Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. The UE may identify a first set of bands associated with a first subscription and a second set of bands associated with a second subscription. The UE may determine that at least a first band from the first set of bands and at least a second band from the second set of bands share a same set of radio frequency (RF) front-end resources. The UE may then refrain from communicating on a third band from the first set of bands while communicating on a remaining set of bands, where the third band may be associated with a secondary component carrier (SCC) of a multi-carrier communications scheme. Refraining from communicating on the third band may be based on the first and second bands sharing the RF front-end resources and the third band being associated with the SCC.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate via a first connection using one or more transmit parameters. The UE may determine to suspend subsequent attempts to communicate via a second connection, in a dual connection mode, based at least in part on satisfaction of a threshold number of failed attempts to communicate via the second connection. The UE may determine one or more parameters for suspension of the subsequent attempts to communicate via the second connection based at least in part on a determination that satisfaction of the threshold number of failed attempts is associated with one or more exposure conditions that are based at least in part on the one or more transmit parameters. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for improving call setup performance. In certain aspects, a User Equipment (UE) or a network servicing the UE, may detect at least one of the occurrence or anticipated occurrence of circuit switched (CS) signaling by a user equipment (UE), wherein the CS signaling at least comprises signaling associated with a CS call setup procedure, suspend packet-switched (PS) signaling or processing of such PS signaling in order to avoid delaying circuit-switched (CS) signaling, at least until the PS signaling may not substantially effect CS domain activity. In an aspect, a progress of a CS call setup procedure may be monitored and the PS signaling or processing of such PS signaling may be resumed based on completion of a radio bearer setup step in the CS call setup procedure.

Abstract: A user equipment (UE) may use multiple subscriber identification modules (SIMs) in dual-SIM dual-active (DSDA) communications. The A DSDA UE may support identification of a set of available radio frequency (RF) resources for communications, where the set of available RF resources include multiple RF components (e.g., transmit/receive antennas), RF baseband resources (e.g., processing resources that support processing and decoding of transmissions), or combinations thereof. The set of available resources may be shared between multiple SIMS, and the UE may identify different resource partitions of the set of available resources, with different resource partitions used to provide concurrent communications of both the first SIM and the second SIM based on parameters of each SIM.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a broadcast or multicast (broadcast/multicast) application associated with a first radio access technology (RAT) while the UE is in a standalone mode for a second RAT; switch from the second RAT to the first RAT based at least in part on initiating the broadcast/multicast application; and switch from the first RAT to the second RAT based at least in part on failing to detect a communication associated with the broadcast/multicast application using the first RAT. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate on a primary carrier using a first antenna port. The UE may communicate on a secondary carrier using a second antenna port. The UE may determine whether to switch the secondary carrier from the second antenna port to the first antenna port based on a channel condition associated with the second antenna port. The UE may switch the secondary carrier from the second antenna port to the first antenna port based on a determination to switch the secondary carrier from the second antenna port to the first antenna port. Numerous other aspects are provided.

Abstract: Mobility management is described for simultaneous, multiple radio access technology (RAT) user equipments (UEs). When the UE detects a mobility event that would trigger transfer of a communication service from a first RAT to a second RAT, the UE determines whether there is an existing connection to a base station of the second RAT and uses cached measurement information related to this base station to influence or weight how the transfer is performed/handled/managed.

Abstract: A method of wireless communication defers measurement control reading of a SIB. The method includes determining whether a user equipment (UE) has been redirected to a first radio access technology (RAT) from a second RAT. The method also includes selectively reading a system information block (SIB) based on whether the UE was redirected to the first RAT from a second RAT.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, via a first subscriber service, at least one protocol data unit (PDU) session. The UE may receive a first internet protocol (IP) address associated with the first subscriber service. The UE may register the first subscriber service with an IP multimedia subsystem (IMS) network using the first IP address. The UE may register a second subscriber service with the IMS network using a second IP address, wherein the second subscriber service uses the at least one PDU session of the first subscriber service. Numerous other aspects are described.
