Abstract: The present invention relates to a data transmitting method using a bandwidth request channel and a user terminal and a base station conducting the same. The present invention provides a communication method by a user terminal which transmits data to a base station via a bandwidth request channel, including: generating a preamble for bandwidth request; determining whether a message for the bandwidth request is generated; generating a first signal value to be operated with the preamble when it is determined that the message is generated and generating a second signal value to be operated with the preamble when it is determined that the message is not generated; operating the preamble with the generated first signal value or second signal value; and transmitting a signal including the operated preamble to the base station, thereby reducing overhead occurring when the bandwidth request information is demodulated.

Abstract: Wireless devices, methods, and computer readable media for synchronization in a wireless local-area network. A method on a wireless communication device may include tuning to a first subchannel based on a schedule received from an access point (AP) the schedule to indicate that the HEW device is assigned to the first subchannel. The method may further include determining a target beacon receive time and tuning to a second subchannel to receive the target beacon at the target beacon receive time. The method may further include receiving the target beacon on the second subchannel and tuning back to the first subchannel. A method on an AP for synchronization may include transmitting information that indicates a target beacon receive time on a subchannel. The method may include not transmitting to a wireless communication device operating on a second subchannel for a period of time before the target beacon receive time, and transmitting a target beacon on a first subchannel at the target beacon receive time.

Abstract: One embodiment provides a system that facilitates forwarding of packets with variable length names. During operation, the system receives a packet with a hierarchically structured variable length identifier (HSVLI) which comprises contiguous name components ordered from a most general level to a most specific level. The system performs a longest prefix match lookup by selecting an entry from a first data structure of entries. The entries indicate a name component, forwarding information for the name component, and a plurality of entry identifiers that chain an entry to another entry. If a size of the name component is less than or equal to a predetermined threshold, the system selects an entry based on the name component. If the size is greater, the system selects an entry based on a compressed key which can be a hash of the name component. The system also resolves collisions associated with the selected entry.

The soft buffer management circuitry has input circuitry for receiving information relating to an aggregated carrier comprising a plurality, NDU/ULcells, of configured component carriers. Control circuitry is provided for prioritizing allocation of storage in the soft buffer depending on a carrier index value indicating a prioritization of a corresponding component carrier relative to the other configured component carriers. The buffer is partitioned into a number min (NC, NDL/ULcells) partitions, where NC gives a number of carriers for which soft buffer storage is to be prioritized. A UE comprising the soft buffer management circuitry and a soft buffer management method are also provided.
Abstract: A method for a communication apparatus to align a frame boundary with a cell. A first time at which a predetermined synchronization signal is supposed to be received is determined after knowing a timing of the cell. The predetermined synchronization signal is a primary synchronization signal or a secondary synchronization signal. A second time at which the predetermined synchronization signal is actually received is determined. A first offset between the first time and the second time is determined. A timing of a local time base utilized by the communication apparatus according to the first offset is adjusted such that a frame boundary of the local time base and a frame boundary of the cell are aligned.

Abstract: The invention relates to a method and an arrangement in a transmitting node (560) for enabling a receiving node (540) to perform measurements on interference caused by transmissions from at least one transmission point (510, 520, 530) controlled by the transmitting node (560) on receptions at the receiving node (540). The transmitting and receiving nodes (560, 540) are comprised in a wireless communications system (500, 600, 700). The transmitting node determines (910) an interference measurement resource, IMR, comprising a set of Time-Frequency Resource Elements, TFREs, upon which the transmitting node is expected to transmit interference. The transmitting node then transmits (930) at least one interfering signal on said IMR as said interference.
