Patent ID: 11483050

Abstract:
The present disclosure relates to an antenna system (1, 1′) comprising: —a first set of antenna ports (2), —a second set of antenna ports (3) separate from the first set of antenna ports (2), —a third set of antenna ports (28) that at least partly comprises each one of the first set of antenna ports (2) and the second set of antenna ports (3), —a transmitter arrangement (4, 4′), and —a receiver (5, 5′). The transmitter arrangement (4, 4′) comprises a first transmitter (4a, 4a′) adapted for transmission of signals by means of a first downlink communication resource (6, 38) via the first set of antenna ports (2) and a second transmitter (4b, 4b′) adapted for transmission of signals by means of a second downlink communication resource (7, 39) via the second set of antenna ports (3). The receiver (5, 5′) is adapted for reception of signals by means of a first uplink communication resource (6, 40) and a second uplink communication resource (7, 41) via the third set of antenna ports (28), where each communication resource defines, or is associated with, a certain bandwidth.
