Abstract: In a general aspect, various fields of a PHY frame are used for motion detection. In some aspects, a first training field and a second, different training field are identified in a PHY frame of each wireless signal transmitted between wireless communication devices in a wireless communication network. A first time-domain channel estimate and a second time-domain channel estimate are generated for each wireless signal. The first time-domain channel estimate is based on a first frequency-domain signal included in the first training field, while the second time-domain channel estimate is based on a second frequency-domain signal included in the second training field. A determination is made whether motion has occurred in a space during the time period based on the first time-domain channel estimates, and a location of the motion within the space is determined based on the second time-domain channel estimates.

Abstract: A second RAN node (2) associated with a second RAT sends a radio resource configuration of the second RAT to a radio terminal (3) via a first RAN node (1) associated with a first RAT. The radio resource configuration explicitly or implicitly indicates at least one numerology that is included in multiple numerologies supported by the second RAT and is different from a reference numerology. It is thus, for example, possible to allow a radio terminal to be configured with a numerology of a cell served by a secondary gNB or a target gNB in Inter-RAT Dual Connectivity between E-UTRA and NR and in a handover from E-UTRA to NR.

Abstract: Aspects of the present disclosure relate to transmitting prioritized path data to a device based on a set of topology rules and metrics associated with a storage target. A storage target path discovery request is received from the device. In response to the storage target path discovery request, metrics associated with the storage target are collected. Based on the collected metrics, available paths to the storage target are identified. A set of topology rules are then determined. Based on the topology rules and the collected metrics, a subset of available paths are selected. The subset of available paths are then prioritized into prioritized path data. The prioritized path data is then stored and transmitted to the device.

Abstract: Disclosed is a method of transmitting/receiving a signal by a transmission device in a mobile communication system. The method includes: receiving information related to synchronization signals from a Base Station (BS); transmitting a first synchronization signal based on the received information; and receiving a second synchronization signal corresponding to the first synchronization signal based on the received information. When a UE cannot receive a synchronization signal from the BS or is located beyond a coverage of the BS, or when the BS cannot operate due to an emergency or disaster situation, UEs can configure self synchronization therebetween in a predetermined area without any assistance from the BS and thus broadcast and unicast transmission are possible between the UEs based on the synchronization.

The sequence hopping is performed using a pseudo-random function, and the sequence hopping is performed in a unit of a slot.

After the amount of time has elapsed, a second indication that the first network device has exited the state is sent to the second network device. A topology of the network is updated after the first network device has exited the state.
