Abstract: Embodiments of the present disclosure relate to reporting beam failure. A terminal device detects a beam failure on one or more serving cells of the terminal device. If the beam failure is detected on the one or more serving cells, the terminal device obtains information concerning one or more candidate beams and the one or more serving cells. Each of the one or more candidate beams is associated with a respective one of the one or more serving cells. The terminal device then transmits at least a portion of the information to a network device associated with the one or more serving cells.

Abstract: Method, apparatus, and computer program product for a user equipment in a wireless communications system to receive configuration information that has one or more TCI-states. With this configuration information, the user equipment can then determine inactivity on TCI-states. Based on that determination, the user equipment enables either a discontinuous monitoring or a cessation of monitoring on those TCI-states. Each TCI-state corresponds to a radio beam and also corresponds to an antenna panel. By reducing such monitoring, the use equipment can deactivate antenna panels corresponding to the TCI-states. The determination can be done through the use of a timer with various time thresholds based on the TCI-state. The activity being transmitted on those beam can be scheduling received by the user equipment from a network element such as a base station. The TCI-states can also be grouped and the functionality of the invention dealt with on a group basis.

Abstract: A method may include receiving, from a network node, association and configuration information for a plurality of sequences, where each sequence may be associated to at least one network-node beam or beam-pair link. The method may also include performing beam measurements of beams from the network node to obtain beam measurement information. The method may further include detecting beam misalignment of the beam based on the beam measurement information. In addition, the method may include transmitting a sequence among the plurality of sequences to the network node to inform the network node of the beam misalignment, and to trigger the network node to start a beam adjustment procedure and a monitoring procedure for a configured-grant configuration. Further, the method may include, after transmitting the sequence, considering the indicated preferred beam as a new serving beam, and switching to the configured-grant configuration associated with this new serving beam.

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: When a time domain collision between Tracking Reference Signal (TRS) symbols and downlink shared data channel symbols is detected, the TRS symbols may be multiplexed with the downlink shared data channel symbols from multiple Transmission Reception Points (TRPs) not sharing quasi co-location (QCL) parameters with each other. If a time domain collision between TRS symbols and dynamically or semi-static (e.g., persistent) downlink shared data channel transmissions is detected, transmission and/or reception of the TRS and/or the downlink shared data channel may be adjusted.

Abstract: Various communication systems may benefit from time discontinuous transmission. For example, narrow band Internet of things (NB-IoT) may benefit from having transmissions with sufficient time diversity to avoid unnecessary repetition. A method can include configuring a control channel and data channel partitioning pattern within a configured time period. The method can additionally include communicating with at least one user equipment based on the control channel and data channel partitioning pattern.

Abstract: Various example embodiments relate to apparatuses and methods for inter-cell beam management. An apparatus may be configured to support a first control resource set and a second control resource set for a serving cell, receive a transmission configuration indicator state indication for the first control resource set for a cell other than the serving cell, and ignore, for the second control resource set, the received transmission configuration indicator state indication when the second control resource set is configured to follow a transmission configuration indicator state indication for the serving cell.
