    Abstract: Disclosed is a sounding reference signal transmission method which is efficient in an uplink wireless telecommunications system using a multiple antenna technique and sounding reference signal hopping. A terminal is equipped with a plurality of antennas, and a base station receives the sounding reference signal transmitted from these antennas and estimates the uplink channel state of each antenna. The sounding reference signal performs frequency hopping so that the base station determines the channel condition for the entire bandwidth to which data is transmitted in the uplink system. In this environment, the sounding reference signal is transmitted through an antenna pattern through the entire data transmission bandwidth of the uplink system for each antenna of the terminal without additional overhead.

    Abstract: A communication method and apparatus where the method includes: a network device that receives a random access request from a terminal device; and the network device sends a random access response to the terminal device, where the random access response includes scheduling information of a message 3 that includes first information that a request that the terminal device repeatedly transmit the message 3 by using same transmit power and a same precoding matrix. In response to repeatedly transmitting the message 3, the terminal device with the same transmit power and the same precoding matrix, so that stability of transmission of the message 3 is improved, and a transmission success rate of the message 3 is improved, thereby improving an access success rate of a random access procedure of the terminal device.
