Patent number: 11825508Abstract: The invention relates to methods for improving a scheduling request transmission between a UE and a base station. The transmission of the scheduling request is postponed, by implementing a threshold that the data in the transmission buffer has to reach, before a transmission of the scheduling request is triggered. In one variant, the data in the transmission buffer needs to reach a specific amount, to trigger a scheduling request. The invention refers to further improvements: the PDDCH monitoring time window is delayed after sending a scheduling request; the dedicated scheduling request resources of the PUCCH are prioritized differently such that low-priority scheduling requests are transmitted less often.Type: GrantFiled: October 13, 2021Date of Patent: November 21, 2023Assignee: Apple Inc.Inventors: Joachim Loehr, Takahisa Aoyama, Prateek Basu-Mallick, Takashi Tamura, Martin Feuersaenger
