Abstract: A method includes determining whether a downlink beam signal is being received from a base station (502); when the downlink beam signal is being received from the base station, determining whether a measurable property of the downlink beam signal does not meet a preselected threshold (504); when the downlink beam signal is not being received from the base station or when the measurable property of the downlink beam signal does not meet the preselected threshold, transmitting a message to the base station indicating that at least one uplink beam corresponding to the downlink beam has failed (506); and receiving a reply message from the base station with information required to determine a new uplink beam (508). An alternative method includes determining whether at least one uplink beam signal is being received from a user equipment (602); determining whether a measurable property of the at least one uplink beam signal does not meet a preselected threshold, when the at least one uplink beam signal is being received from the user equipment (604); and transmitting a message to the user equipment to initiate uplink beam recovery, when at least one uplink beam signal is not being received from the user equipment or when the measurable property of the at least one uplink beam signal does not meet the preselected threshold (606).

Abstract: A method comprises: configuring multiple reporting modes for multi-level based transmitter (TX) beam index reporting for a particular beam/antenna panel group from a plurality of beam/antenna groups, wherein the multiple reporting modes includes at least one of a full reporting mode configuration for the particular beam/antenna panel group, a full reporting mode configuration common for the plurality of beam/antenna panel groups, a differential reporting mode, and a partial reporting mode, selecting a reporting mode from the multiple reporting modes, and sending a report based on the selected reporting mode.

Abstract: A method is provided where handover information about one or more target beams of a target cell is provided. The beam quality of those target beams is determined along with beam quality of one or more other beams of the target cell. Dedicated uplink resources associated with the target beams and shared uplink resources are associated with the other beams. It is determined based on the beam quality which of the target and other beams is to be used to initiate a connection to the target cell.

Abstract: Various communication systems may benefit from improved network communications. For example, messages sent to a user equipment may benefit from having optional configurations of parameters. A method includes determining optional configurations for parameters that override or supplement a default configuration of the parameters. The optional configurations are grouped into optional parameter groups. The method also includes encoding at least one of the optional parameter groups in a message. In addition, the method includes transmitting the message from the network node to a user equipment.
