Direct communication resource allocation method and apparatus

A method for allocating sidelink resource, comprising:

• receiving auxiliary information reported by a sidelink user equipment;
• transmitting configuration information of logical channel groups of a sidelink interface to the sidelink user equipment to indicate that logical channels using different wireless access technologies correspond respectively to different logical channel groups;
• receiving a Buffer Status Report, BSR, reported by the sidelink user equipment based on the configuration information of logical channel groups of the sidelink interface;
• allocating transmission resources of the sidelink interface to the sidelink user equipment on physical resources corresponding to a determined wireless access technology according to a correspondence between logical channel groups and wireless access technologies;
• wherein the configuration information of logical channel groups of the sidelink interface is a mapping relationship between Quality of Service, QoS, parameters of the sidelink interface and logical channel group identifiers or a mapping relationship between logical channels of the sidelink interface and logical channel group identifiers, and logical channels in a same logical channel group only correspond to a kind of wireless access technology;
• when the configuration information of logical channel groups of the sidelink interface is the mapping relationship between logical channels of the sidelink interface and logical channel group identifiers, the auxiliary information comprises QoS parameters corresponding to each logical channel of a sidelink interface of a sidelink user equipment and a wireless access technology that each logical channel of the sidelink interface of the sidelink user equipment expects to use.

A sidelink user equipment, comprising a processor and a memory,

• wherein the processor is configured to read a program in the memory and perform the process of:
• reporting auxiliary information to a resource allocation management node;
• receiving configuration information of logical channel groups of a sidelink interface transmitted by the resource allocation management node, wherein the configuration information of logical channel groups of the sidelink interface is used to indicate that logical channels using different wireless access technologies correspond respectively to different logical channel groups;
• determining a logical channel group corresponding to a logical channel of the sidelink interface according to the configuration information of logical channel groups of the sidelink interface;
• wherein the configuration information of logical channel groups of the sidelink interface is a mapping relationship between Quality of Service, QoS, parameters of the sidelink interface and logical channel group identifiers or a mapping relationship between logical channels of the sidelink interface and logical channel group identifiers, and logical channels in a same logical channel group only correspond to a kind of wireless access technology;
• when the configuration information of logical channel groups of the sidelink interface is the mapping relationship between logical channels of the sidelink interface and logical channel group identifiers, the auxiliary information comprises QoS parameters corresponding to each logical channel of a sidelink interface of a sidelink user equipment and a wireless access technology that each logical channel of the sidelink interface of the sidelink user equipment expects to use.
