    摘要： Methods and apparatuses for providing CQI feedback with common code rate to a transmitter station are described herein. In one implementation, the methods may include a receiver station that is communicatively linked to a transmitter station via k spatial channels transmitting a first CQI to the transmitter station that indicates a modulation level for use by the transmitter station to transmit (i.e., to configure for transmission) a first of k streams of signals to be transmitted to the receiver station. The first CQI may further include a common code rate to be used by the transmitter station for transmitting the first of the k streams of signals as well as for transmitting the rest of the k−1 additional streams of signals to the receiver station. The receiver station may further transmit to the transmitter station k−1 additional CQIs to indicate to the transmitter station the k−1 modulation levels to be used by the transmitter station for transmitting the k−1 additional streams of signals to the receiver station.

    摘要： Example systems, methods, and devices for efficient indication of bandwidth and stream allocation are discussed. In one embodiment, a method for indication of bandwidth allocation in a wireless network can include partitioning, by a network device, a bandwidth of a wireless signal into a plurality of subband units, assigning one or more switch bits between adjacent subband units, and allocating one or more modified subband units to one or more users of the network. In another embodiment, a method for stream allocation can include partitioning, by a network device, a spatial stream of a wireless signal into a plurality of spatial streams, assigning one or more switch bits between adjacent spatial streams, and allocating one or more modified spatial streams to one or more users of the network. Certain methods, apparatus, and systems described herein can be applied to 802.11ax or any other wireless standard.

    摘要： A method and a system that multiplies a beamforming matrix by a unitary matrix that does not change the subspace of the beamforming matrix for form a converted matrix having a lower left triangle of zeros. A first column vector having a fewest number of elements of the converted matrix is quantized using a codebook and represented by a first codebook index. A Householder matrix is determined from the quantized first column vector and the converted matrix is multiplied by the Householder matrix. Quantizing, determining a Householder matrix from further column vectors of the converted matrix using a codebook and representing each respective column vector by further corresponding codebook index, and multiplying the converted matrix on the left by the determined Householder matrix for each respective column vector are recursively repeated. The first codebook index and further codebook indices are transmitted to a remote station for use in beamforming.
