Scheduling request transmission control method and related products

Abstract

The embodiment of the present invention discloses a scheduling request transmission control method and related products, including: the terminal obtains the reference information of the first parameter that needs to be indicated to the network side device, and the first parameter is a parameter associated with the cached data to be transmitted of the terminal ; The terminal queries the mapping relationship between the preset information of the first parameter and the information of the second parameter of the physical uplink control channel PUCCH resource, and obtains the reference information of the second parameter of the PUCCH resource corresponding to the reference information of the first parameter. The second parameter is a parameter associated with the PUCCH resource used to transmit the SR; the terminal transmits the scheduling request SR used for scheduling buffered data on the PUCCH resource determined by the reference information of the second parameter. The embodiments are beneficial to improving the flexibility of transmitting and calling requests in the wireless communication system, and improving the resource scheduling efficiency of the data transmission channel in the wireless communication system.

Description

[0001] This application is a divisional application of the PCT international patent application PCT / CN2017 / 083105 with the filing date of May 4, 2017, which entered the Chinese national phase with the Chinese patent application number 201780090192.1, and the title of the invention is "Scheduling Request Transmission Control Method and Related Products" . technical field [0002] The present invention relates to the field of communication technology, in particular to a scheduling request transmission control method and related products. Background technique [0003] The fifth-generation mobile communication technology (5th-Generation, 5G) NR is a topic newly proposed in the organization of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP). With the deepening of the discussion of the new generation of 5G technology, on the one hand, because the communication system is backward compatible, the new technology developed later tends to be compatible...

Problems solved by technology

[0012] It can be seen that in the existing LTE MAC layer protocol, SR is triggered by the MAC layer entity and the MAC layer entity instructs the physical layer PHY entity to perform SR transmission on the corresponding (effective) PUCCH resource; and because the scheduling request SR is in the physical layer Layer PHY is only 1bit information, that is, it can only indicate whether the user equipment needs to transmit data to be transmitted, and the network side equipment also needs additional signaling overhead to know the configuration information such as the transmission time interval TTI corresponding to the data to be transmitted, which makes the LTE system The resource scheduling efficiency of SR for data to be transmitted is low, and it is difficult to meet the requirements of future communication systems
