System and method for DRX control and NACK/ACK
First Claim
1. A method of receiving an acknowledgment (ACK) or negative-acknowledgment (NACK) in a device comprising:
- configuring the device for discontinuous reception (DRX) having at least one awake period and at least one sleep period, wherein a receiver of the device is on during the at least one awake period, and the receiver of the device is on for at least some portion of the at least one sleep period;
receiving, from an enhanced NodeB (eNB), a parameter indicating an extended time duration for the at least one awake period, the parameter received during a call setup of a voice over Internet Protocol (VOIP) call;
during the VOIP call, transmitting data to the eNB in an awake period;
extending the awake period by keeping the receiver on for the extended time duration after the awake period; and
receiving the ACK or NACK from the eNB during the extended time duration.

Abstract
Methods of combining semi-persistent resource allocation and dynamic resource allocation are provided. Packets, such as VoIP packets, are transmitted on the uplink and downlink using respective semi-persistent resources. For each mobile device, awake periods and sleep periods are defined. The semi-persistent resources are aligned with the awake periods so that most of the time the mobile device can turn off its wireless access radio during the sleep periods. In addition, signalling to request, and to allocate, resources for additional packets are transmitted during the awake periods, and the resources allocated for the additional packets are within the awake windows.

5. A wireless device comprising:
-
a receiver configured for discontinuous reception (DRX) having at least one awake period and at least one sleep period, wherein the receiver is on during the at least one awake period, and the receiver is on for at least some portion of the at least one sleep period; the receiver also configured to receive, from an enhanced NodeB (eNB), a parameter indicating an extended time duration for the at least one awake period, the parameter received during a call setup of a voice over Internet Protocol (VOIP) call; a transmitter configured to transmit data to the eNB in an awake period during the VOIP call; and the receiver further configured to; extend the awake period by keeping the receiver on for the extended time duration after the awake period; and receive acknowledgment (ACK) or negative-acknowledgment (NACK) information from the eNB during the extended time duration. - View Dependent Claims (6)

9. A method in a wireless device having a receiver radio, the method comprising:
-
configuring the receiver radio to have on and off periods, wherein the receiver radio is configured to monitor Layer 1 Channel Control Elements (CCEs) during the on periods, the on periods having a nominal on duration and the off periods having a nominal off duration; receiving, from an enhanced NodeB (eNB), a parameter indicating an extended time duration for the on periods, the parameter received during a call setup of a voice over Internet Protocol (VOIP) call; during the VOIP call, receiving a transmission from the eNB during an on period; and transmitting an acknowledgment (ACK) or negative-acknowledgment (NACK) corresponding to the transmission from the eNB at a time determined for ACK or NACK transmission, without regard to whether the receiver radio is otherwise configured in an off period, wherein a transmitter radio is configured to be on for the extended time duration from an end of the on period for the ACK or NACK transmission. - View Dependent Claims (10)
