Title: SIGNALING ASPECTS OF MULTIPLE SR CONFIGURATION FOR SERVICE DIFFERENTIATION
Abstract:
A base station (11) configures a terminal (31) with two or more Scheduling Request (SR) configurations. Each SR configuration includes at least one of time and frequency domain resources for a SR, based on information associated with logical channels (LCH). From a received SR transmitted according to a SR configuration, the base station (11) may ascertain that the terminal (31) has data to transmit; the LCH triggering the SR; a priority for each LCH; and/or a set of the numerologies/TTI durations associated with each LCH. Methods disclosed herein provide a signaling alternative for the network to signal multiple SR configurations; provide means for the network to activate/deactivate certain configurations; provide means for the network to switch from one configuration to another one, and signal to the terminal (31); and provide means for the terminal (31) to signal configurations from the terminal's preference perspective.
