20120058745 | ADVERTISING METHODS AND APPARATUS FOR USE IN A WIRELESS COMMUNICATIONS SYSTEM - Methods and apparatus related to communicating advertisements and/or service announcements to devices in a communications system are described. In various embodiments mobile devices are used as mobile advertisement transmission platforms. Advertisements may be downloaded to the wireless communications device along with transmission constraints. Transmission of an advertisement is made when a transmission constraint, e.g., target audience constraint is satisfied. The wireless terminal may change its transmission frequency, coding rate and/or other transmission characteristics to satisfy a transmission constraint and/or optimize revenue. The mobile device reports advertisements transmissions to a network device, e.g., advertisement server and the owner of the device is compensated for the transmissions. Transmission constraints may involve a number of devices to be reached, the type of devices to be reached, and/or other constraints relating to the demographics of device users. Information may be obtained from peer discovery signals and used to determine if a constraint is satisfied. | 03-08-2012 |

20120106751 | METHODS AND APPARATUS FOR WIRELESS MICROPHONE SYNCHRONIZATION - Methods and apparatus related to timing synchronization used in a wireless microphone system to reduce and/or minimize interference are described. A wireless microphone receiver in some embodiments performs open loop timing control based on signals from an adjacent wireless microphone receiver and participates in closed loop timing control of wireless microphone transmitters which communicate with the particular wireless microphone receiver. The closed loop timing control includes instructing individual wireless microphone transmitters to advance or retard their symbol timing so that symbols transmitted by different wireless microphone transmitters are received in a synchronized manner at the wireless microphone receiver. The closed loop timing control allows a wireless microphone receiver to control wireless microphone transmitters to take into consideration their different distances to the receiver and the differing transmission times associated with the wireless microphone transmitters at different locations. | 05-03-2012 |
20120108282 | METHODS AND APPARATUS FOR POWER CONTROL AND INTERFERENCE MANAGEMENT IN WIRELESS MICROPHONE TRANSMISSION SYSTEMS - A wireless microphone receiver is used to control transmission power and/or channel configuration of wireless microphones which communicate audio data to the wireless microphone receiver. In some embodiments the wireless microphone receiver searches for available channels, e.g., on a periodic or other basis. Based on wireless microphone receiver loading and interference considerations, channel availability may be determined and channel assignments are made. In some embodiments channel assignments are made based on wireless microphone battery status. Channel assignments to wireless microphones are communicated via a control channel. In addition to channel assignments, wireless microphone transmitter power can be controlled by the wireless microphone receiver. Commands to increase or decrease transmission power may occur as channel conditions change and/or on a recurring periodic basis. The rate of power control transmission may be relatively infrequent, e.g., a second apart in some embodiments, given that wireless microphones tend to be relatively stationary during use. | 05-03-2012 |
20120114134 | METHODS AND APPARATUS FOR CONTROL AND TRAFFIC SIGNALING IN WIRELESS MICROPHONE TRANSMISSION SYSTEMS - Methods and apparatus for controlling the communications between a wireless microphone receiver and one or more wireless microphone transmitters are described. In accordance with some embodiments a common control channel is used for communicating control signals between the wireless microphone receiver and one or more wireless microphone transmitters, while separate audio data channels are used to carry audio data traffic from each individual wireless microphone transmitter to the microphone receiver. In accordance with some other embodiment, a time division approach is used in which there are microphone transmit time periods and control signaling time periods. During the microphone transmit time periods, wireless microphone transmitters transmit audio data signals and, in some embodiment, control signals, to the wireless microphone receiver using separate frequency subbands within a frequency band. During control signaling time periods, the wireless microphone receiver transmits a control signal to a wireless microphone transmitter using the frequency band. | 05-10-2012 |

20130060631 | AD CACHE MAINTENANCE METHODS AND APPARATUS - Methods and apparatus relating to ad cache maintenance, e.g., determining when ad cache replenishment should occur, replenishing ad cache content and/or updating the content of an ad cache, on a device which supports the presentation of advertisements (ads) are described. Signals are received by a first device including an ad cache. The signals are received from other devices, e.g., devices in the direct wireless communications range of the first device. Received signals are processed and provide context information, e.g., information about the surrounding, services available, stores in the region, etc., in which the first device receiving the signals is at a given point in time. Context information is stored. As new context information is generated from received signals the newly generated set of context information is compared to a previously generated set of context information. Changes in context information are detected and used in performing ad cache maintenance operations. | 03-07-2013 |
20130060634 | METHODS AND APPARATUS FOR SELECTING ADVERTISEMENTS - Methods and apparatus related to selecting advertisements for presentation based on, e.g., received signals from devices in the proximity to a user's communications device, are described. In various embodiments a mobile device monitors for signals, e.g., peer discovery or other signals, from other devices which transmit, e.g., broadcast, advertisement related information. In various embodiments a device receives advertising information from an advertising device, e.g., AdPoint. In the case of peer to peer signaling, the AdPoint may be in close proximity to the user device receiving the advertising information. Advertising information received from devices in proximity to the user device are used in selecting an advertisement for presentation. Distance from the user device to the AdPoint transmitting an advertisement or advertisement identifier, distance to a store to which an advertisement relates, and/or distance to a location to which an advertisement relates, are taken into consideration when selecting an advertisement for presentation. | 03-07-2013 |

20130294324 | METHODS AND APPARATUS FOR MANAGING GROUP MEMBERSHIP FOR GROUP COMMUNICATIONS - Improved group communications methods which are well suited for a wireless environment are described. End nodes request that access nodes make changes in group membership information maintained at the access node. The access node responds to the requests by a response signal indicating a grant or denial of the request. Requests may be to add or remove the end node, e.g., a mobile wireless terminal, from a particular group membership list identified in the request signal. The access node maintains a detailed list of group members and uses the information to control how signals, e.g., packets, are transmitted to the group members. Group membership information may be updated at the access node at the time of handoff and/or an end node enters the cell or otherwise changes its point of network attachment. | 11-07-2013 |

20150030003 | Enhanced Techniques For Using Core Based Nodes For State Transfer - Methods and apparatus for storing, manipulating, retrieving, and forwarding state, e.g., context and other information, used to support communications sessions with one or more end nodes, e.g., mobile devices, are described. Various features are directed to a mobile node controlling the transfer of state from a first access node to a second access node during a handoff operation thereby eliminating any need for state transfer messages to be transmitted between the second access node and the first access node during handoff. Other features of the invention are directed to the use of a core network node to store state information. State information stored in the core node can be accessed and used by access nodes in cases where a mobile node does not send a state transfer message during a handoff, e.g., because communication with the first access node is lost or because such messages are not supported. | 01-29-2015 |
