AI Technical Summary
Existing wireless communication technologies face challenges in efficiently multiplexing uplink control channel signals from multiple users in shared frequency spectra due to power spectral density (PSD) requirements, which limits the number of devices that can transmit in the frequency spectrum when frequency occupancy is spread over a wider bandwidth.
Employing time-domain code-division multiplexing (CDM), frequency-domain CDM, spatial-division multiplexing (SDM), and frequency multiplexing with cyclic-shift separation to multiplex PUCCH transmissions from different UEs on the same time-frequency resources, using frequency interlaces, and assigning a fraction of frequency interlace based on PSD requirements and link parameters.
Improves PUCCH multiplexing capacity, allowing for increased spectrum utilization efficiency and power utilization, supporting up to six UEs for certain formats and up to seven UEs for others, while maintaining PSD compliance.
