Abstract: The present disclosure describes a method and apparatus for transmit power calibration in a frequency division multiplexed wireless system (100). The method may include receiving (315) an uplink scheduling grant at a user equipment (120), establishing (320) a desired power level based on at least the uplink scheduling grant, and setting (325) hardware power settings based on the desired power level. The method may also include transmitting (330) data in a first subframe at a first power level based on the hardware power settings, measuring (335) the first power level in the first subframe, and determining (340) a difference between the desired power level and the measured first power level. The method may additionally include modifying (345) the hardware power settings based on the difference and transmitting (350) at a second power level based on the modified hardware power settings in a next transmission corresponding to the transmission in the first subframe.

Abstract: Embodiments include methods and apparatus associated with wireless multicast and/or broadcast services. A base station (102, FIG. 1) transmits data codes (504, 604, 702, FIGS. 5-7) within a radio frame (300, FIG. 3). The data codes are Code Division Multiple Access (CDMA) data codes, in an embodiment. The base station also transmits a Time Division Multiplexed (TDM) synchronization code (502, 608, 706, FIGS. 5-7), in an embodiment. The base station discontinuously transmits (1004, FIG. 10) a portion of a radio frame slot that is coincident in time with a duration of the TDM synchronization code, in various embodiments. The discontinuously transmitted portion of the radio frame slot may include Transport Format Combination Indicator (TFCI) bits (510, FIG. 5), pilot bits (710, FIG. 7), or data bits (612, FIG. 6), in various embodiments. A base station's transmissions may be synchronous in time and frequency with the transmissions of other base stations.

Abstract: A method in a wireless communication device may include receiving a plurality of sub-frames, each sub-frame having time-frequency resource elements, at least one of the sub-frames having a control channel. In some implementations, the plurality of sub-frames forms a continuum of concatenated sub-frames. Each of the plurality of resource allocation fields of the control channel may indicate a resource assignment to the wireless communication device based on a channel quality report, as well as resource assignments in sub-frames of the continuum of concatenated sub-frames. At least one sub-frame of the continuum of concatenated sub-frames may include information indicating that at least some of the resource assignments are frequency diverse.

Abstract: Disclosed is a method for mobile assisted sleep mode to reduce current drain in packet based mobile systems. The method comprising the step of receiving (102) from a network a channel condition threshold. Then, monitoring (104) a channel condition while in sleep mode. Then exiting (110) sleep mode in response to the determination (108) that the monitored channel condition is greater than the channel condition threshold.

Abstract: A method and apparatus is provided for generating a decision value (809) for use in signal acquisition and channel estimation. In a first embodiment a receiver (850) is provided including at least two spatially diverse antennas (600, 601) which can receive different, e.g. consecutive, segments of the same signal, a signal characteristic (e.g., energy) determination stage (840) for processing the different segments to determine the separate energy values for the segments, and an accumulator (808) for accumulating the energy values so as to form the decision value or statistic (809). Additional embodiments are also provided.

Abstract: The embodiments of the present invention provide a method and apparatus for assigning enhanced mobile subscriber units to a telecommunications network. In a first embodiment, a network identifies a classmark of a mobile subscriber unit and determines whether the mobile has an enhanced performance capability, for example an interference cancellation capability. If the mobile is enhanced, it is assigned to a high fractional load timeslot. If not, a low fractional load timeslot is allocated. Handover procedures are controlled in a like manner, wherein mobile capability is determined prior to assigning timeslots during handover.

Abstract: An improved turbo code based incremental redundancy includes a first step of puncturing a data stream for a first transmission to provide a set of first unpunctured trellis sections. A next step includes puncturing a data stream for a second transmission to provide a set of second unpunctured trellis sections. A next step includes incremental redundancy combining the first and second transmissions of the trellises to provide non-adjacent first and second unpunctured trellis sections. The above arrangement results in a uniform distribution of punctured and unpunctured bits to provide lower errors.
