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.

Abstract: Transmission coordination within multiple user, multiple access, and/or MIMO wireless communications. Within wireless communication systems, there can be various wireless communication devices therein that are not all compliant with a common capability set, communication protocol, communication standard, recommended practice, etc. For example, some communication systems may have some wireless communication devices characterized as ‘legacy’ wireless communication devices, and other wireless communication devices therein may be newer and compliant with newer capability sets, communication protocols, communication standards, recommended practices, etc. In such instances, coordination of transmissions among the various wireless communication devices may be made, when performing simultaneous transmissions, by ensuring that transmissions of devices on different channels is made when aligned on a common boundary of an OFDM symbol. Alternatively, such simultaneous transmissions may be made when offset by some multiple of OFDM symbol duration. When performing non-simultaneous transmissions, transmissions may be made based on channel availability.

Abstract: A device may use positioning information to increase the efficiency a wireless local area network (WLAN) scanning process. To determine the presence of WLANs within range, a device may determine its own location. For example, the device may determine its own location using a satellite-based navigation system. The device may then determine a wireless scanning strategy based on the determined location. The determination may be further based on connection parameters, such as, channel information, network capabilities, and/or other connection parameters.

Abstract: A wireless communication device (e.g., operative within a wireless local area network (WLAN)) coordinates with another wireless communication device to determine which communication parameter(s) to use in at least one FTM frame exchange. In an example of operation, the wireless communication device includes a communication interface and a processor such that the processor receives, via the communication interface, a fine timing measurement (FTM) request frame from the other wireless communication device. The FTM request frame specifies at least one preferred communication parameter for the at least one FTM frame exchange. The processor then determines, based on the FTM request frame, information related to the at least one preferred communication parameter. The wireless communication device generates and transmits a response to the FTM request frame to the other wireless communication device that confirms or overrides the at least one preferred communication parameter.
