The invention provides a metal carrier band for packaging a noncontact module with large size which is characterized in that the metal carrier band comprises a chip bearing region which can bear a chip of 3.9*4.5mm. The chip which is 1.5 times of the area of a common chip can be bear and packaged, and a module product with the same mechanical size is obtained. By the improvement of the metal carrier band and under the premise of the increased size of the packaged chip, the combining force of a mould body with the metal carrier band is improved to the maximum extent after the mould packaging, therefore, the mechanical force resistance of internal devices is improved greatly. The carrier band is packaged in a reeling way. Under the premise of not adding the investment, the present conventional packaging process and the existing equipment can be used for producing products with better quality, therefore, the application of high-end chips, such as noncontact intelligent electronic passport, EMV band card, and the like in the intelligent card field is expanded.

The present invention relates to the communication field, and discloses a DCI transmission method and device under cross-band carrier aggregation. The method is as follows: for LTE-A UEs that aggregate carriers with different TDD uplink / downlink configurations, according to pre-agreed rules or high-level The signaling configuration information determines whether the DCI format used for scheduling the PDCCH of the PUSCH includes the DAI and the UL index, and is independently determined for the CSS and the USS. In this way, the size of the DCI transmitted in the CSS can be guaranteed not to change, thereby ensuring the normal transmission of cell public information. At the same time, the specific bit fields in the DCI can be reasonably determined in the USS according to actual needs, thereby supporting UL multi-frame scheduling and / or Or resource overhead control of ACK / NACK on PUSCH.
