receiver can determine the size of the second time-frequency resources based on the first indication information and receive the second part of the control information on the second time-frequency resources.

[0150] There are many factors that affect the size of the second time-frequency resource. For example, when the second part of the control information and data are transmitted together using the data channel, i.e., PSSCH, the factors that affect the size of the second time-frequency resource may include but are not limited to at least one of the following: (1) the number of information bits of the second part of the control information; (2) the time-frequency resource size of the PSSCH; (3) the adjustment coding method when the data is transmitted using the PSSCH; (4) the number of bits when the data is transmitted using the PSSCH.

[0151] In one embodiment, before the above step 120, the following steps may also be included:

[0152] (1-1) Calculate the size of the second time-frequency resource according to the first parameter.

[0153] (1-2) Determine the first indication information according to the value of the first parameter.

[0154] In one embodiment, the size of the second time-frequency resource in the above (1-1) may be proportional to the value of the first parameter in the above (1-2).

[0155] In one embodiment, the first parameter in the above (1-1) may include the modulation coding efficiency of the second part of the control information.

[0156] In one embodiment, the second physical layer channel used to transmit the second part of the control information may be a physical layer channel used for data transmission, and the first parameter in the above (1-1) may include a parameter for adjusting the ratio of the coding efficiency of the second part of the control information and the data information.

[0157] For example: predefine or preconfigure the modulation and coding method of the second part of the control information, such as QPSK (Quadrature Phase Shift Keying) modulation, 1 / 3 code rate; then calculate the number of time and frequency units required under a given modulation and coding method (that is, the size of the second time and frequency resources) based on the number of information bits of the second part of the control information (after channel coding).

[0158] For another example: predefine the modulation mode of the second part of the control information, such as QPSK modulation; the coding efficiency of the second part of the control information is related to the number of information bits of the data to be transmitted in the PSSCH; assuming that the number of time-frequency units available for data or the second part of the control information in the PSSCH is K, the number of bits of the data before channel coding is M, and the number of bits of the second part of the control information is N, then the number of time-frequency units occupied by the second part of the control information (i.e., the size of the second time-frequency resource) is proportional to K, inversely proportional to M, and proportional to N. The specific implementation process is shown in formula (1).

[0159]

[0160] In the above formula (1), K is the number of time-frequency units in PSSCH that can be occupied by data or the second part of control information, N is the number of bits of the second part of control information, M is the number of bits of data before channel coding, and C is other parameters that may affect the number of time-frequency units occupied by the second part of control information.

[0161] Another example: define multiple possible modulation and coding modes of the second part of the control information, and indicate which modulation and coding mode to use through the information field in the first part of the control information. For example: the first part of the control information contains 2 bits of information, which can indicate 4 possible modulation and coding modes; or, through certain information fields in the first part of the control information, implicitly indicate which adjustment and coding mode to use, for example, when the MCS field indicates that the data modulation and coding mode is QPSK, the second part of the control information uses modulation and coding mode 1, and when the MCS field indicates that the data modulation and coding mode is 16QAM (Quadrature Amplitude Modulation, orthogonal amplitude modulation), the second part of the control information uses modulation and coding mode 2, and so on.

[0162] For another example: define a parameter alpha (i.e., the first parameter) for adjusting the ratio of the coding efficiency of the second part of the control information and the data information, and the value of the first parameter can be one of {1, 1.2, 1.4, ...}; then the number of time-frequency units occupied by the second part of the control information (i.e., the size of the second time-frequency resource) is proportional to the value of alpha, and its specific implementation process is shown in formula (2). The first indication information is 3-bit information, which can indicate 8 values ​​of the first parameter. Correspondingly, the control information receiving end can also use the same method to calculate the number of time-frequency units occupied by the second time-frequency resource (i.e., the size of the second time-frequency resource).

[0163]

[0164] In the above formula (2), K is the number of time frequency units in PSSCH that can be occupied by data or the second part of control information, N is the number of bits of the second part of control information, M is the number of bits of data before channel coding, and alpha is a parameter for adjusting the ratio of the coding efficiency of the second part of control information and data information.

[0165] In one embodiment, when executing the above (1-2), the value of the first parameter in the base station downlink signaling configuration or the value of the first parameter included in the pre-configuration may be used to implement it, and the implementation process may include:

[0166] (2-1) receiving a base station downlink signaling configuration, and determining the first indication information using a value of the first parameter indicated in the downlink signaling configuration; or

[0167] (2-2) Determine the first indication information using the value of the first parameter indicated in the preconfiguration.

