    Abstract: There are provided measures for enabling/realizing higher-layer beam management, e.g. beam failure detection or beam candidate detection in a higher layer such as a MAC entity. Such measures exemplarily comprise that a beam management timer is started when a (first) beam management instance indication from a lower layer is obtained, beam management is executed, wherein a beam management instance counter is incremented whenever a beam management instance indication from the lower layer is obtained and a beam management event is detected when the beam management instance counter reaches a beam management instance threshold before expiry of the beam management timer, and the beam management instance counter is reset upon expiry of the beam management timer.

    Abstract: An method includes determining to perform inter-cell multi-downlink control information (multi-DCI) based multi-transmission reception point (multi-TRP) operation for a user device based on the following: receiving, by the user device from a network node, transmission configuration index (TCI) states for a plurality of control resource sets (CORESETS), wherein the TCI states for the plurality of CORESETs are associated with a plurality of cells having different physical cell identities (PCIs) or associated with a plurality of cell groups; and determining, by the user device, that at least one of the following conditions is present: 1) a multi-DCI based multi-TRP-related high layer parameter has been configured to the user device; 2) a default mode of multi-TRP operation has been configured to the user device; or 3) the user device has received control information indicating physical downlink shared channel (PDSCH) TCI state activations corresponding to two different CORESETPoolIndex values; and, performing inter-cell multi-DCI based multi-TRP operation.

    Abstract: In example an embodiment, according to the method, a timer is started to monitor selection of a RA resource in response to a RA procedure for accessing a network device being initiated. The timer is configured with expiration time. The timer is stopped in response to a RA resource being selected for transmitting a RA preamble to the network device. A preamble transmission counter is incremented in response to the timer expiring. The preamble transmission counter records the number of transmitted RA preambles. A failure of the RA procedure is indicated in response to the incremented preamble transmission counter exceeding a threshold. The embodiment enables completion of the RA procedure regardless of an out of coverage situation where no beam is available to be selected for transmitting a RA preamble.

    Abstract: According to a first embodiment, a method may include receiving, by a user equipment, at least one indication of at least one non-default measurement profile. The method may further include determining, by the user equipment, that at least one predefined condition applies. The method may further include applying, by the user equipment, one or more of at least one adapted measurement, at least one non-adapted measurement, at least one default measurement profile, at least one non-default measurement profile, at least one adapted measurement profile, and at least one non-adapted measurement profile.

    Abstract: Determination of characteristics of a communication environment may be beneficial in many communication systems. For example, certain wireless communication systems, such as fifth generation (5G) communication systems, may benefit from appropriate mobility measurements. A method can include performing, at a user equipment, beam-specific measurements of a plurality of beams of at least one cell. The method can also include calculating a cell quality based on the beam-specific measurements.

    Abstract: A method including monitoring, by a user equipment (UE) operating in a multi-beam based communication session, signal qualities for a plurality of beams in the multi-beam based communication session (300); determining a beam link failure (BLF) occurring for at least one of the beams in the multi-beam based communication session (302); determining a type of the beam in which the beam link failure (BLF) is occurring (304); and updating a radio link failure (RLF) related condition in dependence on the type of the beam in which the beam link failure (BLF) is occurring (306).
