Claim Text:
1. A wireless communication method, comprising: receiving a plurality of codewords; transmitting a downlink feedback message by spatially bundling acknowledgments for the received plurality of codewords in a plurality of Physical Hybrid Automatic Repeat Request (ARQ) Indicator Channels (PHICH); and transmitting configuration data in a Physical Downlink Control Channel (PDCCH) accompanying the downlink feedback message in the PHICH to configure a wireless terminal to provide an uplink feedback response, wherein, based on the configuration data including information related to a downlink control information format for signaling in the PDCCH, one of: the signaling in the PDCCH overrides any settings conveyed by the PHICH when the signaling in the PDCCH uses a large payload downlink control information format, or the signaling in the PDCCH is interpreted using the downlink feedback message in the PHICH when the signaling in the PDCCH uses a compact payload downlink control information format, wherein the signaling in the PDCCH is interpreted to configure the wireless terminal to operate in a single antenna mode when the downlink feedback message in the PHICH acknowledges the plurality of codewords are received.
