Abstract: Example embodiments relate to communication of uplink control information. A method implemented at a terminal device comprises obtaining a plurality of uplink grants available for uplink transmission to a network device, the plurality of uplink grants indicating resources for the uplink transmission; determining prioritization of the plurality of uplink grants in transmission of uplink control information based on a predetermined prioritization policy; and selecting, based on the determined prioritization, an uplink grant from the plurality of uplink grants for transmission of the uplink control information to the network device. In such a way, it is possible to increase a probability of transmission of the uplink control information and/or a probability of improving power efficiency of the terminal device.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of channel access procedure based on the channel access priority class (CAPC). The method comprises receiving scheduling information from a second device, the scheduling information at least indicating resources allocated for a transmission from the first device to the second device, a channel access type for the transmission and an expected access priority for the transmission. The method further comprises comparing the expected access priority with an access priority of data in a buffer of the first device and determining use of the resources based on the comparison. In this way, the Channel Occupancy Time (COT) sharing can be used only for the data with higher or equal priority to avoid unintended usage of the grant on unlicensed band and coexistence fairness among nodes with different types of traffic to be transmitted may be achieved.

Abstract: Systems, methods, apparatuses, and computer program products for random access procedures, for example when operating in unlicensed band, are provided. One method may include starting a retransmission timer when LBT failure is detected at a UE for one or more initial msg3 transmission opportunities. The method may also include determining whether a retransmission grant is received before expiry of the retransmission timer.

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: Disclosed are example embodiments of methods and apparatuses supporting a small data transmission (SDT) procedure to random access (RA) procedure fallback. A method may comprise initiating a small data transmission (SDT) procedure for transmission of uplink data to a network device, determining if a condition is satisfied, and transitioning from the SDT procedure to another procedure for transmission of the uplink data when the condition is satisfied. The another procedure may be a random access (RA) procedure different from the SDT procedure.

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.
