Abstract:
A method and apparatus can be configured to determine an uplink-downlink configuration. The method also transmits an indication of the uplink-downlink configuration. The transmitting the indication of the uplink-downlink configuration includes using physical layer signaling. The transmitting the indication of the uplink-downlink configuration also includes reusing an existing physical layer channel. The transmitting the indication of the uplink-downlink configuration is performed without extending physical layer associations
Abstract:
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).
Abstract:
Various communication systems may benefit from techniques for handling inter-band carrier aggregation (CA). For example, systems of the third generation partnership project (3GPP) long term evolution (LTE) advanced (LTE-A) may benefit from a uplink (UL) downlink (DL) configuration zero handling, particularly in cases where there is no physical hybrid automatic repeat request (HARQ) indicator channel (PHICH). For example, certain embodiments may be applicable to inter-band CA having different UL/DL configuration in use. A method can include triggering in a downlink subframe a first physical uplink shared channel transmission in a first hybrid automatic repeat request process. The method can also include triggering in the downlink subframe a second physical uplink shared channel transmission in a second hybrid automatic repeat request process. The secondary cell can be configured with time division duplex uplink/downlink configuration number zero. The triggerings can be performed by means of a single uplink grant but without a hybrid automatic repeat request indicator.
