Management of multiple subscriber identities in wireless communications
Systems, apparatus and methods for wireless communication are described, and more specifically, to techniques related to managing multiple subscriber identity modules (SIMs). One example method for wireless communication includes selecting, by a wireless device configured with at least a first subscriber identity module (SIM) and a second SIM, a primary SIM, performing a measurement of a reference signal configured for the primary SIM to obtain a primary result associated with the primary SIM, and reporting the primary result. The primary result can then be applied to other SIMs configured on the wireless device.
1 . A method of wireless communication, comprising:
selecting, by a wireless device configured with at least a first subscriber identity module (SIM) and a second SIM, a primary SIM;
performing a measurement of a reference signal configured for the primary SIM to obtain a primary result associated with the primary SIM; and
reporting, by the wireless device, the primary result,
wherein the method further comprises:
transmitting a first indication or a second indication,
wherein the first indication indicates that the primary result applies to a secondary SIM configured with the wireless device, wherein a received control signal indicates not to apply the primary result to the secondary SIM,
wherein the second indication, which is transmitted prior to the primary result being reported, indicates that a first measurement result associated with the first SIM applies to the second SIM or that a second measurement result associated with the second SIM applies to the first SIM.
2 . The method of claim 1 , wherein the measurement is a radio resource management (RRM) measurement, a radio frequency (RF) calibration measurement, or a positioning reference signal measurement.
3 . The method of claim 1 , wherein the measurement is configured for a serving cell or a neighboring cell.
4 . The method of claim 1 , wherein at least the first SIM and the second SIM are associated with a same mobile network operator (MNO) or with different MNOs.
5 . The method of claim 4 , wherein the first SIM is associated with a first MNO and the second SIM is associated with a second MNO different from the first MNO, and wherein the primary result is reported through a network device or a wireless device connected to both the first MNO and the second MNO.
6 . The method of claim 1 , further comprising:
reporting a secondary result associated with a secondary SIM configured with the wireless device, wherein the secondary result is set to the primary result.
7 . The method of claim 1 , wherein the second indication is transmitted to a primary public land mobile network (PLMN) associated with the primary SIM or to all PLMNs associated with the first SIM and the second SIM.
8 . A device for wireless communication, comprising:
at least one processor in a wireless device configured to cause the wireless device to:
select a primary subscriber identity module (SIM), wherein the wireless device is configured with at least a first SIM and a second SIM;
perform a measurement of a reference signal configured for the primary SIM to obtain a primary result associated with the primary SIM; and
report the primary result,
wherein the at least one processor is further configured to cause the wireless device to:
transmit a first indication or a second indication,
wherein the first indication indicates that the primary result applies to a secondary SIM configured with the wireless device, wherein a received control signal indicates not to apply the primary result to the secondary SIM,
wherein the second indication, which is transmitted prior to the primary result being reported, indicates that a first measurement result associated with the first SIM applies to the second SIM or that a second measurement result associated with the second SIM applies to the first SIM.
9 . The device of claim 8 , wherein the at least one processor is further configured to:
receive, from a network device, a message indicating the network device is shared between a plurality of MNOs.
10 . The device of claim 9 , wherein the message includes a plurality of PLMN values associated with the plurality of MNOs.
11 . The device of claim 9 , wherein the message is received via a Master Information Block (MIB), a System Information Block (SIB), a Synchronization Signal Block (SSB), or a Channel State Information reference signal (CSI-RS).
12 . The device of claim 9 , wherein the message indicates one or more frequency bands shared between at least two of the plurality of MNOs.
13 . The device of claim 9 , wherein the at least one processor is further configured to:
receive, from a second network device, a second message indicating the second network device is shared between a second plurality of MNOs.
14 . The device of claim 8 , wherein the wireless device is in a Radio Resource Control (RRC) idle, RRC inactive, or RRC connected mode.
15 . The device of claim 8 , wherein the primary SIM is selected at least based on a first RRC mode of the primary SIM.
16 . The device of claim 15 , wherein (a) the first RRC mode of the primary SIM is connected and a second RRC mode of a secondary SIM is idle or inactive, or (b) the first RRC mode of the primary SIM is idle and the second RRC mode of the secondary SIM is idle.
17 . The device of claim 8 , wherein the first SIM and the second SIM operate (a) on a same frequency range (FR), (b) on different FRs, or (c) under different cellular network generations.
18 . A method of wireless communication comprising:
transmitting, by a network device, a reference signal; and
receiving, from a wireless device configured with at least a first subscriber identity module (SIM) and a second SIM, a primary measurement result of the reference signal,
wherein the primary measurement result is associated a primary SIM of the wireless device,
wherein the method further comprises:
receiving, from the wireless device, a first indication or a second indication,
wherein the first indication indicates that the primary measurement result applies to a secondary SIM configured with the wireless device, wherein a received control signal indicates not to apply the primary measurement result to the secondary SIM,
wherein the second indication, which is received prior to the primary measurement result being received, indicates that a first measurement result associated with the first SIM applies to the second SIM or that a second measurement result associated with the second SIM applies to the first SIM.
19 . The method of claim 18 , wherein the primary measurement result applying to the secondary SIM enables an operation of the secondary SIM based on a periodicity of the primary SIM, wherein the operation comprises the secondary SIM being configured to:
perform, at the periodicity of the primary SIM, a measurement of the reference signal, or
report, at the periodicity of the primary SIM, a result associated with the measurement.
20 . The method of claim 18 , wherein a measurement associated with the primary measurement result is a radio resource management (RRM) measurement, a radio frequency (RF) calibration measurement, or a positioning reference signal measurement.
