Example Embodiment

[0038] Example 1

[0039] like Figure 1a As shown, it is a schematic flowchart of a network-side V2X resource configuration method provided in Embodiment 1 of the present invention, which may include the following steps:

[0040] S11. Send configuration signaling to the user equipment UE, where the configuration signaling includes first resource pool configuration information for indicating the first resource pool and second resource pool configuration information for indicating the second resource pool.

[0041]Preferably, before step S11 is performed, the network side also needs to pre-determine at least one first resource pool and at least one second resource pool.

[0042] During specific implementation, the transmission resources in the first resource pool are used for vehicle-to-everything V2X direct communication in the first transmission mode, and the transmission resources in the second resource pool are used for the second transmission mode or for the first transmis...

Example Embodiment

[0052] In specific implementation, in the resource allocation mode scheduled by the base station, when the network side obtains the UE resource scheduling information, the following two implementations can be adopted:

[0053] Mode 1: Receive a V2X direct communication request sent by the UE

[0054] Specifically, the V2X direct communication request carries the resource scheduling information.

[0055] Mode 2: Receive the resource scheduling information reported by the UE triggered by the network side

[0056] The network side triggers the UE to report the resource scheduling information according to at least one of the following information: geographic location information of the UE, moving speed, and a vehicle type of a vehicle carrying the UE. Specifically, the UE may use real-time reporting, periodic reporting, or reporting the UE's geographic location information, the current moving speed, and the vehicle type of the vehicle carrying the UE, etc. under a specific trigge...

Example Embodiment

[0118] Embodiment 2

[0119] In order to further understand the present invention, on the basis of Embodiment 1 of the present invention, transmission resources are allocated to the UE in a semi-persistent scheduling manner, so that the UE performs V2X direct communication according to the allocated transmission resources.

[0120] During specific implementation, the configuration signaling further includes configuration information of a semi-persistent scheduling process configured for the UE, and the configuration information includes at least one of the following information: a period of semi-persistent scheduling, power control information, modulation and coding scheme MCS , Transport block size TBS.

[0121] After configuring the configuration information of the semi-persistent scheduling process for the UE, the network side can allocate the transmission resources on the first resource pool to the UE according to the period of the semi-persistent scheduling, so that the U...

Abstract

The invention discloses a vehicle-to-everything (V2X) resource allocation method, device and related equipment. The method comprises a step of sending an allocation signaling to user equipment (UE), wherein the allocation signaling comprises first resource pool allocation information used for indicating a first resource pool and second resource pool allocation information used for indicating a second resource pool, transmission resources in the first resource pool are used for V2X direction communication in a first transmission mode, and transmission resources in the second resource pool are used for V2X direct communication in a second transmission mode or used for V2X direct communication in the first transmission mode and the second transmission mode. By adopting the method provided bythe invention, when a resource allocation mode scheduled by a base station and a resource allocation mode without scheduling by virtue of the base station exist at the same time, resource allocation on the UE is realized, and the resource allocation in two resource allocation modes is coordinated.

Description

technical field [0001] The present invention relates to the field of wireless communication technologies, and in particular to a V2X resource configuration method, device and related equipment. Background technique [0002] In the Long Term Evolution (LTE, Long Term Evolution) system, a side link (sidelink) is defined to support direct communication between user equipment (User Equipment, UE). The V2X (Vehicle to Everything, Vehicle-to-everything) communication (hereinafter referred to as: PC5-based LTE-V2X), can realize vehicle-to-vehicle (V2V, Vehicle to Vehicle), vehicle-to-road (V2I, Vehicle to Infrastructure) and vehicle-to-person (V2P, Vehicle to Pedestrian) direct communication between. [0003] The PC5-based LTE-V2X will adopt the resource allocation mode (mode 1) scheduled by the base station and the resource allocation mode (mode 2) independently selected by the UE. These two resource allocation modes exist independently. [0004] For example, if the mode 1 reso...
