Abstract: Systems and Methods for supporting carrier aggregation with different TDD configurations are proposed. In a first novel aspect, corresponding apparatus structure is described. In a second novel aspect, aggregation constraint is discussed. In a third novel aspect, transceiving mechanisms over multiple component carriers in DL/UL overlapped subframes are proposed. For simultaneous DL/UL transceiving, band combination indication methods are proposed, and HARQ feedback mechanisms are proposed. For non-simultaneous DL/UL transceiving, transceiving configuration methods are proposed, and the same HARQ feedback mechanisms are proposed. In a fourth novel aspect, CQI/RLM/RRM measurement mechanisms are proposed. In a fifth novel aspect, UE capability signaling mechanisms are proposed. The objective is to support flexible aggregation, to enhance DL data throughout, and to improve UL transmit power efficiency.

Abstract: A method of using additional uplink measurements for MDT UL coverage is provided. A base station (eNodeB) establishes a radio resource control (RRC) connection with a user equipment (UE) in a mobile communication network. The eNodeB and the UE are configured for Minimization of Drive Test (MDT). The eNodeB receives a Power Headroom Report (PRH) corresponds to a Physical Uplink Shared Channel (PUSCH) from the UE, and forwards the PHR to an MDT server. The eNodeB performs uplink measurement of a Demodulation Reference Signal (DM-RS) allocated in the PUSCH. The uplink measurement also involves measuring an uplink Received Interference Power (RIP) associated with the PUSCH. The eNodeB then reports uplink measurement results to the MDT server. The MDT server is able to determine uplink coverage based on the PHR and the uplink measurement results.
