Abstract: This disclosure relates to techniques for scheduling radio resource control connections between a wireless device and a network element of a network in advance. According to some embodiments, a wireless device may provide an indication of one or more types of upcoming data traffic to the network element. The network element may schedule one or more radio resource control connections for the wireless device based at least in part on the indication of one or more types of upcoming data traffic. The network element may provide an indication of the scheduled radio resource control connection(s) to the wireless device. The wireless device and the network may establish the scheduled radio resource control connection at the scheduled time.

Abstract: A method for initiating a codec rate change during a VoIP call by a wireless communication device is disclosed. The method can include the wireless communication device establishing a first codec rate for use in the VoIP call during a call establishment phase; using the first codec rate to encode voice data for transmission during a first portion of the VoIP call; determining a channel quality while using the first codec rate; determining that the channel quality satisfies a threshold for requesting a codec rate change; requesting a codec rate change from the first codec rate to a second codec rate in response to the channel quality satisfying the threshold; and using the second codec rate to encode voice data for transmission during a second portion of the VoIP call.

Abstract: A method for triggering cell transition in an uplink power limited condition is disclosed. The method can include a wireless communication device determining that the wireless communication device is experiencing an uplink power limited condition; deriving a modified downlink channel quality measurement by adjusting a measured downlink channel quality to indicate a lower downlink channel quality than the measured downlink channel quality; generating a measurement report including the modified downlink channel quality measurement; and sending the measurement report to the serving cell to trigger transition of the wireless communication device from the serving cell to a second cell.

Abstract: A user equipment (UE) may operate on a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier. The UE identifies a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier corresponding to a primary secondary cell (PSCell) of a secondary cell group (SCG) for dual connectivity (DC), receives an indication that an active BWP is to be switched from the non-dormant BWP to the dormant BWP and performs an action corresponding to the dormant BWP.

Abstract: A user equipment (UE), next generation NodeB (gNB), or other network component can operate to configure a group configuration message that initiates a plurality of UEs in a coverage area of a non-terrestrial network (NTN) to concurrently transfer communication from a first beam of a first satellite to a second beam of a second satellite. The communications of one or more UEs can be re-directed to the second beam of the second satellite based on downlink control information of the group configuration message.
