Embodiment 1
[0034] image 3 It is a preferred flowchart of a method for notifying independent midamble configuration information according to an embodiment of the present invention, which includes:
[0035] S302, the radio network controller RNC sets the configuration information of the independent midamble;
[0036] S304, the above-mentioned RNC sends the above-mentioned configuration information to the NodeB through the user plane;
[0037]S306, the above-mentioned RNC sends the above-mentioned configuration information to the terminal. Preferably, the terminal communicates with the NodeB; preferably, the RNC sends the configuration information to the terminal through an RRC message.
[0038] In this preferred embodiment, since the RNC sends the configuration information to the NodeB through the user plane, the NodeB can use the independent midamble configuration information to perform uplink channel estimation under CELL_FACH, so as to realize functions such as judging user space iso...
Embodiment 2
[0048] This embodiment mainly describes a specific method of carrying configuration information through an HS-DSCHFPtype2 frame. Figure 4 is a schematic structural diagram of an HS-DSCHFPtype2 frame according to an embodiment of the present invention, such as Figure 4 As shown, the specific configuration for carrying the configuration information through the HS-DSCHFPtype2 frame includes at least one of the following:
[0049] a) The number of users in a time slot, the values are K=2, 4, 6, 8, 10, 12, 14, 16, which are represented by 3 bits standalonemidambleconfig, and the corresponding method is: (standalonemidambleconfig+1) *2
[0050] In the TD-SCDMA system, generally K=8, that is, the value of standalonemidambleconfig is generally "011".
[0051] b) standalone midamble offset, which takes an integer value from 0 to 15, and is represented by 4 bits here.
[0052] c) The cycle of standalone midamble transmission, represented by 4 bits, and the unit is TTI (a TTI is 5...
Embodiment 3
[0058] Figure 5 It is another preferred flow chart of the notification method of independent midamble configuration information according to an embodiment of the present invention, which includes:
[0059] Step S502: The RNC configures the independent midamble configuration information related to the sounding signal to the terminal through an RRC message. The relevant configuration content is the same as that of the implementation examples 1 and 2. The RRC message can be a cell update confirmation message, a physical channel reconfiguration message, and a transport channel Reconfiguration message, RB reconfiguration message, RB establishment message, etc.
[0060] Step S504: The RNC sends the independent midamble configuration information related to the sounding signal to the NodeB through HS-DSCHFPtype2. Refer to Embodiments 1 and 2 for the independent midamble configuration information related to the sounding signal and the HS-DSCHFPtype2 structure.
[0061] Step S506: The...
