TABLE 1

It should be noted that the various time lengths of the physical layer are basic time units T_SMultiples of (a). Basic time unit T_SIs defined as T _S1/fs, wherein physicalThe layer reference frequency fs is 30.72 MHz.

(2) Frame structure and physical resources

1) Waveform and symbol

The physical layer signal, physical layer control information and physical layer data information are transmitted based on a CP-OFDM waveform with a subcarrier spacing Δ f-fs/64-480 kHz. In the case of no confusion, the symbols are used as short for CP-OFDM symbols in the application.

2) Wireless frame structure

The G link transmission and the T link transmission use different symbols in a wireless frame, the symbols used by the G link transmission are called G symbols, and the symbols used by the T link transmission are called T symbols. One radio 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 one radio 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 one radio frame is sequentially composed of a plurality of symbols and an inter-frame space time GT. A radio frame comprises

The symbols are numbered #0, #1, …,

GAP1 and GAP2 with a time span of T_GAP。

For the case of a conventional cyclic prefix:

when the wireless frame includes GAP1 and GAP2, T_GAP＝44·T_sThe radio frame structure has 14 structures according to the number and positions of the G symbols and the T symbols.

For the case of extended cyclic prefix:

when the wireless frame includes GAP1 and GAP2, T_GAP＝47·T_sAccording to the difference of the number and position of G symbol and T symbol, the radio frame structureThere are 12 structures.

3) Semi-superframe (Half Super Frame) and superframe

A half superframe is defined as a time length consisting of 24 radio frames in the vehicle-mounted wireless short-range communication system. That is, each 24 radio frames constitutes one half superframe, and the time length of each half superframe is 0.5 ms.

A superframe is defined as a time length composed of 48 wireless frames in an on-vehicle wireless short-range communication system. That is, one superframe is composed every 2 half superframes, and the time length of each superframe is 1 ms. Therefore, one superframe includes 48 radio frames, which are numbered #0, #1, # …, #47 sequentially from front to back.

4) Carrier wave

One carrier consists of 39 consecutive subcarriers, and the 39 subcarriers are numbered #0, #1, # …, #38 in order from the lower to the higher of the corresponding frequencies. Here, the #19 subcarrier is a DC subcarrier, and the other 38 subcarriers except the DC subcarrier are referred to as active subcarriers. In addition, one symbol may contain 39 subcarriers.

Every 4 subcarriers in one carrier form 1 first-granularity subcarrier group, and the 10 first-granularity subcarrier groups are numbered as #0, #1, # … and #9 in sequence from low to high according to the corresponding frequency. Wherein, the #4 first granularity subcarrier group includes DC subcarriers, the #9 first granularity subcarrier group includes 3 effective subcarriers, and the other first granularity subcarrier groups all include 4 effective subcarriers.

Every 8 subcarriers in one carrier form 1 second-granularity subcarrier group, and 5 second-granularity subcarrier groups are counted as #0, #1, # … and #4 in sequence from low to high in corresponding frequency. Wherein, the #2 second-granularity subcarrier group includes DC subcarriers, the #4 second-granularity subcarrier group includes 7 effective subcarriers, and the other second-granularity subcarrier groups all include 8 effective subcarriers.

The management node uses one or more carriers simultaneously. For the case where the management node uses a plurality of carriers simultaneously, the management node transmits physical layer signals and physical layer control information applicable to the carrier at each carrier used, and allows the terminal node to assume that the plurality of carriers used by the management node are synchronized.

5) Communication Domain (Communication Domain)

On a carrier used by a management node, the management node sends resources of synchronization signals, broadcast information and G link control information, and a resource set consisting of the resources which can be scheduled and configured by the management node is called a communication domain of the management node, and the management node is called a management node of the communication domain.

In addition, one communication domain is composed of a G-link of the communication domain and a T-link of the communication domain. The G link of one communication domain is defined as a resource for a management node of the 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 a resource for a management node of the communication domain to receive physical layer signals, physical layer control information and physical layer data information.

The control information that can be transmitted in the common resource of the G link control information includes: the second type data information transmits overhead resource indication information (69 bits), indication information of system message resources (58 bits), activation and deactivation information of first type data information transmission resources (58 bits) and dynamic scheduling information of second type data information transmission (58 bits or 69 bits). The control information that can be transmitted in the T node specific resource of the G link control information includes: the first type data information transmission resource activation deactivation information (58 bits) and the second type data information transmission dynamic scheduling information (58 bits or 69 bits).

The T node receives the dynamic scheduling information of the second type data information transmission by using the common resource of the G link control information and the specific resource of the T node.

A maximum of 1 common resource of G link control information is configured within 1 superframe. In the common resource, the T node blindly detects control information with two lengths of 69 bits and 58 bits, and the maximum blind detection times of each length is 4.

