| 20150063339 | METHOD AND APPARATUS FOR CONFIGURING WIRELESS COMMUNICATION USING DEVICE NAMES IN ELECTRONIC DEVICE - A method and an electronic device which is able to configure wireless communication using device names in the electronic device are provided. The method for wireless communication in the electronic device includes configuring communication connection information by designating device names to be used for connection with communication devices; and providing a communication service by establishing a wireless communication link to the communication device using the designated device name and communicating with the communication device. Configuring the communication connection information includes displaying a wireless communication configuration screen; displaying, upon selection of a device name displayed on the wireless communication configuration screen, a default device name of the communication device and a list of account names of accounts registered with the communication device; and designating an account name selected from the displayed list as a device name. | 2015-03-05 |
| 20150063340 | System and Method for Using SIC to Solve WiFi Collisions - An embodiment method of collision resolution includes receiving a frame A and a colliding frame B. The frame A and the colliding frame B are received over a channel and overlap in time. The method also includes decoding the frame A. The method also includes recovering and decoding the colliding frame B, at least partially, using successive interference cancellation (SIC). | 2015-03-05 |
| 20150063341 | WIRELESS COMMUNICATION APPARATUS - A wireless communication apparatus supports at least a second wireless communication scheme between a first wireless communication scheme and the second wireless communication scheme. The first wireless communication scheme requires that a wireless medium is determined to be busy when a reception level is equal to or greater than a minimum reception sensitivity level of a physical scheme. The apparatus includes a first processing unit and a second processing unit. The first processing unit is configured to set a value lower than a maximum transmission power of the first wireless communication scheme, for a maximum transmission power of the second wireless communication scheme and set a value greater than the minimum reception sensitivity level of the physical scheme, for a carrier sense level, when the second wireless communication scheme is used. The second processing unit is configured to carry out carrier sense using the carrier sense level. | 2015-03-05 |
| 20150063342 | Retrospective Ephemeris Collection - A method for collecting a satellite data stream is disclosed. The method includes: receiving satellite signals; storing the received satellite signals; completing bit synchronization and subframe synchronization of the received satellite signals; recovering a portion of the satellite data stream from the satellite signals stored prior to completing bit synchronization and subframe synchronization. | 2015-03-05 |
| 20150063343 | RESOURCE ALLOCATION FOR DISTRIBUTED DEVICE-TO-DEVICE SYNCHRONIZATION - Methods, systems, and devices are described for synchronizing a user equipment (UE) in a device-to-device communications network. The UE may scan for a synchronization signal transmitted from another UE in the network. A synchronization frame including a plurality of slots to use may be identified based at least in part on a result of the scanning. The identified synchronization frame may be analyzed to select a slot to use from the plurality of slots of the synchronization frame. A synchronization signal may be transmitted using the identified synchronization frame and the selected slot. | 2015-03-05 |
| 20150063344 | DATA BOUNDARY DETERMINING METHOD, INDICATION INFORMATION SENDING METHOD, AND APPARATUSES THEREOF - Embodiments of the present invention disclose a data boundary determining method, an indication information sending method, and apparatuses thereof. The boundary determining method includes: acquiring, by a base station in which a non-reference cell locates, timing information of a reference cell, or a parameter used to determine boundary information of a high speed dedicated physical control channel (HS-DPCCH); and determining, by the base station, the boundary information of the HS-DPCCH according to the timing information of the reference cell or the parameter, where the boundary information is used by the base station to search for the HS-DPCCH. The present invention solves a technical problem in the prior art that a base station in which a non-reference cell locates is not capable of finding a correct boundary of the HS-DPCCH and therefore causes a decrease in downlink data transmission performance. | 2015-03-05 |
| 20150063345 | IP MULTIMEDIA SUBSYSTEM SUPPORT FOR PRIVATE BRANCH EXCHANGES - According to an aspect of the present invention there is provided a method of providing support for multiple links between a Private Branch Exchange (PBX) and an IP Multimedia Subsystem (IMS). The method comprises, at an IMS Application Server (AS), configuring the AS with capacity information relating to each of the multiple links, receiving SIP call control messages relating to calls involving the PBX and thereby maintaining usage information for each of the multiple links, the usage information indicating which of the multiple links is being used for each ongoing call involving the PBX. The method further comprises using the capacity information and the usage information relating to each of the multiple links to select one of the multiple links to carry an incoming call terminating at the PBX, and modifying SIP call control messages relating to the incoming call to ensure that the incoming call is carried by the selected link. | 2015-03-05 |
