Abstract:
A wireless communication device that is receiving a frame may determine whether the frame is an Up-Link Multi-User (UL MU) frame, receive the frame by performing a first procedure when the frame is determined to be the UL MU frame, and receive the frame by performing a second procedure when the frame is not determined to be the UL MU frame. Performing the first procedure may include performing a comparison of contents of a Legacy Signal (L-SIG) field of the frame to expected contents of the L-SIG field, performing a comparison of contents of a Signal A (SIG-A) field of the frame to expected contents of the SIG-A field, or both. The SIG-A field may be a High Efficiency SIG-A (HE-SIG-A) field.

Claim (Index 1):
A wireless communication device comprising:\n a transmitter circuit; and a receiver circuit, wherein the wireless communication device is configured to: transmit, using the transmitter circuit, a first frame that solicits an Up-Link Multi-User (UL MU) frame; determine whether a second frame is the UL MU frame solicited by the first frame; receive, using the receiver circuit, the second frame by performing a first procedure in response to determining that the second frame is the solicited UL MU frame; and receive, using the receiver circuit, the second frame by performing a second procedure in response to determining that the second frame is not the solicited UL MU frame, wherein performing the first procedure includes performing a comparison of contents of a Legacy Signal (L-SIG) field of the second frame to expected contents of the L-SIG field of the second frame, performing a comparison of contents of a Signal A (SIG-A) field of the second frame to expected contents of the SIG-A field of the second frame, or both, and wherein performing the comparison of the contents of the SIG-A field to the expected contents of the SIG-A field includes one or more selected from the group consisting of:\n comparing a value of a bandwidth field of the SIG-A field indicating an operating bandwidth to an expected value of the bandwidth field, \n comparing a value of a Spatial Reuse field of the SIG-A field indicating a Clear Channel Assessment (CCA) level, an interference level accepted, or a transmission (TX) power to an expected value of the Spatial Reuse field, \n comparing a value of a Space Time Block Coding (STBC) field of the SIG-A field indicating whether the second frame applies STBC to an expected value of the STBC field, \n comparing a value of a Group Identifier (ID) field of the SIG-A field indicating a group which includes a station related to the second frame to an expected value of the Group ID field, \n comparing a value of a Number of Space-Time Streams (NSTS) field of the SIG-A field indicating a number of space-time streams to an expected value of the NSTS field, \n comparing a value of a Coding field of the SIG-A field indicating a coding type of the second frame to an expected value of the Coding field, \n comparing a value of a Modulation and Coding Scheme (MCS) field of the SIG-A field indicating a MCS of the second frame to an expected value of the MCS field, \n comparing a value of a beamforming field of the SIG-A field indicating if the second frame applies beamforming to an expected value of the beamforming field, \n comparing a value of a Transmission Opportunity (TXOP) Duration field of the SIG-A field indicating the remaining time in the current TXOP to an expected value of the TXOP Duration field, and \n comparing a value of a Guard Interval (GI) field of the SIG-A field indicting a type of a length of a Cyclic Prefix (CP) of the second frame to an expected value of the GI field.
