Probability calculation of RAT candidate

摘要

An apparatus (200) for use in a telecommunications system. The apparatus (200) comprising a memory (240) and a controller (210). The controller (210) is configured to receive a radio frequency bandwidth and identify a first candidate carrier frequency (710) from the received a radio frequency bandwidth. The controller is further configured to, for a first potential radio access technology determine a probability estimate (Prob) for the first candidate carrier frequency (710) being a carrier frequency of the first potential radio access technology, where in the probability estimate is based on a received power in a transmission band of the first potential radio access technology having the candidate carrier frequency (710) and on a received power in a guard band of the first potential radio access technology having the candidate carrier frequency and from this select a radio access technology based on the probability estimate (Prob) for the candidate carrier frequency (710).

1. An apparatus for use in a telecommunications system, said apparatus comprising:
a memory, and a controller, configured:
to receive a signal within a radio frequency bandwidth;to identify a first candidate carrier frequency in the received radio frequency bandwidth, based on the signal;for each among potential radio access technologies, to determine a probability estimate for the first candidate carrier frequency being a carrier frequency of the potential radio access technology, where in the probability estimate is based on a channel power received in a channel band of the potential radio access technology, the channel band including the first candidate carrier frequency, and on a guard power received in a guard band of the channel band according to the potential radio access technology; andto select one of the potential radio access technologies based on determined probability estimates related to the first candidate carrier frequency.
