    摘要: A base station (103) assigns a set of mobile stations (101) to a group wherein the group will share a set of radio resources (710). A shared control channel information element (501) is sent to the group of mobile stations (101) and provides a bitmap having fields for group ordering (511), resource allocations (530), failure handling resources (540), and an ordering pattern (513). If a mobile station fails to decode the shared control channel information element (501) it will access the failure handling resources in order to receive data. The failure handling channel may be persistent in some embodiments, or may be released after the mobile station is once again able to decode the shared control channel information element (501) and thereby share in the shared resource pool allocated to its mobile station group.

    摘要: A base station (103) assigns a set of mobile stations (101) to a group wherein the group will share a set of radio resources (770). A shared control channel information element (501) is sent to the group of mobile stations (101) and provides a bitmap having fields for group ordering (511), resource allocations (530), continuation resources (540) for HARQ, and an ordering pattern (513). If a mobile station requires retransmission it will access the resources indicated by the continuation resources field (54) in order to receive data. The HARQ blocks may be assigned to a mobile station based upon an index (601) which may correspond to the mobile station vocoder rate. Further, HARQ subgroups may be defined to associate subgroups of mobile stations with specific HARQ transmission opportunities on the super-frame and allocated by a rotating bitmap.

    摘要: An automatic gain control circuit uses a speech recognizer to obtain smooth automatic gain control. An analog audio input signal is converted to a digital signal by an analog-to-digital converter and delayed by a delay circuit. A frame power (or alternatively, rectified peak amplitude) detector determines the power of each frame (or alternatively, the rectified peak amplitude) of the audio input signal, after applied to the A/D converter. A linear-to-log converter converts those values to a logarithmic form (for gain control over a broad range of values). A detected speech smoothing circuit smooths the variation in the values determined by the frame power (or peak amplitude) detector. A summer subtracts the output of the detected speech smoothing means from a fixed reference level, and thus obtains an error signal from the desired reference. A gain smoothing circuit smooths the resulting error signal (which is the logarithmically-shaped gain signal). A logarithm-to-linear converter converts the logarithmic gain signal to a linear form; and a multiplier multiplies the input signal by this smoothed gain. In accordance with the invention, a speech recognizer determines whether the audio input signal represents speech. An output of the speech recognizer is used to enable the detected speech smoothing circuit and the gain smoothing means when the audio input signal represents speech. Thus AGC is not used until it is required (i.e., when speech is present).
