Abstract: A data compression/decompression methodology and system stores in a compression-side dictionary the data that has been transmitted and additionally applies to such data in the compression-side dictionary a status of being “invalid” for purposes of use as a reference in data compression until an acknowledgement signal has been received from the decompression side indicating that such data has been received. Once the compression side has received the acknowledgement signal indicating that the data in the form of a compressed data packet has been received on the decompression side, the status is changed from being “invalid” into being “valid”, i.e., into being usable as reference data for use in compressing further data elements in the data stream. Each data packet includes a stream index which is representative of the memory location in the compression-side dictionary where the first data element of the uncompressed data set of the data packet is stored.

Abstract: When IGMP packets are relayed to a predetermined router (L3SW), first and second L2SWs update their own snooping tables by snooping. Also, the first L2SW acquires a correspondence relation retained in the snooping table of the second L2SW through a control plane and registers it to the snooping table of the first L2SW. Then, when the first L2SW receives a multicast packet whose destination is a multicast group, the first L2SW extracts corresponding IP addresses based on its own snooping table and converts the multicast packet into unicast packets whose destinations are the IP addresses.

A single set of CoS queues can support a large number of devices, improving the efficiency of software-based queuing by reducing the number of queues and simplifying queue polling.

Abstract: Where first and second reference signals for a first and second communication system, respectively, are transmitted, resources that affect a reception apparatus compatible only with the first communication system can be minimized, and the throughput can be prevented from being deteriorated. As resources for a reference signal CSI-RS for LTE-A, last half symbols in a time direction of a resource unit RB/Sub-frame defined in a frequency-time domain are used, and the CSI-RS is allocated in a position up to the last two symbols or in the last symbol, or the like, of a particular RB/Sub-frame and transmitted when a reference signal 4RS for LTE is transmitted to a reception apparatus in addition to transmitting CSI-RS for LTE-A. The reception apparatus receives CSI-RS allocated in the last half symbol of RB/Sub-frame based on CSI-RS allocation information, measures channel quality by using this CSI-RS, and transmits and reports feedback information.
