A method and a user equipment of performing resource switching in an unlicensed spectrum are provided. A current set of resources in the unlicensed spectrum is utilized by a UE for performing LBT attempts for transmission of an RACH message to a base station. One or more LBT attempts for transmissions from the UE to the base station are performed over the current set of resources during a current RACH procedure. The current set of resources is switched to a new set of resources in the unlicensed spectrum to be utilized by the UE in a new RACH procedure after a failure count reaches a pre-configured threshold during the current RACH procedure. The failure count is calculated at least based on a count of LBT failure over the current set of resources during the current RACH procedure.

Devices are dynamically paired at a new location based on historical context with respect to previous device pairing and a pairing environment. A request is received at a computer to pair a user device to a device at a new location. Historical context of the user device paired at a previous location to one or more devices at the previous location is analyzed. Pairing of the user device to the device at the new location is automatically initiated based on the analysis of the historical context, and the automatic initiation includes adjusting settings on the user device based on the historical context. Pairing the user device to the device at the new location automatically.

An endpoint computing device multi-network slice remediation/productivity system includes a core network system coupled to a RAN system and configured to allocate network slices and make them available for use in wireless communications via the RAN system. While operating in a pre-boot environment, an endpoint computing device determines that it is unable to transition to operating in a runtime environment and, in response, establishes a remediation network connection with a first network slice, and establishes a productivity network connection with a second network slice. While operating in a pre-boot environment and performing the remediation operations, the endpoint computing device then performs remediation operations via remediation wireless communications over the remediation network connection with the first network slice, and provides access to productivity application(s) that are configured to allow a user to perform productivity operations via productivity wireless communications over the productivity network connection with the second network slice.
