Abstract: Embodiments of the present disclosure provide an uplink control information transmission method, a terminal device, a base station, and a system. The transmission method includes the following steps: First, the terminal device determines an information bit sequence of to-be-transmitted uplink control information. Then, the terminal device determines a first sequence according to the information bit sequence, where the first sequence is a linear-phase complex exponential sequence. Finally, the terminal device sends the to-be-transmitted uplink control information to the base station by using an uplink control channel, where the uplink control channel occupies N symbols, N is a positive integer, a signal carried on a symbol l of the N symbols is directly proportional to a product of the first sequence and a second sequence, and the second sequence is a cyclic shift sequence.

Abstract: An address resolution method uniformly processing ARP broadcast packets by an address server to avoid broadcasting in the network, so that the occupied bandwidth is reduced. The method also includes storing by a network device and terminal address correspondence information of local and remote terminals in communication with one another, which reduces the size of the MAC table in the data center network, reduces the load of the network device, and improves the processing capabilities of the network device, so that it is possible to deploy a large layer-2 network to thereby solve real-time relocation problems of a virtual machine.
