Abstract: Various communication systems may benefit from appropriate configuration of reception states. For example, certain wireless communication systems, such as new radio, may benefit from control monitoring upon receipt of a discontinuous reception trigger. A method can including receiving, by a user equipment, configuration of a search space set of a downlink control resource set with a first monitoring periodicity. The method can also include receiving a trigger or the user equipment becoming active after a period without physical downlink control channel (PDCCH) monitoring. The method can further include, after the receiving of the trigger or the becoming active, modifying a monitoring periodicity of the search space set to a second monitoring periodicity.

Abstract: Systems, methods, apparatuses, and computer program products for managing or monitoring of the control channel in new radio (NR) through blind searches are provided. One method may include configuring, by a network node, multiple search spaces, sets of search spaces, and/or control resource sets, to a user equipment, that results in monitoring occasions where more blind decodings are required than allowed by capability of the user equipment. The method may further include identifying the monitoring occasions for which an allowed number of blind decodings is exceeded, determining a reduced set of blind decodings and/or candidates determined by predefined search space priorities or rules, and transmitting physical downlink control channel(s) to the user equipment given the reduced set.

Abstract: Described are methods for dealing with phase noise, e.g., common phase error and/or inter-carrier interference, in communication systems, and apparatuses for the same. A method can include at least: transmitting one or more reference signals (in-band signals within a channel); and mapping the reference signals to radio resources in the channel for transmission of the reference signals. An amount of the radio resources may depend on, e.g., information about a modulation and coding scheme used for transmission. An associated method can include at least: receiving one or more reference signals, and mapping the reference signals to radio resources in the channel for reception of the reference signals; receiving information about a modulation and coding scheme to be used, an amount of the radio resources depending on, e.g., information about the modulation and coding scheme used for reception; and using the reference signals to compensate for phase noise.

Abstract: A method and apparatus may include determining, by a network node, a plurality of carrier groups. The method may also configuring a user equipment to use the plurality of carrier groups. The method may also include incrementing a downlink assignment index from one scheduled carrier group to another. The downlink assignment index is included with each downlink assignment of a plurality of downlink assignments. The method may also include transmitting the plurality of downlink assignments to the user equipment. Each of the plurality of downlink assignments schedules a downlink channel on a carrier belonging to one of the plurality of carrier groups.