[0168] In one embodiment, when executing the above (1-2), the first mapping relationship in the base station downlink signaling configuration or the second mapping relationship included in the pre-configuration may be used to implement it, and the implementation process may include:

[0169] (3-1 receiving a base station downlink signaling configuration, obtaining a first mapping relationship between a value of the first parameter and the first indication information, and determining the first indication information using the first mapping relationship; or

[0170] (3-2) Obtain a second mapping relationship between the value of the first parameter included in the preconfiguration and the first indication information, and use the second mapping relationship to determine the first indication information.

[0171] In step 130, the second part of control information is sent to the control information receiving end through the second physical layer channel occupying the second time-frequency resource.

[0172] In the disclosed embodiment, since the second part of the control information may be transmitted using the control channel, i.e., PSCCH, like the first part of the control information, or may be transmitted using the data channel, i.e., PSSCH (Physical Sidelink Shared Channel), the second physical layer channel used to transmit the second part of the control information may be PSCCH or PSSCH. That is, the first physical layer channel in the above step 110 and the second physical layer channel in the above step 130 may be the same or different.

[0173] In addition, for the control information sending end, the above steps 110, 120 and 130 may be in parallel relationship, without a strict temporal relationship. Therefore, the present disclosure does not limit the execution order of the above steps 110, 120 and 130.

[0174] In an example scenario, Figure 2 As shown, it includes UE (User Equipment) A and UE B. Among them, UE A is used to represent the control information sending end UE B is used to represent the control information receiving end.

[0175] UE A may send the first part of the control information to UE B through the first physical layer channel occupying the first time-frequency resource; may also send first indication information to UE B, where the first indication information is used to indicate the size of the second time-frequency resource, where the second time-frequency resource is the time-frequency resource occupied by the transmission of the second part of the control information; and may send the second part of the control information to UE B through the second physical layer channel occupying the second time-frequency resource;

[0176] Correspondingly, UE B can receive the first part of control information sent by UE A through the first physical layer channel on the first time-frequency resource; it can also receive the first indication information sent by UE A; the first indication information is used to indicate the size of the second time-frequency resource, and the second time-frequency resource is the time-frequency resource occupied by the transmission of the second part of the control information; and can receive the second part of control information sent by UE A through the second physical layer channel on the second time-frequency resource.

[0177] It can be seen from the above embodiments that the control information sending end can send the first part of the control information to the control information receiving end through the first physical layer channel occupying the first time-frequency resource; it can also send the first indication information to the control information receiving end, and the first indication information is used to indicate the size of the second time-frequency resource, and the second time-frequency resource is the time-frequency resource occupied by the transmission of the second part of the control information; and the second part of the control information can be sent to the control information receiving end through the second physical layer channel occupying the second time-frequency resource, thereby realizing that the control information receiving end can receive the second part of the control information according to the indication of the control information sending end without blind detection, and reduces the complexity of blind detection, and also improves the communication quality of direct communication.

[0178] Figure 3 is a flow chart of another control information transmission method according to an exemplary embodiment. The control information transmission method can be used for a control information sending end in direct communication and is established on Figure 1 Based on the method shown in FIG. 1 , when executing step 120, as shown in FIG. Figure 3 As shown, the following steps 310-330 may be included:

[0179] In step 310, the first indication information is added to the first part of the control information.

[0180] In the embodiment of the present disclosure, the first indication information may be a part of the first part of the control information. For example, the first indication information is added to the information field in the first part of the control information.

[0181] In step 320, the first part of control information carrying the first indication information is sent to the control information receiving end through the first physical layer channel occupying the first time-frequency resource.

[0182] In the disclosed embodiment, for the first part of the control information, the first physical layer channel may be PSCCH. That is, the control information transmitter may send the first part of the control information via PSCCH; correspondingly, the control information receiver needs to perform blind detection when receiving the first part of the control information on PSCCH.

[0183] For the second part of control information, the control information receiving end can send the first indication information together with the first part of control information to the control information receiving end, so that the control information receiving end can obtain the first indication information from the first part of control information, determine the size of the second time-frequency resource based on the first indication information, and receive the second part of control information on the second time-frequency resource.

