Additionally or alternatively, one or more functionalities of message processors 128 and/or 158 may be implemented by logic, which may be executed by a machine and/or one or more processors, e.g., as described below.
In some demonstrative embodiments, devices 102 and/or 140 may be configured to operate in accordance with one or more Specifications, for example, including, one or more IEEE 802.11 Specifications, e.g., an IEEE 802.11ad Specification, an IEEE 802.11REVmc Specification, an IEEE 802.11ay Specification, and/or any other specification and/or protocol.
Some demonstrative embodiments may be implemented, for example, as part of a new standard in an mmWave band, e.g., a 60 GHz frequency band or any other directional band, for example, as an evolution of an IEEE 802.11ad Specification.
In some demonstrative embodiments, devices 102 and/or 140 may be configured according to one or more standards, for example, in accordance with an IEEE 802.11ay Standard, which may be, for example, configured to enhance the efficiency and/or performance of an IEEE 802.11ad Specification, which may be configured to provide Wi-Fi connectivity in a 60 GHz band.
In some demonstrative embodiments, devices 102 and/or 140 may implement a communication scheme, which may include Physical layer (PHY) and/or Media Access Control (MAC) layer schemes, for example, to support one or more applications, and/or increased transmission data rates, e.g., data rates of up to 30 Gbps, or any other data rate.
In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement one or more channel bonding mechanisms, which may, for example, support communication over bonded channels.
In some demonstrative embodiments, the channel bonding mechanisms may include, for example, a mechanism and/or an operation whereby two or more channels can be combined, e.g., for a higher bandwidth of packet transmission, for example, to enable achieving higher data rates, e.g., when compared to transmissions over a single channel. Some demonstrative embodiments are described herein with respect to communication over a bonded channel, however other embodiments may be implemented with respect to communications over a channel, e.g., a “wide” channel, including or formed by two or more channels, for example, an aggregated channel including an aggregation of two or more channels.
In some demonstrative embodiments, device 102 and/or device 140 may be configured to implement one or more channel bonding mechanisms, which may, for example, support an increased channel bandwidth, for example, a channel BW of 4.32 GHz, a channel BW of 6.48 GHz, and/or any other additional or alternative channel BW.
In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement, for example, in addition to, or instead of, one or more MIMO and/or channel bonding techniques, a Physical layer (PHY) feature of a Low-Density Parity-Check (LDPC) code, for example, with an extended LDPC codeword length. For example, implementing an LDPC code with a longer codeword may provide better performance than an LDPC code with a shorter codeword length, e.g., under an assumption of the same encoding rate.
In some demonstrative embodiments, an LDPC code may use an extended codeword length, for example, a codeword length of 1344 bits, which may be two times longer than a codeword length (“legacy codeword length”), e.g., a codeword length of 672 bits, which may be utilized according to an IEEE 802.11ad Specification.
For example, an approach of an LDPC code with the extended codeword length, e.g., as may be adopted by a future IEEE 802.11ay Specification, may be implemented, for example, using lifting matrices to produce an LDPC check parity matrix with extended dimensions, e.g., as described below.
In some demonstrative embodiments, defining matrices for one or more encoding rates, for example, for the encoding rates 1/2, 5/8, 3/4, and 13/16, may not be enough. For example, such an approach may not cover, and/or may not be compatible with, an encoding rate of 7/8, which may be compatible with a legacy codeword length, e.g., in accordance with an IEEE 802.11ad Specification.
For example, the coding rate of 7/8, e.g., in compliance with an IEEE 802.11ad Specification development, utilizes an LDPC codeword length of 624 bits. The introduction of this encoding rate and corresponding Modulation and Coding Schemes (MCSs) may allow, for example, achieving a more efficient implementation of a link adaptation algorithm and, accordingly, may improve or optimize overall system performance.
For example, a code with the code rate of 7/8 may be obtained by application of a puncturing procedure to an LDPC code (“initial LDPC code”), for example, with a codeword length of 672 bits and an encoding rate of 13/16, e.g., as described below.
In some demonstrative embodiments, the puncturing procedure may puncture the first 48 parity bits of the initial LDPC code, for example, to achieve a required ratio of a systematic data part equal to 546 bits as for the initial 13/16 LDPC code, and a reduced (punctured) codeword length of 624 bits.
In some demonstrative embodiments, introduction of the new encoding rate of 7/8, e.g., based on the puncturing procedure, may provide technical benefits, for example, by solving a technical problem, for example, by allowing to even maintain a source LDPC code unchanged, and/or limiting the implementation effort and hardware complexity.
