Abstract:
A method of allocating resources in a communication system which uses a plurality of sub-carriers arranged in a sequence of physical resource blocks wherein adjacent blocks of the sequence are arranged in groups. The method includes, in a base station, determining at least one virtual resource block for allocation to a mobile communications device, signalling data identifying each virtual resource block to the mobile communications device, and mapping each allocated virtual resource block, using predetermined mapping data, onto a plurality of spaced physical resource blocks to determine the physical resource blocks to be used for communications with the mobile communications device. At least part of the predetermined mapping data defines an equation for the location of a further physical resource block, relative to a first physical resource block.
Abstract:
A communications apparatus is described which is capable of auto-tuning a cell admission threshold value used to control admission into a communications network. The apparatus obtains an outage rate for one or more current calls at a node in the network, and also a blocking rate of the rate at which admission requests at the node are blocked and uses these rates to adjust a load threshold to be used in admission control decisions. The apparatus then controls admission of calls at the node in dependence on an estimated current load and the load threshold.
Abstract:
A method of signalling resource allocation data in a communication system which uses a plurality of sub-carriers arranged in a sequence of chunks includes receiving an allocation of the sub-carriers for each of a plurality of user devices, which received allocation identifies a type of allocation of the sub-carriers. The received allocations are processed, in dependence on the identified type of allocation, to determine, for each user device, data identifying a start chunk and an end chunk within the sequence of chunks, which depend upon the sub-carriers allocated to the user device. Different resource allocation data is generated for each of the user devices using the data identifying the corresponding start chunk and end chunk determined by the processing, the resource allocation data including type data identifying the type of allocation. The respective resource allocation data is signaled to each of the plurality of user devices.
Abstract:
A communications system is described in which user devices communicate with an associated base station. The user devices employ frequency hopping techniques to provide frequency diversity in their communications with the base station. Techniques are described for reducing collisions between the communications from the different user devices and for the efficient signalling of data defining the frequency hopping sequence to use. The inventions are particularly suitable for use in the uplink of the E-UTRA communications scheme.
Abstract:
A mobile communications system is proposed in which mobile communications devices are arranged to transmit signals to and to receive signals from a base station using one or a subset of available sub-bands, with the base station being configured to move the mobile communications devices between the sub-bands. An anchor sub-band is also provided on which idle mobile communications devices camp until they are moved to one or more other sub-bands in addition to or instead of the anchor sub-band.
Abstract:
A computer program product embodied on a computer readable medium may enable a computer processor to perform a method for generating a correlated investment. The method may include the steps of: discounting to present value one or more future liabilities at a discount rate of a bond that matures at the same time as the future liabilities; generating a correlated investment using an original investment amount and leverage funds; monitoring market information about a bond market using a computer; and recalibrating the correlated investment using the computer according to the market information, including: recommending at least one of buying or selling portions of the correlated investment as indicated by the market information. The future liabilities may be of a duration greater than the duration of the longest available bond issued by a sovereign.
