  • Publication number: 20240313936
    Abstract: Aspects of the subject matter described herein are directed towards indicating to a wireless network device which time-division duplex slot patterns (slot formats) are supported by a user equipment device, e.g., which slot patterns have gone through interoperability and deployment testing (IODT) successfully with respect to the type of user equipment device. With the supported slot pattern information, the network can make an intelligent decision on scheduling downlink/uplink ratios, while selecting a slot pattern that the user equipment device is known to support. In one aspect, the technology adds a “Slot format IODTed” information element in the user equipment device capability information, which the network obtains when the user equipment device reports its capabilities to the network. In another aspect, the network can query the user equipment device for the supported slot format information.

  • Patent number: 12063111
    Abstract: Techniques for controlling parameters for uplink transmission associated with a device to facilitate improving a communication condition metric(s) (CCM(s)) of the uplink transmission are presented. A communication management component (CMC) can determine whether CCM satisfies a first threshold CCM. If CCM does not, CMC can modify a parameter(s) to reduce a number of resource blocks or an MCS value to improve the CCM. If respective minimum threshold levels have been reached for the number of resource blocks and MCS value, and CCM still is not satisfying the first threshold CCM, CMC can modify a parameter to increase an amount of repetition of data packets for uplink transmission (unless a maximum threshold amount of repetition is reached). If CCM satisfies an applicable threshold CCM for a defined amount of time, CMC can modify parameters to increase the number of resource blocks, increase MCS value, or reduce repetition of data packets.

  • Publication number: 20240267839
    Abstract: Automatic neighbor relationships (ANR) can be implemented within a radio access network intelligent controller (RIC), which receives load information from network nodes and user equipment measurements from user equipment. The RIC can create and maintain real-time load information and leverage slicing knowledge of neighbor cells during mobility to direct the user equipment to various network slices. Thus, an enhanced radio access network (RAN) neighbor relationship that utilizes slicing information can provide slice level RAN neighbor visibility on top of physical ANR relationships to enable enhancements for mobility management optimization.
