Information processing method and apparatus, terminal device, and network device

An information processing method applied to a network device, the method comprising:

• receiving indication information sent by a terminal device;
• determining a target transmission resource type according to the indication information;
• wherein the indication information is used to indicate relationship between a sidelink destination identity and a sidelink SL transmission type, or relationship between service type information and an SL transmission type;
• the SL transmission type is SL discovery or SL communication;
• and the target transmission resource type is an SL transmission resource type corresponding to the sidelink destination identity, or an SL transmission resource type corresponding to the service type information,
• the indication information comprises second identification information of the SL transmission type;
• in a case that the second identification information appears, the indication information indicates that the SL transmission type is the SL discovery;
• the second identification information comprises a sidelink destination identity, and the sidelink destination identity corresponds to a sidelink destination index;
• in a case that the second identification information does not appear, the indication information indicates that the SL transmission type is the SL communication.

A terminal device, comprising:

• a memory, a transceiver, and a processor, wherein the memory is used to store a computer program;
• the transceiver is used to send and receive data under control of the processor;
• and the processor is used to read the computer program in the memory and perform following operations:
• sending indication information to a network device by using the transceiver, wherein the indication information is used to indicate relationship between a sidelink destination identity and a sidelink SL transmission type, or relationship between service type information and an SL transmission type, and the SL transmission type is SL discovery or SL communication,
• the indication information comprises second identification information of the SL transmission type;
• in a case that the second identification information appears, the indication information indicates that the SL transmission type is the SL discovery;
• the second identification information comprises a sidelink destination identity, and the sidelink destination identity corresponds to a sidelink destination index;
• in a case that the second identification information does not appear, the indication information indicates that the SL transmission type is the SL communication.
