摘要： A method and apparatus includes a scheduling entity (308) for scheduling and transmitting the superframe (402) across a communication network (200). The controller (310) coupled with scheduling entity (308) groups the subscriber unit (304) into one of the plurality of groups. The scheduler entity (308) assigns a coding scheme for each group and encodes each frame of the superframe (402) based upon the assigned coding scheme for the group, to which the frame is to be transmitted. The transceiver (316) coupled with controller (310) via hardware interface (314) receives the encoded superframe and transmits the superframe to the plurality of subscriber units in the communication network (200).

摘要： A technique for operating a wireless communication device includes assigning re-transmission identifiers, such as hybrid automatic repeat request (HARQ) channel identifications, automatic repeat request (ARQ) channel identifications, and ARQ Identifier Sequence Numbers, to at least a first re-transmission identifier group and a second re-transmission identifier group, wherein each re-transmission identifier group is associated with a different quality of service parameter. The technique identifies whether a committed quality of service is met for a connection based on whether a communication on the connection is associated with the first re-transmission identifier group or the second re-transmission identifier group.

摘要： A system includes a polyphase multirate filter and a controller which, responsive to detecting a data stream: measures a current phase relationship between a current resampling filter input clock signal and a current multirate output clock signal; identifies, based on a mapping of the measured phase relationship within a pre-generated quantized mapping table, an initial polyphase filter coefficient index corresponding to the measured phase relationship; selects, based on the initial polyphase filter coefficient index identified, a corresponding polyphase filter component from within the multirate filter; configures the multirate filter to pass data from the data stream through the corresponding polyphase filter component to generate an initial output data sample; updates the initial polyphase filter coefficient index to a calculated next polyphase filter coefficient index value, in response to a request for generation of a next output data sample; and self-corrects the multirate filter responsive to a pre-identified error condition.

摘要： An apparatus and method for uplink time synchronization in a communication system includes a first step 602 of receiving uplink data from a user equipment. A next step 604 includes storing a time error of the uplink data along with a time stamp. A next step 620 includes integrating the time error to provide an accumulated time error. A next step 606, 626 includes dumping the accumulated time error upon the time stamps of the accumulated data meeting a timing condition. A next step 610 includes comparing the accumulated time error against a threshold. A next step 616 includes scheduling a time advance with the user equipment if the accumulated time error exceeds the threshold.
