摘要： Aspects relate to mitigating interference in a communication network that does not employ a centralized scheduler. A transmission sent on a subset of resources is evaluated to determine a number of communication pairs that have selected that subset of resources on which to transmit. If there are a large number of communication pairs transmitting on that subset, the transmission is ignored by a receiving device. The number of degrees of freedom that contain energy on the subset is evaluated to determine if an expected number of degrees of freedom that should have energy is met or exceeded. If the expected threshold number is met or exceed, the transmission is decoded by the receiving device, else the transmission is not decoded.

摘要： Techniques for discovering one or more nodes in a communication system are provided. A node may receive one or more discovery messages during a first occurrence of a periodic discovery interval. The node may determine a duration of a subsequent occurrence of the periodic discovery interval based on the one or more received discovery messages. The node may adjust the duration for the subsequent occurrence of the periodic discovery interval based on the determined duration.

摘要： Techniques for transmitting information in a long term evolution (LTE) wireless communication network are disclosed. A base station may receive a first user equipment (UE) expression and first UE location information of a UE seeking peers. The base station may also receive a second UE expression and second UE location information of at least one of the peers. In accordance with the first and second UE expressions and the first and second UE location information, the base station may match ones of the peers proximate to the UE. The base station may transmit, using a data exchange efficiency technique, information to alert the UE to the presence of the peers. This transmission may comprise wide area network (WAN)-specific signaling.

摘要： Various methods and apparatus are directed to achieving timing synchronization and propagating timing information pertaining to an external, e.g., non Wi-Fi, timing signal source. In some embodiments, a mobile communications device receives and processes a timing signal, e.g., a first Wi-Fi beacon, which is propagating timing information about an external timing signal from a device which directly received the external timing signal. Thus, a mobile wireless communications device achieves timing synchronization with respect to an external timing signal which it is unable to receive directly. In various embodiments, the mobile communications device may, and sometimes does, further propagate the timing information about the external timing signal, e.g., via a second Wi-Fi beacon signal which it generates and transmits. Synchronization with respect to an external signal source facilitates longer sleep states and decreased power consumption.

摘要： In an ad hoc peer-to-peer type network during peer discovery, information relating to users of various devices is broadcast to other devices in the network, which can compromise privacy of the users. Instead of announcing a public identifier that might be known by a multitude of individuals, the user device announces a private identifier that might be known to, or determined by, a select few individuals. The individuals selected can be given a key to determine the private identifier associated with a public identifier, or vice versa, wherein that key can have a validity range or a period of time, after which the key expires. Prior to the expiration of the key, the selected individuals, through their respective devices, can detect a corresponding user and/or device by the current private identifier being announced, thus mitigating the number of people that are aware of the user's presence.

摘要： Methods and apparatus for wireless communications in regional networks, e.g., ad hoc peer to peer networks, are described. Wireless communications devices transmit and monitor for presence indicator signals broadcast from other peer communications devices in its local vicinity. A wireless communications device maintains a list of discovered devices in its vicinity. A first wireless communications device transmits a paging signal directly over an airlink to a second communications device, which is on its list and to which it desires to send data units, e.g., user data in a peer to peer traffic segment. In response to a received paging response signal from the second device, the first device transmits data units, intended for the second device, to a third device, which acts as an intermediary node. The power level for the data unit signal is controlled to be lower than the power level used for the paging signal. FIG. 4

摘要： Techniques for efficiently sending reports in a wireless communication system are described. Reports may be sent repetitively in accordance with a reporting format. A terminal receives an assignment of a control channel used to send reports and determines a reporting format to use based on the assignment. The reporting format indicates a specific sequence of reports sent in specific locations of a control channel frame. The terminal generates a set of reports for each reporting interval and arranges the set of reports in accordance with the reporting format. The terminal repetitively sends a plurality of sets of reports in a plurality of reporting intervals. Reports may also be sent adaptively based on operating conditions. An appropriate reporting format may be selected based on the operating conditions of the terminal, which may be characterized by environment (e.g., mobility), capabilities, QoS, and/or other factors.
