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.

主权项

1. A method in a wireless network, the method comprising:
for each mobile device of a plurality of mobile devices, in order to receive from the mobile device, the wireless network:
a) receiving uplink packets from the mobile device using a semi-persistent uplink transmission resource that is aligned with awake periods defined for the mobile device;b) for each additional uplink packet or sub-packet for the mobile device: i) during one of the awake periods, receiving a request for an additional uplink transmission resource to transmit the additional uplink packet or sub-packet; ii) dynamically allocating the additional uplink transmission resource such that the additional uplink transmission resource occurs during one of the awake periods defined for the mobile device; iii) during one of the awake periods defined for the mobile device, transmitting signaling that defines the additional uplink allocation; iv) receiving the additional uplink packet or sub-packet using the additional uplink transmission resource.
