    • Receiver resources are allocated based on how subframes are allocated within in a frame between downlink and uplink transmissions and how often the receiver is expected to report feedback information associated with the downlink transmissions. Additional time is available for processing received data blocks if the feedback information derived from those blocks must be reported later than expected due to the unavailability of uplink subframes. According to one embodiment, received signals are processed by receiving transmission configuration information indicating how downlink and uplink subframes are allocated within a frame in the time domain. Based on the transmission configuration information, the receiver determines whether a delay that exceeds a feedback reporting interval assigned to the receiver will occur when reporting feedback information associated with the downlink subframes. Receiver resources are allocated based on whether a delay will occur when reporting the feedback information.
