20110189986 | MESSAGE-BASED EXCHANGE OF ACCESS POINT PILOT SIGNATURE INDICATORS - An access point is identified based on a plurality of pilot signatures. Here, in addition to transmitting a pilot signal that is encoded (e.g., spread/scrambled) using a particular pilot signature, an access point transmits a message that includes at least one indication of at least one other pilot signature. For example, an access point may use one PN offset to generate a pilot signal and transmit a message that identifies at least one other PN offset. An access terminal that receives the pilot signal and the message may then generate a pilot report that identifies all of these pilot signatures. Upon receiving a handover message including this pilot-related information, a target network entity with knowledge of the pilot signatures assigned to that access point may then accurately identify the access point as a target for handover of the access terminal. | 08-04-2011 |

20110243067 | DELAYED AUTOMATIC REPEAT REQUEST (ARQ) ACKNOWLEDGMENT - Disclosed are examples in which the acknowledgement channel is used for retransmitting a frame received with error. A receiver is configured to transmit an acknowledgment for a frame when the frame is decoded following receipt of the last Pilot Control Group (PCG) of the same frame. The transmitter is configured to receive the acknowledgment of an earlier frame during a subsequent frame, and not to retransmit the earlier frame. The two frames may be adjacent. During connection setup negotiation, the system can determine the values of ack_mask1 defining allowed times for the receiver to acknowledge successful decoding of the subsequent frame, and ack_mask2 defining allowed times for the receiver to acknowledge successful decoding of the earlier frame. The two mask values provide non-overlapping allowed times, so the receiver can acknowledge within the subsequent frame (1) successful decoding of the earlier frame, and (2) successful decoding of the subsequent frame. | 10-06-2011 |

20130176942 | DEVICES AND METHODS FOR FACILITATING OVERHEAD MESSAGE UPDATES IN WIRELESS COMMUNICATIONS SYSTEMS - Access terminals are adapted to facilitate reception of overhead messages. According to one example, an access terminal can determine whether it is at least substantially stationary. The access terminal may receive one or more sequence numbers corresponding to a subsequent overhead message. In response to being at least substantially stationary, the access terminal can ignore the subsequent overhead message when the corresponding sequence numbers are the same as stored sequence numbers corresponding to a previously obtained overhead message, even when the previously obtained overhead message is more than six hundred seconds old. According to another example, a network node may transmit an overhead message including a corresponding sector indicator and sequence numbers. When the sector indicator and the sequence numbers are the same as a previously received and stored sector indicator and sequence numbers, the access terminal can ignore the overhead message. Other aspects, embodiments, and features are also included. | 07-11-2013 |

20130252609 | METHODS AND DEVICES FOR FACILITATING ACCESS TERMINAL REGISTRATION WITH A REGISTRATION SERVER - Access terminals are adapted to communicate with registration servers to enable a registration server to perform timer-based registrations on behalf of an access terminal. The access terminal can cease performing such timer-based registrations as long as the registration server performs the registrations, and may power down until event data is available for transmission or reception. When a registration server performs timer-based registrations on behalf of an access terminal, the registration server can periodically communicate with a network entity to conduct the timer-based registrations for the access terminal. The network entity can receive a timer-based registration message from a registrations server for registering an access terminal. In response to such a message, the network entity can register the access terminal. Sensors and controllers may be used with some embodiments to collect and analyze data and for potentially taking action. Other aspects, embodiments, and features are also claimed and described. | 09-26-2013 |

20130301437 | APPARATUS AND METHOD FOR CONTROLLING AN ACCESS PROBE TRANSMIT POWER ACCORDING TO A REVERSE LINK UNDERLOAD CONDITION - Apparatus and methods are disclosed for adapting the power of an access probe transmission, in accordance with a reverse link underload indicator provided by the base station. In one example, the base station can transmit a one-bit reverse link underload indicator as an information element broadcasted within a general page message (GPM). Here, the reverse link underload indicator can indicate whether a measured rise-over-thermal (RoT) at the base station is less than a given threshold. The access terminal may accordingly reduce the initial transmit power of an access probe transmission in the case of a reverse link underload condition, as this condition would indicate that the base station could accommodate reduced power access probe transmissions without substantially decreasing the probability of a quick detection of the access attempt. Other aspects, embodiments, and features are also claimed and described. | 11-14-2013 |
