[0037] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0038] The definitions or explanations of the concepts and terms involved in this application are as follows.

[0039] Grant Node (GN): The node to which the vehicle-mounted wireless short-range communication system sends data scheduling information.

[0040] Terminal Node (TN): A node in the vehicle-mounted wireless short-range communication system that receives data scheduling information and sends data according to the data scheduling information.

[0042] Super Frame (SF) is the time length of 48 wireless frames in the vehicle-mounted wireless short-range communication system.

[0043] The technical solution of the embodiment of the present application can be applied to Figure 1 The exemplary communication system 100 shown includes a first node 110 and a second node 120 , wherein the first node 110 and the second node 120 are in communication connection.

[0044] The exemplary communication system 100 may be, for example, a vehicle-mounted wireless short-range communication system.

[0045] The first node 110 in the embodiment of the present application is a management node, which may be a network device used to communicate with a terminal. The network device may be a vehicle-mounted domain controller, a smart phone, a smart wearable device, etc., but the embodiment of the present application is not limited thereto.

[0046] The second node 120 in the embodiment of the present application may refer to a user device, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent or a user device. The second node may also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a relay device, a vehicle-mounted device, a wearable device, etc., which is not limited in the embodiment of the present application.

[0047] In an embodiment of the present application, the first node 110 or the second node 120 includes a hardware layer, an operating system layer running on the hardware layer, and an application layer running on the operating system layer. The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and a memory (also referred to as main memory).

[0048] At present, the security of data transmission between the management node and the terminal node is improved by adding a mask to the last 12 bits of the check bit sequence with a 12-bit physical layer identification ID. However, because the second-category data information transmission overhead resource indication information is a public control information, and the 12-bit physical layer identification ID is a user-specific ID, under this method, other users in the network will not be able to decode the second-category data information transmission overhead resource indication information.

[0049] In view of the above problems, an embodiment of the present application proposes an information processing method, which is described in detail below with reference to the accompanying drawings.

[0050] See also Figure 2 , Figure 2 is a flowchart of an information processing method provided by an embodiment of the present application, such as Figure 2 As shown, the method includes s 201 to s 204, wherein:

[0051] s 201. A first node obtains a target data information transmission overhead resource code, where the target data information transmission overhead resource code is used to indicate an overhead resource.

[0052] The target data information transmission overhead resource code is the input information bit sequence for cyclic redundancy check operation, denoted as a 0 ,a 1 ,a 2 ,a 3,…a A-1 , where A is the number of input bits, the target data information transmission overhead resource code includes 40 bits of wireless frame time-frequency resource indication information, 1 bit of system overhead configuration period indication information, and 4 bits of system overhead symbol number information, etc. The target data information is the second type of data information, and the overhead resources can be resources other than resources for transmitting the second type of data information in the next superframe of the current superframe or at the beginning of the next superframe, that is, resources not used for transmitting the second type of data information. The second type of data information includes G link second type of data information and T link second type of data information. Among them, the second type of data information demodulation reference signal corresponding to the G link second type of data information transmission is called the G link second type of data information demodulation reference signal, which is transmitted using the resources in the G link data symbol; the second type of data information demodulation reference signal corresponding to the T link second type of data information transmission is called the T link second type of data information demodulation reference signal, which is transmitted using the resources in the T link data symbol.

[0053] s202. The first node obtains a cyclic redundancy check output sequence bit according to the target data information transmission overhead resource code.

[0054] The cyclic redundancy check output sequence bits refer to the output bits of the cyclic redundancy check operation, and the cyclic redundancy check output sequence bits are 69 bits in total, including 45 bits of the target data information transmission overhead resource code and 24 bits of check bits.

[0055] Optionally, the implementation method of the first node obtaining the cyclic redundancy check output sequence bits according to the target data information transmission overhead resource code may be: when the first node obtains the target data information transmission overhead resource code, the cyclic redundancy check output sequence bits are obtained according to the target data information transmission overhead resource code.

[0056] Optionally, the first node obtains the cyclic redundancy check output sequence bits according to the target data information transmission overhead resource code in an implementation manner that: after the first node obtains the first preset time interval of the target data information transmission overhead resource code, the first node obtains the cyclic redundancy check output sequence bits according to the target data information transmission overhead resource code. The first preset time interval may be 0.1ms, the first preset time interval may be 0.01ms, etc., and the first preset time interval is not specifically limited.

