Abstract: Aspects of the present disclosure provide techniques for coordinated tune away for multiple subscriber identity module (SIM) devices. A method by a user equipment includes communicating with a first base station (BS) of a first radio access network (RAN) in a connected mode using a first subscription associated with a first SIM of the UE, wherein the UE: includes a second subscription associated with a second SIM for communicating with a second BS of a second RAN, and operates in an idle mode associated with the second subscription while communicating using the first subscription; determining a tune away associated with the first RAN will occur to allow the UE to perform one or more first actions associated with the second subscription; and transmitting information to the first BS indicating the tune away and a request to suspend one or more second actions associated with the first subscription.

Abstract: Aspects relate to mechanisms for wireless communication device to transmit indications of channel qualities for uplink and downlink transmission involving multi-subscriber identification module (MSIM) devices. A user equipment (UE) having a first subscription and a second subscription is provided. The UE identifies one or more base-band resource outage periods associated with the first subscription based on a utilization of at least partially shared base-band resources by the second subscription. The UE also transmits one or more medium access control (MAC) control elements (MAC-CEs) to a base station requesting a modification of one or more data transmission timing parameters of one or more data elements associated with the first subscription based on the one or more base-band resource outage periods associated with the first subscription.

Abstract: A method of wireless communication by a user equipment (UE) includes receiving a configuration for dynamic spectrum sharing (DSS) operation where a first radio access technology (RAT) and a second RAT share spectrum. The configuration includes channel parameters associated with the first RAT. The method includes determining, based on the configuration, a first set of synchronization signal blocks (SSBs) that will not be transmitted via the second RAT and a second set of SSBs that will be transmitted via the second RAT. The method further includes refraining from performing a cell search on the first set of SSBs that was determined to not be transmitted via the second RAT. The method includes performing the cell search on the second set of SSBs that was determined to be transmitted via the second RAT.

Abstract: Mechanisms for uplink (UL) scheduling in dual connectivity scenarios are provided. According to one aspect of the present disclosure, a method of wireless communication performed by a user equipment (UE) includes: receiving, in an uplink (UL) buffer, first UL data for transmission to at least one base station (BS) via a first path and a second path, wherein the first path and the second path are associated with a dual connectivity communication mode; transmitting, to a first BS on the first path, a first scheduling request for the first UL data; and refraining, based on a time duration between the receiving the first UL data in the buffer and a tune-away gap on the second path, from transmitting a second scheduling request for the first UL data on the second path.

Abstract: Certain aspects of the present disclosure provide a technique for signaling user equipment (UE) assistance information (UAI) indicating a preferred set of connected discontinuous reception (CDRX) parameters, a start offset, and/or a slot offset to a network entity. For example, a UE signals the UAI when operating in a dual connectivity mode involving a new radio (NR) and a long term evolution (LTE). The UE signals the UAI via a new information element (IE). The UE receives a new set of CDRX parameters from the network entity based on the UAI. The UE uses the new set of CDRX parameters for a CDRX operation.

Abstract: Aspects relate to a method of wireless communication at a user equipment (UE). The method includes receiving a set of one or more transmissions in an assigned bandwidth part (BWP) of a set of bandwidth parts (BWPs) from a base station (BS), wherein the set of one or more transmissions includes data addressed to the UE; after missing a reception of a second set of one or more transmissions from the BS following the set, receiving a third set of one or more transmissions in the assigned BWP from the BS, wherein the third set does not include data addressed to the UE; and determining whether a fourth set of one or more transmissions from the BS in one or more unassigned BWPs of the set of BWPs includes data addressed to the UE in response to the third set not including data addressed to the UE.

Abstract: Aspects presented herein may enable a UE to guide its user to return to an area with cellular coverage when the UE is about to become out-of-service (OOS) and/or after the UE becomes OOS. In one aspect, a UE detects that the UE is within a threshold distance of an edge cell of a set of cells for a network. The UE records a set of locations of the UE with a cellular coverage based on detecting that the UE is within the threshold distance of the edge cell. The UE detects that the UE is OOS or soon to be OOS of the network. The UE indicates at least one location in the set of locations of the UE in response to a detection that the UE is OOS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) detects a collision between a duration in time domain configured to receive downlink data for a dedicated data subscription (DDS) subscription of the MSIM UE and a first paging occasion configured to receive a paging message for a non-DDS (n-DDS) subscription of the MSIM UE. The UE may then monitor a second paging occasion different from the first paging occasion for the paging message, the second paging occasion configured to avoid collision with the duration in time domain.
