Abstract: Embodiments of methods are provided for transferring a user identity from one wireless communication device to another in a wireless communication system having a network system controller. A first device sends a deactivation request to the network controller, which includes information identifying the first device and a second device. The second device sends an activation request to the network system controller, which includes the information identifying the second device. The first device also sends repertoire information to the second device via the network system controller. The repertoire information is associated with the first device, and is selected from a group consisting of personal phone books, stored messages, stored recent call logs, and calendar information.

Abstract: Apparatus, which has a multilayer protocol stack for processing incoming messages, determines PTT state from messages received from a peripheral over a wireless serial communication channel. The apparatus: receives, from the peripheral, a sequence of messages comprising a plurality of data messages (e.g., RFCOMM messages), wherein each of the data messages provides an indication of a PTT state for the apparatus, and wherein the sequence of data messages is received over a short range wireless data path for exchanging priority data that comprises a wireless serial communication channel and that is different from a short range wireless data path for exchanging non-priority data. A pattern detector in the apparatus performs a pattern matching process, within the first two layers of the multilayer protocol stack, to determine the PTT state indicated by each of the data messages and sets the apparatus to have the determined PTT states.

The distribution by the license owning unit to other devices in the cluster is at the lowest resolution of any of the devices of the cluster.

Abstract: Disclosed is a method for a femtocell to reduce interference with an overlapping macrocell. The femtocell determines soft-frequency-reuse (“SFR”) information of the macrocell. From that information, the femtocell determines which frequency sub-channels are assigned by the macrocell for its cell-center users and which frequency sub-channels are assigned for cell-edge users. (Cell-edge users are given a higher transmission power profile in order to overcome potential interference with neighboring macrocells.) Then, the femtocell selects from the cell-center user frequency sub-channels for transmission to the femtocell's users. By transmitting on the cell-center user frequency sub-channels, the femtocell reduces interference with the overlapping macrocell. The femtocell continues to update its knowledge of the macrocell's SFR information and re-assigns frequency sub-channels as the SFR changes.

Abstract: A communication device performs a method for establishing a fast path for signaling priority data. The method includes: establishing a first short range wireless data path to a second communication device for exchanging non-priority data; and establishes a second autonomous short range wireless data path to the second communication device, for exchanging priority data, wherein the second short range wireless data path comprises a wireless serial communication channel such as a radio frequency communication Bluetooth (RFCOMM) channel. An application layer in an upper layer stack of the communication device establishes both the first and the second short range wireless data paths. Non-priority data communicated to the second communication device along the first short range wireless data path is processed by the application layer. However, priority data communicated to the second communication device along the second short range wireless data path bypasses the application layer.

Abstract: A hybrid TDMA-CSMA MAC protocol is provided for allocating time slots within a frame having a structure in which transmission time is divided into a first number of actual TDMA time slots and a second number of “virtual” CSMA time slots. Each of the nodes in a multi-hop network can transmit a Highest Slot Number (HSN) field. Each time one of the Hello messages is received from a neighbor node, a given node can calculate variables based on the HSN field. The given node can use these variables to calculate a ratio of the first number to the second number. This ratio can be dynamically adjusted depending upon the traffic conditions observed by nodes within the multi-hop ad hoc network at any particular time to thereby change the relative percentages of the frame which are allocated for a TDMA portion and a CSMA portion of the frame.

Abstract: A method of detecting an on-channel signal and synchronizing signal detection with correcting for DC offset errors in a direct conversion receiver is presented. A received signal is digitized, and a state machine operates to detect the presence of an on-channel signal. If the signal is not detected, a mixed mode training sequence is initiated in which the DC offset errors in both an analog and digital received signal path are corrected. While training, processing of the digitized samples by a digital signal processor and a host controller is suspended (while they are put into battery save mode) and the gain provided to subsequently received signals is minimized. The DC offset correction circuitry is bypassed and put into battery save mode at predetermined periods when DC offset correction is not performed.

Abstract: A first communication device (e.g., a radio) and a second communication device (e.g., an accessory) implement a wireless device pairing procedure to exchange numerical credentials so that the devices can subsequently form a link for communications using electromagnetic radio signals. The accessory transmits a beacon comprises a pairing request. Upon a user bringing the radio and accessory in close enough proximity, the radio receives the beacon using near-field apparatus included in the radio. In response to receiving the beacon, the radio initiates a pairing procedure, wherein the pairing procedure comprises a data exchange between the radio and accessory, and wherein the beacon and the data exchange comprise a non-propagating radio signal generated using the near-field apparatus. Upon completing the pairing procedure, the radio forms a link with the accessory to communicate using propagating electromagnetic radio signals.
