Systems and methods for uplink feedback for high-speed downlink packet access (HSDPA)

摘要

Systems and method for uplink feedback for multipoint transmission of high-speed downlink packet access (MP-HSDPA) that may improve downlink transmission efficiency and cell coverage. For example, Channel Quality Indicator (CQI) and/or Precoding Control Indicator (PCI) that may be calculated to accommodate the needs of coordinated dynamic network scheduling. Additionally, various frame structures may be generated for the uplink feedback that may carry multiple CQI and HARQ-ACK feedbacks from MP-HSDPA. The frame structures may also address asynchronous downlink transmissions between two cells. Moreover, HS- DPCCH power offset settings for both CQI and HARQ-ACK fields that may be modified and/or created to ensure reliable uplink feedback transmission.
