Various solutions for capability reporting to support small data transmission (SDT) on a bandwidth part (BWP) for user equipment (UE) are described. An apparatus may transmit UE capability information to a wireless node of a wireless network. The UE capability information may indicate that the apparatus supports using a BWP with a condition of synchronization signal block (SSB) association for SDT. The apparatus may also receive a configuration associated with the BWP for SDT from the wireless node. The configuration may be configured based on the UE capability information. The apparatus may further initiate an SDT procedure on the BWP according to the configuration.

Systems and methods described herein provide optimized resource management to meet Ultra-Reliable Low-Latency Communications (URLLC) service requirements in Radio Access Networks (RANs), such as Fifth Generation New Radio (5G-NR) RANs. A network device stores resource management policy options for implementing communication sessions for a URLLC service level and determines that the URLLC service level is required for a communication session requested by a user equipment (UE) device. The network device selects one of the resource management policy options for the communication session based on a number of antennas used by an access station supporting the communication session and one of: an estimated available bandwidth for the access station or a transmission delay for processing a packet in the communication session. The network device sends, to the access station, the selected one of the different resource management policy options.

A system of managing communications in a vehicle includes a telematics unit connected to the vehicle. The telematics unit is configured to execute a retransmission request protocol upon receipt of erroneous data. A command unit in communication with the telematics unit, the command unit having a processor and tangible, non-transitory memory on which instructions are recorded. The command unit is adapted to determine vehicle situational parameters at a beginning of a data communication cycle. The vehicle situational parameters including current location and navigation status of the vehicle. When a first retransmission according to the retransmission request protocol is detected, the vehicle situational parameters are updated. The command unit is adapted to determine a desirable value of a retransmission frequency for the retransmission request protocol based in part on the updated vehicle situational parameters. In one embodiment, the retransmission request protocol is Hybrid Automatic Repeat Request (HARQ).
