Embodiment Construction

[0056] As mentioned in the background technology section, when using uplink scheduling to allocate D2D link resources, some terminals in the D2D link report BSR to the AP, while other terminals fail to report the BSR, and the AP needs to know the D2D All terminals in the link can allocate resources for the D2D link to the terminals in the D2D link only by using the cache status parameters for the D2D link. Therefore, a certain terminal in the D2D link fails to actively When reporting the BSR, the AP will not be able to allocate D2D link resources to the terminals that successfully report the BSR in the D2D link, which will affect the progress of the D2D service.

[0057] To solve this problem, the embodiment of the present invention proposes a method for allocating resources. After receiving the first BSR reported by the first terminal, the AP determines the first D2D link according to the identifier of the first D2D link contained in the first BSR except Including not only th...

Abstract

Disclosed are a method, apparatus and device for allocating a resource, which are used for solving the problem that an AP cannot allocate a D2D link resource to a terminal successfully sending a BSR in a D2D link because there is a terminal unsuccessfully sending the BSR to the AP in the D2D link. The method comprises: an AP receiving a first BSR reported by a first terminal; according to a stored D2D link information table and an identification of a first D2D link contained in the first BSR, determining that the first D2D link comprises a second terminal; sending a BSR request and an uplink resource grant to the second terminal; receiving a second BSR returned by the second terminal; and according to a buffer status parameter of the first terminal contained in the first BSR and a buffer status parameter of the second terminal contained in the second BSR, allocating a resource for the first D2D link to the first terminal and the second terminal.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and equipment for allocating resources. Background technique [0002] Device-to-device (English: Device-to-Device; abbreviation: D2D) communication is a kind of business data that is not forwarded by the access point (English: Access Point; abbreviation: AP) and the core network, and is directly transmitted by the source terminal device through the air interface. A new technology for target terminal equipment, which can improve the spectral efficiency of wireless communication systems, alleviate the problem of lack of spectrum resources, and reduce the transmission power of terminal equipment. [0003] In D2D communication, D2D link resources can be allocated to terminals through uplink scheduling. For example, for the first terminal and the second terminal that have established a D2D link, refer to figure 1 , when the two have D2D transmission r...
