Abstract: Various communication systems may benefit from improved performance. For example, communication systems may benefit from a multi-functional reference signal that allows for the harmonization of different reference signal patterns. A method, in certain embodiments, may include constructing at a base station a reference signal including a plurality of reference signal patterns. The plurality of reference signal patterns can include at least one of a default reference signal pattern or a multi-functional signal pattern for at least one of uplink or downlink. The plurality of reference signal patterns can include at least one of partially overlapping or non-overlapping resource elements. In addition, the plurality of reference signal patterns are constructed dynamically for a specific user or group of users. The method may also include sending the reference signal from the base station to a user equipment.

Abstract: Embodiments of the present disclosure disclose devices, methods and apparatuses for uplink transmission. A terminal device measures at least two reference signals from a network device. Moreover, the terminal device transmits, to the network device, a mode indication of uplink transmission for multiple transmission and reception points (m-TRP) based on the measured at least two reference signals. The mode indication indicates information on a preferred one of frequency division multiplexing (FDM) transmission modes. The FDM transmission modes comprise at least a first FDM transmission mode and a second FDM transmission mode.

Abstract: Systems, methods, apparatuses, and computer program products for selecting or prioritizing between a physical downlink shared channel (PDSCH) and synchronization signal block (SSB) reception are provided. One method may include, when outside a SMTC window and when PDSCH resource allocation overlaps with an occupied SSB location, selecting between the PDSCH and SSB reception according to defined rules.

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: 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.
