In one embodiment, the method includes (i) the UE stops uplink transmission(s) to the second cell after detection of the radio link failure, and/or (ii) the UE deactivates the second cell after detection of the radio link failure. | 10-02-2014 |
20140355533 | METHOD AND APPARATUS FOR TTI (TRANSMISSION TIME INTERVAL) BUNDLING FOR SMALL CELL ENHANCEMENTS IN A WIRELESS COMMUNICATION SYSTEM - A method and apparatus are disclosed for TTI bundling for small cell enhancements in a wireless communication system. The method includes a UE (User Equipment) that is served by a first cell controlled by a first eNB (evolved Node B). The method also includes the UE receives a first RRC (Radio Resource Control) message for configuring a TTI bundling. The method further includes the UE receives a second RRC message for adding a second cell controlled by a second eNB to the UE, wherein the second cell is configured with a PUSCH (Physical Uplink Shared Channel). In addition, the method includes the UE applies the TTI bundling for uplink transmissions on the first cell and does not apply the TTI bundling for uplink transmissions on the second cell. | 12-04-2014 |
20150049674 | METHOD AND APPARATUS FOR DEVICE TO DEVICE DISCOVERY IN A WIRELESS COMMUNICATION SYSTEM - A method and apparatus are disclosed for device to device discovery in a wireless communication system. The method includes a UE (User Equipment) receiving information included in a system information message broadcasted by a cell. The method also includes the UE finds, based on the information, a neighboring cell which provides resources for D2D discovery. | 02-19-2015 |
20150063260 | METHOD AND APPARATUS FOR DEVICE TO DEVICE SERVICE IN A WIRELESS COMMUNICATION SYSTEM - A method and apparatus are disclosed for performing a device to device discovery in a wireless communication system. The method includes a first UE connects with a network. The method also includes the first UE receives a request from the network instructing the first UE to perform a D2D discovery to find a second UE. The method further includes the first UE performs the D2D discovery. | 03-05-2015 |
20150078153 | METHOD AND APPARATUS FOR APPLYING SIGNALING OF WLAN-3GPP INTERWORKING - A method and apparatus are disclosed for applying signaling of WLAN-3GPP interworking. The method includes receiving a first configuration of an interworking parameter by dedicated signalling, wherein the first configuration is not released when the UE enters idle mode. The method also includes receiving a second configuration of the interworking parameter by broadcast signalling when the UE is in idle mode, and overriding the first configuration with the second configuration. | 03-19-2015 |
