Abstract: Various communication systems may benefit from improved handover. For example, it may be helpful to manage a list candidate cells to which a user equipment may be handed over. A method may include receiving at a user equipment a list of prepared candidate cells from a source cell. The method may also include transmitting the list of prepared candidate cells from the user equipment to a target cell after or during handover from the source cell to the target cell.

Abstract: Methods, apparatuses, and computer program products where a user equipment in a wireless communications network determines a measure of signal quality for a restricted set of beam recovery candidates, compares the measure of signal quality of contention free random access candidates reference signal in the restricted set or a subset of contention free random access candidates to a signal quality based recovery threshold, and selects the at least one candidate signal with signal quality above that threshold from a candidate beam reference signal list; where the user equipment measures a reference signal received power for contention free random access candidate beam, selects candidates above a reference signal received power threshold, determines signal quality for the selected contention free random access candidates above that threshold, and selects one candidate in response to multiple contention free random access candidates being above that threshold or the one with highest measure of signal quality.

Abstract: Embodiments of the present disclosure relate to uplink control information for uplink information based on wake-up signals. According to embodiments of the present disclosure, the terminal device determines based on transmission information at a first time point whether a predetermined number of the one or more occasions overlaps with active time of the terminal device. The terminal device determines the configuration for transmitting the uplink information based on the determination. In this way, ambiguity has been reduced and the flexibility of the network is improved.

Abstract: A method and apparatus for providing multi-beam downlink channel control procedures. The invention allows for power savings at a user device by indicating what states are to be used and/or indicating deactivation of receiver panels. This is accomplished, at least partially, through the use of a transmission configuration indication table based, at least partially, on measurements made by a user device and panel tags indicating the panels used to make those measurements. Determining optimal downlink and uplink beam selection is accomplished with reference to user device measurements and reporting.

Abstract: To better support beamforming in MIMO systems such as 5G, a first match is determined between a first transmit (TX) beam group of a radio network and a first receive (RX) beam group of a user equipment (UE); and also a second match is determined between a second TX beam group of the radio network and a second RX beam group of the UE. For example these matches can come from the UE's beam report with best match information. The network configures the UE with at least a first discontinuous reception (DRX) configuration associated with the first RX beam group and with a second DRX configuration associated with the second RX beam group. In this case the first and second DRX configurations are active simultaneously for the UE, and each said beam group comprises at least one antenna or antenna port.

Abstract: A method can include transitioning, by a device, from a sleep state to a monitoring state, processing, during the monitoring state, a wakeup signal, determining an adaptation based on the wakeup signal, transitioning to an active state after processing the wakeup signal, and extending the active state based on the determined adaptation.

Abstract: Determination of characteristics of a communication environment may be beneficial in many communication systems. For example, certain wireless communication systems, such as fifth generation (5G) communication systems, may benefit from appropriate mobility measurements. A method can include performing, at a user equipment, beam-specific measurements of a plurality of beams of at least one cell. The method can also include calculating a cell quality based on the beam-specific measurements.

Abstract: An apparatus for a terminal has means for storing a first configuration for measurement reporting on downlink reference signals, wherein one or more downlink reference signals correspond to one of a plurality of states for a first channel. The apparatus also has means for receiving an activation of a first state of the plurality of states for the first channel, and determining a second configuration for measurement reporting based on the first configuration for measurement reporting and the received activation of the first state, wherein the second configuration for measurement reporting configures the terminal to report measurements on a first downlink reference signal corresponding to the first state.
