System and Method for Semi-Persistent and Dynamic Scheduling and Discontinuous Reception Control

摘要

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.

1. A method in a wireless network, the method comprising:
transmitting, by the network, downlink packets to a mobile device using a periodic semi-persistent downlink transmission resource that is aligned with discontinuous reception (DRX) awake periods, wherein the semi-persistent downlink transmission resource is scheduled using semi-persistent scheduling; during one of the awake periods defined for the mobile device, transmitting, by the network, signaling that defines an additional downlink transmission resource to transmit an additional packet or sub-packet, the additional resource being allocated to occur within one of the awake periods, wherein the additional transmission resource is scheduled using dynamic scheduling; during one of the awake periods defined for the mobile device, transmitting the additional downlink packet using the additional downlink resource; de-allocating the semi-persistent downlink transmission resource.
