Abstract:
The present disclosure discloses a method and system for transmitting downlink control information, for solving the problem of how to indicate a transmission scheme when a cyclic redundancy check code in the downlink control channel is scrambled with the semi-persistently scheduled cell radio network temporary identifier. In order to support the bi-flow beam forming technology in the LTE-A R9, the present disclosure provides a downlink control information Format 1A, which may, when the cyclic redundancy check code in the downlink control channel is scrambled with the semi-persistently scheduled cell radio network temporary identifier, indicates a method for transmitting downlink control information, for example, single-layer transmission, transmit diversity, or a transmission scheme simultaneously involving single-layer transmission and transmit diversity, which guarantees flexibility of system schedule. The present disclosure adds no signaling overhead and has good adaptability with the LTE R8.
Abstract:
The present invention discloses a method and a system for non-periodic feedback in a carrier aggregation scenario. The method comprises: a base station sending a non-periodic trigger signaling to a piece of User Equipment (UE); the UE receiving the non-periodic trigger signaling, and determining a Downlink Component Carrier (DL CC) requiring feedback according to the non-periodic trigger signaling; the UE triggering a non-periodic feedback of the determined DL CC. With the present invention, the problem that it is impossible to determine which downlink component carrier is to be fed back according to the non-periodic trigger signaling in the carrier aggregation scenario is solved, uplink feedback of the DL CC that is unnecessary to be fed back is effectively reduced, the base station can adjust resource allocation according to information fed back by the UE, and the performance of downlink data transmission is ensured.
Abstract:
The disclosure discloses a method and system for transmitting a Physical Random Access Channel (PRACH). The method includes: in a Carrier Aggregation (CA) scenario, a base station transmits, in a Primary Serving Cell (Pcell) or a Secondary Serving Cell (Scell), a random access trigger message to a User Equipment (UE) (401); the UE transmits, in the Scell, a PRACH (402); and the base station transmits, in the Pcell or an Scell, a random access procedure message to the UE (403). With the disclosure, a PRACH can be transmitted in an Scell in the CA scenario.
Abstract:
The present invention discloses a method for detecting downlink control information, including: when scheduling across carriers is enabled, determining by user equipment (UE) user-specific search space monitoring a physical downlink control channel (PDCCH) according to component carrier indexes, wherein the component carrier indexes include component carrier indexes corresponding to various component carriers implementing scheduling across carrier and being scheduled across carriers. Also the present invention also provides an apparatus for detecting downlink control information, a user equipment and a network side device. The present invention solve the overlap problem of common search space and user-specific search space in Release 10 and solves the problem of determining a search space for the PDCCH in the situation of scheduling across carriers is enabled in Release 10.

Abstract:
A method for making a housing of an electronic device includes applying a layer of ceramic powder material to an outer surface of a metal substrate. The layer of ceramic powder material and a top layer of the metal substrate are melted by laser irradiation, forming a ceramic-metal composite coating integrally bonding with the metal substrate when cooled. The substrate with the ceramic-metal composite coating is heated to a peak temperature, maintained at the peak temperature for a desired period of time, and then cooled down to room temperature. The heat treated metal substrate with the ceramic-metal composite coating is then formed into a desired shape.
