Embodiment 1

[0065] The embodiment of the present invention realizes a HARQ configuration method of an auxiliary cell, such as image 3 As shown, the method mainly includes the following steps:

[0066] Step 101: RNC determines that UE adopts MF-HSDPA technology in Inter-NodeB mode;

[0067] Step 102: The RNC sends a Uu message to the UE, the Uu message carries the HARQ information of the MF-HSDPA secondary cell, and the HARQ information is used for the UE to configure the HARQ of the secondary cell.

[0068] In the above step 101, the RNC determines that the UE and the NodeB support MF-HSDPA according to the capabilities of the UE in the macro-diversity state and the capabilities of the NodeB, and determines the serving cell and the auxiliary serving cell according to the Inter-NodeB mode;

[0069] The RNC determines that the UE and the NodeB support MF-HSDPA according to the capability of the UE in the macro-diversity state and the capability of the NodeB, including: the RNC determines ...

Embodiment 2

[0075] The embodiment of the present invention realizes a HARQ configuration method of an auxiliary cell, such as Figure 4 As shown, the method mainly includes the following steps:

[0076] Step 201: The UE receives a Uu message carrying HARQ information of the MF-HSDPA auxiliary cell;

[0077] In this step, the Uu interface message may be a radio bearer establishment message or an active set update message. By parsing the radio bearer establishment message or the active set update message, the added field or preset The remaining field is used to analyze the HARQ information of the auxiliary cell of MF-HSDPA;

[0078] The HARQ information includes: number of processes, memory allocation mode; wherein, the memory allocation mode may be an implicit mode or an explicit mode.

[0079] Step 202: The UE saves the HARQ information, and performs HARQ configuration of the secondary cell according to the HARQ information.

[0080] Specifically, the UE saves the HARQ information, and...

Embodiment 3

[0082] The embodiment of the present invention realizes a HARQ configuration method of an auxiliary cell, such as Figure 5 As shown, the method mainly includes the following steps:

[0083] Step 301: RNC determines that UE adopts MF-HSDPA technology in Inter-NodeB mode;

[0084] Specifically, the RNC determines that the UE and the NodeB support MF-HSDPA according to the capabilities of the UE in the macro-diversity state and the capabilities of the NodeB, and determines the serving cell and the auxiliary serving cell according to the Inter-NodeB mode;

[0085] The RNC determines that the UE and the NodeB support MF-HSDPA according to the capability of the UE in the macro-diversity state and the capability of the NodeB, including: the RNC determines that the UE supports MF-HSDPA according to the capability reported by the UE in the macro-diversity state MF-HSDPA, determining that the NodeB supports MF-HSDPA according to the capability reported by the NodeB of the cell in the ...

Abstract

The invention discloses a hybrid automatic repeat request (HARQ) configuration method for an assisting cell. The HARQ configuration method comprises: an RNC (radio network controller) determines that UE (User Equipment) adopts an MF-HSDPA (Multi-Flow High Speed Downlink Packet Access) technology in an Inter-Node B mode, and sends a Uu port message to the UE, wherein the Uu port message carries HARQ information of the assisting cell of MF-HSDPA and the HARQ information is used for the UE to carry out HARQ configuration of the assisting cell; and the UE receives the Uu port message carrying the HARQ information of the assisting cell of MF-HSDPA, the HARQ information is stored and according to the HARQ information, HARQ configuration of the assisting cell is carried out. Meanwhile, the invention also discloses an HARQ configuration apparatus for the assisting cell.

Description

technical field [0001] The present invention relates to a multi-flow-high-speed downlink shared packet access technology, in particular to a hybrid automatic repeat request (HARQ) configuration method and device for an auxiliary cell. Background technique [0002] High-Speed ​​Downlink Shared Packet Access (HSDPA) and its evolution functions, such as dual-carrier (DC), dual-band-dual-carrier (DB-DC), and multiple-input multiple-output (MIMO), greatly improve the peak rate of the network and throughput, enhancing and improving the user's network experience. However, DC and other technologies have strict requirements on the operator's network frequency resources, which limits the application of DC; and, because HSDPA has no soft handover function, the performance of HSDPA users is poor when they are at the edge of the cell. , if the HSDPA resources of multiple cells can be utilized at the same time, it can not only improve user experience to a great extent, but also further i...