[0057] s 203. The first node obtains a target mask sequence bit.

[0058] The target mask sequence bits are used to add a mask to the cyclic redundancy check output sequence bits.

[0059] s 204. The first node obtains transmission overhead resource indication information according to the cyclic redundancy check output sequence bits and the target mask sequence bits, and sends the transmission overhead resource indication information to the second node, wherein the transmission overhead resource indication information is used to instruct the second node to obtain the target data information transmission overhead resource code according to the transmission overhead resource indication information.

[0060] Among them, the transmission overhead resource indication information refers to the second type of data information transmission overhead resource indication information, which is sent using the common resources of the control information. The transmission overhead resource indication information is a cyclic redundancy check output sequence bit with an added mask. Since it includes the target data information transmission overhead resource code, the transmission overhead resource indication information can also be used to indicate overhead resources.

[0061] There is no specific limitation on the order in which s203 and s202 occur. It is possible that s203 occurs before s202, or after s202, or at the same time.

[0062] It can be seen that in the embodiment of the present application, the first node first obtains the target data information transmission overhead resource code, and then obtains the cyclic redundancy check output sequence bits according to the target data information transmission overhead resource code, and the target data information transmission overhead resource code is used to indicate the overhead resources. In addition, the target mask sequence bits are obtained, and finally, the transmission overhead resource indication information is obtained according to the cyclic redundancy check output sequence bits and the target mask sequence bits, and the transmission overhead resource indication information is sent to the second node, and the transmission overhead resource indication information is used to indicate that the second node obtains the target data information transmission overhead resource code according to the transmission overhead resource indication information. It can be seen that the first node can perform a cyclic redundancy check on the target data information transmission overhead resource code to be verified, and obtain the cyclic redundancy check output sequence bits. By adding a mask to the cyclic redundancy check output sequence bits, the transmission overhead resource indication information that can instruct the second node to obtain the target data information transmission overhead resource code is obtained, and the users in the cell can share common control information.

[0063] In a possible embodiment, the target mask sequence bits are used to reflect one of a communication domain identity code ID, a target superframe number, and a predefined physical layer identifier, and the target superframe number includes the superframe number corresponding to the superframe where the target data information transmission overhead resource code is located.

[0064] The communication domain refers to a resource set consisting of resources on a carrier used by the first node for sending synchronization signals, broadcast information, G link control information, and resources that can be scheduled and configured by the first node.

[0065] It can be seen that in this example, the communication domain identity code ID, the target superframe number and the predefined physical layer identifier are all information that can be obtained by the second node. Therefore, the second node can obtain the target data information transmission overhead resource code based on the target mask sequence bit decoding transmission overhead resource indication information, thereby improving the reliability of sharing public control information among users in the cell.

[0066] In a possible embodiment, the first node obtains a cyclic redundancy check output sequence bit according to the target data information transmission overhead resource code, including: the first node obtains a cyclic redundancy check length; the first node determines a cyclic redundancy check generator polynomial according to the cyclic redundancy check length; the first node obtains the cyclic redundancy check output sequence bit according to the target data information transmission overhead resource code and the cyclic redundancy check generator polynomial.

[0067] Wherein, the cyclic redundancy check length L is 24, and the cyclic redundancy check generator polynomial is: g CRC24B (D)=[D 24 +D 23 +D 21 +D 20 +D 17 +D 15 +D 13 +D 12 +D 8 +D 4 +D 2 +D+1]; when using the cyclic redundancy check generator polynomial g CRC24B (D), the output bit sequence after cyclic redundancy check is expressed as b 0 ,b 1 ,b 2 ,b 3 ,……b B-1 , where B = A + L. The relationship between the input information bit, check bit, and output bit is:

[0068] b k =a k , where k = 0, 1, 2…A-1;

[0069] b k =p k-A , where k=A,A+1,A+2...A+L-1.

[0070] It can be seen that in this example, the first node can obtain the cyclic redundancy check length, and determine the cyclic redundancy check generating polynomial according to the cyclic redundancy check length, and then, according to the target data information transmission overhead resource code and the cyclic redundancy check generating polynomial, obtain the cyclic redundancy check output sequence bits, and finally obtain the transmission overhead resource indication information, thereby improving the intelligence of the first node in obtaining the transmission overhead resource indication information.

