[0039] Before introducing the method for determining the feedback usage resources provided in the embodiments of the present application in detail, the related communication technologies involved in the present application will be described.

[0040] 1. Related communication concepts

[0041] Management node: The node that sends data scheduling information in a vehicle-to-vehicle wireless short-range communication system.

[0042] Terminal node: The node that receives data scheduling information in a vehicle-to-vehicle wireless short-range communication system and sends data according to the data scheduling information.

[0043] G link (G link): The communication link from the management node to the terminal node. This link can carry data channels, control channels, broadcast channels, synchronization signals, etc. from the management node to the terminal node.

[0044] T link (T link): The communication link from the terminal node to the management node. This link can carry data channels, access channels, etc. from the terminal node to the management node.

[0045] 2. Protocol stack architecture of the vehicle-to-vehicle wireless short-range communication system

[0046] The protocol stack architecture of the vehicle-to-vehicle wireless short-range communication system is as Figure 2 shown. Among them, the access layer specifically includes the data link layer and the physical layer. The physical layer uses the transmission medium to provide a physical connection for the data link layer to achieve transparent transmission of bit streams; the data link layer performs functions such as resource management, access control, data segmentation, concatenation, and reordering to ensure reliable data transmission. In order to achieve secure and efficient data transmission between the management node and the terminal node in the access layer, necessary management functions and security functions such as connection management, authentication, security mechanism update, and resource scheduling are required between the management node and the terminal node. Information can be exchanged between layers, and the lower layer provides services for the upper layer.

[0047] 3. Physical Layer

[0048] (1) General Description

[0049] The physical layer provides a data transmission service to the data link layer. Among them, the physical layer defines a physical resource and frame structure based on Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP - OFDM) waveform and Time Division Duplex (TDD), and on this basis, defines the physical layer signals, physical layer control information, and physical layer data information transmitted in the physical layer link.

[0050] The physical layer signals are transmitted using a set of a series of resource elements, which are not used to carry information from higher layers. The physical layer signals include G - link physical layer signals and T - link physical layer signals. Among them, the G - link physical layer signals represent the physical layer signals applicable to the G - link; the T - link physical layer signals represent the physical layer signals applicable to the T - link.

[0051] The physical layer control information is transmitted using a set of a series of resource elements and is used to carry control information from higher layers. The physical layer control information includes G - link physical layer control information and T - link physical layer control information. Among them, the G - link physical layer control information represents the physical layer control information applicable to the G - link; the T - link physical layer control information represents the physical layer control information applicable to the T - link. At the same time, the G - link physical layer control information includes broadcast information and G - link control information; the T - link physical layer control information includes access information and T - link control information.

[0052] The physical layer data information is transmitted using a set of a series of resource elements and is used to carry data information from higher layers. Among them, the data information from higher layers includes higher - layer signaling.

[0053] Specifically, the physical layer signals, physical layer control information, and physical layer data information defined by the physical layer are shown in Table 1.

[0054] Table 1

[0055]

[0056] It should be noted that all kinds of time lengths in the physical layer are multiples of the basic time unit T S . The basic time unit T S is defined as T S = 1 / fs, where the physical layer reference frequency fs is 30.72 MHz.

[0057] (2) Frame Structure and Physical Resources

[0058] 1) Waveform and Symbol

[0059] The physical layer signal, physical layer control information, and physical layer data information are transmitted based on the CP-OFDM waveform with a subcarrier spacing of Δf = fs / 64 = 480 kHz. Without confusion, in this application, the symbol is used as an abbreviation for the CP-OFDM symbol.

[0060] 2) Wireless frame structure

[0061] The G-link transmission and T-link transmission use different symbols in the wireless frame. The symbol used for G-link transmission is called the G symbol, and the symbol used for T-link transmission is called the T symbol. A wireless frame consists of one or more G symbols, a first switching interval (GAP1), one or more T symbols, and a second switching interval (GAP2) in sequence; or a wireless frame consists of one or more T symbols, a first switching interval (GAP1), one or more G symbols, and a second switching interval (GAP2) in sequence; or a wireless frame consists of multiple symbols and an inter-frame interval time GT in sequence. A wireless frame contains symbols, numbered #0, #1, …, The time lengths of GAP1 and GAP2 are T GAP .

