Abstract: A transmitting apparatus according to one aspect of the present disclosure transmits a plurality of first transmission data and a plurality of second transmission data by using an OFDM (Orthogonal Frequency-Division Multiplexing) method. The transmitting apparatus includes frame configuring circuitry, which in operation, generates a frame including a first period in which a preamble is transmitted, a second period in which the plurality of first transmission data is multiplexed by a time division multiplexing method and is transmitted, and a third period in which the plurality of second transmission data is multiplexed by a frequency division multiplexing method and is transmitted; and transmitting circuitry that transmits the frame.

Abstract: Some aspects relate to apparatuses and methods for selecting a receiving beam based on hybrid channel based beamforming and codebook based beamforming. A user equipment (UE) can determine, based on a first measurement related to signal to noise ratio (SNR) and predetermined threshold values, whether the UE is in a low SNR state. If the UE is in a low SRN state, the UE can derive an estimated channel covariance matrix RCH for channels at a set of antenna elements of the UE based on channel based bearmforming (CHBF). Afterwards, a set of test bears {0, . . . Ntest−1} is selected based on the channel covariance matrix RCH, and a set of codebook measurement beams is further selected based on the set of test beams. A receiving beam is selected based on a set of measurements performed on the set of codebook measurement beams at the measurement opportunity for codebook based beamforming (CBBF).

Abstract: When transmitting signals from a plurality of base stations (broadcasting stations), the base stations include at least a first base station having a first antenna with a first polarization and a second base station having a second antenna with a second polarization that is different from the first polarization. Then, when the first base station transmits a signal from the first antenna having the first polarization, the second base station transmits the same signal as the first antenna of the first base station from a second antenna having the second polarization, at the same time.

Abstract: An electronic device may include communications circuitry, sensing circuitry, and a set of antennas having first and second feeds for covering different polarizations. The communications circuitry may transmit signals with a first polarization using each of the antennas and may concurrently transmit signals with a second polarization using all but a selected one of the antennas. The sensing circuitry may concurrently transmit sensing signals with the first polarization using one of the antennas and may receive sensing signals with the second polarization using the selected antenna. The sensing signals may include chirp signals generated to include muted periods that correspond to a range of frequencies that overlap frequencies at which the wireless circuitry is subject to radio-frequency interference. This may allow for concurrent wireless communications and sensing operations without interference between the communications circuitry and the sensing circuitry.

Abstract: A method for performing a beamformed transmission and/or reception in a wireless communication using an antenna array comprising a first sub-array of first antenna elements each having a first polarization and a second sub-array of second antenna elements each having a second polarization that is orthogonal to the first polarization is provided. The method comprises obtaining a first weight vector for the first sub-array and a second weight vector for the second sub-array. The first weight vector and the second weight vector optimize a utility function. The utility function comprises a first term depending on a first function of the first weight vector and on a second function of the second weight vector. The utility function further comprises a second term depending on either one of the first function and the second function. Performing the beamformed transmission using the obtained first weight vector and the second weight vector.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a reconfigurable intelligent surface (RIS) may select a weight vector, from a plurality of stored weight vectors, for enabling a spatially multiplexed communication, between a transmitter and a receiver, that includes two or more layers for each polarization of a plurality of polarizations for the spatially multiplexed communication. The RIS may receive the spatially multiplexed communication from the transmitter. The RIS may transmit the spatially multiplexed communication to the receiver in accordance with the weight vector. Numerous other aspects are described.

Abstract: There is provided mechanisms for performing a beam management procedure. A method is performed by a network node. The method comprises obtaining configuration information from a terminal device for which the network node provides network access. The configuration information specifies that the terminal device is in need for evaluating different polarization states in different time units during the beam management procedure. The method comprises performing the beam management procedure with the terminal device. The beam management procedure involves the network node to, per slot, transmit reference signals according to a reference signal transmission scheme. The reference signal transmission scheme depends on the obtained configuration information.

Abstract: Methods and apparatus for distinguishing between an antenna of a user equipment (UE) being blocked by a cover (e.g., a protective rubber or plastic case) or by human tissue (e.g., a finger or palm). The transmission power of uplink (UL) signals may be adjusted accordingly, with relatively higher transmission power for open space or a cover and relatively lower transmission power for human tissue. One example method for wireless communications by a UE generally includes transmitting a first signal from the UE, receiving a plurality of signals at the UE based on the transmitted first signal, determining values for at least two different types of parameters based on the received plurality of signals, determining an environmental scenario for the UE based on the values for the at least two different types of parameters, and transmitting a second signal using a transmission power based on the determined environmental scenario.
