Abstract:
1. A method for implementing power control of a high speed shared information channel (HS-SICH), used in High Speed Downlink Packet Access (HSDPA) technology in a TD-CDMA system to perform power control for the high speed shared information channel (HS-SICH) sent by a user equipment to a Node B, including the steps of: configuring parameters related to the power control for the user equipment by a network side through higher layer signaling, said parameters including parameters used to calculate initial transmit power; calculating the initial high speed shared information channel (HS-SICH) transmit power used for open-loop power control by the user equipment according to said parameters configured; adjusting close-loop power control of the high speed shared information channel (HS-SICH) by the user equipment according to a “transmit power control” parameter calculated by the Node B and carried on a high speed shared control channel (HS-SCCH); the method further including the steps of: configuring the parameters related to the power control for the user equipment by the network side through the higher layer signaling, said parameters including a “high speed shared control channel (HS-SCCH) block error ratio target” parameter; taking the “high speed shared control channel (HS-SCCH) block error ratio target” parameter configured by the higher layer as a target value by the user equipment; measuring the received block error ratio of the high speed shared control channel (HS-SCCH) by the user equipment to obtain an actual value of “high speed shared control channel (HS-SCCH) block error ratio”; and calculating “transmit power control” information by the user equipment according to said target value and said actual value, and carrying the “transmit power control” information on the high speed shared information channel (HS-SICH); wherein the step of said network side configuring the parameters related to the power control for the user equipment through the higher layer signaling includes uniformly configuring a set of parameters related to the power control for the whole high speed shared information channel (HS-SICH) set of the user equipment; and the parameters related to the power control configured by said network side for the user equipment through the higher layer signaling are configured through an information element “high speed shared control channel (HS-SCCH) Information” in a “Radio Resource Control” protocol.
