Abstract
The present invention provides a method, respective apparatuses, system and computer program product for obtaining channel state information in a coordinated multi-point transmission/reception communication network. The method includes allocating a first sounding resource to at least one of a plurality of user equipment in a coordinated multi-point transmission/reception communication network for transmitting sounding reference signal to a base station of a serving cell, and allocating a second sounding resource to the at least one user equipment for transmitting sounding reference signal to a base station of an interfering cell, wherein the first and the second sounding resource are different from each other.
Claims12
A method comprising:
- allocating a first sounding resource and a second sounding resource to at least one of a plurality of user equipment in a coordinated multipoint transmission/reception communication network,
- wherein the first sounding resource is allocated for transmitting a sounding reference signal to a base station of a serving cell,
- wherein the second sounding resource is allocated for transmitting a sounding reference signal to at least one base station of an interfering cell,
- wherein the first and the second sounding resources are different from each other in the coordinated multi-point transmission/reception communication network, wherein the first and second sounding resources are each set separately based on predetermined configuration parameters, and
- wherein in response to a conflict in a time domain of the first sounding reference signal and the second sounding reference signal, the first sounding reference signal is discarded based on a predetermined criterion.
An apparatus comprising:
- a controller configured to allocate a first sounding resource and a second sounding resource to at least one of a plurality of user equipment in a coordinated multi-point transmission/reception communication network,
- wherein the first sounding resource is allocated for transmitting a sounding reference signal to a base station of a serving cell,
- wherein the second sounding resource is allocated for transmitting a sounding reference signal to at least one base station of an interfering cell,
- wherein the first and the second sounding resource are different from each other in the coordinated multi-point transmission/reception communication network,
- wherein the first and second sounding resources are each set separately based on predetermined configuration parameters, and
- wherein in response to a conflict in a time domain of the first sounding reference signal and the second sounding reference signal, the first sounding reference signal is discarded based on a predetermined criterion.
An apparatus comprising:
- a receiver configured to receive allocation information of a first sounding resource and a second sounding resource,
- wherein the first sounding resource is allocated for transmitting a sounding reference signal to a base station of a serving cell in a coordinated multi-point transmission/reception communication network,
- wherein the second sounding resource is allocated for transmitting a sounding reference signal to at least one base station of an interfering cell in the coordinated multi-point transmission/reception communication network,
- wherein the first and the second sounding resources being different from each other in the coordinated multi-point transmission/reception communication network, and
- wherein the first and second sounding resources are each set separately based on predetermined configuration parameters, and
- wherein in response to a conflict in a time domain of the first sounding reference signal and the second sounding reference signal, the first sounding reference signal is discarded based on a predetermined criterion.
