Abstract:
1. A method of feedback in a wireless transmit receive unit (WTRU), the method comprising: the WTRU generating a feedback signal, the feedback signal comprising at least one of a precoding matrix index (PMI) or a channel quality index (CQI); the WTRU determining a number of bits of the feedback signal to be encoded; the WTRU selecting a type of error detection and correction scheme to apply to the feedback signal based on the number of bits of the feedback signal to be encoded, wherein selecting the type of error detection and correction scheme comprises selecting a number of error check (EC) bits to attach to the feedback signal and selecting a type of channel coding scheme to apply to the feedback signal and the selected number of EC bits; the WTRU encoding the feedback signal and the selected number of EC bits using the selected type of channel coding scheme; and the WTRU transmitting the encoded feedback signal.
