UE CAPABILITY REPORTING - A simplified explanation of the abstract
This abstract first appeared for US patent application 17920374 titled 'UE CAPABILITY REPORTING
The abstract describes a method for a User Equipment (UE) to report UE capability related to port selection codebooks to a Base Station (BS) under certain conditions.
- The UE reports the port selection codebooks to the BS if the active Bandwidth Part (BWP) has less than a threshold number of Physical Resource Blocks (PRBs).
- The UE does not report the port selection codebooks if it is not expected to do so by the BS.
- The UE may also report the port selection codebooks if the active BWP has less than the threshold number of PRBs and the UE is configured with the codebooks by the BS.
- The method involves predefined values for parameters such as the number of selected frequency basis, percentage of selected ports, percentage of reported non-zero coefficients, and number of precoding matrix indicator (PMI) sub-bands per channel quality information (CQI) sub-band.
Potential Applications: - 5G and beyond wireless communication systems - Mobile networks - Internet of Things (IoT) devices
Problems Solved: - Efficient reporting of UE capabilities to the BS - Optimization of resource allocation in wireless networks
Benefits: - Improved network performance - Enhanced user experience - Better utilization of resources
Commercial Applications: The technology can be used in telecommunications companies to enhance network efficiency and user experience, leading to increased customer satisfaction and retention.
Questions about the technology: 1. How does this method improve resource allocation in wireless networks? 2. What are the key parameters that determine when the UE reports the port selection codebooks to the BS?
Original Abstract Submitted
Provided is a method for a user equipment (UE). The UE performs at least one of: reporting, to a base station (BS), a UE capability related to port selection codebooks, in accordance with a determination that an active bandwidth part (BWP) has less than a threshold number of physical resource blocks (PRBs), operating according to a rule that the UE is not expected to report, to the BS, the port selection codebooks, or in accordance with a determination that the active BWP has less than the threshold number of PRBs and that the UE is configured with the port selection codebooks by the BS, assuming that a subset of parameters has a predefined value, wherein the parameters comprise a number, M, of selected frequency basis, a percentage, α, of number of selected ports, a percentage, β, of number of reported non-zero coefficients, and a number, R, of precoding matrix indicator (PMI) sub-bands per channel quality information (CQI) sub-band.
