A method for wireless communications testing using downlink "DL" signal transmissions from an access point to a mobile terminal and uplink "UL" signal transmissions from said mobile terminal to said access point, comprising: performing a DL signal transmission including DL control information with a signal transmission control parameter related to a first maximum number of transmissions of each one of a plurality of successive DL data blocks in subsequent DL signal transmissions, wherein said first maximum number equals unity; testing block error rate and throughput, including performing said subsequent DL signal transmissions, wherein no transmission of any one of said plurality of successive DL data blocks exceeds said first maximum number, and performing each one of a plurality of UL signal transmissions responsive to a respective one of said subsequent DL signal transmissions and including a positive UL acknowledgment "ACK" for each one of said successive DL data blocks that has been successfully decoded and a negative UL acknowledgment "NACK" for each one of said successive DL data blocks that has been unsuccessfully decoded; and following said block error rate and throughput testing, performing another DL signal transmission including further DL control information with said signal transmission control parameter related to a second maximum number of transmissions of each one of second successive DL data blocks in a subsequent plurality of DL signal transmissions, wherein said second maximum number is greater than said first maximum number. performing a DL signal transmission including DL control information with a signal transmission control parameter related to a first maximum number of transmissions of each one of a plurality of successive DL data blocks in subsequent DL signal transmissions, wherein said first maximum number equals unity; testing block error rate and throughput, including performing said subsequent DL signal transmissions, wherein no transmission of any one of said plurality of successive DL data blocks exceeds said first maximum number, and performing each one of a plurality of UL signal transmissions responsive to a respective one of said subsequent DL signal transmissions and including a positive UL acknowledgment "ACK" for each one of said successive DL data blocks that has been successfully decoded and a negative UL acknowledgment "NACK" for each one of said successive DL data blocks that has been unsuccessfully decoded; and performing said subsequent DL signal transmissions, wherein no transmission of any one of said plurality of successive DL data blocks exceeds said first maximum number, and performing each one of a plurality of UL signal transmissions responsive to a respective one of said subsequent DL signal transmissions and including a positive UL acknowledgment "ACK" for each one of said successive DL data blocks that has been successfully decoded and a negative UL acknowledgment "NACK" for each one of said successive DL data blocks that has been unsuccessfully decoded; and a positive UL acknowledgment "ACK" for each one of said successive DL data blocks that has been successfully decoded and a negative UL acknowledgment "NACK" for each one of said successive DL data blocks that has been unsuccessfully decoded; and following said block error rate and throughput testing, performing another DL signal transmission including further DL control information with said signal transmission control parameter related to a second maximum number of transmissions of each one of second successive DL data blocks in a subsequent plurality of DL signal transmissions, wherein said second maximum number is greater than said first maximum number.