In some demonstrative embodiments, devices 102 and/or 140 may be configured to encode, generate, transmit, receive and/or process transmissions utilizing an extended LDPC codeword, e.g., having an extended codeword length of 1248 bits or any other extended codeword length, corresponding to the encoding rate of 7/8, e.g., as described below.
In some demonstrative embodiments, the LDPC code with encoding rate 7/8 and codeword length of 1248 bits may provide technical benefits, for example, when implemented, for example, together with QPSK, 16QAM, 64QAM, and 256QAM, SQPSK modulations, and/or any other additional or alternative modulation schemes, e.g., as described below.
In some demonstrative embodiments, the LDPC code with encoding rate 7/8 and codeword length of 1248 bits may provide technical benefits, for example, when implemented, for example, with channel bonding techniques, for example, 2×, 3×, and/or 4× channel bonding, and/or any other channel bonding factor, e.g., as described below.
In some demonstrative embodiments, the LDPC code with encoding rate 7/8 and codeword length of 1248 bits may provide technical benefits, for example, when implemented, for example, with channel aggregation techniques, for example, 2×, 3×, 4× channel aggregation, and/or any other channel aggregation factor, e.g., as described below.
In some demonstrative embodiments, the LDPC code with encoding rate 7/8 and codeword length of 1248 bits may provide technical benefits, for example, when implemented, for example, for a Single User MIMO (SU-MIMO) transmission, e.g., as described below.
In some demonstrative embodiments, the LDPC code with encoding rate 7/8 and codeword length of 1248 bits may provide technical benefits, for example, when implemented, for example, for a Multi User MIMO (MU-MIMO) transmission, e.g., as described below.
In some demonstrative embodiments, the extended codeword length of 1248 bits for the encoding rate of 7/8 may be obtained, for example, based on a puncturing procedure, e.g., as described below.
For example, an initial LDPC code with a codeword length of 1344 bits and an encoding rate of 13/16 may be used to determine a plurality of parity bits, e.g., as described below. For example, the first 96 bits of the parity bits may be punctured, for example, to obtain the required length of 1248 bits. Accordingly, this procedure may allow achieving the encoding rate of 7/8, for example, with a systematic data part length of 1092 bits, and a codeword length of 1248 bits.
In some demonstrative embodiments, the puncturing technique described herein may allow achieving a competitive performance for codes with an encoding rate of 7/8, for example, while preserving a limited implementation complexity required to support this encoding rate.

In some demonstrative embodiments, encoder 129 may be configured to encode a plurality of data bits into a plurality of codewords according to an LDPC code having an encoding rate of 7/8 and a codeword length of 1248 bits, e.g., as described below.
In some demonstrative embodiments, a codeword of the plurality of codewords may include 1092 data bits and 156 parity bits, e.g., as described below. In other embodiments, the codeword may include any other number of data bits, and/or any other number of parity bits.
In some demonstrative embodiments, encoder 129 may be configured to determine the 156 parity bits, for example, based on the 1092 data bits, e.g., as described below.
In some demonstrative embodiments, encoder 129 may be configured to determine a set of parity bits, for example, by applying a code matrix to the 1092 data bits, e.g., as described below.
In one example, encoder 129 may be configured to encode 1092 systematic data bits, for example, by applying an LDPC lifting matrix, e.g., an LDPC lifting matrix configured for a codeword length of 1344 bits, e.g., as described below.
In some demonstrative embodiments, the set of parity bits may include more than 156 bits, e.g., as described below.
In some demonstrative embodiments, the set of parity bits may include 252 parity bits, e.g., as described below. In other embodiments, the set of parity bits may include any other number of parity bits.
In some demonstrative embodiments, encoder 129 may be configured to generate the codeword, for example, by appending the 156 bits of the set of parity bits to the 1092 data bits, e.g., as described below.
In some demonstrative embodiments, the 1092 data bits may include a sequence of bits denoted {S0, S1, . . . , S1091}, and encoder 129 may be configured to determine the set of 252 parity bits corresponding to the 1092 data bits to include a sequence of bits denoted {p0, p1, p2, . . . , p251}, and to generate the codeword to include a sequence of the bits {S0, S1, . . . , S1091, p96, p97, . . . , p251}, e.g., as described below.
In some demonstrative embodiments, encoder 129 may be configured to produce the codeword, for example, by discarding a first group of parity bits, e.g., the parity bits p0, p1, . . . , p95, and to append the remaining parity bits, e.g., the parity bits p96, p97, . . . , p251, to the 1092 input systematic data bits to create an LDPC codeword, e.g., as described below.
In some demonstrative embodiments, an LDPC code may be defined for an encoding rate of 7/8 with an extended codeword length, for example, an extended codeword length of 1248 bits, which may be implemented by a PHY layer, for example, in accordance with a future IEEE 802.11ay Specification, e.g., as described below.
