    Abstract: An approach to provide dynamic adjustment in order to meet the limitation of data rate per network slice in the uplink and downlink wireless connections in a wireless network. The approach uses a network slice quota (NSQ) management function, which keeps track of aggregated maximum bit rates (AMBR) for a slice. Upon reaching a limit, the NSQ functionality dynamically adjusts the user equipment (UE) data rates, reduces the quality of service (QoS), and/or rejects any protocol data unit (PDU) request. Several techniques are described that meet these objectives. In one technique, when the limit is reached, the session AMBR per subscription level is adjusted in proportionate ratio of the maximum bit rate per subscription level per UE. In another technique, when the limit is reached, there is a proportionate equivalent increment and decrement of session AMBR based on usage patterns of the subscription levels. In a further technique, when the limit is reached, there is a proportionate equivalent increment and decrement of slice resources based on usage patterns. In yet another technique, a quota update is attempted using the Unified Data Repository (UDR).

    Abstract: A device, system, and method estimate a link budget on a companion device. The method is performed at a first device connecting to a second device over a first connection and a network over a second connection, the second device connecting to the network over a third connection. The method includes receiving initiating data from the second device based on radio conditions associated with the third connection. The method includes, when the first device disconnects from the second device and establishes the second connection, determining an initial network metric value based on the initiating data that is used to estimate radio conditions associated with the second connection. The method includes selecting a data exchange mode of the first device based on the initial network metric value which is used until a further network metric is determined by the first device.

    Abstract: Techniques for multi-universal subscriber identity module (MUSIM) operation include generating, by a terminal equipment (TE) of a device, an attention (AT) command. The AT command indicates a value of a parameter related to MUSIM operation of the device, such as whether to release a Non-Access Stratum (NAS) connection associated with a particular USIM of the device, whether to reject or restrict paging associated with the particular USIM of the device, or a requested (or selected) IMSI offset associated with the particular USIM of the device. The AT command is communicated from the TE to a mobile terminal (MT) of the device through a terminal adapter (TA).
