Example embodiments of the present disclosure relate to a device, method, apparatus and computer readable storage medium of scheduling request (SR) and random access (RA) triggering for small data transmission (SDT). In example embodiments, a terminal device receives, from a network device, a configuration of one or more configured grant (CG) resources for a SDT procedure and a list of one or more data radio bearers (DRBs) associated with respective logical channels (LCHs) allowed for SDT over at least one of the one or more CG resources. After the terminal device initiates the SDT procedure in an inactive mode, if the terminal determines that a buffer status report (BSR) is triggered, the terminal device determines whether a configuration of a SR mask is to be applied for a LCH configured for SDT.

Scheduling request and random access triggering for SDTN

Example embodiments of the present disclosure relate to an apparatus, method and computer readable storage medium for determining active time with a plurality of discontinuous reception (DRX) groups. In example embodiments, if first transmission is initiated from a device, at least a first DRX group is selected from a plurality of DRX groups. The plurality of DRX groups is configured for the device and associated with a plurality of DRX configurations. The apparatus is further caused to determine first active time for the first DRX group based on a first DRX configuration of the plurality of DRX configurations associated with the first DRX group. Further, the device is allowed to monitor second transmission to the device in the first active time.

Determination of active time with discontinuous reception groups

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.

Data transmission with security configurations

Example embodiments of the present disclosure relate to transmit power control for beam management. The first device transmits a first configuration to a second device. The first configuration indicates information about at least one candidate beam assigned to the second device. Alternatively, or in addition, the first configuration further indicates a correspondence between the at least one candidate beam and a plurality of transmission occasions, where the plurality of transmission occasions are allocated by the first device for transmission from the second device to the first device while the second device is in an inactive mode. The first device detects transmissions from the second device according to the first configuration at the plurality of transmission occasions. Through this solution, a beam management solution and efficient resource configuration for a device in an inactive mode is proposed.

Beam management for a device in an inactive mode

Inter-alia, a method is disclosed comprising: receiving a paging information from a mobile communication network; based on the received paging information, determining whether at least one pre-configured resource of a mobile communication network is to be utilized for responding to the paging information; and based on the determining, initiating at least one transmission via at least one of a random access procedure or on the at least one pre-configured resource. It is further disclosed an according apparatus, a computer program and a system.

Paging response on pre-configured resources

Example embodiments of the present disclosure relate to apparatus, method and computer readable storage media of scheduling request management. The method includes in accordance with a determination that data on a logical channel is available for transmission, determining, at an apparatus, whether there is pending data available for transmission on one or more further logical channels; and in accordance with a determination that there is pending data available for transmission, determining a set of target scheduling request, SR, configurations available for a SR procedure from a plurality of candidate SR configurations associated with the logical channel and the one or more further logical channels; and performing the SR procedure based on the target SR configuration. In this way, the waste of the SR configurations can be avoided and the SR may be transmitted using the fastest SR opportunity.

Scheduling request management

Embodiments of the present disclosure disclose devices, methods and apparatuses for small data transmission (SDT). A terminal device receives, from a network device, an indication message indicating the terminal device to initiate a mobile terminated SDT (MT-SDT). Moreover, the terminal device indicates an access reason of a connection attempt to the network device based on an operation status of the connection attempt.

Devices, methods and apparatuses for data transmission

Embodiments of the present disclosure relate to methods, devices, apparatuses, and computer readable medium for small data transmission (SDT). A first device, in response to first data to be transmitted via a SDT corresponding to a first set of resources for a random access procedure and a second set of resources for a configured grant procedure, determine a target resource for at least a part of the first data based on a logical channel restriction on the SDT; and transmit, to a second device, at least the part of the first data on the target resource. In this way, the SDT procedure can be performed with logical channel restrictions, which allows a better isolation of services through specific resource selection. The communication efficiency and network performance can also be improved.

A method is provided where handover information about one or more target beams of a target cell is provided. The beam quality of those target beams is determined along with beam quality of one or more other beams of the target cell. Dedicated uplink resources associated with the target beams and shared uplink resources are associated with the other beams. It is determined based on the beam quality which of the target and other beams is to be used to initiate a connection to the target cell.
