摘要
Systems and methodologies are described that facilitate conveying decoding statuses in a wireless communication environment. A UE can transmit a plurality of codewords as part of an uplink multiple-input multiple-output (MIMO) transmission to a base station. The base station can receive and attempt to decode the plurality of codewords. Further, decoding statuses for the plurality of codewords can be determined. Moreover, the decoding statuses for the plurality of codewords can be signaled to the UE. For example, the decoding statuses for the plurality of codewords can be conveyed via a single PHICH. According to another example, multiple PHICHs can convey the decoding statuses. Pursuant to a further example, the decoding statuses can be conveyed at least in part via a PDCCH.
