摘要:
Multiple Transport Blocks (TBs) or data streams are provided in Multi-Input-Multi-Output (MIMO) wireless communication systems herein. The base station (eNB) controls and schedules all downlink and uplink transmission to and from User Equipments, which need to receive an uplink grant from BS/eNB before they transmit. The uplink grant is carried as one of the control indication message in the downlink. The BS/eNB also transmits ACK/NACK information in the HARQ indication channel to the UE for each of the transport blocks. The UE detects the control indication to determine the actual uplink scheduling, as well as the HARQ indication. A method of transmitting a control indication message, which contains a detailed transmit format for one of the TBs to be transmitted, while allowing simultaneous communications on the other TBs is also enclosed.

Provided is a method for performing communication with a network by a User Equipment (UE) based on its speed information in the network in which at least one portion includes at least one micro cell overlapping at least one macro cell. The method includes measuring, by the UE, its moving speed; and performing at least one of feedback, measurement report, random access and UE capability report to the network by considering the measurement result.

An apparatus and method are provided for transmitting and receiving a pilot signal using multiple antennas in an OFDM mobile communication system. In the pilot transmitting apparatus, at least one Walsh coverer Walsh-covers a pilot signal to be sent through each of transmit antennas. At least one transmitter allocates the Walsh-covered pilot signals to a predetermined subcarrier in every OFDM symbol and transmits the allocated pilot signals through the transmit antennas.

A method and apparatus for transmitting Channel State Information Reference Symbol (CSI-RS) and data with partial muting of the CSI-RS are proposed. The method includes determining a CSI-RS pattern to be used among CSI-RS pattern candidates, determining a muting pattern for muting some resource elements constituting CSI-RS pattern candidates except for the determined CSI-RS pattern, mapping data symbols and CSI-RS to resource elements in a resource grid with rate patching in consideration of the CSI-RS pattern and muting pattern, and transmitting the data symbols and CSI-RS to a terminal.

Methods and apparatus are provided for transmitting processing reference signals in a mobile communication system. A base station determines a reference signal pattern comprising at least one resource element, generates a bitmap indicator indicating whether zero transmission power is assigned to the at least one resource element of the reference signal pattern, and transmits the reference signal pattern and the bitmap indicator to a terminal. The terminal receives the reference signal pattern and the bitmap indicator, and processes a reference signal extracted according to the reference signal pattern and the bitmap indicator.

A mobile station determines a data rate in a mobile communication system including a plurality of base stations communicating with the mobile station. The mobile station receives rate control information from the base stations, and receives precedence indicator information from one of the base stations. The precedence indicator information is used for giving precedence to particular rate control information in the rate control information received from the base stations. The mobile station determines a data rate according to the particular rate control information to which precedence is given by the precedence indicator information.
摘要:
A method and apparatus for transmitting a broadcast physical layer packet in a mobile communication system supporting multi-slot transmission and hybrid Automatic Repeat Request (H-ARQ) are provided. The method comprises initially transmitting the broadcast physical layer packet according to a fixed transmission format for at least one first slot interval and retransmitting the broadcast physical layer packet for at least one second slot interval using a variable transmission format different from the transmission format used in the first slot interval.
