Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0035] The process of configuring HARQ related information proposed by the embodiment of the present invention is as follows: figure 2 As shown, the steps involved are as follows:

[0036] Step 201: UE puts UE capability level information in an uplink RRC message and transmits it to RNC. The uplink RRC message may be: RRC connection request (RRC connection Request) message, cell update (CELL UPDATE) message, UTRAN registration area update (UTRANRegistration Area update, URA update) message, RRC connection setup complete (RRCconnection setup complete) message, the UE capability level information includes HSDPA capability level information: HS-DSCH physical layer capability level (HS-DSCH physical layer category) information and HSUPA capability level information: E-DCH p...

Abstract

The invention discloses a method for collocating hybrid automatic repeat request (HARQ) related information. The HARQ related information comprises total HARQ process number related with an HS-DSCH operation of user equipment (UE) and cache size corresponding to each process. A base station judges whether to feed back the HARQ related information to an RNC according to a data frame or a control frame of a user interface received through an Iub interface, if so, sets the HARQ process number N and the cache size corresponding to each process according to the pre-stored capability level information of the UE, generates the corresponding HARQ related information, and sends the HARQ related information of the UE to the RNC; the RNC transmits the received HARQ related information of the UE to the UE through special RRC message; and the UE updates the personal HARQ related information after receiving the HARQ related information through the special RRC message. The invention also discloses asystem for collocating the HARQ related information.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and system for configuring hybrid automatic repeat transmission related information. Background technique [0002] Hybrid automatic repeat request (HARQ) is an important technical feature in a high speed downlink packet access (High Speed ​​Downlink Package Access, HSDPA) system. An important feature in the HARQ process is the process identification (HARQ ID), and another important feature is the cache size (memory size) corresponding to each process. [0003] During the transmission of HSDPA downlink data, the base station (Node B) selects a process for downlink transmission of High-Speed ​​Downlink Shared Channel (HS-DSCH) data, first performs channel coding, and then encodes the The data is placed on the High-Speed ​​Physical Downlink Shared Channel (HS-PDSCH) channel and delivered to the user equipment (UE). The HS-DSCH data bears high-level se...
