Abstract: In a cellular communication system where two mobile stations are located within or near to a cell associated with a base station, one or more relay stations with good radio link quality relative to the two mobiles may be used to build a local forwarding communication link between the mobile stations using the one or more relay stations which avoids downlink/uplink transmission with the base station. The relay station(s) is(are) selected based on an association between two mobile stations and the relay station(s).

Abstract: A method is provided, in a wireless communications network comprising a source node, a destination node and at least one relay node, of selecting spatial subchannels for use. The method comprising the steps of: spatially decomposing channels into spatial subchannels; and selecting a subset of the subchannels for use that at least approximately maximises predicted throughput rate.

Abstract: The present invention relates to a method for preventing or treating of cartilage related diseases, such as osteoarthritis, rheumatoid arthritis, articular cartilage damage, multiple chondritis, osteochondrosis, etc., which comprises administering an effective amount of calcium L-threonate to a subject in need of such prevention or treatment. It had been demonstrated by experiments that calcium L-threonate could improve significantly the positive expression percentage of collagen I mRNA in the chondrocyte and osteoblast, improved significantly the positive expression percentage of articular cartilage and epiphyseal cartilage, facilitated the growth of chondrocyte, increased the quantity of bone collagen, and promoted the formation of bone and cartilage matrix and the synthesis of proteoglycan. It could also promote the formation of bone nourishing blood vessels and improve the microcirculation of bone.
