1. A method for use by a subscriber unit to select a time to receive a transmission from a wireless local area network access point using a shared wireless communication resource, comprising:
- receiving a beacon transmission from the access point comprising first information that corresponds to times when other subscriber units are proposing to utilize the shared wireless communication resource;
using the first information to select a particular time to receive data from the access point using the shared wireless communication resource.

Abstract
An access point utilizes information (11) as provided by various subscriber units to provide a message (12) (as included with, for example, a beacon transmission) that reflects near term likely utilization of a shared communication resource. A subscriber unit (20) can then utilize that information to schedule its own monitoring activity. This, in turn, permits the subscriber unit to similarly schedule power saving activities to accommodate this reception schedule.

8. A method for use by a wireless local area network access point to facilitate reception of transmissions from the access point by subscriber units using a shared wireless communication resource, comprising:
-
receiving transmissions from a plurality of subscriber units, wherein the transmissions include information that identifies proposed times when each of the plurality of subscriber units proposes to utilize the shared wireless communication resource;
including schedule information that corresponds to at least a part of the information in a beacon transmission to the subscriber units, such that at least one of the subscriber units can utilize the schedule information to schedule a sleep mode of operation that is consistent with data reception at a selected particular time. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method for permitting subscriber units using a shared wireless communication resource to utilize a wireless local area network access point, comprising:
-
at various of the subscriber units;
transmitting to the access point information that corresponds to proposed transmission times for at least some of the various of the subscriber units;
at the access point;
using the information to form a message;
transmitting the message in a beacon transmission to the subscriber units;
at at least one of the subscriber units;
receiving the beacon transmission;
using the message to select a first particular time at which to shift from a sleep mode of operation to an active mode of operation. - View Dependent Claims (17, 18, 19, 20, 21)

22. A subscriber unit for use with a wireless local area network access point using a shared wireless communication resource, comprising:
-
a shared wireless communication resource compatible transceiver;
a controller having at least an active mode of operation and a sleep mode of operation and being operably coupled to the transceiver;
a memory operably coupled to the controller having, at least from time to time, stored therein;
a plurality of proposed times at which other subscriber units have proposed to utilize the shared wireless communication resource;
a first scheduled time at which the controller will shift from the sleep mode of operation to the active mode of operation;
a second scheduled time at which the controller will cause the transceiver to receive data as transmitted by the access point. - View Dependent Claims (23, 24, 25)
