Backhaul transmission method for wireless communication, controller, base station, and gateway

A first base station, comprising:

• a backhaul transceiver of the first base station;
• a memory, configured to store an instruction;
• and
• a processor, connected to both the memory and the backhaul transceiver of the first base station, and configured to execute the instruction, to perform the following operations when executing the instruction:
• instructing the backhaul transceiver of the first base station to send information about a backhaul requirement of the first base station to a controller;
• obtaining information about a codebook from the controller by using the backhaul transceiver of the first base station, wherein the information about the codebook is determined based on the backhaul requirement of the first base station;
• and
• performing backhaul transmission with a gateway by using the backhaul transceiver of the first base station and the codebook.

A controller, comprising:

• a transceiver;
• a memory, configured to store an instruction;
• and
• a processor, connected to both the memory and the transceiver, and configured to execute the instruction, to perform the following operations when executing the instruction:
• obtaining information about a backhaul requirement of a first base station by using the transceiver;
• and
• instruct the transceiver to send information about a codebook to the first base station and a gateway to which the first base station belongs, wherein
• the information about the codebook is determined by the processor based on the backhaul requirement, and the backhaul transmission is transmission between the first base station and the gateway.

A gateway, comprising:

• a backhaul transceiver of the gateway;
• a memory, configured to store an instruction;
• and
• a processor, connected to both the memory and the backhaul transceiver, and configured to execute the instruction stored in the memory, to perform the following operations when executing the instruction:
• obtaining information about a codebook from a controller by using the backhaul transceiver of the gateway, wherein the information about the codebook is determined based on a backhaul requirement of a first base station;
• and
• performing backhaul transmission with the first base station by using the backhaul transceiver of the gateway and the codebook.