[0184] It can be seen from the above embodiments that when the first indication information is sent to the control information receiving end, the first indication information can be sent to the control information receiving end together with the first part of the control information, so that the control information receiving end can obtain the first indication information from the first part of the control information, and determine the size of the second time-frequency resource according to the first indication information, and receive the second part of the control information on the second time-frequency resource, thereby improving the accuracy of the control information indication and the reliability of the control information receiving end receiving the second part of the control information.

[0185] Figure 4 is a flow chart of another control information transmission method according to an exemplary embodiment. The control information transmission method can be used for a control information sending end in direct communication and is established on Figure 1 Based on the method shown in FIG. 1 , when executing step 120, as shown in FIG. Figure 4 As shown, the following steps 410-420 may be included:

[0186] In step 410, a physical parameter corresponding to the first indication information is determined, and different first indication information corresponds to different physical layer parameters.

[0187] In the embodiment of the present disclosure, the physical parameter corresponding to the first indication information may be used to implicitly indicate the information content of the first indication information.

[0188] In step 420, a first physical layer channel carrying the first part of control information is sent to a control information receiving end using physical parameters corresponding to the first indication information.

[0189] In the disclosed embodiment, for the first part of the control information, the first physical layer channel may be PSCCH. That is, the control information transmitter may send the first part of the control information via PSCCH; correspondingly, the control information receiver needs to perform blind detection when receiving the first part of the control information on PSCCH.

[0190] For the second part of the control information, the control information receiving end can use the physical layer parameters used by the first physical layer channel to implicitly indicate the first indication information, so that the control information receiving end can determine the first indication information by detecting the physical layer parameters used by the first physical layer channel, and determine the size of the second time-frequency resources based on the first indication information, and receive the second part of the control information on the second time-frequency resources.

[0191] In one embodiment, the physical parameter corresponding to the first indication information in the above step 410 may include but is not limited to at least one of the following:

[0192] (4-1) a DMRS (Demodulation Reference Signal) sequence number of the first physical layer channel that transmits the first part of the control information;

[0193] (4-2) The transmission format used when transmitting the first part of the control information.

[0194] It can be seen from the above embodiments that when the first indication information is sent to the control information receiving end, the physical layer parameters used by the first physical layer channel that carries the first part of the control information can be used to implicitly indicate the first indication information. In this way, the control information receiving end can determine the first indication information by detecting the physical layer parameters used by the first physical layer channel, and determine the size of the second time-frequency resources according to the first indication information, and receive the second part of the control information on the second time-frequency resources, thereby improving the flexibility of the control information indication and the efficiency of the control information receiving end in receiving the second part of the control information.

[0195] Figure 5 is a flow chart of a control information transmission method according to an exemplary embodiment, the control information transmission method can be used for a control information receiving end in direct communication, the control information includes a first part of control information and a second part of control information; Figure 5 As shown, the control information transmission method may include the following steps 510-530:

[0196] In step 510, a first portion of control information sent by a control information transmitter is received on a first time-frequency resource through a first physical layer channel.

[0197] In the disclosed embodiment, in order to avoid inconsistent control information, the control information transmitter can divide the control information into two parts for transmission, namely, the first part of the control information and the second part of the control information. The size of the first part of the control information is fixed, and the size of the second part of the control information is not fixed. In this way, the size of the first part of the control information is consistent regardless of unicast, multicast or broadcast, while the size of the second part of the control information is inconsistent (for example, there may be no second part of the information in broadcast). For the control information receiver, the reception of the first part of the control information needs to be blindly detected, while the reception of the second part of the control information may not be blindly detected, but is received according to the size of the second time-frequency resource occupied by the transmission of the second part of the control information indicated by the first indication information, which can reduce the blind detection complexity of the control information receiver.

[0198] The first physical layer channel used to carry the first part of the control information may be PSCCH. That is, the control information transmitter may send the first part of the control information via PSCCH; correspondingly, the control information receiver needs to perform blind detection when receiving the first part of the control information on PSCCH.

[0199] In step 520, first indication information sent by the control information sending end is received; the first indication information is used to indicate the size of the second time-frequency resource, and the second time-frequency resource is the time-frequency resource occupied by the transmission of the second part of the control information.

[0200] In the disclosed embodiment, the second part of the control information may be transmitted using the control channel, i.e., PSCCH, like the first part of the control information, or may be transmitted using the data channel, i.e., PSSCH (Physical Sidelink Control Channel) together with the data. Therefore, before sending the second part of the control information, the control information transmitter needs to notify the control information receiver of the size of the second time-frequency resource occupied by the transmission of the second part of the control information through the first indication information. Correspondingly, after receiving the first indication notification, the control information receiver can determine the size of the second time-frequency resource according to the first indication information, and receive the second part of the control information on the second time-frequency resource.

