Definitions
- the present invention relates to a technique for determining a slot format of a Partial Dedicated Physical Control Channel (F-DPCH), and more particularly to a base station (Node B) in a mobile radio communication system that is in a cell forward access channel (CELL_FACH).
- CELL_FACH CELL Forward Access Channel
- CELL-FACH CELL-PCH (CELL-Paging Channel)
- URA-PCH UTRAN Registration Area_ Paging Channel
- HSPA High Speed Packet Access
- the basic principle of the uplink enhanced CELL_FACH technology is as follows: The random access transmission principle still uses the random access procedure of the Physical Random Access Channel (PRACH), but the channel type is changed, that is, in the Idle mode. And the CELL_FACH state can use E-DCH, Common Control Channel (CCCH), Dedicated Control Channel (DCC), Dedicated Traffic Channel (DTCH), and other logical channels can be mapped to E- Send on DCH.
- the E-DCH is mapped to the E-DCH Dedicated Physical Data Channel (E-DCHCH), and the E-DPDCH channel is required to pass the E-DCH dedicated physical control channel (E-DPCCH, E- The DCH Dedicated Physical Control Channel can work normally.
- the E-DPCCH is based on the Dedicated Physical Control Channel (DPCCH). Therefore, in the CELL_FACH state, the DPCCH needs to exist in the uplink, and the uplink DPCCH is required. The normal operation of the link is synchronized, so the downlink also needs to have a part of the dedicated physical control channel (F-DPCH, Fractional Dedicated Physical Control Channel).
- DPCCH Dedicated Physical Control Channel
- the Uu interface of the 3GPP protocol defines the Idle mode and the CELL_FACH state.
- the slot format used by the F-DPCH physical channel used by the UE is the slot format 0, and does not require a radio network controller (RNC) to pass the signal.
- RNC radio network controller
- there are only F-DPCH slot format configuration cells used in the Idle state and CELL_FACH state at the Iub port and there are 10 slot formats configurable in the F-DPCH, and there is no Ib interface protocol. Bright It is true that Node B can only use slot format 0.
- FIG. 1 is a schematic diagram of a frame format of an F-DPCH specified by the 3GPP protocol. As shown in FIG. 1 , in the frame format of the F-DPCH specified by the 3GPP protocol, neither Nofflbit nor Noff2bit transmit bits.
- the slot format that can be used by the F-DPCH specified by the 3GPP protocol is shown in Table 1:
- the difference between the slot format 0 and the other slot formats is that the position of the Transmit Power Control (TPC) bit in one slot is different. Therefore, the following problems exist: If the RNC configures a non-zero slot format for the F-DPCH, the Node B transmits the F-DPCH according to the non-zero slot format configured by the RNC, and the UE is fixed. The slot format 0 is used to receive the F-DPCH. As a result, the UE cannot receive the TPC bit information on the F-DPCH at the correct location, and the UE cannot perform the inner loop power control normally, thus causing the link to fail. Summary of the invention
- the main object of the present invention is to provide a method and a device for determining a slot format of a part of a dedicated physical control channel, so that the UE can correctly receive the TPC bit carried on the F-DPCH, so that the UE can use the TPC bit.
- the loop power control ensures that the base station can correctly receive the data information sent on the E-DPDCH.
- a method for determining a slot format of a portion of a dedicated physical control channel includes:
- the slot format of the dedicated physical control channel F-DPCH of the zero part is used as the transmission F.
- the base station before the base station detects that the UE in the CELL_FACH state or the Idle mode uses the E-DCH, the base station further includes:
- the signaling is a physical shared channel reconfiguration request message.
- the common E-DCH configuration information is carried in public E-DCH system information in the physical shared channel reconfiguration request message.
- An apparatus for determining a slot format of a part of a dedicated physical control channel comprising: a detecting unit and a determining unit, wherein
- a detecting unit configured to detect whether the UE in the CELL_FACH state or the Idle mode uses the E-DCH, and triggers the determining unit;
- the device further includes:
- a receiving unit configured to receive public E-DCH configuration information that is sent by the RNC through signaling, where the public E-DCH configuration information includes configuration information in an F-DPCH slot format, or the public E-DCH configuration information Does not contain configuration information for the F-DPCH slot format.
- the signaling is a physical shared channel reconfiguration request message.
- the public E-DCH configuration information is carried in a physical shared channel reconfiguration request cancellation In the public E-DCH system information in the interest.
- the Node B when the Node B determines that the current UE is in the Idle mode or/and the CELL_FACH state, the Node B will not press the F-DPCH notified by the RNC, whether or not the configuration information of the F-DPCH slot format notified by the RNC is received.
- the slot format is used as the format for transmitting information on the F-DPCH, but the slot format of the F-DPCH is used as the format for transmitting information on the F-DPCH, which ensures the slot format and UE of the F-DPCH transmitted by the Node B.
- the slot format of the received F-DPCH is the same, so that the UE can correctly receive the TPC bit carried on the F-DPCH, so that the UE can use the TPC bit to perform inner loop power control, and ensure that the Node B can correctly receive the E-DPDCH.
