Abstract: A user equipment, UE, switches between UL BWPs to perform a random access procedure. A base station transmits a configuration specifying multiple UL BWPs on a NUL carrier and a SUL carrier (802). Because the base station selects the configuration for the UE, the base station is aware of the UL BWP which the UE will select as the active UL BWP as well as the UL BWP to which the UE will switch if the UE lacks RACH resources or if the UE decides to switch the between the NUL and SUL carriers. The base station attempts (804) to detect transmission from the UE on the active UL BWP as well as the initial UL BWP of the same NUL (or SUL) carrier.

Some or all of the data processing circuitry operates in a given reset domain other than the reset domain of the transport network. The apparatus also has packet tracking circuitry to monitor the transport packets received at the bridge circuitry and to track whether any required responses have been provided. The reset handling circuitry is responsive to a reset request for the given reset domain to: cause the bridge circuitry to reject new transport packets received for the domain; and when the packet tracking circuitry indicates that all required responses have been provided, accept the reset request for the given reset domain and allow the data processing circuitry to carry out a reset for the data processing circuitry operating in the given reset domain.

Abstract: Some embodiments of the invention provide a method for implementing access controls in a RAN (radio access network) to limit access to base station components of the RAN by RAN applications. The method is performed at a RIC (RAN intelligent controller) that connects the RAN applications to the base station components. The method receives a set of access control data that specifies which RAN applications are allowed to access which base station components. From a particular RAN application, the method receives a data message destined for a particular base station component. Based on the set of access control data, the method determines that the particular RAN application is allowed to access the particular base station component. The method forwards the data message to the particular base station component.
