摘要： This application relates to an antenna apparatus and an electronic device. The 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 and the second branch are each configured as an axisymmetric structure. A symmetry axis of the first branch coincides with a first center line of the first gap, a symmetry axis of the second branch is parallel to the first center line and is spaced from the first center line by a first distance, and the first center line is a center line that is of the first gap and that is perpendicular to a length direction of the frame branch. A first end that is of the first frame branch and that is away from at least the first gap is electrically connected to a reference ground, and a first end that is of the second frame branch and that is away from the first gap is electrically connected to the reference ground. According to the antenna apparatus and the electronic device provided in this application, intra-frequency decoupling between the second frame branch and the second branch is implemented.

摘要： This application discloses a congestion control method and an apparatus. In this application, 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, where the indication information indicates the receiving device to send a signaling packet, to trigger the sending device to add the quota for the at least one of the unscheduled packet send window and the scheduled packet send window corresponding to the first flow. According to this application, a network latency can be reduced.

摘要： An embodiment of this application provides an electronic device, including a wire loop antenna or a slot loop antenna. When the wire loop antenna or the slot loop antenna is symmetrical at a radiator or an annular slot of the wire loop antenna or the slot loop antenna, a common mode and a differential mode can be respectively excited through symmetrical feed and anti-symmetrical feed. Because radiation generated by the two modes is integrally orthogonal in a far field, there is good isolation between two feed units, so that a co-radiator dual-antenna structure can be formed. In addition, when asymmetrical feed is performed on the wire loop antenna or the slot loop antenna provided in this embodiment of this application, the common mode and the differential mode can be simultaneously excited. A plurality of operating modes of the antenna are used to extend an operating bandwidth of the antenna, so that the antenna covers a larger frequency range with a limited volume.

摘要： 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. In this way, good antenna performance can be ensured, so that the electronic device can fully use the antenna unit in limited space to implement various scenarios, to improve utilization of antenna space.
