Abstract

A user equipment may, based on a tuneaway, start suspend a first timer and/or deactivate a first counter and may, based on a tuneback, resume the first timer and/or activate the first counter. The first timer and first counter may be configured to be used to determine that a sufficiently large number of sufficiently closely timed beam failure indications have been received and, in response to that determination, initiate an access procedure. A user equipment may also identify an overlap of a timing of at least one radio access technology event and a timing of a tuneaway gap and may, based on the identified overlap of the timing of at least one radio access technology event and the timing of the tuneaway gap, modify the timing of the at least one radio access technology event or the timing of the tuneaway gap.

Claims (63)

1. An apparatus for wireless communication, the apparatus comprising:

one or more processors configured with processor-executable instructions to perform operations comprising:

performing a tuneaway;

performing a tuneback; and

based on the tuneback:

measuring a beam quality of a first beam;

determining that the beam quality of the first beam fails to satisfy a beam-quality threshold;

determining that a time to a scheduled beam reporting satisfies a first threshold; and

based on determining that the beam quality of the first beam fails to satisfy the beam-quality threshold and determining that the time to the scheduled beam reporting satisfies the first threshold, perform beam reporting.

2. An apparatus for wireless communication, the apparatus comprising:

one or more processors configured with processor-executable instructions to perform operations comprising:

identifying an overlap of a timing of at least one radio access technology event and a timing of a tuneaway gap, wherein the at least one radio access technology event comprises a scheduled beam measurement and reporting; and

based on the identified overlap of the timing of at least one radio access technology event and the timing of the tuneaway gap, modifying the timing of the at least one radio access technology event or the timing of the tuneaway gap, wherein the modifying the timing of the at least one radio access technology event or the timing of the tuneaway gap comprises rescheduling the beam measurement and reporting to occur before the tuneaway gap or after the tuneaway gap.

3. An apparatus for wireless communication, the apparatus comprising:

one or more processors configured with processor-executable instructions to perform operations comprising:

identifying an overlap of a timing of at least one radio access technology event and a timing of a tuneaway gap, wherein the at least one radio access technology event comprises a beam switch that is likely to occur in response to a scheduled beam measurement and reporting; and

based on the identified overlap of the timing of at least one radio access technology event and the timing of the tuneaway gap, modifying the timing of the at least one radio access technology event or the timing of the tuneaway gap, wherein the modifying the timing of the at least one radio access technology event or the timing of the tuneaway gap comprises:

rescheduling the beam measurement and reporting such that the beam switch occurs before the tuneaway gap; or

rescheduling the beam measurement and reporting to occur after the tuneaway gap such that the beam switch occurs after the tuneaway gap.

4. An apparatus for wireless communication, the apparatus comprising:

one or more processors configured with processor-executable instructions to perform operations comprising:

identifying an overlap of a timing of at least one radio access technology event and a timing of a tuneaway gap, wherein the at least one radio access technology event comprises a beam switch point; and

based on the identified overlap of the timing of at least one radio access technology event and the timing of the tuneaway gap, modifying the timing of the at least one radio access technology event or the timing of the tuneaway gap, wherein the modifying the timing of the at least one radio access technology event or the timing of the tuneaway gap comprises rescheduling the beam switch point to occur after the tuneaway gap.

5. An apparatus for wireless communication, the apparatus comprising:

one or more processors configured with processor-executable instructions to perform operations comprising:

identifying an overlap of a timing of at least one radio access technology event and a timing of a tuneaway gap, wherein the at least one radio access technology event comprises beam management during acquisition; and

based on the identified overlap of the timing of at least one radio access technology event and the timing of the tuneaway gap, modifying the timing of the at least one radio access technology event or the timing of the tuneaway gap, wherein the modifying the timing of the at least one radio access technology event or the timing of the tuneaway gap comprises preventing a tuneaway of the tuneaway gap from occurring during acquisition of a frequency and allowing the tuneaway of the tuneaway gap between acquisition of different frequencies.

6. An apparatus for wireless communication, the apparatus comprising:

one or more processors configured with processor-executable instructions to perform operations comprising:

receiving a beam failure indication, which indicates a failure of a first beam;

determining that the beam failure indication was received;

based on determining that the beam failure indication was received:

starting a first timer; and

incrementing a first counter indicating a number of received beam failure indications;

based on a tuneaway:

suspending the first timer; or

deactivating the first counter; and

based on a tuneback:

resuming the first timer; or

activating the first counter.

7. The apparatus of claim 6 , wherein the operations further comprise:

determining that the first counter satisfies a threshold; and

based on determining that the first counter satisfies the threshold, initiating a random access procedure.

8. The apparatus of claim 6 , wherein the operations further comprise:

determining that the first timer has expired; and

based on determining that the first timer has expired, resetting the first counter.

9. The apparatus of claim 6 , wherein the operations further comprise:

performing the tuneaway; and

performing the tuneback.

10. The apparatus of claim 6 , wherein the operations further comprise:

based on the tuneback:

measuring a beam quality of the first beam;

determining that the beam quality of the first beam fails to satisfy a beam-quality threshold;

determining that a time to a scheduled beam reporting satisfies a first threshold; and

based on determining that the beam quality of the first beam fails to satisfy the beam-quality threshold and determining that the time to the scheduled beam reporting satisfies the first threshold, perform beam reporting.

11. The apparatus of claim 6 , wherein the operations further comprise: based on the tuneback:

determining that a beam quality of the first beam has failed to satisfy a beam quality threshold for a threshold duration; and

based on determining that the beam quality of the first beam has failed to satisfy the beam quality threshold for the threshold duration, triggering an initiation of a random access procedure.

12. The apparatus of claim 6 , wherein the operations further comprise: based on the tuneback:

determining that a beam quality of the first beam has failed to satisfy a beam quality threshold for a threshold duration; and

based on determining that the beam quality of the first beam has failed to satisfy the beam quality threshold for the threshold duration, setting the first counter to a threshold-satisfying value;

determining that the first counter satisfies a first threshold; and

based on determining that the first counter satisfies the first threshold, initiating a random access procedure.
