    摘要： A mobile station (110) selects an initial data rate for communication between base station (107) and mobile station (110). Mobile station (110) communicates the selected initial data rate to base station (107) through uplink (112). Base station (107) determines a difference level of interference condition experienced by mobile station (107) between a time when the initial data rate was selected by mobile station (110) and a time when base station (107) prepares to communicate to mobile station (110). Base station (107) selects a final data rate for transmission from base station (107) to mobile station (110) based on the determined difference level of interference condition. As such, the initial data rate may be modified to the final data rate while maximizing the down link capacity.

    摘要： A communication system includes a forward link from a base station to multiple mobile units, the forward link having multiple shared channels (SHCH's), multiple shared control channels (SHCCH's), and multiple dedicated pointer control channels (DPTRCH's), and utilizes HARQ error control for error detection and error correction. The mobile unit, when listening to the DPTRCH, uses a SHCCH pointed to by the DPTRCH to demodulate and decode data on the SHCH. Throughput problems may arise in the system when the mobile unit combines and decodes the wrong SHCH data, that is, SHCH data that is intended for a different mobile unit, or may incorrectly decodes SHCH data that is intended for the mobile unit. In order to improve the data throughput of the system, the systems employs a flush test and an energy detector test to prevent improperly decoded data blocks from corrupting properly decoded data blocks.

    摘要： A communication is provided that schedules both Distributed Virtual Resource Blocks (DVRB) and Localized Virtual Resource Blocks (LVRB) in a same frequency channel, thereby obtaining the benefits of frequency selective scheduling while minimizing the uplink feedback overhead. In one embodiment of the invention, the communication system assigns one or more downlink Physical Resource Blocks (PRBs) of multiple downlink Physical Resource Blocks (PRBs) to each user equipment (UE) given an LVRB to produce at least one reserved PRB and multiple non-reserved PRBs and assigns a part of each PRB of the multiple non-reserved PRBs to a UE given a DVRB. In another embodiment of the invention, the communication system assigns PRBs pre-reserved for localized transmission to UEs scheduled for LVRBs and assigns parts of multiple PRBs pre-reserved for distributed transmission to each UE given a DVRB.

    摘要： A method and apparatus is provided for transmitting an orthogonal frequency domain multiple access (OFDMA) signal including a synchronization channel signal transmitted within a localized portion of a bandwidth of the OFDMA signal (818), the synchronization channel signal having predetermined time domain symmetry within the localized portion of the bandwidth (816). The synchronization channel signal enables an initial acquisition and cell search method with low computational load which provides OFDMA symbol timing detection and frequency error detection by differential processing of sequence elements of the synchronization channel signal (1112) and frame boundary detection and cell specific information detection (1114) in an OFDMA system supporting multiple system bandwidths, both synchronized and un-synchronized systems, a large cell index and an OFDMA symbol structure with both short and long cyclic prefix length.
