Problems solved by technology

[0006] During the research and practice of related technologies, the inventor found the following problems: when the CBR cannot be measured or the CBR measurement load is reduced, the UE may not be able to determine the required radio resource parameters, and the UE cannot determine the radio resource parameters. Directly lead to the failure of normal transmission of V2X business data

Embodiment 1

[0194] In this embodiment, the UE can directly obtain the CBR. Such as Figure 10 As shown, the implementation process of wireless resource configuration in this embodiment may include:

[0195] Step 1001: The UE measures the CBR value and reports it to the eNB.

[0196] The measurement CBR can be implemented according to the configuration of the eNB, and the configuration of the eNB includes: measurement target, measurement configuration, etc.; wherein, the measurement target can include one of the following: V2X transmission resource pool, V2X carrier frequency; the measurement configuration It may include: a threshold value, that is, an S-RSSI value.

[0197] Wherein, the reporting may use RRC signaling.

[0198] In practical applications, the eNB selects the UE that needs to report the measurement, and sends measurement indication information to the UE. The measurement indication information can be sent to the UE through a system message or RRC dedicated signaling (such...

Embodiment 2

[0209] In this embodiment, the UE can directly obtain all radio resource parameters. Such as Figure 11 As shown, the implementation process of wireless resource configuration in this embodiment may include:

[0210] Step 1101: UE measures CBR and reports to eNB.

[0211] This step is similar to step 1001 and will not be repeated here.

[0212] Step 1102 : the eNB judges whether to use the system message to send radio resource parameters, if yes, go to step 1103 , otherwise go to step 1104 .

[0213] This step is similar to step 1002 and will not be repeated here.

[0214] Step 1103: The UE obtains the wireless resource parameters of the resource pool sent by the PC5 interface through the system message, and jumps to step 1105;

[0215] Step 1104: UE acquires the radio resource parameters of the PC5 interface transmission resource pool through dedicated RRC signaling;

[0216] Step 1105, the UE sends V2X service data on the PC5 interface by using the radio resource parame...

Embodiment 3

[0218] In this embodiment, the UE may acquire some radio resource parameters. Please refer to Figure 12 , the implementation process of wireless resource configuration in this embodiment may include:

[0219] Step 1201: UE measures and reports CBR.

[0220] Step 1202: The eNB chooses whether to send part of the radio resource parameters through a system message, if yes, go to step 1203, otherwise, go to step 1204.

[0221] The partial wireless resource parameters refer to all the wireless resource parameters not including the aforementioned ones, such as the maximum transmission power, the number of data block retransmissions, the number of data resource blocks, MCS, and one or more of channel occupancy rate restrictions, but not all of them. parameter.

[0222] Step 1203: The UE receives the part of radio resource parameters through a system message, and jumps to step 1205;

[0223] Step 1204, the UE signals the part of radio resource parameters through dedicated RRC sig...

Abstract

The invention discloses a method for configuring a radio resource. The method may comprise the following steps: acquiring channel busy ratio congestion control related information; determining that aPC5 interface sends a radio resource parameter of a resource pool according to the congestion control related information; and sending internet of vehicles service data on the PC5 interface accordingto the radio resource parameter. According to the method and the device in the invention, UE can select the radio resource parameter of the PC5 interface when not possessing the CBR measurement capability, unable to measure the CBR, or reducing the CBR measuring load, thereby ensuring the V2X service of the UE on the rails and realizing congestion control of the resource of the PC5 interface.

Description
