    摘要: A method of managing multiple timing advance (TA) groups, maintaining multiple TA timers, and performing UL synchronization in a multi-carrier wireless system is provided. When a new component carrier (CC) is configured, it is assigned to a TA group having a TA group identifier. The TA groups are managed statically or dynamically. The TA group identifier is used to uniquely identify the TA group in the operations of uplink (UL) timing synchronization. Multiple TA timers are assigned to multiple TA groups. The TA timers may have different values for different TA group. Different embodiments of UL timing adjustments for multiple TA groups are provided.

    摘要: A method of obtaining system frame number for handover is provided. A UE receives a handover command from a serving base station in a serving cell. The UE performs downlink synchronization with a target base station. Upon synchronization, the UE determines a radio frame boundary of a target cell. The UE then obtains a system frame number of the target cell based on the radio frame boundary. The UE performs a handover procedure with the target cell by transmitting a RACH preamble to the target base station. The RACH preamble is transmitted over a PRACH resource determined from the system frame number without reading SFN information from a PBCH/BCH broadcasted from the target base station. Finally, the UE establishes data connection with the target base station. Handover interruption time is reduced by obtaining SFN before PBCH reading and decoding.

    摘要: A movable jaw quick release apparatus of a vice comprises a tooth base, a movable jaw and two restriction elements. The tooth base is formed with two inclined guide grooves, each of which has a first inclined surface, a second inclined surface and a bottom surface. The left and the right side surfaces of the movable jaw are formed with a through hole respectively. Each restriction element penetrates one of the through holes and moves between a first position and a second position along one of the inclined guide groove As the movable jaw generates vibration forces, each restriction element transfers the vibration forces to the tooth base, therefore, the movable jaw do not move upwardly and shake toward a work piece and reduce its clamping force for the work piece.

    摘要: Various methods for wireless communication in a device with co-existed/co-located radios are provided. Multiple communication radio transceivers are co-existed/co-located in a user equipment (UE) having in-device coexistence (IDC) capability, which may result in IDC interference. For example, the UE is equipped with both LTE radio and some ISM band applications such as WiFi and Bluetooth modules. In a first method, the network identifies IDC capability by UE identification (e.g., UE ID). In a second method, the UE intentionally performs cell selection or reselection to cells in non-ISM frequency bands. In a third method, the UE signals the existence of ISM band applications via capability negotiation. In a fourth method, the UE signals the activation of ISM band applications by signaling messages (e.g., RRC message or MAC CE). Under the various methods, the UE and its serving eNB can apply FDM or TDM solutions to mitigate the IDC interference.

    摘要: An enhanced access control method is proposed for machine-type communications (MTC) in a 3GPP LTE-Advanced network. An MTC device is configured for enhanced access barring (EAB). When the MTC device attempts access to the network, the NAS layer checks whether EAB is applicable for the MTC device. If yes, then the NAS layer forwards EAB configuration to the AS layer for further EAB control. Based on the EAB configuration, a base station broadcasts EAB information to UEs via system information block. The EAB information indicates whether barring is applied to a number of EAB categories and a number of access classes. Based on the EAB information, the MTC devices performs EAB for access attempt to RRC. If access is not barred under EAB, then the MTC device further performs ACB for access attempt to RRC.

    摘要: Methods for enhanced heterogeneous network mobility are proposed. In a first novel aspect, the cell size of a target cell is considered when determining the TTT value. In one embodiment, pico-specific Time-to-Trigger (TTT) value is configured. When the target cell to be measured is a picocell, pico-specific TTT value is applied. In a second novel aspect, precise mobility state estimation (MSE) is achieved by considering the effect of cell size. In one embodiment, when counting cell changes, a cell change to/from a small cell would be counted to lesser extent than a cell change between large cells. UE uses effective parameters for measurement evaluation, by applying better speed state estimation with speed scaling and by applying parameter differentiation that can be dependent on cell size.

    摘要: Enhanced paging mechanisms are proposed for Machine Type Communication (MTC) devices in 3GPP networks. First, adaptive paging is proposed to adaptively allocate extra paging occasions for MTC devices with no extra procedure or power consumption on normal UEs. Second, group paging is proposed to simultaneously page a plurality of MTC devices with one paging. Group paging is controlled in different levels for optimized signaling and easier management. In one embodiment, group broadcasting and group release are used. Third, paging with response policy is proposed to pre-define or dynamically configure paging response policies for MTC devices.

    摘要: A method of providing Local IP Access (LIPA) indication is proposed. In one novel aspect, an enhanced cell selection method is proposed using LIPA capability information. Based on LIPA capability related information, a UE is able to prioritize LIPA-capable cells and establish a corresponding packet data network (PDN) connection accordingly. In a first embodiment, LIPA information is statically configured in the UE. In a second embodiment, LIPA information is informed to the UE via broadcasting or unicasting Radio Resource Control (RRC) signaling.
