Below, the components of the terminal in the above-described wireless communication system are shown. The components of the terminal described below are components of a general-purpose terminal supported by a wireless communication system and may be merged or integrated with the components of the terminal according to the above-mentioned contents, and may be compared to the previous drawings to the extent of some overlap or conflict. The content explained with reference may be interpreted as having priority. The terms “-module”, “-unit”, or “-er” used below may refer to a unit that processes at least one function.

The terminal includes a communication interface, a storage unit, and a controller.

The communication interface performs the function of transmitting and receiving signals through a wireless channel. For example, the communication interface performs conversion between baseband signals and bit streams according to the system's physical layer standards. For example, in data transmission, a communication interface encodes and modulates the transmitted bit stream to generate complex symbols. Additionally, when receiving data, the communication interface demodulates and decodes the base band signal to reconstruct the received bit stream. Additionally, the communication interface up-converts the base band signal into an RF band signal, transmits the converted signal through an antenna, and then down-converts the RF band signal received through the antenna into a base band signal. For example, the communication interface includes a transmission filter, reception filter, amplifier, mixer, oscillator, and digital-to-analog convertor (DAC). , analog-to-digital convertor (ADC), etc.

Additionally, the communication interface may include multiple transmission and reception paths. Additionally, the communication interface may include at least one antenna array including a plurality of antenna elements. On the hardware side, the wireless communication interface may include digital circuits and analog circuits (eg, radio frequency integrated circuit, RFIC). A digital circuit may be implemented with at least one processor (e.g., DSP). The communication interface may include multiple RF chains. The communication interface may perform beamforming.

The communication interface transmits and receives signals as described above. Accordingly, a communication interface may be referred to as a “transmitter,” “receiver,” or “transceiver.” Additionally, in the following description, transmission and reception performed through a wireless channel may be used to include processing performed in the communication interface as described above.

The storage unit stores data such as basic programs, applications, and setting information for the operation of the terminal. The storage unit may include volatile memory, non-volatile memory, or a combination of volatile memory and non-volatile memory. Additionally, the storage unit provides stored data upon request from the controller.

The controller controls the overall operation of the terminal. For example, a controller sends and receives signals through a communication interface. Additionally, the controller records data in the storage and reads the recorded data. The controller can perform the protocol stack functions required by communication standards. According to another implementation, a protocol stack may be included in the communication interface. For this purpose, the controller may comprise at least one processor or microprocessor or may reproduce part of a processor. Additionally, a part of the communication interface or controller may be referred to as a communication processor (CP).

According to an embodiment of the present invention, a controller can control a terminal to perform an operation according to an embodiment of the present invention.

Below, a communication interface in a wireless communication system is illustrated.

The communication interface includes encoding and modulation circuitry, digital beamforming circuitry, a plurality of transmission paths, and analog beamforming circuitry.

Encoding and modulation circuitry performs channel encoding. At least one of a low-density parity check (LDPC) code, a convolutional code, and a polar code may be used for channel encoding. The encoding and modulation circuit generates modulation symbols by performing constellation mapping.

A digital beamforming circuit performs beam forming on digital signals (eg, modulation symbols). For this purpose, the digital beamforming circuit multiplexes the modulation symbols by beamforming weight values. Beamforming weights can be used to change the size and wording of the signal and may be referred to as a “precoding matrix” or “precoder.” The digital beamforming circuit outputs digital beamformed modulation symbols through a plurality of transmission paths. At this time, depending on the multiple input multiple output (MIMO) transmission method, modulation symbols may be multiplexed or the same modulation symbol may be provided to multiple transmission paths.

A plurality of transmission paths convert digital beamformed digital signals into analog signals. To this end, each of the plurality of transmission paths may include an inverse fast Fourier transform (IFFT) calculation unit, a cyclic prefix (CP) insertion unit, a DAC, and an upconversion unit. The CP insertion unit is for the orthogonal frequency division multiplexing (OFDM) method and can be omitted when applying another physical layer method (e.g., a filter bank multi-carrier (FBMC)). That is, multiple transmission paths provide independent signal processing processes for multiple streams generated through digital beamforming. However, depending on the implementation, some elements of multiple transmission paths may be commonly used.

The analog beamforming circuit performs beamforming on analog signals. For this purpose, the digital beamforming circuit multiplexes the analog signal by beamforming weighting values. Beamformed weights are used to change the size and wording of the signal. More specifically, depending on the connection structure between a plurality of transmission paths and antennas, the analog beamforming circuit can be configured in various ways. For example, each of the plurality of transmission paths may be connected to one antenna array. In another example, multiple transmission paths may be connected to one antenna array. In another example, multiple transmission paths may be adaptively connected to one antenna array or may be connected to two or more antenna arrays.
