Embodiment 1

[0072] An embodiment of the present invention provides a resource configuration method. figure 2 It is a schematic flowchart of a resource allocation method in Embodiment 1 of the present invention; figure 2 As shown, the resource allocation method includes:

[0073] Step 201: The network side device allocates uplink resources for low-latency services through configuration or reservation.

[0074] In this embodiment, the network side equipment includes at least one of the following equipment: evolved base station (eNB), relay station (RN), cell coordination entity (MCE), gateway (GW), mobility management equipment (MME) , an Evolved Universal Terrestrial Radio Access Network (EUTRAN) Operations Administration and Maintenance (OAM) manager, etc., in each embodiment of the present invention, an eNB is used as a network side device as an example for illustration.

[0075] Here, the network-side device allocates the uplink resources of the low-latency service through configura...

Embodiment 2

[0090] The embodiment of the present invention also provides a resource configuration method. Figure 4 It is a schematic flowchart of a resource allocation method in Embodiment 2 of the present invention; Figure 4 As shown, the method includes:

[0091] Step 301: After receiving the trigger indication of the low-latency service, the terminal searches for and obtains uplink scheduling information.

[0092] Here, the searching and obtaining the uplink scheduling information includes: searching the common search space of the PDCCH, or the specific search space of the terminal, or the dedicated search space of the low-delay service to obtain the uplink scheduling information.

[0093] The dedicated search space for the low-delay service may be specific positions on a specific symbol.

[0094] Wherein, before obtaining the uplink scheduling information, the method further includes: the terminal obtains a preset identifier through a broadcast message; or obtains a preset identif...

Embodiment 3

[0103] The embodiment of the present invention also provides a resource configuration method. In this embodiment, the V2X terminal transmits information based on the uplink resources pre-configured by the base station and based on the Uu link (that is, the link from the Vehicle to the eNodeB).

[0104] In a nutshell, first of all. The base station sends pre-configured related information, and the pre-configured related information can be carried by the PDCCH, where the format of the PDCCH can be format0, format4, or a newly added format formatX, and for the PDCCH carrying specific information, it adopts a predefined V-RNTI is scrambled, and V-RNTI notifies V2X terminals within the coverage area through broadcast messages; or it can be sent to V2X terminals through RRC signaling when the base station establishes a V2X link with V2X terminals; or it can be pre-configured in a predefined way. Then the V2X terminal receives the preconfigured related information. The preconfigure...

Abstract

The embodiment of the invention discloses a resource allocation method, network side equipment and a terminal. The method comprises the following steps: enabling the network side equipment to allocate uplink resources of a low-latency service through a configuration or reservation mode; and generating uplink scheduling information based on the allocated uplink resources, and sending the uplink scheduling information.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a resource configuration method, network side equipment and terminal. Background technique [0002] Vehicle-to-external (V2X, Vehicle-to-X) includes vehicle-to-vehicle (V2V, Vehicle-to-Vehicle), vehicle-to-equipment (V2I / N, Vehicle-to-Infrastructure / Network) and vehicle-to-person (V2P, Vehicle-to-Vehicle -to-Pedestrian). The difference between V2X communication and the device-to-device (D2D, Device-to-Device) communication in Release 12 (R12, Release 12) lies in the characteristics of increased mobile speed, increased user density, high reliability requirements, and real-time response. Conventional D2D communication does not need to consider the above-mentioned high requirements. Therefore, the existing mechanism of D2D communication cannot meet the needs of V2X communication, and must be optimized according to the characteristics of V2X. [0003] For V2X based on Uu...
