Abstract: A mobile terminal is operated in a cellular communications system that comprises a base station operating in a time division duplex mode. The mobile terminal detects a downlink transmission from the base station and determines therefrom a future moment in time at which an end part of a downlink transmission just prior to a random access window will become detectable at the mobile terminal. An uplink random access transmission is begun at a moment in time that is before the future moment in time. The moment in time that is before the future moment in time can be a fixed amount of time before the future moment in time. If the mobile terminal is not near the edge of the cell, the base station may consequently receive only a partial uplink random access transmission, but this does not detrimentally affect performance.

Abstract: By adapting its search procedures, a user equipment in a mobile communication system can shorten the time needed to find a cell or public land mobile network. If a first cell in a first radio access technology has been found, the equipment can exclude one or more frequencies from a search for cells in a second radio access technology. Thus, time and power are not wasted searching for cells in the second radio access technology that cannot be found.

The arrangement of the first and second links provides increased leverage on the die assembly during the later stages of the compression stroke of the handle.

The connector defines at least one passage extending along the left upright frame, for example, so that another rack may be nested within a volume defined by the rack for reducing storage space requirements. The rack may have its connector oriented so that the rack has a substantially Z-shaped frame, a substantially X-shaped frame, a substantially U-shaped frame, a substantially V-shaped frame, or a substantially H-shaped frame, for example, when viewed from above. A lifting element may be provided on an upper portion of the rack for use with institutional and industrial lifting mechanisms. The lifting element may be mounted on the rack so as to avoid interference with another rack when the racks are nesting.

Abstract: The present invention relates to a blind detection of a received signal having at least one property, which initially is unknown to the receiver, however, limited to a finite set of alternatives ({p1, p2, . . . , pm}). According to the invention, the unknown property is automatically identified as follows. A respective quality measure (q1, q2, . . . , qm) is derived from the incoming signal (r(n)), which each represents a particular property in the finite set of alternatives ({p1, p2, . . . , pm}). The quality measures (q1, q2, . . . , qm) are obtained according to a procedure that involves a computationally efficient rejection of any unwanted signal components in the incoming signal (r(n)). Then, the quality measures (q1, q2, . . . , qm) are compared with each other in order to find a quality measure, which best fulfills a blind selection criterion. The quality measure (qi) thus obtained corresponds to the initially unknown property (pi).
