Abstract: Embodiments of the present disclosure relate to reporting beam failure. A terminal device detects a beam failure on one or more serving cells of the terminal device. If the beam failure is detected on the one or more serving cells, the terminal device obtains information concerning one or more candidate beams and the one or more serving cells. Each of the one or more candidate beams is associated with a respective one of the one or more serving cells. The terminal device then transmits at least a portion of the information to a network device associated with the one or more serving cells.

Abstract: Example embodiments of the present disclosure relate to initiation of small data transmission (SDT). A first device determines whether SDT is allowed to be initiated at a first protocol layer of the first device. In accordance with a determination that the SDT is allowed to be initiated at the first protocol layer, the first device determines whether the SDT is allowed to be initiated at a second protocol layer of the first device. In accordance with a determination that the SDT is allowed to be initiated at the second protocol layer, the first device initiates, via the first protocol layer, a communication procedure for the SDT with a second device. Through this solution, it is possible to avoid unnecessary interactions between protocol layers as well as avoid false resume of the radio bearer when the SDT procedure cannot be performed.

Abstract: Example embodiments of the present disclosure relate to transmission in a small data transmission mode. A first device selects, based on a mode selection configuration, a small data transmission mode to be initiated from a plurality of small data transmission modes. The second device determines selection of a small data transmission mode to be initiated by a first device from a plurality of small data transmission modes. The first device performs a small data transmission procedure with the second device according to the selected small data transmission mode. Through this solution, a suitable SDT mode is selected based on the predetermined or predefined mode selection configuration.

Abstract: Disclosed are devices supporting an enhanced paging procedure for random access or small data transmission. An example UE may include at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured to, with the at least one processor, cause the UE to receive a paging message from a network device and transmit a signal to the network device using an UL grant. The paging message may include an identity of the UE (UE ID) and the UL grant. The related methods, apparatuses and computer program products are also disclosed.

Abstract: Methods and apparatuses for PHR for a serving cell, wherein an active BWP of the serving cell is a dormant BWP. A UE sends a PHR to at least a network node to report PH of the serving cell; the network node receives the PHR from the UE to report PH of the serving cell and obtains PH value from the PHR for the serving cell. Herein at least one of the following is reported for the serving cell: 1) Type 1 PH; 2) Type 3 PH; 3) a designated field indicating whether the PH is Type 1 or Type 3; 4) a designated field indicating whether the serving cell is on a dormant BWP or non-dormant BWP.

Abstract: Embodiments of the present disclosure relate to beam reporting triggered by data transmission. A first device receives from a second device configuration information concerning at least one candidate beam for serving the first device. The first device determines whether data is available for transmission from the first device to the second device. If the data is available for transmission, the first device selects at least one first reference signal identifying the at least one candidate beam based on the configuration information. The first device transmits information concerning the selected at least one first reference signal to the second device.

Abstract: Embodiments of the present disclosure relate to reporting preconfigured up-link 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: Embodiments of the present disclosure relate to dynamic active time trigger in CFRA. A first device receives a random access request from a second device in a discontinuous reception mode. The first device transmits a random access response to the second device. The random access response comprises at least one of: an indicator of an offset between a reception of the random access response and a start of monitoring scheduling information from the first device, or a flag indicating whether the indicator is present in the random access response. The first device transmits the scheduling information to the second device based on the offset.
