Distributed signal field for communications within multiple user, multiple access, and/or MIMO wireless communications
First Claim
1. A wireless communication device comprising:
- a processor configured to;
generate a packet that includes a first signal (SIG) field, a second SIG field, and at least one other field located between the first and second SIG fields;
set at least one bit within the first SIG field to a first value to indicate the packet is a single user (SU) packet or set the at least one bit within the first SIG field to a second value to indicate the packet is a multiple user (MU) packet, wherein when the packet is a MU packet;
the first SIG field includes information for use by both first and second other wireless communication devices to process a first other field in the MU packet; and
the second SIG field includes information for use by one or both of the first and second other wireless communication devices to process a second other field in the MU packet; and
a communication interface configured to transmit the packet.

Abstract
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.

9. A wireless communication device comprising:
-
a processor configured to; generate a packet that includes a first signal (SIG) field, a second SIG field, and at least one other field located between the first and second SIG fields, wherein the packet includes a first short training field (STF), followed by a first long training field (LTF), followed by the first SIG field, followed by a second STF, followed by a second LTF, followed by the second SIG field, followed by a data field; set at least one bit within the first SIG field to a first value to indicate the packet is a single user (SU) packet or set the at least one bit within the first SIG field to a second value to indicate the packet is a multiple user (MU) packet, wherein when the packet is a MU packet; the first SIG field includes information for use by both first and second other wireless communication devices to process a first other field in the MU packet; and the second SIG field includes information for use by one or both of the first and second other wireless communication devices to process a second other field in the MU packet; and a communication interface configured to transmit the packet such that the first SIG field of the packet is transmitted using omni-directional transmission and the second SIG field of the packet is transmitted using beamforming transmission. - View Dependent Claims (10, 11, 12, 13)

14. A method for execution by a wireless communication device, the method comprising:
-
generating a packet that includes a first signal (SIG) field, a second SIG field, and at least one other field located between the first and second SIG fields; setting at least one bit within the first SIG field to a first value to indicate the packet is a single user (SU) packet or set the at least one bit within the first SIG field to a second value to indicate the packet is a multiple user (MU) packet, wherein when the packet is a MU packet; the first SIG field includes information for use by both first and second other wireless communication devices to process a first other field in the MU packet; and the second SIG field includes information for use by one or both of the first and second other wireless communication devices to process a second other field in the MU packet; and transmitting the packet via a communication interface of the wireless communication device. - View Dependent Claims (15, 16, 17, 18, 19, 20)
