DETERMINATION OF HARQ/ACK CODEBOOK SIZE Russian patent published in 2016 - IPC H04L1/18 H04J3/00 

FIELD: wireless communication networks.

SUBSTANCE: invention relates to codebook determination of hybrid automatic requests of repetition (HARQ)-acknowledgement (ACK) in wireless communication networks. For this purpose downlink assignment index (DAI) is obtained; number of downlink subframes within packet window of first serving cell from multiple serving cells is determined, wherein downlink subframes of packet window are associated with uplink subframe for transmission of corresponding information of hybrid automatic request HARQ-ACK; number of HARQ-ACK bits is determined corresponding to first serving cell available in physical uplink shared channel (PUSCH) of uplink subframe based on DAI and certain number of downlink subframes; number of HARQ-ACK bits is determined corresponding to each of multiple serving cells available in PUSCH of uplink subframe; and HARQ-ACK codebook size in PUSCH of uplink subframe is determined based on a certain amount of HARQ-ACK bits corresponding to each of multiple serving cells.

EFFECT: effective reduction of non-productive costs of using HARQ-ACK.
