Power saving features in a communication device

摘要

A method in a communication network includes receiving a data unit that includes a request to transmit an aggregate data unit to a communication device, and, in response to receiving the data unit, generating an aggregate data unit for transmission to the communication device, where the aggregate data unit includes a plurality of component data units, each having a respective media access channel (MAC) header, and a duration of the aggregate data unit is determined using a parameter negotiated with the communication device.

1. A method in a communication network, the method comprising:
negotiating a duration of time during which a communication device can receive an aggregate data unit using an add traffic stream (ADDTS) communication frame; receiving, from the communication device during a Power Save Poll (PS-Poll) mode, a trigger frame that includes i) a request to transmit the aggregate data unit to the communication device during the PS-Poll mode, and ii) an indication of the duration of time during which the communication device can receive the aggregate data unit; in response to receiving the trigger frame, generating an aggregate data unit for transmission to the communication device, wherein:
the aggregate data unit includes a plurality of component data units, each having a respective media access channel (MAC) header, andthe aggregate data unit is generated in accordance with the duration of time; and in response to receiving the trigger frame, transmitting, during the PS-Poll mode, the aggregate data unit to the communication device.
