User equipment, base station and methods in a radio communications network

According to a first aspect of embodiments herein, the object is achieved by a method performed by a User Equipment (UE) for monitoring a beam transmitted by a base station in a radio communications network. The base station is serving the UE. The UE monitors a reference signal related to the beam, from the base station. Each time a quality of the reference signal is below a first threshold, the UE generates an Out-Of-Synchronization (OOS) event. When the number of OOS events reaches an OOS Beam Failure Detection (BFD) threshold, the UE triggers a beam recovery preparation procedure, and when the number of OOS events reaches an OOS Radio Link Monitoring (RLM), threshold, the UE starts an RLF timer.

The present disclosure discloses a system including a controller and a plurality of radio heads communicatively coupled to the controller. The controller transmits a synchronization signal to each of the radio heads to synchronize the local clocks in the radio heads to a master clock in the controller. The controller also transmits packets to the radio heads. Each of the radio heads includes a deframer. For a radio head, upon detecting that a received packet from the controller includes an error, the deframer alters the received packet to maintain the synchronization between the controller and the radio head and transmits data contained within the altered packet.

20220353052 · 2022-11-03 · ·

A communication system allows for clock synchronization between a transmitter and a receiver when switching from transmission of an analog signal to transmission of a digital signal. The system uses clock synchronization during transmission of the digital signal, but the clock synchronization may be lost when switching to transmission of an analog signal. A digital clock synchronization is embedded in the analog signal so that the clock synchronization between the transmitter and the receiver may be reestablished upon switching to a digital signal without any delay in transmission of the digital signal.