[0062] For the case of a normal cyclic prefix: When the wireless frame contains GAP1 and GAP2, T GAP = 44·T s , and according to the different numbers and positions of G symbols and T symbols, the wireless frame structure has 14 structures.

[0063] For the case of an extended cyclic prefix: When the wireless frame contains GAP1 and GAP2, T GAP = 47·T s , and according to the different numbers and positions of G symbols and T symbols, the wireless frame structure has 12 structures.

[0064] 3) Half Super Frame and Super Frame

[0065] The Half Super Frame is defined as the time length composed of 24 wireless frames in the vehicle-mounted wireless short-range communication system. That is to say, every 24 wireless frames form a Half Super Frame, and the time length of each Half Super Frame is 0.5 ms.

[0066] The Super Frame is defined as the time length composed of 48 wireless frames in the vehicle-mounted wireless short-range communication system. That is to say, every 2 Half Super Frames form a Super Frame, and the time length of each Super Frame is 1 ms. Therefore, a Super Frame contains 48 wireless frames, numbered #0, #1, …, #47 in sequence from front to back in time.

[0067] 4) Carrier

[0068] A carrier consists of 39 consecutive sub - carriers. These 39 sub - carriers are numbered #0, #1, …, #38 in ascending order of their corresponding frequencies. Among them, the #19 sub - carrier is the DC sub - carrier. Except for the DC sub - carrier, the other 38 sub - carriers are called valid sub - carriers. Additionally, a symbol can contain 39 sub - carriers.

[0069] In a carrier, every 4 sub - carriers form 1 first - level granularity sub - carrier group, with a total of 10 first - level granularity sub - carrier groups. These 10 first - level granularity sub - carrier groups are numbered #0, #1, …, #9 in ascending order of their corresponding frequencies. Among them, the #4 first - level granularity sub - carrier group contains the DC sub - carrier, the #9 first - level granularity sub - carrier group contains 3 valid sub - carriers, and the other first - level granularity sub - carrier groups each contain 4 valid sub - carriers.

[0070] In a carrier, every 8 sub - carriers form 1 second - level granularity sub - carrier group, with a total of 5 second - level granularity sub - carrier groups. These 5 second - level granularity sub - carrier groups are numbered #0, #1, …, #4 in ascending order of their corresponding frequencies. Among them, the #2 second - level granularity sub - carrier group contains the DC sub - carrier, the #4 second - level granularity sub - carrier group contains 7 valid sub - carriers, and the other second - level granularity sub - carrier groups each contain 8 valid sub - carriers.

[0071] The management node uses one or more carriers simultaneously. For the case where the management node uses multiple carriers simultaneously, the management node transmits the physical layer signals and physical layer control information applicable to each carrier it uses, and allows the terminal node to assume that the multiple carriers used by the management node are synchronized.

[0072] 5) Communication Domain

[0073] On a carrier used by a management node, the resource set composed of the synchronization signal, broadcast information, the resource for G - link control information sent by the management node, and the resources that the management node can schedule and configure is called the communication domain of the management node, and the management node is called the management node of this communication domain.

[0074] In addition, a communication domain consists of the G - link and the T - link of this communication domain. Among them, the G - link of a communication domain is defined as the resource for the management node of this communication domain to send physical layer signals, physical layer control information, and physical layer data information; the T - link of a communication domain is defined as the resource for the management node of this communication domain to receive physical layer signals, physical layer control information, and physical layer data information.

