Abstract

A method of wireless communication by a user equipment (UE) capable of supporting multiple subscriptions, includes measuring, with a first of the multiple subscriptions, neighbor cells of at least one other subscription of multiple subscriptions. The method also includes storing measurement results from measuring the neighbor cells in a common measurement results database, while avoiding duplicates. The method further includes reporting, with a subscription for which a neighbor is configured by a network, the measurement results from the common measurement results database.

First claim

What is claimed is:

1 . A method of wireless communication by a user equipment (UE) capable of supporting a plurality of subscriptions, comprising:
measuring, with a first of the plurality of subscriptions, neighbor cells of at least one other subscription of the plurality of subscriptions; storing measurement results from measuring the neighbor cells in a common measurement results database, while avoiding duplicates; and reporting, with a subscription for which a neighbor is configured by a network, the measurement results from the common measurement results database.

2 . The method of claim 1 , in which the first of the plurality of subscriptions is connected and the at least one other subscription of the plurality of subscriptions is idle and the measuring occurs in network configured gaps of the connected subscription.

3 . The method of claim 1 , in which the first of the plurality of subscriptions is connected and the at least one other subscription of the plurality of subscriptions is idle and the measuring occurs in a connected mode discontinuous reception (C-DRX) off duration of the connected subscription.

4 . The method of claim 1 , in which the first of the plurality of subscriptions is idle and the idle subscription measures its own neighbors, neighbors of other idle subscriptions of the plurality of subscriptions, and neighbors of connected subscriptions of the plurality of subscriptions.

5 . The method of claim 1 , in which the first of the plurality of subscriptions is connected and the connected subscription measures its own neighbors, neighbors of other connected subscriptions of the plurality of subscriptions, and neighbors of idle subscriptions of the plurality of subscriptions.

6 . The method of claim 1 , in which the first of the plurality of subscriptions uses at least one spare antenna chain to perform multiple neighbor measurements simultaneously.

7 . The method of claim 1 , in which measuring of common neighbors among the plurality of subscriptions is not duplicated by any other subscription of the plurality of subscriptions.

8 . The method of claim 1 , further comprising selecting target neighbor cells for measurement from the common measurement results database.

9 . The method of claim 1 , further comprising measuring neighbor cells for all of the other subscriptions of the plurality of subscriptions.

10 . The method of claim 1 , further comprising alternating measuring of neighbor cells with at least one other of the plurality of subscriptions.

11 . An apparatus for wireless communication by a user equipment (UE) capable of supporting a plurality of subscriptions, comprising:
a memory; and at least one processor coupled to the memory, the at least one processor configured:
to measure, with a first of the plurality of subscriptions, neighbor cells of at least one other subscription of the plurality of subscriptions;
to store measurement results from measuring the neighbor cells in a common measurement results database, while avoiding duplicates; and
to report, with a subscription for which a neighbor is configured by a network, the measurement results from the common measurement results database.

12 . The apparatus of claim 11 , in which the first of the plurality of subscriptions is connected and the at least one other subscription of the plurality of subscriptions is idle and the measuring occurs in network configured gaps of the connected subscription.

13 . The apparatus of claim 11 , in which the first of the plurality of subscriptions is connected and the at least one other subscription of the plurality of subscriptions is idle and the measuring occurs in a connected mode discontinuous reception (C-DRX) off duration of the connected subscription.

14 . The apparatus of claim 11 , in which the first of the plurality of subscriptions is idle and the idle subscription measures its own neighbors, neighbors of other idle subscriptions of the plurality of subscriptions and neighbors of connected subscriptions of the plurality of subscriptions.

15 . The apparatus of claim 11 , in which the first of the plurality of subscriptions is connected and the connected subscription measures its own neighbors, neighbors of other connected subscriptions of the plurality of subscriptions and neighbors of idle subscriptions of the plurality of subscriptions.

16 . The apparatus of claim 11 , in which the first of the plurality of subscriptions uses at least one spare antenna chain to perform multiple neighbor measurements simultaneously.

17 . The apparatus of claim 11 , in which the at least one processor is further configured to measure common neighbors among the plurality of subscriptions without duplicating measuring by any other subscription of the plurality of subscriptions.

18 . The apparatus of claim 11 , in which the at least one processor is further configured to select target neighbor cells for measurement from the common measurement results database.

19 . The apparatus of claim 11 , in which the at least one processor is further configured to measure neighbor cells for all of the other subscriptions of the plurality of subscriptions.

20 . The apparatus of claim 11 , in which the at least one processor is further configured to alternate measuring of neighbor cells with at least one other of the plurality of subscriptions.

21 . An apparatus for wireless communication by a user equipment (UE) capable of supporting a plurality of subscriptions, comprising:
means for measuring, with a first of the plurality of subscriptions, neighbor cells of at least one other subscription of the plurality of subscriptions; means for storing measurement results from measuring the neighbor cells in a common measurement results database, while avoiding duplicates; and means for reporting, with a subscription for which a neighbor is configured by a network, the measurement results from the common measurement results database.

22 . The apparatus of claim 21 , in which the first of the plurality of subscriptions is connected and the at least one other subscription of the plurality of subscriptions is idle and the means for measuring measures in network configured gaps of the connected subscription.

23 . The apparatus of claim 21 , in which the first of the plurality of subscriptions is connected and the at least one other subscription of the plurality of subscriptions is idle and the means for measuring measures in a connected mode discontinuous reception (C-DRX) off duration of the connected subscription.

24 . The apparatus of claim 21 , in which the first of the plurality of subscriptions is idle and the idle subscription includes means for measuring its own neighbors, neighbors of other idle subscriptions of the plurality of subscriptions, and neighbors of connected subscriptions of the plurality of subscriptions.

25 . The apparatus of claim 21 , in which the first of the plurality of subscriptions is connected and the connected subscription comprises means for measuring its own neighbors, neighbors of other connected subscriptions of the plurality of subscriptions, and neighbors of idle subscriptions of the plurality of subscriptions.

26 . The apparatus of claim 21 , in which the first of the plurality of subscriptions uses at least one spare antenna chain to perform multiple neighbor measurements simultaneously.
