    Abstract: Embodiments of the present disclosure relate to mechanism for first random access mode falling back to second random access mode. According to embodiments of the present disclosure, the fallback to second random access mode is indicated in messageB and the user equipment only needs to monitor the messageB for the quick mode on the downlink control signal which is addressed to an identifier. The user equipment does not need to monitor the downlink control channel for the second random access mode. In this way, the user equipment is allowed to fall back to the second random access mode without further retry of the quick mode, thereby reducing overload and latency.

    Abstract: In one exemplary embodiment, a method includes: determining, by a network node, information of at least one period of time that a user equipment is to monitor for a wake-up signal to decode, where the information comprises indications of a configuration or a behavior for the user equipment to dynamically control the monitoring of the wake-up signal for the decoding; and communicating signaling comprising the information towards the user equipment. In another exemplary embodiment, a method includes: receiving from a network node, by a user equipment, information of at least one period of time that the user equipment is to monitor for a wake-up signal to decode, where the information comprises indications of a configuration or a behavior for the user equipment to dynamically control the monitoring of the wake-up signal for the decoding; and using the information to perform the monitoring of the wake-up signal for the decoding.

    Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable mediums for random access procedure. The method comprises transmitting, at a terminal device, a random access request in a random access procedure to a network device; in response to receiving, in the random access procedure, from the network device an uplink grant for the terminal device, determining whether a first size of a first data unit indicated by the uplink grant matches a second size of a second data unit stored in a buffer of the terminal device; in response to determining that the first size mismatches the second size, determining a first part of the second data unit for subsequent transmissions.

    Abstract: A method includes determining whether a downlink beam signal is being received from a base station (502); when the downlink beam signal is being received from the base station, determining whether a measurable property of the downlink beam signal does not meet a preselected threshold (504); when the downlink beam signal is not being received from the base station or when the measurable property of the downlink beam signal does not meet the preselected threshold, transmitting a message to the base station indicating that at least one uplink beam corresponding to the downlink beam has failed (506); and receiving a reply message from the base station with information required to determine a new uplink beam (508). An alternative method includes determining whether at least one uplink beam signal is being received from a user equipment (602); determining whether a measurable property of the at least one uplink beam signal does not meet a preselected threshold, when the at least one uplink beam signal is being received from the user equipment (604); and transmitting a message to the user equipment to initiate uplink beam recovery, when at least one uplink beam signal is not being received from the user equipment or when the measurable property of the at least one uplink beam signal does not meet the preselected threshold (606).

    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.
