Abstract: Methods and apparatus may be used to provide reliable multicast or broadcast for peer-to-peer (P2P) communications. A wireless transmit/receive unit (WTRU) may receive a medium access control (MAC) data frame. The MAC data frame may indicate a flexible acknowledgement (ACK) type (e.g., a subset of peers, a single peer, location based, context based, and/or packet type based). The MAC data frame may indicate an ACK sequence. The ACK sequence may indicate an ACK transmission sequence among peers. The WTRU may determine whether to send an ACK message based on the flexible ACK type and/or the ACK sequence. The WTRU may receive an ACK message from a peer. The WTRU may send the ACK message when it is determined that the ACK message should be sent.

Abstract: Frame structures may be designed and channels may be allocated in a manner to support multi-hop for fully distributed and infrastructure-less peer-to-peer communications in proximity. Frame structures may have a dedicated multi-hop period near the end of a superframe.

Abstract: In peer-to-peer (P2P) communications, it has been recognized herein that various context information needs to be exchanged between peer devices (PDs) or between different layers/protocols within a peer device (PD). Various embodiments described herein address how to design effective management functions, services, and primitives for context management across and/or within different protocol layers to enable context-aware peer-to-peer communications in proximity. This disclosure proposes multiple embodiments for cross-layer context management in context-aware peer-to-peer communication in proximity. For example, embodiments described herein provide context management to efficiently enable context-aware P2P communications, such as, for example, social networks.

Abstract: Disclosed are methods and systems for Semantics Node functions which provide semantics support in machine-to-machine systems.

Abstract: Methods and systems are disclosed for determining context information for one or more peers to be used in a peer discovery and/or peer association process(es) and/or to otherwise facilitate P2P proximity communications. For example, a method for determining peer context information may include receiving a context-aware identifier (CAID). The CAID may include one or more items of context information associated with the peer in addition to an indication of an identity of the peer. A first portion of the CAID may be decoded to determine a first item of context information associated with the peer. The first portion of the CAID may be decodable without having to process a payload portion of the message. It may be determined whether to continue processing one or more of the CAID or the message based on the first item of context information. The CAID may be used in discovery and/or association procedure(s).

The first device receives an acknowledgement frame including a number of pending and approved data frames. The first device may receive a plurality of data frames in response to the acknowledgement frame.
