Problems solved by technology

For a user's data (CCCH\DCCH\DTCH), the AOA of all transmission blocks in a TTI is the same, and single user data cannot fill up to 4 transmission blocks every time. Take the RLC confirmation frame of DCCH\DTCH as an example , only one transmission block of FACH is used, and the utilization rate of FACH channel is only 25%, which greatly limits the network capacity

Embodiment Construction

[0037] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] The present invention proposes a method for realizing multi-user shaping based on FP frame extension fields, such as image 3 shown, which includes:

[0039] S1. Extend the New IE Flags field, and use some bits of this field to identify the number of users:

[0040] A specific embodiment is used to illustrate below. The protocol format can be as figure 2 shown.

[0041] In the New IE Flags field, the meanings of bit0, bit1, and bit7 remain unchanged, and bit6 and bit5 indicate the number of users, that is, the number of subsequent AOAs and Cell Portion LCR IDs.

[0042]

[0043] S2. According to the number of users identified by the above field, load the corresponding number of user azimuths or Cell Portion LCR ID (split cell identification) after the New IE Flags field:

[0044] The FP frame can carry multiple AOA\Cell Portion LCR IDs, a...

Abstract

The invention relates to a method achieving multi-user shaping based on an FP frame extension field. The method achieving the multi-user shaping based on the FP frame extension field comprises the steps that a New IE Flags field is extended, and the number of users is identified by part of bits of the field; according to the number, identified by the field, of the users, user azimuth angles or Cell Portion LCR ID with the number corresponding to the number of the users behind a New IE Flags field is loaded; based on the azimuth angles or the Cell Portion LCR ID, the data of multiple users are loaded through a transmission block. According to the method achieving the multi-user shaping based on the FP frame extension field, multi-user shaping in one TTI is achieved, FACH channel utilization rate is improved, and network capacity is enlarged.

Description

technical field [0001] The present invention relates to the third-generation mobile communication TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), in particular to a method and device for realizing multi-user shaping based on FP frame extension field. Background technique [0002] The TD-SCDMA network has gradually changed from a light-load network to a heavy-load network. When hotspot areas are busy, signaling or business congestion often occurs, and capacity expansion solutions are urgently needed. [0003] At present, FACH data is not omni-directional, but is sent in shape. The base station NodeB notifies the user azimuth angle AOA to the RNC through the RACH FP frame. When sending data, the RNC (Radio Network Controller) notifies the corresponding AOA of the user to the The base station NodeB, and the base station NodeB sends data to the air interface according to the AOA shaping. The benefits of FACH shaping: Obvious gains can be obtained, system int...
