摘要： Route selection through a wireless mesh network between a source node and a destination node is based on minimizing generated interference in order to increase the capacity of the network. An interference energy associated with transmitting a packet over each hop in multiple routes from the source node to the destination node is determined. The interference energy for each hop is combined to generate a combined interference energy for each route. One of the routes is selected based on the combined interference energy determined for each route.

摘要： A network node (110) and a method for transmitting a Transmission Configuration Indication, TCI, update to a UE (120). The network node associates a first transmit beam with a first reference signal having first Quasi Co-Location, QCL, channel properties. The first transmit beam gives the same first QCL channel properties and is used in data transmission to the UE. Further, the network node determines second QCL channel properties given by a second transmit beam when a beam change is triggered. When the second QCL channel properties is within a QCL channel property range of a second reference signal and when the second reference signal has third QCL channel properties being different from the first QCL channel properties, the network node associates the second transmit beam with the second reference signal, and transmits, to the UE, a TCI update comprising an indication of the second reference signal.

摘要： In SIB2 there is an entry containing information on PUSCH power control parameters. The current signaling entity is extended with entries that are dependent on UE operational altitude. For example, an altitude-dependent factor for the alpha parameter, or one parameter range for zero (ground level, default as per of today), one parameter range for intermediate altitude operation, and one entry for high-altitude operations, so that an airborne UE can select its appropriate power control parameters.

摘要： Method performed by a first node (101) for managing a movement of a radio antenna (120). The first node (101) operates in a wireless communications network (100). The first node (101) determines (302) whether the movement of the radio antenna (120) is above a threshold over a time period. The radio antenna (120) is connected to a second node (102) operating in the wireless communications network (100). The movement is with respect to at least one wireless device (140) operating in the wireless communications network (100). The determining (302) is based on an analysis of one or more properties of radio transmissions to or from the radio antenna (120) over the time period. The first node (101) initiates (304) providing a message to one of: the second node (102) and a third node (103) operating in the wireless communications network (100). The initiation is based on a result of the determination.