[0071] In a possible embodiment, the first node obtains transmission overhead resource indication information according to the cyclic redundancy check output sequence bits and the target mask sequence bits, and sends the transmission overhead resource indication information to the second node, including: the first node obtains first sequence bits according to the lower m bits of the cyclic redundancy check output sequence bits and the target mask sequence bits, m is a positive integer less than or equal to the number of bits of the check sequence bits, and the number of bits of the target mask sequence bits is m; the first node obtains the transmission overhead resource indication information according to the first sequence bits.

[0072] That is, m is a positive integer less than or equal to 24. In practical applications, when it is necessary to add a mask to the cyclic redundancy check output bit sequence, the output bit sequence after the cyclic redundancy check is expressed as b 0 ,b 1 ,b 2 ,b 3 ,……b B-1 , where B = A + L. The relationship between the input information bit, check bit, and output bit is:

[0073] b k =a k , where k = 0, 1, 2…A-1;

[0074] b k =p k-A , where k=A,A+1,A+2...A+11;

[0075] b k =p k-A +x PID, )mod2, where k=A+12,A+13,A+14...A+L-1;

[0076] Where L = 24, x PID, ,x PID, ,x PID, ,…,x PID, is the target mask sequence bit.

[0077] It can be seen that in this example, after the first node performs a cyclic redundancy check on the input bit sequence to obtain the cyclic redundancy check output sequence bits, it adds a mask to the cyclic redundancy check output sequence bits through the target mask sequence bits to obtain the transmission overhead resource indication information, thereby further improving the intelligence of the first node in obtaining the transmission overhead resource indication information.

[0078] In a possible embodiment, the target mask sequence bits include any one of the following: the high m bits in the communication domain ID; the low m bits in the communication domain ID; any m bits in the communication domain ID; the high m bits of the target superframe number; the low m bits of the target superframe number; any m bits of the target superframe number; the high m bits in the predefined physical layer identifier; the low m bits in the predefined physical layer identifier; any m bits in the predefined physical layer identifier.

[0079] It can be understood that the number of bits in the communication domain ID, the target superframe number and the predefined physical layer identifier is greater than or equal to m.

[0080] See also Figure 3 , Figure 3 is a flow chart of another information processing method provided by an embodiment of the present application, such as Figure 3 As shown, the method includes s 301 to s 303, wherein:

[0081] s 301. A second node receives transmission overhead resource indication information from a first node, where the transmission overhead resource indication information includes a target data information transmission overhead resource code, where the target data information transmission overhead resource code is used to indicate overhead resources.

[0082] Among them, the transmission overhead resource indication information refers to the second type of data information transmission overhead resource indication information, which is sent using the common resources of the control information. The transmission overhead resource indication information is a cyclic redundancy check output sequence bit with an added mask. Since it includes the target data information transmission overhead resource code, the transmission overhead resource indication information can also be used to indicate overhead resources.

[0083] The target data information transmission overhead resource code is the input information bit sequence for cyclic redundancy check operation, denoted as a 0 ,a 1 ,a 2 ,a 3 ,…a A-1, where A is the number of input bits, the target data information transmission overhead resource code includes 40 bits of wireless frame time-frequency resource indication information, 1 bit of system overhead configuration period indication information, and 4 bits of system overhead symbol number information, etc. The target data information is the second type of data information, and the overhead resources can be resources other than resources for transmitting the second type of data information in the next superframe of the current superframe or at the beginning of the next superframe, that is, resources not used for transmitting the second type of data information. The second type of data information includes G link second type of data information and T link second type of data information. Among them, the second type of data information demodulation reference signal corresponding to the G link second type of data information transmission is called the G link second type of data information demodulation reference signal, which is transmitted using the resources in the G link data symbol; the second type of data information demodulation reference signal corresponding to the T link second type of data information transmission is called the T link second type of data information demodulation reference signal, which is transmitted using the resources in the T link data symbol.

[0084] s 302. The second node obtains a target mask sequence bit.

[0085] Optionally, the second node may acquire the target mask sequence bits by: acquiring the target mask sequence bits when the second node receives the transmission overhead resource indication information from the first node.

[0086] Optionally, the second node obtains the target mask sequence bits in an implementation manner that: after the second node receives the transmission overhead resource indication information from the first node at a second preset time interval, the second node obtains the cyclic redundancy check output sequence bits according to the target data information transmission overhead resource code. The second preset time interval may be 0.5 ms, the second preset time interval may be 0.08 ms, etc., and the second preset time interval is not specifically limited.