[0075] 6) G - link Control Information

[0076] The transmission resources for G-link control information include common resources and dedicated resources specific to the T-node. Among them, the control information that can be transmitted in the common resources of G-link control information includes: the indication information of the transmission overhead resources for the second type of data information (69 bits), the indication information of the system message resources (58 bits), the activation / deactivation information of the transmission resources for the first type of data information (58 bits), and the dynamic scheduling information for the transmission of the second type of data information (58 bits or 69 bits). The control information that can be transmitted in the dedicated resources specific to the T-node of G-link control information includes: the activation / deactivation information of the transmission resources for the first type of data information (58 bits), and the dynamic scheduling information for the transmission of the second type of data information (58 bits or 69 bits).

[0077] The T-node uses the common resources and dedicated resources specific to the T-node of G-link control information to receive the dynamic scheduling information for the transmission of the second type of data information.

[0078] At most 1 common resource for G-link control information is configured within 1 superframe. Within the common resources, the T-node blindly detects control information of two lengths, 69 bits and 58 bits, and the maximum number of blind detections for each length is 4.

[0079] At most 8 dedicated resources specific to the T-node of G-link control information are configured within 1 superframe. When the T-node is configured for code block group (CBG) retransmission or CBG hybrid retransmission, the T-node blindly detects control information of 69-bit length within each configured dedicated resource specific to the T-node; when the T-node is configured for transport block (TB)-based retransmission, the T-node blindly detects control information of 58-bit length within each configured dedicated resource specific to the T-node. For control information of each length, the maximum number of blind detections by the T-node within 1 superframe is 32.

[0080] 7) Dynamic scheduling data control information

[0081] The dynamic scheduling data control information may include the dynamic scheduling information for the transmission of the second type of data information.

[0082] When the scheduled T-node supports both TB-based retransmission and CBG-based retransmission, the dynamic scheduling data control information is 69 bits in total. When the scheduled T-node only supports TB-based retransmission, the dynamic scheduling data control information is 59 bits in total.

[0083] It should be noted that the dynamic scheduling data control information (58 bits or 69 bits) includes the following 4-bit information:

[0084] 4 bits: Comb type parameter and starting comb subcarrier group information for ACK feedback. Among them, 0000 represents the comb is 1; 0001 represents the comb is 2 and uses even subcarriers; 0010 represents the comb is 2 and uses odd subcarriers; 0011 represents the comb is 2 and uses all subcarriers; 0100 represents the comb is 4 and uses subcarriers with a remainder of 0 modulo 4; 0101 represents the comb is 4 and uses subcarriers with a remainder of 1 modulo 4; 0110 represents the comb is 4 and uses subcarriers with a remainder of 2 modulo 4; 0111 represents the comb is 4 and uses subcarriers with a remainder of 3 modulo 4; 1000 represents the comb is 4 and uses subcarriers with a remainder of 0 modulo 4 and subcarriers with a remainder of 1 modulo 4; 1001 represents the comb is 4 and uses subcarriers with a remainder of 2 modulo 4 and subcarriers with a remainder of 3 modulo 4; 1010 represents the comb is 4 and uses subcarriers with a remainder of 0 modulo 4, subcarriers with a remainder of 1 modulo 4, and subcarriers with a remainder of 2 modulo 4; 1011 represents the comb is 4 and uses all subcarriers. Other cases are reserved.

[0085] 4. Data Link Layer

[0086] (1) Management Configuration Information

[0087] 1) T-node specific control information resource pool information (ControlResource)

[0088] The T-node specific control information resource pool information is used to indicate a group of resources for blind detection of control information within a superframe composed of 48 radio frames, and the ACK resource pool paired with this control information resource pool.

[0089] Each superframe contains the T-node specific control information resource pool indicated by this T-node specific control information resource pool information, and the ACK resource pool paired with this control information resource pool.

[0090] When the T-node is not configured with this T-node specific control information resource pool, the T-node uses the common control information resource pool in the communication domain to detect control information and uses the first ACK resource pool in the ACK resource pool set to feedback ACK information.

