The disclosure is directed to a mobile communication device, and method for handing off a mobile communications device between two networks. A processor in the mobile device may be used to establish a network connection with a server in a first network while supporting a call in a second network. The mobile device may also include a transceiver that receives information from the server relating to the network connection. The processor may use the information, local measurements, or both to determine whether to handoff the call to the first network.

The disclosure is directed to a mobile communication device, and method for controlling power saving features at the mobile device. A processor in the mobile device may be used to establish a network connection with a server in a first network. The mobile device may also include a transceiver that initiates transmission of a message to the server to determine if an incoming call request has been received via a second network. Advantageously, the transceiver is in a low power mode of operation for a selectable time interval when not communicating with the server.

A wireless device and method of operating the device is disclosed. The wireless device is capable of communicating with multiple networks. The wireless device includes a transceiver configured to communicate with either one of two networks over a wireless medium. Each of the two networks has a different air interface protocol. The wireless device also includes a user interface having a keypad, display, and/or similar devices. A processor in the wireless device may be configured to select either one of the two networks for wireless communications with the transceiver. In at least one embodiment, the processor is configured to communicate with the transceiver using the air interface protocol for the selected network, and communicate with the user interface using a root protocol regardless of the network selected.

A forward link (FL) RLP and a reverse link (RL) RLP that are different in design are used for data transmission on the forward and reverse links, respectively. The asymmetric RLP designs may be quantified by, e.g., different feedback mechanisms and/or different data transmission mechanisms used for these RLPs. The FL RLP may utilize a negative acknowledgment (NAK)-based feedback mechanism whereas the RL RLP may utilize an acknowledgment (ACK)-based feedback mechanism. The NAK-based FL RLP may transmit each RLP frame once in sequential order and retransmit RLP frames out of sequence when not received correctly. The ACK-based RL RLP may transmit RLP frames in sequential order, one frame at a time until the frame is received correctly or the maximum number of transmissions have been attempted. Timers with adaptive values computed based on actual traffic conditions may be used to facilitate data transmission by the NAK-based FL RLP.

Techniques for managing peak-to-average power ratio (PAPR) for multi-carrier modulation in wireless communication systems. Different terminals in a multiple-access system may have different required transmit powers. The number of carriers to allocate to each terminal is made dependent on its required transmit power. Terminals with higher required transmit powers may be allocated fewer carriers (associated with smaller PAPR) to allow the power amplifier to operate at higher power levels. Terminals with lower required transmit powers may be allocated more carriers (associated with higher PAPR) since the power amplifier is operated at lower power levels. The specific carriers to assign to the terminals may also be determined by their transmit power levels to reduce out-of-band emissions. Terminals with higher required transmit powers may be assigned with carriers near the middle of the operating band, and terminals with lower required transmit powers may be assigned with carriers near the band edges.
摘要:
Providing for interference reduction and/or avoidance utilizing backhaul signaling between wireless access points (APs) of a wireless access network (AN) is described herein. By way of example, an interference avoidance request (IAR) can be issued by an AP to reduce signal interference on forward link (FL) and/or downlink (DL) transmissions by neighboring APs. The IAR can be routed via a backhaul network and/or over-the-air via access terminals (ATs) coupled with the AP or one or more interfering APs. Upon receiving the IAR, an interfering AP can determine reduced transmit power levels for FL and/or RL transmissions and respond to the IAR. The response can include reduced power levels and can be sent via the backhaul network or OTA. By employing the backhaul network in full or in part, interference avoidance can be conducted even for semi-planned or unplanned heterogeneous networks coupled by the backhaul.
