    Abstract: According to a first embodiment, an apparatus may include at least one processor and at least one memory including computer program code. The at least one memory and the computer program code can be configured to, with the at least one processor, cause the apparatus to at least determine at least one reference value configured to evaluate at least one beam change condition based on at least one measurement. The at least one memory and the computer program code can be further configured to, with the at least one processor, cause the apparatus to at least determine whether at least one beam has changed. The at least one memory and the computer program code can be further configured to, with the at least one processor, cause the apparatus to at least, upon determining that the at least one timer T has expired, determine that the at least one beam change condition has been fulfilled.

    Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable mediums for beam failure recovery. The method includes detecting a beam failure on a serving cell of the terminal device, the serving cell including at least one of a primary cell and a secondary cell serving the terminal device. The method further includes in response to detecting the beam failure on the serving cell, generating a medium access control, MAC, control element, CE, the MAC CE including a field associated with the serving cell, wherein the field is set to be a predefined value indicating the beam failure. The method further includes transmitting the MAC CE to a network device associated with the serving cell.

    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: Various communication systems may benefit from the appropriate handling of transitioning between connections. For example, certain wireless communication systems may benefit from appropriate handling of further access attempts in a conditional handover scenario. A method can include receiving, at a user equipment, an access configuration information element configured to describe a user equipment behavior during an access phase of a conditional handover. The method can also include, upon detecting a failed access to the target for which the access condition has triggered, attempting to access a candidate cell among suitable candidate cells that have been previously configured for conditional handover.
