20190141645 | ON DEMAND ROUTE SYNCHRONIZATION AND BEAMFORMING IN WIRELESS NETWORKS - Wireless communication is performed by stations (nodes) in a wireless mesh network by forming nodes into a mesh network without the need of network-wide synchronization and without needing to form active links between potential neighbors. Nodes obtain information on neighbors in the network by listening to transmitted beacons from these nearby nodes. Synchronization and active links are established when a data transmission session is triggered and initiated by the route setup process. The link formation process performed when establishing a new route performs both beamforming and synchronization. In situations in which a new route does not intersect other active routes then independent synchronization is performed; but when intersecting routes exist, the new route is synchronized with all intersecting routes where nodes are configured to serve both routes. | 2019-05-09 |
20190141646 | NR WIDEBAND SYNC DETECTION - A network sync signal with unknown frequency location is detected by sampling the received signal over a band of interest in frequency, and over the repetition period of the sync signal in time. The signal is converted to the frequency domain. Sub-bands of the frequency-domain signal, corresponding to different possible sync locations and frequency offsets, are extracted and converted to the time domain, where the sync signal is searched over the reception window length using time-domain matched filtering. | 2019-05-09 |
20190141647 | METHODS OF LIMITED BUFFER RATE-MATCHING (LBRM), PRE-EMPTION, AND SIDELINK SYNCRHONIZATION IN NEW RADIO (NR) SYSTEMS - Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC. | 2019-05-09 |

The first base station then performs frequency synchronization based on the first frequency offset. In some instances, the first base station can determine, through interaction between the first base station and the second base station, the first frequency offset of the first base station without depending on a synchronous Ethernet to perform frequency synchronization. | 2019-05-09 |
