Abstract: Methods and apparatus for base station conformance testing are disclosed. Two wireless carriers that are based on different radio technologies and dynamically share a radio spectrum are received from a base station. Frequencies and timings of the two wireless carriers are measured and a frequency difference between the measured frequencies and a timing difference between the measured timings of the two wireless carriers are then determined. It can then be determined whether the frequency and timing differences satisfy predefined criteria for acceptable frequency and timing differences.

Abstract: The present subject matter relates to a method for operating a node of a communication system. The node is configured to support wireless backhauling in the communication system and support wireless access to user equipments of the communication system. The method comprises: using at least one test configuration for concurrently testing data transmission on a backhaul link and an access link of the node.

Abstract: According to a first embodiment, a method may include calculating at least one moving average window size in a frequency domain associated with a channel bandwidth and adjusting the at least one moving average window size in the frequency domain for at least one demodulation reference signal subcarrier in at least one resource block where at least one gap having a size of at least a predefined size is between the at least one resource block. The at least one resource block comprises a predetermined number of demodulation reference signal subcarriers.

Abstract: A fault-tolerant data processing computer system and method for implementing a distributed two-tier state machine aimed for distributed (replicated) data stores, in which consistency is maintained despite the failure of any number of replicas and communication paths. In the distributed two-tier state machine, one process (device) in a network of processes (devices) is chosen as the leader, and that leader is responsible for executing functions that return state machine commands, and for broadcasting the commands to the other processes. The processes execute the commands in the logical precedence order that corresponds to the order of function executions that return these commands. The system and method ensures that each of the processes issues exactly the same sequence of commands for execution, such that each command in the sequence, except the first one, has a precedent command on which the command logically depends.
