Abstract: According to embodiments, a user equipment (UE) using a first radio of the UE receives from a base station one or more configurations. The one or more configurations indicate resources allocated to wakeup signal (WUS) transmission. The UE using a second radio of the UE detects a WUS in the resources while the first radio of the UE is in a sleep power state. The UE using the first radio performs a wakeup procedure with the base station.

Abstract: A method for indicating a frame structure in a wireless local area network (WLAN) is provided. A sending device generates a transmission frame. The transmission frame includes a physical header. The physical header includes a frame structure indication field. A subcarrier polarity of the frame structure indication field is used to indicate the frame structure of the transmission frame. The sending device sends the transmission frame to a receiving device. In the transmission frame, a first subcarrier polarity indicates the transmission frame has a first frame structure, and a second subcarrier polarity indicates the transmission frame has a second frame structure, so that the receiving device determines the frame structure of the transmission frame according to the subcarrier polarity of the frame structure indication field.

Abstract: A user equipment (UE) may receive, from a base station, a configuration indicating a first orthogonal cover code (OCC) length that is 4 and a second OCC length that is 2 for demodulation reference signals (DM-RSs) communications between the base station and the UE. The UE may receive a signaling indicating the UE to communicate DM-RS(s) according to the first OCC length or the second OCC length. The UE may communicate, with the base station, a DM-RS according to the first OCC length or the second OCC length indicated by the signaling.
