  • Patent number: 11245461
    Abstract: A transmission method for transmitting a first modulated signal and a second modulated signal in the same frequency at the same time. Each signal has been modulated according to a different modulation scheme. The transmission method applies precoding on both signals using a fixed precoding matrix, applies different power change to each signal, and regularly changes the phase of at least one of the signals, thereby improving received data signal quality for a reception device.

  • Patent number: 11228397
    Abstract: A wireless transmission system includes a first wireless transmission device and a second wireless transmission device. The first wireless transmission device sets multiplex data to at least one predetermined bit contained in an input first packet and thereby generates a second packet containing the multiplex data, and transmits the second packet to the second wireless transmission device. The second wireless transmission device receives the second packet from the first wireless transmission device, performs error detection on the second packet, and when the error detection ends normally, extracts the multiplex data from the at least one predetermined bit in the second packet.

  • Patent number: 11218253
    Abstract: Systems, methods, and instrumentalities are disclosed for narrowband (NB) LTE operation. A WTRU may receive a first downlink data transmission, for example, via a physical downlink shared channel (PDSCH). The WTRU may determine to send a hybrid automatic repeat request (HARQ) acknowledgment (ACK) in response to receipt of the first downlink data transmission. The WTRU may transmit a first uplink reference signal. The WTRU may indicate the HARQ-ACK using a first cyclic shift index that is applied to the first uplink reference signal. The WTRU may determine to send a HARQ negative ACK (HARQ-NACK), for example, on a condition that a second downlink data transmission is not correctly received. The WTRU may send a second uplink reference signal. The WTRU may indicate the HARQ-NACK using a second cyclic shift that is applied to the second uplink reference signal.