In some demonstrative embodiments, the LDPC code with the encoding rate of 7/8 and the extended codeword length, e.g., of 1248 bits, may be defined, for example, based on an LDPC code (“Initial LDPC code”) with an encoding rate of 13/16 and a codeword length of 672 bits, which, in turn, may be defined, for example, in accordance with an IEEE 802.11ad Specification, e.g., as described below.
For example, the LDPC code with the encoding rate of 13/16 and the codeword length of 672 bits may be defined, for example, by a parity check matrix (“code matrix”), e.g., as follows:
29 30 0 8 33 22 17 4 27 28 20 27 24 23 37 31 18 23 11 21 6 20 32 9 12 29 10 0 13 25 22 4 34 31 3 14 15 4 2 14 18 13 13 22 24
In some demonstrative embodiments, the parity check matrix of Table 1 may include 126 rows and 672 columns.
In some demonstrative embodiments, an element of the parity check matrix of Table 1 may include a matrix of a size Z×Z.
In one example, each nonblank element i in the Table 1 may be a cyclic permutation matrix Pi of a size Z×Z, and blank entries in Table 1 may represent a zero matrix of size Z×Z.
For example, the value of Z may be equal to 42, and the matrix Pi may be obtained from a Z×Z identity matrix, for example, by cyclically shifting the columns to the right by i elements. The matrix P0 may be the Z×Z identity matrix. An empty location may denote a null submatrix of size Z×Z.
In some demonstrative embodiments, an LDPC codeword of length of 1344 bits may be defined, for example, by extending the parity check matrix, e.g., to an extended parity check matrix, denoted H, for example, using on one or more lifting matrices, e.g., as described below.
In some demonstrative embodiments, a lifting matrix may be applied to the code matrix to generate a larger matrix, for example, the matrix H, e.g., as described below.
In some demonstrative embodiments, a ‘0’ value in the lifting matrix may act on the Z×Z cyclic-permutation matrix Pi in the code matrix, e.g., at the same location, to create a 2Z×2Z matrix, e.g., as follows:
i - 1 - 1 i
In some demonstrative embodiments, a value of ‘1’ in the lifting matrix may act on the Z×Z cyclic-permutation matrix Pi in the code matrix, e.g., at the same location, to create a 2Z×2Z matrix, e.g., as follows:
- 1 I i - 1
In some demonstrative embodiments, a value of ‘−1’ in the lifting matrix may act on the Z×Z zero matrix in the code matrix to create a 2Z×2Z zero matrix.
In some demonstrative embodiments, an LDPC code with a length of 1344 bits may be generated, for example, by applying the following lifting matrix to the rate 13/16 LDPC code matrix of Table 1:
1 0 1 1 1 1 0 0 1 1 0 1 1 0 −1 −1 0 0 0 0 0 1 0 0 0 0 0 1 1 1 0 −1 1 0 1 1 0 1 0 1 0 0 1 0 1 0 0 0

In some demonstrative embodiments, encoder 129 may be configured to discard a first group of the parity bits, e.g., the parity bits numbered from 0 to 95, e.g., the parity bits p0, p1, . . . , p95.
In some demonstrative embodiments, encoder 129 may be configured to append the remaining parity bits, e.g., the parity bits p96, p97, . . . , p251, to the input systematic data bits to create an LDPC codeword, e.g., as described above.
In some demonstrative embodiments, encoder 129 may be configured to generate the LDPC code, for example, according to an encoding procedure to satisfy one or more criteria with respect to a matrix H corresponding to the LDPC codeword with length 1344, e.g., as described below.
In some demonstrative embodiments, encoder 129 may be configured to determine the 252 parity bits of the LDPC code to satisfy the following linear system of equations in matrix form:
H*C=0 (1)
wherein H denotes a bit matrix of size 252 by 1344, C denotes a column bit vector of size 1344 by 1, and 0 denotes an all zero bit vector of size 252 by 1.
In some demonstrative embodiments, the bit vector C may include systematic and parity parts, e.g., the following data bits:
C={S0, S1, . . . , S1091, p0, p1, . . . , p251}T (2)
In some demonstrative embodiments, a required rate of 7/8 may be obtained, for example, by discarding the first 96 parity bits, for example, to produce the following codeword vector:
C˜={S0, S1, . . . , S1091, p96, p97, . . . , p251}T (3)
Accordingly, the puncturing procedure may define a new code with an effective rate of 7/8.
In some demonstrative embodiments, the linear Equation System 1 may be resolved, for example, by applying a Gauss or Gauss-Jordan elimination, and/or any other algorithm and/or calculation.
