Abstract: A chip slot is disclosed, which includes a slot, where a plurality of terminal groups are disposed in the slot, terminals in each terminal group include metal sheets that are symmetrically disposed on two opposite inner side walls of the slot, and each metal sheet has a bending pin that extends outside the slot; bending directions of bending pins on the terminals in each terminal group are same; and for any row of metal sheets in any two adjacent terminal groups, along an arrangement direction of the row of metal sheets, bending pins of the metal sheets in the adjacent terminal groups are alternately arranged on both sides of the row of metal sheets. The bending pins of the row of metal sheets are bent toward two different directions.

Abstract: One example method includes transmitting a test signal through the transmit channel n, where the test signal is radiated by a service antenna element n corresponding to the transmit channel n and is received by a calibration antenna element in the phased array antenna. N coupling signals received by N calibration antenna elements coupled to the service antenna element n can then be obtained. Delay weighting can then be performed on the N coupling signals based on relative positions of the service antenna element n and each of the N calibration antenna elements to obtain N calibration signals. The N calibration signals can then be combined into the calibration signal corresponding to the transmit channel n. Calibration signals corresponding to all transmit channels in the phased array antenna can then be obtained. At least one of amplitudes or phases of the transmit channels can then be compensated for.

Abstract: The present disclosure relates to methods and devices for discovering a Bluetooth device. One example method includes receiving, by a second Bluetooth device, a first broadcast frame from a first Bluetooth device, determining, by the second Bluetooth device, whether the first broadcast frame includes first indication information, and if the first broadcast frame includes the first indication information, sending, by the second Bluetooth device, at least one second broadcast frame within a preset time period after receiving the first broadcast frame The second broadcast frame includes second indication information, and the second indication information is used to instruct a Bluetooth device receiving the second broadcast frame to exchange information with the second Bluetooth device.

Abstract: Embodiments of the present application relate to the communications field and disclose a calibration method and a communications device, capable of compensating for measured amplitude and phase results. The method includes determining a position error of each of the N antenna groups, and then determining an actual position of the antenna group based on a target position of the antenna group and the position error of the antenna group. A phase compensation value and/or an amplitude compensation value of the antenna group are determined for a target probe of the second device based on the actual position of the antenna group. Based on the phase compensation value and/or the amplitude compensation value of the antenna group, compensating is performed for a phase result and/or an amplitude result that are/is obtained by the target probe of the second device by measuring a signal transmitted by the antenna group.
