20140126513 | METHOD OF PROVIDING CONTROL INFORMATION FOR USER EQUIPMENT - A method of providing control information for user equipments (UEs) in communication with a base station over a wireless communication system includes: mapping at least one enhanced-physical downlink control channel (E-PDCCH) on at least one allocated pair of physical resource blocks (PRBs) according to an enhanced-control channel element (ECCE) structure including a variable number of resource element groups (REGs); and varying the number of REGs in an E-CCE structure. | 05-08-2014 |
20140301232 | APPARATUS AND METHOD FOR CSI CALCULATION AND REPORTING - A method of measuring Channel State Information (CSI) in a multiple input/multiple output (MIMO) communication system including at least one base station (eNodeB) and at least one User Equipment (UE), the method including: receiving a Channel State Information Reference Signal (CSI-RS) carried in a sub-frame of a radio frame of the communication system at the at least one UE from the at least one eNodeB over at least one downlink. channel therebetween; extracting CSI-RS Resource Elements (RE) from the CSI-RS sub-frame; and using the extracted CSI-RS REs to perform downlink channel estimations for active pairs of receiving and transmitting antennas of the UE and the eNodeB respectively to derive the CSI. | 10-09-2014 |
20140341141 | APPARATUS AND METHOD OF PROVIDING MACHINE TYPE COMMUNICATION - In a wireless communications network providing a machine-type communications (MTC) service, a portion of a frequency spectrum is allocated to a MTC device to communicate between a base station and other MTC devices. MTC system information is transmitted/received from/to the MTC device through the portion of the frequency spectrum and may include channel information. The portion of the frequency spectrum may be used for a Long Term Evolution (LTE) wireless communication network. | 11-20-2014 |

20150195817 | METHOD OF CONTROL SIGNALING TRANSMISSION AND RECEPTION FOR USER EQUIPMENT IN A LTE COMMUNICATION SYSTEM - A method implemented in a base station used in a wireless communications system is disclosed. The method includes transmitting, to a user equipment (UE), an indication of a type of enhanced physical downlink control channel (ePDCCH) transmission, where the type of ePDCCH transmission comprises either localized transmission or distributed transmission, and transmitting, to the UE, an indication of the number of physical resource block (PRB) pairs allocated for the ePDCCH transmission, where the indication of the number of PRB pairs allocated for the ePDCCH transmission is conveyed in 2 or 3 bits. Other methods, apparatuses, and systems also are disclosed. | 07-09-2015 |
