Includes: acquiring configuration information of the control channel, where the configuration information includes at least one of the following information: a configuration period of the control channel, resource occupation indication information, and a configuration period start position, where the resource occupation indication information is used to indicate physical resource blocks PRBs occupied by the control channel in the configuration period, and the configuration period start position is used to indicate a corresponding start point at the beginning of the configuration period; and sending the configuration information to a neighboring base station, so that the neighboring base station performs adjustment according to the configuration information to reduce interference to the control channel of the base station. | 2015-12-24 |
20150373732 | USER EQUIPMENT AND METHODS FOR CSI ENHANCEMENTS USING INTERFERENCE CANCELLATION AND SUPPRESSION RECEIVERS - In providing feedback to an eNB in an LTE network for downlink scheduling and link adaptation, a UE issues a channel state information (CSI) report that includes a channel quality index (CQI). The reported CQI should include all UE receiver processing capabilities, including NAICS (network assisted interference cancellation and suppression) capability to cancel and suppress interference. Described are measures that may be taken to provide more accurate reporting of CSI by a terminal with NAICS capability. | 2015-12-24 |
20150373733 | METHOD AND APPARATUS FOR CONFIGURING AND USING SMALL DATA RADIO BEARERS - Apparatuses and methods for control of small data transmission by a user equipment (UE) are described herein. The UE may determine that data to be transmitted by the UE is small data if a size of the data is below a threshold. The UE may transmit a message indicating that the UE shall be transmitting small data responsive to determining that data to be transmitted by the UE is small data. The UE may receive a radio resource control (RRC) signal from an evolved Node B (eNodeB) that includes a logical channel identifier (LCID) of a small data radio bearer (SDRB) configured for transmission of small data. The UE may transmit small data on the SDRB subsequent to receiving the RRC signal from the eNodeB. The UE may refrain from transmitting other than small data on the SDRB. Other apparatuses and methods are described. | 2015-12-24 |
20150373734 | Methods and Arrangements for Optimizing Radio Resource Utilization at Group Communications - The present invention relates to methods and arrangements of optimizing radio resource utilization at a group communication for members of a specific group in a communication network system, comprising communication net-work nodes ( | 2015-12-24 |
20150373735 | TOPOLOGY-INDEPENDENT DISSEMINATION OF ALARM DATA ABOVE NETWORK PRIORITY - In one embodiment, a method comprises receiving, by a network device, a data packet specifying alarm data generated by a sensor node; and outputting, by the network device, the data packet at an alarm level priority that is higher than any network-level priority of any wireless routing topology. | 2015-12-24 |
