Abstract: A user device receives packets from a base station. The user device may invoke decoding while the packet is still being received, based on the incomplete contents of a given packet. This “partial packet decoding” relies on the fact that the underlying information in the packet is encoded with redundancy (code rate less than one). If link quality is poor, the partial packet decoding is likely to be unsuccessful, i.e., to fail in its attempt to recover the underlying information. To avoid waste of power, the user device may be configured to apply one or more tests of link quality prior to invoking the partial packet decoding on a current packet.

In response to the received downlink communication, an acknowledgement message is received/transmitted in an uplink time slot a fixed integer number of uplink time slots after transmission/reception of the received downlink communication. The uplink and downlink time slots are staggered by substantially a half of a time slot.

Abstract: A radio base station (RBS), such as an eNodeB, for supporting TTI bundling transmissions from a User Equipment (UE) using is provided. The RBS is arranged for toggling a TTI bundling mode of the UE by transmitting a first signal (531) to the UE, and for receiving a second signal (538) from the UE indicating that the UE has toggled its TTI bundling mode. During the transition state of the switching procedure, between transmitting the first signal and receiving the second signal, all transmissions from the UE are scheduled as TTI bundling transmissions (532, 536), transmissions received from the UE are decoded at time instances for both normal transmissions (511) and TTI bundling transmissions (512), and feedback information is transmitted to the UE at time instances for both normal transmissions (534) and TTI bundling transmissions (535). In this way, all packets received at the RBS may be decoded correctly and retransmission of packets by the UE is avoided. Further, a corresponding method is provided.

Abstract: A discontinuous change in a transmission timing in a time domain, which is caused by a transmission timing adjustment processing of an OFDMA uplink or the like, brings about a discontinuous rotation of a signal phase in a frequency domain, resulting in reduced communication quality. A wireless communication system of the present invention allows the signal phase of the frequency domain in a receiving station to be continuous before and after the timing adjustment processings by controlling a signal sequence in a transmission signal after conversion in the time domain in synchronization with the timing adjustment processing.

Abstract: Transfer destination of a packet originating from a virtual machine is controlled so as to allow a capture device arranged in a communication network to capture a packet that is transferred using a communication tunnel. A first server acquires a first packet originating from a source virtual machine being operated by the first server, encapsulates the first packet by adding source and destination addresses. The first server further adds a transfer-destination address to the encapsulated first packet to generate a second packet when the first packet is determined to be a target packet to be captured by the capture device. Then, the first server transmits the second packet including the transfer-destination address to the second server using the communication tunnel while the second packet including the first packet is transferred to the transfer-destination address.

Abstract: When an operating system process evaluates a rule for an operation being attempted on a logical network port, the operating system process determines whether the target logical port falls within a range of logical ports, and then determines whether the operation is associated with a permitted domain of the range of logical ports. If the operation is a bind operation, then the process attempting to bind to the target port will be allowed to bind if the target port falls within the range and the operation/process is associated with a permitted domain. Otherwise, the binding operation will not be allowed to proceed.

Abstract: A communication system utilizes at least one digital subscriber line access multiplexer (DSLAM) at an intermediate point between a network facility and one or more customer premises. Initially, as few as one DSLAM, may be implemented at the intermediate point, but the system can be expanded to include any number of DSLAMs at the intermediate point. Any of the DSLAMs at the intermediate point can be selectively upgraded at any time to a vectoring solution as may be desired. The use of such DSLAMs provides the network service provider with flexibility in implementing and maintaining the network.

Abstract: A method and apparatus are provided for identifying a cell and a sub-frame by detecting a part of a secondary synchronization signal including a sequence of N OFDM symbols. For each OFDM symbol, the method obtains a set of metrics, each metric being associated with a predetermined combination of a cell identifier and a sub-frame alignment (CID/SF). For each metric, the method counts the number of times a metric exceeds a first predetermined threshold, delivering a summed value, and applies an M of N criterion to the summed value, delivering a ratio value. The ratios values are analyzed in order to identify the cell and the sub-frame, corresponding to a cell identifier and a sub-frame alignment, associated to a particular ratio value among the ratios values, which exceeds a second predetermined threshold.
