Abstract
Systems and methods for controlling sounding reference signal transmission are provided; a user equipment starts transmitting the sounding reference signal in anticipation of uplink data transmission, and then discontinues transmitting the sounding reference signal after completion of uplink data transmission.
Claims21
1-21. (canceled)
A method in a user equipment (UE), the method comprising:
- determining, by the UE, that the UE has uplink data to transmit;
- responsive to the determining, starting sounding reference signal transmissions using a set of sounding reference signal transmission resources;
- transmitting an uplink resource request after starting the sounding reference signal transmissions;
- transmitting the uplink data after transmitting the uplink resource request;
- and
- continuing the sounding reference signal transmissions until a completion of the transmission of the uplink data.
3 more elements
A user equipment (UE), comprising:
- a memory;
- and
- at least one hardware processor communicatively coupled with the memory and configured to:
- determine that the UE has uplink data to transmit;
- responsive to the determining, start sounding reference signal transmissions using a set of sounding reference signal transmission resources;
- transmit an uplink resource request after starting the sounding reference signal transmissions;
- transmit the uplink data after transmitting the uplink resource request;
- and
- continue the sounding reference signal transmissions until a completion of the transmission of the uplink data.
6 more elements
A non-transitory computer-readable medium containing instructions which, when executed, cause a user equipment (UE) to perform operations comprising:
- determining that the UE has uplink data to transmit;
- responsive to the determining, starting sounding reference signal transmissions using a set of sounding reference signal transmission resources;
- transmitting an uplink resource request after starting the sounding reference signal transmissions;
- transmitting the uplink data after transmitting the uplink resource request;
- and
- continuing the sounding reference signal transmissions until a completion of the transmission of the uplink data.
