Abstract: Embodiments of the present disclosure relate to random access in a communication system. A first device determines whether a contention-free random access resource is allocated from a second device for a first random access type. In accordance with a determination that the contention-free random access resource is allocated, the first device compares a target transport block size corresponding to the contention-free random access resource with a first transport block size configured for a first group of preambles available for the first random access type and performs random access to the second device based on a result of the comparison.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of TRP beam failure recovery. The method comprises determining a set of failed cells associated with the first device based on a beam failure detection; and generating a beam failure report indicating respective one or more failure detection resource sets associated with at least a portion of the set of failed cells. In this way, the UE may determine the information included in the BFR MAC CE in a case where the UL grant is not enough to include all the information for the failed serving cells or the BFR MAC to be transmitted on the MSG3 or MSGA in a CBRA procedure on the SpCell.

Abstract: Embodiments of the present disclosure relate to methods, devices, apparatuses, and computer readable medium for adaptive backoff for random access channel (RACH). The method comprises: transmitting, at a first device and to a second device, a first message for requesting a first random access to a cell of the second device, resources of the cell being partitioned into a plurality of partitions for a plurality of features, and the first random access associated with a first partition for at least a first feature of the plurality of features; and receiving, from the second device, a second message comprising backoff information corresponding to one of the first feature and the first partition. Since the network is capable of providing backoff applicability information per features or per RACH partitions, the UE using a congested RACH partition can apply backoff in the RA procedure, while accessing of legacy UE or a UE using a RACH partition without congestion would not be affected.

Abstract: Various example embodiments relate to methods and apparatus that support beam management in a small data transmission procedure. A terminal device may comprise at least one processor and at least one memory. The at least one memory includes computer program code stored thereon. The at least one memory and the computer program code may be configured to, with the at least one processor, cause the terminal device to report one or more available beams in a small data transmission procedure, receive a beam switching command to switch a serving beam for the small data transmission procedure, and switch the serving beam for the small data transmission procedure to a target beam indicated in the beam switching command.

Abstract: Example embodiments of the present disclosure relate to logical channel prioritization. A method includes obtaining an uplink grant from a network device, the uplink grant indicating uplink resources for transmission to the network device and selecting a logical channel prioritization setting from a plurality of logical channel prioritization settings based on a predetermined policy related to the uplink grant, the logical channel prioritization settings defining different sets of prioritization parameters for uplink data in at least one logical channel and uplink control information in occupying the uplink resources. The method further includes generating, based on the logical channel prioritization setting, a packet data unit including at least one of the uplink control information or at least one part of the uplink data for transmission to the network device using the uplink resources. In this way, adaptive and dynamic prioritization across logical channels can be achieved at the terminal device.

Abstract: Embodiments of the present disclosure relates to beam failure detection. According to embodiments of the present disclosure, after a serving cell is activated from a deactivated state, a terminal device monitors a beam failure on a serving beam of the serving cell. If a beam failure instance indication is received within a short period after the activation, the terminal device determines that the beam failure is detected on the serving beam. In this way, a beam failure recovery can be quicker triggered to perform candidate beam search.

Abstract: This disclosure presents apparatuses and methods to determine, assign, and communicate paging subgroups using assistance information. In some aspects, assistance information can include user equipment (UE) parameters, for example, UE capability parameters, UE type parameters, ID preference parameters, location parameters, or mobility parameters. In some aspects, assistance information can include network parameters, cell parameters, or information about a subset or all UEs registered on the network. The radio access network (RAN) or core network (CN) can utilize the assistance information to determine the number of paging subgroups and to assign one or more subsets of UEs to each paging subgroup. The RAN or CN can communicate the paging subgroups to one or more of the UEs within the network. In some aspects, the paging subgroup can be directly indicated to the UE. In some aspects, the paging subgroup can be derived by the UE using the received paging subgroup information.

Abstract: According to embodiments of the present disclosure, when an unknown secondary cell configured with a physical uplink control channel is activated, a terminal device determines whether to transmit beam information to a network. The terminal device receives a physical downlink control channel (PDCCH) order in a beam which is selected in association with the beam information. In this way, a proper beam can be determined to transmit PDCCH order and it can also reduce delay.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of data transmission with security parameters. The method comprises: receiving, from a second device, a first plurality of parameters associated with a connection resume procedure between the first device and the second device; in accordance with a determination that the connection resume procedure is to be performed, transmitting, in the inactive state and to the second device, a request for connection resume, the request comprising one or more of the first plurality of parameters; and performing the connection resume procedure with the second device. In this way, the terminal device is capable of triggering non-SDT procedure when the SDT procedure is ongoing.
