Method for configuring epdcch resources in base station
A recently granted patent (Publication Number: US11924852B2) discloses a method involving a base station configuring physical resource blocks for enhanced physical downlink control channel resources and mapping them across resource elements. The method allows for the transmission of downlink control information using multiple physical resource blocks, even if a single block is sufficient, and enables the inclusion of multiple enhanced physical downlink control channels within a single physical resource block.
Furthermore, the patent describes a method for user equipment to receive transmissions from the base station, extract enhanced physical downlink control channel information, and combine it from multiple physical resource blocks. The user equipment can monitor both localized and distributed enhanced physical downlink control channel information and is configured to exclude resource elements used for other signals. This innovative method aims to optimize the transmission and reception of downlink control information in wireless communication systems.
