1. A base station configured to:
decode, by a receiver of the base station, a first part of a codeword received from a user equipment;
detect a second part of the received codeword using a multi-user detector;
determine if the decoding of the first part of the codeword is successful; and
1) based on the determination that the decoding of the first part of the codeword is successful, send an acknowledgement to the user equipment; or
2) based on the determination that the decoding of the first part of the codeword is not successful and the detection of the second part of the codeword is successful:
combine the first part and the second part of the codeword to form a combined codeword;
decode the combined codeword;
determine if the decoding of the combined codeword is successful; and
i) based on the determination that the decoding of the combined codeword is successful, send an acknowledgement to the user equipment; or
ii) based on either the decoding of the first part of the codeword not being successful or the decoding of the combined codeword not being successful, send a negative acknowledgement to the user equipment.
