摘要:
A method for HARQ reordering in Enhanced Uplink Dedicated Channel OF WCDMA system includes following steps: locating the soft combination buffer in the Node B and the reordering buffer in the SRNC; locating the HARQ entity in the Node B; locating the reordering queue distribution entity, the reordering entity and the disassembly entity in the SRNC. This invention adopts the separation technology of the soft combination buffer and the reodering buffer, the separation model can not only ensure the diversity gain, but also reduce the receiving delay and save the buffer space. Three mechanisms (timer mechanism, window mechanism and SBI mechanism) are proposed to prevent the blocking of the reordering buffer, which degrades the blocking to the least level, improves receiving efficiency and the system performance. Aiming at the SBI mechanism, the invention proposes the new DCH data frame structure on the lub interface and the lur interface.

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.
