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 present invention provides a multi-channel wireless communication system uplink data transmission method and equipment, including: adjusting the time for sending uplink special frames, so that the radio link control layer RLC feedback time is greater than the two-way time delay; the base station completes the downlink effective data transmission, Before the uplink data arrives, apply for SR resources for scheduling, and use the SR resources and RLC feedback time to perform RLC feedback to the base station; Perform uplink data transmission. The present invention provides a method and device for uplink data transmission in a multi-channel wireless communication system. RLC feedback is performed when valid downlink data is sent. If the terminal applies for SR resources during the two-way delay process, the uplink data can use the The SR resource fed back by the RLC does not require the terminal to re-apply for the SR resource for the uplink data, thus avoiding service delay and improving the timeliness of the system.

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...
