Method for scheduling wake/sleep cycles by a central device in a wireless network
First Claim
1. A method for scheduling wake/sleep cycles by a central device in a wireless network comprising at least one mobile device, said method comprising:
- attributing a wake/sleep cycle length to each mobile device, wherein the wake/sleep cycle length is an integer multiple of a system schedule cycle;
assigning a sleep period and a wake period within the wake/sleep cycle of each mobile device; and
arranging the wake/sleep cycle of each mobile device to avoid collision of the wake period with those of other mobile devices.

Abstract
A method for scheduling wake/sleep cycles by a central device in a wireless network is provided. The wireless network comprises at least one mobile device. The method comprises: attributing a wake/sleep cycle length to each mobile device, wherein the wake/sleep cycle length is an integer multiple of a system schedule cycle; assigning a sleep period and a wake period within the wake/sleep cycle of each mobile device; and arranging the wake/sleep cycle of each mobile device to avoid collision of the wake period with those of other mobile devices. The present invention can keep the maximum sleep cycle period of each MS to guarantee the QoS requirement and to efficiently utilize the system bandwidth.

9. A method for scheduling wake/sleep cycles of a mobile device, comprising the steps of:
-
receiving from a central station scheduling data for a sleep/wake cycle, wherein the sleep/wake cycle length is defined as an integer multiple of a system schedule cycle; waking and setting to sleep the appropriate circuits as a function of the scheduling data.
