Mobile communication equipment comprises a power amplifier for amplifying a transmission signal and a feedback circuit for providing feedback to allow the above-described power amplifier to output a transmission-power set value. A circuit is placed on the poly sheet and embedded into the poly sheet, preferably with a heat resistant soft roller that presses the circuit into the poly without breaking the circuit. The mobile node transmits to a base station node an indication whether the mobile node supports mobile node specific cyclic prefixes. The pattern and indication may be sent in separate RRC messages, or if sent in one message there is a second indication sent in a second RRC message instructing the UE to terminate utilizing the pattern and indication for restricting its subframe measurements. The present invention also relates to preforms containing an upper section containing a powdered metal and a flux, and a lower section containing a protective material, such that the protective material contains, or generates upon being heated, a protective substance.
