Abstract
A method and a device for data processing in a wireless communication system, in particular in a cellular system, are suggested, wherein an N-to-M control-to-data sectorization is provided to at least one mobile terminal, and wherein N corresponds to a number of control sectors and M corresponds to a number of data sectors. Furthermore, a mobile terminal for such an approach as well as a communication system comprising said device are provided.
Claims18
A method comprising:
- configuring a set of M data sectors at the site of an access node of a wireless communication system, wherein M≧1 (M is greater than or equal to 1);
- conveying data to one or more mobile terminals via beamforming from the access node to the M data sectors;
- subdividing resources available on the air interface at the site of the access node into the M data sectors;
- and
- configuring dynamically a set of N control sectors, wherein N>1 (N is greater than 1), and wherein the control sectors are arranged to convey control information of a cell of the wireless communication system to mobile terminals for controlling data transmissions between the access node and mobile terminals on the resources of the M data sectors.
An apparatus comprising at least one processor and at least one memory including computer program code, wherein the at least one memory and the computer code are configured, with the at least one processor, to cause the apparatus to at least perform the following:
- configuring a set of M data sectors at the site of an access node of a wireless communication system, wherein M≧1 (M is greater than or equal to 1);
- conveying data to one or more mobile terminals via beamforming from the access node to the M data sectors;
- subdividing resources available on the air interface at the site of the access node into the M data sectors;
- and
- configuring dynamically a set of N control sectors, wherein N>1 (N is greater than 1), and wherein the control sectors are arranged to convey control information of a cell of the wireless communication system to mobile terminals for controlling data transmissions between the access node and mobile terminals on the resources of the M data sectors.
A computer program product embodied on a non-transitory computer-readable medium, in which a computer program is stored which, when being executed by a computer, the computer program product is configured to provide instructions to control or carry out:
- configuring a set of M data sectors at the site of an access node of a wireless communication system, wherein M≧1 (M is greater than or equal to 1);
- conveying data to one or more mobile terminals via beamforming from the access node to the M data sectors;
- subdividing resources available on the air interface at the site of the access node into the M data sectors;
- and
- configuring dynamically a set of N control sectors, wherein N>1 (N is greater than 1), and wherein the control sectors are arranged to convey control information of a cell of the wireless communication system to mobile terminals for controlling data transmissions between the access node and mobile terminals on the resources of the M data sectors.
