Uplink control channel resource allocation for enhanced downlink control channel
A recently granted patent (Publication Number: US12016025B2) discloses a method and apparatus for optimizing the allocation of physical uplink control channel (PUCCH) resources in wireless communication systems. The method involves transmitting a downlink control channel carrying a PUCCH resource indicator to a user equipment (UE), mapping the indicator to specific offsets, determining indices associated with demodulation reference signal (DMRS) antenna ports, and allocating PUCCH resources based on calculated offsets. The apparatus includes a processor and computer-readable storage medium executing instructions to perform the method, ensuring efficient PUCCH resource allocation for improved communication reliability.
Furthermore, the patent details additional operations such as transmitting multiple physical downlink shared channels (PDSCHs) to the UE, adjusting offsets based on transmission modes, and enabling simultaneous PUCCH transmission on multiple allocated resources using different antenna ports. The disclosed technology aims to enhance the overall performance of wireless communication systems by optimizing resource allocation and improving signal transmission efficiency. This innovation underscores the ongoing efforts in the telecommunications industry to develop advanced solutions for managing and optimizing wireless network resources effectively.
