US 2016/0112965 A1 · ANCHOR CARRIER IN A MULTIPLE CARRIER WIRELSS COMMUNICATION SYSTEM

Abstract

Multiple downlink (DL) and uplink (UL) carriers can enhance wireless communication between nodes and user equipment (UE). Among the carriers, it is beneficial to have some special, by configuration designated carriers to provide synchronization, system information, paging, data and control for multi-carrier enabled UEs. Thereby, overhead system information can be reduced. For instance, synchronization and paging for a certain cell are not provided on all carriers. A carrier can provide backward compatibility for single carrier UEs for access, synchronization, broadcast, and new control region within the data region of the legacy terminals. Coordination between nodes for selecting anchor carriers that mitigate interference and for transmit power control for non-anchor carriers provide further network performance advantages.

Dependent claims

A method performed by a cell for coordinating carrier transmission between nodes, comprising:

transmitting a first carrier to provide wireless service to a first user equipment (UE) while a neighboring cell transmits a second carrier to provide wireless service to a second UE;
and
coordinating with the neighboring cell by adjusting transmit power of a non-anchor carrier of the cell or the neighboring cell to reduce a jamming interference between the cell and the neighboring cell.

A computer program product for coordinating carrier transmission between nodes, comprising:

at least one computer readable storage medium storing computer executable instructions that when executed by at least one processor implement components comprising:
a first set of instructions for causing a computer to transmit at a cell a first carrier to provide wireless service to a first user equipment (UE) while a neighboring cell transmits a second carrier to provide wireless service to a second UE;
and
a second set of instructions for causing the computer to coordinate with the neighboring cell by adjusting transmit power of a non-anchor carrier of the cell or the neighboring cell to reduce a jamming interference between the cell and the neighboring cell.
