Abstract: A user equipment (UE) may receive, from a network entity, a configuration of one or more candidate cells for switching to from a serving cell. The UE may receive, from the network entity, an indication to deactivate all transmission configuration indicator (TCI) states associated with one or more indicated cells. The UE may deactivate the all TCI states associated with the one or more indicated cells based at least in part on receiving the indication to deactivate the all TCI states. One or more of the one or more candidate cells or the serving cell may include the one or more indicated cells.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of CG resource handling for SDT. The method comprises receiving, from a second device, information indicative of availability of one or more candidate beams for a subsequent transmission after an initial transmission of a small data transmission procedure; and determining, based on the information, a set of target resources the subsequent transmission. With the solution of the present disclosure, the network may not need to monitor all the beams configured to the UE after the successful reception of the initial CG-SDT transmission, which may simplify the implements of the network and therefore improve the system performance. Meanwhile, the resources configured for multiple beams, which has been released or suspended by a UE, can be used for other UEs to increase resource efficiency given that likely the initial serving beam may remain the strongest throughout the entire SDT procedure.

Abstract: An apparatus receives, from a base station, configuration information configuring two or more beam failure detection reference signal sets for one or more serving cells. At least one of the one or more serving cells is configured with multiple beam failure detection reference signal sets comprising at least a first beam failure detection reference signal set and a second beam failure detection reference signal set. The apparatus may monitor and encode, when the beam failure is detected for the first beam failure detection reference signal set and the second beam failure detection reference signal set, into at least two bitmaps in a medium access control control element, MAC CE, failure status information of the first beam failure detection reference signal set and failure status information of the second beam failure detection reference signal set; and transmit the MAC CE comprising the failure status information.

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: Systems, methods, apparatuses, and computer program products for early measurement reporting during small data transmission. A method may include receiving, from a network element, an early measurement reporting configuration. The method may also include receiving, from the network element, an indication of whether early measurement reporting during small data transmission is allowed. The method may further include initiating small data transmission to the network element. In addition, the small data transmission may include an early measurement reporting report when early measurement is allowed.

Abstract: Lower layer triggered mobility LTM for a user equipment moving through a communication network with multiple network nodes supporting radio coverage in multiple cells is considered. The user equipment receives a message from a network node indicating a plurality of lower layer mobility candidate cells and in response attempts a switch to a target cell selected from one of the plurality of candidate cells. Where the attempt fails the user equipment attempts completion of a switch to a further target cell selected from the plurality of candidate cells.

Abstract: According to an aspect, there is provided a terminal device for performing the following. The terminal device obtains, when the terminal device is in an inactive state while a small data transmission, SDT, procedure is ongoing, information that indicates transmission of a data unit over a radio bearer to the terminal device. The terminal device checks whether or not the radio bearer is configured for the SDT procedure. The terminal device determines whether or not to avoid further processing and/or decoding of the data unit based at least on the checking.

Abstract: Mechanism on configured grant transmissions is provided. If a small data transmission is needed, a first device determines whether a timing advance is valid in a subsequent CG occasion for the small data transmission. The first device also determines whether an evaluation of a validity condition is applicable in the subsequent CG occasion for the small data transmission. If the timing advance is valid and the evaluation is applicable, the first device performs the small data transmission in the subsequent CG occasion. In this way, the first device is able to perform the evaluation of the validity condition in advance, thereby reducing delays and avoiding failures.
