Embodiment 1

[0042] 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:

[0043] Step 101: Adjust the time for sending the downlink special frame, so that the sum of the adjusted time for sending the downlink special frame, the time for closing the downlink grant and the time for downlink feedback is not less than the sum of the scheduling application SR cycle and the two-way delay;

[0044] Step 102: receiving the uplink data transmitted by the terminal using the applied SR resource when the uplink data arrives.

[0045] In the embodiment of the present invention, the time for sending the downlink special frame is adjusted so that the sum of the adjusted time for sending the downlink special frame, the time for closing the downlink grant and the time for...

Embodiment 2

[0053] 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 a downlink special frame, the method comprising:

[0054] Step 301: the base station completes the downlink effective data transmission, and the terminal performs RLC feedback to the base station;

[0055] 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.

[0056] Step 302: Adjust the time for sending the downlink special frame, so that the sum of the adjusted time for sending the downlink special frame, the time for closing the downlink grant and the time for downlink feedback is not less than the sum of the SR period of the scheduling application and the two-way delay;

[0057] Step 303: Before the uplink data arrives, the terminal appl...

Embodiment 3

[0065] The third embodiment of the present invention provides a base station, such as Figure 4 shown, including:

[0066] The adjustment module 401 is configured to adjust the time for sending the downlink special frame, so that the sum of the adjusted time for sending the downlink special frame, the time for closing the downlink grant and the time for downlink feedback is not less than the sum of the SR period and the two-way delay, and transmit the adjusted total time of the sum of the time for sending the downlink special frame, the time for closing the downlink grant and the time for downlink feedback to the uplink data receiving module;

[0067] The uplink data receiving module 402 is configured to receive the uplink data transmitted by the terminal using the applied SR resource when the uplink data arrives.

[0068] Further, the base station also includes:

[0069] The uplink data receiving module is also used to receive the radio link control layer RLC feedback that ...

Abstract

The present invention provides a method and device for uplink data transmission in a multi-channel wireless communication system, including: adjusting the time for sending downlink special frames, so that the adjusted time for sending downlink special frames and the time for closing downlink authorization and the time for downlink feedback The sum is not less than the sum of the scheduling application SR cycle and the two-way delay; when the uplink data arrives, the receiving terminal uses the applied SR resource to transmit the uplink data. The embodiment of the present invention provides a multi-channel wireless communication system uplink data transmission method and device, and adjusts the time for sending the downlink special frame, so that the adjusted time for sending the downlink special frame, the time for closing the downlink authorization, and the time for downlink feedback The sum is not less than the sum of the scheduling application SR cycle and the two-way delay, so that the uplink data can quickly apply for SR resources during the business period after the arrival of uplink data, thus avoiding business delays 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 there is a downlink communication service, the base station first needs to page the terminal, and then send a command to enable downlink resources. The downlink communication link between the base station and the terminal is established. After the downlink service transmission is completed, the base station Continue to transmit N2 downlink special frames Ending Bsr (Buffer Status Report, buffer status report), to ensure that the terminal extends the data transmission status of several frames, so as to avoid the terminal's uplink and downlink business transmission soon; when the terminal needs to report data, it needs First apply for resources from the base station, and after receivi...
