Compal Electronics has filed a patent for a bandwidth allocation method. The method involves selecting a reference bandwidth part from a plurality of options provided by a base station, transmitting a reference signal through the reference bandwidth part, and receiving a channel report from the user equipment based on the channel status of the reference bandwidth part. If the channel quality indication in the report is not satisfactory, the user equipment is instructed to switch to a bandwidth part with a smaller frequency band. The process is repeated until a satisfactory channel quality is achieved. GlobalData’s report on Compal Electronics gives a 360-degree view of the company including its patenting strategy.

Bandwidth allocation method for user equipment in a service area
A recently filed patent (Publication Number: US20230300802A1) describes a bandwidth allocation method and system for wireless communication networks. The method involves a base station providing multiple bandwidth parts to user equipment within a service area. The base station selects a reference bandwidth part and transmits a reference signal to the user equipment through this bandwidth part. The user equipment receives the reference signal and outputs a channel report to the base station, which includes a channel quality indication.
If the channel quality indication is below a certain threshold (first critical value), the user equipment is instructed to switch to a bandwidth part with a smaller frequency band as the new reference bandwidth part. The process of transmitting the reference signal and receiving the channel report is repeated.
The channel report may also include a reference symbol received power. If the channel quality indication is above the first critical value but the reference symbol received power is below a second critical value, the process of transmitting the reference signal and receiving the channel report is repeated as well.
The patent also describes a timer in the base station that can be activated when the channel quality indication and reference symbol received power meet certain criteria. If the timer is activated and reaches a preset time, the user equipment is instructed to switch to a bandwidth part with a greater frequency band as the new reference bandwidth part.
The base station provides multiple bandwidth parts formed by resource blocks, with each resource block having a corresponding frequency band. The resource blocks are ordered in descending order according to the size of the frequency band.
The patent also includes a bandwidth allocation system that consists of a base station and user equipment. The base station provides multiple bandwidth parts to the user equipment and selects a reference bandwidth part. The user equipment receives the reference signal and outputs a channel report. The base station can instruct the user equipment to switch to a bandwidth part with a smaller frequency band as the new reference bandwidth part based on the channel quality indication.
Overall, this patent presents a method and system for efficient bandwidth allocation in wireless communication networks, allowing for dynamic adjustments based on channel conditions and resource availability.
