Smart meter media access control (MAC) for single user, multiple user, multiple access, and/or MIMO wireless communications. Different types of wireless communication devices may be implemented within various wireless communication systems. Some of these devices may be implemented to communicate sensing and/or measurement to one or more other devices. For example, certain devices may be implemented to perform monitoring associated with any of a number of services provided by service providers (e.g., electricity, natural gas, water, Internet access, telephone service, and/or any other service). In accordance with such sensing and/or measurement related applications, a given device need not necessarily be awake or at a fully operative state at all times. Appropriate coordination, scheduling, communication medium access, etc. among potentially many implemented devices ensures effective communication and gathering of such sensing and/or measurement related data (e.g., using one or more service period (SP) announcements, various communication medium access options, etc.). |

1. A wireless communication device comprising:
a communication interface; and a processor, at least one of the processor or the communication interface configured to:
receive a transmission from another wireless communication device, wherein the transmission includes sensor or measurement related data;generate, in response to the transmission, an acknowledgement (ACK) that includes timestamp information that corresponds to a first clock reference maintained by the wireless communication device, wherein the timestamp information that corresponds to the first clock reference maintained by the wireless communication device includes a subset of timing synchronization function (TSF) bits of a TSF maintained by the wireless communication device; andtransmit the ACK to the another wireless communication device for use by the another wireless communication device to update or correct a second clock reference maintained by the another wireless communication device to maintain synchronization of the second clock reference to the first clock reference based on the timestamp information included within the ACK. |
