1. A method comprising:
- transmitting, by a device, at least one data block comprising at least one field to one or more stations, the at least one field comprising an offset value, the offset value of the at least one field differing for each station; and
receiving, by the device, a response responsive to the at least one data block from the one or more stations in a desired order, wherein the offset value of the at least one field indicates the desired order in which the device receives the responses from each of the one or more stations.

9. A method comprising:
-
transmitting simultaneously, by a device, a schedule frame to one or more stations, the schedule frame comprising a plurality of station association identifier fields, each station association identifier field associated with a station of the one or more stations; and receiving, by the device, a response responsive to the schedule frame from the one or more stations in a desired order, wherein an additional order of the station association identifier fields indicates the desired order in which the device receives the responses from each of the one or more stations. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A device comprising:
-
a processing unit; a memory coupled to the processing unit; a transmitter, coupled to the processing unit, to transmit omni-directional a schedule frame, the schedule frame comprising a plurality of station association identifier fields, each station association identifier field associated with a station of one or more stations; and a receiver, coupled to the processing unit, to receive a response from the one or more stations in a desired order, wherein an additional order of the station association identifier fields indicates the desired order in which the device receives the response from the one or more stations. - View Dependent Claims (20)
