Abstract: A weight determining method and a related apparatus, to reduce a beam gain loss caused by a beam selection deviation are described. The method includes receiving an uplink reference signal and obtaining a channel reciprocity parameter between an uplink channel and a downlink channel based on the uplink reference signal. The method further includes determining state information of the downlink channel based on the channel reciprocity parameter, carrier frequency information of the uplink channel, and carrier frequency information of the downlink channel. Moreover, the method includes determining a weight of a downlink reference signal based on the state information of the downlink channel.

Abstract: The technology of this application relates to a shielding piece, a female connector, and a connector assembly. The shielding piece includes a main body and a contact portion, and the contact portion is connected to the main body by using at least two elastic arms or a connecting portion. The connecting portion surrounds the contact portion, and forms, jointly with the contact portion, a convexity protruding from the main body. The at least two elastic arms are connected to the main body at a periphery of the contact portion along different directions, and a gap is formed between the main body and the at least two elastic arms. The contact portion is configured to abut against a ground terminal of a male connector.

Abstract: A connector includes a base structure in one embodiment. At least one first via hole is disposed between a first surface and second surface of the base structure. The first surface has a first metal layer and a first clearance region that is in one-to-one correspondence with the at least one first via hole. The first clearance region is of a ring-shaped structure. The first via hole is located in a region encircled by the corresponding first clearance region. The first clearance region does not overlap the first metal layer. The second surface has a second metal layer and a second clearance region that is in one-to-one correspondence with the at least one first via hole. The second clearance region is of a ring-shaped structure. The first via hole is located in a region encircled by the corresponding second clearance region. The second clearance region does not overlap the second metal layer.
