摘要： A method, an apparatus, and a computer program product for wireless communication are provided in connection with LTE based paging for peer discovery. In one example, an eNodeB is equipped to receive a message including a D2D discovery notification for a UE, determine that the UE is in an idle mode, and transmit a paging notification to the UE including the D2D discovery notification. In another example, a UE is equipped to receive, from an eNodeB, a paging notification including a D2D discovery notification, determine, while in idle mode, that the D2D discovery notification is successfully decoded, and transmit an ACK to the eNodeB using a RACH sequence on a PRACH.

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.

摘要： Pilot signal transmission sequences and methods for use in a multi-sector cell. Pilots in different sectors are transmitted at different known power levels. In adjacent sectors a pilot is transmitted while no pilot is transmitted in the adjoining sector. This represents transmission of a NULL pilot signal. A cell NULL is also supported in which NULL pilots are transmitted in each sector of a cell at the same time. Multiple pilot signal measurements are made. At least two channel quality indicator values are generated from measurements corresponding to at least two pilot signals of different power levels. The two values are transmitted back to the base station which uses both values to determine the transmit power requited to achieve a desired SNR at the wireless terminal. The wireless terminal also reports information indicating its location to a sector boundary.

摘要： A method for reducing the peak-to-average ratio in an OFDM communication signal is provided. The method includes defining a constellation having a plurality of symbols, defining a symbol duration for the OFDM communication signal, and defining a plurality of time instants in the symbol duration. A plurality of tones are allocated to a particular communication device, and a discrete signal is constructed in the time domain by mapping symbols from the constellation to the time instants. A continuous signal is generated by applying an interpolation function to the discrete signal such that the continuous signal only includes sinusoids having frequencies which are equal to the allocated tones.

摘要： Wireless terminals and base stations support multiple modes of control channel operation wherein wireless terminals are allocated different amounts of uplink resources for reporting control information. A set of control channel segments is utilized by a wireless terminal to communicate uplink control information reports to its serving base station attachment point. Full tone and split-tone modes of control channel operation are supported. In full tone mode, a single wireless terminal is allocated each of the control channel segments associated with a single logical tone. In split tone mode, control channel segments associated with a single logical tone are allocated between different wireless terminals, with each of the multiple wireless terminals receiving a different non-overlapping subset of the control channel segments. Logical control channel tones can be dynamically reallocated for full-tone mode use or split tone mode use.
