摘要： Disclosed is an electrode structure for a drift tube in IMS comprising a ring electrode, for each of two surfaces of the ring electrode, at least a part adjacent to the inner radius is formed into a cone, and the angles formed between the cones and the axis of the ring electrode are different from each other. The electrode structure of the present invention can alleviate, even eliminate, the accumulation of space charges in the drift tube. Such structure is particularly suitable when the electric field in the drift tube is low in strength or a great number of ions pass through. Meanwhile, the structure allows a significant decrease in the size of the outer radius of the electrode, while the inner radius remains constant. In this way, it is possible to effectively reduce the outline size of the drift tube and thus make the IMS compact.

摘要： Techniques for sending low reuse preambles in a wireless network are described. In an aspect, a base station may send a low reuse preamble on reserved frequency resources to allow terminals to detect the base station even in the presence of strong interfering base stations. The base station may generate the low reuse preamble to include a pilot portion and a data portion. The base station may determine frequency resources reserved for sending low reuse preambles by base stations. The base station may then send the low reuse preamble on the reserved frequency resources, e.g., at a pseudo-randomly selected time. A terminal may detect for low reuse preambles sent by the base stations on the reserved frequency resources. The terminal may recover information for a base station from a detected low reuse preamble.

摘要： Techniques for sending signaling messages with beacon signals in a wireless communication network are described. In one design, a transmitter station may map a signaling message (e.g., a reduce interference request) to multiple code symbols. The transmitter station may select multiple resource elements from among a plurality of resource elements based on the multiple code symbols. In one design, each code symbol may be sent across frequency by selecting one of multiple subcarriers in one symbol period. In another design, each code symbol may be sent across time by selecting one of multiple symbol periods on one subcarrier. The transmitter station may generate a beacon signal having transmit power on the selected resource elements and no transmit power on remaining resource elements. The transmitter station may send the beacon signal to at least one receiver station.

摘要： Methods and apparatuses are provided that include selecting resources for assigning to a device to mitigate relay self-interference when also communicating with a base station. The resources can be selected based on one or more factors, such as based on resources that are negotiated with the base station, or based on resources indicated as not desired for allocation from the base station, etc. In other examples, reference signals and control data can be communicated such as to mitigate relay self-interference as well.

摘要： The described aspects include methods and apparatus for aggregating carriers over a backhaul link between a relay and an evolved Node B (eNB). A first set of subframes of at least a first carrier of a plurality of carriers configured for communicating with an eNB over a backhaul link can be determined. A second set of subframes of at least a second carrier of the plurality of carriers configured for backhaul link communications is also determined, wherein the second set of subframes are different from the first set of subframes. Data received over a plurality of access link carriers can then be communicated to the eNB over the first carrier and the second carrier based at least on the first set of subframes and the second set of subframes.

摘要： Techniques for supporting relay communication with subframe staggering are described. For subframe staggering, subframes of different relays are staggered from one another, which can increase the number of potential backhaul subframes. In one design, a first relay determines its access subframes and backhaul subframes, which correspond to different non-overlapping subsets of the subframes of the first relay. The first relay communicates with at least one UE during the access subframes and communicates with a base station during the backhaul subframes. The subframes of the first relay are offset from the subframes of a second relay communicating with the base station. In one design, the access subframes of the first relay includes all subframes with either even or odd indices, which can support data transmission with HARQ. In one design, at least one access subframe corresponds to at least one reserved subframe having reduced transmit power from the base station.
