Abstract: Systems, methods, apparatuses, and computer program products for beam group-based downlink transmit beam indication. Certain embodiments may provide enhancements related to physical layer design for multiple input multiple output and/or enhancements for a beam indication framework for scenarios with multiple transmission reception points and user equipment equipped with multiple antenna panels. A network node may transmit, and a user equipment may obtain, information indicating that one or more activated transmission configuration indictor states are associated with a set of beam groups.

Abstract: An apparatus comprising: at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: determine (1006) whether at least one transport block has been successfully delivered to another apparatus; and determine (1008, 1010, 1012) whether to use the at least one transport block to scramble at least one subsequent transport block based on whether the at least one transport block has been successfully delivered to the apparatus.

Abstract: Systems, methods, apparatuses, and computer program products for multiple transmission-reception point (M-TRP) operation after beam failure recovery (BFR) are provided. One method may include determining, by a UE, that a beam failure detection (BFD) reference signal or signals (RS) associated with one or more beam failure detection resource sets has failed. The method may also include determining, by the UE, that it is not required to monitor a channel on at least one control resource set (CORESET) associated with an index value that is further associated with the one or more failed beam failure detection resource sets.

Abstract: Systems, methods, apparatuses, and computer program products for multiple transmission-reception point (multi-TRP) physical uplink control channel (PUCCH) scheme determination are provided. One method may include receiving, at a user equipment, at least one of an indication or configuration comprising information relating to one or more multi-TRP PUCCH schemes. The method may also include determining a multi-TRP scheme to apply for an uplink control information (UCI) transmission using at least one of the indication or the configuration, and transmitting the UCI on PUCCH according to the determined multi-TRP PUCCH scheme.

Abstract: A distributed unit, DU, of a radio access node configured to operate in a scenario where the DU is one of multiple DUs serving links to a multi-connected entity, acquires a first DU radio resource configuration for the DU, acquires a first link radio resource configuration corresponding to a first link of a multi-connectivity link of a multi-connected entity, wherein the first link is served by the DU, acquires a multiplexing configuration of the multi-connectivity link, and determines availability of at least one radio resource for the multi-connectivity link based on the first DU radio resource configuration, the first link radio resource configuration, and the multiplexing configuration.

Abstract: In accordance with some embodiments, a method may include configuring, by a user equipment, at least a first transmission configuration index (TCI), a second TCI, and at least two non-overlapping frequency resource regions in a single time domain resource. The first TCI may be associated with at least one non-overlapped frequency resource region. The second TCI may be associated with at least one non-overlapped frequency resource region which not assigned to the first TCI. At least one association of a state of the first TCI, a state of the second TCI, and the at least one non-overlapping resource region may be changed in a next time domain repetition instance.

Abstract: Various communication systems may benefit from suitable coding schemes. For example, certain wireless communication systems may benefit from using low density parity check and other reliability mechanisms A method can include communicating at least one transport block for ultra-reliable low-latency communications between a sending device and a receiving device. The transport block can be coded using a base graph according to one of the following three options: using only low density parity check base graph #2; using only low density parity check base graph #2 and truncated low density parity check base graph #1; or using low density parity check base graph #2, truncated low density parity check base graph #1, and low density parity check base graph #3.
