Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently selecting resources for sidelink communications in a shared spectrum while allowing other user equipment (UEs) a chance to gain access to the shared spectrum. In one aspect, a UE may transmit sidelink data to another UE in accordance with a frequency hopping pattern to randomize interference and improve throughput. According to some aspects, the first UE may transmit the sidelink data on a first set of interleaved frequency resources in a first time interval and a second, different set of interleaved frequency resources in a second time interval. In another aspect, a UE may rely on feedback from other UEs to determine when reserved resources are released, and the UE may use the released resources for sidelink communications.

Radio access network latency data corresponding to a measured latency impact criterion is obtained by a network device of a wireless network. Based on the radio access network latency data, latency guidance data usable by the radio network device to achieve a reduction in communication latency that is experienced by a user equipment is predicted, e.g., by a learned model. The latency guidance data can be used to facilitate a reduction in the communication latency that is experienced by a user equipment.

First wireless device sends second data with the second schedule to the second AP device and communicates a data frame with a device connected to the first wireless device according to the second schedule.

Abstract: Aspects of the disclosure relate to a user equipment (UE) for wireless communication. The UE wakes to monitor for a wakeup signal (WUS) having a maximum WUS duration and configured to indicate an upcoming transmission of a paging signal corresponding to the WUS. The UE detects a reference signal tone energy from tones carrying reference signals, detects a WUS tone energy from tones designated for carrying the WUS, and determines whether the WUS is present or absent based on the WUS tone energy and the reference signal tone energy. The UE then transitions to a sleep state prior to an end of the maximum WUS duration when the WUS is determined to be absent. Alternatively, the UE remains awake when the WUS is determined to be present and receives the paging signal corresponding to the WUS. Other aspects, features, and embodiments are also claimed and described.
