Method, apparatus and terminal for implementing uplink scheduling information sending

Abstract

The present invention provides a method for realizing the transmission of uplink scheduling information, wherein the method comprises the following steps: generating uplink scheduling information; confirming the transmission mode of uplink scheduling information according to the existence state of scheduling permission and non-scheduling permission; and transmitting the uplink scheduling information with a confirmed transmission mode. The invention also provides a device for realizing the transmission of uplink scheduling information and a terminal thereof. The method, device and terminal according to the invention determine the scheduling transmission mode, non-scheduling mode and random access enhancement mode through the comparing of time delay and expenditure and the principles of uplink synchronous requirement, and select an optimal mode for transmitting the uplink scheduling information. The method, device and terminal of the invention have the advantages of optimizing the transmission process of uplink scheduling information, reducing the time delay of uplink scheduling information, guaranteeing the resource usage factor in a certain extent and increasing the transmission success rate of uplink scheduling information.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 200810056326.0 and the title of the invention "a method, device and terminal for realizing the transmission of uplink scheduling information" submitted to the China Patent Office on January 16, 2008, the entire content of which is passed References are incorporated in this application. technical field [0002] The present invention relates to the technical field of mobile communication, in particular to a method, device and terminal for realizing the transmission of uplink scheduling information. Background technique [0003] At present, in the HSUPA (High Speed ​​Uplink Packet Access) technology of the TDD (Time Division Duplex) system, when the terminal has uplink data to send or the buffer size on the terminal side is greater than 0, if there is no permission at this time, it needs to pass E-RUCCH The (enhanced random access control channel) channel sends an uplink sc...

Problems solved by technology

[0004] However, in the current HSUPA protocol, when there is a license, it is not clearly distinguished whether the license is a license for scheduled transmission or a license for non-scheduled transmission, and the scheduled transmission mode can transmit uplink scheduling information, and the non-scheduled transmission mode can also transmit Uplink scheduling information can be transmitted; although the uplink scheduling information itself is only used to indicate the buffer status of the logical channel mapped to the scheduled transmission, and the measurement information in the uplink scheduling information is also used to help the base station schedule the data mapped to the scheduled transmission mode However, the unscheduled transmission resources corresponding to the unscheduled transmission grant are allocated by the RNC (radio network controller), and the unscheduled transmission resources are generally configured in the form of discontinuous resources, that is to say, multiple users time-division Reuse the same time slot and code channel resources, so if the interval between non-scheduled resources of the terminal is large, that is, when the time interval between adjacent non-scheduled resources is large, according to the method defined in the current protocol, the terminal needs to wait for a long time The uplink scheduling information cannot be sent until the time when the non-scheduling resources take effect, so the sending method of uplink scheduling information according to the current agreement will bring a large delay

[0005] In addition, when the terminal has a scheduled transmission license and a non-scheduled transmission license at the same time, the current protocol and the prior art do not clearly define how the terminal selects the transmission mode of SI (uplink scheduling information) information from the two types of licenses ; When the terminal receives an RDI (Resource Persistence Indication) permission and configures non-scheduled transmission resources at the same time, if only the transmission method of the uplink scheduling information is selected according to the minimum delay, then when the resource amount of the non-scheduled permission is small Or when the resource amount of the scheduling permission is small, the uplink scheduling information with few bits may occupy a large overhead;

[0006] To sum up, in the triggering method of sending uplink scheduling information in the prior art, only two cases of permission and no permission are distinguished, and the situation of permission is not divided into scheduling permission and non-scheduling permission; therefore, if there is only non-scheduling permission When the resource interval of the scheduling grant and the allocated non-scheduling grant is large, sending uplink scheduling information through the non-scheduling grant will cause a large delay; in addition, when there are both scheduling grants and non-scheduling grants It is not clear how to send the uplink scheduling information
