Abstract:
1. A soft migration method for reallocating a portion of a first frequency band allocated to a first radio access technology (RAT) to a second RAT in a wireless communication network, comprising: determining a migration block granularity for reallocating the portion of the first frequency band to the second RAT; a plurality of non-contiguous spectrum blocks of the determined granularity in the first frequency band, wherein the plurality of non-contiguous spectrum blocks is between a first spectrum block allocated to the first RAT and a second spectrum block allocated to the first RAT; aggregating the plurality of non-contiguous spectrum blocks with a native carrier of the second RAT in a second frequency band allocated to the second RAT; controlling the aggregated plurality of non-contiguous spectrum blocks via the native carrier of the second RAT, and wherein controlling comprises providing control information to a user equipment (UE) for obtaining UE data.
