Abstract: In order to provide a communication system and the like which are capable of updating a correction value of a time synchronization packet, and to which a traffic bonding scheme is applied, a set of primary devices of the communication system determines presence or absence of communication in a first transmission path, adds an actual measurement value of a first delay amount to an information value when a determination result according to the determination is that the communication is present, or adds, to the information value, a design value of a second delay amount being the delay amount inside the wireless transmission device and the wireless reception device when the determination result is that the communication is absent.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured with a frequency hopping pattern for communication between the UE and a base station, and also may be configured with a measurement gap pattern for measurement of one or more reference signals from one or more neighboring base stations. One or more switching timings of a set of switching timings of the frequency hopping pattern may be aligned with a reference point associated with the measurement gap pattern, which may provide aligned switching gaps in the frequency hopping pattern and the measurement gap pattern.