[0091] 2) T-node specific ACK comb information (DedicatedACK-ResourceCombConf)

[0092] The T-node specific ACK comb information is used to indicate the resources used for ACK feedback in the ACK resource pool. 0000 represents a comb of 1; 0001 represents a comb of 2 and uses even subcarriers; 0010 represents a comb of 2 and uses odd subcarriers; 0011 represents a comb of 2 and uses all subcarriers; 0100 represents a comb of 4 and uses subcarriers with a modulo 4 of 0; 0101 represents a comb of 4 and uses subcarriers with a modulo 4 of 1; 0110 represents a comb of 4 and uses subcarriers with a modulo 4 of 2; 0111 represents a comb of 4 and uses subcarriers with a modulo 4 of 3; 1000 represents a comb of 4 and uses subcarriers with a modulo 4 of 0 and a modulo 4 of 1; 1001 represents a comb of 4 and uses subcarriers with a modulo 4 of 2 and a modulo 4 of 3; 1010 represents a comb of 4 and uses subcarriers with a modulo 4 of 0, a modulo 4 of 1, and a modulo 4 of 2; 1011 represents a comb of 4 and uses all subcarriers; 1100 represents determining the comb information according to the dynamic scheduling data control information.

[0093] In summary, in the current protocol standards for vehicle-to-vehicle short-range wireless communication, when the T-node is not configured with a specific control information resource pool, the T-node uses the common control information resource pool in the communication domain to detect control information and uses the first ACK resource pool in the ACK resource pool set to feedback ACK information. However, the current protocol standards do not specify the information on the resources used for ACK feedback in this first ACK resource pool.

[0094] Combined with the above description, the embodiment of the present application provides a flowchart of a method for determining the resources used for feedback. Please refer to Figure 3 . The method includes:

[0095] S310. The terminal obtains configuration information.

[0096] Specifically, for the terminal to obtain configuration information, the following operations may be included: The terminal receives control information from the management device to obtain configuration information; or, the terminal obtains pre-configured or pre-defined configuration information. It can be understood that the configuration information can be obtained by the terminal from the network device, and the configuration information is carried in the control information; the configuration information can also be pre-configured, pre-defined, or specified by the protocol standard, and no specific limitation is made thereto.

[0097] Further, if the configuration information is sent by the management device, the terminal does not expect that the management device has not configured this configuration information.

[0098] Furthermore, the control information may include at least one of the following: physical layer control information, G link control information, dynamic scheduling data control information, communication domain common control information, communication domain specific or dedicated control information, dynamic scheduling information for the second type of data information transmission (58 bits or 69 bits), and dynamic scheduling information. It should be noted that the specific descriptions of the above various types of control information can be found in the descriptions of the above "physical layer" and "data link layer" content, and will not be elaborated here.

[0099] Specifically, the configuration information may include at least one of the following: the comb type parameter of ACK or NACK feedback, the starting comb subcarrier group information of ACK or NACK feedback, and the comb subcarrier group information of ACK or NACK feedback.

[0100] To facilitate the understanding of the configuration information in the embodiments of the present application, the comb type parameter of ACK or NACK feedback, the starting comb subcarrier group information of ACK or NACK feedback, and the comb subcarrier group information of ACK or NACK feedback in the configuration information will be specifically described below.

[0101] Since the protocol standard for vehicle-mounted wireless short-range communication defines that the signal transmission can be either in the continuous subcarrier transmission mode or in the comb-shaped subcarrier transmission mode (or, the spaced subcarrier transmission mode). Therefore, the comb type parameter of ACK or NACK feedback in the embodiments of the present application can be used to indicate whether the resources used for ACK feedback information or NACK feedback information are in the continuous subcarrier mode or in the comb-shaped subcarrier mode. Among them, the comb type parameter can indicate that the comb is 1, the comb is 2, the comb is 4, etc. At the same time, comb being 1 can represent the continuous subcarrier mode; comb being 2 can represent the comb-shaped subcarrier mode; comb being 4 can represent the comb-shaped subcarrier mode.

