Abstract: Example embodiments of the present disclosure relate to grant skipping for a small data transmission (SDT) procedure. A first device determines whether data is available for transmission on a grant, the grant being allocated for a SDT procedure established between the first device and a second device. In accordance with a determination that the data is unavailable, the first device determines whether the transmission on the grant is to be skipped. In accordance with a determination that the transmission on the grant is not to be skipped, the first device performs the transmission on the grant to the second device, the transmission conveying a predetermined type of information without conveying the data. Through this solution, the SDT procedure between the devices can be maintained as long as possible, to allow the first device to transmit subsequent data to or receive subsequent data from the second device without initiating a new SDT procedure.

Abstract: Example embodiments of the present disclosure relate to bandwidth part selections of random access procedure. According to embodiments of the present disclosure, a terminal device receives configuration information from a network device. The configuration information indicates a set of BWPs and configurations of the set of BWPs.

If the condition is fulfilled, the terminal device switches to the target BWP. In this way, it improves resource efficiency.

Abstract: Example embodiments of the present disclosure relate to resource selections of random access procedure. According to embodiments of the present disclosure, when a random access procedure is triggered for a certain feature combination, the terminal device determines the random access channel (RACH) partition to use based on a defined priority order of (RACH-partition) features whenever a RACH partition that would have matched the feature combination for which the RA procedure is triggered is not provided in the cell. The priority order could be pre-defined in the standards, provided by the Mobile Network Operators (MNO), or signaled dynamically by the network via system information or dedicated signaling (e.g., radio resource control (RRC) or medium access control (MAC) signaling). In this way, better resource selections may be achieved. Moreover, it does not need to configure resources for any possible combinations of features.

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 communication for SDT. A first device transmits a resume request for SDT to a second device. The second device transmits, to the first device, a message for rejecting the resume request for a part of data transmissions, said part including SDT. In this way, a resume procedure for non-SDT may still be possible. Further, not congested resources for SDT or non-SDT may be used even in case of RRC reject procedure. In addition, services may be not delayed.

A first device receives, from a second device, configuration information indicating first resources for the first device to perform a random access to a secondary cell of the first device. Radio network temporary identifiers corresponding to the first resources are different from radio network temporary identifiers corresponding to second resources configured for a random access to a primary cell of the first device. The first device selects a resource from the first resources and transmits, to the second device via the secondary cell, a random access request by using the selected resource.
