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: 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: Various communication systems may benefit from appropriate assumptions regarding physical or electrical characteristics of the systems. For example, fifth generation (5G) or similar communication systems may benefit from appropriate antenna co-location and receiver assumptions. A method can include receiving an indication of a set of co-location rules to apply from at least three sets of co-location rules. The method can also include applying the indicated set of co-location rules.

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.

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.
