Abstract: An example method, apparatus, and computer-readable storage medium are provided for enabling beam based discovery and direct connectivity using network assisted beam discovery and corresponding signaling to at least reduce sweep time and beam acquisition for D2D discovery operations. In an example implementation, the method may include determining, by a network device of a communication network, information comprising including an indication of at least one of data, a control element, or a relative reference point for identifying a beam sweeping angular spread for device-to-device discovery operations for device-to-device communication. The example method may further include sending towards a set of network nodes the information for the device-to-device discovery in the communication network.

Abstract: A UE, communicating with a network node by using TDD, determines a downlink/uplink configuration between the UE and the network node, and a maximum uplink duty cycle for candidate uplink transmit beam(s). The UE compares the maximum uplink duty cycle with an uplink duty cycle of the determined downlink/uplink configuration, and provides to the network node information associated with the comparison. The network node receives the information associated with the comparison and determines whether to modify the downlink/uplink configuration between the user equipment and the network node based on the information associated with the comparison. The network node indicates, in response to a determination the downlink/uplink configuration should be modified, a modified downlink/uplink configuration to the user equipment.

Abstract: A method and apparatus for dynamically adapting scheduling parameter(s) to achieve power savings. A user equipment may be configured with one or more offsets between scheduled PDCCH and PDSCH transmissions. The user equipment may receive from a network an indication to dynamically change these offsets. If the user equipment sleeps through a first transmission of this indication, upon next receiving the indication the user equipment may update, for example, the offset in a time domain resource allocation table. The indication to dynamically change an offset may be an indication of an offset including fewer slots. A change to the offset, with which downlink transmission is expected by the user equipment, may be disabled. A network node may be configured to transmit downlink traffic to the user equipment according to a configured offset and/or according to an offset the network node indicated to the user equipment.

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).
