Methods of hybrid ARQ and outer loop power control for the CDMA uplink

The present paper considers hybrid retransmission techniques in systems with closed loop power control, CDMA uplink for example. The known solution includes the threshold adjustment as a function of the decoding quality, i.e., the signal power is increased at unsuccessful decoding, and vice versa. The type 2 hybrid retransmission algorithm with puncturing to be used jointly with the threshold adjustment algorithm is proposed.
