    Abstract: A communications apparatus includes a phase correction unit, a first radio frequency channel, a first analog bridge, a second radio frequency channel, and a second analog bridge. A first signal is sent to a first input end using the first radio frequency channel, and is divided into at least two channels of first sub-signals by using the first analog bridge. The at least two channels of first sub-signals are respective output from at least two first output ends to at least two first antenna arrays. Similarly, a second signal is divided into at least two channels of second sub-signals by using the second analog bridge, and the at least two channels of second sub-signals are output to at least two second antenna arrays. A first channel of first sub-signal and a first channel of second sub-signal are coupled to the phase correction unit by using a coupler.

    Abstract: A synchronization method including: receiving, by a terminal, a system message on a first downlink carrier, where the system message includes first indication information and second indication information, the first indication information indicates a frequency domain range of a first uplink carrier, the second indication information indicates a frequency domain range of a second downlink carrier, and a frequency of the first uplink carrier is presynchronized with a frequency of the second downlink carrier; and receiving, by the terminal, a synchronization signal on the second downlink carrier, to implement frequency synchronization with the first uplink carrier. According to the synchronization method in NR-LTE co-existence, a terminal can implement frequency synchronization with an LTE uplink carrier, so that the terminal can perform uplink transmission by using a frequency domain resource in the LTE uplink carrier.

    Abstract: A heat sink includes a base and a plurality of fins. A root of the fin is connected to the base. A heated area, a dropping pipe, and a spacing strip between the heated area and the dropping pipe are formed in the fin. A first passage and a second passage are formed between the heated area and the dropping pipe. A hydraulic diameter of a pipeline in the heated area is less than a critical dimension. A hydraulic diameter of a pipeline of the dropping pipe is greater than or equal to the critical dimension, and a pressure of liquid at an intersection of the second passage and the dropping pipe is greater than a pressure of liquid at an intersection of the second passage and the heated area.

    Abstract: Embodiments of the present invention disclose a sounding reference symbol SRS transmission method and a radio remote unit. The method, performed by a radio remote unit, includes: receiving a plurality of pieces of sampled data in a first period by using each antenna of an antenna array; if all of the plurality of pieces of sampled data are the SRS sampled data, buffering the plurality of pieces of sampled data; and reading the plurality of pieces of sampled data from the buffer in a second period, and sending the read plurality of pieces of sampled data to a baseband processing unit, where duration of the second period is longer than duration of the first period. Thus according the embodiments of the present invention, a time for transmitting the SRS sampled data is prolonged, so that bandwidth required for transmitting the SRS sampled data can be reduced.

    Abstract: A message sending method, a mobile broadband (MBB) device, and a host, where the method includes receiving, by an MBB device, authentication information sent by a host, requesting, by the MBB device, authentication from a notification server according to the authentication information, to establish a transmission path between the MBB device and the notification server, determining, by the MBB device, a message required to be transmitted to the host, and sending, by the MBB device, the message to the notification server using the transmission path such that the notification server sends the message to the host. The message can be actively pushed to the host when the message required to be transmitted to a host is determined such that signaling overheads can be significantly reduced, and power consumption can be reduced.
