A method () for limiting transmission power of a communication device () having a plurality of transceivers (). The method can include determining a desired maximum transmission power and determining a plurality of power contribution factors. Each of the power contribution factors can be associated with a respective one of the transceivers. The method also can include determining an expected transmission power based on, at least in part, a sum of the power contribution factors. Further, responsive to the expected transmission power exceeding the desired maximum transmission power, the power contribution for at least one of the transceivers can be selectively reduced or terminated.

Monitoring and control of transmit power in a multi-modem wireless communication device

A method and system for selecting scanning rates in a multi-mode communication device is disclosed herein. The method can include the step of&#x2014;at a multi-mode communication device&#x2014;measuring at least one parameter associated with an interaction between a first network and the multi-mode communication device. The method can further include the step of&#x2014;in response to measuring the parameter&#x2014;selecting a scanning rate of the multi-mode communication device for a second, different network that interacts with the multi-mode communication device. In the method, the first network and the second network can have independent synchronization procedures.

A receiveras a component in a wireless communication deviceand a corresponding method are used for receiving a multi-carrier communication signal and determining a timing offset thereof. The receivercomprises a controllerto perform a correlation on each of a plurality of sub-carriers comprising the multi-carrier signal to provide a plurality of timing offsets. A quality metric corresponding to each of the plurality of timing offsets may be employed to select the best timing offset. Alternatively, a set of timing offsets whose quality metric exceed a threshold may be averaged. Either the best or average timing offset is used for processing all the sub-carriers of the multi-carrier signal.

A system, wireless device () and method reduce the peak-to-average power of a transmitter by creating at least two sampled carrier data streams, running each carrier through a separate delay block, mixing each carrier over in frequency an appropriate amount, resulting in at least two frequency division multiplexed signals, and combining the at least two frequency division multiplexed signals together. The four sampled carrier data streams may each have a bandwidth of 25 kHz. Each separate delay block is less than 20% of its corresponding symbol time. The transmitter may be used to transmit wideband integrated digitally enhanced network (WiDEN) signals.

Subcarrier time offsets for improved peak-to-average power of a transmitter

Receiver bandwidth is dynamically altered during operation (with respect to, for example, filter bandwidth and/or filter center frequency) as a function, at least in part, of communication resource allocation.

Reception method and apparatus

A system () grants inbound channel capacity using frequency and time diversity by wirelessly transmitting on a first () of a plurality of outbound channels () a first () of a plurality of first inbound channel grant signals () for controlling transmission of a multiple channel mobile station () on a plurality of inbound channels (). Thereafter, on a second () of the plurality of outbound channels a second () of the plurality of first inbound channel grant signals is wirelessly transmitted. Furthermore, the system () grants inbound channel capacity using time diversity by wirelessly transmitting on the first () of the plurality of outbound channels all of a plurality of second inbound channel grant signals () for controlling transmission of a single channel mobile station () on one () of the plurality of inbound channels are transmitted.

Multiple inbound channel granting method and apparatus

A selective call receiver (24) that receives signals transmitted by orbiting satellites (A, B) uses certain information transmitted by the satellites to calculate an estimate of its position. Using that estimate and other information, the selective call receiver (24) is able to save power by disregarding certain information contained in transmitted signals that are not intended for it.
