Abstract: This disclosure provides systems, methods, apparatuses and computer-readable medium for wireless communication. In some aspects, a user equipment (UE) may receive, from a first base station (BS) associated with a fifth generation New Radio (5G NR) radio access technology (RAT), a command of mobility from the 5G NR RAT to a second RAT. The UE may determine that the command of mobility is for voice fallback. The UE may transmit, to a second BS associated with the second RAT and based at least in part on determining that the command of mobility is for voice fallback, a radio resource control (RRC) connection request communication for attempting to communicatively connect with the second BS for voice fallback.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. Further, the apparatus may be configured to determine that content is available for reception based on broadcast context information. In an aspect, the apparatus may be in an idle or inactive mode and may be associated with a first base station that is associated with a first radio access technology (RAT) that does not support broadcasting of the content. The apparatus may be further configured to receive a release message from the first base station, the release message including redirection information indicating a second base station associated with a second RAT that supports broadcasting of the content, establish a connection with the second base station based on the redirection information, and receive the content from the second base station using the second RAT.

Abstract: Various aspects of the disclosure relate to handover of a user equipment (UE) between a standalone mode of operation and a non-standalone mode of operation. For example, a UE may be handed-over from standalone to non-standalone, or vice versa. Moreover, this handover may be an inter-system handover (e.g., between an LTE core network and an NR core network).

Abstract: Various aspects described herein relate to techniques for operating mode and cell selections and reselections in wireless communications. In an aspect, the method includes determining that a user equipment (UE) is in an idle mode, and receiving, by the UE, system information from one or more candidate cells including at least a Long Term Evolution (LTE) candidate cell or a New Radio (NR) candidate cell. The method further includes selecting or reselecting, by the UE, a cell from the one or more candidate cells to be camped on and an operating mode from an LTE mode, a Standalone (SA) mode, or a Non-standalone (NSA) mode, based on at least the received system information.

Abstract: A user equipment (UE) may be configured to join a group call, which may include mission critical (MC) data. The UE may be configured to receive, through a broadcasted group discovery channel (GDCH), a list of group call services and corresponding session description protocol (SDP) information for establishing the group call services. The UE may be configured to determine at least one group call service of the group call services to receive. The UE may be configured to establish the at least one group call service based at least in part on the corresponding SDP information received through the broadcasted GDCH.

Abstract: In a multi-subscriber identity module (SIM) device for wireless communication, data usage is transferred from one subscription to another subscription. When it is determined the data utilized for a first subscription associated with a first SIM of the multi-SIM device is above a first data allowance threshold, then the data communication associated with the first subscription is transferred to a second subscription associated with a second SIM of the multi-SIM device. The transferring may occur when data utilized for the second subscription is below a second data allowance threshold.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus sends a message including an indication of at least one frequency of interest and at least one alternative frequency of interest. In an aspect, the at least one frequency of interest is used to provide a set of multimedia broadcast multicast service (MBMS) services and the at least one alternative frequency of interest is used to provide a subset of MBMS services of the set of MBMS services. The apparatus receives, for each MBMS service in the set of MBMS services, said each MBMS service using one of the at least one frequency of interest or the at least one alternative frequency of interest based on the message.

Abstract: A base station may allocate served user equipments (UEs) into measurement gap groups, which are configured to reduce the overlap between UE measurement gaps used for inter-RAT measurement. The base station may configure the measurement gap groups based on an offset between subframes of a served and measured RAT and may distribute UEs in the measurement gap groups to avoid overlapping inter-RAT measurement times, thereby reducing idle base station resources.
