Abstract: Timing is crucial for next-generation networks at 5G and 6G high frequencies. Disclosed are very brief timing signals, and low-complexity procedures for processing them, to obtain a precision time-base lock between a base station and its user devices. In contrast to conventional modulation, the disclosed timing signals feature a change in modulation centrally positioned in a timing resource element. Since the time boundaries of the resource element at the receiver are determined by the receiver's clock, while the actual time of the timing signal is determined by the base station's clock, a displacement of the received timing signal from the midpoint of the resource element indicates a clock offset between the user device and the base station. In addition, by measuring the interval between successive timing signals, the user device can correct its clock rate, and thereby bring the subcarrier frequencies into agreement with the base station.

Abstract: The random access (RA) procedure in NR-U can be improved by enable the NR-U capable UE to choose a suitable BWP and uses this chosen BWP to perform the RA procedure. A suitable BWP is a BWP with a low probability for LBT failure, such as a BWP having a load that is less than a threshold load. For example, whenever the UE has a RA procedure triggered, the UE selects the most suitable BWP based on load information, such as load measurements made by the UE for one or more available BWPs or load information communicated to the UE. The selected BWP for the RA procedure may be different from the UE's currently active BWP, and, in this case, the UE may do a BWP switch before the RA procedure.
