METHOD FOR BATCH DATA TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM WITH HARQ WITH ADAPTIVE COMPENSATION OF BIAS OF QUALITY ASSESSMENT OF CHANNEL

摘要

FIELD: radio engineering, communication.;SUBSTANCE: invention relates to a method of data transmission in a wireless communication system with hybrid automatic request for repetition (HARQ). Assessment bias compensation CQI is performed by processing of HARQ receipts (7), a signal-code sequence (SCS) is chosen based on compensated assessment CQI, coding of a data batch (6) is performed by its help, after that, the first attempt of transmission of the batch of coded data to a receiver (4) is performed via a forward channel (2), the success of which is determined as per the type of HARQ receipt (7) received from the receiver (4) via a backward channel (3) in response to this attempt. In case the received HARQ receipt (7) is not positive, repeated attempt of batch transmission is performed via the forward channel (2). In order to provide the adaptive compensation of bias of assessment CQI, the first measure (S) is determined using at least two last HARQ receipts and based on it there determined is a value of a factor of coarse compensation, the second measure (T) is determined using at least one of the last HARQ receipts and based on it there determined is a value of a factor of fine compensation, a reset operation of the value of the fine compensation factor is performed till the initial value at the change of the current value of the coarse compensation factor and CQI assessment is changed considering values of the obtained values of the coarse compensation factor and the fine compensation factor.;EFFECT: providing control of the level of successful delivery of data from the first try of transmission; improving the efficient use of radio resources and speed of data transmission in a wireless communication system as a whole.;17 cl, 5 dwg
