Abstract: A method and apparatus for estimating a frequency offset of received signals. The receiving device receives a plurality of pilot signals form a transmitting device, and determines an un-aliased frequency offset estimate based on the received pilot signals. The receiving device further determines a low-noise frequency offset estimate based on the received pilot signals, wherein the low-noise frequency offset estimate is blow a threshold noise level. The receiving device then generates a hybrid frequency offset estimate based at least in part on the un-aliased and low-noise frequency offset estimates, wherein the hybrid frequency offset estimate is un-aliased and has a lower estimation noise than the un-aliased frequency offset estimate.

Abstract: Access terminals and network nodes are adapted to conduct access terminal registrations. In one example, an access terminal may obtain a data message for transmission, and registration information associated with the access terminal. The access terminal may send a message including the data message and the registration information. A network node can receive a message from an access terminal, where the received message includes a data message and access terminal registration information. The network node can register the access terminal with a network based on the access terminal registration information included in the received message. The network node can also process the data message included in the received message. Other aspects, embodiments, and features are also claimed and described.
