Transmission coordination within multiple user, multiple access, and/or MIMO wireless communications
First Claim
1. A wireless communication device comprising:
- a communication interface; and
processing circuitry, at least one of the communication interface or the processing circuitry configured to;
transmit a first signal to at least one other wireless communication device via a first subset of orthogonal frequency division multiplexing (OFDM) sub-carriers at or during a first time and at or during a second time that is subsequent to and adjacently follows the first time; and
transmit a second signal to the at least one other wireless communication device or at least one additional wireless communication device via a second subset of OFDM sub-carriers at or during the second time, wherein transmission of the second signal via the second subset of OFDM sub-carriers begins after the first time, wherein the second signal is offset to the first signal by an integer multiple of OFDM symbol durations, wherein the integer multiple is greater than or equal to one.

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.
