Abstract:
A method for adaptively deciding number of feedback resource blocks in a downlink which comprises that a base station (500) determines a mode corresponding to the number of the feedback resource blocks which a user equipment feeds back by monitoring performance of a wireless cell and number of the user equipments (100) and transmits the mode to the user equipments (100) through signaling; the user equipments (100) listens to the mode and adaptively decides the number of feedback resource blocks by conditions of itself and feeds back downlink channel quality indicator information to the base station (500) according to Best channel quality indicator number or Threshold based feedback algorithm; and the base station (500) performs resource scheduling according to the feedback information. The present invention provides a method for adaptively deciding the number of feedback resource blocks based on base station signaling and user equipment decision, with respect to Best channel quality indicator number or Threshold based feedback algorithm in downlinks, thus insuring the performance of the wireless cell.

Abstract:
A method of notifying resource allocation for Demodulation Reference Signal (DMRS) is provided. A base station notifies to a user equipment a power offset value between an average EPRE value for data symbols and an average EPRE value for the DMRS at each layer in a semi-static or static manner. Also, the base station dynamically notifies to the user equipment a current channel rank or a current DMRS distribution pattern for the user equipment. The user equipment determines an allocated DMRS antenna port based on a correspondence between the received channel rank and an allocation of DMRS antenna port, thereby obtaining resource allocation information for the DMRS. The signaling overhead for power allocation in the system can be reduced, the efficiency of power amplifier can be improved and the flexibility of system scheduling can be increased. A method of notifying antenna port resource allocation for DMRS is also provided.

A developer cartridge is provided, which includes a toner cartridge, a developer stirring device located in the toner cartridge, a supply roller for supplying a developer to a developer roller, a developer roller for developing an electrostatic latent image on a photoconductor, and a power receptor for driving only one of gear sets of the above means to receive a power. The power receptor is rotatably fixed at two or more predetermined positions. An initial position of the power receptor is a power receiving position. A power receptor moving device includes a press block, a baffle block, a spring, and a torsion spring. The power receptor moving device is controlled by the press block. When the press block of the power receptor moving device is pressed downwards, the power receptor is rotated to another power receiving position due to the action of the torsion spring. The present invention is applicable to various types of machines.

Abstract:
The present invention provides a method and a coder for jointly coding Pre-coding Matrix Index #1 (W1) and Rank Index (RI) for channel state information feedback of a double codebook precoding frame. In the present invention, it is determined whether Rank Index RI is more than 2; if the RI is no more than 2, a first half branch of a coding binary tree is used to represent joint coding of the RI and W1 when RI=1 and RI=2; if the RI is more than 2, a second half branch of the coding binary tree is used to represent remaining separate codings and/or joint codings when the RI is more than 2; and processing results of the above coding steps are output. The present invention may be applied to an equal-length coding or an unequal-length coding. The present invention has advantages such as easy implementation, lower signaling overhead etc., and may be suitable for an LTE-A/4G cellular communication system and a future 5G cellular communication system.
