  • Publication number: 20120201121
    Abstract: An embodiment of the present invention discloses a high speed uplink packet access adaptive retransmission method and apparatus. The method includes: obtaining a resource limitation state; performing adjustment decision according to the resource limitation state and a current target number of retransmissions of a UE; and adjusting the target number of retransmissions of the UE between a preset large target number of retransmissions and a preset small target number of retransmissions, where the large target number of retransmissions is greater than the small target number of retransmissions. The utilization rate of resources may be effectively improved.

  • Publication number: 20120094704
    Abstract: A method and a communications system are provided. The system includes a Node B and a RNC. The Node B report the RNC whether the base station an E-DPCCH power boost capability. The RNC is also informed whether a UE supports and E-DPCCH power boost capability. If the Node B and the UE both support the E-DPCCH power boost capability, the RNC configures the resource for the Node B to perform channel estimation by using the E-DPCCH power boost feature for the UE. Through the solution of the system, the accuracy of channel estimation can be improved and thus a bit error rate in high-speed data transmission can be reduced.

  • Publication number: 20120033631
    Abstract: A method for controlling a working mode of a high speed downlink packet access (HSDPA) system includes steps as follows. When an activation state of a high speed shared control channel (HS-SCCH) less operation mode needs to be changed, a base station transmits a physical layer signaling for activating or deactivating the HS-SCCH less operation mode to a user equipment (UE), so as to instruct the UE to activate or deactivate the HS-SCCH less operation mode. The UE activates or deactivates the HS-SCCH less operation mode according to the physical layer signaling for activating or deactivating the HS-SCCH less operation mode from the base station.

  • Publication number: 20110207498
    Abstract: A resource configuration method includes acquiring capability information of a base station (BS), in which the capability information of the BS includes information indicating whether the BS has channel power boost capability. Capability information of a user equipment (UE) is acquired. The capability information of the UE includes information indicating whether the UE has the channel power boost capability. The BS is notified to configure resources for performing channel estimation by using the channel power boost capability for the UE if the UE and the BS both have the channel power boost capability.
