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

    • The present invention relates to a communication node (1) with at least one antenna arrangement (2, 3, 4) having four first antenna devices (5, 7, 9, 11) with corresponding antenna port pairs (A, B, C, D). Each pair of antenna ports (A, B, C, D) comprising a corresponding first antenna port (P1A, P1B, P1C, P1D) for a first polarization (P1) and second antenna port (P2A, P2B, P2C, P2D) for a second orthogonal polarization (P2). A beamforming arrangement (17) comprises four beam ports (18, 19, 20, 21) and is configured to apply beam weights (a 1 , a 2 , a 3 , a 4 ; b 1 , b 2 , b 3 , b 4 ; b ∗ 4 , b ∗ 3 , b ∗ 2 , b ∗ 1 ; −a ∗ 4 , −a ∗ 3 , −a ∗ 2 , −a ∗ 1 ; c 1 , c 2 , c 3 , c 4 ; d 1 , d 2 , d 3 , d 4 ; d ∗ 4 , d ∗ 3 , d ∗ 2 , d ∗ 1 ; −c ∗ 4 , −c ∗ 3 , −c ∗ 2 , −c ∗ 1 ) to each one of the antenna ports (P1A, P1B, P1C, P1D; P2A, P2B, P2C, P2D). For corresponding beam ports (18, 19, 20, 21), a first set of beam weights (a 1 , a 2 , a 3 , a 4 ), third set of beam weights (c 1 , c 2 , c 3 , c 4 ), fifth set of beam weights (b ∗ 4 , b ∗ 3 , b ∗ 2 , b ∗ 1 ) and seventh set of beam weights (d ∗ 4 , d ∗ 3 , d ∗ 2 , d ∗ 1 ) are applied to the first antenna ports (P1A, P1B, P1C, P1D). For corresponding beam ports (18, 9, 20, 21), a second set of beam weights (b 1 , b 2 , b 3 , b 4 ), fourth set of beam weights (d 1 , d 2 , d 3 , d 4 ), sixth set of beam weights (−a ∗ 4 ,−a ∗ 3 , −a ∗ 2 , −a ∗ 1 ) and eighth set of beam weights (−c ∗ 4 , −c ∗ 3 , −c ∗ 2 , −c ∗ 1 ) are applied to the second antenna ports (P2A, P2B, P2C, P2D). The third set of beam weights (c 1 , c 2 , c 3 , c 4 ) and fourth set of beam weights (d 1 , d 2 , d 3 , d 4 ) are chosen such that a phase center separation is accomplished between the corresponding beam ports (18, 19). The fifth, sixth seventh and eighth set of beam weights are a function of the complex conjugate of the second, first, fourth and third sets of beam weights, correspondingly. The present invention also relates to a corresponding method.
