Abstract:
A system (200) and method of making three way calls from a wireless communications device (10) having a phonebook (402) are disclosed. The method comprises the steps of selecting a first party to be called from a phonebook (402) residing on the wireless communications device, selecting a second party to be called from the phonebook (402), originating calls to the first and second parties, and joining the calls to the first and second parties in a three-way call. The method may also include the steps of waiting for user input before originating a call to the second party, playing a pre-recorded message to the first party before originating the call to the second party, and waiting for user input before joining the calls to the first and second parties in a three-way call. The system (200) comprises a transceiver (216) for transmitting data to and from a remote location via an antenna (218), a user input device (208) for selecting from a phonebook (402) first and second parties to be called, a storage area (220) for storing data indicative of the first and second parties to be called, and a central processing unit (202) operatively coupled to the storage area (220), the user input device (208) and the transceiver (216) for originating and joining the first and second parties in a three-way call with the user of the system (200). The system (200) may also include a visual display (206) and an audio tone generator (224).
Abstract:
Aspects of the present disclosure provide for the pairing of two or more interband time division duplex (TDD) carriers. In some examples disclosed herein, a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.

Abstract:
Un procedimiento de comunicación inalámbrica operable en una entidad de programación (102), que comprende: comunicarse de forma inalámbrica usando un primer intervalo de tiempo de transmisión, TTI, a través de una primera portadora, siendo la primera portadora una portadora de duplexado por división de tiempo, TDD; y comunicarse de forma inalámbrica usando un segundo TTI diferente del primer TTI y solapando una parte del primer TTI, a través de una segunda portadora emparejada con la primera portadora pero separada de la primera portadora en frecuencia, en el que el segundo TTI tiene una duración más corta que el primer TTI.
Abstract:
Aspects of the disclosure provide for a thin control channel structure that can be utilized to enable multiplexing of two or more data transmission formats. For example, a thin control channel may carry information that enables ongoing transmissions utilizing a first, relatively long transmission time interval (TTI) to be punctured, and during the punctured portion of the long TTI, a transmission utilizing a second, relatively short TTI may be inserted. This puncturing is enabled by virtue of a thin channel structure wherein a control channel can carry scheduling information, grants, etc., informing receiving devices of the puncturing that is occurring or will occur. Furthermore, the thin control channel can be utilized to carry other control information, not being limited to puncturing information. Other aspects, embodiments, and features are also claimed and described.
Abstract:
Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.
Abstract:
