A first electronic device according to various embodiments may select one of a plurality of representation matrices and one of a plurality of measurement matrices on the basis of a pattern and/or feature of data received from a sensor. The selection of the representation matrix and the measurement matrix may be performed on the basis of machine learning. Based on the selected representation matrix and measurement matrix, the first electronic device may adaptively compress at least a portion of the data. A second electronic device according to various embodiments may restore compressed data on the basis of the result of selecting the representation matrix and the measurement matrix. By dynamically selecting the representation matrix and the measurement matrix on the basis of machine learning, it is possible to reduce an error in the data restored by the second electronic device (e.g., a restoration error).

Provided is a communication system that can sustain a reduction in delay in FFT/IFFT processing by code blocking user data, even in a case where the functions of upper layers such as a MAC scheduler and the function of the radio physical layer are implemented separately. In a radio base station (communication system) including a central aggregation device 210 and a remote device 220, the central aggregation device 210 transmits code blocks in a number necessary for generating an OFDM symbol as a piece of data to the remote device 220, the code blocks being produced by dividing user data into units of encoding processing.

In some aspects, methods and apparatus for wireless communications are configured to generate a packet for wireless communication where the packet includes a mark symbol in a preamble of the packet where the mark symbol includes a signature or stamp field in the mark to provide protocol information that indicates the protocol of the packet, such as an 802.11 EHT packet. In some other aspects, a cyclic redundancy check field in the mark symbol may be manipulated in various ways to indicate the protocol of the packet in lieu of providing the signature or stamp field.

The present invention relates to providing control information within a search space for blind decoding in a multi-carrier communication system. In particular, the control information is carried within a sub-frame of the communication system, the sub-frame including a plurality of control channel elements. The control channel elements may be aggregated into candidates for blind decoding. The number of control channel elements in a candidate is called aggregation level. In accordance with the present invention, the candidates of lower aggregation levels are localized, meaning that the control channel elements of one candidate are located adjacently to each other in the frequency domain. Some candidates of the higher aggregation level(s) are distributed in the frequency.

A preamble of a physical layer (PHY) data unit that conforms to a first communication protocol is generated. The preamble includes a legacy field that is formatted according to a second communication protocol, and a signal field having a first orthogonal frequency division multiplexing (OFDM) symbol and a second OFDM symbol. The first OFDM symbol (i) immediately follows the legacy field and (ii) is modulated using binary phase shift keying (BPSK) modulation, whereas a third communication protocol specifies that an OFDM symbol, defined by the third communication protocol, that immediately follows the legacy field is modulated using BPSK modulation rotated by 90 degrees (Q-BPSK). The second OFDM symbol (i) immediately follows the first OFDM symbol and (ii) is modulated using Q-BPSK to indicate to a receiver device that conforms to the first communication protocol that the data unit conforms to the first communication protocol.
