Addressing for a multi-user packet

摘要

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.).

主权项

1. A method for operating a first wireless communication device, the method comprising:
employing a wireless transceiver for sending a group definition to 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 second wireless communication device determines inclusion in the group by determining that an associate identifier corresponding to the second 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 second wireless communication device is indicated, based on the plurality of associate identifiers included in the group definition; and employing the wireless transceiver for sending a multi-user packet to the second wireless communication device at a time subsequent to sending 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.
