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.

摘要： 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.

摘要： The present invention discloses a transmission method and apparatus for a wireless communication system. The data transmission method comprises the following steps. A first data mapped in a QAM constellation pattern is transmitted in a first transmission. And a second data, which is reversion of the first data and mapped in said QAM constellation pattern, is retransmitted. In embodiment, the interleaved data is partially swapped based on a predetermined swapping pattern. In another embodiment, first interleaved data and second interleaved data are multiplexed per N bits, N is an integer larger than 1. Therefore, improvement of reliability at first transmission or retransmission in a wireless communication system can be achieved.

摘要： 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.
