Embodiment Construction

[0031] Referring now to the accompanying drawings. figure 1 is a block diagram showing a long term evolution (LTE) user plane protocol stack.

[0032] UE 110 communicates with evolved Node B (eNB) 120 and Access Gateway (aGW) 130 .

[0033] Various layers are shown in the protocol stack. A Packet Data Convergence Protocol (PDCP) layer 140 is shown on both UE 110 and aGW 130 . The PDCP layer 140 performs Internet Protocol (IP) header compression and decompression, user data encryption, user data transfer, and maintenance of a sequence number (SN) of a radio bearer.

[0034] Below the PDCP layer 140 is a radio link control protocol layer 142 that communicates with a radio link control protocol layer 142 on the eNB 120 . As will be understood, by figure 1 and 2 Communication occurs at the physical layer in the protocol stack shown in . However, RLC-PDUs from the RLC layer 142 of the UE are interpreted by the RLC layer 142 on the eNB 120 .

[0035] Below the RLC layer 142 i...

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.

Description

technical field [0001] The present disclosure relates generally to Long Term Evolution (LTE) of the Third Generation Partnership Project (3GPP), and in particular to Discontinuous Reception (DRX) of User Equipment (UE) in LTE infrastructure. Background technique [0002] In a LTE infrastructure, a UE can be in one of two Radio Resource Control (RRC) states. These states are LTE_IDLE and LTE_ACTIVE. [0003] A UE may be configured for Discontinuous Reception (DRX) in LTE_IDLE and LTE_ACTIVE states. DRX allows the UE to synchronize its listening cycle with a known network paging cycle. By synchronizing the listening cycle, the UE can turn off its radio transceiver during standby, which greatly saves battery resources. As will be understood by those skilled in the art, unless the UE is overused, significant drain on the UE's battery comes from its monitoring the paging channel and measuring the standby period of the serving cell and neighboring cells. The DRX parameters all...
