20080232340 | Method and Transmission Unit for Adaptive Coding, Modulation and Transmittion of Data Words in a Wireless Communication System - When transmitting data from a transmission unit to a reception unit over a channel in a wireless communication system, it has been observed that there are inherent losses in throughput, especially for a channel experiencing high channel quality variations over its frequency range. To improve the throughput over such a channel, it is proposed to: estimate the quality of each subchannel of a channel, classify the subchannels into a number of quality groups based on the estimated quality, and select a code rate per quality group. This selected code rate per quality group is then used when a data word to be transmitted is coded. Simulations have shown that by grouping the subchannels into a limited number of groups, for example one to four groups depending on the channel quality variation, a high throughput could be achieved with a minimum of signaling cost in the form of extra overhead. | 09-25-2008 |

20090109902 | METHOD AND ARRANGEMENT IN A COMMUNICATIONS SYSTEM - The object of the present invention is to provide a mechanism for a more efficient carrier search. The object is achieved by a method for sending a signal in a first node. The first node communicates with a second node via radio communication, which radio communication is performed by multi carrier transmission. The first node uses a carrier, being associated with a frequency range. The method comprises the step of transmitting an end-marker signal within or close to the frequency range. The end-marker signal is intended to be received and used by the second node for identifying the frequency range of the used carrier. | 04-30-2009 |
20100075685 | Communications session management - A scheduling algorithm is disclosed that allows mobile units, participating in an ongoing communications session, to temporary perform channel-demanding communications operations without ending the session and that is useful in the case of no free radio channels. The algorithm is based on selecting a radio channel for transmitting a radio block based on information of a previous radio channel, no which a previous radio block has been transmitted. The radio block and the previous radio block are based on common information. A mobile unit participating in the communications session selects whether to perform any channel-demanding communications operations on the selected radio channel. By limiting any such other channel-demanding operations to only the selected radio channel, the probability of loss of useful data for the mobile unit during the communications session is minimized. | 03-25-2010 |

20140086080 | METRIC COMPUTATION FOR INTERFERENCE-AWARE ROUTING - Systems and methods for computing and/or utilizing mutual information based link metrics for a link in a wireless mesh network are disclosed. In one embodiment, one or more mutual information values are computed for a link between a transmitter of a first network node and a receiver of a second network node in a wireless mesh network. Each of the one or more mutual information values is computed for a different hypothesized transmission mode for the link. One or more link metrics for the link are computed as a function of the mutual information values, where each link metric is computed based on a different one of the one or more mutual information values. In this manner, a link metric is computed for each of the one or more hypothesized transmission modes for the link. At least one of the link metrics are then provided to a routing update module. | 03-27-2014 |
