摘要： There is provided mechanisms for enabling OTA estimation of a radio frequency parameter of a radio transmitter during a test time interval. The radio transmitter is configured for transmission in a set of beams. A method is performed by a controller of the radio transmitter. The method comprises identifying a subset of beams in the set of beams that, during the test time interval, are unused for transmission of scheduled signals. The method comprises instructing the radio transmitter to transmit, during the test time interval, an unscheduled signal in the subset of beams, whilst also transmitting the scheduled signals in those beams of the set of beams that are used for transmission of the scheduled signals, for enabling estimation of the radio frequency parameter of the radio transmitter.

摘要： There is provided mechanisms for performance degradation handling between a first radio access network node that operates in a first frequency band and provides network access for subscribers of a first mobile network operator and a second radio access network node that operates in a second frequency band and provides network access for subscribers of a second mobile network operator. A method is performed by the first radio access network node. The method comprises identifying performance degradation impacting the network access for the subscribers of the first mobile network operator. The performance degradation is identified as originating from a particular direction relative the first radio access network node and as caused by the second radio access network node. The method comprises providing, towards the second radio access network node, an indication of the performance degradation. The indication specifies the particular direction and identifies the second radio access network node as causing the performance degradation.

摘要： A method in anode for achieving Radio Frequency, RF, requirement levels across a set of RF transceivers of a base station, wherein the set of RF transceivers generates one or more Multiple-Input Multiple-Out-put, MIMO, branches. The node groups (606) the one or more MIMO branches into groups of MIMO branches, wherein the one or more MIMO branches in each group of MIMO branches are generated from the same set of RF transceivers. The node generates a combined requirement level by combining (607) a per MIMO branch RF requirements level for the MIMO branches in the group of MIMO branches using a combining function. The node distributes (609) the combined requirement level into a respective individual RF requirement level for each of the respective RF transceivers according to a distribution function.

摘要： A wireless communication node operates using radio resources in a first frequency allocation with a first type of communication configuration and in a second frequency allocation with a second type of communication configuration. An operation control device determines a profile of the interference between transmissions in the two frequency allocations, the interference profile setting out radio resources in at least the first frequency allocation, deemed to be interfered by transmissions in the second frequency allocation, and provides the interference profile for adjusting communication between the wireless communication node and the wireless communication devices for improving communication quality in the first frequency allocation. A wireless communication device in turn adjusts communication settings for the first frequency allocation based on the interference profile.

摘要： The embodiments herein relate to a method performed by a first node (101) for enabling testing of at least a part (105, 108) of the first node (101) in a deployed network. The first node (101) determines that at least a part (105, 108) of the first node (101) should be tested, and determines a direction in which to transmit or receive a test signal (200) to or from a second node (103). The first node (101) transmits the test signal (200) OTA in the determined direction to the second node (103) if a transmitter of the first node (101) should be tested. The first node (101) receives the test signal (200) OTA in the determined direction from the second node (103) if a receiver of the first node (101) should be tested.
