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: A network node, such as an eNB, allocates a PRB allocation for transmission of at least one user-specific RS. The at least one user-specific RS is configured to be transmitted in a pattern. The at least one user-specific RS is transmitted to a UE. The pattern of the at least one user-specific RS includes at least one over-the-edge RS transmitted outside of the PRB allocation. A UE receives at least one user-specific RS in a pattern, and performs channel estimation based on the at least one user-specific RS. At least part of the at least one user-specific RS is in a PRB allocation of the UE and the pattern of the at least one user-specific RS includes at least one over-the-edge RS received outside of the PRB allocation of said UE.

Abstract: Systems, methods, apparatuses, and computer program products for non-linear precoding in radio access networks are provided. One method may include, when it is determined that a user equipment is capable of being non-linearly precoded, determining one of two non-linear precoding modes and indicating the determined non-linear precoding mode to the user equipment. One of the two non-linear precoding modes is configured to use explicit beamformed channel state information, and the other one of the two non-linear precoding modes is configured to use explicit full downlink channel state information.

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: Systems, methods, apparatuses, and computer program products for enhanced link adaptation are provided. One method includes receiving, by a network node, channel state information (CSI) feedback from at least one user equipment (UE), scheduling the same UEs in one rank or more than one rank in the same subframe, and scheduling multiple UEs on at least one same time-frequency resource.

Abstract: According to an example embodiment, an example method may include estimating, by a receiver device in a wireless network, a set of one or more active beams for the receiver device based on an estimated receive power of each active beam to obtain an estimated set of one or more active beams for the receiver device; receiving, by the receiver device, verification information associated with the estimated set of one or more active beams for the receiver device; and, verifying, by the receiver device based on the verification information, the estimated set of one or more active beams for the receiver device.

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: A technique of accounting for the difference in required output power reduction or required duty cycle when selecting the RO in addition to the DL RS. Both output power reduction and duty cycle are independently determined by UE itself (i.e., UE needs to be able to determine itself required power backoff and/or duty cycle in order to meet RF exposure requirements). Advantageously, a RACH procedure in which the UE determines both output power reduction and duty cycle independently enables better choices of output power reduction and duty cycle, enhancing data activity and coverage.

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.
