Method and apparatus for power management in communication system
First Claim
1. A method in a communication system for transmitting data from an access point to communication units capable of operating in a power-saving mode, the method comprising:
- assigning, by the access point, a first and a second association identifier in a message, to each of the communication units, to indicate the presence of respective buffered multicast data and unicast data respectively;
setting, by the access point, the first association identifier to indicate the corresponding communication unit to receive the buffered multicast data, the second association identifier to indicate the corresponding communication unit to receive the buffered unicast data; and
transmitting, by the access point, the message to awake the communication unit corresponding to the set first and/or second association identifier so as to transmit the buffered data thereto.

Abstract
A method and apparatus for power management in the communication system, wherein the method for transmitting data from an access point to communication units comprising: assigning, by the access point, a first and a second association identifier in a message, to each of the communication units, to indicate the presence of respective buffered multicast data and unicast data respectively; setting, by the access point, the first association identifier to indicate the corresponding communication unit to receive the buffered multicast data, the second association identifier to indicate the corresponding communication unit to receive the buffered unicast data; and transmitting, by the access point, the message to awake the communication unit corresponding to the set first and/or second association identifier so as to transmit the buffered data thereto.

6. An access point in a communication system for transmitting data to communication units capable of operating in a power-saving mode, the access point comprising:
-
a memory for buffering data to be transmitted to the communication units; and a processor for assigning a first and a second association identifier in a message, to each of the communication units, to indicate the presence of respective buffered multicast data and unicast data respectively; and
setting the first association identifier to indicate the corresponding communication unit to receive the buffered multicast data, the second association identifier to indicate the corresponding communication unit to receive the buffered unicast data; anda transmitter for transmitting the message to awake the communication unit corresponding the set first and/or second association identifier and then transmitting the buffered data thereto. - View Dependent Claims (7, 8, 9, 10)

11. A method used in a communication unit capable of operating in a power-saving mode for receiving data from an access point, the method comprising:
-
receiving a message from the access point; checking a first and a second association identifier in the message for the communication unit, wherein the first and second association identifier are assigned by the access point, to indicate the presence of buffered multicast data and unicast data respectively; and waking up to receive the multicast data and/or unicast data if the first and/or the second association identifier is set. - View Dependent Claims (12, 13)

14. A communication unit capable of operating in a power-saving mode for receiving data from an access point, the communication unit comprising:
-
a receiver for receiving data and a message from the access point; and a processor for cooperating with the receiver to check an first and second association identifier in the message for the communication unit, wherein the first and second association identifier are assigned by the access point, to indicate the presence of buffered multicast data and unicast data respectively; and wake up the communication unit to receive the multicast and/or unicast data if the first and/or second association identifier is set. - View Dependent Claims (15, 16)
