摘要： A method of TDM in-device coexistence (IDC) interference avoidance is proposed. In a wireless communication device, a first radio module is co-located with a second radio module in the same device platform. The first radio module obtains traffic and scheduling information of the second radio module. The first radio module then determines a desired TDM pattern based on the traffic and scheduling information to prevent IDC interference with the second radio module. The first radio module also transmits TDM coexistence pattern information based on the desired TDM pattern to a base station. In one embodiment, the TDM coexistence pattern information comprises a recommended TDM pattern periodicity and a scheduling period to maximize IDC efficiency subject to limited level of IDC interference possibility. In one specific example, the TDM coexistence pattern information comprises a set of discontinuous reception (DRX) configuration parameters defined in long-term evolution (LTE) 3GPP standards.

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 FFR (fractional frequency reuse)-based network MIMO (multiple-input multiple-output) transmission architecture in a cellular system that employs cell sectoring using directional antennas. Each cell is sectorized into three outer sectors using three directional antennas which transmit in three different directions using three different frequency subbands. The cell sectors are arranged based on a frequency partition scheme so that three sectors in three neighboring cells form a coordinated group for network MIMO transmission. A regular and a rearranged frequency partition are described. Further, a practical implementation of SON (self organizing network)-based three-cell FFR-based network MIMO for a wireless OFDM system is described. In this implementation, a server connected to multiple base stations (BSs) defines multiple coordinated groups for coordinated MIMO transmission, and the BSs within each coordinated group negotiate a common radio resource region (a composite time-frequency region), and selects a serving mobile station to participate in the coordinated MIMO transmission.

摘要： A fast feedback mechanism is provided in a contention-based ranging procedure. A Subscriber Station (SS) initializes a ranging procedure by sending a ranging code on a selected ranging opportunity for resource access to a Base Station (BS) on a shared ranging channel in a previous uplink frame. The SS also starts a time associated with the ranging code. In response to all received ranging opportunities, the BS broadcasts an acknowledgement (ACK) in a subsequent downlink frame. The ACK comprises a reception status message that indicates the decoding status of the ranging opportunities. With the novel fast feedback mechanism, when ranging collision or failure occurs, upon receiving the reception status report, the SS will proceed with the next round of contention without continuing wait for the entire timeout period. As a result, the total latency due to the ranging collision or failure is reduced.

摘要： In a wireless OFDM multi-carrier communication system, a mobile station obtains measurement result of a first received signal strength indication (RSSI) of a first preamble signal transmitted from a base station over a first radio frequency (RF) carrier. The mobile station also obtains signal offset information between the first RF carrier and a second RF carrier of the base station. In response to the measurement result and the signal offset information, the mobile station estimates a second RSSI of a second preamble signal transmitted by the base station over the second RF carrier without performing scanning over the second RF carrier. In one novel aspect, the mobile station identifies a carrier group containing multiple carriers that belong to the same base station. Measurement optimization, initial cell selection and cell reselection optimization, report reduction, and other carrier group based optimization can be achieved in the multi-carrier system based on identified carrier group.
