    • 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.

    • Prioritized random access methods are proposed. According to an embodiment, random access attempts are classified into the priority levels according to delay requirements, and adedicated random access opportunities are reserved for different priority levels. A congestion detecting mechanism is introduced for such dedicated ranging (random access) opportunities. When congestion is detected by the base station, parameters or configurations of random access can be dynamically or temporarily modified through random access response message. Furthermore, a prioritized contention resolution is introduced to guarantee a high priority access is processed earlier than a low priority access. According to another embodiment, another prioritized contention resolution is introduced to reduce the impact of random access of a low priority M2M device upon H2H traffic.

    • A resource allocation method and a resource indication method for E-MBS system, and a mobile station using the same are proposed. The resource units of a first service flow are allocated following the end of the E-MBS MAP of the E-MBS region, along with the increasing of frequency domain index. When the edge of the E-MBS region in frequency domain is reached, the resource units of mth service flow are continued to be allocated from top frequency domain index in next time domain index, where m is an integer greater than or equal to 1. The resource units of m+1th service flow are allocated following the mth service flow, and such procedures are repeated until all service flows are allocated required resource units. The resource indication method indicates a specific service flow by absolute location in the E-MBS region formed based upon the resource allocation method.
    • 提出了一种用于E-MBS系统的资源分配方法和资源指示方法,以及使用该资源分配方法和资源指示方法。 随着E-MBS区域的E-MBS MAP的结束,第一服务流的资源单元以及频域索引的增加被分配。 当达到频域E-MBS区域的边缘时,第m个业务流的资源单元继续从下一个时域索引中的最高频域索引中分配,其中m是大于或等于1的整数。 在第m个服务流之后分配第m + 1个服务流的资源单元,并重复这些过程,直到所有服务流被分配所需的资源单元。 资源指示方法表示基于资源分配方法形成的E-MBS区域中的绝对位置的特定服务流。
