INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## 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 of 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. ## Claims ### Claim at position 1 1-6. (canceled) ### Claim 7 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. ### Claim 8 A method of transmitting 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, receiving data from the eNB in an awake period; extending the awake period by keeping a transmitter of the device on for the extended time duration after the awake period; and transmitting the ACK or NACK to the eNB during the extended time duration. ### Claim 9 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. ### Claim 10 (depends on 7) The method of claim 7, wherein the configuring for DRX further comprises: receiving a DRX configuration in a Radio Resource Control message; and configuring the device for DRX based on the DRX configuration. ### Claim 11 (depends on 8) The method of claim 8, wherein the configuring for DRX further comprises: receiving a DRX configuration in a Radio Resource Control message; and configuring the device for DRX based on the DRX configuration. ### Claim 12 (depends on 9) The wireless device of claim 9, wherein the receiver is configured to: receive a DRX configuration in a Radio Resource Control message; and configure the wireless device for DRX based on the DRX configuration.
