Embodiment Construction

[0029] The method of the present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0030] In order to implement Node B to configure TPC parameters for high-speed shared information signal closed-loop power control in a TD-SCDMA system, the present invention provides a method for Node B to configure TPC parameters for HS-SICH closed-loop power control, It mainly includes the following steps:

[0031] (1) Node B obtains the parameters "Ack-Nack power offset" and "HS-SICHSIR Target" configured by the upper layer, and obtains the actual power measurement value P of the high-speed shared information channel through measurement HS-SICH , and decode the ACK / NACK information carried on the high-speed shared information channel;

[0032] (2) Node B obtains the measured P HS-SICH , and the ACK / NACK information obtained by decoding, to obtain the transmission power value of the high-speed shared information channel configu...

Abstract

The invention disclose a power control parameter method for node B configuring the high sharing channel, in the time synchronization code multi-address TD-SCDMA system, firstly, the node B obtains the parameters of 'Ack-Nack power offset' and 'HS-SICH SIR Target', by measuring the real power value PHS-SICH and the ACK / NACK information carried by sharing information channel; according to the said information, the node B obtains the sending power value of sharing information channel, and compares with the parameters of HS-SICH SIR Target', and determine the parameter value of 'TPC' according to the result. Further, the TPC parameters can be sent to the user's device. The method in the invention reinforces the disadvantages in the present technology protocol, and realizes the node B configuring the TPC parameters for the high sharing information channel.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular to a method for Node B to configure power control parameters of a high-speed shared information channel. "TPC" parameter for power control. Background technique [0002] High-speed downlink packet access (HSDPA) technology is a technology that provides high-speed downlink data services for multiple users, and is suitable for services that require a large amount of downloading information such as multimedia and Internet. HSDPA introduces a new transmission channel HS-DSCH (High Speed ​​Downlink Shared Channel), in which users share downlink code resources and power resources for time division multiplexing. This structure is suitable for bursty packet data services. The downlink physical channel HS-SCCH (High Speed ​​Shared Control Channel) is used to bear the physical layer control signaling used for decoding on the HS-PDSCH (High Speed ​​Physical Downlink ...
