Distributed signal field for communications within multiple user, multiple access, and/or MIMO wireless communications

摘要

Distributed signal field for communications within multiple user, multiple access, and/or MIMO wireless communications. In accordance with wireless communications, a signal (SIG) field employed within such packets is distributed or partitioned into at least two separate signal fields (e.g., SIG A and SIG B) that are located in different portions of the packet. A first of the SIG fields includes information that may be processed and decoded by all wireless communication devices, and a second of the SIG fields includes information that is specific to one or more particular wireless communication devices (e.g., a specific wireless communication device or a specific subset of the wireless communication devices).;The precise locations of the at least first and second SIG fields within a packet may be varied, including placing a second of the SIG fields (e.g., including user-specific information) adjacent to and preceding a data field in the packet.

主权项

1. A wireless communication device comprising:
a processor configured to:
generate a packet that includes a group identification field (GroupID);set a plurality of bits within the GroupID to a first value to indicate the packet is a single user (SU) packet or set the plurality of bits within the GroupID to a second value to indicate the packet is a multiple user (MU) packet; andtransmit the packet to at least one other wireless communication device.
