Definitions

  • the present invention relates generally to a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system and, more particularly, to an improvement of a Serving and Neighbour cell Pathloss (SNPL) reporting mechanism of a User Equipment (UE) in a High Speed Uplink Packet Access (HSUPA) service/an uplink service of High Speed Packet Access enhancement (HSPA+) in the TD-SCDMA system.
  • TD-SCDMA Time Division-Synchronous Code Division Multiple Access
  • SNPL Serving and Neighbour cell Pathloss
  • UE User Equipment
  • HSUPA High Speed Uplink Packet Access
  • HSPA+ High Speed Packet Access enhancement
  • a high-throughput HSUPA service/a high-throughput uplink service of HSPA+ in a cellular communication system will cause a UE to generate high Rise over Thermals (RoTs) in a serving cell and neighbour cells of the UE. This problem gets worse for the neighbour cells when the UE is located on the edge of the serving cell.
  • RoTs Rise over Thermals
  • a Wideband Code Division Multiple Access (WCDMA) system introduces a physical channel called E-DCH Relative Grant Channel (E-RGCH) to solve the above-mentioned problem.
  • E-RGCH E-DCH Relative Grant Channel
  • the neighbour cells can use the E-RGCH to lower down the UE' s transmission power to reduce the RoTs in the neighbour cells.
  • a UE reports SNPLs for a serving cell and neighbour cells of the UE to the serving cell periodically.
  • Information about the SNPLs is used by the serving cell to control RoTs in the neighbour cells. For example, if a UE is close to a neighbour cell, a serving Base Station (BS) will give a less-power grant to the UE based on the reported SNPLs. As a result, the UE will not cause a high RoT in the neighbour cell.
  • BS Base Station
  • RoT control of neighbour cells greatly depends on frequency and accuracy of the SNPL reporting mechanism.
  • the SNPL reporting mechanism as stated above works well in a situation where a UE stays in one cell at all times. However, when the UE makes a handover to another cell, the SNPL reporting mechanism will suffer a serious problem. This problem is described in detail below.
  • a process relating to a handover of a UE can be divided into the following four stages.
  • the UE sends a measurement report to a Radio Network Controller (RNC) coupled to the UE via a serving BS serving a serving cell of the UE . If it is judged by the RNC based on the measurement report that a handover of the UE from the serving cell to a target cell is required, the RNC sends a Radio Link Reconfiguration Prepare message to a target BS serving the target cell and sends a Radio Bearer Reconfiguration message to the UE. Upon receipt the Radio Bearer Reconfiguration message, the UE prepares for the handover.
  • RNC Radio Network Controller
  • the UE can make an uplink transmission for the HSUPA service/the uplink service of HSPA+. Also, the UE can measure SNPLs for the serving cell and neighbour cells and report the measured SNPLs to the serving BS.
  • the UE executes the handover once it is ready for the handover. After the execution of the handover is finished, the UE sends a Radio Bearer Reconfiguration Complete message to the RNC. In this stage, the UE can neither make an uplink transmission for the HSUPA service/the uplink service of HSPA+ nor measure and report SNPLs.
  • the RNC sends to the UE a Radio Resource Control Layer 3 (RRC L3) measurement control message including a neighbour cell list of the target cell.
  • RRC L3 Radio Resource Control Layer 3
  • the UE Upon receipt of this neighbour cell list, the UE starts to measure SNPLs for all of cells in this neighbour cell list.
  • the UE can make an uplink transmission for the HSUPA service/the uplink service of HSPA+. But the UE can not measure and report SNPLs.
  • the UE reports the measured SNPLs to the target BS . In other words, now the UE can normally operate in the target cell.
  • the UE can make an uplink transmission for the HSUPA service/the uplink service of HSPA+ as well as measure and report SNPLs.
  • a traffic volume of the UE in stages 1 to 4 is schematically shown.
  • the traffic volume in stage 1 is low because the UE is located on the edge of the serving cell in this stage.
  • the traffic volume in stage 2 equals zero because of the execution of the handover.
  • the traffic volume in stage 3 is very low due to no SNPLs reporting.
  • the traffic volume in stage 4 is high because the target BS can receive SNPLs in this stage .
  • stage 3 the UE has to wait for the neighbour cell list of the target cell, to which the UE has switched, from the RNC because the UE needs to know the neighbour list before measuring the SNPLs. In other words, the UE can not start the SNPL measurement until it receives the neighbour list. Further, to keep network stability, the target BS will not give the UE a too much power grant before new valid SNPLs are measured.
  • stage 3 may last as many as 250 ms, which has a great negative impact on the throughput of the UE for the HSUPA service/the uplink service of HSPA+, as indicated in Fig. 1.
