Systems/methods are disclosed wherein interconnected first and second transmitters are used to convey information to a destination device by wirelessly transmitting by the first transmitter first data using first frequencies and, responsive to a size of data that is to be transmitted to the destination device, wirelessly transmitting by the second transmitter second data using second frequencies. According to some embodiments, the first and second data are transmitted to the destination device simultaneously in time. According to further embodiments, a smartphone and/or a base station comprises the first and second transmitters. Aggregation of the first and second data is performed by the destination device.

A transmission apparatus includes a data-block generating unit that generates and outputs a data block including fixed sequence symbols whose signal values are formed of a fixed sequence and data symbols, a pilot-block generating unit that generates and outputs a pilot block including the fixed sequence symbols and pilot symbols that are fixed symbols known on a reception side, and an output control unit to which the data block and the pilot block are inputted, which controls whether the data block or the pilot block is outputted.

In order to perform UL transmission in a future radio communication system, a user terminal comprising: a generating section that generates an uplink (UL) signal to transmit to a radio base station; and a control section that controls transmission of the UL signal. The control section switches between OFDMA based transmission and SC-FDMA based transmission to apply to the UL signal. In addition, the user terminal controls the OFDMA based transmission and the SC-FDMA based transmission autonomously or based on information transmitted from the radio base station.

Systems/methods are disclosed whereby a device is configured to provide a first wireless service by using one or more auxiliary devices that is/are proximate thereto and is/are associated with unique identities known to the device. Also, a second wireless service is provided by the device by using one or more other auxiliary devices that is/are proximate thereto but is/are not associated with any specific unique identities known to the device. According to some embodiments, the first wireless service is based upon a Bluetooth protocol and an Ultra-Wide Band (UWB) Protocol, the second wireless service is based upon a Bluetooth Protocol and the device comprises a smartphone.

A system/method is disclosed wherein, according to some embodiments, an access point provides a first wireless service to a first device and further provides a second wireless service to a second device; wherein the access point provides the first wireless service to the first device responsive to a special access code that has been provided to the first device; wherein the access point further provides the second wireless service to the second device absent the special access code having been provided to the second device; wherein the first wireless service is more bandwidth intensive than, and differs from, the second wireless service; and wherein the second wireless service is provided to the second device using a 900 MHz band of frequencies.

A transmitter is configured to convey N bits of information and L bits of information, for a total of N+L bits of information, to a destination device via an auxiliary device. The transmitter is configured to select, from a plurality of auxiliary devices that are respectively associated with different possible states of the L bits of information, an auxiliary device that is associated with a state of the L bits of information to be conveyed. L may be ?1. The transmitter is also configured to convey the N+L bits of information from the transmitter to the destination device via the selected auxiliary device, without the transmitter transmitting any of the L bits of information to the destination device or the selected auxiliary device, by transmitting a signal to the selected auxiliary device. This signal comprises the N bits of information. N may be ?0.

Systems/methods are disclosed wherein, responsive to a size of data that is to be transmitted to a device, responsive to at least one other parameter and/or responsive to receiving instructions from the device, wirelessly transmitting to the device, over first, second, third and/or fourth non-overlapping intervals of time, respective first, second, third and/or fourth pluralities of subcarriers using respective first, second, third and/or fourth sets of frequencies; and further using respective first, second, third and/or fourth air interfaces that differ from one another in a physical layer aspect thereof.
