Embodiment 1

[0042] According to an embodiment of the present invention, a resource allocation method for real-time service transmission is provided, which is used for a base station to allocate service channel resources for real-time service transmission to a terminal, wherein there is a resource allocation control channel between the terminal and the base station.

[0043] Specifically, the method may include the following processing:

[0044] (1) The base station allocates semi-static traffic channel resources for the terminal through the resource allocation control channel for the initial HARQ transmission of real-time service data packets; wherein, the terminal can continue to use the semi-static traffic channel resources before the base station reconfigures or releases the semi-static traffic channel resources Semi-static traffic channel resources;

[0045] (2) The base station allocates dynamic service channel resources for the terminal through the resource allocation control channe...

Embodiment 2

[0049] According to an embodiment of the present invention, a real-time uplink service transmission method is provided, which is used for real-time uplink service transmission between a terminal and a base station, wherein a resource allocation control channel and an information feedback control channel exist between the terminal and the base station.

[0050] Image 6 It is a flow chart showing a downlink real-time service transmission method according to an embodiment of the present invention. Such as Image 6 As shown, the uplink real-time service transmission method according to the embodiment of the present invention includes the following processing (step S602-step S610):

[0051] Step S602, the base station allocates semi-static traffic channel resources to the terminal; wherein, before the base station reconfigures or releases the semi-static traffic channel resources, the terminal can continue to use the semi-static traffic channel resources;

[0052] Step S604, the...

Embodiment 3

[0088]According to an embodiment of the present invention, a downlink real-time service transmission method is provided, which is used for downlink real-time service transmission between a terminal and a base station, wherein a resource allocation control channel and an information feedback control channel exist between the terminal and the base station.

[0089] Figure 8 It is a flow chart showing a downlink real-time service transmission method according to an embodiment of the present invention. Such as Figure 8 As shown, the downlink real-time service transmission method according to the embodiment of the present invention includes the following processing (step S802-step S810):

[0090] Step S802, the base station allocates semi-static traffic channel resources to the terminal; wherein, before the base station reconfigures or releases the semi-static traffic channel resources, the terminal can continue to use the semi-static traffic channel resources;

[0091] Step S8...

Abstract

The invention discloses a resource allocation method transmitted by real-time business and uplink / downlink real-time business transmission method; in the uplink real-time business transmission method, a base station allocates semi-static business channel resource for the terminal; the terminal uses the semi-static business channel resource to execute the initial transmission of mixed automatic retransmission request of the business package; the base station receives the semi-static business channel resource and judges whether the initially transmitted real-time business package is right, if not, allocates dynamic business channel resource for the terminal; the terminal uses the dynamic business channel resource to retransmit the real-time business package; the base station receives the dynamic business channel resource to judge whether the retransmitted real-time business package is right, if not, allocates the dynamic business channel resource for the terminal under the condition that the retransmission times do not achieve the preset threshold value.

Description

technical field [0001] The present invention relates to real-time service transmission and resource allocation thereof in a synchronous wireless communication system, in particular to a resource allocation method for real-time service transmission and an uplink / downlink real-time service transmission method. Background technique [0002] In order to provide higher-speed uplink and downlink packet services and improve spectrum utilization efficiency, 3GPP (3rd Generation Partnership Project) introduced High Speed ​​Downlink Packet Access (HSDPA for short) in the TD-SCDMA system specification and High Speed ​​Uplink Packet Access (HSUPA for short) features, and by introducing Adaptive Modulation and Coding (AMC for short), Hybrid Automatic Retransmission Request (HARQ for short) and The scheduling technology controlled by Node B (Node B) reduces the network processing delay, thereby improving the uplink / downlink packet service rate and spectrum utilization efficiency.
