摘要:
Provided is a method and an apparatus for transmitting/receiving a Broadcast Channel (BCH), by which a User Equipment (UE) can successfully receive system information of neighboring cells in a system supporting the scalability of a UE reception bandwidth and a system bandwidth. The method includes identifying a system bandwidth of a cell by comparing the system bandwidth with reception bandwidths of UEs within the cell, mapping two BCH information blocks including system information to a central band having a bandwidth equal to a transmission bandwidth of the BCH, additionally mapping at least one of the information blocks into each of one-half bands of the system bands, when the system bandwidth is two times an amount of the reception bandwidth, and transmitting a frequency domain signal, to which the information blocks are mapped, to the UEs located within the cell.

A method and apparatus for transmitting control information of a small block size with high reliability in a mobile communication system supporting uplink packet data service are provided. A 6-bit Absolute Grant indicating an allowed maximum data rate for uplink packet data transmission is generated and a 16-bit User Equipment Identifier Cyclic Redundancy Check is generated by combining a Cyclic Redundancy Check with a User Equipment Identifier. The User Equipment Identifier specific Cyclic Redundancy Check and 8 tail bits are added to the 6-bit Absolute Grant and the added bits are encoded at a coding rate of 1/3. The resulting 90 coded bits are rate-matched according to a predetermined rate matching pattern and transmitted to a User Equipment. The rate matching pattern is {1,2,5,6,7,11,12,14,15,17,23,24,31,37,44,47,61, 63, 64, 71, 72, 75, 77, 80, 83, 84, 85, 87, 88, 90}.

摘要:
In an asynchronous CDMA mobile communication system supporting HSDPA (High Speed Downlink Packet Access), in order to assign power to a high speed physical downlink shared channel (HS-PDSCH), a power offset is determined and then provided to a Node B and a user equipment (UE). For this, an HS-PDSCH power offset is determined by a controlling radio network controller (CRNC) and a Node B, and then transmitted to the UE or the Node B.

A method in a UE of transmitting buffer state information and CSI for scheduling an uplink packet data service in a mobile communication system supporting the uplink packet data service is provided. The buffer state information indicates a state of a data buffer for storing packet data to be transmitted from the UE and the CSI indicates an uplink transmit power of the UE. The UE acquires different transmission intervals of the buffer state information and the CSI, initially transmits the buffer state information and the CSI, if the amount of packet data stored in the buffer is equal to or greater than a predetermined threshold, and periodically transmits the buffer state information and the CSI at the transmission intervals.
摘要:
A method and apparatus for providing a service based on multiple data rates using scalability of a multimedia CODEC in an asynchronous code division multiple access (CDMA) communication system, which provides a multimedia broadcast and multicast service (MBMS). An entire cell area is divided into a first area and a second area. Specific data is separated into first data and second data. The first data is transmitted to the first area, and the second data is transmitted to the second area. A first electric power controller controls electric power for the first data. A second electric power controller controls electric power for the second data. A user equipment (UE) located in the second area receives the first data and the second data. The UE located in the second area combines the first data and the second data, thereby generating one data item.
摘要:
A method for transmitting pilot bits instead of partial bits of CQI (Channel Quality Indicator) information indicating channel quality of an HS-PDSCH (High Speed-Physical Downlink Shared CHannel) in a CDMA (Code Division Multiple Access) communication system such that a Node B can control power of a high-speed uplink control channel. The system transmits high-speed packet data from the Node-B to UE (User Equipment) through the HS-PDSCH, and the UE is located in a handover area between the Node-B and another Node-B adjacent thereto. In the method, the CQI information is received and code symbols of given bits are generated. Predetermined bits are then removed from given bits of the code symbols. The removed bits are then replaced with high-speed pilot bits for power control.

摘要:
Disclosed is a method for controlling uplink transmission power in a handover region by a UE in communication with a Node B using an FCS scheme. The UE stores TPC commands received for a specific duration from a plurality of cells in an active set, if the UE enters in the handover region during communication with a current best cell. If a next best cell is selected from the plurality of the cells, the UE determines a transmission power offset by comparing TPC commands from the current best cell with TPC commands from the next best cell for the specific duration at a time point where the best cell is changed from the current best cell to the next best cell. The UE transmits initial transmission power for the next best cell at a transmission power level determined considering the transmission power offset.

摘要:
The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). Next generation of wireless cellular operation is expected to be deployed in higher frequency above 6 GHz (eg. 10 GHz ∼ 100 GHz, also called mmWave and/or cmWave) due to availability of large amount of spectrum bandwidths. The physical layer of wireless cellular system in both DL and UL operating in mmWave/cmWave would be based on new air-interface different from that of LTE-A air-interface because the radio characteristics is different for mmWave/cmWave bands. The wireless system deployed in mmWave/cmWave system is expected to employ DL beam sweeping on broadcast control information to provide cell coverage to the UE which would result in excessive signaling overhead.
