Abstract
A User Equipment has an uplink buffer for storing uplink data to be sent to a base station in an uplink grant procedure and is configured with a DTX (Discontinuous Transmission) pattern which allows it to skip the transmission of uplink padding transmissions when there is a grant but no uplink data in the uplink buffer during ‘off’ periods.
Claims11
A method for operating a wireless communication device in communication with a network element of a cellular communication system, the method comprising the step of:
- the network element transmitting an indication in a DCI (Downlink Control Information) signal to a wireless communication device which is in communication with the network element,
- wherein the indication instructs the wireless communication device to skip sending uplink padding transmissions for a given uplink grant for dynamic scheduling grant.
A method for operating a wireless communication device in communication with a network element of a cellular communication system, wherein the wireless communication device has an uplink buffer for storing uplink data to be sent to the network element in an uplink grant procedure, the method comprising
- skipping the transmission of periodic Buffer Status Reports from a wireless communication device to a network element to which the wireless communication device is connected, when skipping of uplink padding transmissions is enabled and no uplink data is being sent.
A method for operating a wireless communication device in communication with a network element of a cellular communication system, wherein the wireless communication device has an uplink buffer for storing uplink data to be sent to the network element in an uplink grant procedure, the method comprising skipping the transmission of uplink padding transmissions from the wireless communication device to the network element when there is a grant but no uplink data in said uplink buffer, and releasing any configured uplink resources after expiry of a predetermined period of time following activation of such configured uplink resources.
A method for operating a wireless communication device in communication with a network element of a cellular communication system, wherein the wireless communication device has an uplink buffer for storing uplink data to be sent to the network element in an uplink grant procedure, the method comprising;
- configuring the wireless communication device with a DTX (Discontinuous Transmission) pattern, skipping the transmission of uplink padding transmissions from the wireless communication device to the network element during ‘off’ periods if there is a grant but no uplink data in said uplink buffer, and forbidding skipping transmissions during ‘on’ periods if there is a grant.
A wireless communication device adapted for communication with a network element of a cellular communication system, wherein the wireless communication device has an uplink buffer for storing uplink data to be sent to the network element in an uplink grant procedure and is configured with a DTX (Discontinuous Transmission) pattern and allowed to skip the transmission of uplink padding transmissions to the network element during ‘off’ periods if there is no uplink data in said uplink buffer.
