Embodiment Construction

[0042] Take the HSDPA technology in the TD-SCDMA system as an example below to describe the specific implementation of the present invention in detail, figure 2 Shown is the flow chart of the training code allocation method of the present invention, which specifically includes the following steps:

[0043]Step 201, when the RNC configures the HS-PDSCH (high-speed physical downlink shared channel) physical channel shared resource pool to the Node B, the allocation mode in the training code allocation information of the HS-PDSCH physical channel is configured as the default training code allocation mode;

[0044] The RNC initiates a Physical Shared Channel Reconfiguration (Physical Shared Channel Reconfiguration) process to configure the HS-PDSCH physical channel shared resource pool for dynamic scheduling, and sends a Physical Shared Channel Reconfiguration Request (PHYSICAL SHARED CHANNELRECONFIGURATION REQUEST) message to the Node B. In this message, configure the MidambleAl...

Abstract

The invention provides a training code allocation method for physical channels, which is applicable to dynamic scheduling and comprises the following steps: (a) a radio network controller (RNC) configures the shared resource pool of business physical channels for the Node B of a base station, wherein, the shared resource pool is used for the dynamic scheduling, and a training code allocation mode in the training code allocation information of the business physical channels is configured to be a default training code allocation mode; (b) the RNC configures a dynamic scheduling resource for user equipment (UE) in a network side and does not configure the training code allocation information of the business physical channels; (c) the RNC allocates the dynamic scheduling resource for the UE in a UE side and configures the training code allocation mode of the business physical channels to be the default training code allocation mode. The invention ensures that the training codes allocated at the Node B side are in accord with the training codes allocated at the UE side, meanwhile, a training code using method in the default training code allocation mode is optimized.

Description

technical field [0001] The invention relates to a synchronous wireless communication system, in particular to a method for distributing training codes of dynamically scheduled physical channels in the wireless communication system. Background technique [0002] In mobile communication applications, multipath distortion may occur, so it is necessary to send some training sequences or data with known content so that the receiver can perform channel estimation. The information needed to estimate the characteristics of the transmission channel is contained in the impulse response of the channel, as is well known in the art. The training sequence can be called training code, Midamble code or intermediate code. Training codes are required in both the uplink from the mobile terminal to the base station and the downlink from the base station to the mobile terminal in order to estimate the condition of each transmission path to and from each user. figure 1 Shown is the general burs...
