Abstract
In an example method, a UE receives modulated data transmitted from a base station in a given subframe, and searches through the received modulated data to find the physical control format indicator channel (PCFICH) of the given subframe. The searching is based on the PCFICH having a predefined structure. Upon thereby finding the PCFICH of the given subframe, the UE determines the control format indicator (CFI) carried by the PCFICH of the given subframe. The UE then uses the CFI carried by the PCFICH of the given subframe as a basis to read a portion of a downlink control channel of the given subframe.