[0102] Then, through the content of the above "carrier", it can be known that one carrier consists of 39 consecutive subcarriers, which are numbered #0, #1, …, #38 in sequence, and a subcarrier group consists of at least one subcarrier. Therefore, the starting comb subcarrier group information of ACK or NACK feedback in the embodiments of the present application can be used to indicate which numbered subcarriers the resources used for ACK feedback information or NACK feedback information consist of. Similarly, the comb subcarrier group information of ACK or NACK feedback can be used to indicate which numbered subcarriers the resources used for ACK feedback information or NACK feedback information consist of.

[0103] For example, the starting comb subcarrier group information or the comb subcarrier group information can be used to indicate even subcarriers, odd subcarriers, all subcarriers, subcarriers with a modulo-4 value of 0, subcarriers with a modulo-4 value of 1, subcarriers with a modulo-4 value of 2, subcarriers with a modulo-4 value of 3, subcarriers with a modulo-4 value of 0 and subcarriers with a modulo-4 value of 1, subcarriers with a modulo-4 value of 2 and subcarriers with a modulo-4 value of 3, subcarriers with a modulo-4 value of 0, subcarriers with a modulo-4 value of 1, and subcarriers with a modulo-4 value of 2, etc.

[0104] Among them, the even subcarriers can be understood as being composed of subcarriers with even numbers, such as subcarrier #2, subcarrier #4, etc.; the odd subcarriers can be understood as being composed of subcarriers with odd numbers, such as subcarrier #1 and subcarrier #3, etc.; the subcarriers with a modulo-4 value of 0 can be understood as being composed of subcarriers with a modulo-4 value of 0, such as subcarrier #0, subcarrier #4, and subcarrier #8, etc.; the subcarriers with a modulo-4 value of 1 can be understood as being composed of subcarriers with a modulo-4 value of 1, such as subcarrier #1, subcarrier #5, and subcarrier #9, etc.; the subcarriers with a modulo-4 value of 2 and the subcarriers with a modulo-4 value of 3 can be understood as being composed of subcarriers with a modulo-4 value of 2 and subcarriers with a modulo-4 value of 3, such as subcarrier #2, subcarrier #3, subcarrier #6, and subcarrier #7, etc. The rest can be known by analogy and will not be elaborated here.

[0105] Specifically, the configuration information can be M-bit information, where M is an integer. The following describes the possible implementation methods of this M-bit information.

[0106] Method 1:

[0107] Furthermore, the M-bit information can be presented in a coding combination method or a bitmap method. It can be understood that the configuration information can be M-bit information, and this M-bit information can be used to indicate the resources used for ACK or NACK feedback in a coding combination method or a bitmap method.

[0108] For example, if M is 4, that is, the configuration information is 4-bit information. When this 4-bit information is used to indicate the resources used for ACK or NACK feedback in a coding combination method or a bitmap method, 0000 represents a comb of 1, 0001 represents a comb of 2 and uses even subcarriers, 0010 represents a comb of 2 and uses odd subcarriers, etc., which is the same as the "4-bit" description in the content of "dynamic scheduling data control information" above and will not be elaborated here.

[0109] Method 2:

[0110] Further, N bits in the M-bit information can be used to represent the comb type parameter, and the remaining bits in the M-bit information except the N bits can be used to represent the starting comb subcarrier group information or the comb subcarrier group information; alternatively, the remaining bits in the M-bit information except the N bits are used as reserved bits. Here, N is an integer less than M. It should be noted that compared with "Mode 1", "Mode 2" has characteristics such as large signaling overhead.

