Abstract: Example embodiments of the present disclosure relate to beam failure recovery mechanism. According to embodiments of the present disclosure, there are provided an improved solution for reporting candidate beams in serving cells. If a beam failure occurs in a serving cell, the first device determines a candidate beam for beam failure recovery from a plurality of beams in the serving cell based on link qualities of the plurality of beams. The first device also determines a resource configuration for a random access for the beam failure recovery for the first device or a resource to be used for the random access, The first device further generates an indication for indicating a characteristic of the candidate beam or a characteristic of a beam for performing the random access, based on at least one of the determined resource configuration or the determined resource. The first device also transmits an identity of the candidate beam and the indication to a second device. The second device performs the beam failure recovery based on the candidate beam and the characteristic of the candidate beam.

Abstract: Systems, methods, apparatuses, and computer program products for prioritized random access during handover are provided. One method may include transmitting, by a source network node, a handover request to a target network node. The handover request may include an indication of a recognition of prioritized random access for a user equipment. The method may also include receiving an acknowledgement from the target network node, building a reconfiguration message, for the user equipment, comprising a prioritized set of random access parameters, and transmitting, to the user equipment, the reconfiguration message comprising the prioritized set of random access parameters.

Abstract: Embodiments of the present disclosure relate to for inter-CU topology adaptation. A first device establishes a communication interface between the first device and a second device. The first device receives from the second device a handover complete message indicating that a handover of the second device from a third device to the first device is completed. The first device transmits to the second device a command indicating the second device to activate cells configured by the first device.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of enhancing a report for random access channel (RACH). The method comprises in accordance with a determination that a random access attempt in a random access process for accessing a second device based on configuration information is performed, determining an entry for recording the random access attempt, the entry at least comprising fallback information indicating whether a change associated with the random access attempt has occurred; generating a report for the random access process at least based on the entry; and causing the report to be transmitted to the second device. In this way, with the UE RACH report, the network device may achieve a targeted optimization for the configuration for RA process, which may improve the efficiency of the RA process and decrease the cost due to a multiple of fallback.

Abstract: Embodiments of the present disclosure relate to reporting preconfigured uplink transmission failure. According to embodiments of the present disclosure, the terminal device logs failures associated with transmission on the preconfigured resources and failure causes. The terminal device transmits the logged information to the network device. In this way, the network device is aware of the failure occurrences and their reasons. The network device is able to use the information for configuring uplink resources more efficiently and the resources can be efficiently allocated for other purpose or other terminal devices.

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.
