Methods and apparatus for wireless device positioning in multicarrier configurations

摘要

The described aspects include methods and apparatus for performing positioning for a user equipment (UE). The UE can communicate with a plurality of serving cells in a multicarrier configuration, and can indicate a plurality of serving cell identifiers corresponding to the plurality of serving cells in a message to a positioning server. The positioning server can obtain location information corresponding to at least a portion of a plurality of cells, or related eNBs, related to the plurality of serving cell identifiers, and can communicate the location information to the UE. The UE can perform positioning based at least in part on the location information.

主权项

1. A method for performing positioning for a user equipment (UE), comprising:
communicating with a plurality of serving cells in a multicarrier configuration, wherein the plurality of serving cells include a serving cell associated with a primary component carrier and one or more other serving cells associated with one or more secondary component carriers; indicating a plurality of serving cell identifiers corresponding to the plurality of serving cells in a message to a positioning server; receiving, from the positioning server, location information for each of the plurality of serving cell identifiers in response to the message, wherein the location information for one of the plurality of serving cell identifiers corresponding to a serving cell additionally corresponds to neighboring cells of the corresponding serving cell or other cells selected based at least in part on the corresponding serving cell; and performing positioning for a UE based at least in part on the received location information.
