Abstract: A base station is configured to transmit user data to a wireless device upon a first carrier. The base station identifies, from a set of transmission resources that is nominally allocated for transmission of user data upon the first carrier, a subset of transmission resources that is also nominally allocated for transmission of a reference or control signal either by the base station upon a second carrier or by a neighboring base station upon the first carrier. The base station selectively transmits user data to the wireless device upon the first carrier exclusive of this identified subset of transmission resources. The device in some embodiments obtains information indicating that the base station is selectively transmitting user data upon the first carrier exclusive of the subset in this way. Based on this information, the device recovers user data received upon the first carrier exclusive of the subset of transmission resources.

Abstract: Mechanisms for efficient transmission of large amount of download data from a base station to a user equipment in a multi-carrier that minimizes power consumption on the user equipment are described. When multiple component carriers are to be used to transmit the download data, the base station informs the user equipment. The base station transmits on the anchor carriers without wait after informing the user equipment and transmits on the non-anchor carriers after waiting a predetermined delay. The predetermined delay provides time to allow the user equipment to activate the receiving resources and be ready to receive the download data over the non-anchor carriers. In this manner, the user equipment can be in a power conservation mode and activate the receiver resources only when needed.

Abstract: A radio network node in a multi-carrier radio communication system reconfigures mappings of Carrier Indicator Field values (CIF-values) to component carriers.

The radio network node sends the changed second mapping to a user equipment (UE) comprised in the multi-carrier radio communication system. The UE receives the reconfigured mappings and reconfigures the UE to use the mappings for communication in the multi-carrier radio communication system.
