Abstract
Abstract A method for transmitting TFCI for DSCH and TFCI for DCH in a CDMA communication system is disclosed. A SRNC (Serving Radio Network Controller) transmits DSCH data to a DRNC (Drift RNC). Upon receipt of the DSCH data from the SRNC, the DRNC determines transmission time of the DSCH data, and then, transmits the corresponding TFCI to the SRNC using frame protocol and the DSCH data to a Node B. The SRNC determines DCH data and its TFI, and transmits them to the Node B. The Node B then transmits the data and TFCI to a UE over DPCH.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
162 words
A method for transmitting a signal in a logical split mode in a CDMA (Code Division Multiple Access) mobile communication system including a UE (User Equipment), a Node B for transmitting data on a dedicated channel (DCH) and packet data on a downlink shared channel (DSCH) to the UE, a first RNC (Radio Network Controller) for transmitting the data to the Node B, and a second RNC for transmitting the packet data received from the first RNC to the Node B, the method comprising the steps of: generating and transmitting scheduling information including transport format combination indicator (TFCI) information for the packet data from the second RNC to the first RNC using frame protocol upon receipt of the packet data; transmitting the TFCI information of the packet data from the first RNC to the Node B upon receipt of the scheduling information; and transmitting the packet data from the second RNC to the Node B after the transmission of the TFCI information.
Claim 2
Independent Claim
162 words
A method for transmitting a signal in a logical split mode in a CDMA (Code Division Multiple Access) mobile communication system including a UE (User Equipment), a Node B for transmitting data on a dedicated channel (DCH) and packet data on a downlink shared channel (DSCH) to the UE, a first RNC (Radio Network Controller) for transmitting the data to the Node B, and a second RNC for transmitting the packet data received from the first RNC to the Node B, the method comprising the steps of: generating and transmitting scheduling information including transport format combination indicator (TFCI) information for the packet data from the second RNC to the first RNC using frame protocol upon receipt of the packet data; transmitting the TFCI information of the packet data from the first RNC to the Node B upon receipt of the scheduling information; and transmitting the packet data from the second RNC to the Node B after the transmission of the TFCI information.
Claim 3
Independent Claim
113 words
A method for transmitting a DCH data in an asynchronous CDMA mobile communication system including a UE User Equipment), a serving RNC and a drift RNC corresponding to the UE, comprising the steps of: transmitting DSCH data from an SRNC (Serving RNC) to a DRNC (Drift RNC); generating a first TFCI information about a DSCH by the DRNC; transmitting scheduling information including the generated first TFCI information from the DRNC to the SRNC using frame protocol; transmitting the first TFCI information from the SRNC to the Node B by the scheduling information; and transmitting the DSCH data from the SRNC to the Node B after transmission of the TFCI by the scheduling information.
Claim 4
Independent Claim
113 words
A method for transmitting a DCH data in an asynchronous CDMA mobile communication system including a UE User Equipment), a serving RNC and a drift RNC corresponding to the UE, comprising the steps of: transmitting DSCH data from an SRNC (Serving RNC) to a DRNC (Drift RNC); generating a first TFCI information about a DSCH by the DRNC; transmitting scheduling information including the generated first TFCI information from the DRNC to the SRNC using frame protocol; transmitting the first TFCI information from the SRNC to the Node B by the scheduling information; and transmitting the DSCH data from the SRNC to the Node B after transmission of the TFCI by the scheduling information.
Claim 5
Dependent Claim
39 words
The method of claim 2 , further comprising the step of: generating a second TFCI information about a DCH by the SRNC; and transmitting a DPDCH data and the second TFCI information from the SRNC to the Node B.
Claim 6
Independent Claim
146 words
An apparatus for transmitting a signal in a logical split mode in a CDMA mobile communication system including a UE, the apparatus comprising: a Node B for transmitting data on a dedicated channel (DCH) and packet data on a downlink shared channel (DSCH) to the UE, a first RNC for transmitting the data to the Node B, and a second RNC for transmitting the packet data received from the first RNC to the Node B; the second RNC, upon receipt of the packet data, transmitting scheduling information including TFCI information for the packet data to the first RNC using frame protocol, and transmitting the packet data to the Node B after transmission of the TFCI information to the Node B; and the first RNC, upon receipt of the scheduling information, transmitting the TFCI information of the packet data to the Node B by the scheduling information.
Claim 7
Independent Claim
146 words
An apparatus for transmitting a signal in a logical split mode in a CDMA mobile communication system including a UE, the apparatus comprising: a Node B for transmitting data on a dedicated channel (DCH) and packet data on a downlink shared channel (DSCH) to the UE, a first RNC for transmitting the data to the Node B, and a second RNC for transmitting the packet data received from the first RNC to the Node B; the second RNC, upon receipt of the packet data, transmitting scheduling information including TFCI information for the packet data to the first RNC using frame protocol, and transmitting the packet data to the Node B after transmission of the TFCI information to the Node B; and the first RNC, upon receipt of the scheduling information, transmitting the TFCI information of the packet data to the Node B by the scheduling information.
