Abstract: This application provides an antenna unit and an electronic device. A signal at a C-mode port and a signal at a D-mode port of a same loop antenna in any antenna unit are respectively excited by using two feeds, and the antenna unit is electrically symmetrically disposed, so that the signal at the C-mode port is self-cancelled at the D-mode port, and the signal at the D-mode port is self-cancelled at the C-mode port, to implement signal isolation between the two ports and interference self-cancel, and the signal at the C-mode port and the signal at the D-mode port can be complementary to each other in different radiation directions, to implement two antennas with high isolation and a low envelope correlation coefficient ECC based on the same loop antenna.

Abstract: An antenna apparatus includes a first branch, a frame branch, and a second branch. The frame branch is provided with a first gap, and the frame branch is divided into a first frame branch and a second frame branch by the first gap. The first branch, the second branch, the first frame branch and the second frame branch are conductive, not in contact with each other and are insulated from each other A first feeding circuit is electrically connected to the second frame branch, configured to transmit a first excitation signal to the second frame branch, and excite the second frame branch to radiate a first radio wave. A second feeding circuit is electrically connected to the second branch, configured to transmit a second excitation signal to the second branch, and excite the second branch to radiate a second radio wave.

Abstract: Electronic devices and antenna structures are described. An example electronic device includes an antenna structure, wherein the antenna structure includes: a first radiator and a second radiator, wherein the first radiator includes a first end and a second end, and the second radiator includes a first end and a second end. The first end of the first radiator and the first end of the second radiator face each other and are not in contact with each other, and a slot is formed between the first end of the first radiator and the first end of the second radiator. The first radiator and the second radiator are disposed in a bent manner, and a spatial region formed between the first radiator, the second radiator, and the slot is T-shaped; and the second end of the first radiator is grounded, and the second end of the second radiator is grounded.

Abstract: A congestion control method and an apparatus are disclosed. The method includes: after a sending device generates an unscheduled data packet of a first flow, if it is determined, based on an unscheduled packet send window shared by all flows, that the unscheduled data packet meets a sending condition, determining whether to request to add a quota for at least one of the unscheduled packet send window and a scheduled packet send window corresponding to the first flow; and if it is determined that the quota is requested to be added for the at least one of the unscheduled packet send window and the scheduled packet send window corresponding to the first flow, setting indication information in the unscheduled data packet, and sending, to a receiving device, the unscheduled data packet in which the indication information is set.

Abstract: An antenna apparatus includes a circuit board and an antenna body. The antenna body includes a first radiator and a second radiator that are indirectly coupled. The first radiator comprises a first stub and a second stub that are opposite to, but do not touch each other to form a first gap, the first stub and the second stub are located on a first side edge of the circuit board, a second gap is configured between the first stub and the first side edge, and also between the second stub and the first side edge. The second radiator is located on the circuit board to form a third gap in-between. A vertical projection of the second radiator is located on the first surface. The first stub and the second stub are electrically connected to reference ground of the circuit board separately.
