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: Systems, methods, apparatuses, and computer program products for user equipment are provided. A method may include determining to transmit, upon data arrival on a logical channel, the data on a configured grant for the logical channel. The method may also include transmitting, based on the determination, the data on the configured grant to activate a cell. In an example embodiment, the transmission on the configured grant may be performed regardless of a current activation status of the cell for which the configured grant is configured, or a suspend status of the configured grant.

Abstract: Various communication systems may benefit from the appropriate handling of scheduling requests. For example, certain wireless communication systems may benefit from a scheduling request procedure involving multiple scheduling request configurations. A method can include transmitting, by a device, a first scheduling request at a first time. The method can also include setting, by the device, a timer from the first time prohibiting subsequent scheduling requests for a predetermined duration based on the transmission of the first scheduling request. The method can further include Identifying, by the device, a trigger for a new scheduling request subsequent to the first scheduling request. The method can additionally include modifying the timer based on the new scheduling request.

Abstract: Example embodiments of the present disclosure relate to a solution for determining a contention resolution timer. In an aspect, a first device receives, from a second device, an indication to perform Msg3 transmission. The first device transmits, to the second device, information of the first device for contention resolution. In case a configuration of a 4-step random access channel is unavailable in an active bandwidth part for the first device, the first device determines a duration for monitoring a contention resolution message based on one of: a first configuration of a 2-step random access channel in the active bandwidth part, or a second configuration of a 4-step random access channel in a bandwidth part different from the active bandwidth part. Example embodiments of the present disclosure can improve the performance of a random access procedure.

Abstract: Various communication systems may benefit from the appropriate control of the timing of communication. For example, certain wireless communication systems may benefit from packet data convergence protocol windows, for example in the case of split bearers being in use. A method can include transmitting a plurality of protocol data units over a bearer mapped to a plurality of logical channels. The protocol data units can be transmitted in a radio link control unacknowledged mode. The method can also include managing at least one transmission characteristic of the transmitted plurality of protocol data units.

Abstract: There is disclosed an apparatus. The apparatus comprises means for using a first random access type in a random access procedure; and in response to determining that a threshold number of failed random access attempts has been reached using the first random access type, determining whether to switch to using a second random access type which is different from the first random access type.

Abstract: A method is provided including determining a mapping of a scheduling request to one or more logical channels configured for a user equipment; in response to a received scheduling request, allocating an uplink radio resource such that a transmission time interval of the allocated uplink radio resource has a length corresponding to length of a transmission time interval configured for the mapped one or more logical channels; and receiving data on the allocated uplink radio resource. A further method includes transmitting a scheduling request mapped to one or more logical channels configured for a user equipment; receiving an allocation of an uplink radio resource wherein a transmission time interval of the allocated uplink radio resource has a length corresponding to length of a transmission time interval configured for the mapped one or more logical channels; and sending data on the allocated uplink radio resource.