A maximum of 8T-node specific resources for G-link control information are configured within 1 superframe. When a T node is configured to perform Code Block Group (CBG) retransmission or CBG hybrid retransmission, the T node blindly detects control information of 69 bit length in each configured T node specific resource; when a T-node is configured to perform Transport Block (TB) based retransmission, the T-node blindly detects control information of a 58-bit length within each configured T-node specific resource. For each length of control information, the maximum number of times of blind detection of the T node in 1 superframe is 32.

7) Dynamically scheduling data control information

The dynamically scheduled data control information may include dynamically scheduled information for transmission of the second type of data information.

When the scheduled T node supports TB-based retransmission and CBG-based retransmission, the data control information is dynamically scheduled with a total of 69 bits. When the scheduled T node supports only TB-based retransmission, the dynamic scheduling data control information has 59 bits in total.

It should be noted that the dynamic scheduling data control information (58 bits or 69 bits) includes the following 4 bits of information:

4 bits: and the comb type parameter and the initial comb subcarrier group information fed back by the ACK. Wherein 0000 represents comb teeth of 1; 0001 represents comb 2 and uses even number of subcarriers; 0010 represents comb 2 and uses odd number of subcarriers; 0011 represents comb 2 and uses all subcarriers; 0100 represents a 4 comb and uses a modulo-4 0 subcarrier; 0101 represents a subcarrier with 4 comb teeth and modulo 4 is used as 1; 0110 represents a subcarrier with a comb of 4 and modulo 4 of 2; 0111 represents a subcarrier with a comb of 4 and modulo 4 of 3; 1000 represents a subcarrier with a comb of 4 and using modulo 4 0 and modulo 4 of 1; 1001 represents a subcarrier with comb 4 and using modulo 42 and modulo 4 3; 1010 represents a subcarrier with comb 4 and using modulo 4 0, modulo 41, and modulo 4 2; 1011 represents a comb of 4 and all subcarriers are used. Other cases are reserved.

4. Data link layer

(1) Managing configuration information

1) T node specific control information resource pool information (ControlResource)

The T node specific control information resource pool information is used to indicate 1 set of resources used to blindly detect control information within a superframe consisting of 48 radio frames, and an ACK resource pool paired with the control information resource pool.

And each superframe comprises a T node specific control information resource pool indicated by the T node specific control information resource pool information and an ACK resource pool matched with the control information resource pool.

And when the T node is not configured with the T node specific control information resource pool, the T node detects the control information by using the communication domain common control information resource pool and feeds back the ACK information by using the first ACK resource pool in the ACK resource pool set.

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

The T node specific ACK comb information is used for indicating ACK feedback in the ACK resource pool to use resources. 0000 represents comb 1; 0001 represents comb 2 and uses even number of subcarriers; 0010 represents comb 2 and uses odd number of subcarriers; 0011 represents comb 2 and uses all subcarriers; 0100 represents a 4 comb and uses a modulo-4 0 subcarrier; 0101 represents a subcarrier with 4 comb teeth and modulo 4 is used as 1; 0110 represents a subcarrier with a comb of 4 and modulo 4 of 2; 0111 represents a subcarrier with a comb of 4 and modulo 4 of 3; 1000 represents a subcarrier with a comb of 4 and using modulo 4 0 and modulo 4 of 1; 1001 represents a subcarrier with comb 4 and using modulo 42 and modulo 4 3; 1010 represents a subcarrier with comb 4 and using modulo 4 0, modulo 41, and modulo 4 2; 1011 represents a comb of 4 and all subcarriers are used; 1100 represents determining comb information from dynamically scheduled data control information.

In summary, in the current protocol standard for vehicle-mounted short-range wireless communication, when a T node is not configured with a specific control information resource pool, the T node detects control information using a communication domain common control information resource pool and feeds back ACK information using a first ACK resource pool in an ACK resource pool set. However, current protocol standards do not specify that ACK feedback in this first pool of ACK resources uses information of resources.

In conjunction with the above description, an embodiment of the present application provides a flowchart illustrating a method for determining a feedback use resource, please refer to fig. 3. The method comprises the following steps:

s310, the terminal acquires configuration information.

Specifically, the terminal acquiring the configuration information may include the following operations: the terminal receives control information from the management equipment to acquire configuration information; alternatively, the terminal acquires pre-configured or pre-defined configuration information. It is understood that the configuration information may be obtained by the terminal from the network device, and the configuration information is carried in the control information; the configuration information may also be preconfigured, predefined, or specified by a protocol standard, which is not particularly limited.

Further, if the configuration information is issued by the management apparatus, the terminal does not expect the management apparatus not to configure the configuration information.

Further, the control information may include at least one of: physical layer control information, G-link control information, dynamic scheduling data control information, communication domain common control information, communication domain specific or dedicated (dedicated) control information, dynamic scheduling information (58 bits or 69 bits) for second type data information transmission, dynamic scheduling information. It should be noted that, the above various types of control information are specifically described in the content of the "physical layer" and the "data link layer," and are not described herein again.

