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.

摘要： A method of power management for a mobile station in a multi-carrier wireless network is provided. A primary connection between the mobile station and a serving base station is first established by performing initial ranging over a primary radio frequency (RF) carrier. A secondary connection between the mobile station and the base station is then established by performing periodic ranging over a secondary RF carrier. To achieve efficient power management, the mobile station performs Open Loop Power Control and obtains long-term link measurement (CSI) of the primary carrier. The mobile station then adjusts carrier-specific parameters based on the primary carrier CSI. For RF carriers that convey on-going data traffic, Close Loop Power Control is updated per RF carrier. When the mobile station enters sleep mode operation, it receives traffic indication messages on the primary RF carrier and then dynamically wakes up one or more corresponding RF carriers for data reception.

摘要： Two preamble partition schemes are provided for flexible network deployment and efficient utilization of limited cell identification resources in a wireless network. In a soft partition scheme, the entire preamble sequences are partitioned into several configurable non-overlapping subsets, and each subset is associated with a corresponding cell type. In a hybrid partition scheme, a combination of fixed and configurable subsets is used for preamble partition. The partitioning information is carried in a broadcasting channel broadcasted from base stations to mobile stations. In one embodiment, after a mobile station performs scanning and synchronization with a first base station, it derives the cell type of the first base station from cell identification and partitioning information. The mobile station completes ranging and network entry with the first base station if the cell type is preferred, and starts to perform scanning and synchronization with a second base station if the cell type is non-preferred.

摘要： A Femto Base Station (FBS) includes a communication functionality and a reliability functionality. A control entity within the reliability functionality detects an FBS reliability compromising event (for example, an unscheduled loss of external power to the FBS). As a result of detecting the FBS reliability compromising event, the control entity sends a message (an “FBS Reliability Compromising Event Compensation Message” or “FBSRCECM”) to the communication functionality. The FBSRCECM initiates an action that compensates for the FBS reliability compromising event. In many examples, the action is the initiating of a handover from the FBS to another base station. The reliability functionality typically includes a rechargeable battery that powers the FBS for a time until the handover is completed gracefully. By performing a graceful handover, cellular network reliability is improved as compared to situations in which a conventional FBS simply stops working and connections handled by the conventional FBS are broken.

摘要： Methods and systems for providing fast handoff in WLAN-like communications system construct a caching candidate set based upon a weighted handoff tendency coefficient. The weighted handoff tendency coefficient is based upon the handoff matrix and the weighting factor. The handoff matrix is an adaptive two-dimensional array that provides a list of nearby access points relative to a mobile station and the weighting factor is a value that prioritizes the nearby access points based upon a signal quality indication. A home access point, once it is triggered to initialize proactive caching, provides the caching candidate set with registration data of the mobile station before a transfer of a connection between the home access point and one of the access points on the caching candidate set.

摘要： This invention provides a method for power-efficient transmission supporting integrated service over WLAN. The said invention combines the polling-based and the contention-based mechanisms, named on-demand polling (ODP). In the ODP scheme, a voice station is in the polling list when it is in the active mode. During the idle mode, it is configured to operate in the sleep mode for saving power. Also, it adopts the contention-based mechanism to join the list again while returning from the idle mode. On the other hand, the data station adopts the contention-based mechanism to transmit its packets over WLAN. In addition, to achieve service differentiation, the said invention also employs a prioritized access probability for voice over data services. Simulation results show that the said invention can reduce the power consumption for voice stations and enhance the throughput for data stations.

摘要： Signaling methods for UE-specific downlink control channels in OFDMA systems are provided. In a first method, a dynamic downlink signaling in cell-specific radio resources is used to signal UE-specific downlink control channel in UE-specific radio resources. In LTE, a specific DCI format in PDCCH is used to dynamically signal the UE-specific downlink control channel X-PDCCH that resides in legacy PDSCH region. In a second method, a semi-static higher-layer signaling is used to signal UE-specific downlink control channel in UE-specific radio resources. In LTE, RRC signaling is used to semi-statically signal the UE-specific downlink control channel X-PDCCH that resides in legacy PDSCH region. By using UE-specific downlink control channels, significant control overhead reduction can be achieved.

摘要： A method of multi-set RRC signaling for ap-SRS configuration is provided to enhance ap-SRS flexibility. An eNB transmits a plurality of sets of UE-specific SRS parameters to a UE via upper layer messaging in a multi-carrier wireless communication system. The eNB also determines triggering information of a selected set of UE-specific SRS parameters and an indicated carrier for the UE. The eNB then transmits an uplink or downlink grant over a primary carrier, the grant comprises triggering information for the UE to send an ap-SRS over the indicated carrier using the selected set of UE-specific SRS parameters. In one embodiment of joint signaling, the plurality of sets of UE-specific SRS parameters are signaled together in a single RRC transmission. In another embodiment of separate signaling, each set of UE-specific SRS parameters is signaled independently.

摘要： A channel interleaver comprises a novel constellation-based permutation module. The channel interleaver first receives a plurality of sets of encoded bits generated from an FEC encoder. The encoded bits are distributed into multiple subblocks and each subblock comprises a plurality of adjacent bits. A subblock interleaver interleaves each subblock and outputs a plurality of interleaved bits. The constellation-based permutation module rearranges the interleaved bits and outputs a plurality of rearranged bits. The rearranged bits are supplied to a symbol mapper such that a plurality of consecutively encoded bits in the same set of the encoded bits generated from the FEC encoder is prevented to be mapped onto the same level of bit reliability of a modulation symbol. In addition, the plurality of adjacent bits of each subblock is also prevented to be mapped onto the same level of bit reliability to achieve constellation diversity and to improve decoding performance.
