Abstract: The present patent application provides a method, an apparatus, and a system for generating a timestamp. The method includes: receiving, by a data packet processing unit, a data packet sent by a physical layer transceiver unit or an upper layer, and identifying whether the data packet is a precise time synchronization protocol PTP data packet, and if the data packet is a PTP data packet, generating, according to a physical layer delay provided by a physical layer delay acquiring unit and a non-physical layer delay provided by a non-physical layer delay acquiring unit, a precise timestamp and rewriting a timestamp field in the data packet.

Abstract: A tightly coupled array antenna and a network device are provided. The tightly coupled array antenna includes a first dielectric slab and a plurality of antenna units printed on a lower surface of the first dielectric slab. Each of the antenna units includes a plurality of dipole antennas that are disposed at intervals. Oscillator arms of the dipole antennas are partially hollowed out to reduce both capacitance formed between the oscillator arms and the first dielectric slab and the cross-sectional area of a current path. A plurality of coupling structures is provided on an upper surface of the first dielectric slab so that each of the antenna units is electrically connected to one coupling structure.

Abstract: The present invention discloses a method for reducing inter-Femtocell interference, including: obtaining an average channel gain of all available channels; determining whether the average channel gain is greater than a preset threshold; if the average channel gain is greater than the preset threshold, determining, by using spectrum sensing, a P channel and an N channel, where the P channel is one or more available channels causing greatest interference and the N channel is one or more available channels suffering greatest interference; and transmitting or receiving a signal in an available channel other than the P channel and the N channel.
