Abstract
In various implementations, methods, apparatuses, and computer-readable media are described for optimizing tune away carrier selection in a wireless communications system for position determination. The selection of a tune away carrier can be based on, for example, timing information related to pre-scheduled periods for receiving wireless position measurement signals, timing information related to pre-scheduled downlink data reception, timing information related to pre-scheduled uplink data transmission, etc.
Claims26
A method for wireless communication, the method comprising:
- identifying a set of candidate carriers, wherein the set of candidate carriers are associated with at least one of:
- downlink data reception, uplink data transmission, or any combination thereof;
- obtaining first timing information relating to one or more pre-scheduled tune away periods for receiving wireless position measurement signals;
- obtaining second timing information relating to pre-scheduled downlink data reception or pre-scheduled uplink data transmission for each candidate carrier of the set of candidate carriers;
- selecting, from the set of candidate carriers, a tune away carrier based on the first timing information and the second timing information;
- and
- during the one or more pre-scheduled tune away periods, controlling a wireless communication interface to:
- tune away from the tune away carrier to suspend downlink data reception or uplink data transmission using the tune away carrier, and
- tune to another carrier to receive the wireless position measurement signals.

A user equipment (UE), comprising:
- a wireless communication interface;
- a memory;
- and
- a processing unit communicatively coupled with the memory and the wireless communication interface and configured to cause the UE to:
- identify a set of candidate carriers, wherein the set of candidate carriers are associated with at least one of:
- downlink data reception, uplink data transmission, or any combination thereof;
- obtain first timing information relating to one or more pre-scheduled tune away periods for receiving wireless position measurement signals;
- obtain second timing information relating to pre-scheduled downlink data reception or pre-scheduled uplink data transmission for each candidate carrier of the set of candidate carriers;
- select, from the set of candidate carriers, a tune away carrier based on the first timing information and the second timing information;
- and
- during the one or more pre-scheduled tune away periods, control the wireless communication interface to:
- tune away from the tune away carrier to suspend downlink data reception or uplink data transmission using the tune away carrier, and
- tune to another carrier to receive the wireless position measurement signals.

An apparatus, comprising:
- means for identifying a set of candidate carriers, wherein the set of candidate carriers are associated with at least one of:
- downlink data reception, uplink data transmission, or any combination thereof;
- means for obtaining first timing information relating to one or more pre-scheduled tune away periods for receiving wireless position measurement signals;
- means for obtaining second timing information relating to pre-scheduled downlink data reception or pre-scheduled uplink data transmission for each candidate carrier of the set of candidate carriers;
- means for selecting, from the set of candidate carriers, a tune away carrier based on the first timing information and the second timing information;
- and
- means for during the one or more pre-scheduled tune away periods:
- tuning away from the tune away carrier to suspend downlink data reception or uplink data transmission using the tune away carrier, and
- tuning to another carrier to receive the wireless position measurement signals.
6 more elements
A non-transitory computer readable medium that stores a set of instructions which, when executed by a hardware processor, causes the hardware processor to:
- identify a set of candidate carriers, wherein the set of candidate carriers are associated with at least one of:
- downlink data reception, uplink data transmission, or any combination thereof;
- obtain first timing information relating to one or more pre-scheduled tune away periods for receiving wireless position measurement signals;
- obtain second timing information relating to pre-scheduled downlink data reception or pre-scheduled uplink data transmission for each candidate carrier of the set of candidate carriers;
- select, from the set of candidate carriers, a tune away carrier based on the first timing information and the second timing information;
- and
- during the one or more pre-scheduled tune away periods, control a wireless interface to:
- tune away from the tune away carrier to suspend downlink data reception or uplink data transmission using the tune away carrier, and
- tune to another carrier to receive the wireless position measurement signals.
