Abstract:
A wireless electronic device includes a ground plane including a plurality of slots located along an edge of the ground plane. A dielectric layer is on the ground plane. A stripline on the dielectric layer is opposite the ground plane, positioned to overlap one of the plurality of slots. The stripline is further positioned to not overlap slots adjacent the one of the plurality of slots that the stripline overlaps. The wireless electronic device is configured to resonate at a resonant frequency when excited by a signal transmitted and/or received though the stripline.

Abstract:
The present invention relates to a method for operating a base station (21) in a wireless radio network. The base station (21) comprises a plurality of antennas (22) for transmitting radio frequency signals between the base station (21) and a user equipment (UE1, UE2, UE3). According to the method, at each antenna (22) a training signal sent from the user equipment at a first point in time (t1) is received and for each antenna a corresponding first configuration parameter (P1) is determined based on the training signal received at the corresponding antenna at the first point in time (t1). Furthermore, at each antenna (22) a training signal sent from the user equipment at a second point in time (t2), which is different from the first point in time (t1), is received and for each antenna (22) a corresponding second configuration parameter (P2) is determined based on the training signal received at the second point in time (t2). For each antenna (22) a corresponding predicted configuration parameter (P3) is determined based on the first and second configuration parameters (P1, P2).

The present invention relates to a method for transmitting data between a user equipment (15) and a base station (11) in a wireless radio network (10). The user equipment (15) comprises at least a first antenna (16) and a second antenna (17). The base station (11) comprises a plurality of antennas (12) for transmitting radio frequency signals between the base station (11) and the user equipment (15). According to the method, a first training signal is transmitted from the user equipment (15) to the base station (11) via the first antenna (16) at a first time period. Furthermore, a second training signal is transmitted from the user equipment (15) to the base station (11) via the second antenna (17) at a second time period different to the first time period. For each antenna (12) of the base station (11) a corresponding first configuration parameter is determined based on the first training signal and a corresponding second configuration parameter is determined based on the second training signal. Furthermore, first downlink data (DL1) is transmitted from the base station (11) to the user equipment using the first configuration parameters and simultaneously second downlink data (DL2) are transmitted from the base station (11) to the user equipment (15) using the second configuration parameters. Then, a first signal quality parameter of the first downlink data (DL1) is determined and a second signal quality parameter of the second downlink data (DL2) is determined. Based on the determined first and second signal quality parameters, an antenna of the first and second antennas (16, 17) of the user equipment (15) is selected for transmission of uplink data (UL1, UL2) from the user equipment (15) to the base station (11).

Abstract:
A wireless electronic device includes an inverted-F antenna (IFA) having an IFA exciting element, an IFA feed, and a grounding pin. The IFA exciting element is configured to resonate at a resonant frequency when excited by a signal received through the IFA feed. The wireless electronic device includes a choke notch having a length defined based on the resonant frequency of the IFA exciting element. The choke notch is electrically coupled to the IFA exciting element through the grounding pin. A ground patch is electrically coupled between the choke notch and the ground plane.

Abstract:
A beam sweep configuration of at least one beam sweep is exchanged between nodes of a network. The beam sweep configuration may be indicative of a time-duplex configuration of a plurality of beams of the at least one beam sweep. A beam configuration may be determined based on a receive property of pilot signals transmitted and/or received in the beam sweep.