[0111] For example, in order to implement all cases where the above "Mode 1" uses 4-bit information to indicate the resources for ACK or NACK feedback, M can take the value of 5. That is to say, the configuration information is 5-bit information, and the first 2 bits in the 5-bit information are used to represent the comb type parameter, while the remaining bits are used to represent the starting comb subcarrier group information or the comb subcarrier group information; alternatively, the remaining bits are used as reserved bits. Here, the first 2 bits being "00" represents that the comb is 1; the first 2 bits being "01" represents that the comb is 2; the first 2 bits being "10" represents that the comb is 4. At this time, the 5-bit information being "00xxx" represents that the comb is 1, and "x" represents the reserved bit; the 5-bit information being "01000" represents that the comb is 2 and the even subcarriers are used; the 5-bit information being "01001" represents that the comb is 2 and the odd subcarriers are used; the 5-bit information being "01010" represents that the comb is 2 and all subcarriers are used; the 5-bit information being "10 000" represents that the comb is 4 and the subcarriers with a modulo 4 value of 0 are used; the 5-bit information being "10 001" represents that the comb is 4 and the subcarriers with a modulo 4 value of 1 are used. The rest can be known by analogy and will not be elaborated here. It can be seen that compared with the 4 bits in "Mode 1", the 5 bits in "Mode 2" have characteristics such as large signaling overhead.

[0112] S320. The terminal determines the resources for feedback of the acknowledgement ACK or non-acknowledgement NACK in the first resource pool according to the configuration information.

[0113] Among them, the first resource pool can be used to represent a group of resources for feedback of ACK or NACK information within a superframe composed of 48 radio frames.

[0114] It should be noted that according to the content of the above "frame structure and physical resources", one superframe in the embodiments of the present application can include 48 radio frames, one radio frame can include 7 or 8 CP-OFDM symbols, and one symbol can include 39 subcarriers. Therefore, the embodiments of the present application represent the first resource pool as a group of resources for feedback of ACK or NACK information within a superframe, and the minimum granularity of the first resource pool is a subcarrier.

[0115] Further, it should be noted that the resources used for ACK or NACK feedback in the first resource pool can be understood as whether the resources in the first resource pool used for feedback of ACK feedback information or NACK feedback information adopt a continuous subcarrier mode or a comb-shaped subcarrier mode, and which numbered subcarriers the resources in the first resource pool used for feedback of ACK feedback information or NACK feedback information consist of.

[0116] Further, it should be noted that each superframe contains this first resource pool.

[0117] Specifically, the resources used for ACK or NACK feedback in the first resource pool can include at least one of the following: comb with 1 tooth, comb with 2 teeth and using even subcarriers, comb with 2 teeth and using odd subcarriers, comb with 2 teeth and using all subcarriers, comb with 4 teeth and using subcarriers with a modulo 4 value of 0, comb with 4 teeth and using subcarriers with a modulo 4 value of 1, comb with 4 teeth and using subcarriers with a modulo 4 value of 2, comb with 4 teeth and using subcarriers with a modulo 4 value of 3, comb with 4 teeth and using subcarriers with a modulo 4 value of 0 and subcarriers with a modulo 4 value of 1, comb with 4 teeth and using subcarriers with a modulo 4 value of 2 and subcarriers with a modulo 4 value of 3, comb with 4 teeth and using subcarriers with a modulo 4 value of, subcarriers with a modulo 4 value of 1 and subcarriers with a modulo 4 value of 2.

[0118] It should be noted that from the above description, when the configuration information includes the comb type parameter for ACK or NACK feedback and the starting comb subcarrier group information, and the comb type parameter indicates a comb and the starting comb subcarrier group information indicates a comb with 2 teeth and using even subcarriers, the resources used for ACK or NACK feedback in the first resource pool determined by the terminal according to the configuration information are the resources in the first resource pool with a comb of 2 teeth and using even subcarriers. The same applies to the rest and will not be elaborated here.

[0119] Furthermore, the first resource pool can include the first ACK resource pool in the ACK resource pool set; wherein, the ACK resource pool set can be used to represent at least one set of resource pools for feedback of ACK or NACK information within a superframe composed of 48 radio frames.

[0120] Furthermore, the ACK resource pool set can include the ACK resource pool set paired with the common control information resource pool in the communication domain.

[0121] Furthermore, the ACK resource pool set can be configured by the communication domain system message (DomainSysInfo). The communication domain system message is broadcast by the management device in the communication domain to the terminals in its communication domain.

