摘要： A cage for the rollers in a roller bearing in which the roller axes (2) define an angle with the bearing axis (3) has two annular portions (4, 5) and intermediate cage bars (6) defining cage pockets (7). The bars are situated radially inside of the roller axes with respect to the bearing and a flange (8) for guiding the roller by contacting their ends is extending radially outwards from one of the annular portions (4). A protrusion (9) is arranged on the flange (8) in connection to each pocket (7) or insertion into a recess in the adjacent roller end and thereby keeping the roller in the cage pocket. A recess (10) in the other annular portion (5) opposite each protrusion (9) simplifies the snapping of the roller into its pocket in the cage.

摘要： The invention relates to a roller bearing having at least one row of rollers, in which the rollers are arranged at an angle to the bearing axis, an inner and an outer raceway for the rollers and a cast plastics cage for the rollers. The cage comprises two coaxial rings (1,2) and bars (3) extending between the rings, the rollers (4) being situated in pockets between the bars. In order to achieve a good positioning of the cage and a good guidance of the rollers when the cage is centered by contacting the rollers, the radial extension of the bars are greater than the radial width of the rings, whereby the bars have a portion (5) in connection to their middle part which portion extends radially inside or outside the pitch circle (6) of the rollers and contacts the rollers on a surface (7) so situated that a normal (8) through the contact of the roller surface with said surface (7) forms an angle (.alpha.) with a line (9) from the center of the bearing through the axis of the roller, the angle (.alpha.) being less than 60.degree.. Further, the cage has a portion at each end of the roller with a roller contact surface (10) so situated that a plane (11) through the contact surface (10) and the roller axis forms an angle (.beta.) with that plane (12) in which the roller is skewed when it is taking an oblique position in the cage pocket, the angle (.beta.) being less than 15.degree..

摘要： A spherical roller thrust bearing comprises two bearing rings rotatably guided by spherical roller elements for rotation about an axis. The roller elements are spaced circumferentially apart by a segmented retainer comprising separate retainer segments spaced apart in the circumferential direction. Each retainer segment includes opposite circumferentially facing surfaces engaging adjacent roller elements. Each surface includes at least one projection making point contact with a peripheral surface of a roller at a location whereby the force transmitted between the roller elements by the segments excludes a radially inward force component. The projections are located relative to the roller elements such that the segments tend to hang upon the roller elements.

摘要： A composite signal including a plurality of component signal streams is processed using QR-decomposition to detect symbols and calculate a decision metric for each of the signal streams (202). Soft serial interference cancellation is performed on the composite signal based on the symbols detected for different ones of the signal streams and a ranking of the signal streams (204). The symbols are re-detected and the decision metric re-calculated for each signal stream based on soft serial interference cancellation results (206). The different decision metric calculations for at least one of the signal streams are compared to determine whether symbol detection is more accurate with or without soft serial interference cancellation (208). The signal streams are decoded using symbols detected based on soft serial interference cancellation results when symbol detection is determined to be more accurate with soft serial interference cancellation (210). Otherwise, the streams are decoded based on the symbols detected using QR-decomposition (210).

摘要： The present invention relates to a system and a method for transmitting data between a first terminal and a communication network access point. The method may comprise the steps of defining a first set of scrambling codes and a second set of scrambling codes different from the first set of scrambling codes. Further, the method may comprise defining a first selection scheme for a first parameter. The method may still further comprise determining a current parameter value for the first parameter and evaluating the current parameter value on the basis of the first selection scheme and selecting a scrambling code from the first set of scrambling codes or the second set of scrambling codes based on the evaluation. Even further, the method may comprise packaging and transmitting data between the first terminal and the communication network access point using the selected scrambling codes.

Both the network node (28) and the wireless terminal (30) have multiple-input multiple-output (MIMO) capabilities. A MIMO-related order (90) is generated for inclusion in control signaling on a high speed downlink shared channel from the network node (28) to the wireless terminal (30). The MIMO-related order (90) is configured to modify channel quality indication (CQI) communications between the wireless terminal (30) and the base station (28) in view of MIMO capabilities of the wireless terminal (30). The method further comprises providing a channel quality indication (CQI) report (92) the wireless terminal (30) to the base station (28) in accordance with the order.

摘要： The present invention relates to a method and arrangements in a communication system for Multi User Multiple-Input-Multiple-Output (MU-MIMO) signaling via Multiple-Input-Multiple-Output (MIMO) antennas between a base station and one of a plurality of mobile terminals supporting both Single User and Multi User Multiple-Input-Multiple-Output (SU-MIMO and MU-MIMO) signaling modes. Switching between the modes is supported in the system and the modes have partly shared signaling. SU-MIMO mode signaling which is redundant, i.e. not needed, for MU-MIMO mode signaling is identified. Bits, i.e. data bits, of the identified redundant signaling is re-interpreted or re-defined to comprise signaling information associated with MU-MIMO mode. The signaling information associated with MU-MIMO mode is signaled to the mobile terminal by using the reinterpreted redundant bits.
