Problems solved by technology

[0011] However, the current protocol does not specify how the network side informs the UE which E-DCH MAC flow different logical channels are mapped to; for DCCH / DTCH, it can be notified in the resource block (RB, Resources Block) mapping information (RB mapping info) , but for CCCH mapping to E-DCH, UE will not be able to choose which E-DCH MAC flow to use, and UE will not be able to uniquely choose which Hybrid Automatic Repeat reQuest (HARQ, Hybrid Automatic Repeat reQuest) profile to use, which will cause UE and The HARQ profile information used by Node B (NodeB) is inconsistent, which eventually leads to decoding errors

Embodiment Construction

[0045] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0046] A method for mapping logical channels and MAC streams provided by the present invention, such as figure 1 As shown, it mainly includes the following steps:

[0047] In step 101, the RNC notifies the UE of the corresponding relationship between the CCCH and the E-DCH MAC flow through signaling.

[0048] The signaling may be a system broadcast message, such as system broadcast message 5 and / or system broadcast message 5bis. The so-called correspondence between CCCH and E-DCH MAC flow in the present invention means that the E-DCH MAC flow identifier corresponding to CCCH is given in the signaling.

[0049] In step 102, the UE receives the signaling, and obtains the corresponding relationship between the CCCH and the E-DCH MAC flow in the signaling.

[0050] Since the correspondence between the E-DCH MAC flow i...

Abstract

The invention discloses a mapping method of logical channels and media access control (MAC) flow. The method comprises the following steps: a radio network controller (RNC) informs user equipment (UE) of the corresponding relation between a common control channel (CCCH) and the MAC flow of an enhanced dedicated channel (E-DCH) through signaling; and the UE receives the signaling, and acquires the corresponding relation between the CCCH and the MAC flow of the E-DCH. The invention further discloses a mapping system of the logical channels and the MAC flow. By utilizing the method and the system disclosed by the invention, NodeB and the UE can accurately learn the corresponding relation between the CCCH and the MAC flow of the E-DCH so as to ensure that the NodeB can correctly decode and improve the success rate for receiving the signaling and data.

Description

technical field [0001] The invention relates to delay processing technology in mobile communication, in particular to a mapping method and system of logical channel and medium access control (MAC) flow. Background technique [0002] Two basic working modes of a mobile user terminal (UE, User Equipment) are an idle (IDLE) mode and a connected mode. The so-called IDLE mode refers to the state when the UE is in the standby state and there is no service; the so-called connected mode refers to the fact that the radio resource control (RRC, Radio Resource Control) has been completed between the UE and the radio network controller (RNC, Radio Network Controller). Control) state when the connection is established, and the UE has camped in a cell at this time. In the connection mode, the UE has four states in total, which are Cell_DCH, Cell_FACH, Cell_PCH, and URA_PCH states. The so-called Cell_DCH state refers to the state in which the UE uses a dedicated channel for communication...
