Supporting version negotiation for positioning for terminals in a wireless network

An apparatus for wireless communication, comprising:

• at least one processing unit configured to prepare a message with a message segment including a version of a protocol used to encode the message and a compatibility level associated with inter-operable protocol versions, wherein different compatibility levels indicate non-compatibility between protocol versions, and to transmit the message with the message segment including the version and the compatibility level.

An apparatus for wireless communication, comprising:

• means for preparing a message with a message segment including a version of a protocol used to encode the message and a compatibility level associated with inter-operable protocol versions, wherein different compatibility levels indicate non-compatibility between protocol versions;
• and
• means for transmitting the message with the message segment including the version and the compatibility level.

A non-transitory computer-readable medium including program code stored thereon, comprising:

• program code to cause at least one computer to prepare a message with a message segment including a version of a protocol used to encode the message and a compatibility level associated with inter-operable protocol versions, wherein different compatibility levels indicate non-compatibility between protocol versions;
• and
• program code to transmit the message with the message segment including the version and the compatibility level.

An apparatus for wireless communication, comprising:

• at least one processing unit configured to receive a message with a message segment including a version of a protocol used to encode the message and a compatibility level associated with inter-operable protocol versions, wherein different compatibility levels indicate non-compatibility between protocol versions, to compare the compatibility level included in the message that was received to an internal compatibility level, to prepare a response message with a message segment including the internal compatibility level, and to transmit the response message with the message segment including the internal compatibility level.
