A communications apparatus capable of detecting a signal transmitted by another apparatus in a first band of spectrum is described. The apparatus identifies at least one second band of spectrum, different from the first band of spectrum, in which no signal is detected and then determines a noise characteristic for the at least one second band of spectrum. The determined noise characteristic may then be used by an energy detector operating in the first band of spectrum to ensure reliable detection of signals transmitted by the other apparatus.

Apparatus and method for signal detection

The invention concerns a method for optimizing the Transport Format Combination (TFC) selection procedure processed by a user equipment UE in an uplink communication in a mobile telecommunication network, wherein the TFC procedure during the current TTI (Time Transport Interval) at instant t+1 is performed in function of:

Optimized estimation of power for the transport format selection of a UMTS handset

A method of forming RLC blocks for contents synchronization within a mobile radio communications network includes providing a control element for each of a plurality of SDUs within each RLC block. Each control element comprises a header element arranged to precede its respective SDU. A network device provides the RLC blocks and such blocks as having such a structure.
