example 1

[0084] The type indication information is indicated by an independent indication field in the first-level SCI. The length of the indication field can be 1 bit, and the corresponding two code points are 0 and 1 respectively. The code point 0 corresponds to that the information is not used to trigger assistance. Trigger information for information transmission, code point 1 corresponds to this information is trigger information for triggering auxiliary information transmission.

[0085] Similarly, the type indication information is indicated by an independent indication field in the second-level SCI. The length of the indication field can be 1 bit, and the corresponding two code points are 0 and 1 respectively. Code point 0 corresponds to the information not used For the trigger information that triggers the transmission of the auxiliary information, the code point 1 corresponds to the information that is the trigger information for triggering the transmission of the auxiliary in...

example 2

[0089] In the second-level SCI, the code point reserved by the existing indication field is used to indicate the type indication information, and the first information receiving end judges whether the first information is used to trigger auxiliary information transmission according to the decoding situation of the indication field in the second-level SCI trigger information. For example, the communication range indication field in the second-level SCI indicates the reserved code point. The length of the communicationrange indication field is 5 bits, and there are several reserved code points. For example, the reserved code point 11111 is used to indicate that the first information carried in the second-level SCI is trigger information for triggering auxiliary information transmission.

[0090] In addition, the available indication field also includes a HARQ process ID indication field, an NDI indication field, an RV indication field, a sourceID indication field, a destination ...

example 3

[0149] The time information used for auxiliary information transmission can be obtained by associating / mapping the data Qos parameters to be transmitted by the first device, and the corresponding QoS parameters can be delay information, priority information, reliability information, data rate, etc. of the data to be transmitted . When indicating the position of the time window within a period of time L in the future, and correlating / mapping with the delay of data transmission in the QoS parameter, for example, assuming that the starting point of the transmission time window for auxiliary information is t, and the length is L, the time delay required to transmit data is T1, then:

[0150] 1.t is equal to T1;

[0151] 2.t is equal to n*T1, where n is a number between 0-1;

[0152] 3. t is equal to T1-T2, where T2

[0153] 4. When t is equal to 0, it means that the current moment will start and the future will b...

Abstract

The invention discloses an information transmission method, a device and electronic equipment . The information transmission method comprises the steps of sending first information to at least one second device, wherein the first information is used for triggering the second equipment to carry out auxiliary information transmission or is used for the second equipment to carry out resource selection or reservation. According to the embodiment of the invention, the first device sends the first information to the at least one second device, and the first information indicates the second device to carry out auxiliary information transmission or indicates the second device to carry out resource selection or reservation of data transmission, so that the transmission reliability can be improved, and the demodulation complexity can be reduced.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to an information transmission method, device and electronic equipment. Background technique [0002] The Long Term Evolution (LTE) system supports sidelink (sidelink, or translated as secondary link, side link, side link, etc.) transmission, that is, between terminals (User Equipment, UE) directly on the physical layer for data transfer. LTE sidelink communicates based on broadcasting. Although it can be used to support basic security communication of vehicle to everything (V2X), it is not suitable for other more advanced V2X services. The 5G NR (New Radio) system will support more advanced sidelink transmission designs, such as unicast, multicast or multicast, etc., so as to support more comprehensive types of services. [0003] NR V2X defines two resource allocation modes, one is mode 1, which schedules resources for the base station; the other is mo...
