Method and Arrangement for Reconfiguring Mapping of Carrier Indicator Field to Component Carrier

摘要

A method and an arrangement in a radio network node for reconfiguring mappings from Carrier Indicator Field-values to component carriers are provided. Each CIF-value is mapped to a respective component carrier comprising a respective shared data channel. Each respective shared data channel corresponds to at least one downlink control channel carrying said each CIF-value. The radio network node reconfigures mappings from CIF-values to component carriers, while at least one mapping of CIF-value to component carrier is maintained. The component carrier of said at least one mapping from CIF-value to component carrier comprises said at least one downlink control channel and a shared data channel corresponding to said at least one downlink control channel. The radio network node sends at least one of the reconfigured mappings from CIF-values to component carriers to the user equipment.

1. A method in a radio network node for reconfiguring mappings from Carrier Indicator Field-values, referred to as “CIF-values”, to component carriers, wherein each CIF-value is mapped to a respective component carrier comprising a respective shared data channel, wherein each respective shared data channel corresponds to at least one downlink control channel carrying said each CIF-value, and the component carriers are managed by the radio network node, wherein the radio network node and the user equipment are comprised in a multi-carrier radio communication system, wherein the method comprises
reconfiguring mappings from CIF-values to component carriers, while maintaining at least one mapping of CIF-value to component carrier and changing at least one mapping of CIF-value to component carrier to a mapping to another component carrier, wherein the component carrier of said at least one mapping from CIF-value to component carrier comprises said at least one downlink control channel and a shared data channel corresponding to said at least one downlink control channel, and sending at least one of the reconfigured mappings from CIF-values to component carriers to the user equipment.