[0087] s 303. The second node obtains the target data information transmission overhead resource code according to the transmission overhead resource indication information and the target mask sequence bits.

[0088] The implementation method for the second node to obtain the target data information transmission overhead resource code based on the transmission overhead resource indication information and the target mask sequence bits may be: the second node decodes the transmission overhead resource indication information according to the target mask sequence bits to obtain the target data information transmission overhead resource code.

[0089] It can be seen that in the embodiment of the present application, the second node receives transmission overhead resource indication information from the first node, the transmission overhead resource indication information includes a target data information transmission overhead resource code, and the target data information transmission overhead resource code is used to indicate overhead resources. In addition, the target mask sequence bits are obtained, and then the target data information transmission overhead resource code is obtained according to the transmission overhead resource indication information and the target mask sequence bits. It can be seen that the second node can obtain the transmission overhead resource indication information and the target mask sequence bits to obtain the target data information transmission overhead resource code, thereby realizing the sharing of public control information by users in the cell.

[0090] In a possible embodiment, the transmission overhead resource indication information is obtained by the first node performing the following operations: obtaining a target data information transmission overhead resource code; obtaining a cyclic redundancy check output sequence bit based on the target data information transmission overhead resource code; obtaining a target mask sequence bit; and obtaining the transmission overhead resource indication information based on the cyclic redundancy check output sequence bit and the target mask sequence bit.

[0091] The cyclic redundancy check output sequence bits refer to the output bits of the cyclic redundancy check operation, and the cyclic redundancy check output sequence bits are 69 bits in total, including 45 bits of the target data information transmission overhead resource code and 24 bits of check bits.

[0092] Optionally, the implementation method of the first node obtaining the cyclic redundancy check output sequence bits according to the target data information transmission overhead resource code may be: when the first node obtains the target data information transmission overhead resource code, the cyclic redundancy check output sequence bits are obtained according to the target data information transmission overhead resource code.

[0093] Optionally, the first node obtains the cyclic redundancy check output sequence bits according to the target data information transmission overhead resource code in an implementation manner that: after the first node obtains the first preset time interval of the target data information transmission overhead resource code, the first node obtains the cyclic redundancy check output sequence bits according to the target data information transmission overhead resource code. The first preset time interval may be 0.1ms, the first preset time interval may be 0.01ms, etc., and the first preset time interval is not specifically limited.

[0094] In a possible embodiment, the target mask sequence bits are used to reflect one of a communication domain identity code ID, a target superframe number, and a predefined physical layer identifier, and the target superframe number includes the superframe number corresponding to the superframe where the target data information transmission overhead resource code is located.

[0095] The communication domain refers to a resource set consisting of resources on a carrier used by the first node for sending synchronization signals, broadcast information, G link control information, and resources that can be scheduled and configured by the first node.

[0096] It can be seen that in this example, the communication domain identity code ID, the target superframe number and the predefined physical layer identifier are all information that can be obtained by the second node. Therefore, the second node can obtain the target data information transmission overhead resource code based on the target mask sequence bit decoding transmission overhead resource indication information, thereby improving the reliability of sharing public control information among users in the cell.

[0098] Wherein, the cyclic redundancy check length L is 24, and the cyclic redundancy check generator polynomial is: g CRC24B (D)=[D 24 +D 23 +D 21 +D 20 +D 17 +D 15 +D 13 +D 12 +D 8 +D 4 +D 2 +D+1]; when using the cyclic redundancy check generator polynomial g CRC24B (D), the output bit sequence after cyclic redundancy check is expressed as b 0 ,b 1 ,b 2 ,b 3 ,……b B-1 , where B = A + L. The relationship between the input information bit, check bit, and output bit is:

[0099] b k =a k , where k = 0, 1, 2…A-1;

[0100] b k =p k-A , where k=A,A+1,A+2...A+L-1.

[0101] It can be seen that in this example, the first node can obtain the cyclic redundancy check length, and determine the cyclic redundancy check generating polynomial according to the cyclic redundancy check length, and then, according to the target data information transmission overhead resource code and the cyclic redundancy check generating polynomial, obtain the cyclic redundancy check output sequence bits, and finally obtain the transmission overhead resource indication information, thereby improving the intelligence of the first node in obtaining the transmission overhead resource indication information.
