20090029698 | APPARATUS, AND ASSOCIATED METHOD, FOR FACILITATING MOBILE NETWORK SELECTION BY A GAN-CONNECTED WIRELESS DEVICE - Apparatus, and an associated method, for facilitating manual PLMN selection of a GAN-connected wireless device. While maintaining connection of the wireless device with a serving GANC, a request is made for a PLMN listing of the potentially available PLMNs with which the wireless device can communicate. The request message is sent to the network, and the PLMN listing is created by a PLMN listing creator. The listing is provided to the wireless device in a response message returned to the device. Selection of a selected PLMN is made, subsequent to the selection, the de-registration of the connection of the wireless device with the serving GANC is permitted. | 01-29-2009 |

20110069669 | SYSTEM AND METHODS FOR SENDING AND RECEIVING PAN (PIGGY-BACKED ACK/NACK) SO AS TO AVOID DECODING CONFUSION - There may be ambiguity when ACK/NACK information is transmitted. In some cases the ambiguity may arise because a bit may be either a padding bit, or an ACK/NACK bit having the same value as a padding bit. In other cases, the ambiguity may arise where it is unclear whether the ACK/NACK is in respect of a first transmission of a data block, or a subsequent transmission of the same data block. Various schemes provided to address this. In some cases, the mobile station is mandated to apply a consistent behaviour. Over time, the network can deduce the behaviour. In some cases the mobile station transmits signaling that conveys the behaviour. | 03-24-2011 |
