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 invention provides an uplink data transmission method and equipment for a multichannel wireless communication system. The method comprises the followings steps: adjusting time for transmitting a downlink special frame in order that the sum of the adjusted time for transmitting the downlink frame, time for closing downlink authentication and time for downlink feedback is not smaller than the sum of a scheduling request (SR) period and bidirectional time delay; and receiving uplink data transmitted by using requested SR resources at the arrival of the uplink data through a terminal. According to the embodiment of the invention, the time for transmitting the downlink special frame is adjusted through the uplink data transmission method and equipment for the multichannel wireless communication system in order that the sum of the adjusted time for transmitting the downlink frame, time for closing downlink authentication and time for downlink feedback is not smaller than the sum of the scheduling request (SR) period and the bidirectional time delay, so that the SR resources can be requested rapidly in a service period after the arrival of the uplink data. Therefore, the 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 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...