[0201] In one embodiment, after the above step 520, the following steps may also be included:

[0202] (5-1) Determining a value of a first parameter according to the first indication information;

[0203] (5-2) Calculate the size of the second time-frequency resource based on the first parameter.

[0204] In one embodiment, the value of the first parameter in (5-1) above may be proportional to the size of the second time-frequency resource in (5-2) above.

[0205] In one embodiment, the first parameter in the above (5-1) may include the modulation coding efficiency of the second part of the control information.

[0206] In one embodiment, the second physical layer channel used to transmit the second part of the control information may be a physical layer channel used for data transmission, and the first parameter in the above (5-1) may include a parameter for adjusting the ratio of the coding efficiency of the second part of the control information and the data information.

[0207] In one embodiment, when executing the above (5-1), the first mapping relationship in the base station downlink signaling configuration or the second mapping relationship included in the pre-configuration may be used to implement it, and the implementation process may include:

[0208] (6-1) receiving a base station downlink signaling configuration, obtaining a first mapping relationship between a value of the first parameter and the first indication information, and determining a value of the first parameter using the first mapping relationship; or

[0209] (6-2) Using a second mapping relationship between the value of the first parameter included in the preconfiguration and the first indication information, and using the second mapping relationship to determine the value of the first parameter.

[0210] In step 530, a second portion of control information sent by a control information transmitter is received on a second time-frequency resource through a second physical layer channel.

[0211] In the disclosed embodiment, since the second part of the control information may be transmitted using the control channel, i.e., PSCCH, like the first part of the control information, or may be transmitted using the data channel, i.e., PSSCH, together with data, the second physical layer channel used to transmit the second part of the control information may be PSCCH or PSSCH. That is, the first physical layer channel in the above step 510 and the second physical layer channel in the above step 530 may be the same or different.

[0212] It can be seen from the above embodiments that the control information receiving end can receive the first part of control information sent by the control information sending end through the first physical layer channel on the first time-frequency resource, and can also receive the first indication information sent by the control information sending end; the first indication information is used to indicate the size of the second time-frequency resource, the second time-frequency resource is the time-frequency resource occupied by the transmission of the second part of the control information, and the second part of control information sent by the control information sending end is received through the second physical layer channel on the second time-frequency resource, thereby realizing the reception of the second part of control information according to the indication of the control information sending end without blind detection, reducing the complexity of blind detection, and improving the communication quality of direct communication.

Figure 6 As shown, the following steps 610 may be included:

[0214] In step 610, first indication information is obtained from the first part of control information.

[0215] In the disclosed embodiment, the first indication information may be a part of the first part of the control information. For example, the first indication information is located in the information field of the first part of the control information. Furthermore, since the control information receiving end may send the first indication information together with the first part of the control information to the control information receiving end, the control information receiving end may obtain the first indication information from the first part of the control information, determine the size of the second time-frequency resource according to the first indication information, and receive the second part of the control information on the second time-frequency resource.

[0216] It can be seen from the above embodiments that the first indication information can be directly obtained from the first part of the control information, and the size of the second time-frequency resource can be determined according to the first indication information, and the second part of the control information can be received on the second time-frequency resource, thereby improving the accuracy of the control information indication and the reliability of receiving the second part of the control information.

[0219] In the disclosed embodiment, for the first part of the control information, the first physical layer channel may be PSCCH. Furthermore, since the control information receiving end may use the physical layer parameters used by the first physical layer channel to implicitly indicate the first indication information, the control information receiving end may determine the first indication information by detecting the physical layer parameters used by the first physical layer channel, determine the size of the second time-frequency resource according to the first indication information, and receive the second part of the control information on the second time-frequency resource.

[0223] In step 720, first indication information is determined according to a physical layer parameter used by the first physical layer channel, and different physical layer parameters correspond to different first indication information.

[0224] It can be seen from the above embodiments that the first indication information can be determined by detecting the physical layer parameters used by the first physical layer channel, and the size of the second time-frequency resources can be determined based on the first indication information, and the second part of the control information can be received on the second time-frequency resources, thereby improving the flexibility of the control information indication and the efficiency of receiving the second part of the control information.
