Claim Text:
1. A method of compensating timing measurement values obtained in a wireless communication network having multiple carriers operating at different carrier frequencies, said method implemented in a single first node configured for operation in the wireless communication network and comprising: obtaining, by the single first node, a first timing measurement value for a first radio signal transmitted by the single first node at a first carrier frequency to a single second node; obtaining, by the single first node, a second timing measurement value for a second radio signal transmitted by the single first node at a second carrier frequency to the single second node, the second radio signal being associated with the first radio signal; determining, by the single first node, whether timing compensation is needed for either or both of the first timing measurement value or the second timing measurement value, based at least in part, on an association with an emergency call and a frequency distance between the first carrier frequency and the second carrier frequency; responsive to determining that timing compensation is needed, deriving, by the single first node, a compensation value based on frequency-dependent propagation differences between the first carrier frequency and the second carrier frequency, wherein adjusting either or both of the first timing measurement value or the second timing measurement value using the compensation value substantially accounts for the frequency-dependent propagation differences; and providing, by the single first node to the single second node or other node configured for operation in the wireless communication network, the compensation value for use in compensating either or both of the first timing measurement value or the second timing measurement value when used in processing by the single second node or the other node dependent on either or both of the first timing measurement value or the second timing measurement value.
