Problems solved by technology

[0005] Obviously, since the existing V2X communication mechanism cannot support the confidentiality within the group and the directional transmission of physical signals, it cannot meet the needs of the internal communication of the automatic fleet.
However, there is no mature technical solution to solve this technical problem

[0050] This embodiment is aimed at the CUE. In this embodiment, the CUE can determine the carrier, resource pool configuration, and sending resource and receiving resource for intra-group communication through the above-mentioned first, second, third and fourth resource determination methods. CUE receiving resources should include sending resources of all other MUEs in the fleet, so the number of receiving resources should not be less than the number of MUEs in the current fleet. In a preferred implementation, if the current number of UEs in the automatic fleet is U, and the value of U is less than the maximum number of UEs that the fleet can support, the number of receiving resources of the CUE should be equal to U+1, or when receiving The number of receiving resources is increased to U+1 after the request of UEs outside the fleet to join the fleet, and one additional receiving resource is used for new MUEs that may join the fleet. In addition, the time interval between two a...

[0054] This embodiment is aimed at the MUE, and corresponds to the implementation manner of the CUE in the first embodiment. In this embodiment, the MUE determines the locations of the sending resource and the receiving resource by receiving signaling from the CUE. The MUE may directly receive the signaling of the CUE from the transmission resources of the CUE, or receive the signaling of the CUE forwarded by other MUEs on the transmission resources of other MUEs. The MUE takes the P time slots belonging to the resource pool after the time slot where the CUE sends resources as a sending cycle, and all receiving resources and sending resources are repeated in this sending cycle until the MUE receives a new CUE signaling instruction, where P For a specific value, the MUE can determine the value of P by receiving the signaling of the CUE or the signaling of the NB when joining the automatic fleet, or determine the value of P according to the standard definition or pre-configurati...

[0061] This embodiment is aimed at CUE and MUE.

[0062] For any UE in the automatic fleet, according to an implementation of this embodiment, for the time slot with index n in the resource pool used for intra-group communication, if n mod M=i, then the automatic fleet is included in the time slot n The transmission resource of the UE whose inner index is i, where M represents the number of UEs in the current automatic fleet; in this way, the M timeslots belonging to the resource pool after (including m) the timeslot with the index m in the resource pool are defined is a sending period, where m is any value satisfying m mod M=0 within the range of resource pool time slot index values.

[0063] For any UE in the automatic fleet, according to another implementation of this embodiment, for the time slot with index n in the resource pool used for intra-group communication, if n mod 2=0, then the time slot n contains automatic The transmission resource of the UE with an even index...

Abstract

The present invention relates to a bypass communication method executed by control user equipment (CUE). The method comprises the steps of: determining a sending resource and a receiving resource usedfor intra-group communication; sending corresponding data to member user equipment (MUE) on the determined sending resource; and receiving data from the MUE on the determined receiving resource. Through the communication method, the security and the directionality of the intra-group communication can be ensured to effectively support the intra-group communication demands and improve the resourceutilization efficiency.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular, the present application relates to a bypass communication method and device. Background technique [0002] In the 3GPP standard, the direct communication link between the user equipment UE and the user equipment UE is called sidelink (Sidelink), similar to the uplink and downlink, there are control channels and data channels on the sidelink, the former is called Sidelink A bypass control channel (Physical Sidelink Control CHannel, PSCCH for short), and the latter is called a bypass data channel (Physical Sidelink Shared CHannel, PSSCH for short). The PSCCH is used to indicate the location of time-frequency domain resources (hereinafter referred to as resources) used for PSSCH transmission, the modulation and coding scheme, and the priority of data carried in the PSSCH, etc., and the PSSCH is used to carry data. [0003] Control information and data in ve...
