Abstract: Techniques for signaling capabilities of a mobile station using a capabilities index as well as a fall back mechanism in case of system failure. The capabilities index can represent multiple capabilities of the mobile station. A mobile station can signal to the base station the mobile station's capabilities using a capability index. A base station can interpret the capability index from the mobile station to learn the capabilities of the mobile station. The base station can signal to the mobile station the base station's supported capabilities using a capabilities index. The capabilities utilized between the base station and mobile station are set according to the base station's signaled capabilities.

Other embodiments are also disclosed and claimed.

Abstract: In a wireless network, simultaneous support of distributed and contiguous sub-carrier allocation may be accomplished in the same sub-frame or time zone. Techniques are described herein that can be used to allocate distributed and/or contiguous basic (physical) resource blocks to users by specifying a codebook index and parent node.

Sub-channels may be represented as nodes and may be grouped to include a parent node and child nodes. By specifying a code book to use and a parent node, the channel quality indicator of the parent and children nodes can be indicated.

Abstract: Machine-readable media, methods, apparatus and system for transmitting ACK/NACK signal in a wireless communication system are described.
