    Abstract: Embodiments are provided to implement a time/power/frequency hopping scheme for device-to-device (D2D) discovery. The embodiments improve the UE detection of D2D discovery signals from neighboring UEs and account for large number of UEs' discovery signals. This is achieved by having neighboring UEs transmitting at different time instances and at different power levels. Further, neighboring UEs can be configured to transmit on different frequencies. This is achieved by assigning different time/power/frequency sequences to different UEs. An embodiment method includes transmitting, to a UE, parameters a hopping pattern of a first sequence of resources for transmitting a discovery signal by the UE and of a second sequence of resources for receiving a second discovery signal by the UE. The first sequence of resources comprises at least one of a sequence of time instances and a sequence of power levels. The second sequence of resources comprises time instances.

  • Patent number: 9414269
    Abstract: Systems and methods for transmission of measurement reports are provided. In some cases, once a mobile station transmits a measurement report for a cell, such as an uncontrolled cell, then the mobile station transmits some further minimum number of measurement reports. In some cases, a mobile station can only transmit measurement reports for a cell up to some maximum or for some specified time. The mobile station transmits measurement reports using two formats. In the first, the cell is identified using routing parameters; in the second, the cell is not identified using routing parameters. The network is able to associate messages sent using the two formats.

  • Patent number: 9386467
    Abstract: The present invention has an object to provide a communication system capable of appropriately providing services while improving a data rate using carrier aggregation. In Step ST1408, of a cell1 and a cell2 of a base station A, RRC connection is established between the cell1 and a UE, and the cell1 becomes a primary cell (PCell). Then, in Step ST1418, the cell1 determines to configure the cell2 as a secondary cell (SCell) to be aggregated with the own cell. Then, the cell1 notifies the UE of the above in Step ST1419. Upon this notification, the operation of restricting access to the cell2 from the UE is stopped by an MME, and thereafter, communication between the UE and the cell2 is started in Step ST1422.

  • Patent number: 9363038
    Abstract: Methods and apparatus for processing channel quality information (CQI) and scheduling resources subject to cooperative resource allocation based on the CQI are provided. To convey the CQI for protected/unprotected subframes in a single report, a new vector CQI format may be utilized. Two alternatives for CQI processing this vector format and the advantages of each are described. In the first alternative, a single entry from the CQI vector is selected for processing by a downlink scheduler and/or other media access control (MAC) blocks (e.g., a PHICH, DCI power control, and/or PDCCH scheduler). In the second alternative, the selection from the CQI vector is made on a per-subframe basis, and both the subframe and the selected CQI element are processed by the downlink scheduler and/or the other MAC blocks. In this manner, better scheduling decisions may be made using the CQI vector.
