Abstract: Certain example embodiments provide systems, methods, apparatuses, and computer program products for a handover of a coordinated multi-point connection. For example, certain embodiment may transfer a first coordinated multi-point connection (e.g., a further enhanced multiple input multiple output (FeMIMO) connection) to a second coordinated multi-point connection where the network may instruct the UE to not perform at least one random access procedure. The first coordinated multi-point connection may be controlled by a first cell (the serving cell) where the UE is ready to receive from and transmit to a first set of cells that comprises the serving cell and one or more non-serving cells. After handover, the second coordinated multi-point connection may be controlled by a previous non-serving cell, and the UE may be ready to receive from and transmit to a second set of cells that comprises the previous non-serving cell.

Abstract: An apparatus in a communications device includes circuitry configured for determining one or more parameters for one or more downlink signals received by a plurality of antenna arrangements of a set of antenna arrangements and for causing the communications device to transmit to an access point using a subset of said set of antenna arrangements, the subset of said set of antenna arrangements being selected on the determined one or more parameter.

Abstract: A method including configuring a first radio beam pair and at least a second radio beam pair to a communication connection, wherein the first radio beam pair includes a first transmission radio beam having a first transmission direction and the second radio beam pair including a second transmission radio beam having a second transmission direction different from the first transmission direction; triggering channel contention to transmit at least one message from the apparatus and performing radio channel sensing for both the first transmission radio beam and the second transmission radio beam during the channel contention; acquiring a transmission opportunity in response to detecting that a radio channel is available for at least one of the first transmission radio beam and the second transmission radio beam; and causing transmission of the at least one message during the transmission opportunity.

Abstract: Systems, methods, apparatuses, and computer program products for applying beam diversity for multi-slot physical downlink shared channel (PDSCH) are provided. One method may include receiving configuration of a multi-slot transmission mode for a multi-slot communication channel. The method may also include receiving, based on the configuration of the multi-slot transmission mode, transmission configuration indications of a plurality of transmit beams for slots in the multi-slot communication channel. A selected set of candidate transmit beams may be received among the plurality of transmit beams for the slots in the multi-slot communication channel. The method may also include determining, among the selected set of candidate transmit beams, which transmit beam is used for each slot in the multi-slot communication channel, and applying a reception beam corresponding to each transmit beam used for each slot in the multi-slot communication channel.

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.
