20140301255 | SYSTEMS AND METHODS FOR CONFIGURATION SIGNALING - A User Equipment (UE) for receiving time-division duplexing (TDD) uplink/downlink (UL/DL) configurations is described. The UE includes a processor and instructions stored in memory that is in electronic communication with the processor. The UE receives a first TDD UL/DL configuration for a cell and secondary configuration information that includes at least a second TDD UL/DL configuration for the cell. | 2014-10-09 |
20140301256 | Uplink Power Control Enhancement for Dynamic Time Division Duplex Uplink-Downlink Reconfiguration - Systems, methods, apparatuses, and computer program products for power control enhancement are provided. One method includes retrieving, by an eNB, subframe type information in connection with uplink (UL)/downlink (DL) configuration. The method then includes simultaneously indicating, using physical layer signaling, at least one of the subframe type information and/or corresponding power control parameter set to a user equipment. In one example, the subframe type information and/or the corresponding power control parameter set may be indicated in reused bits of a transmit power command (TPC). | 2014-10-09 |
