Abstract:
PURPOSE: A system for feedback signaling, a method thereof, and an 8-TX code book in a 3GPP wireless network are provided to reduce feedback overhead of release 10 of the 3GPP wireless network. CONSTITUTION: Mobile terminals(111-116) transmit feedback values to a base station(102) of a wireless network for using a wireless network. The feedback values include a first pre-coder matrix indicator value and a second pre-coder matrix indicator value. The mobile terminals transmit the second pre-coder matrix indicator value from a sub-frame, which is the same as a channel quality indicator value, to the base station.

Abstract:
PURPOSE: A system and method for bundling a resource block in a wireless communication system are provided to activate a physical resource block bundling in a system FDD operation mode, and to deactivate the physical resource block bundling in a system TDD operation mode. CONSTITUTION: A base station(101,102,103) transmits a downlink frame to a first mobile terminal to be used in a wireless network which communicates with a plurality of mobile terminal(111-116). The downlink frame comprises the time-frequency resource elements which are allocated in a plurality of physical resource blocks. The base station transmits the plurality of physical resource blocks in the bundles which have a bundle size of a function of a system bandwidth configuration. The base station uses the same precoder in all physical resource blocks in the same bundle. [Reference numerals] (101, 102, 103) Base stations; (130) Internet
Abstract:
PURPOSE: A method and system for resource block bundling in an LTE-A system are provided to receive feedbacks from a subscriber terminal by including a receiving path circuit in a base station. CONSTITUTION: A pointer of a first feedback mode or a second feedback mode is transmitted to a subscriber terminal(1601). The base station sets a precoding unit in a frequency domain for multiple physical resource blocks in order to perform the same precoding through the bundled resource blocks(1605). The bundled resource blocks include multiple consecutive physical resource blocks in the frequency domain The base station sets the precoding unit about for one physical resource block(1607). A feedback is received from the subscriber terminal(1609).
