Concurrent Transmission of Multiple Acknowledge/Not Acknowledge and Scheduling Request Indicator in Time Division Duplex Uplink Signaling

摘要

This invention is a transmission scheme for multi-ACK/NAK and SRI in TDD. The described scheme enables using DAI as pure counter. QPSK is adopted as the modulation scheme in this invention which guarantees satisfactory detection performance. Link level simulations show that the event of one DL grant pass followed by three consecutive DL grant misses is of low probability.
