Abstract
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.
Claims27
A method for a User Equipment (UE) to transmit a Sounding Reference Signal (SRS) to a network in a communication system, comprising steps of:
- determining a bandwidth allocated by the network to transmissions of one or more random access channels;
- reconfiguring an SRS bandwidth configuration 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;
- and
- transmitting the SRS in accordance with a bandwidth from the reconfigured SRS bandwidth configuration,
- wherein information regarding the SRS bandwidth configuration is provided to the UE by the network.
A method for a network to receive a Sounding Reference Signal (SRS) from a User Equipment (UE) in a communication system, comprising steps of:
- allocating a bandwidth to transmissions of one or more random access channels;
- transmitting the allocated bandwidth and an SRS bandwidth configuration to the UE;
- receiving an SRS transmission in accordance with a bandwidth from a reconfigured SRS bandwidth configuration, which was reconfigured by the UE 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.
A User Equipment (UE) for transmitting a Sounding Reference Signal (SRS) to a network in a communication system, comprising:
- a sub-carrier mapper for determining a bandwidth allocated by a network to transmissions of one or more random access channels, reconfiguring an SRS bandwidth configuration 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, and transmitting the SRS in accordance with a bandwidth from the reconfigured SRS bandwidth configuration, wherein information regarding the SRS bandwidth configuration is provided to the UE by the network.
A network for receiving a Sounding Reference Signal (SRS) from a User Equipment (UE) in a communication system comprising:
- a sub-carrier mapper for allocating a bandwidth to transmissions of one or more random access channels;
- a transmitter for transmitting the allocated bandwidth and an SRS bandwidth configuration to the UE;
- and
- a receiver for receiving an SRS transmission in accordance with a bandwidth from a reconfigured SRS bandwidth configuration, which was reconfigured by the UE 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.
