One example method includes obtaining, by a first network device, N pieces of first round-trip time in a first periodicity. The first round-trip time is time consumed when the first network device and a second network device each transmit a packet once through an Xn/X2 interface. A minimum first round-trip time reference value is determined based on the N pieces of first round-trip time. The minimum first round-trip time reference value is a smallest value of the N pieces of first round-trip time. An inter-site synchronization offset value of the first periodicity is determined based on the minimum first round-trip time reference value. The inter-site synchronization offset value of the first periodicity is an inter-site synchronization offset value that exists when the first network device and the second network device transmit packets through the Xn/X2 interface.

  • Patent number: 11482708
    Abstract: An anode includes a mixed ionic-electronic conductor (MIEC) with an open pore structure. The open pore structure includes open pores to facilitate motion of an alkali metal into and/or out of the MIEC. The open pore structure thus provides open space to relieve the stresses generated by the alkali metal when charging/discharging a battery. The MIEC is formed from a material that is thermodynamically and electrochemically stable against the alkali metal to prevent the formation of solid-electrolyte interphase (SEI) debris and the formation of dead alkali metal. The MIEC may also be passive (the MIEC does not store or release alkali metal). In one example, the open pore structure may be an array of substantially aligned tubules with a width less than about 300 nm, a wall thickness between about 1 nm to about 30 nm, and a height of at least 10 um arranged as a honeycomb.
