PROBLEM TO BE SOLVED: To provide a method and apparatus for facilitating a hand-in to a femto cell.SOLUTION: An identifier is assigned to a femto cell in which the identifier is based on a scrambling parameter and a timing parameter. A relationship between the identifier and the femto cell is then communicated. In another embodiment, a user equipment report is received, which includes attributes related to a signal broadcast by a femto cell. An identifier associated with the femto cell is ascertained from an attribute included in the report. The femto cell is then identified on the basis of the identifier. In a further embodiment, a timing parameter is received, and a scrambling parameter is set. A signal including the scrambling parameter is then broadcasted according to an offset related to the timing parameter.

PROBLEM TO BE SOLVED: To provide a data transmission/reception technique that achieves power savings for a wireless device and improves capacity for a wireless network.SOLUTION: The techniques utilize a Continuous Packet Connectivity (CPC) mode 240 comprised of multiple discontinuous transmission (DTX) modes 310, 312 and at least one discontinuous reception (DRX) mode 314. Each DTX mode 310, 312 is associated with different enabled uplink subframes usable for transmission from the wireless device to the network. Each DRX mode 314 is associated with different enabled downlink subframes usable by the network for transmission to the wireless device. The wireless device may send signaling and/or data on the enabled uplink subframes and may receive signaling and/or data on the enabled downlink subframes. The wireless device may power down during non-enabled subframes to conserve battery power. Mechanisms quickly transition between the DTX modes 310, 312 and DRX mode 314.

PROBLEM TO BE SOLVED: To provide a method and device for mobile station hashing to a frequency of communication system. SOLUTION: Two-level hashing is used in which a mobile station is assigned to a frequency band and then assigned to a specific frequency within the frequency band. In one embodiment, a weight is assigned to a frequency, and the mobile station can be hashed to the weighted frequency. Weighting allows a non-uniform distribution of mobile stations in a frequency for optimizing system operation parameters. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate dynamic load balancing in a communications network.SOLUTION: One or more mobile devices can send random access preambles on an uplink frequency paired to a downlink frequency employed to connect the one or more mobile devices to a base station. The base station can determine if an uplink frequency load imbalance exists based upon the random access preambles. The base station can transmit an indicator on an acquisition indicator channel to at least one mobile device. The indicator includes a command to transition to a new uplink frequency. The mobile device can switch uplink frequencies in response to the command.
Abstract:
PROBLEM TO BE SOLVED: To provide a method of enabling user terminal (UT) access to wireless networks having disparate types of base stations (BSs).SOLUTION: A distinct identifier (ID) is reserved for a particular type of network access point. The distinct ID is broadcasted by such access points, identifying the access point type. In some aspects, the distinct ID is unicast to a terminal that is within a predetermined region of the network. Thus, at least within such region, the terminal can be directed to search for or handoff to a preferred type of access point. In such aspects, by providing regional-specific access, the subject disclosure can significantly reduce overhead signaling outside a home region where a home or preferred access point is expected to be found.
Abstract:
PROBLEM TO BE SOLVED: To provide a method and a system for code coupling data from different base stations in a communication system. SOLUTION: An encoder adds redundancy to the block of an information bit transmitted via different stations in a communication system. Through the redundancy, decoding becomes possible of a symbol received from an information block that is not completely encoded. Symbols received from different stations are combined before decoding. This communication relates to broadcasting or multi-cast communication in a wired or a wireless communication system, and is known as point-to-multipoint communication. COPYRIGHT: (C)2011,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide techniques to support operation of user equipment (UE) in a compressed mode and a CPC mode.SOLUTION: The UE obtains assignment of enabled subframes for the CPC mode and assignment of transmission gaps for the compressed mode. The transmission gaps are aligned with idle times between the enabled subframes. The UE exchanges data during enabled subframes not overlapping the transmission gaps and skips data exchanges during enabled subframes overlapping the transmission gaps. The UE makes cell measurement during the transmission gaps. The UE obtains enabled subframes and skipped subframes, exchanges data during enabled subframes not corresponding to the skipped subframes, and skips data exchanges during the skipped subframes. The UE receives orders on a shared control channel to quickly enable and disable the compressed mode.
Abstract:
PROBLEM TO BE SOLVED: To provide techniques for managing operation of user equipment (UE) in a multi-carrier system.SOLUTION: A system may support two or more carriers on the downlink and one or more carriers on the uplink. One carrier on each link may be designated as an anchor carrier. In an aspect, a lower layer order (e.g., an HS-SCCH order) may be used to make the UE transition between single-carrier and multi-carrier operation. In another aspect, the UE may have the same discontinuous reception (DRX) configuration for all downlink carriers and/or the same discontinuous transmission (DTX) configuration for all uplink carriers. In yet another aspect, HS-SCCH-less operation may be restricted to the anchor carrier.
