Abstract
The teachings presented herein propose a separation between the configuration of a sounding signal, and the initialization of the sounding signal. In other words, in at least one example embodiment proposed herein, a base station or other controlling entity sends, to a mobile station, an explicit or implicit indication that causes the mobile station to transmit a sounding signal according to sounding signal configuration parameters that at least a portion of which were previously and separately sent to the mobile station.
Claims31
A method of controlling the transmission of sounding signals by a mobile station operating in a wireless communication network the method comprising:
- sending configuration parameters for a sounding signal to be transmitted by the mobile station;
- and
- subsequently sending a command or other initiating signal to the mobile station separately from said configuration parameters, to cause the mobile station to transmit the sounding signal according to said configuration parameters.
A base station configured to control the transmission of sounding signals by a mobile station, said base station comprising one or more processing circuits configured to:
- send configuration parameters for a sounding signal to be transmitted by the mobile station;
- and
- subsequently send a command or other initiating signal to the mobile station separately from said configuration parameters, to cause the mobile station to transmit the sounding signal according to said configuration parameters.
A mobile station configured for operation in a wireless communication network and comprising one or more processing circuits configured to:
- receive configuration parameters for a sounding signal to be transmitted by the mobile station;
- and
- subsequently transmit a sounding signal in accordance with the configuration parameters, in response to receiving a separate command or other initiating signal.
A method of controlling sounding signal transmission by a mobile station operating in a wireless communication network, the method comprising:
- sending an indication to a mobile station, separately from configuration parameters for a sounding signal to be transmitted by the mobile station, to transmit the sounding signal according to the configuration parameters, wherein the configuration parameters are sent to the mobile station via a downlink.
A base station configured to control sounding signal transmission by a mobile station, the base station comprising one or more processing circuits configured to:
- send an indication to the mobile station, separately from configuration parameters for a sounding signal to be transmitted by the mobile station, to transmit the sounding signal according to the configuration parameters, wherein the configuration parameters are sent to the mobile station via a downlink.
A non-transitory computer readable medium comprising a computer program stored thereon, the computer program comprising instructions that, when executed by processing circuitry in a base station configured to control sounding signal transmission by a mobile station, causes the base station to:
- send an indication to the mobile station, separately from configuration parameters for a sounding signal to be transmitted by the mobile station, to transmit the sounding signal according to the configuration parameters, wherein the configuration parameters are sent to the mobile station via a downlink.
