A method is provided for applying HOM to a PDCCH to transmit control information from an access node to a UE. The method comprises: selecting a DCI format for a HOM PDCCH; determining a DCI block of the HOM PDCCH according to the selected DCI format; generating a sequence of coded bits to be transmitted from the DCI block; multiplexing the sequence of coded bits of the HOM PDCCH with coded bits of other PDCCHs to form a sequence of multiplexed bits; scrambling the sequence of multiplexed bits to form a sequence of scrambled bits; modulating the scrambled bits to form a sequence of modulation symbols; and transmitting the sequence of modulation symbols, where a PDCCH is transmitted on an aggregation of one or more CCEs.

A system and method for adaptively managing frame size in a wireless multihop network (100) is disclosed. In one embodiment, a packet is transmitted from a source to a destination (420). A acknowledgement packet (422) is received and a successful acknowledgement packet counter is incremented if the acknowledgement packet arrives prior to a time-out of a timer (444). A frame size is increased if the successful acknowledgement packet counter reaches a specified value (446, 448). If the acknowledgement packet arrives after the time-out of the timer, the successful acknowledgement packet counter (460) is reset and the frame size (462) is decreased. These procedures can be repeated until the frame size is greater than or equal to a maximum frame size (450) or less than or equal to a minimum frame size (464).
