Abstract
An adaptive modulation and coding (AMC) scheme integrated with multi-code transmission for high speed downlink packet access (HSDPA) is presented and some modulation and coding scheme (MCS) selection criteria are proposed to maximize single user data rates. Based on link-level performance analysis, the MCS selection criteria are proposed with the constraints of quality of service (QoS) requirement, modulation level, channel coding rate and the number of available channelization codes. By allowing multiple transmission parameters to change, these criteria make the scheme more flexible to the time-varying mobile channel with comparatively low complexity through a look-up table method. The AMC scheme is sensitive to the changes of channel condition and can save the channelization codes in an applicable way by applying these criteria.
