User equipment (UE) applies a first code division multiplex access (CDMA) code to a baseband signal to generate a first signal, and a second CDMA code to the baseband signal to generate a second signal. The UE then transmits the first signal to a receiving device via a first antenna, and the second signal to the receiving device via a second antenna. The receiving device receives the first and second signals as a combined signal at an antenna, and extracts the first signal from the combined signal using the first CDMA code, and extracts the second signal from the combined signal using the second CDMA code. The CDMA codes may be real-valued or complex-valued. In some embodiments, the UE may separate the baseband signals into first and second portions, and transmit the first portion as part of the first signal and the second portion as part of the second signal.

Inventive concepts and embodiments associated therewith are provided wherein a first device transmits first information to a destination device using a first band of frequencies comprising microwave frequencies and cellular frequencies while a second device, that comprises a connection to the first device, transmits second information to the destination device using a second band of frequencies that differs from the first band of frequencies, is devoid of cellular frequencies and comprises microwave frequencies. In some embodiments, the connection of the second device to the first device comprises a wireless connection. In further embodiments, at least one of said first and second devices comprises a smartphone.

Inventive concepts relating to open access points are described wherein a first wireless service is provided to one or more devices associated with a first residence using a first band of frequencies and a second wireless service is provided to one or more other devices not associated with the first residence using a second band of frequencies. According to some embodiments, an access point is configured to provide the first wireless service to the one or more devices associated with the first residence responsive to an access code that has been provided to the one or more devices and is further configured to provide the second wireless service to the one or more other devices not associated with the first residence. The first wireless service differs from the second wireless service, and the second band of frequencies differs from the first band of frequencies and comprises 900 MHz.

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.

The present invention relates to a method and a device for transmitting a device-to-device (D2D) synchronization signal of a first terminal in a wireless communication system. More specifically, the method comprises the steps of: setting at least one candidate value for a D2D synchronization signal period; and determining a D2D synchronization signal period for transmitting/receiving a D2D signal to/from a second terminal from among the at least one candidate value.

A UE is described that includes a higher layer processor configured to receive a dedicated RRC configuration message which configures a License Assisted Access (LAA) cell. The UE also includes a PDCCH receiver configured to receive a first PDCCH and a second PDCCH. The first PDCCH is a PDCCH with CRC scrambled by CC-RNTI, and with a DCI format which contains a subframe configuration field. The second PDCCH is a PDCCH with DCI formats for scheduling physical uplink shared channel(s) (PUSCH(s)) on the LAA cell. If the first PDCCH is detected in subframe n, and the first PDCCH is not detected in subframe n−1, and if the number of occupied OFDM symbols for the subframe n indicated by the subframe configuration field in the subframe n is less than 14, the UE is not required to receive any other physical channels in subframe n except for the second PDCCH.

Inventive concepts and embodiments associated therewith are provided wherein an auxiliary device, that is attached to a person, is configured to function in cooperation with a destination device that is on the person. In some embodiments, the auxiliary device is uniquely associated with specific information that is to be conveyed to the destination device following reception of a signal by the auxiliary device. Embodiments are disclosed wherein, following reception of the signal by the auxiliary device, the auxiliary device processes the signal and then conveys the specific information that is uniquely associated therewith to the destination device without direct human interaction with the auxiliary device. In some embodiments, the auxiliary device comprises a personal wearable device and the destination device comprises a smartphone.

The present invention relates to single carrier modulation schemes, and presents a transmitter device, a receiver device and a transceiver device for a single carrier modulation scheme.
