20090046605 | Uplink scheduling grant for time division duplex with asymmetric uplink and downlink configuration - Singalling uplink and downlink scheduling grants for a plurality of subframes in a time division duplex frame is addressed. In one aspect the allocated uplink subframes are divided into groups, so the number of groups equals the number of downlink subframes being allocated. Uplink grants for the groups are sent with the downlink grants, and for those groups that have more than one uplink subframe, the grant message also indicates which uplink subframes are included in that group. In another aspect there are two sets of grant messages, one for the uplink subframes and one for the downlink subframes. Each of the uplink grant messages is sent on a different uplink grant message, and there is a one-to-one correspondence between the uplink grant channel and the uplink subframe being scheduled by the grant. That correspondence may also be signalled with the grant messages. | 02-19-2009 |
20110281591 | METHOD AND DEVICE FOR DETERMINING ANTENNA COOPERATION SET, METHOD AND DEVICE FOR DETERMINING BASE STATION COOPERATION SET - A method and device for determining an antenna cooperation set, and a method and device for determining a base station cooperation set in the mobile communication field are provided. The method includes that a signal joint processing system obtains the channel quality between a mobile terminal and at least two base stations, determines the base stations, which are corresponding to the channel quality higher than the channel quality threshold, as the cooperation base station set of the mobile terminal. Because the channel quality between the mobile terminal and the antenna of each base station is used to determine the cooperation antenna set dynamically, therefore, the determined cooperation antenna set includes the antennae that have very strong interference to the mobile terminal, or the antennae that have been strongly interfered by the mobile station. By performing signal joint processing to the antennae, signal interference among adjacent cells can be reduced, better accuracy for detecting mobile terminal signals can be obtained, the accuracy for receiving signals by the mobile station is improved, and namely the communication quality between the mobile terminal and the base stations is improved. | 11-17-2011 |

The user uplink data scheduling method includes the steps of: acquiring an indication message transmitted from a base station for indicating user uplink data based on the multiple-periodicity mode semi-persistent scheduling; setting a periodicity offset of the multiple-periodicity mode semi-persistent scheduling; determining the periodicities of the multiple-periodicity mode semi-persistent scheduling of per two adjacent TTI bundles according to the set offset; scheduling user uplink new transmission packet data according to the determined periodicities of the multiple-periodicity mode semi-persistent scheduling. The problem that the new-transmission packet and the re-transmission packet of the same user of the multiple-periodicity semi-persistent scheduling conflict is solved, and signal overhead is reduced when TTI bundling supports the VoIP service and so on. | 12-22-2011 |

20130021999 | NETWORKING METHOD AND DEVICE FOR FREQUENCY REUSE - The present invention provides a networking method and device for frequency reuse. The method comprises dividing a total available frequency band of a system into a plurality of sub-bands, and allocating the divided sub-bands to each cell while ensuring that the sub-bands allocated to at least two cells are overlapped with each other. As a result, as compared with the networking mode in the prior art in which the sub-bands are orthogonal to each other and a frequency reuse factor is N (greater than 1), the frequency utilization rate of the system is improved. Meanwhile, as compared with the networking mode in which the frequency reuse factor is 1 in prior art, the co-channel interference between the cells is reduced. | 01-24-2013 |
