Method and system for power saving scheduling in wireless local area networks
First Claim
1. A power saving (PS) scheduling method for communication in a wireless network, comprising the steps of:
- determining a power saving schedule of transmission opportunities for communication between a PS transmitter and at least one PS receiver over a shared channel, wherein the schedule includes corresponding durations for uplink transmissions of frames from each PS receiver to the PS transmitter;
constructing a Power Saving Aggregation Descriptor (PSAD) frame containing said schedule; and
initiating a PSAD sequence by transmitting the PSAD from the PS transmitter to each PS receiver.

Abstract
A power saving (PS) scheduling process is provided for scheduling uplink and downlink frame transmissions between a PS transmitter and at least one PS receiver using PSAD sequences in a wireless communication system. The power saving scheduling process involves determining a power saving schedule of transmission opportunities for communication between a PS transmitter and at least one PS receiver over a shared channel, wherein the schedule includes corresponding durations for uplink transmissions of frames from each PS receiver to the PS transmitter. A Power Saving Aggregation Descriptor (PSAD) frame containing said schedule is constructed. A PSAD sequence is initiated by transmitting the PSAD from the PS transmitter to each PS receiver.

47. A power saving (PS) wireless receiver, comprising:
-
a receiving module that is configured to receive a Power Saving Aggregation Descriptor (PSAD) from a PS transmitter, the PSAD including a power saving schedule of transmission opportunities for communication between the PS transmitter and at least one PS receiver over a shared channel, wherein the schedule includes corresponding durations for uplink transmissions of frames from each PS receiver to the PS transmitter; and a PSAD analyzer that is configured to analyze the schedule in the PSAD, and if the received PSAD does not specify a schedule for this receiving PS receiver, then enter the PS receiver into a power saving cycle, otherwise communicate with the PS transmitter according to a corresponding schedule in the PSAD. - View Dependent Claims (48, 49, 50, 51, 52, 53, 54, 55, 56, 57)
