摘要:
A wireless communication system uses a multiple-input multiple-output (MIMO) antenna in the transceiver mode. The system includes the technical features of a stage in which m bits of a first set of information is transmitted for a first pre-coding matrix (where m is an integer greater than 1), and a stage in which n bits of a second set of information is transmitted for a second pre-coding matrix (where n is an integer greater than 1 but less than n).

The addition of thermal conduits by bonding bond wires to bond pads either in a wire loop configuration or a pillar configuration can improve thermal dissipation of a fabricated die. The thermal conduits can be added as part of the normal packaging process of a semiconductor die and are electrically decoupled from the circuitry fabricated on the fabricated die. In an alternative, a dummy die is affixed to the fabricated die and the thermal conduits are affixed to the dummy die. Additionally, thermal conduits can be used in conjunction with a heat spreader.

The present invention discloses a coronary artery vascular stent with drug carrying slots (2), comprising a plurality of main supporting unit rings (1,8) and connecting rods (4,6). Said main supporting unit rings comprise a plurality of unit waves. There are drug carrying slots (2) at the outer surface of the rods of said unit waves, characterized in that the total slot length of the drug carrying slots (2) is 60%-75% of the total wave rod length of the main supporting unit rings (1,8).
摘要:
A method for transmitting/receiving feedback information in a multi-antenna system using a closed-loop scheme supporting multiple users, and a feedback system supporting the same. Multiple feedback protocol scenarios are predefined on the basis of communication environments affecting feedback information configurations. The feedback information is transmitted in a feedback protocol scenario determined by a communication environment. The feedback information is constructed with information required by the communication environment.
摘要:
A method of transmitting/receiving feedback information representing channel quality in a MIMO-OFDM system, in which a receiver measures channel qualities of signals transmitted on a plurality of subbands through a plurality of transmitting antennas by a transmitter, selects a predetermined number of subbands having a highest transmission performance based on the measured channel qualities and preceding information, determines at least one subband group with a maximum rate from among the selected subbands and the preceding information associated with the at least one subband group, and transmits feedback information to the transmitter, the feedback information including channel quality information about the at least one subband group and the associated preceding information.
摘要:
A method and apparatus for transmitting/receiving feedback information in a multi-user multi-antenna system and a system supporting the same are provided, in which all possible combinations are created using column vectors included in a precoding codebook, column vectors are correlated in each of the combinations, column vectors comprising correlations exceeding a reference threshold are designated as similar vectors, at least two similar vector sets are formed with the similar vectors, and feedback information is generated based on the at least two similar vector sets and transmitted.
