  • Outer loop power control method and apparatus for wireless communication systems
    Patent number: 7558593
    Abstract: An adjustment of the target signal to interference ratio (SIRtarget) at the start of each transmission (N) uses an Outage-Based OLPC method, which establishes the ratio (SIRtarget) as the sum of a first component (SIRoutage-tgt) that adjusts quickly to the conditions of the communications channel and a second component (SIRBLER-tgt) that is adjustable according to a target block error rate (BLERtarget) The stored values of the two components (SIRoutage-tgt, SIRBLER-tgt) in at least one prior transmission (N?1) are used obtain convergence of the target ratio (SIRtarget) by setting the initial value in the transmission (N) for the first component (SIRoutage-tgt) equal to a value higher than the average values for the first component (SIRoutage-tgt) and setting the initial value in said transmission (N) for the second component (SIRBLER-tgt) and setting the initial value in said transmission (N) for the second component (SIRBLER-tgt) equal to the average of the values of the second component (SIRBLER-tgt).

  • Outer loop power control method and apparatus for wireless communication systems
    Publication number: 20070218933
    Abstract: The invention allows a quick adjustment of the target signal to interference ratio (SIRtarget) at the start of each transmission (N) using the method known as Outage-Based OLPC, which establishes said ratio (SIRtarget) as the sum of two components, a first component (SIRoutage-tgt) that adjusts quickly to the conditions of the communications channel and a second component (SIRBLER-tgt) adjustable according to a target block error rate (BLERtarget) wherein, having stored the values of the two components (SIRoutage-tgt, SIRBLER-tgt) in at least one prior transmission (N?1), to obtain a fast initial convergence of the target ratio (SIRtarget) the following is established: the initial value in said transmission (N) for the first component (SIRoutage-tgt) setting it equal to a value clearly higher than the average values for said component (SIRoutage-tgt); and the initial value in said transmission (N) for the second component (SIRBLER-tgt) setting it equal to the average of the values of said component (SIRBL
