the coderate adaptive change in a mobilfunkkommunikationssystem due to funkverbindungsmessungen on the welcome page

摘要

In an adaptive resending request control (ARQ) method and system in mobile radio communications, a reception side measures a line state in a line of a radio section, and selects, in accordance with the measurement result, the optimum packet resending control period and/or coding rate from an association table of measurement values and packet resending control periods/coding rates stored in advance to renew the control state and make the resending control period/coding rate variable so that an excellent delay characteristic and/or error correction can be achieved. In accordance with the line state of the radio section, the highest precision line state measuring method can be selected. IMAGE
