1. An apparatus comprising:
- a wireless communications device comprising;
a modulator; and
a demodulator, wherein the demodulator is to;
receive a wireless communication containing multiple data units and formatted with a multi-receiver aggregation protocol;
read a sub-header in the wireless communication to identify one or more particular segments identifying consecutive data units in the wireless communication that are addressed to the wireless communications device;
read, within the one or more particular segments, information elements each indicating respective information associated with a sub-group of one or more data units of the consecutive data units that have the same characteristics, wherein the respective information comprises a common modulation/coding rate, a common length, and a count of the one or more data units in the sub-group for receipt by the wireless communications device;
receive the identified consecutive data units, using the respective common modulation/coding rates, the respective common lengths, and the respective counts; and
not receive at least a portion of data units not identified by the one or more particular segments.

Abstract
When using a multi-receiver aggregation protocol in a wireless communications network, a sub-header may be used to identify groups of data units that share common parameters, such as destination addresses, acknowledgement modes, modulation/coding rates, lengths, etc. The layout of this sub-header may permit each receiving device to identify the portion of the aggregated payload that is addressed to that receiving device, where that portion is located, how long that portion is, and how to demodulate it. In addition, by controlling the selection and timing of various acknowledgement modes used by the mobile stations, a base station may improve overall network efficiency and throughput.

7. A method comprising:
-
receiving, by a wireless communications device, a wireless communication containing multiple data units and formatted with a multi-receiver aggregation protocol; reading, by the wireless communications device, a sub-header in the wireless communication to identify one or more particular segments identifying consecutive data units in the wireless communication that are addressed to the wireless communications device; reading, by the wireless communications device within the one or more particular segments, information elements each indicating respective information associated with a sub-group of one or more data units of the consecutive data units that have the same characteristics, wherein the respective information comprises a common modulation/coding rate, a common length, and a count of the one or more data units in the sub-group for receipt by the wireless communications device; receiving, by the wireless communications device, the identified consecutive data units, using the respective common modulation/coding rates, the respective common lengths, and the respective counts; and not receiving, by the wireless communications device, at least a portion of data units not identified by the one or more particular segments. - View Dependent Claims (8, 9, 10, 11, 12)

13. A system comprising:
-
at least one radio; at least one antenna; at least one memory; and at least one processor, wherein the at least one processor is to; receive a wireless communication containing multiple data units and formatted with a multi-receiver aggregation protocol; read a sub-header in the wireless communication to identify one or more particular segments identifying consecutive data units in the wireless communication that are addressed to the system; read, within the one or more particular segments, information elements each indicating respective information associated with a sub-group of one or more data units of the consecutive data units that have the same characteristics, wherein the respective information comprises a common modulation/coding rate, a common length, and a count of the one or more data units in the sub-group for receipt by the system; receive the identified consecutive data units, using the respective common modulation/coding rates, the respective common lengths, and the respective counts; and not receive at least a portion of data units not identified by the one or more particular segments. - View Dependent Claims (14, 15, 16, 17, 18)
