Latest Patents

One of his latest patents is titled "Systems and methods for different TDD configurations in carrier aggregation." This patent proposes various systems and methods to support carrier aggregation with different Time Division Duplex (TDD) configurations. The first novel aspect describes the corresponding apparatus structure. The second aspect discusses aggregation constraints, while the third aspect proposes transceiving mechanisms over multiple component carriers in downlink (DL) and uplink (UL) overlapped subframes. For simultaneous DL/UL transceiving, he introduces band combination indication methods and Hybrid Automatic Repeat Request (HARQ) feedback mechanisms. For non-simultaneous DL/UL transceiving, he proposes transceiving configuration methods along with the same HARQ feedback mechanisms. Additionally, the patent includes novel aspects related to Channel Quality Indicator (CQI), Radio Link Monitoring (RLM), and Radio Resource Management (RRM) measurement mechanisms, as well as User Equipment (UE) capability signaling mechanisms. The objective of this patent is to support flexible aggregation, enhance DL data throughput, and improve UL transmit power efficiency.

Another significant patent is focused on "Minimization of drive tests for uplink link coverage." This method utilizes additional uplink measurements for Minimization of Drive Test (MDT) in uplink coverage. In this process, 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 MDT, where the eNodeB receives a Power Headroom Report (PHR) corresponding to a Physical Uplink Shared Channel (PUSCH) from the UE and forwards it to an MDT server. The eNodeB performs uplink measurements of a Demodulation Reference Signal (DM-RS) allocated in the PUSCH, which also includes measuring an uplink Received Interference Power (RIP) associated with the PUSCH. The eNodeB then reports the uplink measurement results to the MDT server, which can determine uplink
