Abstract: Disclosed is a method of operating a Radio Access Network (RAN) including a Radio Unit (RU), a first Distributed Unit (DU), a second DU that functions as a dynamic standby DU, and a network management device. After the RU transmits data to the first DU using a configuration parameter set to an address of the first DU, the RU detects an outage of the first DU. In response to detecting the outage, the RU transmits to the network management device a message indicating detection of the outage. In response, the network management device configures the second DU to perform the functions of the first DU, and causes the second DU to request the RU to set the configuration parameter to an address of the second DU. The RU then uses the configuration parameter set to the address of the second DU to transmit data to the second DU.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing a bandwidth of a user equipment (UE). The UE has a narrower bandwidth part (NBWP) that follows a NBWP hopping pattern and allows the UE to hop frequency over time within a larger bandwidth. The UE receives a configuration of one or more NBWP hopping patterns for one or more configured NBWPs, each configured NBWP having a bandwidth less than or equal to a maximum configurable bandwidth of a bandwidth part. The UE determines an active NBWP hopping pattern for an active NBWP of the one or more configured NBWPs. The UE communicates on frequency domain resources for a frequency domain hop indicated by the active NBWP hopping pattern applied to the active NBWP. The UE may receive an indication of whether to switch the active NBWP hopping pattern.

Each first delay indicates a respective time delay between a resource location of the first downlink control channel and a resource location of a downlink data associated with the first downlink control channel and is configured for a respective first search space of the first search spaces. Each second delay indicates a respective time delay between a resource location of the second downlink control channel and a resource location of an uplink data associated with the second downlink control channel and is configured for a respective second search space of the second search spaces.
