Problems solved by technology

In the system information broadcast in a multi-carrier frequency cell, this shared physical channel configuration method that cannot distinguish frequencies obviously cannot realize the function of providing a shared channel on each carrier frequency
Because in the shared physical channel allocation process, this shared physical channel allocation method that cannot distinguish between frequencies will cause confusion and cannot clearly indicate the frequency properties of the shared physical channel

[0041] The method for configuring and using the shared channel in the multi-carrier cell system includes: establishing or reconfiguring the shared physical channel in the multi-carrier cell, allocating the shared physical channel to the UE on the network side, and allocating the shared physical channel to the UE on the UE side, etc. Three major processes. It should be pointed out that there is no time sequence requirement for allocating the shared physical channel to the UE on the network side or the UE side.

[0042] As shown in Figure 1, the method of this embodiment includes the following steps:

[0043] Step 110, during the shared physical channel reconfiguration process, the radio network controller and the node B (Node B), by including the carrier frequency indication information element (UARFCN) in the shared physical channel reconfiguration message, several carriers in the Node B Establish and configure shared physical channels on each frequency (including main carrie...

[0064] The difference between this embodiment and the first embodiment is that: in step 120, the broadcasted system information does not include the information of the shared physical channel; correspondingly, in step 170, the radio network controller allocates the shared physical channel for When the coded combined transport channel related to the shared transport channel allocates uplink and / or downlink shared physical channels on a carrier frequency, the message should contain "new configuration information element" (New configuration IE), which contains the shared physical Information about channel configuration. The difference from existing standards is that the frequency information element (Frequency info IE) needs to be added to the uplink shared physical channel information information element (PUSCH info IE) and the downlink shared physical channel information information element (PDSCH info IE), so as to Indicates the frequency attribute of the allocated shared phys...

Abstract

The invention discloses a configuration and application method for share channel in subzone system of multiple carrier frequency, which comprises: the RNC and node B respective create or reconfigure share physical channel on some carrier frequency of node B as well as the time slot format for transmission; RNC contains the configuration information and frequency property in broadcast system information; on network side, RNC and node B allocate one share physical channel on one carrier frequency for UE by Iub interface protocol; on UE side, TNC allocates one share physical channel on one carrier frequency for UE by Uu interface protocol; or, there is no information on share physical channel in broadcast system information, but on UE side, it allocates share physical channel and indicates the configuration information contained frequency property. This invention reduces capacity demand to UE and increases utility to wireless resource.

Description

technical field [0001] The invention relates to a TD SCDMA standard wireless communication system, in particular to a method for configuring and using a shared channel in a multi-carrier frequency cell system. Background technique [0002] Like other mobile communication systems, in order to meet the growing demand of the mobile communication market, multi-carrier frequency coverage in the same sector / cell will be an important means for TD-SCDMA system to increase system capacity [0003] Considering the cell search process in the system, the terminal measurement process, the handover decision process at the network side and the system efficiency, there is currently a multi-carrier frequency cell solution. That is, for the same sector cell area covered by multiple carrier frequencies, a cell (equivalent to a sector) adopts multiple carrier frequencies, in which there is only one main carrier frequency, and the others are called auxiliary carrier frequencies. In the same cel...
