摘要： 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.

摘要： 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.
