摘要： A method and apparatus for transmitting and receiving a Sounding Reference Signal (SRS) to a network in a communication system. A bandwidth allocated by the network to transmissions of one or more random access channels is determined. An SRS bandwidth configuration is reconfigured by setting a maximum bandwidth value of the SRS bandwidth configuration to a value that avoids overlapping the bandwidth allocated to transmissions of the one or more random access channels. The SRS is transmitted in accordance with a bandwidth from the reconfigured SRS bandwidth configuration. Information regarding the SRS bandwidth configuration is provided to a User Equipment (UE) by the network.
