20120044846 | OPERATION OF A TELECOMMUNICATIONS SYSTEM - A method of operating a mobile telecommunications system having a base station, a plurality of users and a plurality of spectral resource blocks, some of which are not allocated to users. The method includes, (a) for each user, assigning a score to each resource block based on the energy efficiency with which the user can use the resource block, and determining which of the plurality of resource blocks is favored, i.e. has a score indicating that it will be the most energy efficient for the user. For each user, either (b) if the user's favored resource block is not allocated, and is not favored by any other user, that resource block is allocated to that user; or (c) in the event that the same resource block is favored by more than one user, it is allocated to the user who will use it with the greatest energy efficiency. | 02-23-2012 |
20120134433 | METHOD AND SYSTEM OF ENHANCED PERFORMANCE IN COMMUNICATION SYSTEMS - A method of spatial modulation to identify a transmitter within a transmission array, wherein the transmitter has a unique bit sequence and defines a spatial component indicative of relative location is disclosed, comprising the following steps: receiving transmitted bits from the transmission array and identifying the unique bit sequence, the spatial component and a signal components; encoding the unique bit sequence and the spatial component by grouping the transmitters into transmitter groups such that the transmitters in each group have a maximum spatial separation relative to one another to thereby form an encoded signal; decoding the encoded signal to identify the transmitter from which the transmitted bits were transmitted by determining the transmitter location from the or each group. The method preferably comprises trellis coded spatial modulation. Also, a corresponding system is disclosed, the system comprising an encoder for encoding the unique bit sequence and the spatial component identified and received from the transmission array, the encoding including grouping the transmitters into transmitter groups such that the transmitters in each group have a maximum spatial separation relative to one another to thereby form an encoded signal.
