A sequence meeting a requirement for sending a signal by using a physical uplink control channel (PUCCH) is determined. The sequence is a sequence {fn} including N elements, and fn is an element in the sequence {fn}. The determined sequence {fn} is a sequence that meets a preset condition. Then the N elements in the sequence {fn} are respectively mapped to N subcarriers to generate and send a first signal. With the determined sequence, when the signal is sent by using the PUCCH, a low cross-correlation between sequences can be maintained, and a relatively small peak to average power ratio (PAPR) value and a relatively small and cubic metric (CM) value can be maintained. Therefore, a requirement in a communications application environment in which the signal is sent by using the PUCCH is met.

  • Patent number: 11159214
    Abstract: A wireless communications system (10) and a method therein for transmission of a downlink signal in a wireless communications network (100) supporting beamforming. The system estimates uplink channel information for a radio link from a wireless device (120) to a radio network node (110). Further, the system obtains downlink beamforming information related to the estimated uplink channel information from a machine learning unit (300). The machine learning unit comprises relationships between beamforming information and uplink channel information determined based on stored pairs of reported downlink beamforming information and measured uplink channel information. The obtained downlink beamforming information is applicable for the radio cell sector. Furthermore, the system transmits, towards the wireless device (120), a beamformed downlink signal using the obtained downlink beamforming information.

  • Patent number: 11145805
    Abstract: Utilizing the topological character of patterns in 3D structures is beneficial for information storage, magnetic memory and logic systems. One embodiment describes the use of topological knots, exemplified by a Möbius strip, in which a spin traversing along the band for a complete cycle will recover its original position, while having rotated away from its original orientation. The spins can respond to an external magnetic field, but cannot achieve a ferromagnetic state, in which all magnetic moments are pointing in the same direction, due to the topological knot. 3D assemblies of such nano-Möbius strips may form a prototype secure magnetic information storage device that are secure and with extremely low levels of energy dissipation.

  • Patent number: 11147043
    Abstract: Methods, systems, and devices for wireless communication are described. In order to exchange data over a given wireless communication network, a wireless device may first perform a cell acquisition procedure (e.g., to determine cell-specific information such as timing and frequency offsets, bandwidth, control channel formatting, etc.). In some systems, aspects of the timing information may be conveyed with scrambling codes applied to a master information block (MIB). Physical broadcast channel (PBCH) payloads, including MIB transmissions, may be jointly encoded with synchronization signal indices. Bursts of MIB transmissions may thus be decoded without blind decoding while maintaining error protection and low latency that may be necessary to obtain critical system information within the MIB.
