Method for transmitting multi unicast information within broadcasted information

A method for transmitting a communication frame in a wireless network, wherein the information is broadcasted by using more than one modulation and coding scheme (MCS), the method comprising:

• at a base station adapted to communicate with a first plurality of mobile stations, receiving indications of bandwidth requests generated by a first mobile station, a second mobile station, and a third mobile station;
• identifying a first decoding capability which corresponds to a first MCS and is associated with at least the first mobile station;
• identifying a second decoding capability which corresponds to a second MCS and is associated with at least the second mobile station and the third mobile station;
• preparing a first bandwidth request acknowledgement message in response to the bandwidth request indications received from the first mobile station;
• preparing a second bandwidth request acknowledgement message in response to the bandwidth request indications received from the second mobile station;
• preparing a third bandwidth request acknowledgement message in response to the bandwidth request indications received from the third mobile station;
• and
• transmitting towards the first plurality of mobile stations, a communication frame which comprises aggregated multi unicast information within broadcasted information including the first bandwidth request acknowledgement message using the first MCS, the second bandwidth request acknowledgement message using the second MCS, and the third bandwidth request acknowledgment message also using the second MCS.

A method of operating a base station (BS) in a wireless network which comprises a first plurality of mobile stations (MSs), wherein said information is broadcasted by using more than one modulation and coding scheme, comprising:

• receiving bandwidth request indicators from a second plurality of MSs, the second plurality of AMSs being a subset of the first plurality of MSs;
• preparing a plurality of bandwidth request acknowledgements in response to said bandwidth requests indicators received;
• and
• transmitting to said second plurality of MSs, a communication frame which comprises aggregated multi unicast information within broadcasted information intended for the second plurality of MSs, the communication frame including the plurality of bandwidth request acknowledgements, wherein at least one of the plurality of bandwidth request acknowledgements is transmitted with a modulation and coding scheme which is different from the modulation and coding scheme which is used to transmit at least one other of the plurality of bandwidth request acknowledgements.
