摘要： Information is transmitted over selected, Orthogonal Frequency Division Multiplexed (OFDM) sub-channels to avoid frequencies with unacceptable congestion, noise or interference levels. Using frequency hopping, selected non-contiguous OFDM sub-channels used for transmission may vary with time. Once a group of OFDM sub-channels is selected, a power level and modulation technique may also be selected based on channel quality.

摘要： In a wireless communication system, there is a method of generating and transmitting signaling information from a user, where user control information may be appended as a header to a data block, and the data block and header may be encoded and transmitted as a signaling message from the user. In a method of scheduling a user for transmitting information, a signaling message, which may include user control information, is received from a user. A scheduling grant message that may include an allocated data rate may be transmitted in response to the received signaling message. The user control information may include one or more of buffer status information of the user, reverse pilot channel transmit power information and data related to a soft handoff (SHO) status of the user.

摘要： In the method, information from a user is transmitted over one or more communication channels of a wireless communication system by code multiplexing transmissions in the code domain. The method may include code multiplexing a first information from the user over a first channel with a second information from the user over a second channel, and determining a transmission format for the first and second channels. The transmission format may be determined based on one or more of available transmit power, transmission time interval, a coding dimension used for multiplexing, and transmit power used per code. The first information and second information are transmitted over the respective channels based on the determined transmission format.

摘要： A low-power, high-performance source-synchronous chip interface which provides rapid turn-on and facilitates high signaling rates between a transmitter and a receiver located on different chips is described in various embodiments. Some embodiments of the chip interface include, among others: a segmented “fast turn-on” bias circuit to reduce power supply ringing during the rapid power-on process; current mode logic clock buffers in a clock path of the chip interface to further reduce the effect of power supply ringing; a multiplying injection-locked oscillator (MILO) clock generator to generate higher frequency clock signals from a reference clock; a digitally controlled delay line which can be inserted in the clock path to mitigate deterministic jitter caused by the MILO clock generator; and circuits for periodically re-evaluating whether it is safe to retime transmit data signals in the reference clock domain directly with the faster clock signals.