Specifically, the configuration information may include at least one of: the comb type parameter fed back by ACK or NACK, the initial comb subcarrier group information fed back by ACK or NACK, and the comb subcarrier group information fed back by ACK or NACK.

In order to facilitate understanding of the configuration information in the embodiment of the present application, a comb type parameter for ACK or NACK feedback, starting comb subcarrier group information for ACK or NACK feedback, and comb subcarrier group information for ACK or NACK feedback in the configuration information are specifically described below.

The protocol standard for the in-vehicle wireless short-range communication defines that the signal transmission may be performed by a continuous subcarrier transmission method or a comb-shaped subcarrier transmission method (or an interval subcarrier transmission method). Therefore, the comb-type parameter for ACK or NACK feedback in the embodiment of the present application may be used to indicate whether the resource used by the ACK feedback information or the NACK feedback information is in a continuous subcarrier manner or in a comb-shaped subcarrier manner. Wherein, the comb type parameter may indicate that the comb is 1, the comb is 2, the comb is 4, and so on. Meanwhile, the comb teeth of 1 can represent that a continuous subcarrier mode is adopted; the comb teeth of 2 can represent that a comb tooth-shaped subcarrier mode is adopted; a comb 4 may indicate that a comb subcarrier scheme is used.

Then, as can be seen from the above description of "carrier", one carrier is composed of 39 consecutive subcarriers, and is numbered #0, #1, # …, #38 in this order, and the subcarrier group is composed of at least one subcarrier. Therefore, the starting comb subcarrier group information of ACK or NACK feedback in the embodiment of the present application may be used to indicate which numbered subcarriers the resources used by the ACK feedback information or NACK feedback information are composed of. Likewise, the comb subcarrier group information for ACK or NACK feedback may be used to indicate which numbered subcarriers the resources used by the ACK feedback information or NACK feedback information are composed of.

For example, the start comb subcarrier group information or the comb subcarrier group information may be used to indicate even subcarriers, odd subcarriers, all subcarriers, subcarriers whose values are modulo 4 are 0, subcarriers whose values are modulo 4 are 1, subcarriers whose values are modulo 4 are 2, subcarriers whose values are modulo 4 are 3, subcarriers whose values are modulo 4 are 0 and 1, subcarriers whose values are modulo 4 are 2 and 3, subcarriers whose values are modulo 4 are 0, subcarriers whose values are modulo 4 are 1 and 2, and the like.

Wherein, the even subcarriers can be understood as being composed of subcarriers numbered as even numbers, such as #2 subcarriers, #4 subcarriers, etc.; the odd subcarriers may be understood as being composed of odd numbered subcarriers, such as #1 subcarrier and #3 subcarrier; the sub-carrier with a value of modulo 4 equal to 0 may be understood as being composed of sub-carriers with a value of 0 numbered modulo 4, such as a #0 sub-carrier, a #4 sub-carrier, a #8 sub-carrier, and the like; the sub-carrier with modulo 4 value of 1 can be understood as being composed of sub-carriers with numbering modulo 4 value of 1, such as #1 sub-carrier, #5 sub-carrier, and #9 sub-carrier; the modulo-4 subcarriers with a value of 2 and the modulo-4 subcarriers with a value of 3 may be understood as being composed of the numbered modulo-4 subcarriers with a value of 2 and the numbered modulo-4 subcarriers with a value of 3, such as #2 subcarriers, #3 subcarriers, #6 subcarriers, and #7 subcarriers. The same reason is known, and the description is omitted.

Specifically, the configuration information may be M-bit information, where M is an integer. The following describes an implementation in which the M-bit information may exist.

Mode 1:

further, the M-bit information may be presented in an encoding combination manner or a bitmap (bitmap) manner. It is to be understood that the configuration information may be M-bit information, and the M-bit information may indicate that the ACK or NACK feedback uses resources in a code combining manner or a bit bitmap manner.

For example, if M is 4, the configuration information is 4 bits of information. When the 4-bit information indicates that ACK or NACK feedback uses resources by using a coding combination manner or a bit bitmap manner, 0000 represents that comb teeth are 1, 0001 represents that comb teeth are 2 and use even subcarriers, 0010 represents that comb teeth are 2 and use odd subcarriers, and the like, which are described in the above "4 bits" in the content of the "dynamic scheduling data control information" specifically, and are not described again.

Mode 2:

further, N bits of the M-bit information may be used to represent the comb type parameter, and the remaining bits of the M-bit information except the N bits may be used to represent the starting comb subcarrier group information or the comb subcarrier group information; or, the remaining bits of the M-bit information except the N bits are reserved bits. Wherein N is an integer less than M. It should be noted that, compared with "mode 1" and "mode 2", the method has the characteristics of large signaling overhead and the like.

