Preamble and header bit allocation for power savings within multiple user, multiple access, and/or MIMO wireless communications
First Claim
1. A method for operating a first wireless communication device, the method comprising:
- employing a wireless transceiver for receiving a group definition from a second wireless communication device, the group definition including a group identifier and a plurality of associate identifiers corresponding to a plurality of devices of a group, wherein the first wireless communication device determines inclusion in the group by determining that an associate identifier corresponding to the first wireless communication device is included in the plurality of associate identifiers corresponding to the plurality of devices of the group, wherein a position of device specific data associated with the first wireless communication device is indicated, based on the plurality of associate identifiers included in the group definition; and
employing the wireless transceiver for receiving a multi-user packet from the second wireless communication device at a time subsequent to receiving the group definition, the multi-user packet including a PHY (physical layer) header having a group identification field (group ID field) that includes the group identifier.

Abstract
Preamble and header bit allocation for power savings within multiple user, multiple access, and/or MIMO wireless communications. Within a multi-user packet, information (e.g., partial address information) related to a recipient group of wireless communication devices (e.g., as few as one wireless communication device or any subset of a number of wireless communication devices, sometimes including all of the wireless communication devices) is emplaced within a PHY (e.g., physical layer) header of such a multi-user packet to be communicated within a multi-user (MU) environment. Such recipient indicating information can be encoded with relatively higher robustness (e.g., lower coding rates, lower ordered modulation, cyclic redundancy check (CRC), etc.) that remaining portions of the multi-user packet. Various portions of the remainder of the multi-user packet may respectively correspond to different wireless communication devices (e.g., a first field for a first wireless communication device, a second field for a second wireless communication device, etc.).
