Embodiment 1

[0044] In order to solve the problem of relatively large service delay, the first embodiment of the present invention provides a method for uplink data transmission in a multi-channel wireless communication system. The flow chart of the method is as follows figure 1 As shown, the method includes:

[0045] Step 101: Adjust the time for sending the uplink special frame, so that the RLC feedback time of the radio link control layer is greater than the two-way delay;

[0046] Step 102: the base station completes the downlink effective data transmission, and before the uplink data arrives, applies for a scheduling application SR resource, and uses the SR resource and the RLC feedback time to perform RLC feedback to the base station;

[0047] Step 103: When the uplink data arrives and the RLC feedback is not finished, use the SR resource to transmit the uplink data to the base station.

[0048] In the embodiment of the present invention, RLC feedback must be performed when the vali...

Embodiment 2

[0056] The second embodiment of the present invention provides a method for transmitting uplink data in a multi-channel wireless communication system by adjusting the time for sending the uplink special frame, that is, adjusting the RLC feedback time. The method includes:

[0057] Step 301: the base station completes the downlink effective data transmission, and the terminal applies for SR resources for RLC feedback;

[0058] Wherein, after the base station sends valid downlink data to the terminal, the terminal must send RLC feedback to the base station, and report the status of the received valid downlink data to the base station.

[0059] Step 302: the terminal sends RLC feedback to the base station through the applied SR resource;

[0060] Step 303: When the uplink data arrives, but the RLC feedback is not finished, the SR resource is used for uplink data transmission.

[0061] According to the relationship between the two-way delay and the SR period, the time for sending...

Embodiment 3

[0073] The third embodiment of the present invention also provides a terminal device, the flow chart of the device is as follows Figure 7 shown, including:

[0074] An adjustment module 701, configured to adjust the time for sending the uplink special frame, so that the radio link control layer RLC feedback time is greater than the two-way delay, and transmits the RLC feedback time to the feedback module;

[0075] A downlink data receiving module 702, configured to receive downlink valid data transmitted by the base station;

[0076] The application module 703 is configured to apply for a scheduling application SR resource before the uplink data arrives, and transmit the SR resource to the feedback module and the uplink data transmission module;

[0077] The feedback module 704 is configured to use the SR resource and the RLC feedback time to perform RLC feedback to the base station;

[0078] The uplink data transmission module 705 is configured to use the SR resource to tr...

Abstract

The invention provides an uplink data transmission method and equipment for a multi-channel wireless communication system. The uplink data transmission method comprises the following steps: adjusting time for transmitting uplink special frames in order that the radio link control (RLC) feedback time is greater than bidirectional time delay; finishing transmission of downlink effective data through a base station, applying for scheduling request (SR) resources before the arrival of uplink data, and performing RLC feedback on the base station by using the SR resources and the RLC feedback time; and performing uplink data transmission to the base station by using the SR resources at the arrival of the uplink data and before the end of RLC feedback. According to the uplink data transmission method and equipment for the multi-channel wireless communication system provided by the invention, RLC feedback is performed when transmission of the downlink effective data is finished, and the uplink data can use the SR resources of the RLC feedback instead of reapplying SR resources for the uplink data through a terminal if the terminal successfully applies for the SR resources in a bidirectional time delay process, so that service delay is avoided, and the timeliness of the system is enhanced.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for uplink data transmission in a multi-channel wireless communication system. Background technique [0002] In a multi-channel wireless communication system, when a terminal needs to report data, it needs to apply for resources from the base station first. After receiving the command to enable uplink resources, the uplink communication link between the base station and the terminal is established, and the terminal continues to transmit N1 special uplink frames Ending Bsr, inform the other party that the data has been sent, you can close the authorization and recycle resources. [0003] For communication services, the base station starts downlink data transmission through paging, and the terminal applies for uplink authorization through scheduling and requesting SR resources. When the terminal performs uplink communication services, the SR pe...
