A direct communication link resource allocation method and terminal

Abstract

The invention provides a direct communication link resource allocation method and a terminal, which relate to the technical field of communication. The direct communication link resource allocation method is applied to a terminal, and includes: obtaining a mapping relationship between a specific target of the direct communication link and a logical channel priority LCP restriction parameter of the direct communication link; performing direct communication according to the mapping relationship Resource allocation of communication links; wherein, the specific target includes: QoS parameters or logical channels. In the above solution, by obtaining the mapping relationship between the specific target of the direct communication link and the logical channel priority LCP limit parameter of the direct communication link, according to the mapping relationship, the resource allocation of the direct communication link is performed, thereby improving the The network communication process ensures that the direct communication link in the 5G system can perform normal data transmission.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a direct communication link resource allocation method and a terminal. Background technique [0002] The LCP (Logical Channel Prioritization, logical channel priority) of the Uu interface of the LTE (Long Term Evolution, long term evolution) system is performed based on the priority parameter priority corresponding to a single RB (Radio Bearer, radio bearer) configured in the network setting. [0003] Allows direct communication between devices and devices that are in close proximity to each other. For ease of description, a link defining direct communication between terminals is called a Sidelink (translated as a direct communication link or bypass), and the corresponding air interface is also called a direct communication interface. Such as figure 1 shown. [0004] The devices in direct communication can all be on-net, or all off-net, or some devices can be ...