[0122] Combined with the description of the above ACK resource pool set and the content of the above "T-node specific control information resource pool information", it can be seen that when the terminal is not configured with this T-node specific control information resource pool, the terminal uses the common control information resource pool in the communication domain to detect control information and uses the first ACK resource pool in the ACK resource pool set to feedback ACK information. Therefore, in order to simultaneously solve the problem that the current protocol standard does not specify the information on the resources used for ACK feedback in this first ACK resource pool, the embodiment of the present application configures the resources used for ACK feedback in this first ACK resource pool through configuration information.

[0123] It can be seen that in the embodiment of the present application, the terminal determines the resources used for ACK or NACK feedback in the first resource pool by obtaining configuration information, which is conducive to configuring the resources used for ACK or NACK feedback in the first resource pool for the terminal. In addition, since the first resource pool is used to represent a set of resources for feedbacking ACK or NACK information within a superframe composed of 48 radio frames, and the minimum granularity of this first resource pool is a subcarrier, the embodiment of the present application realizes determining whether the resources in the first resource pool used for feedbacking ACK feedback information or NACK feedback information are in a continuous subcarrier manner or in a comb-like subcarrier manner through configuration information, and which numbered subcarriers the resources in the first resource pool used for feedbacking ACK feedback information or NACK feedback information consist of.

[0124] Consistent with the above embodiment, the embodiment of the present application provides a schematic flow chart of another method for determining the resources used for feedback. Please refer to Figure 4 . This method includes:

[0127] Specifically, the configuration information is transmitted by control information.

[0128] Further, in the Figure 4 shown embodiment, since the configuration information is sent by the management device, the terminal does not expect that the management device does not configure this configuration information.

[0129] Further, the control information may include at least one of the following: physical layer control information, G-link control information, dynamic scheduling data control information, communication domain common control information, communication domain specific or dedicated control information, dynamic scheduling information for the transmission of the second type of data information (58 bits or 69 bits), and dynamic scheduling information.

[0130] Specifically, the configuration information may include at least one of the following: the comb type parameter of ACK or NACK feedback, the starting comb subcarrier group information of ACK or NACK feedback, and the comb subcarrier group information of ACK or NACK feedback.

[0131] Specifically, the resources used for ACK or NACK feedback in the first resource pool include at least one of the following: comb 1, comb 2 and using even subcarriers, comb 2 and using odd subcarriers, comb 2 and using all subcarriers, comb 4 and using subcarriers with a modulo 4 value of 0, comb 4 and using subcarriers with a modulo 4 value of 1, comb 4 and using subcarriers with a modulo 4 value of 2, comb 4 and using subcarriers with a modulo 4 value of 3, comb 4 and using subcarriers with a modulo 4 value of 0 and a modulo 4 value of 1, comb 4 and using subcarriers with a modulo 4 value of 2 and a modulo 4 value of 3, comb 4 and using subcarriers with a modulo 4 value of 0, a modulo 4 value of 1, and a modulo 4 value of 2.

[0132] Specifically, the first resource pool may include the first ACK resource pool in the ACK resource pool set; wherein, the ACK resource pool set may be used to represent at least one set of resource pools for feedback ACK information within a superframe composed of 48 radio frames.

[0133] Further, the ACK resource pool set may include the ACK resource pool set paired with the communication domain common control information resource pool.

Then, the terminal obtains the configuration information and determines the resources for ACK or NACK feedback in the first resource pool according to the configuration information. Since the configuration information is sent from the management device to the terminal, it is beneficial to implement the configuration of the resources for ACK or NACK feedback in the first resource pool from the management device to the terminal. In addition, since the first resource pool is used to represent a set of resources for feedback ACK or NACK information within a superframe composed of 48 radio frames, and the minimum granularity of the first resource pool is a subcarrier, the embodiments of the present application implement determining whether the resources in the first resource pool used for feedback of ACK feedback information or NACK feedback information are in a continuous subcarrier manner or a comb-like subcarrier manner through the configuration information, and which numbered subcarriers the resources in the first resource pool used for feedback of ACK feedback information or NACK feedback information consist of.
