摘要:
The present invention relates to a method for generating a reference signal, including: obtaining first control information, where the first control information indicates or includes cyclic shift related information which is used by a terminal belonging to a serving cell to send a reference signal; and sending the first control information to the terminal belonging to the serving cell, so that the terminal belonging to the serving cell generates the reference signal according to the cyclic shift related information which is indicated or included by the first control information and used by the terminal to send the reference signal, where a variation rule of a cyclic shift which the terminal belonging to the serving cell uses to generate the reference signal is the same as that of a cyclic shift which a terminal belonging to a coordinated cell uses to generate the reference signal.

Procedures and systems may be used for assigning data partitions to data-processing host computers, for example, to initially assign data partitions at the outset of a large data-processing job or during failover measures taken in response to a failed host in a share-nothing database management system (SN-DBMS). In one implementation, a method of managing exclusive access to a data partition within a database system assesses a first host and a second host that have exclusive access to a first and second data partition, respectively, within a database system. The method assigns exclusive access of the data partition to one of the first and second hosts based on factors that may include the processing powers of first and second the hosts, and on processing requirements (such as data quantity and data criticalness) for data on the first and second data partitions.

Double transformer balun for maximum PA (Power Amplifier) power. A novel approach is presented herein by which conversion from a differential signal to single-ended signal may be achieved using a double transformer balun design. The secondary coils of the double transformer balun also operate as a choke for the PA supply voltage. The secondary coils can operate as an RF (Radio Frequency) trap or choke to keep any AC (Alternating Current) signal components and to pass any DC (Direct Current) components. By using a double transformer balun design, relatively thinner tracks may be employed thereby ensuring a high degree of electromagnetic coupling efficiency and high performance. Also, these relatively thinner tracks consume a relatively small amount of space on the die. The double transformer balun design also includes a matching Z (impedance) block that is operable to match the Z of an antenna or line that the PA is driving.

Certain aspects of a method and system for mitigating effects of pulling in multiple phase locked loops in multi-standard systems may include selecting an input frequency range of operation at a voltage controlled oscillator based on a particular wireless band of operation in a system that handles a first wireless communication protocol and a second wireless communication protocol. An image rejection mixer may be enabled to generate an output signal for the particular wireless band of operation based on mixing a plurality of received signals within a selected frequency range. An in-phase (I) component and a quadrature (Q) component of the generated output signal may be generated by utilizing a RC-CR quadrature network.
