| 20100027704 | Method and Apparatus for Data Transmission Based on Signal Priority and Channel Reliability - Various methods for data transmission based on signal priority and channel reliability are provided. One example method includes encoding a number of bits into coded bits including systematic bits and respective associated parity bits, the bits being encoded for transmission via channels of a multi-channel communications system including a more reliable channel and a less reliable channel. The example method also includes allocating the systematic bits to bit locations within a first stream corresponding to the more reliable channel, allocating the systematic bits to bit locations having a higher signal priority within a second stream corresponding to the less reliable channel, and allocating the parity bits to bit locations within the second stream. Similar and related example methods and apparatuses for allocating the systematic and parity bits to the respective bit locations in both the more and less reliable channels are also provided. | 02-04-2010 |

| 20100329200 | APPARATUS AND METHOD FOR ALLOCATING UPLINK RESOURCES - An apparatus is provided for allocating uplink resources in a system in which downlink component carrier bands are aggregated and uplink component carrier bands are aggregated. The apparatus includes a processor configured to perform or cause the apparatus to perform a number of functions. The functions include receiving an assignment or an indication of an assignment of one or more resource indices to the apparatus. Additional resource indices for the apparatus may be derived as a function of an assigned resource index. The assigned resource indices and/or additional resource indices may be pre-assigned to respective pairs of downlink and uplink component carrier bands, or may be mapped to uplink component carriers. The apparatus may then be enabled to transmit or may prepare for transmission uplink control signals in an uplink component carrier band in accordance with an allocation of uplink resources specified by one of the resource indices. | 12-30-2010 |
