Abstract
According to some embodiments, a method of synchronizing a wireless device with a network node comprises receiving a radio subframe transmitted from the network node. The radio subframe comprises a first Primary Synchronization Signal (PSS) associated with a first Orthogonal Frequency Division Multiplexing (OFDM) symbol and a first plurality of subcarriers. The first PSS is paired with a first Secondary Synchronization Signal (SSS) associated with a second OFDM symbol and the first plurality of subcarriers. The radio subframe also comprises a second PSS associated with the first OFDM symbol and a second plurality of subcarriers. The second PSS is paired with a second SSS associated with the second OFDM symbol and the second plurality of subcarriers. The method further comprises inspecting the first plurality of subcarriers to detect the first PSS and the first SSS and inspecting the second plurality of subcarriers to detect the second PSS and the second SSS. Upon detecting at least one of the first PSS and the first SSS or the second PSS and the second SSS, the method determines system information associated with the network node based on the detected at least one PSS and the detec…
