Embodiment Construction

[0045] Reference is now made to the accompanying drawings. figure 1 A block diagram showing a long term evolution (LTE) user interface protocol stack is shown.

[0046] UE 110 communicates with evolved Node B (eNB) 120 .

[0047] The layers are shown in the protocol stack. A Packet Data Convergence Protocol (PDCP) layer 140 is shown on both UE 110 and eNB 120 . The PDCP layer 140 performs Internet Protocol (IP) header compression and decompression, encryption of user data, transmission of user data, and maintenance of PDCP sequence numbers (SNs) for radio bearers.

[0048] Below the PDCP layer 140 is the Radio Link Control Protocol layer 142 , which communicates with the Radio Link Control Protocol layer 142 on the eNB 120 . As will be understood, by doing things like figure 1 and 2 Communication occurs at the physical layer in those protocol stacks shown. However, RLC-PDUs from the UE's RLC layer 142 are interpreted by the RLC layer 142 at the eNB 120 .

Abstract

Methods and apparatus for controlling discontinuous reception on a mobile device and in particular to control a short discontinuous reception timer in response to receipt of a medium access control control element. The methods and apparatus include stopping, restarting or maintaining the short discontinuous reception timer. Methods and apparatus for limiting or stopping a retransmission timer by providing user equipment with a maximum retry value for transmissions, by providing a maximum redundant version value, or by providing a medium access control control element to stop or prevent the start of a retransmission timer.

Description

technical field [0001] The present disclosure relates to Long Term Evolution (E-UTRA) of the 3rd Generation Partnership Project (3GPP), and in particular to Discontinuous Reception (DRX) for User Equipments (UEs) in E-UTRA infrastructure. Background technique [0002] In a Long Term Evolution infrastructure, a UE can be in one of two Radio Resource Control (RRC) states. These two states are LTE_IDLE and LTE_ACTIVE. [0003] The UE may be configured for Discontinuous Reception (DRX) in LTE_IDLE and LTE_ACTIVE states. DRX allows the UE to synchronize its listening period with the network's known paging cycle. By synchronizing the listening period with the time of acceptable transmissions from the network, the UE can turn off the radio transceiver when the network is not scheduling transmissions, thereby greatly saving battery resources. As understood by those skilled in the art, if the UE is not heavily used, a significant drain on the UE's battery comes from the standby p...
