摘要： Modulation code set (MCS) and LDPC (Low Density Parity Check) coding within multiple user, multiple access, and/or MIMO wireless communications. Selective operation in accordance with different operational modes is performed. Operation within a first mode may correspond to that which is in full compliance with a given protocol, standard, and/or recommended practice, while operation within a second mode may correspond to that which provides additional/augmented capability and/or functionality with respect to that protocol, standard, and/or recommended practice. Operational modes selectivity may be made between proprietary and non-proprietary modes of operation. All available modulation coding sets (MCSs) may be in employed by providing such multi-mode operation. When operating within one of the operational modes (e.g., proprietary), a signal is generated to include an integer number of data bits per orthogonal frequency division multiplexing (OFDM) symbol using any desired operation (e.g., floor, ceiling, rounding, etc.).

摘要： Preamble for use within single user, multiple user, multiple access, and/or MIMO wireless communications. A selected preamble type is employed for use in generating a signal to be transmitted from one communication device to at least one other communication device. Depending upon a desired operational mode, as few as one preamble type, or two or more preamble types may be associated with a given operational mode. When operating in accordance with a given operational mode, a preamble type is selected from available preamble types of an operational mode. A preferred implementation may include two respective preamble types such that one preamble type is used for single user (SU) operation with transmit beamforming weights applied at the beginning of the packet or for open loop SU transmissions only, while the other preamble type, having an multiple user (MU) characteristic, is used for both SU beamforming and MU operations.

摘要： A method and system for a double search algorithm of user group selection for multiuser MIMO downlink transmission are provided. The use of optimal brute-force user group selection may require high computational expense. A first search operation may be based on a first user having a channel gain greater than that of other users, while a second search operation may be based on a second user having a channel gain greater than that of the remaining users. A maximized system capacity may be determined based on the maximized system capacities determined in the first and second search loop. A receiver pair associated with the maximized system capacity may be selected as the user group. The double search algorithm may reduce the computational complexity while achieving performances that may exceed the TDMA scheme and be similar to that of systems with ideal CSI at the transmitter.

摘要： Phase rotation for preambles within multiple user, multiple access, and/or MIMO wireless communications. An appropriately designed phase rotation vector and/or appropriately designed cyclic shift delays (CSDs) are applied to respective sub-band components of the preamble. With appropriately designed CSDs, certain fields within the preamble are not modified. For example, a legacy short training field (L-STF) of the preamble is not changed when using appropriately designed CSDs. The respective CSDs may be implemented as integer multiples of a common CSD (e.g., 0×CSD, 1×CSD, 2×CSD, etc. such that one of the values of such a CSD vector may be zero [0], another may be the common CSD itself, etc.). Also, by employing an appropriately designed phase rotation vector and integer multiples of a CSD to a preamble, the respective peak to average power ratio (PAPR) between different respective fields within the preamble may be minimized.
