20100233962 | INTER-CELL INTERFERENCE CONTROL IN AN UPLINK MULTI-CARRIER RADIO COMMUNICATIONS SYSTEM - A multi-carrier cellular radio communication system includes a serving base station associate with a serving cell currently serving a mobile radio and a non-serving base station within range of the mobile radio and associated with a non-serving cell. The mobile radio can transmit to the serving base station at the same time over multiple radio frequency carriers. An estimate is made of inter-cell interference in the non-serving cell caused by uplink transmission by the mobile radio over one or more of the multiple radio frequency carriers over which the mobile radio is currently simultaneously transmitting. If the estimated inter-cell interference in the non-serving cell exceeds a predetermined threshold, then the inter-cell interference in the non-serving cell is reduced or limited by managing radio resources so that the estimated inter-cell interference in the non-serving cell is or becomes less than the predetermined threshold. | 09-16-2010 |

20120008563 | Power Backoff for Multi-Carrier Uplink Transmissions - Teachings presented herein provide reduced computational complexity and/or memory requirements for a mobile terminal to determine the power backoff required for a multi-carrier uplink signal. In particular, the mobile terminal determines whether its power headroom falls below a pre-defined power headroom threshold, indicating that it is headroom limited. If so, it5 quantizes power allocated to each carrier of the multi-carrier uplink signal according to a pre-defined quantization policy. In doing so, the mobile terminal thereby reduces the possible configurations that may be selected for the multi-carrier uplink signal. Thus, in one embodiment, the mobile terminal stores the required backoff in a look-up table for only the configurations that may be selected when the mobile terminal is headroom limited. This relieves 10 the memory requirements of the mobile terminal as compared to storing the required backoff for all possible configurations of the multi-carrier uplink signal. | 01-12-2012 |
