| 20090280823 | EFFICIENT PAGING MECHANISM WITH SCALABLE BANDWIDTH ALLOCATION - The invention relates to an improved paging procedure for mobile nodes in a mobile communication system. A UE in idle mode is paged by a network entity via a selectable frequency subband of the system bandwidth. For every resource block, comprising part of the paging message or a diversity repetition thereof, a respective frequency subband is selected based on various parameters. These parameters may include: load in the subbands, UE capability in the tracking area and/or importance of paging information within the resource block. Furthermore, additional parity bits may be transmitted instead of the diversity repetition of the paging message, wherein the resource blocks, comprising the additional parity bits, are also transmitted via selectable frequency subbands. Thereby, the delay for changing from the idle to the active state of a mobile node may be reduced by increasing reliability of paging message transmission and resources may be utilized more efficiently. | 11-12-2009 |

The memory associated to the HARQ process is divided into several sub-areas, which are addressable by an identifier. Then, when data is received, same is stored in one of the sub-areas. By providing more than one sub-area for one HARQ process, it is possible to actually use one HARQ process for two (or more) different received data units, being from the same data flow or from a different data flow. The actual sub-area of the HARQ process for storing data units can be either freely selected at the receiving end or is indicated by an identifier associated with the data. Furthermore, persistent scheduled data is transmitted in units, scheduled at fixed time intervals. Thus, a control signaling field, usually used for indicating new units, can be used to store the identifier. | 02-24-2011 |
