Abstract
A method of DRX signaling in a long-term evolution infrastructure between an evolved node B (eNB) and user equipment (UE), the method having the steps of providing a DRX value in a header of a medium access control protocol data unit (MAC-PDU); acknowledging the MAC-PDU; and activating, deactivating or reconfiguring DRX based on the provided DRX value.
Claims33
A method of DRX signaling in a long-term evolution infrastructure between an evolved node B (eNB) and user equipment (UE), the method comprising the steps of
- providing a DRX value in a header of a medium access control protocol data unit (MAC-PDU);
- acknowledging the MAC-PDU;
- and
- activating, deactivating or reconfiguring DRX based on the provided DRX value.
A method of leveraging application level traffic characteristics to improve battery life or for signaling traffic characteristics to improve system response time of user equipment (UE) communicating with an evolved Node B (eNB) comprising the steps of:
- requesting, from the UE, a discontinuous reception (DRX) based on application traffic characteristics of the UE;
- receiving the request from the UE at the eNB;
- and
- granting, negotiating an alternative period or rejecting the request at the eNB.
A method for improved measurement accuracy during discontinuous reception (DRX) on user equipment (UE) comprising the steps of:
- checking whether a channel quality of a serving cell is lower than a first threshold for a predetermined time period;
- and
- if yes, shortening the measurement cycle to have a shorter measurement cycle than the DRX cycle.
A method of handling missed handover opportunities based on discontinuous reception (DRX) in user equipment (UE) comprising the steps of:
- checking whether a channel quality and/or signal strength of a serving cell is less than the channel quality and/or signal strength of a neighboring cell by a threshold value for a certain time duration;
- and
- if yes, connecting to the neighboring cell.
An evolved node B (eNB) operating in a long-term evolution infrastructure, the ENB being characterized by means for:
- providing a DRX value in a header of a medium access control protocol data unit (MAC-PDU);
- and
- activating or deactivating DRX based on the DRX value.
A user equipment (UE) operating in a long-term evolution (LTE) infrastructure, the UE being characterized by means for:
- receiving a DRX value in a header of a medium access control protocol data unit (MAC-PDU)
- acknowledging the MAC-PDU;
- and
- activating deactivating, or reconfiguring DRX based on the DRX value.
