Abstract: An interference cancellation method, data sending method, apparatus, user equipment and base station in a Long Term Evolution system are disclosed. The interference cancellation method includes: obtaining downlink cell-specific power ratio information of a specific cell; performing channel estimation based on a downlink cell-specific reference signal (CRS) of the specific cell, to obtain a channel estimation matrix of a specific physical channel, signal, or message of the specific cell; compensating the channel estimation matrix by using the downlink cell-specific power ratio information; and canceling, in an original signal that is received from a target cell and is interfered by the specific cell, interference caused by the specific cell in a received signal from a specific physical channel, signal, or message.

Abstract: Techniques for monitoring guest domains configured with alternate I/O domains are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for monitoring guest domains configured with alternate Input/Output (I/O) domains comprising, installing cluster services in a control domain, installing cluster services in one or more alternate I/O domains, configuring, using at least one computer processor, an alternate service group to monitor services from multiple I/O domains, and configuring a logical domain service group, wherein the logical domain service group manages a guest domain which receives I/O services from either the control domain or the at least one alternate I/O domain which are monitored via the alternate I/O service group.

Abstract: A method and nodes for providing adaptive segmentation in a higher protocol layer interacting with a lower protocol layer. An adaptable segmentation limit, defining a threshold of a largest Protocol Data Unit (PDU) that is to be submitted to a lower protocol layer, is deployed at a higher protocol layer interacting with the lower protocol layer. For each Service Data Unit (SDU) arriving at the higher protocol layer, it is determined if the respective SDU can fit into the segmentation limit or not. Each SDU that do not fit into the segmentation limit is segmented into PDUs which are smaller than or equal to the segmentation limit, while no segmentation is performed on SDUs that fit into the segmentation limit.

Abstract: A system and method for assembling a single data stream from multiple instances of that data stream is described. Data transmitted from a cellular telephone subscriber unit is received by a set of base transceiver stations. Each base transceiver station performs various error detection procedures on segments of the data referred to as frames. These error detection procedures may include CRC check sum verification, Yamamoto metric calculation, re-encoded signal error rate calculation, or a combination thereof. The results of these error detection procedures are placed into a frame quality metric. The frame, frame quality metric, a time stamp and an address are placed into a packet that is transmitted from each base transceiver station to a base station controller which matches packets attempting to transmit the same information using the time stamp and selects one frame from the packets for further processing based on the associated frame quality metric.
