The wireless device transmits second uplink signals in the second carrier group employing the second secondary carrier as the timing reference carrier. | 2014-01-09 |
20140010164 | METHOD OF MANAGING AUTHORIZATION OF PRIVATE NODE B IN A WIRELESS COMMUNICATION SYSTEM AND RELATED DEVICE - A method of managing authorization of a private node-B in a wireless communication system is disclosed. The method includes performing cell searching, when a cell is found, reading system information corresponding to the cell, and then determining authorization validity of the private node-B according to the system information and licensed band area corresponding to the private node-B. | 2014-01-09 |
20140010165 | COMMUNICATION METHOD FOR WIRELESS TERMINAL AND HOST DEVICE, WIRELESS TERMINAL, AND HOST DEVICE - The present invention provides a communication method for a wireless terminal and a host device, a wireless terminal, and a host device. The method includes: reporting, by a wireless terminal, a port type of a port corresponding to the wireless terminal to a host device, where the port type is based on a network layer data transfer protocol, so that the host device drives the port by using a port driver corresponding to the port type; establishing, by the wireless terminal, a communication link that is based on the network layer data transfer protocol between the wireless terminal and the host device through interaction with the host device via the port; and transmitting, by the wireless terminal, a service packet and a type of the service packet via the communication link that is based on the network layer data transfer protocol. | 2014-01-09 |
20140010168 | SOFTWARE CONFIGURABLE DISTRIBUTED ANTENNA SYSTEM AND METHOD FOR BANDWIDTH COMPRESSION AND TRANSPORT OF SIGNALS IN NONCONTIGUOUS FREQUENCY BLOCKS - A method for transporting communications signals includes receiving an analog IF signal at a first unit. The analog IF signal includes a first carrier having a first frequency and a first bandwidth and a second carrier having a second frequency different from the first frequency and a second bandwidth. The analog IF signal is converted to a digitally sampled IF signal having the first carrier located in a first Nyquist zone, the second carrier located in a second Nyquist zone, an image of the first carrier located in a third Nyquist zone, and an image of the second carrier located in the third Nyquist zone. The image of the first carrier and the image of the second carrier is transmitted from the first unit to a second unit, where the image of the first carrier and the image of the second carrier is then converted to the analog IF signal. | 2014-01-09 |
20140010169 | DEVICE-EMPOWERED RADIO RESOURCE ASSIGNMENT - A system and method are provided for mitigating interference between wireless access points (APs). A user equipment (UE) device uses a first set of radio resources to wirelessly communicate with a first AP and a second set of radio resources to wirelessly communicate with a second AP. The UE device then uses the first and second radio resources to communicate cooperation data between the first and second access points to mitigate interference thereinbetween. | 2014-01-09 |
