    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.

    摘要: A method of providing resource unit based data block partitioning may include determining, for a bit stream to be encoded in a coding scheme including an upper layer coding and a physical layer coding, whether upper layer coding is enabled. The method may further include, in response to the upper layer coding being enabled, partitioning the bit stream into one or more blocks for forward error correction coding. The one or more blocks may have a block size determined based on a size of a resource unit. The resource unit size may correspond to one or more units predefined in the physical layer for the resource allocation. A corresponding apparatus is also provided.
