Abstract
A method of transmission of a set of I bits of information stream is described, in which said method comprises: selecting, from a pool of at least 2I matrices, a matrix to uniquely represent the set of I bits of information stream, wherein each matrix of the pool is a set of M vectors, and each vector is of length D; and transmitting a resource block across M transmit antennas, wherein respective vectors of the M vectors are transmitted on respective transmit antennas of the M transmit antennas. The transmitting comprises mapping respective entries of the respective vectors to respective resource elements of the resource block.

A method of transmission of a set of I bits of information stream, comprising:
- selecting, from a pool of at least 2I matrices, a matrix to uniquely represent the set of I bits of information stream, wherein each matrix of the pool is a set of M vectors, and wherein each vector of the set of M vectors corresponds to a respective transmit antenna of a set of M transmit antennas and is of length D;
- and
- transmitting a resource block across the set of M transmit antennas, wherein respective vectors of the set of M vectors are transmitted on the corresponding transmit antennas of the set of M transmit antennas and based at least in part on mapping respective entries of the respective vectors to respective resource elements of the resource block.
An apparatus for transmission of a set of I bits of information stream, comprising:
- at least one processor;
- at least one memory communicatively coupled to the at least one processor;
- and
- executable instructions code stored in the at least one memory, which when executed by the at least one processor, cause the at least one processor to:
- select, from a pool of at least 2I matrices, a matrix to uniquely represent the set of I bits of information stream, wherein each matrix of the pool is a set of M vectors, and wherein each vector of the set of M vectors corresponds to a respective transmit antenna of a set of M transmit antennas and is of length D;
- and
- transmit a resource block across the set of M transmit antennas, wherein respective vectors of the set of M vectors are transmitted on the corresponding transmit antennas of the set of M transmit antennas and based at least in part on mapping respective entries of the respective vectors to respective resource elements of the resource block.
A wireless device for wireless communications, comprising:
- means for selecting, from a pool of at least 2I matrices, a matrix to uniquely represent a set of I bits of information stream, wherein each matrix of the pool is a set of M vectors, and wherein each vector of the set of M vectors corresponds to a respective transmit antenna of a set of M transmit antennas and each vector is of length D;
- and
- means for transmitting a resource block across the set of M transmit antennas, wherein respective vectors of the set of M vectors are transmitted on the corresponding transmit antennas of the set of M transmit antennas and based at least in part on mapping respective entries of the respective vectors to respective resource elements of the resource block.
