Claim Text:
1. A method for communication, comprising: communicating over the air with user equipment (UE) in a frequency domain duplexing (FDD) mode, which defines a downlink channel comprising a first set of time-frequency resources in a first frequency range and an uplink channel comprising a second set of time-frequency resources, comprising multiple physical resource blocks (PRBs) in multiple time periods, in a second frequency range, which has two channel edges and is disjoint from the first frequency range; identifying an excess capacity in the uplink channel; allocating at least a portion of the excess capacity for downlink communication by assigning a subset of the time-frequency resources in the second frequency range to the downlink communication, wherein the subset does not comprise at least the PRBs at both of the channel edges in at least one of the time periods; and communicating over the air with at least one UE by transmitting downlink information using the assigned subset of the time-frequency resources in the second frequency range.
