Abstract: Facilitation detection of control channels with different transmission time intervals (TTIs) in wireless communications systems is described herein. In one example, a computer-implemented method comprises: monitoring, by a mobile device comprising a processor, a first control channel in the beginning of a first TTI; and receiving, by the mobile device, a first downlink control information (DCI) on the first control channel in the first TTI, wherein information of the first DCI indicates a pattern of a second TTI associated with a second control channel, and wherein the second control channel occurs later than the first control channel and the second TTI is shorter than the first TTI. The computer-implemented method can also comprise determining, by the mobile device, whether to monitor the second control channel of the second TTI based on the information of the first DCI.

Abstract: Methods and apparatuses for handling device-to-device feedback transmission in a wireless communication system are disclosed herein. In one method, a first device receives a configuration for operating in a network scheduling mode for acquiring sidelink resources. The first device receives a sidelink control information with a report request from a second device. The first device triggers or is triggered to transmit a report to the second device in response to the report request. If the first device has no available sidelink resource for transmitting the report, the first device triggers a scheduling request. The first device transmits a signaling of the scheduling request to the network. The first device receives a sidelink grant from the network. The first device utilizes sidelink resource(s) indicated by the sidelink grant to transmit the report to the second device.
