Method, user equipment and radio base station for random access in a cellular telecommunications system technical field of the invention
The present invention relates to a random access process in a cellular communications system and to a user equipment (UE) and a NodeB adapted for performing the process. A problem with the random access is that the time slot for receiving a random access request (RA-request) has a long unused guard portion. When the UE transmits the RA-request, the distance to the receiving NodeB is unknown, and the purpose of the guard portion is to accommodate for propagation delay. The disadvantage is the inefficient use of the random access channel which results in long delays for UEs to access the network. The present invention solves the problem with a method in which the UE position is determined and the distance and propagation delay between the UE and NodeB is calculated before the transmission of the RA-request, and the timing of the transmission is advanced by the propagation delay. |

Event service for local client applications through local server
In server/client architectures, the server application and client applications are often developed in different languages and execute in different environments specialized for the different contexts of each application (e.g., low-level, performant, platform-specialized, and stateless instructions on the server, and high-level, flexible, platform-agnostic, and stateful languages on the client) and are often executed on different devices. Convergence of these environments (e.g., server-side JavaScript using Node.js) enables the provision of a server that services client applications executing on the same device. The local server may monitor local events occurring on the device, and may execute one or more server scripts associated with particular local events on behalf of local clients subscribing to the local event (e.g., via a subscription model). These techniques may enable development of local event services in the same language and environment as client applications, and the use of server-side code in the provision of local event service. |

Method and apparatus for precomputation based MIMO decoder
Spatial Multiplexing (SM) with Multiple Input Multiple Output (MIMO) is used in many communication systems for providing high data rates. While SM-MIMO is a powerful technique for increasing the data rate and bandwidth efficiency, the decoders for SM-MIMO are highly complex. The complexity grows exponentially for optimum decoders as the number of multiplexed layers in SM-MIMO increases. Many reduced complexity suboptimal methods are used in practice that have close to optimum performance but they remain highly complex causing high power consumption which is not desirable for battery operated client terminals. Due to the parallel architecture of many of the SM-MIMO decoders, they involve computations that may eventually turn out to be redundant. A method and apparatus may include identifying and eliminating potentially redundant computations in SM-MIMO decoders based on the technique referred herein as precomputation. The removal of redundant computations enables reduced power consumption for SM-MIMO decoders. |

Encoding and decoding using constrained interleaving
Serially-concatenated codes are formed in accordance with the present invention using a constrained interleaver. The constrained interleaver cause the minimum distance of the serial concatenated code to increase above the minimum distance of the inner code alone by adding a constraint that forces some or all of the distance of the outer code onto the serially-concatenated code. This allows the serially-concatenated code to be jointly optimized in terms of both minimum distance and error coefficient to provide significant performance advantages. These performance advantages allow a noise margin target to be achieved using simpler component codes and a much shorter interleaver than was needed when using prior art codes such as Turbo codes. Decoders are also provided. Both encoding and decoding complexity can be lowered, and interleavers can be made much shorter, thereby shortening the block lengths needed in receiver elements such as equalizers and other decision-directed loops. Also, other advantages are provided such as the elimination of a error floor present in prior art serially-concatenated codes. That allows the present invention to achieve much higher performance at lower error rates such as are needed in optical communication systems. |

Lithium-ion battery anode including core-shell heterostructure of silicon coated vertically aligned carbon nanofibers
A novel hybrid lithium-ion anode material based on coaxially coated Si shells on carbon nanofibers (CNF). The unique cup-stacking graphitic microstructure makes the CNFs an effective Li+ intercalation medium. Highly reversible Li+ intercalation and extraction were observed at high power rates. More importantly, the highly conductive and mechanically stable CNF core optionally supports a coaxially coated amorphous Si shell which has much higher theoretical specific capacity by forming fully lithiated alloy. Addition of surface effect dominant sites in close proximity to the intercalation medium results in a hybrid device that includes advantages of both batteries and capacitors. |
