    摘要: A method of measurement gap reporting and configuration is provided. In a mobile network, a UE receives a capability enquiry message from a serving base station. The UE comprises one or more radio frequency modules that support a list of frequency bands and a list of carrier aggregation (CA) band combinations. In response to the enquiry, the UE transmits capability information containing measurement parameters to the base station. In one embodiment, the measurement parameters comprise need-for-gap parameters for each frequency band and each CA band combinations associated with a list of to-be-measured frequency bands of target cells. Based on the reported measurement parameters, the eNB transmits a measurement configuration message to the UE. Finally, the UE transmits a measurement gap application message back to the base station. The measurement gap application message indicates whether the UE applies MG for each configured component carrier.

    摘要: A method of radio link monitoring (RLM) and radio link failure (RLF) handling over a secondary serving cell (SCELL) is proposed. In a wireless network, a user equipment (UE) establishes a radio resource control (RRC) connection with a base station (eNB). The UE applies carrier aggregation for multiple component carriers (CCs) configured as multiple serving cells. The UE performs radio link monitoring over a primary serving cell (PCELL). The UE also performs radio link monitoring over a secondary serving cell (SCELL). The SCELL belongs to a CC group of one or more CCs, and used as a reference cell for the CC group. When SCELL performance is below pre-defined criteria, the UE and the eNB apply certain actions over the SCELL or all CCs in the CC group. The proposed SCELL RLM/RLF handling prevents spurious and uncontrollable uplink SCELL transmission and interference to other UEs.

    摘要: A method of managing access to problem event information collected by a User Equipment (UE). In one novel aspect, access to the problem event information is determined by a public land mobile network (PLMN) list stored in the UE. The UE collects problem event information, stores a PLMN list, and sends an indication that problem event information is available to a Radio Access Network (RAN) controller. In response, the RAN controller sends a request indicator to the UE requesting the event information. The UE transmits the requested event information when the requesting PLMN is included in the PLMN list stored in the UE. In one embodiment, the event information includes Minimization Drive Test (MDT) measurement information. In another embodiment, the event information includes radio link failure information. The solution enables managing access to problem event information with maximum simplicity and minimum impact to existing systems.

    摘要: 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.

    摘要: A method of failure event report correlation is proposed. A UE detects a failure event in a first cell served by a first base station, and the UE is assigned with a previous C-RNTI. The failure event may include a radio link failure, a handover failure, or a RACH failure. The UE then performs an RRC establishment procedure with a second base, and the UE is assigned with a new C-RNTI. After the RRC establishment, the UE transmits a failure event report along with the correlation information to the second base station. The second base station then forwards the failure event report and the previous C-RNTI to the first base station. The first base station can correlate the failure event report with the previous failure event based on the previous C-RNTI to avoid double bookkeeping and improve MRO decision for SON.
