This disclosure provides methods, devices, and systems for physical uplink shared channel (PUSCH) repetition based on support signaling, such as an uplink grant that includes a time domain resource assignment for transmitting one or more data repetitions that may cross a slot boundary. The UE may identify directions (for example, uplink, downlink, flexible) for one or more symbols spanning a transmission duration of the time domain resource assignment. The directions may be determined using a dynamic slot format indication (SFI), or semi-static SFIs may be used as a fallback (when dynamic slot format indications do not meet a target reliability). The uplink grant may include an indication of which symbol directions can be used for the one or more data repetitions. A subset of the one or more symbols for scheduling the one or more data repetitions may be determined based on the identified directions.

The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may receive an indication of at least one TDRA table for one of a plurality of TB modes for communication with the base station, the plurality of TB modes including at least one of a first TB mode or a second TB mode, the first TB mode corresponding to multiple TBs via a single grant, the second TB mode corresponding to a single TB with at least one repetition via the single grant. The apparatus may also apply, based on the at least one TDRA table, the one of the plurality of TB modes for the communication with the base station. Additionally, the apparatus may transmit uplink data, or receive downlink data, based on the one of the plurality of TB modes.

A user equipment (UE) may be configured with one or more queues at which packets are accumulated before being transferred between at least one higher layer and at least one lower layer. The UE may release packets from the one or more queues based on at least one set of parameters. The UE may determine one or more radio conditions associated with at least one traffic flow between the UE and a network. The UE may configure a set of parameters associated with transfer of packets for the at least one traffic flow between a lower layer of the UE and a higher layer of the UE based on the one or more radio conditions. The UE may communicate a first set of packets with the network for the at least one traffic flow based on the set of parameters.

A method for handling data, dangling in a new radio (NR) leg of a split bearer, by a user equipment (UE) is disclosed. The method comprises predicting occurrence of NR uplink (UL) leg switch; sending a buffer status report (BSR) pertaining to protocol data units (PDUs) in radio link control (RLC) layer and media access control (MAC) layer in the NR leg based on predicting the occurrence of NR UL leg switch; and initiating recovery of dangling PDUs in the NR leg after the occurrence of the NR UL leg switch, wherein the recovery includes sending the dangling PDUs to a long term evolution (LTE) leg of the split bearer.

A timing control method, performed by a first DU including a processor and a modem in a base station supporting function-splitting, includes obtaining, by the processor, first time information from a CU included in the base station; obtaining, by the processor, synchronization information with a first system based on the first time information; identifying, by the processor, a change time point of an SFN based on the synchronization information; generating, by the processor, a first timing control signal including a signal indicating a changed SFN and a first tick signal having a same periodicity as a change periodicity of the SFN when the SFN is changed; and providing, by the processor, the first timing control signal to the modem.
