Problems solved by technology

Obviously, the BSR mechanism of the existing LTE system only needs to receive one type of BSR and does not need to distinguish between BSRs. Therefore, the BSR of the D2D link cannot be identified, so it cannot be directly used to report the BSR of the D2D link

Embodiment Construction

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] The core idea of ​​the present invention is: the base station configures a control parameter specially used for D2DBSR reporting for the UE, and the UE determines the D2DBSR sending opportunity according to the control parameter, and when sending uplink data, first judges whether the uplink data belongs to D2D service data, If so, use the D2DBSR reporting method to send the BSR to request the corresponding resource configuration. In the D2DBSR reporting, use the MAC subheader of the MACCE to notify the network side of the D2DBSR type, so that the base station can know the resource type requested by the BSR, so that it can Allocate D2D link resources for it.

Abstract

The application discloses a reporting method for a buffer status report. The reporting method comprises the steps: a base station configures in advance a control parameter of a D2D BSR to UE, the control parameter of the D2D BSR including a D2D BSR periodic timer and a D2D BSR retransmission timer; when the UE needs to send uplink data, people determine that whether the uplink data belongs to data of a D2D service, a BSR is sent to the base station and a corresponding link resource is applied according to a reporting mechanism of the D2D BSR if the uplink data belongs to data of the D2D service, and the BSR is sent to the base station and a corresponding link resource is applied according to a reporting mechanism of a cellular network if the uplink data does not belong to data of the D2D service, wherein the reporting mechanism of the D2D BSR includes the step that when the UE determines that the D2D BSR needs to be reported at present according to the control parameter of the D2D BSR, the D2D BSR is sent to the base station by means of an MAC CE; an MAC sub-head of the MAC CE carries type indication information of the D2D BSR; and the base station, according to the type indication information, knows that the BSR carried by the MAC CE is a D2D BSR, and correspondingly distributes resources according to the D2D BSR.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method for reporting a buffer status report (BSR). Background technique [0002] In the existing LTE system, the data transmission between two UEs is realized through the relay on the network side. The sending end user equipment (UE) first sends the communication data to the network side, and then the network side sends the communication data to the network side. The data is forwarded to the receiving end UE. Even if two UEs that are close to each other want to communicate, the communication data must be transmitted by the network side before being sent to the other party. The introduction of device-to-device (D2D) technology is aimed at the application scenario where the distance between the UE at the sending end and the UE at the receiving end is relatively close. At this time, the communication data can be directly transmitted between the two UEs, without the need for rela...