For example, in order to implement the above "mode 1" in all cases where ACK or NACK feedback uses resources indicated by 4 bits of information, M may take the value of 5, that is, the configuration information is 5 bits of information, and the first 2 bits of the 5 bits of information are used to represent a comb type parameter, and the remaining bits are used to represent start comb subcarrier group information or comb subcarrier group information; alternatively, the remaining bits are reserved bits. Wherein the first 2 bits are "00" which represents a comb of 1; the first 2 bits are "01" which represents that the comb teeth are 2; the first 2 bits being "10" represents a comb of 4. At this time, the 5-bit information of "00 xxx" represents that the comb is 1, and "x" represents a reserved bit; the 5 bits of information of "01000" represents that the comb is 2 and even number of subcarriers are used; the 5 bits of information of "01001" represents that the comb is 2 and odd number subcarriers are used; the 5 bits of information of "01010" represents that the comb is 2 and all subcarriers are used; the 5 bits of information being "10000" represents a subcarrier with comb teeth of 4 and a value of 0 using modulo 4; the 5 bits of information "10001" represents a subcarrier with a comb 4 and a value of 1 modulo 4. The same reason for the rest can be known, and detailed description is omitted. It can be seen that, compared to 4 bits in "mode 1", 5 bits in "mode 2" have the characteristics of large signaling overhead and the like.

S320, the terminal determines whether the ACK or the NACK in the first resource pool feeds back the used resource according to the configuration information.

Wherein, the first resource pool can be used to represent a group of resources used for feeding back ACK or NACK information within a superframe composed of 48 radio frames.

It should be noted that, as can be seen from the above-mentioned contents of "frame structure and physical resources", one superframe in the embodiment of the present application may include 48 radio frames, one radio frame may include 7 or 8 CP-OFDM symbols, and one symbol may include 39 subcarriers. Therefore, the first resource pool is represented as a group of resources for feeding back ACK or NACK information within one superframe, and the minimum granularity of the first resource pool is a subcarrier.

It should be further noted that ACK or NACK feedback in the first resource pool uses resources, which can be understood as whether resources in the first resource pool used when ACK feedback information or NACK feedback information is fed back are in a continuous subcarrier manner or in a comb-shaped subcarrier manner, and which numbered subcarriers constitute the resources in the first resource pool used when ACK feedback information or NACK feedback information is fed back.

It is further noted that the first resource pool is included in each superframe.

Specifically, the resource used for ACK or NACK feedback in the first resource pool may include at least one of the following: comb tooth is 1, comb tooth is 2 and uses even number subcarriers, comb tooth is 2 and uses odd number subcarriers, comb tooth is 2 and uses all subcarriers, comb tooth is 4 and uses subcarriers with value 0 of modulo 4, comb tooth is 4 and uses subcarriers with value 1 of modulo 4, comb tooth is 4 and uses subcarriers with value 2 of modulo 4, comb tooth is 4 and uses subcarriers with value 3 of modulo 4, comb tooth is 4 and uses subcarriers with value 0 of modulo 4 and values 1 of modulo 4, comb tooth is 4 and uses subcarriers with value 2 of modulo 4 and values 3 of modulo 4, comb tooth is 4 and uses subcarriers with value 1 of modulo 4, value 1 of modulo 4 and values 2 of modulo 4.

It should be noted that, as can be seen from the above description, when the configuration information includes the comb type parameter and the starting comb subcarrier group information for ACK or NACK feedback, and the comb type parameter indicates that the comb and the starting comb subcarrier group information indicate that the comb is 2 and even subcarriers are used, the terminal determines, according to the configuration information, that the ACK or NACK feedback used resource in the first resource pool is 2 in the comb in the first resource pool and even subcarriers are used. The same reason is known, and is not described herein.

Further, the first resource pool may comprise a first ACK resource pool of the set of ACK resource pools; wherein, the ACK resource pool set may be used to indicate at least one set of resource pools used for feeding back ACK or NACK information within a superframe composed of 48 radio frames.

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

Further, the set of ACK resource pools may be configured by a communication domain system message (DomainSysInfo). Wherein the communication domain system message is transmitted by a management device in the communication domain in a broadcast manner to terminals in the communication domain.

In combination with the description of the ACK resource pool set and the content of the "T node specific control information resource pool information", when the terminal is not configured with the T node specific control information resource pool, the terminal detects control information using the communication domain common control information resource pool, and feeds back ACK information using the first ACK resource pool in the ACK resource pool set. Therefore, in order to solve the problem that the information of the ACK feedback used resources in the first ACK resource pool is not specified by the current protocol standard, the embodiment of the present application configures the ACK feedback used resources in the first ACK resource pool through the configuration information.
