    摘要: A receiver (300) is provided that efficiently determines what transport format combination is currently being utilized by a transmitter (200) multiplexing (201) several transport channels onto a single over-the-air channel (209). The receiver (300) estimates the transmitted sequence and, not knowing the format combination being utilized, makes estimates of the information bits for each of the possible transport format combinations. CRC metrics are determined (one for each transport or data channel) for each possible transport format combination, and these CRC metrics are combined into a single transport format combination metric for the particular transport format combination being tested.

    摘要: A search metric adjustor (401) for use in a base station receiver assembly (400) which operates in a CDMA wireless communication system conveying a mobile communication signal (107), is disclosed. The search metric adjustor (401) produces an adjusted energy value (490) that is utilized by a sorter (265) in a receiver signal searcher (200) to select a set of valid time offsets at which effective demodulation of the mobile communication signal (107) may occur. The search metric adjustor (401) compares a first plurality of Walsh symbol energy values (245), output from the receiver signal searcher (200), to a second plurality of Walsh symbol energy values (342), output from a spread spectrum receiver (300). The comparison yields a walsh symbol match count (470), correlated to a predetermined energy value (480) which is then added to an energy metric (241) to produce the adjusted energy value (490).

    摘要: The present disclosure sets forth multiple embodiments of the invention. Among those embodiments is a method for managing the power of an uplink signal (e.g., an LTE PUSCH or PUCCH). The method involves determining a convolution of a first function and a second function (which may be power density functions) of the uplink signal and determining the power of the uplink signal based on the convolution. The uplink signal comprises one or both of a data signal (transmitted over a PUSCH, for example) and a control signal (transmitted over a PUSCH or PUCCH, for example). The uplink signal is transmitted over one or more subcarriers (which may be carried by resource blocks, for example).

    摘要: In a wireless communication system, a scheduler (100) determines (306) a first set of modulation and coding schemes (MCSs), each of which produces a maximum data rate for a first user, in accordance with available resource constraints (304) of the wireless communication system. The scheduler then forms, for each MCS of the first set, a second set of MCSs that produces the maximum data rate for a second user in accordance with a first residual resource (314) that remains when applying that MCS to the first user, thereby producing (316) a group of second sets of MCSs. After producing the group of second sets, the scheduler selects (324), from the first set and for the first user, a first optimal MCS corresponding to one of the group of second sets that allows a highest maximum data rate for the second user.

    摘要: A receiver (156) includes both a coherent and noncoherent demodulator. When the confidence that estimates of the channel is high, the coherent demodulator is implemented. When the confidence that estimates of the channel is low, the noncoherent demodulator is implemented. A controlling microprocessor (162) controls the selection process and also provides a signal (158) to enable the noncoherent demodulator in instances when noncoherent demodulation would most likely be better than coherent demodulation. As an example, such an instance would be immediately after handoff of a mobile station (505) from a source base-station (503) to a target base-station (502).
