Abstract

The invention is concerned with a renewed method of wireless link parameter based system capability and channel quality evaluation. A step is carrying initialization dispose to select corresponding threshold value, parameter combination and register to initialize each module according to adjustment arithmetic. B step is evaluating system capability and channel quality of user in periodicity by evaluating device. C step starts clock arbitration device to decide the renewed standard of parameter. When the standard is same as the system capability, it jumps to D step, when it is channel quality, jumps to f step. D step judges whether the system capability exceeds the threshold by evaluating device, when it is over the threshold, the counter starts the renew order. E step counts the renew parameter value according to the system capability and jumps to H step. F step sends parameter renewing order to the counter, when the channel quality is over the threshold. G step counts renewing parameter value according to channel quality. H step sends parameter renewing information of wireless link to parameter renewing module.

Description

technical field

[0001] The present invention relates to a method for updating radio link parameters based on system performance and channel quality evaluation in a mobile communication system, in particular to an uplink high-speed dedicated physical control channel (HSDPA) in a high-speed downlink packet access system (HSDPA) - A method for updating radio link parameters of DPCCH). Background technique

[0002] HSDPA provides users with high-speed data services by adding high-speed downlink shared data channel (HS-DSCH), downlink high-speed control channel (HS-SCCH) and uplink high-speed dedicated physical control channel (HS-DPCCH). The downlink HS-DSCH data channel is used to transmit all user data in the cell; the downlink HS-SCCH control channel is used to transmit physical layer signaling for receiving data; the uplink HS-DPCCH control channel is used to transmit channel quality feedback information (CQI) and HARQ acknowledgment information (ACK / NACK).
