摘要： A system and method of cancelling downlink inter-channel interference between a first selected UE in one sector of a cell and a second selected UE in a second sector of said cell by using intra-eNB DL CoMP is described. UEs which are affected by ICI are identified in sectors which are adjacent to each other in the cell. A downlink CoMP operational set is formed for the identified UEs. Channel matrix blocks are estimated for the first and second selected UEs. The channel matrix blocks are representations of the channel characteristics between the first and second UE, in their respective sectors and the serving base station. The estimated channel matrix blocks are then loaded into a cross-sector channel block matrix. The inverse values of the channel matrix blocks are then calculated to form a sector specific cross-sector pre-coding matrix which is used to enable interference cancellation.

摘要： A radio user equipment (UE) mobility status is determined in a communications node. UE mobility status measurements associated with the UE communicating over a radio channel are performed. The UE mobility status corresponds to a degree of variation of the radio channel over time. Channel characteristics of the radio channel at a first time and at a second later time are determined. Based on the determined channel characteristics, a channel characteristic error metric is determined and compared to a predetermined threshold. The UE mobility status is determined based on one or more iterations of the threshold comparison.
