## Abstract

An electronic device, which comprises a memory, a processor, and a serial number length adjustment program stored in the memory and operable on the processor is disclosed. The serial number length adjustment program is executed by the processor to implement following functions: performing an angle estimation algorithm on all user equipments (UEs) through a low-frequency band to estimate beam angles of the UEs relative to the electronic device; generating high-frequency band beams of the UEs relative to the electronic device according to the estimated beam angles; and enabling the electronic device to communicate with the UEs according to the generated high-frequency band beams.

## Claims

### Claim 1

An electronic device, which comprises a memory, a processor, and a serial number length adjustment program stored in the memory and operable on the processor, wherein the serial number length adjustment program is executed by the processor to implement following steps:
performing an angle estimation algorithm on all user equipments (UEs) through a low-frequency band to estimate beam angles of the UEs relative to the electronic device;
generating high-frequency band beams of the UEs relative to the electronic device according to the estimated beam angles; and
enabling the electronic device to communicate with the UEs according to the generated high-frequency band beams.

### Claim 2 (depends on 1)

The electronic device of claim 1, wherein the processor further implements the following steps:
enabling a base station to perform a data transmission with the UEs;
determining, when a first UE of the UEs moves, whether a beam tracking is performed on the first UE;
re-generating, if the beam tracking is performed on the first UE, high-frequency band beams of the first UE relative to the electronic device; and
enabling the electronic device to communicate with the first UE according to the re-generated high-frequency band beams.

### Claim 3 (depends on 1)

The electronic device of claim 1, wherein:
each packet, transmitted from a UE to the electronic device, comprises a user-defined field storing a parameter, Active_BeamTracking; and
when the Active_BeamTracking=1, the processor further implements a function of performing a beam tracking on the UE.
