摘要
Disclosed are a scheduling request transmission control method and a related product. In the method, a terminal acquires reference information about a first parameter needing to be indicated to a network side device, wherein the first parameter is a parameter associated with cached data to be transmitted of the terminal. The terminal queries a pre-set mapping relationship between information about the first parameter and information about a second parameter of a physical uplink control channel (PUCCH) resource, and acquires reference information, corresponding to the reference information about the first parameter, about the second parameter of the PUCCH resource, wherein the second parameter is a parameter associated with the PUCCH resource for transmitting a scheduling request (SR). The terminal transmits the SR for scheduling the cached data on the PUCCH resource determined by means of the reference information about the second parameter.

This is a continuation application of International Patent Application No. PCT/CN2017/083105, filed on May 4, 2017, the contents of which are hereby incorporated by reference in its entirety.
The 5th-Generation (5G) New Radio (NR) is a subject raised recently by the 3rd Generation Partnership Project (3GPP). With increasingly deep discussions about a 5G technology, on one hand, because of backward compatibility of a communication system, a new technology researched and developed later tends to be compatible with a technology which has been standardized before; and on the other hand, because of existence of numerous existing designs for 4th Generation (4G) mobile communication Long Term Evolution (LTE), flexibility of 5G may inevitably be sacrificed for compatibility to further bring reduction in performance. Therefore, researches in two directions are concurrently made by the 3GPP at present. Herein, the technical discussion group not considering backward compatibility is called 5G NR.
