Apparatus and method for deferring cell update messages from user equipment

A user equipment (UE) configured for spreading out over time transmission from the UE of a cell update request from a transmission of a cell update request from another UE, the UE comprising:

• means for receiving, while operating in a stand-by state, a broadcast message, wherein absence of an information element (IE) configured to turn on an enhanced uplink feature indicates the enhanced uplink feature is turned off;
• means for not keeping an identifier corresponding to the enhanced uplink feature when the enhanced uplink feature is off;
• means for detecting that a presence of the IE configured to turn on the enhanced uplink feature has changed to turn on the enhanced uplink feature;
• and
• means for transmitting a signaling message in response to the detection, wherein the transmitting the signaling message follows a withholding of the transmitting until an occurrence of a predetermined event comprising a determination that one or more uplink data packets are ready for transmission on a data channel, and wherein the signaling message comprises a request for the identifier corresponding to the enhanced uplink feature.

A user equipment (UE) configured for spreading out over time transmission from the UE of a cell update request from a transmission of a cell update request from another UE, the UE comprising:

• at least one processor;
• a memory communicatively coupled to the at least one processor;
• and
• a wireless communication interface communicatively coupled to the at least one processor, wherein the at least one processor is configured to:
• receive, while operating in a stand-by state, a broadcast message, wherein absence of an information element (IE) configured to turn on an enhanced uplink feature indicates the enhanced uplink feature is turned off;
• not keep an identifier corresponding to the enhanced uplink feature when the enhanced uplink feature is off;
• detect that a presence of the IE configured to turn on the enhanced uplink feature has changed to turn on the enhanced uplink feature;
• and
• transmit a signaling message in response to the detection, wherein the transmitting the signaling message follows a withholding of the transmitting until an occurrence of a predetermined event comprising a determination that one or more uplink data packets are ready for transmission on a data channel, and wherein the signaling message comprises a request for the identifier corresponding to the enhanced uplink feature.

A non-transitory computer-readable medium operable on a user equipment (UE) configured for spreading out over time transmission from the UE of a cell update request from a transmission of a cell update request from another UE, the non-transitory computer-readable medium comprising:

• instructions for causing a computer to receive, while operating in a stand-by state, a broadcast message, wherein absence of an information element (IE) configured to turn on an enhanced uplink feature indicates the enhanced uplink feature is turned off;
• instructions for not keeping an identifier corresponding to the enhanced uplink feature when the enhanced uplink feature is off;
• instructions for causing the computer to detect that a presence of the IE configured to turn on the enhanced uplink feature has changed to turn on the enhanced uplink feature;
• and
• instructions for causing the computer to transmit a signaling message in response to the detection, wherein the transmitting the signaling message follows a withholding of the transmitting until an occurrence of a predetermined event comprising a determination that one or more uplink data packets are ready for transmission on a data channel, and wherein the signaling message comprises a request for the identifier corresponding to the enhanced uplink feature.

A method of wireless communication operable on a user equipment (UE), the method comprising:

• receiving, while operating in a stand-by state, a broadcast message, wherein absence of an information element (IE) configured to turn on an enhanced uplink feature indicates the enhanced uplink feature is turned off;
• not keeping an identifier corresponding to the enhanced uplink feature when the enhanced uplink feature is off;
• detecting that a presence of the IE configured to turn on the enhanced uplink feature has changed to turn on the enhanced uplink feature;
• and
• transmitting a signaling message in response to the detection, wherein the transmitting the signaling message follows a withholding of the transmitting until an occurrence of a predetermined event comprising a determination that one or more uplink data packets are ready for transmission on a data channel, and wherein the signaling message comprises a request for the identifier corresponding to the enhanced uplink feature.
