摘要:
A method and system for method for transmitting data in a communication network employing HARQ. The method includes a first step 502 of grouping data to be transported into a first group and a second group in accordance to a decision parameter, such as data size. A next step 504 includes concatenating data from the first group and encoding into a multi-user packet. A next step 502 includes encoding the data into a plurality of data packets. A next step 506 includes assigning available traffic resources to encoded packets. A next step 506 includes transmitting at least a first transmission of the encoded packets. A next step 510 includes reassigning a portion of said traffic resources for which a positive acknowledgement has been determined to uninitiated packets or to assist with one or more ongoing transmissions.

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.

A wireless communication infrastructure entity assigns a plurality of schedulable wireless communication entities to a group wherein each entity is assigned a location within the group. The infrastructure entity indicates which of the plurality of schedulable wireless communication entities assigned to the group have been assigned a radio resource, for example in a first bitmap (510), and indicates radio resource allocation policy information (520) and indicates a weighting for each assigned wireless communication entity, for example, in a second bitmap (530), to the schedulable wireless communication entities that have been assigned a radio resource.

A communication system distributes, in the time domain, acknowledgment transmissions by a group of access terminals sharing a same time domain resource. A position of one or more access terminals in the group of access terminals is determined and each of the one or more access terminals then sends an acknowledgment transmission, such as an acknowledgment or negative acknowledgement, in a time slot that is N time slots after the shared time domain resource, where N is a function of the position of the access terminal in the group of access terminals.

A digital receiver (200) and transmitter (300), wherein the digital receiver includes a plurality of antennas (202) for receiving uplink radio frequency signals; a plurality of analog to digital converters (210) for converting the received radio frequency signals into digital signals; a switched digital down converter (214) for down converting one of the digital signals to a baseband IF signal; and a channel processor (228) for recovering one of a plurality of communication channels contained within the baseband IF signal.

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.

During operation a wireless terminal will receive instructions assigning it to a group of wireless terminals sharing a common set of resources. The terminal will also receive an overflow allocation policy indicating resources that are to be utilized if there are more assigned resources that group resources.
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).
