摘要： A carrier assignment method, a multi-carrier base station and a wireless communication device using the same are proposed. The carrier assignment method is adapted for assigning carriers in a paging group for an ABS with multi-carriers, and includes the following step. At least two paging carriers is assigned in a paging group, where all assigned carriers belonging to a paging group are in the same frequency band. Also, small but close frequency bands are grouped into a super band, where different carriers in different super bands are assigned into different paging groups. The wireless communication device determines the paging carrier index for itself by a mapping function of a mobile identification and the number of carriers. The paging message for the wireless communication device is sent only on the paging carrier corresponding to the determined paging carrier index.

摘要： A method for estimating frequency offset is provided. First, a baseband signal with a preamble featuring quasi-periodic property is received. Next, the quasi-periodic property of the preamble of the received baseband signal is reconstructed by interpolation. Next, a frequency offset angle is estimated by using the reconstructed baseband signal. The accuracy of estimating frequency offset is increased because of better reconstructed quasi-periodic property of the preamble.

摘要： A pilot selection method adapted for selecting rank-2 pilot patterns for a macrocell advanced base station (ABS), a femtocell ABS and a non-macrocell and non-femtocell ABS is proposed along with a wireless communication system and a base station thereof. Different rank-2 pilot pattern is selected for a femtocell ABS from its overlay macrocell ABS and non-macrocell and non-femtocell ABS rank-2 pilot patterns. Another pilot selection method for selecting a rank-1 pilot pattern for a femtocell ABS co-located with at least a macrocell ABS is also proposed. Different rank-1 pilot pattern is selected for a femtocell ABS from its overlay macrocell ABSs using rank-1 and/or rank-2 pilot patterns, where some of the macrocell ABSs can use rank-2 pilot patterns and the rest of the macrocell ABSs just use rank-1 pilot patterns. Also, different rank-1 pilot pattern is selected for the femtocell ABS from its neighboring femtocell ABSs using rank-1 pilot patterns.
