Method, device and apparatus for determining beam of forwarding link for backhaul, and storage medium

A method for determining beam for backhaul link, performed by a network device, comprising:

• determining first beam information, wherein the first beam information comprises beam information corresponding to a control link between a network control repeater and the network device, or unified transmission configuration indicator (TCI) corresponding to a network control repeater;
• and
• determining a beam for a backhaul link between the network control repeater based on the first beam information;
• or
• determining second beam information, wherein the second beam information is default configured beam information for a backhaul link, or beam information for a backhaul link indicated by the network device to the network control repeater, or beam information for a backhaul link determined based on a predefined rule;
• and
• determining a beam for the backhaul link based on the second beam information.

A network control repeater, comprising a memory, a transceiver and a processor,

• where the memory is used for storing a computer program, the transceiver is used for receiving and sending data under control of the processor, and the processor is used for reading the computer program in the memory and performing the following operations:
• obtaining first beam information, wherein the first beam information comprises beam information for a control link or unified transmission configuration indicator (TCI);
• and
• determining a beam for a backhaul link based on the first beam information;
• or
• obtaining second beam information, wherein the second beam information is default configured beam information for a backhaul link, or beam information for a backhaul link indicated by a network device, or beam information for a backhaul link determined based on a predefined rule;
• and
• determining a beam for the backhaul link based on the second beam information.
