Multi-Cell Transmissions

A method comprising:

• receiving at a selected one of a plurality of radio access network entities, each capable of both coordinating a multi-cell transmission and following the coordination by another entity of a multi-cell transmission, an indication that said selected one radio access network entity is to operate as a coordinating entity;
• deciding at said selected radio access network entity on physical parameters for a multi-cell transmission;
• and distributing physical parameter information about said multi-cell transmission from said selected radio access network entity to others of said plurality of radio access network entities.

A radio access network entity dynamically configurable between a first mode in which said entity coordinates a multi-cell transmission and a second mode in which said entity follows the coordination by another entity of a multi-cell transmission.

An apparatus for use at a radio access network entity, said apparatus comprising:

• a processor and memory including computer program code, wherein the memory and computer program code are configured to, with the processor, cause the apparatus to:
• in response to an instruction from a management entity switch the radio access network entity between a first mode in which said radio access network entity coordinates a multi-cell transmission and a second mode in which said radio access network entity follows the coordination by another entity of a multi-cell transmission.

A computer program product comprising program code means which when loaded into a computer controls the computer to:

• in response to an instruction from a management entity switch the radio access network entity between a first mode in which said radio access network entity coordinates a multi-cell transmission and a second mode in which said radio access network entity follows the coordination by another entity of a multi-cell transmission.

A method comprising:

• selecting as a coordinating entity one of a plurality of radio access network entities, each capable of both coordinating a multi-cell transmission and following the coordination by another entity of a multi-cell transmission;
• sending to said selected entity an indication that said selected one radio access network entity is to operate as a coordinating entity;
• and sending to others of said plurality of radio access network entities an indication that said others are to follow the coordination by another of said plurality of radio access network entities.

A management entity configured to select, as a coordinating entity, one entity from amongst a plurality of radio access network entities each capable of both coordinating a multi-cell transmission and following the coordination by another entity of a multi-cell transmission.

An apparatus for use at a radio access network entity, said apparatus comprising:

• a processor and memory including computer program code, wherein the memory and computer program code are configured to, with the processor, cause the apparatus to:
• select, as a coordinating entity, one entity from amongst a plurality of radio access network entities each capable of both coordinating a multi-cell transmission and following the coordination by another entity of a multi-cell transmission.

A computer program product comprising program code means which when loaded into a computer controls the computer to:

• select, as a coordinating entity, one entity from amongst a plurality of radio access network entities each capable of both coordinating a multi-cell transmission and following the coordination by another entity of a multi-cell transmission.
